LOUIS RUEGG, OF LEWISTOWN, MONTANA.

BIT-HOLDER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed April 11, 1907. Serial No- 367,668.

To all whom it may concern:

Be it known that 1', LoUIs RUEGG, a citizen of the United States, residing at Lewistown, in the county of Fergus, State of Montana, have invented certain new and useful Improvements in Bit-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

This invention relates to new and useful improve ments in drills and it has particular reference to the bit holders thereof.

In connection with a device of the above type the invention aims as a prinuiry object to provide a bit holder displaccablc from the tool socket and enacting therewith to afford a novel construction, combination and arrangement of parts.

The details of the invention will appear in the course of the following description in which reference is had to the accompanying drawings forming a part of this specification, like characters of reference designating similar parts throughout the several views wherein:

Figure l is a side elevation of drill embodying the improvement comprehended in the present invention. Fig. 2 is a central longitudinal sectional view thereof. l ig. 3 is a detailed perspective view of the bit holder detached Fig. 4 is a detailed perspective view of a bit, but employed in connection with the holder illustrated in Fig. 3, it being understood that a similarly constructed cognate tool may be employed according to the circumstances of the use, and, .Fig. 5 is a section on the line 5 5, of Fig.

Referring to the accompanying drawings the numeral 1 designates a casing having at one end a curved strap or grip 2 adapting the d vice for use as a breast drill and at its other end an annular boss 3 constituting a bearing for the end of a cylindrical drill socket i, which contrally of its journaled end has fast connection with a longitudinal shaft 5 journaled in a web 6 spanning said boss and in the opposing end of the casing 1. The shaft 5 carries a. fast bevel pinion 7, in mesh with a similar pinion 8 fast on the end of a. shaft 9 disposed at right angles to the shaft 5 and journaled in the casing 1, the shaft 9 being provided on its outer end with a crank handle, 10, by means of which the drill is manipulated.

The drill socket l is provided with an axial triangular shaped recess 11, communicating with the front end of said drill socket and terminating short of the rear end thereof. Within the recess 11 is a slidable bit holder 12 of triangular cross-sectional contour and having a suitably secured depending pin 13 extending from an apex thereof and projecting through a longitudinal slot 14 provided in said drill socket. The rear end wall of the socket 4 constitutes a stop to limit the rearward sliding movement of the bit holder 12. Said bit holder adjacent its front end has one of its sides provided with a square or rectangular recess 15 from which leads a constricted longitudinal groove 16 extending to the front end of the said socket and having a curved wall or. bearing surface. The tool illustrated in Fig. 4, comprises a working portion 17, and an axial rounded shank l8 terminating in-an enlarged flat sided head 19. The head 19 is disposed within the recess 15 and the shank 18 is disposed partially within the groove 16, the conformation of said recess 15 and head 19 preventing rotation of said tool with relation to the bit holder. The latter has its rear end curved from one side thereof as at 20 affording a cam and is provided adjacent said cam end with a recess or notch 21 having a perpendicular wall 22. Upon the outer surface of the drill socket 4 is a pawl 23 pivoted at 24 and having an angular working end 25 projected through an opening 26 in said drill socket and normally held into engagement with the wall 22 by a spring 27.

In operation, the drill is held by one hand which grasps the strap 2, and the crank handle 10 is rotated by the other hand, such rotation serving through the gears 8 and 7 to rotate the drill socket 4. and the bit holder and bit held therein. The tool is normally held from displacement by virtue of the head 19 being confined in the recess 15 by the adjacent flat side of .the recess 11. When it is desired to remove a tool for any purpose, the pawl 23 is pressed against the tensionof the spring 27 to move its end 25 out of the recess or notch 21. The bit holder 12 is thus released and may be slid outwardly by pressing upon the pin 13, the end wall of the slot 14 defining the limit of the outward movement of the bit holder. When the bit holder 12 has been thus moved in the manner described the tool may be removed therefrom and a new one inserted. In restoring the parts to their normal engaged relation the bit holder is moved inwardly, its cam edge 20cmgaging the end 25 of the pawl 23 and raising the same until said end is forced into the recess or notch 21 by the pressure of the spring 26. At which time the device is again ready for use.

A drill constructed in accordance with the present invention is simple in construction, inexpensive to manufacture and practical and ellicient in use.

From the foregoing description it will be seen that simple and ellici'ent means are provided for accomplishing the objects of the invention, but, while the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that vari ous minor changes may be made in the proportions, shape'and arrangement of the several parts, without departing from the spirit and scope of the invention as defined in the appended claims. g lVhat is claimed is:-

The combination with a casing, of a rotatable drill therefrom and a pawl pivoted upon said drill socket and having its working portion projected therethrough, said 10 bit holder being formed with a notch in one of the faces thereof and adapted to receive said pawl, and with a curved end beyond said notch In testimony whereof, Iafliix my signature, in presence of two witnesses.

, LOUIS RUEGG.
