11 Claims.

This invention relates to improvements in machines for use in applying pressure to shoe bottoms and is illustrated herein as embodied in an apparatus adapted more particularly for use in cement attaching soles to shoes.

thereafter secured to the shoe bottom by nails after which the heel or the heel base is attached to the heel seat portion of the sole by additional nails. In attaching the heel end of the sole to theshoe by nails the edge portion of the sole is forced tightly against the heel portion of the shoe bottom and, since the nails are clinched on the inside of the shoe, this edge portion is maintained permanently in such position. The heel attaching nails likewise cause the edge of the heel or heel base to be forced into close fitting relation with the edge of the sole and they hold these edges permanently in that position so that, after the sole has dried out, no openings or spaces will appear between these edges such as might result if no nails were used owing to differences in the firmness of the leather materials at the heel seat portion of the shoe which cause the leather to react more in some places than in others and tend to return to its original uncompressed condition when the heel attachingpressure is relieved.

When, however, the heel portion of the sole is to be attached to the shoe bottom by cement alone and when, in addition, as is the case with" many shoes manufactured today, the heel or heel base is also to be attached to the heel seat portion of the sole by cement alone, a problem arises with respect to securing and maintaining a close fitting relation'between the edges of these parts 40 at the heel end of the shoe because, in such cases,

no nails will be present to maintain said edges permanentiy in the close fitting contact they had while under heel-attaching pressure.

Accordingly, unless some means is provided for overcoming these difficulties, shoes having both the heel seat portions of their outsoles and their heels or heel bases attached by cement alone to produce a so-called nailless heel seat are apt to have spaces or openings appear between the sole edge and the shoe bottom at the heel portion of the shoe, or between the sole edge and the edge of'the heel or heel base.

Objects of the present invention are to provide improved apparatus for use in applying pressure to soles and shoes including the entire heel portions thereof, and to provide improved means for operating on the heel seat portions of soles during the application of pressure thereto in order to eliminate the difi'iculties above referred to in constructions in which both the heel seat portion of the sole and the heel or heel base are to be attached respectively to the shoe and the sole by cement alone.

To the attainment of these objects and in accordance with one of its features, the invention provides an improved pad box structure constructed and arranged to apply pressure to the entire areas of a sole and a shoe bottom and simultaneously to mold or conform the heel portion of the sole to the shape of the attaching face of a heel or heel base. As illustrated herein, the pad box has a yieldable pad provided with a sole and shoe receiving surface which is deformableunder pressure and is arranged to extend over the entire bottom area of the largest shoe tobe operated upon. A smooth surface for engaging the sole is provided by a continuous flexible blanket or cover, preferably of resilient material, which can be deformed with the yieldable surface of the pad during the pressure applying operation.

The improved means referred to for operating on the heel portion of the sole comprises, as herein illustrated, a rigid plate interposed between the yieldable pad and the flexible cover and constructed and arranged to mold or conform the heel seat portion of the sole to the shape of the attaching face of a heel or heel base while sole attaching pressure is being applied to the sole and shoe, thereby producing a smooth, even compressed edge on the heel seat portion of the sole which could not be obtained by pressure from a yieldable pad alone owing to hard and soft spots in the material of the sole. As illustrated, the rigid plate has a floating contact with the operating surface of the pad so that it is free to tip or bemoved heightwise of the shoe with said surface as the pad and cover are deformed under the pressure applied to the shoe and sole. The operating surface of the plate is concave and corresponds in shape to the attaching face of a heel or heel base so that, as the pressure isapplied, the heelseat portion of the sole will be molded or conformed to the shape of said attaching face. This insures that the edge of the sole will be compressed evenly and without high and low places which would cause open spaces'between the sole edge and shoe or between the sole edge and the edge of the heel or heel base after the heel attaching pressure was relieved in cases where cement alone was used to attach the sole to the shoe bottom and. to attach the heel or heel base to the sole.

In accordance with another feature of the invention, the conforming plate is adjustable longitudinally of the pad box, thereby permitting the plate to be readily positioned for operating on soles of different lengths. As illustrated herein, the adjustment of the plate is effected by manually operated means whereby the plate may be moved predetermined distances lengthwise of the pad without interfering with its freely movable floating relation to the pad or the pad cover. Moreover, the longitudinal adjustment may be accomplished, in accordance with the present invention, without displacing the flexible pad cover overlapping the plate or interfering with the operation of the pad or mechanisms associated therewith.

