Sewell and Cameron Steam Pump, Patent Model

<< >>
This model was submitted to the U.S. Patent Office with the application for the patent issued to William Sewell and Adam S. Cameron, of New York, New York, May 10, 1864, no. 42694.
The model represents a direct-connected steam pump in which the water piston rod is keyed in a socket in the end of the steam piston rod, so that the two may be disconnected when it is desired to operate the pump by hand. The socket is sufficiently long to serve as a guide for the water piston rod, and a suitable rock shaft and capstan head is provided for working the pump by hand.
The purpose of the combination is to provide a hand pump for the various purposes for which a pump might be required aboard a vessel when steam is down and the steam pump cannot be used, while eliminating some of the piping that would be necessary if separate pumps were provided.
This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A. Taylor.
