It .Wlll be evident, however, that the inven- -tion in many of its aspects is not restricted to use in themanufacture of felt shoes nor vention provides novel toe lasting means constructed, for the purposes in view, to operate-with less effective pressure upon the stock at the sides ofthe toe than at the end of the toe.
  • the wipers shown are constructed and arranged for operation with diminished pressure atthe sides of the toe, thus rendering them par ticularlyeffective for the purposes in view in the manufacture of a previously side-lasted shoe, as hereinbefore explained.

State of Massachusetts, have inventedcer tain improvements in Machines for .Vfork- 7 ing' Uppers Over Lasts, of which the following description, in connection withthe accompanying drawings, isa specifieationflike 1 reference characters'on the drawings indicating'like parts in the several. figures This inventlon relates to inachlnes for Working uupers over lasts, andmore particularly to machines for performing suchoperations on the end portion of a shoe; The invention is shown here n as embodied 111 a machine having means foi pulliiig an upper over the toe of a last and for working the upper into lasted 11 osition and fastening it at the toe: but it should be understood that the invention, in manyof its aspects is not limited to'a comblnatlonof means forperforming these several operations nor to means restrictedin utility to toe lasting.
a machine adapted-for operation upon the of shoe in which the upper made of felt material. In the manufacture of thistype of shoe it is the usual practiceto out; the upper of sufficient size to permit its lowermarginal portion tobe extended rinward'at the bottom of the shoein. such manner as to serve to a or less extent as an insole a and, before the shoe is mounted on la -last, to. stitch the bottom edges of theoppositem side portions of the upper either directly together or to an insertion of similar material extending for a portion at least of the "distance lengthwise ofthe shoe. Thei'ipper is then dampened and a last:1s inserted to stretch and form the-material in lasted- In accordance with-the usual prac-x "tice and. for the best results the bottom edges shape.
of the material in the toe portion of the shoe tion of the shoe, while damp; is shaped by a toe lasting operation. 1
Specification ofLet ters Patent.
operation of lasting the toe of isuoh. a shoe must beperformed-With *duezregard to the peculiarconditions resulting from the. precedlng steps; in the :manufacture of the shoe, as well asto the character of -the IBERNHARDT aonennsnri; or BEVERLY,
1 material of which: the-shoe is made. "At the 1' rear of the toe'portion wherethe shoe is already slde lasted the upper is stretched across the last, or. laterally to its final shape, and in a less degree'the upper at the sides and over,:the top of the toe, is likewise stretched laterally, by-reason of its connection to the stretched portion atflthe rear.
At thel toeend of the jlastyhowever, the-upper is 111 a substantially unstretched condition, and in lasting the toe it is therefore de-' sirableto pull this; portion of the upper to r some extent over the a last; yThis' operation, however, and also the operation of'laying :the margin of the upper over the bottom of the last,. must be so performed-as to avoid distorting the previouslyfsi de-l asted portion ofthe shoe and also to avoid crowding any portion ofthe unsecured: margin ba'ok over One objectof the invention'isto provide practise heretofore to: gripadifi'erent' portions of the unsecuredcniargin of the upperin succession with hand pincers -an'd to pull eachportion so) grippedand draw it inward a tack tosecure it in lasted position. In origin ofvthelast atfth'e toe, aplurality'ofblows .are then deliueredwvith a hammer. After over the'bottom of-the-last and then todrive' nerto flatten the stoclcdown upon the marwthe stock hasdried and set inpermanentca. and an outsole stitchedi zto the shoe.
The toe lasting operation performed in "the manner above describedis not only-slow but is frequently productive of un'satisfao' toryresults. t is very difficult, in'pulling over and securing diflerent portions of the stock in succession, and particularly in pullshape the tacks are removed, theupstandinged ges of the upper at the toe end are trimmed I r ing the portions at'the sides ofthe toe, to,
effect uniform lasting andto avoichon the one 1 handydistorting; the" previously, sidelasted portions hack? off-the. toe and, on the other 'hancL-iprochicingone on more pleats 0r u'folds in the SlZOCkSOzPI'OIlOllflQQd as to extend out near the edge of the shoe in the portion to which the outsole is to be stitched. Such a fold in the margin near the edge of the shoe is likely to be cut when the upstandingedge of the upperistrimmed off, with a consequent weakening of the portion of the'shoe to which the outsole is to be attached. When the shoe is made of felt, moreover, the strength of the felt material frequently varies in different portions, and for this reason and in view of the dampened condition of the material there isdanger of tearing it by too hard a pull or of rupturingit by the blows delivered over the margin of the last bottom for flattening the margin.
