SPECIFICATION arming' part of Letters Patent No. 589,237, dated August 31,1897.

Application sied May 25, 1897.

Be it known that I, WlLLIAM B. BAKER, a citizen of the United States, residing at Newport News, in the county ofrWarwick and State of Virginia, have invented new and useful Improvements in a Combined Beer Tap, Cooler, and Pump, of which the following is a specification.

This invention relatesto a combined beer tap, cooler, and pump; and it consists in the novel features of construction and combinations of parts in such an apparatus, as hereinafter described and claimed; In the annexed drawings, Figure 1 is a perspective view showing the arrangement of parts in a beer tap, cooler, and pump constructed according to my invention. Fig. 2

is an enlarged' sectional view of the pumpwith bar-faucet in side elevation. Fig. 3 is atop view of the pump and bar-faucet. Fig. 4 is a plan of the cooler with cover removed. Fig. 5 is a cross-sectional elevation of the cooler. Fig. 6 is an enlarged sectional elevation of the drawing-olf pipe, bung-plug pro? vided with stuffing-box, and a recessed bungdriver surrounding the drawing-off pipe and normally resting on the bung-plug. Fig. 7 is a plan or top view of the bung-plug with drawing-off pipe in cross-section.

Referring to the drawings, the numeral 1 designates a barrel or keg from which beer is to be forced into and through a cooling-coil or tortuous passage 2, Figs. 4 and 5, located in the lower part of a refrigerating-tank or ice-chest 3, Fig. 1, supported at a convenient elevation for drawing off the beverage as required.

There is inserted into the bun g-hole or suitable aperture of the keg a conical metal plug 4, Figs. 1 and 6, having a somewhat enlarged cylindrical head 5, as shown. This bungplug4 and head 5 are centrally bored for passage of a drawing-off pipe G, having in its lower end a series of inlet-openings 7, through which the liquid contained in the keg will enter the said pipe under the pressure of the gas in the keg or by an air-pressure forced onto the surface of the liquid, as presently explained.y

Between the pipe 6 and the bore of the plug 4 there is a sufficient annular passage saai no. 638,109. (No modem 4t, Fig. G, to permit the introduction of air into the keg through an vairinlet nozzle S, tapped into the head 5 of said plug. On the outer side of the head 5 there is an externally-threaded boss 9 for engagement of a hand-nut or screw-cap l0, which is suitably recessed to inclose a washer or packing 11 for making a stuffing-box or close joint around the vpipe 6 outside ofthe plug` 4 to prevent the escape of gas or air from the keg.

Surrounding the pipe (i and normally resting on the plug-head 5 there is a cylindrical plug-driver 12, Figs. 1 and 6, which is suitably recessed or cored to inclose or surround the nut or boxing 10, so as to prevent janr ming or other injury thereto in driving the plug. The plug-driver 12 is provided with a handle 13, also surrounding the pipe 6, and which can be convenientlygrasped for actuatin g the driver to force the plug into place.

It Will be observed that the plug-driver completely surrounds the drawing-off pipe G and rests normally on the head 5 of the bungplug 4, so that it is always ready for instant use. By providing this driver there will be no need for employing an ordinary hammer or mallet to drive the plug, and which would be liable to deliver its blows unequally and jam or mash the plug-head and nut. The plug-driver 12, being operated on the pipe G as a guide and never in contact with the nut 10, cannot possibly injure the said nut or stuffing-box and will always drive the plug true and without battering or mashing.

At a convenient point on the pipe 6 there is preferably provided a cock 14, that may be closed whenit is desired to disconnect the drawing-off pipe from the keg. By means of a screw-coupling 15 there maybe attached to the pipe 6 or cock 14, as shown, an elbow 16, from which is extended a suitable length of flexible tubing 17 to connect with a short piece of pipe or pipe-coupling 18, which in turn connects with the inlet-nozzle 19 to the cooling-coil or lengthencd tortuous passage 2 in the ice-chest or refrigerating-tank.

