INCORPORATED, or" ROCHESTER, NEW YORK, A CORPORATION on NEW YORK.

INsOLE.

To all whom it concern Be it known that I, SIDNEY a citizen of the United States, and a resident of Rochester, New-York (whose postofiic'e addre'ss'is No.11 Elwood Building,

Rochester, New York), have invented an Improvement in' Insoles, of which the following description, in connection with the 1s a SPGClfiCHlHOIl,

accompanying drawings, like letters on the drawings representing like parts.

My present invention is an improved and novel formof insole for use in the manufacture of boots and shoes."

It is an object of my present invention to simplify and improve the construction and processes of manufacturing boots and shoes and to provide a: novel construction which will enable a fleiribl'e'shoe to 'bemade. To this end, I have" devised a novel type of insole capable" of use" in the manufacture of a McKay type of shoe substantially equivalent in flexibility, attractiveness and desirability to a turn shoe, together with the strength, wearing qualities and simplicity of construction of a McKay shoe and preferably utilizing certain ofthe machines ordinarily employed in the manufacture of welt shoes, particularly in the pulling-over and lasting. 7

The present application is directed to cover the insole and in my companion application, Serial No. 326,567, filed September 26, 1919, I have shown, described, and claimed the process of making my new shoe, employing the insole of the present invention; and in my companion and copendin application, Serial No. 332,222, filed October 21, 1919, I have illustrated and claimed the completed shoe as an article of manufacture, which shoe embodies the novel insole herein disclosed and said shoe being preferably made by the novel process of said application.

My present insole is prepared from the usual stock type of leather welt insole stock, such stock being capable of the method of channelling which I employ. This channelling is upon opposite surfaces, i. e., one channel on the grain side of the blank and the other channel on the flesh side. These channels are preferably staggered slightly, the channel on the grain side being preferably split in from the edge of the insole entirely around the shank and flap excepting the G. WrLsoN,"

usual inside appearance,

toe portion and the heel portion. Asthe grain side of the" leather is' intended to be that next the foot of the wearer and there fore on'th e inside of the sho'e, I form this channel so as to cover the McKay stitching with which the shoe employing my present type of insole'is preferably made. on the opposite or flesh side of the insole, i. e.,' the under surface or that next the outsole, I form-a channel by cutting from the inner ormedial portion of the insole surface toward the outer edge, as these channels are subsequently layed or? cemented down wardly, receiving the-stitching through and through, the full strength of the insole, excepting theslight stitching-covering channel on the grain side, is thus obtained for stitching-holding in a completed sh'oel I believe that this prepared insole, as well as the double channeling and with the channelscut as indicated, viz, the grain side split in from the marginal I the" flesh side channel cut from inwardly edgewardly," are distinct novelties in' the art of shoe manufacture and of preparing an insole and I therefore wish to claim'these features broadly.

Referring to the drawings illustrating a preferred embodiment Fig. 1 is a view of the grain side or top surface of my novel insole;

Fig. 2 is a view of the flesh side showing the channel as cut therein;

Fig. 3 is a cross sectional view onthe line 33 of Fig. 1; and

Fig. 4 is a diagrammatic cross sectional edge and I view showing the insole in position on a last.

As shown in the drawings, I utilize a suitable leather insole blank of any desired contour and for any size or style of shoe and on the top or grain surface, I cut a channel flap 2 around the forepart and shank on each side, leaving the toe 3 and heel part 4 uncut. This channel is preferably formed by splitting the edge portion, as clearly indi-- cated in Fig. 3, leaving the feather 5 formed of preferably the greater thickness of the insole than that formed on the flap 2. This channel thus formed is to cover, conceal, and protect the McKay stitching, giving the comfort and wear of a welt shoe.

On the reverse or flesh side of the insole blank, I cut the channel '6 around the shank and entirely around the forepart and toe, the same being shown in dotted lines in Fig. 2 and illustrated in Fig. 3. This channel is cut from the center of the insole outwardly toward the edge, leaving the channel lip 7. l Vith the insole thus prepared, I am enabled to apply the insole l on a last 10, assemble the upper materials 12, i. e., upper and lasting, having had the flap 2 either turned back as shown in Figs. 1 and 4, before the same is applied to the last, or turned back after the last is removedand before the McKay stitching is put in. With the insole thus channeled and positioned as shown in Fig. l, the upper materials 12 are lasted, preferably by the pulling-over and lasting machines utilized in welt manufacture or in exactly the same manner as turn shoe manufacture, whereupon the edge and lasted upper is secured to the lip 7. This can be stitched like a turn shoe or can be attached, the staple holding the lasted upper and lip 7 as indicated at 16, Fig. 4. Thereupon the outsole may be appliedthe last 10 removed and the McKay stitching 15 sewed, as usual. The forepart 2 is then cemented and turned down and the shoe completed.

My prepared type of shoe to be made substantially as a turn shoe and even pulled over and lasted by welt shoe machinery, entirely without the use of permanent tacks, thus making a tackless McKay shoe--excepting at the exstapled or otherwise insole thus enables a McKay trelne toe and heel. Furthermore the construction produces the flexibility of a turn shoe with the simplicity of processes of Mo- Kay shoe manufacture and the advantages of this invention will be readily appreciated by those skilled in the art.

My present invention is further described and defined in the form of claims as follows:

1. An insole for boots and shoes adapted for shoe construction employing through and through fastenings, having a channel flap formed on the grain side and a channel lip on the flesh side, each capable of being laid substantially flush with their respective sides, said channels having their inmost line of cut disalined.

2. An insole of the kind described having a channel flap formed on the marginal portion of the grain side out inwardly from the marginal edge, and a second channel lip around the forepart and shank formed on the opposite surface of the insole, said lip being out from the center line of the insole outwardly toward the marginal edge, and both flap and lip being adapted to be laid substantially flush with their respective sides in the completed shoe.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

SIDNEY C. WILSON.
