This invention consists in the combination of a cutter -liead containing afre'ciprocating 'knife with' a "foot-plate, which sustains 'the Y cutter-head', and i which, Adnrin g y the operation of cuttin'g,"suipports the lInaterial'to; be cut', the whole' being capableot' being 'moved in any desired direction; also, in combining with 'y a knife-carrier a lrevolvin g 'and sliding shaft, said knife-,carrierbeing allowed-to' turnroundf an axis at right angles tov the' direction of the sliding shaft'in such a manner that by saidshaft the requiredmotion is imparted 'to the knife, and at the same time the knife-carrier, together with the knife, can be carried i'n any direction against'the material to be cut;y also,

in the combination of a presser-roller with 'a cutter-head containing -a 'reciprocating knife, and 'with' a foot-plate arranged to move-in any desired directio'n'iuv such a manner' that by the presser-rollerthe materialto be' cut is held down' upon the foot-plate vasthe same is j advanc'ed or moved-under 'the material to be cut; further, in combining with the -knife-carrying bara' hollow tubular guide-rodor cylindeiyto which is secured a handle in such a rod'the knife'ca'n be made to'follow the'4 sinu.

combination, 'witha cutter-head containing a reciprocating knife, of agfoot-plate, provided :with .a socketyone or both edges of which form cutting-edges to co-operatewith the edge of the knife, `the-whole being arranged to move inany desired direction further, in the combinatiomvwith'a cutter-head containing a re :ciprocating knife,vand with afoot-plate supporting the cutter-head, vand provided with a knife-receiving socket. of a bracket, 'which is grooved to form .a .guide forthe knife', and

prevents the knife from being twisted during the operation of-cntting.; a-lso, in a hinged vleverconnected -tothe bracket `of vthe foot- `plate,.and forming the 4bearing for a pin, which supports the presser-roller, in combination with acam, whichreceives a rotary moi tionfrom the' sliding revolving shaft, and from -whichniotiouf'is transmitted to the presserroller in sucha manner that the presserroller =is always in gear --witlrthe sliding revolving shaft .in whatever position the foot-plate may -bebrought, and thatvby raising the hinged lever the presserroller can be adjusted to the thickness of the-material to becut, or lifted clear above said material; further, in a 'finger -or i-ndexhingedto the center-pin of the press.

er-roller', said pin being secured in a hinged lever,'while the finger extends in front of 'the knife for the' purpose of: indicating the direction in which the knife is to caty-also, in a uni' -versal swivel-head, in combination with the.

sliding and revolving shaft, and with the footplatecarrying the cutting mechanism in such a'manner that the sliding' and revolving shaft, together'with the parts attached to it, can be I swung orV Inoved in any desired direction without throwing itout-of gear with the' drivingshaft, and by these means the knife is free to accommodate itself to the .position or nature of the material to be cut; further-,inthe com-; zbination,- with Ythe vcutter-head containing' a reciprocating knife, and with a foot plate,

which supports thecutter-head, of on@ or more rollers, connectedto the 4under surface ofthefoot-plate t'o allow said foot-plate to move easily in any desired direction.-

In the drawing, the letter A designates a table, from which rise's the swivel-head B,

which'supports thelslidin g and revolving shaft' C.' vSaid swivel -A head consists of-a tubular standard, a, which is provided'with abottom flan ge, b, to tit into a grooved bracket, c, which is firmly secured to the table A, the tubular standard a being free to rotate in said bracket. In the mouth ofthe tubular standard is fitted a plate, d,which swings between center-points c, (see Fig. 3,) and from which rise two standards, f, that form the bearings for a tubular shaft, g. By means of the center-points c this shaft can be swung up or down, or brought in anydesired inclination toward the table A, while the tubular standard a allows the same to turn freely .in either direction in a planev parallel to the surface of the table. 0n 'the tubular shaft g is mounted a pulley, h, which connects by a belt, i, with a pulley, j, mounted on the driving-shaft D, that has its bearings in boxes secured to one of the legs of the table A, and which receives motion by a handcrank, or by a treadl, or by anysuit'able means. The-pulleys h and j are geared, so that when the standard a is turned round the belt t' will not be thrown olf.

