UNITED STATES PATET EFICE.
LUKEVOHAPMAN, OF COLLINSVILLE, CONNECTICUT, ASSIGNOR TO HIMSELF AND WILLIAM J. WOOD, OF SAME PLACE.
IMPROVEMENT IN ROTARY PUMPS.
Specification forming part of Letters Patent No. 137,055, dated March E5, 187B.
To all whom it may concern:
Be it known that I, LUKE CHAPMAN, of Collinsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Rotary Pumps, applicable as well to rotary motors, meters, and blowers, of which the following is a specification, reference being had to the accompany ing drawing, in whichv Figure l is a side elevation of the whol pump. Fig. 2 is an end elevation of the same with the head removed to show' the interior. Fig. 3 is a side view of one of the rotary plungers. Fig. 4 is an end view of the same.
This invention is a new construction for retaining the cylindrical valves used in their seats.
The letter a indicates the outer shell formed of two intersecting hollow cylinders of equal size. .b b are the heads for the same appropriately fastened on by screws b1 and having bearings and boxes b2 for the plunger-shafts c1, which are made to rotate with equal motion in opposite directions by engaging gears, one of which, c2, is seen. Power may be applied to either shaft. The motion is in the direction indicated by arrows. dis the ingress-pipe; d',
On the shafts c1 are iixed the plungers c, which are exactly alike, each having four parti-circular valve-seats, c2 c2 c3 c3. The valve-seats c2 are different from the valve-seats c3. The latter have a depth and out-line greater than a half circle, so that they hold in the cylindrical valves e, which have to be slipped in endwise 5 the former are less than a half circle, being just deep enough to meet the projecting part of the valves contained in the other plun ger. The plun gers are in constant contact, except at the valve-seats, and these intervals are filled by the valves.
The water is drawn in at the pipe f and carried around, as indicated by the arrows, and ejected through the pipe r1 The plun gers and valves extend entirely across the inside of the pump.
Thus it will be seen that the valves are free to rotate in their seats, and so continually present new wearing-surfaces, and at the same time are firmly held in their seats.
I claim as my invention- A 1. The combination of the cylindrical valve c with the plunger c when the valve is held to the plunger by beinginserted in a valve-seat of a depth and outline somewhat greater than a half circle. a
2. The combination and arrangement of the two revolving plungers c of equal size, having valve-seats of the shapes and relative sizes shown and described, with the cylindrical valves c. v
