To aIZZwLomz'tma/y concern.- i i Be it known that I', ERAs'rU's E.'W1NKLEY, a citizen of the United States, residing at Lynn, in thecounty of Essexy and State 'of Massachusetts, have invented certain new and useful Improvements in vStock-Cutting Machines; and I do hereby declare the fol-- lowing to be a full, clear, Aand exact descrip'v tion of theA invention, such as Will enable l0 others skilled in the art to which it apper-vA tains to make and usethe same. A

:This invention. Arelates to stock-cutting f' machines in Which the stock is cut into pieces or blanks andthe pieces are delivered in stacked relation ready for transferral 4to* other machines.A More particularly, the invention relates to machines inlwhich articles: .l of tapering cross-sectional form, such as the n Wedge-lifts usedin the manufacture of shoe heels, are cut from strips of Asuitable sheet; Y material and are thenstacked facelto-face` With 'theirthick and thin'edges alternating,'=

1i iin. o-rcler that the liftsfmaywbe compactly stored, or conveniently-v handled, or acted upon bythe feed mechanisms ofotherma`4 chines.

A co-pending ent applicant, discloses. an automatic heel building machine `that is constructed and opf erated to build heels in which ,Wedge-liftsl v sequenceat successive assembling stations to produce yheels of anydesired form. Thel commercial success of a machineA ofthis lcharacter depends upon the'facility lWith which the lifts, and morev particularly` the Wedge-lifts, can be cutand stacked v,in-the', required relationship preparatory to being supplied to' the, magazines ofthe machine. One object of the present invention is to pro-vide a stock-,cutting machine `y of ini-- proved construction for producingfdinked.

or diedoutv articles andwdelivyeriiig them in stacked relation. f i n To' the accomplishment/of this object,`one

l application, i Serial 208,443, filed Decemberv 22, 1917, by tlie'pres-4 feature of the invention' comprises a 'ma' chine having'a die for cutting pieces of "sheetI material andmeans for removing the pieces from the die fas theyl are'cut' and assembling` them tion;

Another vobject ofthe invention is to prof.

vide, ina stock-cuttingl machine embodying the feature above specified, means whereby* pieces cut v'from y.sheet material of tapering crosssectional forinm'ay be 'assembled in al stack With their ,thickA and thin edges alternating. i i 1 Tothe lastzmentio'ned end another feature of ,the` invention resides in mechanism: for' turning-alternate piecesA ends-for-end afterl they have been cutyand-removed from'thel die.

Referring to the drawings; 'the machine comprises, 1n general, aframe 30 igs. 1,

3 and 4) for supporting 'the various com-v ponent elements embodied inthe machine; a

stationary removable die 32 (Figs. 3, 13 and- 1,4) which `is rmounted in the upper portion of the 'frame and is arranged with its cutting edge disposed in a vertical plane and directed rearwardly; a horizontally reciprocating rectangular cutting-block 34 for cooperating with the die to cut lifts from strips of stock introduced between the block and the die; a stationary feed platform 36 (Figs. 1 and 15) across which astrip which is to be operated upon is fed lengthwise to the die, the strip being supported in 'ay vertical plane with its thicker longitudinal edge resting on said platform; a pivotally mounted strip-supporting bar or plateform 38 (Figs. 16 and 17) located beneath the die and normally alined with the stationary feed platform 36 so as to support the leading end portion of the strip which is opposite the die, and which is displaced forwardly with said portion of the strip as the latter is forced against the die by each advance of the cutting-block and held in its forwardly displaced position, after the last cutting operation has been performed on each strip, to permit the escape of the waste-end of thestripI from the line of feed of a succeeding strip; a table or shelf 40 (Figs. 3, 4 and 15) at the top of the front of the machine, upon which a supply of strips are piled flatwise, one upon another, within easy reach of the operator; means disposed at the rear of the supply table 40 including a plurality of fingers 42 (see also Figs. 15, 17 and 18) for supporting one of said strips at a time as it is presented widthwisey and in a vertical plane to said means by the operator and adapted to be automatically retracted from strip-supporting position to drop the strip edgewise onto the feed platform `36; a main feed mechanism embodyingV a feed dog comprising a pair of gripper jaws 44 and 46 for closing upon op-' 'i posite sides of the stock and advancing it step-by-step to the cutting mechanism; an end-stop or gage 48 (Figs. 11, 14 'and 16) adjacent the farther side of the die against which the stock is fed and which serves to determine the `length of the feed movements; i

a die-stripper 5() (Figs. 3 and 11) a reciprocating and rotatable picker 52 (Figs. 13 and 14) for removing the lifts forwardly throughthe die and for turning alternate lifts 1800 so that the lifts may be stackediin straight column formation and in close contactr with each Aother throughout their width an ejector v54 which engages the rear side face n (Figs. 13, 2l and 22) for advancing the liftsk in stacked formation through the magazine 56; control mechanism including a feeler 60 (Figs. 14,16 and 19) located beneath the end-stop 48 for detecting Vthe presence :or absence of the stock and controllingthe actua-. tion of thelift-pickerc52 accordingly.; an y auxiliary feed device'` including a, pair of: pusher 'fingers 62 (see also Fig. 18)*which '.4 engage the vrear edge -of the strip of stock. to

.Referring vparticularly to Figs. 1,.3,4, 6

and 7, the frame 30, upon which the.com. ponent parts of themachine are mounted,

comprises a head 70; a substantially,rectanf.l

gular casing or frame 72 which supports the head 70 and encloses thecamsA and certain portions ofthe associated operative mecha- ?nism; a'basel 74 upon which the frame 72 rests, and a pedestal75 rising from the base 74,- which supports the strip-feedingmechanisms and to' which is secured abracket76 that supports the outer endof the supply -"table 40. The picker mechanism is enclosed andprotected byal small vrectangular casing r 77 (see-also F igs.f9 and 10) which is ysecured tothe top of the headf70, at the fronto'f the machine, and is Vprovided `with a-cover plate 78. A frame member 7 9 rises -fromthe ytop of the casing 72, on the right side: of the magazine 58, forthe purpose ofsupporting the inner end ofthe supplytable 40and pro# viding bearings for various partsf of vthe op! f Lerating mechanismj v i f I.' l l A main shaft80f'isjournaled in'bearings i 82 inthe head 70y and two cam shafts I84 and 86fare carried in suitable bearings'r in the cas ing or frame 72..I The main shaft 80 is pro- 50r -vided with a fast pulleyf88 and a loosepulley 90 with which a belt. 92 (Fig. 3) is adapted to cooperate. The belt-92may be shifted :from one' pulley tothe other by means of a belt-shifter 94 which is carried 55' at one end of a horizontal rod 96 that is mounted at the rear o-f the machine 'for longitudinalslidingmovement in bearings 98- on the frame 72. In order to preventtheA y belt-'shifter rod 96 from turning in its bear-l s0 f ings 98, the belt-shifter isfurther supported by meansof a pin4 100 which projectsfoutwardly from the frame7 2 through a'bearingf lug 102 which extends forwardly fromr the belvt-shifter- The belt-shifter rod 96 is operey 3 G5 atively connected by alink 104 with ai rocker arm; 106 .which is fixed Ona rock shaft.10 8 that extends' forwardlytat'right angles on.-4 the rod96 and is adapted toturnfinbearingbrackets 110ontl1'eside of the frame 172;A The front end-of the lshaft 108 is: providedA with an operating crank 1112'.
