` SOLE-LAYING MA'oHiNE.

Application led January 26, 1922. Serial No. 531,879.

. rI`his invention .relates to machines for operating upon boots-and shoes and is herein illustrated as embodied in a machine for laying unvulcanized soles of rubber, rubberized pressing members-.to move inwardly or similar material upon the bottomsof shoes. l

' In laying'an unvulcanized rubber sole it is usuallydesirablenot only to press the sole firmly againstf the bottomof the shoe,

but also to bend the margin. of the sole up wardly and to press it against the lower portions of the sidesl of theshoe. 'In somei rubber-soled footwear, such `as sneakers, the

upward-bending of the margin of the sole is comparatively slight; but in other types, `such as arctics, the sole is sometimes rolled up around the"sidesV of the shoe for half an inch or more. I

The general object of the present inven-' tion isto protvide a machine for laying all 4kinds Ofrubber or similar soles and partie-- ularly` for layingA rolled-edge soles, 'in the process of which pressure is app-lied both in a direction substantially perpendicular -to thebottom of the shoe and in a direction' substantially perpendicular to the sides of the shoe. i

According to one feature of the present inyention, there are provided a bottompressing' member-or membersand side pressing members together with meansfor causing the bottom-pressing member to press ythe sole against the bottom of the shoe and the d an pressagainst 'the lsides of the shoe'. -Con- ',veniently the machine may comprise a support for a lasted shoe. a box-like structure adapted to receive a shoe and having movable sides, means for causing relative movement of approach between the support and the box to cause'the shoe to enter the box, and means forthen moving the sides of the box inwardly j'so as'to cause them to close about the shoe. With. such a construction the body of the sole is pressed firmly against 4the bottom of the shoe and the sides of the .box move inwardly to press the upturned l margin ofthe sole against the lower portions of thesides of thefshoe.

These and other features of the invention including 'certaiil details of construction and combinations'of parts will be described as embodied. in an illustrative machine and pointed out in the` appendedfclaims.

A Referring to the accompanying drawings, 'Fig'. 1 1s a cross section through the forepart of a lasted shoe with an uncured rubber cole adhering to its bottom and ready "to be' partly in elevation, showing armachine, in

which` the present invention. is embodied with a shoe and its sole in .the positions which theyl occupy just prior to .thelsole laying operation.' The sole shown in this .figure is of a somewhat different shape from that shown in Figs. l and 2, and has a prof. jecting flange which is designed to be turned up and pressed against the lower portion of the sides of the shoe.

Fig. 4 is a view, principally in cross sec# tion, of the same machine and shoe which `are shown in Fig. 3, but with the parts in the positions whichthey occupy at the completion of the sole laying operation.

Fig. 5 is a cross-section of the machine on the line 5--5 of Fig. 3, a portion of the rubber 'blankets which cover the opening in the box having been broken away. Fig. 6..is a vertical longitudinal. cross sectilpn through the lower portion of the `ma c me.

Fig. 7 isaV view, partly in section'and.

-partly in side` elevation of as portion of a machine embodying a modified form of the invention. i I

Fig. 8 is a plan of the parts which are shown in Fig. 7. c .f

.Fig. 9 is a vertical cross section of the machine shown in Fig. 7 with the arts in the .ositions which the occupy att e comi.

pletion of the sole vaying operation, a-

lasted shoe.` being shown with its lower portion extending into the box, and

Fig..l0 is a cross section, similar to Fig.

