IMPROVEMENT IN LIQUID AND GAS-METERS.

TO ALL WIIOM IT MAY CONCERN: v

llc it known that I, JOSHUA MASON, of Paterson, in the county of Passaic, and State of New Jersey,- have invented a new and improved Water and GnsMeter; and that the following description, taken in connection with the accompanying drawings, hereinafterreferred to, forms a full and exact specification of tl1csamc,whcrein I have set forth the nature and principles of my said improvements, by which my invention maybe distinguished from all others of a similar class, together with such parts as I claim and desire to Yhave sceured to me by Letters Patent. i i

This invention relates to a new and improved water und gasmeter,.and consists in a novel construction and :arrangement of parts, as hereinafter fully shown and described, whereby water or gas may b'e measured inthe most accuraternannelyand by a means not liable to get out of repair o'rheeome deranged by use. v In thc accom-V pnnyingrsheetof drawings- Y Figure l is a longitudinal vertical section of my invention, taken in the line :u 9:, iig. 3.

.A represents a cylinder, which may be of any suitable dimensions, and is provided with a plunger,rB, shown clearly in iig. I. The cylinder A has ar. extension or chamber, C, at one end of it,and withinV said extension there is a valve-chamber, D, containing a valve, E, which is a sliding one, and is composed of a rod, a, having` two circular disks or heads, Z o', upon it, and a circular' plate, F, at one end, which plate `is perforated'with holes c to form a communication between the interiorv of the'valve-chamber and the extension or chamber C,"as

. shown clearly in iig. l. The valve-chamberl is open at both ends, and is provided with three ports, d ai d",` l which extend circumferentially around; the interior of the valve-chamber. The port oZ communicates with the i l supply pipe G, the port cl with a water-passage, H, which leads into the reareud of cylinder A, and theport CZ communicates with the discharge pipe'or faucet I.V The plunger B has a forked har, J, attached to onefend of it, at its centre, and to each end of said bar a rod, K, is attached, said rodsbeing parallel with eachother,` and passing loosely through anges or bent ends of plates L L, the main portions of which `are parallel with cach other. `The outer ends o f these platesL L are connected by a piti or pivot-bolt, e, to one end of a. rod, M which passes loosely and longitudinally through the valve E, and has n. head, f, o n its outer end, as shown clearly in iig. 1. The outer ends o f the rods K are provided each with a screw-nut, g, to bear against thc flanges or bent ends of the plates L L, as the plunger I3V reaches the termination of its movement in the direction indicated by arrow I. N is a toothed segment, which is suspended within the cylinder Aand gears into a pinion, O,`one p end of the shaft of which is provided witha crank, h, and the opposite end provided with a crank-wheel, c', the

wrist-pin j of which passes through an arm, 7c, connected to a crank, l, on the inner end of a shaft, l?, the outer end oi" the latter being provided with a pendent arm, Q, having a pawl, R, attached, which works into a ratchet,

in, the -shaft of the latter having an index, n, which works over a graduated dial-plate, o. The shaft P passes` through a smiling-box, p, into the cylinder A, to avoid leakage from the cylinder around said shaft. The crank 7L is connectcdto a spiral spring, S, the upper end of which is fitted on the pin or shaft on which the segment` i N is suspended. The plates L L have a pin, g, passing through them, and this pin passes into a slot, e, `in thc segment N, as shown in iig. 1. When the valve E is in the position shown in`i'ig.1, to wit, the port d between the disk Z and the plate F, the water will pass from the supply pipe G into port CZ, and thence into` the pa/ssagc G, and through the same into the rear end of cylinder A, as indicated by the blue'arrows, forcing the plunger B in the direction indicated by the arrow I. After the plunger has moved a certaindistance in` thisgdirection,

the forked bur J comes in contact with the plates L L, when vthe latter are shoved forward, and consequently l the rod M and thescgment N will be moved as it is connected to theplates L, and the .pinion O turned so that the crank 7i' willdistend or stretch the spring S until the crank 7L passes its centra-'when the springSimmediatcly contracts and suddenly throws the segment N forward, and 'causes a shoulder, a, onqtherod M,`to actunte` i the valve E, and slide or shift it so that' the disks b Il will be in the p osition shown `in red, and the4 n tcrfrbm t com:

