INSOLE.
To all whom it may concern Be it known that T, ALBERT E. JOHNSON, a citizen of the United States, residing at Beverly, in the county of Essex and Stateof Massachusetts, have invented certain new and useful Improvements in Insoles; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I
. This invention relates to an improvement in insoles for use in the manufacture of boots and shoes, and more particularly to that type of reinforced insoles known as Econ- Omy insoles, illustrated and described in the present inventors United States Patent No. 849,245, dated AprilQ, 1907, which are used particularly in the manufacture of welt shoes. Such insoles are usually prepared for reinforcing, that is, the operation of applying the reinforcing material. to the insole, from a sole shaped blank by splitting it along its edge around the :shank and fore part to form a lip and a .feather and by cutting one face of the blank Within the edge out thereby forming a flap parallel to the lip. The flap and lip are turnedup at right an: gles to the cut face of the blank and united by cement and pressure to form a single in tegral upright rib around the Shank and forepart of the insole. A sheet of reinforcing material is now stuck roughly on the blank and the blank and sheet are then passed through a reinforcing machine. The flap and lip are united so that the Outer sur face of the flap is prevented from adhering to the sticky side of the sheet of reinforcing material. When the 'flap and lip are not united it is found that the set imparted to the flap by the turning tool is not sufficient to hold the flap from drooping toward its original position over the channel. WVhen this happens the sticky sheet of material adheres to the outer surface of the flap and thus prevents the tools of the reinforcing machine from working the reinforcing material down into the angle'between the channel and the inner surface .ofthe flap. Substantially four steps are taken in preparing for reinforcing the insole of the type described in said Letters Patent, namely; the step of edge slitting and channeling, the step oflip turning, the step of cement applying, and the step of pressure applying. The use of ce- SpecifiOation of Letters Patent. Application filedi anuary 4, 191a. Seria1 NOr6693 23.

inent adds materially. to the cost of the in sole. .Furthermore, the operation of cement applying involves theuse of special apparatus which must be carefully employed to prevent the smearing of, the insole.
The object of the present invention is to produce a novel. Economy insole which may be properly prepared for reinforcing without the use of cement, stitches,or other 11p uniting means.
With this object in view afeature oft-he present invention contemplates the manufa'cture of an insole consisting of a body portion having a flap cut-therefrom, which is permanently set by molding pressurefto preventthe exposure of its outer surface. By preventing the exposure oftheouter sur-K face of the flap the proper position of the sheet of reinforcing material on the blank, for the further operation of the reinforcing machine, is insured. l i .1
' Broadly considered the flap may be set by molding pressure into any suitable form found desirable or expedient. In order, however, to counteract the tendency of the flap to droop toward its original position over the channel the flap is rolled over throughout its length upon the'lip produced by thevedg'e slitting. This'manner'of molding the flap, along lineslongitudinal of the flap, forms an important feature of the present invention. 5
The novel insole, as illustrated, is :prepared for reinforcing by channeling and edge slitting the blank in the'usual way, then tempering the flapv and lip'thus produced, and finally setting the tempered parts by molding the flap over uponthe lip. In the accompanying drawing illustrating the improved Economy insole in the best form now' known ,to the inventor; Figure 1 is a plan of the insole, the reinforcing-material being omitted; Fig. 2 is a detail in transverse sectionshowing the molded com-. pound rib; and Fig. 3.illustrates'the detrimental effect of the reinforcing material en a gaging theouter surface ofthe flap when Said surface is exposed.
Referring nowto the drawings, a Sole fshaped. blank 1 is first passed through a channeling machine in which the edge of the blank is split along its shank and fore- ,partto produce a lip 2 and a feather 3, and
a channel is cut in one face of the blank Within the edge out toform a flap 4:. If at this step in the manufacture of the insole the flap and lip are turned up without uniting them with cement and pressure or by stitches, the flap, for reasons well known to those skilled in the art, will droop toward its original position over the channel. If not united when the sheet of reinforcing material is applied to the blank preliminary to passing the blank and sheet through a reinforcing machine, the exposed outer surface of the drooped down flap adheres to the sticky surface of the sheet as shown in Fig. 3. If the blank and sheet are then passed through the reinforcing machine it is obvious that the tools with which the machine is provided will not be able to draw the reinforcing material down into the angle between the channel and inner surface of the flap. Heretofore in order to prevent the drooping of the flap it has been necessary to unite the flap and lip by either cement and pressure or stitches.
In the illustrated embodiment of the invention the marginal portion of the blank which includes the flap and lip produced by the edge slitting and channeling operations is tempered. The tempered marginal portion of the blank is then passed through a molding machine provided with suitable rolls, or other tools, which mold the marginal portion of the blank along longitudinal lines into substantially the form illustrated in Fig. 2. As shown, the lip 2 and flap 4: are set into a single compound rib with the flap 4 molded over upon the lip 2.
By molding the fiap 4 in the manner described, its drooping tendency is counteracted, and the flap is permanently set in such position that there is no liability of the sheet of reinforcing material adhering to the outer surface of the flap.
As is well known to those skilled in the art, practical experience has shown'that, in order to permanently set the rib, something more than a mere pressure on the rib is required. It has been the practice heretofore, aft-er channeling the insole blanks, to turn up the lip, or lips, forming the rib, by hammers, rotary lip-turning tools, or other means, using pressure alone. This operation does not effectually counteract the tendency of the lip, or lips, to droop or fall back toward the face of the insole, resulting in crippled insoles as hereinbefore described. I have discovered that the permanent set,
- hereinbefore referred to, of the flap is obtained by reason of the stretching of the fibers of the leather at its upper tip-turned margin due to molding the flap outwardly throughout its length along longitudinal lines. This stretching lengthens the upturned edge of the flap relative to the length of its base, which, as will be recognized by those skilled in the art, acts to hold the flap in its rolled-over position and effectually counteract its tendency to droop toward the face of the insole.
While the present invention is particularly useful in connection with the two lipped type of Economy insole shown in my prior patent hereinbefore referred to, it will be apparent to those skilled in the art that it is equally useful in connection with the single lipped type of Economy insole which is prepared by cutting a channel in one face of the sole downwardly and outwardly toward its margin, as shown in my prior Patent No. 656,842, dated August as, 1900.
The nature and scope of the present invention having been indicated and one form v having been specifically described, what is claimed as new is 1. As an article of manufacture, a leather blank for reinforcedinsoles, having a flap which is formed by cutting downwardly and outwardly in one face of the blank and which is turned up and molded outwardly throughout its length toward the marginal edge of the blank to permanently set the flap in such position that the outer surface of the flap and the plane of the surface from which the flap is cut subtend an angle substantially less than 90 degrees.
2. As an article of manufacture a leather blank for reinforced insoles having a flap and a parallel lip cut in one face, said fiap being turned up and rolled over upon the lip with its upturned edge stretched throughout its length by a molding pressure along lines longitudinal of the flap, substantially as described.
3. As an article of manufacture, a leather blank for reinforced insoles, having a flap and a parallel lip cut in one face, said lip being turned up and permanently set in up-turned position by molding pressure,
and said fiap being turned up against said lip with the fibers of the leather at its upper margin stretched to lengthen its upturned edge relative to the length of its base by being molded throughout its length along lines longitudinal of the flap to permanently setit in upturned position and prevent drooping, substantially as described.
