TAKE-UP MECHANISM.

SPECIFICATION forming part of Letters Patent No. 595,103, dated December 7, 1897.

Application filed April 12, 1897. Serial No. 631,741. (N mOd L To all whom it may concern: tion of a driven shaft, which may be the Be it known that we, GEORGE F.

4 is removed. The operation of our take-up mechanism 50 In the accompanying drawings, 1 is a porwill be readily understood by those skilled in the art from the above description in connection with thedrawings.

When the shaft 1 revolves in the ordinary operation of the loom, the shell 4, fast thereon, will revolve with it and will carry the drum or take-up roll 7 and the hand-wheel 2 through the combination-gear 10, loosely mounted on the eccentric portion 3 of the hand-wheel 2. When it is desired to cause the take-up roll or drum 7 toturn in either direction independently of the shaft 1, said shaft continuing to revolve, the hand-wheel 2 is turned in one direction or the other, according to whether it is desired to turn the take-up roll or drum 7 forward or back. When the handwheel'2 is revolved in either direction, said hand-wheel being loose on the shaft 1, as above stated, the eccentric portion 3 thereon revolves within the concentric central opening in the combination-gear 10 and moves said gear so that the internal gear-teeth 12 will be engaged continually with the gear-teeth 9 on the shell 4 through any movement of the eccentric and hand-wheel, and it will be noticed that by one revolution of the hand-wheel 2 and the eccentric portion 3 thereon all the gear-teeth 9 have been engaged by the gearteeth 12, and if there are one or more gearteeth 12 than there are gear-teeth 9 the movement of the combination-gear 10 will be advanced beyond its original position by the difference in the number of teeth between teeth 9 and 12. An operation of a similar nature will take place between the gear-teeth 8 and the gear-teeth 11 during the same revolution of the hand-wheel, and there being more teeth 8 than there are teeth 11 they will be advanced or moved forward in the same direction around the teeth 11 as the teeth 12 are advanced around the teeth 9, and the movement of the take-up roll or drum 7 independently of the shaft 1 for one revolution of the handwheel 2 and eccentric-hub 3 thereon will be equal to the combined advancement of the gears 12 and 8, above referred to. The continued revolution of the hand-Wheel 2 will cause the take-up roll or drum 7 to revolve on the shaft 1 as desired.

The advantages of our take-up mechanism will be readily appreciated by those skilled in the art.

When any force is applied to rotate the take-up roll or drum 7 on the shaft 1 without the aid of the hand-wheel 2 by reason of the multiplying power of said hand-wheel and by reason of the eccentric portion 3 thereon, the

drum 7 will remain positively in any position given to it by the hand-wheel, so that there will be no backward or forward movement.

It willbe understood that the details of construction of our take-up mechanism may be varied somewhat from what is shown and described.

We have described our take-up mechanism with special reference to its use as a take-up for the take-up roll or drum on a narrow-ware loom; but we do not limit ourselves to this application of our mechanism, as it may be used for any other purpose and may be adapted to be applied to different machines or mechanical structures.

, Having thus described our invention,wl1at we claim as new, and desire to secure by Letters Patent, is

1. A take-up mechanism for l0oms,&c.,co1nprising a metal shell to be secured on a shaft, the periphery of the shell having an opening therein for access to the bolt, which secures the hub of the shell on the shaft, and external gear-teeth on said hub, a drum or takeup roll mounted loosely on the periphery of said shell, and having internal gear-teeth on the edge thereof, a gear-rim extendingloosely Within said gear-teeth, and provided with external gear-teeth meshing therewith, and internal gear-teeth meshing with the teeth on the shell, and a hand-wheel having an eccentric hub or portion which extends within the central opening in the gear-rim, which opening is concentric with the gear-teeth on said rim, substantially as shown and described.

2. A take-up mechanism for looms, &c.,comprising a metal shell to be secured on ashaft, and having external gear-teeth on its hub, a drum or take-up roll mounted loosely on the periphery of said shell, and having internal gear-teeth on the edge thereof, a gear-rim extending loosely within said gear-teeth, and provided with external gear-teeth meshing therewith, and internal gear-teeth meshing with the teeth on the shell, and a hand-wheel having an eccentric hub or portion which extends within the central opening in the gearrim,which opening is concentric with the gearteeth on said rim, substantially as shown and described.
