Another object of the present invention is toprovide a superior slide-buckle of the character referred to in which the major portion of the buckle may be substantially concealed by the strap-portion which it grips.

A further object of the present invention is to, provide a superior slide-buckle of the type lreferred to and which has its elements so constructed and arranged as to enable a strap to be gripped against the front surface of theframe or body-member rather than against the rear taken on the line 8--8 of Fig. '7, but on a larger scale; l

face thereof, so that a relatively-small grippingmember may be substantially all that interrupts the otherwise apparent continuity of such strap.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art and which are not claimed in any separate application.

The buckle of Figs; 1 to 6, inclusive The particular embodiment of the present invention shown in the figures referred to, comprises a body-member or frame generally designated by the reference character 20, and a gripping-member 2l slidable lengthwise of the said body-member. f

The body-member 20 above referred to, includes a substantially-flat front-panel 22 from the respective opposite side-edges of which rearwardly project longitudinally-extending sidewalls 23-23 coupled together at their outer ends by an integral outer end-Wall 24. Adjacent its outer end, the front-panel 22 of the body-member 20 is provided with a series of transverselyextending flutes 25 to provide a gripping surface for the retention of a strap,gin a manner as will hereinafter appear.

Adjacent its inner end, the body-member 20 is formed with a transversely-extending strapreceiving slot 26 having its outer wall constituted by the inner edge of an integral strap-attaching bar 21. Also adjacent its inner end and hence adjacent both the slot 26 and the bar 2l,

the movement of the gripping-member 2|, in a manner as will hereinafter appear.

Forwardly of its stop-ear 28, each of the two side-walls 23-23 of the body-member 20 slopes away from the strap-attaching bar 21 and away from the front-panel 22 thereof to provide each of the said side-walls with a rearwardly-facing nclined camming-surface 29 constituting-portions of the r rear-face. ofthe 'said body-member '20.

The body-member or frame 20 above referred to may be conveniently stamped up from sheet metal in an economical manner to provide a structure of adequate strength.

The gripping-member 2|...before` referred --to comprises a front gripping-bar"30,extending transversely across the front face of `thefrontpanel 22 of the body-member 26. Formed integral with each of the respective' opposite ends of the gripping-member 2| is one of'two. rearwardly-extending J-shaped side-arms 3|-3|.

Projecting laterally inwardly `fromthe rear- 'end of each of the side-arms`41-/41- is one of two cam-fingers 48-48 inclined with respect to the gripping-bar 46 to a'degree sufficient to cause the said gripping-bar' to extend' substantial parallelism with the 'fro`nt-panelf38 of the body- Each l of the lcam-fingers '48-48 thus, under normal conditions', has '.camrningfen- A gagement with the adjacent portion'lof. ther rear face of the rear-panel 39 to thus Cause/the ygripping of a suitable strap by-the gripping-bar 46 when the gripping-member 45 is 'moved toward the outer'end of the body-member 31.

To guard against Vthe =detachrnentof the gripping-member 45 by riding oil the outer end, of the body-member 31, the cuterend-Wall-l .of the said body-member is extended transverselybn each of the respective opposite sides` of'the .'s'aid body-member to respectively provide 'stop-ears 49--49 respectively engageable by theouter edges of the side-arms 41-41 of the gripping-member .45.

To guard against the demounting ofthe gripping-member 45 by movement inwardly and over the laminated strap-attaching bar 42, the respecf tive inner ends of the said body-member are projected transversely outwardly to provide stop-ears 50-50 respectively engageable by the inner edges of the side-arms 41--41 of the gripping memvber 45.

f As thus constructed and arranged, the slidebuckle illustrated in Figs. 7 to 10 inclusive has 'the same fundamental characteristics as the structureV illustrated in Figs. 1 to 6 inclusive.

The buckle of Figs. 11 to 17, inclusive l This particular slide-buckle includes a bodymember 5| which may be conveniently formed by.' molding the same from any one of a wide variety of synthetic resins.

\- back or front of the structure in a manner as will fully hereinafter appear.

The outer end of the body-member 5| is of semi-cylindrical form a's at 54, and the material of the said body-member is projected outwardly on each of the respective opposite sides at the said' outer end to provide stop-ears 55--55, for

thepurpose as will hereinafter appear. Adjacent the outer end of the body-member 5|,.the face 52 thereof is provided with transverse ilutes or` Slidable longitudinally of the body-.member 5| is a tubular `clamping-member 62 having two spaced-apart face-bars 63 and'64 extending in 'substantial parallelism with. each other ina directiontransversely of the body-member 5|, butin-"145 clined with respect to each other-in a direction lengthwise of the said body-member.` The-two f face- bars 63 and 64 are each:connected yat-their respective opposite ends to the other ofthe facelFor purposes of decoration, the face-bar-63zrnay,

if.l desired, be provided withv a-slot 66, as is shown especially well in Fig. 16 and the face-bar 64 `with any desired ornamentation, such for instance, as the monogram shown in Fig. 12.

The clamping-member 62 may be made Aof* any suitable material such, for instance,` as brass.

' As before indicatedthe.slide-bucklenow being y Ydiscussed'is reversible face-for-face -in.a manner as will be now more particularly described.

rThe vfree end 61 of the belt or-strapr6| may -be slipped between the inner `face of .the face- -bar 63 of the clamping-member 62 and the. face 52 of the body-member 5|, as isindicated in Figs. 11 to 14 inclusive, and clamped in place. by4 afrelative longitudinal movementbetween the bodymember 5| and the 'clamping-member 62 in such direction as will bring' the s aid clamping-member toward the outer or thicker end o f the said body-member. y

For purposes of description,l let it be assumed that the belt or strap 6| has its respective opposite faces differentially colored with respect to each other, thus, for instance, the face ofthe said belt against which the face-bar 63 of the clamping-member 62 is engaged might, for instance, be

black. The opposite'face of the strap might, for instance, be brown. Under thesecircumstances,

vif it is desired to have the outer face of the said belt or strap 6| show brown coloration, the said strap andthe slide-buckle structure may all be reversed into the positions in which they are shown in Fig. 15, and the freeend 61 of the said strap threaded inwardly toward the fixed end 60 between the face 53 of the body-member 5| and the opposite face-bar 64 of the clamping-member 62. This reversal is also indicated by broken lines in Fig. 14,.

Rsum

All of the three forms -of the present invention shown in the accompanying drawings and above described, ar'echaracterized by simplicity, reliability of action and relative unobtrusiveness of the buckle structure itself.

The invention may be carried out in other specic ways` than those herein set yforthy without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning land equivalency range of the appended claims are intended to be embraced therein. f
