ADJUSTER FOR ELECTRIC-LIGl-ET GORDS OR CABLES.

Application filed November 12, 1907.

movable from a cord already in position without disturbing or removing the cord liXt-ures or iastenings. etliciently operative in any position of the adjuster, and which will attord at all times opportunity to inspect the cord or cable without removal of the adjuster. These objects l attain by the novel construction. combination and arrangement oi parts hereinafter described, and shown in the accoiupanyiug drawings. in whicln- Figure 1 is a front elevation of my adjuster. Fig. is a side elevation of the same. Fig. 3 is tront elevation showing the adjuster operatively applied to an electric light cord or cable.

Similar reference letters indicate like parts throughout the drawings.

A represents the body of my adjuster which is provided with a centrally located channel way A extending entirely across said body and open on its front and at each end. and having its side walls disposed in converging planes. and each side wall provided witl a concave channel or groove, (1, in diately disposed in said wall and extending longitudinally thereof. The ends of said side walls are rounded and said groove carried through such rounded end in order to prevent injury to the cord or its insulation. B represents a wedge-shaped binding-member arranged and adapted to be seated and operatively slidable in said channel-way A The side walls of said member B are disposed in converging planes and are each pr vided with a mediately located longitudinally directed groove, as 2), arranged and adapted. when said member is opcratively seated in said channel-way, A to register with the groove in the contiguous side all of said channel way, and in conjunction therewith constitute a duct or passageway for the electric light cord or cable passed therethrough. Said member B is Specification of Letters EPatent.

provided with a mediately located oblong aperture. o", and a screw 5, or other :tastening means, passed through said aperture and into the body A thereunder, serves to hold said member ii in operative position in said channel A and also to limit its reciprocating movements in either direction. Said binding-member l) is slid backward in said channel A to afford opportunity to easily insert the cord by passing the end through one duct and back through the other in such manner that the bight of the cord will lie around the wider end of the member B, changing with easy bends from a perpendicular to a horizontal position and back to its final perpendicular position to connect with the lamp socket. (Fig.

in cases where it is desirable to apply the adjuster to a cord already installed and it is not desirable to remove or disturb the connections. the biriding-member ii is bodily removedfrom the channel A. on witlnlrawiug the screw s. or other fastening means. the cord placed in the channel A with its bight or loop extending beyond the wider opening of said channel, the member B inserted between the parallel runs of the cord and reglaced in the channel A and the screw 5 replaced. The cord will then be held in the juxtaposed grooves of the meiuber B and channel A as shown in Fig. 3, and strain on the cord will torce the member B tightly between the side walls of said channel. and the adjuster thus secured on the cord.

To shift the position of the adjuster on the cord to shorten or lengthen the latter, or for purposes of inspection of the cord, ten sion applied on the cord in the direction of the bight or loop will cause the member 1 to slide backward out of the channel A until stopped by the screw 8. The cord will thus be released and mzj be readily inspected or the adjuster may be moved to another position on the cord. as the case may be, and the member B then forced into its clamping position. (Fig. 3.) The weight of the lamp and socket will be sutlicicnt to hold the binding member clamped in the channel A I claim as my invention and desire to secure by Letters Patent:

fin adjuster for electric light cord or cable consisting oi a body men'iber provided with a centrally located channel way extending entirely across said body and open on its front throughout its length, and hav ing its side Walls disposed in converging planes, and each said side Wall provided with a mediately disposed groove extending longitudinally thereof, a Wedge-shaped binding member adapted to be removably seated in said channelway for limited reciprocating movement therein, and provided With a mediately located longitudinally directed oblong aperture, and with a longitudinally directed groove mediately located in each side Wall and arranged and adapted to register with the groove in the contiguone wall of said chairoeiway when said and adapted to hold said binding-1nember 20 in said channelivav and permit limited reciprocating movement of said bindingmember therein.
