CORPORATION OF JERSEY iuAcH'mE Eon AnnnE'rnon or 'or E 'riNG UPON snoEs' Application filed August 16,1929. Serial na asaaes.

This invention relates to machines for and methods of operating uponshoes, and is herein shown and described as embodied in a machine for treating'a portion of the upper of a lasted shoe to prepare the shoe for the reception of a sole. v

According'to one method of shoe manufacture the sole is: secured to-the upper of the lasted shoe by cement, and it is an object of the present'inve'ntion to providean improved machine for preparing the portion of the upper to which the sole is to be attached in sucha manner that the .cement will adhere strongly to itand, consequently, a secure and permanent attachment of'the sole will be obtained. The treatment for which the illu'strated machine is designed consists in removmg the surface finish from the overlaste'd portion of the upper and roughenin g, byabrasion, scratching or cutting, the said overlasted portion to producea suitable cement receiving surface thereon.

This 1 operation has heretofore been performedby 'a'tool mounted upon a rotating shaft,the lasted shoe being held in the hands "of the operator and beingpr'esented manual- -ly tothe tool; The extent and location of the area tooled and the depth of the tooling has been determined entirely by the operators judgment, and a high degree of skill, and care was required to produce good, uniform work.

' An important feature of the present invention consists in the provision, in a machine forperforming the above described upper tooling operation, of mechanical means for feeding the work past thetool, preferably at a substantially'uniform rate, thereby greatly facilitating the production of uniformly satisfactory results and reducing the amount of skill and caredemanded of the operator.

In the illustrated machine, which is adapt ed to'operate upon a shoe lasted, for example,

' by the method described in the prior. application of GeorgeGoddu' Serial No. 386,097, filed Aug. 15, 1929, there is provided'feed mechanism which operates upon the work by engagement with the insole of the lasted shoe. As shown, the machine operates upon the lasted 'shoeprior to the trimming operation by which the insole lip or rib andthe upstanding margin of the upper is removed, the feed mechanismbeing arranged to engage the lip of the insole. Theffeed mechanism may comprise oscillating fingers engagingthe inner side of theinsole lip and causing the work to move continuously in the directionin which said lip extends While the upper treating tool is operating upon the portion of the upper overlying and parallel to-the insole outside of the lip. l

Another feature ofthe invention resides in the provision of work guiding means odoperating with the insole lipor rib and engaging the upstanding portion o f'the upper. in the anglefformed by the overlasted portion ofthe .upper'and the; upstanding margin of 7 fthesame', which lies against the outerside' of the insole lipor" rib. In the illustrated embodiment of the invention the work guiding means comprises a frusto conical member adapted to enter the angle above referred to and not onlyfguide the work but alsoconstitute an abutment to resist the thrustfoff'the work feeding'fingersias they anama-teens insole li to secure operative engag ment therewith. a 1

Q In thisconnection invention is also to be recognizedin a frusto conical roughening tool, in: combination with a work guide, operating in the angleformed by the insole lip or rib and the shoe bottom, permitting side and overlastedportions thereof and making it' easyfto confinethe actionof the tool to exactly the overlasted portion of the upper,

whichisthe portion that "it isdesired to'pre- Inasmuch as the portion of the upper which power. .7

is to be tooled comprises a band of overlasted upper material of a width which does not vary greatly and has the same contour as the insole lip or rib, the said lip may be utilized with advantage in presenting the work progressively to the tool, and, in one of its aspects, the invention includes that improvement in methods of making shoes having lipped or ribbed insoles whichcomprises toolstood and appreciated from reading the following detailed description of a machine embodying the invention and a manner of practicing the method, in connection with the accompanying drawings in which Fig. 1 is a side elevation of the operating mechanism of the machine, with parts broken out to reveal the internal structure;

Fig. 2 is a plan view, taken upon the line IIII of Fig. 1, showing the action of the Work feeding mechanism; Figs. 3 and 4 are fragmentary views showing the roughening tool, the feed fingers and the upper presser in operative relation to the work in the forepart and shank portions of a shoe, respectively; and r Fig. 5 is a perspective view of a shoe which has been operated upon.

Referring now to Fig. 1, indicates a suitable base or column upon which is secured a housing 12 supporting the operating mechanism. Journaled in the housing 12 is a shaft 14 which is continuously driven, as by an electric motor or any other suitable source of Gear teeth 16, formed upon the shaft 14, constitute a pinion which meshes with a spur gear 18 secured to a shaft 20 also journaled in the housing 12 and connected by .a positive clutch 22 to'a shaft 24 to the outer end of which is secured a miter gear 26 meshing with a similar miter gear 28 secured to a vertical eccentric shaft 30, the purpose of which will be described in detail hereinafter.

A bevel gear 32, fast upon the outer end of the shaft 14, meshes with and drives a bevel gear 34 which is secured to the upper end of an inclined rotating shaft 86. Removably secured to the lower end of the inclined shaft 36, by means of a screw 38 (see Fig. 3) is an upper treating or roughening tool 40 which, as illustrated, is ofthe greatertvpe, but may be of any kind suitable for tooling the shoe upper in a manner to produce the desired surface thereon. The illustrated tool is designed to remove the surface finish from the .upperleather and to roughen the leather slightly to prepare it for the application of cement.

Loosely mounted at the back of the tool 40 is a frusto-conical disk-like work guiding member or gage 42 which is free to rotate about the axis of the shaft 36 but is restrained from bodily movement in all directions.

