"The invention is herein illustrated as applied to a'power-operated toe-lasting machineof'the-Same general charactor as disclosed'in-United States Letters Patent No.'2,l34,148, "granted on'October 25,1938, on an application of mine,but modified in certain 'r-espects as further disclosed particularly in Letters smoothly inward over the insole; The :retarder comprises a pair of upper-clamping fingers which are moved "bodily lengthwise of the shoe with swinging movements also widthwise ofztheshoe to spread the margin of the upper fromover the insole and are thenmoved heightwisc of the shoe toward the-wipers into positions to cooperate with them in the upwiping operation.

I Machinesconstructed as above briefly described have been used withi'highly satisfactory results in operating on shoes'of various styles and of different materials. In operating,'however,'onmens shoes having comparatively "heavy uppers there is sometimes a tendency forlooseness or wrinkling of the upper to develop at the sidesof the toe near the tip line adjaccnt'to portions of the upper which have already been lasted or at least pulled over and fastened to the insole,"'by reason'of a Patent No. 2,138,308, granted on November 29; 1o tendency'for the wipers to deflect portions ofithe .1938, and No. 2,140,652, granted on December 20, upper'near'the tip line'in a-heelwarddirection as 1938, also onfiappli'cations of mine.

In'viewo'f the'discl'osures in the previously mentioned: Letters Patent, only as much of the machine "as itis necessary to refer to for an understandingiof the invention is shown in the drawings and will bedescribed in detail. For wiping the toe'e'nd of the upper heightwise of the last and'for'thereafter wiping its margin. inwardly over an insole on thelast the machine isprovidedwith a pair of toe-embracing wipers 2 operated'ibymeansfully disclosed in the abovementioned Letters Patent No. 213L148. The shoe is positioned bottom upward for the operation of the wipers thereon and is clamped and held in that position between an insole-engaging holddown 4 and'a' toe rest 8 (Fig. 12). Arranged to cooperate with the wipers isa retarder comprising tWO upper-clamping fingers 8 positioned initially over'thetoe end of the insole in contacttherewith as illustratedby broken lines in Fig, l. In'the operation of the machine these fingers are moved lengthwiseof the shoe toward the end of the toe and are also swung apart to insure the spreading of the marginpf the toe end of the upper materials from over theinsole, and as soon as they pass the edge of the insole they are moved downwardly'toward the wipers so as to clamp 'the marginal portion of the upner outspread on the top of the wipers when the latter have been moved upwardly far enough to 'me'etthem, asillus trated in Fig. 12. As the wipers continue their upward movement to wipe the upper heightwise of the last the fingers 8 are lifted by'the wipers while: cooperating with After the upwiping movement of 'the wipers the shoe is forced downward a short distance by the holddown-4, and the wipers are then advanced and closed to wipe themarginal portion of the upper inwardly over theinsole. In time relation to 'these movements of the wipers the fingers 8 are movedfarther lengthwise of the shoe and are swung farther apart while still controlling the margin of the upper until the latter is withdrawn from between them and the wipers by the movements of the wipers. Thereafter, following partial retractive movements and second inward movements of the. wipers, a plurality of tackers lo are moved into tack-inserting positions beyond the edges of the wipers and j are then operated to drive tacks to fasten the toe end of the upper in lasted position. As thus far briefly outlined, the machine herein shown is intended tooperate in substantially the same manner as heretofore.

For purposes of this invention the machine is provided with a pair of auxiliary retarders comprising upper-clamping fingers l2 arranged to control the margin of the upper at the sides of the toe in locations beyond the fingers B in a heelward direction. The fingers I2 are hookshaped, as shown in Fig. '7, to render them more effective in spreading the margin of the upper outwardly from over the insole on which they rest initially, as illustrated in Fi 1, in locations spaced considerable distances inwardly from the edge of the insole. These fingers are formed on the inner end portions of arms I 4 which extend laterally of the shoe and, for a purpose hereinafter explained, are pivotally mounted at their outer ends for swinging movements heightwise of the shoe on pins l6 supported on outwardly extending bars IS. A spring-pressed plunger l9 ineach bar l8 tends to swing the arm l4 upwardly and holds it normally in a position determined by its engagement with the bar [8. Each bar l8 has formed therein a cam track 20 in which lies a roll 22 supported between the arms of a bifurcated member 24, these arms being far enough apart to permit limited swinging movementof the bar is axially of the roll 22 for a purpose hereinafter described. Each member 24 has an upwardly extending stem 26 journaled in an arm 28 (Figs. 1 and 2) extending rearwardly from the upper end portion of a slide 30. This slide is vertically .movable in guideways formed in a bracket 32 secured to and movable with the appropriate'one of a pair of vertically movable slides 34 connected together by a transverse crosshead 3'5 which carries the previously mentioned holddown 4 (Fig-'12), the slides 34 and the crosshead 36 corresponding to the parts identified by the reference characters 69 and 61, respectively, in Letters Patent No. 2,134,148. A vertical screw 38 extends freely downward through a lug 40 on the bracket 32 and is threaded at its lower end in the lower end portion of the slide 30. A spring 42 through which the screw extends bears at its upper end against the lower face of the lug 40 and at'its lower end against a shoulder on the slide 30 and thus serves to urge the slide in a downward direction, the downward movement of the slide being limited by engagement of the head of the screw 38 with the lug 40. The screw is held in a fixed position by means of a set screw 44 in the slide 3!]. The outer end portion of each of the bars I8 is bifurcated and carries a roll 46 mounted on a pin 48 in the bar. This roll rests on the upper surface of an arcuate guide rail 5|] secured by bolts 52 to the rear end of a rearwardly extending arm 54 formed on the vertically movable slide 34 at that side of the machine. When, therefore, the two slides 34 are moved downwardly at a predetermined time in the operation of the machine to cause the holddown 4 to depress the shoe, the bars (8 are moved downwardly with the slides. Through the springs 42 the fingers I2 in their initial positions are held downwardly on 7 the insole when there is a shoe in the machine,

