Application filed october 12.1925,- Serel: No, @4193i Be it known that I, Knew E. NORDIN, a citizen. of the United? States, residing at Bergland, in the Province of. Ontario and Dominion ofCanada, have invented certain new and usefulImproaelnents Pliers, of which the following isa speciiicatiOn.

invention relates` to improvements in pliers, and has for its principal object to provide atool of the above mentioned character. whieliisof such construction as to enable greater pressure to be applied; on the eoacting jaws in order to facilitate the turn-v ing. o-fftlaeobjectwhich is clampedtbetween the jaws'. i

A furtherobject is toV provide a tool` of the above mentioned: character whiclai will not defaeethe object. whichis4 to tnlnedwhen. a great. amount oftf` pressure isk applied. such as frequently happens with thetyfpe ofV pliers nowfgfeneralfly inuser Another important object is to provide toolofftheabone mentioned character which is simple in construction, inexpensive, and furthermore adapted to the purposes for which the same is designed.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a view partly in elevation and partly in section of my improved pliers;y

Fig. 2 is an edge elevation, and

Fig. 3 is a transverse section takenV approximately on line 3-3 of Fig. l.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates an elongated handle on the forward end of which is formed the stationary avv 2. 1

Cooperating with the stationary jaw 2 is the coacting movable jaw 8, the same being pivotally associated with the stationary jaw as at L1. The inner opposed faces of the jaws are provided with the cooperating' cut-out portions 5 ando to facilitate the gripping of the nut or any other Object which is to be turned and the inner opposed faces of the jaws are also provided with the coacting eutting edges 7 and 8 respectively, the same being pivotally formed and attached forwardly of the pivotal connection 4a i A tail piece or extension 9.. is. formed Q11 the rear endet' the inovablejaw 3,the saine tapering gradually toward ther rearend.. @his tail, piece or extension is bifurcated as indicated at 10, and theends of the furca- 6DA tions are beveled as illustrated at 11 fortlie purpose hereinafter to bev lmore fully described. K

Coacting. with, the elongated handlelV is the oper-ating lever 152, the. forward en -d of 65. which is enlarged asA indicated at.; A11 enlargement 14 is formed onk the inner side edgeof-,the handle 1vadjacentv the forward end: thereof andths enlargement le' iS Prof vided wit-1i eL transversely estellduaeloove 70 15, the sainebeing adapted to receive the tongue liwhieh entends laterally frein the innerside edge kof .the en larged forward endl 13- of the; lever 12 whereby pivotal con;y n ection between the operating lever andthe intermediate portion of the handle pro-fvidedA Y The forward end of the enlarged portion 18 of the operating lever 12 is reduced as illustrated at 17, the reduced portion being adapted to be disposed between the furcations formed by the slot 10 provided in the tail piece 9 of the pivoted'jaw 3i. The outer edge of the cut-away portion 17 is provided withthe shoulder 18, the same being adapted to engage the outer side faces of the furcations 19 whereby the extension 9 or tail piece formedthereon on the pivoted end of the jaw 3 will be pulled inwardly toward the handle 1 so that the forward end of the pivoted jaw will be moved outwardly away from the stationary jaw so thaty the pliers will be opened, it being understood that when the free end of the lever 12 is swung upwardly, the forward end of the lever and the tail piece will move inwardly, the tongue 16 and the groove with 'which the same is disposed acting as a fulcrum for the lever and when the tail piece is swung to its innermost position, the beveled spacers 11 will engage the inner side 6 of the adjacent portion of the handle 1.

Laterally positioned yportions 20 are formed on the forward end of the reduced portion 17 adjacent the inner side edge thereof and these .lateral projections cooperate with the inner side faces of the furcations 19 for moving the tail piece of the pivoted jaw outwardly whereby the jaw 3 is swung on its pivot f1 inwardly to a coacting relation with respect. to the stationary jaw 2 so that the object to be turned will be clamped between the jaws. It is obvious that by moving the tree end of the lever forwardly across the free end or the handle 1, greater pressure will be exerted on the pivoted jaw 3 so as to enable the nut to be more easily and readily loosened or tightened as the case may be without detacing the nut.

A punch 21 is formed in the tree end of the handle l for use in forming eyelets in belting or the like and through which lacing is adapted to extend. An outlet 22 is provided for the particles of leather' which have been removed from the belting by the punch 21. as clearly illustrated in Fig. l.

The simplicity in which my improved pliers is constructed, enables the same to be readily assembled and the parts will at all times be positive and eticient in their operation. The cutting edges 7 and 8 permit the tool to be used as a cutting implement whenever necessary thus obviating the necessity of having `to use an independent tool for cutting purposes.

While I have shown the'preterred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit or sacrilicing any of the advantages of the appended claim.

Having thus described my invention, what I claim as new is A tool of the class described comprising -an elongated handle, a stationary jaw formed on the forward end thereof, a coacting jaw pivotally associated with the stationary jaw, a tail piece formed on the rear end of the pivoted jaw, said tail piece being biturcated, a lever, means for pivotally connecting the forward portion ot' said lever to the intermediate portion of said handle, the 'forward end of said lever being reduced, said reduced portion being disposed within said bifurcation formed in the tail piece of the pivoted aw, should-ers formed on the reduced portion ot the lever adjacent the outer side thereot` for cooperation with the outer side faces of the urcations of said tail piece Ytor eifecting the inward swinging movement of the tail piece when the lever is swung outwardly, and lateral projections formed en the reduced portion of the lever adjacent the inner side thereof and adapted for engagement with the inner side -faces of the turcations to effect the outward swinging movement of the tail piece and the simultaneous inward swinging movement of the pivoted jaw into coacting relation with the stationary aw when the lever is swung inwardly.

In testimony whereof I aiiX my signature.

KNUTE E. NORDIN.
