Definitions

  • the improved spindle tha constitutes the object of the present invention, the effects of the vibrations are completely eliminated and, at the same time, the construction is simplified, the cost of the spindle is reduced, and superior conditions with respect to lubrication and refrigeration are obtained.
  • Fig. 1 is a side elevational view of the spindle
  • Fig. 2 is a longitudinal section thereof.
  • the footstep bearing 1, by which the lower end 2 of the shaft 3 of the spindle is supported and guided, is an independent element without any rigid connection with the cylindrical bearing 4 of the proper shaft 3, and which hangs floatingly by its upper portion, so that it may be able to adopt various inclinations in a way comparable to a pendulum.
  • the lower bearing 1 is constituted by a kind of thimble or cup hanging by means of a rim 5 around its mouth on a corresponding inner seat 6 of the tube or supporting casing 7 of the spindle, the said rim being pressed against its seat by a helical spring 8 held in position by a corresponding stop which may be formed by an open ring 9 engaged in an inner groove of the tube or supporting casing 7.
  • the footstep bearing 1 is of a conical sh ape both enteriorly and inteniorly and forms in its base the footstep 10 against which and against a circle or extremely reduced zone of the inner conicity of the thimble or cup comes to rest the lower end 2 of the spindle shaft.
  • the guides and supporting means of the spindle shaft 3 are constituted by the said lower pendular bearing 1 and by a cylindrical bearing 4, combined or not with rollers and secured to the tube or supportingcasing 7 ofthe spindle.
  • the tube or supporting casing 7 of the spindle is made up of stamped material, preferably steel plate, and forms corresponding projections, foldings and doublings to give it the necessary resistance and for permitting the mounting of the spindle on the spindle bearing plate of the machine.
  • the general shape of the stamped spindle casing is exteriorly similar to the typical shape of conventional spindles, so that it may be fitted to the machine in the usual way.
  • the spindle is not provided with the typical movable inner tube, so that there is a great inner space 11 which serves as a chamber for lubrication and refrigeration purposes, with direct radiation wall formed by the casing 7.
  • the wharve or pulley 12 is also made of stamped material, steel plate, as also the lower bearing 1.
  • the retaining element of the spindle shaft 3 and the wharve or pulley 12 is constituted by a doubled wire hook 13 Which forms two feet 14 14' that tend to separate elastically one from the other and whose extreme positions, corresponding to the lowered and elevated positions of the hook, are made firm by the tendency of the feet to occupy the most separated points of two circular holes 15-45, into which they are introduced, provided for their hinging in the tube or supporting casing 7 of the spindle, retaining or permitting the extraction of the spindle shaft 3 and the wharve 12.
  • the lower bearing 1 is flooded with lubricating oil that passes through a hole 16 provided in its wall. This oil being interposed between the rim 5 and the seat 6 acts at the same time as a buffer or shock absorber.
  • the improved spindle as described gives important advantages over the conventional constructions.
  • the flexible mounting of the spindle shaft 3 with rigid connection only through the bearings 4 allows its lower end 2, supported by the movable pendular bearing 1, to adapt itself to lateral movements which may aflect the spindle as a consequence of eccentricities of masses, so that all vibrations disppear.
  • the lower pendular bearing avoids from the beginning of the working of the spindle all vibrations, even in difficult cases of very heavy or defective bobbins. This means an increase in production and an improvement in the quality of the thread.
  • the total weight of the spindle is on the other hand about 40 percent lower than that of conventional spindles, which is important under various aspects. Finally, the cost of the improved spindle is only about 50 percent of that of conventional spindles.
  • a collar bearing for said shaft in said casing, a collar bearing for said shaft, a fioatingly arranged footstep bearing for the lower end of said shaft, said footstep bearing comprising a conical cup portion: and a rim portion, an annular shoulder formed by the inner wall of said casing and providing a seat supporting said rim portion, said casing having an annular groove in the inner wall thereof, a ring in said groove, and a helical spring in said casing between said [ring and said rim portion pressing said rim portion against said seat.
