Patented Feb. 10. 1874.
UNITED STATES PATENT OEEI E.
cEoEeE CORNELL, or CHICAGO, ILLINOIS.
IMPROVEMENT lN WRENCHES FOR INSERTING BUNG-BUSHES.
Specification forming part of Letters Patent No. 14?,24 1, dated February 10, 1874; application filed December 23, 1873.
To an whom it may concern:
Be it known that I, GEORGE B. CORNELL, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Wrenches for Inserting Bung- Bushes; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which myinvention appertains to make anduse the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a side elevation of the wrench detached from the bushing. Fig. 2 is a vertical central section of the same with bushing attached, cutting the same through the center ;v and Fig. 3 is a cross-section or plan taken on the line a: a, drawn across Fig. 2, showing the position of the parts which act to secure the bushing to the wrench.
Similarletters of reference indicate like parts in the several figures of the drawing.
My invention relates to that class of wrenches employed in securing metallic bushes within the bung-opening of casks, barrels, 850.; and the improvement consists in providing the shank of the wrench with an automatic adjustingeo're, consisting of a series of sections so arranged as to be automatically adjusted outward from the center uniformly, and against all parts of the inner surface of the bush, in such a manner as to cause the bush to retain its original annular circumference against the resistance of the wood while being turned into place by the frictional contact of the separate sections of the core, adapted to engage the inner surface of the bush in such a manner as to cause the same to revolve jointly with the core, whereby the bushing may be turned into place without assuming an oblique position within the bung-opening, all of which will be more fully understood by the following dcscription.
In the drawing, A represents the shank of the wrench, which consists of a plain metal bar of the requisite length. B is the core proper, which is substantially made of metal. This core is provided, near its upper end, with an aperture, through which the shank loosely passes; or the shank may be permanently attached to the core, if desired. The lower portion or base 0 of the core is made less in di= ameter than the upper or body portion, and is tapered, approximating the taper of the inner surface of the bush. The lower extremity of the body, at its junction with the base, is so formed as to' provide an inverted annular groove or channel, a, as shown in Fig. 2. The plan of this base is that of a pentagon, and its sides are slightly convexed, the curve terminating in the are of a circle at the corners of the sides, as shown in Fig. 3. D is a metal disk, which is attached to the lower extremity of the base. This disk is secured in place by means of a nut, d, and is so arranged as to admit of being removed, when desired. The upper surface of this disk is provided with an upward-projecting rim, e, forming an annular groove or channel, f, between its inner surface and the sides of the base. E is a metal facing, which is made round on its outer surface and tapered, approximating the taper of the inner circumference of the bush. This facing is adapted to closely fill the inner circumference of the bush, and is made in sections, corresponding in number with the number of sides on the base of the core. The upper and lower end of each section is so shaped as to loosely fit into the grooves af, as shown in. Fig. 2, and are so arranged as to admit of a free-andeasy movement toward or from the center. The inner surface of each section is made flat and adapted to bear against the adjacent side of the base, by which means the same are moved outward uniformly by an independent rocking movement of the core. G represents the bushing; but, as the same constitutes no part of this invention, a description thereof is not necessary to be herein particularly given.
My inventi on is operated as follows: The bushing to be used is placed in the bung-openin g,
and the core inserted within the orifice in the I bush, which brings the circumference of the facing in contact with the inner surface of the bushing. Power is then applied to the oppo site end of the shank, causing the core proper to revolve, and,by the frictional contact of the facing against the inner surface of the bush, the facing is secured in a fixed position, and allowing the base 0 a slight independent movement, bringing the greater diameter orare portion of the base against the inner surface of the adjacent section, imparting to the same a slight outward movement, thereby compressing the circumference of the facing against the inner surface of the bush, increasingthe frictional contact sufficicnt to overbalanee the resistance of the wood against the outer surface or threaded portion of the bush, and thereby causing the bush to revolve jointly with the core, by which means the same is turned into place.
The objects of this arrangement of the base and its corresponding sections of the facing are several: First, it enables the bushing to be turned into place without assuming an oblique position within the bung-opening; second, the separate sections are uniformly adjusted by the enlarged portion of the base, thereby producing a uniform strain upon all parts of the bush, which prevents the same from becoming elongated or irregular in shape, as would be the case if the sections engaged the two alternate sides of the bush only; third, by slightly curving the separate sides of the base, the same result is produced by turning the core in either directionthat is to say, the sections are ad justedthereby adapting the wrench to the use of turning the bush into or out of place.
I do not claim a sectional core made in two parts only, and so arranged as to bear against the two opposite sides of the bush only, for I am aware that such is not new.
Having described my invention, I claim- The wrench herein described, consisting of the shank A and core B, provided with the base 0, having a series of irregular surfaces, adapted to bear against corresponding sections 1+], whereby the separate sections are adjusted outward uniformly from the center and against all parts of the bush, as specified.
GEORGE B. OORXELL.
