application flleillanuary a1, 1 21. Serial No. 441,330.

This invention relates to'hand tools, and

more particularly to a' tool of this type provided with parallel operating jaws. I have chosen to show a preferred embodnnent'of my invention as applied to a tool for cr1mping metal tips upon the ends of shoe-laces,

although it will be obvious that the principles of my invention may be applied 'to similar tools usable for various purposes and provided with operatingjaws of various vide improved means for connecting the jaws of the tool to thehandles and to further provide improved means for guiding. the jaws in their operative movements so that they willbe maintained in substantial parallelism. i j

A still further object of the invention-1s to provide an improved and simple means for connecting the jaws of the tool to the handles so that they will be maintained in the proper'lateral'relation to each other;

A still further object of the invention 1s to provide jaws of a hand tool of the character described with a plurality of cooperating operatingsurfaces, which may be used for various purposes. a i

To these and other ends-the invention consists in the novel features and 'combinations of parts to be hereinafter described and claimed. a

are provided. The principles of thein'ventio'n will/be readily adaptable to working I jaws which are designed for variousxuses and are not restricted to the precise form shown.

WILLIAM A. BERNARD, OF NEW HAVEN, CoNNEc'rICUnAssIGNoR TO THE .WiLLIAM The tool shown is provided with the lever handles 10" and 11,;which areQpreferabIy made of sheet metal or the like and are U- shaped in cross-section to, provide a firm gripping surface for the hands of the operatorj These lever handles ma be knurled, as shown in Fig. 1, if desired. The

handles are bifurcated at their forward ends ,to form the forked arms 12 upon the-lever handle 10 and the forked arms 13 upon the. lever handle 11. As shown more particularly in Fig. 4, it will be seen that one of theforked portions of each of the levers is positioned between'the two forked portions of the other lever and these two lever handles are pivoted together by the pivot pin 14. A coil spring 15 is wound about the pivot pin 14 between the bifurcated portions of the lever handles and the ends of this. spring. react against .the levers so, as to urge the same to open position; The forked portions of the levers extend forwardly in advance of the pivot .14, the. two outside forked ends being so curved that the forked ends of one lever will lie in substantial verticalsalignment with the ends of theother V lever, as shown in Figs- 3, 5 and 6. v I v The jaws which I have shown connected 1 to the levers are designed for substantially parallel movement in a direction transverse to the longitudinal axis of thejtool. .These jaws are designated by thenumerals l6 and '17, respectively, andconsist of: two fiatlmembers whichare mounted for sliding move .ment on eachotherto bring their cooperat mg surfaces into working relation. The jaws are provided, respectively, with

perforations

18 and 19, through which are passed

pins

22 and 23, thus pivotally connecting the jaws to lever handles 10 and 11. As illustrated in the drawings, the

jaws

16 and 17 are extended longitudinally 'with respect to the is by providing them with cooperating slots and pins to cause them to move in substantial parallelism. While pins, other .thanthe pivot. pins may be provided upon the jaws and used for this purpose, I

have chosen to illustrate guide slots: 20 and 21, in the

jaws

16 and 17,. formed in transverse alignment with. and adapted to receive, respectively, the

pivotpins

23 and 22, each of which passesthrough, the perforation in one jaw and the slot in the other jaw, so that common means are providedgto pivot the jaws to the handles and to guide them in their movements The jaws are thus guided in substantial parallelism by the cooperating slots and pins, while the forked. ends of the levers which embrace the jawsupon each sijdexwill maintain them in; lateral contactwith each other.

Each one of the jaws is, provided at one end with a returned portion. 24-, whichis turned up to provide a seat 25, which is longitudinally directed with respect tothe axis ofthe tool, while the opposite end, of each jawisprovided with aconcave surfaced forming. edge 26 which is longitudinally directed with respect to the axis of the tool and is designed to. cooperate with the seat or socket 25. The. returned portion 24 causes the jaws to be shaped 'in the form of a J in longitudinal cross-section. Itwill, therefore-, benoted that each aw may be identical with the other in shape, location of slots and perforations,andcutting notches thereby decreasing the cost of manufacture, by requiringbut one [set of tools-for making same,

and that larger quantities may be made at one time. As shown in Fig. 5, thejaws when opened will occupy such a position relatively to each other that a substantial opening 27 will be provided above the sockets 25 to permit the insertion of the lace tip therethrough. The jaws may be provided, if desired, at thefront edges thereof, with cooperating

cutting surfaces

28 and 29, which may be used in connection with tllt-llOOl described to sever the ends .of the laces. A hookor latch 10 may be provided I to'hold the handlelevers in closed position.

In Fig. 7 is shown various steps in the operation of crimping a metal tip upon the end of a lace 81. The tips are usually sold in the form shown at 30 in this figure in which they are shown as partially rounded to presenta U-shaped cross-section.

The operation of the device is as follows: A lace is inserted within a tip, as shown in the View at the left of Fig. 7, and the lace and. tip are then inserted through the opening 27 into the socket or seat formed at the end of one of the jaws. The jaws are then brought together,,as shown. in Fig. (i, and the resulting operation will be-the turning. of the tipinto the form shown in the two views at the right of Fig.7 and the crimping or binding of the tip in this position. The socket 25 upon one of the jaws may be smaller than that providedv upon the other jaw so as to provide for the crimping of larger or smaller tips upon thelaces.

In some cases the laces will be foundto be longer than desired, and ifjthis is. true, they can-be: cut oii'tothe desired length, by the cutting jaws 28. and 29, which are pro vided at the forward facesof thetwo jaws.

While I have shown and described a preferred embodiment of my inventiomin connection with a practical use for the same, it is to be understood that the same is not limited tothe exact form and use described I againstthe action of aclam'p screw, A.

very effective and strong terminal is formed .upon; the stranded wire when this tool is used to crimp such a tip. about the strands, which obviates, due to the close electrical contact obtained,the useof solder or the like.