The tubular shaft gis bored out to receive they sliding shaft U, which is by preference triangular, but which may be formed in any desirable manner, so that it will not'turnin the tubular shaft, whileit is free to slide therein. The sliding motion of the shaft C is facilitated by friction-rollers k, which project through the sides of the tubular shaft g, and bear from different sides against the sliding shaft C. (See Fig, 4.) One end of said sliding shaft is turned off round, and it has its bearing in a bracket, E, which extends from a sleeve', F, fitted on the cutter-head .or hollow guide-rod G of the knife-carrying bar H. This hollowL guide rod or cylinder is supported by a standard, I, which rises from the foot-plate J, said standard being provided with au annular bracket, Z, (see Fig. 1,) that is screwed up against a flange on the bottom end of the hollow guide-rod, and on said flange rests a double cogfwheel, K, which is dropped loosely on the hollow guide'rod beneath the sleeve Fsaid sleeve being bored out to receive the tubular hub of the cog-wheel. 'The u pper cogs of said cog-wheel gear into a pinion, m, mounted'on the end of the sliding shaft C, inside of the bracket E, said shaft being prevented fromv sliding in the bracket by the pinion on one, and by a screw-ring, n, on the other, side of the bracket. The lower set of cogs of the cog-wheel K gear into a pinion, o, which is mounted ou a shaft, p, that has its bearings in a bracket, q, extending from the standard I of the footplate. On this shaft is also secured a disk, rr, carrying an eccentric wristpin, that connects by a-rod, s, with theknit'ccarrying bar H, which moves up and down in grooves t in the hollow guide rod G, and asl the shaft C is revolved a reciprocating motion is imparted to the knife-carrying bar. L is the knife, which is by preference cut or stamped out of sheet metal, and which is secured to the bar H by screws or other suitable means, thefront edge of the knife being so adjusted that it coincides with the center line of the hollow guide-rod, so that by turning this guiderod, the front edge of the knife remains in the so that by this guide-groove the cutting-edge of the knif'e is caused to enter the knife-receiving socket without fail, and that in turning the cutting mechanism. during the operation of cutting thev knife is prevented from being twisted. Furthermore, the cutting-ed ge ofthe knife is inclined upward, so that the same, eveu if its point should become slightly twisted, will gradually enter the knife-receivin g socket, and the cutting-edge will not be injured. From the bracket q, which supports the shaft p, extends an arm, w, which terminates in a ring, and may serve as the handle for guiding the mechanism during the operation of cutting;

or, if desired, an additional handle, wl, may

be secured to the upper end of the tubular guide-rod G. (See Fig. 2.) the arm w is secured a lever, af,k one end of which' bears on the surface of a cam, bf, (see Figs. l and 6,) mounted on the shaft p, while its opposite end bears against thearm e of a bell-crank lever, c d', the arm d/ of which carries a pawl, e, that engages with the teeth ot' a ratchet-wheel, f. A spring, g*, which acts on the pawl e', serves to keep the lever a. in contact with the cam b. The ratchet-wheel f is mounted on a pin, g, and it is rmly connected to the presser-roller h', the pin g be ing secured in a lever` i', that swings on the shaft p on the side ofthe arm w, opposite to the lever a. (See Fig. 6.) Fromp this lever z" extends a thumb-piece, j, so that the same can be raised, while a spring, k', bears on said lever, and serves to depress the presser-roller h toward a serrated roller, l', which is mounted vin the foot-plate. A stop-pawl, m', prevents the ratchet-wheelf and the presser-roller h from turning in the wrong direction.

As the shaft p revolves, an intermittentI ro;

tary motion is imparted. to the presser-roller hf, and if the material to be cutis held stationary, the cutting mechanism is fed automatically toward said material, the foot-plate J being placed beneath it, so that by the cooperation of the cutting edges of the knife and of the throat the cutting is'el'ected.

-Butif'the cutting mechanism is moved to ward the material to be cnt, the presser-roller serves to hold lthe material down upon the foot-plate, so as to 'prevent it from rising up by the action of the knife.l The foot-plate is constructed with one 'or more rollers on its bottom surface, so that it will move more easy on the table A, and it On one side of patterns of any desired form or shape.

maybe curved, as shown in Fig. 2, or it may be made in the shape of a flat plate, either oblong or in any desirable form. During the operation of cutting', the foot-plate supports 'the material to be cut.

This machineis of particular lvalue for cutting out such goods, Where it is most convenient to move the cutting mechanism toward the material to be cut, and since the cutting mechanism can be readily moved or'turned in any desired direction, I am enabled to cut (ist n index or finger, m', which is hinged to the pin g', enables the Workman to guide the course of the knife with ease and facility. This index straddles the knife, and it bearsA down upon the material to be'cut by its own inherent gravity, being free to adjust itself` to the varying thickness of said material, While the pin g', which forms the bearing for the presserroller, and` also for said index, rises and falls in accordance with the increased or `diminished thickness ot' the material to be cut.

Vh-at I claim as new, and desire to secure by Letters Patent, is-

1. VThe combination of a cutter-head, containing a reciprocating knife with a foot-plate, which sustains the cutter-head, and which, during the operation of cutting, supports the material to be out, the whole being arranged to be moved in any desired direction, substantial'ly in the manner herein set forth.
