The object of this invention is to provide a thumb screw 19 which by means of collars 20 feeler mechanism for looms of the so-called thereon it swiveled in the wall 14 and is side swipe class whichwill not perform its tapped'into a stud 21 pivoted in the lever. side-swipe movement prematurely, as due to On the carrier which is thus formed by the the pointed or conical end instead of the cyslide 12 and'lever 17 is fulcrumed a pair of 5 lindrical part of the wound package being fecler-levers 22-23, these being also arpresented thereto, and which, instead of reranged in a horizontal plane, or more specifiquiring a special or extra-formed mass or' Cally, a plane cutting the filling package. bunch of windings to be provided as a re- One of these feeler-levers is fulcrumed on the r serve which will remain definitely attached to lever 17, as at 24; the other (22) is fulcrumed the core of the package, is adapted to perform on the pivot 18 of said lever.

:. Thereis a' tendency for-such skidding or slippage to occur'when the conical end of the package, as occasionally happensyregisters with the more advanced end of feelerf lever 28 but this'tendency is prevented from becoming an actuality, so thatprematr re actuation ofsaidactuatedmechanism is avoidv ed, by the feeler-leve'rgQQ at that time obtaining a non-skid contact with the cylindrical partof thepackage;
