ALFRED VON FORMACI-IER, OF NEW YORK, N. Y.

ATTACHMENT FOR BARREL-TAPS.

weaver.

Application filed February 10, 1913.

To all whom it may concern Be it known that I, ALFRED VON FOR.- MACHER, a citizen of the United States of America, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Attachments for Barrel-Taps, of which the following is a specification.

This invention relates to certain improvements in the attachment for barrel-taps for which Michael J. Zwosta and Gottlieb Soehngen have received Letters Patent on February 14, 1911, No. 98 1360, so that the attachment can be operated in a quicker and easier manner by the actuation of a single lever, whereby also the construction of the attachment is considerably simplified; and for this purpose the invention consists of an attachment for barrel-taps which comprises a ringshaped collar which is placed over an elastic packing ring or gasket on the bushing of the tap-hole, upright posts on said collar, a lower cam-ring guided by segmental slots on said posts and provided with a leverhandle, an upper cam-ring also guided on said posts, said cam-rings serving when raised on the posts for holding the packing ring or gasket with increased pressure on the tap-hole for tightly closing it when tapping the barrel.

In the accompanying drawing, Figure 1 is a vertical central section of my improved attachment for barrel-taps, showing it in position on a tap and tap-hole of a barrel, Fig. 2 is a side-elevation, Fig. 3, a planview of the same and Fig. 4c, a perspective view of the lower cam-ring shown as detached from the attachment.

Similar letters of reference indicate corresponding parts throughout the figures of the drawing.

Referring to the drawing, a represents the head of a barrel for beer or other fermented liquids. Into the bushing a of the tap-hole is driven a faucet or tap b of the usual construction, through which a draftpipe is inserted in the usual manner. The bushing a is screwed in the tap-hole of the barrel-head a and closed by a wooden plug a in the usual manner. A rubber or other tube (not shown) is connected with the upper part of the tap b for supplying air or carbonic acid gas under pressure to the interior of the barrel and forcing the contents of the same through the draft-pipe and a Specification of Letters Patent.

suitable connecting pipe to the dischargefgpcet at the bar, where the beer is drawn 0 On the lower portion or shank of the tap b is placed my improved attachment, which is composed of three parts, a ring-shaped collar 0, a lower cam-ring c and an upper cam-ring 0 through which the tapering shank of the barrel-tap is inserted when the same is to be driven into the wooden plug for tapping the barrel. Between the lower portion or collar 0 of the attachment and the upper end of the bushing a and plug a is interposed a ring-shaped elastic packing or gasket 79. The ring-shaped collar 0 is connected by fixed upright and headed posts 9 secured at diametrically-opposite points to the same with perforated ears 0 of the camring 0 so that the latter can move vertically on the posts. The lower cam-ring c is guided (by means of segmental extensions 0 having arc-slots c concentric with the axis of the tap) on said posts 9 when it is shifted on the posts 9 by means of a lever-handle h which extends from the lower cam-ring 0 and is preferably cast integrally therewith. The lower cam-ring c as well as the upper cam-ring c are provided with raised camfaces at their adjacent sides. The lower camring 0 is guided by a circular shoulder 0 at its lower portion in a corresponding recess c" of the collar 0 so as to bring the camface of the lower cam-ring into or out of registering cont-act with the cam-face of the upper cam-ring, as shown respectively in Figs. 1 and 2. The slotted segmental extensions 0 of the cam-ring are guided on the upright posts 9 and preferably made in one integral casting with the lower cam-ring and the lever-handle h of the same. The upper cam-ring 0 is provided at one point of its circumference with a screw-socket s and clamping screw 8 for attaching the camring 0 to the shank of the tap.

Before the tap is driven in the tap-hole, the attachment is placed in position on the tapering shank of the tap. The tap is then driven tightly into the wooden plug a and the cam-ring secured in place by screwing in the set-screw s. The lower cam-ring is then shifted by means of the lever-handle so that the raised portions of the cam faces of the cam-rings are placed one over the other and the collar 0 is pressed tightly on the packing ring and the latter on the taphole and plug. The attachment is thereby held firmly on the tap and head of the barrel until it is empty. The pressure of the attachment on the packing prevents the escape of gas from the barrel in case the plug is split or injured when driving in the tap, so that the beer or other fermented liquid is kept in fresh and good condition.

The attachment can be readily operated by the turning motion imparted to the lever in the direction of the arrow shown in Fig. 3, and be likewise released by the returnmotion of the lever-handle when the cam faces are placed in register with each other, so that the barrel-top and draft-pipe can be removed from the empty barrel and inserted into the tap-hole of another barrel, in connect-ion with the attachment, which is again placed in position on the tap and tap-hole by the action of the cam-rings and lever-handle.

The advantages of my improved attachment for barrel-taps are that one singlelever and one single motion of the lower cam-ring are necessary for accomplishing the tight application of the packing ring to the tap-hole and plug of the bushing, so as to prevent the escape of gas in tapping and after tapping, while the manipulation and construction of the tapping attachment are simplified and rendered more effective and reliable.

I claim:

1. An attachment for barrel-taps, comprising a ring-shaped collar, upright posts on said collar, a lower cam-ring provided with slotted segmental extensions guided on said posts and with an operating lever-handle, and an upper cam-ring guided vertically on said posts.

2. An attachment for barreltaps, comprising a ring-shaped collar, a lower camring guided on said collar and provided with segmental extensions having slots concentric 'with the tap, upright posts attached to said collar, an elastic packing ring below said collar, upright posts attached to said collar, a lower cam-ring provided with slotted segmental extensions guided on said posts, an upper cam-ring provided with ears connected with said posts, said cam-rings having adjacent cam-faces, and a lever-handle attached to the lower cam-ring.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
