ARTHUR P. BANNISTER, or oRANs'roN, RHODE ISLAND, ASSIGNOR TO THE BAssET'r JEWELRY COMPANY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that I, ARTHUR P. BAN- MsTER, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Clasps, of which the following is a specification.

My'invention relates to cla'sps or fasteners adapted for use upon belts and bands.

The essential objects of my invention are to afford an adjustment of the band or belt without the entire disengagement of the clasp parts; to effect this end without pressure of the band or belt against the edge portion of the face plate, whereby the exterior of the belt face is worn, weakened, or defaced; toinsure a grip upon the band at various points more or less remote from each other, whereby a maximum of security is attained, and a groove or continued line of indentation of the inner face of the band is avoided, and no impairment of strength ensues; to enable the clasp members to be entirely disengaged from each other at will: and to attain these ends in a structure which is light, strong, and inexpensive to manufacture.

To the above ends essentially my invention consists in such parts and combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification, Figure 1 is a plan perspective view of a clasp attached to a complete belt embodying my invention, Fig. 2, a top plan view of the clasp and adjacent parts, Fig. 3, a longitudinal section of the same on line 3-3 of Fig. 1, Fig. 4:, a similar section of the same showing the clasp members in open or adjusting position, and Figs. 5 and 6, rear perspective views of the clasp members in detail.

Like reference characters indicate like parts throughout the views.

In detail the body member 7 of my clasp comprises an oblong curved face plate 8 provided with rearwardly directed flanges 9 upon its top and bottom edges. Fixed to the rear portions of the flanges are transverse bars 10 and 11; the latter preferably flat, and the former preferably cylindrical, in cross-section. The bars are spaced from Specification of Letters Patent.

each other near opposite end portions of the such a width as to pass easily between the flanges 9 as a sliding fit. Upon its outer end is an attaching loop 1 1, and integral with its inner end is a broad hook 15 whose resilient beak 16 is provided preferably with an inward bend 17. The bight 18 of the hook is adapted to form a seat for the bar 10. The hook is centrally positioned upon the end of the plate 13. Integral with the end of the plate 13 at each side of the hook 15 are hooks 20 with short, straight, rigid beaks 21 disposed at a greater angle to the plate 13 than is the beak 16, and in whose bights 22 also is adapted to be seated the bar 10.

In the drawings, 23 represents a band or belt, one end portion 24: of which slides loosely along the rear surface of the face plate 8, and whose other end portion 25 carries a loop 26 passing through the loop 1a of the plate 13.

The clamping member 12 is independent of the body member"? in construction, and when it is desired to apply the belt these parts are manually inter-engaged as shown in Fig. 3. This is the normal engaged or wearing position. The hooks 15, 20, partially surround the bar 10. The free end of the beak 16 engages the belt portion 24: near the end of the faceplate 8; the free end portion being outwardly inclined somewhat by virtue of its intermediate bend 17 The length, resiliency, and shape of the beak 16 permits a gripping effect of its end upon the belt despite the curved character of the face plate 8. The beaks 21 also effect a gripping action, but their action is effective at points in the rear of and at each side of the beak 16. Hence there is exerted a grip upon the belt at three separate points remote longitudinally of the belt. The long resilient beak 16 acts first in order upon the belt, thus holding it preparatory to the contact of the rear beaks. The inclination of all the beaks is such as to prevent longitudinal movement of the belt portion 2 1.

If after the belt or band is applied to from each other both transversely and the body it is desired to lengthen or loosen the same, the member 12 is tilted somewhat on the bar 10 relatively to the member 7 thereby raising the beaks out of contact with the belt, as shown in Fig. 4. Thereupon the belt portion 24 is freed and may slide the necessary distance to enlarge the circle of the belt the desired extent, and then permit the clasp members to assume their original positions of engagement.

What I claim is 1. In a belt clasp, the combination of a face plate, lateral guide flanges on the plate, a transversely disposed bar engaging the flanges and spaced from the face plate, a clamping plate, a belt engaging loop on one end of the clamping plate, a hook on the other end of the clamping plate independent of the bar, engaging the bar and adapted to co-actwith the face plate, and auxiliary hooks upon the clamping plate disposed at an angle to the first hook.

2. In a belt clasp, the combination of a face plate, lateral guide flanges on the plate, a transversely disposed bar upon the flanges spaced from the face plate, a clamping plate, a resilient hook upon the clamping plate removably engaging the bar and adapted to coact with the face plate, and auxiliary rigid hooks upon the clamping plate.

In testimony whereof I have aflixed my signature in presence of two witnesses.

ARTHUR P. BANNISTER.
