3,091,141 FABRIC-FACE) BELT-BUCKLE FORE/ENG DEVICE William H. Decker, Chicago, 111., assiguor to Maxant Button 8: Supply Company, a corporation of Illinois Filed Get. 26, 1959, Ser. No. 848,579 10 Ciaizns. (Cl. 795) This invention relates to a device for forming fabricfaced buckles for a variety of uses such as garments, hats, shoes, and upholstering, especially by the individual professional or do-it-yourself workman.

For individually-tailored garments, having belts, it is frequently desired to have the metal base for such buckles faced with the same fabric as, or contrasting with, that from which the garment is fashioned. Similarly, hats and other items may also be trimmed with fabric-covered buckles. This is done generally where only one such buckle is required.

For years buckle bases of nearly every imaginable contour and size have been available in stores supplied by the manufacturers of dressmalc'ng accessories. These variously-shaped buckle bases generally comprise two metal stampings with flanged perimeters so dimensioned that one part nests within the other part. More often than not, these base parts will have cross bars whereon to hinge a tong.

Heretofore, the only known means and method by which the desired fabric-faced buckles could be made by hand was first by adhering a piece of fabric over the outer face of the larger of the buckle base parts with the fabric perimeter overlaying the inner face of the base part and subsequently superimposing the other base part on and pressing it down into the overlaid fabric and, with a suitable tool such as a pair of pliers, turning in the perimeter of the fabric-covered flange of the one base part to secure the other base part in nested relationship.

The foregoing procedure is awkward and slow to handle and, until one becomes experienced, the finished buckle is not always of acceptable appearance. A main objection to such buckles is that the adhesive is likely to stain the cloth in washing or cleaning.

The main objects of this invention are to provide an improved buckle-assembling device for eifecting the interlocked nested positioning of two buckle base parts with fabric tautened over the face of one base part and the perimetr-ical portion of the fabric interposed between the two base parts; to provide a two-element assembling device of this kind in one of which elements the fabric and the buckle base parts are successively depressed by the other element to effect the final interlocking nested positioning of the two base parts solely by the fabric tautened over the one base part and interposed and tucked in between the two base parts; to provide an improved two-element assembling device of this kind adapted to be contoured to accommodate buckle base parts of practically any size and shape; and to provide an improved fabric-faced buckle-assembling device of this kind of such simple structure as to make its manufacture very economical and its use extremely facile by even the most inexperienced persons.

34 and 35, a template 52 for that particular style of base parts, and sheet of instructions is marketed to be available for the individual professional or do-it-yourself workman to quickly and easily provide him with one or more buckles faced with fabric of his own choosing.

The essential concept of this invention involves a pair of elements each recessed inwardly from one face to form a cavity in one element and a telescoping rim on the other element approximately of the contours, respectively,

of a pair of centrally-open nestable buckle base parts whereby the elements may be repeatedly telescoped first, to depress into the one element one base part overlaid on a piece of fabric and, subsequently, to depress into the one element the other base part to effect its nested positioning of the base parts with the fabric tautened over the face of the one base part and the fabric perimeter interposed between the base parts to secure them in their interlocked relationship.

Two adaptations of this fabric-faced buckle-assembling device are shown, one for assembling circular style buckles and the other for assembling non-circular style 'buckles. The same reference numerals are used in describing the two adaptations except that primes supplement the numerals for FIGS. 14 to 26. Moreover, it will be understood that the following description of the structure and use of the adaptation shown in FIGS. 1-13 applies equally to the adaptation shown in FIGS. 14-26, by merely reading the numerals with primes, when referring to the latter figures.

A fabric-faced buckle-assembling device designed for use with specially-formed

buckle base parts

31 and 32, embodying the foregoing concept comprises a pair of

elements

34 and 35 respectively recessed to form a cavity 36 and a stem 37 respectively conforming to the general contour of the

buckle base parts

31 and 32 and adapted for repeated telescopic positioning to successively depress the

base parts

31 and 32 into the element 34 on an overlaid piece of fabric 33 so as to tauten the fabric over the face of the base part 31 and interpose the fabric perimeter between the

base parts

31 and 32 to secure them in interlocked relationship.

The

buckle base parts

31 and 32 as herein shown, for use with which the

elements

34 and 35 are specially designed, except for the relative shapes and dimensions, generally simulated buckle base parts that have long been available for the making of fabric-faced buckles, of either the circular or the non-circular styles. Heretofore, however, when made by hand the fabric has had to be adhered to the one base part, similar to the hereinshown part 31, and the two base parts have been nested with their concave faces opposed and secured in such nested relationship by manual bending over into the inner base part the perimetrical edges of the outer or larger base part.

As is most apparent from FIG. 7 (and FIG. 21) the outer or larger base part 31 is of C-shaped cross-section With the outer flange 38 curved inwardly toward the practically straight opposite flange 39. As these figures further show, the flange 38 is much higher than the flange 39. The inner or smaller base part 32 is of slight arcuate cross-section with an inner flat portion 41 and an outer curved portion 42. The distance between the inner and outer perimeters of the inner arcuate base part 32 is approximately the same as the distance between the opposed inner perimeters of the

flanges

38 and 39 of the outer larger base part 31. So nearly arethe aforesaid dimensions the same that the inner base part 32 generally and easily drops into nested position with the outer base part 31, with no fabric intervening. However when they become so nested the

parts

31 and 32 will not separate by merely turning them upside down and shaking them. In fact a very fine pointed instrument, suchas a pin, will have to be inserted between the nested parts and the inner part 32 angled to the outer part 31 in order to effect a separation of the parts.

