Size: Approx. 10.0 cu.ft.


George Clinton Sheldon, a native of New York residing in Nehawka, Nebraska, demonstrated his first concrete mixer at a local picnic in the fall of 1913. During that first year in business, six machines were produced. The following year, Sheldon manufactured mixers at a small shop behind the Nehawka post office. By 1919 Sheldon boasted that 4,138 of his concrete mixers had been sold. That same year, a 64 foot x 108 foot steel factory building was erected.

George Sheldon described his concrete mixer as “…a common barrel so mounted in a frame with the aid of castings of my design, as to be rotated to perform the mixing operation and tilted to allow dumping into a wheel barrow or other receptacle.” Sheldon’s plan was to sell his machine directly to his intended consumer – the farmer – who could use the mixer for small jobs on the farm, such as foundations, floors, culverts, water tanks, troughs, well curbs, and platforms.

The Sheldon Manufacturing Company was incorporated on April 1, 1920, with authorized capital stock of $250,000. From the first year total sales figure of $153,000, sales had climbed to an average of $50,000 per month in 1920. In the early 1920s, business remained good as the Sheldon mixer was exhibited at various state and county fairs and agricultural conventions and additions to the factory were made so that parts, previously purchased from outside suppliers, could be produced on-site. In 1921 George Sheldon was able to boast that the Sheldon mixer was being used more extensively on American farms and by small contractors than all other available mixers. In addition, the Sheldon mixer was being exported to a large number of foreign countries, including Argentina, Australia, Ireland, and Venezuela.

During this period Sheldon added hog crates to his product line. The Sheldon Trusty Hog Crate was advertised as the only crate on the market that conformed to the railway express companies’ size requirements. He also developed and sold saw rigs, loaders, and over-sized mixers custom-made for gold mining. Sheldon suggested, too, that his original mixer could be used for the mixing of a timely product during this period of prohibition – home brew.

By 1922 financial problems were beginning to beset the company. With money tied up in advertising, Sheldon’s papers reflect his great interest in the use of advertising to sell his product – Sheldon was having trouble making payments on various loans. The recession of the early 1920s, plus the advent of ready-mix concrete, dealt crippling blows. In 1923 the Stover Manufacturing Company of Freeport, Illinois, took over the marketing of the entire output of the Sheldon Manufacturing Company, leaving Sheldon to concentrate on the “manufacturing end of the business.” Apparently, this did not help as the Sheldon Manufacturing Company declared bankruptcy that same year.

After this, Sheldon continued to operate his business in a small way, assembling units one at a time on a per job basis. This he continued to do well into the 1950s, though his income came primarily from his work as a Kelvinator dealer, through a bottled gas business, and from farm property.

During World War II various pieces of machinery from the Sheldon factory were leased to a Dallas, Texas, firm for $1,500 annually. The factory building was used briefly by armament manufacturers as well. A 1957 proposition to sell the shop to a feed manufacturing business failed.

George C. Sheldon died in Nehawka, Nebraska, on March 27, 1965.


This collection consists of six boxes, three oversize bundles, and an oversize drawer of manuscript material arranged in seven series: 1) Correspondence, 1899-1931; 2) Administrative and Legal Records, 1916-1965; 3) Financial Records, 1915-1948; 4) Advertising Materials, 1915-ca. 1925; 5) Blueprints and Drawings, ca. 1916-ca. 1922; 6) Diaries, 1911-1959; and 7) Miscellany.

The bulk of this collection relates to the business conducted and products made by the Sheldon Manufacturing Company of Nehawka, Nebraska. Particular emphasis is placed on the first invention and best-seller of the company, the Sheldon Cement Mixer. The collection reflects, first, the growth and optimism of the Company, led by George C. Sheldon in the years immediately preceding and following World War 1 and, then, the problems encountered during the business slump of the 1920s which culminated in the company’s declared bankruptcy in 1923.

