  • the surface '3M may be relieved, as at 3I'5,:so that the upperis freed from the action of the roll quicker but' -is still confined in the space between the relieved portion 3I5 and the roll I0.
  • This latter arrangement facilitates the action of the wiper since the upper is permitted to drop down toward the shoe 'bottom sooner than is the case withfthe wider operating surface 3M, as

  • their inclined lead# on the upper being wholly ing edges extend at an angle to their line of movement. Accordingly, the upper, as it leaves the roll I 0 and sleeve l2, is smoothed down nicely and with a wiping action which has a component operating in the direction of feed.
  • the edge gage roll is so located that it bears against the upper up close to the insole and just about below the point where the influence of the roll ceases.
  • edge gage roll 90 does not interfere with the tensioning of the upper but instead is applied at the proper point to hold the tensioned upper against loosening before it is engaged by the wiper. Also, withthe edge gage roll contacting the edge of the shoe near the insole, it will hold the shoe properly positioned at all times as the lasting operation proceeds around the shoe.
  • the illustrated shoe is to be lasted all the Way around its edge and when this lasting operation has been nearly completed the operator depresses the roll and sleeve-controlling treadle, just before ⁇ the previously lasted portion of the upper is close to one of the previously lasted portions as possible and would finish when the other previously lasted portion was reached.
  • the action of the wiper extends beyond both the starting and nishing points so that a smooth junction is obtained at each place.
  • the heightwise stress that is exerted by the roll on the lasting margin y of the upper will be transmitted to adjacent portions of the upper on either side of the point at which the roll is at any instant operating. Accordingly, in operating all the way around the shoe. although the roll and vsleeve are separated just before the lasting operation is completed by the wiper, as above explained, all parts ofthe upper will be tensioned and the sameis true where the lasting operation is started and finished adjacent to previouslylasted portions of a shoe.
  • the action of the roll I0 on the upper is wholly frictional so that the feeding movement of the shoe is entirely under the control of the operator. That is to say, he can hold the shoe fixed and let the roll slip over the upper. and he does so at the beginning of the lasting operation. Also, if during the progress ⁇ of the lasting operation it is desired to slow down the lengthwise feeding movement of the shoe, as, for example, to prolong the heightwise pulling action of the roll at any particular point or to facilitate the passing of any irregularity on the shoe bottom by the shoe rest 300, the operator, by overcoming the feeding component of the frictional drag, can cause the roll to slip until the desired length of pull has been obtained or the irregularity on the shoe bottom passed.

  • the mounting plate is secured to a supporting arm 43'4, that corresponds to the wiper-supporting member 234, Figs. 2 and 4, and which is attached to the machine frame I6 by bolts 432, in such a Way as to be angularly adjustable about the axis of the post 424 by means of screws 436 that are threaded into curvedextensions on the arm 434 and which pass through arcuate slots 438 in the plate 430.

45 olaimej. (ol. lief-if) This invention relates to shoe machines, 4and is herein shown embodied in a machine'forla'st-- ing .the upper of a shoe on its last in over the. bottom of the shoe and for pressing 'the lasting margin of the upper smoothly and firmly against the shoe bottom. However, it is to be understood that the machine of the present invention isnot` limited vin use to the lasting of shoes but, instead,
is of broader utility and may be employed for per-j forming similar shoemaking operations on other shoe parts. Y An object of this invention is to provide a novel and improved machine for lasting shoes, orr
novel machine has means for so exerting a fric-A tional drag on the lasting margin ofthe upper of a shoe on its last as simultaneously to tension it in a direction heightwise of the last, to draw'it in over the bottom of the shoe, and to exert a feeding stress thereon, together with` means forl wiping and pressing the overdrawn portion iirrn-l ly and smoothly against the bottom of the, shoe. More particularly, the means herein shown for applying the frictional drag comprises a driven roll and a cooperating pressure memberiflor -en-k gaging the opposite face of the lasting margin of thev upper, said roll and pressure member being so constructed and arranged that the frictional drag exerted by the roll has a component ofy stress tending to tension the upper heightwisej of' the last, a component of stress tending to draw its lasting margin in over the bottom of the shoe and also a component of stress tending-to pass the lasting'margin vbetween the rollandpressure member thus to bring adjacent portionsthereof successively into the zone of operation ofthe roll and to feed the shoe. As the lasting-margin leaves the roll and pressure Vmember it is immediately pressed smoothly and firmly against the bottom of the shoe by wiping `means which preferably, and in accordance With a further feature of the invention, comprises a driven rof tary member that is yieldingly urged toward `the shoe bottom and so constructed and arranged as to have a continuous wiping actiondirected in-` wardly from, and atan angle -to,lthe edge'ofthe shoe, The lasting-margin of the upper, or other shoepart, having been previously coated with'a suitable adhesive, this action of the Wiper Will cause it to\ besecured, smoothly and effectively,
t tothe bottom of the shoe.
