' tion of machines of this type being -more fully set forth in United States Letters Patent No. 1,029,387, granted on June 11, 1912 upon an application of R. F. McFeely and further, in respect to certain features applicable particularly to the pulling-over and lasting of turn shoes, in Letters Patent No. 1,280,613, granted on October 1, 1918, upon an invention of Orrell Ashton. In view of the disclosure in said patents, only such portions of the illustrative machine as are intimately related to the features of this invention will be described herein in detail.

The machine includes the usual toe grip per comprising jaws 2, a gripper casing 4 on which the jaws are mounted, and a. bar 6 pivoted to an updraw lever 8 which receives its movement from a second lever 9 for operating the gripper. Included also in the machine are side grippers comprising jaws 10, casings 12 and bars 14 connected to updraw levers 16. The

levers

9 and 16 are pivoted on a rod 18 and are operated from a cam shaft 20 through

slides

22 and 24 respectively. Carried by the slide 22 is a rod 26 having thereon a spring 28 which is compressed by downward movement of the rod and thus brings pressure to bear upon the rear end of the toe gripper lever 9 to operate the lever 8 to effect a yielding updraw movement of the toe gripper. The side gripper levers 16 are operated in a similar manner through rods 30 and springs 32.

The shoe is positioned for the operation of the grippers withv its sole on the last bottom in engagement with a sole rest which comprises a foot piece 34 mounted on a slide 36, the slide being adjustable lengthwise of the shoe in a carrier 38 which is pivoted on a shaft 40. Adjustment of the sole rest lengthwise of the shoe is effected by means of a pinion 42 in engagement with a rack 44 on the slide. The carrier 38 is provided with a. roll 46 for engagement with a face cam 48 on the shaft 20, and a spring 50 positions the carrier with the roll in engagement with the cam. In the operation of the machine the carrier 38 is rocked about the shaft 40 by the action of the cam 48 to cause the sole rest to depress the last and the sole thereon within the upper as the grippers pull upwardly.

The machine includes also the usual means for laying the upper over the. margin of the sole and fastening it, comprising side tacker arms'52 and a front tacker arm 54, wipers 56 being mounted on the front arm 54 for lasting the toe portion of the upper; and also included in the machine are the usual pivoted side clamp arms 58 operated from a cam 60 on the shaft 20 through a slide 62 to cause them to engage and hold the shoe for the lasting and tacking operations. It will be understood that the operation of the machine is effected in successive periods or stages, the machine coming to rest with the upper under tension to permit the usual inspection and adjustment and also the positioning of the wipers 56 manually in engagement with the upper, after which, by the further rotation of the cam shaft, the side clamp arms 58 are moved into enga 'ement with the shoe and the lasting and tacking instrumentalities are caused to perform their functions, laying the upper over the margin of the sole and fastening it in position.

For the purposes: of the present invention the illustrative machine is provided with a hold-down for engaging the feather of the sole at the toe end and also with a hold-down associated with each of the side grippers for engaging the feather at opposite sides of the sole. The toe hold-down comprises a plate 64 having a depending lip curved for engagement with the feather of the sole about the toe outside of the upper attaching shoulder or rib, the plate. being secured to an arm 66 which is pivoted at 68. on a slide 70 that extends lengthwise of the gripper bar 6 and the casing 4 and is guided on said bar and casing for movement lengthwise with respect thereto. A spring 7 2 on a rod 74 which projects from the slide 70 tends to position the arm 66 in substantially parallel relation to the slide and the gripper casing with the hold-down member 64 in close proximity to the toe gripper. The arm 66 is provided with a recess 7 6 to receive a projection 78 on the sole rest member 34, and by this construction the position of the toe hold-down lengthwise of the shoe is determined by the sole rest while the hinged connection between the arm 66 and the slide 70 permits the toe gripper to have its charcasing 12 andlis connected, to a second .slide 86 extendingupwardly. along the gripper bar 14. -;The pivotal connection between the plate and the .slide 84 permits the'plate" 3 to' turnon the slide about an axis that ex:

tends laterally; of-thekshoe and thusto bear evenly uponthe sole whatevermay be the.

lengthwise inclinationor contour of the shoe bottom; 1 11; v

2 The operating'means for theseveral hold-v doiwns whereby they are rendered zefiective upon'the soleduring the. upper pulling operation includes-a shaft 88 mounted in bearin'gs in the machine head and provided with 5 crank arms90- and -92.-w-hich :are connected respectively by means ofrods 9,4 to the upper slides 86 of'thetwo side='hold-downs.'

