JOHN O. MCKEAN, OF WESTFIELD, MASSACHUSETTS, .ASSIG-NOR TO FOSTER MACHINE COMPANY, OF WESTFIELD, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS STOP MOTION FOR WINDING TMACHINES.
Specification of Letters Patent.
Patented Feb. 14, 1922.
Application filed March 19, 1921. Serial No. 453,591.
' the latch actuating shaft until the threads get under sufiicient headway to hold the drops out of the path of the teeth on the said latch actuating shaft.
The stop motion herein shown and described is like the one illustrated in my Letters Patent No. 1,018,920, dated February 27, 1912, except in that the latch actuating shaft. in this present invention, rotates instead of oscillates, and in that the shape of the latch, in the present invention, is changed whereby the latch lever may be manipu-- lated to coact withthe latch for holding the drops temporarily out ofthe path of the teeth on the latchactuating shaft.
In the accompanying drawings:
F 1 represents a vertical transverse section through so much of a winding machine as will give a clear understanding of my invention; the parts being in the positions which they assume under normal running conditions.
Fig. 2 represents a similar view with the drops held temporarilyout of the path of the teeth on 'thelatch actuating shaft until the threads get under sufficient headway to of themselves hold the dropsout of the path of the said teeth. The rotating cam shaft is denoted by 1 and its usual thread guide actuating cam by 2. The continuously rotating cop winding drum is denoted by 3 and its shaft by 4%. A pair of uprights 5, which serve as a mounting for the drum shaft 4, are carried by the cross bar 6. The cop is denoted by '7 and its rocking holder by 8. A spring 9 tends to hold the cop 7 againstits winding drum 3.
I will describe certain of the parts of the stop motion only necessary for a clear understanding of my improvements thereon, it being understood that the other parts of the stop motion work in the well-known manner, as described in my Letters Patent above referred to.
lhe plate-like arm 10 of the stop motion controlling latch lever is pivoted on the cross shaft 11 mounted in suitable bearings 111 the uprights nearthe cross bar 6. The cop holder 8 is supported in the usual man nor on the cross shaft 11. The arm 12 of the latch lever projects from the plate-like arm of the latch lever. A spring 13 interposed between the cross bar 6 and the arm 12 tends to swing the arm 12 downwardly when released, to set the stop motion. This arm 12 is provided'with a suitable handle 14. A bracket 15 is secured to the cross bar 6. Ears 16 depending from the cross bar 6 serve as bearings for a continuously rotating latch actuating shaft 17,
which shaft is provided with a sleeve 18 bearing a series of teeth 19. An uprising latch 20 is pivoted at 21 to the bracket 15 This latch is provided with a recess 22 having a right angle wall'23and an inclined wall 24. The upper end of this latch 20 projects beyond the body of the latch and the inclined wall 2 .2 extends along this overhanging portion. The arm 12 of the stop motion controlling latch lever is provided with a lug 25 which is arranged to be brought into and out of the recess 22 in the latch. 7 l
The drops (one only of which is shown herein) are denoted by 26, each of which drops is provided with an eye 27. at its outer end, the inner end of each drop being pivoted on a cross bar 28 supported by lugs 29 depending from a. plate-like extension 30 of the latch 20. Each drop is provided with an abutment 31 to limittheu'pward movement of the drop and an abutment 32 to limit the downward movement of thedrop. Each drop is also provided with an arm 33 which is arranged to be brought into and out of the path ofthe teeth 19 on the sleeve 18 of the rotary latch actuating shaft 17, according to the position of the drop and the latch; V
In operation, when one of the threads breaks it will permit the drop 26 to fall, thereby bringing its arm 33 in position to be engaged by one of the teeth 19, and by reason of this engagement, the latch 20 will be rocked rearwardly sufiieient to release the lug 25 of the latch lever arm 12 from its en gagement with the shoulder formed by the right angle wall 23 of the recess 22.
The spring 13 will then draw the arm downwardly to set the stop motion in the well-known manner, the specific description of which has not been made herein as it forms no part of this present invention. After the thread has been mended, the latch arm is lifted beyond its locking position, to release the stop motion and start the winding of the thread. The lug 25 on the latch lever will be caused to engage the portion of the inclined end wall 2st. on the overhanging end of the latch, preventing the latch from returning to its lockingposition. The operator may hold the latch lever in this position and thus hold the drops temporarily away from the teeth 19 of the latch actuating shaft until the threads get under suilicient headway to of, themselves hold the drops out of the path of the said teeth. The latch lever may then be released and the lug 25 will be guided inwardly along the inelinedwall2et into the recess 22and against the shoulder 23, as the latch returns to its original locking position.
Heretofore when the latch lever has been raised, the latch would be permitted to immediately swing back into its locking position with the latch lever, and if the threads had not reached sufiicient headway to of themselves hold the drops elevated, the drops would be brought into engagement with their latch actuating member. This invention obviates this feature as the engagement of the lug 2-5 with the inclined wall on the projectingfree end of the latch 20 prevents the latch from rocking back into its locking position with the latch lever until the operator intentionally releases the lever to permit this locking movement.
It is evident that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; and hence I do not intend to be limited to the details herein shown and described except as they may be specifically included in the claims, but
Vhat I claim is:
1. In astopmotion for winding machines, a stop motion controlling latch lever, a latch therefor, a drop, and a movable member arranged to engage the drop for moving the latch to release it from the lever to set the stop motion, said lever being manually movable into position to release the stop motion and prevent the full return of the latch, thereby temporarily holding the drop out of the path of said movable member until the thread itself reaches sufiicient headway to hold the drop out of said path, when the lever may be released to permit the full return of the latch to its locking engagement with the lever.
2. In a stop motion for winding machines, a stop motion controlling latch lever having a lug, a latch having a recess for receiving said lug, and a projection extending beyond said recess, a drop, and a movable member arranged to engage the drop for moving the latch to release it from the lever to set the stop motion, said lever being manually movable to bring its lug against said latch projection to release the stop motion and prevent the full return of the latch, thereby temporarily holding the drop out of the path of said movable member until the thread itself reaches sufficient headway to hold the drop out of said path, when the lever may be released to permit the full return of the latch to its locking engagement with the lever.
8. In a stop motion for winding machines, a stop motion controlling latch lever having a lug, a latch having a recess for receiving said lug, and a projection extend ing beyond said recess, said projection having an inclined wall, a drop, and a movable member arranged to engage the drop for moving the latch to release it from the lever to set the stopmotion, said lever being manually movable to bring its lug against said inclined wall to release the stop motion and prevent the full return of the latch, thereby temporarily holding the drop out of the path of said movable member until the thread itself reaches suflicient headway to hold the drop out of said path, when the lever may be released to permit the full return of the latch toitslocking engagement with the lever.
at. I11 astop motion for winding machines, astop motion controlling latch lever having aflug, a latch having a recess for receiving said lug tohold' the lever elevated, and a projection extending beyond said recess, and a latch actuating member arranged to swing the latch to release it from the lever to set, the stop motion, said lever being manually movable upwardly beyond its locking position to bring its lug against said latch projection to-release thestop motion and prevent the full return of. the latch. when the lever may be released to permit the full return of the latch towits locking engagement with the lever.
, In testimony, that I claim the foregoing as my invention, I have signed my name this 12th day of March 1921;
JOHN O. MoKEAN.
