OHN A. STAPLES, or NEWBURGH, NEW YOR SENDING-TOOL.

. To all whom it may concern/ Be it known that I, JOHN A. STAPLES, residin at Newburgh, in the county of Orange and tate of New York, have invented certain new and useful Improvements in Bending-Tools, of which the following is a full, clear, and exact descri tion, such as will enable others skilled in t e art to which it appertains to make and use the same.

This invention relates to tools,- and is arrovision of p iers peculiarly adapted to clamp clips about wires.

. i It has for one of its objects to provide pliers characterized by increased simplicity and Another object is to provide pliers such that during the operation of clamping a clip about two or more wires relative movement or slip ing of the wires is prevented, insuring the ho ding and clam in of the same in a definite predetermine re ative position.

Another object is to provide a pair of pliers of the above type so constructed that the clip will be accurately positioned with respect to the clamping-jaws.

Another object is to provide efficient and for securing a furniturespring in operative position.

Other objects wil be in part obvious and l in part appear'hereinafter.

My invention accordingly consists in the combinations of elements, and arrangement ofparts which will be exemplified in the device hereinafter described and the scope of the a plication of' which will be indicated in t e following claims.

relates especially to pliers articularly ada ted to clamp a peculiar sty e of clip about t e upper coil of a furniture-spring and the adj acent portion of a wire to which it is desired to secure the same. I have found that duringthe clamping operation the wires have a tendency to roll or otherwise move relatively to each other, and it is highly desirable, there: fore, that means'be provided to prevent such relative or rolling movements. '1 have also found it desirable to rovide means in connection with pliers of t e above t e adapted to determine the positionof the c ip relative to the clamping-jaws of the pliers, and thus hold the same in position during the clamping operation and accurately position it upon the wires. I

The above and other defects are remedied and many positive advanta es attained in constructions of the nature 0 that hereinaf-v ter described.

Referring now to and 2 are provided with manipulating-handles 3 and 4;, respectively. The upper ends of jaws 1 and 2 are broadened and turned inwardly toward each other and are provided with spaced teeth 5 and 6, respectively, the

teeth u on each member being staggered with re erence to those upon the other and the spaces being of such width as to receive the o posing teeth when the jaws are brought toget er, as will be apparent hereinafter.

Arranged upon either side of jaws 1 and 2 and pivotally connected to each by pins 7 and 8 are lates 9 and 10, supporting a bed 11, which lies between the jaws and under Patented mw. 6,1906.

the drawings, the jaws 1 the teeth pro ecting from their-inwardlyex tending portions.

Plates

9 and 10 are carried slig 11 at either side thereof to form abutments 12 and 13, the function of which will be set forth hereinafter.

Extending from bed 11, near each end thereof, are studs 14, preferably substantially V-shaped, as shown, and adaptedto enter similarly-sha ed notches 15 in the ends of a clip 16, whic rests upon bed 11, as clearly shown in Figs. 1 and 2.

Clip 16 comprises a strip of sheet metal having a base 17, from the lateral edges of which extend at right angles thereto spaced ton ues or

flanges

18 and 19, respectlvely. In t is illustrative embodiment of my invention I preferably provide clip 16 with one straight lateral edge 20, the op osite edge being curved, as at 21, so that w tly over the upper surface of bed en the clip and the jaws 1 and 2,

with the coacting abutments,

is clamped about the upper coil of a bed or other furniture spring and the edge or binding Wirethereof the curved .edge will conform to the contour of such coil, while the straight edge will receive the wire. Clip 16 is designed to rest upon bed 11 with studs 14 occupying recesses 15, cut in the ends of said clip. Studs 14 are placed upon bed 11, so as to maintain the tongues or flanges of the clip opposite the inwardly-extendlng teeth 5 and 6, as clearly shown in Fig. 2, these tongues corresponding in number and position with the teeth with which they are to coact. Jaw 1, moreover, is slightly con veXed to receive the curved edge of clip 16, jaw 2 bein straight to receive the straight edge 20. En eXtensile spring 22 is arranged between jaws 1 and 2, adapted normally to maintain the same in an open position.

The method of use of the above-mentioned parts is substantially as follows: Clip 16 being placed upon bed 11 with studs 14 occupying the recesses 22, as hereinbefore described, the device is ready for use. The clip carried by the pliers is now placed about the wires to be clamped with the curved edge thereof adjacent the up er coil of the spring,

by means of handles 3 and 4, respectively, are forced together, teeth 5 and 6

engagin tongues

18 and 19, respectively, bending t em about the wires to clam them firmly together. The tongues of the c ip when the same is clamped about the wires fit within the similarly-shaped spaces upon the opposite sides thereof. Durin the clamping operation the tongues 18 amI 19, inasmuch as they have a greater relative movement at their upper extremities than at their bases, force the wires firmly between abutments 12 and 13 and the V- shaped studs 14, thereby preventing all relative movement or any tendency to roll one upon the other. It will accordingly be seen that I have provided a pair of pliers well adapted to achieve the objects of my invention. The position of the clip with respect to the clamping-jaws is accurately determined, and the studs, by reason of their V-shaped surfaces, together serve to maintain the wires in a fixed position during the clampin operation.

It wil be understood, of course, that the relative number of tongues upon the clip or the teeth upon the clampingaws is purely arbitrary, and a reater or less number may be em loyed wit out effecting a de arture from iihe spirit of my invention, a though there are many advantages inherent in the use of the clip shown.

As many changes could be made in the above construction and many apparently widely-different embodiments of my invention could be made Without departing from contained in the above description or shown in the accom anying drawings shall be interpreted as il ustrative and not in a limiting sense.

I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
