nnrrn 1 TATi i BACK-BAND BUCKLE.

To all whom it may concern:

Be it known that I, JAMES A. Hanson, citizen of the United States, residing at Aubrey, in the county of Denton and State of Texas, have invented certain new and useful Improvements in Back-l3and Buckles, of which the following is a specification.

This invention has relation to backhand buckles and new and useful improvements therein.

The object of the invention is to provide a buckle which will hold in position either on web or leather backhand and so arranged that an increased. pull will act to tighten the engagement of the buckle with the backhand instead of loosening the same and in carrying out this feature will also provide teeth engaging on both sides of the backhand in staggered relation.

Finally the object of the invention is to provide means of the character described that will. be strong, durable, efiicient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out of working order.

l/Vith the above and other objects in View, the invention has relation to certain novel features of construction and operation, an example of which is described in this specification and illustrated in the accompanying drawings, wherein:

Figure 1. is an elevation of the buckle, Fig. 2. is a vertical section on the line m00 of Fig. 1. showing a portion of the backhand in the buckle, and Fig. 3. is a side elevation of a portion of the buckle and backhand.

In the drawings the numeral 1 designates the buckle and 2, the backhand. The buckle is formed of any preferred metal and suitably finished.

In constructing the buckle a broad base plate is provided. The base plate at its lower end is contracted to form a central depending loop or hook This book is produced by bending up the metal and directing it over the contracted portion as shown in Fig. 2. The end of the hook is bent slightly inward to form a spring looking tongue for the purpose hereinafter described.

At the upper end and on opposite sides of the base plate, ears 6 are provided and proj ect at substantially right angles to the plate. These ears are arranged to receive the trunnions 7 of a flat clamp 8, permitting Specification of Letters Patent.

the clamp to be swung open to receive the backhand and close to hold it in the buckle. The clamp is also contracted at its lower end to produce a depending central portion which terminates in a stop 9 directed inwardly from the clamp and adapted to impinge the base plate at a point adjacent the spring tongue 5. The lower face of the stop is roughened or provided with teeth as indicated at 10 and with which the end of the tongue 5 engages to lock the clamp in position. It is obvious that by pressing inward on the tongue, the clamp is released and may be swung outward.

Transversely of the base plate a curved opening 11 is provided and is of suflicient width to freely receive the backhand 2. Along the upper edge of the opening teeth or projections 12 are provided. These teeth are bent slightly so as to project toward the clamp. In the clamp similar teeth 13 are provided and bent slightly inward toward the base plate. However the teeth 13 are so disposed as to project in staggered relation to the teeth 12 and with their points substantially over the intersections of the teeth 12. This disposition and arrangement of the teeth is very important and is one of the best features of my invention for the reason that when the backhand is passed through the buckle as shown in Fig. 2 the teeth will bite into it on both sides and the teeth on one member will have a tendency to force the backhand into the spaces between the teeth of the other member and thus firmly hold the buckle against sliding or displacement on the backhand irrespective of the fact that the backhand is made of leather or webbing. It is also obvious that either an upward pull on the backhand or a downward pull on the buckle will cause the teeth to more firmly engage the backhand.

What I claim is:

The combination in a backhand buckle, of a base plate flat throughout its length, ears turned up from the plate at each side of one end, the opposite end of the base plate being cut away at each side, a hook formed from the cut away end of the plate and bent thereon, a spring locking tongue extending inward at an angle from the hook, the base plate having a transverse opening with one curved side and one straight side, teeth projecting from the plate into the opening on the straight side, the teeth having their points bent upward, a flat clamp plate hav- 5 ened face engaged by the spring locking ing trunnions at one end engaging in the tongue.
