34 Claims.
This invention relates to lastingmachines, and
is herein illustrated as embodied in a machine of the bed type having means movable by the operator to last the sides'of a shoe from its toevention is not dependent upon the character of the means whereby the margin of the upper is secured in lasted position. v
For the purposes in View, the invention, in one aspect, provides a novel construction and arrangement of lasting devices for laying the margin of the upper inwardly over the bottom of the last at the opposite sides of the iorepart, shank and waist portions of the shoe respectively, the term waist portion being used herein to refer to that portion of the shoe where the side edges of the shoe bottom curve inward lengthwise of the shoe heelwardly of the ball line. In View of such inward curvature of the edges of the shoe bottom, the waist-lasting devices, as herein illus- 'trated, are movable laterally of the shoe in different directions than the forepart and shanklasting devices with predetermined components of movement lengthwise of the shoe toward its toe end, In accordance with a further characteristic of the construction shown the several lasting devices are all movable about axes extending heightwise of the shoe in operating on the shoe, the forepart-lasting devices being mov able each about an axis located. opposite the toeend face of the shoe, the shank-lasting devices each about an axis substantially opposite its heelend face, and the waist-lasting devices about axes substantially opposite the sides of the toe at i bers arranged in a series lengthwise of the edge PATENT orrica of the shoe bottom andrelatively adjustable in accordance with the lengthwise contour of the shoe. bottom, the members also being yieldable relatively to one anotherheightwise of the shoe,
in operatingon the shoe. While the machine herein shown is thus provided with devices. for
lasting the ior'epart, shank and waist portions of the shoe, it will be recognized that it is Within the scope of the invention to provide devices for lasting one or ,more of these different portions.
In another aspect, the invention relates more particularly to the construction of the lasting devices. In the machine herein shown each of the above-mentioned overlaying members comprises a leaf spring which acts as a wiper on the margin and outwardly extending portions spaced from one another heightwiseof the shoe to increase .the yieldability of the wiper. Approximately the same amount of pressure will accordingly be applied to the margin of the upper on the'shoe bottom by different wipers, even though they may not have been relatively adjusted preliminarily in accurate conformity to the contour of the shoe bottom. To permit relative adjustment of wipers which are substantially contiguous to one another by turning them about axes extending lengthwise thereof transversely of the edge of the shoe bottom, the construction shown is furthat such thateach wiper formed as above described decreases progressively in width heightwise of the shoe in a direction away from the shoe bottom. i
Sincelastsof different styles or sizes may vary in height, the invention'further provides novel means for determining the position of each'last and shoe heightwise relatively to. the lasting' means by contact with the bottom of the shoe. For this purpose, in the machine herein shown, a height gage ismovable downwardly by a treadle from an initial retracted position to gaging position, and by the sametreadle also a work support is moved upwardly to'carry the shoe into.
contact with the gage. To permit the movement of the work support to be completed by the trea dle after the gage has-arrived at the limit of its movement, as is desirable in View of differences in the heights of different lasts, the treadle in the construction shown is mounted on a yieldable fulcrum. Thfe'machine is further provided with means" forlocking. the work support against retractivemovement from the position determined by the gage, while'permitting the gage to be re-' tractedfrom the shoe upon release of the treadle.
15. of the upper, the spring being reversely curved a plurality of times to provide a series of inwardly The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

The last and its shoe materials are mounted for the lasting operation on a work support including a pin 2 which enters the spindle hole in the heel end of the .last and a toe rest 4 which engages the top of the forepart of the shoe upper. The pin 2 is fast on a block 6 pivotally mounted on a pin 8 carried by a slide l6 which is movable in directions lengthwise of the shoe along guideways 12 formed in opposite sides of a carrier 14. A spring l6 mounted on the slide tends to swing the block 6 about the pin 8 in the direction to press the forepart of the shoe down on the toe rest 4 to assist in holding the shoe in position for the lasting operation. Extending downwardly from the toe rest 4 is a threaded stem I8 engaged by a nut 20 which is mounted between lugs formed on another slide 22 movable along the guideways l2 on the carrier l4. Accordingly the toe rest may be adjusted by the nut 20 in directions heightwise of the shoe relatively to the block 6, as may be required to position shoes of diiferent styles in proper relation to the lasting devices hereinafter described. Extending through pins 24 and 26 which are mounted to turn respectively in the two slides in and 22 is a spindle 2B provided-with right and left threads in engagement respectively with corresponding threads in the two pins, so that by turning the spindle the two slides I0 and 22 may be adjusted toward or from each other. A hand wheel 30 fast on the spindle is provided for turning it. Rotatably mounted on a stud 32 on the carrier I4 is a lever 34 (Fig. 2) the opposite ends of which are connected respectively by links 36 and 38 to the slides H] and 22, so that when these slides are adjusted toward or from each other by the spindle 23 they are maintained at all times at equal distances from the stud. 32. This serves to insure that when the slides are adjusted for shoes of different sizes the ball line of each shoe will occupy substantially the same position forwardlyand rearwardly of the machine, as is desirable in order to position the shoes in proper relation to the lasting devices.