This invention provides a machine which in many respects is'particularly adapted for working over a last the toe portion of the upper of a shoe which' has been previously above referred to, and in this aspect the insidelasted, such as a felt shoe of the type vention affords automatic means for performing rapidly and uniformly an operation heretofore performed in a comparatively slow and unsatisfactory manner by hand. It .Wlll be evident, however, that the inven- -tion in many of its aspects is not restricted to use in themanufacture of felt shoes nor vention provides novel toe lasting means constructed, for the purposes in view, to operate-with less effective pressure upon the stock at the sides ofthe toe than at the end of the toe. Aparticular advantage of a construction embodying this feature, in operation upon-a .shoe previously side-lasted, 1s that the pressure upon dlfferent portions of the stock isproportioned to the different respective'requirements of the end and the sides of the toe, since portions of the stock at the sides of the toe adjacentto the previo-usly lasted portion are already stretched to some extent by reason of theirconnection to the lasted portion and therefore require less overworking pressure. A further important advantage in the use'of such graduated pressure,'.moreover, it that displace- ,ment of the "prev1ously side-lasted portion of the upper'is avoided and the toe lasting is rendered uniform with the side lasting.
- in novel means for working the upper over the bottom of a last round the toe constructed to" operate with acomparatively large component of movement in a direction or diedge of the margin of the upper must be gathered within a comparatively small area .at the toe end of the shoe, and the portions at the sides-of the toe'should be worked inward without overlapping the previously sidelasted portion on the margin of the last. In
line of the shoe-. Advantageouslyalso the wipers shown are constructed and arranged for operation with diminished pressure atthe sides of the toe, thus rendering them par ticularlyeffective for the purposes in view in the manufacture of a previously side-lasted shoe, as hereinbefore explained.
Still another feature of the invention resides in a novel combination of means for pulling an upper at the toe end of a last and for working the pulled upper mto lasted position. As adapted particularly for use in lasting the toes of shoes which have been previously side-lasted, the machine shown is organized to pull the upper at the end of the toe only and to gather and wipe the margin of the upper uniformly inward round the end and along the sides of the toe. ,It is also an important characteristic of the illustrated construction embodying this feature, although .not essential, to the utility of the invention in many of its aspects, that a portion of the marginof the upper of comparatively narrow extentwidthwise of the shoe is pulled back from the toe end over the bottom of the last and that portions of the margin at the sides of the toe are worked inward in such manner as to cause the intermediate pulledback portion to be gathered 'substantiallybe tween the side portions. The novel construction further comprises means for pressing the upper against the toe end of the last to hold it in tensioned condition, permitting the upper to be releasedfrom the pulling means and worked into-lasted position whilev thus held. Preferably the release of the upper iseffected before the wipers become effective to wipe the upper over the-last, thus avoiding such strain upon the margin of the upper at the toe end of the last as might result in tearing the material, particularly in i a shoe made of felt,-an'd atlSQCODtIlbUtlllg to uniform lasting by renderingall portions fof the margin of substantially equal tension A further feature of the invention resides of the wipers is new in'a pulling-over aml lasting machine. I .7
A further feature of. the invention comprises a novel construction of wiper. operat- 111g mechanism including means dependent upon engagement with the shoe for effecting closing movement of the wipers. In the construction shown the wipers are caused to 3 close during their movement lengthwise of lastin g the shoe through the provision of an abutment which engages the end of the shoe and has the further function of holding the upper tensioned to permit the release of thetoe gri per, as hereinbefore explained.
