Serial No. 659,150.

The present invention relates to the manufacture of shoes having Louis heels, or heels of that general type, and is herein illustrated as embodied in a machinebspecially adapted for performing theoperation of laying'the heel breastleaf orsplit portion of the sole against the breast of a Louis heel after the heel has been attached to the shoe.

It is customary to cover the breasts of wooden Louis heels after the heels have been attached to the shoes by applying to eachheel breast a thin leaf or flap which" has previously' been formed by splitting the rear portion of thesole. Usually, for convenience in fitting the heel seat or for other reasons, the'sole is split along the shank to a point somewhat forward of the line where thebase of the heel breast will be located. Acoating of cement or other adhesive is' applied to the inner face of the leaf and thereafter the leaf is manually laid against the shankand the he'el'breast with'th'e' aidof a bone or othersuitable implement for rubbing and pressing the breast leaf intoplace. After the leaf has been thus manually laid in place, a heel breast clamp is employed to clamp the f leaf firmly against the heel breast and hold it under pressure duringthe drying and set ting ofthe adhesive. The laying of the leaf manually as above described is a comparatively slow operation and considerable care is required if the leaf is to be'lald smoothly throughout its entire area and the operation uniformly performed upon different shoes.

One object of the present invention is to" provide a practical machine for laying the heel breast leaf, and one whichwill perform that-operation more quickly and efficiently than it can be'performed' by hand and in such F the Work to apply substantially rolling pres vided a pressure-applying pad of rubber or other suitable yielding material shaped to conform under compression to-the contour of the heel breast and adjacent shank portion.

of the sole, and means for operating said pad first to move itinto engagement with the;

forepart of saidshank' portion at its point of highest transverse convexity then by con tinued movement of the'pad in' the same geii eral direction to apply pressure progressively outwardto the opposite lateral edges of the" shank and rearwardto and along a portion of the'base ofthe heel breast; and thereafter to; rock said pad about a substantially fiXed point adjacent to the base of the heel breast to cause the pad to apply pressure progres sivelyf upward, alongtheheel'breast to the tread face end 'of the heel, all for thepurpose of laying said" leaf smoothly against the shank and heel breast. Preferably, the

pressure-applyingpad is secured to a carrier 1 movablymounted, upon a carrier support which is adapted for vertical swinging move-f ment to lower the pad into engagement with the shank portion of'alasted shoe suitably supported beneath the pad. After this downward movement of the pad has been of fected to lay the leaf along the shank of the sole, a sliding movement in an arcuate path is imparted tothe pad carrier to move it rela tlvely to theswingmg carrier support for the purpose of rocking the pad to lay'the leaf against the heel breast. The illustrated pad carrier and carrier support are operated by means of'mechanisrn controlled by a onerevolution clutch sothat at each cycle of oper ations of the machine the pad is caused to perform a single leaf-laying operation and then to be retracted from engagement with the shoe to permit the removal of the shoe which hasbeen' operated upon and its replacement by a shoeto be operated upon.

Othernovel features of construction by which the inventionis-ca'rried out will be set erating' the leaf-laying pad.

The illustrative machine comprises a suport 2 for a lasted shoe, aback rest 4 for the heel of the shoe, anda movable pad 6 for layingthe heel breast leaf. These parts are arranged in front of a hollow head or frame 8 within which is mounted mechanism for op- The head or frame 8 is secured to the upper end of a standard 10 and the pad-operating mechanismis driven by means of a motor 12 which is supported upon a bracket or shelf 14 that is adjustably secured to the rear of the head 8. V

The support 2 for the lasted shoe consists of an upright arm formed with a rearwardly curved lower extremity which is rigidly secured to the front of the head 8. A last pin 16 surmounts the arm or support 2, adapting the latter to support a last such as indicated at 18 in Fig. 1. The last 18 is fitted within a shoe 20 having an attached Louis heel 22 and a heaf or flap 24 which has been split from the sole 2 5 of the shoe and is to be utilized to cover the breast of the heel.

