WINDING MACHINE.

Application filed AOctober 1, 1924. Serial No.- 740,979.

To all 107mm it may concern:

Be it known that I, JOHN O. McKnAN, a citizen of the United States, and resident of lestield, in the county of Hamp-y den and State of Massachusetts, have invented a new and useful Improvement in Vinding Machines, of which the following is a specification.

One object of my invention is to provide certain improvements in winding machines whereby floor spaceis saved and the number of angles for the yarn to turn may be materially reduced between the supply spool and the windingA head, thereby lessening the tension on the yarn andy obviating its breakage toA a greater extent than heretofore; such improvements including `a common supply spool arranged vertically at one end of the winding machine as distinguished from supply spools arranged horizontally upon both sides of the machine; means such as spreaders being provided for dividing the yarn strands and leading them to the opposite sides of they machine. y y

A further object is to provide both automatic and manually operated brakes for the supply spool, the automatic brake serving to prevent the spool from running ahead when the machine is in operation and the manually operated brake serving Yto prevent the yarnY strands from sagging as the machine is being stopped.

A further Vobject is to provide a novel bearing support for the supply spool, constructed to permit the ready'placement and removal of the spool, said bearing support also carrying the automatic and manually operated brakes for the spool.

A still further object is to provide novel, manually operated means such as a belt shifting lever for gradually starting the winding, step by step, to insure easy starting and to prevent jerks on the yarn tending to break the same, the stop for the intermediate position of the starting lever being adjustable to obtain the best results.

A still further object is to provide a telltale on the winding shaft for indicating the speed ofthe shaft so that when the shaft reaches a predetermined speed the starting lever may be moved from its intermediate position to its next position to bring the winding mechanism up to its full speed.

. A practical embodiment of my invention 1s represented in the accompanying draw ings, in which n Fig. l represents in side elevation so much ofa winding machine as will give a clear understanding of my improvements applied thereto. i

The winding machine frame isdenoted by l and the `winding heads on opposite sides of the machine by EZ. f The'drive for the winding machine includes the drive shaft 3, provided with the fast and loose pulleys 4 and 5. vThe driving belvti leads from any suitable source of power, not 'shown herein. The drive shaft 3 is connected to the winding shaft v"i of the y through the usual intermediate belt and The winding shaft 7- the machine for visually indicating to the operator the rotative speed of the winding shaft.

The means which I have shown for supplying yarn to the winding machine comprises a vertically arranged supply spool 9 Whiclris removably positioned upon the base 10 of a suitable bearing support, located at one end o1 the machine. This bearing support is provided with a base bearing 11 for the lower end of the supply spool shaft 12, the said shaft being provided with a spool core block 13 and bearing block 14. rlhe base 10 of the bearing support is provided with an upright comprising a lower member 15 and an upper member 16. A swinging to-p bearing mechanism for the supply spool comprises a fixed collar 17, adjustably secured alongl the member 16 by the set screw 18, and a vertically movable laterallj7 swinging arm 19 which is provided with a top bearing 20. The upper end of the supply spool shaft 12 is provided with the core block 21 and bearing block 22, the bearing block servving to receive the top bearing 2O of the swinging arm 19. The collar 17'is provided with a recess 23 for receiving the arm 19 and holding it in its operative position.

rThe automatic brake mechanism for preventing the supply spool from running ahead when the machine is in operation is constructed, arranged and operated as follows A collar 24 is adjustably positioned by the set screw 25 on the upper member 16 of the upright, from which collar projects an arm 26 carrying a pulley 27. The brake lever comprises a collar 28 rotatablymounted on the Lipper member 16, from which collar projects in one direction an arm 2 9 carrying a brake shoe 30 and in another direction anarm 31, from which leads a flexible cony nection 32 over the pulley 27, which flexible connection is provided with a weight 33, tending tohold the brake shoe 30 against the side of the supply spool with the rcquired amount of friction.

The manually operated brake Vmanipulated to prevent the yarn strands from sagging between the supply spool and the winding heads when the machineris stopping, is constructed, arranged and operated as follows:

A collar 34 is adjustably secured by a set screw 35 to the upper member 16 of the upright, whichcollar forms a support for a collar 36, from which projects a laterally swinging resilient arm 37, carrying a brake shoe 38V and a handle 39. This brake shoe 38 is normally held lby the arm 37 a short distance above the upper end' of the supply spool but when the machine is'being stopped', the operator can grasp the handle 39 and depress the arm 37 to bring the brake shoe 38 into frictional contact with the upper end of the said spool, to keep the proper tension thereon.

To remove the supply spool, the flexible connection 32 of the automatic brake mechanism may be unshipped from the pulley 27 and the lever swung around in position out of the way of! the spool. rlhe manually operated'brake arm 37 may also be swung laterally out of the way of the spool. rllhe top bearing arm 19 may then be raised and swung laterally out of the way, thus giving ample room for the removal of the supply spool, the parts remaining in this position until the placing of another supply spool when the parts may be returned to their operative positions.

The means which I have shown for dividing the yarn strands and leading them to the opposite sides of the machine is herein shown as comprising spreaders 40, projecting latm erally from one end of the machine frame, which spreaders are provided with eyes 41 which not only serve to separate the yarn strands into groups as they lead off from the supply spool but also serving to separate the individual strands and lead them to their respective winding heads 2. lt will be seen that because of the vertical arrangement of the supply spool these spreaders serve to lead the yarn strands to the winding heads with aiminimum number' of turns, thereby materially reducing the tension on the yarn strands and obviating to a very great extent the liability of the strands to break.

A manually operated means is provided for starting the Winding gradually and thus preventing the jerks on the yarn, which means is constructed, arranged and'operated as follows:

A loop 42 of a beltshifter embraces` the driving belt 6, from which loop leads a belt shifter-rod 43 lengthwise of the machine to the end adjacent the yarn supply spool. The lever for operating the belt shifter is denoted at 44, which lever is pivoted on a bracket 45 projecting from the end of the winding machine frame, the short arm 46 of which lever is connected to the belt shifter rod 43 and the long arm 47 of which lever extends to a position in proximity to the yarn supply spool so that a single operator may control the starting and stopping of the machine as well as apply the manually operated brake for thesupply spool.A i Adjustablemeans are provided for causing` the belt shifting or Astarting lever to be moved in successive steps so that the winding operation will be started gradually and thereby eliminate unduestrain on the yarn, which means is constructed as follows:

An arm 48 projects laterally from the bracket 4'5, which arm is Lprovided with an intermediate stop block 49, adjustable toward and away from the bracket 45 by an adjusting screw 50, bolts 51 passing through Ell ' y starting lever.

Watch the tell-tale 8 and When the Winding operationhas gradually come up to the predetermined speed, the Varm 47 of theV starting lever maybe slightly raised and its movement completed along the top of the block 49 to its full running position. The arm i8 is provided With uprising abu'tments 53, 54, for limiting the movement of the From the above v that I have provided certain improvements in Winding machines whereby the Winding of the yarn is materially facilitated and the control thereof is better regulated, and

at the same time a material amount of ioory space is saved.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts Without departing invention; hence, I
