T 0 all whom it may concern:

Be it known that I, BERNHARDT J ORGEN- SEN, a subject of the, King of Denmark, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Shaping Uppers Over Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes for shaping uppers over lasts, and in many of its aspects has reference more particularly to pulling-over machines.

One important object of the invention is to provide a pulling-over machine adapted for use in the manufacture of a type of shoe commonly known as an arctic shoe or an overshoe. The characteristic shoe of this type has a cloth upper faced round its lower margin with a band of rubber, and a rubber sole which is united by vulcanization to the rubber portion of the upper materials. a In the process of manufacture the upper is lasted over an insole of unvulcanized compound, which may be channeled round its edge to receive the overlaid margin of the upper, and after the lasting the outsole is laid and the shoe is vulcanized. The upper materials, as assembled on the last prior to lasting, present an unusual lack ofconformity to the contour of the last, this condition being due in large measure to the practice of cutting the entire forepart of the fabric upper in a single piece. Such an upper, when assembled on the last, tends to bridge in a marked degree from the toe. end to the cone of the last with a consequent displacement fromthe edge of the last bottom of the margin of the upper along the sides of the ball and in the shank. The difficulties in presenting such a shoe in position to be engaged properly by the grippers of pulling-over machines as heretofore constructed, and the failure of such machines to pull and secure the upper satisfactorily in conformity to the contour of theforepart of the last particularly overthe instep, have necessitated heretofore that the upper pulling: and fastening operations on t p ticu ar p f sh e be peera e by hand.

The present invention provides a machine particularly adapted fer/pulling. over. s which present conditions such asl'hose a ove described. Important features of the invention are to be recognized in a novel" c6 1- Struction and arrangementof upperv pulling and fastening means for. operatingfupon an upper along. the side of the last- 'to. p ull it transversely over the last and secure it in its pulled condition. In the machine. herein shown the upper pulling means at eaoh'sijde of the last comprises two pairsof grippeir jaws with the rear. pair. constructed and arranged'to engage portions of the. margin of the upper at the ball of the last and along the inwardly receding curve of the edge of the last bottom at the rear end o'f'theball, this pair of gripper jaws being curved in,- ward laterally of the shoe along "said inwardly curved edge and also having their outer or lower edges inclined in substantial conformity to the slope of the bottom surface of the last from the ball line rearwardly. The grippers, moreover, are so positioned that the rear pair of jaws project initially fartherv downward than the front pair. As thus constructed and arranged, the grippers are positioned conveniently for the reception of the marginal edge of the ermeatin when the wbrk is presented to the machine, notwithstanding abnormal downward displacement of the margin of the upper. along thesides of the last relatively to the plane of the shoe bottom, and by reason of the construction and arrangement of the rear grippe'r jaws the upper is pulled comparatively close to the lateral surface of the last at the rear end of the ball as well as farther forwardly and in the overdrawing operationof the grippers is pulled tightly inward over the receding curves of the last at the rear of the ball. .Still further to insure that the machine shall operate to pull and conform satisfactorily to the contour of the last the comparatively wide section of upper material extending over the instep, the gripper operating means herein shown is so constructed that the rear pair of gripper {awe at each side receive a longer upper pu ling movement than the front- In order to retain the advantage secured by pulling the upper as above described, the upper fastening mechanism of the machine is constructed and arranged to drive a tack at each side of the shoe substantially at the rearend of the ball of the last in addition to tacks driven farther forwardly. To insure that the rear fastenings shall be properly located to hold the upper where the edge of the shoe bottom curves inwardly toward the shank, the rear tackers are arranged to be positioned by engagement with that part of the shoe where said edge curves inwardly, and a further feature of the invention is to be recognized in the construc tion and arrangement thus provided.

