My invention relates to a thread spooling machine in which the spool holders are arranged in pairs, the spool holders or each pair rotating in opposite directions.

ln machines or this character as now consti-noted, only one spool of a pair can be wound at one time while the other spool remains stationary, the winding of the second spool necessarily being deferred until completion of the 1o jwinding of the first spool.

The principal object of my invention is to enable both spools of each or any pair to be wound simultaneously, and to accomplish this object I allocate a spinning nozzle to each spool 1 5 holder and arranged in cooperative relation with at least each pair of spool holders a shaft or roll extending transversely to and driven independently of the spool holders, the `function of the roll being to receive the thread being goproduced while the spools are being changed. l

It will be apparent from what is said above that the purpose of the invention is to better utilize the capabilities of machines of this type, and this factor is of especial significance `in view of the demand for yarns'of increasingly iiner titre, as a consequence of whichthe output of the machine reckoned in kilograms constantly decreases. This is counteracted by the present invention in acordarme with which the several spools are simultaneously wound. The loss resulting from the change of spools is negligible compared with the gainY resulting from the simultaneous winding of the several spools, more particularly as the time requiredV for changing spools is but very short as compared with the usual present day spinning periods.

The time for changing spools may be further curtailed if the shaft or roll, which is preferably common to all the spool holders and extends transversely thereto, is mounted so as to 'A be capable of being swung into a position over the spools, and if each thread guide is so constructed that the distance between the two threads passing through each thread guide is 5 greatest and the threads are maintained at the extremities of the guide loops at the time that the roll is in its lowermost position to thereby receive the thread during the doiiing period and very shortly after the roll is started to be moved to its top position. In this manner the reception of the thread by the spool to be freshly wound is automatically effected, thus greatly simplifying the procedure.

A further reduction of time in changing spools may be brought about by making the spool holder driving shaft in sections and actuating each section independently. If a long,` continuous roll or shafty be used for taking up the thread produced while the spools are beingA changed, this roll must be made in sections corresponding to the sections of the driving shaft for the spool holders, and in consequence of the sectional construction of the driving shaft4 the stoppage of the spools may be effected inter.-

- mittently and, in case the shaft consists of two v sections for example, the waste may be reduced by approximately one half.

Existing machines may readily be reconstructed toembody the present invention.

An illustrative embodiment of the invention is shown in the accompanying drawings in which Fig. 1 shows a cross sectionof one side of the machine which is two-sided as a rule.

3, as seen Gli? The bobbin-carriers l with their bobbinsZ are arranged in pairs, the left-hand bobbin-carrier rotating counter-clockwise and the right-hand bobbin-carrier rotating clockwise. The bobbincarriers are driven by a driving shaft 7 through the intermediary of toothed wheels. To each bobbin-carrier 1 appertains a spinning nozzle 3.

Between each pair of bobbins and common thereto is arranged a threadeguide 4 comprising the shank 4d and the two guiding eyes 4b at an angle to the shank, the eyes 4b preferably being bent do-wnwardlly out of the plane of the shank 4a. The thread-guide is constructed so that the two threads guided thereby do not touch each other but remain spaced as far apart as possible. To this end, the thread guide construction is such that the two threads are moved outwardly by the resultant of the thread tensions.

The shape of the thread-guide must be such that, while the roller 5 is being swung out, the distance between the two threads carried by it is greater than the clearance of the bobbins to which the said thread-guide appertains.

Extending transversely to the bobbin holder is mounted the long shaft-like roller 5 which each other and prevented by a set. collar.l15.from. displacement in an axial direction. Wheel 10 isz an ordinary spur gear whileA wheel' 11, is` a With gear 10, meshes ,theI- gear, 14 fastened to the shaft 12'wlereas the sprocket sprocket wheel.

Wheel 11 is connected by auchain 16 to the sprocket wheel 13 fastened to the roller 5.,

In turn, shaft l2 is driven by an auxiliary motor 23 through the intermediary of gear train.

20, 2l, 22. Accordingly, the drive of shaft 12 is independent ofl the drive of the bobbin-carrer, viz. of shaft 7.

When the arms 6 arebeing swungout, the gear 10-of the pair .ofwheels 10, 11 loosely moves aboutthe shaft Sand thus rolls on the gear 14 of shaft 12.

The operation may be briefly outlined as follows: When the completely wound spools haveV been removed from the holders 1 and fresh spools placed thereon, the roll 5 is moved from the full:`

line position (Figs. 1 and .l 2) to the dotted line position 5a. As a consequence of this movement; and because-the distance between the two threads guided through each thread guide at the moment the rollis lstarted to move upwardly is greater than the distance apart of the spools to which'` the thread guide is allocated, the threads are automatically pressed against the rotating spools whichL are to be freshly wound, so that a new spinning Yperiod-may commence. It willbe understood that the spreading action ofthe thread guides only lasts during .the bottom part movement of thev roll? 5.` As soon as the angle between the part of the thread leaving the vspinning bath and running to the thread Aguide and the part of the threadleaving the thread guide and runningvtorthe roller is 'widened to about .180?th`e thread guide loses its spreading action but at that moment the threads* have already touched the running spools on thespool holders "andare taken over thereby.
