FLEXIBLE METALLIC STRAP Filed Dec. 1. 192a INVENTOR WW5: I

Patented June 9, 1931 UNITED STATE WILLIAM FORSTNER, OF IBVINGTON, NEW? JERSEY, ASSIGNOB TO FORSTNER CHAIN CORPORATION, OF IEVIIEGIC N, NEW JERSEY FLEXIBLE METALLIC STRAP Application filed December 1, 1928. Serial No. 323,182.

This invention relates to flexible metallic straps as used for ornamental personal wear, such as bracelets, belts, wrist watch bracelets, dress ornaments and other devices of like character.

One object of the invention is to provide a strap composed of thin wires woven to produce a fine mesh whereby lightness in weight, smoothness of touch, ventilation and desirable flexibility is attained in the underlying portion, and to arrange the same in a manner to engage a plurality of facing plates which act effectively to protect the edges of the strap.

A further feature is in the provision of such face plates in forms inexpensive to construct, that are attached in a positive manner to the strap without solder or other extraneous means, and which are readily susceptible of any desiredornamentation, as by enamelling, engraving or the like.

Another purpose is to produce an ornamental strap which may be of any width and length, and so combined with facing 5 plates as to prevent breaking or unravelling of the fine wires at the edge, and having clips at the ends which perform a similar function.

These several advantages are attained by the novel construction and combination of few and simple parts as hereinafter described and shown in the annexed drawings, forming a material )art of this disclosure,

and in which t Figure l is a plan View of an end portion of a strap made in accordance with the invention.

Figure 2 is a transverse sectional view of the same taken in a plane central of one of the facing or guard plates.

Figure 3 is a perspective view of a plate blank in detail.

Figure 4 is a similar view of the same after the first bending operation.

Figure 5 is another like view thereof, showing the plate in its completed form.

The ground work or underlying portion of the strap consists of a ribbon-like strip 10 of'fine wires, asgold, silver or plated metal, woven diagonally and preferably with selvages 11 the strip being of suitable width so that when its edge portions 12 are folded over, the curved elements 13. constitute the edges of the finished article.

The facing or guard plates 14 are blanked by ordinary die stamping processes, as shown in Figure 3, the central element be ing preferably of lesser length than the full width of the strap, and the opposed end edges of the central portion may be I of any desired configuration or plain, as indicated.

Integral with the side edges of the plate are shorter portions 15 to be bent along the lines 16 at right angles and again bent along the line 17 to present the end elements 18 in parallel with the plate 14.

The rear elements 18 are shown as being preferably longer than the front plate 14 and their edges brought into close relation, as seen best in Figure 5; it is also to be noted that the length of the elements 15 is equivalent to the distance between the selvages 11,

while the distance between the adjacent su'rfaces of the elements 14 and 18 is slightly greater than the thickness of the mesh 10.

The meshed strap having been formed as shown in Figures 1 and 2, the socket'elements, as clearly shown in Figure 5 ares moved in the manner of slides to engage the strap, the elements 15 being brought into juxtaposition and the interlocking of the parts is obviously ample to retainthe assembled parts as shown in Figure l.

Clips are provided at the ends of the strap to prevent the plates from sliding off, the same being shown as consisting of a tubular member 19 havlng opposed parallel strips 20 adapted to be pressed with sufii'cient force narrow as compared with the strap, a deposed in closely assembled relation and besirable flexibility length-Wise the strap is ing of equal width.

In testimony whereof I have hereunto af- Attention is directed to the economical fixed my signature.

5 construction of the device, including its assemblage, and also to the absence of solder, brazing or like securing means, such being wholly unnecessary.

As changes of construction could be made Within the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative or not in a limiting sense.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is

1. A strap comprising a woven wire mesh strip having inturned edges, a plurality of slides each having parts engaged under said inturned edges, said slides being formed of uniform width from sheet material and arranged in close edge relation, and a face plate integral with the slide to extend partially over the said edges.

2. A flexible strap comprising a meshed strip of wires woven diagonally and having its longitudinal edge portions folded inwardly in spaced relation to the main portion, and a plurality of metal slides shaped to form an integral socket open at both ends to slidably engage on the edge portions of said strip.

3. A flexible strap comprising a meshed strip of wires woven diagonally and having its longitudinal edge portions folded re-entrantly, a plurality of slides each having side members to engage between the adjacent edges of the strip, a facing plate on 40 said slide to extend partially over said reentrant edges, and a rear plate on the slide to extend into the folds of said edges.

4;. A flexible metallic strap comprising a woven wire strip having inturned selvaged 4 5 edges, a plurality of narrow uniformly flat plates disposed transversely of said strip to extend over its inturned edges and space therebetween in juxtaposed relation, said plates being of lesser length than the width of said strip to disclose marginal portions adjacent both inturned edges, means for slidably confining said plates thereto, and means at the ends of said strip to retain said plates thereon. 7