It is contemplated that an organization embodying some or all of the features above jsetforth will have important advantages in themanufacture of other typesof shoes as: well as of the type described. In the manufacture of various kinds of shoes, including welt shoes, it has been found practically necessary heretofore, in order that the upper may be properly stretched and conformed to the lastover the instep and so positioned in the shank as to permit the side lasting machine to operate upon it with the best results, to supplement the pulling-over operation as performed by the pulling-over machine by mounting the shoe on a spindle and pulling the upper at or near the rear end of the ball on eachside of the shoe with hand pincers beforethe shoe is presented to the side lasting machine. The present invention, by its provision in a pulling-over machine of means for pulling and for fastening the upper in the manner above described, eliminates the need for this supplemental manual pull and permits theshoe to be presented directly to a machine .for lasting the shoe along the sides. I

Associated with the upper pulling and fastening meansin the machine shown is an improved construction and arrangement of overlaying means whereby the margin of the upper is pressed inwardly over the insol and properly positioned and held for the reception of the upper fastening tacks,

and further. important features of the invention are to be recognized in the combinationthus provided and in detalls of the overlaying mechanism. An advantageous novel characteristic of the construction illustrated consistsin provision for relative yield of overlaying memberswhich are arranged to operate in different ocations along the edge of theshoe bottom, or example at opposite sides of a fastening point, to insure eflectiveness of the different members notwithst'andlngvariations in contour of the bottom of the last. Sucha construction is of particular util ty where the different members are arranged as shown to operate, one

atthe ball of the last, and the other over the receding curve of the portion of the shoe bottom at the rear of the ball, the provision for relative yield permitting these members to operate with equally effective results to hold the different portions of the upper prior to the tacking. A further ac vantageous characteristic consists in provision for relative adjustment of the overlaying members, permitting the rearmost member, for example, to be positioned initially lower than the member which operates farther forwardly to insure its effectiveness over a relatively lower portion of the bottom surface of the inverted shoe at the rear of the ball line. The provision for relative adjustment of the different members also involves advantages in. adapting the machine for operation upon shoes of different sizes and of different materials.

he above and other features of the invention, including also a novel construction and arrangement of fastening mechanism, and certain details of construction and combinations of parts will now be described with reference to the accompanying drawings and pointed out in the claims.

Fig. (i is a plan view showing one side portion of the shoe as it appears after the upper has been pulled over and fastened, and illustrating further the relation between the shoe and the different operating instrumentalities.

The invention is herein illustrated as incorporated in a well-known type of pulling-over machine, characteristic features of which are shown and described in detail in various prior United States Letters Patent including particularly Patent No. 1,029,387. granted on June 11, 1912 upon an application of R. F. McFeely, and in view of such prior disclosure the present description Will be limited to such details-of the general organization of the machine as it is necessary to refer to for an understanding of the invention.

For pulling the upper atthe toe end of the last the machine has a toe gripper comprising jaws 2 curved andextended for engagement with a considerable portion of the margin of the upper round the toe end of the last, these jaws being mounted on a gripper casing 4 and operated by a gripper bar 6 which is connected to an updraw lever 8. Operative movement is imparted to the lever 8 by means of a cam 16 on a cam shaft 12 througha cam slide 14 and a spring 16 "which forms a. yielding connection between the cam sliue and the rear end of the lever. For pulling the upper at the sides of the last the machine has side grippers the construction of which will be hereinafter more particularly described, these grippers being mounted on gripper bars 18 connected to side updraw lever-s20; The levers 20 are operated similarly to the toe gripper lever 8 by means of a cam 22 on the cam shaft 12 through a cam slide 24 and springs 26. To

support the last against the pull of the grippers in the upper pulling operation the ma chine has a sole rest 28 which is pivotally mounted and is rocked downward slightly by means of a cam 30' during the pulling movement of the grippers to press the last into the upper. A heel rest 32 also is moved at the time of the upper pulling operation into positioning and supporting engagement with the heel end of the shoe.

In the operation of machines of this type the pulling of' the upper by the several grippers is effected in the first stage of the cycle of operations, after which the machine comes to rest to permit inspection of the work and any adjustment which the operator observes to be necessary. When the machine is again started, shoe holding and suportin devices which are mounted on side clamp arms 34 are swung inward into operative relation to the shoe, andeither immediately thereafter, or following a second pause in the cycle of operations, the toe and side grippers are rendered effective to draw the margin of the upper inwardly over the last bottom and the several overlaying and tacking devices are operated to press different portions of the margin of the upper into proper relation to the insole and to fasten them place. The overdraw movement of the toe gripper is effected by overdraw prings36 and the accompanying overdra-w movement of the side grippers by springs 38 3), the inward movement'of these several grippers being controlled by the well-known mechanism provided in machines of the illustrative type as shown and. describedin detail in. said prior patent, The overlaying and tacking mechanism for the toe end of the shoe is mounted upon a front arm 40 and comprises a wiper plate 42 and a tack driver 44, the arm 40 receiving its rearward operative movement from a slide 46 to which the arm is connected. The side overlaying and tacking mechanisms, the construction of which will be more fully described hereinafter, are car 'ied by side arms 48 which are swung inward laterally of the shoe in unison with the rearward swinging movement of the arm 40. The details of the mechanism for imparting operative movement to the arms 40 and'48 and for operating the several tack drivers are not herein particularly illustrated in view of the prior disclosure of said McFeely patent which may be referred to for a more complete understanding of this and other features of the general organization of the machine.