Turnbuckles 96aontthe rods 94-serve to adjust the hold-downs at-difierent distances from the crank arms. "'llhe'toe hold-down is operated from: an-;=extensi0n 98 of the crank arm 90gthrougha rod" 100 which is pivoted to the'slide70 andis adjustable as" to length inthepsaine manner as the rodsi'9.4;: The extension-98 is provided with aslot 102 at difi'erent points :which an ,7 operating. pin 104 may be secured forzimpartingfio the toeihold-down movements varyinginf extent in proportion to, the distance of thepin' from'the' shaft .88. Effective eI'1gagement of the hold-down with the sole may thus be insured, whatever may be the lengthwise curvature of the bottomwof the last. The pin 104 is arranged to move the rod 100.

To this endthe rod as provided with: a projection 108 to"- which is'p'ivoteda link 110 havinga slot 112- which-receives a pin 114onJa' lever 116 'piv-I oted on the frame.

Thelconnection between the-lever 122 and the link 124 comprises a pin 128 which may be "set at different points alongia slot '130in" the lever to vary the extent of the'move merit imparted to'thef shaft 88- from the It will: be evident from the preceding de scriptlon by the downward movement of.

In'order toxwithdraw the hold-downs from. the paths of. movement of the over-1 laying and tacking; devices the, machine'iisprovided with means for-disconnecting the I hold-downs from-a portion ofetheir-operatv ing mechanism and for'retracting them 1 1 mediately prior to :the inward movement; of;

the tacker (1I'II1S'252T' and-154. 'l o this end there is r a ,clutch connection between the;

crank arm 126 and-the 'sha ft-.-88, the crank arm being loosely Imounted; on theashafti and having a pair-of diametrically opposite recesses to receive teeth 132 formedpn-a I clutch hub 1341 which is splined-to'theshatt for sliding movement lengthwisel thereoii and is normallyheld by'a spring 136111; clutching engagement with the crank armg A torsion spring138, anchored'at one. end

to themachine frame and at its otherend m-' a sleeve member 140 on thegshaft 88, tends to turn the shaft inthe direction to upraise the, hold-downs, the member 140 be-:

ing connected to fthenshaft by means of a pm 142 which is mountedin a member 144 secured tothe end, ofythefshaft and enters one of a series of holes inthe member 140* to hold said member in fixed relation .to the member 144. By withdrawing the-pin 142 and: turning the member] 140 :the tension of the spring may be: adjusted. -Whilethe machine is at rest prior to its operation upon ashoe, and during the firststage of the cycle of operations, 'the hub 134 is in clutching engagement with the crank, arm- 126to cause the hold-downs to be depressed] through their connections with thei-rod3l1 simultaneously with the updraw movement of the grippers. In order-to cause-the re-j traction of the hold-downs meansds providedfor withdrawing the hub- 134 fromclutching zengagement with the 'arm1126,

therebyreleasing the shaft 88 from'its con'-.

hold-downs by turning the a shaft. For

sliding the hub 134 in the direction to dis connect it from the; arm 126, the'machine isprovided with a'verticalshatt 146 upon the upper end of which is mounted: a forked? clutch'operating' member 148 having: rolls forengagement with a fiange'on' the :hub 134 to retract the hub against the tension of the spring 136'. The shaft'146'on its lower:

end is provided with an arm 150 arrangedto be engaged by the end of a screw ward movement of the taeker arms.