Tepreventupward movement of the shoe by the heightwise `tensioning action of the frictional drag of the roll, thev machine further is provided with agshoe rest against which the bottom of the shoe is'helduby the operator, and an edge gage is conveniently arranged adjacent to the pressure member. f ordeterrnining the position of the shoe laterally withurespectto the roll and the pressure member. Ereferablyand as herein shown, thefpressure member-comprises a sleeve having a surface that partially surrounds the roll and which is yieldingly urged toward the roll so that a part of thelasting margin of the upper is held in frictional engagement with the roll and also wrapped around the rell inwardly over the shoe bottom, Y The axisfof the yroll is so inclined to the plane of the shoebottom that the frictional drag applied directly to the lasting margin of the upper hasafeeding component of ystress and a component of stress tending to tension the upper in adirection extending heightwise of the' shoe. Also, because of the'invvard wrapping of the upper around the roll by the' pressure member, the frictionaldrag also has astress component, acting inwardly of the'shoe', 'which tends'to draw thelasting margin of theupper in over the shoe bottom. Preferably, and 'as' herein disclosed, means 'are provided for changing the inclination of the `rollio vary the relative intensities of the` tensioning andfeeding stress components. To facilitate the introduction of the Work, as well as the termination of the lasting operation, means are provided for elevating the'wiping means and for separating the pressure member and roll. Conveniently,- the latter means 4is arranged to Withdraw the edge gage from operative position.
These 4and other objects and features of the invention WiILap'pear in the following detailed` description of the embodiment thereof illustrated in the accompanying drawings and Will be pointed out in tne claims.A In the drawings, Fig. 1 isa View lin side elevation of a machine embodying this invention; Y

Referring now to the drawings, especially Figs.
l, 2, 3 and 4, the operative elements of the illustrated machine comprise'a driven roll 1.0, a cooperating pressure sleeve |2 .and ra .rotary wiper I4. These elements are all ymounted Ion a frame |6 which is supported-on the top of a post I8 that is adjustably secured to a-bracket adapted lto be will be moved in this direction, and forwardly of yIii the machine, against the action of spring 54.
yThe sleeve l2 is carried on the outer end of a slide |00 which is mounted in a guide block |02 and is yleldingly urged toward the roll I0 by means of a compression spring |04, the force of which may be adjusted by` means of a screw |06, Fig. 4. The block ||i2VA is formed integrally with lthe cross-web `l5 and thus moves with it and the plates 14 and 16 when the latter are angularly adjusted on the U-shaped member 30. For moving the sleeve |2 away from lthe roll I0, the slide |00 is provided with a pin ||0 which projects `through slots ||2 in the opposite sides of the block |02 and the ends of this pin bear against the curvedlower ends ||4 of a bifurcated lever ||I that is pivotally mounted on the block mounted, as shown, on a platform 22 or other equivalent supporting structure. The roll I0 has i a `stem 24 by means of `which it is 'secured to a shaft 26 that is journaled in an elongated block 28, Figs. 3 and 4. Thisblock is slidablysupported on ya U-shaped member -30 by means of an elongated cylindrical boss 32 that passes through a l hollow sleeve 34 formed integrally with the mem ber 30. The shaft 26 is driven, to rotate the roll in the direction shown in Figs. l6 'and 7, by means of a pulley and fbelt 4'2 which passes over a second pulley 44 mounted on a countershaft 46 that is supported on the frame I6, Figs, l and '2.
Secured vto the vouter end of the boss 32 by means of lock nuts 48, 48 is an angled bracket '50 and carried by this bracket is an ear 52 between which and a part ofthe frame a tension spring 554 is stretched for normally holding the roll 1"0 its extreme rearmost position, as shown *in Figs. 1, 3, 4 and 6.
