Claim 1
Independent Claim
194 words
Appratus for converting terrestrial nominal time and position to siderial time and position with respect to the plane of the ecliptic and comprising a base sheet, indicia dividing the base sheet along radial lines, including a solstice line, said radial lines being a projection to the base sheet of a like radially divided circle tilted at an angle to the base sheet equal to the tilt of the equatorial plane of the earth to the ecliptic plane of the planets; a light transmitting second sheet pivotally and slidably secured to the base sheet to move thereupon parallel to the solstice line, indicia on the second sheet including lines parallel to a central axis of the second sheet passing through the pivot point of the second sheet with respect to the base sheet; and a time chart secured to move with the second sheet and adapted to pivot with respect to the base sheet and the second sheet, and indicia on the time chart dividing said chart in accordance with the hours of a terrestrial day; and base sheet indicia indicating the displacement along the solstice line in accordance with latitude from the terrestrial equator.

Dependent Claim
65 words
Apparatus in accordance with claim 1 further comprising parallel base sheet walls defining a slot passing through the center of the base sheet at the focus of the radial lines and extending along the solstice line of the base sheet, a slider adapted to move in the slot defined by the walls, and means securing the second sheet and the time chart to the slider.
Claim 4
Dependent Claim
35 words
Apparatus in accordance with claim 1 wherein the base sheet indicia are discernable through the second sheet such that coincidence or noncoincidence of seCond sheet parallel lines with underlying base sheet radial lines is observable.
