45 Claims.

This invention relates to machines for operating on shoes or shoe parts and is herein illustrated and described as embodied in a shank reducing machine.

It is an object of this invention to provide an improved feeding arrangement in a machine for operating on shoes or shoe parts. In accordance with a feature of the invention the illustrated machine is provided with a plurality of gages for determining the position of the work piece relatively to an operating tool, in combination with means actuated by the gages to effect a relative movement between the work piece and the tool to cause the tool to perform an operation upon the work piece whenall of the gages have been engaged by the work piece. In the illustrated machine each of the gages has aconnection to a clutch mechanism, which connec tions are constructed and arranged to prevent the clutch mechanism from starting a feeding 20 movement until all the gages are pressed against by the work piece. As illustrated, each of the gages is mounted for a limited yielding movement under pressure of the work piece and the control means connected to the gage is operated by such movement of the gage resulting from the pressure of the work piece. The feed con,- trol mechanism comprises a pair of clutch members normally latched out of engagement with each other and urged into engaging position by a resilient means, the movement of the gages operating to unlatch the clutch members and thereby to start the feeding movement- It has been found convenient in the illustrated machine to arrange certain of the above-men- 35 tioned gages in such a manner that after determining the initial position of the work piece they would, unless moved, remain in the path of feed of the work piece. 7 In accordance with another feature of the invention means are provided for removing the gages from the path of feed, such means being operated automatically by th feeding mechanism at the beginning of the feeding cycle.

It is a further object of the invention to provide a convenient arrangement for adjusting the machine .for operations not only upon. work .pieces of different sizes but also of different styles. In accordance with this object a feature of the invention consists in the provision of a lever connected to a gage to control the position thereof, in combination with means for adjusting theposition of the lever about its fulcrum and with means for adjusting the position of the fulcrum. One of these adjustments serves to position the gage for operations'in accordance with the size of the work pieces, and the other in accordance with the style. The illustrated ma chine is provided with a scale graduated to indicate sizes and a pointer constructed and arranged for manual movement over the range of graduations of the scale and having connections to the gage for controlling the position the position of the gage, the machine being further provided with mechanism operable upon said connections for varying the relation between the pointer and the gage to enable the gage to be adjusted for work of a desired style.

A still further object of the invention is to provide amachine wherein the direction of the rangement for reversing the direction of the I feeding movement of a sole support and with cutting means adapted to operate on soles fed in both directions. The reversible feeding mechanism is driven in one direction from a source of external power and in the reverse direction by a spring. The cutting means consists of a pair of knives having their cutting edges disposed to operate upon a sole fed in opposite directions in combination with means for moving each of the knives between operative and outof-the-way position'according to the direction of relative feeding movement.

I'naccordance with still another feature. of the invention a pair of oppositely disposed gages are, provided for gaging a. sole successively-from the same end to present opposite lateral margins of the sole to an operating means, in combinationwith means for feeding the sole successively in opposite directions. Means are provided for adjusting these gages toward and from each other in accordance with the size of the soles to beoperated on and in addition means are pro- ,vided for adjusting the gages asymmetrically with respect to the operating means in accordance with the styles of work to be performed.

With the above and other objects and features in view the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

Fig. 9 is a section on the line IX--LX of Fig. 2.

In the shank reducing machine herein illustrated, a sole is supported upon a work table l0 in the position indicated by the reference character S (Fig. 3). The toe end of the sole is pressed against a gage I2, the edge of the forepart of the sole is pressed against a gage I4, and the edge of the heel portion of the sole is pressed against a gage Hi. When all three gages are thus engaged by the sole, automatic mechanism later to be described will cause rotation of a lower feed wheel l8 and anupper feed wheel 20. The lower feed wheel 18 operates through a notch in the work table I0. As soon as the feeding movement begins the gage I2 is lowered out of the path of movement of the sole and a shank reducing knife 22 makes a reducing cut in the lateral margin of the sole which terminates when the feeding movement ceases, the extent of the feeding movement being adjustable. The sole is then replaced upon the table Iii in reversed position as indicated by the reference character S (Fig. 3) with the toe end against a gage 24, the edge at the forepart being against the gage l4 and the edge at the heel portion being held against a gage 26. The pressure of the sole against these three gages again starts a feeding movement of the sole, this time in a reverse direction, to cause the sole to be operated upon by a second shank reducing knife 28 (Figs. 1 and 2) disposed in a direction appropriate to the direc tion of feed of the sole. This knife 28, it should be noted, was in an out-of-the-wfay position while the work piece was being fed in operative relation to the knife 22, the knife 22 being removed from operative position and the knife 28 being moved into operative position by mechanism which later will be described.

