CUT SIGNAL on INDICATOR Foe LOOMS.

SPECIFICATION forming part of Letters Patent No. 753,980, dated March 8, 1904.

Application filed December 2,1903. Serial No. 183,450. (No d l.)

vented an Improvement in Cut Signals or Indicators for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of simple means for automatically indicating or signaling to a weaver when a certain length or out of cloth has been woven, so that the out can be detached and a new one begun.

It is now common practice to indicate, usually by a paint-mark on the warp, during the beaming or other preparatory operation a certain number of yards of warp, these marks being termed cut-marks, so that when one of them appears in the woven cloth the weaver knows a out has been completed. When a weaver has charge of a number of looms, which may be from twelve to sixteen or more in the case of automatic looms, the cut-mark may pass unnoticed unless considerable care is extion a sufiicient portion of a loom to be un-' derstood with one embodiment of my invention applied thereto, the indicating or signaling device being in normal position.

I have shown my invention applied to an automatic loom of the Northrop type, such as forms the subjectmatter of United States Patent No. 529,940, the stand A for the filling feeler or hopper being shown mounted on the breast-beam A The take-up roll T and the cloth-roll shaft Gr, having its journals 9 mounted in the upper ends of rack-bars g", which slide in slots in the stands F, secured as shown in the drawing.

ward end of the. lever being weighted at d to a overbalance the Weight of the indicator. The latter may conveniently be made of sheet metal and painted red or of some color which will attract attention. Normally the indicator is in the position shown in full lines, a stoppin 5 limiting its downward movement, the hopper-stand substantially hiding the indicator from View. A'latch e is fulcrumed at e on the standand is adapted to extend beneath the weight d and retain it in elevated position with the indicator in inoperative position. The latch has an attached forwardlyextended tail 6', pivotally connected with a de pending link 6 bent to clear the shield-like part A of the breast-beam and extending below it to a point considerably lower than the roll of cloth. The lower end of the link passes loosely through a hole 6 (see dotted lines) in a trip 6, fulcrumed at e on a bracket h, adjustably secured to one of the stands F by a clamp-bolt h, which passes through an upright elongated slot [L3 in the bracket. Nuts or collars 3 3, faston the link above and below the trip, connectthe latter with the link. of the trip is provided with a lateral lug 6, located in the path of movement of a releasing device, shown as a finger m, secured rigidly to the adjacent slide g above the trip. The weight of the link 6 is sufficient to maintain the latch e pressed upward against the weight d, with the lever d resting against the stop 5, As the diameter of the cloth wound upon the shaft G increases the rack-bars g gradually move downward, and when the finger at engages the lug e the trip 6 is rocked on its fulcrum, raising its outer end, and thereby lifting the link e Consequently the tail 6 is raised and the latch e depressed and moved out of engagement The inner end with the weight d, which immediately descends, elevating the indicator D into dottedline position in plain view of the weaver, above the filling-feeder. The weaver then knows that a out has been completed. If the cut is, say, forty yards, the trip a is set by means of the clamp-bolt 7L and bracket ii at such a distance below the releasing-finger m (when the cloth-roll shaft G is empty) that when forty yards of cloth have been wound up on said shaft G the indicator will be moved into indicating position. When a cut is begun, the weaver sets the indicator in inoperative or normal position and with the latch e beneath the weight.

By a device of this character the weaver is not required to pay close attention to the cloth to discover the cut-mark, and can devote his time and attention more completely to other matters.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loom, take-up mechanism, including a shaft on which the cloth is wound, a signal L or indicator, means cooperating therewith by which it is normally maintained in non-indicating position, and separate means to automatically and positively interrupt cooperation of said first-mentioned means and the signal or indicator, to thereby render the latter operative when a predetermined length of cloth has been wound upon said shaft.

2. In a loom, take-up mechanism, a visual indicator, means to retain it normally in nonindicating position, and means operative automatically when a predetermined length of cloth has been taken up to render inoperative the retaining means and thereby to effect movement of the indicator into a conspicuous position.

3. In a loom, take-up mechanism, a visual indicator, a device to move it into indicating position, means, including a latch, to. retain the indicator in non-indicating position, and a releasing-device for said means, governed by or through the take-up mechanism, to render the latch inoperative when a predetermined length of cloth has been taken up.

4. In a loom, take-up mechanism, including a shaft on which the clothis wound, sliding supports therefor, a pivotally-mounted indicator, a device to move it into indicating position, a latch to engage said device and retain the indicator in non-indicating position, a trip connected with the latch, and a releasing device for the trip, mounted on one ofthe sliding supports, to render the latch inoperative when a predetermined length of cloth has been wound on said shaft.

5. In a loom, take-up mechanism, including a shaft on which the cloth is Wound, sliding supports therefor, a pivotally-mounted indicator, a device to move it into indicating position, a latch to engage said device and retain the indicator in non-indicating position, a trip connected with the latch, means to ad just the trip for difierent lengths of out, and a releasing device for the trip, mounted on one of the sliding supports, to render the latch inoperative when a out has been wound on the shaft.

6. In an automatic loom provided with a stand for a'filling-feeder, a cut indicator pivotally mounted thereon and having an attached weight to move it into indicating position, a latch to engage the weight and retain the indicator in non-indicating position, takeup mechanism, and means to automatically retract the latch when a predetermined length of cloth, or out, has been taken up.

7. In a loom, take-up mechanism, a visual indicator, a device to move it into indicating position, means, including a latch and an adjustable trip connected therewith, to normally retain the indicator in non-indicating position, and a movable finger to engage the trip and release the indicator from control of the latch when a predetermined length of cloth has been woven.

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

WILLIAM HAYNES.
