EPPLER MACHINE FOR PRESSING THE BOTTOMS O1 SHOES,

Filed y 11, 1956 Patented Mar. 9, 1937 UNITED STATES PATENT OFFICE MACHINE FOR PRESSING THE BOTTOMS F SHOES Application May 11, 1936, Serial No. 79,018 In Germany February 27, 1936 12 Claims.

This invention relates to machines for pressing the bottoms of shoes and is herein disclosed in its application to a leveling machine of the socalled automatic type.

In one well-known form of leveling machine of the automatic type the leveling operation is performed by relative movement of a leveling tool or roll and a shoe support lengthwise of the shoe and in the leveling operation the roll is automatilU cally controlled with respect to tipping movement about an axis extending lengthwise of the shoe to position it in proper relation to different portions of the bottom of the shoe, means being provided for varying the lengths of the relative movements 15 of the roll and shoe support to accommodate shoes of difierent sizes and for varying the relation of the shoe support to the roll when the roll is tipped to compensate for variations in the relative lengths of the forepart and shank portions of 2.0 shoes of diiierent styles. The shoe support comprises a toe rest provided with a rubber pad for engaging the toe end of the shoe and a spindle arranged to engage the heel end of the last in its spindle hole. The spindle is mounted for tipping movements in directions toward and from the toe rest on a heel post which is adjustable toward or from the toe rest to position shoes of difierent sizes in substantially the same relation to the leveling roll.

Such machines are usually provided with spindle-tipping mechanism and with a so-called saddle of leather which is used to transmit the pressure of the roll to the shoe in operating upon certain kinds of work and is mounted for move- S ment into and out of operative position over the bottom of the shoe for use alternatively with the spindle-tipping mechanism to jack the shoe, 1. e.

to force the toe end of the shoe firmly against the toe rest. When the saddle is used it is apii) plied tightly over the bottom of the shoe by depression of a hand lever, the spindle being tipped somewhat toward the toe rest by the action of the last thereon as the saddle is thus applied and the toe end of the shoe is depressed against the 45 toe rest. In the use of the machine, particularly in operating upon a shoe the bottom of the forepart of which is inclined upwardly and rearwardly from the toe end of the shoe, there is a tendency for the pressure of the leveling roll on that portion of the shoe to displace the shoe rearwardly relatively to the toe rest, thereby varying the relative longitudinal position of the shoe and roll and afiecting the action of the roll on the different portions of the shoe bottom.

59 With the saddle applied tightly over the bottom of the shoe it is desirable that the spindle be locked against tipping movement in a direction away from the toe rest so as to prevent any such displacement of the shoe relatively to the toe rest in the pressure-applying operation.

An object of the invention is to provide improved means for accomplishing that result. For the purpose in view, there is provided, as herein shown, a locking device comprising a member having a series of teeth formed thereon and a. pawl arranged to engage some one of the teeth to lock the spindle against tipping movement. More particularly, in the construction shown, the pawl is movable in a direction lengthwise of the series of teeth in response to tipping movement of the spindle toward the toe rest, and means controlled by the above-mentioned hand-lever is provided for moving the pawl into engagement with one of the teeth after the movement of the hand lever to force the saddle against the shoe has been substantially completed. Thus the spindle is permitted to tip toward the toe rest as the saddle is forced against the bottom of the shoe but is locked against reverse tipping movement in the pressure-applying operation. As herein shown, there is provided a roll which is movable with the above-mentioned hand lever and is arranged to engage a rib on the pawl. The rib is curved lengthwise of the series of teeth and is held in engagement with the roll by spring means, the curvature of the rib being such that the pawl is moved into engagement with one of the teeth after the movement of the pawl lengthwise of the series of teeth has been substantially completed. Conveniently, this means is also utilized to render the locking device inoperative by the movement of the saddle out of operative position over the bottom of the shoe. As illustrated, the roll is carried by an arm which is swung in a direction to move the pawl into an inoperative position by the movement of the saddle out of operative position, a latch being provided for holding the pawl in the position into which it has been moved by the movement of the saddle into its idle position.