mounted on one of the arms of a lever 154, this lever being mounted-with its other arm in the path of movement of the slide 62 which, as previously explained, is the means whereby the side clamp arms 58 are moved into engagement with the shoe at the beginning of the second stage of the cycle of operations of the machine. By reference to Fig. 8 it will be seen that the slide 62' has some distance to move before it engages the lever, the parts being so arranged that the clutch is disconnected to release the holddowns just as the side clamp arms engage the shoe and immediately prior to the inadjustment of the screw 152 the time of the release of the hold-downs in relation to the movement of the slide 62 may be varied. A stop pin 156 serves to limitswinging movement of the lever 154 to insure that the lever shall be in position to be operated by theslide 62. In order to avoid excessive shock when the hold-downs'are released under certain conditions, a buffer 158 is arranged in position to be engaged by the arm 92, this buffer being mounted for sliding movement in a socket in the frame against "the tension of a spring 160. A pin 162 serves as a guide for the spring and also to limit the inward movement of the louder 158, the pin being adjustable to vary the limit of the turning movement of the shaft 88 and thereby the limit of the upward movement of the hold-downs.

When the machine is idle and in readiness to receive a shoe, the three hold-downs are positioned in such relation to-the grippers and the sole rest that as a shoe is presented in engagement with the sole rest in proper position for the upper to be seized and pulled by the grippers the margin of the sole is engaged by the hold-downs, and in the case of a turn shoe that portion of the margin which projects beyond the edge of the last.

The toe hold-down 64 at this time is posi-.

first effect of the updraw movement of the

levers

8 and 16 is to cause the grippers to close firmly upon the upper, and until the grippers have thus closed no movement is imparted to the hold-downs by reason of the lost motion'afforded by the slot and

pin connection

112, 114, the pin 114 being positioned about midway between the ends of the slot when the machine is started, as shown in Fig. 1. 'As the grippers begin to pull the upper, the link 110 becomes effective with a downward pull upon the pin 114 and through the connections described begins to turn the shaft 88 forwardly against the tension of the spring138, thereby depressing the side hold-downs substantially simultaneously with the depression of the sole rest 34 which is caused by the forwardly tipping movement of the carrier 38 effected by the action of the cam 48. In other words, as the shoe is depressed by the sole rest, the side hold-downs followthe shoe and remain in substantially continuous engagement with it. The toe hold-down 64, as previously explained, is first positioned closely at the rear of the toe gripper and above the edges of the rearwardly curved gripper jaws, and by reason of this arrangement the lost motion connection, consisting of the pin104 and the slot 106, is provided in order to prevent the hold-down from being depressed immediately at the beginning of the updraw movement of the gripper. The toe holddown may, in fact, be raised slightly by the action .of thetoe gripper as the latter begins to pullupon the upper, affording time for the gripper to clear the hold-downby its characteristic forward swing which is effected in a manner well understood through the action of an abutment 163 upon a cam 164 on the grippercasing 4 as the gripper is pulled upwardly. A further reason for the slot and

pin connection

104, 106 is that the connection to the toe hold-down rod 100 is at a greater distance from the shaft 88 than the connections to the side hold-down rods, and the provision for lost motion in the toe hold-down operating means serves to prevent any tendency to move the toe hold-down too far as compared with the side holddowns. The hinge connection 68 between the gripper casing and the arm 66 permits the toe gripper to swing forwardly while the toe hold-down is retained in substantially the same relation to the sole rest 34 by the engagement of the projection 78 in the recess 76. When the toe gripper is clear of the hold-down 64 the pin 104 becomes effective in the slot 106 to force the rod 100' downward and thus to depress the toe holddown, and in case the margin of the sole has been raised from the last prior to such ence to the last; While the parts are thus '-positioned the operator, after effecting any necessary adjustment of the upper on the .last, advances the wipers 56 into engagement with the upper inthe correct relation for closing movement ,over the margin ofthe sole and releases the toe gripper from en- ;gagement with the upper, as usual in the operation of machines of this type,

