CLOTH-CUTTING M'A'CHIN E.

srncrnzcemon forming part of Letters retentive; 725,391, dated April 14, 1903,

Application tiled December 17,1901. seen No, 36,295. i (in model.)

To all whom it may concern! 1 Be it known that I, CHARLES A. AMEIZANG,

a citizen of the United States, residing at'Baltimore, State of Maryland, have invented certain new and useful Improvements in 01cm,

Cutting Machines, of which the following is aspecification.

This invention relates to cloth-outtingmachines; and one object of the invention 'is to provide a machine that will automatically cut out from the cloth shaped parts of garments such as, vest-fronts, coat fronts and backs, sleeves, trousers-legs, dispensing with hand-guided tools; and another object is to provide'pattern devices for controlling the cutting mechanism.v

The inventive idea' here involved may find; expression in various mechanical forms, and

I have for the purpose of illustrating the inventionshown one of such'forms in the accompanying drawings; but itis to be distinctly understood that said drawings. are intended for the purpose of illustration only and not as defining the limits or scope of the invention.

In said drawings, Figure 1 is a side elevae tion of the machine with parts'in section; Fig. 2 is an end elevation thereof with the upper parts in section on the line 2 2 of Fig. 1. Fig. 3 is a detail plan view of a portion of the cutting-block. Fig. 4 is-a plan View of one'form of pattern. for controlling the cut-. ting-knives, showing it secured to a belt by ne of the clamps.

Referring to the drawings by reference-letters, a designates an open framework, which may be placed adjacent the discharge end of a loom, sponging apparatus, or the like, and

which is provided with end posts a and upper and lower side bars, (designated a a respectively.)-

Supported above the framework a on the upper side barso, are two brackets b, in

which are journaled two pairs of idle rollers 0, extending across the machine and through which is fed the -cloth d that is to be out, as illustrated in the drawings. Between the two pairs of rollers c is a cutting-block e, detachably secured to the brackets by screws e and provided, as illustrated in Fig. 3, with a continuous longitudinal slot e and a series of cross-slots e extending approximately at right angles to-the continuous slot and comand the like--thereby" municati'ng therewith. The cross-slots e of a one series, extends across the machine with the ends of ktheir cutting edges g adjoining a complete transversecut entirely across or" each other so as to make, whenever desired,

partly across the cloth. The other seriesot knives, h, also extend across, but hav'etheir cutting edges h at right angles to and at the junction of every two knives of the firstnamed series, and each k'nifeof this secondseries registers with one of the slots in the cutting-blook-e. I

. Journaled between fihGilWO pairs of end posts a of the framework a are two. horizontal shafts i, each of which carries two pulleys t", .and endless beltsj are passed around said pulleys and are provided with clamps k, by means of which the pattern-sheet Z is secured against endwise and lateral movement. betweenthe said two belts, but is permitted a limitedup-and-down movement.

in order to impart an intermittent forward motion to thebelts carrying the pattern, two ratchet-wheels m are secure'd'on one of the said shafts '11, and spring-pressed pawls 01, mounted on-vibrating arms 0, engage 'with the teeth of said ratchet-wheels. The said arms 0 have one end pivoted,'as at o, and are vibrated by lneans of connecting-rods '10, secured to cranks shaft q.

to the pattern in addition to'the intermittent forward motion, the two upper side bars a of a the framea are each provided with two downp" on the main driving- In order to impart an up-and-down motion weirdly-projecting-han'gers r, to which togglehorizontally on said toggle-levers between the two side bars a and underneath the knifebrackets 12, and a linku connects the several toggle-levers and is itself connected to the levers s are connected. A tabletis supported.

upper end of the vibrating arm 0, so that as a vertical reciprocating motion. 1 By the arrangement of parts just described it will be seen that the pattern-sheet Z is given said arm vibrates the said table will be given L a step by-step forward motion in a horizontal sired article, and the limit of the up-and-down motion of the table is such that only those knives that are in alinement with the pattern will be thrust through the cloth. With this understanding it will be seen that as the pattern moves along underneath the knives it will repeatedly raise the necessaryknives far enough to make the desired cut. Forinstance, if a straight out across the cloth is desired only so many of the knives Q Will be raised far enough to make the necessary length of cut, if a cut in the direction of the length of the goods is desired one of the knives h will be repeatedly raised far enough until a cut ofthe required length isobtained, and if an oblique cut is desired the knives of one series will alternate in rising with the adjacent knives of the other series. Collars a; are secured to the knives to limit their downward movement. Said collars are shown in Fig. 1, but are not shown in Fig. 2, owing to the closeness of the lines representing the knives in said latter figure.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A machine for cutting out shaped parts of garments suchas vest-fronts, coat fronts and backs, and the like, having in combination with cutting mechanism, a pattern for the part to be cut and separate from said cut- These lugs engage ting mechanism, together with means for producing a relative movement between the pattern and cutting mechanism whereby the pattern actuates the cutting mechanism to cut out from the material the desired shaped part, as set forth. 2. In a cloth-cutting machine, a series of knives extending across the machine with their cutting edges adjoining; a second series of knives located at intervals across the machine with their cutting edges arranged at right angles to the first-named series and at the junction of every two knives of the firstnamed series; and pattern devices for automatically actuating said knives of either series, substantially as set forth. 3. Inacloth-cutting machine, the combination of the framework; the brackets supported above said framework; cloth-feeding rollers journaled in said brackets; a cuttingblock secured to said brackets at one sideof the path of the cloth, between said rollers; vertically-movable knives mounted between said brackets at the other side of the path of the cloth; a table underneath said knives; toggle-levers connected to the framework and supporting said table; means for actuating said toggle-levers whereby to vertically reciprocate said table; and a pattern intermittently movable in a horizontal direction and adapted to pass between said knives and table, as and for the purpose set forth.

In testimony whereof I aflix my signature in the presence of two witnesses.

CHARLES A. AMELANG.
