TAKE-UP MECHANISM FOR LOOMS.

Specification of Letters Patent.

Application filed May 26, 1910. Serial No. 563,485.

Patented Jan. 24, 1911.

To all whom it may concern:

1 Be it known that I, ALoNzo E. RHoAons, a citizen of the United States, and resident of I-Iopedale, county of WVorcester, State of Massachusetts, have invented an Improvement in Take-Up Mechanism for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to loom take-up mechanism .more particularly of the type wherein the driving member is rotated continuously and positively while the loom is in operation, and my present invention has for its object the production of novel means whereby the take-up roll can be disconnected at will from the actuating mechanism and turned forward or backward, manually, and herein take-up is arrested automatically when a certain change is effected in the normal operation of the loom,

' such for instance as a change of filling.

C of the loom has fast upon it a bevel gear 1 meshing with a bevel pinion 2 fast on an intermediate shaft 3 mounted in suitable bearings on the inside of the side frame A of the loom, the lower end of said shaft having a bevel pinion 4 which meshes with and drives a bevel gear 5. Said gear 5, and a like gear 6, areboth fast on a counter-shaft 7 carried in suitable bearings provided by a bracket 8 bolted to the loom side, the shaft 7 being parallel to the cam-shaft C but below and behind it and out of the way of other parts of the loom structure. The bevel gear 6 is at the outer side of the loom frame, as

, shown in Fig. 1, and meshes with a bevel pinion 9 fast on the lower end of a transmitting shaft 10 mounted in bearings 11, 12 on the loom side, and it will be observed that this shaft is rotated continuously while the loom 1s in o eration. A worm 13 loose on the shaft a jacent the bearing 12, and a collar 14 rotatable with and longitudinally movable on the shaft, constitute a clutch device, one of its parts, as 14, having a projection 15 to enter a notch 16 in the other part or worm 13 and effect rotation of the latter with said shaft when the clutch device is operative, as it is illustrated in Fig. l. The clutch members are held in engagement by a suitable spring 17 interposed between the member 1 1 and a collar 18 fast on the front end of the transmitting shaft. The clutch is opened or released to disconnect the shaft and worm by means of a yoke 19 forming one arm of a bell-crank pivoted at 20 on the loom side, the other and forwardly extended arm 21 of the bell-crank having a notched portion 22 loosely entering a longitudinal slot 23, Fig. 2, in the lower end of a link 24.

Herein I have shown my invention as applied to a loom adapted to effect automatically a change of filling, as in United States Patent No. 529,940 granted November 27, 1894 to Northrop, and in Figs. 1 and 2 the starting or controlling rock-shaft D when turned in the direction of arrow 100 places in operation the filling-changing mechanism, as in said patent. Said rock-shaft has an upturned arm d fast thereon arranged to be swung outward by the usual fork-slide (not shown) when filling failure is detected, to thereby turn the rockshaft D in the direction indicated by the arrow 100, Fig. 1. The upper end of link 21 is pivotally attached to a rearwardly extended arm (8 fast on shaft D, so that when the latter is turned to effect a replenishment of filling the link will be lifted, to swing the bell-crank and through its yoke-arm 19 separate the clutch members before referred to, so that while the transmitting shaft 10 continues to revolve the worm 13 will remain quiescent until the link 24 is lowered. As the Worm drives the take-up roll the latter will be arrested whenever the worm is thus disconnected from the transmitting shaft, as will be manifest. This temporary arrest of takeup, which is efi'ected automatically,

' nism.

prevents the formation of a thin place or streak in the cloth when a change of filling is called for. V

