DEVECZE. FOR TAPPING BEER.

EPECIPICAI'ION forming part of Letters Patent No. 296,311, dated April 8, 188%.

(No model To LLZZ whom it may concern:

Be it known that I, Jnnnran H. BRENNAN, a citizen of the United States, residing at Boston, int-he county of Sufiolk and State of Massachusetts, have invented certain Improve ments in Devices for Tapping Beer and other Barrels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation of a beer-faucet and bushing constructed in accordance with .IDY invention. Fi 2 is a longitudinal vertical section through the center of the same ap plied to the head of a barrel. Fig. 3 is aview of the removable screw-plug which contains the valve-seat. Fig. 4 is a view of the inner end of the stem or neck of the beerfaucet.

My invention relates to certain improvements in devices for tapping beer and other barrels, and has for its object to enable the valve and other parts contained within the bushing to be easily removed without taking the bushing out of the barrel-head, thus greatly facilitating the operations of cleansing and repairing the parts, and also avoiding the undue enlargement of the tap-hole, and consequent spoiling of the head of the barrel, which re sults from frequently removing and replacing the bushing; and'my invention consists in certain details of construction-and combinations of parts, whereby the desired results are attained in a simple and eifcctualmanner.

in the said drawings, A represents the head of abeer-barrel, within the tap-hole of which is screwed the tapering bushing B,pr0vided with an external screw-thread,tl1is bushing being intended to remain permanently within the head A. The rear portion, a, of the bushing, which projects beyond the inner surface of the head, is turned down smooth on the outside, and is provided with a series of perforations, Zr, forming a strainer through which the beer passes to the chamber 0.

D is a removable cylindrical plug, which is provided with an external thread, 6!, which engages with a thread, 6, on the inside of the portion f of the bushing, the plug D having square notches or recesses g in its front end for the reception of the end of a suitable implement, by means of which the plug can be turned in or out of the bushing, the latter being provided with a shoulder, 10, against which the plug is seated, as seen in Fig. 2. On the inner end of the plug D is formed an annular scat, h, for the valve i, the stem of which projects through a central aperture, Z, in the plug D into a recess, m, in the. front thereof, the inner portion of the stem 7; being of increased diameter, to afford a larger bearing-surfacc and reduce the wear on the parts.

Within the chamber 0 is placed a strong spiral spring, G, which is guided and maintained in its proper central position with respect to the valve by means of a guide stud or pin, a, projecting from the rear of the valve, and asiniilarguidc'stud, p, arranged opposite thereto and projecting from the rear end of the chamber ctoward the valve. central portion, 12, of the plug Dis provided with a series of small apertures, q, arranged in a circle around the aperture Z, these perforations q forming a second strainer, through which the beer flows when the valve i is forced back from its seat 71 against the resistance of the spring G by a protuberance, r, at the center of the inner end of the stem sot the faucet H as the latter is screwed into the bushing. The stem sis provided at its rear end, 13, with an external thread, it, which engages with the internal thread, 0, of the bushing, and at the opposite end of the stem 8, close to the shoulder n, is another externally-threaded portion, a, of slightly larger diameter than the portion 13, which engages with a correspondingthread, b, on the inside of the mouth of the bushing B, at the outer edge of which is an annular groove, 15, for the reception of the shoulder a of the faucet, by which construction a tight joint is insured and the front end of the stem of the faucet is firmly supported at both ends, as requircchwhile by providing the stem 5 with a short thread, I, at its rear end and another short thread, a, of slightly larger diameter at its opposite end with a smooth non-threaded portion between thcn1,tl1e necessity of cutting a thread along its entire length is avoided and the time required to screw it into the bushing greatly reduced.

The inner end of the faucet H is closed and is provided with a series of small perforations, 0, arranged in a circle around the protuber- The web or ance r, a third strainerbeing thus provided in the faucet itself, in addition to the two strainers of the bushing, which insures the liquid being freed from all particles of foreign matter.

It will be apparent that whenever it is required to cleanse the interior of the bushing and parts contained therein, or gain access to the same for repairs, it issimply necessary to turn the plug D with a suitable wrench or other implement until it is clear of the thread 6 of the bushing, when it can be readily taken out, together with the valve viand spring G, no removal of the bushing B from the barrelhcad being required, and the wearing out of the tap-hole,and the consequent spoiling of the head of the barrel, heretofore caused by the frequent removal and replacing the bushing as heretofore,being thus entirely avoided, and a saving in time and labor also effected. As the faucet is unscrewed from the bushing, the spring G will tightly close the valve 6, thus preventing any escape of the beer or gas, in case it should be desired to remove the faucet before the barrel is empty, and also keeping the barrel air-tight.

I am aware that a bushing has been provided with a valve adapted to be opened against the resistance of a spiral spring by a faucet, as the latter is screwed into the bushing; hence I make no broad claim to such construction, confining myself to the details of construction and combination and arrangement of parts herein specified.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a barrel-tapping device, the externallythreaded bushing B, having at its inner end the perforated chamber 0, and provided with an internal thread, 6, and shoulder 10, in combination with the removable screw-plug D, adapted to be inserted into and taken out from the front end of the bushing, and having the valve-seat h and a web, 12, provided with a series of perforations, q, arranged around the central aperture, Z, in front of the valve-seat, the valve d, with its stud n, the spiral spring G, and the stud p, projecting inward from the rearend of the chamber 0, and the faucet H, adapted to brought into contact with and press back the stem of the valve 2' as it is screwed into the bushing, the whole constructed and arranged to co-operate substantially in the manner and for the purpose set forth.

2. In a barrel-tapping device, the combination, with the bushing 13, removable screwplug D, having a recess, an, in its'front side, and a series of perforations, q, the valve i,with its stem k, projecting into said recess m, and the spring G, of the faucet H, provided with an external thread, 15, and having its inner end closed and provided with a protuberance, r, surrounded by a strainer formed of a series of perforations, c, all constructed and arranged to operate substantially in the manner and for the purpose described. H

3. In a barrel-tapping device, the combination, with the bushing B, provided with an internal thread,e, and asecond internal thread, b,at its mouth, of larger diameter, the removable screw-plug D, valve 2', and spring G, of the faucet H, having its stem 8 provided at its rear end with a thread, it, and at the opposite end with a shoulder, a, and a second thread, a, of larger diameter, with a smooth or nonthreaded portion between them, all constructed and arranged to operate substantially in the manner and for the purpose set forth.

\Vitness my hand this 30th day of October, A. D. 1883.

JERMIAH H. BRENNAN.