T e side grippers on each side comprise a front Jair of gripper jaws 50 which are arrange to engage the margin of the upper alongthe side of the last near the toe end, and a rear pair of gripper jaws 52 arranged to engage a portion of the upper along the ball of the last, these grippers extending rearwardly a suflicient distance to engage also a portion of the upper at the beginning of the shank. The gripper jaws 52 are curved laterally of the shoe in substantial conformity to the inwardly receding curve of the edge of the last bottom at the rear end of the ball of the last, and as shown in Fig. 2 the outer or lower edges of these jaws are inclined downward similarly to the lengthwise slopeof the last bottom rearwardly from the ball line. The jaws 50 and 52 are mounted respectively on separate gripper casings 54 and 56 to permit relative pulling movements between the front and rear pairs of jaws. that the closing of the jaws is efiected by relative. movement between the gripper casings and the bar 18 assisted by the usual closing springs as the bar is moved upwardly and that in its continued movement the bar operates the gripper casings to cause the grippers to pull the upper through connections including an equalizing lever 58 which permits relative movement between the two casings in response to differences in resist.- ance of the different portions of the upper, this duplex construction and arrangement of gripper operating means being similar to prior constructions as shown and described more in detail in United States Letters Patent No. 1,030,522. granted on June 25, 1912 upon an application 'ofR. F. McFeely. It will be understoodthat initially the grippers are held with the gripper jaws in open condition in consequence of engagement of ears on the gripper casings 54 and 56 with stop shoulders 60 and 62 on a portion of the. frame of the machine. construction the shoulder 62 islower. than the shoulder '60','resulting'in a depression of It will be understood In the present the gripper jaws 52 relatively to the jaws 50, as shown in Fig. 2, to facilitate engagement of the jaws initially with the margin of the upper. In consequence of this arrangement and by reason of the relatively greater yield laterally of the shoe of the portion of the material extending between the opposite pairs of rear jaws 52, due to its greater width and its loose condition on the last, the latter jaws are moved farther than the jaws in the upper pulling operation, the strains being substantially equalized and the grippers coming to rest with the different portions of the upper stretched and conformed with equal effectiveness to the contour of the last.

Portions of the side overlaying and tacking mechanisms carried by the arms 48,

comprising overlaying wipers 64 and 66,

tack holders 68 and 70, and tack drivers 72 operated by a driver bar 74, are similar to the overlaying and tacking mechanism carried by the front arm 40, mechanism of this general type being described more in detailin prior Patent No. 1,029,387 and in Patent No. 1,135,954 granted on April 13, 1915 upon an application of R. F. McFeely. It will be understood that the wiper plates 64 and 66, similarly to the wiper 42 on the front tacker arm, are yieldingly positioned by springs 7 6 (Fig. 1) in such manner as to engage the margin of the upper substantially opposite to the edge of the insole as they move inwardly and then to yield upwardly in their continuedinward movement in response to resistance of the shoe materials, the springs rendering the wipers effective to press the margin of the upper down upon'the insole and to hold it in position for tacking. As illustrated, the tack holder 68 is arranged to hold two tacks in position to be driven at or near the usual tip line location on such shoes as are provided with tips, and the tack holder 7 2 is arranged to hold a single tack in position to be driven asliort distance in the rear of the tip line location. It will be understood that these tack holders and the corresponding drivers are swiveled on their supporting arms for self-adjustment together in the manner explained in the earlier patents in accordance with the lengthwise contour of the lateral peripheryof the shoe, the extent of inward movement of the tacker arms and the consequent distance of the tasks from the edge of the shoe bottom being determined by engagement with stops carried by the underlying side clamp arms 34.