9,' but showing the parts of the machinein Referring rst to Figs. 1 and 2, there is shown in -Fi-g. ly a lasted shoe having adhering to its bottom an unvulcanized rubtheir normal ositions. 'f'

ber sole of the s o-called roll-edge i type. n Fig. 2 this sole is shown inthe position. which vit occupiesafter it has been laid. It will be noted that the main portion ofthe sole has .been pressed rmly against tra that the bottom oit the shoe and that 'the margin oit the sole has been bent upwardly and pressed against the lower portions ot the sides ot the slice. 'lhe sole 200 shown in Figs. 3 and et has a ilange extending outwardly trom a portion ot' its edge; and in the laying ci this sole, this Flange should be bent upwardly and pressed against the lower portions of the sides oit the shoe. ldlhile therefore, the two soles which have been illustrated 'are et a somewhat different construction, they require practically the same treatment injorder to be laid properly.

ln lthe illustrated machine, the shoe is forced into a box-like structure, which, tor convenience7 will bereierred to merely as the boni. The lower portion oit the shoe is tirst moved into the box whereby the projecting margin ot the sole is bent upwardly; and then the soleA is pressed against the bottom ot the box, and the sides ot the boa are caused to move inwardly so as to press the upturned margin et the sole against the sides ot' the shoe. ln the machine shown in Figs. 3'to 6 inclusive. the carrier tor the box is indicated at 13. This carrier is movable up and down, being guided in its movement by rods 15, and any suitable mechanism may be employed for moving it up to apply the sole laying pressure and for drawing it down after the sole has been laid, the duration of the application of pressure being very short owing to the nature of unvulcanized rubber. A lasted shoe is indicated at 17; and the last isisupported against th sole laying pressure in the usual manner by a heel post and a toe ost,`the latter being indicated at 21. The eel post is provided with the usual last pin whichfis received in the usual socket in the last. 21 is provided with'a toe rest in the form of` a rollb 23 composed of suitable resilient materiabsuch as rubber. The heel post and toe post are adjustably mounted upon an adjustable head 25; the latter being arranged to be adjusted up and down on the guide rods l5. The head is bored and tapped for the reception of adjusting screws 27 which are rotatably. mounted in but held :trom longitudinal movement with respect to a stationary head 29. The adjusting screws have bevel gears at their upper yends which mesh respectively with bevel gears upon. a horizontal rotary shaft 31, said shaft having t handle 33 by which it may be turned to raise and lower the adjustable head E25 and consequently the lasted shoe. .The heel post and toe post are adjustable toward and from each other along a ledge formed on the head 25. The machine as thus far described, except the construction of the box,

'of a: shoe.

The toe post ing in the rubber member 51.

anism :lier causing thecarrier 13 to be raised and lowered has not been shown since any suitable mechanism may be employed which will act rapidly so as not to prolong the pressure upon the uncured rubber sole. Con veniently toggle levers, one of which shown as 2G, may be employed.

lifiounted upon the carrier 13 is a trame 35 which carries the parts ot the collapsible box. rlhis box comprises a bottoni which is movable up and down, andsides which are movable inwardly and outwardly. ln the illustrated machine, there are six ot' these side members, two at each side and one at each end. lThe bottom member comprises a plate 3? tast te the upper end ot a plunger 39, said plunger being slidable in a ver tical bore formed in the trame and being prevented from rotating by means oli' a key l1 (Fig. (i). Mounted upon the plate 37 isa thick piece et" rubber a3. Each side member. is in the Jform of a lever l5 pivoted at l? te the frame 35 and having an inof movement et the plate 37 so that when a shoe 'is forced into the box and thereby pushes the plate 37 downwardly, the sides of the box will be rocked about their pivots et? into the positions shown in Fig. Il.' rlfhe levers l5 are formed with rectangular grooves and inthese grooves is held a continuous thick piece of rubber 51. It will be noted by referring to F ig. 5 that the rubber is so shaped that it encloses a substantially sole-shaped opening the contour ot which corresponds to that of the lower part This endless piece of rubber possesses sultieient elasticity to return the sides of the box from the positionswhich they occupy in'Fig. 4 to their'normal positions .l0 may also be employed. Extending over the opening in the box is a resilient member herein shown as two thick sheets of rubber 53.

