T0 all 'whom t may concern:

Be it known that We, LoRING Q. WHITE,- HENRY'l ODoNNELL, citizens of theUnited States, and residents of Brockton, county'of Plymouth, State of Massachusetts, have invented an Improvement in Innersoles, of which the following description, in connection vrith the accompanying drawing, is a specification, like characters on the drawing representingT like body of the. inner sole from' the-outer e` ness less than the l body of ythe innerwsole, and 1n order to provide an inner 'solemade This invention relates to inner soles such as are used in the manufacture of welt shoes and has for its object to provide a. satisfactory inner sole which can be made from leather or other material that has not suflicient thickness or strength to permit the inseam-stitch-receiving lip Vto be formed by channeling the body of the inner sole-from the margin or edge thereof and yet leave a marginal edge exterior to the lip having sufficient strength and stiffness to meetthe requirements enacted of the edge of an insole in the manufacture o'f a Welt shoe.

One ivell-known type of inner sole that is commonly used in the manufacture of Welt shoes* is the so-called gemined inner sole which is made from a piece of leather or similar material that is channeled at its marginal edgeto form a lip to which the' Welt and upper may be sewed, the lip and underside of the inner sole being covered with a layer of canvas. In an inner sole for Welt shoes one necessary feature is a lip of suitable strength to permit the Welt and upper to be sewed thereto, and another' necesedgeof requisite strength ahd. a'lip requisite size and strength from very thin turers to use in' the manufacture of innei` been unable to use for this purpose.

invention, We have illustrated in the drawings selected embodiment thereof `which will noiv be described after which the novel features Will be pointed out in the .appended claim;

Inthe drawings, 4sole is shown at l and it may lbe made of any suitable material. This body portion is channeled, as at 2, thereby to the channel 2 being situated at a suitable distance in from the edge or periphery 4 ofthe body 1, so that the portion 5 of the body between the channel and the exterior edge 41 is of the full thickness ofthe body. In thev manufacture of Welt shoes it is necessarythat the marginal edge of the inner sole should have a certain amount of rigidity and strength, it is possible to use any material, no matter how thin, so long as the fullthickness of the material will ymarginal edgel Where the body 1 is made edge outside of the lip which has sufficient strength and thickness soethat it Will not give when it is acting as a guiding edge dur# ing the rough-rounding, roodyear stitching, and other operations in the manufacture of the shoe, for if said marginal edge is lacking in strength or rigidity it is liable to give or yield under the pressure it receives from the guiding element of the machineduring the; above operations, and if this occurs the operations will not be properly performed.
