PATENT CFFICE.

HENRY HEBERT, OF FALL RIVER, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY, OF HOPEDALE, MASSACHUSETTS, A COR- PORATION OF MAINE.

SPECIFICATION forming part of Letters Patent No. 737,405, dated August 125, 1903.

Application filed July 12; 1902. Serial No. 115,294. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, HENRY HEBERT, a citizen of the United States, and a resident of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Measuring Mechanism for Warpers, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of a simple and efiicient measuring mechanism particularly adapted for use in connection with warping-machines whereby the same can be automatically stopped when a predetermined length of yarn has been wound upon the beam. Devices of this general type have been heretofore constructed wherein the motive power has been derived from the measuring-roll or from the windingdrum by or through which the beam is rotated, and herein I have shown my invention as relating to the former class, the motion of the measuring mechanism being derived from the measuring-roll.

The various novel features of my invention will be hereinafter described, and particularly pointed out in the following claims.

Figure l is an end elevation of a warpingmachine of usual construction with one embodiment of my inventian applied thereto; and Fig. 2 is a sectional detail on the line 2 2, Fig. l.

Referring to Fig. 1, the winding-drum D, the beam B10, on which the yarn zo is wound, the measuring-roll M, detectors D10 to arrest a normally vibrating feeler (not shown) upon breakage of a warp-thread, the rock-shaft a', on which the feeler is mounted, and the depending arm a, fast on the rock-shaft and vibrating as the shaft is rocked in usual man ner, maybe and are all of well-known or usual construction. The belt is shipped by or through the turning of a rock-shaft b3, havrocker-arm b5, a shipper-rod 227 being connected at b to the rocker-arm and being upturned and extended through a holding-plate bx, a

shoulder bs engaging the under side of the 624,541, dated May 9, 1899;

lng an attached starting-treadle B and a" plate and maintaining the stop-motion inoperative when the machine is running, substantially as in United States Patent No.

So, too, the upturned rocker-arm d4, having the pivotallymounted latch d8, with its upturned arm d10 in the path of the pin ax and provided with a toe d to enter between the shipper-rod and the knock-off lever b9 when the machine is to be stopped automatically, and the lug 610 of the knock-od lever may be substantially as in said patent, the rotation of the drum D acting, through the cam d and follower-arm d2, to rock or vibrate the arm di. When the machine is running properly, the vibrating arm a prevents the toe d9 from cooperating with the knock-0E lever; but a released detector acts to stop the rotation of the rock-shaft c'.

The latch d8 rocks, and the toe engages the knock-off lever, so that on the swing of the arm d4 to the left, Fig. 1, the lug b1 will act upon the shipper-rod 197 and release it from its holding-plate to thereby stop the machine, all in well-known manner.

I will now describe the measuring mechanism.

The journal m of the measuring-roll M has secured to it a worm m in mesh with a wormgear m2, fast on a horizontal shaft m3, rotatably mounted in bearings mx on the warperframe, said shaft having a worm m4 formed thereon in mesh with a peripheral worm-gear m5 on a disk M. The latter is provided with .a circularl -arran ed series of holes m an one of which is adapted to receive a releas ing or tripping pin m7, and in order that I may readily disengage the worm m4 and gear m5 I have rotatably mounted the disk M on an eccentric hub m8 (see Fig. 2) on a stud lm9,moun ted in a suitable bracket m1,secured to the main frame. A handle m12 is attached to the outer end of the stud, and by turning the latter the eccentric hub m8 will act to raise or lower the disk M', so that when raised out of operative engagement with the worm m4 the disk can be turned in either direction by hand. In Fig. l the arrows 20 and 30 indicate, respectively, the direction of rotation of the measuring-roll and the disk M. A

bracket N on the frame has a guide 15 for an upright headed slide-rod nx, provided with a collar fn and having its lower end guided by a 'guide 16 on the main frame, the lower end of the slide-rod being normally held out of the path of a lug ctw on the vibrating arm a, by or through a detent n2, slidably mounted in guides 22 on an arm n of the bracket N, a spring s, Fig. l, acting to maintain one end of the detent in position beneath the collar n. The opposite end of the detent is downturned at n3 in the path 0f movement of the pin\`ii? so that when the rotation of the disk M brings the pin into engagement with the part 'n3 of the detent the latter will be drawn out from beneath the collar n. The slide-rod nx immediately descends into the path of the lug d10, stopping the vibration of the arm a, and thereby effecting the operation of the stop-motion mechanism for the machine, as has been described, the slide-rod acting as a stop for the arm ct. Now by adopting a certain number of teeth for the gears m2 and m5 and the worm m4 and providing for, say, one revolution of the worm m/ to move the gear m2 ahead one tooth it will be manifest that the series of holes m6 can be so numbered and arranged as to indicate a certain number of yards of warp wound for each hole. Then y adopting a starting or zero point on the disk M and putting the pin m7 in the proper hole (corresponding to the desired number of yards to be wound) if the disk be set at the starting-point and the machine set in operation the rotation of the disk will gradually move the pin m7 toward the depending end n3 of the detent. When the desired number of yards have been wound upon the beam, the pin retracts the detent, and the machine is stopped automatically.

The mechanism is simple, eective, and durable. It can be readily set to the desired number of yards to be wound, and will not easily get out of order. To reset the slide-rod fax, the operative lifts it after setting the disk or dial M', and the detent n2 clicks past the collar n.

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

l. In aWarping-machine, a measuring-roll, measuring mechanism for the warp, actuating means therefor operated by the measuring-roll, and stopping means for the machine, including a normally vibrating member, the measuring mechanism including a stop, a detent to maintain it out of the path of movement of said member, and adjustable means to render the detent inoperative and thereby release the stop when a predetermined length of yarn has been wound.

2. In awarpingmachine, stopping means, warp-measuring mechanism to effect the operation of said means when a predetermined length of warp has been wound, said means including a detent, a disk having a pinto engage the detent and also provided with a gear, a driving-worm to actuate said gear, and thereby rotate the disk, and means to disengage the gear and worm to permit manualrotation of the disk to set the same, said means comprising a rotatable stud having an eccentric hub on which the disk is rotatably mounted, combined with means to actuate the driving-worm, rotative movement of the stud moving the disk Iand its gear toward or away from the driving-worm.

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

HENRY HEBERT.
