To (LU 10710171/ t may colli-cern.
Be it known that I, HARRIE A. BALLARD, a citizen of the United States, residing at Boston, in the county of Suffolk and State of lifassachusetts, have invented new and useful Improvements in Machines for Tucking and '.lrimming Fabric-Covered nner-y soles, of which the following is a specification.
IThis invention has for its object to provide an improved machine for tucking a layer of fabric into `the channels of an innersole and for trimming' the fabric along the edge of the innersole, in the production of ,gem innersoles, so-called, and it comprises improvements in certain features of construction, relation andoperation such as hereinafter described. Those instrumentalities of the machine selected for illustration andV description as best exemplifying my invention, which operate directly on the work, comprise an inner tucking member or linger which is adapted to enter the inner channel and force the fabric thereinto, a memberl which engagesV and smoothes down the fabric on the feather edge, a presser-foot and a combined feeding and ytucking member or finger which are 'arrangedyto bear upon the work in alternation, and cutting members which are arranged to trim off the `surplus fabric on a line along the edge of the innersole. The presser-footis arranged for vertical reciprocation, whereas the feeding and tucking membersha-ve va fourway motion imparted thereto to effect a step-bystep movement to the Work. `In addition the inner tucking member is` so mounted and' operated that its operative end is caused to slide on and across the face ofthe innersole toward the inner wallV of the f lip Vor rib. lfurthei'morm it is located oppositev the outer tucking and feeding member (which vis arranged to force the fabric intol the rc- `entrant angle formed by the rib and the feather) so rthat thefabric-covered rib or lip is gripped between them, and thetwo instrumentalities maybe operated 4more lor less in unison bythe same power-transmitting member. .ln turning the' toe, it is desirable i that the length of the longitudinal feedil'ig movement of the inner tuckingmember .may
be reduced without affecting `the feeding n'unf'cment of the outertucking meinbe and Iprovide means, under manual control, by which this may be effected,l ,The edge of the thefworl: table).
`head of the vmachine and certain' of the innersole, as it `isbeing fed, is pressed aga-inst an edge gage whichV is so related lto the carriage for the trimming cutters that the latter are automatically adjusted tofo1 low the edge of the sole. The trimming cutters lpreferably comprise a pair of coacting edged disks, arranged to engage the projecting edge of the fabric in .proximity to the presser-footand the feeding and tuck? ing members, and having their axes inclined to the horizontal (for to the lplanevof the work support) so that th'efline of cutis slightly inside the edge of the feather. As a matter of construction,v the same-carriage,` which supports the cutters, is utilized` to support the member which presses down the fabric onv the yfeather edge in advance of its engagement `by the feedmember.

Vtowards and' from the main work support,
'the cazrr'lageL which supports the trimming Referring to Vthe accompanying drawings, the machin-e there illustrated comprises a suitable head 2() mounted upon a Vstani-lard 2l.- llpon thlis head are mounted the various operati-ng instrumen-talities with the exeepf tion of the foot treadles by which certain of the instrinnentaliities' are` under' manual control. The head is provided with a i'orwardly-projecting bracket terminating in an-nplright tubular bearing 22 in which the work table is mounted. Any suitable form ofsupport may be utilized' to receive the work and to permit it to be fed. The work table comprises a rotary disk 23* having av centralstem 2d ournaled in a sleevex25, which is mounted "tonie-ve vertically in a tubular bearing 22,
and which is held against rotation by a crosspin 26 extending into'slots 27 inthe. sides ofthe tubular bearing. The' sleeve 25 is provided' with flange 2`8f form' a housing, the upper edge of whiehlies in a pla-ne slightly below the upper facel ofthe dish 28.
The dish-F23 issnppo-rted near its outer edge by suitable anti-friction bea-rings which need not-be 'described in detail, as this is 'not an uncommon construction. The vpi^n2C secures to the sleeve 25- a rod29,to the lower end of which is' seen-red a chaino-r other conn-ection 30 extending downward-ly to a ioot treadle' (not shown), but which the operator may depressso as to lower the work support bifidi-ly.r The' lower end oft the rod 29 slides through a threaded sleeve 3l serewedf into the lower end of the tabular bearing 22 so as to be adjustable vertically The extremity of the rod 29 is n; spring is lo ated in t-he bearing, one end abutting vagainst the-flower end of the sleeve `and the other end abutting against the externally threaded `sleeve 3l so as to'iliorce the work support as a whole bodily iin-il the mit 32 engages-thefend of the slee-ve 3 llhe'upper' Y l 2"" may be radially corriaas will be explained. VThis supplementall table is provided with an edge rgage 38' against which the edge of the feather of .the innersole may be pressed by the operative.

