SLOW-CLOSING FAUCET.
SPECIFICATION formingpart of Letters Patent No. 557,292, dated March 31, 1896.
Application filed March 3 0, 1 8 94.
To all whom it may concern:
Be it known that I, WILLIAM A. TURNER, a citizen of the United States, residing at Worcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Improvement in Slow-Closing Faucets, of which the following is a specification, accompanied by drawings representing a part of the same, and in which- Figure 1 represents a central vertical sectional view of a slow-closing faucet embodying my invention. Fig. 2 represents an enlarged View of the adjusting screw or valve by which the air-passage communicating with the piston -chamber is varied, the cap in which the adjusting screw is held being shown in sectional view. Fig. 3 is a top view of the cap by which the air-valve chamber is closed; and Fig. 4 is a central sectional View of the adj llSlJlIlg-SCIGW, the parts shown in Figs. 2, 3, and 4 being represented on a larger scale than in Fig. 1.
Similar letters refer to similar parts in the different figures.
Referring to the drawings, A denotes a shell forming the body of thefaucet and con taining a waterway or passage B.
C represents an annular valve-seat to receive a Valve-disk C, which is carried upon a valve-stem C and held between the washer C and nut C Upon the lower side of the shellA is a circular opening provided with a screw-thread D to receive a screw-threaded circular cap D, provided on its inner side with a hollow boss D having its axis in alinement with the axis of the annular valve C and forming a bearing for the lower end of the valve-stem C, which is capable of a vertical sliding motion within the hollow boss D Resting upon the end of the circular cap D and bearing against the under side of the washer C is a spiral spring D by which the valve-disk C is held in contact with the annular valve-seat C.
Within the upper portion of the shell is a circular chamber E, communicating at its lower end with the waterway B and having its upper end closed by a cap E, which rests upon a packing E so as to form an air-tight joint with the shell A. The cap E is held in Serial No. 505,761. (No model.)
place by a ring E having an internal screwthread E, by which the ring E is screwed upon the screw-threaded section E of the shell A.
Depending from the under side of the cap ner wail of the chamber E and its inner edge bearing against the hollow boss E, in order to form an air-tight packing for the piston F and prevent the passage of water or air from the waterway B to the air-chamber G, inclosed between the piston F and the cap E.
An ainpassage is made through the cap E communicating with the airchamber G, as shown in Fig. 2 of the drawings. Upon the under side of the cap E is a circular recess closed by a cap H forming a chamber H. Held in the cap E is a screw H having a central hole H extending throughout its length. A head H is formed upon the lower side of the screw, against which a valve-disk H is held by the tension of a light spring H. A hole H in the side of the screw H communicates with the central hole H and a packingring H is placed on the head of the screw and between it and the cap E.
The upper end of the screw H is provided with a slot H to receive a screwdriver, in order to enable the screw to be adjusted within the. cap E". The cap H is provided with a hole H directly beneath the valve-disk H, forming a communication between the chamber H and the air-chamber G. Extending upward from the cap E is a lug I, to which is pivoted a lever I, carrying a friction-roll1 bearing upon the upper end of the piston-rod F. The lower end of the piston-rod F is hollow for a short distance, as at F and incloses the upper end of the valve-stem C ICO which is brought into contact with the pistonrod when the valve-disk C is raised against the valve-seat, as shown in Fig. 1.
The operation of the faucet is as follows: The piston-rod F is depressed by the angular movement of the lever-handle I, pushing the valve-stem O downward against the tension of the spiral spring D thereby carrying the valve-disk off the valve-seat C and opening the faucet. As the piston F is moved downward in the operation of opening the faucet, a partial vacuum is formed in the air-chamber G, causing air to pass through the central hole H in the screw H with sufficient pressure to carry the valve-disk 1-1 out of contact with the screw-head H compressing the spring H, which possesses only sufficient tension to balance the weight of the valvedisk and hold it normally in contact with the screw-head. The air entering the valvechamber II passes through the hole H into the air-chamber G.
\Vhen the lever-handle I is released, the tension of the spiral spring D is exerted to raise the valve-stem and piston F against the pressure of the air, which becomes compressed in the air-chamber G, and the valve-disk H is lifted into contact with the screw-head H by the tension of the spring H thereby closing the lower end of the central hole H and allowing the air to escape from the air-chamber G only through the small side hole H As the area of the hole 11 is restricted, the upward movement of the valve-stem will be retarded by the pressure of the air in the airchamber G, causing the faucet to be closed slowly and with a speed which can be varied by the adjustment of the screw H in the cap E, so as to vary the area of the air-passage through the hole H What I claim as my invention, and desire to secure by Letters Patent, is
1. In a slow-closing faucet, the combination of a shell A, provided with a waterway, or passage, a valve-disk by which said waterway is closed, a spring applied to close said valve, a piston-rod sliding in a hollow sleeve, a piston carried by said piston-rod and inclosed in a chamber, an annular packing-rin g by which said piston is packed against the sides of the chamber and said hollow sleeve and a restricted air-passage communicating with the piston-chamber, substantially as described.
2. In a slow-closing faucet, the combination with the shell A, provided with a waterway, or passage, and a reciprocating valvedisk by which said waterway, or passage, is closed, of a piston-chamber E closed at one end by a cap E, a hollow sleeve E depending from said cap, a piston-rod F in contact with the stem of said valve-disk, a piston F, an annular packingring F arranged to bear against the side of the piston-chamber and said hollow sleeve, a restricted air-passage in said cap E, and an adjusting-screw H held in said cap, by which said air-passage is varied, substantially as described.
3. In a slow-closing faucet, the combination of a reciprocating valve by which the faucet is closed, a piston inclosed within a piston-chamber and operatively connected with said valve, an adjusting-screw held in the walls of said piston-chamber and provided with a central air-passage extending through said screw and communicating with said piston-chamber and a valve-disk arranged to close said air-passage, said screw having a restricted hole 11 communicating with said piston-chamber and said air-passage, substantially as described.
