DOUBLING AND WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 422,667, dated March 4, 1890.

Application filed February 20, 1889. Serial No. 300,564 (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH E. TYNAN, of Paterson, in the county of Passaic and State of New Jersey, have invented an Improvement in Doubling and Winding Machines, of which the following is a specification.

My invention relates to doubling, twisting,

and analogous machines in which a number of single threads are drawn from bobbins and doubled together and placed upon a single bobbin; and it consists, first, in mechanism for gripping the winding-spindle pulley and stopping it when a thread breaks; secondly, in means for giving tensionto the single threads as they are drawn off from stationary bobbins; thirdly, in a pair of rollers.

roller, then around the feed-roller, and from there downwardly through a guide-eye to the receivingbobbin on the spindle.

In the drawings, Figure l is an elevation of the doubling and winding mechanism, the rails being in section. Fig. 2 is a plan View,

in larger size, of one group of bobbins and the driving mechanism, the winding-spindle being in section. Fig. 3 is an elevation of the same; and Fig. 4 is a plan View below the line as 00, Fig. 5. Fig. 5 is an elevation illustrating the positions of the feed and driving rollers and fallers. Fig. 6 is an elevation, in larger size, of the guide and presser rolls, the bearings being in section. Fig. 7 is an elevation illustrating the direction in which the threads pass, and Fig. 8 is a detached view of the creel-bracket. 7

Reference is hereby made to my application, Serial No. 256,728, filed December 2, 1887, and patented February 19, 1889, for a description of the stop-motion that is applicable to my present invention, and which corresponds, except in the particulars hereinafter named, to the device therein shown for stopping the rotation of the spindle and of the winding and feeding mechanism when one of the threads breaks, and in my present application the same figures are made use of in referring to the parts that correspond to those in my said patent.

The threads to be doubled and wound are supplied from bobbins a a. I have shown three of such bobbins as resting upon abracket or creel b, that projects from the spindle-rail B, and above the bobbins a is a stationary bracket or arm 0, upon whichthe tension-fingers c are supported. These tension-fingers are preferably made of L-shaped wires, the finger portions projecting downwardly and there being eyes at the opposite ends of the wires for the screws 0?, by which the fingers are attached to the bracket 0, and there are stops 0 upon the brackets for holding the fingers in their proper position centrally over the stationary bobbins a. I have provided for allowing such fingers to be turned or moved aside into the posit-ion represented by dotted lines in Fig. 2, fora purpose hereinafter named. The wire composing each finger is sufficiently elastic to allow it to be sprung out of the latch portion of the stop and then swung aside upon its screw 0 into the position indicated by dotted lines, Fig. 2, the important feature in this connection being that the hinged finger can be turned out of the way in removing the bobbin, and when swung back to position it is centrally over the bobbin.

The bobbins a rest upon the creel b, and there are upwardly-projecting pins for holding the bobbins in their positions; but these pins are comparatively short, so that there is room above the bobbins for lifting them oif the pins when any one bobbin is exhausted and for placing in position another bobbin; but to facilitate this operation, as the ranges tom of the spindle-socket b to pass through, and the nut b, that holds the spindle-socket, also holds the bracket or creel. This facilitates the construction and the placing together of the parts, and the arm 0 extends upwardly from the foot of the creel.

In my said patent I have represented fingers around which the thread is twisted as it is drawn off, the twisting being effected by the rotation of the supply-bobbins. present invention the supply-bobbins remain stationary; but in consequence of the fingers 0' being comparatively close to the upper ends of such bobbins each thread is twisted around its finger in consequence of such thread describing a circular path around the head of the bobbin as such thread is pulled rapidly over the bobbins by the winding apparatus, hereinafter described; hence the fingers c act as tension devices, and at the same time form guides to maintain the threads in the proper positions. The threads pass upwardly and in front of thread-guides 35, and between such thread-guides are the hooks of the faller-wires 37, each thread passing through its appropriate hook, and the fallerwire, when a thread breaks, falls backwardly instead of forwardly, as in my said patent.

