c. 1929 Advance-Rumely Do-All Tractor


 This Do-All Tractor was made sometime around 1929 by the Advance-Rumely Company in La Porte, Indiana. About 3,192 Do-All tractors were made between 1928 and 1931. This tractor was built with a 4 cylinder gasoline engine with a 3 1/2" x 4 1/2" bore and stroke. It has two forward speeds and one reverse speed, and it weighs about 3,702 pounds. It was reportedly the first row-crop tractor used around Henderson, Nebraska, a town in York County, about 35 miles east of Grand Island.
 The Nebraska Tractor Test for the Do-All Tractor was #154, performed between October 29th and November 24th, 1928. The Do-All was rated at 16.3 HP at the drawbar and 21.6 HP on the belt. You can view a pdf of this test by clicking or touching here.

The Advance-Rumely Company, the maker of six tractors and one steam engine in Stuhr Museum’s exhibit, had a long history before its incorporation in 1915. Its history can be traced back to Meinrad Rumely, a German immigrant to the United States in 1848. In that year, at the age of 25, Meinrad moved to Canton, Ohio, where his older brother, Jacob, lived. In 1850, he moved to nearby Massillon, Ohio, to join his brother, John, who was working for Russell & Company. Not long after moving to Massillon, Meinrad left for La Porte, Indiana, where he became a blacksmith in 1852. After his brother, John, joined him in La Porte, the two brothers created M. & J. Rumely Company. They made their first thresher by 1857 and their first steam stationary engine in 1861. Their products found a ready market.
In 1882, after adding portable and traction steam engines to their product lines, Meinrad bought out John’s portion of the company and renamed it M. Rumely Company. Meinrad’s company continued to grow during the last two decades of the 19th century, producing thousands of steam traction engines and other products. When Meinrad died on March 31, 1904, his two sons, William and Joseph, became the leaders of the company. Edward Rumely, Joseph’s son, also joined the company. By 1907, Edward took a leading role, guiding the company to even more products, especially to the development of a tractor that ran on a fuel other than steam. In 1907, he got in touch with John Secor, an engineer who had been experimenting with low-grade distillate fuels in internal-combustion engines. Meinrad had been familiar with Secor’s work in the 1880s, and Meinrad’s son, William, discussed Secor’s work with Edward as they talked about the work of Rudolf Diesel.
When Edward Rumely and John Secor discussed development of a tractor with an internal-combustion engine, Secor decided to join the company. When Secor joined Rumely so too did Secor’s nephew, William Higgins. Higgins, an inventor himself, had been working on a kerosene carburetor, patenting his invention with the help of his uncle. For a reported $213,000 in stock, Rumely obtained these two inventive minds and their patents. With the addition of Secor and Higgins, the company began working on what would become the famous OilPull series of tractors. After testing the first two-cylinder kerosene-fueled engines in 1909, the M. Rumely Company began production of their first OilPulls in 1910. Although the shop crew referred to the tractor as Kerosene Annie, Edward Rumely and his secretary came up with the name OilPull. On February 21, the La Porte factory finished the first OilPull, a Type B 25-45, weighing about 24,000 pounds. Before the end of the year, the factory had completed its first 100 OilPulls.
Building on the company’s continued success, Edward decided to expand through acquisition. In October 1911, Rumely bought the Advance Thresher Company of Battle Creek, Michigan. At about the same time, Rumely also purchased the Gaar-Scott Company of Richmond, Indiana, the maker of the oldest steam engine tractor in Stuhr Museum’s exhibit. Both Advance and Gaar-Scott had long histories, developing steam engine tractors and other products for the agriculture market. In 1912, Rumely added Northwest Thresher Company, including Northwest’s 24-40 gasoline tractor. Rumely continued making the Northwest tractor as a 15-30, calling it the Gas Pull, until 1915.
Despite its recent acquisitions and its success with the new OilPull, the M. Rumely Company saw a drop in sales in 1913. After 2,656 OilPull sales in 1912, the company only had 858 OilPull sales in 1913, including Stuhr’s Type E 30-60. Having already borrowed money to acquire other firms, the company was in trouble. On January 1, 1914, Edward Rumely resigned from the company. At the end of 1914, the company had sold only 357 OilPulls. In January 1915, the M. Rumely Company filed bankruptcy and was appointed Finley Mount as its receiver. An Indianapolis lawyer, Mount trimmed off the company’s later acquisitions, leaving the company with the Rumely factory in La Porte and the Advance Thresher factory in Battle Creek. The company was renamed the Advance-Rumely Thresher Company and continued to do business without the Rumely family. Secor and Higgins continued as employees and made even more developments to their tractors.

