KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS LINT CLEARERFOR FILLING sror MOTIONS Application filed March 24, 1928. Serial No. 284,403.

This invention relates to improvementsin devices for insuring proper operation of filling stop motions by removing therefrom any lint which maycollect during the operation of the loom.

In certainfilling stop motions, particularly those on broad looms where the forkis located at the center of-the loo1n,-thelay is provided with a well or-depressioninto which the tines of the filling fork pass when weft is absent. When weft is present the fork-is held up and is prevented from moving into the well at that point in the'beatup of the lay where indicationto stop because of weft failure may occur. Whenweaving with certain kinds of yarn itis found that lint collects in the well and supports the fork, having the effect of permitting continuedoperation of the loom even though the weftbe absent, because of the fact that the fork is not permitted 'to drop into the well. It is an important object-of my present invention to provide means for clearing the well of such lint-as may collect and thereby insure proper operation of the stop motion. 7

One form of center filling stop motion which has gone into general use employs .a fixed bracket extending rearwardly from the breast beam and having a cam face along which moves a portion of the stop motion mechanism which-ismounted on the lay. It is a further object of my present invention to mount a clearing device on the'lay to be moved back and forth with the latter and to derive its motion partly from structure carried by the bracket.

In one forminy invention. employsa' hooked member which movesback and forth in the well of the filling stop motion in -a direction transverse of the lay so as to draw line forwardly. It is a furtherobjectof my invention to associate with the hooked member retaining deviceslocated in the well and operative to prevent movement of the lint to the rear part of the well after it has been moved forwardly by the hooked member.

WVitlrthese-and other objects in view which will appear as thedescription proceeds, my invention resides in (the combination and arrangement of parts hereinafter described and set forth in the claims. 1 V

In the accompanying drawings, wherein I have shown a convenient embodiment of my invention,

Fig. 1 is avertical section through a portion of the loom showing a filling stop motion having my invention applied thereto,

Fig. 3 is a detailed vertical section on line 33 of Fig. 2 showing the manner. of operating my invention, and j 'Fig. Al is a detailed vertical section online Referring to the drawings, I have shown; i

a 100m frame 10 and a lay 11 tobe moved toward and from the frame each beat of the loom. Secured to the breastbeam 10 of the loom frame is a bracket 12 havinga lever 13 pivoted thereto as at 14. By means of mech- I anism not shown the lever is held normally inthe position shown in Fig; 1. An adjustable cam plate 15 is held by a bolt 16-to the bracket and is-so placed as to expose the up per rearendof the lever 13 as clearly shown in Fig. 1. I I i The lay is provided with a bracket 17'to' which is pivoted as at 18 a dagger carrier 19 which supports the dagger 20. An upwardly extending link 21 pivotally connected at the lower end thereof to the carrier is attached at the upper end thereof to an arm 22 ofarocking fork member 23. Said member is provided with tines 24 which extendinto the well 25 in the'upper forward portion of the lay 11. The lay may be provided with the usual race plate 26 and may have a backstay 27 to position the reed 28.

'When the lay is in rear position the dagger 20 is held in raised position on the cam plate 15 and the effect of this is to raise the tines trainee 'MIASSACHUSETTS, A CORPORATION OF 24 to the dotted line position shown in to permit the dagger 20 to have direct engagementwith the lever 13. Continued forward movement of the lay will thereafter effect stoppage of the loom by mechanism not shown but set into action by the rocking of lever 13 around the axis 14.

I have shown hereinonly sufficient structureto indicate the manner in which my invention may be used and portions of the filling stop motion have been omitted for the sake of clearness. The matter thus far described forms no part ofmy present invention and ma be of the usual construction, references being made-to Patents Nos. 560,036 to Hutchins and 1,369,417 to Gagnon fora more complete disclosure of the structure and operation of the particular form of filling stop motion illustrated.

In carrying my present invention into effect Iqprovide means for clearing the well 25ofanylint which may accumulate therein. Accordingly, I provide a stud which ismounte'don bracket 17 to move with the lay and mount on said stud a lever 31 having an upwardly extended arm 32 located preferably in front of thelay. To the upper end of said arm 32 I pivot a plurality of clearing members 33 the rear of each of which is'formed with a hook 3 1. The members 33 lie below the member-24 so as not to interfere with the operation of said member or the upright link 21.

The lever 31 is provided with a rearwardly extending arm 35 which extends through an eye 36 formed as part of the bracket 12 as shown more clearly in Fig. 4. The rear end of the arm 35 is weighted as at 37 if desired, although I may dispense with the weight in view of the fact that the end 35 extends through the closed eye 36 and is therefore given positive motions in opposite d1- rections.- i

The hooked'members 33 normally lie in thebottom of the well in the position shown in full lines in Fig. 3 when the lay is in its rearward position, or in the position shown in dotted lines in Fig. 1. As the lay moves forwardly its position will change with respect to the eye member 36 and the rearwardly extending arm' 35 of the lever 31 will be raised relatively to the stud 30 to produce aleft hand movement as viewed in Fig. 1 on the part of lever 31 around its supporting stud. The effect of this is to move the upright arm 32 forwardly to move the hooks from the position: shown in Fig. 3 to the position shown in full lines in Fig.1. Said hooks are therefore effective to carry forwardly any mass of lint-L such as that indicated in Fig.3.

In order to retainthe lint or other accu-" tween and on the sides of the hooked members These peg members operate to prevent the lint from moving rearwardly when the hooked members 33 moveback into the well upon rearward movement of the lay.

Asshown in Fig. 3 there is an open space below the member 23 defined bythe ears l1 and 42 which afford pivotal support for said member 23 and are mountedon the lay. In this way there is provided a suitable discharge opening at the forward endof the well 25 for removal of the lint.

Frointlie foregoing it will be seen that I haveprovided a very simple device which is movable back and forth in the well 25 to engage any lint or other accumulation which maycollect in said well. It will further be seen that the movement of the lint removing element is effected by the forwardand backward movement of the lay and that said hooked members are in forward position where they cannot interfere with theoperation of the filling fork at. that time in the cycle of It will also be seen that the .peg members extending upwardly from, the bottom of the:

well act not only to retain the-lint but also because of the fact that theyare .incllned forwardlyaid in the discharge of the lint the loom when the filling fork will move 'downwardly in its, normal operation Furthermore, itwill be noted. that the sup-. 1

23. is provided withan .opening which the lint may pass; v
