Shipman Engine Manufacturing Co. seems to have superseded the Shipman Engine Co., which was active around 1890 to 1894; we suspect that that firm superseded A. H. Shipman.

By early 1898 Shipman Engine Manufacturing Company was in receivership but still operating. That did not seem to last long, as we can find no information on the company's operations after that time.

The two iterations of this company made a small steam engine intended for driving a sewing machine, lathe, or other small machine. They apparently also continued production of the "Demas" scrollsaws from A. H. Shipman.

• Thanks to Dave Flaig for reporting this maker to us. He reported the name as "T. E. Shipman Engine Manufacturing Co." but we can find no other occurrence of "T. E. Shipman" in relation to that era in Rochester.
• We found nothing in the Cornell "Making of America" archives or the University of Michigan "Making of America" archives. A web search came up dry, as did a patent search.
• We did find information in Google Books. Volume 53 of The New York Supplement, containing the decisions of the Supreme and Lower Courts of Record of New York State (August 25-November 17, 1898), in a decision regarding the receivership of Punnett Cycle Manufacturing Co., says, "The Shipman Manufacturing Company, as the assignee of the receiver of the Shipman Engine Manufacturing Company..."