Still another feature of the invention comprises an improved arrangement for insuring that the heel end of the sole will always be properly positioned on the pad relatively to the shoe. Since the flexible cover overlaps the concave surface of the rigid heel conforming plate, the cover may, under continual use, gradually conform to the concave shape of said surface and thus render it difiicult for heel positioning gages which are arranged to operate in a fixed or predetermined plane to engage the edge face of a sole located in this concave or cupped surface. This difficulty is overcome in the present construction by causing the operative ends of positioning gages for locating the heel end of the sole relatively to the shoe to rest by their own weight or gravity on the surface of the pad cover and to ride or slide on this surface during their operative movement into engagement with the sole. In this way there is no opportunity for the gages to ride over the top of a sole located in a concave depression at the heel end of the pad and consequently danger of the gages failing to engage and position the sole is eliminated.

With the above and other objects and features in view, the invention will now be described in connection with the accompanying drawings and will thereafter be pointed out in the claims.

The invention is illustrated herein as embodied in a pad box for use in a cement sole attaching machine of the type disclosed in Letters Patent of the United States No. 2,047,185, granted July 14, 1936, on an application filed in the name of Milton H. Ballard et al., this pad box being modified in the manner disclosed in Letters Patent of the United States No. 2,005,755, granted June 25, 1935, on an application filed in the name of Francis J. Better, to adapt it more particularly for operating on large size shoes, such as mens shoes. As disclosed in the Ballard et al. patent, the pad box is secured by screws 12 to a radially projecting portion l3 of a supporting shelf or table which forms a portion of a rotary turret on the cement sole attaching machine. The pad box comprises a fixed casting M for supporting the rear portion of a yieldable pad l6 and a movable casting [8 arranged to swing about a center 20 for supporting the forward portion of the pad and for positioning this portion at a. proper angle for the shape of the shoe being operated upon. As herein illustrated, the yieldable pad I6 comprises a hollow bladder, preferably of rubber, filled with fluid such as Water, and it extends to the rear or right-hand end of the fixed casting 14 of the pad box, as shown in Fig. 8. The movable casting l8 carries sole and shoe positioning gages, indicated generally by the numeral 22 and being of substantially the same construction as those disclosed in United States Letters Patent No. 2,063,041, granted December 8, 1936, on an application filed in the name of Lloyd G. Knowles.

The rear or right-hand end of the pad box as viewed in Fig. 1, is provided at its opposite sides with vertical guideways 24 in which is adjustably mounted a slide member 26 the upper end of which projects horizontally to form a supporting plate or table 28 upon which is mounted gage mechanism for relatively locating the heel ends of a sole and shoe on the pad, the plate 28 also supporting mechanism forming a part of the present invention for conforming the heel portion of a sole to the shape of the attaching face of a heel or heel base during the' application of pressure to the sole and shoe. The slide 26 is adjusted in the guideways 24 and is main tained in adjusted position by a screw 30 (Figs. 3 and 8) threaded into a horizontally projecting lug 32 formed on the lower end of the slide, the screw being secured by a lock nut 34 in a fixed bracket 36 fastened by screws 38 to the casting [4 of the pad box. In adjusting the slide 26 heightwise of the pad box the lock nut 34 is loosened and the screw 30 is turned until the proper heightwise position of the slide is attained, after which the lock nut is made fast again against the fixed bracket 36. The heightwise position of the slide 26 is determined, in a manner to be hereinafter explained, in accordance with the amount that the flexible pad I6 is distorted under the sole attaching pressure. It will be seen from the above that the slide 26 and the mechanism carried thereby are fixed against movement heightwise of the shoe during the operation of the machine but that they are capable of adjustment heightwise of the shoe.

The horizontal projection 28 on the slide 26 carries sole and shoe positioning mechanism with which a pad box of the present type is provided for relatively positioning the heel ends of a sole and shoe on the pad, this mechanism comprising, as fully disclosed in the, Better patent referred to, a plurality of substantially horizontal members 40 (Figs. 1, 3 and 8) which carry a pair of

transverse slides

42, 44 adapted to operate, respectively, by means of inclined slot and roll arrangements 46 (Fig. 6) and 41 (Fig. 4) a pair of pivoted shoe positioning gages 48 and a pair of pivoted sole positioning gages, indicated generally by the numeral 50. The gages of each pair are interconnected respectively by gear segments 52, 53 for equal and opposite swinging movement toward and away from a shoe and sole on the pad. The transverse slide 44, which operates the sole positioning gages 50, is caused to move inwardly of the machine away from the operator by a tension spring 54 (Fig. 8) when a roll 60 (Fig. 6) is removed from engagement with the end of the slide by treadle operated mechanism including a bell crank lever 62 operating the roll 60 through a link 64, this lever 62 being also arranged to operate the forepart gage mechanism 22 through a second link 66 which connects it to said mechanism.

