IMPROVEMENT IN MACHINES FOR CUTTING TEXTILE AND OTHER MATERIALS.

Specification forming part of Letters Patent No. EL, dated May 26, 1874; application filed April 22, 1874.

To all whom it may concern: v

Bc it known that I, ALBIN VVARTI-I, of Stapleton, in the county of Richmond and State of New York, have invented a new and useful Improvement in Machines for Cutting Textile and other Materials; and I do hereby declare the following to be a full, clear, and eX- act description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this speeication, in which drawing- Figure l represents a longitudinal vertical section of this invention. Fig. 2 is a side view of the same. Fie. 3 is a horizontal section of the same in the plane x, Fig. 2. Fig. 4 is a sectional front view of the same when the cutting-machine is fastened to the table. Fig. 5 is a rear view of the mechanism for imparting motion to the cutting mechanism, in a smaller scale than the previous figures. Fig. 6 is a plan or top view of this driving mechanism. Fig. 7 is a transverse section of a modification 0f the same. Fig. 8 is a rear view of the same. Fig. 9 is a partial front view of the same.

anism can be made to follow the lines of theV pattern to be cut out, while the material from which'said pattern is to be cut remains stationary on the cutting-board. My present improvement consists in the arrangement of a cutter-bar, a presser-bar, and a feed-bar in the interior of a standard which rises from a platforni and carries a handle for turning said standard, and another handle for governing the position of the presser-bar and of the feedwheel, which is attached to said presser-bar in such a manner that the entire cutting and feed mechanism is condensed into the smallest possible space. Said standard is guided in the end of a tubular arm which forms the bearings for the driving-shaft that imparts a reciprocating motion to a slide which engages with a sleeve fitted on the standard inclosing the cutter-bar, `thefeed-bar, and the presserbar, and made to catch over a nose projecting from the cutter-bar, so that the standard can be freely turned in either direction without throwing the cutter-bar out of gear with the drivin g-shaft. The arm which supports the standard inclosing the cutter-bar, the presserbar, and the feed-barextends from a head which has its bearings in a carriage that can be made to travel along the cutting-table by means of an endless belt, said tubular swivel-head forming the bearings for a shaft on which are mounted two pulleys, one to receive motiony from the driving-belt of the carriage and the other to transmit the motion, by a belt and guide-pulleys, to the driving-shaft of the cutting mechanism in such a manner that, by the action of the carriage and the swivelhead, the cutting mechanism canl be made to act on any portion of the material secured to the cutting-board.

In the drawing, the letter A designates a platform, which may be made circular, or of any other desirable form or shape, and which forms the support for a standard, B, which is provided with a foot, C, that is secured in said platform by screws or any other suitable means. This standard is furnished with two guide-grooves, one for the cutter-bar D and the other for the presser-bar E. Boththese bars extend beyond the ends of the standard, and to the lower end of the cutter-bari) is secured the knife F, which is guided between sharp -edged anges c ofv the foot C, Vand works through a 4slot or receiver, b, in said AAfoot, so that its cutting-edge is steadie'd and enabled to pass clear through the material to be cut. The presser-bar E is U-shaped in its cross-section, so as to secure great strength and prevent bending, (Fig. 3,) and to its bottom end is secured the feed-wheel G and the protector H. This protector straddles the front edge of the knife, and it also acts as an indicator, to show the line of' the out. The feed-wheel turns on a pin, c, which is secured in the presser-bar, and it is depressed upon the material to be cut by a spring', d, which acts through a lever, I, on the presser-bar. Said lever has its fulcrum on a pivot, c, Fig. l, which is secured in an arm, J, proj ecting from the standard B, and to this arm is fastened a handle, K, that serves to turn the standard together with the entire cutting mechanism. In the arm J' is secured a set-screw, f, the head of which catches over the edge of the lever I, and prevents the same, together with the presser-bar, from following the action of the spring d beyond the desired point. By adjusting this setscrew, the distance of the feed-wheel G from the surface of the platform A, or from the surface of the foot of the standard B, can be regulated. By depressing the end of the lever I the feed-wheel is raised.

In the channel formed by the U-shaped presser-bar E is situated the feed-bar L, Figs. 2 and 3, which is depressed by the action of a spring, g. To the lower end of this feed-bar is pivoted a hook-pawl, h, which is held in gear by a spring, 1'., with aratchet-wheel, j, secured to the side of the feed-wheel G, and a stoppawl, 7c, prevents the retrograde movement of the feed-wheel. On the upper end of the feedbar is secured a head, Z, which connects by a rod, m, with a bell-crank lever, u o, that turns on a pivot, p, andthe arm o of which carries a friction-roller q, that bears against a cam-plate, M, secured to the cutter-bar D. /Vhen the cutter-bar rises, the bell-crank lever u o swings out in the direction of the arrow marked near it, in Fig. 2, and the feed-bar is raised, causing the feed-wheel to revolve in the direction of the arrow marked on it, in Fig. 2, and the material to be cut is carried in under the knife, or the machine is carried toward the material. /Vhen the cutter-bar descends, the feed-bar falls back and the pawl h takes a fresh hold. The cam-plate M is adjustable on the cutterbar (see Fig. l)for the purpose of increasing or diminishing the feed motion.

