. A z 0 emma This invention relates to'improvements in ma- 'chines for lasting shoe uppers and laying soles,
and its main objects are to provide an improved mechanism which simultaneously lasts the side, heel and toe portions of the upper, and which after lasting the upper `supports the work in position during the laying of the sole and provides meansfor pressing and shaping the cemented outer-sole upon the inner sole and welt on .the last, whereby these parts.oi'- the'shoe are permanently assembled in the same machine by. the
same operator, and the usual separate sole-snapt ing and welt-beating machines are eliminated. Other objects of the invention will be apparent from the disclosure. A
yThe invention consists in.the matters herein-l after described: and claimed, and a practlcalf embodiment off means'ior carrying out its various -I features is shown in the .accompanying drawings, -in'which Fig. 1 is atop plan view of a clasting machine constructed in accordance with my invention with itsparts in their .relative positions when the`wipers are spread; Fig. 2 is a similar view with theparts positioned when the wipers are closed to lasting position; Fig. 3 is a transverse vertical view` taken centrally of the machine and partly irrsection on theline I.,3 in Fig. 2

line 1-1 in Fig. 6 showingthe condition lof 'the shoe when it is removed from the machine; and Fig. 16 is a detail view takenon theline ll-IG 'in rig. s.
In the drawings the reference numeral I in dicates a shoe-last, 2 an inner-sole with its corkllining, 3 a shoe-upper and 4 a welt stitched to the upperall these lparts being of usual construction. I 1 V'Ihe metallic supportingy frame of machinecomprises an opposite pair of vspaced parallel angle bars 5 having upper'and lowerJ webs 6 and 1 and an intermediate rectangular baseplate 8 bolted at 9 to vand projecting some-A what inthe rear ofthe lower webs of the bars.
Y Theplate is formed ,with a frontl bearing block il and with a rear pair of spaced bearings l I which support the through rods I 2 'on which the wiper mechanism is carried. The wipers are thin metallic plates formed to stretch or wipe theside,
. '25 .last at one operation. The toe wiper -is comheel andtoe portions 'o f a shoe-upper on the posedof sectional plates l2 and il curved on .their inner edges to correspond-with the toe of the selected last; the outer plate I2 is formed Vwith a cross-tongue i5 which projects 'into' an open-top cross-groove i6 -in the inner or ball plate i4, and each plate is formed with an open.
top -groove i1 extending rearwardly, the groove in theouterplate being directed toward its rear end sligh'tly outwardly away 'from the` center line ofthe machine andthe groove in the balldirected toward its rear end .slightly inwardly... The ,wipers shown are ior the left lasts ofpair, 'except those at therighthand side of Fig. 11 which are for-'thecorrespondingright vlasts of the lpair. l
The heel wiper is com rbi-m' with meneer of the last; one or the p1 is formed with a cross-tongue 2l which projects into an open-top cross-groove 2| in the companion plate, and each plate is. formedwith an open-top groove 22 extending forwardly and directed slightly inwardly toward the center offthe machine. The sidewipers 23' and 24 are clon-- gated plates curved on their inner edges to .con. form respectively with the contour of the inner land outer sides of the shank and ball of the last and formed at their ends to slide in the grooves the lasting 15 t of sectional plateal il and i9 curved on their innerl edges tocon-V I1 and 22, respectively, in the toe and heel wipers. f
Each side wiper is formed-with front and rear closed cam-slots and 25 which correspond with the direction of the grooves in the associated sections of the heel and toe wipers, and headed bolts 21 carried by the latter hold the side wipers in place and control their movements toward and`\ away from the last. The tongue and groove connections between the wiping parts arev so proportioned and formed as to provide flush slip-joints between all working surfaces Vof these parts and thus aord smooth'and continuous wiping sur-` faces onl the welt and upper all around the last and ensure thework being free of any irregularities or ridges. The wipers are tapered or beveled on their lower faces toward their working edges, as shown in Fig. 5 to wipe on the curvature of the upper on the last and avoid making any opening or gap between the welt and upper along the line of their stitching.
