AUTOMATIC CIRCUIT-BREAKER FOR SECONDARY BATTERIES.

SPECIFICATION forming part of Letters Patent No. 252,004, dated January 3, 1882.

Application filed September 19, 1881. (No model.)

To all whom tt may concern:

Be it known that we, JAMES A. MALONEY and FRANZ BURGER, of the city of Washington, in the District of Columbia, have invented a new and useful Improvement in Automatic Circuit-Breakers for Secondary Batteries; and we do hereby declare the following to be a full, clear, and exact description of the same, when taken in connection with the accompanying :0 drawing and the letters of reference marked thereon.

In the drawing we have shown our improvementin circuit with an electrophore light and dynamo-electric machine, the light being on a branch circuit from the electrophore.

A represents a stationary magnet having the armature B, made in the usual manner, and provided with the shaft 1), resting in its bearing h, and provided on its outer end with the bevel-gear l, meshing with gear 1 on the shaft 1, extending up onto the frame Gr. Within the frame G is placed the ball H, pivoted to the two arms 41 'i, the lower end of one arm being pivoted to the head 70 on the upper end of the shaft 1, and the loose end of the other arm working in a socket, 7c, in the top of the frame G, as shown in the drawing. The lower end of the shaft l is at the proper time in contact with one end of a metallic spring, which is in- 0 sulated at the point of contact with the shaft.

The other end of the spring is in metallic connection with the main-line wire, completing the circuit between the dynamo and electrophore, &c.

To enable others skilled in the art to make and use our invention, we will proceed to describe its operation.

When the dynamo is running the ball H, by reason of the centrifugal force imparted to it, 0 tends to be displaced from a central line or position within the frame Gr. This allows the shaft 1 to be drawn upward, thus relieving the pressure upon that part of the springm designed to be in contact therewith. Consequently that part of the spring nearest the connection 5 m is in metallic contact therewith, and the circuit from the dynamo is completed through the electrophore K and light. Now, when the dynamo ceases to run, the ball H, through its connections, seeks a central line or position in the frame Gr, the shaft 1 drops down and presses upon the spring m, breaks the contact at m, and the circuit is broken between the electrophore and dynamo. Consequently the electrophore completes its circuit through the light 5 alone,.and any possibility of a short circuit from the electrophore through the dynamo is prevented.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. An automatic circuit-breaker consisting of the ball H, with its arms 2' i, and the shaft 1', provided with the bevel-gear l, in combination with the shaft of the armature B of the electric generator, and spring at and electric circuit, all constructed and operated substantially as and for the purpose set forth.

2. In combination with an electrophore or secondary battery and dynamo-electric generator, with their circuits, a governor or regulator operated by the direct motion of said generator, in combination with the spring m, substantially as and for the purpose set forth.

3. In combination with a dynamo-electric 7 generator and electrophore or secondary battery, a governor or regulator consisting of the ball H, withina frame, G, and its connections with shaft Z, spring at, and contact-point m, substantially as described, and for the purpose set forth.
