Toall whom it may concern:

Be it known that I, ALBIN VVAETH, of Stapleton, in the county of Richmond and State of New York, have invented anew and useful Improvement in Machines for Cutting Textile and other Materials; and I do hereby declare the following to be a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same, reference being had to the accompanying-drawing formingpart of thisspecification, in which drawing- Figural represents a sectional front view of my invention; Fig.2 isa transverse section of the same; Fig. 2*,is a side view of the cuttor-bar with the cutter and cleaner; operating in the knife-receiving socket; Fig. 3 is an invertedsectional plan of the same,'the line now,

This invention relates to a machine intended for cuttin g'cloth, muslin, paper, leather, or other materials used in the manufacture of garments or shoes, said machine being principally con structed of knife or cutter which works in a knife-receiving socket, one or both edges of whichform cutting-edges, the knife being sit-.

uated above the material to be out, while the knife-receivin g socket is situated beneath said material, and forms the support, or part of the support, of the same, the knife and socket being connected to a common rod or shaft in such. a manner that when the knife is turned the socket will follow, and that by the co-operation of the cutting-edges of the knife and of the socket the operation of cutting patterns of straight, curved, or'irregular lines, is eil'ected with ease and facility. The knife or cutting-blade is-secured to an arm extending at right angles from the driving sleeve or rod, the connection being made in such a 'manner that the said knife-carrying arm can be swiveled round the driving-shaft without being thrown out of gear with the same. With the knife and the knife-receiving socket, and the parts connecting the same, is combined an automatic-feed mechanism in such a manner that when the knife and socket are turned to follow the sinuosities of the pattern the feed mechanism partakes of this motion, and the knife can be readily made to follow a rectilinear or curved path. \Vith the feed mechanism is combined a presserffoot, which slides on the rod that carries the knife, andlis provided with a stop-lever, by means of which it can be locked in an elevated position. The knife is stamped out of sheet metal with a double cuttiugedge, and with a lockin g-sprin g formed at its rear edge, so that, Wili'fl said 'knife is passed through the mortise in the rod intended to receive the same, the lockingspring catches over the rear edge of said rod and retains the knife. The entire cutting mechanism is supported by a platform or head, which can be swiveled round in either direction by means of a hand or foot lover, or by a circular rack and pinion, which can be operated from a distance. From the parts which form the connection between the knife and the kniie-receiving'socket extends a handle, the support of which follows the knife, so that the position of the knife and the knifere ceiving socket can be accommodated to the formation of the pattern independent of the size or extent of the material from which the which form the connections between the knifereceivin'g socket and the knife arecombined two spreading-fingers, one on each side of the knife, to prevent the material, after the same has been cut out, from crowding the knife. With the knife and the knife-receiving socket is combined a" clearing-blade for the purpose of keeping the socket clear from fibers and other impurities. q

In the example represented by the drawing, the letter A designates a table, made of wood or other suitable material, and of I any desirable form or size. On this table is placed a circular platform or head, B, from the bottom surface of which extends a hanger, O, carrying a rod, D, thatis stepped in abearing, a, secured to a rod, 1), which is fastened between the legs of the table A. The rod D is firmly secured to the hanger C, and on its lower part is direction by the action of his foot, thepla-tform .two flanges, cc, which straddle the end-of a' carrying barF on being swivelcd round doscillates it imparts to the, sleeve E and bar F eccentric g revolves on the rod d, motion being foot and in the other direction by depressing formed a spring-catch, 'i, so that, when the 'shank of the knifeis pushed through the mordouble cuttin g-edge, either of which is brought knife. The material to be cut, on being fed and as the knifedescends the material is cut socket works the clearer I, which is firmly sefrom below, (see Fig. 2*.)

The knife G is stamped out of sheet metal, in the form shown-in Fig. 6. It presents a double cutting-edge, and on its" back is tise in the bar F said spring will cateh=over the rear edge'of the bar and retain theknife firmly in position. As the knife descends it enters a socket, H, which is firmly secured to the hanger (J, and the top of which presents a in operation according to the position of the under the knife, rests upon the top of the socket,

The action of the clearer is improved by malt-- This feed-dog straddles the'knife-supportported by a' lever, j, (Fig. 1,) which is pivoted atone end tothc hanger C, while its loose .end bears upon the cam-shaped end k of a hell-v This bell-crank lever has its fulcrum on it pivot, m, secured in a bracket vided with a slot, 0, which straddles a pin. 11, secured in the bar F. In the end of the arm't is secured a friction-roller, q, that bears against -the edge of a lever, 1', said lever being pressed up against the friction-roller by a spring, 8, (see Fig. 1.) The upper end of the lever r supports the hook-shaped tail-end of the feed-dog J, and said lever is curved, so that vwhen the friction-roller rises it imparts to the lever r an oscillating motion, andt-hereby the feed-dog is .carried forward toward the knife G; but before t giis forward motionof the feed-dogtakes place it v -'p'arte angeccentric. g,orlcy any other-shits;