The supporting structure of the machine comprises several upright frame members 30 (Fig. 2) extending from a base 32 adapted to be secured upon a work bench. The first and second frame members 30, from the forward end of the machine, are reinforced by a bridge 3| (Fig. 3) connecting their upper portions. The work table In has two rearwardly extending lugs 33 which are secured by screws 35 to the forward frame member 33. Pivotally mounted for heightwise movement about a pin 33| (Fig. 2) secured in one of the rearward frame members 30 is a head 34. The pin 33l engages a slot 36 formed in the head 34 to provide for longitudinal adjustment of the latter, such adjustment being effected by a screw 38 (Figs. 2 andS) threaded into another of the frame" members 30 and having a smooth shank portion which turns in an open-ended slot formed 'slot formed in a lug 46 on the head 34. A collar 42 and a head 44 on the screw 38 engage opposite sides of the lug 46 to move the latter as the screw is turned. A pair of bearing surfaces 46 (Figs.

2 and 6) formed on the head 34 are slidably en- I gageable with the corresponding surfaces formed on upstanding portions 48 of the frame member 30 to guide the head in its rising and falling movement about the pin 33L An operating rod 50 (Figs. 2 and 6) which is slidably keyed to the bridge 3| has a horizontal slot 52 (Fig. 2) formed in its upper end to engage a pin 54 extending from the head 34. A compression spring 56 surrounding the rod 56 and interposed between the lower surface of the base 32 and a nut 58 threaded on the rod 50 tends to hold the head 34 down in a stop position which is determined by a screw 60 threaded into the frame 36 and having a head 62 engageable with an under surface formed on the head 34. The head 34 may be raised in opposition to the spring 56 by a lever 64 (Fig. 6) which is fulcrumed upon a pin 66 secured in the frame 30 and which has a forked end 68 which engages a collar ill adjustably secured upon the operating rod 50. The lever 64 is operated through a rod 12 the lower end of which is connected to a treadle (not shown). The feed wheel 20, the

knives

22 and 28 and the forepart edge gage M are all carried by the head 34 and rise and fall in accordance with variations in the thickness of soles being operated upon.

Journaled in the frame 30 is a main shaft 14 (Figs. 2 and 6 to 9, inclusive). Secured upon the shaft 14 isa cam 16 (Figs. 2 and '7) having a peripheral face which, in the illustrated machine, is eccentric with respect to the shaft 14 and which is engaged by a roll 18. A lever having a hub 8| whereby the lever is fulcrumed upon a 'pin 82 fixed in the frame 3|! carries the cam roll 18 at one of its ends and at its opposite end is pivotally connected to one end of a link 84 the opposite end of the link 84 being pivotally connected to an arm 86 extending from a sleeve 88 which, in turn, is mounted for free rotation upon the shaft 14. A longitudinal slot 90 formed in the lever 8!) enables a shouldered pin 92 which constitutes the pivotal connection between the lever 80 and the link 84 to be adjusted at any desired radial distance from the axis of the fulcrum 82. Surrounding the hub 8| is a torsion spring 94 which tends to rotate the lever 80 in a counterclockwise direction, as seen in Fig. 7, thereby holding the cam roll 18 at all times in engagement with the cam 16. The outer end portion of the arm 86 extends over a considerable are about the axis of the shaft 14 and constitutes a gear segment 96 which is in mesh with a pinion 98 secured upon a shaft I00 which is journaled in the head 34. The outer end of the shaft 108 carries the upper feed wheel 26. The lower feed wheel I8 is mounted upon the outer end of a shaft I02 journaled in the frame 30 and movement of the lower feed wheel is transmitted from the upper feed wheel shaft through a pair of gears I04 and I06 secured upon their respective shafts.

