This invention relates to sin improvement in reels and is particularly directed to the construction of "the stop motion mechanism whereby the machine is stopped after a predetermined amount of thread has been skeined thereon, means also being provided whereby the machine will stop automatically upon the breaking of thread. V

In the drawings accompany ng thisapplication:

Fig. 1 is a view in front elevationof a machine embodying my invention Fig. 2 is a view on the line 2-2 of F g. 1;

Fig. 3 is a view on the line 33 of Fig. 1;

Fig. 4 shows the position of certain parts of the stop motion mechanism when the desired amount of thread has been skelned; and

Fig. 5 shows the position of certain parts of the mechanism assumed when a thread breaks. r v i I Referring to the drawings 1n detail, 1 desig- I nates the'fly and 2 the fly shaft. The fly shaft 2 extends lengthwise of the machine as will be seen from Fig. 1 and carriesa plurality of spiders, two of these spiders having been shown in the drawings merely by way of illustration. The ends of the shaft are mounted in suitable bearings in the end frames of the machine designated .3 ande.

At the left hand end of the fly shaft 2, as viewed in Fig. 1, is a frictiondisc 5 which 18 driven from a drive disc 6 mounted "below the same. the disc 5 when theinachin'e 1s'1n operation resting on the periphery of the drive disc 6. The drive discis mounted on drive shaft 7 driven from any suitable source of power.

8 designates a brake arm pivoted to the end ,0 of the machine at 9. The free end of the brake arm 8 carries a roller 10 adapted to engage the upper face of a. Weighted control handle 11 pivoted at 12. Theupper end of this control handle 11 is extended to the left, as viewed in Fig. 3, to provide an extension 13 to which is attached a rod- '14,,the lower end of which is attached to a foot pedal 15. Under certain conditions of operation depression of the pedal-15 to raise the rod 14 9 will release the brake Sand swing the control handle 11 into locked positon as "will be explained hereinafter. I

16'designates a rocker shaft whiclr extends longitudinally of the machine, while 16' i V designates a 'stopfmotion shaft which carr'ies 6 at its left hand end,-as'viewed inFig. 1, a latching member 17. This latching'member is provided with a latching notch near its upper end. designated 18 which under certain conditions is adapted to cooperate with a pin 19 carried on the weighted control handle 11. About midway of the latch 17 and on the face thereof which is adjacent the pin'19 is a cam lug 20. l v

Extendinglengthwise of the machine and mounted on suitable brackets'22 on rocker shaft '16 is a bar 21 havinga rocking motion imparted to it by mechanism not shown, inasmuch as this construction is usual in machines ofthis general type. l r I The rocker shaft 16 and stop motion shaft 16 are mounted in brackets B.

The stop motion shaft16"carries a pluthese arms being provided at its outer end with a guide eye 25 through which the thread 26 from spools 27 is led upwardly to the fly 1,

the threadipassingthrough'a guide eye 28 below the eye 25. i j V V i The stop motion shaft 16' is also provided ,Fig. 2. I

Below' the stop motion shaft and extending 'rality of upwardly extending brackets 23 which pivotally mount faller. wires 2 1 each "of transversely of the machine; that is to say,

inwardly beneath the drive shaft 7 is a pull rod 30 provided with an adjustable knock off collar Sladjacent its outer end and at its lnner end with a weight 82 pivotally attached thereto. The weight is mounted-on a fixed pivot 32. '33 designates the reset handle on the outer end of the pull rod 30. The M weight is provided witha nose N' adapted to cooperate with one armofa weighted hell I crank lever Ii. This lever provided with'a pin 34 adapted to be engaged pointer 35 which is adjustably carried on a count gear 1 86 and moves with said gear. This-pointer 35 is made adjustable so as to vary the timeat which the same will strike the pin 34 on the lever L, thereby enabling the amount of thread to the skein which is controlled by the pointer, as will be pointed out, to be varied as desired. The lever L is provided for preventing the operator from stopping the machine before the full yardage for which the machine has beenset has been reeled.

The drive for the count gear 36 is through a worm 37 mounted on'apivoted shaft'38 mounted above the gear and carrying at its other end, that is to say, on the opposite side of the pivot for the shaft from the worm 37 a worm gear 39 meshing with a worm 40 on the fly shaft 2.

The shaft 38 is held in position to maintain the worm 37 in mesh with the teeth of the count gear 36 and the worm gear 39 in mesh with the worm 4O by a latch 41. I

Pivoted to the righthand end frame of the -machine is a bell crank lever 42 pivoted at 43, one arm of this lever having a slot and pin connection44 with the end of a connector 45 the other end of which is pivotally attached to the weight 32. The arm 46 of bell crank lever 42 is adapted to engage thelatching finger 41 as will be presently described and also is provided with a lug 47 which is adaptedto engage alug 48. on the shaft 38 so that when the bell crank is rocked about its pivot 43 to the dotted line position shown in Fig. 2 it will first unlatch or release the finger 41 and thereafter by engagement with the lug 48 raise the left hand end of the shaft 38 to disengage the worm 37 from count gear 36 and worm gear 39 from worm 40.

