Be it known that FRED L. MARK, deceased,4

y a citizen of the United States,` formerly 17e-i` siding at Chicago, County of Cook, andS'tate of llinoisrhas invented a eertain nexv and useful `Improvenient in Cutting lilachnes,`

of Whioli the following is a specification".

This lnventlon relates to, cutting niaehinesinfgeneral2 lout `more Apartieularly to machines for cutting cloth Tor. othersheet-` i material, y and more especially to machinery for euttinggdiscs or` othersrnall sectionsof cloth fromv the sheet "-W'hile the latter' is maintained in flat and stretched condition; and `preferably with one `sheet supeirposed uponanother, so that afplurality offlayers can becut at the saine time.

`Generally statc,d,` therefore, the object of the invention `is to provide. a novel andimproved construetion `whereby cloth orl other sheet materia-l canV lbe eut or subdivided intofdiscs or other `small sections, inja eon` venientand economical manne-Anth as little"waste as possible, and whereby a plural-` ity .oyf i layers of cloth Vo-r other sheet material can be out at the "same time',` for anyA desired purpose` butmore. particularly for `the `pur-` pose" of cutting out sinill'y discs of cloth Wliichcan be used inthemanufactnre of powder puffs" or other similar.V articles," as will hereinafter more jfully appear. l

It is also an ob]`eet to provide certain de@ l tailsand" features of construction and com-` binations tending toi inerease the general eiiieienoy andthe desirability of @a cutting machine of this p artieular charaeter To the foregoing "and other useful ends the invention c-"onsistsin` matters hereinafter set forth and claimed and shownin the ac-` companying drawings in Which-e Figurel aplan of a` cutting machine enibodying the principles ofthe invention,I with certain `intermediate portions thereof shown broken away for convenience of illustration.

Asthus illustrated, the invention co1nprises fa tabledile strueturehaving a rigid frame 1 supported at a suitable height by the legs 2v Which restsI on the floor. ri`he side portions 3 are inthe nature ofbraelrets and are adjustable up and down on said Vframe by reasonof the slots and nuts fr provided `thereon, and .the upper ends of these brackets have notches 5 along their upper edges. A swinging support G isprovided With a rigid transverse member 7 havingpins or trunnions 8 adapted to eng-age the notches `5, `whereby said support 6 is adapted to swing up vand down about a transverse axis.` The ringlilreor `'annular inember) has teelt-l1v 10"for engagingV the cloth, as Will hereinafter more fully appear, and is mounted upon a. supple mental sWinging support 11 which is pivoted upon the under side` of said other support at 12, and which is normally locked inr-aised position bya small latch or eatchl?) of `any suitable elianar/ter;A This ring-like member 9 isipro-vided with al handlell byl \\"i` ;h-` it may be raised and lowered. The rotary and cylindricalcutter 15 is carried on the lower end of a spindle or shaft l-carried by Y the bearings-17'provided on the front end i of the support 6, Wherebythis cutter is adaptedto extend thro-ugh and rotate Withinthe ring-like member 9 previously de scribed. A motor 1S is mounted on the rear end `of `the support S to operate said cut ter,` and for this purpose the. upper en d of said shaft is provided with a pulley wheel 19 connected by a belt 20 to said motor.` The motor over balances the cutter, so that the latter is normally in `raised position, and to limit this upward movement of the cutter theswinging support@` has a portion 2l to engage `the stationary stop 22 swivelli' mounted on the body frame ofthemashine Any suitable means can be employed for supplying electric current to said motor. A handle 23 1s secured to the outer end of the head 24 of the swinging support 6, and with this arrange-ment the supports 6 and 11 can be swung up and down together or separately.

The means for holding the cloth are as follows: The side portions of the main body frame are provided with parallel and longitudinally extending guides 25 which are carried by adjusting screw devices 26, of any suitable character` whereby these guides can be moved toward and away from each other for different widths of cloth. The cloth holding frame 27 is slidable back and forth on these guides, and is provided with metal portions 28 to receive the cloth clamping bars 29 which have teeth 30 to pierce and hold the cloth. The metal strips 31 are mounted on top of the cloth holding frame 27, and are provided with teeth 32 for enga-ging the cloth. It will be seen that the various layers of cloth 33 are clamped between the bars 29, and it will be seen that the metal clamping jaws 33 are applied to the upper edges of the cloth holding frame and held in place by bolts to compress the superposed layers of clot-h and bars 29 to tightly hold the cloth horizontal in stretched condition. The cloth is not held at the front end of the machine, but at the rear end of the clot-h holding frame 27 there are metal holding devices 35, and the bars 36 have metal portions 37 to engage the metal elements 35, in the manner shown in the drawings, so that the bars 36 are held one above the other transversely of the machine. Teeth 38 are provided on the bars 36, to pierce and hold the cloth, and a metal strip 39 is secured to the lower edge of the cloth frame and provided with teeth 40 to engage the cloth. Thumb buttons 4l are provided on the cloth frame to hold the bars 3G down, so that the cloth will be maintained in stretched condition. This frame 27 upon which the cloth is thus mounted and held horizontally is adapted to slide longitudirally of the machine, and is for this purpose provided with an internally threaded sleeve 42 which travels like a nut on the threaded rod 43, which latter extends longitudinally of the machine, below the cloth, and is supported by bearings 44 at the front and rear ends of the stationary body frame of the machine. Said threaded rod 43 is provided at its front end with a handle or crank 45 for rotation of the rod to move the cloth frame and the cloth back and forth longitudinally of the machine whenever such is necessary or desirable.