The coil or tortuous passage 2 is inclosed in a casing 20, removably located in the lower part of an ice chest or chamber 3 of any suitable construction. This tortuous passage 2 may be formed in any convenient manner in IOO the bottom part of the casing 20, and the said casing is covered by a lid or plate 2l, fastened to the casing in such manner as to be removable. Ice is to be placed upon this plate or casiugcover 2l and around the casing 20, so that the beer, in passing through the lengthened passage or coil 2, will be thoroughly cooled. At the termination of the coiled or tortuous passage 2 there 'is an exit-nozzle 22 for connection with a bar-faucet 23, through which the cooled beer is to be drawn.

The faucet 23 may be provided with a lug 24, to the sides of which are pivotally attached two links 25, that pivotally connect with the bifurcated end of a hand-lever 2G, having an arm 27, that is jointed to or pivotally connected with the piston-rod 2S of an air-pump that is located in the upper part of the ice chamber or chest. It will be observed that the linked connection of the hand-lever 26 with its support alfords a movable fulerum for said hand-lever, which with the jointed connection of the lever-arm 27 and piston-rod 28 will cause the pump-piston to move always in a straight line.

The air-pu1np cylinder 29 is connected to a plate 30 to be secured on the outside of the refrigeratin g chamber, tank, or chest. A depending` extension 3l of this plate 30 will afford support for the faucet 23, through which the beeror otherliquid is drawn. 0n the air-pump cylinder 29 there is an annular flange 32 at a distance from the plate 30 about equal to the thickness of the ice-chest wall. The plate 30 is on the outer side of this wall and the flange 32 is on the inner side. Bolts 33, extended through the plate 30, ice-chest wall, and flange 32, will serve to rigidly secure the air-pump in position.

The piston-head of the air-pu 1n p consists of two plates 34 and 35, between which an expansible packing 3G is secured. One of the plates, as 34, may be rigid on the piston-rod 28 or held against a shoulder thereon. The other head 35 'is slipped onto the piston-rod after the packing 3G has been put in place. This head or plate 35 is cupped, as shown, or peripherally flanged to afford support for the extended rim of the packing 36, vwhich is bet-ween the bore of the cylinder 29 and the flanged rim of said plate 35, and in order to subject the packing to compression and force it firmly and expansively against the cylinder-bore there is provided a spring 37, held by a cap 38 and nut 3S) on the end of the piston-rod. Obviously the nut 39 can be tightened so as to cause the spring 37 and plate 35 to exert any required compression and peripheral expansion of the packing.

The inner end of the air-pump cylinder is screw-threaded forconnection of a removable head 40 with a packing-ring 4l interposed. This cylinder-head 40 is perforated for attachment of a pipe 42,which connects,through a T-coupling 43, with branch pipes 44 an d 45, one for inlet of air to the pump-cylinder and the other for exit of air under compression to be forced into the beer keg or barrel l when necessary. lu each of the branch pipes 44 and 45 there is located a cheek-valve 46 of suitable construction. The air-exit pipe, as 45, will be extended ou tside the ice-chest or refrigerating-chamber through one wall thereof, and to this pipe is attached a suitable length of flexible tubing 47 to connect with the air-inlet nozzle 8 on the bung-plug 4 at the beer-keg. Thus whenever the pressure oi' gas in the keg or liquid-receptacle is insufiicient to force the beer orother liquid through the pipe (3, tubing 17, and cooling coil or passage 2 the air pump can be operated by means of the handflever 26 to force-the beer to the coil or passage 2, whence it may be drawn by the bar-faucet.

As the air-pump is located within the icechcst and takes its supply of air therefrom the liquid in the keg, barrel, or other receptacle will be subjected to direct action of this cold air when the pump is operated. On reaching the lengthened passage or coil in the icechest the liquid will be still further cooled therein before it is finally drawn off for use.

What l claim as my invention is- 1. The combination of a pipe for drawing oif liquid, such as beer, from a keg, or barrel, or other receptacle, a bung-plug-through which the said pipe is passed with an annular passage between the pipe and plug, an air-inlet nozzle communicating with the side of said annular passage, a stufling-box at the outer end of said passage, a bung-driver permanently surrounding the drawing-off pipe, an ice chest or chamber having therein a cooling coil or passage connected at one end with the said drawing-oft pipe and provided at the other end with a faucet, and an air-pump located in the ice-chest and having a pipe connected with the air-inlet nozzle of the bungplug, substantially as described.
