STRAND REELING 4MACHINE t# ATTORNEY Patented Jan. 22, 1935 f UNITED STATES STRAND BEELING MACHINE Samuel E. Brillhart and Austin Le Boutilller. Baltimore, Md., assignors to Western Electric Oompany, Incorporated, New York, N.-Y., a corporation of New York Application November z, 19:2, seria No. maar 12 claims. (c1. :4e-z5 This invention relates to strand reeling machines. and more particularly to such machines where it is desirable that the flow of the strand to be reeled to theireels of the reeling machine shall be uninterrupted and of substantially unvarying velocity.'

The primary object of the invention is to permit continuous reeling of a strand at substantialf ly unvarying speed and without imposing injurious stresses or changes of stress upon the strand. One embodiment of the invention presents a reeling machine having a rotatable reel holding frame with a plurality of reels mounted therein 1 and means to drive the reels independently of l5 each other at'relatively equal and substantially uniform speed and with adjustably predeterminable maximum driving power delivered thereby to the reels. The parts are soarranged and related that when a reel is nearly filled, a partial v rotation of the frame will bring an empty. reel,

already rotating at strand winding speed, into winding position and means are provided to catch and cut the strand and attach it to the empty reel without interrupting or slackening the ow ofthe strand. l

v Other objects and advantages of the invention will appear more fully from the following detailed description, taken in connection with the accompanying drawings, wherein Fig. 1 is a broken view lin front elevation and partly in vertical section of a strand reeling machine embodying the invention;

Fig. 2 is a detached perspective view of a reel drive arm showing theV strand -catching head 35 thereof;

Fig 3 is a broken plan view partly in horizontal section on the line 3--3 of Fig. l;

4 is an enlarged fragmentary view in front` elevation showing the strand catching, severing .40 and clamping means. and

Fig. 5 is a similar view in reverse plan on the line 5-5-of Fig. 4.

In carrying out the invention as herein disclosed there is employed a strand reeling machine hav- 45 inga mounting base 10 securely mounted on a floor or other foundation. 'Ihe base 10 carries an upstanding pivot pillar 11 on which ismounted with freedom to rotate thereon a bilaterally symmetrical reel carrying frame generally indicated 50 by the numeral 12 comprising a base portion 13, a top casing 14, and an intermediate central pillar 15, by which latter the frame base 13 andv the top casing 14 are spaced apart and held together. 5 5 Beside the general structure thus far described there is provided a separate distributor casing 1c containing mechanism for distributing the coils of a strand being wound on a reel in regular order.v

The nature and details of this mechanism are irrelevant to the present invention and so are not disclosed here. being well known in winding and reeling machines generally.. It sunlces to note that the distributor is driven by an angular faced metal sheave 17 deriving power from the reeling mechanism as will be described hereinafter. A

strand being reeled is guided by horizontal and vertical guide rolls 18-18, between which the strand 20 passes and which are carried up and down by the `distributor mechanism (not shown) A vertical guide roll V19 is used to suppressl excessive lateral displacement of the ystrand when it is manipulated as hereinafter described.

The entire frame 12 is rotatable on the pillar 11, and is provided on the upper face of the top 14 with two identical latches 21---21` which cooperate with a complementary notched locking member 22 formed on the casing 16. The latches 21 are. spring pressed vin any approved manner (not shown) to releasably engage the member 22 for holding the reel frame 12 in either 'of two positons 180 apart.

The frame 12 and its associated parts are adapted and arranged to hold and drive a pair of strand winding or take-

up reels

23 and 24. In the frame base 13 is mounted a pair of cone-topped, freely rotatable pivots 25-25 to engage in central axial vsockets in the lower heads 28-28 of the

reels

23 and 24 to support the reels. The pivots 25 25 are retractible downwardly by any convenient mechanism (not shown) actuated by the levers or pedals 26-28 to be disengaged individually from the reels.

The base 13 is further provided'with fixed circular bottom reel guards 27-27 coaxial with and a little larger in diameter than the neighboring, lower reel heads 23-28.

