8 Claims.
This invention relates to machines for use in the manufacture of shoes and is illustrated herein with reference to shoes having outsoles which extend only a short distance rearwardly of the heel breast lines of the shoes, the present application l being a division of my copending application Serial No. 228,469, filed September 6, 1938, and covering Methods for use in the manufacture of shoes.
Outsoles of the type referred to are frequently attached to the shoes by pyroxylin cement in a y sole attaching press, the cement being first applied to the outsole and overlasted shoe upper and allowed to dry. Just before the sole attaching pressure is applied the cement is activated by a solvent to put it in condition for sticking the sole to the shoe bottom. Since outsoles of the present type do not overlap the entire heel seat portion ofthe shoe bottom it is especially difcult, particularly in presses having no sole and shoe positioning mechanism, to position the sole and shoe relatively to each other in the press after the solvent has been applied.
An object of the present invention is to provide Aan improved machine for use in relatively positioning a shoe and a short outsole and establishing such positions so that they may be readily reestablished prior to the attachment of the outsole to the shoe.
To the accomplishment of this object the invention provides in accordance with one feature an improved machine having means for supporting a shoe with an outsole resting thereon and provided with mechanism for relatively positioning thesole and shoe. As herein illustrated, a fastening member is located between the outsole and shoe bottom and is attached to the heel seat portion of the shoe. Further means is provided on the machine for forcing the fastening member into the outsole and shoe while they are positioned relatively to each other to establish such positions and permit the sole to be moved relatively to the shoe prior to the attachment of the sole without losing their relative positions. As illustrated, the shoe supporting means is adjustable for both right and left shoes. Moreover, means is also provided for locating the shoe longitudinally in the machine to insure proper action of the positioning and fastening inserting means.
With the above and other objects and features in view, the invention will now be described in connection with the accompanying drawings and Willthereafter be pointed out in the claims.

Fig. 9 is a bottom Aplan view, partly in section, illustrating the rear ends of the shoe gages and the mechanism for operating the gages as seen from below;
Fig. 10 is a perspective view of a hinged fastening member which is utilized with the present machine in practising the invention; and
Fig. 11 is a perspective view showing the outsole raised by an operator from the shoe bottom with the aid of the hinged member to permit the operator to apply solvent to cement on the outsole and shoe bottom.
The present machine comprises a horizontal base 2|] upon which issecured by screws 22 a supporting plate 24. Near its forward or righthand end, as viewed in Fig. 1, the supporting plate 24 has secured thereto a transverse guide plate 26 secured by screws 28. Extending vertically through slots in the base 20 and the plates 24, 26 is a bar 30 the upper end oi which is enlarged and provided with a wedge-shaped guideway 32 extending widthwise of the plate 24. Mounted for sliding movement in the guideway 32 is a slide member 34 provided with a T-shaped guideway 36 extending longitudinally of the machine or at right angles to the guideway 32. Slidably mounted in the guideway 36 is a second slide member 38 which carries a last pin 4l! arranged to enter somewhat loosely a thimble 42 which forms the hole in the heel end of alast 44, as shown in Fig. 1. The arrangement of the last support is such that the last pin 40 may be adjusted longitudinally for lasts of diierent lengths and also transversely of the machine for lasts for right and left shoes, the friction between the parts serving to maintain them in adjusted position.
At its lower end the bar Bil is pivotally connected by a pin 45 to ears 48 formed on the upper end of a threaded rod &3. Secured by screws 52 to the under side of the base 2i) is a U-shaped bracket 54 which extends downwardly at opposite sides of the bar 30 and has a cross portion 55 through which the rod 55 is threaded. By this means the last support 38, Il!! may be adjusted into different heightwise positions for lasts of different sizes, a pair of nuts 53 being threaded on the rod 50 to secure it in adjusted position.
Pivoted on a stud screw (5G, vertically mounted in the plates 25, 24 forwardly of the last support 38, is a curved arm 62 having a horizontal portion projecting outwardly beyond the plate 24. Adjustably mounted on the horizontal arm 62 is a toe rest Gli which is secured to the arm by a set screw 65 and has an upper end. shaped to engage the toe portion of a shoe, as shown in Fig. 1. The arm 52 may be swung about the vertical screw Sli into any desired lateral position relatively to the supporting plate 24 and, consequently, may be positioned to engage the toe ends of either right or left shoes. For operating on shoes of different lengths 4the toe rest may be adjusted along the arm 62 and secured in position by the set screw 65.