The transverse slide 42 for operating the shoe heel gages 48 is actuated through the movement of a swinging frame member 68 (Figs. 1 and 3) which is arranged to be moved manually from, a rearwardly inclined, inoperative position into a substantially vertical, operative position by a handle if The slide 42 is connected by a rod I2 to a pivoted arm M (Fig. 3) on the swinging frame 68 so that forward movement of the swinging frame causes the slide 42 to be moved forwardly toward the operator and, by reason of the roll and inclined slot arrangement previously referred to, to move the inter-connected shoe gages 48 into engagement with the shoe resting on the sole.

As shown in Figs. 1 and 8, the several gage supporting members 49 are arranged for pivotal movement about a horizontal pin I6 so that the operative ends of the gages may yield upwardly, if necessary, during the pressure app-lying operation, the normal position of the gages, however, being determined by a stop screw I8 (Fig. 1) and a compression spring which constantly urges the lower member of the group 40 against the stop screw. The gage mechanism may also be adjusted longitudinally of the pad box by means of a slot 82 (Figs. 2 and 8) formed in the supporting plate 28, the mechanism being secured in adjusted position, however, during the operation of the machine by a thumb screw 84 passing through the slot 82 and threaded into a spacing block 85 and a slide 88 mounted thereon, these last-mentioned members supporting the members 48 and gage mechanisms carried thereby and locating the gage mechanisms in a proper position heightwise of the pad box for operating on the heel ends of mens shoes.

The supporting plate 28 of the slide 26 has secured to its left-hand portion, as viewed in Figs. 1 and 8, a plate 98 which is shaped like the heel end of a large shoe in plan view and-has an upstanding wall 94 adjacent to its edge which forms a heel shaped container for supporting a yieldable heel engaging pad 86, preferably formed of solid but relatively resilient material such as rubber. The pad 96 is shaped at its left-hand end (Fig. 8) to join with the adjacent wall of the fluid filled pad I6 which underlies the forepart and shank portions of the shoe and sole and, as shown in Figs. 8 and 10, the pad 96 extends above the wall 94 so that its exposed surface coincides substantially with the yieldable surface of the pad I6 when both pads are under pressure, this heightwise position of the pad 96 being determined by the positionof theslide 25 g which, as previously pointed out, is controlled by the adjusting screw 36. Overlying the top or sole and shoe supporting surfaces of the adjoining pads I6 and 96 is a flexible blanket or cover 98, preferably formed of resilient material such as rubber and forming a continuous unbroken surface for receiving the sole which is to be attached to the shoe bottom.

Extending downwardly from each side of the plate 99 is an ear I00 and in these ears is r0- tatably mounted. a transverse shaft I02 having secured to its opposite ends by pins IE4 (Figs. 1 and it!) a pair of upwardly extending arms Hi8. The upper ends of the arms IE6 have pivotally connected thereto, by pins 598, a pair of substantially horizontal links Hi3 which, at their other ends are pivotally connected by pins I I2 to a substantially heel shaped plate I I4 which is fiat on its lower surface (Fig. 8) and is cut away or cupped at its upper or operating surface IIB (as shown in Figs. 5, 8 and 10) to correspond substantially in shape to the concave surface of the attaching face of a heel or a heel base of the proper size and shape for the shoe on the pad. The plate H4 is preferably composed of metal such for example, as bronze and is rigid and non-yielding under pressure. The arrangement of the arms I 06 and links III] is such that the rigid heel conforming plate is superposed on the pads I6 and 96 and can ride or float on the upper surfaces of the pads, as best illustrated in Fig. 8, so that when these surfaces are deformed under the sole attaching pressure applied by the machine, the rigid plate will be depressed heightwise of the shoe but will be returned to its initial position by the pads when the pressure on the shoe is relieved. The rigid plate H4, as shown in Figs. 5 and 8, is arranged to be interposed between the yielding surfaces of the pads I6 and 96 and the continuous flexible cover 98 and may be located in such position lengthwise of the pad box that it will operate to conform or mold the heel seat portion of the sole to the shape of the attaching face of a heel while the sole and shoe are being pressed together during the pressure applying operation, the sole at this time being in suficient temper to permit its conformation under pressure. Since the flexible cover 98 rests on the concave surface of the conforming plate II4 it may and usually does under continual use partake of or conform to the shape of this surface so that it ultimately becomes concave in shape even when no pressure is being applied to the sole and shoe.

