Camera for recording solar access to a site
First Claim
1. A camera for photographing a geographical site and superimposing indicia on the film exposure to evaluate solar access to the site, said camera comprising,a body defining an internal area, a shutter assembly thereon including light admitting means for film exposure,an indicia bearing member within the internal area and having both light translucent and opaque areas, said indicia bearing member in the path of shutter admitted light, said opaque areas constituting indica representing an apparent path of the sun above a horizon viewed through the camera, andfilm guide means within said body adapted to guide the film past said indicia bearing member whereby shutter assembly actuation results in an image of the photographed object being imparted to the so positioned film when exposed along with the imparting of an image of the indicia to the film.

Abstract
A camera is disclosed as being of the pin hole type having a transparent member therewithin on which is printed sun paths for certain days of the year and local time sun positions for the purpose of superimposing same on the photograph taken. Obstructions to direct solar radiation may then be calculated from an examination of the resulting photograph to determine the suitability of a site for future use of solar energy. A compass and level on the camera body facilitate southerly orientation of the camera in a level position. Film rollers guide the film over the curved indicia bearing member. Film transfer means retains a film supply roll with a take-up spindle for exposed film. A shutter assembly permits light entry through a pin hole aperture with the camera having a short focal length for a wide angle field. The indicia bearing member is detachably mounted to enable substitution of appropriate like members for use at different latitudes.