It is desired that the shoes and soles which are to be relatively positioned by the illustrated machine be located in a predetermined position lengthwise of the machine in order that the shoe and sole positioning mechanism may operate properly thereon and also in order that mechanism with which the machine is provided for forcing or pressing a fastening into the sole and shoe will be located in a position to engage the fastening. To insure that each last which is mounted on the heel pin lill and toe rest 64 will be located in a predetermined lengthwise position in the machine irrespective of the length of th-e last, an abutment $8 is provided for engaging the heel end of the last, the abutment being carried on the end of an upwardly curved l arm 'l0 formed on a substantially horizontal plate l2 which, in turn, is pivotally mounted on a pin lll for swinging movement lengthwise of the machine, the pin lll being carried in upstanding ears on a pair of brackets l5 secured by screws 'I8 to the supporting plate 2li. The plate 'I2 is urged normally in a counterclockwise direction about the pivot 'i4 by a compression spring 8i) mounted between the forward end of the plate 'i2 and the supporting plate 24, the limit of swinging movement of the plate l2 being controlled by a stop screw 82 threaded into the rear end of the plate and engaging the plate 24. Accordingly, the longitudinal position of the heel abutment 58 may be varied at will by adjusting the stop screw 82.
Secured to the supporting plate 24 by screws 85 is an upstanding bracket 8A which straddles the pivoted plate l2 and, at its upper end, is provided with two arms 88 (Figs. l and 9) having horizontal projections 9i) formed thereon. Secured by screws 92 to the projections 9|) is a plate Sil of substantial thickness which extends rearwardly of the bracket 88 for a considerable distance. At its rear end the plate 94 is supported by a strap S5 secured thereto by screws 98 (Figs.
1 and 9) secured at its lower end to the plate 24 by screws mii. Mounted for pivotal movement on the plate somewhat rearwardly of the bracket Sil is a bracket |32 having a circular base portion Hifi provided with a cylindrical projection |35 (Fig. l) extending downwardly therefrom, the projection |05 extending through a hole formed in the plate Q4 and being rotatable in the hole. The bracket 02 is maintained on the plate Qfi by a screw H6 threaded into the cylindrical projection E35, this screw also holding against the end of the projection |06, on the lower side of the plate 9d, a cam member ||2 (Figs. l and 9). The arrangement of these parts is such that the cam member is fastened by the screw il@ rigidly against the projection |05 but is rotatable with the bracket |52 relatively to the plate 9&5.
rThe bracket |32 has a forwardly projecting horizontal arm lill which is enlarged at its forward end lit and is provided with a vertical slot lili closed by a cover plate |23. Mounted for reciprocating movement in the slot H8 is a oar member i222 which is slotted at its intermediate portion to receive a compression spring |22 for normally maintaining the bar at the upper' limit of its vertical movement, the spring bearing at its upper end against the bar and at itsl lower end bearing against a projection |25 extending into the opening in the bar from the end portion HS of the arm IM. The upper limit of the movement of the bar is determined y the latter abutting against the projection |23. The bar |22 forms means for pressing or driving the fastening member referred to into the outscle and shoe bottom.
The bracket |92 is provided with two upstanding ears t28 between which is pivotally mounted on a pin 3i.l a lever |32. The lever |32 has a forwardly projecting arm carrying a roll |34 mounted on a pin E36 and arranged to engage the upper end of the bar or driver member |22 and depress it against the spring 24 to force the fastening member into the shoe and sole, as will be later described. The lever |32 has a rearwardly extending arm |33 provided on its end with a roll Hill pivoted on a pin |42. The weight of tarm |33 is sufficient normally to maintain the driving lever in an inoperative position with the roll |32 located above the end of the driver bar |22, as shown in Fig. 1, this position being maintained by stop screw I4@ mounted in the bracket |02.
