Description
UNITED STATES ATnNT @Trione GROMWELL O. RIGHEY, 0F AURORA, INDIANA.
IMPROVEMENT IN BRACES FOR BITS.
Specification forming part of Letters Patent No. 55,36, dated June 5, 1866; antedated May 16, 1866.
To all whom fit may concern Be it known that I, CROMWELL 0. RIGHEY, of Aurora, Dearborn county, and State of lndiana, have invented a new and useful Improvemen t in Brace-Fastenings for Bits, of Which the following is a full and clear description thereof, reference being had to the accompanyin g drawings, forming part of this specication.
My improvement embodies a nes7 device by means of which a bit may be firmly secured iu or readily removed from the brace.
Figure l represents a brace and bit with my improvement attached. Fig. 2 is an enlarged viewr of the neck of a brace and shank of a bit, the bit being' removed from the brace. Fig. 3 is a perspective view of the neck of a brace as seen from beneath, showing several features of my improvement. Fig. 4 is a perspective view of a notched retaining-bar, which forms a part of my improvement.
' A is the body of a brace. B is abit, from the shank of which projects the pin b. C isa slot in the neck of bit A, which does not penetrate through to the cavity of the neck till near its lower end at the point o. A short distance from the extreme end ofthe neck ot' the brace is the recess c, which opens into slot C, and is for the purpose ot' admitting the pin b. D is a retaining-bar playing in slot G. The upper end ot' the retaining-bar D has a cylindrical projection, d, which passes through the upper part of neck D, and is pressed upon by spring E, which is secured to the brace. A projection from the back part of the retaining-bar at e is of equal depth to thickness ofthe bridge of slot C, as shown at point o. fand g are offsets from the front part of the retaining-bar, and check its motion in opposite directions. c is a depression in the neck D, which receives the ferrule 7c.
Operation: Introduce the shank of the bit into the cavityin the neck of the bracein such a manner that the pin 'b shall pass up the slot C, the retaining-bar D having' been drawn up to a sufficient height as will enable the pin b to enter the recess o at the time the 'bit is rotated. The hand is then removed from the knob h upon retaining-bar D, when the spring E forces down the bar D` so that the eXtreme end shall till that part of slot C beneath the ferrule 7c, thus clieotually securing the bit B to the brace A. In liberating the bit draw upon the retaining-bar D, pressing back the spring E unt-il the offset g comes 'in contact with point c. The bit B may then be rotated until the pin b is passed into slot C, when thev bit may be withdrawn.
' The simplicity of this operation economizes much in the use of the tool.
Having described the construction of my iinproved brace-fastening for bits and the use of' its various parts, I make the following claim:
The retaining-bar D, spring E, ferrule 7c, and slot G, in combination with bit B andufpin b, arranged as above described, and for the purposeset forth.
CROMWELL 0. RIOHEY.
