(c1. lz-an 3l Claims.

This invention relates to machines for shaping or leveling the bottoms of shoes, and is herein illustrated as embodied in a leveling machine of the type disclosed in Letters Patent of the United States No. 2,230,244, granted February 4, 1941, upon an application filed in the names of F. V. Hart and J. J. Austin. It is to be understood, however, that in its more general aspects the invention is not limited to machines of the particular type illustrated.

Machines of the above-mentioned type comprise in their organization a leveling tool, such as a spring-pressed roll, a shoe support which is adjustable to accommodate shoes of different sizes, and power-operated means which is continuously under control of the operator for limparting to the shoe support swinging movements in opposite directions lengthwise of a -shoe lthereon to cause the leveling roll to operate progressively along the shoe bottom. Such machines are also provided with other power-operated means also continuously under control of the operator for imparting to the leveling roll tipping movements in opposite directions laterally of the shoe to vary its inclination in operating upon the opposite marginal proportions of the shoe bottom, a hand lever being provided for controlling each of the above-mentioned poweroperated means. By means of the appropriate hand lever the operator is enabled to start, stop or reverse the swinging movement of the shoe support or the tipping movement of the leveling roll and to determine variably, by the extent of movement of the hand lever in either direction,

the extent of rearward or forward swinging '1 movement of the shoe support or the extent of tipping movement of the leveling roll in one direction or the other laterallyof the shoe. In the use of the machine, for example on shoes of a style characterized by a pronounced line or ridge across the sole at the ball line, it is necessary for best results that the movements of the shoe support be controlled with such accuracy as to cause the sole to be leveled only up to such a line or ridge so as to accentuate it. While such a machine is under substantially as full control of the operator as if he were operating it manually, it is sometimes difficult to determine the exact point in the operation of the roll on the shoe bottom at which to stop the swinging movement of the shoe support so as to insure such results while preventingy the roll from obliterating such a line or ridge.

An .object of .the present invention, accordingly, is to provide in a machine ofthe abovementioned type means for automatically terminating the movement of the shoe support in either direction lengthwise of the shoe each time in the operation of the machine when the leveling roll is located nearly at the junction of the forepart and shank portions of the shoe bottom. For the purposes in View, the construction shown comprises a stop movable by the shoe support and a member or plate having formed thereon spaced shoulders, one of which is arranged by engagement with the stop to prevent movement of the shoe support in one direction beyond a position in which the leveling roll is located substantially at the junction of the forepart and shank portions of the shoe bottom and the other shoulder of which is arranged by engagement with the stop to prevent movement of the shoe support in the opposite direction beyond a position in which the leveling roll is nearly in the same location on the shoe bottom. Machines of the type illustrated in the above- Amentioned Letters Patent also include in their organization means enabling the o-perator at will to cause the lifting of the leveling roll from engagement with the shoe, and in accordance with a further feature such means is utilized to operate means for moving the movable stop outl of operative relation to either one of the abovementioned shoulders to permit movement of the support beyond the position determined by that shoulder. Preferably, as shown, the shoulders are so shaped as to vary the extent of swinging movement of the shoe support in accordance with variations in length of the forepart and shank at the opposite sides of the shoe bottom, and novel mechanism isprovided for moving the plate relatively to the movable stop in opposite directions in response to the tipping movements of the leveling roll in opposite directions, this mechanism comprising connections that are adjustable by the operator to cause the plate to be moved in the same direction for operating upon either the inside or the outside marginal portions of both left and right shoes.

In a further aspect, the invention provides novel means for preventing movement of the shoe support in a rearward direction in operating on the forepart beyond a position in which the leveling roll is located substantially at the junction of the forepart and shank, which means Vis adjustable to vary the extent of such rearwardmovement in accordance with variations in length of the foreparts of shoes of different sizes and styles. As herein illustrated, the movable stop is connected to the shoe support in such manner that its initial position relative to the above-mentioned plate is varied in aoco-rda-nce with variations in length of the foreparts of shoes of different sizes in response to adjustment of the shoe support to accommodate shoes of different sizes. The connections are further such that they may be adjusted independently of the size adjustment of the shoe support to cause the movable stop to be moved relatively to the plate at diierent rates of speed to vary the extent of rearward movement of the support in accordance with variations in length of the foreparts of shoes of different styles.

