UNITED STATES PATENT OFFICE.
WILLIAM TUCKER, OF BLACKSTONE, MASSACHUSETTS.
METHOD OF SECURING BITS IN THE STOCK.
Speceation of Letters Patent No. 23,326, dated March 22, 1859.
To all whom 'it may concern:
Be it known that I, IVILLIAM TUCKER, of Blackstone, in the county of lorcester and State of Massachusetts, have invented an Improvement in Fastenings for Bit-Stocks or Auger-Handles; and I do hereby declare that the same is fully described and represented inthe following specification and the accompanying drawings, of which- Figure I, is a side elevation of a bit-stock socket having my improvement applied to it. Fig. Q, is a longitudinal section of the same. Fig. 3, is an underside view of it.
The nature of my invention consists in a peculiar application and arrangement of a screw and a segmental head or its equivalent with reference to the bit-stock socket and for the purpose of enabling a person to fix or hold a boring or other tool therein.
In the drawings A, exhibits the socket head or part of a bit-stock which not only receives the tapering part a, of a bit or tool B, but projects from the bell crank of the stock, a portion of such crank being shown at b.
Extending down through the head A, and along side of the socket c, thereof, I arrange a female screw cl, into which a male screw e, provided with a milled head f, is to be screwed, and so as to project from each end of the said head A, as shown in the drawings. On the lower end of the male screw, a button or segmental conica-l frustum g, is afxed so as to rotate with the screw. The curved part of the periphery of the button projects farther from the axis 0f the screw than the chord or straight portion of it, the same being for the purpose of enabling the curved part to enter an angular notch L, made in the bit or boring tool while the male screw is being revolved. By turning the screw, the button will enter the said notch and be drawn upward so as to act against the upper part of the notch and draw the bit or tool close up into the socket c, and there hold it until the screw is turned backward, so as to carry thebutton out of the notch.
This simple invention admits of a bit or boring tool being fastened in the socket of its stock or handle with great facility and security.
I claim* The application or arrangement of the my signature.
IVILLIAM TUCKER. Witnesses TI-Ios. R. THETTEPLAGE, EDWIN NoRTHRoP.
