TAKE-UP MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 732,436, dated June 30, 1903. Application filed November 14, 1901. Serial No. 82,236. (No model.)

To aZZ whom it may concern.-

Be it known thatI, OSCAR L. OWEN, a citizen of the United States, residing at Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Take-Up Motions for Looms, of which the following is a specification.

In the weaving of cloth in a loom when the shuttle has failed to lay a weft-thread the weft-fork connects with the weft-hammer and causes the-rock-shaft to be operated to disengage the shipper-lever, which now leads the belt from the tight pulley to the loose pulley and causes the loom to stop. During the interval of time between the movement of the rock-shaft and the stopping of the loom the mechanism of the loom continues to act. The take-up mechanism continues to take up cloth, although no filling nnay be supplied. Thin and imperfect cloth is therefore produced. I

The object of my invention is to'arrest the cloth take-up as soon asa fault is detected by the weft-fork; and to this end the invention consists in the peculiar and novel construction of the'take-up mechanism more fully set forth hereinafter.

Figure 1 is an end view showing the parts of the mechanism of the loom required to illustrate the invention. Fig. 2 is aplan view of part of the top of the loom, shown partly Fig. 3 is a side view, partly in section, of the latch-head by which the take up mechanism is held in the disengaged position. Fig. 4 is a bottom View of the bracket on which the latch-head is supported.

In carrying out my invention Iprovide the end of the cam-shaft on the loom with a bevelgear and with a bracket supporting a sleeve in which a shaft is rotatably supported. A bevel-gear on the shaft engages with the bevel-gear on the cam-shaft. On the sodriven shaft, which extends obliquely from the cam-shaft, a worm is secured which ongages with the ratchet-gear through which the sand-roll is operated. The oblique shaft is supported near its upper end in a bracket secured to the rock-shaft, so that when the rock-shaft is partly rotated by the detector mechanism the oblique shaft is raised out of engagement with the ratchet-gear and the take-up of the cloth is instantly arrested.

In the drawings, A-indicates the end frame of theloom; B, the breast-beam; b, the wefthammer; b, the weft-fork slide; b an arm connecting the weft-slide with the rock-shaft b and b the'usual spring-shipper. The camshaft ahas secured to it the bevel-gear a, and journaled on it the bracket (1 in the sleeve a of which is journaled the shaft a, on the lower end of whichis secured the bevel-gear a meshing with the bevel-gear a. The shaft a extends obliquely from the cam-shaft a toward the rock-shaft b and has secured to it the worm a formed to engage with the ratchetgear 0, with which the pawl 0 engages to hold the ratchet gear in the advanced position. On the shaft of the ratchetgear 0 is the pinion 0 which engages with the gear of the sand-roll. (Not shown.)

To the end of the rock-shaft b is secured the bracket b the opposite end of which is pivotally secured to the collar b embracing the shaft or, butloose on the same.

To the end frame A at the breast-beam B is secured the bracket d, the arm 01 of which is provided with the elongated opening (1 The edge (1 is undercut, so as to engage with the hook d of the latch-head d, the stud d of which is provided with flattened sides and extends through the elongated opening (1 in the arm at. The shaft a extends through the latch-head d? with a loose sliding fit. The collar d -is secured to the end of the shaft of.

To enable others skilled in the art to use my invention, I will now more fully describe its operation. When the parts arein the normally operative positions (shown in Fig. 1) and the loom is running, the worm a is in engagement with the ratchet-gear c, which controls the rotation of the sand-roll and the take-up of the cloth. The worm securely locks the ratchet-gear, so that it cannot be moved by hand, as is the case when the ratchetgear 0 is operated by a reciprocating pawl ICO per and the take-up of the cloth or the warp instantly arrested. The weaving of thin places in the cloth is avoided and the laborious back winding of the warp and cloth unnecessary. On releasing the latch-head d the worm engages with the ratchet-gear c and continues to take up the cloth as it is woven.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent In a loom, the combination with the ratchetgear 0, the shaft a journaled in a bracket supported on the cam-shaft, the bracket o the cam-shaft, and the gears a and a of therockshaft 11 forming part of the detector mechanism, the bracket b on the rock-shaft, the collar b the latch-head d loose on the shaft M, the bracket (1, and the beveled portion d on the bracket d, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
