This invention relates toshoe-shaping machines and, as herein illustrated, isembodied in a machine for shaping shoe-upper parts, it being particularly applicable to shaping the top margins of substantially completed shoes.

In the manufacture of shoes,it is frequently found that the withdrawal of the-making last destroys the shape of the shoe, especially around the ankle opening. This is especially noticeable with pumps and the like, and gives to the shoe an unsightly and wrinkled appearance which lessens its saleability. Frequently, the ankle opening of the shoe gapes open unduly.

Accordingly, an important object of the invention is to provide an improved machine for shaping shoe-upper parts to restore to the shoe the intended shape which was imparted thereto by the last.

In carrying out this object, the machine herein illustrated embodies a-shoe-supporting form which may readily be inserted in a shoe and later withdrawn without disturbing the shape which has been imparted to the shoe. Coacting with the form are pressers for engagement with the outside of the shoe to mold the shoe to the shape of the form. In accordance with a feature of the invention, the shoe-supporting, form ismounted'on a support for limited movement,

both lengthwise of the shoe and laterally thereof, the latter arrangement insuring the application of a uniform pressure-on the opposite sides of the shoe as the pressers are brought into engagement therewith;

The accessibility of the shoe-supporting form,

enabling the shoe to be applied thereto and removed with ease, is increased, in accordance with another feature of theinvention, by mounting the pressers for movement not only laterally toward and away from the shoe but also heightwise In the illustrated construction, this is effected by means of pressers which are pivotally interconnected at .increasel the pressure and to retainthe applied pressure for a. desired interval.

As illustrated, a plurality of molding mechanisms are mounted on a turret, rotatable stepby step, to bring successive shoe forms to a loading, position.

During this rotation of theturret, the machine is arranged-in accordance with other features of the invention, so that an operating deviceassociated with each molding mechanism engages with a fixed cam to cause the application of pressure. As the turret approaches completion of its cycle, another fixed camoperates to relieve the applied pressure, breaking the toggle of the struts and releasing a holding latch.

. For ease, and safety of operation of the machine, a novel arrangement. is provided of an operator-controlled treadle, which, ,when depressed, appliesthe preliminary pressure and, when released, actuates a clutch to start the movement of the turret. The application of preliminary pressure is effe'cted through a plunger located at, the center of the turret. Danger to the operators fingers is minimized by arranging the treadle so that the turret cannot ,be started thehe'el endand slidably mounted in a carrier movable longitudinally of the shoe. Thesliding movement of the pressers in the carrier is heightwise of the shoe.

Still another feature of the invention resides in an improved mechanism for applying, a force to move the pressers laterally against the shoe.

This mechanism, as illustrated, comprisestogglelike struts resting at their outer ends against abutments and at their inner ends engaging the f shoe pressers. Preliminary pressure is first applied. by the operator" and then' power is applied to move the struts past dead center thereby to the right of Fig. l;

to, apply full pressure until after the pressers have been brought fully into engagement with the shoe by (initial depression of the treadle.

Provision is also made for preventing premature depression of the treadle while the turret is still rotating, thus avoiding a possible breakage of machineparts. A

These and other features of the invention will be best understood from a consideration of the following description, takenin connection with the accompanying drawings, in which Fig. 1 is an elevation of the machine but showing only a single shoe shaping or molding mechanism;

