A plicationtfiled October 27, 1923. Se1' ia1 ..l \Tolv 671,263.

To all whom dismay concern:

. Be it known that I, CHARLES S. OLso a citizen of the United States, residing at Duluth, in the county of S it-I Louis and Stateof Minnesota, have inventedcertain' new and useful Improvements in WVrenches, of which the following is a specification, reference beinghad therein to the accompanying drawmg.

This invention relates to wrenches and has special reference to a wire splicing.

wrench, such as used in connection with the splicing of high power electric transmission lines.

The principal object of the invention is to produce an efiicient wrench of this character which is as easy of adjustment and manipu lation as possible.

Other objects and advantages of the in vention will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and in which like reference characters indicate like parts:

Figure 1 is a side elevation of the head of one of the improved wrenches, showing the jaws thereof open for the reception of electric cables to be spliced; and

Figure 2 is a sectional view taken on the line 2-2, Figure 1, looking upwardly.

1 represents the head of the wrench, within the spaced jaws 2 and 3 of which is rotatably mounted the laterally projecting ratchet hub l of the jaw 5 of the auxiliary head, the latter comprising the two jaws 5 and 6 which are pivotally united upon the pin 7. The ratchet hub 4 is formed integral with the jaw 5, and has an open throat or mouth indicated at 8 which is elongated and the upper face of which is of double scalloped form, as clearly seen in Figure 1. This shape extends entirely through the ratchet hub and the jaw 5, while the lower face of the ratchet hub is comparatively straight, though arched upwardly as at 9, and gracefully joins the rearmost scallop of the upper surface. The hub l is held in position within the head 1 by its annular stepped shoulder 10 fitting within a registering recess in the head, and the outermost face of said hub is provided with a flange 11, fitting within a like recess 12 upon the opposite side of the head 1 and firmly united with the face of the hub by suitable screws 13, it being obvious that when the plate 11' is removed the auxiliarylieadmaybefwith i drawn laterally from the head 1."

The 'aws 5" and 6 of, the. auxi are adjustably united by .means ofthe'. bolt liary head.

lawhich is screw" threadedly mounted with-" in the jaw 5 and protrudes entirely through thejaw '6, said protruding extremity also being externally screw threaded for the re eeption of the adjusting crank 15, and where this bolt passes through the jaws 5 and 6 it is surrounded with an annular recess, indicated at 16, upon either jaw, the same be ing for the reception of the expansive spiral spring 17 which normally tends to'hold the jaws separated or open. To provide for the parallel opening and closing of these jaws, the one 6 is provided with an elongated hole 18, through which the pin 7 extends, providing not only pivotal adjustment of the jaws, but the parallel movement of same;

thus when the crank or handle nut 15 is unscrewed, the jaws 5 and 6 will open, and if the auxiliary head is in axial alignment with with the circumferential face of the ratchet hub 4; by the expansive spiral spring 20, said pawl being manipulated by the shank knob 21 protruding through an elongated slot 22 in the side of the head 1.

This pawl permits, as is evident, of the anti-clockwise rotation of the head 1, while the clockwise rotation of said head will carry with it the auxiliary head, and, if the wrench is clamped upon the sleeved cables for forming a splice, it will forcibly twist said sleeve, as shown in Figure 2, these cables being indicated at 28, and the copper sleeve at 24, this latter being common and well known in the art.

The head 1 is provided with an externally screw threaded shank 25 for the reception of any form of handle for example an internally screw threaded piece of tubing or pipe illustrated at 26, which may be of any desired length or size to act as a convenient handle, and it is well known that the copper sleeve into which the ends of the 'cables are placed is of oval or eliptical form in cross section. 7

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

A wrench of the character described having a head, an open sided hub-like saw tooth ratchet mounted within the head the hub portion of said ratchet being stepped to rotatably register with a like stepped portion in the head of the wrench, a removable holding plate on the extreme end of that portion of the hub extending into the head of the wrench, a gripping jaw formed integral with the end of the hub externally of one side of the head of the wrench, and a second ping jaws for releasing the ratchet.

In testimony whereof I hereunto afiix my 20 signature in the presence of two Witnesses. CHARLES s. OLSON.