In the foot of the standard B are mounted one or two rollers, r 1^, Fig. 4, which are opposite the feed-wheel, and if two of such rollers are used I place them somewhat apart from each other, so that the feed-wheel presses the work between them, and a correct feed is insured.

The standard B extends up through eyes s s, formed in a bracket, N, which is secured to the end of a tubular arm, O, through which extends the driving-shaft I. On the end of this shaft is secured a disk, t, which connects by an eccentric wrist-pin, u, and rod o, with a slide, Q, Figs. l and 3, that moves up and down between guides in the bracket N. Said slide is provided with two lips, al. al, which straddle a flange, b1, on the upper end of a sleeve, R, which is fitted loosely on the standard B, so that when the slide Q receives a reciprocating motion, the sleeve B is compelled to move with it. From the cutter-bar extends a nose, c1, which projects through a slot in the sleeve, so that, by the action ofthe shaft P, slide Q, and sleeve It, a reciprocating motion is imparted to the cutter-bar. At the same time the sleeve is compelled to turn round with the standard B whenever this standard is turned 5 but if the sleeve turns, its flange b1 remains in gear with the lips of the slide Q, and thc motion of the slide is transmitted to the cutter-bar, whatever may be the position of the standard. The arm O is secured in a head, S, Fig. 5, which rises from a carriage, T, that moves on a guide-rod, U, secured to the cutting-board V. Through the head S extends a vertical shaft, W, on which are mounted two pulleys, d1 el, one of which engages with a belt, fl, that is stretched over pulleys g1 h1, secured on spindles i1j1,the bearings of which are fastened to the cuttingboard. The spindle il also carries apulley, k', which connects by a belt, Z', with a pulley, fm', mounted on the main shaft X. In the head S are secured two tension-pulleys, a af, and a spring-catch, o', which is fastened to the carriage T, and, engaging with a notched disk, p', in the head S, serves to adjust said head according' to the tension desired. As the beltfl acts on the pulley d1 it imparts to the vertical shaft W a revolving motion, andl this motion is transmitted to the driving-shaft I of the cutting mechanism by a belt, q, which passes over guide-pulleys s mounted on said driving-shaft. (See Fig. I.)

By this arrangement the cutting mechanism can be moved over any portion ofthe cuttingboard without throwing it out of gear with the belt f1, and the cutting-edge of the knife can be made to follow the sinuosities or contours of any pattern that may be marked out on the material placed on said cutting-board. If desired the beltj'1 can be so adjusted that it imparts to the carriage T a sliding motion on the rod U, while the vertical shaft W remains stationary, and begins to move only when the carriage is retained stationary against the action of the belt f1, and in this case the cutting mechanism is carried automatically over the cutting-board.

The carriage T, instead of being guided on a rod, U, as shown in Figs. 5 and 6, may be arranged on the side of the cutting-board, and made to run ou guide-rails o o', (see Figs. 7 and 8,) one of which is fastened to the floor, and the other to the edge of the cutting-board. In this case the head S is fastened to the side of the carriage, and the belt fl acts on the pulley d1 in the saine manner as previously described. If desired, a step-by-step motion may be imparted to the carriage by means of a pawl, c2, (see Figs. 8 and 9,) which acts on a toothed rack, b2, secured to the side of the cutting-board, said pawl being secured to a lever, c2, which receives an oscillating motion by an eccentric, d2, mounted on a shaft, c2, which extends through the carriage T, and on which is secured a worm-wheel, f2, that gears in an endless screw, g2, on the vertical shaft WV. Said pawl can be made to act on the rack b2 in either direction, or, if it is desired to impart to the carriage a continuous motion, or to retain said carriage in a stationary position, it can be thrown out of gear with the rack. On the shaft c2 is also mounted a pulley, 7a2, and another pulley, t?, is secured to a stud fastened in the carriage. Round these two pulleys extends a stationary belt, )'2, the ends of which are fast to the feet of the cutting-board, and,

as the pulley h2 receives a slow revolving mo tion, the carriage is caused to move along on the belt f2. NVhen this belt is used the paivl a2 must be thrown out of gear with the rack b2.

For certain classes of Work the platform A may be talgen off, and the foot C ofthe standard B Will in this case move under the material to be cut, or the material may be moved over said foot.

If desired, the platform A may be fastened to the cutting-board, and for this purpose I have provided the same with short feet t', (see Fig. 4,) which can be made to en gage with sockets u formed in a plate, Y, that is secured to the cutting-board by a nut or any other suitable means. If the platform is thus secured, the material to be cut is carried to the knife by the action of the feed-Wheel, and the direction of the cut must be governed by turning the Work according to the con tours of the pattern.

' If desired, the head S may be firmly secured to the carriage T, so that the 'cuttingmachine is carried along by the carriage in a rectilinear direction over the cutting-board. The arm O which carries the Cuttingmachine may be rigid or jointed.

What I claim as new, and desire to secure by Letters Patent, is