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

Since the invention is illustrated as applied to a leveling machine of the type fully shown and described in the above-mentioned Letters Patent, 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. It will be understood that the machine includes in its organization a shoe support or jack I8 to which swinging movements are' imparted b-y power-operated means, under control of the operator, to carry the shoe rearwardly and forwardly beneath a leveling roll I2 which is yieldingly forced down on the shoe bottom to apply leveling pressure progressively to the sole and to which tipping movements may be imparted by other power-operated means, also under control of the operator, to cause leveling pressure to be applied to the margins of the sole. The jack Iii (Fig. l) comprises a toe post I4 and a heel post IS which are pivoted together at I3 for relative adjustment for shoes of different sizes by means of a threaded rod 28, which moves the heel post toward or from the toe post so that the toe ends of shoes of different sizes will be presented initially in substantially the same 75 relation to the roll I2. The toe and heel posts are provided with means for supporting a last and shoe for the leveling operation, comprising an adjustable toe support 22 carried by the toe post I4 and a spindle 24 carried by the heel post i8, the spindle extending through an enlarged opening in a plate 26, also carried by the heel post, which plate is free to tip about an axis extending laterally of the shoe to adjust itself to the top face of the heel end oi the last. The roll I2 is mounted for turning movement on a rod 28 carried by a holder 38, which is pivotally connected at 32 to a carrier 34 mounted for tipping movements laterally of the machine about the axis of a forwardly and rearwardly extending shaft 38 supported by bearings at the top of the frame of the machine.

In the illustrated machine the rearward and forward swinging movements of the jack I8, as a whole, about the axis of the shaft I8 and the tipping movements of the roll I2 laterally of the shoe are effected by power through the action of fluid-pressure means, which is not herein shown in detail since it may be and preferably is substantially like that fully shown and described in the previously mentioned Letters Patent. Brieiiy, the huid-pressure means comprises two iiuid motors 48 and 42 (Fig. 1), the motor 48 being connected to the jack I8 by means of a pinion 44, the teeth of which mesh with segmental teeth 45 formed on an arm 48 integral with the toe post I4, and the iiuid motor l2 being geared to a shaft 58 on which there is fast an arm 52 having pivotally connected to it an upwardly extending adjustable rod 54 pivotally connected at its upper end to an arm 55 on the carrier 34. As fully disclosed in the above-mentioned Letters Patent, the machine is provided with valve mechanisms, one of which is shown at 58 (Fig. 1),that are movable in opposite directions by means of hand levers 68 and 62 respectively to control the flow of fluid to and from the upper and lower ends of the motors 48 and 42 and thus to control the direction of swinging movement of the jack I8 and the direction of tipping movement of the roll I2. Connections are provided between each motor and its associated valve mechanism for moving the valve mechanism to closed position to stop the swinging movement of the jack or the tipping movement of the roll when the movement of its associated hand lever is stopped, the construction being such that by means of the hand levers 68 and 62 the operator may control the direction and extent of swinging movement of the jack and of tipping movement of the roll as well as the speed of such movements.

Formed on the holder 38 is a rearwardly extending arm 64 (Fig. 1) connected by a short link 66 to the rearwardly extending arm 'B8 of a bell-crank lever 'I8 fulcrumed at 'I2 to the carrier 34. The bell-crank lever 'I8 has a pair of downwardly extending arms 14, carrying trunnions 'I6 extending into a circumferential groove 18 formed in a bushing 88 that is slidably mounted on the shaft 36. Pivotally mounted on a laterally extending shaft 82, supported by suitable bearings in the frame 84 of the machine is an upwardly extending arm 86, the upper portion of which is forked to straddle the bushing 88, the arms of the forked portion carrying trunnions 88 extending into a circumferential groove 98 in the bushing 88. Mounted on the shaft 82 is a downwardly extending yoke 92 and connected to this yoke by a threaded rod 94 is a yoke-shaped member 06,'bet'ween the arms of which at their lower ends there is pivoted alever 98. The lever 08 has oppositely extending arms of equal lengths to the ends of which are pivotally connected abutments |00, |02 for relatively heavy expansion springs |04, |06. At its upper end the spring |06 bears against an abutment |08 pivoted at II'0 to the frame 84. The spring |04 at its upper end engages an abutment ||2 pivotally connected to an arm I|4 integral with the arm 86. It will be evident that the springs |04, |06 tend to swing the arms H4, 86 in a clockwise direction, as viewed in Fig. 1, to cause the sleevel 80 to be moved rearwardly on the shaft 36 and thus to impart downward swinging movement to the holder 30 to lower the leveling roll I2, the initial position of which is determined by the engagement of the arm 86 with an adjustable stop, illustrated as a screw ||6 threaded in the frame 84. The screw H6 is preferably so adjusted that the leveling roll I2 is maintained initially in a position lower than that which it occupies in operating upon the shoe and is lifted at a predetermined time in the rst rearward swinging movement of the jack to prevent interference between the roll and the toe end of the sole. For thus lifting the roll I2 there is provided a plunger H8 and connections therefrom to the arm 86 for swinging the arm in a counterclockwise direction (Fig. l) against the resistance of the springs |04 and |06. As shown, the plunger I I8 is connected to the rearwardly extending arm of a lever |20 which is pivoted intermediate between its ends to a bracket |22 secured by screws |24 to the frame 84. The lever |20 has a forwardly extending arm to which there is pivotally connected an upwardly extending adjustable rod |26, connected at its upper end to an arm |28 integral with the arm 86.

