A machine of the type in which the invention is herein shown as embodied is provided with a shoe support 2 (Figs. 1 and 3) comprising a post 4 which is slidingly mounted for upward and downward movements in a. casting 6 mounted for forward and rearward swinging movements about a shaft 8 near the base of the machine. The post l carries a block it which supports the heel end of the last and which is provided with a pin 12 arranged to enter the usual spindle hole in the last, the block being movable relatively to the post in such manner as to permit the last to tip laterally. The post also has fast thereon a forwardly extending bar M on which is mounted for adjustment in directions lengthwise of the shoe a bracket is provided with a, toe rest 18 for supporting the shoe under its toe end. At its lower end the post 4 is supported by a rod 20 extending upwardly from a rack bar 22 the lower end of which rests initially on the front end of a short lever 2s pivotally mounted between its ends on a downward extension of the casting 6. By means of a link 25 the rear end of the lever '24 is connected to a treadle 28. Initially the post 4 occupies a forwardly inclined position to receive a shoe, as shown in Fig. 1, and prior to the starting of the power operation of the machine the operator swings it with the casting 8 rearwardly by hand to carry the heel end of the shoe to a position under a holddown 30, this Swinging movement being limited by engagement of the heelehd face of the shoe with a member 32. The operator then depresses the treadle 28 and thereby moves the post 4 upwardly to carry the bottom of the heel end of the shoe into engagement with the holddown 3G and to press it against the holddown, after which he starts the power operation of the machine by rearward movement of the usual starting member 33 (Fig. 1).

Near the beginning of the cycle of operations the machine automatically assumes control of the shoe support 2. For this purpose a slide 34 (Fig. 3) guided in the head of the machine is moved in a rearward direction against the resistance of a return spring 35 by a pinion 36 engaging rack teeth thereon, the pinion being operated by a bell-crank lever 38 provided with a roll 39 engaged by a face cam 42 formed on the rear end of a cam member 45 fast on a cam shaft 46. Other rack teeth on the slide 34 are in engagement with a gear sector 58 formed on one arm of a bell-crank lever 59 mounted on a shaft 52. The other arm of this bell-crank lever is connected by a link as to a pawl carrier 56 mounted to turn about a shaft 58 on which are also rotatably mounted a ratchet wheel 60 and a pinion 62 connected thereto. The pinion is in engagement with a rack bar 64 which is pivotally connected at its front end to the casting 6. A pawl 66 on the pawl carrier 56 is arranged to engage the ratchet wheel 60 and thereby to force the shoe support 2 in a rearward direction in response to rearward movement of the slide as to cause the heel end of the shoe firmly to engage the member 32, the pawl serving thereafter to lock the shoe support against forward movement. Initially the pawl is held out of engagement with the ratchet wheel 60 by a normally stationary pawl controller 68 which releases it to cause it to engage the ratchet wheel at a time in the movement of the pawl carrier 58 variably determined by adjustment of the controller about the shaft 58.

By its rearward movement the slide 35 also operates mechanism which assumes control of the shoe support 2 with respect to upward and downward movements. This mechanism includes a pinion '16 fast on the shaft 8 and engaging teeth on the rack bar 22, and a ratchet wheel 12 also fast on the shaft and arranged to be engaged by a pair of pawls It mounted on a pawl carrier 15 which may turn on the shaft. Connected to the pawl carrier is an upwardly extending rod 18 which has fast on its upper end a tubular casing 89, and slidingly mounted in the upper end of this casing is a rod 82 connected to the bell-crank lever 58. On the lower end of the rod 82 is a disk 84 in engagement with the lower end of a compression spring 86 confined in the casing 38. It will thus be seen that in response to rearward movement of the slide 34 the bell-crank lever 59 acts yieldingly through the spring 86 and the pawls M to apply upwardly directed force to the shoe support and to hold it against downward movement. Initially the pawls Mi are held out of engageemnt with the ratchet wheel i2 by a pawl controller 88 which by its adjustment about the shaft 8 determines variably the time in the movement of the pawl carrier 16 when the pawls are caused to engage the ratchet wheel.

For wiping the margin of the heel-end portion of the upper materials inwardly over the insole, the machine is provided with a pair of wipers 90 which are operated by mechanism constructed substantially as shown and described in Letters Patent No. 2,001,782, granted on May 21, 1935 on an application of J. C. Jorgensens. As more fully disclosed in Letters Patent No. 1,852,015, granted on April 5, 1932 on an application of J.

