Application filed November This invention relatestomachines for ironwhich extend toward each other beyond the \55 ing the toes of shoes, and an object of the invention is to provide a machine for use in the manufacture of shoes, whereby the folded edges of the shoe parts may be smoothly pressed and adhesively united with greater ea'se,'rapidity and "less cost than by present practices. I i

Another object of the invention is to provide a machine for ironing, smoothing and pressing the in-folded lower edges of the shoeuppers to formsmoothsurfaces so that, 1 when the shoe is'c'ompleted by the attachment of the sole, no grooves,.openings orinterstices ment ofthis result, provisionis made forfthe adjustment of the machine for work upon shoes of different sizes.

Various other obj ects of the invention will appear from the following description, refer- 'ence being made to the drawings, in which Fig. 1 is a front elevation of my improved machine. Fig. 2 is a side elevation.

Two of the crossangle bars 2 are connected by an intermediate angle bar 3, the horizontal flange of which constitutes a guide for parts of the machinem A table to 4 is .attached upper seriesof'cross 'ars 2.

The machine shown is designed and adapt ed for operation upon both shoes of pairs of shoes and comprises supports for the right and left shoes respectively. The support for each shoe comprises a'body 5 having at its front end of .a pair of spaced standards 6 and at its rear end a slot .7. from each side of which rises a vflange 8, the inneredgesof to the sHoE-ronmonme- MACHINE.

inner walls of the slot 7 so that the space between theinner edges of theflanges 8 is of narrower width than the'width of the slot 7 (Fig. 5). A bolt 9 extends through the slot 7 and through a hole in the frame top 4 and with the nut 10 constitutes a clamp for securingand' holding the part 5 in rigid position andpermits the art 5 to be secured-in selected adjustmen s. as required to accommodate shoes ofidiiferent sizes. 4 A block 11- has a pair of laterally projecting trunnions 1 2 seated in. notches in the standards 6 and a gripper-or friction block" 13 (Flg. 4) in each of said notches presses upon thetrunnion 12 therein. A spring .plate 14 ateach side of the block 12 seats upon the upwardly extended end of the correspondingblock 13 and, by means ofpre'ssure applied thereto byscrews 15, causes the block \13 to bear with the desired pressure upon the trunnion 12 in order to hold the block -11 in its selected adjustments. That is, the upper endof the block 11 may be swung forwardly or rearwardly to a desired adjustment and retained in such adjustment by Ipressureof the blocks 13 upon the trunnions12, but will per- ,mitthe block 11'to be forced from one adjust ment to another. A spindle 16 is screwed in.

" the upperend of each of the. blocks 11and the length of each of said spindles above the corresponding block 11 may be varied as re-" quired to accommodate the machine for work upon shoes of'different sizes. That is, for a work upon shoesof small sizes, the spindles 16 will be adjusted to extend a greater distance above the blocks 11 than for work upon shoes of large sizes. i A gage orclamping nut 17 is threaded upon-eachof the spindles 16 and may be turned thereon to the pofition desired -to obtain the desired adjustment of the spindle 16 and to prevent accidental turning of said spindle.

' the course of manufacture is mounted for operation of this machine.- As there shown, the

Fig. 2 showsthe mannerin which a shoeiil shoe 18 ison its last 19. the rear end of which ing block in proper adjustment.

1 this, a will be seen that theshoe "is placed.

upon the support upside down, the toe extending rearwardly.

The support for the toe comprises a block 20 extending between said flanges 8 and having a depending flange 21. A clampin'g boltper end of the toe supporting block 20 is provided with a head 25 which is appropriately dished to receive and support the toes of shoes having lasts therein. In use. the head 25 is preferably covered with a piece of chamois 26 or other appropriate material to prevent damage to the shoe when the machine is operated.

Each iron 27 is supported by a vertically movable frame. Each frame comprises a pair of rods 28, a cross head 29 connecting said rods at their upper ends, and a cross head 30 connectingthe lower ends of said rods. The rods extend for sliding movements through the top 4 and the cross bars 3 are guided thereby.

supported by eachframe by means of a hanger 31 having pivotal connection 32- with the structure of the iron so as to permit such movement of the iron as may be necessary for it to'press with equal pressure across the entire portion of the shoe upon which it is intended to operate. Each iron is provided with an electric heater 33 of known construction connected with circuit wires 34 by which the current is supplied, the current being controlled by any desired switch connections (not shown) Each rod 28 is encircled by a coiled spring 35. These springs 35 have their lowerends bearing upon the cross bar 3 and their upper ends againstcollars 36 rigid on the rods'28, and thereby serves to support the iron frames 1n their highest elevation and to raise such frames after each operation. Extent of upward movement of the iron frames. by the springs 35 is limited by collars 37 on the rods 28 arranged to abut against the undersurface ofthe top 4. I

Each iron frame has operating connections.

. As shown, the operating connection for each frame comprises a'link 38 extending downwar'dly from connection with the lower cross head 30 to connection with the cylinder 39.

Each cylinder 39 encloses a spring- 40. A rod 41 extends into each cylinder 39 through the. spring 40.there1n. .A pin 42 in connection with the upper end of each of the rods 40 its.

One of the irons-27 is' constitutes an abutment for the upper end of the spring 40 and extends through slots 43 in the cylinder 39, thuspermitting expansion and contractionof the spring 40 within linino openings between the parts of'the shoe.

The frontend of each of the treadle levers 44 operates with-in; a guide 46 provided with latchte'eth 47 for engagement with a part 48 on the lever 44. to hold the lever 44 down so long as desired.

The lower end of the rod 40 is'connect-.

The lever 44 is capable of suflicient lateral oscillation to efi'ectengage' ment and disengagement thereof with respect to the latch teeth 47 In operation, the shoe is applied as shown 4 (Fig. 2) and as herein described with the last upon the'spindle 16and the toe of the shoe resting upon the non-abrasive cover 26 in order-t0 present the bottom of the shoe having the creased folded edges toward the iron 27. Then, .the treadle 44 is operated to press the iron with the desired degree of pressure against that part of the shoe presented for operation of the iron thereon with the result that the parts are smoothed and the adhesive substance is caused to form a smooth surface so that, when the shoe is finishe'd, the parts present smooth sui faces against each other. The machine is capable of easy and rapid operation and may beconstructed economic-ally. The construction and relationship of the cooperative elements of the machine may be varied within equivalent limits without departure from the nature and principle of the invention.
