IMPROVEMENT IN BlT-STOCKS.
specification forming part of Letters Patent No. 139,667, dated`` June 10, 1873; application filed April 30, 1873.
To all 'whom it may concer'n:
Be it known that I, ALBERT D. GooDELL, of Miller's Falls, in the county of Franklin and State of Massachusetts, have invented certaincombination, and arrangement of parts, which have for their object to allow of the instrument held in the tool-holder being rotat-ed by imparting a reciprocating or semi-rotary motion to the holder, as will be fully set forth hereafter.
The several figures represent the upper portion of the grasping mechanisrn of a bit-stock or tool-holder.
Figure 1 shows the device in one position; Figs. 2 and 3, in two other posit-ions. Fig. 4 is a Vertical transverse section of Fig. 1 taken through its axis, and Fig. 5 represents a part in detail.
In boring holes or driving screws in situations where the tool-holder cannot be completely rotated considerable trouble has been experienoed, and where the hole is being bored in such close proximity to a wall or other obstruction that the crank cannot be entirely re- .volved, the holder either has to be alternately detached from the tool and replaced again a-t each reciprocation, causing great' inconvenience and loss of time, or the hole has to be bored obliquely into the wood.
To obviate this difiiculty several devices have been employed, as ratchet-drills, universal-jointed tool-holders, &c., all ot' which were more or less unhandy, complicated, and expensive, and my invention is designed to obviate this, as follows:
A represents a part of the crank-handle of a tool-holder, the lower extremity of which is lfornied into a solid cylinder or hub, B. O is a portion of the socket of the holder, in which the graspin g j aws (not shown in the drawings) work, and, instead of being, as usual, stationary in relation to the crank-handles, this socket is capable of revolving oni the hub B, it being held thereon by a pin, h, which passestangentially through its sides and fits in the groove f cut in the periphery of the projection on the hub B. At equal distances apart, on the upper edge of the socket U, square. slots or recesses e e are cut, and in the cylinder B, parallel with its axis, a chamber is drilled for the reception of the latch b. This latch is forced outward against the upper edge of the socket: (J by the spring c, and as the socket is revolved the latch enters the recesses or slots e in succession. d is a handle, which enters the latch-Chamber by a hole through its top, and is secured to the head of the latch. By this handle d the latch may be adjustcd so as to revolve the boring-tool in either direction, as
is shown by the arrows inlFigs. 1 and 3, or it square end b' prevents its rotatin g therein, and f to change its position it is necessary to withdraw it and then alter its position.
I am aware that reversible tool-holders provided with a ratchet-and-pawl arrangelnent are not new, and Ilayno claim to such, broadly but I claim- The combination, with a tool-holder, of a series of ratchets or recesses, e e,`and a pawl i or latch, b, so constructed that the tool can be rotated in either direction` and locked stationary to the handle'by the same pawl or latch,
substantially in the manner and for the purpoi ses described. p
