UNITED STATES PATENT OFFICE.
\VILLIAM S. SCALES, OF EYERET", ASSIGNOR OF Tll'O ll'llRDS TO JOSEPH ll. CLARK, OF QUINCY, AND .lOlIY B. HFMPHREY, OF BOSTON, MASSACHU- SETTFR SECONDARY ELECTRIC CLOCK.
SPECIFICATION forming part of Letters Patent No. 448,999, dated March 24, 1891.
Application filed October 20, 1890- Serial No. 868,672. (No model.)
To (ti/ whom it 'HMi/j/ calmer/1 Be it known that 1, WILLIAM S. SCALES, of vEverett, county of llliddlesex, State of Massazhusetts, have invented an Improvement in Electric Clocks, of which the following description, in connection with the accompany ing drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object to improve J the construction of electric clocks such as shown in my application, Serial No. 359,304, filed July 19, 1890.
In accordance with this invention any suitable train may be employed, and a step-by-step I5 driving mechanism is provided, consisting of a ratchet-wheel secured to one of the shafts of the train and a pawl. As herein represented a single pawl is used which is attached to or moved by the propeller. The propeller is moved in one direction to accumulate a force whichis to be imparted to the pendulum or other regulating member by means of the armature of an electro-magnet and is held in such elevated position until the circuit of the 5 electro-magnet is brolzemwhen the armature retracts and the entire weight of the propeller is given to the pendulum. The circuit of the eleetroanagnet is broken by the pendulum just prior to arriving at one limit of motion. The propeller is so arranged that if the armature fails to move it or to even move it sufficiently to in turn move the ratchet wheel the pendulum. will accomplish such result.
Figure 1 shows in front elevation an elec tric elocl; embodying this invention, and Fig. 2 a detail of the operating parts in a different position.
The main framework. A, the driviug-train consisting of the ratchet toothed wheel a, se-
cured to a shaft a, bearing a pinion aiwhich meshes with a toothed wheel of, secured to a shaft to, carrying the pinion a, which ongages a toothed wheel a, secured to a shaft 5 a, carrying the minute-hand a and the ordinary mechanism for driving the hour-hand a, the electro-magnet b, and its armature Z), pivoted at '0 and provided with a retractile weight if", or it may be a spring, are all substantially as in the application referred to. The driving mechanism herein shown is speciiically different, however, from that shown in the said application, it consisting of a pawl I), attached to the propeller (Z, pivot-ed at (Z and carrying a weight (Z and an arm, as Z), attached to the armature for moving said propeller in one direction to in turn move the ratchet-wheel forward step by step, and the arm, as 0 attached to or moved by the pendulum for also moving said propeller in case the arm 1)" fails. The pendulum, as herein shown, consists of the bob 0 and rod c, to which it is attached. In lieu of the arm b" the armature itself may subserve the purpose.
The circuit-closer of the electro-magnet consists of a flat spring, or it may be a springacting arm 2, attached to the propeller, and a contact 3, carried by the arm Z)".
The operation of the parts is as follows: Supposing the pendulum to be swung in the 0 direction of the arrow it, the short arm c will bear against the spring 2, pressing it against the propeller (Z, thereby moving the propeller (Z in the direction of the arrow 5 so far as to cause the pawl to move the ratchet-wheel a. ahead the distance of one tooth. As the pendulum returns, the propeller (Z follows it until the spring 9 strikes the contact 3 on the arm Z), at which time the circuit of the electromagnet b is closed and the armature is at once attracted, moving the propeller (Z again in the direction of the arrow 5 and moving the ratchet-wheel a ahead another tooth while the pendulum c is completing its movement in a direction opposite the arrow 4. The propeller will be held in its elevated position with the armature attracted until the pendulum returns in the direction of the arrow l and the short arm 0 strikes the spring 2, moving it away from the contact 3, and 9:) thereby opening the circuit of the electromagnet b,when, the armature immediately retracting, the weight of the propeller falls on the arm 0 and is hence imparted to the pendulum. This operation is continued, the pro- 5 peller being lifted by the attracting armature to accumulate a force to be given to the pond ulum, and when the propeller is so lifted the ratchet-wheel is moved so that forthe accom I to actuate said pawl, substantially as de plishment of the work which it is desired to be done the electro-magnet is depended upon; yet if the armature should fail for one or more impulses to accomplish these results the arm 0 actingin a manner as above described in starting the clock, would move the propeller and ratchet-wheel. The spring 2 is quite weak, and whenacted upon by the arm b will bear against the propeller d to move it, and the pawl b is so shaped as to be disengaged from the teeth of the ratchet-wheel when it has moved said wheel forward a tooth, so that as the arm 0 comes forward and strikes the propeller it may move it sufficiently to break the contact 2 3 and at the same time not move the ratchet-wheel, the propeller being shown in this position in Fig. 2.
1. In an electric clock, a train and a step-bystep driving mechanism therefor, consisting of a ratchet-whee1 and pawl, combined with an electro-magnet and its armature and a regulating member for the clock, both the armature and regulating member being adapted scribed.
2. In an electric clock, a train, a regulating member therefor, an electro-magnet and its armature, and a step-by-step driving mechanism for the train, consisting of a ratchetwheel and pawl, combined with a propeller for the regulating member which carries said pawl, substantially as described.
3. In an electric clock, a train,a regulating member therefor, an electro-magnet and its armature, and a step-by-step driving mechanism for the train, combined with a propeller for v the regulating member and a circuit-closer, one member of which is operated by the propeller and the other member by the armature, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
