YARN-CLEARER.

Specification of Letters Patent.

Application filed June 16, 1911.

Patented May 21, 1912.

Serial No. 633,506.

To all whom it may concern:

Be it known that I, CLARENCE N. Crimes, of Lowell, in the county of Middlesex and the Commonwealth of Massachusetts, have inevented a certain new and useful Improvement in Yarn-Glearers, of which the following description and claims, with the accompanying drawing, is a specification.

This invention is an improvement in that class of yarn clearers in which a movable slub-detector cooperates with a yarn-grip- It consists essentially in the said detector in trigger-engagement with the gripper.

It also consists in certain details of construction and in arrangements and combinations thereof with other parts.

In the drawing, which shows my invention only in its preferred form :-Figure 1, is a side-elevation; Fig. 2 is an end-elevation; Fig. 3 is a plan; Figs. 4 and 5 show the movable slub-detector in side-elevation and plan, respectively; Figs. (3 and 7 show the movable member of the yarn-gripper in side-elevation and plan, respectively.

In the description and claims the term slub will be employed to denote any enlargement of the yarn, such as a large knot, a double bunch of fiber incorporated therein or the like.

In the figures: 1 is the supporting-rod for a series of clearers; 2 is the supportingstand; 3 is the clamp for the stand; 4 is the stud, secured in the stand 2, upon which the slub-detector is pivotally mounted; 5 is the detector-block, to which the other I parts of the slub-detector are fastened; 6

is the yarn-gage, fastened to the block by the screw 7 and by the screw 8 for adjusting and holding the gage; 9 is the cam, integral with the block and carrying the triggers or stops 10 and 11 at its outer end for setting the movable jaw of the yarn-gripper; 12 is the movable jaw of the yarngripper, pivotally mounted upon the stud 13 secured in the stand 2, in trigger-engagement with the slub-detector through the detector-triggers 10 and 11 and the

grippertriggers

14 and 15, having a gripping-face 16, and carrying a weight 20 for automatically operating the jaw when the detector moves out of engagement therewith; 17 is the gripping-face of the stationary jaw of the yarn-gripper, the stationary jaw being integral with the stand 2; 18 is a yarnguiding stud fastened adjustably in the stand 2; 19 is the yarn, moving in the directions of the arrowheads thereon.

When the slub-detector is located as in Fig. 1, it can rotate through a part of a right-handed rotation but it is held almost at the limit of its left-handed rotation by the engagement of the triggers 10 and 14:. If the weight 20 is slightly raised, the detector will move to the limit of its lefthanded rotation and the block 5 will contact with the stand 2. The slub-detector is so counterweighted that it tends to make a left handed rotation as seen in Fig. 1. When the moving yarn carries a slub which cannot pass with suflicient freedom through the yarn-gage 6, the slubwill catch in the slit of the gage and the yarn-pull will quickly rotate the detector about the stud 1 until the trigger 10 shall contact with the jaw 12. As soon as the detector-triggers 10 and 11 have moved out of contact with the gripper-triggers 1 1 and 15, the weight 20 will fall, the trigger 10 will strike the jaw 12,

and the yarn will be held fast between the gripper-jaws 16 and 17 The slub-detector may be of one piece only or of many pieces. Either construction would be within my invention.

The movable gripping-jaw and its operating means may be of one piece only or of several pieces. Either construction would be within my invention.

The motion of the slub-detector or of the gripper-jaw may be rectilinear or otherwise, instead of circular, and be within my invention. The cam 9 and one of the triggers 10 or 11 can be omitted without departing from my invention.

I claim:

1. In combination an automatic yarngripper normally tending to grip the yarn, and a movable slub-detector, normally in trigger-engagement with the gripper while yarn without slubs is passing the detector but having slub-actuated means for releasing such trigger-engagement.

2. In combination a Weight-actuated yarn-gripper normally tending to grip the yarn, and a movable slub-detector, normally in trigger-engagement with the gripper while yarn without slubs is passing the detector but having slub-actuated means for releasing such trigger-engagement.

3. In combination a yarn-gripper having a movable jaw, and a movable Shlb-dBtGCtOl', and means for operating the jaw hen the comprising a movable detector-block; a detector moves out ofengagement therewith. 10 yarn-gage fastened to the block, and a cam In testimony whereof, I aflix my signaintegral With the block and having a trigture in the presence of tWo Witnesses.
