and lisherein illustrated ,as applied to Va heelend ylasting machine of the""type` disc1osed` n United States Letters Patent No.` 2,059,241, granteden'` November 3, 1936, on an applicati'o'nof mine." Itis to be understood, however, that the invention is 'not limited'to machines of that particular` type andthat in various novel aspects also it is notlimited to machines for lasting the heel `en"ds`of`shoes as distinguished from the toe ends.` l jThe invention has especially in view *the* provision of "improved" means for lastingthe heel endsoi fshoes of that 1kind in lwhichawelt is applied around the heel end as well asy at` other portions "and "in whichthe margin ofgthe heel end" of' the upper is lasted against a welt-attaching lip ontheinsole." *A ,machine of the: abovementioned` `type is provided" with wipers `for wiping "the marginal portion ofthe heel end upper `is lasted against a lip on the insole it is desirablethat the contourof thewiping edges of the wipers correspond as nearlyJ as "possible to "the contour offthe lip ofthe insole lengthwise of"the"edge ofthe shoe bottom, and accordingly ,y
different' wipers need to be used on shoeslthat differ substantially in style orsize. It is also desirable lthatthe severalffastenings be driven at `substantially `uniform distances from the lip oftheinsolei The present invention accordinga lyyprovides ajinovel construction such that the .Wipersmaybereadily `detached from their movl able supports to permit diierentwipers` to be substituted, and `such thatthe same fasteninginserting "devices are used with `diiierent` wipers butv-assume different relative positions determined by the different Wipers. `Irrthe construcv `tionslfiown each of the Wiper supports carries a" plurality'of lfastening-inserting `devices `so mounted `thereon as` to permit them, when the g `Wipers are detached,4 tofswingrelatively to one another i in* such `directions as to vary relatively the rpositions of fastenings `inserted respectively by `the different devices,and the wipers when in place ntheirsupports interlock with the fasa,
tening-inserting devices and maintain themin a relation tofone another appropriate for the contour of the wipers. The wipers, as more particu-v larly hereiniilustratedam guided tomove in 35 claims. (ci. 12V- 4) l predetermined `curved paths to mount themen or `detach them `from their supports, and are provided with grooves arranged to receive successivelyrfthe different fastening-inserting ,devices associated therewith.` as the fwipers fare `moved into place on their supports.` Preferably, as shown,` thefastenings are driven only part Way into the shoe, so thatrthey may be conveniently removed at a later stage inthe manufacture of the `shoe,a`nd the-Wipers are so formed that the holes through which the iastenings are driven `are open toward the inner `edges of` the wipers throughout" a portion ofl the thickness rof the wipers to provide clearance for the upstanding portions of`v the fastenings when the `wipers are retracted." i
`The invention further,` provides novel means for supportingthe lipof the insole against inward "pressure in thelasti'ng'T operation. "A mai chine ofthe type shown in the above-mentioned Letters `Patent is provided `with a holddown which engages the heel end of the insole todetermine the position of `the shoe heightwise Jrelatively to'thewipers,` the `holddown being movable automatically in the power 'operation o f the mai chine todepress the shoe relatively tothe wipers and thus to relieve the pressure of the Wipers on "the'upper afterithe lasting operation.` For purposes of this invention, the construction herein shown comprises lip-supporting meanswhich is mounted on the holddown and is movable by the operator relativelyto the holddown into lipsupporting positionlprior `to the starting of the power operation of the machine. More particularly, theflip-supporting'means comprises members` movable relatively to each other widthwise ,offthe' last into supporting relation to the lip at the sides of lthe insole,` and a carrier for these membersmovablein'a path inclined lengthwise and f heightwise of the' last to carry the members i into engagementwith the insole and into supportingfrelation` to the lip at the extreme end ofthe insole. The carrier is lthus moved by a lever whichiby further movement serves to swing the `lip-supporting members apart into supportying relation to the lip 'at the sides of the insole. A` device `is further provided` for holding the lip-supporting means in operative position and for releasing` it` in response to theabove-mentioned `automaticmovement of the holddown after the lasting operation to permit itsrreturn to starting position. i

As disclosed in the previously mentioned Letters Patent, a machine of the illustrated type is y provided with a shoe support or jack (not herein shown) vwhich is movable prior to the starting of a and up against the holddown and the heelband is closed about its heel-end portion, after which the margin of theheelend of the upper is wiped inwardly over the insole and is fastened thereto by the driving of a plurality of lasting tacks.
