CLOCK-PENDULUM.

SPECIFICATION forming part of Letters Patent NO. 404,997, dated June 11, 1889.

Application iiled October 10, 1888. Serial No. 287,778. (No model.) Patented in Germany February l5, 1888, No. 44,446.

T all whom it may concern:

Be it known that I, JOSEPH \VERNER,f the city of Dresden, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in the Means for Suspension of Pendulums of Clocks, (for which I have obtained a patent in Germany, dated February l5, 1888, No. 44,446,) of which the following is a speciiicaticn, reference being had to the accompanying drawings.

It is an essential point in clocks to construct -the mechanical parts ot the clockwork in such a manner that they'not only work with the least possible friction, but also so that bearings causing friction shall be avoided as much as possible, in order that variations in the resistance of such frictional parts will be reduced as far as possible and the clock' may work regularly. The defects mentioned will mostly occur in the means of suspending the pendulum. Such defects may be in some degree counterbalanced by increasing` the weight; but the irregularities which result from'the above-mentioned defects in the bearings cannot be obviated thereby. Now, in order to obtain a suspension of the pendulum, causing the least possible friction, but at the same time allowing an exact adjustment of the hooking and of the stroke or swing of the pendulum, I construct and combine the suspension devices, as hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 represents a back view of a clock having my invention applied to it. Fig. 2 represents a central vertical section of the same. Fig. 3 is a view corresponding with Fig. 2, but on a larger scale, representing only the parts included in my improvement. Fig. 4 is a top View of the anchor-spindle. Fig. 5 is a view at right angles to Fig. 8, partly in section in the line 0 0, of the escape-wheel and anchor, representing, also in section, the means of supporting the anchorspindle. Fig. 6 represents a horizontal section in the line 5c :t of Figs. 8 and 5. Fig. 7 represents a horizontal section in the line y y of Figs. 3 and 5.

Similar letters of reference designate corresponding parts in the several figures.

In the upper part of the clock-work I arrange a carrier A, (represented as a horizontal ban) for carrying the two swing-springs or flexible suspension parts D, which are connected together bythe anchor-spindle B. On the one end of said anchor-spindle B there is a head l), provided with the carrying-pin a, on which the pendulum is suspended or hooked.

The carrier A is represented as adjustable 6o in height by means of a screw d in the top of the clock-case, so as to be able to exactly regulate the engagement of the anchor E into the balance-wheel or escapement-wheel. Furthermore, a guiding-pin c and a setscrew f are applied between the carrier and the top of the case, so that no sidewise shifting or displacement of the carrier A may take place. The hook of the pendulum-rod P is not affixed to the latter, but to the ad- 7o justing mechanism, which is of peculiar construction, its principal part consisting of the double-armed lever F, which may be turned or moved on the fulcrum or pin g, provided on the rod P of the pendulum. This pin g constitutes a pivotal suspension of the pendulum from the lever F. The adjustment of said lever F is effected by means of the horizontal screw 71, capable of turning in bearings afixed to the pendulum-stem, said screw 8o carrying a nut t, on which is a pin 7c, which enters between two pins or a forkl on the lower end of the lever F. By turning the screw h the nut t is shifted, and by means of the pins or fork Z the lever F and the 85.

pendulum are laterally adjusted the one to the other, and t-he pendulum-rod is adjusted relatively to the center of suspension at a m to one side or the other, as may be rcquired.

Vhat I claim as my invention is- The combination, with the vertically-adjustablecarrier A, the anchor-spindle B, and the suspension-springs D, suspending the said spindle from said carrier, of the adjust- 95 ing-lever F, suspended at its upper end from the @nehm-Spindle, the pendulum pivotully suspended from seid level.` between the ends of the laitier, and also connected with the lutter at the lower end thereof, and the adjusting-serew 7l, applied al: the last-mentioned eonneebion 'foi the lateral adjustment of Jelle pendulum, Substantially as herein described.

In testimony that I claim the 'foregoing' as my invention I have signed my nume in presi ence of two subscribing; witnesses.

JOSEPH WTERNER.
