NITED STATES PATENT Finca,
HENRY J. DAVIES, OF BROOKLYN, NEW YORK.
PENDULUlVI-*INDICATOR FOR CLOCKS.
SPECIFICATION forming part of Letters Patent No. 248,716, dated October 25, 1881.
Application tiled April 14, 1881.
To all whom it may concern Be it known that I, HENRY J. Davies, of Brooklyn, in the county ot' Kings and State ot' New York, have invented a certain new and vImproved Pendulum-Indicator for Clocks, of
which the following is a specitication.
The pendulum-clocks which are most popular at the present time are those in which the pendulum is not visible from the front otl the caseWhenthelatterisclosed. It cannotreadily be ascertained, however, whether such a clock is going without opening the case or listening for the beat ot' the clock; and the object ot' my invention is to enable one to tell whether such clock is going by simply glancing at the dial.
To this end theinvention consists in the combination, in a clock, with the crutch-wire, pendulum-rod, or other part moving or vibrating in unison with the pendulum, and a dial having in it a slot or opening, of a pin or arm attached to said vibrating part and projecting through the slot or opening inthe dial, and an indicator attached to said pin or arm in front of the dial and moving with the pendulum, thus enabling a person to readily ascertain whether the clock is going by simply glancing at the dial. The indicator may be attached to said pin or arm, so that it may be readily detached therefrom, thus aii'ordin g provision for readily substituting for one indicator another of diiterent form.
In the accompanying drawings, Figure 1 rcpresents a front view of a dial and pendulum having my indicator applied thereto. Fig. 2 represents a section on the dotted line mw, Fig. 1; and Fig. 3 represents ahorizontal section ot' a portion of the dial, crutch-wire,pend alum-rod, and indicator.
Similar letters ot' reference designate corresponding parts in all the iigures.
A A designates a portion of one of the plates of a clock-movement, and B designates the dial. C designates the pendulum-bol), and D the pendulum-rod suspended from the stud a in the usual manner. E designates the escapement-lever, and Fv designates the crutchwire extending therefrom and serving to vibrate the pendulum-rod and pendulum in the usual way.
Attached to the crutch-wire F, and projecting forward therefrom through a slot or elongated hole, b, in the dial B, is a pin or arm, c, and at the front end of said pin or arm andin front of the dial is attached an indicator, d,
(No model.)
which, as here represented, consists of a star, but which might be made in any form to suit the fancy.
Theindicator d might be permanently attached to the pin or arm c by solder or otherwise; but it may be attached so that it may be readily removed, when desired, and another indicator of different form substituted therefor. In the present example ot' my invention the indicator has a socket, c, projecting from its inner face or back, and adapted to iit over or receive within it the pin or arm o. As the crutch-wire F moves back and forth the pin or arm c and the indicator el move with it, and the slot or opening in the dial should be of sufficient length to prevent the pin or arm cfrom striking at the ends ot' the slot or opening.
Where the pendulum is adjustable up and down on the pendulum-rod to regulate the clock, the pin or arm c might be attached to the pendulum-rod; but where the pendulumrod is raised or lowered to regulate the clock, if the pin or arm were attached to the pendulum-rod the opening in the dial would necessarily have to be large enough to admit ot' the pin or arm moving vertically therein.
By my invention I provide in a very simple manner for ascertaining, by glancing at the dial, whether a clock is going.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a clock, the combination, with a part moving or vibrating in unison with the'pendulum, and a dial having in it a slot or elongated opening, ot' apin or arm attached to said vibrating part and projecting through the slot or opening in the dial, and an indicator attached to said pin or arm in front ot' the dial, substantially as and for the purpose specitied.
2. In a clock, the combination, with apart moving or vibrating in unison with the pendulum, and a dial having in ita slot or opening, of a pin or arm attached to said vibrating part and projecting through the slot or opening in the dial, and an indicator detachably secured to said pin or arm in front ot' the dial, whereby provision is att'orded for readily substituting one indicator for another ot' dit'- ferent form, substantially as and for the purpose specied.
HENRY J. DAVIES.