The U-shaped member 530 is mounted with :the
capability of angular yadjustment on 'the frame IB by means of la trunnion shaft B0 which passes through a hole in a frame member62 'andis locked in adjusted position by means of aset screw B4,
see Figs. 1 and 3. The .bleek 2s hasn-at sides and slides between spaced parallel guide plates 14,16
which are connected together by 'means of 'a crossweb 15, Figs. 3 and 4, extending between the lower ends of their back edges. Formed integrally with this web is a stud 80 that is'threaded at its outer end and which Vprojects rearwardly through a bore in the back part of the member 30. vThis bore is in alinement with the axis of the-sleeve 34 and when a locking nut 82 is loosened the plates may gular position of the block and the inclination be swung around this axis to acl-'just the an-` of the roll, Vin `a direction lengthwise of the shoe Y and as viewed in Fig. 5. A stud 90, having -a bifurcated end 92, is screwed into a plate T8, secured to the upper end of the `block 28, and connected to this stud, by means of 4a pin 86, 'is one end of an operating link "94 that extends vfor-` wardly of the machine from 'the upper `arm 95 of a double bell-crank lever 98. This end of the link 94 is provided with a slot 88 through which the ,pin 8B extends, so that an appreciable Aamount of lost motion movement of the link 94, to the left as viewed in Figs. 1 and 3, and to the right in Figs. 2 and 4, is 'required before the block 28 1| |12 by means of abolt I i8 Extending rearwardly from the .upper end of this lever I I6 is a link |29 whichY is connected to an ear |22 adjustably mounted on the upper end of ka lever |124., Eig. 2. This lever is pivoted on a stud |26, 'carried by a bracket |28 which 1s bolted to the frame It, rand has, on its lower end, .an arm |30 `carryinga roll |32. This arm Lis secured to the lever by means of a bolt |34 which .extends througha slot |35 in the arm, so that the vertical position of the roll "|32 may be varied, and is .guided at :one v end by :anoutturned'flangecl 3.8 on the' lever |24. iElevation of this roll, from Vthe position shown in Fig. 2, will swing lever |24 in a clockwisedirection bolts |52, |54 and slots |56, |53, While the Supe porting larm |48, to which the cam bar |40 is secured by `screws |60., is adjustably connected. tothe post by means vof -a screw 162 and slot |64 Adjacent yto its 'camming surface, the team .bar |40 is 'also supported on an .anti-.friction roll 16:6 carried at the upper end of a vertically adjustable slide Y| 68 mounted in a guidemember 1.1.0 carried by the vframe I0, a screw |12, having a locknut |13, being provided for adjusting ithe vertical position of `the slide |68. The slide |44 .is connected, by means of link |14, Fig. 2, tothe lower arm |16 of the bell-cranklever 98,.,which is pivoted to the frame on a bolt |15 extending between two angle brackets |11, so as to be moved rearwardly of the machine, from the position shown in Figs. 1 and 2, when the bell-crank lever y'98 is elevated by means of a treadle rod |18, connected to a treadle, not shown. A compression spr-ing |80, Fig. 1, interposed between an abutmentsleeve |82, bearing on the bottom of lthe bench 22,and a collar, not shown, ron'the treadle rod normally holds the 'bell-crank lever 98 in the dow-n posi the roll |32 and cause the lever |24 to be .turned in a clockwise direction, "thus causing, vthrough link 20, a similar movement o `the lever' |1t6 which, in turn, acts on the pin IIO ,and draws the slide and sleeve I2 back, away from the roll I0, to the position shown in Fig. '7. Atflrst, the forward movement of the link 94 is ineffective, due to the lost motion provided in ,its connection to stud 90, and the roll I0 remains fixed. However, when this lost motion is taken up, movement of the link 94 is transmitted to the block 28 and the roll is moved forwardly of the machine, against the action of spring 54, to the position shown in Fig. 7. When the treadle is released, the link 94 is moved rearwardly and the slide |44 and cam bar |40 are moved forwardly by spring |80. Spring 54 now keeps the lost motion in the connection of link 94 to stud 90 taken up so that theA roll I0 moves rearwardly to its operating position, see Fig. 6, determined by engagement of block 28 with web 15, Fig. 4, before the cam bar |40 hasmoved forwardly far enough for roll |32 to ride down over the inclined surface |42. Upon the continued forward movement of the slide |44, permitted by the aforementioned lost motion as the treadle is fully released, spring |04 moves the slide |00 and sleeve I2 forwardly to their operating positions, see Fig.