Since lasts of diiferent styles and sizes vary in height, the machine is provided with special means for positioning each shoe with its bottom at substantially the same height for the operation of the lasting devices thereon. For this purpose, in the use of the machine on each shoe, a height gage 40 which is arranged for contact with the bottom of the shoe at its ball portion is moved downwardly to a fixed predetermined position and the shoe is forced upwardly until it contacts with the gage, the movement of the gage and the movement of the shoe in the machine herein shown being effected by depression of a single treadle 42. The gage 40 is supported over the shoe on one end of an arm 44 which is fast at its other end on a pin 46 rotatably mounted in a bracket 48 on the frame of the machine, and also fast on this pin is an arm 50 pivotally connected to a link 52. This link is pivotally connected to another link 54 mounted to swing about a pin 56 on the frame, and integral with the link is an arm 58 connected by a link 60 to the rear end of a laterally offset arm of the treadle 42, this treadle being mounted to swing about a fulcrum rod 62 supported as hereinafter described. It will thus be seen that when the treadle is depressed against the resistance of a spring 64 it acts to swing the two links 52 and 54 from the positions in which they are shown in Fig. 1 to positions in alinement with each other, as illustrated in Fig. 3, such movement of the links being limited by engagement of the link 54 with a pin 66 on the frame. In this manner the gage 4B is swung from its initial retracted position, where it does not interfere with the mounting of the work on the work support, into position to determine the proper height of the shoe by engagement with the bottom of the ball portion of the shoe. It will be evident that by reason of the character of the means hereinbefore described for adjusting the slides l0 and 22 for shoes of different sizes, corresponding portions of such different shoes will be presented under the gage. The gage 40 is carried by a stem 68 threaded in the arm 44, so that by turning the stem the gage may be adjusted relatively to the arm in directions'heightwise of the shoe to vary the height at which the shoe is presented, the stem being held in adjusted position by a lock nut 10.
To carry the shoe heightwise into contact with the gage 40 the shoe support is vertically movable, the carrier l4 being provided with downwardly extending rods 12 and 74 slidingly mounted in guides 16 on the frame. The carrier is connected by a link 78 to one arm of a lever 80 pivotally mounted on a pin 82 on the frame, and the other arm of this lever is arranged to be engaged and operated by a pin 84 carried by the treadle 42, the arm having a recess 88 therein to receive the pin. When the parts are in their initial positions the carrier M is in a lower position than illustrated in Fig. 1 with bosses 88 thereon in engagement with the upper ends of the guides '18 and with the front arm of the lever 80 raised so that the pin 84 is in the recess 88. When the operator depresses the treadle 42 the gage 40 is moved downwardly to its operative position, determined by engagement of the pin 66 with the link 54, before the shoe has been moved upwardly far enough to contact with the gage. In order to permit such further movement of the treadle 42 as toraise the shoe into contact with the gage, the fulcrum rod 62 which supports the treadle is mounted on a link 90 which may swing downwardly about a pin 92 on the frame against the resistance of a spring I contact with the gage. For holding the shoe support at the limit of its upward movement determined by the gage 40 a pawl 98 is pivotally mounted on a pin I00 on the front end I of the lever 80 and cooperates with ratchet teeth formed on a plate Iii2*'=fast on the frame to prevent return movement of the lever 80 when the operator releases the treadle. A torsion spring I04 carried by the lever 86 holds the pawl in engagement with the teeth. After positioning the shoe at theproper height by depression a of the treadle the operator releases the treadle to permit the gage '40 to be moved upwardly away from the shoe so as to avoid-interference with the lasting devices. Toper-mit the shoe support to be lowered by gravity to its initial position after the lasting operation the'pawl 98 is swung by the operator away fromthe ratchet teeth by depression of a treadle llifi'which operates a crankv arm I 08 connected by a link Mil to the lower end of the pawl.
