SCREW-HOLDING ATTACHMENT FOR SCREW DRIVERS.

Application filed September 28, 1923. Serial No. 665,305.

To all whom it may concern:

Be is known that I, SEWELL M. LIPsooMn, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new anch taehments for screw drivers by means f which screws may be effectively held with the bit of a screw driver engaged in the kerf in the head of the screw, whereby the screw may be readily applied in places which are not readily accessible.

, The primary object of the invention is to provide a device of the above kind, which embraces the desired qualities of simplicity and durability of construction as well as efficiency in operation.

Another object of the invention is to provide an eflicient form of screw holding attachment for screw drivers which may be cheaply and easily manufactured and placed into use.

Other objects of the invention will appear as the nature of the same is better understood, and the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a side elevational view of a screw driver equipped with'a screw holding attachment constructed in accordance with the present invention.

Figure 2'is an enlarged transverse sectional view, taken substantially on the line 2-2 of Figure 1, and

Figure 3 1s a View similar to Figure 2,

taken on the line 3-3 of Figure 1.

Referring more in detail to the drawing, 5 indicates the shank of an ordinary screw driver having a handle 6 fixed upon one end thereof and flattened and tapered at its op-' posite end to provide the driving bit 7 adapted to enter the kerf in the enlarged head of a screw as at 8,

In accordance with the present invention, the holding attachment embodies a piece of springy sheet metal comprising an elongated strip or body portion 9 having one end bent or extended at right angles and provided with a longitudinal slot or bifurcated as at 10 to provide a pair of spaced parallel legs 11 between which the shank of the screw 8 may pass and upon which the head of the screw 1s adapted to rest. The intermediate portion of the body 9 and the other end of thelatter is provided with pairs of opposed lateral tongues 12 which so operate to provide clasps adapted to engage the shank 5' of the screw driver so as to hold the body 9 in position parallel with the screw driver shank and in slightly spaced relation thereto, with the bifurcated lower end of the body extending transversely beneath the bit 7 as shown in Figure 1.

The tongues 12 are pro erly curved to partially embrace the shan: 5 so that the attachment is held against accidental de tachment from the screw driver shank and is free to move longitudinally on said shank to permit positioning of the screw 8.

A washer 13 is slidably disposed upon the screw driver shank 5 beneath the clasp composed of the upper pair of tongues 12 and at a point between the two clasps, a. pin 14 is extended and fastened transversely through said shank, while'a helical compres- S1011 spring 15 encircles the shank between the pin 14: and the washer 13 for normally urging the body 9 toward the handle 6 so as to insure .the yieldable retention of the Iicre vz v 8 with its head kerf engaged by the In use, the upper end of the body 9 is curved downwardly so as to slightly compress the spring 15 and move the arms 1.1 a sufficient distance away from the end of the bit 7 for'permitting the insertion of the screw 8, between said arms 11 as shown in Figure 1, whereby the body 9 is released to permit the spring 15 to raise the same and thereby bring the head of the screw into engagement with the bit 7 with the end of the latter engaged in the kerf provided in the head of the screw. When the screw is thus held, the same may be applied in remote shrouded places or places which are not readily accessible and then screwed into place without danger of dropping the screw or losing the same.

Q13 neisnoei parting from the spirit and scope of the invention as claimed.

What I claim as new is: In combination with a screw driver hev I ing a stop member mounted upon its shaft and a spring coiled around the shaft and hearing at one end against the stop memher, a screw holder attachment comprising a strip having at its edges angularly dis- 0 posed resilient tongues, the said tongues being arranged in pairs, the members of the pairs being located opposite each other and at the opposite side edges of the strip, the pairs of tongues being spaced from each other,.the tongues adapted'to frictionally receive the shaft between them whereby the spring and the stop member is disposed in the space betweenthe pairs or" tongues, the strips being provided at its end with a pair of spaced legs which are disposed at a right angle to the plane of the strips and Which extend transversely across the end edge 0 the shaft of the screw driver When the echment is applied to the said shaft.

In testimony whereof I afiix my signa- 2e ture.
