MACHINE FOR AFFIXING HEELS TO SHOES.

Application filed March 31, 1920.

To all whom c't'mag concern:

Be it known that we, ISABELLE HnNNn and JOHN L. Pnrio, citizens of the United States, 'esiding in the city and State of New ork, have jointly invented Machines for ikihx ng Heels to Shoes, of which the following is a specification.

The invention is a machine for afiixing heels to womens shoes and slippers. heels are cemented to the bodies of the shoes, and the object is to provide means for applying powerful pressure to force the surface bodies together while the cement s fresh and for holding the pressure until it is set, the means being of such nature as to produce a superior union, while saving time and increasing output by reason of the facility of the operations and the comparatively short period during which it is necessary for the articles to remain clamped. Heretofore the heels have been held forcibly in place on the shoes until fast by means of separate, manually tightened screw clamps, which are laborious to apply and exert a moderate pressure, requiring the shoes and heels to be clamped for a longer time. The machineof this invention is a rotatable table or carrier adapted to be loaded with a substantial number of shoes, which ar put on and taken off as their positions on the table come opposite an attendants station, the table being provided in circular series with shoe-support iiig and heel-pressing instrumentalities, which are brought successively into position where they are acted upon by power-applying means, the attendant or operator releasing a shoe with its afixed heel which has remained in the machine for the necessary length of time, removing the same, putting on a new shoe, and applying heavy inomentary pressure thereto to clamp the heel and body together with the fresh cement between them, which pressure is at once held by an automatic, releasable clutch, then turning the table a step, releasing the clutch holding the next shoe and heel under clamping pressure, taking oil thatshoe, and putting on another, the operation being continued in the same manner indefinitely. The construction and relation of the supporting and clamping parts are such that the shoes and heels automatically find the proper angle under pressure so that the applied force will fix the heels firmly and truly. The general nature and particular features of the Specification of Letters Patent.

apparatus will be more fully understood as the specification proceeds.

In the accompanying drawings forming a part hereof, illustrating the present preferred embodiment of the invention:

Figure 1 is a view of the machine, mainly in central vertical section, with portions lying in the plane of section partly in section and partly in elevation for clearness of illustration, only two sets of shoe-supporting and heel-pressing instrumentalities being shown, the fulcrum hub for the heel-pressers being partly broken away, one of the two heel-pressers shown being depressed upon the heel of a shoe by the common treadle means, which is engaged therewith and forced downward as it would be by the pressure of the foot of the operator, the other heel-presser being shown in the elevated position where it is held by its springs, and without a shoe upon its corresponding shoemount, and this shoe-mount being shown adjusted farther out than the mount at the opposite side of the view, it being understood that this view is illustrative of the mechanism rather than of a typical operating condition;

Fig. 2 is a plan view of the complete machine, the rocking shoe-mounts all being shown as if standing with their pins straight up, whereas in Fig. 1 they are tilted, and the slide at the extreme right of the view bearing a shoe-mount and toe-rest being shown adjusted outward to the limit;

Fig. 3 is an enlarged elevation looking at the front of the machine, that is to say at the operators station, the lower part of the support being broken away, one of the radiating arms of the table being shown projecting directly forward and being sec tioned, the corresponding slide with its shoemount and toe-rest being omitted, the corresponding heel-presser being in the raised portion and its draw-bar in engagement with the draw-bar of the treadle, draw-bars of two adjacent heel-pressers (not seen) being shown with their upper portions broken away and the lower part of one in vertical section, and one of them being depressed and the other elevated; Fig. 4 is a fragmentary section on a still larger scale taken in a vertical radial plane passing through the draw-bar of one of the heel-pressers with its serrated holding rackv and adjacent clutch mounted on the table;

Fig. 5 is a sectional elevation, looking toward the left in Fig. 4;

Fig. 6 is an end view of one of the table arms with its slide, toe-rest and shoe-mount;

Fig. 7 is a horizontal section through the two-part fulcrum hub of the heelpressers taken at the plane of cleavage, the inner portions of the presser levers being shown in plan, with the exception of one which is in horizontal section;

Fig. 8 is a fragmentaryhorizontal section showing the device for arresting the rotation of the table at its several operating positions;

Fig. 9 is a cross-section through the stem of one of the toe-rests; and

Fig. 10 is a horizontal section through a portion of the table and one of the heelpresser draw-bars passing therethrough.