, 6, the roll I32 now traveling down over the inclined camming surface |42. To prevent actual contact of the sleeve against the roll, the lever I6 is provided with a stop screw I 86 which bears against the top side of the block |02.
With this arrangement for separating and bringing together the roll and sleeve, the sleeve moves radially toward the roll while the latter is stationary, and a better engagement of the curved operating surface of the sleeve with the upper, which it presses against the roll, is obtained. If the sleeve were moved to its operative position rst, the roll, coming in as it does at an angle instead of radially, might be held away from its proper position by engagement with the upper at the near edge of the sleeve, the action of spring 54 then tending to bind the slide |00. With therroll all the way in, due to the Obliquity of the line of its action, spring |04 is not powerful enough to move the roll back.
Mounted on the lfront end the slide |44 is an antifriction edge gage, illustrated as a roll |90, which is carried by a finger |92 projecting from a bracket |94. This bracket is mounted for lateral adjustment on an angle member |96, by means of a screw |90 and slot 200, and the angle member is mounted on the slide for heightwise and lengthwise adjustment on the slide by means of a bolt 202 and cross-slots 204, 206. When the treadle rod |18 is moved down this edge gage is shifted from the operative position of Fig. 6 to the inoperative position of Fig. 7.
The rotary wiper I4 comprises a hub member 2|0 secured. by setscrew 2| I, Fig. 11, to a shaft 2I2, from which extend a circumferential series of inclined teeth 2|3 the lower faces 2I4 of which are elements of a very low cone. Above their lower faces these teeth are covered by a cupshaped guard member 2|6 having a hub 2I8 that fits over the wiper hub 2I0 and is secured thereto by a setscrew 220, Fig. 11. The shaft 2|2 is journaled in an elongated bearing member 230, Figs. 3 and 4, having a laterally extending boss 232, threaded at its outer end, which passes through a bore in the extreme outer end of a curved supporting member 234, extending from the frame I6, Fig. 4. A nut 236, on the threaded end of the boss 232, serves to draw the member 230 tightlyl against the member 234thus to hold it, as Well as the shaft 2I2 and wiper I4, ln any desired angular position. Secured to the upper end ofthe shaft 2I2 is a pulley 240, and between the lower face of this pulley and the upper end of the bearing member 230 is a sleeve 242 loose on the shaft 2| 2. Formed integrally withthis sleeve is a plate 246, and pinned to this plate is one endof a lever 250, fulcrumed'at 252 on a bifurcated stud 254 mounted on the member 234,
by a collar 262 fast on the shaft 2 I2, Figs. l and 5f This spring yieldinglyholds the wiper down in its lowermost position with the lower edge of .the
plate 246 resting on a stop member 264, adjustably secured to the bearing member 230 by screws 266, Fig. 4. This position of the wiper is ap-A preciably lower than that shown in Fig. 5 so that when the machine is operating the wiper is yieldingly forced by the spring 260 against the work and is able to accommodate itself to different operating levels. A treadle, not shown, connected to rod'256, is provided for elevating the wiper when desired.
A belt 210 connects the pulley 240 with a pulley 212 on the countershaft 46, and an adjustable idler pulley 214 is provided for tensioning this belt, Fig. 1. Similarly, an idler pulley 216 is provided for keeping the belt 42, which drives the roll |0, taut. This idler is mounted on one end of an 'arm 218 that is pivoted on the top of the frame I6, and a spring 280 is stretched between the other end of this arm and a thumbscrew 282 for yieldingly holding the pulley against the belt. The eountershaft 46 is driven from a motor 284 by means of a belt 286 passing over pulleys 288, 290 and 292.
For supporting the work against upward movement, the machine is provided with a shoe bottom rest 306 which is secured to a downturned portion of the bracket 50 by means of screws 302, Fig. l. This rest is shaped to extend part way around the -roll I9 and has a lower horizontally extending toe portion 304 that is turned up at its extreme end to facilitate sliding over the bottom of a shoe, see Figs. 3, 4 and 5.
