ISLAND SHOE TIP AND HEEL 12R-Essuie MACHINE Application led June 2, 1928. Serial No. 282,296.

Thenvention disclosed herein relates to a shoe tip and heel applying machine.

It has been the practice heretofore in the artin applying a toe cap of rubber to a fabric upper while mounted upon its last, to use a roller which is operated by hand to roll the rubber tip as well as the heel portion of the foxing into intimate contact with the fabric.

. Such a method requires considerable time and skilled labor and does not always produce uniform results.

Itis an object of the invention disclosed herein to provide a machine which simultaneously applies a uniform'pressure to the tip and if desired also to the heel portion of the shoe foxing.

Another object of this invention is to provide means for applying a pneumatic pressure to the tip of the shoe. y

Still another object is to provide a machine which is adjustable so as to receive shoes of different sizes.

Another object of the invention is to provide'a machine which simultaneously brings the tip of the shoe into engagementwith pressure applying means and applies pressure thereto.

Other objects of the invention and results obtained thereby will appear from the detail-ed description which follows In the drawings:

Fig. 1 sho-ws aperspective view of a preferred embodiment of the invention.

Fig. 2 shows a plan view of the device of the invention.

Fig. 3 shows a side elevation of the device, and

Fig. 4 is a cross-sectional view on line 4-4 of Fig. 2. n

The machine has a pedestal 1 which carries base plate 2 suitably mounted thereon. Attached to the base plate 2 in any convenient manner is a pair of boxes 3. Boxes 3 are provided with cavities 4 in which extend diaphragms 5 made of rubber or other suitable material. The edges 6 of the diaphragms 5 are held between the front faces of boxes 3 and clamping plates 7. Clamping plates 7 are attached to the boxes 3 by screws 8.

Clamping plates 7 have slots 9 therein in which move the slidable plates 10. Plates 10 are provided with apertures 11 for receiving the toe of a shoe, which extends into the cavities 4 so as to Contact with the diaphragms 5.

Diaphragme 5 and the cavities 4 together form a closed chamber for receiving fluid under pressure.

A fluid under pressure is supplied to the other end to the pedestal 1. The valve 15 isv supported on the pedestal 1 by the bracket and bolt 21.

The base plate 2 has an extension 22 upon which are mounted slideways 23. The screws 24 serve to hold the slideways in spaced relation on the extension 22. The plates 25 which are attached to the slideways v23 by screws 26 serve to hold the slideways in spaced relation at their upper edge.

A channel 27 is formed by the spaced relation of slideways 23 in which channel slides a bar 28. VThe bar 28 carries at its outer end cross bar 29 to which is attached the curved plates 30 by means of screws 31. On the inner face of curved plates 30 there are pads 32 j agapted to press against the heel portion of a s oe.

In order that the bar 28 may be moved in channel 27, it is provided with a rack 33 which cooperates with pinion 34. The pinion 34 is mounted on one end of the shaft 35 which is journaled in the bracket 36. Adjacent the opposite end of shaft 35 is fixed a disk 37 having holes 38 extending therethrough near its periphery. Juxtaposed to the disk 37 is a lever 39 which is rotatable on the shaft 35. The lever 39 is held on the shaft 35 by collar 40. A pin 41 is carried by the lever 39 and cooperates with the holes 38 in Y disk 37. An aperature 42 isprovided in the lever 39 which receives the end of connecting 1 link 43 which link is attached at its other end to a foot pedal (not shown) Upon operation of the foot pedal the lever 39 is moved downwardly causing the shaft 35 and pinion 34 to rotate thereby moving the bar 28 inwardly. As the bar 39 rotates downwardly, its end 44 cooperates with the end 45 of lever 18 to rotate shaft 1T of the air admittance valve 15. The link 43 and lever 39 are nor maliy held in the position shown in F ig. l by a spring` (not shown) connected with the link 43. The extent of the movement of thc bar 28 and its associated parts can be varied by means of the pin 41 which may be inserted in any of the holes 38 at the choice of the operator.

In the operation of the device a pair of plates 10 are selected to correspond to the width of the toe of the shoe and are inserted inthe slots 9. The toes of the shoes, previously cemented and with toe caps in position are inserted through the apertures 11 and into contact with the diaphragms 5. The pedal of the machine is pressed downwardly thereby causing the bar 28 and the heel pads 32 carried thereby to be brought into contact with the heel portion of the shoe so as to apply pressure to that portion and also to press the toe of the shoe into contact with the saclf. 5. As the lever 39 is rotated downwardly by the motion of the pedal, the lever 18 is caused to rotate thereby operating the valve 15 which admits fluid under vpressure into the cavities 4. This fluid under pressure acts upon the sacks 5 to press the rubber toe cap into close contact with the fabric of the shoe so that the cement provided for adhering the fabric and rubber toe cap may form a secure union. A backwardly thrusting pressure from the diaphragms is transmitted to the resilient heel pads 32 by the shoe and its last. This serves in the same wav to form a secure union between the rubber foxing or heel portion and the fabric of the shoe.

While a preferred embodiment of the invention has been disclosed in detail, it is not intended to limit the invention thereto but only to limit the invention by the scope of the claims hereunto appended.