While the tool 40 is power driven and rotates continuously, the guide member 42 is adapted to enter and engage in the angle formed by the portion 44 of the'upperof a shoe 46 on a last 48 and the upstanding portion 50 of said upper. 52 indicates the insole of the shoe and 54 designates the insole lip or rib to which the upstanding portion 50 of the upper is lasted and secured and against which it rests. The portion 44 of the upper, which is drawn over the marginal portion 56 of the insole, is, for the purpose of identification, designated in the present specification and the appended claims as the overlasted upper or the overlasted portion of the upper.

It will be seen that the progressive presentation of'the surface of the ov'erlasted upper to the tool 40 is facilitated by the guiding action of the disk-like member 42 running in the angle formed by the upper at the outside of the insole lip or rib and co-operating with the lip or rib. For the purpose of further facilitating this progressive presentation of the work to the tool there are provided feed fingers 58, 60 having pointed ends adapted to penetrate the inner side of the insole lip or rib 54 and feed the shoe progressively relatively to the tool 40, in the direction of the lip. v p

The feed fingers 58, 60'are carried respectively by oscillatory slides 62, 64 guided in a casing 66 supported by a bushing 68 surrounding the shaft 24 and by a rod 70 which is slidable horizontally ina stationary bracket 72, to which red the casing 56 is secured by set screws 74. The bushing 68 is parallel to the rod 70 and is mounted to slide in a stationary bracket 76 formed upon the housing 12, the casing 66 being secured to the said bushing by a set screw 7 8 and the clutch 22 being constructed to permit endwise movement of the shaft 24 relatively to the shaft 20 while maintaining the two shafts inoperative, driving engagement. 7

A very strong spring 80, one end of which is secured to the bracket 7 2 and the other end of which is secured to the rod 70, tends to move the rod and consequently the work feeding mechanism toward theleft, as viewed in Fig. l, causing the points of the feed fingers 58, 60 to engage the insole lip. For the purpose of retracting the feed fingers to permit the insertion of the insole lip and theupstanding portion 50 of the upper betweenthe feed fingers and the guide disk 42, there is provided a bell crank lever, one. arm 82 of which engagesa collar 84 secured to the rod 70 and the other arm 85 of which is connected tracting the feed by a link 86 to a rock shaft 88 constructed to bined reciprocating and oscillating move ment the effect of which is to cause the points of the feed fingers 58, 60 to move in approximately elliptical paths, as shown by the broken line 102. These paths are substantially identical but the eccentrics 98, 100 are ofiset angularly relatively to each other so that the feed fingers engage the-work alternately and feed it substantially continuously.-

An overhanging bra-cket 104 mounted upon the bearings for the shaft 36 affords asupport for a guide 106 in which is mounted a slide 108 carrying apresser 110 adapted to engage and press thelasted upper ofthe-shoe closely against the side of the last adjacent to the corner defined by the intersection of the side and bottom faces ofthe last, as illustrated in Figs. 3 and 4. The purpose of thisis to form; the shoe upper to a definite angle or corner at the intersection of the side and overlasted portion thereof, thus makingite'asy to confine the action of thetool 40- to exactly the overlasted portion 44 of the upper,.which is the only partupon which it is desired that the tool shall act. Theslide 108 is connected to a bell crank lever112 acted upon by a stilf spring 114 which, however, is weaker than the spring SO-sothat the work-willbe positioned against the work guiding member 42. The spring 114 urges the presser 110 yieldingly toward the tool 40 and presses the lasted upper closely against the side of the last. In operation the treadle is depressed; refingers 58, and permit ting thelasted shoe to be presented to the machine with the'insole lip, and the upstanding marginal portion of the upper which is lasted thereto, positioned in the space between the feed fingers and the-work guiding member 42. In thus presenting the shoe to themachine the side portionzof the upper, adjacent to'the shoe bottomiis pressed firmly against the presser 110, 'the yielding mounting of which permits the work to be positioned against the guide 42, while maintaining considerable pressure upon the up per and drawing it tightly over the edge of the insole forming a well defined corneror edge to determine the exact boundary of the area upon which the roughening tool 40 can operate. I

r The treadle now being released, the feed fingers are advanced by the spring 80 until their points enter intowork feeding engagement with the inner side. of the :insole li-p or rib. Withthe work thus-positioned; the rotating tool .40 engages andoperates upon the definitely determined surface area of the g:

overlasted portion 44 of the. upper, the feed fingers 58,160 utilizing the insole lip to feed 'thework progressively in the direction in which said. lipextends and the work guiding member 42 also utilizing thelip5-through the upstanding portion ofv the upper which is lasted thereto,- as a guide to determine accurately the direction of the feeding movement.

Since the guide member 42 isbodily immovable and resists the thrust of-thefeed' fingers normally to the insole lip, both the,

progression of the work pastithe tool 40 and the determination of the path which: it moves are effected, mechanically at; a -sub-' stantially uniform rate, thereby facilitating the even uniform action'of the-tool '40 upon the overlasted upper of the shoe.

.-The feed mechanism acts rapidlyto ad Vance the work past the treating tool from one end to the other of the area to be-tooled, whereupon the treadle is again depressed permitting the work to be removed from the machine. .The1tooled s'urface.'ofz the overlasted portion of the upperv appears as shown at 44in Fig. 5 and is in the best possible condition; for the reception of soleattaching;
