2 Claims. (Cl. 12-125) This invention relates to shoe machinery, and more particularly to a method of and apparatus for maintaining heels against the shoes while the glue or cement sets or dries during the manufacture of the shoes.

The object of the invention is to provide a method of and apparatus for maintaining heels on shoes under pressure, the present invention being automatic and under the ready control of an operator.

Another object of the invention is to provide a shoe heeling machine wherein the shoe is supported in an immobile position while pressure is applied to the heel during the process of permitting the glue or cement to harden or set, the present invention permitting the heels to be applied uniformly and accurately to shoes of various sizes and shapes.

A further object of the invention is to provide a heeling machine for shoes which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application and in which like numerals are used to designate like parts throughout the same:

Figure 7 is a view showing the heel holder or clamp.

Figure 8 is a fragmentary sectional view showing certain constructional details of the machine.

Referring in detail to the drawings, the numeral 10 designates a frame which may be made of any suitable material such as angle iron. The frame 10 includes vertically disposed spaced

parallel legs

11, 12, 14 and 15. The lower ends of the legs may be secured to a suitable supporting structure such as a floor by suitable bolts or screws 13, Figure l. Interconnecting the

legs

11 and 14 together and secured thereto is a crosspiece 16, and horizontally disposed channels 17 and 18 secure the front and rear legs together adjacent their tops, Figure 3. Horizontally disposed spaced parallel bars or

beams

19 and 20 are arranged below the channels 17 and 18.

Spaced from the frame is a base 21 which supports a motor 22 that is adapted to be connected to a suitable source of electrical energy. A pulley 23 is operated by the motor 22, and an endless belt 24 is trained over the pulley 23, the belt 24 also being trained over a pulley 25 that is mounted on a drive shaft 28. The drive shaft 28 may be supported by the

bars

19 and 20, and a clutch including clutch parts 26 and 27 is provided for controlling rotation of the shaft 28 by the belt 24. For controlling the clutch, a lever 29 is provided with a foot treadle 30 on one end thereof, and the other end of the lever 29 is pivotally connected to the leg 11 by a pin 32. A rod 33 extends upwardly from the lever 29, and a spring mechanism 34 is mounted on the upper portion of the rod assembly 33. A link 35 extends from the rod assembly 33 to a yoke 36 which is connected to the clutch part 27. A

"ice

spring 31 is connected to the lever 29 for normally maintaining the lever 29 in raised position. Thus, by applying pressure on the treadle 30 with the operators foot, the rod assembly 33 will be lowered whereby the clutch part 27 will be moved into engagement with the clutch part 26 so as to cause the motor 22 to impart rotation to the drive shaft 28. Then, when foot pressure is released on the treadle 30 rotation of the shaft 28 will stop since the clutch parts 26 and 27 will become disengaged as shown in Figure 3.

Supported above the bar 20 is a driven shaft 37, and a gear 38 is mounted on an end of the shaft 37. The gear 38 meshes with a gear 39 that is mounted on an end of the drive shaft 28, and a worm 40 is mounted on the driven shaft 37 intermediate its ends. A gear wheel 42 is arranged in meshing engagement with the worm 40, and the gear wheel 42 is mounted on a stub shaft 41.

A release means is provided for at times manually releasing the pressure on the shoe heel, and this release mechanism includes a crank 43 which is connected to an end of the stub shaft 41. The gear wheel 42 is mounted for rotation about the shaft 41 and the driven half of the clutch 45 is keyed to the shaft 41 so that power can rotate the shaft 41 clockwise (Figure l) to apply pressure on the shoe heel and still permit counter-clockwise rotation of the shaft to release the pressure since the gear wheel cannot be rotated counter-clockwise. A clutch 45 is provided, and the clutch 45 and gear wheel 42 have coacting teeth 44, Figure 3. A yoke 46 is arranged in engagement with the clutch 45-for shifting the clutch along the stub shaft 41, and a handle 47 is provided for actuating the yoke 46. A pin 48 pivotally connects the handle 47 to a bracket 49, Figure 2. The teeth 44 may be arranged on the clutch 45, and similar teeth may be arranged on the gear wheel 42 so that by shifting the clutch 45 by means of the handle 47, these teeth can be arranged in engagement with each other whereby the clutch 45 which is keyed to the shaft 41 will cause the gear wheel 42 and the shaft 41 to rotate in unison when the crank 43 is turned in order to apply pressure on the shoe heel. When the clutch 45 is engaged, power from the motor will cause rotation of the shaft 41, the worm gear 42 and the crank 43 clockwise (Figure l) to apply pressure to the heel and when the clutch is disengaged the crank may be rotated counter-clockwise to release the pressure.

