Letter-S'Patent No. 106,101, lated August 2, 18,70.

The Schedule referred to in these Letters r'atent and making part of the s'ame Be it known that I, ALBIN WARTH, of Stapleton, in the county of Richmond; and State of N ew York, have invented a new and improved Machine for Gutting Textile and other Materials; Vand I do hereby dcclare the following to be a full, clear, `and exact description thereof', which will enable others skilled'in the'art to make and .had to the accompanying drawing forming part of thlsfspecrhcation, in which drawing- Figure 1 -leprcsents a sectional front view of the' invention.-

Figure 2 is a transverse'section of the same.v Figure 3 is an inverted sectional plan of the same, theuline x x, tig. 1, indicating'the plan of section.

lignre 4 is a similar viewV thereof, the plane .of section heilig indicatedI by the liiie y y, 1. `Figure 5 is` asectional plan or tp view thereof.

Figure 6 is a detached view of the/llasp. `Figure 7 is a detached plan and side elevation of the iced-dog.

'Similar letters indicate corresponding parts. Q'lhisinvention relates to a machine intendedffor cutting cloth, mnslin, paper, leather, or other mat-erials used in `the manufacture ot' garments or slices, said machine 'being principally constructed of a' reciprocat-ing knife `and automatic feed mechanism, in such ,amanner that the material to be cut is gradually fed under the knife, and that, byturniiig or guiding the material, the knifecan be made to follow a rectilinear .or curved path. Instead of turning the material to be cut, the knife and feed mechanism, together with the platform supporting said' material, may be made to swivel insuch a manuel-,that any desired pattern can e out out from a large piece of cloth or otherma-t-erial, without diirisult-y. y p (/f 1With the feed mechanism is combined presser-v oot, which slides on fhei'odthat carries theknife, and is provided with a stop-lever, gpl be locked in an elevated position.

'' The knife isstamped out of sheet-metal with a double cutting-edge, and with a locking-spring formed at its rear edge, so that, when said -knife is passed through t-he mort-isc in t-herod int-ended to receive the same, the locking-spring catches over 'the rear edge of .i

salidrod, and retains the knife.

The entire mechanism is supported` by a lplatform capable of heilig swiveled round in either direction, either by a hand-lever attached to its top surface, or

by footp'ower applied to a foot-,piece below, or by a f circular rack and pinion, aqdist-ance. '7i' The material, after having been cnt, is prevented from crowding the knife by means of spreading flanges rising from the plat-form ou either side ofsaid rod.

Theknife, ondescending, enters a socket with a which can be `operated from usethe same, reference being on its lower part is. mounted by means ofwhich it other suitable material, and of anvdesirahlel form or n this table is placed a circular platform, B, from the` bottom surface of which extends Va hanger, C, carrying a rod, D, that is stepped in a bearing, @,secured to a rod, b, which is fastened between the legs of the table A. l

l The rod D is firmly secured to' the hanger C, and a foot-piece, c, so that the operator can turn the hanger and the platfhrm in either direction by the actionef his foot, theplatforn'i B b cing titted into the table A, sothat itcan he readily swiveled round its own center. 4

,f'lhe rod D forms a 'guide for the sleeve E, from the top part of which extends a fiat bar, 1 ,'ntended to i carry the knife G, while on its bottom part are secured two a-nges, e c, which straddle the end of a lever, j, to which an oscillating'motion is imparted 'by an cccentric, g, or by any other suitable mechanism //As the lever f oscillatels, it imparts to the sleeve.

-E and bar F areciprocating yrising and falling motion.

fThe eccentric g revolves on the rod b, motion beilgiiupmteito`it by hand, foot, orany other powerf- 1 4f toot-power is used, I employ a treadle, h, which is hung ator near the center of its length, so that mot-ion can`be imparted tov it in one direct-ion by depressing the toes ofthe foot, and in the other direction by depressing the heel." A. i ./if'lhe knife G is stamped out of sheet-metal in theform shown in tig. (3. It presents a double cutting edge, and on its back edge is formeda spring catch, i, so that, when thc shank ofthe knife is pushed through its mortise" in the bar 11, said spring will catch over the rear edge of the bai-'and retain the knife'iirml y in position.

a/As the knifepdcscemls, it enters a socket, H, which is lirmly secured to the hanger C, and the top of which presents double cutting, edges, either of which is brought iiroperation accord-ing to the position of the knife. j.

-; The material to he cut, ou' being fed under the knife, rests upon ,the top of the socket, and, as the knife descends, the material is cnthy the action ot' the cutting-edge of the knife against the cutting-edge of the .f In the socket works the clearer I, which is firmly 'secured to the bar F, and passes into tbe socket from below,w(ee tig. 2.)