The roll I0 is conical, tapering in slightly from its lower end upwardly, and has a knurled operating surface 3|0 that is separated into four bands by spaced annular grooves 3|2, Figs. 4 and 5. The operating surface 3|4 of th'e sleeve I2 is substantially complemental to the outer surface of the roll which it surrounds for an angular distance of about 45 degrees, see Figs. 6 and 7. Formed integral with the sleeve member andextending from the side at which the upper enters the space between the sleeve and roll, hereinafter referred t0 as the entering side, is a. deecting web 3U:` having a curved surface 3I8 which merges with the operating surface 3I4 of the sleeve, see Figs. 6 and 7. The surface 3| 4 extends outwardly around the roll, toward the front of the machine, so that the side at which the upper leaves the space between the sleeve and roll, lhereinafter referred to as the leaving side, is positioned some distance inwardly of the edge of the shoe bottom from the entering side, see Fig. 6.
The exact shape of the operating surface 3 |4 of the sleeve I2 may be varied to suit different 0perating conditions. For example, as shown in Figs. 9 and 10, which are sectional views at the bottom and top,l respectively, of the roll VI0 and a surfacemay even be cylindrical. With this ztype of sleeve the pressure of the lasting` margin against the roll will decrease upwardly from the bottom of the roll, thus allowing Vsome self adjustment ofthe outer edge of the lasting margin of the upper as it is acted upon by the roll. `vAlso the surface '3M may be relieved, as at 3I'5,:so that the upperis freed from the action of the roll quicker but' -is still confined in the space between the relieved portion 3I5 and the roll I0. This latter arrangement facilitates the action of the wiper since the upper is permitted to drop down toward the shoe 'bottom sooner than is the case withfthe wider operating surface 3M, as
shown in Figs. 5, 6 and '7. n
The operation of thismachine to last a shoe is as follows: With motor "2134 running, both' treadl, which are located side by side, arevdepressed to separate the roll Iii and sleeve I2, to l'elevate p the wiper I4 andto withdraw the edge gage 19D from operative position. The shoe on its last .L is now presented to the machine, bottom up, with i th'e lasting margin M of the upper U inserted `be- 1 tweenthe roll I8 and sleeve I2 and the bottom 1 of the shoe brought up so as to bear against the shoe rest '369, see Fig. 7.V The treadle which oontrols the roll and sleeve and also the edge gage is next released, allowing spring 5d to pull the roll inwardly tothe position shown in Fig. 6 and spring |80 to lower the lbell-crank lever 98 and move cam bar IM forwardly so that spring 164 may move the sleeve I2 in against the lasting margin of the upper and press it yieldingly against the rotating roll Il. The downward movement o the bell-crank lever 98 also moves the edge gage I9@ forwardly into its operative Y position, the exact location being determined by the engagement of an adjustable stop screw 320, mounted on the frame, with an abutment 322 carried by the slide 5M, see Fig. 1.
- The rotating roll Iii now exerts a strong frictional drag on the inside surface of the lasting margin M which is being rmly, `but yieldingly, pressed against it` by the sleeve I2 `under the action of spring IM. As already explained, because of th'e angle between the direction of movement of the roll and the direction in which this pressure is applied, spring 54 holds the roll fixed against outward movement. from an inspection of Fig. 5, due to the inclination, in a lengthwise direction, of the axis of the roll to the bottom of the shoe, which is maintained in a substantially horizontal plane as the shoe is presented to the machine by the operatcr, this frictional drag will exert on the upper a component of stress tending to pull the upper in' a direction heightwise of the last L and also a component of stress at right angles thereto tending to move the upper `in a direction parallel to the bottom of the shoeand hence to feed the shoe in alengthwise direction. Referring to Fig. 6, it will be seen that since the sleeve extends around the roll, from the entering side to the leaving side, for an appreciable distance inwardly from the edge of the shoe bottom, the frictional drag of the roll will also exert a component of stress tending to draw the lasting margin of th upper in over the bottom of the shoe. Y
