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 timepieces. A pair of momentary contact switches are actuated by the hours wheel of the clock mechanism on the one hand, and by either the minutes wheel or the seconds wheel of the clock mechanism on the other hand, and when actuated in coincidence complete an electrical circuit which connects the battery with a voltage measuring instrument. An indicating device associated with the instrument indicates the measurement taken and is held in place by a holding device, after the measurement has been completed. The indicating device becomes released and permitted to turn to its initial position prior to the instant when a subsequent measurement is to be taken.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 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 for measuring said parameter; clock means operated by said source and including a clockwork; a first and a second switch actuated by said clockwork at predetermined time intervals in coincidence and completing, when so actuated, an electric circuit connecting said source and said measuring means; and indicating means associated with said measuring means for indicating the measurement taken by the latter.
Claim 2
Dependent Claim
88 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 for measuring said parameter; clock means operated by said source and including a clockwork; a first and a second switch actuated by said clockwork at predetermined time intervals in coincidence and completing, when so actuated, an electric circuit connecting said source and said measuring means; and indicating means associated with said measuring means for indicating the measurement taken by the latter.
Claim 3
Dependent Claim
47 words
An arrangement as defined in claim 1, wherein said clockwork comprises an hours wheel, a minutes wheel, and a seconds wheel; and wherein one of said switches is actuated by said hours wheel and the other of said switches is actuated by one of the remaining wheels.
Claim 4
Dependent Claim
36 words
An arrangement as defined in claim 2; and further comprising holding means for holding said indicating means at the position indicating the measurement taken, after disconnecting of said source from said measuring means by said switches.
Claim 5
Dependent Claim
16 words
An arrangement as defined in claim 2, wherein said one remaining wheel is said seconds wheel.
Claim 6
Dependent Claim
16 words
An arrangement as defined in claim 2, wherein said one remaining wheel is said minutes wheel.
Claim 7
Dependent Claim
15 words
An arrangement as defined in claim 1, wherein said indicating means is a lag indicator.
Claim 8
Dependent Claim
29 words
An arrangement as defined in claim 3; and further comprising release means on said hours wheel operative for releasing said holding means for return thereof to its initial position.
Claim 9
Dependent Claim
32 words
An arrangement as defined in claim 7, said release means comprising a cam provided on said hours wheel and arranged to engage and act upon said holding means for releasing the same.
Claim 10
Dependent Claim
19 words
An arrangement as defined in claim 1, wherein said parameter is the voltage of said source of electrical energy.
Claim 11
Dependent Claim
54 words
An arrangement as defined in claim 2, wherein each of said switches comprises two spaced contacts, and wherein each of said hours wheel and said one remaining wheel is provided with an electrically conductive portion positioned for temporary bridging of said contacts of the associated switch in response to rotation of the respective wheel.
