, LASTKNG MACHHNE Arthur Bates, Leicester, England, assignor to United Shoe Maehinery Corporation, Paterson, N. 3., a corporation of New Jersey Application October 1, 1934, Serial No. 746,345 In Great Britain @ctober 28, 1933 36 Claims.

This inventionrelates to lasting machines and is illustrated as embodied in a lasting machine of the type comprising a single gripper operating progressively to pull successive portions of a shoe upper heightwise of a last and to carry the margin of each portion inwardly over an insole on the last bottom, a wiper operating to lay the tensioned portion of the upper against the bottom of the insole, and fastening-inserting mechanism by which each overwiped portion is secured.

When machines of this type are intended. for use in lasting around the toe ends of shoes as well as for lasting along the sides (and it may be also around the heel ends), they are equipped with mechanism whereby the gripper may be given auxiliary movements as it lays the marginal portions of the upper successively over the insole around the toe end of the shoe in order that the marginal portions may be plaited one over the other in compact formation. A machine of this type is disclosed in Letters Patent of the United States No. 584,744, granted June 15, 1897, upon application of Ladd and McFeely.

In using machinesthus equipped, it is usual for the operator to present a shoe to the machine supported in his hands and, when the side portions of the shoe along the shank and along the forepart rearwardly of the toe end are to be operated on by the machine, he holds the shoe across his body andsupports it by grasping the heel endof the shoe in one hand and the toe of the shoe in the other. He is thus well able to support the shoe against the downward thrust of the fasteningdnserting mechanism of the machine as it descends sharply to insert a fastening through a side portion of the upper pulled heightwise of the last and carried over the insolo on the bottom of the last by the gripper. However, when the toe end of the shoe is to be operated on, the operator has to hold the shoe so that its toe end points more or less away from him into the region of action of the last gripper, and, since the downward thrust of the fastening-inserting mechanism, usually a tack driver, then acts on the end of the shoe as contrasted with along the side, it becomes more difficult for the operator to support the toe end of the shoe against the downward thrust of the tack driver, particularly since that one of his bands which is supporting the shoe nearer the 3e end has to be extended well away from his body. 7

It has been observed that, owing to the increased difficulty of supporting a shoe while the as end of its upper is being lasted and tacked in lasted position by a machine of the type referred to, there is a tendency for the downward thrust of the tack driver to depress the shoe somewhat in the operators hands, thereby causing the tacks to beincompletely driventhrough the upper and insole and preventing the overlaid margin of the upper materials around the toe, end from being secured as firmly to the insole as'is desired. Since the successive marginal portions 10, of theupper materials around the toe end are plaited one over the other and since a toe box or toe stiffening member is usually included in the upper materials, the total thickness of the marginal portions of the upper which are laid 15,, over the insole about the toe end is greater than the thickness of the upper materials alongthe sides of the shoe and therefore it is important that the tacks inserted through the upper, and into the insole aroundthejtoe end be clinched 20 as firmly as possible in order to secure the plaited upper materials rigidly to the insole and to hold them as fiat as possible against theinsole, it being understood that the toe end of the last is metal shod to clinch the tacks.

Objects of the present invention are rigidly to support the toe portion of a shoe during the fas-. tening-inserting and preferablyalsothe wiping operations of a lasting machine of, for example, the type above referred to and to permit free 30 manipulation of the shoe in the hands of the operator during the upper-tensioi1ing operations of such machine.

A further object is to avoid interference of the supporting means with the shoe while the sides of the shoe are being lasted. I

A feature of the invention consists the combination, with upper-tensioning. means, upper-'- wiping means and fastening-inserting mechanism, of a support which is maintained yieldingly 40 against the shoe during the upper-tensioning op eration and is held rigidly during the operation of the wiping and fastening-inserting mechanism, Preferably also the support is not only heldrigid- 1y against the shoe to prevent depression thereof, but is urged or crowded toward the shoe during at least the latter partof the wipingoperation and during the fastening-inserting operation so that, in case the fastenings are tacks, the tacks will be fully driven home and clinched against 50, the bottom of the last, thereby securing the up per materialsand the insole together in a very effective manner and also insuring thatthe action of the wiper will beefiective to flatten the lasted upper against the insoleQ r M As a still further feature of the invention, the toe support is arranged to occupy an inoperative position while the side portions of the shoe are being operated upon and may be brought into operative position by the operator when the toe end of the shoe is to be operated upon.

