JAMES E. SIMPSON, OF BROOKLYN, YORK.

NONTWISTING DEVICE FOR, TELEPHONE AND OTHER CORDS.

Application filed October 19, 1922.

To all whom it may concern:

t i. {O'Wll that l, JAB/{ES E. SmirsoN, a the United States, residing at 569 s Avenue, in the borough of 'n, in the county of Kings and State ew York, have invented certain new and improvements in Nontwisting Defor Telephone and Other Cords, of which the "following is a full, clear, and W erect specification.

'lhis *ention relates to means for pretelephone cords from twisting or becoming in red, and my improvement is directed to the prod. :tion oi a simple device, 15 ad: to grip a telephone cord at two d points in its length, to thus on the line thereof between objects, such as the receiver and base, while causing the sire]; to be held, relatively to its extent,

lined loop which is incapable of twisting or becoming kinlre l.

The device is equally applicable to the cert length that extend. between the transt d of a movable or desk telecl the. battery box.

the device, though primarily infor with telephone cords, is applicable with other lengths of f thereof.

such cords are permanently seopposite ends to movable r immovable points or objects, also though the device is primarily intended for use with telephone cords, it is equally applicable for use as a silent salesman or advertising medium.

Briefly expressed my improved non-kink ing device for cords consists of a piece of still material having means at separated points thereoti for tensionally gripping a cord of designated thickness, to thereby establish a fixed loop comprising the slack or normally unusued portion of the cord length.

(Ether features and advantages of my invention will hereinafter appear.

In the drawing Figure 1 is a perspective view of the clevice in one of its forms, as applied to a cord.

Fig. is a plan view of the device in a modified form thereof, with the gripping ends in lapped relation to the body portion of the device.

Fig. 8 is a side view of Fig. 2.

the like to prevent twisting or kinlv Serial. No. 595,656.

F lis a plan view of the device in the term ot a flat plate, with gripping tongues out theretron'i.

Fig. 5 is a section on the line 5-5 of F 4:.

F g. 6 is a plan view of the device, also l in the form of a flat plate, with its ends shaped to comprise gripping members, and

Fig. 7 is a section on the line 'Z-7 of Fig. 6.

In one form of my invention, as shown in Fig. 1, it may be composed of still wire, in a single lengtl'i, bent to provide the oppcsite folds 1., 2, and having outer length portions 3, 4 with an intermediate length portion 5, the outer length portions 1, 2, each being shaped near their ends into loops or :anrvatures 6, closed by reason of their terminal ends tensionally abutting against the respective folds l and 2. The wire length portions 3, iand 5 lie normally in adjacent parallelisii'i, so that the loops 6, which are adapted to receive a cord such as a telephone cord, may tensionally clamp the cord against the length portion 5, respectively at opposite sides and ends thereof. It is by thus clamping a telephone cord at separated points along its length that a loop is formed in the cord which may comprise the normally unused slacli' thereof, thereby preventing the cord from twisting and becoming kinl'ied.

Obviously the lengthof wire employed by me in producing this form of my device must be sufiiciently stout or stiff 'in its preformed shape to enable the length portions 3 and l to lie against length portion 5 under tension which is capable of gripping the telephone cord, at the loops 6, tightly enough to prevent slipping oi the cord; although the tenacity of the gripping pressure must not be too great to prevent the cord from being drawn manually through the loops for purposes of lengthwise adjustment.

The tensional grip is so shaped and arranged that while it functions properly it can in no way injure the covering of the telephone cord. On the contrary, the use of the device materially lengthens the life of both the telephone wire and its covering, by preventing the twisting or kinking which otherwise would occur in normal use or" the receiver under the present method of operation. 7

In a modified form of the wire device, shown in Figs. 2 and 3, the end loop portions 7 may normally lap over upon the folds 1 and 2, to "thereby enhance the tensional grip thereof.

It will be appreciated that in order to fit the device to the cord the loops 6 or '7 are to be manually spread open for the reception of the cord.

In another form of my invention shown .in Figs. 4 and 5 the device may consist of a flat strip of material 8, having spring tongues 9, 9, cut therefrom at its opposite ends, these tongues 9, 9, being curved as at 10, to comprise sockets for the reception of the cord, the tongues also having their ends 11 outwardly flared to provide convenient means for the entrance of the cord into the sockets.

In a still further modification, shown in Figs. 6 and 7, the strip of fiat material 12 there represented has its opposite ends turned over, oppositely, toward the respective sides of the strip, in the form of spring hooks 13, 13 to provide the cord engaging means which comprise the essential feature of my invention.

Variations Within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.

I claim:-

Non-twisting means for slack length portions of cords comprising a piece of stout spring wire folded into three parallel members lying approximately in the same plane, each of the outer members having its and bent to co -act with an adjacent end of the central member, thereby forming a loop to receive and tensionally engage a cord.

Signed at the borough of Manhattan, in the city, county, and State of New York, this 16th day of October, 1922.

JAMES E. SIMPSON.