For operating the plunger ||8 to swing the lever |20 and the arms |28 and 86 in the direction to raise the leveling roll I2 to a level higher than the bottom of the shoe, there is provided a fluid motor |30 (Fig. l) not herein shown in detail since it may be, and preferably is, substantially like that shown in the previously mentioned Letters Patent. In the illustrated machine the operating fluid, supplied by a pump, is maintained initially under a predetermined low pressure by means o f a control valve indicated generally by the reference numeral |32, the control valve being held open by the pressure of the fluid against the resistance of a spring (not shown) to permit excess fluid to return to a reservoir in the base 85 of the machine. Y operating fluid, however, is sumcient at this time to impart rearward swinging movement to the shoe-supporting jack but insuicient to operate the fluid motor |30 to raise the leveling roll I2 against the resistance of the springs |04 and |06. As the shoe-supporting jack is swung rearwardly to carry the toe end of the shoe toward the leveling roll I2, the control valve spring is compressed by the swinging of a pair of toggle links |34, |36 (Fig. l) into substantially parallel relation in response to the forward movement of a horizontal rod |38 which is slidably mounted in the frame 84 and is moved forwardly to thus operate the toggle links by means of a spring |39 (Fig. 2) in response to the rearward movement ef the jack to carry the toe end of the shoe toward the leveling roll. Compression of the control-valve spring causes the pressure of the operating fluid to be increased sufliciently to operate the fluid motor |30 to raise the plunger |I8 The pressure of the and, through the above-described connections, to swing the arm 86 in the directionto lift the leveling roll I2. Pinned to the rod |38 is a collar |40 (Fig. 2) and loosely mounted on the rod is a second collar |42, to which there is pivotally connected the downwardly extending arm |44 of a lever |46 pivotally connected to the casing of the fluid motor |30. The lever |46 is connected by links |41 to a valve stem |48. The construction is such that after the toggle links |34, |36 have been moved into a substantially straightened condition in response to the forward movement of the rod |38 and substantially at the time in the rst rearward movement of the jack when the toe end of the shoe is directly under the leveling roll I2, the lever |46, in response to continued forward movement of the rod |38, is swung by engagement of the collar |40 with the collar |42 in the direction to impart downward movement to the valve stem |48 to close a valve (not shown) and thereby to disconnect the fluid motor |30 from the source of pressure fluid to cause the leveling roll |2 to be released to the action of the springs |04, |06 for downward movement into engagement with the bottom face of the shoe at the toe end. Swingingvv movement of the toggle links |34, |36 into a substantially straightened condition is limited by engagement of an adjustable stop screw |50 (Fig. 1), carried by the link |34, with a bracket |52, and continued forward movement of the rod |38 thereafter is permitted by reason of the compression'of a spring |53 (Fig. 2) on the rod |38 through which the toggle links are swung into substantiallyA parallel relation. At its forward end the rod |38 is pivotally connected to an arm '|54 (Figs. 1 and 2) which is fast to a shaft |56 fulcrumed in the frame 84. Fast to the shaft |50is an upwardly extending arm |58 (Fig. l) Carrying a'roll |60 that engages a downwardly extending arm |62 on the toe post I4 of the jack. Forward moveinent of the Irod |38 is limited by the engagement of a pin I 64 carried'by a rearwardly extending arm |66 adjustably secured to the shaft |56 with an adjustable rod |68 at the upper end of a lengthwise slot |10 in therod, the rod being pivotally connected at its lower' end to a treadle |12 which is fulcrumed at I'14`te the base 85. A spring |16 (Fig. 1) tends t6 uphold the treadle |12 with an adjustable screw |18 in the treadle in engagement with a portion f the base 85.