I provide three faller-wires where there are three bobbins a, and the number is to be increased to correspond to the number of bobbins. Each faller-wire 37 has a finger 62, coming into contact with the rocking lever (35 to lift the same and bring the claw 69 into one of the recesses 7 4: of the driving-roller 13 upon the shaft let, so that said roller 13, act

in g upon the claw ($9, swings the rocking lever 65, and the end thereof pushes -the latch 40 off the back edge of the faller-stand, so that the link 50 allows the belt-lever 33 to descend and slacken the belt 30, and after the thread has been pieced or mended the parts are restored to their normal position, as described in my aforesaid patent. I I

The belt 30 in my present invention is only employed to drive the winding-spindle and pulley 93 and the receiving-bobbin 8, and I make use of a toe 2' upon the lever 33 to act below the pulley 93 to apply friction directly to the same to stop the revolution thereof when either faller-wire 37 acts to allow the lever 33 to descend, as before described, and in order to clamp this pulley 93 firmly I provide a stationary finger 2' that extends up above the pulley, so as not to be in contact therewith except when the lever 33 descends and the toe i slightly raises the pulley 93. In this manner the winding operation is arrested instantly,which is of great importance, because the winding operation in my improvement is so rapid that when the receiving-bobbin is allowed to revolve after either faller-wire comes into action the end of the broken thread might be in a position not easy of access.

In my cessible to the attendant,I carry such threads up above the thread-guides 35 to the guideroller (Z, which is upon a standard d and not too high to be easily reached by the attendant. This guide-roller cl is in a bearing d that is below the roller, so that there is nothing to interfere with the attendant passing the threads over such guide-roller d, and above the guide-roller is a presser-roller e, that is shorter than and rests upon such guide-roller d, and is held in a bearing that passes above it, as shown in Fig. 6, so that the threads upon the roller d draw in automatically below the roller 6 by the tension on the threads, and there is a guide pin or eye 6 upon the bearing 61 against which the threads draw as they pass up to and over the guide-roller d, and from the guide-roller d the three or more threads pass down together through the guide or eye a, and from there they pass around the feedroller 11 and through the detector 64 and the stationary guide-hook 82 down to the receiving-bobbin 8, as in my said patent. It will now be apparent that the hooks upon the three fallerwires 37 guide the threads as'they pass upwardly from the stationary bobbins a and fingers c, and that after passing through such faller-hooks 37 the threads'converge to the guide -pin.e', and should one ofthe threads break the faller-wire and stop-motion will arrestthe winding mechanism in most instances before the broken end reaches the presser-roller 6; hence such end is held by the presser-roller e and is not liable to become entangled with any of the adjacent threads, and can easily be pieced to the end of the thread from another bobbin or the ends of the broken thread joined together, and this presser-roller e maintains a slight tension upon the threads as the"' s down to the guide a", even when all ol supplying-threads may become more or .ss loosened in piecing or mending any of the threads passing from the supply-bobbin, and should either of the said threads be-unusually large at any place the weight of the presser-roller ewill rest principally upon such large thread, and the'tens ion in turning the guide-roller and presser-roller will be principally upon such large thread. There will be a unifying or equalizing action that tends to compensate a difficulty heretofore experienced in doubling-machinesnamely, that the smaller thread is liable to be stretched in drawing it through the various guides, and it will contract and render the larger thread loose when the threads are unwound from the lay-up bobbin. The guide a is preferably upon a traverse-bar 24, as in my said patent, for.

varying the position or lead of the threads as they pass around the feedroller 11.

I have shown in Fi 1 a convenient means for driving the shafts 14: and for varying the speed of such shafts in relation to the main shaft 1 and the receiving-bobbins 8. In this mode of driving the belt is passes from a pul other shaft 1st, in order that such second shaft 14 may be driven in the proper direc tion for the sets of bobbins and-the drivingrolls upon the other side of the machine, and the tightener-pulley m is upon a gudgeon that is adjustable in a slot in the frame A of the machine, and this not only allows for tightening the belt, but it also allows for a difierent-sized pulley 7a to be placed upon the shaft 1 for varying the speed of the belt and of the driving-rolls that receive motion from this belt, whereby the twist given to the threads as they are led upon the receivingbobbins S can be varied.

I claim as my invention-- 1. The combination, with the creel or support upon which two or more stationary bobbins are to be placed,'of a downwardly-projecting tension-finger centrally above each bobbin, the feed-roller for drawing off the threads, a spindle for the bobbins upon which the doubled threads are to be wound, and a stop mechanism for arresting the feed-roller and the winding-spindle in case of the thread breaking, substantially as set forth.

2.
