BARNETT RUBINSTEIN, OF ST. LOUIS, MISSOURI.

CLAMP FOR CLOTH-MACHINES.

Specification of Letters Patent.

Patented Aug. 30, 1921.

Application filed June 16, 1919. Serial No. 304,680.

To all to from it may concern Be it known that I, BARNETT RUBINSTEIN, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a certain new and useful Improvement in Clamps for Cloth-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of my improved cloth holding machine.

Fig. 2 is side olevational view of the same.

Fig. same.

Fig. 4- is a cross-section of the same, and,

Fig. 5 is a detail view showing the machine in operation.

This invention relates to a new and useful improvement in cloth holding machines, the object being to hold the pieces of cloth in position while they are being printed or cut. Heretofore, in machines of this character, it has usually been the practice to hinge the clamping member with the result that the cloth would be slightly displaced when the clamping member was folded over onto the cloth.

In the drawings, 1 indicates the work table of a cloth machine on which are arranged pieces of cloth X to be printed or cut. These are usually extended between and held in position by guides 2.

In Fig. 5 I have shown a printing head for printing the neckba-nds of collars, the work table being shown unprovided with 3 is a longitudinal section of the guides. The printing head or cutting devices form no part of my invention.

5 indicates my improved cloth clamp having a handle 6 on its upper side, said cloth clamp carrying two rods or standards 7 which pass through openings in the work table 1. The lower ends of the rods carry a bar 8 which is adjustably secured thereon by means of nuts 9 which serve as jam nuts and by which the bar 8 is made adjustable and against which impinge washers 10 above which are arranged springs 11 whose upper ends bear on the underside of the work table.

12 indicates brackets secured to the bar 8 between which is a link 13, said link being arranged between the forks of the end of a lever 14 pivotally mounted between brackets 15 and secured to the under side of the work table 1. The opposite end of this lever 14 is connected by a rod 16 to a foot treadle 17 whereby the operator may lift the clamping plate 5 and insert the, work thereunder, and upon releasing the foot treadle hold the work in position.

It will be noted that the clamping plate or bar 5 is guided at two points by the rod 7 which straddle the goods and that the lever 14 is connected to the middle portion 'of the connecting bar 8 whereby when the clamping plate 5 is lifted. it is practically evenly balanced. The adjustability of the compression of the springs 11 is also desirable, as in this way the various thicknesses of goods may be compensated for.

What I claim is:

In a cloth clamp, the combination of a work table, a clamping bar, a centrally arranged handle thereon, rods carried by the ends of the bar-and extending through the work table, springs cooperating with the rods and tending to force the bar toward the table, a bar connecting the lower ends of said rods, a foot-operated lever, and a link connecting said foot-operated lever and the center of said connecting bar.

In testimony whereof I hereunto affix my signature this ltth day of June, 1919.

BARNETT RUBINSTEIN.