. C. Jorgensens, these wipers are provided respectively with arcuate rearward extensions 92 and 94 (Figs. 3, 4 and 8), the extension 94 on one wiper overlapping the extension 82 on the other wiper and both extensions being held between two

clamp members

96 and 98 which have tongueand-groove connections therewith. The two clamp members are secured together and to a forwardly and rearwardly movable slide Elli) by means of a screw I 02. The wipers are accordingly guided for swinging or closing movements I widthwise of the shoe about an axis located substantially where their wiping edges meet. The slide 100 is operated to advance the wipers bodily lengthwise of the shoe by a groove cam 104 formed in the cam member 45, the cam engaging a roll M6 on the slide.

For imparting to the wipers their swinging or closing movements in time relation to their advancing movements, there are mounted in guideways in the opposite sides of the head of the machine slides I08, one for each of the wipers,

move'd forwardly to advance the wipei's length- "wisef oi the shoe' the slidesi Q3- are moved inwardly t'oimpart closing movements tothe wipers by the' action" of the -plates IIIv onthe rolls l I4 carried" by-the wipers; the rolls at the same time advancing alongthe slots I I2.

The arm 224 is connected by a link 2l2 to the lower end of an arm 2 (Fig. 2) which is mounted at its upper end to swing about the previously mentioned cylindrical member M8 (Fig. 4). Also mounted to swing about this member is a bellcrank lever 2l6 having a rearwardly extending arm 2l8 through which extends a hollow rod 222 connected by a link 222 to the arm 2 M. Mounted in the hollow rod 226 is a spring 224 seated at its upper end on a screw 226 threaded in the rod, and surrounding the rod is another spring 228 seated at its upper end on a nut 236 on the rod. Upon movement of the bell-crank lever 2P5 in a counterclockwise direction with reference to Fig. 2 a pin 232 carried by the arm 218 of the lever acts either through the spring 224 alone or through both

springs

224 and 228 combined, depending upon an adjustment, to swing the arm 2M in the direction to impart forward movement to the pad 32 and the shoe and thus to insure that the portion of the lip at the rear end of the insole will be close against the holddown plate I65. It will be understood that one or both springs will yield when engagement of the holddown plate with the lip prevents any further forward movement of the shoe. The spring means thus provided for transmitting force from the bell-crank lever 23% to the arm 214, including provision for the above-mentioned adjustment to render one or both springs efiective, is of the same construction as means shown for a different purpose in Figs. 28 and 29 of Letters Patent No. 1,583,044 which may be consulted for a better understanding of details. The operative movement of the bell-crank lever 216 is effected by a face cam 232 on the cam member 44 in engagement with a roll 236 on the lever, the roll being held at all times against the cam by a spring-pressed pin 231 mounted in the head pf the machine and engaging a lug 238 on the ever.

The mechanism operated by the cam 42 for controlling the shoe support 2 not only presses the shoe firmly up against the holddown plate I65 near the beginning of the cycle of operations, as hereinbefore described, but also, by reason of the shape of the cam, forces the shoe more firmly up against the wipers after the wipers have wiped the upper inwardly over the insole to increase the pressure of the wipers on the overwiped portion of the upper. To facilitate such increase of pressure of the wipers on the upper the holddown 30 is so controlled as to permit it to be forced upwardly by the shoe at this time. For this purpose a portion. of the member I10 of the holddown is in the form of a vertically extending rack bar 239 (Fig. 3) in engagement with gear teeth 240 which are formed on a shaft 2 extending widthwise of the shoe and rotatable in the head of the machine. Also formed on this shaft are gear teeth 242 (Fig. 9) in engagement with rack teeth 24 formed on a slide 246 which is mounted for forward and rearward movements in the head. Extending rearwardly from this slide is a rod 248 provided at its front end with a pin 250 which extends through slots 252 in the slide, the front end of the rod lying in a recess in the slide between the slots. At its rear end the rod 248 is threaded in a block 253 pivotally mounted on the lower end of an arm 254 which is mounted at its upper end on a pin 2-56 on the head. Surrounding the rod 248 is a spring 258 confined between the rear end of the slide 246 and nuts 260 on the rod. This spring is under compression and holds the rod and the slide 246 normally in the relation to each other as shown in Fig. 9 with the pin 25!! at the rear ends of the slots 252. Pivotally mounted at 262 on the. arm 254 is a triangular plate 264, a rearwardly extendin portion of which is arranged to engage a shoulder 266 on the head of the machine and a downwardly extending portion of which is engaged by a screw 258 threaded in the arm 254. In this manner rearward swinging movement of the arm is positively limited. A spring 218 in engagement with the front end of the slide 245 tends to move the slide and the rod 248 in a rearward direction and thereby holds the arm 254 at all times in the position determined by the plate 254 and the screw 258. When the shoe is forced upwardly as above described to increase the pressure of the wipers on the upper the holddown is forced upwardly by the shoe against the resistance of the spring 258, causing the slide 256 to move relatively to the rod 248 as permitted by the slots 252 in the slide. The spring is of such strength as to prevent upward movement of the holddown until the time in the cycle when the pressure of the wipers on the upper is thus increased. That is, it prevents upward movement of the holddown when the operator moves the shoe support upwardly by the treadle 2s prior to the starting of the machine and when the shoe is pressed more firmly up against the holddown by the cam 42 near the beginnin of the cycle prior to the operation of the wipers on the upper. Insurance is thus afforded that the shoe will be at the proper height for the wipers to wipe the upper inwardly. It will be evident that the screw 258 serves as convenient means for varying the initial height of the holddown.

