Application filed July 28, 1900.
.Be it known that 1, JOHN H. K'ALEY, a citiclass-of wrenches commonly known as alli- The object of the invention is to provide a simple and efiectiye construction of alligatoris quickly and readily operated to securely plied, so that all slipping of the wrench is .With the above object in view the invention consists in the novel features of conticularly pointed out inthe claims, and clearly Figure 1 is a perspective view of the wrench; Fig. 2, a side elevation with one of the walls perspective view of the wrench with the parts in detachable position.
Referring more particularly to the drawings, A designates the handle member of the wrench reduced at its inner end to form at end, with concaved shoulders C at its inner end and on each side thereof.
D designates a stationary jaw having a longitudinal slotted shank E to receive the tongue pivoted jaw, to be hereinafter described. The tongue of the handle member is positioned in said slot and pivotally secured to the stationary jaw by a pivot-pin F. The outer ends of the walls of the shank E are convexed to engage the concaved shoulders O of the handle member.
G designates the pivoted jaw, which is provided with a serrated gripping-surface and reduced to form a centrally-disposedlongitudinal tongue H, having its outer end formed concaved to receive the outer convexed end of the handle member. This tongue is in- Serial No. 25,158. (No model.)
pivotally secured therein by a pivot-pin I. The jaw G at the inner end of the tongue H is formed with the concaved shoulders J, disposed on the respective sides of the tongue,
and shank E is formed with convexed pora shoulder M. This enlargement fits into a correspondinglyshaped slot formed in jaw D at the base thereof and at the upper end of the slotted shank. This construction materially strengthens the jaws, as will be understood.
In operation the handle member is manipulated to operate the gripping-jaw .to engage or disengage the object to which the wrench is applied.
In the above description it will be seen that I have provided a very simple and efiective construction of alligator-wrench which is inexpensive to manufacture.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a wrench, the combination with a stationary jaw, of a handle member pivoted to said jaw and a movable jaw pivoted to said jaw, said movable jaw and handle member having engaging portions extending beyond their pivotal points, substantially as described.
2. A wrench comprising a stationary jaw, a handle member pivoted to said stationary jaw, and having an engaging portion extending beyond its pivotal point, and a movable jaw pivoted to said stationary jaw and having an engaging portion extending beyond its pivotal point and contacting with the engaging portion of the handle member, one of said engaging portions beingformed convexed and the other concaved, substantially as described.
3. A wrench comprising a stationary jaw having a slotted shank, a handle member having a reduced portion pivoted in said slotted shank, and a movable jaw having a reduced portion pivoted in said slotted shank, said handle member and movable jaw havingcontacting portions, substantially as described.