Being so formed the

base parts

31 and 32 are adapted for assembly by depressing and snapping the part 32 into the part 31, with its convex face opposed to the concave face of the part 31, and with the perimetrical portion of the piece of fabric 33 interposed between the

parts

31 and 32. Thereupon these two parts are locked in such nested relationship by the interposed fabric being drawn over the edges of the

flanges

38 and 39 of the part 31 by the outer and inner perimeters of the inner part 32. (FIGS. 3 and 16.)

The two buckle forms herein shown, are intended to be representative of the two primary styles of buckle in which belt buckles have long been made. One style is circular; the other style is non-circular. Obviously, the circular style can be of almost any desired diameter. The non-circular style, in addition to being of varying dimensions may be practically of any contour. One or both of the

base parts

31 and 32 may have cross bars 43 for hinging the usual belt prong (not shown);

The fabric 33, used for facing a pair of

base parts

31 and 32, may be of almost any character and practically any thickness. The thicker the fabric the more secure will be the locking of the parts in nested relationship. However, in the use of very sheer fabric it may be necessary to use multiple layers of the fabric or an inner layer of other material.

The element 34, herein referred to as the cup or holding element, is made of an elastic substance so that it may be distorted to permit the insertion of the base part 31 overlaid on fabric 33 of varying thicknesses, and to permit the separation of the finished buckle, as will be explained presently. The element 35, herein referred to as the pusher element, is made of wood, metal, or possibly plastic.

The cup element 31 is recessed inwardly from one face to form the cavity 36 between a perimetrical rim section 46 and an opposed central section 47. The shape and contour of the cavity 36 conform substantially to the shape and contour of the base part 31. In depth, the cavity 36 is about twice the axial thickness of the base part 31. Oppositely extending

ribs

48 and 49 are formed on the opposed walls of the rim section 46 and the central sec,- tion 47. These ribs are spaced above the bottom of the cavity 36 a distance just enough more than the axial thickness of the outer base part 31 to permit the latter to be depressed into the cavity with the upper edge of the flange 38 seated under the rib 48- with the fabric 33 interposed. When this assembly device is used with

base parts

31 and 32 one of which has a cross bar 43-, the central section 47 of the cup element 34 has a slot 50 crosswise of the section 47 to a depth practically that of the cavity 36.

The pusher element 35 is recessed inwardly from one face to form the rim 37, with a rounded edge, dimensioned and contoured substantially the same as the base part 32, hence it is readily insertable into the cup cavity 36 between the

ribs

48 and 49.

To facilitate the forming of a piece of fabric 33 for proper tautening around the face of the base part 31 and interposing between the

base parts

31 and 32, a template 52 is provided. This is of the shape and size to indicate the approximate size and contour of the piece of fabric 33 most suitable for use with a particular pair of

base parts

31 and 32. Such a template 52 is formed with a series of radiating slots 53 where by the fabric may be marked for internal slitting to insure the best fitting around and between the

base parts

31 and 32.

The herein shown and described

base parts

31 and 32 and the assembling

elements

34 and 35 were conceived and constructed to make exceptionally facile fabric-facing of 'belt buckles by individual, professional or do-it-yourself workmen. To that end one or more of pairs of

interfitting base parts

31 and 32 of a particular style, a pair of assembling

elements

34 and 35 and a template 52 are marketed in -a kit in the form of a small, transparent container 54. One such a container is referred to in the trade as a plastic blister. It is secured to a display card 55 for purchase, in stores at notion counters, by mail, by the individuals who desire to make their own fabric-faced buckles.

Upon obtaining such a kit the individual effects the fabric facing of a buckle in the following manner:

(1) The template 52 is laid on the reverse side of the fabric to be used. With a suitable pencil the contour of the template 52 and the slots 53 are marked on the fabric. Thereupon the fabric is cut out on the contour line and slitted along the radial lines, ready for use.

(2) The piece of fabric 33 is placed on the cup element 34, as nearly centrally as possible, and the base part 31 is positioned centrally on the fabric, with the concave side up.

(3) The pusher element 35 is then positioned with the rim 37 seated on the base part 31 between the

flanges

38 and 39. Pressure is applied sufficient to force the base part 31 and fabric 33 down into the cavity 36 of the cup element 34 below the

ribs

48 and 49. As is most evident from FIG. 11 (FIG. 24) the pressing of the fabric-covered base part 31 below the

ribs

48 and 49, because of the friction material of the element 34, tends to tauten the fabric 33 smoothly over the face of the base part 31 and urge the fabric above the flange 38 and 39' inwardly so as to facilitate the next step.

(4) The pusher element 35 is then removed and the perimetrical portion of the fabric is pressed down into the cavity 36 and onto the base part 31.

(5) The base part 32 is then placed on the cup element 34 over the cavity 36 with the concave side up. The pusher element 35 then is positioned with the rim 37 on the base part 32. Pressure is applied to force the base part 32 down into the cavity, against the fabric over the base part 31 until the base part 3-2 snaps in between and below the

flanges

38 and 39 on the base part 31.

(6) After removing the pusher element 35, the cup element 34 is grasped, somewhat as shown in FIG. 13 (or FIG. 26), and twisted to permit a finger or thumb to be inserted under the finished buckle and remove it fiom the cup element.

As so clearly shown in FIGS. 1, 2, 12, and 13 (FIGS. 14, 15, 25 and 26) the fabric 33 is tautened over the face of the outer base part 31 and the perimetrical portion of the fabric is drawn firmly over the edges of the

flanges

48 and 49. Thereupon the

base parts

31 and 32 are locked in their nested relationship by the fabric 33 ready to have a belt prong (not shown) fastened to the nested cross bars 43 or 43'. Only by mutilating the finished buckle could the

base parts

31 and 32 be separated.

Variations and modifications in the details of structure and arrangement of the parts may be resorted to within the spirit and coverage of the appended claims.