For wiping the margin of the heel end of the upper inwardly against a lip on the insole, in operating on a shoe of that type in which'a welt is applied around the heel end, the machine herein shown is provided with a pair'of wipers 6 the construction of one-of which is clearly illustrated in Figs. 5 and 7. It will be understood that the two wipers are alike except for such differences as are necessary to permit them to be mounted in the machine for use respectively on the opposite side portions of the heel end of the shoe. The wipers 6 are detachably mounted on wiper supports or holders comprising blocks 8 which, although differently constructed in certain respects, are mounted in the machine and are operated in the same manner as the blocks 404 shown in the previously mentioned Letters Patent. That is, each block 8 is detachably secured to a member I0 guided for swinging movements laterally of the shoe on a slide I2 which is movable lengthwise of the shoe, the members I0 and I2 corresponding respectively to the cam-operated members 4IB and 42|) shown in the above-mentioned Letters Patent. It will be understood that the slide I2 is operated to advance the wipers bodily lengthwise of the shoe and that the members IIJ are operated, through links I4 (Fig. 3), to swing or close the wipers inward laterally of the/shoe in a horizontal plane in they course of their advancing movement.
For-use in lasting shoes of the illustratedk type the cams ,with which the machine is provided for thus operating the wipers are so formed-as to impart to them movements shorter than heretofore, to wipe the upper over the feather of the insole and to press a portion of its margin in upstanding position against the lip of the insole, and are also formed to move them inwardly only once instead of twice in the cycle. Since for the best results the inner edges of the wipers should be curved similarly to the llip around the heel end of the insole, `the wipersare so .mounted on their supporting blocks 8 .that they may be readily detached therefrom to permitY diierent wipers to be Used for shoes of different sizes or styles.. To this end, as ilustrated in Fig. 7, each wiper is provided with a curved groove I5 formed to receive a dovetailed tongue I6 (Fig. 5) on the lower face of the supporting-block 8, so that the wiper may be readily detached from the 'block and another wiper mounted on the block by sliding it along this tongue in a curved path. When the wiper is in proper position on the block it may be fastened thereto by any suitable means such as a screw (not shown).
After the upper has been wiped into lasted position by thewipers it is fastened temporarily by driving a plurality of tacks in the angle between the feather and the lip of the insole in the manner illustrated in Fig. 6, the tacks being driven only part way in so that they may be conveniently removed at a later stage in the manufacture of the shoe. For thus driving the tacks thereare associated with each of the -wipers a plurality of tackers I1 which are relatively adjustable to permit them to assume different positions as determined by different wipers mounted in the machine, so that in operating on shoes of different sizes or styles the tacks will be driven in as close relation as is practicable to the lip of the insole. Each tacker comprises a block I8 mounted in a vertical slot I 9 (Fig. 5) in the block 8 and having an outwardly extending portion provided with holes to receive studs 20 (Fig. 3) projecting from members 22 fastened to the block 8 at opposite sides of the block I8. In thismanner the several blocks I8 are so mounted as to permit their lower ends to be swung inwardly or outwardly when there are no wipers in the machine. These lower ends. of the blocks are arranged to enter grooves 24 formedin the wipers in locations between the grooves I5 and their inner wiping edges when the w'ipersiare moved into place fori theirfsu'pporting blocksi, `sothat the several tackers assume "positions` `determined by contourof the wipers. ,Asjillustrated in Fig. `5; the lower ends of the lblocks I8 lare preferably spacedl somewhat a'bove the bottoms of the grooves 24, butfportions 25 of the blocks 8; which" are narrower than the grooves, `extend to lthe bottoms f thev grooves to assist in supportingthe wipers firmly against upward pressure of the shoe upon them. l
