To all whom t may concern:

Be it known thatV I, CLARENCE A. COOK, of the Ordnance Department, United States Army, a citizen of the United States and' The invention described herein may be used by the Government, or any of its of-v ficers or employees'in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon.

end clip .for binding webbing and4 the like and to the process by which theend clip is shaped and 'applied to the webbing. v

It has been found that by making the closed portion of the initial cupeshaped clipv flat instead of curved, and upon pressing such a clip on the webbing, an inward curved portion is automatically formed which tends to compress the webbing within the Aclip thereby aiding materially in securely fastening the clip tothe webbing.

In the following specification reference is made to the accompanying drawings, in`

Figure l is a side elevation of the webhing such as a woven belt with the cup-V shaped clip in initial position thereon, the clip shown in section. A 1 Fig. 2 is a side elevationof the webbing with the clip partially compressed;

Fig. 3 is a side elevation ofthe clip com-'l pletely compressed to final position; and l Fig. 4 is a sectional view of the webbing and clip shown in Fig. 3. Y Y Y The numeral 1 represents a-strip of woven fabric or the like suchas is commonly used in making belts. straps. etc. The numeral l a strip,

2 designates the end clip for such in its initial drawn condition. Y

The first operation inV accomplishing my invention is that of drawing a piece of brass, 'or other suitable material, preferably by means of a die of such shape as to produce a cup shaped clip like that shown in Fig.

1, and then bending the open end of the y cup inward, It will be noted. that the clip .tooth 5 for engaging the fabric.

and .also that the'end of the sides or body portion 4 is bent inward by otherwise so as to form an inturned edge or rllhe end of the strip of'fabric is folded over as indii, cated at 6 so as. to: fit within the inouth .of the cup-shaped clip. Pressure is know applied tothe annular surface 4 preferably in' a direction at right angles tothe directiony indicated by the arrows; (Fig. l) so that .the

spinning or i '2 resulting fromA this tope-ration formed I. with a flat b ase 3, and with the annular sides A4 at approximately right angles to the Vbase so i this pressing operation and it will Vbe noted Y that the fold 6 of the fabric is flattened out so'as to fill the vspace'provided by the elonvend of fold 3. and the tooth 5.` This Vgivesl the clip a veryk firm gripon-the fabric by increasing the density thereof between the fold 3 and tooth 5 so that it yisalmost impossible to pull the clip from the fabric without first tearing the samel Y Y Having thus described my invention, what Y I claim as new and desire to secure by Let# ters Patent, is: i

l. The process of securing a clip to a strip Y of woven material which consists inY form`- ing apiece of metal into a cup-shaped clip having a flattened closed end, inserting a` folded end of the strip into the open end `of the rclip Yand compressing' the metal until -7o gation of the opening in the cup. A fur n ther'pressure givesA the result shown inFigs.'` Y

3 and 4, the-tooth 5 being pressed into the theflattened end portion is folded inwardly. Y, Y 2. The process of securing a clip to a strip Y ofwovenmaterial which consists in form- Y ing a piece of metal into a cup-shaped clip having a flattened closed end, bending in- -wardly the terminal `edge at the open end of the clip, inserting a folded end of the strip into the clip and compressing the 'metal' until the attened end portion is folded `inwardly against the material included within the clip. Y

3. An end clip for woven material which comprises a cup shaped body portion having a {iattened closed end and the periphery of the open end spun inwardly.

4. An end clip for woven Vmaterial Comprising a cup Shaped member having a flattened closed end and an inwardly spun edge y atiits open end, the closed end adapted to buckle inwardly when the clip is flattened upon the material. Y

5. An end clip for fabrics having a closed rendl folded inwardly between the sides of rthe clip.