There is further provided a standard 50 which has its lower end pivoted to the frame by a pin 52, and the standard 50 includes a lower hollow tube 51 that is threaded interiorly. A post 53 has a threaded portion engaging the tube 51, and a nut 54 is provided whereby the effective height or length of the standard 50 can be varied as desired. A support member 55 is secured to the upper end of the post 53, and the support member 55 provides a support for a shoe 56 to which a heel 57 is to be applied.

A clip 58 is secured to a suitable part of the frame, and a chain 59 is connected to the clip 58. The other end of the chain 59 is secured to an arm 60 which forms part of a body member, and the arm 60 has one end connected to a bushing 61. Also connected to the bushing 61 and arranged angularly with respect to the arm 60 is an arm or rod 62 and a threaded bolt 63. The arm 62 may be pivotally connected to the frame by a pin 70. A turnbuckle 64 interconnects the bolt 63 with a second bolt 65, and a pin 66 connects the bolt 65 to a lever 67 which is pivotally mounted between ears 69 by means of a pin 68.

A ring member 71 is pivotally connected to the upper supporting portion 55 of the post, and the ring member 71 is pivotally mounted by means of a pin 72 that has a spring 73 circumposed thereon, Figure 5. The ring member 71 is provided with a cutout 74 for snugly receiving therein the heel seat of the shoe being applied. For gripping the heel 57, a clamp 75 is provided, Figure 7, and the clamp 75 includes a pair of pivotally mounted arms 76 and 77. A spring 78 interconnects the rear portions of the arms 76 and 77 together, and an adjustable bolt 79 also extends between the ends of the arms. By manually rotating the bolt 79 the relative position between the arms 76 and 77 can be varied so that the clamp can be adjusted to accommodate different sizes of heels. Suitable screws 81 may be provided for pivotally connecting the arms to a pressure plate 80.

Pivotally connected to the top of the pressure plate 80 is a strip 83, the strip or member 83 being pivotally connected to the plate 80 by a bolt and nut assembly 82. Figure 6. A pair of spaced parallel apertured ears 84 extend upwardly from the member 83 and are secured thereto or formed integral therewith, and the ears 84 receive therebetween the front end of the bar or lever 67. A pivot pin 85 extends through suitable registering apertures in the cars 84 and member 67. A pair of leveling screws 86 and 87 extend through portions of the member 67 and into engagement with the member 83 so that by adjusting the leveling screws 86 and 87 the angular position of the member 83 can be varied as desired.

From the foregoing it will be seen that a heel may be glued or cemented to a shoe such as the shoe 56. In use the motor 22 is adapted to be connected to a suitable source of electrical energy and then by applying pressure to the foot pedal or treadle 30, the rod assembly 33 will be moved downwardly to thereby cause the clutch part 27 to engage with the clutch part 26 whereby the shaft 28 will be rotated by the belt and pulley driven by the motor 22. Rotation of the shaft 28 rotates the worm 40 and this in turn rotates the gear wheel 42 which is mounted on the shaft 41. By moving the clutch 45 by means of the handle 47, the gear wheel 42 can be caused to rotate the shaft 41 so that a crank 88 can be moved a desired distance. The crank 88 is connected to the shaft 41, and the crank 88 is connected to an end of the arm 60 by a pin 89, Figures 1 and 3. As the crank 88 is moved there will be movement of the

arms

60 and 62 and also the rods 63 and 65 will move so that the lever 67 will pivot about the pin 68. This pivotal movement of the lever 68 is transmitted to the member 83 and to the pressure plate 80 so that the heel 57 will be maintained under pressure on the shoe 56 until the glue or cement hardens. The shoe heel can be readily clamped in place by means of the arms 76 and 77 which form part of the clamp 75. The pivotal connection 52 permits the stand ard 50 to be swung outwardly when a shoe such as the shoe 56 is to be placed thereon. Further, the ring member 71 can be pivoted about the pin 72 so as to permit the cutout 74 to be moved into and out of engagement with the rear edge of the shoe heel. When pressure of the plate 80 is to be released on the shoe heel, the crank 43 can be rotated in order to rotate the shaft 41 whereby the crank 88 will be moved so as to cause the arms and lever 67 to move and release pressure on the plate 80.

The present invention is especially suitable for use with shoes in which the heel is attached by cement or paste. The chain 59 pulls the standard 50 into place when the crank 88 is moved. By means of the set screws 86 and 87, the plate 83 and plate 80 can be tilted so that more or less pressure can be applied to the rear or front of the heel. With the present invention pressure is applied gradually and any chance of an air pocket forming between the heel and shoe is eliminated. The pressure is applied by a squeezing action instead of a striking blow and it will be seen that there has been provided a method of heeling a shoe in an outside heel seat ring rather than applying pressure on the inside of the shoe through the insole as has been done with previous machines. The ring member 71 has the cutout 74 for snugly receiving therein the heel seat of the shoe when the heel is being applied, and the clamp holds the heel.
