UNITED STATES PATENT OEEICE.
BENJAMIN J. C. HOWE, OF SYRAGUSE, NEW YORK.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 44,627. dated OCtObeI 11, 1564- To all whom it may concern:
Be it known that I, BENJAMIN J. C. H owE ot Syracuse, in the county of Onondaga, in State of New York, have invented a new and useful Improvementin Double-Acting Pumps and I do declare that the followingis a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.
The object of this invention is to produce a cheaper and more durable article of use and trade, and also to furnish a ready and efficient engine for extinguishing a ire 5 and it consists, first, in a novel construction of a valve within a hollow piston, combined with a hollow piston-rod; and, secondly, in arranging with a hollow piston and piston-rod, substantially as described, an induction-valve that may he opened at option by the descent ofthe piston for the purpose of permitting the escape downward oi' the water in the cylinder when the piston is at rest.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
I construct the pump-barrel in any of the known forms that may be convenient. The
piston and piston-rod are hollow, thus answer, ing the double purpose of conducting-pipe and piston-rod.
In the accompanying drawing, a a is the hollow piston-rod. b b is the piston. c is a valve for closing` the eduction-ports in the hollow piston. induction-ports.
The valve c consists of a cup having openings in its sides and a iiange exteriorI to the upper edge. This ange closes two or more holes in the top of the piston between the piston-rod and the perimeter of the piston, and a center hole in the bottom of the piston is closed by the bottom of the cup, the water iiowing through the openings in the sides ot' the cup from the lower portl and passing directly over Jthe cup and into the hollow pistonrod from the upper ports. 1t will be noticed that by the descent ot' the piston the valve o is brought in contact with the heel ot' the valve d, thereby opening both valves and allowing the water to escape from the pump.
',Io permit the water contained in the pipe and cylinder to escape to prevent freezing, the piston should be pressed down upon the heel of the valve d.
What I claim isd e are valves for closing the l. The construction and operation of the valve c within a hollowl piston, as shown and described.
2. The extension of the valve ci, in combination with the piston b b and valve c, substantially as shown and described.
BENJAMIN J. C. HOVE.
