and useful improvements in Anchors for Overhead Wires, of which the following is a specification.

The object of my invention is to provide an improved means for suspending the overhead Twires for electric cars.

'in the drawings forming part of this speciiication, Figure l is a perspective view ci my improved anchor.l Fig. 2 is a section taken taten on 'the line 3 3 of l.

l tail, partlyin section, showing the attachment the line 2 2 of Fig. l. Fig. 3 is a section Fig. 4t is a dethe angle stay-Wire. Fig. 5 is a view in perspective showing my device adapted for support for double wires. Fig.. 6 is a perspective view showing the anchor i'or double trclleywwires. Fig. 'Z is a vietv, partly in section, showing a method oi` insulation for the connection for the stay-Wire.

The double pullover is made in the shape of an arm, the ends curved downward and bi-V furcated, as at B, for the attachment of the straight stay-Wire connection il Gn this pullover is a boss D, through which is drilled a hole for passage of the bolt The lineear E' has the usual clamping or securing device d for attaching the line-Wire h and has, in addition, at each end the perforated ears F and at its center the boss G,Which is tapped to receive the screw-threaded end of the bolt E, which connects the pullover with the lineear. g

ll is a side .piece which is made with setolics at the end, as shown, these set-od portions having holes for attachment of the connecting-pieces for angle stay-Wires. Near each end of this side piece is a boss or projection l, tapped to receive the threaded end of the bolt J, by which nfleansl the line-ear and side piece are connected. lThe manner of this connection is'clearly shown at the left in Fig. 3. The connection C, by which the straight stay- Wires are connected to the pullover, isin one piece, cast or formed in any suitable Way, having the general shape of tivo rings joined vWashers M M.

byabolt K. This connection is clearly shown in Fig. 2. The insulation is secured by the insulating-bushings L, L', and L2 and the lt desired, Washers of insun lating material may also be used under the head of the bolt and under the nut, as shown in. Fig. 7. This makes a very light, compact, and strong connection and one that is easy to connect, disconnect, or repair. v

The connection for the angle stay-wires consistsof the piece N, having a hole 0 drilled atone end and the other end bifurcated, as

lat P. The bifurcated end is fitted. over the end of ythe side piece and secured by a holt Q, as clearly shown in Fig-s. 3 and fi. The method of insulation is the same as in the connectionfor the straight stay-connecting piece y connection is such that the pullover Will move Without undue strain, so that the straight stay-wires will always be in the same line. When thestay-wires, especially the angle ones, are attached directly to the line-ear, as

yis noW the custom, they make a il-shaped recess or pocket. ln case the trolleywheel should jump from the Wire it will be caught in said recessor pocket and the harp be pulled out or the Wire and connection broken.l With my construction this could not happen. The trolley would pass under the anchor Without danger of catching, and consequently with no danger of injury either to the trolley or the overhead Wires.

ear could be made in one piece or the Whole device could be cast in one. ln such case of course the self-adjusting feature would be lacking.

In Fig. 5 I have shown my invention adapt- 1. In a securing device for overhead elec tric wires, the combination of the double pullover, the line-ear connected thereto, the side piece connected to said line-ear and means on said pullover and side piece for attaching the stay-wires, substantially as described.
