MEANS FOR STOPPING LOONlS AT INTERVALS.

(SPECIFICATION forming part of Letters Patent No. 704,436, dated July 8, 1902.

I Application filed December 3, 1901. Serial No. 84,508. (No model) To all whom, it iii/(by concern: (See Fi 1 a d The 1 1; is of Beit known that LGEORGE A. OLUFF, acitithe usual construction-11amely, it is in the zen of the United States, and a resident of form of a disk with worm-teeth on this disk Paterson, in the county of Passaic and State meshing with the shaft 1). 5 of New Jersey, have invented a new and.

This cam is so locatedon 2o sumed, the result of which operation is that the disk 0 that when ten yards are indicated the ribbon will have a small part at each ten thereby the cam runs under a lever 02', fasyards in which there is no filling, this part tened'to the clock-frame c by a clamp 61*. serving as a mark for subsequently cutting (See Fig. 6.) The lever d is connected by a the ribbon into the ten-yards length referred cord d to the counterweighted carrier 6 of 25 to above. the hook f.

The worm-shaft b is but when the carrier falls to the active positoo 50 mounted to turn in the frame 0 of the clock tion shown in Fig. 4 the bill of the hook is e, such frame beingheld in place byabracket lowered into the path of the eye it, and as or eye h.

the eye moves forward it engages the hook and draws the same longitudinally backward as the batten returns. The hook is mounted to slide longitudinally in the carrier 6, thus allowing for the above-described movement. The hookfhas a cord f attached, such cord running around a pulley f on the frame 6 of the carrier 6. This cord then passes over guide-pulleys f which may be arranged in any suitable manner, and the cord is finally connected to the shipper t' of the loom. f indicates a spring which holds the hook f normally in its forward position. (See Fig. 2;) The shippert'is connected with the mechanism for'st-opping and starting the loom, so that when the hookf is drawn backward and strain is placed on the cord f the shipper is moved to throw the loom out of action.

When the loom is started, the parts are placed in the position shown in Fig. 1, and when ten yards of work or any other length desired are wound on the cloth-beam the cam 01 will automatically actuate the lever d and throw the carrier 6, so as to allow the stop g to disengage itself. Then the carrier drops, so that the hookfis actuated to stop the loom. The operative of the loom may now perform suchoperations as are necessary to make the well-known mark in the ribbon, as illustrated in Fig. 8, and'then the operation of the loom is again started by throwing up the carrier e and disengaging the hook J from the staple The dog or stop 9 is then returned to its active position, and the parts again assume the adjustment shown in Fig. 1.

The advantage of this invention is that it automatically stops the loom the instant that the desired quantity of ribbon or other fabric has been woven. It does not depend upon the care of an operative in watching a device which merely indicates the number of yards woven. In the old apparatus as commonly employed the operative was called upon to watch the indicator and stop the loom when the proper number of yards had been woven. In frequent instances the operator will allow the loom to go on past the necessary number of yards, and then the ribbon has to be unwound and measured.

Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all forms of the invention as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 7 1.
