To all whom it may concern: 1

Be it known that 1, Aueusr JiiRcnNs, a subject of the German Emperor, residing at 133 Springweg, Utrecht, Holland, have 1nvented certain new and useful Improvements in Means for Fastening the Dangling End of a Broken Overhead Electric Conductor; and I do hereby declare the following to be a full, clear, andexact description of the invention.

The invention relates to overhead electric conductorsior trolley systems and the like, and its object is to provide a new and improved means for drawing up and fastening the dangling end of a broken overhead electric conductor, to prevent short circuiting of the electric circuit and to reduce the danger of electric shocks and electrocution to human beings and animals liable to come in con tact with the broken end of the electric con-' ductor. a

In order to accomplish the desired result, use is made of a pulley block adapted to be fastened to an overhead support adjacent the break of the electric conductor, a gripping device for clamping the dangling end of the electric conductor, and a rope connected with the gripping device and passing over the pulley of the said pulley block to permit of drawing the gripping device and with it the broken end into an elevated position.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. I

Figure 1 is a perspective view of the pulley block and means for drawing the same into position on the supporting cross wire of a trolley wire or a similar electric conductor; Fig. 2 is a perspective view of the device with parts in position for raising the pulley block clamp and dangling end of the electric conductor; Fig. 3 is an enlarged side elevation of the pulley block; and Fig. 1 is a perspective view of the clamping device.

As shown in Figs. 1 and 2, the device is used for raising the dangling end of a broken overhead electric conductor 1 to the supporting cross rod or wire 2 near the broken end of the said conductor 1. For the purpose mentioned use is made of a pulley block 3 provided at its casing 4 with a rope 5 adapted to be thrown over the supporting wire 2 to allow of drawing the pulley block 3 up to the said supporting wire and to fasten it thereto. For this purpose the casing 4 of the pulley block 3 is provided with a conical head 6 and with hooks 7 immediately below the conical head 6 so that when the pulley block 3 is drawn up by the use of the rope 5 then the head 6 finally passes up over the supporting wire 2, and one of the hooks 7 hooks onto the said supporting wire to hold the pulley block in raised posi tion and supported on the supporting wire 2. A rope 8 passes over the pulley 3 of the pulley block 3 and terminates at one end in branches 8 attached to the insulated handles of a gripping device 9, preferably in the form of a pair of tongs, having jaws 10 between which is clamped the broken end of the electric conductor 1, as shown in Fig. 2-. A spring 11 is interposed between the handles of the clamping device 9 so as to hold the jaws 10 in firm contact with the broken end of the electric conductor 1. It

will be noticed that after the pulley block 3 has been raised and attached to the supporting wire 2 then the gripping device 9 is attached to the broken end of the electric conductor, and then the operator pulls on the free end of the rope 8 to raise the gripping device 9 and with it the dangling end of the conductor 1. In order to prevent the rope 8 from return movement use is made of a serrated spring-pressed shoe 12 mounted in the casing 4: of the pulley block 3 and engaging the rope 3 so as to lock the clamping device 9 and the dangling end of the electric conductor 1 in raised position.

. It will be noticed that by the arrangement described the dangling. end of the broken electric conductor is raised into safety position to'allow trolley cars to pass along the line without interference from the broken end of the electric conductor, it being understood, however, that a trolley car must pass the broken portion of the track under its own momentum. It will further be noticed that by raising the broken end short circuiting of the electric circuit is prevented and danger to passersby is removed. Although particular means have been shown, that is, the rope 5 for raising the pulley block 3 into position on the supporting wire 2, it is evident that the said pulley block may be hung onto the supporting wire 2 or other support by the operator climbing up a ladder or the like.

I claim 1. Means for drawing up and fastening the dangling end of a broken electric conductor, comprising a clamping device adapted to engage the torn dangling end of the electric conductor, a pulley block, a rope connected with the said clamping device and passing over the pulley of the said pulley block, and means for attaching the said pulley block to an overhead support.

2.