, By thvaction of ,this clearer', all fibel/s and small particles, which are liable to become disengaged from the material to be cut during the operation ofcutting, are pushed out of the socket, and thereby the socket is prevented from becoming choked. The action of the clearer is improved by making its edge serrated.

j. 'The material to he cut is fed to the knife by the action of a feed-dog, J, detached viewsof which are sl um i n 1i". 7. This feed-dog straddles the bar F, and its serrated front end is supported by a lever, j, fig. 1, which is pivoted at one end t-o the hanger ,0, while its loose t ,end bears upon the cam-shaped end It of c a bell-crank lever Irl.' f

is bell-crank lever has its fulcrmn on a pivot, m.,

parts to the lever lran oscillating motion,and therehy the feed-dog is carried forward toward the knife G;

but before this forward motion of the feed-dog takes piace, the camshaped end of the arm 7c of the' elbowlevel' causes the lever j, and with it the feed-dog J ,to-

rise, so that the teeth of said feed-dog will take hold of the material to be out, and he in position to carry said material along when the forward motion of th e feed-dog takes place. yA spring, t, (sec if". 4,)which acts on the. feed-dog, serves the double purpose of keeping theserrated end ofthe same down upon the lever j and of pressing the hook-shaped end-of saidfeed-dog nir-'against the lever -r.

\Vhen' the bar F rises, therefore, the feed-dog is first caused to take hold of the material, and then it receives the forward motion, thereby earryingthe material under the knife, and, when the bar F descends, the feed-dog is caused to drop and the-n to recede ready for a new move. A 'y The bar F extends a cert-aiu distance beyond the mortise intended to receive the knife, and t-he upper end of said bar forms the guide for the tubular shank ofthe pressewfootelgg llhis presser-foot straddles the knife, and it is depressed by the action of two springs, u u, one on each side, so as'to produce a uniform action. These springs are hitched at their bottom ends lo a wire passing through or fastened in the har F, and their upper ends catch over the top edge of the tubular shank of the n'esser-foot. sk y the action of the presser-foot, the material to be cut is kept down upon the platform during the time the cutting takes place, and at the moment the feedmotion takes place, the presser-foot is raised sutliciently to allow'the material to be .fed without obstruction. l

The presser-foot can he raised hy means of a handle, r, which is hinged to its shank, and which also acts asastop to retain the foot in its elevated position. \...-For this purpose it is brought to bear upon the edge of a handle, w, which rises from the platform B, and serves to turn the same, together with the entire cut-ting mechanism, in either direction, as the pattern Y to be eut may demand.

#Hirom the platform B rise two mokl-hoard-likc flanges, a', one on each side of the bar F, and close to the same, for the purpose of throwing ofi' the material after it has been cut, and preventing the same from crowding against the sides of thebar F.

--lhe platform is provided at'its under surface with a circular' rack, b', (see figs. 2, 3, and 4,) and through the edge of the table A extends a rod, c', which-carries at its inner end a pinion, d', and at its onterend a handle, f'.

,By pushing in this rod ,the pinion d is tln'own in gear with the rack b', and the platform B can he rotated by turning the handle f ./-'J.l1ematerial to be out is adjusted on the platform B under the presser-foot, and, byimparting to the cutter-bar a reciprocating motion, the operation of cutting is effe ed.

7If t' ie knife is to follow a curved path, and the piece to he eut is small, the platform may remain stationary, and the material can be turned as required;v but if the piece from which a certain pattern is to be cut outislaree anil cannot be convenienti turned then I turn the platform B', either by hand or hy foot, causing the knife to follow the outlines ofthe pattern, previously marked on the material.

{11E-his machine is principallyintended for large clothing manufacturers, and 4it. is capable of cutting at one operation through twenty or more thicknesses of cloth y or other textile fabrics, or through a still larger number of thicknesses of paper, or throughsevcral thicknesses of leather. The manipulation of the machine is quite simple, and its operation is exceedingly rapid, so that it produeesa great saving in hand-labor.

'--l It must he remarked that, for different kinds of work, the knife may be changed; it may, for instance,

be made to act as a punch or a button-hole cutter, or

as a cutter of any other description.

What I claim as new, and desire to secure by Let ters Patent, 'Ls- 1. The presser-foot, arranged to slide in the reciprocating shaft of the cutter, and provided with suitable tension-spring;` substantially as and for the purpose described.

2. The handle W, rising from the rotating platform B, in combination with the latch yv ofthe presser-foot, serving to operate the platform and hold the presserfoot when elevated, as and for the purpose described.

3. `The knife G, provided with a spring catch formed at its rear edge, substantially as -set forth.

4. The rotating platform B, carrying the feeding and cutting mechanism and their operating parts, substantially as and for the purpose described.-

, 5. The arrangement of a socket with a double eutting-edge, to -act in combination with the reciprocating knife, substantially as described.

6. Thearrangement of a clearing-blade, attached to the cutter-bar, and serving to clear the socket H, substantially as described.

7. 4The bell-crank lever It l and levers j and o', in combination with the cutter-bar F and feed-dog J, substantially as described.

8.; The stationary mold-board-shaped ianges a' a', embracing the sides of the reciprocating cutter-bar F, for throwing ofi the cut material and preventing clogging with the bar, as set forth.

This specification signed hy me this 8th day of April, 1870. t