These and other features of the invention will appear more fully from "the detailed description when read in connection with the accompanying drawing and will be pointed out in the appended claims.

1 A machine embodying the present invention preferably comprises a gripper Ii) which operates to grip successive portions of the margin of a shoe upper presented to the machine on a last with its sole face uppermost, to pull them heightwise of the last, and to urge them inwardly over an insole on the last bottom, the shoe being held against the upward pull of the gripper It by a sole rest I21 engaging the bottom of the shoe in the vicinity of the gripper. It will be understood also that, besides the updraw and overdraw movements which are imparted to the gripper, means similar to that disclosedin the patent above referred to may be provided for effecting clockwise or counterclockwise plaiting movements of the gripper and for controlling such movements. As usual also, the machine comprises a main slide l4 arranged to reciprocate horizontally and carrying a wiper l6 which has at its forward end a tack block l8 to which tacks are delivered from a raceway 2G by a tack separator 22 and are driven into the work when the wiper is in its forward position by a tack driver 2 The machine is preferably provided as usual with a hunter or. edge gage 26 positioned beneath the wiper l8 and arranged to occupy a forward operative position when it is to be used, for example,

when working around the toe' end of a shoe, the

' bunter being moved to a rearward inoperative position when it is not required, for example when working along the shank portion of a shoe.

In the present illustrative embodiment of the machine, there is secured below the edge gage 26 a fixed bracket 30 in which is rotatably mounted a pin 32 which extends in a direction from left to right of the machine. To this pin is fixedly secured a toe-rest-supporting arm 34 which 7 has a forwardly extending stem 36 secured in a allow the toe end of the shoe to ride smoothly over it. The tablet is arranged to be pressed upwardly against the under side of the toe end of the shoe while the toe end is being operated upon bythe machine and is able to move in a universal manner onthestem 36 to accommodate itself to the varying contours around the toe end of the shoe. The length of the toe-rest-supporting arm 34 and the stem 36 is such that the toe rest or tablet is positioned somewhat forwardly of the position which the edge gage 2B occupies in working around the toe end of the shoe, so that the tablet bears against the under side of the end of the toe just forwardly of the edge of the shoe and occupies such a position, looked at from above, between the edge gage and the shoe rest that the axis of the tack driver passes substantially through its central portion when the driver is in the position it assumes during the tack-driving operation, thus providing a support for the toe end of the shoe directly on the line in which the tacks are driven into the work.

The toerestsupporting arm 84 has formed on its rear end, rearwardly of the pin 32, a locking segment l-i having a number of ratchet teeth formed concentrically with the axis of the pin 32. When the toe rest is in operative position, the ratchet teeth :28 extend from a position directly below the pin 32 upwardly and rearwardly through an angle of about forty degrees. The pivot pin 32 has also secured to its right-hand end a cam plate 38 which is adapted to be engaged by a cam roll 59 carried by the forward end of a substantially forwardly and rearwardly extending lever 52 which is pivoted substantially midway of its length on a screw 54 threaded into the fixed bracket 3&3. V A tension spring 55 stretched between the rear end of the lever 52 and a pin 58 in the bracket 30 urges the cam roll 58 into firm engagement with the cam plate 48 and causes the latter and also the toe-rest-supporting arm when it is in the operative position shown in Fig. 1, to be urged in a clockwise direction as seen in that figure. When, however, the toe rest is pushed downwardly by the operator and the cam plate 48 thus rotated in a counterclockwise direction as seen in Fig. 1, a point indicated at 6% on the cam surface passes forwardly beneath the roll 58 and the cam plate t8, and the to-e-rest-supporting arm 34 will be urged in the reverse direction by the action of the cam roll 58 on a downwardly sloping cam face 62 on the cam plate until the stem 36 occupies a substantially vertical position determined by engagement of the cam roll 59 with a projection 64 formed on the cam plate 58 and in which position the toe rest will be entirely inoperative, as may be required when lasting the sides of the shoe. An adjustable stop-screw 65 threaded into a downward extension El of the fixed bracket 36 bears at its upper end against a leaf spring 68 fixed to the under side of the cam plate 48 and serves to limit yieldingly the amount of upward movement of the toe rest imparted to it by the spring 55 acting on the cam roll 5d. The leaf spring 68, however, is not of sufficient strength to prevent the rest from being crowded toward the shoe by means other than the spring 55, which means will be hereinafter described.