Now the operator sits in the space 46 at the front end of the machine, where the three handles 14, 23 and 45 are` easily reached, and where the cloth extends over the stationary bed or cutting table 47 carried by the stationary body frame. It will also be seen that the pivoted or swinging support 6 is provided with a vertical swivel 48 whereby the cutter 15 and its toothed holding ring 9 may be swung from side to side, in the manner shown in dotted lines in Figure 1, whereby it is possible to place said cutter and holding ring on any portion of the clot-h. The operator lirst unlatclies the support 11, and lowers the latter by the handle 14 until the teeth 10 engage the section of the cloth to be cut. Then the operator pulls down on the handle or manual-actuator 23 to lower the cutter into engagement with the section of cloth thus held by the teeth 10, and downward pressure forces the cutter through the different layers of the cloth and into engagement with the table 47, thus cutting out several discs of cloth. It will be understood that the shaft 16, and also the swivel 48, are approximately vertical when the cutter is thus lowered into operative position. The table 47 is preferably of some material which will not dull the edge of the cutter. The cutter is rotated at high speed, by the motor 18, during this cutting operation. The operator then releases the handle 23, allowing the cutter to rise, and then shifts the holding ring 9 on to a different spot on the cloth. and the cutting operation is then repeated. Cutters of different sizes can be employed for making large or small discs of cloth, as may be desired. Adjustment of the trunnions 8 from one notch 5 to another is possible if such is necessary or desirable. Also, as stated, the cut-ting action can be regulated to ensure the desired result by vertical adjustment of the brackets 3 previously mentioned. With this arrangement the operator can cut discs from the cloth, with as little waste as possible, and with ease and convenience and with very little expense for power to drive the cutter. Then the cloth is all reduced to discs, by the repeated operation of the cutter, the cutting means are then raised and latched in raised position as shown in Figure 2, and the residue of the cloth is removed from the cloth frame and fresh sheets o; layers of cloth are inserted.

It will be seen that a cutting machine of this kind can be used for any suitable or desired purpose. For example, it can be used for cutting cloth in the manner shown and described, in the manufacture of' powder puffs, the discs of cloth being sewed or fastened together to produce the desired article or product of manufacture. The. cutting means are power driven, but are manually controllable and adapted to be manipulated at will by the manual actuator 23 to place the annular cutting edge exactly where wanted on the cloth. Thus the cutter is moved about from one place to another by memset thefsame' power `by which it is l lonessed Shifting ofcloth `is also manually contr" led,

sothat fast as the olothiscut intjofdiscs, by swinging the cutter transversely, the cloth as al whole cen be pulledyforward to bring fresh sections thereof within `the `operative range of thecutter.

` In the lateral adjustnient of the two sides of the fra-me 27,l by "adjusting the guides 25,

previously "described, it will be seenthat some `provisions are necessary for' the trans-V verse rear end of the cloth holding traine, in order to permit of this adjustment, shown, therefore, the rear end portion` off the cloth holding frame is providedwith L-shaped brackets llfhaving slots 49,2t11dthe transverse` rear portion 50 'of l the `frame issupported'b'y bolts l'which are slidble in these slots. In this way, therefore, the rear end portion 50 of the frame is normally rigid with the sides thereof, but `may `be loosenedby turning the nuts of thebolts 5l when it is desired to adjust the two sides of the frame toivardor away from each otlier,

It will be seen that the mounting #of the motor 8` on theV sup/port 6 simplifies the problem of Vdriving thelcutter, as `noconilplifv cztted driving arrangement is required such es might be `necessary if the niotorufere mounted on the body frame of the machine,

i With the 'ungement shown, the motor und the cutter are' mounted on the saine lni(')ifalole supp t, and the `motoris' moved around by the slitting' of the cutter. Furthermore, itlwillfbe seenthat the cutter hasa limited range ot op eration, of course, and that for this reason the clo-th is supported `by means for'- presenting successiveV sections oi fthe cloth `to thecutter, or for causing successive `sections of the cloth to be broughtl within the range otoperation of thecutter. Therefore, the

cloth is shifted andthen heldstationary un+ `til theysection thereofthus broughtwithin the range of operation of "the cutter is eX- hausted or reduced lto discs out tlierefrom, and then the cloth iswshifted agtin,w from "time totime, until the entire"lengththereof hes been operated uponin, the desiredimny ..,at.