As will be apparent from an inspection of Figs. 4 and 6, the operative position of the edge gage |90 is such thatv the point of engagement of the lower` end vof the roll I0 with theV upper, as it is pressed against the roll by the sleeve I2, is loagences' v cated .ashort distanceoutwardly from the edge ofthe. .shoe bottom. The axes of the rolly and sleeve are inclinedllaterally `of the shoe,'see Figs.. 3 and 4, so that .as the upper .is tensioned ina direction heightwise of the last lit .is also .drawn outwardly and held away from the edge of the insole Ithu's avoiding any vtendency .to lift .the edge of the insole. from the bottom of the shoe. By giving the roll and sleeve vthis lateral inclination and .adjusting the 4U shaped member 30 about the'axisof the shaft 80, theamount of which'rnay be varied .byfloosening .the setscrew 64, the vupper' is engaged lower down and very close to the plane of A.the insole. The conicity of the roll and sleeve permits such .lateral inclination while still having the tensioning action on the upper exerted in a Adirection extending substantially heightwise of the last. The gfrictional drag onthe zupperwill, of course, be slightly more eiective at the Vlower end of the roll because 'of its greater peripheral speed. However, since .this action is frictional, the :topedge ofthe lasting margin can readily adjustitself to Athis condition, and this self-adjusting :action can be augmented by modifying the shape `of the operating surface' 314, as already explained.v
The action of the roll frictional, the operator holds the .shoe against feeding 'for an instant and yuntil the upper has been tightened 'by the Iheightwise ycomponent of the roll stress and then permits it to be fed valong by the len-gthwise or 'feeding component thereof. Just assoon as the shoe starts to move, under the feeding action of .the roll drag, the other treadle is released, 'thus permitting spring 260 to lower the rotating wiper M and urge it yieldingly againstzthe .lasting marginA of the upper as. it emerges from the leaving side Yof the roll 'and sleeve. The operator now permits the shoe to be fed 'along by the roll drag while holding it against the edge l,gage I9!) -and swinging it so as to maintain substantially the same relationship ofthe As will be apparent the lasting'V-ma'rgin ofthe upper.
edge of the shoe bottom to the operating parts as is shown .in Fig. 6, i. e., with the entering rside 2 of the roll and sleeve `just about atthe redge of the shoe bottom and the leaving side well mover the shoe bottom.
4With the -rnoded sleeve construction, mentioned above and shown in Figs. 9 and 10, the ac` tion of the Aroll on the work is essentially the same, as just described. However, because of the de-r crease in the pressure applied lto the lasting margin near the upper part of the roll, the major part of the-frictional .drag is applied low down on This arrangement, as already explained, permits self adjustment of the outer -edge of the lasting margin and prevents wrinkling. By providing a relieved portion rat 3,15, the tensioned lasting margin is freed Y sooner for the action ofthe wiper while still being guided, and held, inwardly over the shoe bottom by the .surface 345 and roll I0. As the shoe thus moves along, successive portions of the upper pass between the rol-l and sleeve where they are tensioned and idrawn in over the bottom of the shoe. As the upper leaves the roll and `sleeve it is pressed firmly against the shoe bottom and wiped inwardly by the wiper I4. The lasting margin of the upper having been previously coated with a suitable adhesive, the action of the wiper results inthe upper being secured in lasted position on the insole I on the bottom of the shoe. Y l
Referring to Fig. 6, it will Ybeseen that vthe operfA ating surfaces 2I4 of the wiper teeth 2I3 Yhavea continuous in-wiping action, romlthe edgeo the shoe bottom inwardly. Also, their inclined lead# on the upper being wholly ing edges extend at an angle to their line of movement. Accordingly, the upper, as it leaves the roll I 0 and sleeve l2, is smoothed down nicely and with a wiping action which has a component operating in the direction of feed. The edge gage roll is so located that it bears against the upper up close to the insole and just about below the point where the influence of the roll ceases. Thus the pressure of the edge gage roll |90 does not interfere with the tensioning of the upper but instead is applied at the proper point to hold the tensioned upper against loosening before it is engaged by the wiper. Also, withthe edge gage roll contacting the edge of the shoe near the insole, it will hold the shoe properly positioned at all times as the lasting operation proceeds around the shoe.
