IMPROVEMENT IN CLOTHMEASURING MACHINES.

Specification forming part of Letters Patent No. 164,094, dated June 8,1875; application filed April 9, 1875.

To ail 'whom it may concern:

Be it known that I, MARK KNOTT, of Willimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements pertaining to Cloth- Measuring Machines, of which the following is a specication, reference being had to the accompanying drawings, where- Figure 1 is a side elevation of the upper part of a cloth-measuring machine having my improvements attached, with the presser-bar down upon the cloth-roll. Fig. 2 is a rear elevation of the same parts in the same adjustment. Fig. 3 is a rear elevation of the same parts, with the presser-bar lifted from the cloth-roll.

Where cassimere or other cloth is made, machines are used to measure the cloth and fold it into package form for market.

In a machine for this purpose, which is much used, the cloth passes, in the direction indicated by the arrow, over the roll a, which is hung in the frame b, having the presser-bar c held down upon it by pressure of a spring or gravity. A workman has to raise this presserbar about seven or eight hundred times a day, and hold it raised while he adjusts the cloth under it-a matter of great inconvenience.

My invention is a device for greatly lightening this labor.

The letter a denotes a cloth-roll; b, the frame of the machine; c, the presser-bar, hung by rod c from shaft cl; c, a lever fastened to shaft d; f, a spring, pulling the presser-bar down Jupon the cloth-roll; g, a cord or chain attached to rear end of lever e, running down around the pulley h, and attached to the sliding bar z' through the medium 0f the arm j. The bar i slides back and forth in the mortised supports k k', being pulled toward the side A by the spring m. The spring-handle n has a shoulder, nf, which will catch on the support lc when the barfis pulled forward, so as to let down the presser-bar, and will thus hold 'the bart' in this adjustment. By simply raising the handle n, the shoulder n is disengaged from its hold on the support 7c, aud the spring m will draw it back, thus raising the presser-bar. Then the workman, to throw the presser-bar down upon the cloth-roll, has only to grasp the knob of the spring-handle a, and draw it toward him, and the handle, being a downward-bearing spring, will lock itself into position; and to lift the presser-bar, he has but to slightly lift the handle u, when the bar i will iiy back and lift the presser-bar.

I claim as my inventionl. The combination of the cloth-roll a, presser-bar c, rod c', shaft d, lever e, and spring f, all operating substantially as shown, for the purpose set forth.

2. The combination of the shaft d, bearing the presser-bar, lever e, spring f, chain g, pulley h, and sliding bar i, all operating substantially as shown, for the purpose set forth.

i 3. The combination of the shaft d, bearing the presser-bar, lever e, chain g, pulley h, sliding bar t', spring m, and spring-handle, having the shoulder n', all operating substantially as shown, for the purpose set forth.

MARK KNOTT.