Mechanism which will later be described is provided for driving the shaft 14 through a half revolution and then automatically stopping. It is evident from an inspection of Fig. 7 that a half turn of the shaft 74 will cause the cam roll 18 to move from its extreme position toward the right to its extreme position toward the left, causing movement of the lever 80 in a clockwise direction thereby rocking the gear segment 96 in a clockwise direction (as viewed in Fig. 7) and rotating the shaft I 06 and the upper feed wheel 20 in a counter-clockwise direction (as viewed in Figs. 7 and 1) and causing the lower feed wheel to be rotated correspondingly in the opposite direction.

The next half turn of the shaft 14 will enable the spring 84 to move the lever and the parts connected therewith in the opposite direction while the cam roll 18 rides upon the surface of the cam '16. It is apparent, therefore, that during one cycle of operation the feed rolls will operate to feed a work piece in one direction and during the next cycle they will operate to feed in the opposite direction. The length of the feeding movement is'determined by adjustment of the pin 92'toward or from the axis of the fulcrum 82. The outline of the cam 16, which in the illustrated machine is circular and eccentric with respect to the shaft 14, will result in a feeding movement which accelerates rapidly from zero velocity at the beginning and decelerates rapidly to zero velocity at the end, the actual travel of the 'work piece being practically negligible during the periodsof rapid acceleration and deceleration.

The shaft 14 as above mentioned is driven by mechanism actuated by 'the pressure of a sole against the various gages. When a half revolution has been completed the movement stops automatically. The mechanism for thus driving the shaft 14' derives its movement from a pulley I08 (Figs. 2 and 9) loosely mounted on the shaft 14 and driven from any suitable source of power in the direction indicated by the arrow in Fig. 9. Extending from the pulley I08 is a sleeve or hub IIO which carries a cam disk II2, the periphery of which is engaged by a'cam roll H4. The greater portion of the periphery of the disk H2 is circular and concentric with the axis of the shaft 14; there are, however, two diametrically opposite raised portions H6 and H8. The roll H4 is mounted for free rotation upon the end of an arm I20 which is pivotally mounted upon a pin I22 secured in an extension I24 of one of the frame members 30. The arm I20 is urged downwardly by a spring I26 which tends to maintain the roll I I4 in engagement with the peripheral surface of the cam disk I I2. Fulcrumed upon a pin I28 secured in the frame'30 close to the base 32 is an'arm I30 the upper end portion of which is beveled, as indicated by the reference numeral I32 (Fig. 2). Slidably keyed upon the shaft 14 is a clutch member I34 having 'a disk I36 from one face of which extend two raised portions I38 which are diametrically opposite each other and which are beveled to correspond to the beveled surface I32. The disk I36 carries four clutch pins I40 which are parallel to and arranged concentrically around the shaft 14. Raised from the end face of the cam I I2is'a disk I42 having four openings I44 which may be engaged by the pins I40, the leading edges of the openings being beveled as indicated by the reference numeral I45 in Fig. 2. A compression spring I46 constantly urges the clutch member I34 toward the right, as viewed in Fig. 2, urging the pins I40 to a position of engagement with the openings I44 and thereby causing the drive of the pulley I08 clutch member I34 to the shaft 14. The upper end of the arm I30 is normally interposed between the disks I36 and I44 with the beveled surface I32 against! one of the corresponding beveled surfaces of the raised portions I I8, thereby holding the clutch member I34 in open or disengaged position against the forceof the spring I46.

Integral with the arm I30 and extending angularly therefrom is an arm I48 having an end portion I50 which is notched to form a shelf I52. Three depending latches I54, I56 and I56 are I48 occupyingit's normal to be transmitted through the pivotally mounted in s'ide by-side relation'upon a pin I60 secured in an upright portion I62 of the frame, each of which latches has. a notch formed in its lower end which is engageable with the shelf -I52 to prevent upward movement of the arm I48. A tension spring I64 which is weaker than the spring-I26 is interposed between the arm I48 and the arm I20 tending to rock the arm I30 in a clockwise direction, as viewed in Fig. 9. The tendency of the spring I64 to rock the arm I30, however, is normally overcome by the three latches I54, I56 andl58, any one of which is s'uflicient to hold the arm I48 down as long as its notched end engages the shelf I52. Pivotally connectedto the arm I48 is the lower end of a link I66 in the upper end portion of which is formed-a slot I68. Extending laterally from the arm I20 is a pin I10 engaging the slot I68. The length of the link I66 is such as to bring the bottorn ofthe slot I68 substantially into engagement with the pin I10 when the arm I20 is in its low or normal position with the roll II4 on the circular portion of the cam H2 and with the arm latched position as shown in Fig. 9. Pivotally connected to the arms I54, I56 and I58'are links I12, I14 and I16, respectively. These links are connected to the various gage members in a manner later to be explained and operate to disconnect the latches I54, I56 and I58 when the sole or work piece is held against the gages.

