INSOLE.

Application filed May 19, 1922. Serial No. 562,097.

To all whom it may concern:

Be it known that I, l/VARREN B. ll iirrn, a citizen of the United States, and resident 01 North Abington, in the county 01 Plymouth and State of Massachusetts, have invent-ed an Improvement in Insoles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing lilre parts.

My present invention is an improved insole for use in the manufacture of boots and shoes, preferably used in the novel process illustrated in my prior and copending application Ser. No. 511,590, tiled October 31st,

1921, the present case being a divisional in part of said prior application.

In my development of improvements in the art of making boots and shoes, wherein I last the shoe and thereafter remove the lasting tacks or their equivalent, .i. e., metallic lasting devices, withdrawing same from the insideoit the shoe after it is otherwise completed. I have necessarily devised a new insole construction to permit me to carry out the same. In my present application I have elected to claim broadly, the preferred forms of insole, several modifications being capable of use.

as herein shown in the attached drawings, I utilize an insole which may receive and carry the metallic lasting devices, i. e., the equivalents oi the ordinary lasting tacks so far as the holding off the upper and insole is concerned, during the processes of manufacture, and thereupon the insole permits either a complete witl'idrawal of the insole and removal. simultaneously withdrawing and removing these lasting devices; or a ten'iporary partial ren'roval of the insole from the inside oi' the shoe to permit the removal therefrom of the lasting devices and then a replacement ot the insole in the shoe; or a removal of a part oil. the insole carrying the tacks. In addition to these forms of insole is the it rther modification wherein the lasting devices or tar-its are carried on a separate removable strip, the latter being capable of ripping out from the insoe of the shoe, thus removing the tacks while leaving the insole undisturbed.

This latter form is not herein illustrated.

Referring to the drawings, showing preferred embodiments of the invention,

Fig. 1 is a fragmentary view, partly in cross-sectlon;

Fig. 2 is an edge view of my insole; and

lsig. 3 is a crossrsectioual view, transversely oi. a shoe, illustrating certain of the modifications.

Referring to the (musings. and as e1:- plained more fully in my said process ap plication, one of the tumlan'lcntal points in my improvement in boot and ioe manufacture is a shoe construction and insole therei'or which will permit the shoe to be lasted in a substantially usual manner, but with the lasting tacks or devices first lined in the insole and the upper drawn over and caught on the points. The shoe is then completed in the usual McKay or through and through method of stitching, whereupon the last he mg removed, the Mcliiay stitching set, the metallic lasting tacks or devices are withdrawn from the inside of the shoe. In the drawings the insole 1 is of siiiitable size and contour for the insole in llllclllay shoe construction, in which the same is to be used. Preferably also I may have the marginal part recessed or cut in as indicated from the lull width of the heel i arl [along each side to the toe part 3,.in case it is desire-d to have the line oil? lricl iay stitchi set outside the edge of the insole from one to heel, for greater tieoility is frequently now customary. mlhe upper (3 is shown in tr n'ientary and cross-sectional position in Fig. 1, and at the right in Fig. 3 is shown in one method of stitching, and at the left in still another, uniting the sho with the outsole 8.

In one form of my insole I prepare the same by applying a suitable number 01" tacks or metallic lasting devices 10, these being set through the insole along the marginal edge with the points projecting to receive the marginal edge of the upper 6 after the same is lasted and caught on the points substantially as indicated at 11 and 12, Fig. 3, the upper being held thereby. It will be understood that the heads ot the tacks rest against the last during this operation. The upper is pulled over and lasted by the usual pulling over and hand method lasting niachines if desired, or by hand, and the up per caught on the projecting points of the lasting devices 10 and thus held. Thereupon the operator may cut the insole on the line 15 before the outsole 8 is applied. If desired also, the insole may be first severed on the line 15 and then re-cemented or united and the same may be similarly out on the lines 16 and 17 In the latter instance the shank portion between the lines 16 and 17, Fig. 1, could be lasted by other than metallic devices, and only the forepart of the insole 1 removed or partially removed from the shoe, for the subsequent withdrawing therefrom of: the lasting devices.

In case the insole is of full width, as is usual, and as illustrated at the right of Fig. 3, the McKay stitching 5 engages the same and the lasting tacks 10 may be removed by cutting or severing or originally forming a separate strip 18, this being inside the line of stitching and therefore capable of r moval without disturbing the McKay stitching of the permanent shoe fastening means. In case the insole l is cut away at the sides from 2 to 3 as described and as illustrated in Fig. 1, then the stitching 5 will not engage the marginal edge of the insole, but will hold the upper and outsole as illustrated at the left, Fig. 3, thus leaving the tacks l0 and the entire insole 1 tree to be lifted up and partially withdrawn from the torepart and sh. nk ot the shoe, so that the operator can easily remove the lasting tacks and replace the insole. This latter form is preferable.

Ineither event, I use metallic lasting tacks to hold the upper and insole united during the processes of mautacturing the shoe and then ater the McKay stitching is applied and while the last is withdrawn, I lift out, remove or partially remove the insole or the part ot the insole carrying the lasting de- \-'ices--whieh are readily extracted from the upper t without injury-the stitching 5 having previously been set therethrough, knock or push out the same, push out the lasting tacks. and thus torni a tackless and flexible McKay shoe.

The shoe construction as illustrated at the right of Fig. 3, results in a substantially McKay shoe structure, while the shoe construction as illustrated at the left of Fig. 3, is, in effect, a turn shoe structure, Without the necessity of turning the shoe. In both forms the tacks are removed and no metallic fastenings left in the shoe, and yet the advantages of McKay shoe structure, i. e., strength, simplicity, economy and increased comfort, are present.

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

1. An insole for boots and shoes, having its forward portion separably attached to the shank portion thereof, whereby the intermediate portion may be removed from the shoe after the outsole and shoe upper have been attached to the insole.

2. An insole for use in the manufacture of shoes, having a plurality of lasting tacks fitted therethrough and adapted to be assembled on a last with the heads of the tacks in contact with the last bottom, said lasting tacks being removable after completion of the shoe.

3. An insole-like member for use in the manufacture of boots and shoes, having a plurality of lasting tacks applied therethrough in predetermined position, and said plurality of tacks being removable by a single operation after the completion of the shoe.

4. An insole for boots and shoes, having a removable portion, extending from the toe portion rearwardly to the shank, said portion being temporarily removable from the shoe after the upper and outsole have been attached, and lasting tacks can be withdrawn from the torepart and shank of the removable portion and such portion be replaced in the shoe.

In testimony whereof, I have signed my name to this specification.

WARREN B. WHITE.