Rotatably mounted on the pin 32 at the right of the toe-rest-supporting arm 34 is a'downwardly and rearwardly extending arm 73 which carries at its lower end a pawl 32 which is adapted to engage the ratchet teeth it formed on the segment '24. The arm it has formed therein substantially midway of its length (Fig. 3) a rectangular opening is in which is positioned a cam or eccentric it formed on the left-hand 'side of a'downwardly extending arm 18 rotatably mounted on a pin 80 secured in the downward extension of the bracket? 38-, said pin extending toward the left from the extension 67..

Thep-awl i2; is rotatably mounted on an eccen' tric portion 85!. at the left-hand end of-a pin 84 which is iournaled a. bore in the lowerend of the arm-l@. 'I'he opposite endof the pin 84 has fi-xed to it a shortdepending arm 85 which has a flat face 88 adapted to be engaged by a roll 9t carried by the lower end of the downward- 1y extending. arm. '58. A tension spring 92 stretched: between apin on the pawl 12 and the bracket 33 tends to urge the pawl 12 a clockwise direction into engagement with the ratchet teethyit. A second tension spring 94 lying by the side of and to the right of the spring 92 is stretched between a hook 96 in thedepending'arm 85 and the bracket 3! andacts to turn the arnitt and thus the short pin 84 in a clockwise direction. This, due to the action of the eccentric 82 on which the pawl 12 is mounted, serves to take up any lost motion that might.

be presentbetween the pawl 12 and one of the ratchet teeth at. Thus wherever the pawl engages the toothed segment the space between the end. of the pawl and the toothnext to the left will be first taken up by the spring-operated eccentric 82 and, since any practicable pressure of the pawl against a tooth would be insufficient to turn the eccentric 82, the lever 10, eccentric 82,, pawl 72, and segment 44 form an unyielding connection to the toe support 42 whatever its operative position maybe, in which connection there is no lost motion or backlash.

Since it is desirable to be able to move the shoe freely as it is shifted to a new position at the end of each cycle of the machine, means is provided to withdraw the pawl 12 from engagement with the ratchet teeth 36 at the end of each cycle. This means will now be described.

The downwardly extending arm 18 which is pivoted on the pin 3t haspivoted to it substan tially midway of its length the lower end of'an upwardly extending rod 98. The upper end of this rod is pivoted to a forwardly extending arm of a bell crank lever ltd pivoted on a stud I62 fixed to the machine frame. An upwardly extending arm of the bell-crank lever liiii has pivoted to it the forward end of a short, rearwardly extending rod iii-i which passes through a trunnion Hi secured to the forwardly and rearwardlyreciprocating slide it which carries the tack block id. A spring Hi8 encircling the rod lu l bears at its rear end against the trunnion Hi6 and at its forward end against a shoulder on the rod lid and urges the rod forwardly so that a nut HE; on the rear end of the rod lii i contacts with the rear side of the trunnion it. On the eccentric portion 32 of the short pin a l on which the pawl 12 is mounted is formed a head portion 2 l2 (see Fig. 4) and the rear side of this headed portion H2 has a circumferential slot H4 formed in it which is engaged by a lug H6 projecting into the slot from the left-hand side of the pawl l2. When the short depending arm 85 which is fixed to the right-hand end of the pin 84 has been rocked rearwardly to an angle of some 50 degrees due to the swinging movement of the downwardly extending arm T3,. the lower end of the circumferential slot (it formed in the head H2 will contact with the lug H6 to cause the pawl 12. to move out of engagement with the ratchet teeth 56. By reference to Fig. 1 it will be seen that as the slide it moves rearwardly near the end of the cycle of. the machine to withdraw the tacking mechanism from the shoe. being operated upon the: bell crankv l 00 will be rotated in aclock-- wise direction, as seen inFig. 1, and will cause, through the rod 98, rearward andupward swinging movement of the arm l8. As this occurs the downwardly and rearwardly extendingarm is;