The wipers are' supported on carriages con-u structed to spread them outwardly to enlarge l their intermediate opening both longitudinally and laterally to receive the last and upper, and then to close them inwardly in place against the welt, and then to stretch and wipe the upper onto the last. Each section of the heel and toe wipers is supported by a movable carriage con- 'sistingof a vertical pillar 28 and an upright standard 29 bolted at its lower en d'to its associated pillar and flared awayfrom the latter toward its upper end, which terminates in a horizontal bearing flange Ill. The four carriages are disposed in the machine with their pillars grouped about the center thereof and with their standards extending in pairs forwardlyI and rearwardly. A lateral bracket 3l is bolted as at Ila, to the flange of each standard, and each bracket and its associated pillar carriesa vertical adjustable post 32, each section of theheel and toe wipers being supported upon a pair of these posts. 'I'he end posts of the pairs are threaded through the brackets 3| and locked in adjusted position by set-nuts 33, and the side posts are threaded into the pillars and locked in adjusted position by set-nuts 3 4, as shown in Figs. 3 and 4. `Each section of the heel and toe wipers isconnected to its pair of posts by balljoints to permit it to be tilted longitudinally toward its outer endv to an appropriate angle to conform to the top surface of the last and properly engage the welt. For this purpose each post isl formed witha ball-top. having an interior threaded seat 36e to .receive the shank of a screw 31 whose head is formed on its under side with a concave ball-shoulder 38, and the wiper-sections are formed with .upper and lower senilspherical ' seats 39 and 40, respectively, around their screw-holes to t the ball-shoulders and ball-tops, the shanks of the screws being reduced to clear the holes in the wipers, `as shown in Fig. 4a. When the parts are assembled the posts of any wiper section may be adjusted and the .section .tilted to adjust it to the Iangle of the last, and when it is properly positioned its screws are set downtight upon it and lock it on its posts, thus enabling the heel and toe wipers for any style of last to be positioned to conform to the longitudinal contour of the heel and toe portions'of different sizes of lasts of that style, as -shown by the toe section in Fig. 3 for example.
By this construction the sections ofv th e -toewipers may be tipped downwardly towardtheir outer ends to correspond tov the longitudinal curvature of the foot portion of the-sole' of the last from the ball -to the end of the te, and the sections of the heel-wipers may be tippeddownwardlytoward their outer ends to correspond with different inclinations of the heel-seats. The set of wipers for any style of last may include only the sectional heel and toe-wipers. but preferably will include the appropriate side-wipers; as the side-wipers are carried by the ,sectional wipers they are correspondingly adjusted by the vertical adjustments of the latter and move inwardly and outwardly with them toward and away from lasting position, and as the tilt of the heel and toe-wipers is at the ends oi' the sidewipers when these parts are operating on the work it is outside or beyond the working points of the lside-wipers and the continuity of the wiping surfaces is not affected,l as clearly appears vin Fig. 2. The side-wipers are adjusted vertif cally with the sectional wipers, and when the latter are positioned all the wipers remain in proper relation to operate upon the work. -The 4carriages for the wipers are movable in right lines longitudinally and transversely of the' base-plate 8. The front pillars 2l are slidablymounted on a front cross-carrier 4I, and the rear pillars Aare slidably mounted on a rear-cross carrier 42; the carriers are parallel and formed with longitudinal keyways 4I in their sides in which the inwardly projecting tongues 44 on the standards 28 and on the keeper-plates 45 bolted tothe pillars are freely movable to permit the sections of the wipers to move toward and away from each other transversely of the bed-plate. The carriers 4| and 42 are slidably mounted on the longitudinal through-rods I2 to move toward andaway from each other parallel with the center of the machine under the action of a right and lefthand screw-shaft 48 revolubly mounted inthe bearing-block 'I8 and threaded through Ithe lower portions of the carriers. This shaft is operated by a suitable hand-wheel 41 i'ixed on its front end.
