Definitions

  • ABSTRACT A pendulum clock of the weighted rope end-type, constructed so as to be fitted with a commerically mass-produced clockwork, and which will run dependably and in a frictionless manner upon the simple and inexpensive assembly thereof.
  • the clock includes a lever which comprises a pendulum-type wire having an end remote from an escapement shaft, bent in parallel with the escapement shaft and extending into a pendulum slot, and in which the pendulum base is pivotably suspended from a wire, or the like, by means of ears or loops fastened to its upper surface.
  • the pendulum base which extends parallel to the escapement shaft is here, in a desirable construction, formed as a shaft which is journalled in suitable pivots.
  • an object of the present invention to provide an improved pendulum clock of the weighted rope end-type constructed pursuant to the above-mentioned art, which may be fitted with a commercially mass-produced clockwork, and which will run dependably and in a frictionless manner upon the simple and inexpensive assembly thereof.
  • the lever comprises a pendulum-type wire having an end remote from the escapement shaft bent in parallel with the escapement shaft and extending into the pendulum slot, and in which the pendulum base is pivotably suspended from a wire, or the like, by means of ears or loops fastened to its upper surface.
  • This construction in a simple manner, allows the pendulum-type wire to couple a standard commercial clockwork with the slot of the pendulum.
  • the suspension of the pendulum base on a wire or the like by means of ears is not only a simple and inexpensive construction, but also provides the further advantage of considerable freedom from friction, inasmuch as at the site of pendulum support there is provided a rolling or the invention relates to a pendulum rocking movement in lieu of a force-retardant pivotal friction.
  • the pendulum-type wire is fused into the escapement shaft, in effect, fastened to the escapement shaft through a spot weld connection.
  • a counterweight which is preferably located at the end of the pendulum base which is opposite to the pendulum.
  • this counterweight is integrally connected with the pendulum base.
  • the pendulum base together with the counterweight and the ears as an integral component formed of plastic material, or the like.
  • FIG. 1 is a front elevational view of a portion of the pendulum clock of the type described, showing the invention.
  • FIG. 2 is a side elevational view of the constructional elements illustrated in FIG. 1.
  • An oscillating pendulum 36 of the type described located in front of the clock dial not shown) is provided with a pendulum weight 38, and includes at its upper end a pendulum base 34 extending parallel to the escapement shaft 14 and having upwardly looped ears 30 and 32 which are hooked into the yoke 28.
  • the ears 30 and 32, together with the wire-constructed yoke 28, form the support for the pendulum 36.
  • the former At the end of the pendulum base 34 proximate the support frame 10, the former includes a downwardly bent counterweight 40 which, in the described exemplary embodiment, is integrally connected with the pendulum base.
  • the ears 30 and 32 may either be bent, as illustrated, from wire and then fastened to the pendulum base, or be integrally formed with the pendulum base.
  • an attachment 42 with a slot 44, into which extends the upper end 24 of the pendulum-type wire 22. In this manner, the movement of the escapement shaft 14 is transmitted to the pendulum base 34, and thereby to the pendulum 36.
  • a pendulum clock having a weighted oscillating pendulum supported on a stationary frame; an escapement shaft; and a lever connected to said escapement shaft, said lever having a segment engaged in a slot in a portion of the pendulum extending in parallel with said escapement shaft so as to form a connection with said pendulum, the improvement comprising; said lever being a pendulum-type wire, said wire having a bent end portion remote from said escapement shaft and extending parallel therewith, said end portion being engaged in the pendulum slot; ear means being formed on the upper surface of said pendulum base; and support means on the upper end of said frame, said support 4 means being engaged by said ears for pivotable suspension thereon of said pendulum.
  • An improvement as claimed in claim 1, comprising a counterweight being provided on one end ofsaid pendulum base opposite to the end supporting said pendulum.