causedby the action of the cam formed on the lefthand side of the arm '18, to be swung slightly toward the rear, thus relieving the. up.- ward pressure of the toe rest on the shoe. Further movement of the arm 18 brings the roll 90 in contact with the face. 88 formed on the short depending arm- 85, causing rotational movement. in a counterclockwise direction, as seen in Fig. 1,, oi-thepin 84 and the eccentric 82 thereon which moves the pawl 12 along the ratchet teeth suflicien-tlyto. enable the pawl 12 to be easily withdrawn from engagement with them, such. withdrawal taking piace when the pin 84 has-been rotated suficientl-y to cause the end of the slot H41 in the headlzlZ of the pin to engage the lug. lit on the pawl Conversely, as the slide [4 moves forwardly the arm 18 is swung in a clockwise direction, permitting the short arm 86 to be swung by its springas in the same direction. The end of the slot H4 is thus moved away from the lug Hfito permit the spring 82 to turn the pawl into engagement with the segment 44 which itengages somewhere between two of the ratchet teeth 46. Further swinging of the short arm- .86 by its spring 94 rotates the eccentric182 to move the ratchet along the segment until such move ment is arrested by contact of the pawl 12 withone of the teeth 46. Pressure of the pawl l2- against the tooth of the segment 44 cannot rotate the eccentric 82 and hence a positive connection without lost motion or backlash is established between the lever Ill and the toe rest 42. Fur: ther swinging of the arm 18 by its yielding connection 98, I20, [$8 with" the forwardly moving slide I4 rotates the eccentric 16 which crowds the lever it (Fig. 3) and pawl '52 in a clockwise direction to apply further upward pressure to the toe rest, during the final portion of the inward movement of the wiper and during the action of the driver 24 to insert a tack. The spring I08 will, or course, yield to permit the slide 14 to complete its movement after sufiicient pressure has been applied to the lever 70 by the eccentric 16 so that the shoe is crowded hard against the wiper it and the reaction of the shoe prevents further rotation of the eccentric I6.

