18 Claims.

This invention relates to buckles and more particularly to a two-piece buckle for use in connection with suspenders, garters, lingerie, and the like. The embodiment disclosed herein comprises a so-called bail buckle having a frame and loosely mounted ball, which cooperate to clamp a tape therebetween when tension is applied to the tape.

Buckles have heretofore been proposed in which the upper span of a bail is adapted to crimp a strap or tape downwardly in a slot between spaced cross bars of a frame. Such buckles have several disadvantages, however, in that they cannot clamp thick tape and thin tape equally well. Also, they are usually made of metal with the cross bars in the same plane and a narrow link forming the bail. The narrow upper span of the bail merely pulls the tape downwardly and tends to tension the tape rather than to clamp it against the side of one of the cross bars, as is contemplated in the present invention.

In the present invention the bars defining the bail slot in the frame are offset relative to the median plane of the frame and are preferably comparatively thick bars substantially rectangular in cross section so that leverage applied to the lower span of the bail with the lower cross bar as a fulcrum tends to clamp the tape or strap between the upper span and the upper cross bar.

In the embodiment illustrated, the frame is formed of molded material, preferably a suitable plastic, and is provided with side bars and four cross bars defining three parallel slots, two intermediate cross bars being on opposite sides of the median plane so that opposite sides of these two bars are substantially in the same plane.

The upper span of the bail is sufliciently wide so that, when the body of the bail is extended through the intermediate slot and rests against the side of the lower cross bar, one edge of the upper span rests against the side of the other intermediate cross bar and the opposite edge of the upper span overlaps the upper surface of the lower cross bar. By this construction, when a tape is threaded through the bail in the usual manner and one end of the tape secured to the lower span of the bail, tension on the tape tends to pivot the bail about the lower bar as a fulcrum so that the edge of the upper span tends to clamp the tape against the side of the upper cross bar. Furthermore, the upper span of the ball is slightly angular to the body of the bail so that, when in clamped position, the surface of the upper span is substantially parallel with the plane of the buckle. The offset relationship of the cross bars of the frame and the construction of the bail to function in the manner specified enables the same effective clamping 'andeasy release of either a thicker thin taper It is an object or the present invention to provide a two-piece bail buckle Of molded material having a plurality of cross bars, intermediate bars of which define a; slot to receive the bail and in which the cross bars are sufiiciently thick to provide a vertical clamping surface on one bar above the central plane of the buckle and a fulcrum on the adjacent bar which fulcrum is materially below the median lane of the name.

Another object is to provide a bail buckle of the character described in whicha comparatively wide upper span of the bail is provided which span is suitable for decoration and will normally be substantially parallel with the plane of the buckle when the usual tension is applied thereto.

A further object is to provide a two' -piece buckle which will clamp and release either a thick 'or thin tape with equal facility and will be cheap to manufacture, convenient in use, and will not easily 'get out of order.

Further objects will be apparent from the specification and the appended claims.

Referring to the drawings in detail, the efnbodifil eflt illlls tl'atd cbffipfises a frame I having side bars 2, 'end' cross bars 3, and a pair of

inte'rmdiate cross

4 and 5. These er'oss; bars define outer slots 6 and 'l to receive a tape 8 and an intermediate slot 9 to receive a bail 10 which latter is loosely mounted therein as illustrated.

The bail It! comprises an upper span H and a lower span l2, the bail being formed substantially as illustrated in Fig. 4. This bail is preferably made of a single strip of sheet metal formed into a loop with the ends turned inwardly to form the lower span of the bail and preferably meeting on the central vertical plane of the bail at id. The major portion of the bail is materially narrower in cross section than the intermediate slot 9. However, at least a portion of the upper span is materially wider than the intermediate slot in the frame so that, when the bail is inserted in the slot as shown in Figs. '7 and 8, one edge of the upper span will rest against the side of the upper cross bar 4 and the opposite edge of the span will materially overlap the upper surface of the lower cross bar 5 as indicated at [3.

In the embodiment illustrated, the frame is formed of molded material and the side bars 2 are comparatively thick, as shown particularly in Fig. 6, and the inner surfaces of the cross bars are all in the same median plane 14 of the frame (Fig. 8). The fact that the frame is made of molded material is an important feature of the invention in that it enables the molding of thick cross bars with one of the cross bars below the median plane of the frame. These thick cross bars positioned as shown enable a particularly 'efiective clamping action of the tape when any thickness of tape is used, including very thin or very thick tape, and it avoids the necessity for positioning the upper span of the bail materially above the frame of the buckle and at the same time provides a more effective clamping action.

In applying the buckle to suspenders, for example, the tape 8 is threaded upwardly through the slot 6 over the

intermediate bars

4 and 5 through the bail and then downwardly through the slot 7. The free end of the tape is formed into the usual loop and secured to the lower span of the bail as indicated by the reference numera [5. It will be apparent that, when tension is applied to the tape and transmitted to the lower span of the bail by means of the tape end I5, the bail is caused to pivot about the lower cross bar 5 as a fulcrum and the upper span of the ball will tend to clamp either a thick or thin tape against the side of the upper cross bar 5.

When a relatively thick tape such as the tape 8 shown in Fig. 2 is used, the bail I is firmly held by engagement of the end I of the tape with the lower surface of the cross bar 5, so that the bail is restrained against upward movement even though the tension on the tape 8 is relieved. Such upward movement would of course completely release the tape and permit slipping through the buckle. Adjustment of the buckle may be accomplished, however, merely by holding the frame I and exerting on the tape 8 a sufficient longitudinal pull in either direction to overcome the resistance to slippage offered by the firmly held bail. When tension is applied to the tape 8 the clamping action, due to pivotal movement of the bail, occurs principally at or closely adjacent the upper right-hand corner of the bar 4, as shown in Fig. 2, and the tape is thus clamped partially against the side and partially against the upper surface of the bar 4. When in the clamping position shown in Fig. 2,

the upper span H of the bail IQ assumes a position substantially horizontal with the plane of the buckle, thereby contributing to the attractive appearance of the buckle.

In Fig. 3 the buckle is shown as applied to a very thin tape 8, and it will be observed that this very thin tape is firmly clamped between one edge of the upper span of the bail Ill and one side of the bar 5, the tape at the same time being tensioned over the upper surface of the bar 5. Although buckles of this type, intended for use with tapes on the order of thickness of the tape 8, would not ordinarily be used with tapes .as thin as the tape 8, the buckle construction is such that a satisfactory clamping will be obtained while at the same time permittingready adjustment even with paper-thin tapes.

While I have shown particular embodiments of my invention, it will be understood, of course, that I do not wish to be limited thereto since many modifications may be made, and I, therefore, contemplate by the appended claims to cover any such modifications as fall within the true spirit and scope of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