To provide a backing for the side-wipers and aiford means for centering them to conform to the ball of the last, opposite transversely movable bearer-bars 48 are carried in slide-boxes 48 mounted on the upper ends of posts 58 supported on the upright branches 5|.Iof a yoke l2, which v in turn is bolted as at 53 to an upright bracket 54 fixed to the inner end ofa slide-strip 55 vwhich is' movable in a central slidewa'y 56 extending lengthwise of the base-plate 8 and retained therein bysidekeeper plates 51 secured to the baseplate by screws 58. The bars 48 are located at about the median line of thema'chine between the front and rear wiper-carriers, witlbtheir outer ends underlying-the side-wipers and connected of diierent styles the bearer-bars 48 are shiftableA by moving the slide 55 t"appropriate position to enable the pins 58 engaging wipers to centralize them to conform to the ball of the particular last employed. When this position is reached the slide is locked'by any suitable lock at its rear end controlled by the operator. In the form of lock mechanism shown in Figs; 3, 8 and 10, a short rock-shaft 5| having an'ecce'ntric portion 82 is journaled parallel with the\tai1 of the slide 55 in .theends 63o! a' bearing-box 84 which bridges the slidway55 and has lateral wings 85 lriding on the base-plate 8 under the keepers 51. The tail of the slide is provided near its rear end with 'opposite recesses 58 in its edges, and the box 54 that the box moves with the slide. 'I'he shaft 6| carries a handle 68 at its rear end, and the parts are so arranged that when the handle is turned down to the position shown in Fig'. 10 the eccentric 62 clamps the tail of the slide between the oor of the slideway and the bearing-box to lock the yoke 52 and its bearer-bars 48 in their desired central position between the wiper-carriers. The handle 68 carries an adjustable stopscrew 69 which abuts against a keeper-plate 51 to prevent the overthrow ofthe eccentric; when the handle is reversely moved the tail of the slide is released, and the handle can be used to move the slide to its desired position. The bars 48 are v ertically adjustable to underlie the side-wipersfin line with different elevations of the heel and toe wipers for diilerent lasts; for example, by headed bolts 10 passing through elongated slots 1| in the posts and seating in the branches of the yoke as in Fig. 5. The arms 5| of the yoke are provided with elongated keeper-strips 12 which engage the sides of the posts.50 and hold them in position to prevent them from turning on their bolts 10 when pressure is applied to the side- 'I'he wiper-carriages are movable on their cross-carriers 4| and 42 to spread the wipers as shown in Fig. 1 to enable the lastwith its prewelt upper in place on it to be easily assembled -on the last-jack and positioned in the plane of the wipers. For this purpose the upper web 6 of each angle-bar carries a transversely movable slide-table 13 having lower runners 19a slideable in transverse key-ways 14 in the web. Each table has a vertical bearing strip 15 at its outer side through which four headed adjusting-screws 16 are threaded.l 'Ihe screws move blocks 11 which run in short slideways 18 in the table and are held therein by top cross-keepers 19 xed to the table; the connection between the screws and blocks to permit the former to turn in the latter while moving them on the table may be made by forming the inner ends of the screws with annular reduced necks 80 which receive the ends of set-screws 8| on the blocks. Each central block is pivoted as at 82 to the inner end of a vertically disposed rectangular plate 83 which extends at an angle lengthwise of the table fr om about its central portion to one end thereof, and each outer block is connected to the outer end of its associated plate by a compound joint formed by a link 84 pivoted at its ends to these lar is connected to this plate by a saddle-piece 88 parts, this arrangement permitting the more extended movement of the outer ends of the plates required in the operation of the machine. Each pillar 28 carries a laterally extending frame 85 bolted to it as at 86 and having 'a horizontally disposed anti-friction roller 81 at its outer end arranged to abut against and run lengthwisel on the inner face ofjts associated plate 83, and each pilxed to the frame and having an outer hooked end 89 slidably engaging the outerface of the plate, -so that as the screws 16 are rotated in one direction they push theplates and wiper-carriages inwardly and when oppositely turned they pullthese partsv outwardly.