`In` the `constructionherein-shown each tacke'r l'I is formed to drive a"pair oftacks through holes `2li in the corresponding"wiper;` For this purpose each block I8 has `a circularY bore 28 rthewipers' andjappropriate for theparticular (Fig. in which `operates a driver bar 36 `proi vided atv itslower" end with" two tack drivers 32 movable in driver passages formed partly in the block Iiand partly in a plate 34 fastenedto thel block. The drivers 32 are `mounted vin' sockets in thebar 30 fand are heldin placeby` a pin 35, asillustratedin Fig. 9. Mounted for turning movement in the block I8 and the plate 34 is a tack holder 36 (Figs`j5 and 8)" of generally cylin-` drical contour provided with vrecesses 38 which serve as tack pockets associatedwith the respec-` tive driver passages `andl into which tacks are delivered at the proper time through passages 40 in the b10ck`1I8. i `Tacks are coiiductedfto the passages 40 through flexible tubes 42 from tacksupplying mechanismconstructed as disclosed in the previously mentioned Letters Patent.` Extending into the two recesses 38 in thetack holder` 36 are flanges 44 (Fig. `8) `of the plate 34, in
V which flanges portions of the above-mentioned driver passages are formed. A spring 46 `tends to turn the tack holder 36 in a counterclockwise direction, as the `parts aretviewed in Figs. 5 and 6, and maintains it initially in awposition determined by engagement of `edges formed thereonati the lower ends of `the recesses 38 with` the flanges 44. When theitack holderf is in this position the lower'` ends of` the ShanksA of the tacks controlled thereby extend `short distances `belowthese edgesv in `engagement with the'wallsl of thedriver passages, as illustrated in Fig. 5, the `Shanks ofthe tacks lbeng inclined relatively to the paths of movement of the driv` ers 32 and inwardly inclined relatively to Athe edge of the shoe bottom. The driversq32 have lower end faces inclined similarly. tothe corresponding` inclinations ofthe heads of `the tacks, and` accordingly the tacks are driven yinto the shoe at` inclinations `substantially the same `as they occupy when inthe tack pockets, the points l of the tacks beinge'uidedfduringaportion of the inner edges of` the wipers to provide clear;
ancefor `the heads of theupstanding tacks when the wipers are retracted. For the purposey of leaving the tacks upstanding the operative movements of thev drivers are limited by lmechanism provided in accordance with the disclosure of the previously mentionedLetters P'zaterit.V lnview of the multiplicity of the "driver4 bars 30; the construction herein llshownvincludes, f for operatingv theseibars, a plate '48 '(Figsnliand) havingk therein a"plurality of guideways 50 curved similarly to thepathsof movement ofrthef "wipers,V in which: guidew'ays' lie ilanged heads '52 formed on the upper ends ofl the` driver bars 30.l By
reason of this construction 'ther driver `bars are moved downwardly and upwardly `by corresponding `movements ofthe plate48 and `are permitted to movewitlr thefwipers while maintaining their operative relation to the plate nThef`plavtei48 is operated at the proper time through a link 54|wli`ich corresponds to the link1564shown in the previously mentioned Letters Patent; i
`The previouslyl mentioned holddown 4 `comprises a slide'56 (Figsfland10)-which is` verl-1 tically movable in ai g'uideway in the frame 53 like ithe `1member2504 shown in the' previously mentioned Letters `Patent C 'and is automatically controlled inthe power operation of the' machine through a cam-foperatedipinion in engagement with i rack teeth formed on the slide. "In" the constructionhereinf shown thevlower end ofthe `slide 56` is so shaped `as to provide a holddown foot 62\`(Figs. 1 `andlZZ) whichziscomparatively narrow widthwiseof the shoe and the lower edge of whichvisuarranged` to Vengage the heel-end portionf of the insole` when the shoe ismoved upwardly by the shoe support, as I hereinbefore described, prior toi-the starting of the power operation .of the fmachine. Thisupward movement` ofthe shoeserves'to impart a short upward movement to the slide 56, asand for purposes described in the above-mentioned Letters PatentiH Ashistingushed Afrom the prior construction; the cam (not shown)` for `operating the pinion 60 `is preferably soformed that `when the slide `56 lhasbeen thus lifted prior to thestarting of the power operation ofthe machine the shoe is `at the properiheight for the wipers to operate thereon,` andfthereafter `the slide remains .sta-
tionary until` itl is moved downwardly a `short J distance to` depress thetshoe and thus to relieve thepressureiof the Wipers onilthelupper after the `tacks have `been driven,` such depression of theasho'e further insuring `that the` heads of `the tacks will clear the wipersi when the latter are retractedij .i i I i M `lurther to `accomplish the objects of the present invention, the holddown 4 has associated therewith means Vfor engaging the inner `face of the lip ofbtheinsole` aroundthe heel'end of the insole `andfor supportingthellip against the inward pressure of the wipers. This lip-supporting means comprises a pair -of arms 64 (Figs. 1 and 12) lthe `outer faces? of which are curved in general similarity touthecurvature of the lip of the insole, the twoarmsl beingpivotallylmounted at Jtheirireariendson afpinsGB supported by'a slide 68 `which serves as "a carrierfor'thearms.