Fig. is a similar section, enlarged, on the line XX of Fig. 4, but with a shoe on the form. The machine is of the turret type and comprises a plurality of operating mechanisms in each of which there is a shoe-upper-supporting form [2 and cooperating molding members or pressers M and I6 supported indirectly on a bracket I8 carried by a rotatable table 20. Preferably, six such molding mechanisms are provided on the table 29, although, for simplicity of illustration, only one has been shown. Secured to the table is a worm wheel 22 by which the table is rotated by a cooperating worm 24 on a shaft 26 which receives power from a drive pulley 28 through a clutch mechanism 31]. The arrangement-is such that preliminary pressure is applied to the shoe upper by the pressers N and [6 which are moved forwardly, downwardly and then inwardly toward the side of a shoe under the impulse provided by an operator-controlled treadle 32 pivoted on a bracket .attached to a hollow base pedestal" 34 and which serves also, inja manner to be later described, to operate a clutch-controlled mechanism, shown in Fig. ,2, to cause-the table 29 to rotate for one-sixth of a revolution. During. this rotation, pressure is applied automatically to the pressers i4 and 16, which pressure is maintained throughout the greater part of a revolution of the table and then is released as the particular shoe-supporting form l2 returns to starting or loading .position.

A suitable indexing mechanism, to be described, is provided to causethe turning of the table to be stopped after each sixth of a revolution.

Each of-the shoe-supporting .forms 12 is posidirection extending substantially normal to the tread surface of the sole of the shoe.

or counter portion higher than the upper end of theform, causing the lower end of the form to be inserted first into the ankle opening, after which the heel end of the shoe is dropped to bring it into engagement with the narrow upper end of the form. To facilitate the positioning of the shoe on the form, the latter is provided with a forwardly tapering, offset portion (Fig. 4)

having a protective plate 42 of fiber or the like so'that when the form is heated, as by means of an electric cartridge unit 44, there will be no marking of the inside of the shoe. Heating the form facilitates the molding of the shoe and may be used to shrink and iron the lining. This wedge-shaped extension ll] permits the shoe to be moved toward the machine until the fiber .plate d2 engages the inside of the bottom of the shoe, whereupon it will be found that, the upper edges of the shoe lie substantially vertically along the form I2 ready for the action of the pressers Each of the forms l2 has a fin 4S projecting rearwardly toward the center of the .machine and'terminating in a substantially cylindrical portion 48 (Fig. 10) which is received in a correspondinglyshaped slot 50 (Fig. 9) extend- "the vertically of the forward edge of the bracket id. The side edges 52 of this slot are cut back to allow a limited lateral swinging movement of the form in the bracket slot. Downward yielding A shoe may be presented to the formv with its heel end movement of the form in the casting is provided, against the resistance of a spring 54 which is received in the bore 56 of the cylindrical portion 48 to rest against the upper end 58 (Fig. 4) of that bore and against an arm 80 attached to the bracket I8. Upward movement of the form with respect to the bracket by the spring 54 is limited by means of a rod 62 extending through the bore 56 and the arm 60, this rod being provided with a knurled head 64 and with a nut 66 at the top and lock nuts 68 below the bracket I35. The uppermost position of the form with respect to the bracket may be adjusted by holding the knurled head 64 of the rod and turning either the nut 66 or nuts 68.

The pressers l4 and it are shaped substantially complementally to the shoe-supporting form l2, being substantially flat at their upper ends near the heel end of the form and being concave lower down, as shown in Fig. 10. Preferably, they are provided with work-engaging surfaces of a yieldable nature and, as shown in Fig. 10, comprise each a layer of leather l0 which may be riveted to the pressers and a layer of rubber l2 held in place by a thin, flexible, leather cover M tightly wrapped around the assembly and held in position by a lacing 76 (Fig. 4), By these members, pressure is applied to a shoe S chiefly along the upper edges thereof and will impart the shape of the form [2 to the shoe, thereby to determine the shape of the ankle opening.

