WATER- METER.

SPECIFICATION forming part of Letters Patent No. 237,677, dated February 15, 1881.

Application filed July 1, 1880.

T 0 all? whom it may concern.-

Be it known that I, JAMES B. CURRY, of the city of Louisville, in the county of J efferson and State of Kentucky, have invented a certain new and useful Im provement in Meters for Measuring the Water Delivered to Customers by Water Companies; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,'r,eference being had to the accompanying drawings, formingpart of this specification.

This invention relates to a new and novel improvement in cylinder water-meters, consisting, first, in a cylinder and side pipe, with receiving and discharge openings similar to a steam-engine, connecting with a receivingchest on the side pipe, the faces of which openings are dressed ofi perfectly true and covered with a sliding valve, to which a reciprocating motion is given by the pressure of the water as it enters the different ends of the cylinder alternately, where it is measured by the capacity of the cylinder at each stroke, and the number of gallons registered by means of a device similar to a clock or gas-meter. This machine is operated by the pressure of the water acting upon a detached piston-head in the cylinder, which moves it back and forth, and in so doing it strikes the end of the pistonrods and thereby gives motion to the frame or yoke on the outside, which further transmits motion to an arm working loosely on the receiving-pipe, the upper end of which arm is made somewhat in the form of a quadrant with a flange on the in side, having a long slot through it to admit the end of another lever that works loosely on the receiving-pipe, and to which an adjustable weight is secured for the purpose of overcoming the dead-points in the valvemotion by suddenly turning down after passing the perpendicular point, and in its descent strikes the end of a curved lever behind it and presses it down to a stop-lug on the cylinder. This curved lever is also made to work loosely on the receiving-pipe, and by means of a cograck in the center, and a corresponding rack on the end of the arm that works the valveshaft in the chest, motion is transmitted to opcrate the valve in either direction by the oscillation of the weight, as it turns back and (No model.)

forth by means of the pressure of the water entering the ends of the cylinder alternately, as the head moves from one end to the other and the water passes out.

The object of this my invention is to provide a meter for measuring the water delivered to consumers by. water companies, that will be reliable, durable, and convenient in its operation, and at the same time require but little room to contain it while in use. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l. is a perspective view of the machine, showing its general construction. Fig. 2 is a sectional elevation taken, as indicated, at X X, showing the detached piston-head, receivin g and exhaust openings, and slide-valve mechanism. Fig. 3 is a plan view of the cylinder, showing the side pipe, receiving and discharge openings, and frame on the outside. Fig. 4 is a sectional view taken at Y Y, showing the openings and valve mechanism in the chest. Fig. 5 is a plan view, showing the curved lever that gives motion to the valve and the weight that operates it, with the lugs on which it falls. Fig. 6 is a flat view, showing the lugs, edge of the yoke, and arm that operates the weight.

Similar letters refer to similar parts throughout the several views.

This my invention will be more fully illustratedin detail in the drawings, in whichA repthe required size, and bored out on the inside perfectly true, similartoasteam-cylinder. B is the side pipe, which is permanently connected with the cylinder. 0 O are the openings connecting with the cylinder. D is the receiving and E the discharge openings. F is the valve-chest, and G is the slide-valve that covers the openings, and by its reciprocating motion causes the water to enter the ends of the cylinder alternately. H is the arm, and I is the shaft by which it is operated. J is a detached piston-head, working loosely in the cylinder, but packed so as to be water-tight. K K are the packing-followers. L is the bolt by which they are closed up. N N are short piston-rods in the ends of the cylinder, connecting with the frame 0 on the outside, by which motion is given to arm P, which works resents the cylinder, which is made of metal, of v loosely on the receiving-pipe, and by which mo tion is further transmitted to operate thewei ght Q by the quadrant-shaped head S, which has a flange on the inside, with a slot-opening sufficiently long to admit the lever B, which also works loosely on the receiving-pipe, and to which the adjustable weight Q, is secured, and by which motion is given to curved lever T by catching the projections u a 0n the side, in its descent downward, until it rests on lugs U U. At each turn of the weight, and by means of a small cog-rack \V, in the center of lever T, and a corresponding rack on the end of arm A, motion is given to the shaft I and arm H to operate the valve G in the chest F.

Therefore, having thus fully described the nature and object of my invention, its operation is simply that of connecting the machine with the water-pipes, and by means of the pressure the water will enter the cylinder and press the movable head up against the end of the piston-rods connected with the sliding frame on the outside, and thereby transmit motion to the several devices that operate the slide valve in the chest, causing it to move back and forth, and thereby permit the water to enter the ends of the cylinder alternately, and when full pass out, similar to the escape of steam in a steam-engine.

1 am aware that some parts of this machine are made similar to those of a steam-engine, but greatly outof proportion. Therefore I do not claim such combination of parts, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent in a meter for .measurin g water, is-

1. In a water-meter, the combination, with cylinder A, side pipe, B, openings 0 E D, and chest I", of the detached piston-head J, substantially as herein described.

2. In a water-meter, the combination, with cylinder A, side pipe, B, chest F, and detached piston-head J, of the disconnected piston-rods NN, frame 0, arm I and slotted quadrant S, for operating the weight Q, substantially as herein described.

3. In combination with the rods N N, frame 0, arm I, and slotted quadrant S, the curved lever T, cog-rack \V, arm A, shaft I, and arm H, for operating the slidevalve G, substantially as herein described, and for the purpose set forth.