It will be seen from the foregoing that the bracket 552, the cam M2, the driver bar |22, and the lever |32 may all be swung relatively to the horizontal plate about the axis of the cylindrical projection l'lin. This mechanism is swung from an inoperative position shown in broken lines in Fig. 2 to an operative position shown in Figs. 1 and 2, this latter position being determined by a stop Hi8 mounted in the plate 94. When the driver bar, driving lever, and associated mechanism are located in the position shown in Fig. l, the lever is in position to be operated upon by mechanism arranged to engage the roll lill) and swing the lever E32 about its pivot |35 to actuate the bar |22.
The mechanism for actuating the lever 4|32 comprises an upstanding plate or bar |59 extending through slots in the plates 20, 2|! and 94 and providedI at its upper end with a horizontal surface |52 (Fig. 8) for engaging the roll |40. A shoulder |561 is provided on the surface |52 by a projection |55 to insure that the bar |50 will not act upon the roll |40 unless the latter has been swung fully into operative position against the stop |40. The projection |56 on the bar |50 is arranged to engage the plate 94 and thus determine the lower position of the bar. At its lower end the bar |50 is pivotally connected by a pin |58 to a ltreadle rod |60 the lower end of which is connected by a pin |62 to a treadle |64 pivoted on a pin |66 mounted in a treadle support |60. Depression of the treadle |64 elevates the bar |50 to bring the surface |52 into engagement with the roll |40 thereby rotating the lever |32 and causing the member |22 to descend and drive the fastening member into the sole and shoe bottom. The weight of the parts |50, |00 normally maintains the treadle |64 in its elevated position.
The horizontal plate 94 is provided on its upper side with a slot |10 (Figs. 1 and 2) which extends lengthwise of the plate and in which is mounted for movement toward and from the shoe a slide |12. Adjacent to its rear end the slide |12 has pivotally connected to it by a screw |14 a rod |16 which extends upwardly at an angle and at its upper end is secured to the pivot pin |30. Consequently, when the bracket |02 and its associated mechanism, including the lever |32, are swung about the axis of the projection |06 from its inoperative to its operative position, the slide |12 is moved positively toward the shoe and, when the bracket |02 is swung in the opposite direction, the slide |12 is moved positively away from the shoe. At its forward end the slide |12 has adjustably secured to it by slot and screw arrangements |18 (Figs. 3 and 4) a horizontal plate |80 to the forward end of which is pvoted by a pin |02 a sole gage |84. As best shown in Figs. 3 to 6, inclusive, the sole gage |94 is provided with two forwardly projecting ears |06 40 adapted to enter corresponding slots 250 (Fig. 11)
formed in the rear portion of a short outsole A,
that is, a sole which terminates a short distance rearwardly of the heel breast line of the shoe.
The upper portion of the sole gage |04 comprises 4.5 a substantially horizontal plate arranged to extend over the rear portion of the sole engaged by the underlying projections |82 and thereby to prevent the sole from lifting out of engagement with the projections. Secured by a screw |90 50 (Fig. l) to a solid portion of the bracket 84 is a wire spring |90 which extends forwardly through an opening in the bracket and has a curled end arranged to engage the sole gage |92 when the slide |12 is retracted from the shoe 55 and to hold the gage in an upwardly inclined position, as shown in Fig. 5. When the slide |12 is moved forwardly into its operative position, the spring |90 is depressed by the slide to permit the gage to swing downwardly against the shoe 60 bottom, thereby locating the projections H06 in a position in which the slots 250 in the outsole A may be brought into engagement therewith and thereby locate the outsole relatively to the shoe bottom. Before the outsole is placed on the shoe 65 bottom in the position determined by the shoe gage |04, the shoe itself is positioned transversely of the machine on the shoe supporting member 40 and the toe rest 64, it being understood that while these members support the shoe in 70 substantially the proper position for receiving the sole, they do not position it in exactly the desired position relatively to the sole because the adjustments for right and left shoes have been manual adjustments which are not accurate and 75 also because the last pin 40 is preferably somewhat loose in the last thimble 42 so that the last itself is capable of some lateral or tipping movement relatively to the pin to enable the heel end of the shoe to be brought into proper alinement with the rear portion of the outsole.
