SPECIFICATION forming part of Letters Patent No. 244,985, dated August 2, 1881.

Application filed Aprll 8, 1881. (No model.) Patented in France March 8, 1879.

To all whom it may concern Be it known that I, OCTAVE LoN DEs- CHAMPS, of Paris, in the Republic of France, have invented Improvements in Machines for Cutting Out Tuiles, Laces, Valenciennes, Em-

broidery, Tarlatans, Ste., from' the webs on which they are manufactured,for which Ihave obtained Letters'Patent of France for fifteen years, dated March 8, 1879, No. 129,494; and I 1o do hereby declare that the following is a full and exact description thereof, reference being made to the accompanying drawings.

This invention relates to a new machine for cutting the edges of tulle, lace, valenciennes,

r 5 and all articles of a similar nature into ornamental or other forms. v i Y Y 1 The invention consists inthe new combination of parts-hereinafter more fully described.

In the accompanying drawings, Figure 1 2o represents a front elevation of my apparatus. Fig. 2 is an end view of the same; Fig. 3, the transverse section (fullsize) of the working parts, the blade,` and the roller. Figs. 4, 5, 6, and 7 show the blade complete and in detail, (natural size.) Figs. 8 and 9 show the handle for guiding the machine, (two-thirds size.)

Finally, Fig. 10 shows a moditcationfof theY knife-moving mechanism. Y

' The thread-cutting machine, Figs. l to 9, ha 3o its frame made of a steel-plate, a, or table supported by feet a of suitable shape and dimen sions, that are strengthened by bars at A cast-iron table, b, in size about like the plate a, is connected with and supported abovethe 3 5 latter by two supports, c c. Between the'supports c project from the table additional supports, d d, which form bearings for a shaft, e, carrying atapering pulley, f. The shaft e hangs in line with thej plane of the plate b, 4o which is slotted to receive it, as indicated in Fig. 3. The tablec carries blocks c3 and a4,

in which liesV a shaft, g, which carries at its inner end a cam, g, and at its outer end a grooved pulley,g2, as indicated in Fig. l. The pulley g2 receives motion from a pulley, h, keyed to the driving-shaft h. The latter is hung in the framing a of the machine. The shaft h' also carries a fixed pulley,rh2, aloose pulley, h3, and v at its inner end is provided-with a'crank, to

5o which is connected therod p of theqpedal p, f so that the machine can be worked either by Vis hung loose on the shaft a.

thatis set in a recess of the carrier..

power applied to the pulley h2 or by the foot on the pedal p. On the shaft 7L is also fixed a star-wheel, I, which, by a band or chain, communicates motion to atoothed wheel, j, mount- 5 5 ed upon an intermediate shaft, j. A pinion, jz, on the shaft j gears Vinto a toothed wheel, 7c, which, together with the tapering pulley 7c', The tapering pulley `k' is in line with the pulley f above it, 6o which it governs by a cord, which runs on one or other of the steps of said pulleys, according to the speed required. The supports d d also carry four guides, l', in which fit two horizontal sliding rods, l l, both connected at their right-hand ends by a cross-piece, on, to which is pivoted one end of a horizontal rack, n,

,Whose opposite end is guided in a mortise of a' crossbar, a', that is carried by one of the supports c. In front of and in the same hori- 7o zontal plane as this rack n is a rod, 0, grooved throughout its length to receive and guide the handle-support or carrier o', Figs. 8 and 9, said carrier o having a handle, M, and a toothed crown-wheel, o2, that gears into the rack n, as indicated in Fig. 8. The carrier o contains a vertical tube, 03, which carries the wheel o2, The stem ot' the handle Mis inserted into the lower end ofthe` tube o3, and held in place by a couple 8o of screws, as indicated in Fig. 9 5 but, if desired, the handle may be directly connected with the crown-wheel o2. By this arrangement the handle can be conveniently used to move the slides l Z in orout at will. 8'5