The machine has a base 1 and a hollow standard 2, forming a support for a rotatable table 3, which is preferably constituted of a disk 4 and numerous radiating arms 5. A ball-bearing 6 is arranged between the under side of said disk and the top of a collar 7 on the upper end of the standard. A stationary vertical shaft or post 8 extends upward from the base within the standard, through a side-bearing opening in the table disk and for a substantial distance above the latter.

The table is a rotary carrier for a circular series of supporting and clamping instrulnentalities, whereby the shoes and heels are supported and forced together under heavy pressure, which is held until the cemented union is complete. The carrier brings these instrumentalities successively to the control or actuation of means operated by the attendant to apply the pressure. Each shoe after traveling around the circuit of the ma chine under pressure is ready to be taken off andhave a fresh one put in its place. One operator is suflicient for the machine, releasing and taking off the finished shoes as they come in front of him, putting on and applying the pressure to the freshshoes, and turning the table onestep after each exchange. It will be obvious, however, that there might be two attendants, one to take off and put on, and the other to press, and that depending upon the size and speed of operation of the machine it is not necessary in all cases that the shoes complete an entire circuit before their heels are sufiiciently set for the shoes to be removed, and, further, that operations which for simplicity are performed manually or by the muscular force of the operator might be effected automatically.

Returning now to a brief descriptionpf the preferred simple embodiment of the 1nvention, the table arms 5 are secured to the disk 4 by screws 9, 10. The outer and major portionof each arm is constituted as a guide, by means of side bars 11 and overhanging strips 12, secured by screws 13 (Fig. 3), and

at the outer end of the guideway is a stop 1 1. In each guideway is a radial slide 15, capable of longitudinal, frictionally held adjustment; A block 16 rising from the inner portion of each slide forms an elevated seat for a rocking shoe-mount. In the particular construction shown, a shoe-mount saddle 17 rests upon the top of each seat-block 16, with downwardly projecting side wings 18 emtracing the same. The top of the seat and the under surface of the saddle which rests thereon are similarly. and cylindrically curved as indicatedat 19, so that the shoemount is capable of rocking in the vertical radial plane (referring to the circular symmetry of the machine as a whole), the support thus afforded being of reat strength and solidity. A pin 20 passing transversely through a hole in the block 16 and through arcuate slots 21 in the wings 18 prevents displacement of the saddle, and by means of a wing-nut 22 on the pin the saddle can be locked at one or another angular positions if desired, though ordinarily the saddles will be left free to find their own angles when the pressure comes on them. A smooth cylindrical pin 23 projects upward from each saddle to enter a corresponding hole in a last 24 inside each shoe.

A rest 25 for the forward part of the shoe is also mounted upon each slide 15, at the outer end thereof. For convenience these will be termed toe-rests. Each preferably comprises a tube 26 rising from the slide at a slight outward inclination and having a horizontal foot 27 by means of which it is secured to the slide. This foot is slotted at 28, so that the toe-rest can be adjusted horizontally toward and from the shoe-mount proper upon loosening the securing screw 29. V A screw-threaded shank 30 projects upward from the tube and carries a transverse cushioned head 31. The shank passes through a nut 32 resting on the upper end of the tube, turning of this nut causing the head 110 31 to be supported higher or lower, according to requirements. A radial set-screw 33, passing through the wall of the tube and bearing against a fiatted region 3 1 on the side of the screw, prevents the latter and its head 115 from turning.

A superstructure rises from the central part of the table around the projecting por tion of the shaft 8, said superstructure preferably comprising pillars 35 secured to the 120 disk 4; and a hub 36 united to their upper ends and having a bearing opening turning on the shaft. Said hub is formed withradial slots 37, and is split at right angles to its axis, the plane of cleavage passing through the slots. The opposed faces of the halves of the hub have complementary circular grooves 38, and the two halves are united by fastenings 39. The inner ends of radiating heelpresser levers 40 are received tiltably in said levers are widely forked in aform suitable to bear upon the backs of the shoe heels as seen in Fig. 1, such forks being faced with yielding material 43. Said outer ends lie approximately over the shoe-mounts, which are adjustable horizontally, out and in, to secure the proper relation for any particular kind or size of shoe.

