1 Claim.

My invention relates to mechanics hand tools, and includes among its objects and advantages an extension in. the range of usefulness of the type of tool commonly referred to as pliers.

5 In the accompanying drawing? Fig. l is a side elevation of a tool according to the invention, illustrating the additional use for which it has been adapted.

Fig. 2 is a partial section on line 2-2 of Fig. 1.

In the embodiment of'the invention selected for illustration, the pliers comprise 'the usual arms and 12 connected by a pivot 14, which pivot is carried by the arm 12 and may be received in the socket 16 or in the socket 18 of the arm 10.

The rear end of the arm 12 is flattened and spread out slightly to form an abutment 22 having an outwardly concave rear edge at 24. The rear end of the arm 10 is formed into a cylindrical pin 26 extending substantially at right angles to the arm as a whole, and approximately in alignment with the center of the concave edge 24.

In various manipulations of machinery, it frequently happens that a plate such as 28 aperturedv at 30 to receive a bolt or pin 32, which may or may not be threaded, does not fit very precisely or the bolt 32 is not in perfect alignment, and considerable difiiculty is experienced in getting 30 the end of the bolt entered in the opening 30. This is especially true when the plate and bolt are adjacent the sides of some other machine element indicated at 34, such as the leaves of an automobile spring. Under such circumstances, if

35 the bolt 32 happens to be too close to the member 34, there is little or no difliculty, as an ordinary screw driver can be wedged between the bolt 32 and the element 34 to spring it out into 0 alignment. However, the usual difliculty is that The arms carry the usual gripping jaws 20.

the bolt 32 is toofar from the eminent 34, and it is very difiicult and awkward to find a fulcrum or purchase point to enable the mechanic to push against the bolt 32 with sufiicient force, and at the same time driverit up or drive the plate 28 down to complete the assembly.

As clearly indicated in Fig. l, the entry of the PATENT} OFFICE hook, or pin, 26 into the opening 30 with the abutment 22 pressing against the side. of the bolt 32 affords not only an immediate and certain fulcrum, but an excellentleverage so that a slight force will spring the bolt into, line and complete the assembly. 6 i

Additional convenience may result if the arms are so shaped that with the pivot 14 entered in one of the sockets 16 or 18, and the jaws 20 closed, the pin 26 and abutment 22 are spaced apart by substantially the distance necessary for getting a good leverage on the parts to be assembled. I have illustrated a pair of pliers inwhich this positioning occurs when the pivot is in the socket 18.

Without further elaboration,-the foregoing will so completely explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service. i

I claim: 2

A pair of short-jawed pliers, one of the handle ends of which'terminates in a cylindrical plug substantially normal to the axial line of the handle, and the other end of which, when the pliers are closed, is spaced from the end of the plug, the outer end of this last mentioned handle portion having a concave recess axially'flattened to adapt it to bear against screw threads without injury to such threads.v p Y a J.