It will be seen by referring particularly to Fig. ,4 that the present machine is prowiper 66, including means for drivinga tack substantially at the rearend of the ball of the last For this purpose each arm48 carries on its rear side a tacker plate 80 mounted on a pivot 78 for swinging movement transversely of the edge of the shoe bottom. The tacker plate 80 carries a tack holder 82 herein shown as constructed substantially as illustrated and described in United States Letters Patent No. 1,279,491, granted on September 24, 1918 upon an application of Orrell Ashton. Associated with this tack holder is a driver rod 84 arranged to be operated by a swinging arm 86 which is pivoted on the plate 80 and slotted to receive a pin 88 projecting from the driver bar 74. A spring 90 connected at one end to a pin 92 on the plate 80 and at its other end to a pin 94 which projects fro-m the bar 48 through a slot 96 in the plate 80 tends to swing the latter plate and its supported tacking mechanism toward the shoe as far as permitted by the pin 94. The tacker plate 80 and the mechanism carried thereby thus occupy initially an abnormally advanced position relatively to the other portions of the side tacking mechanism. As the arm 48 is swung inwardly toward the shoe a stop member 98 on the lower end of the plate 80 is carried into engagement with that portion of the side of the shoe where the edge of the shoe bottom begins to curve inwardly and limits the inward movement of the rearmost tacker, the spring 90 then yielding to permit continued movement of the arm 48 to its limit determined by engagement with the stop on the side clamp arm. The member 98 thus determines the distance between the rearmost tack and the edge of the shoe bottom independently of the other tacking devices, insuring that this tack shall be driven in the proper location notwithstanding pronounced variations in the curvature of the lateral periphery of the shoe. In order to guard against injury to the surface of the upper in the rocking movement of the tacker plate 80 after the member 98 has engaged the shoe, this member in the construction shown comprises a roll for engagement with the shoe materials, the roll being mounted upon a holder 100 secured adjustably by means of screws 102 to the tacker plate 80. By adjustment ofthe holder 100 the member 98 may be positioned to cause the tack to be driven at diiferent distances from the edge of the shoe bottom.

Pivotally mounted on the lower end of the tacker plate 80 below the tack holder 82 are a pair of overlaying members 104 which, in view of their characteristic function, may be conveniently termed wipers, these members in the construction shown having at their front ends rolls 106 to assist in eliminating undesirable friction against the upper at the edge of theshoe bottom. Springs 108 connected to the members 104 and to the pins 92 tend to swing these members abouttheir pivots in a direction for'aptother in response to resistance of the shoe material and in conformity to variations in the contour of the bottom face of the shoe.

The normal position of one of the pair of members 104- is determined by an adjustable e'ccentric stop 110 against'which the member is held by its spring 108, this stop being integrally formed on a stud 112 which project-s through the plate and upon which is mounted an eccentric collar 113' a) for positioning engagement with the other memher 104. A nut 114 on the end of this stud may be tightened to secure the different eccentric members in adjusted position. The provision of these independently adjustable members permits the different overlaying members 104 to be definitely adjusted as desired relatively to th'eplane of the shoe bottom in order to render them equally ef fective, for example, upon the different portions of the margin of the upper at opposite sides of the rearmost tacking point, including a portion overlying the rearwardly sloping contour of the shoe bottom at the rear of the ball. It will be noted by reference to Fig. 5 that the rearmost member 104 is positioned lower than the other member with particular view to effectiveness in operating upo-nsuchportions of the shoe and by reference to Fig. 6 it will be seen thatthis member also projects a little ahead of the other member in view of the inward lateral curve of the edge of the shoe bottom at the rear of of advantage in adapting the mechanism to different shapes of shoes as well as for varying, ifdesired, the overlaying pressures in accordance withdifferences in the condition of different-shoe materials. tackers and their associated overlaying devices are arranged to operate substantially upon the portions of the upper which are pulled by the rear gripper jaws 52 and to drive their tacks in locations lengthwise of theshoe near the rear ends of said jaws.