The above and other features of the invention including various novel details of construction and combinations of parts will now be more particularly described by reference to the accompanying drawing and thereafter pointed out in. the claims.

In the drawing,

and

Fig. 2 is a view partly in rear elevation and partly in section of parts of the locking device for the spindle.

Since the invention is illustrated as applied to a leveling machine of a well-known type only such parts of the machine as it is necessary to refer to for an understanding of the invention are shown and will be described in detail. Features of the general organization of machines of this type are disclosed in various. prior United States Letters Patent including Letters Patent No. 1,667,761, granted on May 1, 1928 and No. 1,719,158, granted on July 2, 1929, both upon applications of E. E. Winkley and H. A. Davenport. It will be understood that the machine includes an automatically controlled leveling roll l6 and a shoe support or jack which in the. power operation of the machine is moved automatically in directions lengthwise of the shoe to cause the roll to operate progressively along the bottom of the shoe. The jack comprises a toe post l2 and a heel post l4 which are pivoted together for relative adjustment for shoes of different sizes by means of a threaded adjusting rod (not shown) which moves the heel post toward or from the toe post so that the toe ends of shoes of different sizes will be presented in substantially the same relation to the roll it. The jack as a whole is operatively movable about the axis of a shaft (not shown) on which the toe post is mounted, and power-operated means, not herein shown, is provided for imparting to the jack oscillatory movements about this axis to carry the shoe rearwardly and forwardly under the leveling roll. The toe and heel posts are provided with means for supporting a shoe and last for the leveling operation. Mounted on the toe post I2 is a toe rest comprising a block I 6 having secure-d to it a rubber pad l8 for engaging the toe end of the shoe. The heel post M at its upper end supports a block 20 carrying a spindle 22 arranged to enter the spindle hole in the heel end of the last. The block 29 is mounted on the heel post for swinging movements about an axis extending laterally of the shoe to permit the spindle to tip in directions toward and from the toe rest. .The spindle 22 extends through an enlarged opening in a plate 24 also carried by the block 29, which plate is free to tip about an axis extending laterally of the shoe to adjust itself to the top face of the cone of the last. The block 20 is connected by a link 26 to mechanism which will presently be described whereby the block and spindle may be swung to press the toe end of the shoe firmly down upon the toe rest.

For use in jacking a shoe alternatively with the spindle-tipping mechanism just referred to there is provided as heretofore in machines of the type herein shown a saddle 2B of flexible leather which, as illustrated, is of such length as to cover the entire bottom of the shoe and is connected at the opposite sides of its shank portions by springs 30, one of which is shown in Fig. l, to the two arms 32 of a bifurcated hand-lever 34 which is utilized to apply the saddle tightly over the bottom of the shoe in the same general manner as illustrated in Letters Patent No. 1,7 04,822, granted on March 12, 1929 upon an application of H. A. Davenport, one of the arms 32 of the hand-lever being shown in Fig. 1. Each spring 30 at its upper and lower ends engages spiral grooves formed in pins 36, 38 which project respectively from end members 49, 42, each member 40 being pivotally connected to a plate 44 fastened to the saddle 28 and each member 42 being pivotally.

connected at 46 to one of the arms 32 of the hand lever 34. To assist in holding the full-length saddle in place there are provided additional springs 48 connected to the opposite sides of the forepart portion of the saddle and to the arms 32 of the hand-lever 34. When the saddle is used the lever 34, the arms of which are pivoted at 50 to blocks slidingly mounted in slots 52 on the toe post l2, pulls it down tightly over the shoe and is then looked to a segment 54 on the heel post. The slots 52 are concentric with the pivot about which the heel post is movable toward or from the toe post to permit relative adjustment of the toe and heel posts without disturbing the relation between the hand lever 34 and the heel post I4.

