'In the-drawings, referringv particularly to Figs. 1,-2 and, 3,8 is a thread carrier preferably consisting of a rectangular supper-t9 electric circuit;conections for the carrier,

comparatively straight line, 'but i V[upon the 'breakage of "saidlthre'ad said feeler therethrough7 In addition to the trouble isometimes caused'by the breaking ofv the thread, there is often a great deal of trouble caused by the .thread on some'of the carriers being spent, whereupon if not detected immediately, a defect will appear in the work bein gformed on the machine vof which said carrier is a part. To overcome thisy diiliculty a second 4detector 46 is provided consisting of a rod 47 'which is pivoted in the ends 32 and 33 of the support 9 and/is also provided with a feeler 48 which is adapted to engage the outer surface of said thread-mass andis yieldingly pressed thereagainst by a torsional spring 49 which encircles the rocl 47. The feelerv 48 is preferably slightly'longer than the distance between the outer surface of the spindle 10 andthe axis of the rrlv 47; Thus it .will be seen that said feeler will be prevented from being swung upwardly and beyond theplane connecting the axis of said rod-and the Vaxis of said spindle. But in order to permit said feeler toipass-by said spindle and across said plane, anannular- Lgroove 50 is formed in the spindle 10 of sufficient depth to permit a. ,of thread to be wound 'therein and still permit said. feeler tojswing u wardly. therethrough.

. The-general operation'of the device is as follows: The spindle 1() having' a suitable amount of thread wound thereon is placed -upon the support 9 in thebearing 11,I the *tension feelerf and detector feeler`46 be-` ing forceddownwardly against the actions .of their "respective springs and the disconnecting the terminals 18`and- 21. `The vshield?? through -the thread-guide 3Ql to the adjacent to the -endf32 of said support isa'v to.l engage the' plurality of coursescontainedinsaid an'nuplurality of lcoils notarse ,io-int ivneie the noih is termed and upon l is held 1n disconnected relation'to said terd airing said thread taut, said eeler 39 is v swung downwardly aga-inst the action o'li the 'spring whe the end ot the terminal 18 and the terreby the connection bet-Ween minal QG is broken. thereby opening the elec tric circuit l? and deiiergizing the magnet Li?. llvhen this operation has been `performed: upon each ofthe carriers contained in the machine, said machine is ready to be started `which may be done by any suitable device controlled by the electro-magnet 43 when it is desired that a thread breakage or a spent thread is to stop the machine.

lt' during the operation ot said machine' the thread 25 should brealr,l the feeler 3.9 on the detector is released whereupon said detector is forced upwardly to the position illustrated in Fig. 5, when the armA 41 will.

engage the terminal 18 thereby connecting said terminal with the terminal l2 upon which said arm is -pivoted, and close the electric circuit 17 and ener izing the magnet liilhen the thread on the spindle l is nearly spent, that is, With the exception ot several courses of thread which are contained in the annular Igroove 50, the teeler atl-is. released and allowed to swing up vvardly upon its pivots until the pin l engages the bracket 19 whereupon the terniinal l2 .is connected vvith the terminal 18 and thus the electric circuit i7 will be closed` whereby the result her'einbetore stated will be accomplished.

lt willV be obvious that this invention may be adapted to any device or machine eniploying thread carriers or thread-masses, and turthermore the specitic construction oit the device Twould not necessarily have to be carried out as herein shown and described, lmany variations and changes might be ade Without departing from the spirit of the invention or sacrii'icing the advantages obtained thereby.