When the machine is started a second time to effect the final stage of thecycle of operations, the side clamp arms 58 are first swung inward toengage the shoe by the action of theslide 62,and.the side grippers then move inward over the shoe bottom to can the upper over the margin of the sole, 0 osely followed by the tackerarms 52 which carry the mechanism for laying the upper down upon the margin of thesole at the sides of the shoe and fastening it in position, the side grippers being released from engagement with the upper inthe usual manner by the 7 action of the tacker arms. As the side grippers move inward,,the toe gripper is swung 'rearwardly over the sole by the usual overdraw springs, and simultaneously the wipers 56vare forced inward-by the front tacker arm 54 and are operated by the front'and side arms to wipe the toe portion ofthe upper over the'margin of the sole and tacks are'then driven to secure the overwiped upper in'position. Immediately prior to the inward movement of the tacker arms the slide 62 by'its action upon the arm 154 causes the clutch member 134 to be shifted lengthwise of the shaft 88 to release the shaft from its connection with the crank arm-126, thereby permitting the spring 138 to turnthe shaft and cause the three holddownsto be quickly drawn upward out of the path, of movement of the wipers 56 and .the tacking instrumentalities. The arm 66 of the toe hold-down is thus disengaged from the sole rest 34' and by'the action of the spring 72 it is swung outward toward the toe gripper during its upward movement, such'swinging movement being limited bythe engagement of a projection 166 on the arm with the gripper casing 4 to permit the hold-down 64 to be moved upwardly past the gripper jaws 2 without engaging them. It will-be understood that the toe hold-down, following its upward movement, is carried rearwardly with the toe gripper to make further room :for the overlaying and fastening mechanisms. Since the withdrawing movement ofthe several hold-downs prior to their inward movement with the grippers is away from the plane Of'the sole, there is no tendency to displace the margin by engagement with the shoulder of the sole. Upward movement of the toe holddown relatively to the toe gripper is limited by the engagement .of the upper end of the arm 66 with a lug 168. on the gripper casing, and when the I armarrives in this position the projection 166 enters a recess 170 in the back of; the caslng and permits the hold-down to-resum'e :its original position close behindthe toe gripper jaws. The upward movement of the side hold-downsis limited :byengagement of the slides 84 withlugs 172 on the side gripper casings 12. When the grippers are released from the upper they have a further upward movement under the action of the

springs

28, and 32,- thereby permitwouldresult in such a case if a bufferswere not provided It will beunderstoodthat' before; the machine comes to rest at theend of the final stage of the; cycle of operations; the grippers, tacker arms, clamparms and sole rest are .all returned .to their initial positions. As the cam slides22f and 24 are. moved upwardly theypperate the updraw levers,

to move the grippers downwardly, and by reason ofthe engagement of the lug 168' on the toe gripper casing with the upper end of the arm 66 and 'o'f the projections 172 on the side gripper'casi'ngs withthe slides 84, the hold-downs and their connected slides and operating rods are carried downwardly with thegrippers. During this movement the rods 94 operate the crank arms and 92-to turn the shaft 88 forwardly against the tension of the spring 138. In the meantime the rods 30 and the link 110 move upwardly, and as thepin 11 4 is released by the link 110, a'spring174- which tendsto .turn the crank arm 116-ma counter-clockwise direction causes the -crank arm 126 through its connections withthe-arm 116 to be turned in a direction opposite to the direction of turning movement of the shaft 88;.until the teeth 132 of the clutch member 1334 engage in the recesses in the hub, of the crank arm .126, the clutch member having beenpreviously released through the retraction of the .slide62. When the reengagement of the clutch takes place the grippers are substantially at their limit of ,downwardmovement. The cam slides 22 and 24 however continue to rise-to effect the opening of the gripper jaws and during this final movement the link 110 moves upwardly relatively to the pin 114until-the pin is substantially midway of the length of the slot 112, as shown in Fig. 1. Inthe final position of the parts, moreover, the pin 104 is substantially midway of the length of the slot 106 in the rod 100, this resulting from the fact that the pin 104 moves downward faster than the rod 100 by reason of :the greater distance of the pin from the axis of the shaft 88 as compared with the p ints of connection of the rods 94: with their crank

arms

90 and 92..

As the grippers are returned to their starting positions the toe gripper carries the arm 66 of the toe hold-down into position to effect a reengagement of the projection 78 on the sole rest in the slot 7 6 in the arm. 4 lVhile the novel features of the invention have been explained by reference to a machine particularly designed for use in the manufacture of turn shoes, it will be understood that the invention in its broader aspects is not restricted in applicability to machines for operating upon shoes of this particular type.