The `slideli` is'supported on the lower end of the holddown slide 56, so `that itl moves upwardly and downwardly with `the lattenand it is also mounted formovement relatively to the slide 56 in an inclined` path extending `heightwise and lengthwise ofthe shoe. For `thispurpose there is'fastened" to thefslidef56 by bolts -10 a bracket "I2 whichis bifurcated to extend along opposite sides of `the slide'ssfme forks of the `bracketbeing l provided Awith inwardly 'extending flanges, a por` tionfof one of which is shown in section at I4 in Fig. 1, extendingintoygrooves 'I6 formedin opposite side `portions of the "slide, 68. The
angesM and the groovesj 16 are. inclined as illustrated, so thatv by .movement of ther slide 68 in one direction the lip-supporting arms 64 are carried both downwardly toward the insole and rearwardly toward the portion of the insole lip which is located at the extreme rear end of the insole. i For moving the slide 68 in that direction and also in the opposite direction, there is pivotally mounted on a pin 18 on the slide 56 a bell-crank lever 80 one arm 82 of which has a rounded end extending into a recess in the slide 68 and the other arm 84 of which carriesoa pin 86 extending into slots 88 formed in a bifurcated rear portion of a block 90. The block 90 is mounted on a vertically movable rod 92 and rests normally on a shoulder 94 provided by an enlarged lower end portion of the rod, this portion of the vrod being guided forvertical movements in the. front end of the bracket 12. Between the block l90 and another block 98 which is fastened by a 'transverse pin |00 to the rod 92 is a spring |02. Accordingly, in response to downward movement of the rod 92 and the block 98 force is transmitted yyieldingly through the spring |02 to the block 90 and the bell-crank lever 80 to move the slide 68 in a downward and rearward direction and thus to carry the lipsupporting arms 64 rearwardly against the lip of the insole and against the bottom face of the insole adjacent to the lip. For thus operating the rodv 92 there is provided a hand lever |04 the rear end of which is rounded and lies in a recess |06 in the frame 58. The hand lever |04 is provided with an opening |08 into which the block 9B extends,` and it is pivotally connected by the pin to the rodl 92 and the block 98. Downward movement of the rod bythe hand leverV is effected against the resistance of springs ||0 which are connected at their upper ends to the frame and at their lower ends to sleeves H2 threaded on the opposite ends of the pin |00. By these springs the rod 92 is maintained initiallyin such an upraised position that the slide 68 and the arms 64 are forwardly and upwardly retracted from thepositions which they occupy in Fig. 1', the holddownv foot 62 extending somewhat farther downwardly than the arms, as
shown in Fig. l0, foriengagement with the shoe when the latter is lifted by the work support. It will be observed that the foot 62 extends downwardly through a slot ||4 (Fig. 12) in the slide 68, this slot being sufliciently elongated to permit the required movements of the slide.