.Each table 19 is operated by a toggle-lever 90 whichvis pivoted at its outer end to the underside of the web 6 and at its inner end to a depending ear 9| on the inner side of the table. By pulling the levers down the tables are moved outwardly to spread the wipers to their extreme open position, and by pushing the levers up4 the tables are 1 'moved inwardly to retract the wipers toward the center of the machine to underlie the welt as in Fig. 7. 'I'he toggle-levers arel operated by depending push and pull links 92 whose lower ends are suitably connected to a common vertically movable handle-bar or foot-treadle arranged below the work-table on which the machine rests and constructed to hold the toggle-levers in either of their positions.
The last-jack 93 is pivoted at its lower end to the inner end of an arm 94 which is carried at its rear end on a short cross-shaft 95 mounted in a pair of uprights 96 on a bearing block 91 which rides on the keeper-strips 51 and is bolted as at 98 'to the carrier 42 to move with the latter, so thatwhen the carrier positions the wipers the jack is automatically positioned in association 'bring its pinto position to engage the usual jack-4 holesvin lasts of diierent dimensions and when the last is mounted on the jack the latter is swung to its normal operative position where it is held by the leaf-spring. The arm 94 is curved upwardly to/conform and rest upon an eccentric |0| carried by a 'short cross-shaft |02 which is journaled in the uprights 96 and extends at one end beyond an upright where it is provided with a ratchet-surface |03 and with an upwardly extending hand-lever |04. A pawl |05 is pivotally mounted on the outer end of theupright in position -to engage the ratchet and is normally held in position thereon by a cam-heel |06 on the inner end of a short lever |01 which is pivoted as at |08 at its lower end to the upright and is heldin position to engage and maintain the pawl in its normal position against the ratchet by a coil-spring |09 attached at its end to pins I0 and I fixed respectively on the upright and a lower arm ||2 of the lever 01. A release pin ||3 is set in the lever |01 in position to wipe against the end of the pawl |05 and cam the latter away from the ratchet when the lever is moved inwardly, .so that the shaft |02 is released and the hand-lever |04 can be rocked forward to permit the arm 94 and the last-jack 93 to be moved to their lowered position Ashown in Fig. 3 which they occupy when the last is to be positioned on or removed from the jack. When the last with the shoe-upper in place-on it is put onpvthe jack and the hand-lever |04 is rocked rearwardly the eccentric |0| raises the last and shoe-upper to working position inthe plane of the wipers where they are automatically locked and maintained -by the engagement of the pawl |05 with the ratchet |03 until the lasting operation is completed; then the 'release lever |01 is again moved inwardly to release the pawl and permit the lever head |22 having a. contour to t the toe of the last, the heads being connected to the arms by ball-joints |23 whereby the screws can be rotated to apply pressure while the heads are seated on their work. The head |2| is used to shape the outer-sole III to the last with a mold-block |21 composed of a at piece of wood conforming to the general shape of the lasts and a lining |25 of hard rubber shaped on its lower surface to form the tread of the kouter-sole of the finished shoe. The head, |2| itself may be formed to t the sole to the last and form the mold.
In setting the lasting machine a set of wiper plates corresponding in form with the style of the lasts to be used are positioned loosely on the posts 32, which are adjusted to s et the heel and toe wipers in proper positions and angles to conform to their associated portions of the last, and the screws 31 are set down to lock the wipers in place on their posts. The yoke 52 is set and locked in position so that its bars I8 will position' the sidewipers to centralize the latter to conform to the ball o'f the lasts to be used. The wipers the machine need not be stopped for changes in their sizes or widths.