It is desirable that the rigid sole conforming plate H4 be adjustable longitudinally of the pad toposition it for operating on soles of different lengths. To this end the arm I 96 at the front side of the pad, as viewed in Fig. l, is provided with a forwardly projecting stud IIS (Figs. 1 and 7) rotatable in the arm and having an ear I23 (Fig. 10) in which is mounted a pin I22. Pivoted to this pin is a substantially horizontal link I24 pivotally connected at its other end by a pin 52% to an ear I28 rotatably mounted on an arm I39, which, in turn, is pivoted by a vertical pin I3! to a forwardly projecting plate I32 secured by screws I36 to the under side of the slide block 86. As shown in Figs. 3 and 10, the vertical ,pin I3I extends through the plate 532 and is held therein by a cotter pin, and a compression spring I 36 is mounted between a head on the pin l3I and the arm I30 to hold the latter normally against the plate I32. Forwardly of the projection I28 the arm I30 carries a downwardly extending indexing pin I38 (Fig. 10) which is arranged to enter any one of a series of holes I 49 formed in the outer portion of the plate I32 on a radius struck from the center I3I and thus to adjust the plate I I4 into proper positions longitudinally of the pad for operating on soles of different lengths. The arm I30 forms a handle whereby the upstanding arms I96 may be swung as a unit with their shaft N32 to adjust the heel conforming plate II4 forwardly and rearwardly of the pad box between the cover 98 and the upper surfaces of the adjoining pads I6 and 28. The pin l38 may be withdrawn from one of the holes I46 and inserted in another by moving the handle I30 manually against the compression spring 536.

The conforming plate II4 is provided at the opposite sides of its left-hand portion, as viewed in Figs. 1 and 10, with upwardly projecting lugs I42 having upper portions extending inwardly toward each other. These projections overlie the upper surface of the pad cover 98 just forwardly of, or toward the toe end of the pad relatively to, a pair of rectangular projections I44 (Figs. 6 and 9) formed on the opposite edge faces of the cover 98. The cover is thus maintained in substantial contact with the operating surface IIE of the sole conforming plate I M by the overhanging lugs 42 and it is also prevented by the projections I44 from buckling or becoming loose longitudinally of the pad during the application of sole attaching pressure to successive soles and shoes.

As indicated above, the flexible cover 98 may tend under continual use to conform or shape itself to the concave operating surface of the rigid plate H4 so that the upper surface of the cover upon which thesole rests is likewise concave. The sole gages 50 and shoe gages 48 are carried by mechanism which, while it is capable of adjustment angularly with respect to the pad by reason of the pivot '56, spring 85 and adjusting screw I8 (Fig. l), is not, as disclosed in the Better patent mentioned above, normally arranged to permit the sole gages to rest by gravity on the pad or to ride on the surface thereof during their operative movement toward or away from the opposite edge faces of the sole. Accordingly, in order to insure that the sole gages 50 will rest by gravity on the exposed surface of the flexible cover 98 and will ride along this surface during their operative movement, the sole gages have been constructed in the manner illustrated in Fig. 9 to permit the operating portions of the gages to ride on the surface of the pad cover 98 and thus to be always in a position to engage the opposite edge faces of the sole. As shown in Fig. 9, the interconnected segmental portions 53 of the sole gages rest on, and are actuated by the trans verse slide 44. These portions 53 are provided with laterally extending arms 548 which are bifurcated to form ears at their left-hand ends and have pivotally secured thereto, by pins I55, extensions or arms I52, the left-hand ends of which form the sole heel gages proper. This pivoted or hinged construction of each gage arm I48, I52 permits the operative ends of the sole gages torest by gravity on the surface of the pad cover 98 and thus causes them to ride over this surface during their operative movement toward and away from the opposite edge faces of the sole. Accordingly, the gages will always engage and position the sole irrespective of its thickness and irrespective of the shape of the surface upon which the sole rests.

The cement sole attaching machine in which the pad box of the present invention is embodied is provided with abutments I54, i56 (Fig. 1) for engaging, respectively, the forepart of the shoe and the last in the shoe. These abutments are operated, as disclosed in the Ballard et al. patent, by substantially .horizontal pressure applying levers I58 (Figs. 1 and 3) to apply the sole attaching pressure to the sole and shoe.