the supply pipe G made to act upon theopposite side of the plunger, as indicated by red arrows, and move said plunger in the direction indicated by arrow 2, while tlie'waterin the cylinder at the opposite side of the plunger will be forced back, as indicated by the red arrows through passage H and the port d, and out of the discharge pipe or faucet I. As the plunger B approaches the termination of its movement in the direction indicated by arrow 2, the segment N is drawn back, in consequence ot the rods K K drawing back the plates L L, and the pinion O will beturned in a reverse direction, and the spring S distended until the crank 7L passes its centre, when said spring instantly contracts and suddenly throws the segment N in the direction the plunger is moving, and causes the plates L L to move the rod M in a corresponding direction, so that the head j' will move back the valve E to its original position, so that the water will be cut ,oit in its flow, as indicated by the red arrow, andmade to pass again through the passage H, as before, and move the plunger B' in the direction asv indicated by arrow 1, the wat'erwhieh previously passed into the cylinder, .as indicated by the red arrows, being forced through the extension C, through the perforations @,in plate F, and thence out through the discharge pipe or faucet I, as also indicated by blue arrows. i v i i When the invention is used as a gas-meter the operation is precisely the saine. By referring to tig. 5 it will be seen that the pinion O is connected with its shaft by means of a pin,-ct, the latter being fitted tightly in thelshaft, but passing into a slot, bx, in the hub of the pinion, which Aslot is considerably wider than the pin ax, and admits ofthe pinion having sonic play on its shaft. The object of this is as'ollows: When the plunger B is working the toothed segment N and the pinion O, the latter turns its shaft through the medium of the pin ax, but the instant the crank t passes its centre, the crank-shaft, by means of the spring S, drives the pinion and the rack, and the valve. New, it is necessary, for the accurate working of the-meter, that the changes of' the valve be prompt, und this is effected lay-means of the slottedhub, as it gives the crank h a little leach until the space or slot in the hub of the vpinion isA taken up, which, although Ismall in the hub, is considerable on the crank-pin., and it comes to its work with a little blow, and into a position more favorable'for the action of the spring. By adjusting or turning the nuts g of the rods K K, the latter may be virtually Iengthened or shortened, and consequently the stroke of the plunger B graduated as may be required, and an exact measurement of the water obtained, and any irregularity in the bore of the cylinder compensated for. The barl J, to which the rods K K are attached, is connected to the plunger B by a screw or pin, e".,'to forni a swivel connection, and admit ofthe plunger casually turning'withiu the cylinder without affecting any of the parts attached to it. 'lhe amount )of water discharged is indicated by the pointer or index n on the dial o, which is operated each timethe pawl R is shoved in the direction of arrow 3, which occurs at every alternate movement of I plunger B, or each time said plunger reaches one end of the cylinder. The valve E works in a balanced state, and still is not liable to casual derangement or movement of any kind.

Having thus described my invention, I claim as new7 and desire to secure by Letters Paten t l. The sliding-valve E, composed of the circular disks 6b and the perforated plate F, and ttedwithin the circular chamber D, provided with ports d dj, extending eircumferentially all around the interior of`the chamber, and placed or arranged in relation with the supply and discharge pipes G I, passage H, extensionchamber C, and cylinder A, to operate in the manner substantially Aas and for the purpose set forth.

2. The operating of the valve E `from the plunger B, through the medium 'of the rods K, plates L, rod M, segmentll', pinion O, and spring S, connected with the crank 7c ofthe shaft of the pinion O, all arranged substantially as shown and described. i

3. The combination and arrangement of the rods K, screw-nntp, plates L, rod M, and bar J, as herein described, forthe purpose speciicd i I 4f.` The combination and arrangement of the clutch, consisting of the tixedpin ax in the shaft ofthe pinion O, and the slot bx-in'said pinion, with the crank h, spring S, slotted segment N, and plunger B, as herein described,rfor the purpose specified JOSHUA MASON.
