Abstract
Abstract A battery driven electric clockwork mechanism is provided with a battery retaining arrangement comprising an electrical contact tongue, formed as an integral part of the mechanism, and a laminated electrical contact plate which engages an electrical contact portion of the mechanism. A notch may be formed in the tongue to ensure good contact between a positive pole of a battery and the tongue. The laminated electrical contact plate is formed at one end in a U-shaped configuration which urges against the negative pole of the battery and, thereby, forces the positive pole into pressure contact with the tongue. The clock casing may be formed with a projection for laterally supporting the tongue and an indentation may additionally be formed in the casing to support the laminated electrical contact plate therein. Pegs may be provided on the casing to removably attach the laminated electrical contact plate thereto.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
An electrical contact arrangement for a battery driven electric clockwork mechanism comprising: a. a mechanism casing; b. a battery holding arrangement within said casing and engaging the poles of a battery; c. an electrically conductive bar plate for supporting said electric clockwork mechanism; d. an electric contact tongue formed integrally with said bar plate and comprising a portion of said battery holding arrangement; e. said poles of said battery comprising a positive pole and a negative pole; f. said electrical contact tongue engaging said positive pole of said battery; g. a laminated electrical contact plate resiliently urging against said negative pole of said battery; and h. said laminated electrical contact plate being in electrical contact with said electric clockwork mechanism.
Claim 2
Dependent Claim
120 words
An electrical contact arrangement for a battery driven electric clockwork mechanism comprising: a. a mechanism casing; b. a battery holding arrangement within said casing and engaging the poles of a battery; c. an electrically conductive bar plate for supporting said electric clockwork mechanism; d. an electric contact tongue formed integrally with said bar plate and comprising a portion of said battery holding arrangement; e. said poles of said battery comprising a positive pole and a negative pole; f. said electrical contact tongue engaging said positive pole of said battery; g. a laminated electrical contact plate resiliently urging against said negative pole of said battery; and h. said laminated electrical contact plate being in electrical contact with said electric clockwork mechanism.
Claim 3
Dependent Claim
25 words
The arrangement according to claim 1, wherein said electrical contact tongue is formed with an indentation for receiving said first positive pole of said battery.
Claim 4
Dependent Claim
35 words
The arrangement according to claim 1, wherein said mechanism casing is formed with a projection for supporting said contact tongue against lateral forces applied to said contact tongue by said positive pole of said battery.
Claim 5
Dependent Claim
50 words
The arrangement according to claim 1, wherein a first end of said laminated electrical contact plate is formed in a generally U-shaped configuration having first and second legs: a. said first leg engaging said negative pole of said battery; and b. said second leg being supported by said mechanism casing.
Claim 6
Dependent Claim
31 words
The arrangement according to claim 4, wherein said second leg is formed with a pressed out eye and said mechanism casing is formed with an indentation for supportingly receiving said eye.
Claim 7
Dependent Claim
36 words
The arrangement according to claim 1, wherein said mechanism casing is formed with at least one peg and said laminated electrical contact plate is attached to said casing by means of said at least one peg.
Claim 8
Dependent Claim
20 words
The arrangement according to claim 6 wherein said at least one peg is riveted to said laminated electrical contact plate.
Claim 9
Dependent Claim
48 words
