Abstract
Abstract A half-silvered mirror closes off one end of a peripheral housing, in spaced relation behind which half-silvered mirror is a clock face. Lighting means within the space between the half-silvered mirror and the clock face provides for selective illumination of the clock face for visualization through the half-silvered mirror. Sound actuated means is also provided for selective temporary energization of the lighting means to illuminate the clock face for time telling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A sound actuated clock-mirror comprising, in combination, peripheral housing having front and back ends, a partially silvered flat mirror secured to and enclosing the front end of said housing, a flat clockwork support panel fixed within said peripheral housing in spaced relation with respect to said half-silvered mirror, a clockwork supported by said support panel and having its hands located within the space between said clockwork panel and said half-silvered mirror for reading against the inner surface of said support panel and for selective observation through said mirror, electrical lighting means within the space between said half-silvered mirror and said clockwork support panel, and an energization circuit for said electrical lighting means, said energization circuit comprising a sound-actuated electronic switch for selectivly energizing said lighting means upon the creation of a pre-determined sound.
Claim 2
Dependent Claim
133 words
A sound actuated clock-mirror comprising, in combination, peripheral housing having front and back ends, a partially silvered flat mirror secured to and enclosing the front end of said housing, a flat clockwork support panel fixed within said peripheral housing in spaced relation with respect to said half-silvered mirror, a clockwork supported by said support panel and having its hands located within the space between said clockwork panel and said half-silvered mirror for reading against the inner surface of said support panel and for selective observation through said mirror, electrical lighting means within the space between said half-silvered mirror and said clockwork support panel, and an energization circuit for said electrical lighting means, said energization circuit comprising a sound-actuated electronic switch for selectivly energizing said lighting means upon the creation of a pre-determined sound.
Claim 3
Dependent Claim
54 words
A sound actuated clock-mirror as defined in claim 1 wherein the inside of said clockwork support panel comprises a clock face, and wherein said electrical lighting means comprises a plurality of electrical lamps peripherally arranged with respect to said clock face and in spaced relation with respect to the inner periphery of said housing.
Claim 4
Dependent Claim
75 words
A sound actuated clock-mirror as defined in claim 2 including support means for said plurality of electrical lamps, said lamps support means comprising opaque divider strip means extending between the insides of said half-silvered mirror and said clockwork support panel, said divider strip means being operative to prevent light from said electrical lamps radiating into the peripheral marginal zone between the inner periphery of said housing and the outer periphery of said divider strip means.
Claim 5
Dependent Claim
43 words
A sound actuated clock-mirror as defined in claim 3 and further including an opaque mask fitted against the inside of said half-silvered mirror at the peripheral zone between the inside of said peripheral housing and the peripheral outside of said divider strip means.
Claim 6
Dependent Claim
17 words
A sound actuated clock-mirror as defined in claim 2 wherein said peripheral housing is rectangular in shape.
Claim 7
Dependent Claim
35 words
A sound actuated clock-mirror as defined in claim 5 wherein said electrical lamps are arranged in spaced relation along lines defining a rectangle within the rectangle defined by the inner walls of said rectangular housing.
Claim 8
Dependent Claim
73 words
A sound actuated clock-mirror as defined in claim 6 including support means for said plurality of electrical lamps, said lamp support means comprising four opaque divider strips extending between the insides of said half-silvered mirror and said clockwork support panel, said divider strips being operative to prevent light from said electrical lamps radiating into the peripheral marginal zone between the inner periphery of said housing and the outer periphery of said divider strips.
Claim 9
Dependent Claim
39 words
A sound actuated clock-mirror as defined in claim 7 and further including an opaque mask fitted against said half-silvered mirror at the peripheral zone between the inside of said peripheral housing and the peripheral outside of said divider strips.
Claim 10
Dependent Claim
21 words
A sound actuated clock-mirror as defined in claim 8 including a closure panel fitted against the back end of said housing.
Claim 11
Dependent Claim
27 words
A sound actuated clock-mirror as defined in claim 2 wherein said electrical circuit comprises means for de-energizing the electronic switch at a pre-determined interval after its energization.