In normal operation, that is to say, when the stop motion mechanism is to operate merely to stop the machine after a predetermined length of thread has been skeined, the count gear 36 driven from the'fly shaft 2 will move 7 in the direction of the'arrow thereon until the pointer 35 which previously has been set engages the pin 34 on the weighted bell crank lever L. This will cause the lever to be rocked to disengage itsarm from nose N on the weight 32, and the latter thus being unlatched will rock to the right as viewed in Fig. 2 about its pivot 32, dropping to the dotted line position of Fig. 2. In moving to this position the weight 32'will pull the connector 45 downwardly and thereby through the bell crank lever 42 move the worm 37 upwardly out of engagement with the count gear and simultaneously the worm wheel 39 out of engagementwith the worm 40 on fly shaft 2. v r

This same movementof the weight 32 will move the pull rod 30 inwardly of the machine,

dotted line position shown therein and the knock off collar 31 will engage the extension 49 on the weight lever 29, so as to raise the weight. upwardly from the position shown in Fig. 2

- front of the machine.

we1ght'32 to its original position, the nose N and to rock the stop motion shaft 16' clockwise, as viewed in Fig. 2, anti-clockwise as viewed in Fig. 3. This motion of the stop motion shaft 16 will, as will be understood rock the latch 17 to the left from the position shown in Fig. 3, so as to pull the notch 18 therein away from the latching pin19 on the control handle 11 and permit the latter to drop. This condition is illustrated in Fig. 4. The dropping of the control handle 11 will raise the brake arm 8 upwardly to-carry the friction. disc 5 away from the face of the drive disc. 6 and apply the brake. The machine, therefore, is now at rest.

The parts remain in this position until the machine is ready to be set into operation again, whereupon it is necessary first to reset the pull rod 30 which is done by grasping the handle 33. and pullingfthe rod toward the This will restore the slipping past the arm of bell crank L, and restore the shaft 38 toits original driving pos1t1on, that is, with the worm 37 inengagement with the face of the count gear 36 and the worm gear .39 in engagement with the worm40 ontheflyshaft2. a i

Movement or resetting of the rod 30 will also permit the counterweight 29 to drop to its original position, which will rock the stop motion shaft 16 clockwise as viewed in Fig. 4, to impart a corresponding movement to latchingmember 17, to permit the control member 11 again to be raised into the position of Fig. 3, this return movement being prevented until the rod 30 is reset by the lug 20 on the-latching member 17 which as shown in Fig. 4 moves into thepath of the pin 19 on control member 11 when the machine trips.

It-is now merely necessary to depress the foot pedal 15 to raise the control member 11 to latched position, this same operation removing the brake 8 and permitting friction giso 5 to drop upon the periphery of drive isc 6. i

The, description thus far given of the stop motion mechanism is normal. I will now give a description of operation when a thread breaks in the machine, at which time it is desired to stop the machine automatically and as the thread may break at anytime during the operation of the machine it is to be understood of course that the pointer 35 'on the count gear 36 cannot be relied upon for this purpose. As previously described, the threads 26 are threaded through eyes 25 on faller wires 24. These faller wires are somounted in brackets '23 that in the event of a thread breaking the wires will fall to the left, as viewed inFig. 2. that is, to the left as viewed 1n Fig. 2 to the I n this event the bar'21 which it will be remembered is given an oscillatory or rocking movement toward and'away from the front of the machine, engages the lower end of the mount 51 whichcarries the-fal-lerwire correin operation.

sponding to the broken thread. l he effect of this is to again raise the weight 29 as occurred when the count gear 36 functioned to stop the machineand to at the same time rock the stop motion shaft 16' clockwise, as viewed in Fig. :2, and anti-clockwise, as viewed in Fig. 3, with the result that the latch 17 will be moved out of locking position, the controller arm llwill fall, raise the friction pulley 15 from the face of the driving disc 6 and apply the-brake 8 and the machine again will come to rest.

' As soon as the controller arm 11 falls the latch 17 will moveback to its extreme right hand position again, as shown in Fig. 5, under the action of the weight 29 instead of remaining in its outward position as it did when-the count gear operated, the rod 30 having 'remained in set position so that the collar 31 is in inoperative position, and consequently the cam lug 20 will lie out of the path of the pin I'count gear, the combination of "a "pivoted 19 on latching memb er 11. After the broken thread is tied the operator by merely depressing the footpedal can again start the machine It willbe seen from the foregoing, therefore, that I have provided a reeling machine in which the control member 11 is retained in operative positionunless released by the measuring or count wheel 36', and that means are provided for resetting the machine until the.

measuring device is reset.

It will be seen alsothat -I have provided a construction whereby tripping of the machine to stop the same deliberately before the full yardage is reeled is prevented.

It is to be understood that changes may be made in the details of construction above described within the purview of my invention.
