Abstract
Abstract A clock has a clock face in the form of an axially symmetric solid, e.g. a sphere, a cone or a cylinder. Clock hands extend around the clock face following a helical path, and time-indicating markings are arranged on all the surfaces of the face. It is therefore possible for a complete set of these markings to be seen from any direction relative to the clock face. The hands are normally driven by a conventional clock movement, there being an hour hand and a minute hand. However, it would be possible in some applications to have only a single hand, e.g. a minute hand, and to drive the clock face relative to the hand. The markings are arranged along helical paths, corresponding to the helical shape of the hands.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A clock comprising a clock face with an annular clock face surface which extends radially outwardly and axially from each end thereof toward the other end and which is thereby viewable from any radial direction and both axial directions thereof, hour and minute hands mounted coaxially with the annular clock face surface for relative rotation with respect thereto, the clock face having a plurality of at least four regularly spaced sets of time indicia each comprising a plurality of time indicia angularly spaced about the clock surface, each of said hands extending in generally spaced parallel relationship with the clock face surface between the ends thereof and extending angularly at least 360° for indicating the hour and minutes with the clock face indicia from any radial direction and both axial directions of the clock face surface, and a clock mechanism for rotating the hour and minute hands relative to the clock face.
Claim 2
Dependent Claim
152 words
A clock comprising a clock face with an annular clock face surface which extends radially outwardly and axially from each end thereof toward the other end and which is thereby viewable from any radial direction and both axial directions thereof, hour and minute hands mounted coaxially with the annular clock face surface for relative rotation with respect thereto, the clock face having a plurality of at least four regularly spaced sets of time indicia each comprising a plurality of time indicia angularly spaced about the clock surface, each of said hands extending in generally spaced parallel relationship with the clock face surface between the ends thereof and extending angularly at least 360° for indicating the hour and minutes with the clock face indicia from any radial direction and both axial directions of the clock face surface, and a clock mechanism for rotating the hour and minute hands relative to the clock face.
Claim 3
Dependent Claim
22 words
A clock according to claim 1 wherein the hands are mounted to rotate outside of and close to the clock face surface.
Claim 4
Dependent Claim
29 words
A clock according to claim 1 wherein the clock face surface is divided into a plurality of angularly spaced different colored regions extending axially and angularly about the surface.
Claim 5
Dependent Claim
24 words
A clock according to claim 1 wherein each set of time indicia comprises a circular arrangement of numerals coaxial with the clock face surface.
Claim 6
Dependent Claim
15 words
A clock according to claim 1 wherein the clock face has a generally sphere-shaped surface.
Claim 7
Dependent Claim
79 words
A clock according to claim 1 wherein the clock face surface comprises an axially facing generally flat annular portion at least at one axial end of the clock face, wherein the sets of indicia include a set of indicia angularly spaced about said axially facing annular portion, and wherein the hour and minute hands each extend generally radially along said annular portion for reading the hour and minutes respectively from said one axial end of the clock face. .Iadd.
Claim 8
Dependent Claim
199 words
A clock comprising a clock face with an annular clock face surface of revolution which extends radially outwardly and axially from each end thereof toward the other end and which is thereby viewable from any radial direction and both axial directions thereof, hour and minute hands mounted coaxially with the annular clock face surface for relative rotation with respect thereto, the clock face having a plurality of at least four regularly spaced sets of time indicia each comprising a plurality of time indicia angularly spaced about the clock surface, each of said hands cooperating with the clock face surface between the ends thereof and extending angularly sufficiently for indicating the hour and minutes with the clock face indicia from any radial direction and both axial directions of the clock face surface, and a clock mechanism for rotating the hour and minute hands relative to the clock face. .Iaddend. .Iadd.8. A clock according to claim 7 wherein the hands are mounted to rotate outside of and close to the clock face surface. .Iaddend. .Iadd.9. A clock according to claim 7 wherein the clock face surface is divided into a plurality of angularly spaced different colored regions extending axially and angularly
Claim 9
Dependent Claim
127 words
about the surface. .Iaddend. .Iadd.10. A clock according to claim 7 wherein each set of time indicia comprises a circular arrangement of numerals coaxial with the clock face surface. .Iaddend. .Iadd.11. A clock according to claim 7 wherein the clock face has a generally sphere-shaped surface. .Iaddend. .Iadd.12. A clock according to claim 7 wherein the clock face surface comprises an axially facing generally flat annular portion at least at one axial end of the clock face, wherein the sets of indicia include a set of indicia angularly spaced about said axially facing annular portion, and wherein the hour and minute hands each extend generally radially along said annular portion for reading the hour and minutes respectively from said one axial end of the clock face. .Iaddend.
