Claims.

This invention krelates to. machines for use in applying pressure to shoe bottoms `and more particularly kto means for relatively positioning a shoe and a plurality of shoebottom members prior to the application of pressure thereto.

One rtype of .womens ,shoefthat has recently been popularized is the so-calledv platform sole shoe. This typeof shoe has a thick midsole positioned between the shoe and the outsole, this midsole being known as a platform. In order properly to join the shoe, the midsole and the outsole together by cement by applying pressure between the parts,v it is necessary that the parts be accurately positioned relative to one another prior to the application of pressure thereto. It is an object of this invention therefore to provide .improved means for relatively positioning a plurality of shoe parts prior to the application of pressure between the parts.

In the illustrated embodiment of the inve tion the positioning means .are incorporated in a machine of the type illustrated in Letters Patent of the UnitedStates 2,047,185, granted June 14, 1936, .on an application of M. H, Ballard et al. In accordance with one feature of the invention, feelers are provided for finding and holdingthe forepart of a sole placed on a pressure-receiving pad and associated with these feelers are gages arranged to position the forepart of a midsole relative to the outsole and position the forepart of a shoe relative to the midsole, A pin adjustable longitudinally of the pad is arranged to engage a hole punched in the heel seat of the outsole to position the heelend of the outsole widthwise of the pad, .this pin being carried by a resilient tongue arranged to be located between the outsole and a midsole or platform sole placed thereon. Gages are provided for positioning the heel end of the midsole relative to the outsole and other gages are provided vfor positioning the heel end of the. shoe relative to the midsole. The various gages are arranged to be adjusted to provide the proper alinement and overhang of the various parts relative to one another.

These and other features of the invention will be described in detail in the specication and illustrated in the drawings, in which Fig. 1 is a side lelevation of a pad box with which is associated one form of positioning means for the forepart of a shoe, a midsole and an outsole and one form of positioning means for the heel ends of these members, the heel end positioning means being shown in section;

Fig. 2 is aplan View of the pad box and the positioning means;

Fig.A 3 is a perspective View of one of the positioning devices for the forepart; and

Fig. 1 is an end lelevation of the positioning device of Fig. 3.

A pad box il) which may be similar to that illustrated in the Ballard et al. patent referred to above is provided with a pad l2 for receiving the shoe parts for the application of pressure therebetween upon downward movements of a toe pad Hand a heel abutment It, these members being arranged to move downwardly after the shoe` and shoe bottom members have been properly positioned on the pad.

- The positioning means vfor the heel end of the shoe and the shoe bottom members are mounted on a support I8 p ivoted at 28 to a support 22 adjustably secured bya screw 24 to an arm 2S. The screw 24 passes through a slot in the arm 26 to provide for lengthwise adjustment of the support I8 relative to the pad. The arm 26 is carried by a vertical slide 28 and is urged upwardly to the position illustrated in Fig. 1 by a spring 3l) acting between the slide and a bracketI 32 rigid with the pad box l0. The support I8 is maintained in the desired position of adjustment relativeto the support 22 by a screw 34 threaded through the support 22 the adjacent portion of the support I8 being maintained in engagement 4with the screw by a compression spring 36.

For locating the heel end vof an outsole transversely rof the pad, a sole-receiving pin 38 (Fig. 2)., arranged to be engaged with a hole punched in the heel seat of .an outsole, is carried by a resiIient tongue40 which is in turn secured to an arm 42Hpivoted .at 44 to a slide 46 arranged for movement lengthwise of the pad box in the support I8.- A spring pressed detent 4l (Fig. 2) engaging an elongated recess in the slide 46 limits the sliding movement thereof. A spring 48 secured to the slide ,46 and to the arm 42 urges the arm downwardly to maintain the tongue 40 in engagement with a solev placed on the pad. In order to raise the tongue 40 and pin 38 away from the pad box to permit the insertion of a solo therebetween, the arm 42 is provided with a -handle y:lill by which the arm 42 may be moved about the pivot 44 against the tension of the spring 48. y

