MORRIS GROSSMANN, OF ST. LOUIS, MISSOURI.

MACHINE FOR CUTTING CLOTH.

SPECIFICATION forming part of Letters Patent No. 467,407, dated January 19, 1892.

Application filed November 23, 1891. Serial No. 412,798. (No model.)

To all whom it may concern:

Be it known that I, MORRIS GRossMANN, of the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Machines for Cutting Cloth or earing-Apparel, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in machines for cutting cloth or wearing-apparel; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

In the drawings, Figure l is a perspective View of my complete invention. Fig. 2 is a bottom plan View of the plate which carries the knives and their attachments. Fig. 3 is a vertical sectional view, with parts broken away, taken through the gearing; and Fig. 4: is a vertical section taken throughone of the knives or cutters and the holder for the same.

My invention is especially applicable for the cutting of men-s garments, but can be used to cut dress-forms of all kinds, corsets, neckties, cloaks, under-garments, and the application to any other form that may be deemed desirable.

The invention that I am about to describe may be partially constructed of wood or entirely of metal. This of course is immaterial.

Referring to the drawings, 1 represents a stand, which is composed of a bed 2, and said bed supported upon the floor by the use of six legs 3, said legs projecting a suitable distance above the bed2 of the table, upon which ends cross-pieces 4rare securely fastened, and which pieces receive the weight and strain applied to the machine.

5 represents a movable plate, which is adapted to move to and from the bed 2, or, in other words, in a vertical direction, and is guided in its movement by the upper ends of the supports 3, as shown in Fig. l of the drawings.

6 represents a horizontal shaft, which is suitably mounted in bearings '7, which are carried by the cross-pieces 4. Said shaft is adapted to rotate and operate the other mech anism, as hereinafter described. To one end of the shaft 6 is secured a crank 8 or any other suitable device for rotating the shaft 6 by hand, or said shaft may be provided with a belt-pulley 9 in the region of its length, by means of which the said shaft may be re volved by steam or other power. Upon the shaft 6 are mounted and keyed thereto three worms 10, which worms mesh with wormwheels 11, located in a horizontal plane with the said worms 10.

12 represents three screw-threaded posts, the lower ends of which are securely fastened by bolts or otherwise to the upper surface of the movable plate 5, and the upper ends passing through suitable holes formed in the crosspieces 4, and which are adapted to freely move therein. The worm-wheels 11 have a center bore 13, and the said bore is provided with threads, which threads correspond with the threads formed upon the upright posts 12, which, when the Worm-wheels 11 are operated or rotated, will be elevated or lowered, and consequently impart a corresponding movement to the plate 5.

14 represents brackets, which are supported by the cross-pieces 4, the bearings 15 of which encircle the upper ends of the upright posts 12, thus holding the worm-wheels 11 in their proper position and location to the crosspieces 4.

By the construction of the mechanism be fore described when motion is imparted to the shaft 6 the worm-Wheels 11 will be rotated,causing the plate5 to either be lowered or raised, as may be desired.

Fig. 2 shows more plainly the location and construction of the knives or cutters as applied to the under surface of the movable plate 5.

16 represents holders, which are so shaped as to conform to the shape of the pattern or goods to be out, the under surface of which is provided with an annular groove 17, within which groove the knife or cutter is held firmly. The knife or cutter 18 is constructed, preferably, of steel and is provided with a cutting edge 19, the opposite edge of which isinserted in the annular groove 17, formed in the knifeholder 16.

Any suitable number of tightening-bolts 20 are employed, one end of which bears against the side of the knife, by means of which the saidknife is held firmly to the knife-holders 16.

The knives 18 are of the same shape as the holders 16, and said holders are of any suitable shapenamely, the shape of the pattern to be out.

To the top of the knife-holders 16 are secured screwthreaded thimbles 21, which thimbles are adapted to pass through suitable openings 22, formed in the plate 5, and by means of thumb-nuts 23. said knife-holders are securely held to the said plate 5.

24 represents a plate, which is preferably of the shape of the knife-holder carrying the same, which plate is adapted to move vertically within the space surrounded by the knives 18. To said plate is secured an upright post or stem 25, which passes through the screw-threaded collar 21, by means of which the said plate 2i is guided.

26 represents coil-springs, which are connected to the plate 24 and the knife-holder 16,-th'ey beinginterposed between the two, and tend to always hold the plate 24 in the position as shown in Fig. 4 of the drawings. By this construction, after the knives have been passed through the cloth in cutting, the said plates 24: will press the cloth out of and from contact with said knives. If the latter were not used, the cloth would remain within the space formed by the knives.

In applying my device to the cloth to be cut the said cloth is laid up in the usual Way and placed upon the bed 2 of the table immediately below the knife or knives 18.

When power is imparted or applied to the shaft 6 by hand or other power, the said knives will be brought in contact with the cloth so placed ,upon the bed 2 of the table, and thereby cut from said cloth the shape desired to complete a garment.

To facilitate the work necessary in carryin g out my invention, I may employ two ordinary tables, one on each side of my device, on

one of which I place a removable board or slab, upon which the goods or cloth to be cut is placed before it is fed to the machine, and the other table to receive the goods or cloth after it comes from the machine. By this means the goods or cloth is placed in position upon the board to be fed to the machine, and

i said cloth can be easily fed under the knife and taken from under said knives after the cloth has been out without handling the same.

Having fully described my invention, what I claim is- 1. A machine for cutting cloth, consisting of a plate 5, a knife-holder, a thimble projecting from the knife-holder and secured in an opening in the plate 5 for supporting the holder, a knife secured to the holder, a yielding plate within the knife, and a guide-stem projecting from the yielding plate and passing through the thimble, substantially as set forth.

2. A machine for cutting cloth, consisting of a support or table upon which the cloth to be cut is placed, a movableplate 5, a knife or knives 18, adapted to be brought in contact with the cloth placed upon the table, a shaft 6, provided with worms 10, worm-wheels 11, adapted to mesh with the said worms 10, bores 13, formed in the said worm-wheels 11 and provided with screw-threads, uprights 12, secured to the movable plate 5 and provided with screw-threads, which threads mesh with the threads formed in the bores 13, and a crank or other device mounted upon the said shaft 6 for imparting motion thereto, substantially asset forth.

In testimony whereof I affix my signature in
