Abstract
Abstract An arrangement for measuring the voltage of a battery to determine the state of charge of the battery when used to operate electrical clocks. A momentary contact switch actuated by the clock mechanism at regular time intervals, connects the battery to a voltage-measuring instrument. An indicating device associated with the instrument is held in place by a holding device, after the measurement has been taken. The indicating device becomes released and permitted to return to its initial position prior to the instant when a subsequent measurement is to be taken. The clock mechanism in the form of the hour wheel actuates the momentary constant switch.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A measuring and indicating arrangement comprising, in combination, a source of electrical energy of which a parameter is to be measured; measuring means connectable to said source of electrical energy for measuring said parameter; momentary contact means for connecting momentarily said source of electrical energy to said measuring means at predetermined time intervals; clock means operated by said source of electrical energy and actuating said momentary contact means; indicating means associated with said measuring means for indicating the measurement taken by said measuring means; and holding means for holding said indicating means at said measurement taken after disconnecting said source of electrical energy from said measuring means by said momentary contact means.
Claim 2
Dependent Claim
112 words
A measuring and indicating arrangement comprising, in combination, a source of electrical energy of which a parameter is to be measured; measuring means connectable to said source of electrical energy for measuring said parameter; momentary contact means for connecting momentarily said source of electrical energy to said measuring means at predetermined time intervals; clock means operated by said source of electrical energy and actuating said momentary contact means; indicating means associated with said measuring means for indicating the measurement taken by said measuring means; and holding means for holding said indicating means at said measurement taken after disconnecting said source of electrical energy from said measuring means by said momentary contact means.
Claim 3
Dependent Claim
22 words
The measuring and indicating arrangement as defined in claim 1 wherein said parameter is the voltage of said source of electrical energy.
Claim 4
Dependent Claim
29 words
The measuring and indicating arrangement as defined in claim 1 wherein said momentary contact means comprises a wiping contact switch actuated by the hour wheel of said clock means.
Claim 5
Dependent Claim
50 words
The measuring and indicating arrangement as defined in claim 1 wherein said holding means comprises a slide member mechanically coupled to said momentary contact means, said slide member holding said indicating means at said measurement taken and thereafter releasing said indicating means prior to the taking of a subsequent measurement.
Claim 6
Dependent Claim
35 words
The measuring and indicating arrangement as defined in claim 4 said slide member being released by the hour wheel of said clock means and thereby releasing said indicating means to return to its initial position.
Claim 7
Dependent Claim
39 words
The measuring and indicating arrangement as defined in claim 1, including means actuating said holding means for releasing said indicating means after a predetermined interval, said indicating means returning to its initial position after release from said holding means.
