OF FOSTER, OHIO.
ADJUSTABLE EXTENSION-BIT HOLDER.
specification of Letters Ififettent.v
Patented -May 28, 1907.
Application filed January 12, 1907. Serial No- 351,948.
To all whom it may concern.-
Be it known that I, CHARLES E. HILL, a
States, residing at Foster, in the county of Warren and State of Ohio, have invented certain new and useful Improvements in Extension Shanks for Auger-Bits, of which the following is a specification.
This invention is an extension-shank for auger-bits and the like, to enable the bit to be used in places which would otherwise be inaccessible.
The object of the invention is to provide an extension-shank having a wide range of adjustment, and which can be attached to any ordinary bit-brace. 4
In the accompanying drawing, Figure 1 is an elevation of a portion of the extensionshank showing its parts separate. Figs. 2 and 3 are elevations of the complete shank taken from difierent sides and showing it extended to its full limit. Fig. 4 is an elevation showing the shank closed.
Referring specifically to the drawing, the
extension-shank is in two telescoping sections indicated at D and J, respectively. The former is a tube and the latter is a stem, which is slidably mounted in the tube. The outer end of the stem has a tang S for attachment to a brace. To the ends of the tube D are brazed or otherwise secured collars C and respectively. The collar O projects beyond the end of the tube and has a threaded bore into which the threaded stem B- of a chuck A screws. The chuck receives the auger-bit, screw-driver, or other tool. Any
other suitable tool-holder may be fitted to the collar.
The stem J has a longitudinal groove H, and the tube D has a longitudinal slot E. A
. set screw G is tapped through the collar and the tube D and seats in the groove H. Another set-screw F passes through the slot E and is tapped tube D.
Upon loosening the set-screws F and G, the stem J is free to'slide back and forth in the tube D and the desired adjustment can be made, after which the set-screws will be tightened which will securely hold the parts in adjusted position .vith no danger of side play or wabbling. a
The extender will be found useful in places that cannot be reached by an ordinary bit, and when not in] use it can be closed up into a small and compact form as shown in Fig; 4 for convenience in carrying it.
I claim 1. An extension-shank for bits and the like comprising a longitudinally slotted tube into the stem J within the having at one end tool-holding means and open at the other end, a longitudinally grooved stem entering the open end of the tube and slidable therein, a set-screw tapped through the tube and seating in the groove and a' set-screw carried by the stem and working in the slot of the tube.
2. An extension-shank for bits and the like comprising a tube open at one end, a collar fixed to the opposite end of the tube and projecting therefrom, and having a threaded bore to receive a tool-holder, a stem entering the open end of the tube and slidable therein, and means for holding the tube and'stem at adjustment.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
I CHARLES E. HILL. Witnesses L. F. DAKIN, W, CHEsTEn LIAI'LE.