v ake hold of the material to be cut and be iupositiourto carry said material-along when the forward motion of the feeddog takes. place. Aspring, t, (see Fig. 4,) which acts on the feed-dog, serves the double purpose of keeping the serrated end of the same down upon the lever j, and of pressing the h o0k-' shaped end of said feed-dog up against the lever r. When 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 carrying the material under the knife, and when the bar F descends the feed-dog is caused to drop, and then torecede ready for a new move. Thebar F'extends a certain distance beyond the mortise intended to receive the knife, and the upper end of said bar forms. the guide for the tubular shank of theipress er-foot K. This presser L foot straddles the knife, and -it -is*depressed--bytwo springs, u u, one on each side, so as to produce a uniformaction. These springs are hitched at their bottom ends to a wire'ipassin g through or fastened in the bar F, and their upper ends catch over the top edge of the tubular shank of the presser-foot. By the action of the presser-foot the material to he cut is kept down uponthe platform during the time the cutting takes place, and at the moment the feed motion takes place the presser-foot is raised sufficiently to allow the material to be fed with out obstruction. The press'er-foot can be raised by means of a handle, n, which is hinged to its shank, and which also acts as a stop to retain the foot in its elevated positiom For this purpose it is brought to bear upon the ed gs of a handle, to. the support of which rises from the platform or head B just behind the knife-supporting bar, said handle serving toturn the knife togetherwitli the knife-receivlug socket in eithen direction 'as thepattern to be cut may demand: "ttiie'supporttr'tn' handle w is thickerfthanthe knife-supporting bar,'and as said support followsth'eknife into.

the cut the material already cut is spread by said supportand prevented from crowding against the sides ofthe knife-supporting bar or of the knife.

It will be readily'seen that, in order toolitain a handle above the material to be cut, the support of said handle must extend up through the cut opened by the knife in the material, 7

and by "placing the handle in this position in QEri'se, so'that the ,teeth of said feed-dog relotiou toithe knife the workman is enabled to guide tne-knife w-itheaseand facility, and at the sametimethe great advan-ta go is gained that, by the support of the handle itself, the v material already cut is prevented from crowdingthe knife or the knife-suppo ing bar. as above stated.

From the head'B rise two v mold-boaml-like flanges, a, one oneach side of, the knife-supportingbar F, and close to the same. These vflanges serve also to prevent. the cute-material iriom crowding'ag'ainst the knife or the knife- 'inner end a pinion, d, and at its outer end a handle, f. f

d is thrown in gear with the rack b, and the By pushing in this rod the pinion head B can be rotated by turning the handle j. This mechanism may be substituted for the handle w,- but in practice I prefer to use the handle w secured to a support which rises from the head B. y

The material to be cut is adjusted on the head B under the presserfoot, and by impartin gto the knife the required motion the operation of cutting is effected.

1f the knife is to follow a curved path and the piece to be cut is small thehead may remain stationary, and the material can be turned, as required; but if the piece from which a certain pattern is to be. cut. out is large, and cannot be conveniently turned, then I turn the head B, causing the knife to follow the outlines of the pattern previously marked on the material a'nd in turning the knife the knife-receiving-sbcket is also turned, so that those parts always preserve their relative position toward each other.

This is a very essential feature of my ma.- chiue, for, if the knife and the knife-receiving socket were not so connected, the operation of cutting out, irregular patterns from large pieces of material by the aid of this machine would be exceedingly difficult, if not entirely impossible. In order to accomplish this result, it is essential that thestandard to which the handle w isattached is so situated that the same passes through the cut opened by the knife. If this standard does not pass through thecut opened by the knife, the materialicannot be freely moved under the knife in every direction, and the. machine can only: be used, for cutting l out-patterns from come-.-

paratively small pieces of clothor other ma terial, but by placingsaid standard in such a-position that it passes through thecut opened bytheknife, I am enabled to cut out patterns from pieces of cloth or other material of any desired size, and for this reason my machine is particularly valuable for large clothing-houses, where the patterns are drawn in succession on whole pieces of cloth or other material and then cut out. by carrying said pieces through under my cutting mechanism.

My machine is principally intended for large clothing manufacturers, and it is capable of cutting at one operation through twenty or more thicknesses of cloth or other textile fab rics, or through a large number of thicknesses of paper, and also through several thicknesses of leather.

The manipulation of the machine is quitesimple, and its operation is exceedi-n glyirapid,

so that it produces .a great saving in hand. a

It must be remarked that, for dili'erenthirtdsg of work the knife. may be changed; it mayg for instance, be made to act as a punch-woe buttonhole cutter, or as a cutter of any other description, but in all cases, whate er the form or construction of the knife may be,'the knife-receivin g socketinust be connected with the knife so that these two parts will preserve their relative position toward each 1 other in whatever direction the kuifemay be turned. What I claim as new, and desireto secure by LettersPa-tent, is-
