BINDING DEVICE FOR CIRCUIT GQNDUGTORS.

THOMAS E. MURRAY, OF NEW YORK, N. Y.

BINDING DEVICE FOR CIRCUIT-CONDUCTOR.

To all whom it may concern:

Be it known that I, THOMAS E. MURRAY, a citizen of the United States, residing at New York, in the county of New York and .State of New York, have invented a certain form. Fig. 5 is a sectional view. of the form shown in Fig. 4. Fig. 6 shows in perspective a double binding device of the form shown in Fig. 3, and Fig. 7 is'a side elevation of said device.

Similar numbers of reference indicate like parts.

1 is a late of metal bent at 2 to form a loop, and at 3 to form a flange extending over said loop. A circuit conductor 4 being seated in the loop 2, a block 5 havin a concave recess on its under side is app ied to said conductor, and a screw 6 inserted through a suitably threaded opening in flange 3, clamps the block 5 and said conductor firmly to said plate. The plate 1 may form a circuit terminal which, by means of the binding device, is connected to the conductor 4. Instead of making a loop at the junction of the bent over end of plate 1 and the body portion of said plate, I may turn said end at right angles and then form the loop 2 by curving the extremity of said bent over end, as shown in Fig. 2. In such case the conductor 4 is seated, as before, in the loop, the block 5 ap lied, and the screw 6 inserted through the ody of the plate to bear on said block. In order more completely to inclose the device, I may add a metal cover 7 which at its upper end is bent to form a flange 8, and at its lower end to form a loop 9. This cover is applied as shown in Fig. 2, so that the loop 2 is received in the loop 9, and the flange 8 which has an opening to receive screw. 6 comes above block 5, so that the same screw serves to secure said cover In place.

In the form shown in Fig. 3, the construc- Speoificatlon of Letters Patent. Application filed March 10, 1910. Serial No. 548,360.

tion is the same as in Fig. 2, with the addi-. spacing bar 10 interposed between block 5 and flange 8 of cover 7, and of a clamping nut 11 on screw 6. The screw 6 then passes through the body of plate 1, flan e 8, and bar 10 and bears asbefore on bloc r 5, and is clamped by nut 11.

In Figs. 1, 2 and 3 the conductors couneeted by the binding device are disposed at right angles. In Fig. 4 the conductor 12 is parallel to conductor 4, and is laced immediately upon the block 5 to w ich it is secured by the screw 6. The flange 3 and loop 2 instead of being made part of a plate 1, which is itself a circuit terminal, are formed from a separate plate 13. The clamping nut 11 is here placed on the screw 6 between conductor 12 and flange 8 and bears on said flan e.

In Figs. 6 and the plate 13 has an end portion 14 bent to form the loop 2 for conductor 4, and a side portion 15 bent to form a similar loop for conductor 16. Blocks 5 and spacing bars 10 are inserted as in Fig. 3,

and two screws 6 provided with clamping nuts 11 are employed. By this means I connect two

conductors

4 and 16 at right angles to one another, but without direct clamping of one conductor upon the other.

I claim:

1. A binding device for electric conductors comprising two plates having hook-shaped edges, seated one within the other, and having inwardly turned mutually overla ping flanges opposite to said hooks, and a c am ing screw passing through both of said flanges to engage a conductor seated in the inner hook.

2. A binding device for electrical conductors comprising a plate bent to form a 100 a block in said loop, a spacing bar on sait block, and a screw passing throu h said plate and said bar and bearing on sai block.

3. A binding device for electrical conductors comprising a plate bent to form a loop, a block in said loop, a cover plate receiving said loop and having a flange extending over said 100 a screw passing through said plate an said flange, and a nut on said screw bearing on the under side of said flange.

4. A binding device for electrical conductors comprising a late bent to form a loop, a block in said 00p, a conductor on said block, a cover plate receiving said loop and having a flange extending over said loop, a screw passing through said plate respective loo screws passing through said and said flange and bearing on said conplates and anges and bearing on said ductor, and a nut on said screw bearing on blocks, and clamping nuts on said screws.