In the operation of the machine the stem 36 which carries the shoe-engaging member or rest 42 will at first occupy an inoperative vertical position, the toe rest being thus positioned well away from contact with the shoe while the side lasting and tacking operations are being carried out along the side portions of the shoe until the sides have been lasted substantially as far toward the toe end. as the ends of the tip line. While the. lasting is being carried out along these opposite side portions, the shoe is held by the operator in the usual way, one-hand supporting the toe end of the shoeand theother hand supporting the heel end. After the sides of the shoe have been lasted the operator will, before he presents the shoe to the machinefor toe lasting, swing the toe-rest-supporting arm 34 upwardly to bring the toe rest 42 into operative position, the operative movement of the arm 34 being limited yieldinglyby contact of the leaf spring 68 with the stop; screw 6.6. The edge gage 26 is moved forwardly into operative position and the operator then holds the shoe up against the bottom rest I! in th e'usual way and slides the. toe end of the shoe over the toe' rest 42 into engagement with the edge gage 26. In doing this the toe rest 42 will be depressed somewhat by the shoe but will be held in contact with it by the spring 56 which tends to lift it by pressing the roll 50 on the cam 48. Having properly positioned the toe end of the shoe for the lasting gripper H] to act on it at the desired. portion, the operator depresses the starting treadle of 'the'machine, whereupon the gripper acts to impart to the'selected marginal portion of the upper a tension heightwise-of the shoe and to carry it over the insole in the usual manner. When the lasting action of the gripper has been completed on this marginal portion the slide M which carries the tack-inserting mechanism commences to move forwardly from its rearward tack-receiving position to carry the tack block I6 and tack driver 24 into their forward positions over the marginal portion of the upper which has been carried over the insole by the gripper ready for the tacking operation. Immediately after the slide 84 commences to move forwardly, the arm 18 which is pivoted'on the pin 80 will be rocked yieldingly in a clockwise direction, looked 25 spring 94. This allows the pawl 12 to be swung into engagement with the ratchet teeth 46 by the spring 92 attached to it and further rotation of the eccentrictz by the spring 94 will take up any lost motion which may exist between the pawl and one of the ratchet teeth. Thus, the toe rest 35 becomes firmly locked against downward movementfrom a position in firm engagement with the shoe-in which it was urged by the spring 56. Continued dropping movement of the arm 18 due to continued forward movement of the slide 14 will cause the eccentric 16 to swing the downwardly and rearwardly extending arm ii! slightlyin a clockwise direction as viewed in Fig. l, and since this arm is firmly locked by means of the pawl 12 to the toe-rest-supporting arm 34 additional upward pressure is exerted by the toe rest on the shoe just before and during the time when a tack is, being driven. Therefore, before the tack-driving operation actually takes place, the shoe not only becomes supported positively against downward thrust but is urged upwardly and becomes firmly clamped between the tack block I G and the toe rest 42, thus causing the overlasted marginal portions of the upper to be flattened still more firmly against the insole and producing a flatter feather on the shoe. The slide l4 carrying the tack-inserting mechanism continues its forward movement after the toe rest has become locked in the manner described and the tack-driving operation takes place when it has reached its most forward position, in which position the tack driver 24% will be directly in line with the toe rest 42. The toe rest remains locked against downward movement until the tack-driving operation has been completed and therefore, when the tack driver 24 actually descends to drive the tack into the work, the toe end of the shoe is supported on its under side'by'the toe rest Aland is thereby held against downward movement by the driver blow so that the full force of the tack-driving operation is available to drive the tack through the upperand insole and to clench it against'the metal plate on the last bottom with which lasts forthiswork are usually equipped. Since the last is 'held'stationa'ry, this clenching will be performed 'in a very effective manner." Since the toe end cannot be moved downwardly under the blow of the driver, the action of the driver will serve more effectively to flatten the upper against the insole as the tack is being driven into the work and therefore the upper becomes secured to the insole while it is being pressed against it under very heavy pressure, thus tending to produce a flatter feather or overlasted margin on the upper. Moreover, as will be readily appreciated, the fact that the toe end of the upper is supported in a positive manner by the toe rest relieves the operator of the necessity of resisting the downward thrust exerted on the shoe by the driver and therefore makes it easier for him to operate the machine.

After each tack-inserting operation has been completed, the slide M carrying the tack-inserting mechanism is withdrawn rearwardly to receive a tack for the next lasting and tacking operation and as it does so the pawl 12 is withdrawn out of engagement with the ratchet teeth it on the toe-rest-su'pporting arm 34 through its conncction'with the tacker slide l t, and the toe rest is restored to a floating condition, that is, a condition in which it is upheld in engagement with the under side of the toe of the shoe yieldingly by the action of the spring 56. With the rest in this condition the shoe is readily movable relatively to the gripper to enable a further portion of the upper to be presented thereto since the rest can rise or fall in contact with the shoe to accommodate itself to variations in the heightwise or transverse curvature thereof. When the next portion of the upper comes to be operated on and just before the slide l4 carrying the tack-inserting mechanism reaches its full advanced position ready for the insertion of a tack, the toe rest again becomes automatically locked against the downward movement from whatever heightwise position it may have reached due to the varying contour of the toe end of the shoe and remains locked until the tack-driving operation has been concluded.