As has been previously noted, these pressers l4 and I 6 are supported for movement forwardly (i. e., outwardly from the machine and heightwise of the shoe), and downwardly, i. e., lengthwise of the shoe, and also inwardly of the shoe .heightwise of a shoe on the form, i. e., in a after the shoe has been positioned on the form. To this end, there is provided (Fig. 4) a carrier 89 supported on the upper end of a plunger 82 vertically slidable in a bore provided in the bracket l8 and normally held in upward position by a compression spring 84. The pressers are pivotally interconnected and, for this purpose, the upper end of the presser I4 is provided with a flange 86 which is bolted to a flange 88 formed integrally with a horizontal rod 99 (Figs. 7 and 8) passing through the carrier 8!]. Surrounding this red is a rotatable sleeve 92 on the forward end of which is a flange 94 to which is bolted a flange 95 (Fig. 6) at the top of the presser l6. This concentric rod and sleeve supporting the pressers are normally drawn rearwardly toward the center of the machine in the carrier by means of springs 93. In order that the pressers l4 and I6 may normally be held away from the shoesupporting form l2, the rod has a screw pin I00 joined by a spring 72 to another pin I04 which is threaded in the sleeve 92. The pin I06 passes through a slot IE6 in the sleeve 92. In order that the degree of swinging movement may not be unlimited and that the pressers may be held in substantially the desired relation to the form l2, the pins Hill and H34, which are attached indirectly to the pressers, are positioned in slots I08 and H0 (Figs. 4 and 7) in the carrier 80. Thus, any substantial swinging movement of the pressers bodily together in the same direction when they are in a raised, open position is prevented.

Provision is made, as has already been noted, for the application of a preliminary pressure by the members l4 and It to a shoe supported on the form [2 and, for this purpose, the plunger 82 is provided with a rearwardly extending pin 1 l2 carrying a roller H4, the pin passing through a slot in the bracket I8 in which this plunger is supported. This roller is adapted to be engagedon its upper surface by the forward end of a lever II6 which is pivoted on a stud II8 within a fixed bracket I20. This bracket I is clamped by bolts I22 on the upper end of a hollow rod I24 which projects upwardly through a bore in the table 20 and is carried by the base pedestal 34. The rear end of the lever II6 projects through a slot into the bore I26 within the rod I24 where it overlies the upper end of a plunger I28 slidably mounted in this bore and connected by a rod I30 to the end of the treadle 32 which projects inside the pedestal 34. This rear end of the lever H6 is biased toward the plunger I28 by a spring I29, the downward movement of the rear end of the leverbeing limited by a stop screw I3I. When the treadle is depressed against the tension of a spring I32, the forward end of the lever I I6 is depressed, moving the carrier 80 downwardly. During this movement, the pressers are moved forwardly by reason of the engagement of a roll I34 with a groove I36 in a cam I40 rotatable on a shoulder near the upper end of the rod I24. The shape of this cam groove I36 is such that the outward movement of the pressers is completed before they drop into contact with the shoe. The roll I34 is pivoted in a casting I42 having a stud loosely fitting a bore I44 (Fig. 7) at the rear end of the rod 90 so that it is free from swinging with the pressers. Rotation of the casting I42 with the rod 90 is prevented by a guide bar I46 attached to the upper side of the carrier 80 and received in a slot in the upper edge of the casting I42.

As the treadle is depressed, therefore, the pressers are moved forwardly and downwardly and this downward movement is accompanied by movement of the lowers ends of the pressers toward each other by a mechanism shown best in Fig. 6. This movement of the pressers inwardly against the shoe is effected by pivoted struts I50 received in horizontal recesses I52 provided in the outer sides of the pressers and terminating at their upper edges in shoulder abutments I54. The struts are pivotally supported on abutments formed at the upper end of arms I56 secured to the bracket I8 andextending outwardly and upwardly to provide ample space around the lower end of the form I2. This gives greater freedom for manipulation of the shoe as it is applied to the form and in case the shoe is provided with straps, suflicient room is provided so that these straps will not be caught in other mechanism. Rounded faces I18 at the lower edge of the recesses I52 prevent the struts I50 from falling below the pressers I4 and I6.