It was at this time, during the late 1910s and early 1920s, that the company made Stuhr Museum’s Universal steam engine tractor, as well as its Types F, G, H, and K OilPull tractors. By 1924, with the popularity of smaller tractors increasing, Advance-Rumely needed to develop smaller tractors to compete with the Fordson and other tractor models. The company created the Types L, M, and R, and then Types W, X, and Z tractors, all smaller than their predecessors. By 1929, the company went even further, introducing the Do-All, an even smaller all-purpose tractor which is also represented in Stuhr’s exhibit. In 1930, Finley Mount and Edward Rumely, who had returned to the company after a failed stint in newspaper publishing, convinced Otto Falk, the head of Allis-Chalmers, to acquire Advance-Rumely. On June 1, 1931, Allis-Chalmers absorbed the company and became the fourth-largest farm equipment manufacturer in the U.S. After the acquisition, Advance-Rumely’s tractors came to an end as its factory inventories came to an end.

c. 1933 Massey-Harris GP 15-22 Tractor


 This GP (General Purpose) tractor (serial #301611) was reportedly used on a farm near Fairmont, Nebraska, a town in Fillmore County, about 60 miles east-southeast of Grand Island. About 3000 GP 15-22 tractors were made from 1930 to 1936 (serial #300001-303001). The GP 15-22 was made to pull two plows. It was built with a 4 cylinder engine, a 4" x 4 1/2” bore and stroke, and was rated at 1200 RPM. It has four gears, three forward and one reverse. First gear could reach about 2.2 mph, second gear about 3.2 mph, and third gear about 4.0 mph. The reverse speed could reach about 2.5 mph. This tractor weighs about 3,861 pounds.
 The Massey-Harris GP's first Nebraska Tractor Test was #177, performed between May 5th and May 27th, 1930. It tested at 19.91 HP at the drawbar and 24.84 HP on the belt. You can view a pdf of the original tractor test #177 by clicking or touching here. The GP was tested again between May 22th and June 12th, 1931. During this second test, the GP was rated at 16.79 HP at the drawbar and 22.50 HP on the belt. This second test, Nebraska Tractor Test #191, can be viewed as a pdf by clicking or touching here.
 Although you may not see the identifying label from the walkway, this Massey-Harris GP has a Hercules engine manufactured by the Hercules Motors Corporation of Canton, Ohio. This engine has two patents. The first is dated June 4, 1918. The second is dated September 20, 1921. This tractor also has a magneto starter made by the American Bosch Magneto Corporation of Springfield, Massachusetts, and a Murphy Safety Switch gauge made by the Rochester Manufacturing Company of Rochester, New York. The Murphy Safety Switch was patented by Frank W. Murphy, filed on November 12, 1941 and acquired on September 19, 1944. The patent number is 2358729 and can be viewed as a pdf by clicking or touching here. The Hercules engine and Bosch magneto may be original to this tractor. The Murphy Safety Switch was apparently added later.

1922 Velie Roadster


This roadster was made by the Velie Motors Corporation in Moline, Illinois in 1922. Before the creation of Velie automobiles, Willard Lamb Velie, Sr., founded the Velie Carriage Company in 1902. After nearly six years in the buggy business, Velie, a grandson of John Deere, decided to make automobiles, incorporating the Velie Motor Vehicle Company in 1908.  Up until 1915, Velie advertised his factory’s cars in the John Deere Plow Company catalog and through Deere implement dealers.
 During World War I, however, Velie prospered from government contracts and reorganized his company as the Velie Motors Corporation.  In 1924, Willard took ill, and Edwin McEwen essentially ran the company.  By 1927, Willard, Sr. returned to running the company and appointed his son, Willard Lamb Velie, Jr. as vice-president and general manager.  Willard, Sr. died on October 24, 1928 of an embolism, and Willard, Jr. died on March 20, 1929 of heart disease.  With the death of the two Velies, the Moline factory became part of Deere and Company, and the Velie automobile ceased to be produced.