The take-up roll 25 mounted in usual bearings below the breast-beam B has an attached gear 26 meshing with a gear 27 driven by a pinion 28, the latter having an attached and larger pinion 29 meshing with a pinion 30 secured to or forming part of a gear 31, this train of gearing transmitting motion to the take-up roll from a shiftable gear 32. This shiftable gear is rotatable on a fixed shaft 33 mounted between the loom side A and the usual guide E for the clothroll, the said gear having an annularlygrooved hub 34 which is engaged by the inturned studs 35, Fig. 3, of a yoke-like gear shifter 36 having a hub at its lower end fulcrumed on a pintle 37 carried by a bifurcated bracket 38 fixedly attached to a part of the loom frame, such as the crossgirth F. As the pintle is at right angles to shaft 33 the gear shifter swings toward and from the adjacent loom side, and when swung to the left, Fig. 1, said gear shifter slides the shiftable gear 32 to the left and out of mesh with the gear 31 of the transmitting train of gearing just referred to. This movement of the shiftable gear is effected by the weaver, the gear-shifter 36 having an attached handle 39 provided for the purpose, and return movement is effected by a spring 40 fixed at one end to bracket 38 and secured at its other end to the gear shifter, as clearly shown in Fig. 3. A shaft 41 having at its outer end a hand-wheel 42 is carried by a bearing 43 on a fixed stand 44, and the inner end of this shaft has fixed on it a pinion 45, see dotted lines Fig. 1, which is always in mesh with the gear 31 of the transmitting train. hen it is desired to turn the take-up roll 25 either forward or backward the weaver shifts the gear 32, as described, thereby releasing the transmitting train from the other portion of the mechanism, and by means of the handwheel 42 the weaver can manipulate the take-up roll as may be necessary, whether the actuating worm 13 is in motion or at rest, and without being obliged to handle any greasy or oiled portions of the mecha- The shiftable gear 32 is always in mesh with a wide faced pinion 46, fast on the inner end of a shaft 47 extended through the stand 44 and having fast on its outer end a worm gear 48 which is in continuous mesh with the driving worm 13, as clearly shown in Fig. 1.

It will now be clear that whenever the driving member or worm is connected with the shaft 10 by the clutch device it will be revolved, and through worm-gear 48, pinion 46 and shiftable gear 32, the transmitting train of gearing will be actuated to rotate the take-up roll 25, the hand-wheel 42 revolving whenever said train is operating.

When a change of filling is effected the worm 13 is unclutched automatically from the shaft 10 and take-up is thereby arrested until the rock-shaft D causes the worm to be again clutched to the shaft 10 to rotate therewith.

Ordinarily there is no necessity to advance or let back the takeup roll when the loom is in motion, but it will be seen that were it not for the manually shiftable gear 32 it would be impossible for the weaver to move the take-up roll by hand without first unclutching the worm 13. By the manually operated shifting device, however, the takeup roll can be readily manipulated by hand, whether or not the worm is unclutched, for when the gear 32 is shifted by the weaver the transmitting train leading to the take-up roll is wholly disconnected from the parts immediately driven by the worm, to wit, the worm-gear 48 and the long pinion 46. The gear-shifter handle 39 and the manually controlled member 42 for operating the take-up roll by hand are within easy reach of the weaver. Should the Weaver fail to bring the shiftable gear into mesh with the train of gearing the spring 40 will act to slide the gear 32 into mesh with the gear 31 just as soon as the teeth of one come opposite spaces between teeth of the other, the gear 32 always revolving at a very slow speed when the loom is in motion.

Various changes or modifications in details of construction and arrangement may be made by those skilled in the art without departing from the spirit and scope of my invention as set forth in the claims annexed hereto.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a loom, a take-up roll and a train of transmitting gearing permanently connected therewith, manually-operated driving means for said train comprising a shaft having a pinion on its inner end, in continuous mesh wit-h a member of said train, and a hand wheel on the outer end of said shaft, and power actuatingmechanism for the train, including a driving member normally in continuous rotation, and a shiftable gear 'movable into and out of control of said train of gearing, said manually operated driving means being wholly independent of and separate from the power actuating-mechanism, combined with manually operated means to shift said gear and release the train from control thereby, and mechanism to effect antomatically temporary stoppage of the driving member to thereby arrest take-up.

2. In a loom, a shaft continuously rotated by a going part of the loom, a worm on said shaft, a clutch device to connect said worm and shaft to rotate in unison, means acting through the clutch to release the worm from the shaft automatically, a take-up roll, operthe latter is released from control by the 10 ating connections between it and the worm, worm. including a shiftable gear always under the In testimony whereof, I have signed my control of the worm, means to shift said gear name to this specification, in the presence of 5 manually to thereby release the take-up roll two subscribing witnesses;
