To all whom it may concern:

Be it known that I, MICHAEL P. SCHMIDT, a citizen of the United States, and a resident of the city of Bellevue, in the county of Campbell and State of Kentucky, have in vented certain new and useful Improve ments in Bung-Extractors, of which the following is a specification.

The principal objects of my invention are to provide an instrument for extracting a bung from a barrel, which shall be very efficient in use, shall preserve the barrel for future use, shall provide means for making the initial hole wherein the screw of the extractor can be inserted and the screw thread of the said screw be the better enabled to make initial engagement with the wood of the bung, and finally be simple in construction and can be cheaply manufactured.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawing making a part of this specification, and in which similar characters of reference indicate corresponding parts,Figure 1 represents a side elevation of a bung extractor embodying my invention partly in section. In this view, the bung and the adjacent portions of the barrel are shown in vertical central section. Fig. 2 is a top view of the extractor, from which the handle is omitted.

I will now proceed to describe my invention in detail. There is present a frame A. This frame consists of a broad piece A provided at each end with a downwardly extending piece A These pieces A A respectively constitute the legs of this frame, and the whole constitutes a table or raised platform. This table A has a vertical central opening, and through this latter there extends the shaft B, provided at its lower end with the screw thread B This screw thread B has a gimlet point of the usual well known shape and construction. This shaft B is free to turn in the said central opening of this frame: table.

The preferred means for preventing the shaft B from sliding through the table A consists as follows: I provide a circular collar C and I locate this on the shaft B, and fix it to the said shaft by means of a bolt or rivet C Directly above this collar C, I locate a broad stop piece D. For convenience in construction, this stop piece D has at each side a vertical leg D and this leg is at bottom connected to a flange or foot D which latter rests on the table A and extends outwardly from the shaft B. Each flange is connected to the table A by a suitable screw or bolt D Thus this stop piece D is held firmly in position by these bolts D It is to be understood that the shaft B is free to turn in this stop piece D. By the foregoing construction, the shaft B is free to rotate in either direction, but cannot move vertically up or down, independently of the table A The shaft B is rotatable by a handle, and the preferred construction of this handle is one of my invention. The upper end of the shaft B is squared or faced, and tapered.

Thus B B, B B, respectively indicate the tapered faces of the shaft B, when the latter has four faces. A. handle E has an angulated central tapered opening E adapted to fit upon the said tapered faced portion of the shaft B, and the respective faces of this opening in the handle are adapted to respectively engage the respective adjacent faces of the shaft B. Of course, the faces B might not be tapered, in which event the faces of the shaft B would not be tapered. But this aforesaid tapered construction is preferred. One end of the handle E is provided with a point at E with which a preliminary depression can be made in the bung, so that the gimlet point B of the screw may readily and effectively engage the wood of the bung and carry the screw B forward as it is rotated, so as to screw into the bung. The screw portion B B extends below the plane of the bottom of the legs A A of the table frame A, A sub stantially to the extent shown.

The mode in which my invention is employed is as follows: E is a bung which has been forced into the bung hole H of barrel K. The handle E is removed from the shaft B. The point E of the handle E is placed against the center of the top of this bung H, the handle being held vertical. The end E of the handle is then struck by a mallet or hammer, and a central depression is made in the bung. The handle E is now replaced on the shaft B. The frame table A is now located over the bung. The point B of the screw is inserted in the depression made in the bung H by the point E of the handle E. The handle E is now rotated, and the screw B advances into the bung H until the legs A A of the frame table A rests upon the barrel K. At this time the portions B 13 of the screw will have entered the bung H and have engaged it as shown in Fig. 1. The handle E is now continued to be rotated forward. This rotation will continue to cause the screw B to screw into the bung H, but as the table A of the table frame A cannot come nearer to the bung H, the latter is raised by the rotating screw B up toward the table A The rotation of this screw B is continued until the bung H is lifted far enough up and out of the hole H as to loosen the bung H in the said bung hole H The bung H can then be lifted out of the hole H The most convenient mode of doing this is by lifting the instrument already described as a whole directly from the barrel. The instrument carries with it the bung H. The bung H is now unscrewed from the bung, either by rotating the shaft B while the bung H is held stationary, or by rotating the bung H while the shaft B is held stationary. It is therefore evident that the objects of my invention are fully obtained.

What I claim as new, and of my invention and desire to secure by Letters Patent, 1s

1. In a bung extractor, the combination of the table, with legs forming a solid straddle frame, and the rotatable shaft provided with a gimlet pointed screw, and a collar fixed to the said shaft and located above the table, and the stop piece located above the collar and having end flanges whose terminals rest on the said table and are secured thereto, the shaft extending through the stop piece and turning loosely in the said stop piece and in the table, and means for rotating the said shaft, the point and the lower portion of the screw extending permanently below the plane of the bottom ends of the legs of the table.

2. In a bung extractor, the combination of the table, with legs forming a solid straddle frame, and the rotatable shaft provided with a gimlet pointed screw, and a collar fixed to the said shaft and located above the table, and the stop piece located above the collar and having end flanges whose terminals rest on the said table and are secured thereto, the shaft extending up through the stop piece and turning loosely in the said stop piece, the point and the lower portion of the screw extending permanently below the.

plane of the bottom ends of the legs of the 3 table, the screw-shaft having an angulated tapered upper end, and a removable handle having an angulated opening adapted to re;- ceive the angulated tapered end of the said shaft, and provided with a pointed end.
