chines of the extruding type are in common use Patented July 27, 1943 l 'This invention relates to shoe-bottoni-coating machines and'is herein illustrated as embodied in a machine for coating one face of a flange adjacent to the-bottom oi the shoe andextending around a portion of the'periphery thereof.

Certain shoes of the stitchdown type are manufactured by forming an outwardly turned'ilan'ge adjacent to the inseam aroundthe periphery of thebottom of the shoe, orat least that portion of the bottom which is forward of the heel breast 1-ine,-and by securing to this flange by adhesive a strip of beveled welting. In order to make such shoes light and flexible, the above-mentioned flange is both narrowand'thin and is tapered to ward its edge. Itmay; for example, be only one 7 I eighth of an inch in width and as little as one sixteenth of an inch thick :at its'hase'; One coating of the'ce'ment which is to attach the welting' is i is brought into engagement withthe 'feedwheel. This-feed wheel serves also tofguide'the'shoe as it'istumedto carry the successive portion-sot applied to the outer face ofthis flange and, when 1 this'i-s done by turning the shoe to present the successive portionsfof' the flange toa coating 1 member'such as an extrudingnozzle, consider; able care is required in handling the work because of the tendency of the'fiange to jump over the nozzlaand thisdificulty is accentuated when overlapping seams such as'are usually found between the 'vamp and the quarter are encountered.

To provide a coating machine facilitating this which have a feed roll engaging the side or bottom of the shoe and which are provided with depending nozzles for the application of cement to either the marginal portion of the bottom or to some nearby area. In such machines an inverted shoe is held'up by the operator against the nozzle and is pressed laterally to contact with the feed wheel and it is turned by the operator as he presents successive portions of the periph cry to the nozzle. ihe illustrated machine in accordance with the features of the invention is of the general type of those just described andis arranged to facilitate the presentation-of the i work. It will be understood that the above-mentioned flange extends outwardly from the side of the shoe at a sharp angle thereto, thus form I ing a crease. Accordingly, the nozzle of my im-' proved machin tapered or pointed so-that it v tion of the'arrowIII onFig. 1;

as shown, embodiedzin a machine of the type illustrated in Letters Patent of the United State s No. 2,100,341, granted November 30, 1937, on the application of W. L. MacKenzie. As in that machine, a feed wheel N) is mounted'upon a swingingcarrier l2 which is pivoted about an, axis at a substantial distance below, the feed wheel be-- tween sides of. a frame of which one side is shown in Fig. 1. This swinging movement is parallel to the plane of the paper, in the direction i in the patent, a nozzle 24. is supported upon an will enter this crease, and is provided with a latto mount'the nozzle'for swinging movement so as to accommodate the changing relation of the crease, and the flange adjacent thereto, to the of the double-pointed arrow l5 and is limited in one direction by the engagement of a flange 18" on the carrier l2 with a stop 26 mounted on the V I frame. In thisicarrier 12 are mounted driving means 22 arrangedto rotate the; feed wheel to carry the portion thereoflwhich contacts the bottom B of a shoe S, away fromthe observer.

In a man ner 'generallysimilar, to that shown outwardly extending rod 26 whichis clamped in an arm 23 pivoted to the frame at a point some distance to the right of the nozzle. Vertical adjustment to permit the nozzle to bebrought into v the proper relation fto the feed wheel is accom- V plished loy a threadedstop screw 30 on the arm which engages a flange 32 onithe frame and a spring (not shown) urges the arm 28 counteronnectionfwitlr v clockwise toward-the position shown. On this ported upon the upper sides of these arms and" is held in position thereon by a clamp" pivoted on a rod 43 and engaging the upper surface of the plate. The workengaging 'portion' of the nozzle comprises a tapered plate 44 which has a passage 46 leading to an outlet opening 48 and presented progressively to the nozzle, the flange F on the shoe will drag across the inclined outlet slot and the cement will be pulled upwardly in the groove 48 and will more perfectly be distributed across the outer face 92 of this flange F. A forwardly-extending rounded lip 94 on the tip of the nozzle rides easily in the crease which is adjacent to theflange F. I s V In the use of the machine, as successive portions of the outer surface 92 'of the flange F are presented to the nozzle th operator will press this plate is attached by dowel pins 50 and as screw 52 to the side of a triangular portion ;54.

This portion has spaced, upwardly-extending arms Stand 58 (Fig. 3) through whichis passed a pivot pin 69 extending also through a'hub'portion 62 which is integral with and hangs below theplate 40. The tapered portion 44 of thenozzle is urged in a counterclockwise direction, as

V viewed in Figs. 1 and 2, by a spring 64 coiled" around ahead 66 of the pivot pin and whichat one .end engages the arm 58 and at its other end. abuts a 'pin ,68 ,(Figgz), This movement, whenqnojworlr ispresent, islimited by a stop screw 10 threaded in a boss Hertendin laterally iromthe forked member 54. r

Thedelivei'y ofcementunder pressure to the nozzle is effected by means of a, hollow neck 14 having. a flange 16 by means of which it is screwattached to the upperside of the plate 46. This neck has a passage 18 which communicates with a recess 80 Fig-.2) in the upper side of the plate and thencebyjan inclined passage 82 to a recess 84 (Fig. 3). on the inside of a detachable plate 86' which ,is held -by screws upon the' hub 62.

From this recess 84, the cement is delivered to the passage in'the taperedportion through a flexible capillary tube SS-clamped on the hub r 62 by means of the above-describedplateiii and ,communicating with the recess 8 4; therein. The lower end of the tube,;proteoted bya cover plate I 89,;slidably engages a passage 90 in the plate 44-which is in direct ,communicationwith the passage 46 therein.- It will be noted from Fig. 5 e that the outlet slot 48 extends diagonally across the bottom surface of the" nozzle ate 44 in a direction extending upwardly and forwardly from the passage 46.; Asaresult, when the work is the bottom B of the shoe against the feed wheel land will raise the shoe to bring the flange F into contact with the nozzle. Moving the shoe awayfrom the observer in Fig. 1, the pressure exerted by the operator will be in a general upward direction, resolving itself into two components, one extending inwardly toward the feed wheel and the other extending diagonally toward the nozzle, with the result that the part of the upward pressure which is exerted'toward the nozzle is substantially in line with the pivot Wand, therefore, has practically no efifect in swaying the nozzle toward and away from the machine. The nozzle beingheld by the spring 64 against the flange F will ride easily along this flange, regardless of any overlapping seams that may be encountered, and this riding of the nozzle upon the work is facilitated by the rearwardly extending lip 94. Such an arrangement permits the spring 64 to be relatively light, and enables the operator to present the very narrow and flexible flange F without difficulty.-
