Description

@gleiten 'tutes 'si-ut @Hire ERAsTUs BLAKESL'EE, or PLYMOUTH, inn JoHN s. HUNTER., or HART- FORD,r GONNECTCUT.
Leim Panni N0. 65,994, ma June 25, 1867,
IMPROVEMET IN WATER-METERS.'
TO ALL WHOM iT MAY CQNGERN: l
- Be it known that we, ERASTUS BLAKEsLnn of Plymouth, in the county of Litchfield, State of Connecticut, and JOHN S. HUNTER, of vlrlartfordrin the county of Hart-ford, and State of Connecticut, have invented a new improvement in Waterdleteyand we do hereby declare the following, when takenfin connection with the accompanying drawings, and the letters of reference marked thereon, to he a full, clear, and exact description of thesame, and which said drawings constitute partl of this specification, `and represent, in
Figure l, a vertical central section, showing the valve in position, admitting the water to one side and discharging it from the other; and in t Figure 2 a like' section,'the valve changed to reverse the inlet in the discharge of the water.
This invention is designed with special reference to the measuring of running fluids, but is applicable to other uses, and consists in the peculiar construction of the valve and. its mode of operation.
To lenable lothers skilled in the art to construct and use our improvement, we will proceed to describe the saine, asillustrated in the accompanying drawings. p v
A and B are the two heads ofa cylinder; C, a piston-rod, passing centrally through the said cylinder, one endfsupported by a stuflug-hox or guide, D, the other in a guide, E, arranged in the valve-chamber F, which said chamber opens into the said cylinder. The cylinder may be arranged for a piston upon. the rod C, or for a diaphragm, asY in' lthe drawing. The diaphragm', denoted .by the heavy black line G, is fitted between the heads of the cylinder and attached to the rod Chaud secured by pla-tes H H. I isthe valve, arranged with passages a, c, and ci, and is operated by a weighted lever, 'c, which has its fulcrum at b. The upper end of the lever is operated by the rod C, which is formediwith a slot,f, so that, as the rod is moved from the position in iig. 1 to that in `fig. 2, thc lever is raised past the perpendicular, hy one end of the slot coming in contact with the lever, and, when scraised, its weight is suiiicient to cause it to fall to the position in fig. 2, and i'n its fall the lower end of the lever comes directly in contact with the valve I, and so causes the valve to move from its position in to that denoted in fig. 2, and upon the return of the rod, the weighted lever is in like manner carried back to its first position, and with it the valve also. L is the inlet, and the outlet, each communi` eating, in rany convenient manner, with its respective feed and discharge pipes; z' and Z are the two outletA ports, and n the inlet port; m is' a. channel, to form a passage from the valver to the opposite side of the dinphragm.- The case which encloses the chamber F, as well as the cylinder itself, may be of any convenient form of construction. -This completes the constructionof my invention; its operation is as follows:
In the two views the rod and diaphragm are representedias upon the turning point, after the position of the valve has been changedthe inilowing water represented hy blue arrows, and the outdowing by red arrows. VThe cylinder-front of the piston, in iig. 1, isfsupposed to be lled with water; at the ,sume time more water is flowing into thechamher F, hack of the piston, through the port ln and opening a of the valve, which creates a pressure upon that side of the diaphragm, forcing the diaphragm forward, and consequently forcing the waterthrough the passage m, and through the passage 0l .in the valve, through the port l, into'the discharge pipe. This continues until, by the movement of the rodthe weighted 'lever c hasbeen turned so far over that, by its own gravitation, it will fall into the position denoted in g. 2, carrying with it the valve I, and reversing the position of the openings. At this time the piston or diaphragm 4has completed its stroke, and arrived at the position denoted in iig. 2. The water now lows in through the port n and passage c of the valve, and passage m, to the opposite side of the piston, by the force of which the piston is returned, andthe water previously admitted tothe other side of the piston'now flows through the opening a of the valve, and the port z', and
.thence to the discharge pipe, and so continues until the movement of the rod C has carried'the lever c over so that, by its own gravitation, it falls to theV position denoted in g. 1, and in its fall-reverses the valve to the position also denoted in iig. 1. To regulate the amount of water passing through the meter, a counter can be attached, at any convenientpoint, in the usual manner. We prefer the diaphragm as shown and described for operating the rod C, yet it will be evident that a solid piston, working in a cylinder, and fixed to the rod C, would perform the same oflice', but with more friction and at greater cost of construction.
Having thus fully described our invention, what We-olnim as new and useful, and desire to secure by Letters Patent, is-
1. The valve I, having the opening a and passages d and e, arranged in relation te the ports in the valveseat so as to operate substantially in the manner described. v
2. In combinntion with the above we claim the Weighted 'lever k, constructed so :is by its movement to reverse the flow of writer, substantially as herein s etforth.
3. In combination with the above We claim the diaphragm or piston, arranged snbstentiaiy in the manner described.

JOHN S. HUNTER. Witnesses:
