Definitions

  • the oscillating 'set of watches comprises a staff on the shoulders of which are fitted the balance, the escapement roller, and the collet adapted to render the inner extremity of the balance-spring integral with the set.
  • the staff is provided with pivots, by means of which it can oscillate in bearings of the watch-frame.
  • the object of the present invention is precisely to provide a method of making an oscillating set, in which the centering and alignment achieved are better than what has been obtained to this day.
  • the oscillating set for clock work-movement comprises a cylindrical staff, provided with pivots, a collet for fixing the balance-spring, a bushing provided with two protrusions forming the smaller and the main escapement rollers, and with a collar which is adapted to receive the balance.
  • Said oscillating set is characterized in that the bore of said bushing is of reduced cross-section in front of the collar, in order that, when the cylindrical staff is force-fitted into the bore of the bushing, the diameter of the collar is caused to increase, whereby the balance is made integral with said bushing,.
  • FIGURES 1 and 2 are a general view and a detail view respectively in cross-section, of a first form of embodi-. ment, and
  • FIGURES is a vertical section of a second form of embodiment.
  • the oscillating set according to FIG. 1 comprises, on the one hand, a cylindrical staff 1 provided with pivots 2, and on the other hand, a bushing 3 forming the escapement roller and provided with two protrusions 3a and 3b acting as the smaller and the main rollers respectively, a collar 3c on which is placed the balance 4, and the collet 5 adapted to retain the extremity of the balancespring (not shown).
  • Bushing 3 (FIG. 2) has a bore 8, the cross-section of which is reduced at 8a, in front of the collar 30.
  • Said collar has a diameter slightly smaller than that of the hole made in the balance-arm, so that it can easily pene-, trate into said hole.
  • An appropriate choice of the diameters permits slight blocking of the cylindrical staff 1 with respect to bore 8.
  • the balance for 4 is first placed on the collar 3c, then the staff 1 is driven into bore 8 in the direction of arrow 9.. Whenever that staff penetrates into portion 8a of smaller cross-section, it will distort that portion, thereby increasing the diameter of collar 30 which is then squeezed in the balance bore.
  • the collet provided with the balancespring is then driven on staff 1. Said collet will rest, by its lower face 511, on the upper face 3c of the bushing.
  • the set once its elements are mounted, keeps a perfect concentricity since none of these elements has undergone stresses likely to cause a collapse or a distortion.
  • the assembly thus achieved has, as regards the centering and the alignment of its elements, a precision never achieved with the methods or devices known to this day.
  • the oscillating set shown in FIGv 3 comprises, on the one hand, a pivoting cylindrical staff 1, and, on the other hand, a bushing forming the escapement rollers and having two protrusions acting as the smaller and the main rollers respectively, a collar on which is placed the balance 4, and a collet 5 adapted to retain the extremity of the balance-spring (not shown).
  • the impulse pin 6 of the main roller is fitted in an opening of the protrusion 3b, whereas protrusion 3a is, provided with a notch 7, necessary for operating the lever escapement Prior to the mounting, the staff is of a diameter slightly greater than the bore of the bushing, and the lower diameter of the hole made in the balance-arm is slightly smaller than the diameter of the collar.
  • the mounting is achieved by forcing the balance on the collar, then by driving the staff in the bushing.
  • the collet bearing the balance-spring is then drive in the staff, on which it is retained by the collar.
  • the bushing is thus submitted to opposed internal and external pressures which hold it tightly.
  • the method of the invention is rapid and can easily be effected by automatic means.
  • Method for making an oscillating set for a clock workmovement comprising the steps of providing a bushing having at one end thereof a collar and an axial bore the diameter of which is reduced in front of said collar near,