The rod o is firmly secured in place, being held at one end in a projection, l2, of the support d, and at the other end in the. cross-bar n. The sliding rods l l carry collars q, each of which is perforated vertically for the recep- 9o tion of an upright rod, fr, which I term the blade-carrier r. The blade-carrier r has upand-down motion imparted to it by suitable connection with the cam g. The blade-carrier 1", Fig. 3, is cylindrical, and has a screw- 95 thread at its upper end, for the reception of a nut, r. The upper end of the blade-carrier r is also made tubular, for thereceptionv of the cutting device. This cutter has a base, t, of oval section, which base supports the blade t', roo the same being a slender tapering spindle with rounded point. From the base vt projects downward a stud, t2, fitted into a tubular socket, t3, that is held in place by the screw t4, asin Fig. 4. The spindle or blade receiver t' has a longitudinal groove for the reception of the cutting-blade t", Fig. 7. The cutting device is placed on the blade carrier i', and the socket t3 is inserted and locked in the vertical cavity of the screw-threaded part ot' said rod. The blade t5 participates, therefore, in all the movements of the blade-carrier i', and is, more- Over, able to turn in the socket t3 around the axis of the blade-carrier r. By this rotary movement, eccentric to blade-carrier r, I am enabled to compel the blade to always present its cutting-edge to the threads to be separated, whether they are coarse or fine, while the rounded edges of the spindle or blade-receiver t guide the knife-edge so as to prevent its cutting the embroidery-threads or the borders.

The tulle to be out or edged is presented to the blade and fed along by rollers u and c. The roller a is mounted on the shaft e, and is covered with indiarubber or the like. The roller o is above the roller u. being hung in a frame, o, that is suspended from a goose-neck arm, a, of the framework by two spindles, o2, which pass through tubular screws c3, Fig. 3, that are secured in said goose-neck. The latter is supported on the elevated table b. The screws o3 contain within their cavities spiral springs that embrace the spindles o2 and hold the frame c down. Nuts r4 serve to compress the said springs to the requisite extent. By this means the regulation of the delivery of the band of material is effected, and may be made more or less energetic on one or other of its edges, according to the thickness of the design. In front of the two rollers u and o are two others, y and z. The roller `Q/is preferably of wood covered with india-rubber, or with roughened copper or other metal, and is hung in the plane of the table b, as shown in Fig. 3. The upper roller, s, is of metal, covered with india-rubber, and turns in small blocks, that are attached to springs e', which project from the frame o. A sheet of metal, T, Fig. 3, tinted or colored white, black, or such other shade as agrees with the white, black, or other colored ground of the tulle, is fixed in front of the roller u. It prevents fatiguing the eyes of the operator and allows him easily to follow the outline of the design.

The machine operates as follows: Having set the machine in motion, the bands to be cut are placed between the rollers u and o, after having introduced them between the first rollers y and .c by raising the latter. Fig. 3 shows the tulle in dotted lines. The operator guides the delivery of the tissue with his left hand and takes the handle M in his right hand, giving it partial and successive rotations right and left, and vice versa, so that the cuttingtool, which is moved up and down by the cam g, is at the same time moved horizontally backward and forward, according as the designs are regular or irregular. The rollers o and y may also be covered with india-rubber, or roller s only. The bands of tulle or other material may, however, be guided by means of any suitable mechanism.

When the designs are regular or uniformly varied the backward and forward movement may be imparted to the slides l l by aid of the mechanism represented in Fig. 10. As regards the cutter, its up-and-down motion, and the delivery of the tissues no alteration occurs in the construction previously described, and the same letters of reference indicate like parts.

The shaft e, prolonged beyond the tapering pulley f, bears the bevel-wheel A, which com municates motion to the pinion B, the axis of which bears the cone C. From this cone, by aid ofthe strap E, the motion passes to the parallel cone D. Above this latter the pinion D is Xed on the same axis. This pinion governs another, F', by an intermediary endless chain. The pinion F communicates with the axis of a cam, F, the bend of which receives through the springs G the contact of a roller, (not shown,) such roller being carried by arack, H, on which the two shafts l l abut, which guide and govern the blade-carrier r.

The rack H', guided in its case H2, is sus ceptible of rising and fallin g by turniu g thekey H3, which actuates it by a pinion. The roller carried by the rack can then rest on the cam at variable altitudes, and be moved backward and forward, more or less. Thus the horizontal backward-and-forward movement can be regulated according to the thickness of the design.

The cones G and D admit of increasing or decreasing the speed of the cam F-that is to say, render the horizontal backward-and-forward motion of the blade proportionate to the delivery of the tissue or (which amounts to the same) proportions the movements with the spaces ofthe design. The strap E may for this purpose rise and fall by turning the fly J, whose long threaded shaft governs a forked nut embracing the strap.

Fig. 10 show's an example of working the ap' paratus mechanically, and admits of cnttin g regular designs on lace, tulle, embroidery, Sac., without requiring a strict superintendence, quite doing away with hand-work and doing a vast amount of work.

I claiml. The combination of the vertically-reciproeatin g cutter t5 and its blade-receiver or holdin g-spindle t with the vertically-reciprocatin g blade-carrier r, cam g, and with the perforated collars q, slides l, and handle M, and with rollers for feeding the fabric, substantially as herein shown and described.
