UNITED STATES PATENT OFFICE.
MATTHEW HOGAN, OF HARTFORD, CONNECTICUT.
WATER-COCK.
SPECIFICATION forming part of Letters Patent No. 275,487, datedApril 10, 1883.
' Application filed December 4, 1882. (No model.)
To all whom it may concern:
Be it known that I, MATTHEW HOGAN, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful [m provements in Water-Cocks, of which the following is a description, reference being had to the accompanying drawings, where Figure 1 is a view in central vertical section ofa water-cock embodying my improvements. Fig. 2 is a detail sectional view, on enlarged scale, of an old form of packing. Fig. 3 is a detail sectional view, on enlarged scale, of my improved form of packing. Fig. 4 is a top view of the device shown in Fig. 1.
My invention relates to the class of watercocks in which balanced valves are used and it consists in the improved combination of parts for operating the valve, and in the peculiar devices for packing the valve.
In the accompanying drawings, the letter (1- denotes the body of the cock, or valve-body; b, the inlet-passagein the body; 0, the outletpassage; d, the valve-seat; c, a disk-valve secured by stem 6 to the plungerf; g, a cap secured to the body a by screw-thread or by flanges bolted together; h, a packing for the disk-valve; t, a diaphragm packing of flexible or elastic material as india-rubber or the like held at its outer edge between the body and the cap. This diaphragm may be a plain disk; but the corrugated form, as shown, is preferred, the bottom of the plunger being shaped to conform to it in general outline.
The lever It has, arms ll, by which it is pivoted to the valve-body or cap at points on the side in line with the center of the plunger, the latter and the stem 9 of the cap being mortised for the passage of the arm 7c of the lever. I The pin mpasses through the plunger and the cam-slot k in the arm k of the lever, and as the outer end of the lever is depressed the plunger and attached valve are lifted, opening the valve; the reverse motion closes it. The downward pressure of thewater within the cock upon the valve-disk is opposed by the upward pressure against the bottom of the plunger; and by making these opposing surfaces substantially equal in area the bal anced-valve feature of my (leviceis secured. A plane passing through the axis of the disk and plunger and of the pin m passes also through the pivots of the lever, whatever its position in opening or closing the valve, and this arrangement prevents chattering of the valve and leakage from the sudden closing of a cock on a branch near the cook a.
In the form of packing shown in Fig. 2 the bending caused by working the valve comes sharp against the edge of the cap and tends to crack the diaphragm after short use. This defect is completely remedied by using the corrugated form shown in Fig. 3. A cup-shaped form also possesses many advantages.
I claim as my invention-- 1. The combination of a valve-body, a reciprocating plunger, a lever pivoted thereto, and having an eccentric cam-slot traversed by a fixed pin or pivot, the axes of the pivots being at all times in the line of the axis of the plunger, all substantially as described.
2. In a water-cock, a balanced valve, 0, in combination with the valve-body a, plunger f, and corrugated elastic packing i, all substantially as described.
3. In a water-cock having a balanced valve, a corrugated disk-shaped elastic packing, all substantially as described.
