To vall whom it may concern:

Be it known that I, ALBIN WARTH, a citi- 'zen of the United States, residing at Stapleton, in the county of Richmond, State of New York, have invented new and useful Improvements in Machines for Cutting Textile and other Materials, of which the following is a specification.

' This invention relates to a machine intended for cutting cloth, muslin, paper, leather, or other Inaterials used' in the manufacture of The machines in use previous to this inven tion for cutting such materials were operated almost exclusively by hand, applied to a handle connected directly with the blade or cutting-instrument, so that one cut was made for every movement of the handle, and consequently the number of cuts made in a given time was limited bythe number ofv movements that could be made by the hand of the operator within the said time, while the only force that could be applied tothe cutting-instrument was that developed by the hand of the operator. A machine had been devised to out the material in sheets by power by means of a revolving circular knife or cutter; but in this case the cutter could not be turned or swiveled to make the direction of its cuttingedge correspond withthe direction of the line to be cut; hence the machine was not adapted to general use. Another machine had been devised to cut such materialshy means of a reciprocating knife operated by power, said knife being tted to be turned laterally or swiveled while it was reciprocated; but the machine`(so far as 1 can ascertain) liever came into general use for the lack, among other things, (in my opinion,) of a direct connection between the knife and the movable cloth-support which held the material for the action of the knife.

The object of the invention which constitutes the subject of this patent is to enable textile and other materials, in iiat sheets, to be cut according to any desired pattern or desi gn with speed and by other power than the human hand, so that the cutting device or knife may be driven with a greatly higher speed than is attainable when the number of cuts device which carries the knife-body and the knife or cutter in an upright position above the cloth; a laterally turning or swiveling cloth-support which is `capable of being swiveled or turned laterally relatively to the table, and which supports a portion of the material near the knife or cutter, and sustains the particular part of the material on which the cutting-edge is operating close to the plane of motion of said edge, so Vas to prevent it from escaping from the action of said edge, the swiveling characteristic of this cloth-support permitting it and the bar which holds the knife and the knife,both of which are maintained in an upright position byit or by a part of it, to be swiveled or turned laterally, so as to vaccommodate the direction of the cuttingedge to the direction in which the cut is to beA made; a movable knife or cutting-instrument whose edge has a cutting motion relatively to the platform and to the swiveling cloth-support, for the purpose of cutting the material; an upright bar which projects upward from the platform and swiveling cloth-support, and combines the knife with them, so that whenever the platform and cloth-support are swiveled the knife is compelled to swivel correspondingly. As the swiveling platform and cloth-support are always below the material to be cut while the body of the knife is above the material, this upright bar is, of necessity, arranged close to the knife, ortn its'vicinity, and so'that it will pass edgewise through thecut or slit cut in the material bythe action of the cuttingedge. The said bar also holds the knife with the plane of its body upright or at right angles, or thereabout, to the surface of the table by which the material to be cut is supported, and

IOO

to the surface of the platform and `swiveling cloth-support when the cutting-edge severs the material. A driving-pulley which may be caused to revolve at a high speed by means other than the human hand, and which, while revolving, is stationary or has afixed relationship to thc table, through which pulley the power employed is transmitted to the knife, so that by reason of the high speed of said pulley the knife-ed ge may be driven or caused to move with a high speed; a handle secured to the swiveling platform and cloth-support, and located above the position ofthe material to be cut, the said handle enabling the operator to apply one hand over the material, so as to turn the cloth-support and knife laterally or swivel them, as required, according to the direction in which the cut is to be made; a clearer for removing bers `and particles from the track of the knife-edge; a feed-dog for moving the material; a presser-foot for holding down the materia-l, and lateral projections upon the clothsupport for throwngotf the material or spreading its edges after it is cut.

The various combinations of the above and other devices which constitute my invention are pointed out in the claims at the close of this specification.

In order that these combinations may be fully understood, I have represented the same in the accompanying drawings, in which- Figure 1 represents a sectional front view of the invention. Fig. 2 is a transverse section ofthe same. Fig. 2* is a sectional side view of the cutter, the support for the material to he cut, and the clearer. Fig. 3 is an inverted sectional plan of the same, the line Fig. 1, indicatingtthe plane of` section. Fig. 4 is a similar view thereof, the plane of section being indicated by the line yy, Fig. 1. Fig. 5 is a sectional planor top view thereof. Fig. 6 is a detached view of the knife. Fig. 7 is a detached plan and side elevation of the feed-dog. Fig. S is a representation of a serrated knife.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a table, made of wood or other suitable material and of any desirable form or size, its upper surface being horizontal, so as to support the material to be cut. On this table is placed a circular platform, B, which is capable of being swiveled round in either direction. To

this platform is secured the socket H, the

edges of whose upper surface are close to the plane of motion of the knife G. The upper surfaces ofthe platform B and socket H jointly constitute, in this machine, the swiveliu g clothsupport by which the part of the cloth in the vicinity ofthe knife and upon which the cutting-edge is operating is sustained or held.

from escaping from its action.

