vHENRY TOIPING, F ASHLEY, ILLINOIS.

SCREW-DRIVER ATTACHMENT.

Application filed March 3, 1925. Serial No. 12,956.

To all whom it may concern Be it known that I, HENRY To1 1 1NG,a citizen of the UnitedStates, residing at Ashley, in the countyl of Washington and State of Il Illinois, have invented certain new and useful Improvements in Screw-Driver Attachments, of which the following is a specification.

The present invention relates to wrenches, and the object is to provide a simple attachment that may be operated -by a screw driver for turning small nuts and the like, the device moreover being readily adaptable so that it can be readily produced in different sizes and shapes. v

In the accompanying drawing- Figure l 1s a view in,longitud1nal section showmg oneV of the devices engaged by av screw, driver, v Figure 2 is atop planiview of the device with the screwdriver detached,

Figure 3 is a view in elevation of the jaw' blank, indicating its formation, f

Figure 4" is a plan view of the same, Figure 5 is a view at right angles to Figvure 1, but showing the partsin separated relation. f v

In the disclosure, asuitable head 6 is provided, having atl one end suitable means for .engaging with a nut. In the form shown', thismeans consists ofan angular socket 7 'formed in said head and opening through the end thereof. The opposite end of said, head is provided with another socket8, yand in the same visitte'd-a detachable element 9 that 'has upstanding jaws 10,. forming between them a tapered socket 11. Preferably this member is vformed from ablank 12,',and

is doubled, as indicated in Figure 3, said fmember having terminal hooked portions 13 vithat overlie the endof thehead 6, as shown I; '1" 'using' tlietldevic'e, the"V .('Iiieinber 9 is' slipped into the socket 8 and ithus roduc'es a tapered seat for the reception o the bit 4l 14 of a screw driver 15. When a screw driver is thus detachably tted to the head,

.it will be evident that it may be used for turning said head, so that if a nut is engaged in the socket 7 the nut will also be M screwed uponea bolt-or other device. These structures may be of different sizes and .sha es, and the jaw members 10 may beof di erent sizes so as to fit socket heads of wrenches.

From the foregoing, it is thought' that the construction, operation and many advan-l tages of the herein described invention will be apparent to those skilled in the art, without further description, and itwill be understood that various changes in' the size, shape, proportion, and minor detailsof construction, may be resorted to without departing from the spirit o r sacricing any of the advantages of the invention. y

What I claim, is:

1. A Wrench attachment for screw drivers, comprising a substantially Vj-shaped jaw member .'forminga socket that o ens through one end andhaving flat inner aces to embrace the bit of Va screw driver and engage -the flat sides thereof, said member having its other end angular ingvcross section to be non-rotatably engaged in `the socket of a wrench head. I

f2. A Wrench lattachment for screw drivers comprising a substantially V-shaped jaw member .having fiat inner faces to embrace the bit ofa'screw driver and engage the Hat sides thereof, said 'memberfbeing angular in 9 cross section to benen-rotatably engaged in the socketof `afwrencl1l1ead, .raid jaws havingoutturned hook ortions to engage over thev end4 of the wrenc head.

In testimony whereof I aix my slgnature.

' HENRY TOPPING.
