SHOE-TIP.

SPECIFICATION formng part of Letters Patent No. 507,793, dated October 31, 1893.

Application filed August 11I 1892. Serial No. 442,807. (No model.)

Shoe tips of leather are commonly made byA skiving the edge of the piece of leather then folding the skived edge on itself and cementing it down prior to forming or molding the tip in the machine which is employed for this purpose. The .upwardly projecting portion of the tip which protects the upper is subjected to the severest wear, and the upper edge of this upwardly projecting portion is apt to be the first part of the tip to wear through. Since this upper edge is formed by folding upon itself the skived edge of the original piece of leather from which the tip is made when substantially one-half of the total thickness of the tip is worn away it is worn through to the fold and leaves this edge in a ragged and poor condition, giving the shoe a shabby appearance.

My invention has for its object to provide a tip which shall obviate these objections, and it consists in a tip made from a piece of ,material, the edge of which ,has been skived in the peculiar man ner hereinafter set forth and folded upon itself so that substantially the full thickness of the material is preserved at the Wearing points, all as hereinafter described. i

In the accompanying drawings to which reference will be made in the following description, Figure 1 is a perspective of thetoe of a shoe showing a tip in position. Fig. 2 is a sectional view of a piece of leather used in making a tip, showing the skiving commonly employed and indicating by dotted lines the` method of folding the skived edge. Fig. 3is a similar view of a piece of leather such as is employed in making a tip embodying my invention. Fig. 4 is a sectional view of a fiuished tip of common construction such as is made from a piece of leather skived and folded, as shown Fig. 2. Fig. 5 is a similar view of a tip embodying my improvement.

As the method of manufacturing tips is well known and as tips embodying my invention differ from those heretofore made only in the construction of the edge of the upwardly projecting portion I will confine my description to the construction of this edge. At A, Fig. 1, I have shown a shoe tip of common form, applied to a shoe. The upwardly projecting portion which protects the upper is subjected to the greatest wear. The upper edge of this portion is commonly made by skivingthe leather, as shown at lc, Fig. 2, on the flesh side and folding the skived portion on itself as shown by the dotted lines in said figure. In this way only the blacked side of the Ieather shows at the edge and a finished edge is produced. It will be noted however that the thickness'of the leather in front of theline of fold tis considerably lessened by the skiving operation, and when this leather is worn through to the line of fold the value and appearance of the shoe isimpaired. To avoid this difficulty I skive the edge of the piece of leather from which the tip is made, as shown Fig. 3, that is, instead of a straight bevel as shown Fig. 2 a shoulder b, is formed on the' flesh side of the stock and the stock is beveled or skived from this shoulder to a feather edge, as shown at f. This leaves the stock on and behind the shoulder andA forms a thin skived edge in front of. the shoulder which serves to fold over and give the desired finish. By the old method of preparing the stock the skivededge which was folded over was unnecessarily thick for the purpose of obtaining a finish while the line of fold was carried forward and the stock in front of the line of fold was comparatively thin and less able to resist wear. When the edge of a piece of leather, skived in the improved manner herein set forth, is folded to form the edge of the tip the parts assume the position shown Fig. 5, and the upwardly projecting portion of the tip is preserved in its original thickness or substantially so, from its base near the sole to the top or upper edge thereof.

The full body substantially,of the stock used lfor the up wardlyprojecting portion of the tip remains in front of the line of fold, and not only is the stock dilferently located with reference to the line of fold by reason of the difference in cutting or skiving the edge of the IOO piece of Vleather but slightly morefstock is thrown into the upwardly projecting portion of the tip which enables the tip to be finished under greater pressure thus increasing the solidity and density of the stock in this portion of the finished article and rendering itl more durable. It will also be noted that thlere is an increase in the total thickness of the stock from the base to the top of the upwardly projecting portion of atip embodying my invention, and this is important as the wear is greatest toward the (top,l

A shoe tip made in accordance with myin- Vention is much easier to manufacture in that i the skived edge is easily and accurately folded over the shoulder b, the`V shoulder 4servin g as a :guide from which to fold; the materiah however, the material isskived from a shoul-` der as heretofore described this Yirregularity disappears and agregular anduniform foldis easily obtained which is important.

What I cl'aim is-- 1. A colnpressed, molded shoe tip consisting of a strip of material which is formed With a beveled shoulder b on its rear side, and with a flap of reduced thickness extending from said shoulder to one edge of the strip, said fiap being turned back on the main thickness of the strip on the line of fold which is determined by the said shoulder, and the tip being formed and molded to shape by pressure, substantially as and for the purposes set forth.` r w W 2. The process of manufacturing shoe tips which consists in first forming a beveled shoulder on one side of a strip of material and skiving the said material from the said shoglder to afeather'edge on one edgefof the strip,` then foldin g the ``fiap of reduced 'thick- 'ness th'usformed oerthefshoulder o`n""a line which is determined the saidshoulder, and finally molding the tip to sh'ape under pressure, substantiallyasset forth, r r In testimony whereof Iatfix my'signatui'e in presence oftwo witnesses. 1 w