Assuming now that, the various gages are thus engaged by a work piece and that the three arms or latches I54, I56 and I58 have all been disengaged from the shelf I52, the tension of the spring I64 will tend to rock the arm- I30 from the position in which it'is shown in Figs. 9 and 2. Nothing can happen, however, while the arm I20 is in its low or normal position because the pin I10 exerts through the link I66 a downward thrust derived from the spring I26 which is more than enough to overcome the upward pull of the spring I64 on the arm I48. As soon as the rise II8 of the rotating cam I I2 raises the arm I20 the spring -I64 will raise the arm I48, rocking the arm I30 in a clockwise direction, as seen in Fig. 9. The upper'end of the arm I30 is thereby removed from between the disks I36 and I44, and the spring I46 will urge the clutch member I34 toward the right into engaging position until end bearing surfaces I18 on the raised portions I38 engage the face of the disk I42. The pins I40 will engage the openings I44 as soon as the latter come into register with the pins and the rotation of the shaft 14 will begin. The continued rotation of the cam disk I I2 will first bring the rise I I8 away from the roll I44, enabling the arm I20 to drop to its normal position. The arm I30, however, will be prevented from swinging in a counterclockwise direction by a bearing surface formed on the inside upper portion of the arm I30 and engaging the periphery of the raised portion I38. Continued rotation of the clutch disk I36 will bring the raised portion I38 away from the upper end of the arm I30 which thereupon will swing into the space between the disks I36 and I44 and occupy its normal position as shown in Figs. 2 and 9. Still further rotation of the disk I36 will bring the beveled surface of the other raised portion I38 into engagement with the bevel I32of the arm I30, thereby wedging the clutch member I34 to the left (as viewed in Fig. 2) and disengaging the clutch. Thelatches I54, I56 and I58, which will have engaged the shelf I52 as soon as the arm I30 swings into normal position, will now serve to hold the arm I30 in normal position until the latches are again disengaged by the pressure of another work piece against the gages.

The

knives

22 and 28, as has already been mentioned. are, mounted for movement into and out of operative position to enable each knife to be suitably disposed in relation to the direction of feed of the work piece. To this end the knives are both carried upon a bracket I (Figs. 1 and 2) which is fulcrumed for free pivotal movement about the upper feed wheel shaft I00. The knife 22 has a rearwardly extending rectangular shank which is secured by a set screw I82 in a block I83 having a cylindrical stem which passes through alined openings in two spaced ears depending from a block I84. A clamping member I85 occupies the space between the above-mentioned ears and has an opening to accommodate the cylindrical stem of the block I83. The member I85 has a rearwardly extending stem upon which is threaded a nut. When this nut is tightened against the adjacent rear surfaces of the depending ears it will draw the clamping member rearwardly and bind the cylindrical stem of the block I 83 securely to the block I84. A clamping screw I86 extending through a longitudinal slot I88 in the block I84 adjustably secures the latter to the bracket I 80. An adjusting screw I90 having a head suitably grooved for engagement with a flange extending from the block I84 is threaded through a lug I92 on the bracket I88. Upon loosening the clamping screw I86 the block I84 may be adjusted longitudinally to provide a heightwise adjustment for the knife 22 by turning the screw I90. The knife 28 is similarly mounted by a block 19!, a clamping member I93, and a set screw I94 to ablock I96. A clamping screw I98 extending through a longitudinal slot 208 secures the block I96 to the bracket I 80. An adjusting screw 202 having a head suitably grooved to engage a flange extending from the block I96 is threaded through a lug 204 extending from the bracket I80. Turning of the screw 202 after the clamping screw I96 has been loosened serves to adjust the block I96 longitudinally and thereby to adjust the knife 28 to a desired heightwise operating position.

