Description
M. HOGAN. Water-Cock.
No. 202,653. Patented April 23,1878.
y/IIIIIIIIIIIIIIIJ UNITED STATES PATENT OEEIoE.
MATTHEW HOGAN, OF HARTFORD, CONNECTICUT.
IM PROVEM ENT IN WATER-COCKS.
Specification forming part of Letters Patent No. 202,653, dated April 23, 1878; application filed December 24, 1877.
To all whom it may concern:
Be it known that I, MATTHEW HOGAN, of Hartford, in the county of Hartford and State of Conn ectieut, have invented. certain new anduseful Improvements pertaining to a Water- Oock, of which the following is a specification,
. reference being had to the accompanying draw- Fig. 2 is a view in intermediate water-wayg, out through the exitpipe 0; but there is a water-way (denoted by dotted line h) leading from below the diaphragm to the chamber above the diaphragm. This admits water above the diaphragm, so as to balance the water-pressure, and I will call it the balance-conduit. Thus balanced, it is evident that, otherwise unafiected, the incoming water will not raise the valve d, and the gravity of the valve and the smaller area on top of the diaphragm exposed to pressure (either or both) tend to close the valve.
I will now describe how the valve is opened:
From the chamber above the diaphragm an escape-conduit, z, (denoted by dotted lines,) leads to the exit-pipe 0. Midway of this escape-conduit is located a subsidiary valve, described hereinafter, which, when opened, allows the water above the diaphragm to escape, so thatit can rise and the main valve be opened. When this subsidiary valve is closed the eh amber above the diaphragm again fills with water and the main valve closes. The balanceconduit h is smaller than the escape-conduit, so as not to materially interfere with the operation of the escape-conduit.
It will be seen from the drawings that the balance-conduit and the escape-conduit are the same for a part of their course. This is not essential; they can be entirely distinct.
I will now describe the subsidiary valve: The letter 70 denotes the valve, and k the valve-seat. When the valve is pressed down, as shown in Fig. 2, in order to show the exitconduit as continuous, the water passes freely through. This valve is borne on the rod 1, running to the finger-cap a, which (for the mere purpose of keeping the subsidiary valve closed, it may have any proper spring) contains the closing-spring m, of rubber, kept from setting and from adhering to the valve-rod by the interposed helical spring a.
I will now describe a device for preventing the main valve from hammering when suddenly closed. The valve-rod d is furnished with the disk 0, which fits (not too tightly) into the corresponding disk seat 0. The thickness and relative arrangement of the valve d and this disk are such that this disk will shut into its seat before valve d strikes the valve-seat, the effect of which is to mainly, but not wholly, check the intlowing current before the main valve strikes squarely on its scat, giving as a result the prevention of hammering.
The diaphragm rests on the shoulder p, and is confined or held between this shoulder and the flange 1", which is on the cap a, which screws into the body a. The flange r is 0011- caved or curved, and perforated, to allow the contained water access to the escape-conduit.
The chamber below the diaphragm is denoted by the letter s, the one above the diaphragm by the letter 2.
It will be understood that the cock is opened by pressing on the finger-cap u, and when the pressure is removed the spring underneath closes the subsidiary valve, and consequently the water-cock.
The letter 1* represents a small screw, which is used to make the balance-conduit larger or smaller, as it may be found necessary for the successful working of the valve. This screw pierces into the balance-conduit, and is screwed in to make the conduit smaller, and vice versa.
I claim as my invention- 1. In combination, the chambers s and t, connected by the balance-conduit h, the valve 07, 4. In combination, the diaphragm f, the connected to the diaphragm f, the escape-eonshoulder p on the case a, and the cap a, duit 1', provided with a subsidiary valve, and provided with the eoncaved and perforated the entrance and exit pipes. flange 1".
2. In eombinatiomthe valve-rod I, the rubber MATTHEW HOGAN. spring m, and the interposed helical spring n. Witnesses:
3. In combination, the valve d, disk 0, and WM. E. SIMONDS, disk-seat 0. E0131. RGAYLORD.