The illustrated shoe is to be lasted all the Way around its edge and when this lasting operation has been nearly completed the operator depresses the roll and sleeve-controlling treadle, just before `the previously lasted portion of the upper is close to one of the previously lasted portions as possible and would finish when the other previously lasted portion was reached. The action of the wiper extends beyond both the starting and nishing points so that a smooth junction is obtained at each place. Also, the heightwise stress that is exerted by the roll on the lasting margin y of the upper will be transmitted to adjacent portions of the upper on either side of the point at which the roll is at any instant operating. Accordingly, in operating all the way around the shoe. although the roll and vsleeve are separated just before the lasting operation is completed by the wiper, as above explained, all parts ofthe upper will be tensioned and the sameis true where the lasting operation is started and finished adjacent to previouslylasted portions of a shoe.
As has been previously mentioned, the action of the roll I0 on the upper is wholly frictional so that the feeding movement of the shoe is entirely under the control of the operator. That is to say, he can hold the shoe fixed and let the roll slip over the upper. and he does so at the beginning of the lasting operation. Also, if during the progress` of the lasting operation it is desired to slow down the lengthwise feeding movement of the shoe, as, for example, to prolong the heightwise pulling action of the roll at any particular point or to facilitate the passing of any irregularity on the shoe bottom by the shoe rest 300, the operator, by overcoming the feeding component of the frictional drag, can cause the roll to slip until the desired length of pull has been obtained or the irregularity on the shoe bottom passed. It will be understood that while the roll is thus slipping and the feeding of the shoe arrested, the heightwise component of frictional drag is still being exerted on the upper. The relative intensities of the tensioning stress component and the feeding stress component of the frictional drag on the upper may be varied to suit different operating conditions by loosening the nut 82 and changing the lengthwise inclination of the roll I 0 and sleeve I2, as viewed in Fig. 5.
Fig. 8 shows a section of a shoe after it has been operated upon by thismachine, but instead of the shoe shown in Figs. 5, 6 and 7 a diierent type` of shoe is here illustrated. In this shoe the upper U is seWed to a sock lining S and-to a binding B previous to its being assembledy on a last L'. After the last L has been inserted into the upper U', a platform sole P is cemented in place with the binding in the dotted-line position shown. The inside face of the outstanding binding is now coated with a suitablecement and the shoe presented to the machine ,ofk this y invention, in which the binding B is tensioned so as to bring it snugly in against the edge of the platform sole P and drawn in over the shoe bottom and pressed iirmly into the full-line position shown. While, strictly speaking, the operation of this machine on a shoe of this type is not a lasting operation, no tensioning of the upper U being involved, it is clear that the action ofthe roll l0 and sleeve I2 and alsothe wiper I4on the binding B is in allrespects analogous to lasting as this term is understood in thetrade. Accordingly, in the appended claims, where the terms lasting and/or upper are used, it is ,in-
tended that they be given a broad interpretation lso as to apply to the tensioning, drawing-in, and wiping down on the shoe bottom of anyshoe part, such as, for example, the binding of a platform sole.
When used for lasting the uppers, or platform bindings, of shoes the bottoms of whichfare not substantially flat but, instead, have curved portions, such as, for example, steep shanks, scoop heels, etc., the alternative rotary wiper construction shown in Figs. 12, 13 and 14 may be preferred. Referring to these figures, the wiper 410 comprises an elongated cylindrical member or roll provided with axially directed grooves 4|2 which interrupt and separate its peripheral surface into a plurality of sections 4i4 terminating in edges 4l3. This roll is journaled in ears 4|6, 4| 'l extending downwardly froma bracket 4l8, at one end on a reduced portjon 420 and at the other end by means of a'stud 422. This bracket is secured by means of a nut 426, to a post 424, which is slidably mounted in an elongated boss 428 that projects down- Wardly from a mounting plate 430. The mounting plate is secured to a supporting arm 43'4, that corresponds to the wiper-supporting member 234, Figs. 2 and 4, and which is attached to the machine frame I6 by bolts 432, in such a Way as to be angularly adjustable about the axis of the post 424 by means of screws 436 that are threaded into curvedextensions on the arm 434 and which pass through arcuate slots 438 in the plate 430. A
'I'he bracket 4|8 is urged downwardly, yieldingly to hold the wiper against the shoe bottom, by means of a compressionv spring 440 which' is interposed between the top-of the bracket and an adjustable abutment nut 442 which is threaded onto the lower part of the boss 428 and provided with a lock nut 444. The post 424 extends some distance above a second boss 446 on'the plate 430' and its upper end is threaded to receive a stop nut 448, and its companion lock nut 450, for limiting the downward movement of the bracket and wiper by the spring 440. Themounting plate 430 also carries a support 452 vfor a stop screw 454, provided with a locknut 451i,l for limiting upward movement of the wiper 4I!) and its supporting bracket 4| 8.