Although the operation of the mechanism embodying the present invention will be apparent from the foregoing description, a brief summary will be given for the purpose of clearness. The operator places a sole A on the pad cover 98 and depresses a gage operating treadle on the cement sole attaching machine to cause the combined forepart sole and shoe gages 22 and the heel end sole gages I52 to move into engagement with the opposite edge faces of the sole, the forepart gages merely finding the sole on the pad and becoming locked in operative position while the equally and oppositely movable heel sole gages move the heel end of the sole bodily relatively to the pad to locate it thereon. As stated above, the sole gages I52 ride on the concave or cupped surface of the pad cover 98 during their sole positioning movement. After positioning the heel end of the sole on the pad, the sole gages I52 become locked against movement away from the sole by reason of the roll and inclined slot arrangement 47 on the slide 44, as fully described in the Better patent referred to above. Since the sole A is thus located on the pad and is positively positioned longitudinally thereof, the operator can see where the heel seat portion of the sole is located with respect to the sole conforming plate H4. Consequently, he can, if necessary, adjust this plate lengthwise of the pad by the handle I36 until the plate is in a position to operate only upon the heel seat portion of a sole of the size mounted on the pad. During this adjustment the sole conforming plate slides readily between the pads IIS and 96 and the pad cover 98, and the pad cover is prevented from being displaced relatively to the sole conforming plate.

by the overhanging abutments I42.

The operator places a shoe B, assembled on a last C, on the sole, the forepart of the shoe being positioned relatively to the sole by the locked forepart gages 22. It will be understood, of course, that the inner or attaching surface of the sole, including its heel end, and the marginal portions of the entire shoe bottom have been previously treated with a suitable cement such, for example, as pyroxylin, and that this cement has been activated and is otherwise in condition to attach the sole permanently to the shoe bottom when pressure is applied to the sole and shoe.

The operator next swings the swinging frame member 68 forwardly into a substantially vertical position, as shown in Fig. 3, by the handle I0, thereby locating the shoe engaging abutments I54, I56 in position to engage respectively the forepart of the shoe and the top of the heel portion of the last 0. He now depresses a pressure applying treadle on the machine to actuate the fluid pressure operated pressure applying mechanism thereon and to cause the levers I58 to move the abutments I54, I56 into engagement with the shoe and last and thereby to apply the sole attaching pressure. This action sinks the sole and shoe into the pad cover 98 and into the yieldable surfaces of the pads I6 and 96, thereby deforming these surfaces and depressing them heightwise of the shoe. Since the shoe conforming plate H4 is connected by the pivoted links H!) to the adjusting arms I06, the plate is, of course, free to move heightwise of the shoe as the pad cover 98 and the surfaces of the pads are deformed and depressed. Consequently, when the full pressure has been applied to the shoe and sole, the rigid conforming plate H4 molds or conforms the heel seat portion of the sole A to the shape of the attaching face of the heel which is to be attached to the shoe, the molding taking place while the heel seat portion of the sole is being permanently attached to the shoe bottom by cement. At the same time, the portions of the sole A forwardly of the heel portion are being cement attached to the shoe bottom under the pressure exerted against the sole by the forepart and shank portions of the pad. When the pres sure on the shoe and sole is relieved as the pad is about to return to the operating station, in the manner described in the Ballard et al. patent, the sole A including its heel seat portion will be permanently attached'to the shoe bottom and this heel seat portion will also be molded or conformed by the rigid plate I I4 so that it is substantially complemental to theattaching face of a heel or a heel base.

It will be seen from the foregoing that the present invention not only provides for the permanent attachment of the heel portion of a sole to a shoe bottom in such a manner that the edge portion of the sole is located in close fitting relation with the shoe bottom, but it also provides for simultaneously molding or conforming the heel seat portion of the sole to the shape of the attaching face of a heel or heel base so that the latter may be applied to the sole by cement alone without having openings or spaces appear between the edges of the sole and the heel or heel base caused by an irregular or wavy edge on the heel portion of the sole. Since the sole conforming mechanism is adjustable for various sizes of shoes without disturbing either the pads or the sole and shoe positioning mechanism, the-apparatus is easy to operate. The convenience with which the heel conforming plate may be adjusted lengthwise of the pad and the accuracy with which this adjustment may be effected owing to the fact that the operator can see the longitudinal position of the sole on the pad before he makes the adjustment, all tend to render the use of the apparatus quick, economical and eflicient.
