This invention relates to a belt buckle for use in connection with any belt or band to which it may be found applicable by those skilled in the art.

Briefiy stated, the improved buckle comprises a backing plate with slotted ends and a maintenance or retention boss, together with a companion clamping plate or slide having means for cam co-aotion with the slots and a hook to accommodate an eyelet fastener, and an elongated belt retaining opening for cooperation with the aforesaid boss.

In carrying the principles of the invention conception into actual practice through the instrumentality of the aforesaid structure, I have evolved and produced a simple and economical accessory which is not permanently connected to the end of the band but rather has adjustable connection therewith to permit the buckle to be quickly adjusted and maintained in the desired adjusted position.

I am aware of the fact that many types of buckles involving the cam pressure and clamping principle are in vogue and are found in similar With a general knowledge of this, I have perfected a specific buckle constituting what I believe tol be a unique contribution to the trade and the art in that it is structurally distinguishable, positive and dependable in action, and otherwise well designed and balanced to accomplish the desired result in a highly satisfactory manner.

In the drawings:

Figure 1 is a view showing one band-end in full lines and the companion band or strap end in dotted lines, together with the improved buckle associated therewith.

Figure 2 is a longitudinal sectional view of the structural assembly shown in Figure 1.

Figure 3 is a plan View of the sheet metal blank from which the backing plate is constructed.

Figure 4 is a section taken on the plane of the line 4 4 of Figure 1.

Figure 5 is an outside elevational View of the arrangement illustrated in Figure 1 showing the relationship of parts more plainly.

igure 6 is a section taken approximately on the plane of the line 6 6 of Figure 5.

Figure 7 is a perspective view of the slidable clamping plate.

Figure 8 is an end View of the slotted flange-end of the backing plate.

In the drawings, in Figures 1, 2 and 5, a band is designated by the numeral 9. One end portion of a complemental band or the like is shown in the drawings andis. designated by the reference numeral 1,1.. This band or strap end 11 is prolvided with an eyelet designated by the reference numeral 12 and also shown in dotted lines.

The improved buckle comprises two primary parts; namely the relatively stationary section 13 and the relatively movable or adjustable section 14. The first-named section 13 comprises a rectangular backing plate 15 constituting a part of the blank shown in Figure 3. As seen in the last-named figure this backing plate is provided with a longitudinally elongated outwardly pressed portion which defines a maintenance hump or boss 16.

The end portions of the plate are bent up at right angles on the score or fold lines 17 to form a pair of duplicate end flanges 18 having inclined cam or binding slots 19. The complemental or companion section 14 is shown in Figure '7 and comprises a suitably proportioned and Shaped slide plate 20. This has a triangular end portion whose apex part is formed with an inturned keeperl hook 21 andI an associated aperture 22, the hook being fashioned to permit quick releasable connection of the eyelet fastener 12 thereto as shown in Figures 2 and 5. The aperture 22 is obviously nothing more than a clearance hole to facilitate connection and disconnection of the features 12 and 21.

The plate is provided with integral outstanding cam lugs 23 fitted slidably in the cam slots 19 and the plate is further formed with an elongated rectangular adapter hole or opening 24 which is shaped to correspond with the aforementioned maintenance boss 16. The opening 24 is slightly larger than the boss as is evident to permit the material of the band or belt to be crimped over the boss as indicated at 25 in Figure 2 whereby to force the material into the hole 24 so that it is securely held between the two plates 15 and 20 when they are bound firmly together by the customary cam clamping action.

It is obvious of course, that the plate 20 is In the present buckle arrangement the clamping u action is uniform, positive and dependable, such as to firmly hold the belt vend l0 in place in the manner described. Likewise, the binding or clamping action is such as to' minimize damage to the belt, strap, or band, as thecase may be.

From the foregoing description it will be observed that the principal vnovelty is predicated upon the particular construction and arrangement of the buckle irrespective of the structure with which it is used. Such a buckle is applicable to belts, body encircling bands, straps, and similar accessories. In particular, a buckle of this type may well be used as a back-band buckle in conjunction with plow gear and wagon harness by merely changing the position ofv the buckle in the drawing from a horizontal to a Vertical position to accommodate a trace or the like (not shown). Needless to say, however, the buckle may be used for any purpose for which it is found satisfactorily applicable.

These and rother structural, commercial and economical features havev doubtlessr been madey apparent from the explanatory description'fwhen read in conjunction with the illustrative drawings.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

'.tWeen said flanges, said clamping plate being provided with opposed lugs having slidable cam co-action with said slots, said clamping plate being formed with a retaining hook, and an elongated adaptation hole for co-operaton with said boss to permit a band end to be firmly clamped between the plates and forced by the boss into said adaptation hole.
