UNITED" STATES 1,497,969 PATENT oar-ice.

WILLIAM E. ARBOGAST, OF DUNMORE, WEST VIRGINIA, ASSIGNOB TO WINFRED MOELWEE, OF DUNKO'BE, WEST VIRGINIA.

runes Application filed liovembere, 1922. Serial 110. 598,401.

To all whom it may conaem:

Be it known that 1, WILLIAM H. Anaoeas'r, a citizen of the United States, residing at Dunmore in the county of Pocahontas and State of West Virginia, have invented cer tain new and useful Improvements in Pliers, of which the following is a specification.

The present invention relates to improvements in tools and in particular to that type of implements known as pliers.

The rimary object in view is to provide a novel arrangement of the gripping jaws of the pliers such that for a given size an increased capacity and gripping power is secured as compared with the usual type of pliers in which the jaws form integral extensions of the handle members.

To this end the invention comprises crossed handle members, one of which is provided with an integral jaw and a relatively movable jaw, to the latter of which the other handle member is pivotally connected at a point intermediate the ends of the jaw, the last mentioned handle member having a sliding or slip-connection with a fulcrum upon its cooperating handle memher by means of which the variation in the leverage action upon the movable jaw is ohtainable.

With the above and other objects in view, the invention consists in certain combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

Reference will now be had to the accompanying drawing forming a part ofthe specification, wherein:

Figure 1 is a front elevation of a pair of pliers constructed in accordance with this invention, showing the jaws in their closed position.

Fi re 2 is a view similar to Figure 1, showing the jaws in their maximum opened position.

Figure 3 is a fragmentary sectional view taken on the plane indicated by the line 33 of Figure 1.

Figure 4 is an enlarged side elevation of the aw extremity of the pliers, showing the formation of the movable jaw more particularly.

Corresponding and like parts are referred to in the following description and indicated in all of the views of the drawing, by like reference characters.

Referrin to the drawing, 1 indicates what for t e purpose of this description I term the relatively stationary handle mem- 'ber which is formed at its extremity with an integral relatively stationary nose or jaw member 2, the particular configuration of which is immaterial so far as the present invention is concerned. At a point approximate the base of the jaw 2 the handle member 1 is recessed from opposite sides as indicated at 3 to receive the bifurcated end of a relatively movable jaw 4 which is pivotally secured to the handle member 1 by the pivot 5. The jaw4 is given a configuration corresponding to that of the jaw 2, the inner surfaces of the jaw members illustrated being suitably corrugated to increase their gripping action as is customary in pliers of this character.

A relatively movable handle member 6 is slotted for a substantial distance from one end so as to straddle or receive the handle member 1 and this handle member and the handle member 6 referred to, are obviously connected to the movable jaw 4 at a point intermediate the length of the jaw as indicated'at 7, the opposite sides of the bandle member 6 being formed with closed slots 8 to receive the fulcrum projections 9 of the handle member 1.

It will be observed by reference to Figures 1 and 2 that the connection between the two handle members 1 and 6, is a shiftable connection. That is to say, in the opening and closing movement of the jaw 4, through the operation of the handle 6, a sliding movement of the handle 6 with respect to the handle 1 takes place. As the jaw 4 is opened the fulcrum shifts toward the upper end of the slots 8, thereby, increasing the leverage of the handle 6 to a material extent so that the pliers of this construction obviously have a greater gripping action as the jaws are positioned in a more open relationship. Moreover, by this arrangement the jaws have a greater opening 4 movement for a given size, increasing the gripping action is produced by pressure u on the handles, the jaw 4 moves about its lar objects havin p1vot 5 and tends to impart to the object bemg grippeda slight rotation. This is especially useful, therefore, in connection with the removal or application of nuts or simiscrew-threaded attachment with other 0 jects.

Having thus described my invention,what I claim as new and desire to secure by Letters Patent, is:

1. A pair of pliers comprising crossed handle members, one of which is provided with a relatively stationary jaw and a movable jaw, the other handle member having a sliding pivotal mounting upon the stationary jaw and a pivotal connection with the movable jaw at a point spaced from its pivot connection with the first mentioned handle member. 7

2. A pair of pliers comprising crossed handle members, one of which is provided with a relatively stationary jaw and a movable jaw, the other handle'member having pivotal connection with the movable jaw at a point spaced from its pivot connection with the first mentioned handle member, and a fulcrum on the first mentioned handle member cooperating with an elongated slot in its cooperating handle member.

3. A pair of pliers comprising crossed handle members, one of which is provided with a relatively stationaryjaw, a movable aw pivotal] connected thereto, the :other andle m'em er having a slip fulcrum connection with the first mentioned handle member capable of longitudinal movement thereon and pivotal connection with the movable jaw.

4. A pair of pliers comprising crossed handle members, one of said handle members being provided with fulcrum points with which the other handle member has shlftable connection, a relatively stationary jaw on one of said handle members, and a movable jaw pivoted thereto, the-other handle member having a pivot connection to the movable jaw at a point intermediate its length.

5. 'A pair of pliers comprising a pair of crossed handle members, one of said handle members having an inte' ral jaw at one end, the other of said han le members being slotted lon itudinally to receive therebetween the rst handle member and being provided with diametrically opposite closed slots receiving fulcrum points extending from the first handle member, and a movable jaw pivotally secured to the first handle member and having connection with the In testimony whereof I afiix my signature.

WILLIAM H. ARBOGAST.
