PATENT Orrrciil HENRY M. WYETH, OF NEWARK, OHIO. A
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 171,905, dated January 4, 1876 5 v application led November 30, 1875.
To all whom it may concern Be it known that I, HENRY M. WYETH, of Newark, in the county of Licking and State of Ohio, have invented a new and Improved Pump and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l is a vertical section Fig. 2, a vertical sectionat right angles to Fig. l.
This invention relates to certain improvey ments in pumps; and it consistsfin the peculiar construction of a double-acting submerged pump, in which two valves are connected by a slide, so Aas to move together on opposite sides of the piston, and operate both the induction and discharge ports.
In the drawing, A represents the pump case or cylinder, which may be of any shape and material 5 and Bis the piston, which fits nicely in the cylinder, and is made imperforate. C C are the head-pieces of the cylinder, which are constructed with induction-ports a a', and inner recesses b b', forming valve-seats. D represents the discharge-pipe, which opens through the discharge-ports c c into the cylinder. E E are the valves, which move in recesses b b and d d', and are connected by a slide, F, so that they both operate together upon opposite sides ot' the piston. The said slide ts accurately in a groove in thecylinder, so that its surface is flush with the inside periphery, and the valves have lateral openings c c', which register alternately with the discharge-ports c c. 4
The operation of the pump as thus described is as follows: When the piston is elevated by its rod the pressure of the water above it, and the suction beneath, cause the valves E E and the slide F to be raised together. This movement closes .induction-port a, and opens discharge-port c, allowing the water above the pistonto escape into the discharge-pipe D. The same movementalso opens the inductionport a', and closes the discharge-port c', allowing the water to enter the cylinder, and follow the piston upon its upwardstroke. When the piston descends the valves descend from the pressure and suction of the water, and
, ports a and c being opened, and a' and c closed,
the water beneath the piston is forced into the discharge-pipe, and a new supply drawn into the cylinder above the piston.
Thus it will be seen that there is always a communication between the cylinder and the discharge-pipe, so that the water from the latter may run back into the cylinder, thus preventing the water from ever freezing i'n the discharge-pipe.
Iam aware of the fact that it is not, broadly, new to connect the valves of a pump, so as to cause them to operate in unison, and I therefore confine my invention tothe particular construction and arrangement of the devices, as shown and described.
Having thus described my invention, what I claim as new is- The improved pump, consisting of the cylinder A, havin g discharge-ports c c and recesses d d connected by a groove, in combination Y with the valves E E', provided with holes e e/ and a connecting-slide, F, the cylinder-heads- G C having induction-ports a a', and recesses b vb', and the piston, substantially as and for the purpose described.
. HENRY M. WYETH.
