COMBINATION-TOOL.

Specification of Letters Patent.

Patented Dec. 2,1913.

Application filed December 18, 1912. Serial No. 737,449.

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates tocompound tools of the plier type and its object is to provide an improved tool of this character having jaws with multiple working elements and means whereby said elements may be adjusted into various positions for the performance of various operations therewith.

With this object in view the invention consists of an improved construction, arrangement and combination of parts of a compound tool, which will'be hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, which form part of this specification, Figures 1 and 2 represent side elevation views of my improved combination tool, in closed and transposed positions, the jaws being exactly reversed in these two figures, Fig. 3 an en larged fragmental view of my improved tool in open position, Figs. 4, 5, 6, and 7 illustrate my improved combination tool in diftal views of the ends of the respective handle members.

In these drawings, in which similar reference characters correspond with similar parts throughout the several views, the jaw members each comprise a hub 10 having a hexagonal aperture 11 therethrough and a toothed jaw 12 formed with an arcuate recess 13, the latter comprising a gripping element. Each jaw member also comprlses a cutting blade 14 and a. wire-cutting element 15 of arcuate form. The handle members each comprise a lever 16 having a hexagonal boss 17 formed thereon and adapted to fit within the hexagonal aperture 11 of either,

of the jaw members. The bosses 17 are centrally recessed at 18 for the reception of a sleeve or, bushing 18, and a screw or pivot 19 extends through the sleeve and through the handle members and both jaw members for securing them together. It will be seen that two opposite sides of the hexagonal aperture 11 areat right angles to the clamping surface 12', while two sides of the hexagonal boss 18 are at'right angles to the length of the lever 16, and therefore, it is obvious thatthe jaws and handle members may be assembled so that the clamping surfaces 12 extend approximately in alinement with the handles 16, so as to simulate a pair of ordinary pliers, as in-Fig. 1; while if the relative positions of the jaws and handles are reversed, the elements 12 will be located between the handle members, while the cutter blades will extend forwardly of the handle members, so as to simulate a pair of ordinary nippers or pincers. as in Fi 2 and 3. It will also be seen that by shi ting the handle members in opposite directions through an angle of degrees, respectively,

from the position last described, and reversing orinverting the handle members the tool may be assembled in the position shown in Fig. 5; but it is obvious that the tool may be similarly assembled without inverting or reversing the handles.

It is sometimes desirable to grasp a screw bolt or stud which is inaccessible with a pair of ordinary pliers, but which may be easily reached and grasped by a pair of laterally inclined jaws sfich as illustrated 1n Figs. 6 and 7, wherein the members 12 and 14 are turned at an angle of approximately 60 degrees to both handle members.

' cutter blades 14 could be used as a hammer when in closed position. The jaws and cutter-blades may also be reversed, as in Fig. 7, so that a jaw and a cutter-blade may be used cooperatively with each other.

In order that the hexagonal recesses may be perfectly formed with the minimum work and expense the recess 18 is made equal to the maximum diameter of the hexagonal aperture, so that the wall of the recess 18 will not interfere with a formingtool which is inserted through the hexagprocess of manuonal aperture during the the circular recess facture. This relation of and, hexagonal aperture in each jaw also provides a seat 20 for the bushingor sleeve 18, and so, when the tool is assembled, the bushing is hidden by the other elements of the tool. Moreover, while the screw or pivot member 19 may be made of comparatively soft andtough material, the bushing 18 1 tion 19,

- may be made 16 and a tack of tempered steel, so that the minimum wear takes place between the bushings and the jaw members; and furthermore. thebushing may be removed and replaced by a new one when worn.

The aperture through one of the handle members ..is preferably circular, as illus-' trated in Fig. 9,' while the other jaw mem ber, 16, is provided with an angular. aperture 16 for the reception .ofa square section 19 of the. screw member 19. The handle member 16 is also provided with a circular recess 16 into whlch is seated an extension 21- of .the nut .21 which is in cessed polygonal bosses on their inner sides,

a pair of jaws formed with a plurality of tools and having polygonal recesses to fit over the bosses of the handles whereby they are capable of adjustment 'to various positions thereon said jaws having circular recesses in continuation of the polygonal recess, a centrally recessed circular washer seated in the circular recesses of the jaws of the tool does not and handles, a bolt passing through the recesses of the handles and the sleeve, and a nut on said bolt. v

2. An implement of the plier type comprising a air of handles provided with polygonal l iosses on their inner sides, a pair of jaws inclosed by the handles said jaws carrying, a plurality of tools and having polygonal recesses extending partway through them fitting over said polygonal bosses of the handles, and said recesses of the jaws merging into larger circular recesses in their meeting faces which register with each other forming a central cylindrical recess in the two jaws, a sleeve fitting in said recess, a securing pivotal bolt passing through the handles, their bosses, the jaws and the sleeve and a nut on said bolt.

3. An implement of the plier type comprising a pair of. handles provided with polygonal bosses on their inner sides, a pair of jaws inclosed by the handles said jaws carrying a plurality of tools and having polyg onal recesses. extending partway through them fitting over said polygonal bosses of the handles, and said recesses of thev jaws merging into larger circular recesses in their meeting faces which re 'ster with each other forming a central cy indrical recess in the two jaws, a sleeve fitting in-said recess, one of the handles having a-'+.central cylindrical recessextending through it and its boss and registering with that of the sleeve and the other handle having an angular recess through its boss and a circular re:

cess in continuation thereof throughthe handle proper, body seated in the recess of the named handle and of the washer, with an'angular extension fitting in the angular recess of the second named handle and a threaded? sion through the circular recess of said-'second handle, and a nut on said threaded extension.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