The lip-supporting arms 64 are positioned in proper relation to the lip at the opposite sides of the insole by swinging them outwardly about the pin 66. For this purpose the vfront ends of the arms are connected by links I |6 to a small block ||8 which'is itself connected by a pair of links |20 to a lever |22 pivotally mounted on a pin |24 supported in forwardly extending lugs |26 formed on the slide 68. The lever |22 is engaged by the lower end of the rod 92, so that by its downward movement this rod acts through the lever |22 and its connections with the arms 64 to swing these arms outwardly against the lip of the insole. This movement of the lever |22 is effected against the resistance of a spring |28 which is seated at one end in a recess in the slide 68 and surrounds at its other end a short stud |30 projecting from the lever |22. It will be understood that the spring |28 serves, when permitted, to swing the arms 64 inwardly toward each other, so that it maintains them initially in positions comparativelyclose to the opposite sides of the holddownfoott 62, Vas illustrated in Fig. 10. The construction is such that the downward and rearward movement of the slide 68 is stopped by the engagement of the insole with the arms 64 before the arms have been swung fully outward to their lip-supporting positions, after which the spring |02 yields as the hand lever |04 is moved farther downwardly to move the arms into those positions.
The lip-supporting arms 64 are moved into supporting relation to the lip of the insole by the hand lever |04, as above described, after the shoe has been moved rearwardly and upwardly by the work support against the heel band 2 and the holddown foot 62, but prior to the starting cf the power operation of the machine. To permit the operator immediately to release the hand lever |04 after operating it, mechanism is provided for maintaining the arms 64 in the positions to which they are moved by the hand lever by locking the rod 92 against reverse upward movement. For this purpose there are mounted in a recess I3| (Fig. l) in the frame 58, through which recess therod 92 extends, three brake shoes |32 which substantially surround the rod, as illustrated in Fig. 2, these brake shoes having conical outer surfaces which are engaged by a complemental surface formed on the interior of a bushing |34 also mounted in the recess |3I. This bushing is held normally down against a plate |36 fast on the frame by a comparatively heavy spring |38, and the three brake shoes |32 are forced upwardly against the interior face of the bushing by lighter springs |40, one for each brake shoe. Accordingly, the brake shoes do not prevent downward movement of the rod 92 by the lever 04, but they act as wedges between the rod and the inner face of the bushing |34 to lock the rod frictionally against reverse upward movement. Provision is afforded for upward movement of the bushing |34 against the resistance of the .spring |38 merely for safety, in case the Wiper-operating mechanism should be accidentally so adjusted as to close the wipers too far inward laterally of the shoe. In that event the lip-supporting arms 64 may be forced inwardly by the wipers and will act through the lever |22 to lift the rod 92, the brake shoes |32 and the bihing |34 against the resistance of the spring To release the rod 92 and thus permit the rod and the parts controlled thereby to return to their starting positions, there is provided a sleeve |42 slidingly mounted on the rod for downward movement to engage and depress the brake shoes |32. 'Ihis sleeve is threaded in a trunnion block |44 which is mounted in an opening provided in a lever |46 and is pivotally mounted on the ends of studs |48 threaded in this lever. The sleeve |42 is provided with a knurled portion |50 by which it may be turned to adjust it toward or from the upper ends of the brake shoes |32, and threaded on the sleeve is a look nut |52 arranged to engage the lower face of the trunnion block |44 to lock the sleeve in adjusted position. The lever |46 is fast on a rockshaft |54 mounted in the frame 58, and also fast on this rockshaft is another lever |56 one end'of which is arranged to underlie a lug |58 formed on the holddown slide 50. A spring |60 tends to lift the lever |56 and to maintain it in engagement with the lug |58. When the holddown slide 56 is moved downwardly to depress the shoe after the wiping and tacking operations the lever |56 is swung 112,280,152 i downwarmy ty `the iugilssz tofimpart .through the lever |461such downward; movementtothe sleeve |42 'as to depress the .ibrakeashoes` |32 and thus to lreleasethe rod 92,:` The\lever|46 isV provided with a handle |62 by which itmay be vswung downwardly by4 the operatorin caselit should be desired, prior to the starting'of the power operl ation of the machine, `to r'eturntlfie` lip-supporting arms B4 and permit them to bemoved again into supporting relation Ito theflip.
