Application April 12, 1943, Serial No. 482,745

1 Claim. (o1. 81-86) This invention relates to a plier wrench, and it is an object of the invention to provide a tool of this kind which can be employed in connection with pipes, rods or other round objects in a manner assuring a firm grip.

It is also an object of the invention to provide a tool of this kind including two jaw members one supported for endwise movement with respect to the other, and wherein a handle member is pivoted to one of the jaw members and coacts with the second jaw member in a manner to impose desired endwise movement to the movable jaw upon swinging of the pivoted handle memher A still further object of the invention is to provide a plier wrench including two jaw members, one having endwise movement with respect to the other, together with a pivoted handle member carried by one of the members and coacting with the other for imposing endwise movement to said second member, and wherein springpressed means are provided in association with the pivoted handle member to hold the same normally in a position with the jaw members at the limit of their relative movement one toward the other.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved plier wrench whereby certain important advantages are attained, as will be'hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawing,

wherein:

Figure 1 is a view in side elevation, with por- Figure 3 is a fragmentary sectional view taken substantially on the line 33 of Figure 2.

As disclosed in the accompanyin drawing, l denotes an elongated shank of a jaw member A which is provided at its outer end with a laterally extending and relatively long gripping jaw 2 which coacts with a similarly disposed gripping jaw 3 carried by the extremity of the elongated shank 4 of the second jaw member B. The shanks I and 4 are in close contactso that the jaw member B may be readily moved into open or released position and with equal facility returned to closed or gripping position with respect to the jaw member A.

The shank 4 of the member B immediately adjacent to the gripping jaw 3 thereof is provided with a rigid guide loop 5 disposed in a direction opposite to that of the gripping jaw 3 and through which the shank l of the jaw member A freely passes.

The inner face of the shank 4 of the jaw member B is provided along the upper portion thereof and from its outer or free end with the teeth 6 with which are adapted to engage the teeth I carried by the head 8 of a handle member 9. This head 8 extends between the rearwardly dis posed side plates l0 carried by the shank I of the jaw member A and pivotally held therebetween by the pin I I.

The teeth 1 of the head 8 constitute a straight rack and with the 'major portion of the rack beyond the center of the pivot pin II. The inserted end face l2 of the head 8 is arranged on a curvature concentric to the pin H and on such radius to be free of the teeth 6 of the shank 4 when the handle member 9 has been swung outwardly approximately a quarter turn to allow a quick adjustment of the jaw member A with respect to the jaw member B.

As the handle member 9 is swung inwardly toward the jaw member B, or more particularly the handle member [4 thereof, the teeth I will again mesh with the teeth 6 and force the gripping jaw 3 of the member B toward the gripping member 2 of the member A and thus assure effective gripping of the work therebetween and more particularly when such work constitutes a pipe, rod or other rounded surface.

The side plates H! are extended beyond the inner face of the shank I of the member-,B and formed to provide a guide loop l5 through which the shank 4 of the member B has endwise movement.

The outer extremity of the rounded face l2 of the head 8 has an outstanding shoulder I6 with which contacts a fiat keeper ll, the outer portion of which has its under face rounded, as at I8, to closely conform to the rounded edge face l2 of the head 8, so that the keeper ll will have a minimum of efficiency.

This keeper I 1 has its lower or inner portion received in the suitably formed socket l9 provided in the end face 20 of the shank l between the side plates l0 and the lower end of this keeper IT, at its central part, is continued by an elongated pin 2| which extends within the restricted socket 22 in the base of the socket l9.

Surrounding this pin 2| and interposed between the keeper I! and the inner end of the socket 22 is an expansible member 23, herein disclosed as a coiled spring. This spring 23 constantly urges the keeper l1 outwardly and in contact with the shoulder [6, so that normally the handle member 9 is in such position with respect to the handle member M to have the teeth 1 of the head 8 meshing with the teeth 6. However, as the handle member 9 is swung outwardly, the spring 23 will allow the keeper H to have the requisite downward or inward sliding movement.

The shank 4 of the jaw member A carries a spring-pressed ball keeper 24 which normally extends slightly beyond the inner face of the shank 4 and is adapted to be selectively received within the slight depressions or indentures 25 in the inner face of the shank l of the jaw member B, to hold the jaw members A and B against separating movement after initial or quick adjustment, thus facilitating the desired coaction of the teeth I of the handle member 9 with the teeth 6 of the shank I of thej e ber B when desired to make the further finer adjustment to effect tight clamping hold on the Work between the gripping jaws 2 and 3.

From the foregoing description it is thought to be obvious that a plier wrench constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

What is claimed is:

A plier wrench comprising two jaw members each comprising an elongated shank and a gripping jaw extending laterally from one extremity thereof, the gripping jaw of one member coacting with the gripping jaw of the other member, means for maintaining the shanks of the jaw members in superimposed relation with one of the jaw members having movement lengthwise of its shank along the other, said last shank being provided along its inner face with teeth, a handle member pivotally engaged with the outer end portion of the shank of the second jaw member, the pivoted portion of the handle member having teeth for engagement with the teeth of the shank of the first jaw member, said teeth'being substantially to one side of the pivotal connection between the handle member and its shank, the outer end face of the pivoted handle being rounded and on such radius that the said rounded face is free of the teeth of the shank of the first jaw member when the handle member is swung to a predetermined extent ir one direction, and a springpressed keeper set into a recess in that end of the shank of the second jaw member which opposes said rounded face,. the pivoted portion of the handle member at the outer extremity of the curved end face being provided with a shoulder with which the spring-pressed keeper engages.
