Specification of Letters Patent.

Patented Aug. 8, 1922.

To @ZZ whom t may concern.:

Be it known that I, Jaime P. KELLY, a citizen oi' the United States ot America, residing at New York city. New York county, N. Y., have invented a new and useful Cord rfip, of which the following is a speciiication.

My invention relates to improvements in devices of the character set forth in my Patent #1,392,339, dated October- 1921. The main object or" my present invention is to provide a simple and inexpensive form of construction, the parts or which may be readily assembled on the end oi? a cord and securely held in place but readily separable when desired.

In my former patent l have illustrated forms or' tips in which there are central and lateral gripping members.

My present invention contemplates the use of a sleeve and a clamping member with a head provided with a recess or perforation into which an instrument such as a pin may be inserted for holding the head whilethe sleeve is pulled along the cord so as to separate the parts. The clamping member may engage the cord in any suitable manner, but I have illustrated herein as one *form a particularly simple construction, in which the clamping member is in the form of a pin Vadapted to be stuck through the cord transversely and bent over and held by the sleeve.

Fig. 1 is a side view of one form ot cord tip embodying improvements of my invention. Y

Fig. 2 is a perspective view showing the sleeve slipped back along the cord.

Fig. 3 is a view of the clamping member before it is bent over.

Figs. 4 and 5 are perspective views of other Jforms of lateral clamping members having instrument receiving recesses in their heads.

Fig. 6 is a perspective view of a central tip clamping member with a coiled head and recess.

Fig. 7 is a plan view of another form of clamping member with side jaws and a recess in the head.

Fig. 8 is a longitudinal sectional view of another form of cord and tip of my invention.

Fig. 9 shows the parts of another form of tip, the sleeve being in section.

The cord or string 10 may be oi' any suitable material, such, for instance, as braided, twisted, or woven threads such as are commonly the like. The particular cross-section such as round. oval, or flattened is immaterial. The sleeve l1 is in the form of an open ended tube of suitable cross-section, and will usually be or" somewhat less transverse internal area than the end oit the cord so that it will t snugly. rThe clamping member is in the form of a pin having a shank 12 and a head 13. The pointed end or tip 14 of the pin is adapted to be stuck through the cord 'and then bent over as shown in Fig. 2. l/hen the sleeve 11 is pulled out toward the end it compresses the parts 12 and 14 into the sides of the cord and thus increases the gripping eiiect. The main shank of the pin may be provided with barbs or tongues 15 adapted to stick into the cord and increase the gripping effect. The back or shoulder 16 of the head may be tapered or inclined so as to assist in centering the head with respect to lthe end of the sleeve 11.

To remove the tip, for instance for the purpose of shortening the cord and reapplying the tip, it is necessary to slide the sleeve 11 alongthe end of the cord away from the head 13. When the partsV are made so as to fit together snugly, this operation et separation is sometimes rather difiicult. To facilitate the separation therefore provice a recess such as 17 into which the point 'of some instrument such as a pin may be inserted to hold the head and clamping member while the sleeve is slipped vback into the position'shown in Fig. 2. It will be obvious that the end or tip 14 may then bev withdrawn from the cord. To prevent interference with this withdrawal, the end or tip 14 is preferably left smooth. To re-apply the device, the cord is cut at the desired point and the tip 14 of the pin pushed through the cord and bent over as shown in Fig. 2, and the sleeve 11 pulled down to the end against the rear shoulder of the head. This provides a very secure tip which cannot become disengaged accidentally.

In the form shown in Fig. 4 the shank 12 is flattened and adapted to lie against one side of the cord. In this form t-he barbs or tongues 15 are formed by punching small triangular holes. The recess 17 instead ot being entirely in the exposed part of the head may be in the edge of the head so that less of it will be exposed beyond the end of the sleeve when the parts are assembled. As the tapered point of an ordiemployed in making shoe strings and nary pin or needle (not shown) is inserted into the outer part of the recess 17'; it Will begin to force the sleeve avvay from the head.

In the Vform shown in Fig. 5, the barbs or teeth 15""are formed onthe edges ot the shank of the clamping member. f

The form of device shown in Fig. 6 has a shank 12'?1 adapted to `be inserted into the center ot the end of; the cord, and the head 13? is formed by ooiling the Wire so as to leave an instrument receiving recess 17a.

The form of device shown in Fig. 7 is termed by bending a piece of Wire or strip of material; so as to provide two` jaws l2", one of Which is preferably longer than the other soas to facilitate assembly of the sleeve over the jaws. The head portion 13b is formed so as to provide a recess 171 for the insertion of a holding instrument-` In, the form of device shown in Fig. 8, the clamping or gripping member may be stamped from sheet metal with its head 13 so. shapedi as to leave` a recess 17c at the end of the sleeve 11.

In the form` shown in Fig. 9,.the tip 14d ot` the shank oi' the gripping member is long enough to project of the sleeve 11d so that pressure may be applied at this end through the body `ot the cord to start the separationmovement of the sleeve with respect to the gripping member. In `this ease, the recess 17d is normally concealed by the end of the sleeve, but is exposed bypressing on the opposite end;` 14s so that a pin may be inserted into the recess 17d `for completing the separation movement* I claim:-

1. A cord tip device comprising a head,- ed pin with a shank for embracing one side of the end of a cord, said pin having another portion or extending transversely through. the. `cord" and al tip portion cona bit beyond the end nected to the transversely extending portion 3. A cord tip comprising a gripping member With a head at one end anda bendable tip adapted to be inserted through the end ot a cord, and a sleeve adapted to slide along the end of the cord for holding said member and its tip in place.

1l. Acord tip comprising a gripping member having a head With an instrument receiving recess and a bendable, portion adapted to be passed through the end oi' the cord and a sleeve holding the parts in place.

5. A cord tip comprising a gripping element having a head With a tapered centering shoulder and a toothed shank adapted to lie. alongside theend of the cord, and a sleeve adapted to slide along the cord and to hold.` said shank in place, said sleeve abutting against said tapered shoulder When said parts are assembled.

6. A cord tip comprising a gripping mem* berhaving a shouldered head With an instrument receiving recess and a sleeve embracing the endV of a cord and holding said gripping member in place, said sleeve abutting against said shouldered head.

"t". A cord tip comprising a gripping member having ahead vvithl a transverse passage for receiving the point of; a holding instrument and a shank for engagingy the end of a cord,'and a sleeve embracing the end of' cord adjacent Said heald for holdin@r sai Ori 1n mem er 1n ace.