Mechanism for swinging the bracket I80 about the axis of the shaft I00 to bring one or the other of the knives into operating position comprises a link 206 pivotally connected at one end to the upper portion of. the bracket I 80 and pivotally connected at its other end to an eccentric pin carried by a disk 288. Journaled in bearings 2I0 formed in the head 34 is a shaft 2I2 upon the forward end of which is secured the disk 208 and upon the rearward end of which is secured a gear 2I4 (Figs. 1, 2 and 8). Meshing with the gear 2! 4 is a gear segment 2I6 formed upon an arm 25 8 of a bell crank member which is fulcrumed upon a pin 228 secured in an upwardly extending portion 222 of the frame 30. The above-mentioned bell crank has another arm 224 which is pivotally connected to the upper end of a link 226 the lower end, of which is connected to an arm 228 of a second bell crank. This second-mentioned bell crank is fulcrumed upon a pin 230 secured in the frame portion 222 and has a downwardly extending arm 232 which carries a cam roll 284. Secured upon the main shaft 14 is a cam 236 having a concentric peripheral cam surface 238 of relatively large radius extending through an arc of nearly and a concentric peripheral surface 240 of relatively small radius diametrically opposite the surface 238 and also extending over nearly 180. A pair of

non-radial surfaces

242 and 244 connect the

surfaces

238 and 240 and render the entire periphery of the cam 236 continuous. The roll 234 is held against the periphery of the cam 238 by a spring 24I which urges the arm 232 toward the left as viewed in Fig. 8. The cam 236 is so arranged upon the shaft 14 that at the beginning of each cycle of movement the cam roll 234 will travel along one or the other of the

inclined surfaces

242 or 244 thereby suddenly rocking or enabling the spring 24I to rock the bell crank 232, 228 between its two extreme positions and thereby moving one of the knives into its operating position while simultaneously moving the other knife to an outof-the-way position. While the knives are performing these movements the feed of the work piece will be so slight, owing to the design and arrangement of the cam 16, as to be negligible.

The gage I4 (Figs. 1, 2 and 3) for the edge of the forepant of the sole has a rearwardly extending shank 246 having a tongue 248 by which it is slidably guided for forward and rearward movement in a groove formed in the bracket I 80. A screw 252 threaded in the bracket I80 and having a shouldered head engaging a slot in the shank 246 retains the tongue 248 in its guide groove. The rearward end of the shank 246 engages a plate 256 formed on the upper portion of a lever 258 (Figs. 2, 3 and 6) which, in turn, is fulcrumed upon a pin 260 extending laterally from one of the frame members 30. The lower end of the lever 258 is pivotally connected to the forward end of the link I14 which, as has already been explained, is one of the three links controlling the clutch mechanism. A tension spring 26I (Figs. 2 and 8) secured to the link I14 and anchored to a lateral extension of one of the frame members 30 urges the link I14 rearwardly. into latching position and urges the upper portion of the lever 258 forwardly or to the left as seen in Fig. 2. When a sole is pressed against the gage I4 the pressure of the sole against the gage I4 will rock the lever 258 in a clockwise direction, as viewed in Fig. 2, and thereby operate to disconnect one of the three latches which hold the clutch mechanism in inoperative position. The screw 252 by engagement with the ends of its slot in the shank 24 limits the movement of the gage I4 both forwardly and rearwardly.

Provision is made for moving the toe gages I2 and 24 and the heel edge gages I6 and 26 downwardly out of the path of the advancing sole as soon as the feeding movement begins. This is accomplished by supporting these gages upon mechanism comprising a pair of upper parallel arms 262 (Figs. 1, 2, 3, 6, 7 and 8) and 264 and a pair of

lower arms

266 and 268 which are parallel to each other and also to the

arms

262 and 264. All four of these parallel arms are fulcrumed at their rearward ends for heightwise swinging movement upon pins 265 secured in lateral extensions of one of the rearward frame members 30. The

