No. 789,941.'A

UNITED STATES Patented May 1e, 1905.




SPECIFICATION forming part of Letters Patent No. 789,941, dated May 16, 1905.

Application filed August 3, 1904. Serial No. 219.289.

To all ufmm. it may concern: v

Be it known that 1, CLARENCE C. SmLEY, a ,citizen of the United States, and a resident of Perth .-\mbo v,`.\liddlesex county, N ew Jersey, have invented certain new and useful Improvements in Tools for Connrf-tiug lVire to Screws, Bolts, or the Like, of which the followingr is a speci'lication.

The object of m v invention. is to provide simple and efiicienttools, such as a screw' driver or wrench, adapted for readily winding wire around a screw, bolt-` or the like. for 'making electrical connections.

My invention comprises a tool adapted to v operate a screw, nut, bolt. or the like and provided with an extension adapted to pass along the side of' the screw or the like to engage a wire to wrap the vsame around the Shank of the screw, bolt, or the like.

2O The invention also comprises the novel dctails of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompany-A ing drawings, forming part. hereof, wherein- Figure 1 is a side elevation of a screwdriver embodying my invention. Fig. 2 is a vertical section substantially on the line 2 Q in Fig. 1. Fig. 3 is a side view of a modiiication. Fig. 4 is a similar view, partly in section, on the line t 4 in Fig. 3. Fig. 5 is a detail of a modified form of screw-driver. Fig. 6 is an end view thereof. Fig. 7 is a detail Section showing in v invention applied to 3S a wrench, taken substantially on the line 7 7 in Fig. S. Fig. 8 is an end view of Fig. 7. `ig. 9 is adetail section on the line 9 9- in Fig. 10, showing a modified form of wrench; and Fig. 10 is an end view thereof. 4 Similar numerals of reference indicate corresponding parts in the several views.

1n the drawings the numeral 1 indicates a tool,shown in Figs. l to6 in the form of a screw.- driver, which is provided with a projection or prong Ladapted to engagea wire 3 to wrap it around the shank of a screw, bolt, or the like 4. In Figs. 1 and '2 the projection or prong 2 is shown carried by a-sleeve 5, mounted to slide uponA the screw-driver 1, so that 5 the prong may-be pushed down below the screw-driver, as in Fig. 2, to engage the wire 3 or rise above the operative end of the screwdriver. vas in Fig. 1, to permit furthery use of the screw-driver in the ordinary manner. I preferably yprovide means for holding the sleeve 5 upon the screw-driver in positions set. and for this purposel have shown a spring 6 carried by the screw-driver and adapted to bear against the sleeve 5 and enter aslot 5 in the sleeve, a p in i'. carried bythe screw-driver., 6 entering the slot 5, serving to limit the sliding mov-ement ofthe sleeve upon the screwdriver and preventing independent rotation of one upon the other. l preferably form the projection or prong 2 on one side or face 65 in hook form orl recessed, as at Q, to afford a. lirm grip upon the wire.

In using m v improvement the wire 3 is placed under the head of the screwand close to the shank thereof, the sleeve 5 is pushed 7 4up along the screw-driver, and the end of the screw-d river is inserted in the slot of the screw.

The sleeve 5 is then pushed down to bring the projection or prong Q in line with the wire,

and then the sleeve, prong, and screw-driver are turned. whereupon the prong Q 'engages the wire and wraps it around or partially around the shank of the screw and the sleeve is slipped up above thc wire and the screw-head set down upon the wire hy the screw-driver 8 in the ordinary way.

Instead of the projection or prong 2 being carried by a sleeve it may be carried by a. part of a bar or wire 5c.. guided toA travel in a. slot 1 and project from an opening 1", formed 8S in the shank of the tool, as in Figs. 3 and 4.

the bar or wire 5 being shown 'bent through the slot l and down onthe other side of 'the screw-d river at 5 to keep the. bar'in position.

A raised portion 5e on the bar 5 serves to 9 permit the same to be operated by the thumb or linger. The tool in this form is operated as'described with reference to Fig. 1.

Figs. 5 and jillustrate a simple form of screw-driver capable of winding the wire around the shank of the screw, in which the screw-driver is provided with an integral or rigid projectionor prong 2, projecting below the operating or narrow end of the screwdriver. In this form the screw-driver end isl set into the slot in the screw and turned, and i provided with' a projection to engage a wire the prong engaees theivire and Wraps 1t g to bend it around'a screw or bolt, substanaround the Shana of the screw, and then a separate screw-driver may be used to complete set-ting the screwhead down upon the 1 wire.. Figs. 7 and 8 illustrate my improve-ments applied to a wrenchof the kind providedwith a socket at the end for eugaginga nut or bolt- 2 In Figs. 9 and'lO a tool of the form shown in Figs. 7 and 8 for the nut or bolt is pro vided with a prong 2, Integral with or secured to the tool and operating in manner dei tially as described.

f2. A tool for setting screws. bolts or nuts provided with a projection having a recessed side portion. toengage a wire, substantially 'is described. v i

3. A tool for setting screws, bolts or nuts provided with a movable projection adapted to be adjusted beyond the operative portion g ofvthe tool for engaging awire, substantially l l i scribed with respect to Figs. 5 and for turning the wire around the shank of the bolt.

M v improvements,l while simple in cong scribed may be varied without departing from the spirit of my invention. l

Having now described my invention, what I claim is 1. A tool 'for setting screws, bolts or nuts as described. y e

'-1. A tool for setting screws, bolts or nuts provided with a sleeve hav-ing a projection to engage a 'ire, substantially as described.

5. A tool for setting'screws, bolts or nuts provided with a longitud inall v-movable sleeve provided witha projection to engage a wire,

i said projection having a recessed face, substantially as described.

6. A tool for setting screws, bolts or nuts provided with a longitudinally-movable sleeve provided with a projection to engage a wire, and means for holding the sleeve upon the tool in positions of adjustment, substimtiallyv as described.

7. A screw-driver provided with a projection to extend beyond the operative edge and in the line of the axis of the screw- ,river to bend a wire around a shank, substa. .ially as described.

8. A screw-driver provided with a sleeve mounted to slide thereon and having a pro- `iection to pass beyond the operative end of the screw-driver to engage a wire, substantially as described.
