FRANK J. GAMMACI-IE, OF LANCASTER, PENNSYLVANIA.
Application filed October 24, 1913.
To all whom it may concern Be it known that I, FRANK J. GAMMAOHE, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Cord- Adjusters, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to a cord-adjuster of that class which is used for adjusting the length of electric light drop cords. The present devices employed for this purpose consist in either a ball or a block having two holes at right angles to the line of cord, through which the cord is passed, but they are unsatisfactory in that they are hard of adjustment, and after repeated use they strip the insulation from the cord.
The object of the present invention is to provide a device that shall be cheap, durable and efficient, allowing of a straight pull of the cord therethrough.
Another object of the invention is to provide a device \that shall hold the cord by friction, be easily adjusted and require less cord by its use.
till another object is to provide a device that may be instantly placed on a cord without detaching either end of the cord, and may be removed in like manner.
W'ith these and other objects in view, my invention consists in certain construction and combination of parts as will hereinafter be fully described and claimed in the annexed specification and illustrated in the accompanying drawings which form a part of this application, an in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my invention as shown, that I do not confine myself to the exact design, as slight changes may be made in the construction and arrangement of the several parts with out departing from the spirit of the invention.
Specification of Letters Patent.
Patented Feb. 16, 1915.
Serial No. 796,986.
In the drawings: Figure 1, is a perspective view of the device as applied to a cord, the cord being in position for sliding the adjuster thereon. Fig. 2, is a side elevation of the same, showing the cord in an adjustable position.
Referring to the drawings, the device comprises a body portion 10, of insulating material, such as wood, rubber, fiber, or porcelain, which is formed with the angular ends or hearing lugs 11, which are provided with the longitudinal alined holes 12, which are cut away on their opposite sides as at 13, to admit the cord 14. For returning the cord 14, a frictional double arm gripping spring 16, is provided which is mounted upon the body portion 10, by the screws 15, with its ends bearing upward in the orifices 13. The ends of the spring 16, are provided with insulating frictional gripping blocks 17 which are concave upon their upper surfaces and bear upon the cord 14, holding it against the lug 11. It will thus be seen that the cord may be drawn straight, and the device slid upon it without fear of stripping or hurting thecord; and for adjustment the cord may be pulled out or looped, as shown in Fig. 2. For attaching or detaching, the cord may be readily snapped in or out through the orifice 13, against the tension of the spring 16.
Having thus described my invention what I claim as new, and desire to secure by Letters Patent is p In a cord-adjuster of the class described, a slide having alined orifices in the ends thereof, said orifices open upon the opposite sides and a spring mounted in said slide with its ends extending into said orifices and coacting with the wall thereof to retain a cord.
In testimony whereof I affix my signature in presence of two witnesses.
