Integrally formed on the side bars 16 of 95 Figure 5 is a detail view of the movable the body member near the rear ends of said jaw of the clamp. bars are companion inwardly directed Referring now more particularly to the ianges 22, and slidably supported by said drawings, I have shown the present anchor flanges is a channel-shaped movable jaw 23 in connection with a trolley Wire 10, signal straddling the fixed jaw 21 to coact there- 100 wire 11, and feeder cable 12. I have also With. The jaw 23 is substantially U-shaped illustrated a hanger 13 as disclosed in my in vcross section and integrally formed on the (3o-pending application filed January 13, side portions of said jaw are side flanges 1925, Serial No. 2226, as well as a second 211 slidably coacting with the fianges 22.

hanger 14 as disclosed in my co-pendingl aplFormed at the bottom of themovable jaw 105 plication led January 13, 1925, Serial No. are spaced transverse gripping ribs 25 and, 2227.' It is, therefore, unnecessary, in the as shown in Figure 5, said jaw is gradually present instance, to describe said hangers in tapered in depth to conform to the inclinadetail. However, it may be'observed that tion of the-fixed jaw so that the bottom of the hanger 13 is constructed to insulatingly the movable jaw is always disposed parallel 110 to the fixed jaw. However, as the movable jaw is advanced or shifted forwardly upon the body member, lthe bottom of the movable jaw will, due to the inclination of the fixed jaw with respect to the flanges 22, be caused to gradually approach the fixedv jaw. movable jaw is detachable and may be removed at the rear end of the body member.

In conjunction with the clamp, I employ a pair of 'turnbuclles 26 which are'provi'ded at their forward ends with hooks 27 to engage the eyes of the body member of' the clamp while at their rear ends, said turnbuclrles are provided with eyes 28 to engage anchoring studs 29. To install -the device, the studs 29 are arranged to project from the wall or roof. of the mine at opposite sides of the plane of the trolley wire 10, when the eyes Q8 of the turnbuclles are engaged with said studs. The eyes 2O of the body member of the clamp are then engaged with the hooks 27 of said turnbuclzles, when the fixed jaw Q1 of said member is positioned against the 'cable 12 at its upper side. The movable jaw 23 isthen arranged to embrace the cable and is engaged with the flanges 22 of the body member, when said jaw is manually advanced to grip the cable between the jaws. Accordingly, by then adjusting the turnbuckles 26, the cable may be drawn taut and, as will be seen, pull upon the cable will cause the movable jaw to be further advanced upon thebody member by the pull of the cable so that the cable will be rigidly gripped between the jaws of the clamp. Thus, the cable may be stressed, as may be desired, without danger of the slipping` of the clamp while the cable will be securely anchored to extend above the trolley wire, and, as will now be appreciated, the anchor is equally applicable for use vin a system employing veither' the clamps 13 or the clamps 14, or both.

Having thus described the invention, what I claim is: j

1. In a wire anchor, a clamp including a body member having a fixed jaw, and a sub* .stantially U-shaped movable jaw having side first mentioned flanges,

portions to straddle a wire confined between said side portions to lie between the'jaws, the movable jaw being shiftable upon the body member in a plane at an angle to the plane of' the fixed jaw for gripping a wire between the jaws.

2. In a wire anchor, a clamp including a body member having a fixed jaw, flanges on said member at opposite sides of said jaw and lying in a plane at an angle to the plane of' the iaw, and a channel-shaped movable jaw shiftable upon the body member for gripping a wire between the jaws, said movable jaw being provided with side portions having flanges to coact with said first mentioned flanges and having the side portions thereof disposed to straddle the wire for confining the wireto lie between the jaws.

3. In a wire anchor, a clamp including a body member having side and end bars andv provided with a fixed jaw extending between said end bars, lianges on the side bars, and a channel-shaped movable jaw shiftable upon the body member in a plane at an angle to the plane of' the fixed jaw for clamping a wire between the jaws, the movable jaw having side portions provided with flanges to coact with said first mentioned flanges and having the side portions thereof disposed to straddle the wire for confining the wire to lie between the jaws. l

. 4. In a wire anchor, Aa body member having side and end bars and provided at the rear ends of said side bars with eyes to accommodate anchoring elements, an inclined fixed jaw extending between said end bars, flanges on the side bars lying in a plane. at an angle to the plane of the fixed jaw, and a channel-shaped movable jaw to embrace a wire and having flanges to coactwith said the movable jaw being gradually increased in depth to substantially conform to the inclination of the fixed jaw and being shiftable upon the body member for clamping the wire between said jaws` In testimony whereof I afiix my signature.