For lasting the sides of a shoe positioned an supported as above described the machine herein shown is provided with different pairs of lasting devices movable to lay the margin of the upper inwardly over an insole on the last at the opposite sides of the forepart, shank and waist portions of the shoe, respectively, the forepart-lasting devices being designated generally by the reference characters H2 (Fig. 2), the shank-lasting devices by the reference characters I I4, and the waist-lasting devices by the reference characters I I6. Each of the several lasting devices comprises a group of overlaying members or wipers II8 arranged-in a series lengthwiseof the edge of the shoe bottom for wiping the margin-of the upper over the insole. These wipers, except for differences hereinaftcr referredto, are all alike, and each of them consists of aleaf spring reversely curved a'pl-urality of times, as illustrated in Fig. 4, to provide a; series of inwardly and outwardly extending portions I20 spaced from one another heightwise of the shoe to increase the yieldability of the wiper. The upper-engaging portions of the wipers of each groupare in substantially contiguous relation to one anotherybut the wipers decrease progressively in width heightwise of the shoe in a direction away from theshoe bottom to permit them to be relatively adjusted as'herein'after de scribed. The wipers N8 of the forepart-lasting devices H2, herein illustrated as fourin number at each side of the shoe, are fast on the inner end portions of outwardly extending arms I22, and the two groups of arms-are supported by holders I24 which are carried by hand levers I26 both mounted to swing about a vertical rod I28 supported bythe frame in a location opposite the toe-end face of the shoe. Each group of arms I22 is secured adjustably to its holder I24 by clamping blocks I3tl- (Fig. '7) movably mounted in aguideway in the holder and recessed to engage spherical bosses I32kon the sides of the outer end portions of the arms, the blocks being operated to clamp the arms firmly by one or the other. of two. screws I34 and I35'threaded in the holder. It will thus be:seen that the arms I22 are mounted: for universal adjustingi'movements and that by swingingv them heightwise of the .shoe relatively to oneanother and turning them about axes extending transversely of. the
edge of the shoe bottomlengthwise of the wipers H8= mounted; thereon the wipers may be adjusted to conform substantially to the lengthwise contour of the'portions'of the shoe bottom on which they operate, the clamping blocks I30 being shaped to permit the required adjusting movements of the arms. Further toassist in adjustingv the forepart-lasting devices in proper relation to shoes of different styles, each of the holders I24 may be swung relatively to its supporting lever I26 about an-axis' ext'ending laterally of the shoe,the holder being provided for purposes of this adjustment with a; stem I36 rotatable in a split bearing I38 on the lever I26 and held se' curely inadjusted position-by a screw I40 which which contracts thisbearing. The two levers I26 are so formed that whilethe lasting. devices H2 supported thereon are at substantially the same height, the hub of the left-hand lever underlies the hub of the right -hand'lever on the rod. I28,
somewhat in'accordance withthe size of theshoe.
It will be understood that in operating. upon a shoe substantially smaller than illustrated the wiper I iS nearest' the toe end of' the shoe at each i side may, ifv desired, be so positioned by suitable adjustment of its supporting arm I22 as not to engage the shoe. 1
The shank-lasting'devices I I4 which, in the con struction shown, comprise five wipers I I8 at each: side" of" the shoe, are supported and operated by a pair. of hand levers I42 which are pivotally mounted at t-heir front ends on a pair of vertical rods I44 spaced somewhat'from each other widthwise ofithe shoe'but'located substantially opposite'the heel-en'd face of the shoe. Each of the rods I44 extends through a bracket I46 on the frame and is threadedin the frame at its lower end, a hand wheel I48 being provided at its upper end for screwing it into the frame. The hub portions of the levers I42 are heldon the rods I44 between collars I50'fast on therods, so that the levers are held. against upward movements.
' These levers are operated by handles I52 fast thereon in locations. between the pivot rods I44 and the lasting devices H4. The "wipers I I 8 of these devices are fast on arms I54 which are like the arms I22 of'the forepart-lasting devices except that they. are of angular shape, as illustrated in Fig. 2, to provide suitable clearancebetween the shank-lastingdevices and other parts of "the machine. The armsI54 are each individually adjustable in the samemanner as the arms I22 and are clamped in adjusted positions by means of the same" character as illustrated in Fig. '7, this clamping means, however, being mounted directly on each ofthe-levers-I42 instead of on a holder' adjustableirelatively to the lever as in the case ofeach of theforepart-lasting devices.- Itwill be understood-that in operating on ashoe considerably" smaller-' than illustrated the two wipers IIB which are located nearest the heel end of the shoe may be rendered inoperative by suitable adjustment of the corresponding arms The wipers II8 of the waist-lasting devices II6 which, as herein shown, are three in number at each side of the shoe, are arranged to wipe the margin of the upper inwardly between the portions operated upon by the shank-lasting devices and the portions operated upon by the forepart-lasting devices. These waist-lasting devices are supported and operated by hand levers I56 which are mounted for swinging movements about vertical studs I58 fastened to the frame in locations substantially opposite the sides of the toe of the shoe and spaced substantial distances from the shoe widthwise thereof. The hand levers I56 extend to positions where the operator at the front of the machine can conveniently manipulate them, and they are of angular shape, as illustrated in Fig. 2, to position the two groups of wipers in an angular relation to each other corresponding in general to the angular relation of the opposite side edges of the shoe bottom extending heelwardly of the ball line. These two groups of wipers II8 are mounted on arms I66 which are like the arms I22 of the forepart-lasting devices except that they are of angular shape as illustrated in Fig. 2 for purposes of clearance. The arms I66 are adjustable in the same manner as the arms I22, and they are clamped in adjusted positions by means (Fig. 6) of the same character as in the case of the forepart-lasting devices. Each group of arms I66 and its clamping means are supported by a holder I62 provided with a stem I64 rotatable in a split bearing I66 on the lever I56 to assist in adjusting the wipers in proper relation to the shoe, the holder being secured in adjusted position by a screw I68 which contracts the split bearing I66. It will be evident that the studs I58 about which the levers I56 are swung are located in such relation to the shoe that the wipers I I8 of the waist-lasting devices move in paths so curved that they have substantial components of movement lengthwise of the shoe toward its toe end, as is appropriate by reason of the fact that the side edges of the shoe bottom where these wipers operate curve inwardly from the ball line toward the shank portion of the shoe.
