TAKE-UP FO R KNITTING-MAGHINES.

SPECIFICATION forming part of Letters Patent No, 345,130, dated July 6, 1886.

Serial No. 177,535. (No model.)

To all whom itmay concern.-

Be it known thatI, EDWARD H. GODSLIALK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful ImprovementinTake-Ups forKnitting-lvlachines, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 represents a side elevation of the rotary head ofa knitting-machine with operating mechanism, in connection with a takenp device for the same embodying my invention. Fig. 2 represents a partial vertical section and partial side elevation thereof at a right angle to Fig. 1. Fig. 3 represents a central longitudinal section of one of the feedrollers thereof and adjacent portions on an enlarged scale. Figs. Land 5 represent perspective views of detached portions thereof. Fig. 6 represents a perspective view of a portion of the roller shown in Fig. 3. Fig. 7 represents an end view of the parts shown in Fig. 8. Fig. 8 represents a partial side elevation and partial longitudinal section of the winding-roller with supporting-shaft,and frictional clutch mechanism connecting said shaft and roller.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of means for causing a fabric to be drawn from a knittingmachine and wound with a uniform speed and tension, avoiding improper stretching or breaking of the goods, injury to the machinery,'&c., as will be hereinafter set forth.

Referring to the drawings, A represents the rotary head of aknitting-machine, and B represents a pinion which meshes with a gearwheel or toothed rim, 0, on the said head, the said pinion B being connected by bevel-gearing to a driving-shaft, which receives motion by means of a pulley operated by power from any suitable source, all as well known, and forming no part of the present invention.

Connected with the rotary head or cylinder of the machine is a frame, D, which depends therefrom and carries at its lower end a shaft, E, to which is secured a pinion, F, the latter meshing with a toothed wheel, G, which is mounted on the base H and prevented from rotation thereon. TheshaftE has also secured to it a worm, J, which meshes with a wormwheel, K, the shaft whereof carries a pinion, L, which imparts motion to a gear-wheel, L, and consequently to gear-wheels L L.

To the shaft M of the pinion L is secured a winding drum or roller, M, and to that of the pinion or gear-wheel L is secured a feed-roller, N, above which roller is a feed-roller, P, it being noticed that the shafts of said drum and rollers are mounted on the frame D.

then the machine is set in motion,the pinion F is carried around with the frame D, which, as has been stated, is connected with the machine, and as said pinion meshes with the wheel G, and rotates around the same, motion is imparted to the worm and worm-wheel J K and earin L L L L and conse uentlv to the rollersN Paud winding-drum M, whereby the fabric knitted by the machine may be wound on the drum, it being drawn forward and guided thereto by the rollers N P.

It is important to adjust the feed-rollers so that the fabric is fed at the proper speed to the drum. For this purpose the roller N is made expansible and formed of segments N, (see Fig. 6,) which are grooved circumferentially to receive rubber bands Q, so that the segments are properly held together, said bands expanding and contracting in accordance with the adjustment of the segments. The roller is hollow and has wedge-shaped shoulders N on its inner peripheries of its segment, against which bear cone shaped blocks R, the latter being secured to a sleeve, It, which is fitted on the shaft N of the roller. The ends of the roller are grooved radially, the grooves N freely receiving radial tongues S on the inner faces of caps S, which are rested against said ends, it being seen that the shaft passes through one of the caps S, and the shaft and sleeve pass through the opposite cap. The outer end of the shaft carries an arm, T, to which is swiveled a screw, U, the latter engaging with an arm, V, on the outer end of the sleeve It, and the point of the screw being sustained in the adjacent cap S. It will be seen that by rotating the screw U the sleeve R, and consequently the blocks B, may be moved out or in to cause the segments to expand or contract, and thus the diameter of the roller may be adjusted with nicety for imparting proper speed to the knitted fabric in its passage to the winding-drum, assisting in preserving the tension of said fabric.

Inorder to adapt the drum M so that should there be any strain on the fabric the same may be relieved, said drum is mounted loosely on its shaft M, the latter carrying near one end a friction-disk, W, which is held between friction-plates X, the latter being loosely mounted 011 the shaft M and clamped together by bolts X", one of said plates carrying a screw or bolt, Y, which engages with a cap, Z, the latter being screwed or otherwise secured to the end of the drum, and freely encircling the shaft M. It will be seen that when the shaft is rotated its power is communicated to the disk \V, and thence by the plates X, screw Y, and cap Z to the drum. Suitable washers are interposed between the disk \V and plates X to hold the parts sufficiently firm, so that they move as one, the friction being adjusted by the bolts'X. It is evident that should there be any strain on the fabric while it is being wound on the drum, so that it resists winding, the plates X will slip on tLe disk W, although the shaft M continues its rotation, and thus the winding is prevented until the strain is relieved. By this construction the fabric is prevented from being stretched or broken and the machinery injured, and the fabric is wound with a uniform tension on the drum.

" The wheel G is held on the base by a frictionrim, G, and may be raised by a lever or trcadlc, t", which engages with the shaft of said wheel.

Having thus described myinvcntion, what I clai m as new, and desire to secure by Letters Patent, is-

1. in a rotary knitting-machine, the base A, having the pending frame I) connected therewith, in combination with the feed and guide roller N.journaled in bearings in the said frame 1), mechanism, substantially as described, for imparting rotary motion to said roller N, and means, substantially as described, for adjusting the diameter of said roller N, all substantiall y as and for the purpose set forth.

2. .A rotary knitting-machine having a guide and feed roller adjustable in diameter, and a winding-drum with frictional clutch attachments, and means, substantially as described, for operating said parts, said feedroller and winding-drum being jonrnaled in a frame pending from the said rotary head of said knitting-machine, substantially as described.
