Specification of Letters Patent. P t t 391,1; 14,, 192

Application filed December 12, 1918, Serial No. 266,469. Renewed April 10, 1920. Serial No. 373,016.

To all whom it may concern Be it known that I, JOHN E. HULTBERG, a citizen of the United States, residing at 127 Pa. Ave. west, l/Varren, in the county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Tool-Handles; and I do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tool handles and more particularly to those of the type known as bit drivers, in which the handle is provided with a usually tapered socket receiving the correspondingly tapered butt of the bit, which hit may be in the form of a screw driver, chisel, drill, etc. It has been the common practice to employ a slot in the socket and a wedge for reception in the slot to remove the bit from the socket, but this arrangement is more or less undesirable, due to the liability of misplacing the wedge. Attempts have been made to provide other ejecting means for the bit, but for numerous reasons they have proven ineffective or undesirable. It is the object of my invention to provide a simple and inexpensive device confined totally in the tool handle for removing the bit when required, novel provision being made for holding the ejecting device against operationwhile the tool is in use, but for permitting actuation of such ejecting device when necessary. To this end the invention resides in the novel features of construction hereinafter fully described and claimed. Figure 1 of the accompanying drawings is a side elevation of a bit driver constructed in accordance with my invention. Fig. 2 is a central longitudinal section.

Figs. 3 and 4: are transverse sections on the planes of the lines 3-3 and 44: respectively of Fig. 2.

Fig. 5 is a perspective view of the bit ejector and the means for normally holding it against operation. 7

In the drawing above briefly described, the numeral 1 designates a handle ofwood or other preferred material, said handle having on its front end a ferrule 2 which carries a bit socket 3, the bit receiving recess 4 of said socket being tapered for snug engagement with the butt 5 of the bit 6. The exterior of the socket 3 is preferably pro vided with flat surfaces 7 so that a wrench efficient and in every way desirable. though, the details shown and described are front end of said opening receiving said lug to prevent relative turning of the bit and handle.

The handle 1 is provided with a central longitudinal bore 10 opening through both of its ends and receiving a bit ejecting rod 11. The rod 11 is provided at its ifront end with a fiat head which is slidably and non-rotatably received in the rear end of the opening 8, while the rear end of said rod extends from the handle and hasv threaded thereon a nut or cap 13. When this nut or cap is tightened, the head 12 is held in contact with the front end of the I handle 1 and out of contact with the bit lug 9, but when said nut or cap is loosened as in Fig. 2 and rapped with a hammer or' the like, the rod 11 will so shift as to cause head 12 to strike the aforesaid lug 9, thereby driving the bit from the socket. Whenever-required, removal of the nut or cap 13, will permit withdrawal of the entire rod 11 through the recess 4.

By constructing the device as or substantially as shown and described, it will not only be simple and inexpensive, but highly preferably followed, it is to be understood that within the scope of the invention as claimed, considerable latitude is allowed for making numerous minor changes.

I claim:

1. In a bit driver a handle having a bit 7 receiving socket at its front end, a bit-ejecting rod slidable in said handle, said rod being rearwardly movable out of contact with the bit, means for preventing rotation of said rod and for limiting the rearward movement thereof, and a cap threaded on the rear end of said rod for contact with the rear end of said handle, to normally hold the rod at its limit of rearward movement and out of contact with the bit.

2. In a bit driver,'a handle provided with a central longitudinal bore, a socket member secured on the front end of said handle and provided in its front end with a bit receivin recess, said socket member having a flat-sic ed opening leading to the handle from said recess; the front end of said opening being adapted to receive the usual fiat lug on thebit butt, a bit-ejecting rod slid able in said bore and having a flat head occupying'the rear end 01 said opening, said head being movable rearwardly against the front end of said handle to'norm ally by said head.

In testimony whereof I have hereunto set my hand.

JOHN E. HULTBERGL
