Definitions

  • This invention relates to a locking device, and more particularly to a centrifugal locking device for the cap of an up-twister machine.
  • Locking member 9 has a longitudinal bore 5 of approximately the same diameter considerable difficulty has heretofore been ex- 5 as the outside diameter of spindle l which passes perienced in retaining the up-twister cap on the through the bore 5. Near the lower end of lockspindle. Since the spindle must be operated at ing member 9 is a collaror flange 8 which is a high rate of speed the cap has a tendency to seated in an annular groove 6 in t n of fly off, subjecting operating personnel to a serious mounting sleeve I5..
  • Mounting sleev 15, which is hazard and causing possible damage to the cap 10 slidably engaged on spindle I is provided with and to the thread or filament wound on the spool a set screw it so that the position of locking or bobbin.
  • Several centrifugal locking devices dev 9 may be adjust d up r d wn on spindle which have been proposed in the past have proved I.
  • locking member 9 may be readily factory in operation inserted in mounting sleeve l5 before the sleeve
  • An object of this invention is to provide a relai placed on the Spindle by firmly pushing thereon tively inexpensive and simple device for locking with sufficient firmness to momentarily deform t cap f an up-twister t th spindle collar 9 of the member 9 and cause it to become
  • a further object is to provide a locking device Seated in groove 6.
  • y u able maleast one vertical slit so as to form two or more Berial Of a resilient nature s, for example, by sections which will be forced outwardly by cencasting or machining.
  • Locking member 9 is comtrifugal force.
  • a cap is provided which has a prised of a tubular stem portion 1 provided near sleeve member extending downwardly from the its lower end with a collar 8 and at s pper end hub and surrounding the elastic member.
  • a ove anging umbrella or mushroom lower end the sleeve member has an inwardly shapedeXtenSion I". At least one, and preferturned lip.

  • These slits ll pierce wardly by centrifugal force and the lower edges the entire wall of extension Ii) as well as the unof these sections tend to contact the lip of the derlying portion of tubular stem 1 in such a mansleeve when there is any tendency on the part of her as to make p b the locking mechanism the cap to fiy ofi".
  • the cap is effectively which will be explained more fully hereinafter.
  • FIG. 1 shows a sectional view of an up-twistis firmly attached to the hub portion [8 of cap er spindle equipped with one form of the locka by a pressure fit, and extends downwardly ing device of the invention; therefrom concentric to locking member 9.
