UNITED STATES FATENT QFFEEU JAMES A. STORM, OF ST. LOUIS,- MISSOURI.

FLAT-HOOK FASTENER.

Application filed February 20, 1920. Serial No. 360,195.

To aZZ to 700m it may 0012069 21,:

Be it known that 1, Lines A. STORM, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in F lat-Hook Fasteners, of which the following is a specification, reference being had to the accompanying drawings.

This invention pertains to detachable and adjustable hook-fasteners, for use upon or in connection with narrow bands, tapes, ribands, belts, straps and the like, where it is desirable to employ an adjustable,combination hook-fastening adapted to unite two ends or edges together as smoothly, evenly and flatly as possible.

The objects of this invention, therefore, are to provide in a simple, efficient and durable form a hook fastening of this nature, one end of which may be permanently attached to one end of the band, while the other end may be adjust-ably or detachably connected with the other end of the band; and to make the said device in a form which will lie perfectly flat against the band or other material on which it is used, and so there will be no appreciable increase in thickness at the point of juncture.

With these objects in view, attention is called to the accompanying drawings, wherein Figure 1 is a perspective view showing one of the fasteners employed upon a small band for the purpose of detachably and smoothly joining the ends;

Figure 2 is a similar perspective detail of the fastener and band showing the position of the prongs thereof mounted upon a band, but not yet bent down;

Figure 3 shows a metal blank from which the fastener is stamped;

Figure 4 shows the fastener as stamped out of the thin metal blank shown in Figure 3- Fighre 5 shows the fastener detached from the band, but with prongs bent down in the same position as when properly clinched upon the band.

Figure 6 is a perspective view of a modified form of construction wherein the length of the prongs are varied from the form shown in the other figures.

In the preferred construction shown in the drawings the fastener is stamped from a thin metal blank 1 to the form 2 shown in Figure 4:, same embodying the back or base 3, the lock prongs 5 and 6 and the hook prong t. The lock prong 6 at one end of the back 3 is struck outwardly from the back portion 3, and extends, until bent over, straight out in axial alignment with the back 3, while the lock prong 5 is struck inwardly from the back 3, forward of the prong 6, preferably shorter than the prong 6, and likewise extends, until bent over, straight back in axial alignment with the back 3 and prong 6. The hook prong 4 is struck outwardly from the opposite end of the back 3, is preferably somewhat longer than the prong 6, and extends, until bent over, straight out in axial alignment with the back 3 and the prongs 5 and 6.

In mounting the fastener upon the band 7, the prongs 5 and 6 are bent straight up perpendicular to the back 3. These prongs 5 and 6 are then forced through the end 8 of the band 7 and are then bent down, both forwardly in the same direction and pressed firmly down upon the band 7, thus locking the fastener permanently upon the band 7. The hook prong 4 is then bent up and back to form the inwardly turned hook shown in Figure 1, ready to engage anyone of the eyes 9. formed through the other end 10 of the band 7. When the band is properly adjusted to the right length by locating the hook prong 4 in the proper one of the eyes 9, the free end of the band may be cut off just forward of the hook 6 so that the ends 8 and 10 will not overlap but will fall flatly into alignment.

This fastener therefore affords a simple and efiicient means for detachably connecting the ends of a band, or the like, in a flat and continuous manner, and without any appreciable increase in the thickness of the joint over the adjacent band.

While I have herein described acertain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.

What I claim to be new and patentable is:

A. flat hook fastener for bands, same being stamped from a thin metal blank so as to form an elongated base portion, a lock prong extending from one end of the base portion, in axial alignment therewith and adapted for piercing through an end of the band and bending down thereupon; another and shorter lock prong struck from the base portion adjacent and in axial alignment with sameheing adapted for bending over toward the first mentioned 100k prong, and likewise the 100k prongs to form a hook to detach- 10 adapted for piercing through the same end ably engage the other end of the band.

of the band and bendin down thereupon in the same direction with the other prong; JAMES STORM and a hook prong extending from the oppo- Witnesses:
