Definitions

  • the object of the invention is to produce a simple device for regulating the balance or hair springs of time-pieces, by which said springs may be quickly and easily inserted without injury to the springs, and by which the difference-in the running may be regulated within wide limits without elongating or cutting the springs, or without taking the movements out of the case; and the invention consists of certain details of construction, which will be more fully described hereinafter, and finally be pointed out in the claims.
  • Figure 1 represents a front view, partly in section, of my improved regulating device for the balance-springs of time-pieces.
  • Fig. 2 is a side view;
  • Fig. 3, a plan;
  • Figs. 4, 5, and 6 are details of parts of the regulating device.
  • A represents one of the supportingplates of a clock or other timepiece, through which passes a spindle, i, which is guided in a sleeve, t, of the plate A.
  • the front end of the spindle t which projects through the dial-plate, is made square for applying thereto a key for turning the spindle, and also a crank, 70, which turns with the spindle i, as will be described more fully hereinafter.
  • On the sleeve 43 is mounted a camplate, 9, the periphery of which correspondsto the spiral windings of the balance-sprin athat is to say, it has the same pitch as the latter.
  • a crank, 72 which carries in a socket a split pillar, e, the outer end of which is made of conical shape.
  • the pillar a can be turned on its axis in the socket of the crank h, and serves to clamp the balancespring a by means of a ring, f, that slides along the conical end of the pillar a, so as to compress the split ends of the same.
  • a ring, f that slides along the conical end of the pillar a, so as to compress the split ends of the same.
  • Herctofore a fixed pillar was used for holding the spring, which required the bending of the spring after each cutting off operation by means of a pair of pliers, so as to make it true and bring it back to the proper diameter for extending to the pillar.
  • the bending of the spring a and its detrimental effects is entirely avoided, as the pillar 0 can be turned in its socket and moved nearer to or farther away from the center of the spring a by simply turning the crank h.
  • the position of the spring a in a plane vertical with the axis of the balance-wheel is regulated by shifting the spring backward or forward between the split portion of the pillar e, and securing it then in position by the clamping-ring f.
  • cam-plate g When the position of the spring has been adjusted with reference to the escapcment-lever, and the escapement should still be out of boat, the cam-plate g is turned to the right or left, as required, after which the cam-plate g is se cured in position by a setscrew, m, that passes through the plate A, as shown in Figs. 2 and 3.
  • crank, k, and spring 1? are made use of.
  • the crank it is keyed to the rear end of the spindle t, back of the cam-plate g, and turned by a key applied to the square front end of the spindle.
  • the bent spring (1 is attached to the crank. 75, and provided at its outer end with a slot, p, and alinger, g, which latter slides along the circumference of the cam-plate g, and guides thereby the slot 1) in the same line.
  • the exterior winding of the balance-spring a is passed through the slot p of the spring (I.
  • the camplate 9 is provided with two stops, at and 0, which prevent the crank it from being turned too far by the spindle i.
