I-IANGER-WRENCI-I AND SPLICE-ADJUSTER.

Specification of Letters Patent.

Application filed December 18, .1911. Serial No. 666,454.

To all whom it may concern:

Be it known that I, PATRICK J. ll IURPHY, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Hanger-Wrenches and Splice-Adjusters, of which the following is a specification, refer ence being had therein to the accompanying drawing.

My invention relates to wrenches, and while it may be embodied in constructions adapted for various purposes, it is particu larly suitable for use as a hanger-wrench and splice-adjuster, for use on over-head trolley and other wiring systems.

The ob 'ects of my invention are to provide a simple, cheap and efficient device of the character referred to, which will enable one operator to perform and accom plish work which heretofore required the services of two or more; to provide a device which will clamp a span-wire into position on a hanger, or unclamp it with equal facility; which is applicable alike to hangers of the so-called top-hooking and bottom-hooking varieties; to provide a wrench which will hold a wire or the like positively, or permit of an accurate adjustment thereof in a splice-sleeve while a splice is being effected; and which will accomplish these results quickly, economically and effectively without burring, scarring, or mutilating the wire or hanger. These; and other objects of the invention will in part be clear, and in part be made apparent from the following description.

My invention consists in the novel parts, improvements, combinations and features of construction which are herein described, one embodiment of my invention being illustrated in the accompanying drawings, referred to herein and made a part hereof, the same serving in connection with the description, to explain. the principles of the invention, and wherein:

Figure 1 is a view in perspective of my improved hanger-wrench and splice-adjuster; Fig. 2 is afront elevation showing in detail the grab, and its manner of connection with the shank; Fig. 3 illustrates the use of my wrench as a splice-adjuster; Fig. a illustrates the manner of using the wrench in hooking a hanger to a span-wire; Fig. 5

shows the use of the wrench in unhooking the span-wire from the hanger; and Fig. 6

is a side elevation showing, in detail, the grab, as attached in Fig. 5, to the spanwire.

Referring specifically to the drawings, a shank '1, tapered down at one end to form a handle, has pivotally mounted at its opposite end, a grab 2. As shown in Fig. 2, the grab is provided at its upper end with loops 8, 3, between which the shank extends, the loops encircling a bolt 4:, which passes loosely through a hole in the shank. The lower end of the grab is curved and upturned as at 5, the central portion of this upturned end being provided on its upper edge with a groove (5 for a purpose to be hereinafter explained. Between this groove and the outer edges of the upturned portion of the grab are

lesser depressions

7, 7, there being one on either side of the groove. lntGI'IIlGClliL-l'G the looped and curved portions of the grab, and cut so as to be substantially inthe same plane as the upper edge of the upturned portion of the grab, are two

grooves

8, 8, one on either outer edge, for the reception of the span-wire. These grooves are preferably of smaller dimeir sional area at their outer edges than their largest interior width, and are cut into the grab at a slight angle to a line perpendicular with its face so as to insure a more positive gripping action on the span-wire.

A clevis 9, having one end formed to con stit-ute a hook 10, and spanners 11, 11, at the other end, is secured to the shank intermediate the handle and grab, in any convenient manner, a bolt 12, passing freely through. the shank and spanner-s, being here shown. This clevis is for use specially as a spliceradjuster, and may be removed when the wrench is used as a hanger and spanwire implement. In proximity to the clevis, on the outer edge of the shank and placed so as to be in substantial alinement with vthe upper surface of the grab when folded down thereon, there is a groove 13, the purpose of which will now be made apparent.

When used as a splice-adjuster, the wires to be spliced, 14, 14, are drawn together in the usual manner as by a block and tackle (not shown) attached to a clip or so-called come-on 15, andbest seen in Fig. 3 of the drawings. The end of one of the wires is inserted into a splice-sleeve 16, and bent back upon itself into a groove 17 provided in the sleeve. The end of the other wire is now inserted into the other end of the sleeve, the Wrench is fitted to the sleeve by setting Patented July 16, 1912.

the end of the sleeve into the groove 6 of the grab, the hook 10 of the clevis is inserted into the link on the clip or come-on and by moving the handle in one direction or the other, the relative position of the wire and sleeve is adjusted at the will of the operator. This may be done with one hand, leaving the other free to bend back the second wire, and finish out the splice.

It. will be seen from the above that one man may, by the use of this implement, effect a splice, and by the use of one hand adjust the wires in the splice-sleeve in any position desired.

When it is desired to use the wrench on a hanger, the clevis may be removed for the sake of convenience in handling, and the operation is as follows: I have shown conventionally in Figs. l and 5, a common form of hanger 18, having

arms

19, 19, from which depend

lugs

20, 20, for the reception of a span-wire 21, used to support a trolley- ,wire 22, shown attached to the lower part ofthe hanger. The span wire is attached to poles on opposite sides of the track, and when it is desired to secure a hanger thereto, one of the lugs 20 ,on the hanger-arm is slipped over the wire, which leaves the wire'resting against the bell-shaped portion of the hanger, and about four inches, depending on the size and shape of the hanger, away from the other arm. To get the span-wire under the lug on the opposite arm has always been diflicult, and was usually accomplished by the aid of a block and tackle, one man pulling on the rope, while another drove the wire into place under the lug when it had been brought into place. With my wrench, the span-wire is inserted into one of the lugs in the usual manner by hand. The curved portion of the grab is placed around the opposite hanger-arm, as shown in Fig. 4;, the span-wire is inserted into the groove 13, on the shank, and by bearing down on the handle into the position shown in dotted lines, the spanwire slips into seat back of the second lug on the opposite side of the hanger-arm.

In case it is desired to release a hanger from a span-wire, the operation is somewhat difi erent, and is accomplished by placing the span-wire in one of the grooves or notches 8 on the outer edge of the grab, moving the grab into position on the hangerarm so that the outer edge of the arm is seated in one of the smaller depressions 7 on the same side of the grab as the notch or groove 8, the wrench being in the position shown in full lines in Fig. 5. By moving the handle of the wrench intothe position shown in dotted lines, and slightly to one side, the span-wire is slipped out from under the lug 20, and freed.

My invention in its broader aspect is not limited to the precise construction herein lVhat I claim and desire to secure by Letters Patent is 1. A hanger-wrench and splice-adjuster comprising in combination, a shank having at one end ahandle; a grab-member piv otally secured to its opposite end, said grabmember being upturned and provided with notches for the reception of the material to be acted on, and a clevis on the shank intermediate the handle and grab-member.
