i B C E. I l 1 Application filed March 15,1924. Serial No. 699,557. I

Our present invention relates to buckles and clasps and more particularly to belt buckles .of the kind used on personal apparel and it has for its object to provi de' a buck-1e having improved means for securing the belt at both ends without the necessity of perforating it which means are conveniently ope'rable and uniformly effective, Further improvements are directed toward arrangements in this connection whereby. the free end of the belt can be inserted in the buckle with the greatestfacility.- To t-hese "and other ends the invention resides in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a top plan view of a buckle and fragments of the end portion of a belt the same being constructed in accordance with and illustrating one embodiment of our 7 spring bears against the aw plate 8 at 12 tion therethrough showing the free end of the belt in clamped position;

Figure 8 is a view similar to Figure 2 with the free end of the belt released and showing the manner in which it is originally inserted and Figure 1 is an enlarged elevation of the inner side of the buckle alone.

Similar reference numerals throughout the several views indicate the same parts.

In the present embodiment of the invention the buckle proper comprises a curved plate 1 having convexity in two directions. The permanently attached end of the belt is indicated at 2 and the free end at 3. On the top and bottom edges of the buckle plate are flanges 4. At one end of these the buckle plate is spanned in spaced relationship to its inner side by a shaft 5 mounted in the flanges and having one end flattened as shown at 6 in Figure 1 to prevent it from it is so proportioned with reference to the distance of the shaft 5 from the buckle plate that as it rotates on the shaft its gripping surface very gradually; approaches the surlfaceof the plate swinging in adirection towardthe body of the belt, that is, to-ward the tip of the'buckle.

The beltis slipped into the buckle between the buckleplate and the'shaft 5 and beneath the jaw plate 8. The latter is then pressed down against it and due to the curvat'ure and "the swinging mount of the jaw plateit grips the belt end and jams itiagainst the buckle plate. The. harderthe belt is pulled upon the stronger is this.' .ja'mming action.

In order to jawplate with the belt with sufficientfrictional contact to cause the belt to rotate the jaw plate into' jamming position, we pro-' vide spring means for actuating the jaw plate in such direction. In the present eni- ,bOCllllIGIlll an intermediate portion of the knuckle-7 is cut away at 10 and a spring 11 is coiled about the shaft 5. One end of the 8 can be turned back easily with the fingers.

In fact a groove 14: on the knuckle 7 roughens the latter sufficiently to give a purchase for the fingers that will turn the jaw from the knuckle.

The other end 2 of the belt is held by a clamping member 15 having trunnions 16 turning in the flanges 4. Its edge is serrated at 17 and it is of such a length that when it is turned at right angles to the buckle plate 1 it bites into the material of the belt end 2 and clamps it firmly against the plate. At this time, a lever portion 18 by means of which it is manipulated is inclined toward the center of the plate in the position shown. In order to insure the free passage of the end 3 of the belt beneath the jaw plate 8 and to the inner side of the clamp 15, we provide a thin curved guide plate 19 having an offset 20 at its rearend in which the lever 18 may seat itself so that it insure'the engagement of the 7 forms substantially a continuation of the to a knife edge at 21 where it contacts with the buckle plate and it is secured in place to tightly hug the plate by perforated ears 22 that lie against the flanges l and are secured'by the shaft 5.

lVe claim'as our invention:

1. In a buckle, the combination with, a buckle plate, of a shaft spanning the same,

a a curved, swinging jaw plate having a knuckle portion on the shaft and adapted to jam a belt against the buckle plate, said,

knuckle portion being cut away to expose a, portion of the. shaft, and. a spring surrounding the shaft within the cutaway portion of the knuckle and acting to move the jaw plate to operative position.

a 2. In a buckle, the combination with a buckle plate, of a shaft spanning the same,

a curved, swinging jaw platehaving a knuckle portion on the shaft and adapted to jam abelt against the buckle plate, a spring on the'shaft acting to, move the aw plate to operative position, and a finger gripjon the knuckle" portion wherebyeit may be actuated- ."against its spring.

3. In a buckle, the combination with a buckle plate and a swinging belt gripping member adapted to pinch one end of a belt against the plate, said member guide plate being having a relatively angularly disposed operating portion, of a curved swinging jaw plate adapted to jam the other endcof the belt against the buckle plate, and a guide plate extending from the surface of the buckle plate in the region of the jaw plate tion, of acurved swinging jaw plate adapted to jam the other endof the belt against the buckle plate, a shaft therefor spanning thebuckle plate, and a guideplate extending from the surface of the buckle plate in with the gripping member' to guide said last mentioned belt end past the latter, said provided with ears by which it is mounted on the shaft.

the region of the jaw plate into cooperation CHARLES H. sAMPsoNg I I JAME S'Ll WHITLEY.
