Description:

The object of this invention is to provide an improved construction of faucet or similar device of the reciprocable piston type in which the casing is provided with a chamber around the 6 casing in the region where the piston is in fluidpassage closing position whereby the latter member can, if desired, be made as one head and the pressure thereon equalized. A further object of the invention is to provide an improved construction of such piston valve that it can be compressed by turning the stem as the body thereof becomes worn or to stop leaks if they occur. Other objects will appear from the disclosure herein.

The invention is embodied in the preferred examples herein shown and described, the features of novelty being pointed out in the claims.

In the accompanying drawingFigure 1 is a central vertical section with parts in full of a faucet according to the invention.

Fig. 2 is a horizontal section on the line II-II Fig. 1.

Fig. 3 is a detail view of the piston stem employed in Fig 1.

Fig. 4 is a vertical section like Fig. 1 illustrating a modification of the means for carrying the piston and whereby the piston can be adjusted for compression or relaxation.

Referring first to the views Figs. 1-3, the character 10 designates the casing which has an intake I and a discharge 12. In the cylindrical wall of the case above the discharge is formed an annular projection defining an annular passage 13, said passage having an inlet 14 to which leads a passage 15 so that water or other fluid flowing into the inlet must pass through the passage 14 to the exit at the discharge 12.

It will be observed that the lower end of the cylindrical casing is subtended by a wall 15a and that the passage 15 is formed by an added shell 15b cooperating with said subtending portion and a side of the lower end of the casing.

The character 16 designates the piston which is of cylindrical form to fit in the cylindrical chamber or bore of the casing 10. Said piston is mounted on the lower end of a stem I1 (Fig. 3) the latter consisting of two parts of different diameters with a shoulder 18 at the junction. The lower ends of the portions of the stem are each threaded to receive nuts 19 and 20. The packing-23 or body of the piston which, in the present instance, is of elastic material, such as rubber, is mounted on the stem portion between two washers 21 and 22 with the nuts 19 and 20 press65 ing against them. If desired the body of the piston can be made in two parts with a metal washer 24 between them.

The upper end of the casing 10 is provided with a screw cap 25 that can be removed at will. Said cap is centrally perforated for the a extension therethrough of the upper end of the stem I7.

The stem 17 is shown as provided with means for reciprocating the piston consisting of a hand lever 26, hollow at its lower side, pivotally and removably connected at 27 with the stem and fulcrumed at 28 to one end of a link 29 that, in turn, is pivotally connected at 30 between ears fixedly projecting from the casing 10. By sufficiently elevating the handled end of the lever 26 from the position shown in said Fig. 1 the body of the piston can be moved upward to permit flow of fluid from the inlet 11 to the outlet 12, and in this flow it will be noted, that the fluid passes upward to the opening 14 and thence downward to the outlet 12 which can continue in an ordinary basin spigot, as shown. When the piston is returned to the down position shown in Fig. 1, the pressure of the fluid extends entirely around the body of the piston equalizing the pressure and therefore normally permitting easy movement of the piston.

By unscrewing the cap 25 and elevating the piston so that the nut 19 is exposed a little above the upper end of the casing a wrench can be applied to the nut 19 to expand the washer 22 on the packing and therefore stop a leak; or if the piston be so tight as to render the operation of the piston difficult the wrench can be applied to said nut 19 to relax the expanded condition. In either of these adjustments the pivot member 27 and handle 26 prevent the stem 25 from turning when the wrench is applied.

The two adjustments described in the foregoing paragraph can also be effected by turning the stem 17, while in lowered or closing position, in the proper direction the nut 20 being held from turning by a wall or walls 32 fixed at the bottom of the piston chamber, said wall contacting parallelly with a facet of the nut 20. In Fig. 4 there is shown a piston of improved construction that can be adjusted for the purposes set forth in the two foregoing paragraphs.

In this view the casing part is the same as in Fig. 1, and the piston consists of a body member 40 of cylindrical form and of such material as before described having an axial perforation, the ends of which are conical sockets. The said body member is supported by a screw bolt 41 extended upward through perforated metallic expander members 42 and 43 fitting in the aforesaid conical sockets, and metallic washers 44 and 45 on opposite ends of the body member. The upper protruding threaded end of the bolt 41 is en0 gaged by the internally threaded lower end of the stem 46 proper while the upper end of said stem is adapted to receive an operating handle 26 such as shown in Fig. 1.

The lower end of the bolt 41 is shown as provided with a frusto-pyramidal head that engages a similar socket at the bottom of the piston chamber of casing 10 when the valve is in closed position to prevent rotation of said bolt. By turning the stem 46 in the proper direction the piston body 40 can be expanded or relaxed by varying the pressure exerted on the upper washer 44 by the lower end of the stem 46, such pressure being communicated to washer 45 by bolt 41 and its head. With this construction a leak can be stopped or difficult recipropation of the piston remedied without cutting off the fluid pressure.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is: 1. A faucet of the reciprocating piston-type including a casing having a cylindrical wall with a lateral outlet port at one end thereof, an annular fluid passage in said wall at one .side of said outlet port communicating with the interior of the casing, a fluid intake to the casing at the opposite side of said outlet port, a passage communicatingly connecting said intake with said annular passage, a wall of said connecting passage constituting the end of said cylindrical wall between said intake and the outlet port, and a piston-type valve in said cylindrical wall movable in one direction to close communication between said lateral outlet port and said annular passage and movable in the opposite direction to open communication between said outlet port and said annular passage and thereby establish fluid communication from the intake to said outlet port.

2. A faucet of the reciprocating piston-type including a casing having a cylindrical wall with a lateral outlet port at one end thereof, an annular fluid passage in said wall at one side of said outlet port communicating with the interior of the casing, an intake to the casing at the opposite side of said outlet port, a passage communicatingly connecting said intake with said annular passage, a wall of said connecting passage constituting the end of said cylindrical wall between said intake and the outlet port, and piston-type valve in said cylindrical wall of resilient material movable in one direction to close communication between said lateral outlet port and said annular passage, and movable in the opposite direction to open communication between said outlet port and said annular passage and thereby establish fluid communication from the intake to said outlet port, said piston-type valve having a two part adjustable stem and compression members thereon, and means whereby said stem may be engaged at one end of one of its parts with the aforesaid wall of said connecting passage and the compression members actuated by turning the other part of said stem.
