'2 Claims. (Cl. 74-37) 'Ifhis invention relates to winding machines these machines W are typical of the kind with variously employed for example in the textile winding units in multiple serially arranged in industry to wind yarns into conical or cylindric straight rows along their opposite sides, the packages (ordinarilyreferred to as cones or bobbin B of each such winding unit serving cheeses) of a convenient size suitable for yarn to a reciprocating guide G incident to 60 use in knitting machines and the like, to wind formation of a yarn package or cone C in a yarns on spools, etc.; and has more particular manner well understood in this art. reference to that type of winding machines To transport the operatives back and forth with winding units in multiple arranged serially within the aisles A past the winding units along l0 in straight rows along opposite sides. When contiguous sides of adjacent winding machines 65 used in numbers, such machines are generally W, I provide in each instance a conveyance havgrouped in gangs with aisles between them for ing the form of a carriage with wheels l1 to operatives to pass back and forth in attendrun on track rails 12 that extend centrally ing therspinning units at contiguous sides of through the aisle A. The means for progressing neighboring machines.` Accordingly, the task the carriage 10 along the track rails 12 includes 70; of the operatives is extremely arduous and tira continuously driven endless propelling cable ing in view of the extensive length of the maor chain 13 which is trained for movement in a chines and the distance which must therefore vertical plane over positionally fixed guide wheels be traversed repeatedly toreplace empty bob- 14, 15 with journal support medially of the ends bins, connect broken yarn ends, etc. of the track 11 in bearings 16, 1'7. By reference 7,5,A

In the main, my invention is directed toward to Figs. II-IV it will be observed that the caralleviating the unsatisfactory condition to which riage 10 is equipped with a clutch means 20 attention has been directed, that is to say, I comprising a pair of grip members 21, 22 that aim` to minimize fatigue incident to running are independently fulcrumed to a fixed drop 25 spinning machines of the kind referred to. This bracket 23 on the carriage 10 and have their 80` end I attain, as hereinafter fully disclosed, outer ends connected by a coupling link 24. The through provision of automatically reversing grip members 21, 22 may be formed with teeth conveyances whereby the operatives are carried as shown to engage interstices of the propelling back and forth in the aisles between the machain 13. Still referring to Figs. II-IV, it will be chines. noted that the link 24 is pivotally connected 85 Further objects of my invention are to proto the end of an arm 25 on a shaft 26, said shaft vide, in connection with conveyances suitable to being rockable in the depending portion 2'7 of a the described purpose, for stoppage under manframe 28 capable of rocking movement on an ual control at any point along the line of travel; axis 29 at one end of the carriage 10. With and also to provide for automatic disposal of this arrangement it will be apparent that the 90 empty spindles, etc. collected during eaclr travtoothed clutch members 21, 22 are concurrently erse of the conveyances. operable so that the upper one 21 is engaged Still other objects and attendant advantages with the top run of the propelling chain 13 will appear in the course of the detailed desimultaneously with disengagement of the lower '40. scription following in connection with the atone 22 from the oppositely moving bottom run 95 tached drawings, whereof Fig. I is a plan view of said chain, and vice versa.

For 190 viewed as from below Fig. I. the purpose of controlling the clutch means to Figs. III and IV are fragmentary illustraautomatically bring about reversals in the travel tions, on a larger scale, showing different posiof the carriage 10, I secure on the rock shaft tions of a novel clutch means embodied in my 26 a finger 31 adapted to be tripped by fixed 50. invention. stops 32, 33 near the opposite ends of the track 105 With more detailed reference to these illus- 12. With the clutch means in the position of trations, I have depicted in Fig. I a group of Figs. II and III, the carriage 10 will obviously winding machines W arranged side by side, afbe moved to the left as indicated by the arrow, ter common practice in gang grouping, with shown on the first mentioned figure, until the traversing aisles A between them. As shown, trip finger 31 encounters the stop 32 which oc- I 'ljo curs at just about the time when said carriage nears the limit of its movement in the indicated direction. As a consequence of the encounter of the trip ringer 3l with the stop 32, the clutch 20 is actuated and the upper toothed member 2l withdrawn from the top chain run, while the lower toothed member 22 is engaged with the bottom chain run, the new position of the parts being maintained through swinging of the counterweighted lever 30 to the opposite side of the vertical dead center in an obvious manner. The carriage 10 is thereupon propelled in the reverse direction until the trip nger 31 encounters the stop 33, with consequent restoration o the clutch 20 to the illustrated position at the end of 'the travel to the right, in preparation for the succeeding return movement.. The carriage` 10 is thus moved continuously and automatically back and forth in the aisle A.