The manner of operation of the machine will now be briefly summarized, with reference especially to the chart (Fig. 7) which illustrates the relative timing of different operations. On this chart the line A has reference to the automatic control of the shoe support, the line B to the operation of the Wipers and the line C to the operation of the pad 32. The operator mounts a shoe on the shoe support when the latter is in its lowered and forwardly inclined position, in which it is shown in Fig. l, and swings the support rearwardly by hand to carry the heelend face of the shoe into engagement with the pad 32 which serves as an abutment to limit the swinging of the support. By the treadle 28 he then raises the shoe support to carry the bottom of the heel end of the insole into engagement with the holddown plate I66, the shoe being so positioned lengthwise by the pad 32 as to insure sufiicient clearance between the plate and the portion of the lip a on the insole located at the rear end of the insole. While thus holdin the shoe against the pad and the holddown plate the operator starts the power operation of the machine by rearward movement of the starting member 33. Immediately after the starting of the machine, while the operator is still controlling the shoe support, the pad 32 is moved forwardly by the cam-operated mechanism shown in Figs. 2 and 6 to thrust the shoe in a forward direction and thereby to seat the portion of the lip at the rear end of the insole firmly against the holddown plate I66, the shoe support moving forwardly with the shoe. When the shoe can 9 be moved --no farther for-wardly by reasomof -en-= gagement-of the lip with=the holddowmplate any 1 further movement of the bell-crank lever 2 l 6 r'esults in compression of one-or both o'f the-springs= 224; -22B.- Immediately .thereafterthe team 42 causesthe pawl-and-ratchet mechanisms "shown' in Fig. 3 to assume control of the-shoe supportthe pawl I 68 looking the support against forward-'- movement the pawls '14 lockirig-=it againstu downward movement while pressing the shoe lo more firmly up=-against the holddown plate Thereafter the wipers 'a're' advanced and closed to wipe the margin of the upper=materials inwardly over -the -feather=-of -the *insole and -to if press a portionof themargin'in upstanding po sitionagainst the 'lip of the -insole which-is sup-- ported by the holddown-plate againstthe' inward pressure- 0f the wipersrAfter' -the wipers have*-- completed theirinward movements, a short rise on the cam 32 serves, as indicated-0n"the chariz to "apply additional -*upw-ardly directed forcethrough-the spring 86 and'the paW-ls14 to th shoe supportand thus 'to force the 'shoemore firmly up 1 against the wipersto increase the pressure'of the wipers on the upperheightwise of the shoe.*- By such" upward "movement as -the -s-hce*--" receives in this operation,- accompanied by 'up-= ward: movement of the pad 32 andthe block #90 by reason of engagement of the shoe with the"' padythe holddown is lifted againstthe resistance- 3Q of the spring 258 (-Fig'. 9) *wh-ich'up to this point in thecycle has not yielded-:- =-It will-be e-viderit thatas the increased upWard-lydirectedforce is thus applied-to the shoe support-the 'pawl- 66 acts also to force the'heelend of the shoe morefirmly backagainst the pad 32.
