Abstract
Abstract An insolation survey device for determining the exposure of a reference point to a cyclically varying radiation source. The device employs a base member for horizontally supporting a display sheet premarked with a grid calibrated in units corresponding to the measurement being taken. A transparent reflective member is supported by the base member over the display sheet so that a reflected view of the surrounding appurtenances and the view of the display sheet, through the transparent dome, form one composite picture. In the composite picture so formed, the period or periods, if any, within the radiation cycle that the reference point will be exposed to said radiation appear as unobstructed sky superimposed onto the premarked grid. A compass is provided to directionally align the device and means are provided for orienting the base member in a true horizontal plane.

Claim 1
Independent Claim
77 words
An insolation survey device for forming visual representation of the quantity of direct, time-varying exposure of a pre-selected location to solar radiation comprising means reflecting said radiation for forming a visible, reflected pattern corresponding to said areas of direct radiation, calibrated display sheet means for forming a composite visual image of said calibrations with said visual reflected patterns; direction indicating means for said display sheet and means for leveling said display sheet with respect to the horizontal.
Claim 2
Dependent Claim
77 words
An insolation survey device for forming visual representation of the quantity of direct, time-varying exposure of a pre-selected location to solar radiation comprising means reflecting said radiation for forming a visible, reflected pattern corresponding to said areas of direct radiation, calibrated display sheet means for forming a composite visual image of said calibrations with said visual reflected patterns; direction indicating means for said display sheet and means for leveling said display sheet with respect to the horizontal.
Claim 3
Dependent Claim
25 words
The insolation survey device of claim 1 further including a horizontally alignable planar surface for supporting said calibrated display sheet means beneath said reflecting means.
Claim 4
Dependent Claim
25 words
The insolation survey device of claim 2 wherein said reflecting means comprises a thin, transparent dome supported by planar surface above said calibrated display sheet.
Claim 5
Dependent Claim
21 words
The insolation survey device of claim 3 wherein said planar surface further includes means for directionally aligning said insolation survey device.
Claim 6
Dependent Claim
16 words
The insolation survey device of claim 4 wherein said directional alignment means comprises a magnetic compass.
Claim 7
Dependent Claim
19 words
The insolation survey device of claim 2 further including means for aligning said planar surface in a horizontal plane.
Claim 8
Dependent Claim
38 words
The insolation survey device of claim 6 wherein said aligning means comprises a bubble level and an alignment ring whereby said planar surface is horizontally aligned when said bubble in said level is centered in said alignment ring.
Claim 9
Dependent Claim
39 words
The insolation survey device of claim 7 wherein said transparent dome further includes a tracing aperture adapted to provide access to the interior of said dome for tracing said image of direct areas of radiation on said display sheet.
Claim 10
Dependent Claim
137 words
An insolation survey device for forming a visible representation of the quantity of direct exposure of a preselected location to light radiation from a radiation source, said visible representation comprising shadow areas representing appurtenant obstructions to said direct exposure and lighter areas representing said direct exposure, said insolation survey device comprising: a planar surface; means above said planar surface for receiving light radiations and reflecting said light in such manner as to form a visual representation of surrounding appurtenances; a calibrated display sheet means supported on said planar surface on which the reflected images of surrounding appurtenances are visible to the end that said visual representation of surrounding appurtenances appear to be superimposed on said calibrated sheet means; means for directionally aligning said display sheet and means for aligning said display sheet with respect to the horizontal.
Claim 11
Dependent Claim
137 words
An insolation survey device for forming a visible representation of the quantity of direct exposure of a preselected location to light radiation from a radiation source, said visible representation comprising shadow areas representing appurtenant obstructions to said direct exposure and lighter areas representing said direct exposure, said insolation survey device comprising: a planar surface; means above said planar surface for receiving light radiations and reflecting said light in such manner as to form a visual representation of surrounding appurtenances; a calibrated display sheet means supported on said planar surface on which the reflected images of surrounding appurtenances are visible to the end that said visual representation of surrounding appurtenances appear to be superimposed on said calibrated sheet means; means for directionally aligning said display sheet and means for aligning said display sheet with respect to the horizontal.
Claim 12
Dependent Claim
52 words
The insolation survey device of claim 9 wherein said display sheet means is calibrated in increments of solar time and calendar dates whereby the periods of direct radiation exposure of said pre-selected location for a predetermined date may be computed by adding the time intervals representing direct exposure on said predetermined date.
Claim 13
Dependent Claim
84 words
The insolation survey device of claim 9 wherein said display sheet means is calibrated with (1) concentric circles appropriately spaced from the center of a display sheet and (2) uniformly spaced radial lines extending from the center of said display sheet. The horizontal and vertical angle between a said appurtenance viewed from said pre-selected location and reference point can be determined from the intersection of said image representing said appurtenance and a said radial line and a said concentric circle on said display sheet.
Claim 14
Dependent Claim
101 words
An insolation survey device for forming a visual pattern of the amounts of direct time varying exposure of a pre-selected location to solar radiation comprising: a planar support; means above said planar surface for receiving solar radiations and reflecting said radiations in such manner as to form a visual representation of surrounding appurtenances thereon; means for aligning said support plate in a horizontal plane; means for directionally aligning said support plate; and a calibrated display sheet means supported on said planar support plate on which the reflected pattern of surrounding appurtenances reflected on said radiation receiving means appear to be superimposed.
Claim 15
Dependent Claim
101 words
An insolation survey device for forming a visual pattern of the amounts of direct time varying exposure of a pre-selected location to solar radiation comprising: a planar support; means above said planar surface for receiving solar radiations and reflecting said radiations in such manner as to form a visual representation of surrounding appurtenances thereon; means for aligning said support plate in a horizontal plane; means for directionally aligning said support plate; and a calibrated display sheet means supported on said planar support plate on which the reflected pattern of surrounding appurtenances reflected on said radiation receiving means appear to be superimposed.
