Moore Steam Pump, Patent Model


The model was submitted to the U.S. Patent Office with the application for the patent issued to Ila N. Moore, of Battle Creek, Michigan, June 23, 1891, no. 454753.

The feature of this pump power is a piston with steam ports in the piston leading to the ends of the cylinder and a valve fitted to slide on the elongated and reduced barrel of the spool-shaped piston controlling the admission of steam through the steam ports. The object is to provide a steam pump requiring no steam chest. Steam is admitted at the center of the cylinder through two short passages connecting directly with the steam pipe. Exhaust is to a chamber on the opposite side of the cylinder. A hollow tail rod, gland, and housing form part of the exhaust passage. The piston valve, which slides on the barrel of the piston, is actuated in part by the pressure of the steam and in part by the motion of the piston. Packing rings on the outside of the valve heads operate across the steam inlet ports in the cylinder wall and the lands between grooves in the bore of the valve operate across the ports in the piston barrel.
