In 1882 or '83, Christian J. Weinman founded the Novelty Machine Works; Edward E. Euchenhofer joined as partner a year later. In about 1890 they formed a joint stock company and changed the name to Dayton Gas & Gasoline Engine Co., and in 1895 they changed the name to Dayton Gas Engine & Manufacturing Co. The two men sold that business in 1896 and formed a new partnership, Weinman & Euchenhofer.

At some point, Weinman and Euchenhofer parted ways, with Weinman continuing under the name of C. J. Weinman & Co. and Euchenhofer operating as E. E. Euchenhofer and then as Dayton Machine Works; Euchenhofer continued operating under that name until at least 1915.

In 1899, Euchenhofer patented a power hacksaw. One example of this hacksaw has "MFG’D BY E. EUCHENHOFER DAYTON.O. U S A” cast into it. Another example bears only the name of dealer Strong, Carlisle & Hammond, but we presume that this saw was also made by Euchenhofer. We have also seen listings for the "Victor" power hacksaw, made by Dayton Machine Works.

  Edward E. Euchenhofer, a member of the firm of Weinman & Euchenhofer, machinists, at 20 and 22 North Canal street, was born in Dayton October 3, 1852, and is a son of Frederick H. and Caroline (Disher) Euchenhofer.

  In 1888, E. E. Euchenhofer, in partnership with C. J. Weinman, founded the Novelty Machine works, on St. Clair street, Dayton, and under that name the business was conducted seven years, when it was incorporated under the name of the Dayton Gas & Gasoline Engine company, but a year later was changed to the Dayton Gas Engine & Manufacturing company, the concern being converted into a joint stock company, with a capital of $40,000 and officered with E. E. Euchenhofer as president. The present firm of Weinman & Euchenhofer was formed in May, 1896.

  ... Edward E. Euchenhofer was educated in the public schools of Dayton until fourteen years of age, when he entered the employ of Mr. Mueller, first as errand boy, and afterward as clerk, until seventeen years old, when he began an apprenticeship with Brownell & Kielmeier, manufacturers of engines. With this firm he remained five years, acquiring a full knowledge of machinery and becoming an expert in the manufacture and construction of steam engines in every detail. His next step was to enter into business on his own account, but at the end of two years be abandoned this to engage in the dry goods and notion trade. After a year thus spent, he returned to his former employers, for whom he did faithful service for several years; was next appointed assistant engineer of the city water-works, and nine months later was appointed chief engineer, holding this responsible position for five years. While serving in this capacity, Mr. Euchenhofer invented and patented an automatic device for boilers, for feeding boiler scale solvents, and this patent has, by reason of its acknowledged efficiency, met an extensive sale throughout the country. His next step in business was the formation of a partnership with Mr. Weinman in the enterprises above mentioned. Messrs. Euchenhofer & Weinman are the inventors and patentees of many valuable devices in connection with engines and machinery.

  ...Christian J. Weinman, senior member of the firm of Weinman & Euchenhofer, machinists, Nos. 22-24 Canal street, Dayton, Ohio, was born in Dayton May 14, 1858, and is a son of Christopher H. and Anna B. (Werner) Weinman, both of whom were natives of Germany, and of whom only the former is still living, Mrs. Weinman having been called to rest in March, 1889.

  ...Christian J. Weinman received his education in the public schools of his native city, and was about eleven years of age when he began working, during vacation, at anything he could find to do. At the age of sixteen he entered the Buckeye Iron & Brass works, served an apprenticeship, then worked as a journeyman until 1882 or 1883, when he established the Novelty Machine works on Third street, and a year later admitted Edward E. Euchenhofer as a partner. This business was continued by the firm for about seven years, when it was made a stock concern under the name of the Dayton Gas & Gasoline Engine company. In March, 1895, the name was changed to the Dayton Gas Engine & Manufacturing company, which was continued until May, 1896, when both Mr. Weinman and Mr. Euchenhofer sold out their stock in the company and established their present business. Mr. Weinman is an inventor of rare ability and his patents have received the seal of public approbation wherever introduced, the productions of the firm being welcomed in all parts of the United States, as well as in other countries.