A'springv |80 (Fig. 2) connected at one end to a pin (not shown) projecting from the frame 84 and at the other end to an upwardly extending arm |82 of the lever |46 tends to swing the lever in aA direction to impart upward movement to the valve stem |48 and to hold the valve controlled thereby normally epen with the fluid motor |30 connected to the source' of pressure fluid. In the course of the operation of the machine, with the rod |33 in its forward position and with the above-mentioned valve closed, the operator may by depression of the treadle |12 move the rod v|38 'rearwardly far enough to release the .lever |46 to the action of the spring I 80 without moving the toggle links |34 and |36 into nonparallel relation, thereby causing the above-mentioned valve to be opened and themotor |30 to be connected to' the source of pressure fluid to cause the lifting of `the leveling roll I2 from engagement with the shoe.

For purposes of the presentl invention, the illustrated machine is provided with means for automatically terminating the movement ofthe jack I in a rearward direction in operating on the Iorepart and in a forward direction in operating in the shank, each time in the movement of the jack when the leveling roll |2 is located nearly at the junction of the forepart and shank portions of the shoe bottom. This means comprises, as herein shown, a forwardly and rearwardly extending horizontal rod |84 (Fig. 2), slidably mounted in bearings in the frame 04 and connected to the jack I0 to move therewith. The rod |84 carries a pin |88 which is arranged by engagement with the forward edge face |83 of a plate |90 which acts as a shoulder or abutment to limit rearward swinging movement of the jack and by engagement with the rear edge face |92 of the plate which serves as a shoulder or abutment to limit forward swinging movement of the jack. The connections between the rod |84 and the jack l0 comprise a sleeve |04 slid ably mounted on the rod between a collar |96 pinned to the rod and a second collar |98 adjustably secured to the rod. Pivotally connected to the sleeve |94 is a block 200 through which extends the rear end portion of a forwardly extending rod 202, the rod 202 being held against endwise movement relatively to the block 200 by nuts 204 threaded on the 4rod and engaging the opposite end faces of the block. At its forward end the rod 202 is pivotally connected to a block 200, which is movable on a substantially vertical guideway 208 formed on a casting 2|0 which is pivotally connected at 2|2 to a block 2|4 loosely mounted on a reduced median portion of the threaded rod and held against movement lengthwise of the rod 20 by collars 2|`|1` pinned to the rod and engaging the opposite end faces of the block 2|4. Extending through the block 206 is a threaded rod 2|8 rotatably mounted in the casting 2|0 and provided at its upper end with a hand wheel 220 for turning it to move the block 206 along the guideway 208 and thus to vary the position of the block 208 relatively to the block 2|4. At its lower end the casting 2|0 is pivotally connected to an arm 222, which is pivotally connected at 224 to the heel post l0 of the jack.

The rod 20 has left-hand and right-hand threaded end portions engaging trunnion blocks on the toe and heel posts I4 and I8, respectively, and formed on the forward end of the rod is a head 225 for turning the rod to adjust the heel post toward or from the toe post to accommodate the jack for different sizes of shoes. It will be understood that the block 2|4 will be located substantially midway between the toe and heel posts in all positions of adjustment of the heel post. As the jack is swung rearwardly to carry the toe end of the shoe under the leveling roll and then farther rearwardly to cause the roll to operate along the bottom of the forepart of the shoe, the sleeve |94 will act by engagement with the collar |98 to impart rearward movement to the rod |84 until the pin |80 engages the forward edge face |88 of the plate |90, thus limiting the rearward movement of the jack; the arrangement being such that when the pin |86 thus engages the plate |90 the roll |2 will be located substantially at the junction of the forepart and shank portions of the shoe bottom. Thereafter the jack may be swung forwardly,

y the rod |84 moving forwardly with the jack by reason of engagement of the sleeve |94 with the collar |98, and again rearwardly while the roll |2 is operating on the forepart; after which the operator may, by means hereinafter described,

move the pin |86 out of operative relation to the plate |90, to permit the jack to be swung rearwardly beyond the position determined by engagement of the pin with the edge face |88 of the plate and thus to bring the shank portion of the shoe into position beneath the leveling roll. With the pin |86 again in operative relation to the plate |90, the jack may be swung forwardly and rearwardly while the roll |2 is operating in the shank, the limit of forward movement of the jack being determined by engagement of the pin with the rear edge face |92 of the plate |90. By reference to Fig. 2 it will be seen that the adjustable collar |98 on the rod |84 is preferably spaced from the sleeve |94 a distance somewhat less than the width of the pin |86 plus the width of the plate |90, so that the pin |80 by engagement with the rear edge face |92 of the plate will limit the forward movement of the jack While operating in the shank when the roll |2 is located nearly at the junction of the bottom of the shank and forepart; that is, in such relation to the junction of the shank and forepart as to cause the roll to level the sole up to the ball line without obliterating the ball line (Fig. 9).