Journaled'in` bearings afforded by the carriage, there are twoA knife shafts 44, 4 5, which are parallel to eachV other" but which are inclined at an ang-le of about l5o to the horizontal. These two shafts are lgea-red together by gears 46, 47, thegteeth of which are longenough to; permit a limited axial sliding engagement. On what in this case may be tei-ined the forward ends of' the shafts, are located coacting disk cutters LIS, 49, which slightly overlap each other, the front face of the cutter 4:9 being held against the fiat face of theciitter 48h51 a spring 5@ which 'encircles the shaft with one end bearing against the gear 47 and the other end bearing against a bushing in whiel'itheqshaft is mounted'. The latface offtheciitter ilSV'bea-r's against the' flat face 35 of the houstire carriage is drawn forwardlyT towards l the work support by a spring Figure 2), one end of which is attached to a pin onthercari-ia-ge andthe other end .of whichis attached' to a pin Bton the main frame or lreadi` .The'supplemental table 37 it'ormedon or secured-'fio a bushing 55 in which the forward end of' the shaft fill' is mount-ed, ,said bus-hing beingV secured of course to the carriage Elf. .lheupper face of the supplemental table may be slightly inclined downwardly and to the right,
viewed from the front end of the machine, as Vbest shonfnin Figure 7. Byreason-of the inclination of the sl1afts-44i,45, to the horizon-talgand the in,clina-tionl of the overlapping faces of thef disk cutters to the if'ertieal, the fabric layer on the innersole maybe cut inside of the feather edge of the innersole, this being in part determined 'by the location of the edgegage 38 on the supplemental' table. Normally the spring holds the'carriage yieldingly in a `forward positiontto theV leftin Figure so that the ,'frontedge of the Lsupplemental table engages the housing flange 28 withthe .flat 'face' of the cutter 48v vagainst or close to the front t'ace of said 'housing flange;
but, vas the work is fed (by meanst-o be expla-ined),` the 'engagement of-r they feather edge with the edge gage may :torcev the earri-age rearwardly, or to the right in vFigure 3, so that the cutters will trim the projecting 'portions of the fabric on a line conformable to Ythe edge of the innersole,
lll() lli Any suitable means may be utilized for driving the cutter shafts 44, 45. I have illustrated the machine as being provided with a main driving shaft 56 equipped with a pulley 57 by which it may be rotated. This shaft is journaled in bushings 58, 59, suitably located in the head or frame 20.- At 60 there is located a stud shaft on which is lionrnaled a gear 6l intermeshing with and driving a bevel gear 62 on the shaft 44. The gear 61 intermeshes with `and is driven by a gear 68 keyed to theshaft 56. Of course any other form ofV power-transmitting mechanism may be substituted for that shown so as to effect the driving of the shaft 44 from the main shaft 56. The stud shaft 6() is illustrated as having an enlarged portion 64 driven friction-tight into a socket in the frame until the end of the shaft engages a bent bracket-65 secured to the frame, this bracket serving to hold the idler gear 61 in place on the stud shaft. The shaft 56 is utilized to cause the operation of the other operative elements of the machine which areY power driven.
I have previously stated that the machine `is provided with what I have termed an inner tucking member, an outer tucking member which also serves in effecting the feed of the work, a presser-foot, and a `smoothing finger which operates on the feather of the work in advance of the cut- "'ters, I have referred tothe two tucking members as inner and outer, in View of the fact that one presses the fabric into what may be termed the inner channel of the innersole and the other'presses it into what may be termed the outer channel, that is the one nearest the outer edge of the innersole. The two tucking members are indicated respectively at 66, 67. That at 67 has the shape illustrated in Figures 3 and 4; that is to say, it is slightly recessed as at 68 at its lower end so that it ts down upon the rib 'on the work and forces the fabric down into the outer channel. Its extremity is serrated as at 69 in order that it may effectively engage the feather-of the inner-sole outside of the rib to effect the it'eeding thereof. It will be observed from l `igure '4 that, viewed in front elevation,
journaled on a stud secured to the head orlnain frame.` The upper end of therocking lever 7l fits upon a" bushing 76 locatedV on an eccentric 77 formed on or secured to the front end of the main driving shaft 56. Hence, when the said shaft is rotated, the lever 71 is rocked about the pivot stud 75 and is also moved upand down, whereby a four-way motion is impartedto the com` bined tucking and feeding member 67. That is, the feeding member is first dcpressed into engagement with the work and 'is then moved to the left in Figure 4 to advance the work one step, after which it is then moved vertically outof engagement with the work and to the right so that it may be again depressed into engagement with the work. c
