cuP OR SUPPORT FOR TROLLEY-WIRES.

SPECIFICATION forming part Of Letters ?atent No. 663,198, datedDecembe-r 4, 1900.

Application filed March 20, 1900. Serial No. 9,386. tNo model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. RUSSELL, of Watertown, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Clips or Supports for Trolley-Wires, of which the fol- V lowing is a description sufficiently full, clear, and exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the same.

This invention relates to a clip for engaging an overhead-trolley wire and holding it properly suspended and in proper position from the supporting-wires and to prevent the longitudinal movement of the wire through its support. I

It is the object of the invention to provide a clip the two parts of which may be hinged together so as to keep them in place for ready adjustment upon and attachment to the wire.

It is also the object of the invention to provide a clip with structural characteristics, in virtue of which one part may not have a tendency to slide upon the other when the parts are being placed in position.

It is further the object of the in vention to provide improved means whereby the wire secured in the clip may not be moved longitudinally by force or strain put thereon in a longitudinal direction, and whereby the trolley running on the Wire may pass therefrom on a line with the feathered-01f clip, and the trolley thus made to run as smoothly over the clip or from the clip to the wire as though running along on the uninterrupted surface of the wireitself.

It is the further object of the invention to provide other improvements incidental to the foregoing, all of which will hereinafter more fully appear.

Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features,

as the case may be, wherever they occur.

Of the drawings, Figure l is a side view of the clip complete in closed position. Fig. 2 is an inside view of the hinged part. Fig. 3 is an inside view of the main or hinging part. Fig. 4 is a view of a length or it may be two ends of a wire placed in the clip. Fig. 5 is a view in side elevation of a modified form of the invention. Fig. 6 is a cross-sectional view taken on line 6 6 of Fig. 5, and Fig. 7 is a cross-sectional view taken on the line 7 7 of Fig. 5.

In the drawings, A designates the hinging member to which the part of member B is hingedfas at a a. The hinging is accomplished by casting lugs on the two members and passing a pintle or screw through the hole formed in the two lugs, as will be read ily understood. The faces I) and cof the two members are made flat, so that when theyare brought together'they will match or lie flat one upon the other. The hinges a are formed on the upper edges of the members and are so arranged that when the parts are loosened they may be separated from their bottoms upward and let the wire d out of the irregular or undulatory groove e formed in each mem' ber. It will be understood, of course, that the groove will be half-round in each memher. The clip is provided with the usual hub g for. the attachment thereto by suitable equipments of the supporting or cross wires. The groove (2 will run through the members in such manner that it will leave the ends of the clip upon a line coincident with that of the Wire entering the groove-in other words, so that the trolley running along upon the wire will pass onto the groove without interruption or without a broken surface to cause sparking and run the length of the clip, entering again upon the wire in the same manner. To accomplish this, the ends of the clip are feathered down, so that they will be coincident with the surface of the wire.

The groove e may have bridge-pieces it formed across it, which bridge-pieces may fit in grooves t, formed in the wire, so that the two ends of a wire may be spliced or held in the clip between the two members against be ing operated.

Dowel-pinsj will be formed in one clip to fit in holes 7c in the opposite clip, and the dowels may be arranged so as to enable the wire to be caught thereon and the operator to bend it, so that it may be readily forced into the groove. The groove may be undulatory, as shown, or it may be simply a curved groove or a groove, as is indicated in Fig. 5, of any other form that will tend to hold the wire from being pulled out lengthwise between the two members of'the clip.

Holes I will be formed in the bosses of the clip for the reception of screws m, with which to screw the two members together, and holes at may also be formed in the bosses of the clips for the reception of cross-wires or Wires to sustain the clips in position when taking a curve.

By hinging the parts together as described they will always be in position to be readily clamped upon the trolley-wire, and by mak ing the groove curved and otherwise forming forth.

2. A clip for sustaining trolley-Wires consisting of two members hinged together and provided with an irregular groove ,in which the wire may be placed and upon which the members are adapted to be clamped, the lower ends and edges of the clip being feathered 0E coincident with the trolley-wire entering the clip, as set forth.

3. A clip for sustaining trolley-wires conit as described the Wire may be clamped and sisting of two members adapted to be secured held between the two members. Furthermore, the feathering down of the clip'so as'to be coincident with the lower face of the wire enables the trolley to pass over the clip without arcing or sparking. Again, in the construction of the clip as described it is possible to make it of minimum weight and yet of maximum strength so far as its functions go.

I do not limit myself to the exact form of the groove between the two parts, nor do I limit myself to the position of the dowels and holes for their reception, since these and other parts may be varied within the limits of mechanical ability Without departing from the nature or spirit of the invention;

The ends of the trolley-wire may be spliced in the clip by turning them up at an angle and locking them in place between the two parts.

Fig. 5 clearly shows the two members feathered down at the ends to a point coincident with the wires.

Having thus explained the nature of the invention and described a way of constructing.

and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it

7 is declared that what is claimed is 1. A clip for sustaining trolley-wires consisting of two members hinged together and together on the wire, and provided with an undulatory groove having bridge-pieces for engaging-the ends of Wires to'splice them and hold them against being pulled through their grooves. I

4. A clip for sustaining trolley-wires consisting of two members provided with means as setforth for holding them securely together and provided with dowel-pins and holes, as set forth, for also keepingthem in place, substantiall as described.

' 5. A c ip for sustaining trolley-wires consisting of two members provided with means substantially as set forth for holding them securely together'an'd an undulatory groove running down at the ends, and the latter feathered to an edge coincident with the position of the wire, so that the trolley may enter from the wire or the wire to the clip on a smooth line without sparking substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 15th day of October, ,A. D. 1899. 7

ARTHUR W. GRoss'LEY, ANNIE J. DA1LEY.