The relation of the lever 34 to the spindletilting mechanism will now be described. As fully shown and described in the above-mentioned Letters Patent No. 1,719,158 there is pivotally connected to the lower end of the heel post 14 a link 56 having pivotally connected to its upper end links 58, one of which is shown in Fig. 1. The links 58 extend, one on each side of the heel post I 4, toward the toe post 82 and are connected to the arms 32 of the hand lever 34 by short upwardly extending links Bil. Depending from the two links 53 are arms 59 connected by a horizontal pin 62 extending through a slot 64 formed in a member 66 connected to the lower end of the link 26 (Figs. 1 and 2). Pivotally connected to the member 66 is a member 68 which may be swung up into position to serve as an abutment for the horizontal pin 62, or down, as shown in Figs. 1 and 2. member 68 is in the latter position the pin 62 has free movement in the slot 64 as the lever 34 is swung downwardly sothat no motion is im parted to the link 26 in operating the saddle. When the member 68 is in its uppermost position, in which position it is held by the engagement of a spring-pressed pin 19 in the member 66 with a recess 72 in the member 68, downward movement of the lever 34 forces the link 26 downwardly to operate the spindle by engagement of the pin 62 with the member 68. The spindle 22 is normally held tipped toward the toe support by means of a spring 14 extending between one of the links 58 and a pin 76 projecting from the link 26. The mechanism for thus rendering the lever 34 efi'ective to operate either the saddle 28 or the link 26 is substantially the same as that shown and described in the above-mentioned Letters Patent No. 1,719,158.

For purposes of this invention there is secured to the heel post l4 (Fig. 1) a plate 78 having teeth 80 formed thereon which are arranged to be engaged by one or another of a plurality of pawls 82 pivotally mounted upon a pin 82 which connects the member 66 to the link 26. The pawls 82 (Fig. 2) which, as shown, are four in number, are mounted on the pin 84, two on each side of the link 26, which is provided with a plane lower end face held in engagement with a shoulder 86 on the member 66 by the pin 84. The pawls 82, which are preferably of slightly different lengths for better insurance that the link 26 will be locked in whatever position it assumes by tipping of the spindle 22 when the saddle is forced down on the shoe, are urged toward the ratchet teeth 80 by U-shaped springs 88 coiled about the opposite end portions of a bolt 90 carried by the link 26. When the saddle 28 is in position over the bottom of the shoe downward movement of thehand-IeVer 34 acts through the springs 30 and 48 to apply the saddle tightly over the bottom of the shoe, the pressure of the saddle on the shoe acting to force the toe end of the shoe into the rubber pad 18 of the toe rest. As the toe end of the shoe is thus firmly seated on the toe rest the spindle 22 and block 28 may be tipped somewhat toward the toe rest by the action of the last thereon, the block 20 being tipped in a direction to move the link 29 and the pawls 82 downwardly, and the construction being such that with the lever 34 locked to the segment 54, the spindle and block are locked against reverse tipping movement from the position into-which they have been moved by the last by the engagement of one of the pawls 82 with one of the teeth on the plate 18. There after as the jack is swung in directions lengthwise of the shoe under the roll ID in the power operation of the machine the shoe and last are held by the spindle 22 against displacement relatively to the toe rest as the pressure of the roll 19 is applied through the saddle 28 to the upwardly inclined bottom face of the forepart of the shoe.

For moving the pawls 82 relatively to the plate 18 to release the block 20 and spindle 22 for reverse tipping movement to permit the shoe and last to be removed from the jack after the completion of the pressure-applying operation, the right-hand end pawl 82 (Fig. 2) is provided with a curved rib 92 arranged to be engaged by a roll 94 carried by an arm 96 extending from one of the members 42 (Fig. l). Projecting from the end pawl 82 is a pin 98 arranged to engage tail portions I80 formed on the remaining three pawls.