In operating on shoes of different styles the operator may, ,by turning the hand wheel 220, vary the position of the block 208 relatively to the block 2| 4 and the axis of the shaft I8, about which the jack as a whole is mounted to swing. Since the jack is swung at a uniform rate of speed, by this adjustment the pin |30 may be caused to move at different rates of speed to vary the extent of rearward swinging movement of the jack before the pin |86 engages the edge face |88 of the plate |90, in accordance with variations in the length of the foreparts of shoes of different styles. It will be readily seen that if the shoe is of a style in which the forepart and shank portions are of the same length, the block 206 will be adjusted along the guideway 208 so that its pivotal connection to the rod 202 will coincide with the pivot 2|2 of the block 2|4. For

shoes of different sizes of that style adjustment of the heel post toward and from the toe post will vary the position of the pin |88 relatively to the plate |90 in accordance with the variations in length of the different sizes, since by turning the rod 20 the pin |86 will be moved toward or from the plate |00 substantially half the distance the heel post is swung toward or from the toe post. If, however, the shoe is of a style in which the forepart is longer than the shank portion and the block 200 has accordingly been adjusted t0 carry its pivotal connection to the rod 202 closer to the axis of the shaft I8 than the pivot 2|2 of the block 2 I4 to the casting 2| 0 and thus to cause a greater extent of swinging movement to be imparted to the jack before the pin |86 engages the plate |90, adjustment of the heel post alone toward or from the toe post will not vary the position of the pin |86 relatively to the plate |90 in accordance with variations in the length extensions of shoes of different sizes of that style. This is effected in the illustrated construction by imparting to the casting 2| 0 a swinging movement relatively to the block 2|4 to vary the position of the pin |86 as the heel post is adjusted toward or from the toe post for different sizes. The casting 2 |0 is thus swung by means of the arm 222 which, as previously pointed out, is pivotally connected to the heel post |6 and the casting 2|0, the construction being such that in operating upon shoes of diiferent styles, that is, shoes in which the foreparts are proportionately longer than the shank portions, the position of the pin |86 relatively to the plate |96 will be caried in accordance with variations in the length extensions of different sizes of shoes of each style.

Geared to the rod |84 is a vertically movable rack bar 226 (Fig, 2), connected by a link 226 to one arm of a lever 236 which is fulcrumed at 232 to the frame 84 and is provided with a sec-- ond arm 234 connected by an adjustable rod to one arm of a two-armed lever 238 fulcrumed at 246 to a `bracket 242 which is secured to a bracket 244 in which the plunger IIB is slidably mounted. The second arm 246 of the lever 236 has pivotally connected to it a depending pawl 248 (Figs. 3 and ll) and engaging this pawl is a spring-operated pin 256 in the bracket 242, the pin acting normally to hold the pawl in engagement with a ratchet plate 252 which is vertically movable in a guideway 254 in the bracket 244 and is connected at its upper end to a plate 256 fast to the plunger IIE. A spring 258 (Fig. 2) connected at .one end to a pin 286 in a bracket 262 in which the rack bar 226 is slidably mounted and at the other end to a hook 264 which extends `through a pin 266 in the arm 234 of the lever 236, tends to hold the parts in the positions shown in Fig. 2, with a pin 268 in the rack bar 226 in engagement with a iinished surface 219 on'the bracket 262 and with the pin |86 in a horizontal position and in operative relation to the plate |93. Pivotally connected to the bracket 242 at 212 is a lever 214 (Figs. 2, 3 and 4) carrying an adjustable screw 216 held in adjusted position by means of a nut and locknut 218, The lever 214 has a downwardly extending arm 280, the lower end of which lies in the path of movement of the above-mentioned rod |38. A spring 282, connected at one end to a hook 284 in the bracket 2.42 and at the other end to a pin 286 projecting from the lever 214, tends to swing the lever 214 in a clockwise direction, as viewed in Fig. 2, and to hold the lower end of its arm 26,6 in engagement with the rea-r end of the rod |38.

