' 6 Claims.
The invention relates to improvements in shoe sole-cementing machines, in which is set forth a combination of shoe jack and cement press. 7 The objectsof 'improvement'are, first, to eliminate the necessity of preparing the shoe on a separate jack before it is taken to the cement press, and, sec- 7 end, the use of self-inflating, air-filled, rubber pressure pads, eliminating the necessity of filling pad with water, or of using an air pump.
A pictorial illustration of this invention is found in the accompanying drawing.
A shoe sole-cementing machine comprising a perpendicular shaft I, has a lower end fastened permanently to base 2. On the upper end of shaft l, a T 3 is fastened by means of a set screw 4; a horizontal shaft 5 fits in T 3, held in place by set screw 6. Upon each end of the horizontal shaft 5 is a last holder 1, upon which lasts 8 are held in place by means of bolts 9. Last plates l0 fit on bottom of the lasts 8 and are held in place by means of pins I I fastened securely to last plates l0, said pins ll slip into holes I2 drilled in the lasts 8.
The last holders 1 are held on the ends of the horizontal shaft 5 by means of slots I 3 in the last holder bearings. A pin !4 fits loosely in slot l3 and screws into shaft 5. When shoes are placed upon the lasts 8, lasts 8 and holders 7 are in position A. The heels of last holders 1 rest on a horizontal shaft l5; said shaft l5 fits in a T I6, held in place by a set screw H. T l6 is fastened to the upper end of a perpendicular shaft ill by a set screw I9; the lower end of shaft I8 is fastened permanently to the base 2.
After shoes have been placed upon the lasts 8 and cement has been applied to the bottoms of the shoes and their new soles, the soles are placed upon the bottoms of the shoes and tacked temporarily in place.
The last holders 1 are then swung to position B. The ends of the slots If, in last holders 1 bearings striking pin l4, act as stops and shoes are held directly over the rubber pressure pads 20. The rubber pressure pads 28 rest on a pad holder 21.
The rubber pressure pad 26 has a valve opening (similar to the valve stem used in an inner tube but without an inn r valve and having a rubber-lined valve cap). The valve 26 is located on the rear under-side of press re pad 29 and extends through a hole in pad holder 2|.
The pad holder 2| is bolted to flange 22, said flange being slidable on the perpendicular shaft l.
Pressure is applied to soles by means of a lever 23 being pressed downward, the other end of lever 23 coming in contact with the lower part of flange 22; forcing the fiange 22 upward, and'causing the rubber pressure pads 2|] to press soles firmly against the,bottoms of the shoes. Said lever 23 is pivoted'to base 2' in any convenient manner as indicated in the drawing. The lever 23 is held down by means of a slide bolt 24 being pushed through a hole 25 in the perpendicular shaft 18, and over lever 23.
After the cement has dried thoroughly, the lever 23 is released by pulling back the slide bolt 24. There is now sufficient clearance between the soles of the shoes and the rubber pressure pads 29 to allow the last holders 1 to be swungback into position A.
The temporary tacks are removed while the shoes are still on lasts 8 and, if necessary, a couple of tacks are pounded into the shank of the sole. The shoes are then removed from the lasts and are ready to be trimmed and finished.
I am aware that prior to my invention solecementing machines have been made using air or water filled rubber pressure pads (air being forced into the pads) and used for cementing soles upon shoes after the shoes and soles have been prepared upon a separate jack. I therefore do not claim such features broadly but I claim:
1. A shoe sole-cementing machine having a last holder comprised of an annular bearing, a front leg fastened rigidly thereto, the leg curving downward and terminating in a foot and means provided for fastening the fore part of a plate last thereto, another member fastened rigidly to the bearing and extending backward in line with said bearing toward the heel of the last; said member making a right angle turn downward to form a rear leg to the last holder; said rear leg having a foot similar to the front leg, and means provided for fastening the heel part of the last thereto.
2. A shoe sole-cementing machine having a last holder containing a bearing which fits on the end of a horizontal shaft, said bearing having a slot in the center extending halfway around it, and a pin fitting loosely in the slot; said pin being threaded on one end and screwed into the horizontal shaft which supports the last holder, the pin serving to prevent the last holder from slipping off the horizontal shaft, to hold the toe of the last rigid when pressure is applied to the sole of a shoe, and, when the last holder is turned upon the horizontal shaft, the end of the slot in the bearing comes in contact with the pin, thus preventing the last holder horizontal member parallel to a shaft supporting a plurality of last holders, and an inflated pad' for each last holder, said member being supported by a vertical standard which is fastened to the base of the machine in a position such that when the last holders are turned so that the lasts are no longer over the pads but the bottoms of the lasts are up, the heel part of a last holder rests upon the horizontal member before mentioned.
4. In a shoe sole-cementing machine the combination of a base, a vertical member, the lower end of the said member fastened securely to the said base, a horizontal member fastened securely to the top end of the aforesaid vertical memher, a plurality of last supports mounted on the said horizontal member, a plurality of pads made of resilient flexible material underlying the said last supports, a support for said pads, and means for raising and lowering the said support.
5. In a shoe sole-cementing machine thecombination, of a base, a vertical member fastened securely to said base, a slidable table mounted on the said vertical member, a plurality of hollow air filled rubber pads resting on the said slidable table, means for raising and lowering the said table, a horizontal member fastened to the top of the aforesaid vertical member, a plurality of last supports mounted on the said horizontal member, and a plurality of lasts with means for fastening said lasts to said supports, the said last supports being turnable on the said horizontal member.
6. In a shoe sole-cementing machine, the combination, with a hollow air filled pressure pad of flexible resilient material, of a support for the pad, a shaft on which the said support is mounted, the support being slidable on the said shaft, a base to which the said shaft is securely fastened, a lever pivoted tothe base in a convenient manner for the purpose of sliding the pad support up and down on the said shaft, and suitable means provided for locking the said lever down.