lower arms

266 and 268 have inward extensions 21I (Fig. 6) having bearing surfaces which are in sliding engagement with bearing surfaces 213 on the frame member 30 to guide the arms. All four arms are pivotally secured at their forward ends by pins 261 to lugs 269 extending rearwardly from .a bracket 210 which carries the toe gages and the heel edge gages. It is evident that by reason of this arrangement the bracket 210 may rise and fall without. tilting and without otherwise substantially changing its position. The rising and falling movement of the bracket 216 is controlled througha bell crank 212 (Figs. 2, 3 and 6) fulcrumed upon a pin 214 secured in the frame 36. One arm of the bell crank 212 carries a roll 216 which engages a slot 218 formed in the upper The other arm of the bell crank 212 arm 262. extends downwardly and carries a cam roll 286 which engages a cam face 282 formed on a disk 284 which, in turn, is secured upon the cam shaft 14. The weight of the

arms

262, 264, 266 and 268, together with the parts carried thereby, holds the roll 286 against the cam face 282. Thecam face 282 has a raised portion 286 which at the beginning and end of a cycle, that is, whenever the cam shaft 14 is stationary, engages the cam roll 286 to hold the bell crank 212 in the position shown in Fig. 2 with the gage carrier'arms raised. As soon as the shaft 14 beginsto rotate, the roll 286 will drop from the raised portion 286, enabling the gage carrier bracket 216 to' drop and lower the gages out of the path of feeding movement of the work piece.

The heel edge gages I6 and 26 consist of armate plates having straight work-engaging edges and secured by clamping screws 281 (Fig. 3) upon

brackets

288 and 296, respectively, said brackets being fixed upon the opposite ends of a transversely extending shaft 292 (Fig. 6) which is journaled'in bearings 294- formed on the upper rearward extensions 269 of the bracket 216. A slot 293 (Fig. 2) is formed in the forward frame member 36 to accommodate the up-and-down movement of the shaft 292. The clamping screws 281 passthrough arcuate slots 289 in the gages to provide for securing the gages in any desired position of angular adjustment, the centers about which the arcs of the slots are taken lying in the straight work-engaging edges. Extending downwardly from the shaft 292 is an arm 266 the lower end of which is pivotally connected to the link I16. A spring 291 (Figs. 2 and 8) urges the link I16 rearwardly to latching position and also urges the gages I6 and 26 forwardly. It is evident that the pressure of a sole against either of the gages I6 and 26 will rock the shaft 292 and will cause the link I16 to unlatch one of the three latches which hold the clutch in inoperative position. A stop lug 36I (Fig. 2) extending rearwardly from the bracket 216' and engageable with the lower end portion of the arm 296 limits the rearward movements of the heel edge gages under pressure of the work pieces.

The toe gages I2 and 24, as has already been mentioned, are carried by the heightwise movable bracket 216 and are supported by an ad justing mechanism which is directly mounted upon the bracket 216 by a pair of pins 268 (Fig. l) and 366. This mechanismcomprises'a pair of

parallel arms

362 and 364 having their lower ends pivotally mounted upon the

pins

268 and 366, respectively. 'The'upper ends of the

arms

362 and 364 are pivotally connected to a link 366 at points which lie ina line parallel to a line connecting the centers of

thepins

268 and 366. Pivotally connected to the

arms

364 and 362 between and in parallel relation tothe link 366 and the line joining the centers of the pins 366 and 298' is a'bar 368 which carries a pair offulcrum pins 3I6 and 3I2. Fulcrumed upon the pin 3I6 is a bell crank comprising an arm 3| 4 and an arm 3 I6. A similar bell crank comprising an arm 3| 8 and an arm 326 is .fulcrumed upon the pin 3I2. 'A pair of levers 322 and. 324 which 322 is pivotally mounted anupstanding link 326,

the upper end of which carriesa fulcrum pin 328 of a bell crank comprising, a pair of arms 336 and 332., The arm 336 is pivotally'connected to the upper. endof the arm3l6, being parallel to the lever 322'whi1e the link 326 is parallel to the arm 3I6. Upon the upper 'end of the arm 332 is a plate which constitutes the toe gage, 24. On-rthe outer end of the lever 324 is pivotally' mounted an upstanding link .334 the upperend of which carries a pin 336 which con-- stitutes a fulcrum for a bell crank comprising a pair of arms 338'and 346. The link'334 is parallel to the arm 326and the arm 338 is parallel 344 adjustably limits the degree of separation Which-the spring 346 is able to effect between the lug 342 and the extension-344. A similar .lug 356 extending from the opposite end of the rod 368 constitutes an abutment for one end of a compression spring 352, the opposite end of which bears again-st the under surface of an extension 354 of the link'334. A screw 356 passing loosely through an opening in the lug 356 and threaded into the extension 354 ,adjustably limits the degree of separation which can be effected by the spring -352 between the lug 356 and the extension354. F