Also carried by the support l'8 is a pair of arms 52 and 54 (Fig. l2) pivoted about horizontal axes by 'Pills 5,5 to arms 5B which are arranged for equal and opposite movements. These -arms are arranged :to be moved toward each Vother by a compressien spring 5D .acting on a slide 5.8 .in a

manner .fully disclosed in Letters Patent of the United States 2,005,755, granted June 25, 1935,

on an application led in my name. The arms '52 and 54 carry at their inner ends gages 62 and 64 arranged to engage a midsole placed on the outsole to position the heel end of the midsole relatively thereto. The gage 62 is pivotally connected to the arm 52 by means of a pivot pin 66, the gage 62 having a rearward extension 68 through which is threaded a screw arranged to engage the adjacent surface of the arm 52 to adjustably position the gage relative to the arm. A spring '|2 acts between the gage 62 and the arm 52 to maintain the screw '|0 in engagement with the arm 52. This adjustment of the gage 62 relatively to the arm 52 provides for lateral adjustment of the midsole relatively to the outsole.

The gages |32 and 64 are maintained in the proper heightwise positions relative to the pad by means of stops 16 (Fig. 1) arranged to engage the pad l2, these stops being formed at the lower ends of screws 18 passing through the arms 52 and 54. Adjustment of the screws 18 relatively to the arms causes vertical adjustment of the arms relatively to the arms 56 thereby permitting heightwise adjustment of the midsole gages relatively to the pad.

In order to position the heel end of a shoe laterally relatively to the midsole, shoe gages 80 are provided, these gages being formed at the ends of arms 82 carried by the support |8 and arranged for equal and opposite movements by a tension spring 84 acting upon a slide 86, the slide being connected to the arms 82 in the manner shown in my earlier patent. The lateral position of the shoe gages 80 relative to the midsole gages may be adjusted by rotation of an adjusting arm 88 as explained in my earlier patent and the heightwise position of lthese gages may be varied by adjusting the position of the support I8 by the screw 34.

The gages thus far described determine the relative positions of the heel ends of the outsole, the midsole and the shoe widthwise of the pad, the lengthwise positions of these members being determined by gages to be described. Gage assemblies 90 mounted on the outer ends of arms 92 are provided for engaging the foreparts of the shoe, the midsole and the outsole at the opposite sides thereof. The gage assemblies 98 are arranged to be moved inwardly toward one another by swinging movements imparted to the arms 92 upon treadling of the machine by the operator, as described in the Ballard et al. patent, after the sole has been placed on the' pad.

One of the gage assemblies is illustrated in detail in Figs. 3 and 4 and comprises a-gage or feeler member 94 extending inwardly of the pad box at the lower end of an arm 96 depending from ythe arm 92. '.Ihe outer end of the arm 92 is provided with ways 98 and |00 for slides |02 and |04 respectively. The slide |02 is formed with a downwardly extending arm |06 the lower end'of which is provided with a gage |08 extending above and substantially co-extensive withthe feeler 94. The slide |02 is held in adjusted position relative to the arm 92 by means of a screw IIO threaded through an upwardly extending boss ||2 secured to the slide |02. The screw ||0 is provided with collars ||4 engaging opposite sidesl of a pin ||`6 (Fig. 4) secured to the arm 92 to prevent axial movement of the screw H0 whereby rotative movement thereof causes the slide |02 to be moved to adjust the gage |08 relatively to the feeler 94. The gage |08 is arranged to engage the midsole M, as indicated in Fig. 4, whereby the position of the midsole relative to the outsole O is determined by adjustment of the gage |08 relative to the feeler 94 thereby determining the amount of the overhang of the outsole relative to the midsole, if any.