,till another feature of the invention comprises novel mechanism for securing the upper in. lasted position. F or thls purpose the machine shown is constructed. to drive tacks through the marginof the lasted upper and intothelast. If an upper lasted as herei ubefore described is tobe held effectively at the toe without loss of tension, it is desirable that fasteners be driven at the outer sides of the pleats or folds formed in the margin of the materialat the sides of the toe by thela'teral inward-movement of the wipers. In the} use of comparatively thick stock, such'as felt, the folds at the edge of the stock frequently project upward to a considerable distance from the bottom of the last, and in order to insure, that the fastener drivingv means,which is necessarily positioned in close relation to the bottom of the last, shall not interfere with the proper gathering of the material and thus cause the fasteners to be driven in incorrect relation to the folds,jthe invention provides novel mechanism including fastener driving means movable laterally inward at the outer sides of the folds in. the stock into driving position in the correct relation to the folds, the wiper edges being slightly recessed to permit the tack fingers to be positioned far enough outward to avoid interferencewith the folds. The construction shown provides laterally movable tackers with means connecting them to the wipers to cause them to be moved inward with the wipers. I
The above as well as other features of the invention residing particularly in provision for relative adjustment of the wipers and for timing the operation of the wipers, and in certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in theclaims.

The machine in which the invention is shown as embodied includes in its eneral organization many of the features shown and described in prior United States Letters Patent- No. 1,135,950, granted onApril 13,
- 1915, upon an application of'R. F, McFeely, certain of the features of this type ofmachine being described also in greater detail in a prior lS lcFeely Patent No. 1,029,387, granted on June. 11, 1912. In view of the disclosures in these prior patents the present description will be limited, as to the generalorganization of the machine, to such details as it is necessary to refer to for an understanding of the novel features of this 1nvent1on.-
ents, the present machine includes abottom rest 2 having a shoe engaging member 3 which engages theforepart of the shoe stock on the bottom of the last toposition the work for the upper pulling operation, the member being adjustable to determine the plane in which the bottom of theforepart of the shoe-is presented. The machine has also a cam 4: on a cam shaft 6 forrocking the].
bottom rest in a downward direction at the time of the upper pulling operation, a heel rest 8 which is moved upward into supporting engagement with the heel end of the shoe after thetmachine is started, and side a Like the machine shown insaid prior pat-Q- clamp arms 10 which are swung inwardfon opposite sides ofthe shoe into supporting and clamping engagement with the work after the upperpull ng operation has been effected and before the operation of overlayper at the end of the toe-and. operativelyconnected to an updraw lever 14. The lever 114i receives operative movement from a slide 16 operated by a cam 18 on the cam shaft- 6, the connection between the slide and the lever comprising a spring 20 -wliich is compressed to a greater or-lessj extent in proportion. to the resistance of the stock "to cause the gripper 12 to pull the upper'yieldingly. The gripper -12is positioned initially as shown in Fig.1 with the gripper jaws 22 in positionto receive the edge of theupper when the shoe is presented in engagement with the rest 2, the positionof the-gripper lengthwise of the last being determined by a slide 24 provided with a roll in engagement with the rear surface. of the gripperbar to support it against the tension of a spring 26 which tends to swing the gripper rearwardlylf i Atthe front the gripper 12,;tl1e machine is provided with means forlastingthe to secure the mar in of the u er in lasted I t v a osition. T he lastin and tackm means is ular characteristic.

The machine herein shown, like the machines shown in the prior patents above referred'to, is designed to perform itscycle of operations in successive steps between which the machine comes automatically to rest but it should be understood that the invention is not limited to a machine having this partici/Vhen the machine is first started the gripper i2 is caused to engage and pull the upper, and the machine then comes to rest with the upper held un- Upon a subsequent actuation of the starting treadle the side arms 10 are 'SWUDQ' inward ll'ltO supportin en a ement L: ii 0 b 23 with the shoe. lVhen the treadle is depressed again the lasting and tacking'mech-anisms ar e operated to wipe the upper inward over the bottom of the last and secure it in lasted'position', after which the machine is caused to release the shoe and the parts are returned to thelr starting positions.
' The lasting mechanism herein shown comprises wiper plates 32' which are mounted on a wiper support 34; secured by means of a bolt 36 and aunt 38 to thelower end portion of the arm 28. Aslot 40 in the support 34: permits the support to be adjusted "for advancing or retracting the lasting means relatively to the arm 28. The wipers are positioned in overlapping relation and are provided in their adjacent ctaces about an axis which is beyond the end face of the shoe when they are at the limit of their operative movement in order to cause all portions of the wiper edges to receive a substantial component of movement laterally of the shoe during their movement lengthwise of the shoe. In order to cause the wipers'to'operate with eiiective pressure at the sides of the toe part adjacent to'the previously siifle-lasted portion of the shoe, for the purpose hereinbe'fore explained the "front endportions of the wipers on their shoe engaging side are beveled as shown at 45, and with the same object also t-he forepartof the shoe is so positioned by the adjustable bottom rest relatively to thepath of swinging movement of the wipers about the center 29 as to cause the ends ofthe wipers to incline, upward slightly from the plane of the shoe bottom when theyare atthe end of their closing movement.