The wiper is rotated, in the direction of the tical dimensions.
arrow, Fig. 12, by means of the belt 210 which, through a pulley 458', drives' a vertical shaft 460 that is connected to the wiper by means of bevel gears 462, 4'64. This shaft is journaled at its In FigllZ' the wiper` 4NI and its bracket 418 thev axisof post' 424 ywith the parts in iront oi the section shown in broken4 lines. These parts are, however, illustrated in full linesv in Fig. 14, i from which it will be seen that the ear AIT is Vremovably secured to the' bracket 418 by means of screws 30'. This arrangement makes it possible to remove the wiper #I by' unscrewing the stud` 4-2-2, taking offithe ear 4II`, and loosening a setscrew 482'Y which holds the bevel gear 464 von` the inner reduced end of the wiper.
In Fig; 12' shafts 424 and 460 are broken to permit thisl view to be foreshortened inV its ver- I Also for the sake of clarityl the slide i00- is' shown only in part,'and its guide blockA IUZ, together with other associated parts, are entirely omitted' from Fig. l2. Thev position of the guide block is indicated by broken-,lines in Fig; 13 andv it will be understood that the arm 34 is located above the block I U2 and that this arm, as well as the rearwardly extending portion of the plate 430, which carries the bearing boss N6, arez suitably shaped to provide adequate clearances for the sleeve-operating leverA I I6.
Withy this alternative wiper construction it has been found unnecessary to provide for elevating the wiper at the/beginning of each lasting operation and, accordingly, no operatingVv connections yfrom the vwiperelevating lever 25D, Fig. 4, have been shown. It will, of course, be understood that, if desired', such a connection could be readily provided by simplyextending. a link between the bracket 4 f8' and the end of the lever 2.50'. Under some operating conditions it may be desirable greatly to limit, or even prevent, up and down movement of the wiper, and this may be done by appropriately setting the stop nut M8 and stop screw #54, and the pressure of the wiper against the `work` may, of course, be regulated by varying Vthe force applied by the spring 44.!)- through ad- .lustment of the nut 44,2.
Referring to Fig. l2, the machine with `this alternative wiper construction operates to tension, overdraw and feed the lasting margin'M" of the upper of a shoe on its last L" yin exactly the same manner as described above, and the wiper operates to lay the tensioned upperV down 011 and to press it against, the bottom of the insole I", in substantially the same manner as the disc-like Wiper I4, i. e., with a continuous wiping action directed inwardly from, and at an angle to, the edge of the shoe bottom. As can be seen edges M3 correspond in action to the surfaces ZIA' and leadingv edges of the disc wiper, that is to say, the leading edges, in each case, Wipe the lasting margin inwardly and with arcomponent` Yof movement extending lengthwise of the shoe,
so that the upper is smoothed down nicely. Howevelg, the cylindrical roll-type wiper the component of movement lengthwise of' the shoe is 1 are shown in section on a plane passing through l of a shoe on a last as first to tension the upper Yl'ieightwise of the last, then to draw the tensioned upper in over .the bottom yof theshoe and also to y vbeen previouslywiped down.
6 l y :agences nthe other hand, the inward component ot wipe vviewed in Fig. 1-3, the inward component will be diminished and the lengthwise component increased and' an opposite effect will be produced ii the axis of the roll is swung in a counterclockwise direction. Also, the grooves 4 IZlmay be out atan angle to the axisY of the wiper in such a way as either to increase or decrease the inward wiping component.
Aside from this flexibility of action inherent in the cylindrical roll-type of wiper there is another and equally important advantage obtained. As mentioned above, thisv type of wiper is especially adapted for operating on shoes having curved bottoms, and such a shoe is illustrated in Fig. 12. Reference to this ligure will show how readily the small diameter cylindrical wiper nts onto a curved` working surface without interfering at all with portions of the lasting margin that have It willV also be apparent that in following a curved `shoe bottom the shoe may be held to maintain its bottom, at the point of operation of the lasting/roll I0, nearly horizontal, without disturbing the action of the wiper which can assume different vertical positions and thus accommodate itself to different 'operating levels.
