Specification of Letters Patent.

Patented May 17, 1910.

Application filed September 29, 1909. Serial No. 520,114.

To all whom it may concern:

Be it known that I, GEORGE T. MoLnon, a citizen of the United States, residing at Dedham, in the count-y of Norfolk and State of Massachusetts, have invented an Improvement in Machines for Cutting and Slitting Insole-Reinforcing Strips, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to cutting and slitting devices for insole linings.

As well known by those skilled in the art, it is usual to reinforce insoles of boots and shoes by means of a piece of fabric or canvas which may be cemented thereto and its edge portions tucked into the channel formed by the usual upturned channel lip. As pointed out in-an application filed April 15, 1909, Serial No. i90,160, the dimensions of the fabric or canvas reinforce have been such as to practically cover. the entire surface of the insole, although the essential function of the fabric is to reinforce that portion of the insole designed to receive the fastening means which unite the insole to other portions of the shoe structure, any projecting edge portion of the fabric being cut away. Said application also described an invention, and claimed it broadly, whereby the waste incident to theold manner of reinforcing insoles was avoided, the characteristics of which invention were embodied in a reinforcing strip made narrower than the width of the insole and slitted so that the portions adjacent to or on opposite sides of the slit might be separated or spread so as to reinforce that part of the insole primarily intended to be strengthened. The present inline 3-3, Fig. 2; Fig. 4 is a front detail view of the collector for assembling a plural number of strips in proper relative position for presentation to the cutting table; and Fig. 5 is a plan view of a fabric or canvas reinforcing strip after it has been produced by the present invention.

The fabric or canvas from which the reinforcing pieces are to be cut is or may be preferably of uniform or standard width and less than that of the insoles which are to be reinforced. Long strips of such material are first coated on one side with an adhesive or cement and after drying sufficiently are wound on suitable reels or spools.

A series of reels or spools 2, Fig. 1, each containing a roll of the reinforcing fabric or canvas 3, are suitably supported in a frame 1, said frame, in the present form of the invention, being indicated as angular in shape, though, of course, any suitable frame containing any suitable number of rolls of the fabric or canvas strip may be employed.

Disposed in suitable relation to the sup porting frame 1. is a collection frame 4, Fig. 1, provided with a series of guide rolls 5 over or between which the several strips of fabric or canvas pass, as indicated in Fig. l, to a collector 6. The collector 6 is indicated in detail in Fig. 4 and preferably comprises a standard 7 rising from a base piece 8 which may be secured by a lug 9 and suitable bolt connections passing therethrough to the collection frame 4:.

Projecting from the standard 7 is a stud shaft 10 at the top thereof, on which is mounted a guide roller 11, said shaft 10 being preferably connected to the standard 7 by means of a thumb screw 12, whereby it may be readily detached from the standard 7 for introduction of the strips of fabric or canvas, as indicated in Fig. 1, the outer end of the stud shaft 10 being preferably provided with a pin 13 or other suitable means for retaining the guide roller 11 thereon. Secured to the standard 7 below the stud shaft 10 is another stud shaft 14: which, like the shaft 10, has mounted thereon a guide roller 15, the construction being such that the several plies of fabric or canvas passing over the guide rolls 5 of the collection frame may be passed between the guide rolls 11 and 15 and thus collected in proper position for presentation to the cutting table.

Projecting laterally fromv the standard 7 below the guide roller 15 is a pin 16 to the outer end portion of which is secured the hub 17 having the upwardly extending guide arms 18 which, as indicated in Fig. 1, preferably embrace the outer portions of the guide rolls 11 and 15. By adjusting the hub 17 on: its supporting stud 16, the arms 18 and hub 17 may properly guide the assembled strips of fabric or canvas into proper assembled relation for presentation to the cutting table, as will be readily understood.

The cutting table, one form of which is indicated in Fig. 2, comprises a base portion 19' which may be suitably supported ona bench or other sustaining means and is preferably provided with a trough or guide way 20 formed by longitudinally extending side members 21, Fig. 2.