It is assumed that in the use of the machine herein shown the shank-lasting devices II4 will be moved inwardly over the shoe bottom before the waist-lasting devices I16, and in order that the margin of the upper may be wiped inwardly in a satisfactory manner at the junction of the shank and waist portions of the shoe, those wipers II8 of the shank-lasting devices which are located nearest the toe end of the shoe are so formed that when they are over the shoe bottom their edges I16 (Fig. 2) which are next to the waist-lasting wipers are substantially tangential to the paths of movement of the latter. By reason of this construction the margin of the upper which lies next to the shanklasting wipers at each side is wiped inward substantially throughout its width, and there is, moreover, no danger of wrinkling or pinching the margin of the upper between the waist-lasting wipers and the shank-lasting wipers. Furthermore, those wipers I I8 of the waist-lasting devices which are nearest the toe end of the shoe are, for a similar purpose, so formed that the portions N2 of their, edges next to the forepart-lasting wipers are substantially tangential to the paths of movement of the latter. At the end of the operative movements of all the lasting devices the wipers I I8 are accordingly in substantially continuous, engagement with the margin of the upper all along the opposite sides of the shoe bottom from the toe portion to the heel portion of the shoe. It is contemplated that preferably the wipers will be moved inwardly to substantially the same positions regardless of the size of the shoe operated upon.
Before a shoe is presented to the machine it will ordinarily have been pulled over and may or may not have been lasted at the toe and heel ends, the shoe herein shown being one the opposite ends of which are to be lasted after it leaves the machine. The operator mounts the last and shoe on the work support, tipping the lastpin 2 against the resistance ofthe spring I6 by the action of the last thereon to permit the forepart of the shoe to be positioned over the toe rest 4, the spring then holding the shoe pressed down on the toe rest by its tendency to tip the pin in the opposite direction. By depression of the treadle 42 the operator then moves the height gage 46 downwardly to the limit determined by engagement of the pin 66 with the link 54 and raises the work support to bring the bottom of the shoe into contact with the gage, such contact being effected by further movement of the treadle after the gage has arrived at the limit of its movement, as permitted by the yieldable fulcrum support on which the treadle is mounted. The operator then releases the treadle to permit it to be returned to its initial position and the gage to be retracted from the shoe by the action of the spring 64, the work support, however, being locked against return movement by the pawl 98. Thereafter the operator swings the levers I42 inwardly to cause the shank-lasting devices IM to wipe the margin of the upper inwardly over the insole at both sides of the shoe simultaneously, or first at one side and then at the other side, as may be desired. Next, while the shank wipers are over the shoe bottom, the operator swings the levers I56 to operate in a similar manner the waist-lasting devices I I6, and while the wipers of these devices are over the shoe bottom he swings the levers I26 to operate the forepart-lasting devices H2.
Concurrently with the use of any of these lasting devices the operator may, if desired, use hand pincers to apply a pull to the margin of the upper. A suitable adhesive will have been previously applied to the shoe for securing the margin of the upper materials to the insole, and accordingly the margin adheres to the insole when it is wiped inwardly in the manner above described, the wipers H8 by reason of their construction being sufiiciently yieldable to insure substantially uniform pressure on the margin of the upper all along the forepart, waist and shank portions, of the shoe'bottom even though their supporting arms may not have been previously adjusted to position the wipers'in exact conformity to the lengthwise contour of the shoe bottom. After having thus lasted the sides of the shoe the operator retracts first the forepartlasting devices, then the waist-lasting devices, and thereafter the shank-lasting devices from over the shoe bottom, depresses the treadle I06 to unlock the work support and permit it to return to its initial position, and then removes the shoe from the machine.