. in the construction shown the wiper operating mechanism comprises means whereby the arm 28 in it-smovement toward the shoe is rendered efi'ective to cause an operative closing movement of the wipers 32' during their bodily movement lengthwise of the shoe with the supporting arm. For this purpose there is mounted in a .guidevay .in the support 34 aslide 46v to which is secured by-means of a .bolt 48 a bar 50'providedon,
its forward end witha pad 52 for 'engage ment with the toe end face of the shoe. The rearend of the slide 46 is az-rranged to-iengage the inner ends'of a pair oi levers 54- which are fulcrumed on studs-56 on'the sup;
mentof the inner end of the bolt 48 in a slot 64 in the support 34. The parts arethus held normally by the springs 62 with the wipers intheir open position. v c
The connections between the links 58 and the ears 60 comprise pins 66 which are carried by the links 58 and may be. positioned in different holes 68 in theears 60 to. vary the normal spread or limit of movement of the wi-pers'32 forshoesof different widths. In order to hold the pins'66 against accidental displacement whlle permitting them to be readily withdrawn when desired, the:
links 58' carry smallsprings 70the ends of which are positioned in recesses 72 inthe links and are arranged to lie in annular grooves cut in the ends of the pins.
It will be understood that whenthe arm I is swung toward the shoe, carrying the wipers bodily in a direction lengthwise-of the shoe, the pad 52 comes into engagement with the end of the. shoe and stops the movement of the bar 50 and the slide l-G while the movement of the arm 28 and the wipersupport 34L continues. Such clonlit tinued movement of the wiper supportcauses the levers 54: to fulcrum about their points of engagement with the slide 46 and thus to swing the wipers. 82 laterally over the marginotthe shoe during the con-' tinued bodily movement of the wipers' lengthwise of the shoe. member 50 through which the bolt 48 extends permits this member to be adjusted relatively to the slide 46 to vary the time-in the movement of the arm 28 when the'lateral closing movement of the Wipers is to begin.

The wipers thus beginto close inwardly toward the sides of theshoe prior to. any overlaying movement at the toeend. As the arm 28 continues its movenient,afterthe pad 50 engages the shoe, it operates a tripping device 76 on the toe gripper 12and causes the gripper jaws to release the margin of- Eor drivingtacks to hold the margin of the upper in lasted position, the arm 28.
. carries tacking mechanismthe construction of which includesmany features embodied in mechanism shown anddescribed in United States Letters Patent No. 1,280 6l3 granted onv Oct. 1, 1918, upon an application of' Qrrell Ashton. T he machine herein. shown is constructed. to drive threeftacks near the nner edge of the marginof- -the upper, the tacks being fed. througlrtubes 78. to tack holders which are threein number andare mounted on tacker plates v82 carried by the arm 28. The central tacker plate 82 S fixed 0 thfi rln 28, and the two outside plates 82 are mountedfloosely on studs 84 onithe arm, The openings inthe two'outside plates 82 through which the studs 84L extend are sufliciently large 5 to permit lateral swinging movements of the. plates. Each of the outside plates'rests at its upper end upon a, nut 86 at the base of the stud84 and rests at its lower rear corner upon the hea d of a bolt 88. i A rod 90 extends through the two outside plates and.
also loosely through the center plate 82 and, carries a spring 92' wh chtendsto press the two outside plates inwardly toward the center plate and to hold them in engagement with the shoulders 86 and; the bolts 88.