The correspondence, 1899-1931, of Series 1, deals primarily with the business conducted by the Sheldon Manufacturing Company. Most of this series is comprised of outgoing correspondence of the company covering the years 1913-1914, 1920-1923, and 1931. This material provides explanations on the operation of the Sheldon Cement Mixer; suggestions on uses for the machine; discussions on business operation procedures; information on orders placed with suppliers; ideas on the marketing and advertising of Sheldon products; information on new products, such as Sheldon Hog Crates and the Sheldon Saw Rig; and sales figure tabulations. By 1922 the Sheldon Manufacturing Company was facing financial hardships and the correspondence reflects George Sheldon’s ultimately unsuccessful attempts to deal with creditors and suppliers. Testimonial letters, 1912-1921, written to Sheldon praising the Sheldon Cement Mixer, and a small amount of Sheldon family correspondence is also included in this series. One personal letter from Sheldon to his family in New York, dated March 26, 1913, describes damage caused by the tornado that struck Nehawka, Omaha and the surrounding areas on March 23, 1913. Sheldon writes about the number of dead and injured people as well as farm animals. He describes in detail the weather conditions just before the tornado and the destruction it caused. He also expresses concern about a missing family member.

Administrative and legal records of the Sheldon Manufacturing Company, 1916-1965, can be found in Series 2. Included are the company’s articles of incorporation and by-laws; minutes of board and stockholders meetings, 1921-1941; patents, 1916-1923; copyrights, 1923-1924; trademarks and labels, 1920-1936; contracts, 1916-1963; stock offering materials, 1920-1926; bankruptcy papers, 1923; and documents relating to the settlement of the Sheldon estate, 1965.

Series 3 is comprised of financial records, 1915-1948. Included are sales books, 1915-1919, which provide a daily record of products sold and money taken in. Information on money paid out for material, advertising, commissions, and other sorts is also noted. Cash books, 1919-1920, which list accounts and show credit and debit amounts; sale records, 1920-1921, arranged on a monthly basis which show dollar amounts taken in by dealers, jobbers, export, and through mail order; and payroll records, 1919-1943, listing employees, dates and hours worked, pay rate, and amount paid. A financial report on the Sheldon Corporation, 1946, and miscellaneous financial notes, 1917-1948, can also be found in this series.

The advertising materials of Series 4 consist of catalogues, circulars, fliers, advertisement layouts and artwork, newspaper advertisements, invoices for advertising orders, and an address book which records advertisement materials mailed to customers. This particular series provides excellent information on how one particular company, the Sheldon Manufacturing Company, promoted its products to its market during the years 1913-ca.1925. In a larger historical context, this material is valuable as documentation of the growth in and importance of advertising as that industry flourished in the 1920s.

Series 5 consists of blueprints and drawings, ca. 1916-ca. 1922, which provide detailed sketches of parts and machinery, and specifications in the Sheldon Manufacturing Company’s factory. Larger drawings and blueprints showing the factory’s floor plans and views of parts and assembled concrete mixers are also found in this series.

The diaries of George C. Sheldon, 1911-1959, in Series 6 contain very little information on the business of the Sheldon Manufacturing Company. Although a few of the diaries from the early years do note business calls made, many of the entries from the late 1920s and after detail weather and crop conditions, work done as a hauler of materials to and from local farmers, and Sheldon’s business as a Kelvinator dealer. By 1929 Sheldon’s Kelvinator trade appears to be a more important source of income than the cement mixer operation. Although Sheldon’s cement mixers were made until at least 1959, it appears that they were manufactured on a per job basis.

Series 7 contains a variety of topical material designated as “Miscellany.” Included are materials relating to the Sheldon Manufacturing Company’s exports; fair participation; other lines of products; sales letters; jobbers material; and price lists. Also included in this series are catalogues and advertisements from competing manufacturers of cement mixers.

Note: The photograph portion of this collection [RG4074.PH] contains 395 prints and 50 negatives relating to the Sheldon Manufacturing Company of Nehawka, Nebraska. For additional information about the Sheldon Manufacturing Company, see:

About History Nebraska
History Nebraska was founded in 1878 as the Nebraska State Historical Society by citizens who recognized Nebraska was going through great changes and they sought to record the stories of both indigenous and immigrant peoples. It was designated a state institution and began receiving funds from the legislature in 1883. Legislation in 1994 changed History Nebraska from a state institution to a state agency. The division is headed by Interim Director and CEO Jill Dolberg. They are assisted by an administrative staff responsible for financial and personnel functions, museum store services, security, and facilities maintenance for History Nebraska.