As previously pointed out, when the jack I6 is swung by power, under the control of the handlever 66, rearwardly from its initial shoe-receiving position, the rod |38 is moved forwardly to straighten the toggle links |34 and |36 and to cause the fluid motor |36 to raise the plunger II8 to elevate the leveling roll I2 into a position higher than it occupies in operating upon a shoe. As the toe end of the shoe/is moved into position beneath the roll I2 the rod |38 is moved farther forwardly to cause the lever |46 to be swung in a direction to close a valve which disconnects the fluid motor |36 from the source of pressure fluid, thus releasing the leveling roll tothe action` of the springs |34, |66 for downward movement into engagement with the shoe bottom, the plunger IIS also moving downwardly at .the same time as the roll I2. It will be understood that as the plunger IIB is moved upwardly to elevate the leveling roll I2, the ratchet plate 252 moves upwardly with the plunger and acts through the pawl 248 to impart clockwise swinging movement to the levers 236 and 236 (Fig. 2). As the lever'236 is thus swung, it imparts lupward movement lto the rack bar .226, which acts to rotate the rod v|84 far enough to move the pin |86 into a substantially vertical position and, accordingly, out ofoperative relation to the lplate |96. It will also be understood that as the rod Uly swung by the spring 282, and in response to thisA swinging movement of the lever the adjustable screw 216, carried by the lever, engages and swings an arm 288 which is pivotally connected at 296 to the bracket 242 inthe same direction. Formed integral with the arm 288 is a second upwardly extending arm 292 carrying a pin 294 that extends intoan elongated slot 296 in the pawl 248. The construction is such that as the arm 288 is swung by the lever 214 the pawl 248 is moved'out of.v engagement with the ratchet plate 252 thus releasing the lever 230 to the action of the spring 253 for reverse swinging movement inacounterclockwise direction (Fig. 2) to lower the rack bar 226 and-to rotate the rod |84 Vreversely to move the pin |86'again into operative relation to the plate |96;

From the above description it will be evident that as the leveling roll I2 is elevated in time relation to the first rearward swinging movement of the jack I6 the rod |84 is rotated by power to move the pin |86into` an inoperative position with respect to the' plate |96, and that as the iiuid motor |36 is disconnected from its source of pressure-Huid to cause the roll to be released for ,downward movement into engagement with the shoe `blottom'the pawl A24,8 is moved out of engagement with the ratchet plate Y262, thus permitting the spring 258 to swing the lever 236 downwardly in a direction to impart downward movement to the 'rack bar v226 to move the pin I86 again into operative relation to the plate |38. When 4tlf-,ie Yroll-is in` engagement with the shoe bottom the rodv|38 yis in its foremost position and the pawl 243 is held (out `of Vengagement with the ratchet plate 252. With the rack Vbar 2,26 and the plunger ||`8 thus disconnected, the height- Wise position of the plunger may vary in accordance with Variations in the heightwise position of the-leveling roll I2, as it operates progressively along-the bottom oftheshoe, without imparting any turning movement to the rod |84. It will be understoodthat at this -time the pin |86 acts by engagement with the plate |96 to'limit rearward `movement of the jack. After the forepart has been properly leveled, the operator may, by depressing the-treadle |12, move the rod |38 rearwardly'far enough to release the lever |46 to the action -of its spring L86 and simultaneously Yto release-the pawl 248 tothe vaction of its spring-operated pin 239 without moving the .toggle links |34, I36-into non-parallel relation. The uid motor |36 will .then raise the plunger vIIB to cause the roll I2 to be .lifted out of `engagement with the shoe 4bottom and vthe pin |36 to be moved `into an inoperative rposition with respect to the plate |96. The jack 7I6 `may then be moved rearwardly far enough to position the shank 'portion Yof theshoe under the roll I2 with the pin 1:86 located Arearwardly of the plate |96. Release of the treadle'ITZ will then permit the rod |38 to move `forwardly .to cause the uid moto-r`|36 to `be disconnected from its source of pressurefluid and the pawl ,24,8 `to be ,moved out of engagement with the ratchet plate 252, .the springs-If64and V|66 then acting to press the roll `|2 down on the shoe bottom, and the spring 258 acting through the lever 230 and the rack bar 226 to rotate the rod |84` reversely to move the pin |86 into operative relation to the plate |90. As previously pointed out, while operating in the shank portion the extent of forward movement of the jack is limited by engagement of the pin |86 with the rear edge face |82 of the plate |80 when the roll I2 is located nearly at the junction of the forepart and shank portions of the shoe bottom.

