Definitions

  • JOSEPH BRUN OF ⁇ CBATJ'X DE FOND, SWITZERLAND, ASSIGOR OF ONE-HALF TO j CHARLES F. DEPOLLIER, OF BROOKLYN, NEW YORK.
  • This invention has for its object to ⁇ provide improved rmeans whereby the pivot of the balance wheel of a watch and particularly the cap jewels which form the endthrust bearings of the pivot are protected against injury due to shocks. It has been proposed heretofore to accomplish this purpose by cushioning or yieldingly supporting the cap jewels so that they yield slightly with sudden endwise movements of the pivot and thereby avoid being broken by a hammer like blow of the pivot.
  • the devices heretofore produced for this purpose have not come into general use, probably because they have not been well adapted for the purpose, the spring support being cumbersome or permitting too much movement of the jewel or, on the other hand, not beingr sufficiently delicate to prevent breakage of the fragile jewel.
  • the present invention there is provided for the cap.
  • the jewel an improved yielding supportwhich is readily applied, involves the use of no long, flat spring, does not permit undue movement of the jewel, and presses the jewel toward the ⁇ pivot with such delicacy that the jewel can yield with any endwise movement of the pivot sufficiently to take up the shock and prevent breakage.
  • the jewel is supported by a minute star-like or spider-like Hat spring, the ends of the arms of which are received in an annulus or frame which is itself secured to the cock or other plate in which the pivot bearing is mounted.
  • Figure 1 is a top view of a portion of a watch ⁇ movement, showing particularly the mounting of the balance wheel in the cock.
  • Figure 2 is a detail view, on a larger scale, in vertical central section, showing the staff or pivot, the jewels at each end, and the supporting devices therefor.
  • Figure 3 is a detail view of the spring
  • Figure is a detail view of the cap jewel setting shown in Figure 2. i
  • Figure 5 is a detail view4 in elevation, partly broken away, of the annulus or frame at the lower end of the staff as shown in Figure 2.
  • the staff (L of the balance wheel b of a ⁇ watch may be mounted substantially as usual in the cock c and the opposite plate d of the movement frame.
  • the staff or pivot a is received in a ⁇ perforated jewel e, which may be secured in a ring f which in turn is secured in the cock c or frame plate d.
  • a cap jewel g which forms an end-thrust bearing for the staff or pivot.
  • this cap jewel is shown as mounted in a cap jewel setting z. provided withacentral boss h,although such setting might be dispensed with if desired.
  • the boss 71 is shown as mounted in a cap jewel setting z. provided withacentral boss h,although such setting might be dispensed with if desired.
  • annulus or frame k3 which receives the ends ⁇ of the arms of the retainer z' in its undercut groove lc', is shown as threaded into its seat in the plate d so that adjustment of the cap jewel toward and from the staff a can be effected if desired, a screw It* being provided for the purpose of securing the annulus or frame 7c3 in adjusted position.
  • the resilience of the delicate arms i2 of the spring retainer or seat z' holds the cap jewel lightly toward or in contact with the end of the staff and yield sufficiently to cushion the jewel against sudden endwise movement ofv the pivot and thereby prevent the breaking of the fragile jewel which often occurs when the jewel is supported rigidly.
  • the jewel is so supported that it does not have undue movement.
  • the spring retainer is seated in the annulus or frame l: or las as the case may be by slightly cupping the retainer and allowing the ends of the arms to spring; into the undereut groove la.
  • a jeweled bearing for wntelres, ete. comprising an ennulus adapted to be secured to :L l'rznne plete7 and e jewel-retainer haring radiating erlns engaged with the unnulus, and adapted to support e een jewel.
  • a jeweled bearing for Watches, ete comprising an ennulus adapted to be secured to e treme plate, :L jewel-retainer having n central aperture end radiating arms engaged with the ⁇ annulus and e jewel settingr supported by the retainer and lia-ving n, central boss to engage the aperture of the retainer.