To support the heel against the backward thrust of the leaf-laying pad 6, the back rest 4 consists of a roller of a diameter such thatthe curved face. of the roll will substantially conform to the concave portion of the.

cry of the back rest roll 4 is hollowed or concaved. in the direction of the axis of the roll, as shown at 26 in Fig. 3, to conform substantially to the horizontal or transverse convex curvature of that portion at the rear of the heel which is engaged by said roll. The

roll 4 is mounted to turn freely upon a pin 28, the opposite ends of which are fixed in the arms of a yoke 30. The yoke 30 is mounted for a limited amount of vertical swinging movement to enable the back rest roll to adjust itself readily to heels of different heights; To this end a stud 32, which extends rearwardly from the closed end of the yoke 30, is received within a split sleeve or socket member 34 and is rigidly but adjustably clamped therein by means of a binding screw 36 arranged to contract the sleeve about the stud. The sleeve or socket member 34 is arranged to rock about an axis perpendicular to the length of the stud 32 and to this.

end a bearing lug 38 depending from said sleeve is pivotally mounted upon a rod 40 which is parallel to the axis of the roll 4 and is supported at its opposite ends in bearings 42 formed on the frame 8. To limit the downward swinging movement of the back rest roll 4, a stop linger 44 projecting forwardly from the bearing lug 38 is arranged to engage an adjustable abutment in the form of a screw 46 which is threaded into the frame 8 and provided with a suitable lock nut 48 for binding it in adjusted position. After loosening the lock nut 48, the screw 46 may be turned to vary the lower limit of vertical swinging movement of the back rest roll and thus to vary the position of the latter when it is idle, i. e., when no shoe is present upon the support 2. This adjustment should be varied in accordance with the height of the heels to be operated upon, it being desirable that the roll 4, when idle, should be supported in a position lower thanthat which it is to occupywhen engaging and supporting a heel and that it should be free to be lifted by contact with the heel of the shoe.

Being positioned as above described when a lasted shoe is being mounted upon the support 2, the roll 4 is first engaged by the rear portion of the heel at a point adjacent to the heel seat end of the heel and as the shoe is swung more or less in the general direction of the arrow 50 in Fig. 1, in the act of adjusting the shoe firmly upon the last pin 16, the roll 4 is caused to ride upwardly along the slop ing rear face of the heel until it is finally elevated to the position in which it is illustrated in Fig. 1 and wherein it has adjusted itself to the contour of the vertically hollowed or concave portion at the extreme rear of the heel and serves very efficiently to support the heel against the backward thrust of the leaflaying pad. By loosening the binding screw 36 and shifting the stud 32 longitudinally in its socket, the roll may be conveniently adjusted either forwardly or rearwardly in accordance with variations in the size and style of the heel to be operated upon, thereby adapting the roll rigidly and reliably to support the heel.

The leaf-laying pad 6 is made of yielding resilient material such as soft rubber and depends from a carrier 52 which overlies the rear of the shoe, the pad being rigidly secured to said arm in'any suitable manner. The pad 6 is so shaped that when swung downwardly it may be brought initially into contact with the shank of thesole at a single point only such as that indicated at 54 in Figs. 1 and 4, this point being located somewhat forwardly of the split portion of the shank and centrally of the transverse arch thereof. The movement of the pad 6 is then continued in-the same general direction and thereafter it is rocked about its area of contact with the sole, as will hereinafter be described, so that the pad is compressed against the shank and heel breast. The shape of the pad is such that as it is thus actuated and compressed, it will function to apply pressure to the leaf so as to lay it progressively rearward along the shank and heel breast to the top-lift end of the breast and also progressively outward from the longitudinal median line of the shank to the opposite lateral edges thereof.

To enable the pad 6 to lay the breast leaf in the manner above describechthe pad-carrying means and the actuating mechanism therefor are constructed and arranged as follows: The pad carrier 52 is of the irregular shape shown in Fig. 1, comprising a depend ing leg 60 towhich the-pad is secured and a rearwardly extending curved leg 62 which lies between a pair of supporting arms64, the latter being arranged parallel to each other and pivotally mounted at theirrear extremities upon spaced apart but axially alined studs 66 that are fixedly secured in upward extensions 68' of the frame 8. The opposite end portionsof the carrierleg 62 are slotted, as shown at 70, to receive bolts 72 which extend transversely through the supporting arms 64 and connect the latter to swing Vertically in unison about the pivot studs 66. The slots 70 are elongat'ed' lengthwise of the carrier leg 62 and are of arcuate shape, the longitudinal center lines of the slots having the same radius and a common center of cur vature which is located preferably somewhat below and at the rear of the heel'breast when the pad 6 is depressed into its operative posit on in engagement with the sole. The bolts 72 extend loosely through the arcuate slots 70 and the above described shape and arrangement of the slots is such as to permit rearward movement of the pad-carrier 52 relatively tothe carrier supporting arms 64s0-as to rock the pad rearwardly after the leaf has been laid against the shank portion of the sole to cause the rear face of the padto press the remaining unattached end of' the leaf against the heel-breast will be hereinafter more fully described.