The mechanism for positioning the rear portion of the shoe B on the supporting members 40 and 64 comprises a pair of gages |92 (Figs. 1, 3 and 9) pivoted for equal and opposite movement toward and away from the shoe on screws |94 secured to the under side of the plate 94. Rearwardly of the pivots |94 the gages |92 have arms |96 between which extends a tension spring |98 secured to each arm by a pin 200 and tending normally to hold the forward ends of the gages |92 in their open or retracted position. The arms |96 have curved inner surfaces 202 formed thereon which are arranged to be engaged by a wedge-shaped portion 204 on the forward end of a slide 206 which is mounted for reciprocating movement toward and from the shoe in a slot 200 (Fig. 9) formed in the under side of the plate 94, the slide 206 being retained in the slot by the cam ||2 and by a T-shaped guideway 209 provided by a pair of gibs 2 |0 secured by screws 2|2 to the lower surface of the plate 94. An
elongated slot 2|| is formed in the slide 206 topermit it to move relatively to the projection |06 which passes through the slot in the slide. The slide 206 is provided with a downwardly extending projection 2|4 and, secured in a hole in this projection by a pin 2 |6, is a horizontal rod 2 |0 which extends rearwardly and passes through a hole in a projection 220 extending downwardly from the lower surface of a second slide 222 mounted for sliding movement in the guideway 209. Surrounding the rod 2| 8 between the projections 2|4 and 220 is a compression spring 224, as shown in Fig. 9. The slide 222 is connected by a rod 226 to the cam ||2. The cam ||2 is provided adjacent tothe projection 2|4 with a cam surfacel 228 which is eccentric relatively to the axis of the cylindrical projection |06 of the bracket |02.
It will be seen from the foregoing description that when the bracket |02 carrying the driver |22 is swung about the aXis of the projection |06 from its inoperative to its operative position shown in Figs. 1 and 2, the cam ||2 will be rotated in a clockwise direction, as viewed from below (Fig. 9), and the rod 226 will move the slide 222 forwardly toward the shoe. Consequently, the slide 222 will, through the yielding connections described above, move the slide 206 forwardly toward the shoe to cause the wedgeshaped portion 204 to engage the curved surfaces 202 on the shoe gages |92 and separate the rear arms of the gages against the action of the spring |90 to cause the forward portions |92 to move equal distances toward the opposite sides of the shoe. The construction is such that if one gage |92 should engage the shoe before the opposite gage it will tend to move the shoe into a more centralized position until the opposite gage, which is likewise moving toward the shoe, engages the opposite side of the shoe. This action, however, is a yielding action due to the yieldable connections between the slides and, accordingly, the mechanism will yield unless the heel portion of the shoe is permitted by its supporting mechanism to move readily into the position determined by the shoe gages. If the shoe is not initially located in a central position the operator can readily adjust the heel portion of the shoe transversely by means of the slot 32 to locate the shoe suiciently close to its proper transverse position so that the shoe gages will engage both sides of the shoe and thereby position the shoe relatively to the operating instrumentalities. Reverse movement of the cam H2 through the rotation of the bracket |82 in to its inoperative position moves the rod 226 and the slide 222 positively into its rearward or inoperative position, thereby permitting the spring 224 to eX- pand. Since, however, the connections between the slide 222 and the forward slide 288 are not positive, this forward slide is not moved positively into its retracted position tolpermit the shoe gages to move outwardly away from the shoe. This movement is effected by the eccentric surface 228 on the cam H2 which is so positioned that it will engage the abutment 2|4 during reverse rotation of the cam and move it positively against the spring 224 into its rearward position, thereby permitting the gages to be moved away from the shoe by the spring |83. As illustrated in Fig. 3, the shoe gages SZ are provided on their shoe engaging ends with pads 238, which may be of leather, felt or similar material, to prevent the gages from scarring the shoe upper.
