TROLLEY-wl RE HANG ER.

SPECIFICATION forming part of Letters Patent No. 588,923, dated August 24, 189?.

Application iiled June 5, ISQG. Serial No. 594,436. (No model.)

To all whom, t may concern.-

VBe it known that I, GEORGE EDWIN J OHN- sON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a certain new and useful Improvementin Trolley- Wire Hangers, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings.

My invention relates to improvements in the method of attaching trolley-wires to trol-l wire as at present constructed is as follows:

First. The connection must be soldered to the trolley-wire, which renders it difcult to put them up.

Second. When it is desired to take either the trolley-wire down or remove the supportingwire for any purpose, it is troublesome, as in so doing it is necessary to melt the solder connection holding the parts together.

The advantages of this devicel over those now in use are- First. In building a new line the supporting-wire can be put up before the trolley-wire i's strung, as the connection can be attached to both the trolley-wire and the trolley-supporting wire without disturbing either of them.A

Second. In making repairs this device is a decided improvement over those now in use, as it can be more easily and quickly applied, and when once in position it can be easily moved in either direction when it is necessary to do so in order to make a trolley-line hang properly.

Third. The device so insulates a trolleywire from the trolley-supporting wire that no current can get into the supporting-wire.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I is a vertical view, partly in section, of my device, showing it as applied to a trolley-wire and a trolley-supporting wire. Fig. II is a vertical view, partly in section, of my invention, taken at right angles with Fig. l. In this View the device is also shown in connection with a trolley-wire and a trolleysupporting wire. Fig. III is an end view of the hard-rubber tube used for insulating the supporting-wire so that no current can get into it. In this View a slot is shown which extends the full length of the tube. The object of this slot is to provide adjustment, so that the tube can be closed tightly upon a supporting-wire. Fig. IV is a prospective view of the insulator.

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents a trolleywire; B, a trolley-wire-supporting wire; C, my connection for uniting the trolley-wire A to the trolley-wire-supporting wire B; D, the screws for drawing the connection tightly upon the trolley-wire-supporting wire; E, the

screws 'for drawing the connection tightly upon the trolley-wire A, andF the hard-rubber tube employed for insulating the trolleywire-supporting wire, so that no current can `*pass into it.

In operation the hard-rubber tube is placed within the connection, as shown in Fig. I, with a slot cut its full length, as shown in Figs. I and III. The object of this slot is to allow the tube to close tightly lupon the trolley-wire-supporting wire. The connection being slipped upon the trolley-wire-supporting wire with the insulator in place it is obvious that no current can pass from the trolley-wire to the trolley-supporting wire.

The parts of the connection into which the trolley-wire is fastened are opened by loosening the screws E to allow the trolley-wire to enter from the bottom, and when the trolleywire is properly introduced between the said parts the screws E are drawn up, securely clamping thetrolley-wire within the part of the frame into which it is introduced. Thus the device is manipulated when applying it.

Now having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. As means for attaching a trolley-wire to a trolleysupporting wire, a connection in IOO which the frame is made of one piece with a suitable insulator for preventing the current from the trolley-wire from passing into the trolley-Wire-supporting Wire, and suitable screws for fastening the connection to both the trolley-Wire and the trolley-Wire-supporting wire, substantially and for the purpose as specified.

2. In a connection for attaching a trolley- Wire to a trolley-supporting Wire, the combination of a frame with suitable screws for fastening the said frame to a trolley-supporthole, so that by closing the said slot, the said 2o hole will be reduced in size, for the purpose of clamping the said frame tightly to the said trolley-Wire-supportin g Wire, or a trolley-Wire substantially as described.

3. In a trolley-Wire support, the combination With a split clamp vfor embracing the trolley-Wire, of a split tube formed integral With said clamp and arranged at right angles thereto, a split-insulator cylinder of hard rubber arranged Within said split tube, and screws tapped through said clamp and split tube for contracting them about the trolley- Wire and supporting-Wire, substantially as described.