c. 1903-1915 Henney Covered Buggy


(If you have read the web page for the Henney Surrey, most of the information below is repeated from that entry. Near the bottom of this entry, however, is some information on the Queen No. 2 heater found on the floor of this buggy.)
 John W. Henney, Sr., the founder of the Illinois company that made this covered buggy and the nearby two-seated surrey, was born in Centre County, Pennsylvania in 1842, the son of Jacob Henney who was also a buggy maker.  In 1854, John moved west with his family, settling in Cedarville, Illinois where his father set up a new buggy shop.  John grew up around buggies, learning about the business not only from his father in Cedarville but also from other businessmen throughout the region.  In 1864, as the railroads opened up the West to new settlers, John ventured out to Kansas City where he worked in the buggy trade for three years. By 1867, he found himself back in Cedarville taking over his father’s business, a local and not very successful enterprise according to an 1888 biography.1
 John, however, had the energy and the desire to turn the business into something bigger.  By 1876, he had succeeded in growing his company to the point where he needed to build a larger shop.  At this time he also brought in his brother-in-law, Oliver P. Wright, as a partner.  J. W. Henney & Company, as the business was called at this time, employed about fifteen to twenty men, and Henney became a locally known name.  Wanting to expand business further, in 1879, Henney traveled around the region, visiting cities such as Dubuque, Iowa and establishing relationships with Mississippi River trading companies.
 As his business continued to grow, Henney decided to move his shop from Cedarville to Freeport, a move which cut out about six miles of road travel each way and gave the company more immediate access to the nearest railroad.  By 1880, the Freeport plant was making about 500 buggies and wagons a year.  It was around this time that J. W. Henney & Company became the Henney Buggy Company, and Henney and Wright were joined by Daniel C. Stover, an inventor and founder of a local bicycle company, as stockholders.  In 1883, as the company expanded production even more, five more men became stockholders.  By 1887, the company was producing over 4,000 buggies and wagons in a year.  Its growth was remarkable.
 Before the turn of the century, however, the company ran into problems.  On June 12, 1898, because of disputes within the ranks of the company, John Henney, Sr. quit.  He stepped down from running the operation of the business; and, in 1900, he left Freeport to manage a Henney sales agency in Kansas City.  In Henney's absence, Daniel Stover, one of the company's other stockholders, leased the company for five years beginning on November 3, 1898.  During those five years, the Henney Buggy Company became the Henney Buggy Company, D. C. Stover & Company, and Proprietors.  At first, the company continued to be strong, producing several thousand vehicles each year; however, by 1902, the Freeport company went into receivership.
 Fortunately for the Freeport plant and its employees, the leaders of a nearby Moline, Illinois company came to the rescue.  On October 2, 1902, the Moline Plow Company, known for its farm implements, entered into a contract with Stover to purchase all of Henney’s output from November 1, 1902 to July 1, 1903 and to market those vehicles through its head office, branches, and agencies.  Going a step further, on June 3, 1903, the Moline company exercised an option to purchase the Henney company, its factory, patents, and machinery outright.  Moline’s stockholders reorganized the company, taking over on July 20, 1903.  In addition to reorganizing the company, Moline rehired John Henney, Sr., who had recently moved back to Freeport, as superintendent of the plant. Over the next few years, John returned the company to its successful past.
 Around 1906, John W. Henney, Jr. entered the company; and by 1910, he had succeeded his father as superintendent of the Henney plant in Freeport.  Under John, Jr.'s leadership, the Henney plant produced thousands of horse-drawn vehicles for markets throughout the United States.  In 1911, despite the company’s continued success, John, Jr. resigned.  Even without a Henney at the helm, the company continued to be successful, manufacturing thousands of vehicles over the next four years.
 Although buggies continued to sell over those four years, it became apparent to the Moline company’s leaders that the automobile was quickly surpassing the buggy in popularity.  Wanting to keep up with the changing times, in 1915, the Moline Plow Company ceased production of its many models of vehicles at the Freeport plant.  By April, 1916, the company had shifted production from horse-drawn vehicles to the Stephens automobile; and, for the next eight years, the Freeport plant would make the Stephens.
 The year 1915 marked the end of an era for the Henney factory. Over nearly five decades of buggy production, the Henney companies in Cedarville and Freeport manufactured over 200,000 vehicles.  Henney's lines of vehicles grew just as the company's overall output grew.  In 1893, John Henney, Sr.'s company advertised 26 different styles of horse-drawn vehicles.  By 1896, the company had expanded to 49 different styles.  In 1904, under the ownership of the Moline Plow Company, Henney advertised 53 different vehicle styles.  And by 1914, even as the automobile was replacing the horse-drawn buggy on American roads, Moline advertised 98 different styles of vehicle made at the Henney Buggy Company plant.