The inner tucking member 66 has its operative end located opposite the operative end of the feeding member 67 so that the rib on the innersole may be passed between them. "lhistucking member 66 consists of a finger having the `conformation best shown in Figures 7 and 8. That is to say', it is provided withA afshank 78 by which it may be secured to its support, and a curved body portion terminating in a curved extremity 79 of a shape adaptedto force the fabric into the inner channel and under the undercut face of the rib as indicated in Figure 18. Viewed from the front of the machine, the finger 66 vis curved vlaterally to bring its operative end directly to confront the operative end ofthe feeding member. The shank 78 of the'member 66 is secured adjustably by a screw 8O tov a short lever 81 which is pivoted midwaybetween its ends upon a screw pin 82, passed through ears or lugs 88 on a block 84. This block 84 is likewise pivoted on a pin or stud secured in the lower end of ay carrier consisting ofa rocking lever 86. This lever 86, as shown in Figure 5, has a longitudinal slot 87 in which is located an angular block 88 on a stud 89 which is adjustable ink vertical lines by means to be explained. The upper end of tlielever 86 is aperturcd or recessed Vto tit on a bushing 90 located on the eccentric 77 formed on the driving shaft 56, so that, as the shaft is rotated, the lever 86 is moved up and down and is also swung about the axis of the stud 89. The short lever 81 is adapted to rock about the axis of thescrew pin 82, and` since the extren'rity of the finger 66 is located on one side of the axis of said screw pin, it willfbe observed that, as soon as the extremity of the tucking .linger enthel surface of the fabric on the innersole during the descent of the rocking lever 8,6, the linger will be caused to slide across the face of the fabric and into the reentrant angle formed by the rib and the surfacey of The short lever Slis heldV and the other'end of which is attached to a piu Q'lpiojecting laterally fioiii the lower end of the rocking lever 8.6L' The extent to which 'the shortlever Slinay swing about its pivot is liniited by an inclined face `SH on the block Se. The block 84 is capable of a liinited movement longitudinally of the rocking'lever For this purpose, it will be observed that it is provided with a slot (see Figure B). A spring normally holds the blockS downwardly. Itinay, with convenience, be .in the forni indicated at 96;
.l integrally with the linger 616 so as to consti.-
tute an extension of the shank thereof. It is desirable, however, to perniit of an adjusti'nent ofthe linger 66 in `reference to the screw pin 82, and, for this reason, it is forinedseparately froiii the short lever S1 and adjustably secured thereto. The detachaliility of the linger iroin the short shaft enables ine to substitute i'ingers pan ticulaily designed for the character .of the innersole being tucked and triii'niied. It is also desirablethat the finger should be capable of yielding bodily in reference to the rocking lever by which it is actuated so that it niay be used with innersoles 'of different A thickness.

I have referred to the fact that the rocking lever 86 is inounted upon a stud S0, and y 'that the latter is vertically adjustable. (lrdinarily the stud S0 is axially `alined withr the stud for the rocking lever T1 which carries the vcombined feeding and tueking finger or ineniber 07. Then vthe parts are located in this position, the extent offeeding inoveinent ofthe two tingersi, G7, is the saine, and the parts are therefore ordinarily `maintained. in this relation when the, Vfingers are engaged with the rib along theL sides of the innersole. Then the endA of the innersole,however, is to be tucked, particularly when the innersole is of a pointed shape, it is desirablethat the feeding inovein-ent of the linger G6 should be inuch shorter than the feeding nioveinent ofthe linger t5?. For this reason, the stu(v is secured to a slide 96 inovable in a 'vertical guideway fornicd in the niain fraine or head at 0'?. 'llo this slide is pivoted a link 98 hai-*ing its upper end pivoted to an arni 99 secured to y-aroelesliaft 100. lThis rock-shaft extends freni front to rear of the Vinachine, and on its rear end it has an arin 101-which is conf i nected by a ehainor other connection y102 tuck-ing members. `feijrfred to comprises a rod or bar 120 adjustably.secured` to the carriage 39. Itprojeets with afoot treadle, not sliowii,. but so arthan the feeding inovenient of theA finger 6,?.
The link 98 inay be engaged with the reduced forwardly-.projecting end of the stud and held in place thereon by a nutv103 and washer 104..,A spring 105 is secured to the arin 99 and toa pin106 on the fraine so as nori'nally toA draw the arni 99 up wardly until the'aiiis` of the stud 89 is in line with the axis of the stud 75 on which the rocking lever, 711 ,is fulcrunied.
