Description
JOHN H. MGGOWAN, OF CINCINNATI, OHIO.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 122,475, dated January 2, 1872.
I, JOHN H. MOGOWAN, of Cincinnati, Hamilton county, Stat-e of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a speciication:
N atnre and Objects of Invention.
My invention consists of improvements upon the invention patented by myself and Theodore J. McGowan, November 12th, 1567.
Description of thc Accompanying Drawing.
Figure l is an axial section of a pump embodying my improvements, in which the Water is discharged from the open end of the cylinder. Fig. 2 is a similar section with the water discharging through a pipe. Fi". 3 exhibits two views of the, valve ofthe pump-chamber.
General Description.
top of the casing C. A cap, D, is secured to `the casing C by suitable bolts, and this cap can be formed either to connect with a discharge-pipe, as at Fig. 2, or with an open spout, as at Fi g. l. With this form of connection one joint or gasket suffices to make a water and air-tight connection between the cylinder A and the cap D, and the cylinder or casing G and the cap D-or, in other words, one gasket makes the joint between the discharge side of the pump and the exterior air, and between the suction side, of the pump and the outer air. In this respect it differs from the device patented by J. H. and T. J. McGowan, November 12th, 1867, the latter requiring separate and independent gaskets or joint-s with separate fastenin gs. The barrel ofthe pump is iitted with the customary bucket E. The valve B is composed of valve-face e, stem e, centrally-bored Wings e, and cross-bar nut el. A leather or gum-washer may also be inserted between the wings and valve-face. The cross-bar nut c iits the screw-threaded stem e and serves to connect all the parts of the valve together when it is in place, the bar preventing the displacement of the valve. A vent-hole, F, of small size is bored through the cylinder A to carry oif the water from above the pump-barrel to avoid freezing'. The pump itself may be incased with anon-conducting substance. The water permitted to escape at vent F passes directly into the suction-pipe and not into the ground, as in other pumps, the vent opening a communication only between the discharge and suction side of the pump. The space between the casing` C and the pump-barrel is at all times filled with Water to prime the pump in starting.