Mounted on the two outside. plates 82 are.
lugs" 94 which carry studs '96. loosely engaged in openings in the Wipers 32. Asthe wipers swinglnw ardly and outwardly they thus causethe two outside tacker plates '82 to. rock about their points of engagement with the nuts. 86. and the bolts 88, and the tack holder s or fingers 80 which are carried by these plates arethus moved with the wipers and/are maintained in position for; driving the. tacks lIl-PI8dQtQTIIlLI1Bd relation tol'the 'edge s 'of thewipersinany position of the, wipers.v Itwill beevide'nt'that he. ax s a u w ch. a iof h P t s 2' -sw1ngs,represented' by a line connecting the nut 86 and the bolt 88, is inclined such relation. to the plane of the shoe bottom, that each. side. tack holder 80iapproaches saidplane as it swings-inwardly; I

In the. operation of the-machine a, shoe; which has been previously prepared in, the V manner herein before desci'lhfit with n- 3S? inserted and its sides back of theftoe 111 permanently lasted condition is presented 111 195 the position indicated by dotted, lines in I 1 with theportion of the shoe which extends over the bottom ofthel last inengagement with. the bottom rest 2] and with portion of the unsecured. margin of the upper'at the 1.0;) toe end of the last of comparatively narrow extent- .widthwiseoit theshoe extending within. the open toe gripper-jaws 22. Preferably a so the upper of the shoe at the toe end 1s dampened, before. the shoe is presented tojthe 10p machine. While holding the shoe in'the pov is necessary, the operator is now afforded an opportunity to make such change as may be 115 required, by manipulation of the ,gripper lever l lin'th'e usual manner. 1 H

engagement with the upper at the endot .13 i
toe, as shown in Fig. 0, and presses the upper against the last in such manner as to hold it substantially against relaxing when the toe grippersubsequently releases the margin. The wipers 32 now begin to close, and by thetime they arrive at the edge of the shoe their wiping edges conform substantially to the lateral contour of the shoe, as shown in Fig. 6. .At about this time and before the wipers become effective to wipe,
the upper inward, the toe gripper is released by the tripping of the. latch 76, the intermediate portion of the margin of the dampened upper having been drawn backward relatively to the portions at the corners ot' the last, as shown also in Fig. 6. During the continued inward movement of the arm.
rendering the wipers effective with less pres sure on the stock at the sides than at the end of the toe, the unsecured margin at the sides of the toe is wiped inward directly from the side edges of the last without disarranging the previously side-lasted portiop, and at the same time the inner edge of the intermediate portion of the margin previously drawn backward by the gripper is gathered substantially between the. tree edges of the portion wiped inward from the sides. In the shoe herein shown the marginal edges c of the upper are stitched by scams 7) along the sides of the shoe to an insertion a which may be of inferior material an d which terminates backof the toe part of the shoe. In operating upon'this shoe the wipers, in their final position illustrated in Fig. 7, shape the stock .in such manner as to leave the inner-side edges (Z of the gathered materialupstanding substantially in front of the ends of the seams Z) and extending forwardly from these seams, while forming one or more backwardly extending folds c substantiz-tlly between the portions (Z. When the wipers have been closed inward at the sides sub stantially as far as the scams 6, as shown in Fig. 7, tacks are driven by the operation of the driver bar 100 to hold thestock in lasted position. It will be evident that since the two outside tack holders-8O are maintained in close relation to the edges of the wipers duringthe inward movement ot the wipers, the tolds in the margin of the stock will be formed in advance of the side tackers and these t ackers will be positioned finally upstanding side edges or folds a? in locations substantially in line with the ends of the seams Z2, as indicated in Fig. 8, and another tack is driven in front'of the intermediate gathered portion; After the tacks have been driven the arm 28 is moved backward to carry the tackers and the wipers away from the shoe the arms 10 are swung outwardly to release the shoe, and the different parts of the machine are returned to their starting positions. i
It will be evident that by the operation of the machine herein described the upper is stretched and shaped to the last at the toe uniformly at allportions of thetoe and the margin of the upper is molded down fiat upon the bottom of the last to produce a smooth surface for the reception of the sole without any pronounced folds which might be accidentally cut at the time when the upstanding gathered edge is trimmed oil, and it will also be evident that the operation produces a lasted toe portion which merges smoothly with the previously sidelas'ted portion back of thetoe. The uniformity of the work also results in therequirement of fewer tacks for holding the margin in lasted position than have been required heretofore; andthis not only saves tacks but also avoids the rapid wear oi the last which is the well known result of .driving repeatedly a large number of tacks in this location;
While the invention is described herein with particular reference to the manufacture of a felt shoe, it will be understood that the novel features are not limited in utility to the manufactureot this particular type of shoe nor in the broader aspects of the invention, restrictedto use upon shoes which have been previously side-lasted.
