BUNG.

SPECIFICATION forming part of Letters Patent No. 550,446, dated November 26, 1895.

Application filed April 9, 1895. Serial No. 545,053. (No model.)

T0 all whom, it may concern:

Be it known that we, EDWARD J. GLENNAN, of New York city, and MARTIN J. REILLY, of Brooklyn, New York, have invented an Improved Bung for Barrels, of which the following is a specication.

This invention relates to an improved bung for barrels of the kind in which the opening andclosing of the discharge-orifice are effected automatically by the introduction or removal of the faucet.

The invention more particularly consists in the construction of the parts for effecting the engagement of the faucet with the valveplug that controls the discharge-orifice.

In the accompanying drawings, Figure l is a longitudinal section of the bung, showing the valve closed. Fig. 2 is a rear view of the faucet; Fig. 3, a longitudinal section of the bung, showing the valve open; Fig. 4., a section on line 4 4., Fig. 3. Fig. 5 is a longitudinal section of the rear end of the faucet; Fig. 6, a side view of the valve-plug, and Fig. 7 an end view thereof.

The letter d represents the threaded sleeve of the bung adapted to fit into the tap-hole of the barrel-head A. The sleeve a is provided on its inner face with the forward righthand thread c and the rear left-hand thread d2, of which the thread a is adapted to be engaged by the faucet b and the thread a2 is adapted to be engaged by a solid valve-plug c. This valve-plug is more fully shown in Figs. 6 and 7, and consists of the threaded body, to the rear face of which a washer c is attached by means of 'a screw c2. At its front the valve-plug is provided with a central forwardly-projecting stem c3, carrying the laterally-extending feather c4. The bore of the sleeve a is reduced back of the thread a', and three (more or less) longitudinal ports a3 are formed in this thickened portion of the sleeve by mutilating or partially cutting away the thread c2.

When the valve-plug c is in its rearmost position, it closes the rear inlet-orifice a4 of the bung; but when the plug is drawn forward the liquid flows through said orifice and the ports d3 into the forward widened bore of the bung and thence into the faucet.

The faucet 5, adapted to operate the plug c, is constructed with a central bore b', adapted to embrace the valve-stem c3, and a communicating groove b2, adapted to embrace the feather c4. The rear face b3 of the faucet is made with a spiralpitch, at the deepest point of which the groove b2 opens, and thus the faucet may be made to engage and to be gradually screwed over the stem cs and feather c4.

To tap the barrel, the threaded shank b4 of the faucet is screwed into the threaded section a of the bung. As soon as the faucet engages the valve-stem and feather it will revolve the valve to draw it off its seat. Thus the liquid will iiow, as already described, out of the barrel and into the forward part of the bung, from whence it passes into three, more or less, longitudinal ducts b5 of the faucet. These ducts are bored around the central perforation b' and deliver the liquid into the forward part of the faucet, to be thence discharged bythe cock biin the ordinary manner.

A revolution of the faucet in the opposite direction will withdraw it from the bung and will at the same time screw the valve-plug home upon its seat to close the inlet-orifice a4. Thus it will be seen that the opening and closing of the valve are eected by the introduction and removal of the faucet in a simple manner, and that the operation of the parts is positive and very reliable.

What we claim is- The combination of a sleeve having an inner right and left hand screw thread, a rear orifice and rear ducts with a threaded valve plug having a forwardly extending stem and feather, and with a faucet having a central bore, a communicating groove, surrounding longitudinal ducts, and a rear beveled face, substantially as specified.
