TAPPING DEVICE.

SPECIFICATION forming part of Letters Patent N 713,1 13, dated November 11, 1902.

Application filed July 25,1901'. Serial Nd. 69,629. (No model.)

enable those skilled in the art to which it appertains to make and use the same.

This invention relates to that class of devices which are forced into the bung-hole of a barrel, keg, or other vessel to drive the bung into the vessel and tap the contentsthereof;

and the object of our invention is to provide a device of this class which is simple inconstruction and operation and by means of which the tapping of the vessel may be quickly and easily accomplished without use of va hammer or similar device; and with this and other objects in View the inventionconsists of a device of the class specified constructed as hereinafter described.

This invention is fully disclosed in the fol-` lowing specification, of which the accompanying drawing forms a part,in which the separate parts of our improvement are designated.

by suitable reference characters, said drawing being a central vertical section of our improved tapping device and showing'the same connected with a barrel or other vessel.

In the use of a device embodying our invention it is customary for the barrel or other Vessel A to be provided with a bung-bushing B, screwed or otherwise secured therein and provided with an upwardly-directed flange or rim B', preferably of greater diameter thanv the body portion ofthe bushing and screwthreaded interiorly, and in the bushing 'B is inserted the bung C, which may be of the type shown in the drawing or of any other preferred iorm.

Our improved beer-tapping device embodies a tubular casing D,screW-threaded at its lower end, as shown at D, so as to be screwed into the liange Bof'the bung-bushing, and above the screw-threaded portion D is a flange D2, beneath which is arranged a packing-ring D3.

At one side of the casing D is a laterallyarranged pipe E, in which is secured an airinlet tube F, adapted exteriorly to receive a rubber tube in the usual manner and open the inner end of the tube F.' Within the pipe E is secured a rubber valve F2, the lips F3 of which are normally contracted, but will open under pressure of air, and our improvement is adapted more particularly for tapping barreis, kegs, or other vessels containing beer or similar liquor or liquids containing gas or liquids under pressure,and the barrel or other vessel A is supported with its bung-hole up, as shown in the drawing.

The top portion of the casing D is enlarged at the upper end thereof, as shown at G, and said enlarged portion is screw-threaded interiorly, 'and at the bottom thereof is an annu- .lar shoulder D4, upon which is mounted a packing-ring II.

lVithin the screw-threaded extension orenlargement G is Vplaced a screw-threaded plug or head I, provided with projecting lugs or handles I upon either side thereof and provided at lits lower end with an integral downwardly-directed cylindrical or tubular extension or tube J, which lits Within the casing D, but is of such diameter as to form an ann ularair-space D5 between the same and said casing, andsaid tube is of such length as to project appreciably below the casing in the normal position of the plug I, and said plug is exteriorly threaded, so that the rotation thereof causes it to descend into the extension G of the casing D and force the tube J downwardly.

The tapping-tube K may be of any desired length and constitutes the draw-0E tube and isprovided with a conical or pointed lower end K', in which are 'formed a plurality of apertures K2, through which the liquid or liquor is passed into and out through said tube. The tube K is inserted through the head or plug I, and while fitting tightly therein is adapted to slide freely therein and in the tube J, and the upper end of the tube K is in practice provided with a spigot or other suitable valve or draw-oft' device in the usual manner, said valve or draw-off device being not shown. The upper end of the plug or head I is centrally recessed, and placed therein is a packing-riugH, above which is placed a nut L, which may be screwed down into said packing-ring in the usual manner, and the said n ut L and plug lare correspondingly threaded.

The operation of this device will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the following statement.

The appliance having been inserted iu the bung-hole ofthe barrel by screwing the same into the flange B, the plug or head I is turned to bring the lower edge of its extension-tube J slightly in contact with the bung. The tapping-tube K is then drawn down so as to similarly rest upon the bung, and the nut L is tightened to the greatest possible extent against the packing H'. lt will be manifest that within the scope of our invention other means may be employed for securing the tapping-tube adjustable to the head or plug I. The tubes J and K being thus in mutuallyadjusted position, the head or plug is rotated by means of its lug or handle I or through the medium of any suitable instrument applied to it, so that the lower edge of the extension-tube J bears down upon the bung and either drives it into the barrel or breaks through it and forces the lower portion th ereof into the barrel, this being dependent upon the style of bung which has been employed to seal the package. As the tapping-tube K is secured in its adjusted position by means of the nut L, it will be carried downwardly with the tube J, and will therefore be properlyand effectivelyin position to receive the fluid therethrough the moment it is able to leave the barrel. lt is not essential that the lower end of the tapping-tube K should be actually in contact with the bung, nor is it essential that the tapping-tube K should be actually in contact with the bung, nor is it essential that the tapping-tube peform any of the work of pushing in the bung. The tapping-tube may immediately or at any time during the constant or intermittent withdrawal of the contents ot' the barrel be vertically adjusted relatively tothe plug or head I and to the liquor in the barrel by loosening the nut L, sliding the tube K downwardly, and then again tightening the nut L. As the contents of the barrel are withdrawn and the pressure in the cask becomes less the escaping air-pressure from the outside of the tube F will open the lips F3 of the valve F2 and permit sulficient air to enter to maintain the proper pressure in the barrel; but however great the inside pressure of the gas of the beer the liquid itself cannot escape through the valve F2, as its lips F3 will be but more tightly contracted. The especial forni of valve is not new, and this portion of the device forms no essential part of the invention, except broadly as an element contributing to the effect-ive operation of the device. The liquor flows through the opening K2 into the pipe K and out through the spigot K3 thereof. The packin gs H and H make the casing D and the tube J tight against liquid air or gas. The packing AH is tightened by the nut L after the tube K is once adjusted, and the packing Il may be tightened byscrewing down the plug I.

Having fully described our invention, what we claim as new, and desire to secure by Letters Pat-ent, is-
