ST. LOUIS, MISSOURI, TRUSTEES.

SHOE SHAPER.

Application filed December 9, 1925.

Our invention relates to the general class of shoe shapers and particularly to shoe shapers for shaping shoe uppers and smooth ing the backs and sides.

It is the object of our invention to provide in'iprovements in shoe shapers and to conform and modify shoe pressers of the type. described in the United States patent to Rufl' and Ekins, 3:13:34,968, to which reference isv hereby made, in order to provide machines adapted to accomplish new and useful purposes in shoe shaping. We further provide, in the novel modification of the invention re terred to, a plurality of forms and shaping members on a rotatable head which enables the shaping of shoes in a novel and eflicient manner.

In our improved mechanism by the provision of a plurality of shaping forms within which heating units are disposed the uppers may remain within the shaping mechanism a more evenly regulated time than with the use of single pressers. This enables operation with accurately controlled temperature and pressure which eliminates the possibility of ruining the tine leather of shoe uppers by too great exposure to heat or pressure in the shaping operation.

lVe provide a turretor rotatable head adapted to carry a series of complementary shaping forms which move in unison so that to an operator the movement of one unit out of accessible position brings the neXt unit into operating position, so that the position of the operator in placing shoes on the forms need not be changed. and much labor is saved over that required to feed a plurality of individual pressers having no co-operating relatiou.

It is our object in our improved structure to install the electric control mechanism within easy reach of the operator and to so dispose all the connecting parts that there will be little likelihood of damage being done to the clectnical connections inadvertently.

It is further our object. to provide a vertical adjustment for the assembled turret which may be readily adjusted to accommodate the height of an operator without any changes being required in either the electrical connections or the shaping mechanism.

The electrical mechanism is preferably pro- Serial No. 74,404.

vided with a single rheostat which remains stationary but which is connected by means of push pin sockets to stationary brushes which are in contact with rings through which electrical current passes to the individual heating units in the shaping forms. This construction makes a standard head available for any desired number of shaping units without additional changes in structure.

It is a specific object of our invention to provide improved means for shaping shoe uppers on forms comprising rotating elements which apply pressure to shoe uppers mounted on forms with a constant force applied during a complete cycle of rotation of the turret head of the machine. It is also an object to provide the rotating elements with a very effective lock on displacement during the cycle of revolution. Inasmuch as the, structure herein described may be used for pressing complete shoes and unassembled portions of shoes we have in the ensuing claims, employed the term shoe element to include both classes.

An important object of our invention is the application and regulation of suflicient pressure along the sides of shoe uppers, particularly. which will effect a permanent shape. Farther in our novel shoe forms it is our object to provide a structure which may be selectively heated so that some parts of the form will be hot and some parts unheated or some parts will be heated to a greater degree than others.

The aforementioned objects including other specific improvements in the forms and the' means of shaping shoe leather thereon are accomplished by that construction hereinafter described.

Referring to the drawings:

Figure 1 is a side elevation partly in section showing the complete assembly with only one of the pressing heads shown.

Figure 2 is a top plan View of the assembly shown in Figure 1 with one of the pressing heads indicated in detail.

Figure 3 is an enlarged side elevation of the arm carrying the pressing strap with the details of construction more clearly shown H than in Figure 1.

Figure 4.- is a sectional view of the portion of the head consisting of the. parts for supplying the rotating heating units with current v from the stationary rheostat controlled electrical supply lines. H

Figure 5 is a detail elevation of the outer shaping strap showing the preferred arrangement of parts on a tension arm for supporting the strap.

Figure 6 is a side elevation of the preferred type of clamping strap.

Figure 7 is a vertical sectional view of the strap shown in Figure 6 as indicated by the lines 7-7. I

Figure 8 illustrates in side elevation, a preferred type of shoe form.

Figure 9 is a horizontal section of the upper portion of the form shown in Figure 8 as indicated by the lines 99.

Figure 10 is a side elevation of'a modified form of central rod.

Generally indicated at 1 is a split hollow column having an enlarged base (not shown) for resting on the floor in which the sleeve 2 carrying the rotating parts of the machine ismounte The sleeve 2 is vertically adjustable by means of loosening and tightening the bolts 3 which clamp together the split sides of the column. A peripheral flange 4 extending from the sleeve forms the bearing on which the body 5 of the turret head rotates.

We have further provided gibs 6 which prevent upward movement of the body of the turret head and form a convenient means of adjusting the sleeve to a desired vertical position with the elevation of the turret head.

Mounted at the sides of the turret head are the shoe forms 7, a preferred type of which is illustrated and in which electrical heating units 8 are mounted. In the illustration we have shown a turret head with four shaping units mounted thereon but as noted the number of heads mounted is merely a matter of choice andany desired number may be mounted on the turret head in the obvious manner.

We have shown the rods 9 secured to the back part of the shaper forms. These rods are preferably of heat insulated material and they play an important part in controlling the clearance of the shaping means during the intervals of ap lying the work, and the correct seating o the shaping means during the periods of operation. As indicated we prefer to utilize shaping st'raps to shape the shoe leathers against the forms, although we do not limit ourselves to this construction and any means which presses the back and the sides of the shoe against the forms is well within the range of mechanical equivalency.

In slots 10 extending across narrowed portions formed in the lower outer periphery of the turret heads bolts 11 adjustably mount strap bracket arms 12 with a key 13 in a keyway 14 in the turret head permitting adjustment at a desired position on the machined surface of the turret head on which the arm At the lower extremity of each of the arms 12 a boss is formed which is bored as indicated to mount the shaft 15 which may be suitably retained in the bored aperture with a set screw 16. The shaft 15 carries a pressure arm 17 which straddles the boss and journals on the shaft. The pressure applying lever 18 is also journaled on the shaft at one side of the arm 17 and held in position by a collar 19 secured on the shaft 15 by a set screw 20. The arms 17 and 18 both being loose on the shaft a hinged bolt 21 secured on the arm 18 with a pivot pin 22, forms a connecting member between them. A compression spring 23 is mounted on the bolt 21 and the end of the bolt opposite the pivoted end, passes through a slot 24 in the arm 17. A collar 25 on the end of the bolt forms a means of adjusting the spring to any desired tension so that the two arms are connected together with'a spring cushioned oint. The arm 17 has an extension 25 which carries a strap indicated at 26 in Figure 5 by means of the strap clamp 27 which retains the end of the strap and is journaled pivotally at the end of the arm 17 on a pin 28. An adjustment bolt 29 bearing against the outer end of the clamp 27 forms an adjustable means of retaining the strap clamp, and the strap also at-a desired angle with relation to the arm 17. As the arm 17 pivots into position with the portion 26* of the strap extending about the shoe form 7 the adjustment of the bolt 29 controls the position of the strap 26 with relation to the form 7. A compression spring'30 mounted in a depressed portion 31 of the arm 17 bears against the end of the clamp 27 opposite to that engaged by the adjustment bolt 29 and holds the end of the clamp against the bolt 29. The means of mounting the pressure strap is such that the strap first extends to an outer limit with relation to-the form and then the spring 30 allows the strap to fit snuglv over the work mounted on the form.

y The arm 12 has an extension illustrated in Figure 3 carrying the hardened are 32 which is rectangular in section with a machined upper and lower face. A locking bar 33 having bear against the hardened are 32. A releasing lever 36 mounted on a pin 37 in the arm 18 has a bearing lug 38 which with the movement of the lever 36 abuts the side of the lock bar and rocks the lock bar so that the friction pins 35 will clear the arc and allow the arm 18 to be moved to desired position. Excep'ting during 7 periods of pressure on the releasing lever 36 the lock bar is pressed toward locking position by a spring 39 extending from a, boss 40 on the arm 18 and which preferably extends into an aperture 41 in the lock bar which forms a seat for the end of the spring.

The arm 12 has an extension 42 which is engaged by a spring clip 43 extending from the arm 18 which holds'the pressure applying arm in disengaged position while work is being placed on the forms. The operation of the pressure applying arm is, because of the above noted structures, very simple. When it is desired to press the upper of a shoe the shoe is placed on one of the forms. The strap 26* is meanwhile held out of position bythe spring clip 43 engaging the extension 42. By pulling down the end of the arm 18 the strap may be tensioned to any desired degree and during the rotation of the turret head the locking bar 33 provides a means of holding whatever prcssure has been applied to the pressure strap without slippage. Upon the presser head completing a cycle of rotation the pressure strap is released by pressure on the releasing lever 36 which has a handle 44 disposed within a channel 45 in the arm 18 so that the releasing lever and the end of the arm 18 may be moved simultaneously with the fingers gripping the handle 44 of the releasing lever and the end of the arm 18 with the same movement.

In order to provide a convenient means for halting the rotation of the pressing units conveniently to an operator the sleeve 2 has a series of V-shaped grooves 46, illustrated in Figure 4, into which locating plug 47 mounted in a sleeve. 48 in the turret head and eompressed inwardly with a spring 49 seats at intervals in the rotation of the head. A click denotes that the locating plug is seated and the operator then places the work on the form. By a slight pressure the locating pin moves up the beveled edges of the groove and another unit revolution may be made by a manual push on the handle at the end of the arm 18.

The heating units 8 are preferably connected with the lead wires 50 covered with insulating beads in a split bushing 51 which retains the connector member 51 Retained in the turret head are two rings 52 insulated from each other by fiber discs 52 to which the lead wires are connected. At the top of the sleeve 2 insulated on a fiber disc 53 the electrical distributing head is disposed. The head has bolts 54 which extend through the head and the nuts 55 on these bolts serve to retain a pedestal base of the rheostat column 56. F iber washers may be utilized to form a perfect- 1y insulated mounting plate between the distributing head and the base of the rheostat column. In the distributing head electrical contact brushes 57 are connected with lead wire push pin terminals 58 over which the 'emale couplings on the wires-from the rheostat may be easily inserted. The electrical contact brushes are disposed one about the other so that during the rotation of the turret head each brush contacts with one of the rings 52 so that current may be continuously applied from the rings to any number of pressing units. There is no variation in the alignment of the brushes and the rings with vertical adjustment of the sleeve 3 as both the rotating rings and the stationary brushes are mounted on the sleeve 2.

The rheostat, generally indicated at 59, has a control handle 60 for regulating the current which passes to the distributing head through the wires 61. A switch 62 mounted on the column above the rheostat has connecting Wires 63 to the rheostat which Wires are also connected in series with a red signal light 64 mounted on the outer cover ot the rheostat casing. Electric lines 65 which extend through a conduit 66 formed in the side of the column serve to supply the switch with electric current from any convenient source.

The electrical contact parts in the column are carefully insulated from each other with fiber discs and fiber discs are used for mounting plates so that if we use a metallic casing there will be no tendency to short circuit the current and burn out the fuses on the lines.

The preferred type of strap secured to the tension arms is indicated in Figures 6 and 7. The structure consists of the outer strap 26 which is fastened as noted within the clamp plate 27. A cont-act liner 67 may be suitably secured within the strap 26 with snaps 68 and a snap strap 69 extending from ends 7 O of the liner which are extended about the side edges of the strap. Between the inner liner and the outer strap pads 71 which may be suitably made of rubber are riveted or otherwise secured to the outer strap. \Vhen tension is applied it will be obvious that not only will downward pressure be attained at the back edge of the shoe band but the pads will press inwardly against the sides'of the shoe adjacent the back and by varying the shape of the pads and the shape of the form any desired shape may be obtained on the shoe. Further, in order to open out the strap during the movement upward we preferably provide spring strips 71- which are tensioned away from each other and open out the straps to provide clearance during periods of applying the work. In the modification shown in Figure 10 we have provided a curved rod which limits the movement of the strap transversely away from the form and with its bent over top 9 limits the upward movement of the strap and causes it to spread out. This modificathm is particularly useful when combined with straps which are not provided with the spring strips 71*.

