GUY W. FAUST, OF AUBURN, PENNSYLVANIA.

SCREW DRIVER;

Specification of Letters Patent. Pate t d 11 28 1922 Application filed December 11, 1920. Serial No. 429,933.

T 0 all whom it may concern:

.Be it known that I, GUY W. :FAUST, a citizen of the United States, residing at Auburn, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Screw Drivers, of which the following is a specification.

My present invention has reference to improvements in screwdrivers.

My object is to produce ascrew drlver which is especially designed for use upon screws that have the kerfs in the heads thereof of a special formation, and in which the walls provided thereby are so engaged by the bit of the screw driver as to permit of the driving of the screw by a torslonal force applied to the screw driver ZWIthOHt necessitating the application of direct or longitudinal pressure thereagalnst, and further wherein the screw will not be accident ally dislodged by disengagement of the screw driver.

The foregoing, and other objects which will appearas the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts, such 'as is disclosed by the drawings which accompany and which form part of this application.

In the drawings 1 Figure 1 is an elevation of a screw driver, constructed in accordance with this invention, and arranged to haveits bit engaged in the kerf of a screw for which the screw driver is especially designed.

Figure 2 is a slmilar view, but showing the bit of the driver received in the kerf of the screw and turned to engage with the walls formed by. the kerf.

Figure 3 is a sectional view on the line 3-3 of Figure 2.

' Figure 4 is a perspective view of the screw driver showing the adjustable handle on the rectangular shank thereof.

While my improved screw driver may be employed for operation upon screws having their heads formed with the usual transverse kerfs, whose side walls are straight, the improvement is especially designed for use in connection witha screw 1, such as is disclosed by the drawing. The screw 1 has its head provided with a transverse kerf 2, whose side walls are parallel and straight. The head 3 of the screw 1, below the kerf 2 has a substantially rectangular transversely arranged slot 4 with which the kerf 2 centrally communicates. v

My improved screw driver includes a handle 5 provided with a metal shank 2 that terminates in a bit 7. The shank 6 is square or rectangular in cross section. and the b1t is of a width slightly less than that of the shank, the edges of the said bit he 111g arranged at the end thereof to the shank, while the opposed faces of the bit are beveled at a more determlned angle from the shank to the end of the stud bit. This arrangement permits of the arrangement on the rectan ular shank of the socket end'8 of the handle member 9. The handle is arranged at an angle with respect to the socket, and may be used n connection with the ordinary handle 5 inturn ng the screw driver. As the handle 9 is ad ustable on the shank 6, the employment thereof will be found greatly desirable when the screw 1 is to be inserted in particularly hard wood, and also when the screw is of the machine type and is employed 1n connecting metallic plates.

The b1t 7 has its sides, ad acent its enterlng point notched, as at 10. The walls between the notches are spaced a distance from each other slightly greater than the distance between the inner wall of the transverse groove or channel 4 and the outer face of the head 3 of the screw 1. The por tion 1 1 between the notches 10 may be of a material width so as not to weaken the device at this point. The depth of the notches 10 is suliicient to )ermit of the diagonally opposed corners of the T-head provided at the bit end of the driver, contacting with the inner or side walls provided by the groove 4, and the same diagonal corners of the connecting element or shank 11 contacting with the opposed walls )rovided by the kert' 2. \Vhen the screw driver is so arranged in the head of the screw, the latter cannot be accidentally removed from the former. Also in such position a direct longitudinal force against the screw driver is not necessitated, it being merel necessary to turn the screw driver with t e screw and thus merely a torsional force is applied to the screw driver. The angularly arranged adjustable handle 9 will materially assist the operator in either driving the screw home or removing the same, and it is believed that a further description of the ima slight inclination from end portion of the shank; of a supplemental,

one-piece handle. applicable and removable over the forward end of the shank and having an angular aperture adjacent to one end directly and snugly receiving the major portion of the shank, said supplemental handle extending at right angles to the -major portion of the shank whereby the gravitational action of its opposite end wlll tend to hold it to the shank and against length thereof. In testimony whereof I afiix my signature.

GUY W. FAUST.