At its Iupper end each reel 23 o`r 24 is centrally engaged by a spring. pressed plug 29, as shown in the right hand side of Fig. l; which enters a central axial socket in the upper reel head 30. The plug '29 has formed thereon an axial longitudinally bored stem seatedin a corresponding axial bore in the lower end of a reel drive shaft 31 journalled in antifriction bearings mounted in the'top casing 14. I'he plug 29 has a limited freedom of longitudinal motion relative to the shaft 31, being held in placev by a set screw 82 lpassing through the wall of the bore in the lower Each arm 34 is formed at its outward extremitywith a head 35, ilattened horizontally and formed with a wedge shaped notch 36 whose function will appear hereinafter.

Just above its lower bearingthe shaft 31 has keyed thereto a gear 37, which through -interlmediate gears 38 metal sheave 40 corresponding and juxtaposed to the similar drive 4 sheave 17 of the distributor. A rubber faced grooved sheave 41 (Fig. 3) is rotatably mounted on an arm 42 pivoted in a lug 43 formed on the casing 16. For simplicity this sheave 41 and the arm 42 and lug 43 are omitted from Fig. 1. The arm 42 is spring pressed by any approved means (not shown) to keep the rubber faced sheave 41 normally in contact with the sheaves 40 and 17 whereby the sheave 17 and therewith the distributor mechanism are driven from the shaft 31. When the frame 12 is rotated on thepillar 11, as hereinafter described, the arm 42 yields to permit the sheave 40 to pass the sheave 41.

Near its upper end, the shaft 31 has keyed thereto a belt pulley 44 which is driven by a corresponding belt 45 from a double grooved belt pulley 46 keyed to a vertical central drive shaft 47 suitably journaled in antlfriction bearings carried by the casing .14.' The pulley 46 also drives a second belt 145 extending to the left in Fig. 1 and in turn driving a twin set of mechanism on the left of the shaft 47, corresponding to that on the right. A bevel gear 48 keyed to the upper part of the shaft 47 is driven by a coactingbevel gear keyed to a main power shaft 49 driven by any approved power source (not shown).

A bell crank having three arms 50, 51 and 52 I is pivoted on a pin 53 mounted in the casing 14.

To the outer end of the arm 52 is attached one end of a tension spring 54 whose othervend is anchored to the casing 14 by any approved tension adjusting means such as the turnscrew dehandle 59 against vice generally indicated at 55. The outer end of the bell crank arm 51 carries a belt tightener pulley 56 mounted to rotate thereon on antifriction bearings and shown in Fig. 3 as pressing against the belt 45 under the tension of the spring 54. The third arm 50 of the bell crank is provided with a pin 57 extending up through the top of the casing 14 through an arcuate slot 58 therein. A handle 59 is mounted on the pin 57 and can be longitudinally slid thereon against the spring tension of a spring 60 interposed between the handle and the pin. At the end of the slot 56 away from the spring 54 is located a recess 61 adapted to receive the lower end of the handle 59 and thereby to lock the bell crank when rotated against'the pull of the spring 54. By lifting the the urge of the spring 60 the crank is released to move under the pull of the spring 54 and` press the tightener pulley 56 against the belt 45.

Near its inner or pivotal end, the arm 51 is attached to a link 62 by means of a pin 63 rigidly mounted in the arm and passing through a slot and 39 drives an angular facedl longitudinally located in one end of the link. The other end of the link is pivoted to the outer end of the arm 64 of'a bell crank mounted lon a pivot p'in 65 carried bythe casing 14. The other arm 66 of this bell crank carries a brake shoe 67 for coaction with the face of the pulley 44. A compression spring 67 abuts at one end against the pin 63 and at the other end against the pivot whereby the link 62 is attached to the arm 64.

At each end of the casing 14 one of a pair of top reel guards 68-68 is rigidly attached to the under surface of the casing. These reel guards are rigid, slightly conical discs, positioned over the reels 23 and l24 coaxially therewith, and are slightly larger than the reels in diameter. Each reel guard 68 is formed with a slot 69 extending inwardly from the periphery of the guard at an acute angle to the radial direction of the guard at the mouth of the slot. The side walls of the slot are parallel to each other and slope from left up to right down (Fig. 4). A pair of strand guide pins .70 and 71 is mounted rigidly on the top of the guard, one on each side of the slot 69.