From the bottom surface of the platform B extends a hanger, C, carrying arod, D, that is stepped in a bearing, a, secured to a rod, b, which is fastened between the legs of the table A. The rod D is firmly secured to the han ger C, and on its lower part is mounted a foot-piece, c, so that the operator can turn the hanger and the platform with the socket in either direction by the action of his foot, the platform B being litted into the table A,s`o that it can be readily swiveled found its own center. rlhe rod D forms a guide for the sleeve E, from the top part of which extends upward a flat har, F, intended to carry the knife G. This b'ar is connected laterally with the platform by means ofthe bracket-piece c', so that the first two are compelled to swivel simultaneously, andthe 'bar F is maintained in an uprightl position relatively to the cloth-snp-. port and table. -As the platform B forms part ot' the swiveling cloth-support B H, this support and the knife which the bar carries are combined by said upright bar F, so that in whatever direction the swiveling cloth-support is-turned laterally or swiveled the knife is compelled to turu in the same direction, whereby its edge is maintained always in the line of the cut to be made. As this upright bar combines the body of the knife above the position of the material to be out with the swiveling platform and swiveling cloth-support beneath that position, said bar is necessarily close to the knife, or in its vicinity, and it is also edgewise to the line ot' cut, so that it will pass readily'7 between the edges of the cut made by the knife-edge. As the bar F, which holds the knife, is itself held steady in an upright position relatively to the table by the platform and the swivelin g cloth-support, the said swiveling platform and the swiveling clothsupport, l'ofwhich the platform is a part, each maintains the bar and knife attached thereto in an upright position rela-tively to the table, and dispenses with the necessity of employing for thisvpurpose some other support which is extraneous of the table.

The knife of the machine Vrepresented in the drawings is adapted to be worked Vu p and down or reciprocated through the intervention of the bar F. Hence the bar Fis tted to slide up IIO and down in the .bracket-piece 'v' of the platform; and on the lower end of the sleeve E (with which the bar F is connected) are secured two anges, e e, which straddle the end of a lever, f, to which an oscillating motion is imparted by an eccentric, g, or by any other suitable mechanism. As the lever f oscillates, it imparts to the sleeve E and bar F a reciprocating rising and falling lnotion. The eccentric g revolves on the rod b, motion being imparted to it by hand, foot, or any other power, through the intervention of the driving-pulley K, which, being tted to revolve on the rod b, has a stationary or fixed relationship to the surface of the table A while the sheet of cloth upon the table is being cut. If foot-power is used, I employ a treadle, h, which is hung at or near the center of its length, so that motion can be imparted to it in one direction by depressing the toes of thefoot, and in the other direction by depressing the heel. The treadle Yin the form shown in Fig. 6.

operates the crank-pin n ofthe crank-shaft M, from which the power is conveyed to the driving-pulley K by means of a belt, m. The eccentric g, eccentric-rod g', lever f, dan ges e e, sleeve E, and bar F constitute, in this machine, the combining mechanism between the knife (which swivels with the platform and cloth-support relatively to the table) and the drivingpulley K, (which, while revolving, has a fixed relationship to the table or is stationary,) so that the power exerted upon the fixed dri vin gpulley is transmitted to the knife, however it may be swiveled over the table, to cause its cutting-edge to correspond with the direction of the line to be cut in the material.

