THE LOVE ELECTRIC TRACTION COMPANY, OF SAME CONDUCTOR-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 532,164, dated January 8, 1895. j

Application filed May 9, 1894. Serial No. 510,652. (No model.)

To @ZZ whom ,it may concern,.-

Be it known that I, JOHN C. LOvEof Chicago, in the county of Cook and State of Illi-l nois, have invented certain new and useful Improvements in Conductor-Supports; and I do hereby declare that the following is a full,

clear, and exact description thereof, reference .f

being had to the accompanying drawings, and

to the letters of reference marked thereonp which form a part of this specitication.

This invention relates to im provements in devices for supporting the line wires or con-A ductors of electric railroads. Its object is to provide an improved construction in devices of the character referred to; and it consists in the matters hereinafter set forth and par-Y` ticularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side elevation of a line wire support ernbodying my invention in one form. Fig. 2 is a transverse section on line 2--2 of Fig. l. Fig. 3 is a top plan section taken on line 3 3 of Fig. l. Fig. 4 is a similar view of a construction slightly modied from that previ-Y ously shown.

In said drawings, A designates the line wire or conductor and B stationary supporting rods or bars from which the line wire is suspended.

C is a clamp comprising two. separable plates C and C2 which are shaped at their lower ends to form jaws c between which the line wire A is gripped and held.

As herein shown, the wire A is provided on each side above its center with a longitudinal groove c, and the lower edges of the jaws c are turned inward to engage said grooves, so that the wire is held solely by its upper portionK wire or conductor A firmly held between the jaws c at their lower ends.

The wedge C3 is conveniently locked in place after being driven in as far as desired by means of a malleable strip, strand or wire C4 which is inserted and held between the outerface of the wedge andthe loop, and has its ends c4 c5 ben-t so as to engage the end ot (the wedge and the side of the loop in such manner as to prevent the wedge from slipping 6o from its place.

, A longitudinal groove c3 is made in the outer face ot' the wedge C3 to form a seat for the wire C4, the ends c4 c5 of which are bent over in opposite directions to engage respecti ively the head of 'the wedge and the side of the loop c remote from the head of the wedge. The end c5 of the locking wire will ordinarily be bent over before the wire is inserted, its other end being left straight. The straight end of the wire is placed in the groove c3 at the small end of the wedge and slipped along said groove beneath the loop c until its bent end c5 comes in contact with the edge of said loop. The end c4 of the wire is then hammered or otherwise bent over to closely engage the head of the wedge, and obviously thereafter prevents the wedge from working loose. Av recess c6 in the head-'of the wedge forming a continuation of the groove c3 affords a seat for the end c5 of the wire when bent `over as described.

The clamp C is, as herein shown, suspended and insulated from the stationary' support B by means of a block D of insulating material in which the upper end of the plate C, which is extended above the plate C', is embedded said block being grooved at its opposite sides vto engage the supporting rods B B, flanges c7 c7 projecting laterally on both sides of the 9o plate C' along the upper edge thereof to afford a stronger connection between the' plate and the block. l f

Instead of the rods B B any form of stationary support may be used, which may form part of an overhead or underground railway structure and may be engaged with the insulating block D in any desired manner. In the particular form herein shown, the two parallel rods B B are similar to those which roo are secured in the yokes of a slotted underground conduit, of a kind shown in prior patents granted to me, and the block D is provided on opposite sides with grooves d adapted to engage the said rods when the block is placed between the latter. This construction obviously permits the line wire supporting device to slide freely endwise on the support B and provides for anylongitudinal movement of the line Wire resulting from any cause, as from the application thereto of tension devices of the nature set forth in my previous Patent No. 511,345, dated December 26, 1893.

1n Fig. 4 l have shown a slightly modified construction of .the insulating support in which the wedge C3 is reversed or turned with its grooved face inward against the plate C2. The end c5 of the locking wire C4 in this case engages the edge of the plate C2 instead of the edge of the loop c', asin the construction rst described, but obviously the locking effect is the same in either case, though the construction shown'in Fig. 1, 2`and 3 is the most convenient and is preferred.

1 claim as my invention* 1. A supporting device for electric conductors provided with a clamp comprising two separable plates between the margins of which the conductoris gripped and held, one of which is apertured and the other provided with a loop which projects therefrom through said apertured plate, and a wedge or tapered key driven through said loop and engaging the outer face of the apertured plate to force the plates toward each other, substantially as described.

2. A supporting device for electric con dnctors comprising two separable plates be-` tween the margins of which the conductor is held, one of which plates is apertured, and the other provided with a loop which projects therefrom through the apertured plate, a wedge passing through said loop and engaging the outer face of the apertured plate, and a locking wire inserted between the said wedge and an opposing part of one of the plates, said. wire being bent at its ends to engage the head end of the Wedge and an oppositely facing surface of one of the plates, substantially as described.

3. A supporting device for electric conductors provided with a clamp comprising two separable plates between the margins of which the conductor is gripped and held, one of which is apertured and the other provided With a loop which projects therefrom through said apertured plate, a wedge passing'throngh said loop and engaging the outer face of the apertured plate, and a locking wire seated in a groove in said wedge andbent at its ends to engage the head of the wedge and an oppositely facing surface of one of the plates, substantially as described.

4. A support for electric conductors .comprising an insulating block, two separable plates between themargins of which the conductor is held, one of which plates is extended past the other and embedded in said insulating block, one of said plates being apertured and the other provided with a loop which projects therefrom through the apertured plate, a wedge passing through said loop and engaging the outer face of the apertured plate, and a locking device to hold the wedgein place,substantially as described.

In testimony that I claim the foregoing as my invention Iaftix my signature in presence of two witnesses.

JOHN C. LOVE.