Threaded upwardly through the freefinner ends of the

levers

322 and 324 respectively are abutment screws 566 and 562."'A'plate 564'(Fig. 5) having an under'surfacewhich'is engageable by the upper ends of the screws 566 and 562 is carried upon the freeforward end of an arm 566 which is fulcrum'ed upon "a horizontal pin 561 mounted in the bracket'216f 'The arm 566 has a tail 568 which extends'rearwardly' through an opening in the bracket 216 and then downward- 1y, and'which is connected'at its lower end'to the forward end of thelink I12. A'tension spring 5I6 (Figs. 2 and 8) urges the link112rearwardly to a latching position.

The operation of 'the'toe gages as'so far described will now be explained; The'arms 326 and 3I6 are stationary for any given setting of an adjusting mechanism later to be described. Assuming now that the toe end of a sole pressedagainst one of the toe gages, for example the gage I2, the result will bea'rotationof the bell crank 346, 338 about its pivotal connection to the stationary arm 326. "Il're-spring"352 will yield under the downward thrust of the link 334 and the lever 324 will rotate in a counterclockwise'direction, as viewedin Fig. 1,; always remaining parallel to the arm- 338. The extent of actual movement of the gage-I2 will be slight,

The mechanism for adjusting the toe gages for soles of different sizes and styles will now be described. Pivotally mounted upon the pin 300 is a sleeve 358 from which an arm 360 extends upwardly. The upper end portion of the rod 360 constitutes a pointer 362 and is provided with a knob 364 to facilitate swinging the arm 360 about the pin 300. Secured upon the forward edge of the work table is an arcuate plate 366 upon which are formed graduation marks to indicate adjustments of the pointer 362 for various sizes of soles to be operated upon. Extending from the sleeve 358 is another arm 368 the outer end portion of which is pivotally connected to and constitutes one of the supports for an upright member 310 the intermediate portion of which is laterally offset to avoid interfering with other portions of the mechanism. The upper portion of the member 310 is pivotally connected to one end of an arm 312, the other end of which arm is pivotally supported upon a pin 314 secured in the bracket 210. It is evident that by reason of this arrangement swinging movement of the pointer 362 will cause the arm 368 to raise or lower the member 310 while the arm 312 will always maintain the member 310 in substantially upright position. Pivotally mounted upon and depending from an elongated pin 313 secured in the upper end of the member 310 is an arm 316 upon the lower portion of which is formed a pointer 318. Carried upon a forward extension 319 of the lower end of the memher 310 is a plate 380 upon which are formed scale markings to indicate various style adjustments for the pointer 312. Formed in the lower portion of the arm 316 is a closed longitudinal slot 382 Within which is slidably mounted a block 384. Threaded through the block 384 is a screw 386 having a knurled head 388 and a collar 390 spaced from the head. A bracket 392 which is pivotally mounted upon a pin which constitutes the pivotal connection between the arm 368 and the member 310 has an upstanding lug 394 which engages the smooth shank of the screw 386 between the collar 390 and the head 388 to prevent endwise movement of the screw. It is evident that turning of the head 388 will adjust the pointer 318 in relation to the scale graduations on the plate 380. It will be noted that these scale graduations extend from each side of a zero mark which lies in the line joining the centers of the pin connecting the arm 368 to the member 310 and the pin connecting the arm 316 to the member 310. These style adjustments, as will be explained later, will be of the same magnitude for right and left shoes but will be on opposite sides of the zero mark. Accordingly, the pointer 318 can be shifted for right and left shoes merely by the operator grasping a knob 396 extending from the block 384 and rotating the bracket 392 in a clockwise direction, as viewed in Fig. 1, until the block 384 engages the lower end of the slot 382', causing the position of the pointer to be reversed in relaliliOIl to the zero mark.