To move the pad 6 into leaf-laying engage ment with the shoe, the supporting arms'64 are swung downwardly in'unison about their axially alined pivot studs 66 intotheiposition shown in Fig. 4, and at the completion of the leaf-laying" operation, the pad 1s returned to the position shown in Fig. 1 by acorresponding upward movement of said supporting arms. The supporting. arms 64 arelowered and raised by cam-actuated means compris ing a lever 7 4 and a connecting rod 76 which connects the forward end of said lever with the arms 64, the upper end of said rod carrying a yoke 78 the sides of which lie adjacent to the outer sides of the arms 64 and are pi votally connected therewith by the rearnrost bolt 72. The-lever 74 is fulcrumed at its rear extremity upon a fixed rod 80 and carries a cam roll 82 which rides in a groove 84 formed in a cam disk 86, the latter being fixed upon a cam shaft 88 that is journaled in suitable bearings in the sides of the frame 8. The cam shaft 88 is driven from the armature shaft 90 of the motor 12 through a train of gearing comprising a pinion 92 that is fast upon the motor shaft 90, an idler pinion 94 that is suitably mounted upon the frame 8, and a gear 96 which is loosely mounted upon the cam shaft 84 and is adapted to be connected therewith by means of a foot-controlled clutch 98.

As shown, the clutch 98, comprises a member 100, (Fig. 8) whichpartially encircles the shaft 88, and is provided with a pin 102 that is arranged to slide freely through a collar 104 fixed to the shaft 88. The pin 102 is adapted to be interposed in the path of movement of a pin or lug 106 carried by the hub' of the gear 96. The clutch member 100 is normally maintained by a spring (not shown) in a position to connect the driving pulley operatively to the drive shaft. An inclined cam face 108 on the clutch member 100 operates, upon engagement with the upper end of a bell-crank lever 110, (see also Fig. 1) to disconnect the clutch member 100 and the shaft 88 from the driving? gear 96. The'lever 110 is mounted to rock upon a fixed pivot stud 112 andis-arranged to be actuated by a treadle-rod 114, a suitable spring (not shown") being utilized which tends normally to holdthe upper extremity of the bell-crank lever 110 in engagement with the cam face 108 to hold the driving clutch member 100 disengaged from the driving gear 96. The clutch 98 is actuated tostart the machine by depression of a foot treadle (not shown) connected to the lower endof the rod- 114.

As the supporting arms 64 swing downwardly to bring the pad 6 into engagement with the shank of the sole at the point 54, and further to'apply pressure to the breast leaf progressively rearward along the shank and also progressively outward to'the lateral edges thereof,-the position of the pad-carrier 52 relatively to thesupportingi arms 64 re mains unchanged; Thepad conforms under compressionto both the'longitudinal concavity and the transverse convexity of the shank and functions to lay the'breast leaf progressively rearward from the point 54 and also outward at both sides of the longitudinal median line of the shank so that the leaf is subje'cted to what is, inelfect, both a longitudinal and transverse rolling action. This is due partially to the path of movement of the pad relatively to the shoe and partially to the peculiar shape of the lower face of the pad and the angle of presentment of said face to the sole whereby the pad is compressed into conformity with the contour of the shank as above described. It will be understood that although the action of the pad is not a wiping or rubbing action the pad functions effectually to smooth out any wrinkles which may extend lengthwise or crosswise of the shank. The rear portion of the lower face of the pad 6 is shaped so as to conform readily under compression to the concave curvature of the heel breast adjacent the shank. I/Vhen the pad 6 has been depressed to the limit of its downward movement, it appears substantially as shown in Fig. 5, the breast leaf 24: being held under pressure against the shank of the sole and upwardly to a certain extent along the curved base portion of the heel breast. It will be noticed, however, that the rear face of the pad 6 is not in pressure-applying engagement with the greater portion of the heel breast and that the leaf has not yet been laid thereagainst.