The knife G is stamped out of sheet metal, It presents a double cutting-edge, so that it may be removed and reversed, and on its 'back edge is formed a spring-catch, i, so that when the shank of the knife is pushed through its mortise in the bar F said spring` will catch over the rear edge of the bar and ret-ain the knife iirmly in positio'n. The knife is held by said bar with the plane of the knife-body upright or at right angles to the surface of the table A, on which the material to be cutis supported, and in the same position relatively to the swiveling cloth-support, composed of the platform B and socket H. As the knife descends it enters the socket H, which is firmly connected with the turning platform B by being secured to the hanger U, and the top of which presents double cuttingedges, either of which is brought into operation, according to theposition ofthe knife. The material to be cnt, on being fed over the swiveling platform and under the knife, rests upon the top of the socket, close to the plane ot' movement of the cutting-edge ofthe knife, and as the knife descends the material is cut by the action of the cutting-edge of the knife operating upon the material supported crosswise beneath it by the edges of the socket- The socket is secured to the hanger C by set-screws 'a2 a2, passing through slots b2 b2', Fig. 1, so that the vertical relationship between the upper surface of the socket (which is a part of the swiveling cloth-support) and the body of the knife may be adjusted to place the surface of the swiveling cloth-support, which is close to the track of the cutting-edge, in the proper vertical relationship to that edge, notwithstanding the wearing away ofthe knife-edge by grinding it.

In the socket works the clearer I, which is firmly secured to the bar F, and passes into the `a bell-crank lever, k l.

Yor fastene which are shown in Fig. 7. This feed-dog` straddles the bar F, and its serrated front end is supported by a lever, j, Fig. 1,which is piv- .oted at one end to the hanger C, while its loose end bears upon the cam-shaped end kof This bell-crank lever has itsfulcrum on a pivot, m, secured in a bracket attached to the hanger C, and its arm lis provided with a slot, o, which st-raddles a pin, p, secured in the bar F. In the end of the arm l is secured a friction-roller, q, that bears against the edge of a lever, r, said lever being pressed up against the friction roller by a spring. s. (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 when the friction-roller rises it imparts to the lever 1' an oscillating motion, and therebythe feed-dog is carried forward toward the knife G; but before this forward motion' of the feed-dog takes place the cam-shaped end of the arm k of the elbow-lever causes the lever j, and with it the feed-dog J, to rise, so that the teeth ot' said feed-dog will take hold of the material to`be cut and be in position to carry said material along when the forward motion of the feed-dog takes place. A spring, t, (see Fig. 4,) which actsY 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 hook-shaped end of said feed-dog up against the lever r. When the bar F rises, therefore, the feed -dog is'irst caused to take hold ofthe 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 to recede, ready fora new move.

The bar F is extended a certain distance beyond the mortiseintended to receive the knife, so that the upper end of said bar may form the guide for the tubular shank ofthe presser-foot K. This presser-foot straddles the knife, and it is depressed by lthe action of two springs, u u, one on each side, so as to produce a uniform action. These springs are hitched at their botfem ends to a wire passing through din the bar F, and their upper ends catch over thetop edge of the tubular shank of the presser-foot. By the action ofthe presser-foot the material to be cut is kept down' IOO IIO

by means of a handle, lv, which is hinged to its shank, and which also acts as a stop to retain the foot in its elevated position. For this purpose it is brought to bear upon the edge of a handle, ir.

From the platform B rise two mold-boardlike` iianges,'a', one ony each side of vthe bar F,A

and close to the same, for the purpose Vof throwing off the material after it has been cut, and preventing the same from crowding against the sides of the bar F. 5

The platform B is provided atits 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 outer end a handle,f, and which is below the surface of the table. By pushingin this rod the pinion d is thrown int gear with the rack b', and the platform B: cab be swiveled or turned laterally by turning the handle j", in place of being turned g by the handle w or by the foot-piece c, as before described.

r1 he material to be cnt is adjusted on the swiveling cloth-support, (composed ofthe platform B'and socket H,\under the presser-foot, and by imparting to the cutter-bar a reciprocating motion the operation of cutting is effected.

1f the knife is to follow a curved path and the piece to be cutis small, the swiveling clothsupport 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 swiveling cloth-support, either by hand or by foot, causing the knife to follow the outlines of the pattern previously marked on the material.

This machineis principallyinteuded forlarge clothing-manufacturers, and it is capable of cutting at one operation through twenty or.

more thicknesses of cloth or other textile fabrics, or through a still larger number of thicknesses of paper, or through several thicknesses of leather. The manipulation ofthe machine is quite simple, and its operation is exceedingly rapid, so that it produces a great saving in hand-labor..

It must he remarked that for different kinds It may, for instance, be made to act as a punch or a button-hole cutter, or as a cutter of any other description. Thus, for-example, the knife may be made with a` serrated or saw edge, as represented at Fig. 8, which represents a cutter thatwas tiled in the United States Patent Oflce wit-h my model when making my application for the original patent.