When the hand lever 34 is unlocked from the segment 54 and swung upwardly to idle position the end pawl is swung away from the plate 18 by the action of the roll 94 on the curved rib 92 as the member 42 and the arm 95 move upwardly with the hand lever. It will be evident that as the end pawl is thus swung out of engagement with the teeth 80 on the plate 18 the remaining three pawls are also swung out of engagement with the teeth 89 with the end pawl by engagement of the pin 98 with their tail portions I98. Preferably, as shown, the pin 98 is eccentric so that it may be adjusted to permit the remaining three pawls to assume slightly different positions relatively to the end pawl with one of the pawls in locking engagement with the teeth 89 when the pawls are in the positions shown in Fig. 1. It will be understood that the shape of the curved rib 92 is such that when the handlever 34 has been moved into idle position all the pawls 82 will have been moved out of engagement with the teeth 89.

The pivotal connections 48 between the members 42 and the arms 32 of the hand lever 34 ermit the saddle 28 to be swung either to an idle position at the rear of the heel end of the shoe in which position it is usually draped over the hand lever 34, or to an operative position over the bottom of the shoe, as shown in Fig. 1. As the saddle is swung to its idle position the arm 98 is swung in a direction to cause the roll 94 by engagement with the curved rib 92 of the end pawl 82 to impart a further swinging movement to the pawls 82 in a direction away from the plate 78, this movement of the pawls being limited by the engagement of a shoulder I92 on the above-mentioned end pawl with the shoulder 89 on the member 66. For locking the pawls 82 in their outermost positions there is pivotally connected to the member 66 a latch I94 which may be swung upwardly into position to engage a shoulder I06 on the end pawl 82. It will be evident that as the end pawl 82 is swung away from the plate 18 by the swinging oi the arm 96 in the movement of the saddle into idle position the pin 98 by engagement with the tail portions I00 of the other three pawls will swing them outwardly with the end pawl and will also act to hold them against inward swinging movement relatively to the end pawl with the latch I04 in engagement with the shoulder I86 on the end pawl.

It will be readily seen that with the saddle in its idle position and the pawls 82 held in their outermost positions by the latch I84 the shoe support may be used as heretofore in jacking a shoe after swinging the member 68 upwardly into position to be engaged by the pin 62 in the downward movement of the hand lever 34. When it is desired to use the saddle 28 the latch N14 is swung downwardly into the position shown in Fig. 2 and the saddle 28 is moved into position over the shoe by swinging it forwardly. It will be understood that before the saddle is moved into position over the shoe the operator willmount a shoe and last on the spindle 22 and will swing the spindle 22 and block 29, against the resistance of the spring 14, in a direction away from the toe rest by elevating the toe end of the shoe into position to engage the rubber pad l8 on the toe rest. Thereafter with the saddle in position over the bottom of the shoe the handlever 34 is swung downwardly to apply the saddle tightly over the shoe and to force the toe end of the shoe firmly against the rubber pad 18. As the hand-lever 34 is swung downwardly the springs 88 act on the pawls 82 to hold the curved rib 92 on the above-mentioned end pawl in engagement with the roll 94. In order to prevent wear oi the pawls 82 and teeth 80, the shape of the rib 92 is preferably such that the pawls 82 are held out of engagement with the teeth 80 on the plate 18 until after the movement of the hand-lever 34 to force the saddle 28 tightly against the bottom of the shoe has been substantially completed, whereupon one of the pawls 82 becomes effective by engagement with one of the teeth 80 to lock the spindle 22 and block 29 against reverse tipping movement with the hand lever 94 locked to the segment 54. Thereafter, as the handlever 34 is swung upwardly to idle position after the completion of the pressure-applying operation, the roll 94 by engagement with the curved rib 92 swings the end pawl and through the pin 98 the other three pawls out of engagement with the teeth 80, the pawls being thus swung substantially at the beginning of the upward movement of the hand-lever 34 by reason of the curvature of the rib 92,
