` This invention relates to insoles 'for use in the manufacture ofshoes of the types 1n which an upper is lasted over upon an insole and secured theretoin lasted position and partioularlyto insoles provided with pro-` jections to which the upper may be secured in lasted position, for example, by staples, an outsolebeingapplied to the shoe in contact with the overlasted upper. Insoles" of this type 'are disclosed in United States Lettera Patent Nd 1,744,759, granted Jan,` 28,

v1930, `on my prior application of which this,

application is a division. A

yObjects ottheinvention are-toV providean `improved insole to which the upper maybe iattavched by metallic fastening-s without anyVV liability of the fastenings appearing onthe` vinner tace of the insole, to provide an` insole the outer surface ofwhioh, after attachment of the upper, will be smooth and substantially unbroken, aswell as to provide an insole which will be convenientto use and cheap to As herein illustrated, the invention provides aninsole comprising two layers of material which are coexpensive with the last bottom, the outer. layerwhaving cuts extending through it and providingiaps "which v may be readily raised so that a clinehing tool may be placed beneath the' raised portions to clinch' against the flower face Aof the outer layer afastening driven through theuppeiV and the outer layer` In the illustrated form of the invention,

the "outer layeris slit -longitudinally of the sides otlthe naps by a clinchingtool placed beneath them, It the upper is progressively lasted, the clinching tool may be moved along the slit in position to clinch successive fastenings driven through the upper and the nap. After lasting,the flaps are laid down .smoothly in their original position against the inner layer of the insole. In order that the portions of the flaps near the ends of the u shoe may be raised more freely, transverse the ends of theinsole softhat the ends of the] shoe may be lasted in 'the same Way as the sides.` j f Other featuresfot the inventionV will aption when readin connection with the accompanying drawing and will be pointed out in theclalms. i

pear more fully from the following descrip- AAlthough the invention has been'V illusi tratedas embodied in a shoe" in which `the outsole is `attached by through-and-through stitching, `it is to be understod that, in its broader aspects, the inventionis not limited` to this manner of attaching the outsole. j

4In` the drawing, 1 "Fig.` l is aperspectiveview of aninsole showing-a form of the invention; and i ing an insoleof the form'shown in Fig; `1."

Insoles` embodying `the present invention are preferably of sheet-material, such as buclrram, canvas or split leather, the illustrated material beingfrictioned canvas-of such weight that two thicknesses of it will provide" the desired strength and tiexibility for the insole. Thus the insole-illustrated in Fig.. l consists of two adhesivelyconnected pieces of sole-shaped frictioned canvas 4g and` one overlying the other.- An advantage oi employing"frictioned canvas is thatthe` two layers` comprising the insole may be caused 'to adhere simply by being pressed together.

It' should be understod, however,` that for either or both ot the layers 4 and 6, material other than trictioned canvas may be substituted, and other means ofsecuring the insole layers together maybe employed. Conveni i A' F1g. `2 1s aftransverse section of alshoe haviently, although not necessarily, the pieces 4 and 6 are died out or otherwise cut to insole shape before one is placed on the other. The layer 4, which constitutes the outer layer of the insole, has a longitudinal slit 8 and transverse cuts at the breast line 10 and at the tip line 12, preferably made prior to the 'fastening of the two layers together and forming flaps 14 and 16. Preferably the layers 4 and 6 are attached to each other only along the marginal portions between the tip line and the breast line, that is outside of the dotted lines shown at 18 in 1, and such attachment is preferably made bythe use of cement, although, ot course, stitching along the lines 18 may be employed it desired. The width of the margin 24 of the insole between the attached edge of the iiap and the edge of the insole is sufficient to permit an outsole to be applied to the overlasted portion of an upper as shown in Fig. 2 and secured to the shoe in any desired manner, for example, by stitches passing through the outsole or a portion thereof, through the upper and through the margin 24 oi the insole.

In use, the insole is placed upon the bottom of a last with the face having the flaps 14 and 16 outermost, the two layers of the insole being coeXtensive with the last bottom. An upper 28 is placed upon the last `and lasted over the margin 18 of the insole, each successive portion of the upper being secured preferably by a staple 26 driven through the upper and one oi the flaps, and clinched on the under side of the iiap. The iiaps may be raised prior to the lasting operation and if not are readily raised in the stapling operation by the anvil or channel guide of the stapling machine. The anvil of a staple lasting machine is passed through the slit 8 beneath the part 14 or the part 16, according to which side of the shoe isbeing lasted, and in the operation ot the machine the upper is drawn over the insole and a staple driven through the upper and one oit' the portions 14, 16 of the insole, the staple being clinched by the anvil on the under tace of the outer layer. rlhe machine employed may be ot the type disclosed an application Serial No. 138.800 filed Sept.28,1926by George Goddu. In the use of this machine successive portions of the upper are tensioned by a gripper, and, while control of the upper is maintained by a staple nozzle, a staple is inserted through a tensioned portion ot the upper and one of the iaps 14, 16. the staple being clinched by a channel guide or anvil disposed against the under side of the iap. After the lasting has been effected by securing tensioned portions thereoie to each of the flaps at the two sides ot the shoe, the flaps are pressed bach into the recesses from which they were cut, leaving the bottom of the insole perfectly flat and substantially unbroken. Filling material may be dispensed with, or

at most, only enough filler inserted to compensate i'or the thickness of the margin of the overlasted upper. At the toe and heel the upper may be lasted, for example, on a bed type oLt' lasting machine, and tacks driven through the upper and completely through the insole, their points beingr clinched by the metal plates with which the toe and heel ends of the last are provided. An outsole is then applied to the shoe in any usual manner, as illustrated, the last is removed, and the outsole, upper and insole secured together by through-and-through stitches 22 passing through the margin 18 of the insole outside of the line oi the staples 26.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An insole for shoes comprising a plurality of layers attached together at their mar- ;.ins, one of the layers being slit longitudinally ot the sole to permit the insertion of a tool beneath said layer for clinching fastenings driven through the upper and the layer.

2. An insole for shoes comprising a plurality of layers attached together at their margins, the inner layer being intact and the outer layer being slit longitudinally of the sole to permit the insertion of a tool beneath said layer for clinching fastenings to hold the upper to the outer face of said layer.

3. An insole comprising a plurality ot' similar layers secured together at their margins, the outer layer being cut through longitudinally of the insole to permit the insertion ot a clinching tool for clinohing tastenings driven through the upper and the outer layer adjacent to the margin of the insole.

4. An insole for shoes comprising a plurality of layers attached together at their margins, one of the layers being slit centrally longitudinally of the sole to permit the insertion of a tool for clinching the fastenings by which the upper is held to the insole.

5. An insole for shoes comprising` two layers, the outer layer being cut longitudinally trom the breast line to the tip line and having transverse cuts at the tip line and the breast line whereby the outer layer may be raised to permit the insertion of a tool for clinching tastenings by which the lasted upper is held to the insole.

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