To all whom it may concern:

. hers or any undesirable movement of her 28th,1915,

Be it known that 1, JOHN GUTHBERT, a citizen of the United States, residing at Chicago, .in the county of Cook and State of Illinois, have invented certain newand useful Improvements in VjVire Coiling and Binding Clamps, of which the following is a specification.

My invention relates to wire coiling and binding clamps, which may serve as termii allls for electric translating devices, and the One of the objects of my invention is to provide improved means for coiling a wire around the shank of a screw-threaded memher,

the wire end within a prescribed annular zone to prevent any lateral or radial movement thereof away from its clamping merlrllt e wire 1 toward the threaded shank or stud when said means is being rotated to coil and clamp thewire.

In my Patent No. 1,166,114: datedDec'em- I have disclosed one form of the device in whichthe relatively stationary member is shown to be provided with a stop, such as a slot or stud for holding the wire to be coiledaround the shank of the clamping means, to prevent it frommoving laterally or radially awayfrom the shank and from under the rotating clamping member during clamping operation, and in my application Serial "No. 64,635 filed December 2, 1915, I have disclosed a structure wherein the stationary clamping member is provided with a recess "within which to receive the screw head and to prevent lateral displacement ofthe wire from under the screw. head. 4

In my present invention 1 have provided means for bending the Wire on a longer radius than heforeand a guide and guard whereby the end of the wire is bent into an eye of predetermined size and held in a plane concentric with the shank and prevented from moving laterally from between the clamping members.

Other, further and more specific objects of my invent on will ,become readily apparent, to persons skilled in a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a central vertical section of such for instance as a screw, stud or' the like, and to thereafter clamp and hold guided while the art, from my improved wire coiling and clamping device, showing the wire inserted in place prior to the coiling and clamping operation.

- 10 is a base, or relatively stationary clamping member of the device, screw vthreaded for the screw shank 11 of the screw 12. 'The base is provided with a perforation 13 through which to pass the wire 14; the wire is shown to enter theperfo'ra tion 13, in the base 10, at an angle to'fthe perpendicular and to then extend-in a vertical direction under'the screw-head- 15. The

perforation 13 could as well extend-parallel with .the shank 11 .theentire distance through the base, if desired. It is advantageous, many times, laterally deflected, as shown, board blocks orother such fixtures.

The screw headis provided,-on its under to have the perforation as in 'panelsurface, with an annular wire guard and guldlnggroove 16, shown more clearly in Fig. 3, inter-spaced between an annular shoulder 17, near the shank of the screw,

and an outlying annular shoulder 18, radially beyond the groove. Between these shoulders and within the'groove the wire is being coiled and within which the coiled end or eye ofTthe-wire is to be retained.

screw head may 19 and removedto provide wire engaging shoulders 20, 20, respectively. The perfo- .The-'head of the screw is perforated with an elongated slot, as at 19, or a'part of the' be entirely cut: away as at to a horizontal plane, to prevent shearing of the wire when the screw is turned.

Another object of under cutting the shoul:

der, as at 21, to inclineit is to cause the wire to be correspondingly inclined so, as to pref.

V sent a relatively larger contacting sari-ace of the shoulder with the wire. to lilolfeeasily bend t e into an annu ar eye. without cutting or abrading it. The inclined surface also serves as a guide for directing the wire into the opening before the shoulder, from the perforation below.

The t m part 21, of the shoulder 20, leads into the annular wire guiding groove 16 made in the underside of the head of the screw, so as to bend an eye in the wire of diameter predetermined by the size of the *groove and to prevent the wire from being h s drawn into too close or intimate contact with the threaded shank 11 of the screw during coiling operation. After the wire enters the groove 16, as the screw is turned clockwise, the. shoulder 17 maintains the wire within the groove and determines the size of the eye to be formed in the end of the wire and the. annular shoulder 18 prevents the wire eve from leavino the roove.

upon the upper In.the use of the device the wire 14 is inserted in the perforation 13, provided in the base '10,.as shown in Fig. 1, until the end 14 of. the wire extends above the head of the screw sufliciently to. provide a suitable length .of wire of whiclrto make the eye, as shown inFig 6. The screw is then rotated. whereortion oi the shoulder 20 near the top 0 I, the screw head will be brought intocontact with the vertically extending wire, and further rotation of the screw will bend it forwardly so as to sub- .stantially correspond with the inclination .of the shoulder, as at21. As the screw is further turned the groove 16 will over-ride I the curved portion of the wire 14 and guide the wire,iwhile the shoulder 17, a result of the groove, will prevent the. wire from hug- 111g too closely to the shank 11 of the screw.

. i fter the screw has been rotated one complete revolution, the wire will thereby have,

been bent into an eye, the diameter ofwhich is determined by the roove 16.

The screw may now e further turned until the head 15 clamps the wire eye 14 in the groove 16, in contact with the base 10. When this is -done, as shown in Figs. 4 and 7, the wire cannot escape from under the head of the screw being encompassed by shoulder 18. A groove 16, substantially the same as the groove 16 in the head of the screw, may be made in the base 10, within which to receive the eye of the wire or a more shallow groove may be madein each of the clamping members, the head and in the base, as shown in Fig. 7, between which to retain the eye of the wire. v

In forming the eye in the end of the wire, in the mannl heretofore described,the re- SiliQllQV of the wire will, to some extent, rethin the screw in the position in which it has been placed in the act of clamping the wire by the friction thus produced serving to prevent its being rotated in the opposite direction to loosen the clamping screw.

To prevent the wire 14 from making too sharp a curve or turn, at the upper termination of the perforation 13, it is well to counter sink the terminal of said perforation, as shown at 25, in Figs. 4 and 6, thereby chainfering the edge of the perforation and removing the sharp corners.

lVhile I have herein shown a wire 14, and referred to it as such, it is not necessarily a solid wire, as a stranded cable may be operated upon in the same manner and clamped by the same instrumentalities as the wire, and while I have shown the preferred form of my invention it will be evident to persons skilled in the art, that it is susceptible of many modifications, not necessary to be shown, but within the scope of the appended claims.

Having described my invention, what I claim is:

A wire coiling and binding clamp comprising a relatively stationary clamping member and a rotatable screw-threaded clamping ,member. the latter having a part to engageIa wire to bend it into an eye about a shank around the axis of which said members are relatively rotatable and a wire guide for determining the size of the eye.
