JOHN DEMABEST, OF NEWV YORK, N. Y., ASSIGNOR TO THE J. L. MOTT IRON \VORKS, OF SAME PLACE.
PRESSURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 3117416, dated May 12, 1885.
Application filed March 13, 1885.
To aZZ whom it may concern:
Be it known that I, J OHN DEMAREST, of the city, county, and Stateof New York, have invented an Improvement in Pressure-Regula tors, of which the followingis a'speoification.
In many places the pressure of the watersupply is very great, and there is risk of the pipes in the buildings being injured, especially by the ram action or waterham'mer due to the sudden closing of faucets. Pressureregulators have been made which serve to lessen the concussion or water-hammer; but with these the pressure in the distributionpipes within the building accumulates and becomes the same as in the water-supply pipes.
The object of my invention is to entirely prevent the accumulation of pressure in the distributioupipes, and to cause the regulatorvalve to close so gradually that there is no concussion or noise, and hence no injury to the pipes.
In the drawings, Figure 1 is a vertical section of my pressure-regulator, and Fig. 2 is a sectional plan at the line x a".
The regulator is composed of a cylindrical case having a larger diameter at A and a smaller diameter at B and at the bottom end, and opening into the cylinder B of small diameter is the pipe 0, with a raised valve-seat, c, and to this end of the regulator is attached the supply-pipe E by a screwcoupling or otherwise.
At one side of the cylindrical case there is a water-way, F, opening laterally into the cylinder B near the seat 0, and this water-way extends upwardly and unites with the hub G for the coupling of the distribution-pipes. There is a narrow lateral opening, i, from the water-way F into the upper part'of the cylinder A, near the cap K, that is screwed upon the top of the cylinder A.
Within the case is a stem, Z, with a valve, 12, at one end, faced with leather or rubber, and this valve is over the seat 0, and there are also on this stem Z two cup-leather valves, standing in opposite directions, the leather M being the largest and fitting the cylinder A, and the leather N the smallest and fitting the cylinder 13, and there is an opening and lateral escape at t.
(No model.)
The operation of this regulator isthat, the relative sizes of the cup-leathers M N being proportioned to the pressure desiredin the distribution-pipes, the valve will only open the proper distance to supply the proper quantity of water into the distribution-pipes to pass away from the faucet orfaucets at the lower pressure, and so soon as such faucet is closed the valve is shut upon its seat by the smaller pressure of the water in the distribution-pipes acting upon the larger area of the cupleather M and overcoming the pressure upon the smaller area cup-leather and upon the valve a, and causing the descent of such valve upon its seat.
It will be observed that if water leaks past the cup leather and accumulates between them the regulator is rendered useless, because the pressure becomes balanced at opposite sides of the cup-leathers, and they cease to act in closing the valve. To prevent this I employ an escape pipe or opening at if, so that leakage may pass away and the cupleathers be maintained in proper operative condition.
I claim as my invention 1. The combination, with the supply-pipe and valve-seat, of a case having two different sizes of cylinders, cup-leathers of different sizes in such cylinders, a stem connecting the cupleathers, a valve upon the stem, and a water-way connecting the water-supply and distribution pipes and opening into the cylinder above the largest cup-leather, substantially as set forth.
2. The case having the cylinders A and B, of different sizes, the valveseat, the supply and distribution pipes, and the water-way between the parts of the case, in combination with the two cup-leathers, the valve-stem,
valve, and the escape-pipe from the case between the two cup-leathers, substantially as set forth.
Signed by me this 4th day of March, A. D. 1885.
JOHN DEMAREST.