Even though the Henney factory in Freeport stopped making horse-drawn vehicles in 1915, many Henney vehicle owners continued to travel on their buggies, carriages, and wagons throughout the 1910s and beyond.  Fortunately for those of us living nearly a century after the Freeport plant made this buggy, the Moline Plow Company placed a metal plaque on the back of this buggy as well as a paper one-year "guaranty" on the wood seat of this buggy.  That guarantee (pictured above) and that metal plaque enable us to date this buggy to between 1903, when Moline acquired the Henney factory outright, and 1915, when Moline ended production of the Henney buggies.




 Although you may not be able to see it from the walkway, this buggy has a foot heater on its floor in front of the seat. The heater is a “Queen No. 2” Heater made by the Lehman Brothers Company of New York, New York. It is about 14 inches long and has a drawer on one end. In order to use the heater, the rider would place a heated Lehman Coal into the drawer. The coal produced no smoke or smell, only heat. On cold trips, a buggy rider welcomed the heat from the buggy’s floor. A rider might even wrap a blanket around his or her body and around the heater to take advantage of the emanating warmth. An 1898 advertisement stated that a two-cent coal could provide eight hours of heat.

Notes
1 The early part of Henney’s history, especially as it revolved around John W. Henney, Sr. is from Portrait and Biographical Album of Stephenson County, Ill., Containing Full Page Portraits and Biographical Sketches of Prominent and Representative Citizens of the County, Together with Portraits and Biographies of All the Governors of Illinois, and of the Presidents of the United States (Chicago: Chapman Brothers, 1888), pp. 468-470.  The remainder of the history here comes from Thomas A. McPherson, The Henney Motor Company: A Complete History (Hudson, WI: Iconografix, 2009), pp. 10-26.  After leaving the buggy factory in 1911, John Henney, Jr. moved to Chicago.  With the help of his father and other partners, John, Jr. started another company in Freeport in 1915, making bodies for funeral coaches, buses, and ambulances.  By the mid-1920s, Henney began making bodies for cars; and, when Moline stopped producing the Stephens and closed the old Henney plant in Freeport in 1924, John, Jr. purchased the plant and moved his newer business into the former Henney Buggy Company facilities.  In 1927, Henney reorganized and renamed his company the Henney Motor Company.  It would become a very successful enterprise, remaining in business until the 1950s.

c. 1921 Hercules Model E 1 1/2 HP Engine



 This Model E engine (serial #239840) was made by the Hercules Gas Engine Company in Evansville, Indiana, probably around 1921. It has a 1 1/2 HP engine and was rated at 550 RPM. The Model E was made between 1914 and 1921. Over 210,000 Model E engines appear to have been built.
 The Hercules Gas Engine Company's history has been traced back to William H. McCurdy and the Brighton Buggy Works of Cincinnati, Ohio, founded in 1894. Supplying Sears, Roebuck and Company with buggies, McCurdy's company grew to the point where he needed larger facilities to meet demand. In 1902, McCurdy moved the company to Evansville, Indiana and renamed it the Hercules Buggy Company. From the early 1900s to 1909, the Evansville factory produced the Sears Motor Buggy, its first experience with gasoline engines. Even after Sears moved the manufacture of their motor buggies to Chicago, the Hercules Buggy Company continued to produce bodies for the motor buggies.
 In 1912, the situation for McCurdy and for Sears changed. Sears had been purchasing its stationary engines from the Holm Machine and Manufacturing Company in Sparta, Michigan. When Holm could not meet the demand of Sears for its engines, McCurdy was asked to become the new supplier. In 1912, the Hercules Buggy Company purchased the Holm Company and moved the manufacturing of stationary engines to Evansville where a new factory was being built. On November 8, 1912, the Hercules Gas Engine Company was formed. In early 1914, the first Hercules engines rolled off the line. They would be the first of about 400,000 engines produced by the Hercules Gas Engine Company until the factory closed in 1934.
 If you walk a short distance down the line of gas engines here in this exhibit, you will find a Hercules Model S 1 3/4 HP engine, made in Evansville around 1927, probably for Sears, Roebuck & Company.

Early 20th Century New Holland Type P Farm Engine



 This gasoline engine was made by the New Holland Machine Company in New Holland, Pennsylvania. It has a 1 1/2 HP engine and is rated to run at 300 to 600 RPM. This particular engine has serial #9835 as well as two patents. The patents were both issued on April 7, 1903, to Abraham M. Zimmerman, the founder of the company. One of the patents, for a vaporizer for gas engines, is Patent 724648 which you can view by clicking or touching here. The other, for a sparking mechanism for engines, is Patent 724649 which you can view by clicking or touching here.

 Abraham M. Zimmerman was born on a farm near New Holland, in Lancaster County, Pennsylvania, in 1869. After a few years as an apprentice, Zimmerman moved to New Holland and started his own workshop where he repaired a variety of machines for local farmers. His initial business was called the New Holland Machine Shop, and, by 1899, Zimmerman had developed his New Holland Cob and Feed Mill which made him locally known. He added gasoline engines to his products by 1901. In 1903, the year he incorporated his company as The New Holland Machine Company, his factory employed about 21 workers. The New Holland Machine Company changed hands several times over the years since the early 1900s, and is, today, part of Case-New Holland, one of the world's largest agricultural equipment manufacturers.

Early 20th Century One-row Tongueless Riding Cultivator



 This riding cultivator can be dated to as early as 1904, and it may have been made by the Emerson Manufacturing Company of Rockford, Illinois. A farmer used this cultivator to dig up unwanted plants, and to turn over and break up the soil along both sides of a row of corn. The farmer would hitch this cultivator to two horses that would pull it over a row of growing corn. The cultivator would pass over the corn while the four small shovels turned over the earth and dug up the plants alongside the corn. The farmer could adjust the shovels by pulling on the levers in front of his seat.

 Without any clear information about this cultivator, it is difficult to identify its manufacturer. Between 1850 and 1930, there were hundreds, possibly thousands of companies that made cultivators and cultivator attachments. Even though the manufacturer of this cultivator did not place its name on this machine, we can locate several part numbers as well as two patent dates.  The patent dates have led us to identify this cultivator as one manufactured by the Emerson Manufacturing Company. The patent dates are February 6, 1900 and June 7, 1904, and they appear to refer to patents 642795 and 761734, respectively. You can view Patent 642795, Gustav Jernberg's cultivator patent assigned to the Emerson Manufacturing Company, by clicking or touching here. You can view Patent 761734, Lewis E. Waterman's cultivator patent assigned to the Emerson Manufacturing Company, by clicking or touching here. In 1909, the Emerson Manufacturing Company would become the Emerson-Brantingham Company, maker of two tractors as well as a threshing machine here in this exhibit.

Early 20th Century Wheelbarrow Sprayer


Throughout the late 1800s and early 1900s, many North American prairie farmers used insecticides to protect their crop fields, orchards, gardens, and livestock from unwanted insect pests.  They applied some insecticides in powder form and others in liquid form, mixing the powder compound with water or another liquid.  If applying an insecticide in liquid form, farmers turned to a sprayer like Stuhr Museum’s wheelbarrow sprayer to distribute the insecticide solution.
At the time this sprayer was made in the early 1900s, insecticide sprayers and containers were made in a variety of sizes and styles.  The size and style depended often on the needs of the farmer.  Some sprayers and containers, especially ones used for gardens, were smaller and carried by hand.  Others roughly the same size as Stuhr’s sprayer were strapped to people’s backs like a backpack or knapsack and used to spray larger areas such as an orchard.  Sprayers and containers larger than Stuhr’s example were often pushed or pulled around on a cart or a wagon by people or horses, enabling a farmer to spray a larger crop field.  The wheelbarrow pump sprayer here at Stuhr Museum was reportedly used to spray livestock and fruit trees.


A wheelbarrow pump sprayer made by the Hayes
Pump & Planter Company of Galva, Illinois.


In terms of the insecticides used, prairie farmers from the mid-1800s through the early 1900s had a variety of chemical solutions from which to choose.  During the late 1800s, farmers often used chemicals called Paris green or London purple to kill unwanted insects.  Paris green may have been first used on the American prairie in 1867 to combat the Colorado potato beetle.  London purple was a by-product of the fiber dyeing industry and was a finer powder than Paris green, more easily mixed with water for spraying.  Although farmers continued to use Paris green and London purple in the early 1900s, many farmers began to turn to lead arsenate, including Swift’s Arsenate of Lead, as their insecticide of choice.

Some of the unwanted prairie insects in the late 1800s and early 1900s were the Colorado potato beetle (Leptinotarsa decemlineata) which attacked potatoes; the Plum Curculio (Conotrachelus nenuphar), a weevil that laid its eggs inside apples and other fruits; the chinch bug (Blissus leucopterus) which consumed wheat and corn; the wheat stem maggot (Meromyza americana Fitch) which consumed wheat; the fruit tree bark beetle (Scolytus rugulosus Ratz) which lived underneath the bark on trees, especially oak trees; and the codling moth (Cydia pomonella) which consumed fruit.