In the operation of the machine, briefly summarized, the operator presents a shoe with its insole against the sole rest 28 and in the correct lengthwise position determined by the jaws 2 of the toe gripper, andafter arranging the margin of theuppe-r properly within the'open jaws of the several grippers depresses the starting treadle; Immediately following the starting of the machine the several gripper lovers are upraised, causing the gripper jaws to close upon the u per and then to pull it over the last, the pn ling operation of the grippers being accompanied by a slight downward rocking movement of the soleres't effected-by the cam- SO; In this" The rearmost' operation the reargripper jaws 5231B moved each side to cause the upper to be properly pulled and conformed to the contour of the last over the instep as well as farther for} wardly as hereinbefore explained; At the end of the upper pulling operation chine comes automatically to a stop with the upper held under tensionto permit inspection and any necessary adjustment: Following a subsequent starting of the" machine the side clamping and supp orting devices' 34 are swung into operative position, and the toe and side grippers are then released' to the action of their overdraw springsto cause them to pull'the margin of the upper" inwardly over the edge (of the shoe bottom, the inward movement oftheigrippersbeiiigf accompanied by a similarmovementrof the toe and side tacker arms which force the several overlaying members or wiper s into engagement with the tensioned upper and finally trip the grippers to cause them to release their hold upon the stock in theman ner characteristic of machines of this general type. It will'be understood that in this inward movement of the tacker arms the overlaying members are permitted to yield backwardly in responseto resistancejofthe upper held by the grippers,aas well as up wardly, provision for such backward. yield of the members 104 being afforded bythe springs which control the supporting plates 80, and that when the grippers are tripped the several overlaying members are instantly forced farther inwardly as well as downwardlyto prevent the upper fromrelaxi ng before the tacks are driven. The tacker arms having completed their inward movement, and the rearmost tackers' onthe plates 80 having adjusted themselves rela tively to the edge of the shoe bottom, the severaltacks are driven in the mannercharacteristic of machines of this general type, after which the parts return to their starting position and the shoe is released.

It will be evident that the side grippers constructed and arranged asherei'nbeforc described arenot only positioned initially for convenient engagement with the margin of the upper, notwithstanding its abnormal relation to the pla'ne of theshoe bottom in a shoe of the type illustrated, but also serve in the upper; pulling and overdra-wing operations topull theiu'p'per closely over the entire fore part ofthe' last inoluding the instep and to stretch and conform the upper to the contour of the last at the rear end of the ball as} well as farther forwardly. In securing this result the shape of the rear gripper jaws is important, since by substantial conformity to the lateral curve the edge of the shoe bottom as wellas to the 'rearward-sloping ontour of the bottom surface of the last at theire'ar upward farther than'the front jaws on of ball these 'grippers are rendered effective to pull the different portions of the .margin inwardly substantially equal dis tances from the edge of the insole and in equally close relation to'the plane of the insole, thus insuring uniformity in the tightening ofthe upper and" permitting the overlaying members 104 to follow the overdrawn margin closelyand'to clamp and hold it effectually at opposite-sides of the tacking point until the tack is driven. The location of the rearemost tack at or near the rear end of the ball insures that the upper shall be held-closelyconformed to the inwardly receding curve of the last atthe beginning of the shank and shall lie substantially close to theied'geof the insole along the shank in preparation for subsequent.operations.

It will be understood that the invention isby no means limited in utility to the manufacture of shoes of the particular kind herein illustrated, but is applicable to the manufacture of various types of shoes ineluding welt and turn shoes as well shoes of theMcKay type, and to shoes made ofvvarious materials. Followingthe operation of this machine the shoeherein shown maybe presented to a side lasting machine forbVerdrawing and fastening the upper along the shank, as well asto complete the overlaying operation round the toe, or these portions of the margin may be drawn over the edge of the insole and fastened in any other suitable vway, the shoe in any case being in such condition following the operation of the present machine 'as to obviate any necessity for pulling the upper to any substantialextent either in the shank or in anyother part in order to conform it in the desired manner to the contour of the last. It is, contemplated that in the case of welt or turn shoes on some kinds of work the shoe asit leaves this machine will be in such condition inthe shank portion as to permit it tobepresented to a machine such as a sewing machine for securing the upper permanently to the sole or insole without further lasting. Even in cases where it is found desirable to us'e'the side lasting machine on. these or other kinds of shoes, any necessity for pulling the upper at the rear of the ball as a supplementary manual operation is entirely eliminated.

In the appended claims the term sole is used generally for convenience to define that portion of the shoe'to which the margin of the upper is fastened in lasting, irrespective of the type of shoe, and is thus inclusive of the insole of a welt or a McKay shoe as well as of the sole of a turn shoe.
