Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
In a timepiece equipped with a mechanical unit including sound producing means for producing a time-ticking sound, such as an escapement having isochronism, the improvement comprising, an outer casing; a sound proof inner casing within said outer casing, said inner casing containing said mechanical unit; buffer means supporting said inner casing in spaced relation to said outer casing, said buffer means accoustically isolating said inner casing from said outer casing; sound level adjusting means for conveying sound produced by the mechanical unit from said inner casing, said sound level adjusting means including means for freely adjusting the level of the sound conveyed from said inner casing in a range from a condition of essentially silence to a predetermined level; and means for enlarging the sound conveyed from the inner casing.
Claim 2
Dependent Claim
130 words
In a timepiece equipped with a mechanical unit including sound producing means for producing a time-ticking sound, such as an escapement having isochronism, the improvement comprising, an outer casing; a sound proof inner casing within said outer casing, said inner casing containing said mechanical unit; buffer means supporting said inner casing in spaced relation to said outer casing, said buffer means accoustically isolating said inner casing from said outer casing; sound level adjusting means for conveying sound produced by the mechanical unit from said inner casing, said sound level adjusting means including means for freely adjusting the level of the sound conveyed from said inner casing in a range from a condition of essentially silence to a predetermined level; and means for enlarging the sound conveyed from the inner casing.
Claim 3
Dependent Claim
25 words
A timepiece according to claim 1 wherein, said sound level adjusting means comprises means for manually adjusting the level of conveyed sound at any time.
Claim 4
Dependent Claim
61 words
A timepiece according to claim 1 wherein said second level adjusting means comprises conduction means engageably with said mechanical unit for mechanically conducting vibrations from said inner casing to said outer casing, and means for manually controlling the pressure of engagement of the conduction means with the mechanical unit to control the level of the sound conducted to the outer casing.
Claim 5
Dependent Claim
40 words
A timepiece according to claim 3 wherein said conduction means comprises an axially moveable sound conducting element, and means mounting said element for axially movement to vary the pressure thereof against said mechanism in response to rotation of said element.
Claim 6
Dependent Claim
50 words
A timepiece according to claim 3 wherein said conduction means comprises a rotatable element, a cam on said element and within said inner casing; a spring on said mechanical unit, and means outside said outer casing for rotating said element to change the pressure of the cam on said spring.
Claim 7
Dependent Claim
29 words
A timepiece according to claim 3 wherein said means for enlarging the sound comprises an outer casing resonant at the frequency of the sound conducted from the inner casing.
Claim 8
Dependent Claim
57 words
A timepiece according to claim 1 wherein said sound conveying means comprises an opening in said inner casing between said mechanical unit and said outer casing, and closure means for said opening, and said level adjusting means comprises means on the outside of the outer casing for moving said closure between an open and a closed position.
Claim 9
Dependent Claim
34 words
A timepiece according to claim 7 further comprising means on said outer casing for engaging said closure to further transmit sound by conduction through said closure between said inner casing and said outer casing.
Claim 10
Dependent Claim
20 words
A timepiece according to claim 1 wherein said means for enlarging the sound comprises a megaphone on said outer casing.
