TAP Foa BEER, sac.

SPECIFICATION forming part of Letters'Patent No. 248,262, datedOctoloer 11, 1881` To all lwhom it may concern Be it known that I, JOHN F. PAULFRANZ,

a subject of Bavaria, Germany, residing in the whichof the plug.

Figure 1 is a side elevation of the cap of the tap embodying my invention. Figs. 2 and G are end views thereof. Fig-3 is a side view Fig. 4 is an end view thereof'.

Fig. 5 is a longitudinal section of the complete device.

Similar letters ot' reference indicate corresponding parts in the several figures.

My invention consists of a plug to be attached to the barrel, keg,'&c., and containing a valve, a cap to be secured to the plug provided with means for causing the proper register of the parts and expansion of packing, and a cock adapted to open the valve of the plug provided with means for attachment to the cap.

Referring to the drawings, A represents a tubular plug, which is eXteriorly of cylindrical, conical, or other suitable form, and adapted to be inserted in the tap-hole of a barrel, keg, Sto., containing beer or other liquid, said plug having an opening, a, for the passage of the liquid from the keg. Within the plug is fitted a sliding valve, B, which is held closed, covering the opening a by means of a spring, C, which bears against the plug and valve, as shown in Fig. 5'. The head b of the plug has formed on its circumference spiral grooves D, and in its front end one or more openings, c, and the surface of the plug adjacent to the head may be threaded for screwing the plug to the keg in the tap-hole, as above referred to.

E represents a cap consisting of a shell, d, which is adaptedto encircle the head b of the plug, and containing a tubular block, F, from whose inner face project studs or pins e, which are adapted to enter the openings c ot' the head of the plug A. The outer or forward face of l the block F has a tubular extension, Ef, which Application tiled July 13, 1881. (Model.)

H represents handles, which are secured to the cap E for the purpose ofrotating the same; and J represents studs or pins projecting inwardly from the shell of the cap, adapted to enter the spiral grooves D of the plug A, each stud and. handle in the present casel being formed of' one piece ot" metal.

K represents` packing of suitable material, placed against thc block F on the side opposite to the extension E', the pins e passing through the packing,land the center of the latter being perforated for the passage ofthe shank or inlet-branch ot' the cock G, the packing, when the parts are in position, abutting against. the front end ot' the head ot' the plug A. The cock G is ot ordinary construction excepting the attachment of thespring catches or fastenings F', and has at its inlet end an opening, a', which is adapted to register with the opening a ot' the plug A.

L represents a washer, which is titted on and secured to the extension E of the block F,and

-abuts against the front walLf, of the cap E,

the latter thus being held in position by the washer L and block F on opposite sides ofthe front walhf, of said cap.

M represents a pin, which is secured to the rotary cap E,'and projects horizontally forward from the front wa-lLf, thereof. A portion of the circumference of the washer L is cut away, as at 7L,the ends ofthe portion forming shoulders k, which limit the motion of the pin M, the location and play of the latter being in said cut-away portion It.

The operation is as follows: When the plug A is in position,the valve B, pressed outwardly by the spring C, closes the opening a and prevents escape of the liquid from the keg. When the keg is to be tapped the cap E is fitted to the head b of the plugA. For this purpose said cap is rotated either by the handles H or the pin M until the pin strikes either of the shoulders h of the washer L. This places the studs J and pins e in such positions that they register, respectivel y,with the spiral grooves D and the openingcof the head of the plug. Then press the cap to full extent over the head of the plug and rotate it, wherebyit is screwed to and wedged tightly on the head of the plug. As the packing K is pierced by the pins e it is prevented frorn being turned and thereby injured,


but being pressed by the block F against the head ofthe plug,itis compressed and expanded, thusformingatightjointbetween thecap, plug, and block, and also bears tightly around the inlet branch ofthe cock when the latter is applied,thus preventingleakagebetween'the plug and cock. The cock is now forced through the bore ofthe extension E', block E, and plug A, thus pressing back the valve B and uncovering the opening a ofthe plug, and causing said opening to register with the opening tt' of the inlet branch of the cock. When the catches F of the cock reach the notches or shoulders g of the extension E they engage with them, so that the cock is irinly connected to the cap, and all the parts are held in operative position. It is now evident that the beer, &c., may be drawn silnplyby properly turning the plug ofthe cock. By operating vthe fastenings F so that they leave the notches or shoulders g, the cock, under action ofthe spring-pressed valve B, leaves the cap and plug, or may be withdrawn there Jfrom,the valve B immediately closing and covering the opening a. The cap is then rotated so that the studs J are released from the spiral grooves D of the plug, and thus the cap and plug are separated. The plug may be removed or remain a fixture ofthe keg, Src.

The valve B is of the forno of a -hollow cylinder, so as to receive the spring C, by which construction I ain enabled to use a shoot-valve and spring, and inclose the latter.r Access is had to the valve and spring by means of the screw-cap A', which forms the end ofthe plug opposite to the head b thereof, one end ofthe spring abutting against said cap.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. The plug A, having an opening, a', and 4o a head,b, with spiral grooves D, and the rotary cap E, with studs J, combined and operating substantially as and for the purpose set forth.

2. The rotary cap, E, the tubular block F, with extension i', and the plug A, combined and operating substantially as and for the purpose set forth.

3. The rotary cap E,with studs J, tubular block F, with pins c, the plug A, with spiral grooves D and openings c, and the washer K., combined and operating substantially as and for the purpose set forth.

4. The rotary cap E and plug A,in combination with the pin M and the shouldered'washer L, substantially as an d for the purpose set forth.

5. The plug A and rotary cap E, in combination with the block F, formed with a tubular extension, E', and the washer L, said cap encircling the bloclqand the washer being tixed to the extension, the washer and block being on opposite sides of the front wall ofthe cap, substantially as and for the purpose set forth.

6. The plug A and cock G, in combination with the valve B and spring C, said valve being of hollow cylindrical form, inclosing the spring, substantially as and for the purpose set forth.

7. The plug A, the block F, the tubular extension E', having shoulders g, andthe cock G, havingcatchesF,combinedandoperatingsub- 70 stantially as and for the purpose set forth.