To enable stoppage at any point along the lin of travel I form the frame 28 with a foot treadle 34 which is conveniently accessible to the operative when seated on a swivel stool 35 centrally of the carriage 10. Depression of the treadle 34 obviously causes the frame 2S to be swung on its axis 29, thereby to bring the clutch members 2l, 22 to a neutral position so that neither of them engages the propelling sprocket chain 13, as shown in Fig. IV, with consequent cessation in the travel of the carriage 10.

At each side, the carriage 10 is equipped with a magazine or holder 36 for lled or loaded bobbins B which are withdrawable successively through an outlet at 37; as well as with a receiver 38 for the empty bobbins, said receiver' having an inclined bottom, as shown in Fig. III, for capacity to discharge endwise through a door 39. This door 39 is pivoted to the receiver 38 so as to swing upward, and has an actuating arm 40 adapted to be engaged by a stop 41 at the end of the carriage travel with resultant swinging of said door to open position and discharge of the collected empty bobbins B into a waiting receptacle 42 adjacent the stop 41. The described construction and operation of course holds for the conveying equipment for an operative in each of the aisles A.

rIhe several propelling chains 13 may be driven from a common source of power, and to this end, the guide wheels 15 are shown as mounted on a line shaft 45 which is coordinated, by a belt or chain 46, with a countershaft 47 arranged to be driven in turn, through speed reduction gearing 48, by an electric motor 49. In practice. the speed predetermined for the propelling chains 13 is such that the operatives are afforded ample time to replace empty bobbins B and give whatever other attention may be required at each of the winding units incident to passage of the carriage 10 back and forth between neighboring machines W, the new bobbins B being within easy reach by virtue of support of the holders or magazines 36 at arm level, while the replaced empty bobbins B may be readily dropped into the receivers 38 for automatic discharge later under gravity influence into the collecting boxes 42 at the ends of the machines W in the manner previously explained.

While I have herein shown and described my invention in connection with yarn winding machines W, I do not wish to be limited to this particular field alone since it may obviously be used with attainment of corresponding advantage in connection with other machines for winding or spooling materials in strand form even including Wire.

Having thus described my invention, I claim:

1. In winding machines with longitudinally arranged series of winding units, including a wheeled carriage to support an operative, and a rail track for the carriage extending alongside the winding machine, a constantly-moving endless chain lengthwise intermediate the track rails, and means comprising opposingly-active independently-fulcrumed grip members, subject to counterbalancing-influence, supported by the carriage for alternate coupling engagement with the respective flights of the endless chain to automatically propel said carriage along the track and convey the operative back and forth past the winding units.

2. In winding machines With longitudinally arranged series of winding units, including a wheeled carriage to support an operative, and a rail track for the carriage extending alongside the winding machine, a constantly-moving endless chain progressing in a vertical plane lengthwise medially intermediate the track rails, means comprising opposingly-toothed independently-fulcrumed members, subject to counterbalancing-innuence, supported by a drop-bracket from the carriage for alternate coupling engagement with the upper and lower flights of the endless chain to automatically propel said carriage along the track and convey the operative back and forth past the winding units, and manually-operable means whereby the carriage may be stopped at any point along its path of travel.