The connections for controlling the position of the gages l2 and 24 by means of the

pointers

362 and 318 comprise a bracket 398 (Fig. 2) secured by two screws 400 (Fig. 1) to the inner surface of the arm 316. The inner end of the bracket 398 slidingly engages a vertical guideway formed by a pair of parallel-flanges 402 formed on a plate 404 (Fig. which is rigidly secured upon the link 306. Confined between the arm 316 and the inner portion of the bracket 398 are a pair of coaxial cylindrical swivel blocks 406 and 408 each having an end face bearing against the other. Bearing pins M0 and M2 extending from the opposite end faces of the

blocks

406 and 408, respectively, and journaled in suitable openings in the arm 316 and the bracket 398 serve to center the pins for rotary movement independently of each other. The

blocks

406 and 408 are diametrically bored for sliding engagement with a pair of rods 4M and M6 respectively, the rods 414 and M6 being extensions of the bell crank arms 3l8 and 3M respectively.

The operation of the toe gage adjusting mechanism will now be described. The setting of the pointer 362 for size adjustments will raise or lower the member 310 bodily and with it the arm 316 carrying the bracket 398. The two bell crank

arm extensions

400 and 402 will thus simultaneously be rocked in opposite directions about their respective fulcra, causing the arms 3I6 and 320 likewise to rock the toe gages simultaneously in opposite directions about their respective fulcra. Thus, for a large size sole, the pointer 362 will be swung to the left, as seen in Fig. 1, causing a relative separation of the toe gages. This adjustment, it will be observed, will be effective regardless of the position of the style pointer 318. Having adjusted the toe gages for size the operator then proceeds to turn the knurled head 388 to adjust the pointer 318 to a desired style. Such movement of the arm 316 will operate through the bracket 398 to swing the link 306 to the right or left, as the case may be, thereby swinging the

arms

362 and 304 in the same direction and shifting the toe gages l2 and 24 through their supporting mechanism bodily and in unison to the right or to the left. The

pointers

362 and 318 are in suificient frictional engagement with their respective scale plates to hold the mechanism in adjusted position even when a sole is pressed against either of the gages l2 and 24 with a force sufficient to operate the driving clutch.

In the operation of the machine a sole is placed upon the work table and introduced between the feed wheels I8 and 20 in the position indicated by the reference character S (Fig. 3) with the toe end of the sole against the gage l2, the edge of the sole in the vicinity of the ball line against the gage l4 and with the edge at the heel end against the gage IS. The sole chosen for purposes of illustration is an outsole intended for the right foot, the tread or grain surface of the sole resting upon the work table and the flesh surface being uppermost. When the sole has been pressed against the three gages above mentioned they will yield slightly and, when they have yielded to their limiting positions, will gage the sole accurately in relation to the knife 22, it being important that the beginning of the cut to be made by the knife 22 be accurately gaged from the toe end of the sole. As soon as all three gages have yielded under the pressure of the sole against them the feeding mechanism will begin to advance the sole in the direction of the heel end and the knife 22 will make a shank reducing cut from the position indicated in Fig. 3 and terminating at the end of the feeding movement the extent of which is determined by the adjustment of the pin 92 in the slot 90 (Fig. 7) However, the exact point at which the cut terminates is unimportant and the operator may release the sole by hand when, in his judgment, a suflicient length of out has been made. It should be noted that at the beginning of the feeding movement and before the sole has been advanced any appreciable distance the gages l2 and I6 are automatically lowered out of the path of travel of the sole. The sole may now be replaced in reversed position upon the work table I0, as indicated by the reference character S with the toe end of the sole against the gage 24, the edge of the sole in the vicinity of the ball line against the gage l4 and with the edge of the sole at the heel end in engagement with the gage 25. The operation is now repeated to form a shank reducing out upon the opposite lateral margin of the same sole. The cut this time will be made by the knife 28 which will have been automatically swung into operating position at the beginning of the feeding movement. The operator now swings the knob 396 (Fig. 1) toward the right, reversing the pointer 318 to adjust the gage mechanism for left soles and proceeds in the manner outlined above to present the corresponding left sole to the machine.