In order to take care of variations in length of the forepart and shank portions at the opposite sides of the shoe bottom, the edge faces |88 and |92 of the plate |90 are curved lengthwise of the plate to accommodate such variations in the style o-f shoe being operated upon, and means is provided for varying the position of the plate |90 relatively to the pin |86 in response to the tipping of the leveling roll I2. As shown, the plate |90 is secured to a member 300, which is removably secured to a slide 302 by means of a binding screw 304 (Figs. 2 and 5). The slide 302 is vertically movable in a guideway 366 in the bracket 262 and is connected by means of a link 308 to the rearwardly extending arm of a bell-crank lever 3I0 fulcrumed at 3|2 to the bracket 262 (Fig. 2). The bell-crank lever 3I0 has a second arm 3|4 to which there is pivotally connected a forwardly and downwardly extending bar 3|6. At its forward end the bar 3 I 6 is connected by a link 3| 8 to .i

one arm of a bell-crank lever 320 pivotally connected to the frame 84 by means of a shoulder screw 322 (Figs. 2 and 8). The bell-crank lever 320 has an upwardly extending arm 324 carrying a pin 326 to which is connected a spring 328 the opposite end of which is connected to an adjustable hook 330 carried by a plate 332 secured to the frame 84 by the shoulder screw 322 and a cap screw 334 (Fig. 8) Keyed to the previously mentioned shaft is an upwardly and forwardly extending arm 336 (Fig. 6) carrying at its upper end a pin 338 and loosely mounted on the hub portion 340 of the arm 336 is a second upwardly and forwardly extending arm 342 carrying at its upper end a pin 344. The arm 342 is held against movement lengthwise of the hub portion 340 of the arm 336 by means of a collar 346 secured to the hub 340 by a set screw 343. Formed on the opposite side faces of the bar 3|6 are U-shaped bosses 350, 352 (Fig. 6), the boss 350 being provided with a central recess 354 open at its lower end to receive the pin 338 carried by the arm 336 in response to downward swinging movement of the bar 3 I6 relatively to the arm 3|4 of the lever 3I0, and the boss 352 being provided with a central recess 356 open at its upper end to receive the pin 344 carried by the arm 342 in response to upward swinging movement of the bar 3| 6 relatively to the arm 3|4.

Formed on the arm 336 are segmental gear teeth 358 that mesh with a pinion 360 loosely mounted on a shaft 362 supported by a bracket 364 which is secured to the frame 84 by screws 366. The pinion 360 meshes with a second equal pinion 368 which is loosely mounted on a shaft 310 supported by the bracket 364 in parallel relation to the shaft 362. Engaging the teeth of the pinion 368 are segmental gear teeth 312 formed on the lever 342, the construction being such that, when the shaft 50 is rotated in one direction or the other, equal swinging movements in opposite directions will be imparted to the arms 336 and 342. It will be evident that by connecting the bar 3|6 alternately to the arms 336 and 342 Cal a movement m the same direction may be imparted to the plate in response to tipping movements of the leveling roll I2 in Opposite directions. Thus a single plate |90 may be utilized to limit the extent of rearward and forward swinging movements of the jack when the roll is operating on either the outside or inside margins of the forepart and shank portions of both left and right shoes of the same style. For swinging the bar 3|6 about its pivotal connection to the lever 3I0 to connect it to one or the other of the arms 336 and 342 there is provided a hand lever 314 (Fig. 2) pivoted at 316 to the frame and connected by an adjustable link 318 to the bell crank lever 320. When the parts are in the positions shown in Fig. 2, the spring 328 tends to swing the bell-crank lever 320 in a counterclockwise direction and the bar 3 I 6 in a clockwise direction, about its pivotal connection to the lever 3I0, to hold the bar 3|6 in engagement with the pin 344 in the arm 342 at the lower end of the slot 356 in the bar. Accordingly, as the arm 52 is swung upwardly to tip the roll I2 in the direction to operate upon the inside margin of a left shoe, the plate |90 will be moved downwardly a distance determined by the extent of tipping movement of the roll, and as the arm 52 is swung downwardly to tip the roll for operation upon the outside margin of the forepart or shank of the left shoe the plate |90 would be moved upwardly a distance determined by the extent of tipping movement of the roll in that direction. When it is desired to operate upon a right shoe of the same style the hand lever 314 will be swung downwardly to swing the bell-crank lever 320 in the direction to impart counterclockwise swinging movement to the bar 3|6 (Fig. 2) about its pivotal connection to the lever 3I0 until the pin 338 in the arm 336 engages the bar 3 I 6 at the upper end of the slot 354 in the bar. It will be understood that as the bar 3|6 is thus connected to the arm 336, it will be moved out of engagement with the pin 344 to disconnect it from the arm 342, the spring 328 then acting on the bell-crank lever 320 to hold the parts in those positions. Thereafter, as the arm 52 is swung downwardly to tip the roll I2 for operating upon the inside margin of the forepart and shank of the right shoe, downward movement will beimparted to the plate |90, and as the roll I2 is tipped in the opposite direction for operating upon the outside margin of the forepart and shank of the right shoe, the plate I S0 will be moved upwardly.

