UNITEE STATES PATENT GEETGE.
BURRILL PIOKERING AND EDWIN PIOKERING, OF WEST MILTON, AND BARTON APIGKERIN G, OF MONTGOMERY COUNTY, OHIO.
IMPROVEMENT IN PUMP-PlsToNs.
Specification forming part of Letters Patent No. 57,760, dated September 4, 1866.
. JVM
To all whom it may concern.-
Be it known that we, BURRILL PICKERLNG and EDWIN PICKERING, ot' West Milton, Miami county, and BARToN PIGKERING, ofMontgomery county, in the State of Ohio, have invented a new and Improved Piston for Pumps; and we do hereby declare that the following is a full and exact description thereof, refer ence being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of our invention consists, principally, in the manuerof securing the packing and of providing a free passage ot' the Water through the piston.
To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.
Figure l represents a tranverse section of the piston. Fig. 2 represents a top view ofthe piece A. Fig. 3 represents the under surface ot' the piece B. Fig. 4 represents the form of the leather packing'.
A, Fig. 1, represents a cast piece, with the outer surface tapering from the top downward, having arms at the bottom and an orifice for the pump-1 0d O. (Represented at Fig. 2, the dotted lines representing' the taper from the top ot' the arms to the bottom.) From a line with the top of the arms 'the surface inclines outward to the top.
Fig. 3 represent-s the under surface 0i' the cast piece B, the upper surface being a plane on which the leather valve E, Fig. l, rests. There are :live orifices, m'm, made as large as possible for the passage of the water, and with so large openings in the plate, to make it suficiently strong projections n a are formed. (See representation at n, Fig. l.) The piece B has au opening, o, for the pump-rod. The pump-rod has a shoulder at h and a thread cut on the end for the nut D.
The inode ofattaching the packing and valve is described thus: The leather F is placed on the inclined surface ofthe piece A, the pumprod being passed through the valve E and piece B, and through the piece A, and then the nut being' screwed up, the packingis held iirmly between the two pieces ofthe piston, and the valve is held to its seat by the shoulder of the pump-rod.
Ve are aware that pistons have been 'constructed having a plate with aseries of holes and a leather valve used to close them, and with a lower pla-te to hold a packing of such forln that the packingis held between the parallel surfaces.
What we claim as our invention, and desire to secure by Letters Patent, is-
l. The vertical part of the packing-piece A, having an inclined surface, as represented, for the purpose of holding the `iiaring packing F, when combined with the rod O and valve seat B, substantially as described and :repre-` sented.
2. The arrangement of the pieces A B, packing F, valve E, and pump-rod C, substantially as described.