To describe the operation of the machine, let it be assumed that the machine is running and is reeling or taking-up the strand 20, coming from some undisclosed source, upon a reel on the right hand side in the position of the reel 24 as shown in Fig. l. Let it be assumed that this reel is full and lit is desired to change the reeling of the strand tov an empty reel. Let it be further assumed that there is no reel in the left side of the machine in the position of reel 23 as shown in Fig. 1 and that the left hand handle 59 is in the corresponding socket 61. In this position of the handle 59 the left hand mechanism is stationary as the corresponding tightener pulley 56 is drawn back leaving the belt 145 slack and the `corre sponding brake shoe 67 is pressed against the corresponding pulley 44 holding the same motionless.

By actuating the left hand lever 26 the corresponding pivot is drawn down into the base. An empty take-up reel is now placed in position and the lever 26 returned. The pivot 25 rises into the central socket of thev reel head 28 and lifts the reel. The plug 29 enters the central socket of the reel head and the spring arms 34 have their heads engaged frictionally with the top surface of the upper reel head 30.

The handle 59 at the left is lifted out of the recess 61 and allowed to swing under the pull of the tension spring 54. The bell crank 50, 5l, 52 rotates into a position corresponding to that shown in the right hand side of Fig. 3, thus retracting the brake shoe 67 from the pulley 44 and pressing the tightener pulley 56 against the belt 'bringing the pulley 44 up to speed and with it the shaft 3l, its collar 33 and the reel driving arms 34, which by virtue of their frictional engagement withthe reel head 30 drive the reel. Now the right hand latch 21 is disengaged from the member 22 and the entire frame 12 is rotated 180 clockwise (Fig. 3) until the other latch 21 engages the member 22, bringing the whole into the position shown in Figs. 1 and 3. In the embodiment herein disclosed they frame 12 is turned by hand, although power means may be provided if desired. l

The strand 20 is then lifted, manually or by any suitable device and without interrupting or appreciably affecting its motion, from the path shown in full lines in Fig. 1 and in dotted linesl in Fig. 3 to the path shown in full lines in Figs.

3, 4 and 5, passingthrough the slot 69 'and between the guide pins 'I0 and 71.

Thenext driving arm head 35 which sweeps past the slot 69, catches the strand in its notch 5 36, severs the same at once against the sharp lower edge of the trailing side of the slot 69 and jams the new front end ofzthe strand simultaneously between 'Y the under face of the driving arm headand the upper face of the top reel head 30. Thus the stra'nd is practically instantaneously caught, cut and attached to the new reel to be wound thereby without interrupting'or appreciably affecting its motion.

-The empty reel just before the above takes place is rotating a triiile faster than the full'reel as it is not subject to the drag-of the strand. Hence it picks up the winding pull on the strand immediately and no slack is formed in the strand.

'I'he handle 59 now at the left is pushed over and engaged in the corresponding recess 61 thusl discontinuingy the power and applying the brake to the drive of the full left hand reel 23. When the reel stops, the lever 26 is actuated and the reel removed, thus bringing back the state of affairs presented at the beginning of this consideration of the operation of the machine.

The effectiveness of the drive of the pulley 44 by the'pulley 46 depends upon the pressure of the tightener pulley 56 against the belt 45. The tension ofthe spring 54 is adjusted so that the belt 45 is just about to slip or does slip a trile on the pulley 44 at the desired winding speed' of the strand 20. Then if any extra stress is imposed during the change-over from reel to reel or from any other cause, the reel is able Ato yield momentarily by the slipping ofthe belt 45 on the pulley 44 and pick up again the moment the disturbance has passed. Thus vthe strand is protected against shocks and sudden stresses or V changes of stress while at the same time the reeling of the strand is done continuously.

It will be obvious that the embodiment herein disclosed is only illustrative and not exhaustive of the invention and maybe varied in many ways without departing from the spirit and scope of the linvention as principally characterized by a reeling machine having means to transfer a moving strand from one reel to another without affecting the progress of the strand in combination with means to protect the moving strand at all times from sudden stresses or changes of stress and.v
