Abstract
Abstract A rectangular-faced clock is provided wherein the passage of time is indicated by the intersection of a horizontal and vertical lines moving respectively vertically and horizontally across the front of the clock. The movement of one line relative to the other and vice versa respectively represent the passage of hours and minutes. A convenient means of achieving this result is to mark the lines on endless bands trained about rollers driven by a synchronous electric motor or motors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A rectangular-faced clock wherein the passage of time is indicated by the intersection of a horizontal line moving vertically across the front of the clock and vertical line moving horizontally across the front of the clock, comprising a rectangular clock face, first and second time line means for producing at said clock face a horizontal line image and a vertical line image respectively spanning the clock face with the lines intersecting each other, and means for activating said first and second time line means to move said horizontal line vertically and said vertical line horizontally whereby the movement of one line relative to the other line represents the passage of hours and the movement of the other line relative to the one line represents the passage of minutes.
Claim 2
Dependent Claim
128 words
A rectangular-faced clock wherein the passage of time is indicated by the intersection of a horizontal line moving vertically across the front of the clock and vertical line moving horizontally across the front of the clock, comprising a rectangular clock face, first and second time line means for producing at said clock face a horizontal line image and a vertical line image respectively spanning the clock face with the lines intersecting each other, and means for activating said first and second time line means to move said horizontal line vertically and said vertical line horizontally whereby the movement of one line relative to the other line represents the passage of hours and the movement of the other line relative to the one line represents the passage of minutes.
Claim 3
Dependent Claim
84 words
A clock according to claim 1, wherein said first and second time line means comprise an endless band trained about rollers rotatable about a horizontal axis and having a horizontal line marked thereon and an endless band trained about rollers rotatable about vertical axes and having a vertical line thereon respectively forming said horizontal and vertical line images and wherein movement of the lines marked on the endless bands trained about the rollers is produced by synchronous electric motor means coupled to said rollers.
Claim 4
Dependent Claim
22 words
A clock according to claim 2, wherein graduations representing hours and minutes are also marked on the bands at the respective lines.
Claim 5
Dependent Claim
29 words
A clock according to claim 2, wherein images of graduations representing hours and minutes are provided at the front of the clock adjacent the images of the moving lines.