In the, operation of this machine. a lasted shoe with an uncured sole adhering to its bottom is placed in position on the jack, and then the carrier 13 is caused to make a rapid reciproeation. As the shoe moves into the box the margin ofthe sole is bent upwardly .by reason of the sole-shaped open- Presently the sole encounters the movable bottom or seat and presses it downwardly. The downward movement of' the bottom rocks the sidesot the box inwardly and causes them to collapse in a direction to press the upturned margin of the sole against the sides of the shoe. It will befnote-d by referring toV Fig. 4 that the pressure exerted by collapsing the sides of the box is proportional to the pressure against the bottom of the sole so that the more pressure applied to thebottom lof the sole, the more is applied to the upturned margin. 'In the illustrated machine, the bottom of the box has been utilized to serve as an actuating memberY for the collapsible sides, not essential that the bottom lof .theA box or any part of it should serve as such4 actating member. y

Referring now more particularlyL to Figs. 7 to 10, the machine, except for the construction of the box, is practically the same as that which has just been'described. In

the machine shown in these figures, the car-` rier 61, which is slidable on the rods 15, is shaped somewhat di'erentl so as to receive a differentlyv shaped rame 63. This frame lprovides a vertical guideway in which the bottom 65 of the lbox is slidablef said bottom being supported by coiled ,springs 67.which at their upper ends encircle guide pins 68 formed on the bottom of the box and -at their` lower ends encircle similar pins 70 formed" on the frame f63.

The collapsible sidesn 72 of the box are each pivotedA at 69 to the'frame, and each has an inwardly extending arm carrying at its extremityK a roll 71 which co-operates with van inclined face 73 formed on the bottom i 65. As shown .best in Fig. 8, the sides ,of

the`box comprise six members or sections .72 two on each side of the box and one on each end; and the inner faces of these members have a combined contour which lis substantially sole shaped. Faste'ncd to the inner faces of the side members is an endless strip of rubber75; and'fast to the top of the bottom member 65 is an elastic strip 77. The box in this case is shown as practically filled with small pieces of rubber 79, these pieces of: rubber serving as a cushion and taking theplace ofthe single thick piece of rubber 43 Awshown in the machine .of Figs. 1' to 7 .i -Stretched across the opening of the Ybox is a series-of rubber cords 81 the opposite ends of whichI are firmly held in clamps 83.

` The mode of operation of this modified machineis similar to that of the `one which was first described. The carrier 61 is moved upwardly to cause the shoe to enter the box. {As the shoe enters they box, the margin of the sole is bent upwardly; and then as the shoe moves farther int t e box, the bottonr is depressed against the springs 67 andthe sides of the box are rocked about their pivots 69 so as to exert pressure against the upwardly bent mar in of the sole. The series of cords' 81, 1i e the .sheets 53 of the machine which was first described, orm a resilient cover for the box. Their purpose, like that of the sheets,`is vto insure thatthe margin of the-so1e shall be wiped upwardly andi that there shall be but it should be understood that it is pressure all` along the lower portions of they sides of the shoe. It is of course impractical to make the sole-shaped opening in theJ top of the box correspond exactly to the outline of the bottom of each shoe. The

yrubber cords shown in Figs. 7 to 10 and the` rubber sheets shown in the machine in Figs. 1 to 6 are resilient and deformable and. consequently tend to make up for the difference between the youtline vof the opening in the top of the box and the outline of the bottom of the shoe. It should be understood, however, that 'the sheets or cords are not essential in the broader aspects of the invention.

Although the invention has been described as embodied in a particular machine in which the side-pressing members are connected with and operated by the bottom-pressing member, it should be understoodthat the invention is not limited in the scope of its application to the particular nmachine which has been shown and described.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is Y 1. A machine for-laying an unvulcanized rubber sole on the bottom Iof a lasted shoe, having, in combination, a resilient member for pressing the sole against the bottom of the shoe, resilient members for pressing the upturned margin of the sole against the sides of the shoe, means for causing the sole to be forced against the bottom-pressing member, and means for moving the -sidey pressing members toward the shoe.
