6 Claims. .(Cl. 242-55) This application is a division of my application for patent for cloth measuring and tubing machine Serial No. 457,985, filed September 11, 1942,

The invention relates to machines for winding fabric on successive cores, particularly Vin the state for delivery to the selling trade, for which purpose it is desired that, the lengths of the fabrics in the different wound masses being the same, all the masses shall be wound so as nearly as possible to have the same density.

For this purpose the machine ofthis invention contemplates presence therein, with a rotary drum around which the fabric is to extend and means to hold the fabric in contact with and against slippage relatively to its periphery, and With a rotary core on which to wind the fabric, means by which to drive the core from the drum through slip-friction which is capable of being varied manually by the attendant. Thereby, though as the wound fabric mass being formed on the core tends to rotate at a constantly increasing peripheral speed, with attendant increase in tension on the fabric and increasey in density of the wound mass, the operator may from time to time, by adjustment of the mentioned-slip-friction core-driving means, compensate for such tendency so as to attain tension which during each operation will as nearly as possible approximate constancy and a state of density which in a succession of the wound masses will be substantially uniform. In carrying out my invention I have constructed the machine specifically as follows: The drum has its axis horizontal and the fabric, being delivered from below the drum, extends over the drum and then down under a vfreely rotative roll parallel with the drum (and which affords in part the means to hold the fabric in contact with and against slippage relatively to the drums periphery) and then up to the core, which is also parallel with the drum; the drum, being suitably driven, drives the core through atransmission including a clutch comprising coaxial clutchmembers whose axis is also parallel with the drum and one of which is driven by the drum and the other of which drives the clutch; and

' y the manual adjustment of the clutch is effected by a clamping means including a screw axially related to the two clutch members and having a manually operated nut. Thereby, the nut being ject to friction resistance) during the winding,

should be rchecked instantly when the drum is stopped by stopping the motor, else the fabric would overrun. Hence, my invention further contemplates control means so devised that, When moved in one direction, it will stop the motor and brake said core and, when moved in the opposite direction, it will start the motor and release the core. Y

In the drawings,

Fig. 2 is a side elevation thereof with a part of the near standard broken away;

`Fig. 3 shows the winding means mainly in longitudinal section;

Fig. 4'is a section on line 4-4 of Fig. 3;

Fig. 5 shows the electric circuit; and

Fig. 6 is an enlarged view of parts Which include the clutch-member 4I appearing in Fig. 1 'and viewed the same as in that figure.

The frame includes two standards I connected by bars 2. What Il term a carrier-rack is varranged to slide from one toward the other standard Vand comprises a rail 3 connecting a pair of uprights 4 also connected by a bar 4a, This rail adjustment of the nut may be necessary by his j other hand.

The machine will usually be driven by a motor having means to start and stop the same and the fabric-supply will usually be a mass of the fabric wound on a core or beam. This core, while more or less free to turn (though preferably subhas vrunners 3a which rest on rollers la journaled in the standards, the left-hand one being toothed to form a rack and the corresponding roller existing as a pinion engaged with such rack and having a hand-wheel Ib whereby manually Vto shift the carrier-rackV laterally so that the selvages of the fabric may be lined up by the operator with the ends of the wound mass being formed. So much is the usual construction. The carrier-rack is supported in upright position by having the upper ends' of its uprights engaged with a shaft 2| to be referred to, said uprights having open bearings 5 to receive the shaft 6 of a beam or core 'l on which the supply-mass of fabric a is wound.

In the left-hand standard is journaled the axial portion 8 of a pair of peripherally grooved drums 9 and Il), the rotary element thus formed constituting a support for and having a socket 8a to receive the adjoining squared end of the shaft 6, whereby such support forms a chuckconfined to rotate with the beam 1. Fixed studs Il, one below and the other above said element, project from the frame and to the lower one of these a band or strap I2 is connected, the upper terminal of the band penetrating the other stud and being threaded and having a nut i3 for tightening the band, which, between the studs, bears against the periphery of the drum 9. Thus a brake is formed which, on adjustment of the nut, opposes some constant frictional resistance to rotation of the beam and hence the delivery of the fabric wound thereon, A pair of semicircular brake-shoes i4 pivoted to upper stud Il `member'of the chuck). `plugfmemberfare both ellipticalin cross-section and of such dimensions that each may rotate V55 4| :journaled in the `standard and having a clutch-diski'42 fast thereto. A sprocket-disk 43 is rotative on clutch member 4| and between the disks 42-43 and fast to one of them is a felt I 9 of a solenoid 2|] or equivalent electrically ener- V'510 gized means. In short, there is -a twin-.clutch the drum 9 of which (and hence thebeamf'l'l is subject to constant resistance to rotationfjanli the drum l0 of which is subject to resistance to rotation only on call.

Ata suitable elevationabove and somewhat rearward of the beam 21 there is journa'led'in the 'frame the shaft 2| of a measuring drum -22.

`The fabric is to extend over and well around "this drum, .as back of it and then down --and 120 under an idleroll 23 forward of the drum and journaled vin the frame, then back and forth '.around guide-bars -24l supported in suitable brackets 25 and then to the core b` onto which the fabric is finally wound for'deliverytothej25 customer. In the upper part of the carrier-'rack a pressure roll 22a (Fig. 2) is journaled 'and under the pressure of-springsf22b holds/the fabric pressed againstthe drum.
