DEVICE FOR ADJU-STING VCLOCK-PE'NDULUMS.
SPECIFICATION forming part of Letters Patent No'. 278,781, dated June 5, 1883.
` Application fili-.a october 31, 1882. (No masi.)
To aZZ whom t may concern:
Be it known that I, MARKS C. Davis, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Clocks, of which the following is a specification.
The object of my said invention is to provide a means of so adjusting the pendulums of clocks as to restore the regularity of the beat when the same becomes irregular from any cause, as from placing the clock on an uneven surface, as a shelf not level. rlhis object is accomplished by placing the stud to which the pendulum is suspended upon a sliding or movable strip or bar and attaching thereto a screw, rack and pinion, lever, or some similar mechanism whereby it can be moved back and forth, as will be hereinafter more particularly described.
Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a front elevation of a clock -with the dial-plate removed and some portions broken away, embodying my invention Fig. 2, a similar view of an alternate construction; Fig. 3, a horizontal sectional view of so much thereof as relates immediately to said invention, looking downwardly from the dotted line z z in Fig. l; Fig. 4, a similar view, looking downwardly from the dotted line y y in Fig. 2; and Fig. 5, avertical sectional view, looking to the left from the dotted line x af.
In said drawings, the portions marked A represent the clock-frame; B, the movementframe 5 C, the pendulum-rod; D, the. vergewire; E, the sliding bar bearing the stud on which the pendulum-wire is hung; F, a screw :for operating said bar, and G a clock-key.
The sev-eral parts, A, B, C, D, and G are or may be of any usual or approved form or construction. The stud c, upon which the pendulum C is hung, is, however, set in the sliding bar E and moves therewith. The frame B should have slides b I) attached thereto as supports for the sliding bar E.
The bar E issecured to the frame B by the slides ZJ b and the screw c', or in some other suitable manner, and is adapted to-move transversely across said frame and carry with it the stud c, and consequently the p endulum-rod, which is attached to said stud.
The screw F'passes through a projection, c, on the bar E, and extends out through the side of the clock-frame A, in which is a bearing int-o which said rod is shouldered, as shown most plainly in Fig. 3, wherebylsaid screw is held in position and is enabled to force the bar E back and forth, and thus vary the position of the stud c and the pendulum C. rlhe screw F may be driven by an ordinary clock-key, G, or otherwise.
Instead of the screw above described, a rack and pinion may be used, as shown in Figs. 2 and 4, with the same result, in which case the clock-key G could be inserted through a hol'e in the dial, similar to the ordinary holes through which it is inserted to wind the clock, instead of being placed upon the end of the screw at the side, as shown in the other figures. The mechanical operation of these devices being simple and easily understood, and said devices being among the most common forms of mechanism, need no detailed description. I t is also obvious that various forms of lever and other mechanism might be employed instead of a screw or rack and pinion to effect the move- VThe clock being provided with my invention,
upon being placed upon a surface not level, thus disturbing the proper relations between the verge and the pendulum, and thereby throwing the clock out of beat, need not be leveledup by the usual slow and tiresome pro-' cess; but by moving the stud c by any of the mechanism shown, or any equivalent thereof, as described, the relation can be easily and quickly restored, and the beat thus made as perfect as if the surface upon which the clock rested were perfectly level.
I am aware that a swinging device has been employed for a similar purpose, and I do not therefore claim all means whereby the described result may be effected. Iam not aware, however, that a horizontally-sliding bar actuated by mechanism adapted to move it to a certain point and there hold it has before been used for this purpose, and such a device has manifest advantages over that previously in- IOO vented by reason of its greater certainty of operation.
y Having thus 'fully described my said invention what I claim as new, and desire to secure by I etters Patent, is
l. In combination with the pendulum of a eloek-movement7 a horizontal bar having fixed guides and carrying the stud to which Jche pendulum is hung, and means for adjusting said bar, substantially as shown and described.
2. In combination with the pendulum of a clock, a horizontal bar sliding in suitable guides and carrying the stud to which the pendulum is hung, and Jshe adjusting-screw F, having bearing in Jche frame, substantiallyY as and for Jche purposes described.
In Witness whereof I have hereunto setmy hand and seal, at Indianapolis, Indiana, this 27th day of October, A. D. 1882.