In the use of the machine illustrated herein, a fastening member 232 is provided for establishing the relative positions of the sole and shoe after they have been relatively positioned by the machine. This fastening member, as best shown in Fig. 10, comprises a hinge member similar to a pair of sugar tongs and having forwardly projecting legs 234, 236 the forward ends of which are provided with a plurality of sets of prongs 238 and 24|] which are spaced from each other and arranged to be pressed or driven respectively into the outsole A and the bottom of the shoe B between which the hinge member is mounted before the shoe is placed in the machine The fastening or hinge member 232 is preferably made of thin resilient material such as metal which is bent over upon itself to form the legs of the hinge. Adjacent to its rearward end the hinge member is provided with another set of prongs 242 whereby it may be readily secured to the heel seat portion of the shoe bottom. As shown in the drawings, the prongs on the hinge member may be conveniently formed by stamping them out of the metal and turning them in the proper direction away from the legs of the hinge. Preferably the prongs of each pair diverge slightly from each other to cause them to become further bent When they are driven into the work and thereby to become locked or clinched in the work.
The operator positions the hinge 232 with the rear prongs 242 extending toward the insole of the shoe B at its heel seat portion, the insole being designated in the drawings by the numeral 244. The overlasted marginal portions of the shoe upper B will, at this time, have been coated with cement 248, such, for example, as pyroXylin cement as shown in Fig. l1, and the marginal portion of the attaching surface of the outsole A will likewise have been coated with cement 248, the cement on these parts having been allowed to dry in the usual manner. After the operator has properly positioned the hinge 232 so that the forwardly projecting legs 234, 238 extend forwardly in overlapping relation to a metal shank piece or stiifener 249 on the shoe bottom, he presses or drives the rear prongs 242 into the insole thereby securing the hinge in proper position on the shoe bottom. It will be observed in Fig. 11 that the prongs 248 on the lower leg 236 of the hinge are spaced far enough apart widthwise of the shoe so that they will not engage the metal shank piece 249 but will preferably be in positions to engage the inner portions of the overlasted margin of the shoe upper. The operator mounts the shoe on the last pin 4U and toe rest 84, as described above, and adjusts the shoe supporting members manually until he has located them as closely as he can in the proper positions for the shoe being operated upon. The last and shoe will be capable of some further lateral adjustment because of the slide 34 and the loose t of the last pin 48 in the last thimble 42 to permit the shoe gages to centralize the shoe exactly with the sole which is to be located thereon. The operator also adjusts the heel abutment 88, if necessary, to position the shoe longitudinally. He next places the short outsole A, provided at its rear end with two slots 250 (Fig. 11) upon the bottom of the shoe and in approximately the proper position relatively thereto and, while holding the outsole in such position, he swings the bracket |82 and the associated mechanism, including the driver |22 and the driving lever |32 from the position shown in broken lines in Fig. 2, to the position shown in Fig. l. This action moves the sole gage |84 forwardly over the heel seat portion of the shoe and into such position that the projections |86 thereon may be readily brought into engagement with the corresponding slots 259 in the outsole. The rear portion of the outsole B having been thus located laterally and longitudinally of the shoe bottom, the operator can readily shift the forepart of the outsole by hand until it is properly located Widthwise of the shoe bottom.
While the sole gage |84 is moving into operative position, the shoe gages |92 are also moving yieldingly into engagement with the opposite sides of the heel portion of the shoe, this action being accomplished, as described above, by rotation of the cam H2 whereby the slide 222 is moved forwardly toward the shoe to actuate the forward slide 20B yieldingly through the spring 224 and thus to cause the wedge 284 on the latter slide to separate the rear arms of the shoe gages |82 and bring their forward ends into engagement with the shoe. The sole and shoe having been properly positioned relatively to each other, the operator depresses the treadle |64 to actuate the lever |32 and to cause the driver member |22 to descend against the outsole A and press or drive the prongs 238 and 246 on the opposite arms of the hinge 282 into the outsole and the insole 244, respectively, thereby establishing the relative positions of the rear portions of the sole and shoe widthwise and longitudinally while the sole and shoe are held in such positions by the gage members |34 and |92. The operator may then remove the sole and shoe from the maclL'ne and, as shown in Fig. 11, raise the outsole away from the shoe bottom and, by a brush 252 or similar implement, apply solvent to the cement on the inner surface of the outsole A and, if desired, to that on the shoe bottom. As will be seen from Fig. 11, this operation may be easily accomplished with the aid of the hinge member 232 without losing the previously established positions of the sole and shoe.