Each of the strutsis forked at its outer end and pivoted to an abutment I60 slidably received in a cup-shaped member I62 in a horizontal bore in thecorresponding .arm I56 andheld in position therein by nuts I64 and I66 threaded onthe externalsurface of the member I62. At the inner end of .each of the cup-shaped members I62 are slots I66 receiving reduced portions of the support I60 so that the abutment cannot turn relatively to the cup-shaped member. On the abutment is a rod I'I0 surrounded by a compression spring N2, the resistance of which may be adjusted by means of a nut I'I4 threaded on the rod I10. Thus, the strut abutment I60 can yield outwardly against the action of this spring I12. In order to maintain the spring adjustment, a lock screw I16 is threaded in the outer end of the nut I'I4. By adjusting the nuts I64, I66,

'wheel 22 and the worm 24.

the lateral position of the abutment for the strut I50 may be adjusted bodily without altering the compression of the spring I'I2.

' When the pressers I4 and I6.are moved downwardly and forwardly as the plunger 82 is pushed down, the rounded upper ends of the struts I50 will track-along the recesses on the external surfaces of the pressers and come into engagement with the shoulder abutments I54, the continued movement of which will move the struts downwardly about their pivots, and this, in view of the inclination of the struts, will serve to urge the pressers toward each other. The arrangement is such that when a shoe is on the form and the pressers I4 and I6 are lowered to effect a molding operation, the strut members I50 will be carried with the pressers through and slightly below the horizontal to form a toggle and will then serve to hold the pressers in lowered position and in firm engagement with the sides of the work, even though pressure is no longer applied to the roll II4 on the plunger 82. The degree and manner of application of the pressure exerted against the sides of the shoe may be adjusted by turning the nuts I64, I 66 and H4.

Prior to this application of full pressure which will carry the struts I60 beyond their dead centers and so hold the pressers in shoe-engaging position, it is desirable to maintain the preliminary pressure which has been applied through the treadle, the plunger I28 and the lever II6. To this end, the plunger 82 is provided with a ratchet plate I (Fig. 4) extending through a I slot in that portion of the bracket I8 which guides the plunger 82. This ratchet is provided with teeth which are engaged by a pawl. I02, pivoted on the bracket and held normally in engaging position by means of a tension spring I84.

As has been already mentioned, provision is made'for rotation of the table 20 to carry successive shoe supports from loading position around the table and back to loading position again, this being effected through the worm As the illustrated work support leaves the loading position with the table. rotating counterclockwise, when viewed from above, the roll II4 on the plunger 82 will pass under a cam I88 (Figs. 3 and 5) having an inclined operating surface I90 and which is adjustably secured to the side of the bracket I20. To this end, the bracket is provided with a vertical groove I92 (Figs. 4 and 5) and the cam is held in position by bolts I94 entering the threaded holes I96 in the bracket. The operative surface I90 of this fixed cam inclines downwardly to the right and as the table is turned, the plunger 02 willbe depressed to a point such that the struts I50 are depressed below their horizontal positions before the roll II4 leaves the cam surface thereby insuring that the full molding pressure will be maintained throughout the remainder of the rotation of the table or until positively relieved During this turning movement, the grooved cam I40 at the top of the rod I24 will be turned by engagement of the rolls I34 in said grooves and will be revolved about the axis of the table. When a rotation of the table is nearly completed, the cam roll II 4 will engage the top inclined surface 200 of a cam member 202 which is adjustably secured to the bracket I20 in a manner similar to that in which tail 204 of the pawl I82 will engage an inclined surface 206 (Fig. 4) on a cam plate 208 adjustably secured to the bracket I20, as by screws 2 I0, thereby releasing said pawl and allowing the plunger 82 to be pushed upwardly by the cam surface 265 far enough to break the toggle effect of the struts I50. The spring 84 will then be effective to continue the upward movement of the presser carrier 80 and the pressers, released from the cam I40, will be drawn away from the shoe by the combined action of the cross spring I02 and the side springs 98. When the particular shoe support I2 reaches loading position, the tail 284 of the pawl I82 will ride down an inclined surface 212 ready for reengagement with the ratchet I80 and the roll I I4 will be positioned in a gap between the two cams I88 and 200 ready for the action of the treadle-operated lever II6 after the treated shoe has been removed and another one put in its place.

