It will be readily understood by those skilled in the art that by the use of my improved support a large number of Wires can be readily placed in position and the drawing of the Wire through each support is entirely avoided.

I claim herein as my invention 1. In a carrier for signal-Wires, the combination of an open-topped frame, one or more rollers mounted in said frame, a second frame adapted to be detachablysecured to the first frame and forming a top therefor, and one or more rollers mounted in the second frame, substantially as set forth.

2. I11 a carrier for signal-Wires, the combination of a frame, one or more posts or plates intermediate of and shorter than the sides, two or more pulleys or rollers loosely mounted between the intermediate posts or plates and the sides, a second frame adapted to fit between the sides of the first frame, two or more rollers mounted in the second frame, and means for removably securing the second frame in position, substantially as set forth.

3. In a carrier for signal-wires, the combination of a U-shaped or open-topped frame, one or more posts or plates intermediate of the sides of the frame, one or more rollers loosely mounted in the slots or pockets formed by the posts or plates and sides of the frame, and a detachable crossbar for holding the wires in the slots or pockets, substantiallyas set forth.

In testimony whereof I have hereunto set my hand.

JAMES CHALMERS, JR.
