KNITTING-MACHINE TAKE-UP.

SPECIFICATION forming part of Letters Patent No. 784,567, dated March 14, 1905.

Application filed August 6, 1903. Serial No 168,393-

Be it known that I, LEON O. HUSE, a citizen of the United States, residing at Laconia, in the county of Bel knap and State of New Ham pshire, have invented an Improvement in Knitting-Machine Take-Ups, of which the follow ing description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

My invention is an improved take-up for knitting-machines and the like, its object being to provide means or enabling the operator to adjust or remove the knitted fabric from the take-up without stopping the machine.

I have applied my invention to the usual form of take-up, comprising a frame pivoted and preferably counterbalanced and carrying rolls and driving mechanisms therefor, between which the web or knitted article is automatically pulled with such tension as may be required, and instead of being obliged to stop the machine and turn back the take-up mechanism by hand, as has been the practice, I provide means for temporarily disconnecting the take-up rolls and their driving mechanism, so that the latter may not be interfered with in any way, and the rolls are free to move independently thereof, as required.

Further advantages of my invention will be set forth in connection with the following description of the constructional details thereof, reference being had to the accon'lpanying drawings, in which I have shown apreferred embodiment of my invention, and later will be more particularly defined in the appended claims.

In the drawings, Figure 1 is a fragmentary detail of the lower portion of a knitting-machine, showing in side elevation my invention applied thereto. Fig. 2 is a horizontal sectional view taken on the line 2 2', Fig. 1. Fig.

. 3 is an enlarged longitudinal sectional viewof one form of disconnecting device.

It will be understood that my invention is not restricted to any particular form of knit-v ting-machine or take-up mechanism; but for convenience of illustration I have shown a take-up comprising a frame a, pivoted at a" to a bracket (0 mounted on a standard a of a usual knitting-machine, the further details of which are not shown. Said frame a has an arm (1 extending outwardly and provided with a counterbalance-weight a, which regulates the tension or degree of pull of the take-up by counterbalancing more or less the weight 0f the mechanism carried at the other end of the frame. Adjacent its pivot the frame carries an upright portion a, in which is journaled a shaft (17, provided at one end with a driving-pulley a, driven by a belt a. from the driving mechanism of the upper portion of the knitting-machine, and at its other end said shaft (4 is provided with a worm a meshing with a worm-wheel a, fast on a shaft (4 journaled in a cross-bar a of the frame. The latter beyond said cross-bar has two separated parts a a in which are journaled a pair of take-up rolls a a, the latter being adjustable in ways a by means of adjusting-bolts (4 operating through the end of the frame against the journal-boxes of the roll a At one end said rolls are provided with similar intermeshing pinions a (1. and the roll {0 3i its opposite end has a gear (4 adapted to mesh with a pinion 0 splined on shaft a and free to be moved longitudinally bya handhold o connected thereto by a sleeve a while at its other end it is releasably locked in normal operative position by a spring a. engaging a grooved collar (1 secured to the inner side of said pinion a. This constitutes one form of coupling device for detachably connecting the take-u p with its driving mechanism.

In operation the take-up rolls a a are adjusted into proper engagement with the web 20 of knitted material, which is fed down from the knitting mechanism above, and the counterbalance-weight a is adjusted out or in to give the required tension according to the kind and quality of fabric being knitted. As the knitting progresses the driving mechanism through the belt a, pulley a, worm-gear a wheel a, and train of gears therefrom causes the work w to be taken up by the rolls as rapidly asitis knitted, the take-up mechanism swinging freely on its pivot a, according to the requirements of the work. If for any reason the work w requires to be slackened or removed from the take-up or tightened therein, the operator instead of stopping the mechanism simply lifts up on the spring a with one hand and pulls the pinion rfoutwardly with the other hand, thereby instantly disengaging said pinion from the gear 64 leaving the rolls a" a free to turn in any direction that the work 20 may be'pulled by the operator. If the fabric is to be slackened, the operator, having released the driving mechanism from engagement with the take-up rolls, simply pulls up slightly on the work until the proper slackness is secured. The rolls a (0 when disengaged from the pinion a may be turned freely in either direction, and by pulling on the work the latter may be withdrawn from the machine. The operator may reengage the driving mechanism with said rolls simply by pushing the pinion a back into place, where it is locked by the spring (0 I do not intend to restrict my invention to the particular embodiment thereof herein shown, inasmuch as it is readily applicable to various kinds of take-up and is capable of a wide variety of mechanical embodiments without departing from the spirit and scope of my invention.

If desired, (and in some instances the necessities of the work require it,) the weight a may be used at the opposite side of the fulcrum rt from that shown in the drawings, the loop of the weight entering a notch ta The weight will be used in the position shown by full lines where the yarn is tender and it is desired to counterbalance the weight of the take-up; but on larger machines using heavy yarns the weight will be sustained at the lefthand side of the fulcrum a close to where the work comes from the needle-cylinder, as represented by dotted lines.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. A take-up comprising a frame pivotally mounted, a pair of take-up rolls journaled in said frame, gears connecting said rolls, a crossbar carried by said frame, a shaft mounted in said cross-bar, means for driving said shaft, and a pinion mounted to rotate with said shaft, and movable longitudinally thereon to carry said pinion into and out of engagement with the said take-up rolls.

2. A take-up comprisinga pivotally-mounted frame, take-up rolls journaled therein, a driving-shaft therefor, a pinion normally in driving connection with said rolls and mounted to rotate with and be longitudinally movable on said shaft into and out of driving engagement with the take-up rolls, and means to rotate said shaft.

3. Atake-up comprising a pivotally-mounted frame, take-up rolls journaled therein, a driving-shaft therefor, a pinion normally in drivingcon nection with said rolls and mounted to rotate with and be longitudinally movable on said shaft into and out of engagement with the take-up rolls, locking means for holding the pinion in driving engagement with the rolls, and means to rotate said shaft.

4. A take-up comprising a frame pivotally mounted to swing upward and downward in a vertical plane, a pair of take-up rolls mounted in said frame, a cross-bar on said frame, a driving-shaft mounted in said cross-bar, a pinion 'splined to said shaft to be longitudinally movable thereon and rotatable therewith, to put the same into or out of driving connection with the take-up rolls, and means for rotating said shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