In order to determine the position of the forepart of a shoe S relative to the midsole, a. gage extending above the midsole gage |08 is connected to the slide |04. This slide is maintained 'in the desired position of adjustment in the same ball line are carried at the outer ends of arms |24 which are arranged to be swung inwardly upon treadling of the machine, as illustrated in the Ballard et al. patent, and associated with these feelers are gages |26 arranged to determine the lateral position of the outsole relatively to the midsole in the vicinity of the ball line.

Before placing an outsole on the pad box, the forepart gages and feelers carried by the arms 92 and |24 are separated as are the midsole gages 62 and 64 and the shoe gages 80 at the opposite end of the'pad box. The midsole gages 62 and 64 are maintained in open position against the force exerted by the compression spring 60 by means of a bell crank lever |28, the end of which carries a roll |30 arranged to engage the slide 58 when the bell crank lever is moved about its pivot in a -clockwise direction from the position illustrated in Fig. 2. The shoe gages are maintained in spaced-apart position against the force exerted by the tension spring 84 by a link |32 connected at one end to the slide 86 and pivotally connected at its other end to mechanism operated upon swinging the toe and heel abutments |'4 and I6 into pressure-applying position to permit movement of the slide 86 by the spring 84 to move the shoe gages toward one another as explained in my aforementioned patent.

The outsole is placed upon the pad by the operator, the position of the heel part of the outsole widthwise of the pad box being determined by the pin 38 carried by the tongue 40, the tongue being swung upwardly before placing the sole on the pad by depression of the handle 50. The position of the sole lengthwise of the pad is at the discretion of the operator and the heel-engaging pin 38 is adjustable longitudinally of the pad box since it is carried by the slide 46. Upon placing the sole on the pad and engaging the hole in the heel end thereof by the pin 38, the operator treadles the machine which causes a bell crank lever |40 pivoted at |42 to the pad boxto be swung, thereby operating a link |44 which permits the arms 92 to swing toward one another until the feelers 94 nnd the opposite sides of the forepart of the outsole whereupon movement of these arms will stop. Likewise the arms |24 move inwardly until the feelers |221'carried thereby iind the opposite sides of the outsole .in the vicinity of the ball line. At the same time, a link |46 is operated to rotate the'bell crank lever |28 in a counterclockwise direction whereby the compression spring 60 is effective to move the midsole gages 62 and 64 inwardly. At this time, since the midsole has not been placed on the out sole, these gages may move inwardly of the outsole, the stops 'I6 which space these gages above the pad box being permitted by reason of their curvature to ride over the edge off the outsole. In order to move these gages apart during the pacing of the midsole on the outsole, a handle l 50 connected to the slide 58 is provided whereby v the operator may move the slide against the vforce of the yspring to to open upthese gages thereby permitting the -heel end of the midsole to be placed on the outsole.

The outsole is now held in place by the forepart feelers and the heel-engaging pin 38 and is ready to ha-ve the midsole placed thereon. 'The operator places the midsole on the outsole with the toe end or" the midsole in engagement with `the gages im?, the lateral position of the midsole relative to the outsole in the vicinityof the ball line being determined by the gages 126. The

gages 62 and Eid lfor the heel end of the midsole will now be' moved lapart by the handle I 50 whereupon the heel end of the midsole is placed on the outsole and the handle |50 released so that the heel end of the midsole will be moved into proper position relative to the outsole. The shoe is now placed on the midsole, its position at the toe end being determined by the shoe gages and at the ball line by the gages |26. The toe and heel abutments i4 and I6 are now moved into register with the shoe, this action permitting movement of the shoe gages inwardly toward one another under the force exerted by the Ispring Si as described `in my earlier patent, thus positioning the heel end of a shoe in proper register relative to the midsole.

It will thus be seen that three parts of a shoe, such as an upper, a midsole and outsole, may be readily positioned in a predetermined manner relatively to one another by means of the novel arrangement of the various gages which are relatively adjustable to provide for varying amounts of overhang of the various parts. The various gages used to effect the proper alinement of the shoe parts to be secured together may be readily attached to a machine of the type illustrated in the Ballard et al. patent although their use is not limited to a machine of this type.