Spanning the guide trough 20 is a retainer Fig; 2', preferably secured by screws 23 or otherwise to the side members 21, said retainer having a forwardly projecting prong or finger 24 adapted to engage with the top of the assembled strips of fabric or canvas which are passed beneath to thereby maintain them in proper place and prevent the ends of the several pieces of fabric or strips retreating from the trough 20 after the operator has severed the reinforcing sole portions, such as- S, Fig. 5.

At the end of the trough 20 opposite the retainer 22 is a stop 25 against which the forward ends of the assembled strips bear when they are drawn forward into cutting position, a cutaway portion 26 being provided near the stop 25, so that the hand of the operator may arrange the ends of the assembled strips in proper relation with the stop 25'. Hinged or pivota-lly connected to suitable supporting arms 27 at 28, Figs. 2 and 3-, is a clamp or cover plate 29, which, when in operative position, as indicated in Figs. 2 and 3, is adapted to overlie and rest upon: the assembled strips of canvas or fabric beneath.

In the present embodiment of the invention, the clamp or cover plate 29has its rear or severing portion 30 preferably somewhat wider than the main body of the clamp or cover plate, said rear or severing portion 30 being provided with transverse slits 31 extending the full width of the trough or guideway 20, the construction being such that when the clamp or cover plate is in position as indicated in Figs. 2 and 3, a knife may be passed down any one of the slits 31 and sever appropriate lengths of reinforcing sole pieces from the assembled strips.

Extending longitudinally of the clamp or cover plate 29 to the left of the rear or severing portion 30 thereof is a slot 32 also adapted to have passed ther'ethrough a suit able cutter or knife to form the slit 33' inthe forepart portion of the reinforcing strip when applied to the shoe sole, as indicated in Fig. 5. Likewise extending longitudinally of the rear or severing portion 30 of the clamp or cover plate is another longitudinal slot 34 permitting the passage of a knife or cutter for the formation of a slit 35 in the reinforcing strips near the heel portion of a shoe sole, as indicated in Fig. 5. Likewise extending longitudinally in the trough or guideway 20 of the table is a slot 36 corresponding to the slots 32 and 34 to accommodate the point of the cutter or knife.

In order to determine the length of the reinforcing strip corresponding to diiferent sizes of shoe sol'cs, consideration must be taken of the fact that since the reinforcing strip S is to be separated at its slitted portions more or less, as set forth in application Serial No. 490,160 hereinbcfore mentioned, therefore for wide soles greater length of canvas reinforcing strip must be provided than for the more narrow soles and likewise the length of the longitudinal slits 33 and 35 will vary. In order to readily meet this condition, the clamp or cover plate 29 is provided with suitable marks on its rear or severing portion indicating the particular location of cut corresponding to a wide and to a narrow solc, as

indicated in Fig. 2'. Mounted onthe rear or severing portion and secured thereto by asuitable set screw 37 is a gage edge 38 having a stem 39 by which said gage edge may be adjusted to the particular number indicating the length of reinforcing strip either in case of wide or narrow soles. Similarly, the longitudinal slot 32 is provided with a series of size marks, one for wide and the other for narrow shoe soles, and a gage 40 secured to the 01311111101 cover plate 29 by a suitable clamp screw 41 may be moved to proper position in accordance withthe character of solo being treated.

hen the cover or clamp plate 25) is turned down upon the assembled strips of fabric or canvas, it is desirable that it be held in this position while the operator passes his knife transversely and then l'ongitudinall-y of the assembled strips. To this end there is pivoted on suitable supporting brackets 42 a clamping member 43 having a hand. grip portion 44 and bearing in portions 45, which latter are adapted to contact with and press upon the clamp or cover plate 29, as will be clearly apparent from Figs. 2 and 3, the construction being. such that the operator may with one hand pull up ard upon the hand grip 44 of the clamp and with the other hand may pass his knife through the appropriate slots for slitting and severing the as sembled strips.