It has already been explained that the table 20 is provided with six work supports and molding devices. It is desired, therefore, that the driving apparatus shall automatically move the table I one-sixth of a revolution and bring it to a stop.

This is done by a table-turning mechanism similar to that described in British Patent No. 343,151. To this end, the worm wheel 22 (Fig. 2) has on its under surface a cam groove 220 provided with six depressions in its inner vertical face corresponding to the six shoe supports. When the machine is stopped, a roll 222 attached to a slide 224 urged to the left by a spring 226 engages one of these depressions. When the machine is started, in a manner to be presently described, by clockwise movement of a trip lever 23!) against the tension of a spring 232 and the consequent raising of the tail of this lever, the cam surface in the groove 229 will cause the slide 224 to be moved toward the right in Fig. 2, with the consequent raising of an arm 233 pivoted in a bracket 256 on the frame. This arm 233 has a screw 234 which is raised into a position to keep the tail of the trip lever 232 raised, even when the clutch treadle is released to allow the clutch to remain in engagement until the table has rotated a sixth of a revolution. This position of the trip lever 230 is maintained until the next depression in the groove 220 comes into position to receive the roll 222 as one of the work supports comes into position at the loading station, whereupon the slide 224 is moved to the left, the screw 234 lowered and the trip lever 230 permitted to rise to cause declutching, as will be described.

The clutch 33 may be of any desired type. It will be assumed here, however, to be arranged as illustrated in Letters Patent of the United States No. 1,124,620, granted January 12, 1915, on an application of A. E. Jerram, in which case a clutch member 236 will correspond to the pendent lever I34 of that patent. The treadle 32 is utilized to actuate the clutch mechanism in addition to operating the plunger I28. For this purpose, a crank arm 240 is provided which is fixedly secured to the shaft 242 which rocks with the treadle. The arm 240 is connected by a link 244,

arms

246, 248 fixed to a rock shaft 250 and an adjustable rod 252 to one end of a lever 254 pivoted on a fixed bracket 256. The clutch-tripping arrangement is seen in Fig. 2. The lever 254 has pivoted to it at its end opposite to that to which the rod 252 is attached, a latch 258 which has a shoulder or hook for operating the clutch trip lever 230. The arrangement is such that the hook on the latch 258 is normally located below the cooperating portion of the clutch trip lever 232. On depression of the treadle 32, however, the latch 25B is moved upwardly to bring the hook on the latch above and over the end of the trip lever 23!]. When the operator relieves the pressure on the treadle, the spring I32 raises the treadle. The latch 258 is consequently moved downwardly and its hook carries the right-hand end (Fig. 2) of the lever 230 downwardly, thereby effecting tripping of the clutch, the latch 258 being freed from the lever 230 by movement of the pendent member 236 to the right as the clutch is actuated.

When the treadle 32 is depressed to cause the pressers I4, I6 to move forwardly and downwardly and then inwardly toward the shoe to apply preliminary pressure to work on the form I2, such preliminary pressure as is applied is maintained by the cooperation of the pawl I82 with the ratchet teeth on the plate I80. In the arrangement shown in the accompanying drawings, the rod 252 is of such length (or is adjusted to be of such length) that, when the treadle 32 is depressed, the hook of the latch 258 is not raised above the end of the lever 239 until the pressers have been lowered through such a dis tance that the ratchet plate I80 has reached a position in which its second tooth from the lower end can be engaged by the pawl I82. Thus, until the pressers I4, I6 have been lowered to this extent, release of the treadle will not cause tripping of the clutch. This provides a safeguard against the operator getting his or her fingers trapped between the pressers I4, I5 and the inside form I2 and injured by the power application of pressure. When the pressers I4, I6 have been lowered to the extent indicated (that is, to an extent at which the second tooth on the ratchet plate I80 can be engaged by the pawl I82) by depression of the treadle, these members will so closely embrace the work that there is not room between them and the work for the operators fingers to be trapped therein. Conversely, should the operators fingers be trapped as the pressers are lowered by the treadle 32, the operator will instinctively release the treadle well before it has been lowered enough to bring the parts into such a position that release of the treadle will cause tripping of the clutch and consequent application of the full pressure under power.