To the best of our knowledge and belief no one has heretofore shaped a shoe by mounting the shoe. on a form and then compressing the shoe with outer members which not only press down on the back but which also press inwardly on the sides of the shoe.

Although we have shown a machine with a plural number of pressing units, it should be understood that the units singly provide a new usefulness in shoe shaping not heretofore known. In the claims which follow we have referred to main pressing means and auxiliary pressing means. We have further referred to means for localizing pressure. When we refer to main pressing means we have in mind the strap assembly or its mechanical equivalent. When we refer to auxiliary pressing means we refer to the pads which press inwardly on the sides of the shoes. We of course include the mechanical equivalents of these structures. To the best of our knowledge and belief no one has provided pressing means for pressing and shaping the portions of shoe elements in our preferred manner. lVhen we refer to means for localizing pressure We use this phrase to indicate pressing means which may be provided in almost any predetermined manner to various contours as is made possible by the preferred combination which we have disclosed. By varying the thickness and shape of the pads and changing their location we can bring pressure to bear on selected portions of' shoe parts which will be independent of the direct pres sure applied by the upper inner surface of the strap assembly. Thus by increasing the thickness of the pads and locating them nearer to the top of the strap we can exert all the downward pressure of the strap assembly on the curved sides of the shoes. Thus no pressure need be applied positively to the back seam of the shoe. It is the adaptability of this preferred assembly for exerting pressure in a desired part of a shoe independent of the back seam pressure which we have referred to in terms of means for localizing pressure.

The preferred type of form is indicated in Figures 7 and 8. The inner lower portion of the form is cored out as indicated at 7 2 to permit the outer sides of the form to quickly radiate ofl' heat. This structure prolongs the life of the inner liner 67 of the shaping strap which otherwise would be subjected to the heat of the form especially when low shoes were being shaped. Heat insulating material might also be used to accomplish thisrpurpose. The preferred type of shaping strap is as noted mounted on snaps so that the liner may be readily replaced when the liner is burned but as an added precaution we prefer to hollow out the form or otherwise insulate it. Inasmuch as in shaping shoes the sock lining is usually of leather. which will not stand much heat without curling We have shown the outer end of the form composed of a fiber plate 7 3 with an asbestos gasket 74 disposed between the form and the plate 73. Thus the sock lining is not heated to such an extent as the back band and sidesof the shoe with, and co-operating outer pressing memwhich it is our desire to heat particularly. By disposing the heating units 8 at an angle within the forms as indicated in Figure 8 we are further able to control the heat to the desired part'of the form, particularly for oxford shoes. The rods 9 which as noted are preferably insulated so as not to burn the straps guide the straps upwardly at an incline when the clamping arm is released so that the strap will readily slip back over the work at the start of the movement of the tensioning arm toward tensioning position. As

far as we are aware no one has previously provided a form for shoes 1n which the temper ature of selected portions of the form is conpieces or other means. Modifications will readily occur to those skilled in the art for shaping other portions of a shoe by the utilization of equivalent devices so that wedo not wish to limit ourselves to machines for the shaping of shoe backs and sides only.

In our preferred type of shoe shaper it is our desire to provide a standard set of forms for similar runs and for this reason We may provide a form which is best illustrated in the sectional view in Figure 9. The outer edge of the insulated piece indicated at A rests against the bottom of the inner side of the heel portion. The portion B is usually against the sides of the shoe on smaller sizes but not inlarger sizes. we find that the important portion of the back and sides to shape is that indicated at C and we find that irrespective of the size, a well formed shoe may be shaped at the heel end, even though the portion B does not always fit. snugly against the inner side of the shoe in all sizes. Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
