TROLLEY-WIRE HANGER AND SPLICE R.

SPECIFICATION forming part of Letters Patent No. 587,740, dated August 10, 1897.

Application filed April 13, 1897.

To all whom it may concern:

Be it known that I, CHARLES K. KING, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Improvement in Trolley Wire Hangers and Splicers, of which the following is a specification.

This invention relates to trolley-wire hangers and splicers.

The object of the invention is to provide a hanger or splicer which will more efficiently support a conductor or more efficiently couple up the ends thereof than any device heretofore employed for such purpose.

The invention consists substantially in the construction, combination, location, and relative arrangement, all as will be more fully hereinafter set forth, as shown in the accompanying drawings and finally specifically pointed out in the appended claims.

Referring to the accompanying drawings and the various views and reference-signs appearing thereon, Figure 1 is a View in side elevation of a form of-hanger embodying my invention applied to a trolley-wire. Fig. 2 is a side elevation showing a slightly-modified form of hanger applied to a trolley-wire and embodying my invention. Fig. 3 is a side elevation of a splicer or ear applied to trolley-wire and embodying my invention. Fig. 4 is a transverse sectional view of a hanger or splicer embodying my invention as applied to what is known in the art as a figure-eight trolley-wire. Fig. 5 is a similar view showing the hanger or splicer embodying my invention as applied to the round wire or conductor. Fig. 6 is a similar view showing the hanger or splicer embodying my invention as applied to What is known in the art as a clover-leaf conductor. Fig. 7 is a similar View showing the hanger or support before the flanges thereof are clamped around the conductor.

The same part is designated by the same reference-sign Wherever it occurs throughout the several views.

In carrying out my invention I provide the hanger or splicer with transverse rivet-holes at such a point in the side flanges thereof Serial No. 632,032. (No model.)

that such holes will intersect a portion of the trolley-wire or conductor when the hanger or splicer is in position thereon, and I then pro vide similar and registering transverse perforations or holes through the conductor or wire, and finally complete the operation by firmly riveting, bolting, or otherwise securing the hanger or splicer to the conductor by any suitable or convenient form of rivets, bolts, or the like, arranged to pass through the conductor and into the flanges of the hanger or splicer. V

In Fig. 1 I have shown my invention as applied to one form of hanger, reference-sign A designating the hanger, B the conductor or trolley-wire, and O the securing devices, passing through the conductor and into the hanger.

In Fig. 2 I have shown a slightly-different type or style of hanger D, but the principle of my invention, as illustrated in this figure of the drawings, remains the same-that is,

the hanger D is riveted or secured to the wire or conductor B by means of the rivets, bolts, or other securing devices 0, passing through the conductor and into the hanger.

In Fig. 3 I have shown my invention as applied to a splicer for joining the abutting ends of two sections of conductors, referencesigns B B representing the ends of the wire or conductor, E- the splicer, and O the rivets, bolts, or the like, passed transversely through the sides of the splicer and also through the conductor.

It is evident to persons skilled in the art that my invention may be applied with equal facility and efficiency to conductors or trolley-wires of any desirable shape in cross-section. have shown my invention as applied to figure-eight conductors. In this case the secur- For instance, in Figs. 1, 2, 3, and L I ing devices 0 pass through the conductor adjacent to the thin web or neck connecting the two round portions of the conductor,as clearly IOO applied to a round conductor B the securing rivets, bolts, or thelike O passing transversely through the flanges of the hanger or splicer F and also through the upper half of the conductor.

In Fig. 6 I have shown my invention as applied to a conductor B which has a triangular shape in cross-section and which is known in the art as a clover-leaf conductor. In this case, the rivet-s, bolts, or other form of securing devices 0 pass transversely through such conductor at'a point adjacent to the thin neck at the juncture of one of the round portions of the conductor, as shown, and efflciently secures thereto the side flanges oft-he hanger or splicer F.

In Fig. 7 I have shown a transverse section of a preferred form of hanger before being placed upon the conductor. It will be observed that in this form the side flanges G G are flared, whereby the groove H, which receives the conductor ortrolley, is sufficiently large for the hanger to be seated directly on the conductor. The said flanges G G are then bent or clamped around the conductor or trolley-wire and the securing devices passed therethrough and through the conductor to complete the joint. Of course it will be understood that the holes J through the flanges G may be formed during the course of manufacture of the hanger or splicer. This is especially true of hangers or splicers made of soft metal. If desired, however, these holes may be bored in the flanges G G after the hanger or splicer is placed on the trolley-wire or conductor and said flanges are clamped down upon the conductor. In this case of course the holes are made at the same time all the way through the conductor.

The securing devices 0, which are arranged to pass transversely through the conductor and into the flanges of the hanger or splicer, may be. ordinary rivets, as shown in Fig. 4, or, if desired, they may comprise bolts O, headed at one end' and threaded at the other end to receive a nut L, or the nut L may be omitted and the threaded end of the bolt screwed directly into opening J of the hanger or splicer.

In the case of splicers it is not necessary that the flanges G be flared and then subsequently clamped down upon the conductor. The reason is apparent. The splicer is used to connect the abutting or adjacent ends of two conductor-sections. The slot or groove H,therefore,in the case of splicers maybe cast or formed of the desired configuration to receive the conductor, as shown, for instance,

in the cross-sectional view in Fig. 4, and then advantageous in the case of figure-eight and clover-leaf conductors, and in such case the cross-sectional area of the longitudinal groove or seat II should be such as to receive snugly and neatly the rib of the conductor endwise therein.

From the foregoing description it will be seen that I rigidly secure the hanger 0r splicer .to the conductor, insure a good electrical contact and joint in the case of the splicers, and an efficient support for the conductor in the case of hangers, and in both cases avoid impairment by reason of the swaying motion of the conductor due to the wind or the passage of the trolley. It will also be seen that I do not depend merely upon clamping the flanges of the hanger or splicer around or partially around the conductor, and I also avoid the use of solder. In both such cases the swaying of the conductor by the wind and also by the passage ofthe trolley therealong rapidly impairs the support and also the electrical contact.

Having now set forth the object and nature of my invention and forms of devices embodying the same, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent of the United States, 1s-