and these springs are yieldable to permit :upward swinging movementsof the bars- I8 in response to .pressure of the upper :on the .lowerfaces of the fingers I2 when by the relative movements of the wipers and the shoethe wipersare caused to assume positions above the level'of the insole preparatory to the wiping of the margin of the upper inwardly over the insole.

Mounted on each of the pins 48 is the lower bifurcated end of a member 58 provided with a stem 58 extending upwardly through the front end of a forwardly extending lever arm '68 mounted on a pin 82 for horizontal swinging movements. It will be noted that the front ends of the arms 68 are far enough above the lower bifurcated portions of the members 56 to afford leeway for vertical movements of the slides 34 and the bars- I8 supported thereby. The left-hand lever arm 68 has integral therewith a rearwardlyextending arm 84 connected by a link 86 to an armGB in fixed relation to the right-hand arm 68. Through parts including the link '88, therefore, the two arms 88 are coupled together, the arrangement being such that swinging movement imparted to the left-hand arm 68 in a clockwise direction to move the left-hand finger I2 outwardlyover the insole will cause the right-hand arm 88 to swing in a counterclockwise directionandthereby to move the right-hand finger I2 also outward- 1y. For thus swinging the left-hand arm 68 the machine herein shown is providedwith a cam track I8 (Fig. 1) formed in the peripheryofa toaholdthe pin I88 in this position. At its front end portion the arm 9815 provided with a lug I28 connected to theleft-hand end of the previously mentioned link. I a From the foregoingdescription it will be understood that with the parts in their normal positions the cam-operated lever arm 82 is effective initial positions after having operated on a shoe, 1

nmdamage-Will result, since the pin I88 will wedge the arms 98 apart against the resistance of the spring-:96 and the arm'82will continue its movement without operating the arm 88;

- The manner-of operation of the machine; in

sojar. as it is of interest with reference to the present invention, will now be briefly suma inarizedr *Shortly after the starting of the power cam 12 fast on the left-hand end portionof a v shaft I4 (Fig. 9), this shaft corresponding to that identified by the reference character 258 in Let- I ters Patent No. 2,134,148. Lying' in the cam track is a roll 78 mounted on a rearwardly extending lever arm I8 which is positioned below the cam 12 and is arranged to swing about a vertical stud of the left-hand arm 68 for operating the latter.

The connections between the arm 82 and the link 84 are best shown in Figs. 4, 5 and 6. "Mount ed under the front end of the arm" 82 re swing aboutfpins 88 carried by the arm aretwo short arms 98 so formed as'to extend part way'ar'ound a boss 92 on the arm 82, this boss having thereinan arcuate recess 94. Mounted betweenlugs ex.

tending from the arms 98 is a spring 98 which tends to swing the arms inwardly toward 'each other. Extending forwardly from the stud '88 is an arm 98 which is mounted to'swing about the operation of the machine, the shoehavingbeen clampedxbetween the 'holdd'own' 4 and the toe resti'fi; then-lain retarder fingers 8 are moved rearwardly over the insole toward the end of the insole; whereupon they are moved downatthesides 'of'the toe beyond the fingers "8. In

their outward movements the fingers'l2 maybe deflectedlengthwise of 'the shoe toward the fingers 8by' the'action thereon .of inwardly exstud, and carried by this'arm' in}; location 'slubstantially midway between its front and rear ends is a pin I08 movable vertically in a herein the arm. Extending rearwardly from the pin I88 is a handle II8 forturning it. It will be evident,

that by turning the shaft I88 the pin I88 may be moved upwardly or downwardly. Normally the parts are so positioned that the pin: I88 extends' upwardly into the arcuate recess 94"o'f thebos's 92 on the arm 82, and in this positionit isalso engaged by inwardly inclined shoulders I I2 of the two arms 98. A tension spring I I4 (Figtjfiyconnected to a pin I I6 on the disk I88 and'tda pin "similarly to the fingers 8 near upwipin'g'op'eration.