As another safeguard, the lever I I6 has a rollengaging portion consisting of a member 260 pivoted to the end portion of the lever. When the clutch has been tripped and the roll II4 of the molding mechanism which was at the loading station has been carried from underneath the lever IIB, the latter is held by the spring I29 with its left-hand end (Figs-l and 3) in raised position. At this time, a small spring 262 holds the pivoted member 260 in such position that a tail 264 on the member 260 engages a step 256 on a fixed plate 268 carried by the bracket I 20. Thus, in such position of the parts, it is not possible to turn the lever H6 by depressing the treadle 32. This prevents the operator from prematurely depressing and releasing the treadle to cause the next tripping of the clutch before the next molding mechanism has been carried right around to the loading station and its roll II4 brought underneath the lever II6. When the roll II4 is moving into this position, it is traveling upwardly along the inclined face 280 of the cam member 202. In so traveling, it engages the pivoted member 260 and moves it up (clockwise in Figs. 1 and 4) to disengage the tail 264 from the step 266. The lever H5 is then permitted to be turned about its pivot on depression of the treadle 32. The arrangement described prevents the machine suffering damage through times, though infrequently, occur. If the operator on depressing the treadle 32 releases it at such a stage that the pawl I82 engages the first ,tooth (from the lower end) of the ratchet plate I80, the clutch will not be tripped but the roll II4 of the molding mechanism at the loading station will be held by the pawl depressed below and spaced from the member 260 which will have been raised by the lever I I6 when the treadle was released and, consequently, the tail 264 will latch against the step 266, preventing the treadle being depressed and released once again to effecttripping of the clutch. In such case, the operator will manually release the member 260 by means of the extension 210 to allow the treadle 32 to be operated.

In using the machine, the operator will remove the treated shoe from the form I2 at the loading station and replace it with another shoe which he will push against the form until the inside of the heel seat portion of the shoe engages the fiber plate 42 and the heel end or counter portion of the shoe rests snugly against the heel end of the form. Then, he will depress the treadle 32, thus raising the plunger I28 and causing depression of the plunger 82 and the carrier 88 mounted thereon. By this movement, the pressers will be movedforwardly or toward the bottom and, hence, height-wise of the shoe and downwardly or longitudinally of the shoe by the action of the grooved cam I40. When the downward movement is partly completed, the struts I50 will be engaged by the shoulder abutments on the pressers and pushed downwardly-toward a horizontal position thus forcing the pressers inwardly against the sides of the shoe. occurs, the form may yield vertically, if necessary, and the pressure will be equalized by the provision for limited lateral movement of the form. Whatever pressure is applied will be retained by the action of the latch I82. Thereupon, as the treadle is released, the clutch will be actuated in a manner already described and the turret given one-sixth of a revolution, thereby carrying the roll on the plunger 82 beneath the cam surface I99, thus still further depressing the carrier 80 and forcing the struts pastdead center so that they act as a toggle and hold the pressers in engagement with the shoe. This continues until the turret rotates far enough so that the toggle is broken by the action of the cam surface 200, the pawl I82 being also released by the Asthis.

cam 20B, thereby allowing the spring 84 to force up the plunger on which the carrier 80 is mounted. The pressers will then be drawn laterally away from the shoe, vertically above the shoe and then back, heightwiseof the shoe, leaving the latter free for removal from the form.