Operating connections, in the form of draw-bars 44, extend downward from the heel-pressers to points below the table, where they are adapted for cooperation with pressure-applying means. In the illustrated construction each draw-bar 44 is pivotally connected to its presser-lever intermediate the ends of the latter and passes vertically downward through a hole 45 in the table, inwardly of the corresponding slide 15. On the lower end of each bar is an enlarged head 46. Springs 47 connected to eyes on these heads and to the under part of the table urge the bars and levers 4O upward to raised positions, the limit of which may be determined by stops 48 projecting from the lower parts of the bars.

Each of the bars 44 is longitudinally recess'ed at its inner side to receive a serrated rack-bar 49, held by screws 50. The rack projects from the side of the bar sufliciently to form a key, which slides in a key-way 51 in the side of the hole 45, to keep the drawbar from turning. The teeth of said rack are fine and close together and face upward, and cooperate with similar, downwardly facing teeth on a clutch 52. One of these clutches is provided for each heel-presser, and preferably comprises adog pivoted on a transverse pin 53 in a notch 54 in the outer end of a block 55, which is secured to the inner end of the corresponding arm 5 by the screw 9 and another screw 56. The pivot of the dog is spaced from the rack and its toothed engaging portion is at its lower end, which is pressed against the rack by a spring 57. lVith these relations, the dog permits the bar to descend freely but automatically holds it at any point in the range of the rack against upward movement. The dogs are normally releasable by handles 58 projecting upward therefrom, or other means may be provided for releasing the clutches after the pressure has been held sufficiently long.

A common treadle lever 59 is fulcrumed on the basal portion of the machine, and to it is connected the lower end of an upwardly extending draw-bar 60, which slides in guides 61 on the standard. A spring 62 sustains this bar at a normal position, with the treadle up. The upper end of said bar has a yoke 63, open in its interior and at both sides, and slotted across the top, so as to permit the entrance and withdrawal in lateral directions of the heads 46 of the depending bars 44. Thesocket 64 in the yoke 63 which receives the heads is made sufliciently deep so that the heads may enter whether they are up or down. (See Fig. 3.)

In order to aid in bringing the table to rest at each operating position, after a short partial rotation, the periphery of the disk 4 is formed with notches 65, which receive the nose of a horizontal plunger 66, pressed by a spring 67 inside a housing 68 on a block 69 secured to the top of the standard. This constitutes an impositive holding device which tends to bring the table to rest at each position, while permitting it to be readily turned by the operator.

The operation has already been indicated. The supporting parts are adjusted for the kind and size of shoe to be operated upon. The term shoe is, of course, used generally. Assuming the machine to be empty, the operator takes a shoe with a last therein and its heel stuck on by wet cement, with or without nails or other fastenings, and places the same upside down on the saddle 17, which is in front of him, the toe portion of the shoe extending outward or forward and being propped against the corresponding toe-rest 25. The operator then steps on the treadle, and by virtue of the leverage and the power which it is possible to exert by throwing his weight on that foot, brings the corresponding presser lever 40 down upon the back of the heel with heavy pressure. The shoe-mount rocks to accommodate itself and the shoe to the pressure. The pressure is held automatically by the clutch and the operator at once takes his foot off the treadle. Owing to the fineness and closeness of the teeth of the clutch, the heel-presser is 110 held depressed at any point within the range of the clutch, substantially without any sinkback or relaxation of the pressure when the effort is removed from the treadle. The operator then turns the table a step. This 115 carries away the clamped shoe and brings a fresh position on the table in front of the operator. Another shoe is put on, pressure applied, and the table turned another step.

In this way the table is completely loaded 120 with shoes and their heels held under uniting pressure. lVhen the first shoe comes in front of the operator again it is ready to be taken off. The operator accordingly presses the handle 58 of its clutch, whereupon the 125 springs 47 of this heel-presser raise it out of the way. The operator takes off the finished shoe, puts on a new one and continues as before. As heretofore indicated another attendant may be stationed at another point 130 to take oil and put on the shoes. The fixed holding of the shoes in the machine may also be utilized for performing other operations. Thus, special heel fasteners maybe adjusted or inserted while the shoes remain held and clamped.

WVhile the preferred embodiment has been described in detail, it will be understood that numerous changes may be made without departing from the essential novelty. As far as we are aware this is the first machine for accomplishing its purpose.
