` IMPROVEMENT IN PUMPING-LEVERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern B e it known that I, JOHN S. APPEL, of Kulpsville, ,in the county of Montgomery, and State of Pennsylvania, have invented a new and useful Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had 'to the accompanying drawings, forming part of this specification. l

This invention relates to an improvement in pumps for raising water and other liquids; and

It consists in the arrangement and combination of parts, as hereinafter described.

The drawing represents v a vertical section of the pump, showing the different parts -in their proper positions. g Y

A is a wooden standard, to which the pump is attached.

B B represent the pump-cylinders.

O C are thel piston-rods.

D D represent the pistons or valve-boxes, which are attached to the ends of the rods C C.

E is the foundation-plate, to which the cylinders B are secured.

F F represent the foot-valves in the bottom of the cylinders. These valves, as well as those in the boxes D D, operate on hinges, as seen in the drawing.

. G is a valve-chamber, and

H is a ball-valve therein.

This chamber Gr is screwed on to the cylinders, and the ball-valve has a seat at each end, and plays back and forth from one seat to the other when the pump is operated.

h represents one of the seats.

I is the water-pipe, and the 'water is discharged at J.

K is the air-chamber.

The lrods C C extend up and are attached to the brake-beam L, as seen in the drawing.

On this beam the rods C G are adjustable, so that the length of stroke may be increased or diminished,

The notches marked @between the beam and the levers, allow the loops on the ends of the rods to be changedfrom one to the other.

m represents the levers, which are secured to the v brake-beam by the clips and set-screws n and the loops n', at the centre,.as seen, so that the levers may be readily detached when it is desired to alter the stroke. The rods C C maybe made of metal entirely, or of metal and wood. I prefer to 4introduce a section of wood.

The rods O C are passed through a stationary guide, I), for the purpose of keeping them steady, and where they enter the cylinders they work in, stuing-boxes q -q in the usual manner.

By this arrangement, a constant stream of water is discharged from the pipe I with a velocity proportioned movable levers m, the notched brake-.beam L, and the looped rods C, as herein described for the purpose specified.

Witnesses: JOHN S'. APPEL.
