Application filed February 4,1901. Serial No. 45,861. (No model.)
To all whom it may concern:
Be it known that 1, JOHN XV. LYON, a resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Self-Closing Faucets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to the class of selfclosing faucets in which the closing of the valve is effected by the pressure of the water in the supply-pipe. It is fully described and illustrated in this specification and the annexed drawings.
Figure 1 represents a vertical section of the outer casing of the faucet and the valve and other moving parts, with the valve closed. Fig. 2 is an enlarged vertical section of valve and moving parts in the lower part of the faucet, as shown in Fig. 1, with the valve open. Fig. 3 is a perspective view of the cylinder that carries the valve separate. Figs. 4: to 7 represent minor parts of the faucet, as will be hereinafter described.
The object of the invention is to provide a faucet that will be closed when allowed to by the pressure of the water in the supply-pipe without any noise and that will not require anypacking to keep it from leaking when in operation or when closed. The following is a description of its construction and mode of operation:
A represents the globe or upper chamber of the faucet, with the delivery-spout C made fast in one side of it.
B is a lower chamber, to the top of which the chamber A is attached by a projection S on its lower side, that screws into the top of the chamber 13 at y.
G is a cylinder (see Fig. 3) that is inclosed in the lower chamber B and which is held by the arms a a and a collar 1" atthe upper ends of the arms a, that screws onto the lower end of the projection S. (See Fig. A valveseat (Z is made on the end of the projection S around the passage J, which connects the two chambers A and B. A valve 7; is held on the upper end of the stem a and is arranged to shut tightly on the seat d above it.
The valve-stem 72, with the valve on it, is shown separately in Fig. i, of which Fig. 5 is a top view. A piston V (seen in Fig. 6, of which Fig. 7 is an end View) is fitted to slide closely in the cylinder G, and the stem of the valve is fitted to slide in the hole in the upper end of the cylinder with suiiicient space around it to allow the water under pressure to pass slowly into and out of the chamber h, made between the upper end of the cylinder G and the piston.
The piston Vand the valve-stem n are made separate to facilitate the placing of them in the cylinder Gr, which is done by putting the stem 11, Fig. 4, down through the hole min the cylinder G, Fig. 3, and then pushing the piston V up into the lower end of the cylinder on the small part of the stem n, Fig. 4, and screwing the nut t on the lower end of the stem.
The pressure of the water in the chamber B, which is equal to that in the supply-pipe H, will press the piston and the valve 7011p against the seat cl. To open the valve, a stem N is inserted in the top of the upper chamber A, (see Fig. 1,) that extends down and rests on the valve 7r. This stein Nis fitted to slide closely in a tube P, which is screwed into the top of the chamber and extends down inside.
The stem N is made small and tapering at its lower end to interfere as little as possible with the passage of the water from the valve, and a shoulder g is made on it to meet the lower end of the tube P, the shoulder having a recess in its top to hold water to form a cushion to prevent its making a noise when it strikes the end of the tube in the closing of the valve. A knob E is attached to the upper end of the stem to press it down by.
To operate the faucet, the stern N is pressed down by the knob E and the valve is pushed down from its seat d, which allows the water in the lower chamber B to flow in between the arms Ct at and through the open valve and passage J to the upper chamber A and out through the spout C. When the pressure is removed from the knob E, the pres sure of the water in the lower chamber B would instantly close the valve 70 again; but
this sudden closing, which causes a disagreeable noise and the effects of a water-hammer, is prevented by a water-cushion in the little chamber h in the upper end of the cylinder G, which fills with water through the hole m (see Fig. 2) around the piston when the valve and piston are pushed down, and this water in the chamber slowly escaping by the annular space around the piston in the hole allows the valve 70 to close gently upon its seat without producing any shock or disagreeable noise.
Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent- 1. In a faucet, the combination of a case, a tube held in the top of said case and projecting down into it, a stem held to slide in said tube to operate a valve, a shoulder made on said stem with a recess in its upper side open to the Water in said case, to form a water-cushion to receive the end of said tube when the valve closes, and a valve, substantially as described.
2. In a faucet, an upper chamber with a valve-seat on its lower end, a tube extending down into said chamber, a stem to operate avalve held to slide in said tube, a shoulder on said stem recessed on its top side to fit over the lower end of said tube, in combination with a cylinder, suspended from said upper chamber, a piston in said cylinder, a valve on the upper end of said piston regulated in its action by the movement of said piston, in said cylinder, substantially as described.
In testimony whereof I have hereunto set my hand this 1st day of February, A. D. 1901.
JOHN WV. LYON.