By reference to Fig. 2 it will be seen that the hand lever 62 for controlling the direction, extent and speed of tipping movement of the leveling roll I2 carries a pin 380, and formed on the hand lever 314 are spaced lugs 362. When the machine is initially at rest, the hand lever 314 may be swung relatively to the hand lever 362, without interference between the lugs 382 and the pin 380, to connect the bar 3|6 to one or the other of the arms 336, 342 for operating upon left or right shoes. If the hand lever 314, however, is accidentally left in an intermediate position, with the bar 3|6 connected to both of the arms 336 and 342, the pin 380 in the hand lever 62 will be located between the lugs 382 on the hand lever 314, and accordingly the hand lever 62 will be locked against swinging movement in either direction to start the tipping of the leveling roll, thus insuring against any danger of damage to the parts. It will of course then be necessary for the operator to swing the hand lever 314 fully into its uppermost or lowermost position to unlock the hand lever 62.

In the operation of the machine, briefly summarized, the operator mounts a last and shoe on the heel pin carried by the heel post I6, adjusts the heel post toward or from the toe post for the size of shoe to be operated upon, rotates the hand wheel 220 to vary the position of the block 205 relatively to the block 2|4 for the style of the shoe and, by means of the hand lever 3M, connects the bar 3|6 to the appropriate arm 330, 35.2 for operating upon either a left or a right shoe. Then by rearward swinging movement of the hand lever 60, the operator causes the jack l to be swung rearwardly to bring the toe end of the shoe under the leveling roll I2. As the jack is thus swung the rod |38 is moved forwardly by the spring to swing the toggle links |34, |36 into substantially parallel relation, thus further compressing the spring of the control valve |32 to cause the pressure of the operating uid to be increased. As the pressure of the operating fluid is increased, the leveling roll l2 is raised by the fluid motor |30 into a position higher than it occupies in operating upon a shoe. In the continued forward movement of the rod |38 the lever |46 is swung, by engagement of the collar |40 on the rod with the collar |02 to which the arm |54 of the lever |46 is pivotally connected, against the resistance of the spring |80 in the direction to impart downward movement to the valve stem |48, thus closing the valve and disconnecting the iiuid motor |30 from the source of pressure fluid. This releases the roll rl2 and the holder 30 to the action of the springs EM and |06, the roll being swung downwardly to engage the shoe initially upon the bottom face of its toe end. Thereafter, the operator may, by movement of the hand levers 60, S2, cause the jack to be swung rearwardly and forwardly beneath the leveling roll, the limit of the rearward movement of the jack with the leveling roll in a horizontal position or tipped any desired angle being determined by engagement of the pin |86 with the edge face |53 of the plate |00 each time when the roll is located substantially at the junction of the forepart and shank portions. After the forepart of the shoe bottom has been properly leveled, the operator will depress the treadle |72 to cause the leveling roll to be lifted from engagement with the shoe and the pin |86 to be moved into an inoperative position relatively to the plate |90., and will, by movementl of the hand lever |50, cause the jack to be moved rearwardly to bring the shank portion of the shoe under the leveling roll. He will then release the treadle |12, whereupon the roll l2 will again be pressed yieldingly down upon the shoe bottom and the pin |85 moved into operative relation to the plate |60. Then, by movement of the handlevers and 62 the operator will cause the roll to operate progressively along the bottom yof the shank portion of the shoe, the limit of forward movement of the jack being determined by engagement of the pin |8 `with the edge face |92 of the plate |90 each time when the leveling roll is located nearly at the junction of the shank and Vforepart; that is, in such relation to the ball line as to cause the roll to level the sole up to that line without obliterating it. At the end of the shank-leveling operation the operator will again depress the treadle l'l2.to permit. the jack to be swung forwardly beyond the position determined by engagement of the pin |85 with the edge face |92 of the plate |00, the, jack being then swung forwardly to its initial position for the removal of the last and'shoe.