- In cooperationV with the two tucking and `feeding nieinbers or fingersfG, 67, I einploy a presser-foot which is operated inv alternation therewith so that it is lifted froni the work when the feeding fingers are engaged with and nioving the work, and whichy is depressed intof 4engagement with the work whensaid lingers are disengaged therefrom.
Thispresserffoot isindicated at 107 and is located just in A.front of the cutters, as shown in Figure 1. Itis forinedfzand located to engage ythe feather' edge of the innersole, and it is secured shown in `Figure 1) to a tieally-adjustable bar or l carrier 108 inounted in guideways on the left side ofthe inachine viewed frein the"1:`.ront. To this bar or carrier there is securedy by pin 110 one kend of y,a spring 100, and the upper end of the springis secured to a pin 111 projecting `laterally froinvthe head. rIhe upper end of the carrier 108 is recessed or slotted at 112 to receive vtlieend of. a rocking lever 113 which/is fulcruined upona stud 114. The other end of the -roclginglever is connected by a pintle1115 with a link 1,16 pivoted by a pin or stud 11to `the `rocking=lever 71 at a pointadjacent the eccentric `T7,a.s best shown in Figure @The rocking lever 71 has an iiiternahrecess in which 4the link 116 is lo- `cated andintov which the end of the rocker 113 entends. The'ou'ter end. of the rocker 113 is engaged withr anadjustable abutment ,screw 118 extending .into the end of the n foregoing description (taken in connection with Figure 4t) that`as the rocking lever or carrier for `the pin (t7 is depressed, the carrier 108 is raised. and viceversa.
j Iiraddition to the ,foregoing elements or instruinentalities I providea nieniber which is adapted to rest upon and smooth down the fabric upon the rib and feather of the innersole in advance 4of the cutters andthe The instrumentality reinto an ear or lug 121 formed on said carrier and is held in place by a set screw 122. The forward end of said bar orf rod projects downwardly and laterally, Vas shown in Figur-e 7, and its operative. end portion L123) is so shaped as to bear against the outside of the rib and against the feather .so.that, as the work is fed therebcneath, the fabric is smoothed andpressed downward into engagement with the rib andthe feather; that is to say, it has a concave face 124 corre spending to the curved face of the rib and a flat face 125 lo rest upon the feather. The concave face doesnot always engage the fabric on the rib for the reason that the smoothing member is supported by the carriage for the cutting knives; and consequently at certain times, if the rib is located at variable distances from the edge of the feather, the smoothing member may sepa` rate from the rib, as for,` instance at the shank portion of the inner solewliere the rib is further from the feather than in the forepart of the innersole. y .I
Assuming that the innersole (t has been chaniielled and the lips turned to provide a rib and 'that the blank of frictioned fabric' c (or a fabric coated with some other suitable adhesive) has been placedupon the face of the innersole and pressed thereagainst sufficiently so that it sticks in place, the main work support is now depressed so that the iniiersole may be placed thereon with the end of the rib'at the inner side of the shank .in line with the lspace between the` two tucking and feeding fingers. Y The treadleis released andthe main work support moves upwardly and presses the innersole against the member 120. -The machine is started in operation, whereupon the presser-foot and the tucking fingers are moved alternately into and out of engagement with the work, the work being fed intermittently by the finger or member 67 and the finger' or member 66. The fabric laying and smoothing member 120 presses the fabric down upon the feather, and the two fingers 66, 67 force the fabric info the two channels or reentrant angles on both sides of the rib. The outer tucking member presses the fabric against the outer face of the rib and tends to crowd the rib bodily inwardly. At the same time, the lateral sliding movement of the end of the fin-` ger 66 has the effect of smoothing the fabric laterally into tlieinner channel and against the inner face of the rib. In fact, since the end of the finger 66 `moves toward andfrom the end ofthe finger 67, at the base of the rib, the tendency is to crowd the crown'of the rib inwardly or laterally over the end of finger 66, as shownv in Figure 13, so that an acute angle needle-receiving groove or channel is formed in the innersole. As the iunersole is fed along, the disk cutters sevei1 the fabric along a Vline just inside the edge of the feather, the cutter carriage being moved against the tension of vits spring by the engagement of the edge of the feather.
inenfl al table, the edge gage, andthe smooth-' ing linger) toward (the work table and its housing may be limited byY an abut-ment screw 127, passed through a block 128 snp-k ported by the frame, and arranged to engage said carriage, as shown in Figure 3. Thus the carriage may be stopped or limited in its forward movement so that the face of the trimming disk f8 will engage or lic close tothe inclined face of the housing of the work table.