By operating the shaft 46v the wipers may be adjusted to it lasts ,off diferent sizes of the de- `siredstyle, and by operating the'screws 16 the wipers may be adjusted outwardly for greater widths and inwardly for lesser widths of lasts of diierent sizes or lengths in that style. As the wiper carriages move bodily toward and away from each other in both their Alongitudinal and lateral movements, the'assembled wipers open and close in straight alinement and so conform in their positions during the lasting operations with the contour of the selected style of the last in its various sizes and widths, and the lasting unit presents to the work a continuous working edge without any gaps between its members. Also, by operating the screws 16 the angle or pitch of the plates 83 `to the carriages. may be varied to set the wipers for different gradings of shoes.
In using the machine the tables 13 are spread and the wipers are expanded by turning the handwheel 41 contraclockwise, and a last of the chosen size and width with the'shoe-upper and yits welt in its initial position thereon is vmounted on the last-jack, the lever |04 is operated to raise the last up and bring the edge of the shoe-upper and Welt into the plane of the Wipers, where these parts are locked by the ratchet. The work comes to the machine with the welt temporarily tacked tol the last at its toe and sides, and the insole with its cork-filler temporarily tacked to the last at `its heel and toe. The .tables I3 are now moved inwardly to position the wipers underY the welt as indicated in Fig. '7, and the tacks for` the welt are pulled; if, as sometimes happens,
the toe portion of the last projects above its proper working position in the upper the presshead |22 is swung into position above the toe of the last as approximately shown bythe dotted line position at the left in Fig..11 and operated to press the last to place in the upper. Then the hand-wheel -I'l is rotated clockwise to move the wipers inwardly to their closed position shown in Fig. 2 to pull the upper taut upon the body of the-last and wipe the edge of the shoe-upper and the inner portion of the welt onto the insole on the last, these parts being wiped up snug against the cork-ller as indicated in Fig. 15. The
head |22, if it has been used, isv now released and swung back to its full line position in Fig. 11, the insole tacks are pulled, the insole and welt are wiped withcement, the outersole IM with its heel piece wiped with cement is applied to the work, the mold-block |24 is placed on the outersole, and the press-head I 2| is swung into position above the block, as indicated by the dotted lines at the left of Fig. 11, and its screw is operated to press the outer-sole upon the inner-sole and welt and hold these parts together during the brief interval required for the cement to dry. After the cement sets the head |2I and block are released, and the wipers are withdrawn from the work by turning the hand-wheel l1 contraclockwise, and the tables 'I3 are spread to their 'outer positions; the last with the shoe parts is removed, and another last with its upper and -welt is mounted on the jack, and the operations are repeated.
The two-point support of each section of the heel and toe wipers afforded by its pair of rigid posts 32, and the three-point support of each side-wiper afforded by its seating at its ends on the associated wipers and at its center on its supporting-bar 4I enable the wipers to provide a rigid bed for-the work while under the stress and pressure of the press, and prevent displacementor distortion of the wipers thereby. When the mold presses the adhesive outer-sole into `union with the upper it also shapes or molds Vbeating machine; my invention eliminates the use of these machines with their additional operators.
In practice, a pair of these machines is mounted on the work-table with the press located between them, one of the machines being provided with wipers for a right-foot last and the other-.with wipers for. a left-foot last, as'shown in Fig. 11. By this organization one operator can `attend to two lasting machines. The lasting operation can be carried out upon (say) the left-foot machine of Fig. 11 and the head |2I of the press applied tothe outer sole of the work upon it. While the vsole is under pressure and setting on the first machine, the operator can similarly last another upper in the second (right-foot) machine of Fig. 11, the head |22 now being used if necessary in the right-hand dotted line position in Fig. 11 in the same way as before, and when the work isv iinished, he may apply the pressure-head |2| to the outer sole in the second machine, and while this sole is under pressure and setting he may remove the last and work from the first machine and perform another lasting operation upon it.
It is obvious that my present invention may be used for lasting not only pre-welt uppers, but also for well known McKay, turn, and regular methods of lasting.
