T @ZZ whom it may concern: gage the tail m2 of' the fork fo move the slide Be it known that l, ORREN A.

For this reason, provided for in said patent. and it may be also due in partto other causes, The fork-slide m is herein shown as prothe newly-made cloth will continue to stickA vided with two upturned ears m5 m7, and on to the take-up roll as it passes between it the former, which is nearer the outer end o f 7o 2o and the cloth-roll instead of being wound the slide, is mounted a lever c, a stud 5 proupon the latter, and the cloth is carried jecting laterally7 from said ear over the side around indefinitely upon the take up roll of the guide m@ Fig. 3.

(operative position,) Fig. l, a stop-lug s2 on Figure l is a transversesectional view of a the lower end of the arm at such time engagportion of a loom taken between the clothing the loom-frame and holding the signal or roll supports, showing the take-up mechanism indicator in abnormal extended position at th and with one embodiment of the present infront of the loom. 9o 4o vention applied thereto. Fig. 2 is a front Referring to Figs. 1 and 3, the ear m7 has elevation of the mechanism shown in Fig. l; a pin 7 loosely extended transversely through and Fig. 3 is a top or plan view of a portion it, and on the inner side 0f the ear said pin of the breast-beam, filling-detecting inechanhas fast upon it a lever f, downwardly exism, and holding-plate for the shipper, the tended outside the guide m to form a feeler 95 signaling device and the means for effecting fX, having a broadened foot f to rest upon its operation being shown in plan. the cloth substantially directly above the axis The take-up ratchet CL3, actuating-pawl a2, of the take-up roll. Beyond the feeler the the take-up or sand roll T, the cloth-roll TX, lever f is shown as longitudinally slotted at Figs. l and 2, the lling-fork mX its slide m, 8 to receive a pin 9 on the rear end of lever 1o@ 5o mounted in a guide m on the breast-beam, e, the normal position 0f the levers being the weft-hammer W, having a hook in to enclearly shown in Fig. 1, the feeler contacting with the cloth. At the outer side of ear m7 the pin 7 has secured to it an elongated finger f2, extended toward the back of the loom and above the filling-fork, tlie'free end of the finger being shown in Fig. l as downturned at f3 and normally held slightly above the head of the fork in front of its fulcrum by the weight of the feeler fx and its lever or carrier f. Now if the cloth sticks to the takeup roll'T and is carried around upon it the succeeding layers beneath will raise the cloth C as it passes to said roll, thereby lifting the feeler and rocking the pin 7 to depress the finger]2 until its downturned end f3 engages the fork-head and holds the tail m2 down to be engaged by the weft-ham mer hook VVw. At the same time the foot e2 of the actuator e' is depressed into position behind the head s' of the signal or indicator s, and as the slide m is moved outward by the weft-hammer the actuator will engage the signal and release it from the spring-clip 3X, so that it will fall by gravity into signaling position. (See dotted lines, Fig. l.) At the same time the slide m engages the knock-oft lever n and releases the shipper N to effect stoppage of the loom.

The 'foot e2 extends in front of the outer end of the fork-slide, so that a positive outward movement is imparted to the actuator to effect the operation of the signal or indicator. Should the fork detect absence of filling in usual manner, the outward movement of the slide will effect the release of the shipper, as described, but as the foot e2 of the actuator will be above the head s of the signal the latter will not be thrown into signaling position. The weaver will thus know that the loom stopped from some cause other than winding up of the cloth on the take-up roll.

The invention i's not restricted to the-pre cise construction and arrangement shown and described, as the same may be modified in various particulars Without departing from the spirit and scope of the invention.

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

l. In a loom, a cloth-roll, a take-up roll to eiect the winding of the cloth thereupon, and an indicator operated automatically upon accumulation of the cloth upon the take-up roll.

2. In a loom, a cloth-roll, a take-up roll to edect the winding of the cloth thereupon, a visual indicator, and means operated automatically upon winding of the cloth upon the take-up roll to move the indicator into abnormal position. y

3. In a loom, a cloth-roll, a take-up roll to elect the winding ot` the cloth thereupon, an indicator, a device to hold it in non-indicating posit-ion, and means operated by or through accumulation of cloth upon the take-up roll to release said indicator and elect its movenient into indicating position.

4. In a loom, a shipper to operate a stopping instrumentality, a holding device to retain the shipper in running position, take-up mechanism, including a take-up roll, and means operated automatically upon accumulation of cloth upon said roll to cause release of the shipper from its holding device.

5. In a loom, a shipper to operate a stopping instrumentality, a holding device to retain the shipper in running position, take-up mechanism, including a take-up roll, a visual indicator,means operated automatically upon accumulation of cloth upon said roll to cause release of the shipper from its holding device, and an actuator operated by said means to move the indicatorinto abnormal,indicat ing position. Y

6. In a loom, a shipper to operate a stoppinginstrumentality,illingdetecting means, including a slide, a shipper-releasing device operated by the slide upon detection of absence of filling, take-up mechanism, including a take-np roll, means operated by accumulationy of cloth on said roll to cause the actuation of said slide, an indicator, and actuating connections between it and the slide, rendered operative when the movement of the latter is due to cloth accumulation.

7. In a loom, a shipper to operate a stopping instrumentality, means to release the shipper upon detection of filling failure, take-up mechanism, including a take-up roll, means dependent upon an accumulation of cloth thereupon to cause release of the shipper, and an indicator moved automatically into indicating position upon release of the shipper by said latter means.

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

ORREN A. SAVYER.
