TAPPING DEVICE.

SPECFICATION forming part of Letters Patent N o. 670,229, dated March 19, 1901.

Application filed July 21,1900. Serial No. 24,418. (No model.)

To @ZZ whom, t may conceive,.-

Beit known that I, CONRAD HAMMER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Tapping Devices, of which the following is a specification.

My invention relates to an improved tapting device principally adapted for barrels or kegs containing beer, ale, or other beverages; and the main object of the invention is to arrange the vent-tube upon a separate part, which will not rotate to wind the rubber or other tubing attached to the vent around the device, and thus necessitate the detachment of the tubing when the tapping device is screwed into a keg or barrel.

It also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Y I Figure 1 is a side elevation of my improved tapping device. Fig. 2 is a central longitudinal section on line a d, Fig. 3. Fig. 3 is a top plan View. Fig. 4 is a vertical central longitudinal section through the vent-tube. Fig. 5 is a detached top plan view of the rubber valve part. Fig. 6 is a section on line o b, Fig. 5.

In referring to the drawings for the details of construction like numerals designate like parts.

A bushing` 1,of any suitable metal,is screwed into an opening in a suitable portion of a keg or barrel. This bushing is provided with a top flange or shoulder 2 and a central' opening, the upper portion 3 of which is screwthneaded and extends from the top downward to about midway the bushing and merges in an intermediate smooth-surfaced portion 4, which in turn enlarges into an annular groove 5. The groove has a horizontal top wall extending at substantially a right angle to the intermediate opening and a diagonal downwardly and inwardly extending lower Wall, which terminates in the bottom portion 6 of the central opening. The bottom portion 6 is formed slightly larger in circumference than the intermediate portion 4, so that the top wall of the groove will form a shoulder or stop for a cork or bung, seated in the bottom portion to prevent its withdrawaloutwardly.

The tapping device consists of an upper memberor part 7, a lower member or part 8, and a vent-supporting member orpart 9, which is litted upon a reduced portion of the lower member or part. The upper member 7 has a central opening 10, an exterior screw-threaded portion 11, and a pair of turning handles 12. The lower member 8 has an enlarged upper screw-threaded opening 13, into which the screw-threadedportion 11 of the upper mem beris screwed,a reduced portion let, having a reduced central opening 15, and a screw-threaded end 16, which screws into the screw-threaded portion'3 of the bushing, and one or more transverse openings 17. The vent-supporting member 9 i's tubular in form and has a transversely-extending interiorlyscrew-threaded tubular portion 18, into which the vent-tube 19 screws. The vent-tube is provided with a serrated outer end 20, toreceive the end of rubber or other tubing, and an annular groove 21 near itsinuereud, into which the inwardly-extending flange 22 of a flexible rubber valve part 23 is detachably sprung. This rubber valve part 23 is formed substantially as shown in Figs. 5 and 6, having a flat extension 24, provided with an elongated opening 25 and a valve-chamber 26, and is fitted upon the inner end of the vent-tube, so as to act as a one-way valve. The opening in the vent-supporting member is sufficiently larger than the reduced portion of the lower member to leave an air-conducting space 28 between the exterior of the lower memberand the interior of the vent-supporting member. The vent-supporting member is also provided with an annular groove 29, which registers with the vent-valve 23 and forms an enlarged air-conductingchamber. The air-conducting space 28 extends nearly the entire length ot' the vent-supporting member and is closed at ing and the lower edge of the vent-supporting member. A hollow circular ring 35, of rubber or other suitable material, is interposed between the lower edge of the upper member and the bottom wallof the enlarged screw-threaded opening in the lower member. The lower member is also provided with a pair of lateral projections or turning handles 36. The upper member has an inwardly-extending flange 14a at its lower end, which is provided with a reduced central opening l5 and forms an annular compressingshoulder for the hollow circular ring 35. (See Fig. 2.)

The operation of the device is as follows: The bushing l being properly screwed into an opening in a keg or barrel, the lower end of the lower member of the tapping device is screwed into the opening in the bushing. The vent-supporting member remains stationary while the lower member is rotated nearly into place, thereby preventing the winding of the hose or exible tubing connected to the venttube around the tapping device. The tap is now inserted in the opening in the tapping device, the upper member is screwed downward sufficiently to contract the ring 35 around the tap, and the tap is driven in, forcing the cork or bung into the keg or barrel.

I claim as my inventionl. A tapping device comprising a lower member adapted to screw into a keg or barrel, an upper member screwing into the upper end of the lower member and a vent-supporting member loosely mounted on the lower member, and adapted to remain stationary when the lower member is screwed into the keg or barrel, and to be tightly secured in place when the tapping device is screwed firmly in the keg or barrel.

2. A tapping device comprising a tubular lower member having a screw-threaded lower end adapted to screwintoa keg or barrel, an enlarged internally-screW-threaded upper end and an intermediate reduced portion, atubular upper member screwing in the interior screw-threaded upper end of the lower member, and a tubular vent-supporting member of slightly-larger interior circumference than the intermediate reduced portion and fitted upon said reduced portion, substantially as Set forth.

3. A tapping device comprising a tubular main memberadapted lo screw into a keg or barrel, and having an enlarged upper portion and a reduced portion and a tubular ventsupporting member of slightly-larger circumference than the reduced portion tted upon said reduced portion.

4. A tapping device comprising a tubular main member adapted to screw into a keg or barrel, and having an enlarged upper portion and a reduced portion, a tubular vent-supporting member of slightly-larger circumference than the reduced portion fitted upon said reduced portion, and packing-rings between the upper end of the vent-supporting member and the enlarged upper portion of the main member and the lower end of the vent-supporting member and the keg or barrel, substantially as set forth.