It will-b'e'understood that after the upper is tending portions of the :margin of the upper which are'adjacent to. portions already lasted, tor, atle'ast pulled'over and-fastened to the insole; just'be'yond, the .toe portion of theshoe. In this manner the fingers I2. ar-e maintained near the. ends of the fingers-:8, so that control ,of' the margin of the upper will besubstantially continuousx all along the sides of the toe. It will be understood that such deflection of the fingers -'I.2--*lengthwise of the shoe is permitted by'the provision for "swinging movements of the bars -|eai ia11y of the rolls 22, as hereinbefore described. Just before the wipers 2 completetheir upwiping movement the inner end portions of "the =fln-gers'l2 arrive'in positions where they are over, the' edges ofv the wipers, as illustrated in FigQI O, to render them effective to clamp the;

margin of the upper outspread on the wipers the end of the first clamped on thewipersby the fingers '8,"-as

snsw'n in Fig. 1-2, further upward movement of 'the wipers serves to lift these fingers, the wipers 1 I8 -on the arm as servesby its action on the disk over or side-lasted ortions.

' ther outward movements. I

.tackers in their downward and inward moveand the fingers cooperatingto apply an upward pull 'to' the upper in the upwiping operation. Immediately after the upward movement of the wipers the shoe is depressed a short distance by the holddown 4, thus causing the wipers and the fingers 8 to apply a further pull to the upper and positioning the shoe in proper'relation to the wipers for the latter to wipe the marginal portion'of the upper inwardly over the insole. As the shoe is thus moved downwardly the downward movements of the slides 34 which carry the holddown result in further compres sion of-the springs 42 which control the bars l8 and the fingers I2, thus increasing the clamping pressure of the fingers on the margin of'the upper over the wipers.

As thewipers are advanced and closed to wipe the upper inwardly over the insole the fingers 8 are moved farther rearwardly and are swung farther apart while clamping the margin of the upper on the wipers until the upper is withdrawn from under them by the wipers. At substantially the same time the auxiliary fingers I2 are moved farther outwardly while similarly controlling the margin of the upper at the sides of the toe beyond-the fingers 8 (Fig. 11). manner the fingers I2 cooperate with the fingers 8 to counteract any tendency for the upper at the sides of the toe to be deflected in a heel ward direction by the wipers in such manner as tocause any loosening or wrinkling of the upper in locations adjacent to the previously pulled- A machine such 'as'that to which the invention is herein shown as applied comes automatically to a stop when the wipers are at the end of their overwiping movements to permit the operator to inspect the work, and when the machine is again started the wipers are partially retracted and are then moved'short distances inwardly once more prior 40 to the fastening of the upper in lasted position. In time relation to this second inward wipe the tackers II] are moved into tack-inserting positions just beyond the edges of the wipers and are then operated to drive the tacks; After the secand starting of the machine the auxiliary fingers I2 are moved still farther outwardly and by the action of the rolls 22 on the bars I8, by reason of the shape of the'cam tracks 28, the fingers are swung upwardly away from thewipers to: avoid interference with the latter intheir fur- In case any of the ments over the I wipers toward tack-inserting positions should strike against the fingers I2 the latter may swingdownwardly against the resistance of the spring-pressed plungers I9 to avoid any danger of damage to the machine.

'When the fingers I2 are moved inwardly to'their properly with the wipers in the manner above described in operating on shoes of diflferent widths, provision is afforded for variably timing the outward movements of the fingers over the, shoe, so that they will arrive in positions over the edges of the wipers, as illustrated in Fig. 10, at substantially the same time relatively to theupwiping movement of the wipers in operating-on a narrow shoe as in operating on a wide shoe. For

In this this purpose thereis mounted on the shaft I4 (Fig; 9) for adjustment lengthwise of the shaft adjacent to the cam I2 a segmental member I88 which carries a hardened wear piece I98 arranged to serve as a portion of the left-hand wall of the cam track H1 by which the fingers I2 are operated A pair of springs I92 mounted in the hub of the segmental member I88 tend by engagement with the hub of the'car'n to move the segmental member outwardly along the shaft. Threaded on the end of the shaft is a hand wheel I94, and fastened by bolts I96 to the inner side of this hand wheel is a hardened steel plate I98 arranged to bear on the hub of the segmental member I88. By turning the-hand wheel, therefore, the position of the segmental member and of its wear piece I98 may be varied to vary the timing of the first portion of the outward-movements of the fingers 12 as and for the purpose above described. Such an adjustment of the segmental member will be made when the wipers are changed preparatory to the use of the machine on shoes of a different size. In the steel plate I98 are a pluralit of recesses 208 arranged to receive a springpressed detent 282 mounted in the hub of the member" I88 to hold the hand wheel I94 in ad'- justedposition.
