Description

A. M. JOHNSON.

CORD ADJUSTER.

APPLICATION FILED MAR. 5, 1910.

Patented July 22, 1913.

ANDREW M. JOHNSON, OF INDIANAPOLIS, INDIANA.

CORD-ADJUSTER.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed March 5, 1910*. Serial No. 547,411.

To all whom it may concern:

Be it known that I, ANDREW M. JOHNSON, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Cord-Adj usters, of which the following is a specification.

My invention relates to spherical cord adjusters, especially for electric light cord, an object being to provide an efficient and convenient device of cheap and durable construction, a further object being to provide means for holding the cord and for releasing the pressure thereon at will so as to make adjustments easily and without injury to the cord.

There are various cord adjusters in use but those that have come under my observation are either severe on the cord destroying its insulation or do not retain it in adjustment.

In the accompanying drawings and following specification, my invention is more fully described and pointed out particularly in. the claim, and similar numerals indicating similar parts throughout the different figures of the drawings.

Figure 1 shows the adjuster in position on a. portion of the cord 10; Fig. 2 is a sectional view on line 2-2; Fig. 3 is a sec tion on line 3-3; Fig. 4 is a section on line 38; Fig. 5 is a view of spring detached.

The different parts of my invention are represented by different numerals and 1 is the body preferably of wood and spherical in form; 2, 2 are parallel cord o gienings equidistant from center of the ball shaped body; 3 is a spring opening through the center of the body and at right angles to the cord openings 2, 2 and being preferably contracted in bore at f, a to form an annular rib by which is retained the push button 5 provided with a suitable enlargement that said rib will hold it in place. The spring opening is of such proportions that it will cut equally into the openings 2, 2. The inner end of said push button 5 is provided with a conical recess (3, the apex of which points outwardly of the body and is adapted to engage with the inwardly inclined end 7 of each of the springs 8 which are secured at opposite end to body in the present instance by having formed thereon a hookshaped bend 9 and at which point they are driven into said body or fastened in any other suitable manner. The springs 8 lie in their normal position close to the edges of the opening 3, one at each side so that they will cut a considerable depth transversely into the bore of the openings 2, 2 as seen in Fig. 3 and where the movable ends 7 of said springs are seen to project slightly into the recess 6 of said push button so that when said button, is pressed inwardly as shown in Fig. 4t, said springs are pressed toward each other at the points 7 within. said recess 6 by which action the springs are also withdrawn from the bore of openings 2, 2; thus it is evident that when the cord is in place in this device as is shown in Fig. 1 practically filling the openings 2, 2 and the springs 8, 8, are in their norn'ial position as in Fig. 3, that said springs will press against the cord in both said openings 2, whereby it is held in adj ustment and vice versa, when it is desired to adjust it the push button is pressed in firmly with one hand when the adjustment of the cord is readily effected by the other, and when pressure by the operator on the push button is released, the springs force the push button back to normal position and engage the cord again and retain adjustment.

It is evident that any adjuster that upplies any friction whatsoever during ad justment, will in course of time when frequently adjust-ed cause wear on the insulation of the cord and finally expose the conductor, causing short circuiting of electric current or rendering the device dangerous to the operator, and in my device there is no pressure whatsoever possible during adjustment of the cord.

In the application of my device there are a number of deviations that may be resorted to and I desire to have it understood that I hold myself at liberty to make all such alterations or deviations from the exact form and construction her-e shown as fall fairly within the spirit and scope of my invention as clain'led, and

hat I claim as new and desire to secure by Letters Patent is In a cord adjuster a suitable body having a pair of parallel. cord openings through said body and a spring opening through said body cross-cutting the plane of and be tween former said openings and cutting into the bore of each thereof, springs mounted in said spring opening adapted to lie across the bore of said cord openings and adapted to each other upon an inward movement of normally press against a cord extending said button. 10 through latter said openings With suitable In testimony whereof I afix my signature spring pressure, a push button with a re in presence of tWo Witnesses.
