`-To all whom t may concern: f'

ll, ALBERT Ml Munzin- GER, residing at Williamsport, in the county of Lycoming and State of Pennsylvania,

Be it known that.

vhave invented certain new and useful .lfm-

provements in Bung-Withdrawing Maf chines, of which the following is a specifica-l tion.

ll/lty invention relates to a bung withdrawing machine, vision of a compact and eH'ect-ive machine for the purpose stated, which cuts through the bung progressively and removes it ina single operation. Bungs are ordinarily made of soft -poplar wood highly compressed so that they expand after have been tightly driven into the bung""hole. rll`heir removal is therefore 'diiiicult Usually they are chipped out bit by bit, a tedious operation which also has the disadvantage that pieces of t-he bung may fall through the bung hole. v

My machine has aslicing action and makes a helical cut through the bung while it is still in place, and then in the same' operation by further rotation. removes it, the bung, as it is raised out of the hole, ordinarily breaking and falling from the tool, dislodged from the tool by the next bung removed. This dis integration is the result of the cutting into the bung and of the displacement of the material of the bung and its consequent weakening and further compression while it is still in position by the tool which is relatively large with reference to the bung. the removal of the bung is the action obviously to be expected when the bung is no longer held together by the portion of the barrel surrounding it.

My invention consists in a bung extractor of the general nature illustrated in the drawings described in the specification, and more particularly pointed out in t-he appended claims.

Referring to the drawings: Figure 1. is an elevation of my machine parts being shown in section. Fig. 2. is a side elevation, the tool being shown in a position slightly different from that illustrated in Fig. 1. Fig.

Application filed December 22, 1908. Serial to. 68,801.

This .shaft is provided with a metal casing 2 on the end of which is screw threaded a supv port having legs 3, preferably three in number, which during the operation of the machine are designed to be drawn down upon the port-ion of the barrel adjacent the bung hole and for that purpose have beveled or 'llhe legs 3- are located symthe axis of the support metrically about tool about to be which is also the axis of the described.

The shaft l is provided with a rotatable spindle l having a screw-threaded end onto which is adapted to be screwed tool 7. rll`his tool may of course be secured in any other suitable manner. lits upper end is close up against the metal casing 2 preventing upwardmotion of the tool with respect to the support. Downward motion is prevented bythe nut or collar 8 screwed onto the met-al casing '2 above the over the same.

rlhe tool 7 is in the nature of an auger land is provided, with a starting screw 9 or other centering means atl itslower end and with a' cutting up and removing helix 10 immediately above the starting screw. It does not, however,v merely bore a hole through the bung but, as stated, slices through it, the blade at the lower end of the helix lying in a plane intersecting at a sharp angle a plane at right angles to the axis of the helix adjacent said cutting blade. rll`he parts sliced through are not in that operation removed but the entire bung disintegrates when it has been removed from the bung hole. rllhe exterior of the helix, as shown, is non-cutting. rlhis helix forease of operation, is' preferably of uniform internal and external diameter, that is, the auger, if solid would form a cylinder and, if the thread of the auger were removed, would likewisev form while this is the preferred construction, it is not to be inferred that no other arrangement would be operative. Irlhe helix 10, as will shortly appear hereinafter, is in the nature of a slicer by reason of the construction of its lower end. lt is of low pitch and of considerable di# ameter extending well out toward the edge of the bung. rll-he blade at the lower end of thehelix extends well out from the axis of the helix toward the edge of the bung and is so located as to intersect at a shar angle a plane at right angles tothe axis support and projecting of the helix' adjacent said cutting blade. The cutting blade thus enters the bung at a sharp angle to its surface and with a slicing action.

The legs 3 are of such length that the starting i screw and auger have passed through the bung just before the ends ofthe legs rest upon the surface of the barrel. Once this relative position is reached further rotation of the tool raises the bung out of the hole and, as above stated, the bung will ordinarily ex and and break up so that it will fall in pieces from the tool automatically. However, should this action fail to occur, the bung will be forced off when the next bung is removed.

Many bungs are made with the grain of the wood running substantially horizontal, and to such bungs my machine is peculiarly applicable, since it acts substantially with the grain. After the starting screw has entered the bung, the sharp cutting edge at the lower end of the auger is forced into the top of the bung and the rotation of the tool feeds it through the bung, cutting a helical path so that the machine progressively cuts through the bung while still in place and then removes it in a single operation. The machine may obviously be driven by hand or by power. In Fig. 4 I have shown a compact form' of the device in which a motor 12 is mounted co-axially with the tool and above it being supported by the legs 3. This motor may be of any desired nature electrical or otherwise. Between the mot-or and the tool is a casing 13, containing reducing gearing 14 operatively connecting the motor with the tool.

It will beA apparent that by this device bungs may be removed .completely and eX- peditiously, and by a single operation.

What I claim as my invention is- 1. A bung withdrawing machine comprisi ing a support, and slicing means rotatably mounted in said' support and provided with a helix having a non-cutting exterior and a slicing blade lying in .a plane intersecting at a sharp `angle a plane at right angles to the axis of thehelix adjacent said' cutting blade.

' 2. A bung withdrawing machine comprising a shaft, a support carried by said shaft y adjacent its end, and adapted to be drawn down upon the barrel in the' operation of the machine, and a slicing tool on the end of said shaft provided with centering means and with a helix of low pitch and of much j greater diameter than said centering means and having a transverse slicing edge extending well out from the axis of said helix and located 1n a plane intersecting at a sharp angle a plane at right angles to the axis of a slicing device above the same having at4 its lower end a slicing blade extending well out from the axis of the helix and lying in a plane intersecting at a sharp angle a plane at right angles to the axis of the helix adjacent said cutting blade.
