mitting power, and the like; and the object is to provide a portable ladder-like insulated support for the two wires, all as will be hereinafter described.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which illus trate an embodiment of the invention, Figures 1 and 2 are respectively a side and front elevation of the support on a relatively small scale. Figs. 3 and 4 are similar views, respectively, to Figs. 1 and 2 of the upper part only of the support on a much larger scale than'that of Figs. 1 and 2. In Fig. 4 the parts are in section at the left-hand side. Fi 5 is a sectional plan on the broken line M N Fig. 6 is a cross-section of the locking device of the winch-frame at line P Q in Fig. 3. Figs. 7 and 8 are detail views of the lever m and its awl, theformer being a face view and the atter an edge view.

The su port consists in a general way of two wood en ladders hinged together at their tops to form when in use an A-shaped frame, Fig. 1, these ladders being held in their divergent ositions by tie-bars below carrying a drum or wire and above by winch-frames carrying winches for straining the steel sustaining-cables. There is a hood at the top for protecting the parts and for housing incandescent lamps. The wooden ladders a and b are or may be alike, and being of wood they serve to insulate the line-wires from the earth. Mounted slidably in metal end pieces on each ladder is a foot or base bar 0, which rests on the ground. In Fig. 2 the dotted lines indicate how this bar may be moved. more or less to one side or the other as occa sion may require to get the best support; The ladders a and b are provided at their respective upper ends with metal hingingpieces d and 6, connected by hinging journals or pins with heads 1 embraced between wooden locks g, secured by bolts and nuts 2, as clearly shown in Fig. 4. The blocks 9 form an insulating-frame between the metal parts cl 6 at each side. The pins f serve also as journals, respectively, for sheaves h, over which pass flexible steel cables (1' and a which extend down, respectively, to winches k, which will now be described. The winch comprises a drum secured by a screw (1, Fig.

5, on a tubular shaft a, rotatively mounted in a swinging framel, which has hinging-eyes that turn on the cylindrical socket portion of the metal hinge pieces (1, being held against sliding up and down thereon by an upper collar b, secured by a pin b and a lower clamping-collar b At its free end the frame Zhas a hook 7", which takes about the cylindrical socket portion of the hinge-piece e between collars b and 12 like those before described.

When the hook r is engaged, as in Figs. 3 and 5, it is held against disengagement by a looking device which turns on the hinge-piece 6 between the collars b and 6 This device comprises two rings 1) and a tic-bar g, which when moved around to the position seen in full lines in Fig. 5 looks the hook in position; but when moved to the position seen in dotted lines at g releases the hook and allows the winch-frame to be swung around, so that the ladders a b may be folded in together. To operate the winch, there is a ratchetwheel a fixed on the end of the tubular shaft a and on the frame Z is mounted a stop-pawl gaged. This lever is for the purpose of rotating the winch so as to put a strain on the cable. 2-) the ladders are connected by a tie bar or frame 8, hinged to the ladder b and hooking at its free end on a rung of the ladder a. This At their lower part (see Figs. 1 and 1 frame has mounted in it a drum or reel tfor wire.

The conductor a Figs. 1 and 3, is provided at its end with a chape c, which engages a the stem'is a ring or eye w, to which may be secured a guy for bracing the support.

It will be noted that each ladder or ladderlike member of the support comprises two uprights and connectin -rungs, and that while the ladder as a whole has means for insulating from the ground the parts it carries at its top means are also provided for insulating the parts carried at one side of the support from those carried at the other sidethat is to say, the sheave h and Winch 7c at one side are insulated from those at the other side.

As only one support is shown, it may be well to explain that the cable or steel-wire rope used for straining the wire is connected at one end to the wire and that the other end of the wire is connectedthrough the shape 0 to the hook t. The Wires at the opposite sides of the su port are connected electrically by the con uctor it.

Having thus described my invention, I claim- 1. A portable support for electric conductors, consisting of two ladders hinged to gether at their upper ends, said ladders being rovided with. means for insulating them om the ground and means for insulating the uprights at one side from those at the other side, and Winches for straining the Wires mounted on the respective sides of the support.

2. A portable support for electric Wires, having two upright members hinged together at their upper ends, a sheave, a winch-frame hinged about one of the members and provided with a hook to engage the other member, a locking device for said hook hinged on the last-named member, a Winch-drum mounted in said frame, and means for rotating said drum.

In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses.