After the pad has been depressed by the above described downward swinging movement of the supporting arms 6A, the pad carrier 52 is moved rearwardly, relatively to the supporting arms 64;, to cause the pad to be rocked backwardly about a substantially fixed point adjacent to the base of the heel breast to apply the unattached end portion of the breast leaf to the relatively flat portion of the heel breast and to press it into the recess or scallop 116 at the tread face end of the breast.

To effect this backward rocking of the pad,the pad-carrier 52 is connected by a link 118 with the upper extremity of a cam lever 120 which is fulcrumed upon a rod 122 that is fixedly supported at its ends in the side members of the frame 8. At its lower end, the lever 120 carries a cam roll 12% which is received in a cam groove 126 in the cam disk 82. The lever 120 and cam groove 126 are so designed that while the pad 6 is moving downwardly into engagement with the shoe, and at all times except while the pad is being rocked by the action of the cam lever 120, the axis of the pivotal connection between said lever and the link 118 is coincident with the common axis of the pivot studs 66 about which the pad carrier supporting arms 64 are swung. Thus the pad is free to move into its initial engagement with the shoe without its movement being influenced or modified by the connectiorlis between the pad-carrier and the cam dis z. 7

After the leaf has been laid against the shank portion of the sole, however, the pad is rocked by the action of the cam lever 120 as above described to complete the leaf-laying operation. This rearward rocking of the pad 6 moves it into the position shown in Fig. 6. In moving into this position the pressure of the compressed pad is concentrated at the portion of the shank close to the base of the heel breast and along the adjacent curved portion of the heel breast. The angle between the rear face of the pad and; the opposed breast face of the heel is gradually closed and the breast leaf is laid progressively upward along said heel breast to the tread face end thereof. The pad is laterally compressed as it is forced rearwardlyagainst the heel breast and the yielding material of the pad is forced into the scallop or cavity 116 in the heel breast and the leaf is smoothly laid over the sides of said scallop. The rocking movement of the pad is insuflicient to relieve to an undesirable extent the degree of compression with which the leaf is held against the shank portion of the sole. After the leaf has been laid in the above described manner the pad 6 is rocked rearwardly to the position shown in Fig.4 5 and thereafter is returned to the initial position shown in Fig. 1, thus completing the cycle of operations of the machine. Upon the return of the pad 6 to initial position, the clutch 98 is thrown out and the operation of the machine is arrested to permit the removal of the shoe and the replacement of another in position to be operated upon.

It will be understood that to obtain satisfactory results from the use of the present machine a quick-drying cement should be used upon the breast leaf. The length of time required for each cycle of operations of the machine, and consequently the amount of time the breast leaf is held under pressure against the shank and heel breast, is determined by the speed of the motor 12 and the ratio of the speed reducing gearing connecting the motor with the cam shaft. By changing the ratio of said gearing, the length of time consumed at each cycle of Operations may be varied to enable cements of different drying or setting properties to be successfully employed. In practice it happen at times that the breast leaf will be curled backwardly away from the shank and heel breast more or less when the shoe is positioned for the leaf-laying operation. In such cases it may be desirable for the operator preliminarily to wipe the free end of the breast leaf along the heel breast by hand sufficiently to insure that the leaf will be so positioned as properly to be engaged and laid by the pad 6.

By reason of the above-described creeping or rolling of the pad 6 over the breast leaf the latter will be laid without being subjected to any frictional drag or pulling action such as would result from the wiping or rubhing of the pad over the breast leaf, and which would be liable to stretch or distort the leaf and to injure its surface inasmuch as the leaf is moistened and softened by the cement before it is laid. The leaf will be laid smoothly and without injury thereto by means of the pad 6 and the results will be uniform for the various shoes operated upon. Furthermore, by means of the present power-actuated machine the leaf-laying operation may be accomplished much more quickly than by hand.
