1 Claim.

This invention relates to faucets suitable for drawing beer or other carbonated beverages, of the general pop valve type, and the objects of this invention are to provide improvements in such type of faucets whereby construction is simple and inexpensive, appearance is pleasing, operation is certain, life in service is increased, and servicing is both minimized and facilitated;

More particularly objects are to provide an improved valve structure and arrangement whereby it is mounted and improved actuating means for the valve.

The exact nature of this invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing, in which Fig. 1 is a side elevation of a mounted faucet embodying the invention with parts broken away as in typical section to show details of construction, the valve parts appearing in closed position; Fig. 2 is a view corresponding to Fig. 1 but showing the valve parts in open position; Fig. 3 is a view in elevation taken from the far side Fig. 1; and Fig. 4 is a sectional detail of valve actuating parts taken as in the plane of line 44, Fig. 1.

With reference now to the drawing, the faucet comprises a body generally indicated at I, having a cylindrical chamber a, an outlet passage b preferably aligned with the chamber, and leading from the lower chamber end, the valve body having an inlet passage c leading laterally to the chamber. A removable closure 2 is provided at the upper end of the chamber a opposite the outlet passage b. A valve generally indicated at 3 is provided within the chamber a.

with a head part to control the mouth b of the outlet passage b.

More particularly this valve has a metallic body including a stem part 311, a threaded spindle part 3!) aligned with the stem part and a flange part 30 between its stem and spindle parts. A sealing member 3d of rubber or other suitable material is turned onto the spindle part 31) against the flange 30 to seat against and thereby seal the mouth I) of the outlet passage b.

It will be noted that the valve port 12' is ofiset below the inlet 0 and when the valve is open the beer or other beverage strikes the side of the valve member 3 and flows smoothly around the annular space between the valve and the casing l and so down to the port b around the curved lower end of the member 3. It will be noted by those skilled in this art that the member 3 is like the usual; Fuller ball, a well-known commercial article of wide distribution, and readily available when renewal is necessary. This Fuller ball provides an upper portion almost cylindrical but slightly frustro-conical and tapering toward the substantially hemispherical bottom end. It resultsfrom this arrangement that a carbonated beverage such as beer flows more smoothly through the valve than in any prior faucet known to me. 10

Means are provided for maintaining the valve in suitableseating alignment. For this purpose the closure 2 is provided with a recess 2a receiving the valve stem 3a, which latter is provided with a flat portion appearing at, its right in the drawing for venting the recess cavity at the end of the valve stem. To better maintain the valve in its aligned disposition, the closure 2 is provided with a nipple 2b extending into the cavity a to a location adjacent the valve flange 30 when the valve is in open position. To yieldably urge the valve to closed position, a helical spring 4 is positioned about the nipple 2b to bear against the valve flange 30.

To cause opening of the valve, the valve body I is provided with a recess d disposed transversely to and communicating with the outlet passage b, the recess being closed at one end and having at its other end or mouth a packing nut 5. A generally cylindrical shank member 6 is provided having a nose part 60. deformed as indicated, seating in the inner end of the recess, which is preferably of lessened diameter as indicated, the shank member having a head part 6b received by the packing nut 5 and here shown as extending outwardly therebeyond, and intermediate the nose part 60. and head part 6b the shank member has a deformation such as the flange 60 which may bear in the recess d.

Packing I is arranged about the shank member between the nut 5 and the flange 60. It will be obvious that by the described arrangement the shank member 6 is both retained and sealed in its recess d, is removable therefrom by removal of the nut 5, may have rotational adjustment in the recess, and has lateral bearing both at the end of its nose part 6a and in the sealing I and also the parts being suitably proportioned for the purpose, at the flange part 60 and in the nut 5. A cam arm 8 is mounted on the nose part 60. of the shank member, extends from the recess d into the outlet passage b and is suitably proportioned and arranged to engage the end of the valve spindle 31).

Handle means 9 are mounted on the end of the shank 6 for controlling the latter to control the valve. For the purpose as here shown, the projecting head part 6b of the shank member is squared to fit the square opening in the handle 9 and to provide a shoulder indicated in Fig. 4, by which the handle clears the packing nut 5. The handle is secured upon the shank member by a nut Ill threaded into the end of the latter. Preferably cooperative stop members Illa and III) are provided on the handle and valve body respectively as indicated in Fig. 3, to suitably limit the motion of the handle to a range between the positions indicated in Figs. 1 and 2 wherein the valve is closed and opened respectively.

The faucet may be mounted as indicated in Fig. 1, upon a vertical Wall member A of the cooler or the like as by a. long nipple l2 and suitable fittings indicated, all as is known and. standard practice in the art.

It will be noted that although the seal of the valve is effected by the sealing member 3d, actuation of the valve by the cam arm 8 is accomplished'by the metal to metal bearing of the arm upon the valve spindle 3b.

The aligning bearing between the valve stem 3a and the closure 2 is long so that alignment is positive and accurate and the aligning'bearing has long life. The spring 4 has good length relative to its motion so that its life is long. The spring is positively positioned against eccentric effect upon the valve. Yet the parts are exceedingly compactly arranged so that when the valve is open'flo-w is free through a relatively nondevious passage.

For cleaning, removal of the closure 2 permits easy removal of thecomplete valve assembly, and when a new sea-ling member 3d is ultimately necessary, its replacement of the old one is easily accomplished.

What I claim is: i

In a cam-type valve, a body having a substantially cylindrical cavity and having a portion forming a valve seat and having inlet and outlet said stem forming a substantially uninterrupted smooth substantially hemispherical surface to facilitate fluid flow past said valve, the upper end of said sealing material being substantially cylindrical and of less diameter than said cavity, means engaging the other end of said stem to guide it to a predetermined valve-seating position, and control means for said valve comprising a shank member oscillatably mounted in said body, a cam arm rigid on said shank member and movable about said shank member as an axis and having a, bent end adapted to engage said valve stem, the end of said arm having an area of contact with said stem no greater'than the area of said one end of said stem, and the positioning of said shank member and said one end of said stem being so arranged that the end of said cam arm contacts said one end of said stem in both open and closed positions of said valve so as-toavoid Wearing of said sealing member, and said'stem when lifted raises the cylindrical portion of said sealing member to a point opposite said inlet passage.
