Abstract

Abstract An improved weather test apparatus is disclosed. The basic structure includes a reflecting mirror support frame, reflecting mirrors mounted thereon for condensing sunlight towards a test piece, and a support member for positioning the test piece for receiving the condensed sunlight. The improvement specifically relates to a rotary test piece support member for use in conjunction with the basic structure. This member includes a pair of multi-sided end plates separated by a plurality of transverse members, one transverse member extending between each corresponding corner of the multi-sided end plates. A plurality of test piece adaptor plates are connected between the end plates, one adaptor plate being positioned parallel to each side of the multi-sided end plates. The adaptor plates, however, are separated from each other and air flow passages are thereby defined between adjacent adaptor plates. A plurality of air flow adjusting plates, one slidably mounted on each transverse member, is provided for adjusting the air flow through the rotary test piece support member. The rotary member is connected to the support member by a first shaft which is fixedly coupled to one of the end plates for rotating the test base support member and a second shaft, one end thereof being slidably coupled to and extending through the other of the end plates. The first shaft extends through the support member and is rotated by an appropriate drive chain while the second shaft is rigidly coupled to the support member. The second shaft is hollow, and the portion which extends into the rotary member is open. An air pump is coupled to the second shaft for circulating air therethrough into the rotary test piece support member and an arcuate wind direction plate is positioned within the test piece support member over the second shaft and downwardly extending thereabout.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 262 words
An improved weather test apparatus including a reflecting mirror support frame, reflecting mirrors mounted thereon for condensing sunlight toward a test piece, and a support member for positioning the test piece for receiving the condensed sunlight thereupon, wherein the improvement comprises: a rotary test piece support member comprised of a pair of multisided end plates, a plurality of transverse members, each connecting a respective corner of said end plates for rigid separation thereof, a plurality of test piece adaptor plates connected between said end plates at locations corresponding to each of the sides of said end plates and having test pieces supported thereon, said test piece adaptor plates defining air flow passages between adjacent adaptor plates, a plurality of air flow adjusting plates, at least one mounted on each of said transverse members for slidable movement laterally of said transverse member, a first shaft fixedly coupled to one of said end plates, said first shaft adapted for rotating said test piece support member, a second shaft, one end thereof being slidably coupled to and extending through the other of said end plates into the interior of the said rotary test piece support member and the other end being rigidly mounted to said support member, said second shaft being hollow and said one end being open within the interior of said test piece support member, and an arcuate wind direction plate positioned over said second shaft and downwardly extending thereabout; means for rotating said first shaft, operatively coupled thereto and to said support member, and air blowing means coupled to said second shaft.
Claim 2
Dependent Claim 262 words
An improved weather test apparatus including a reflecting mirror support frame, reflecting mirrors mounted thereon for condensing sunlight toward a test piece, and a support member for positioning the test piece for receiving the condensed sunlight thereupon, wherein the improvement comprises: a rotary test piece support member comprised of a pair of multisided end plates, a plurality of transverse members, each connecting a respective corner of said end plates for rigid separation thereof, a plurality of test piece adaptor plates connected between said end plates at locations corresponding to each of the sides of said end plates and having test pieces supported thereon, said test piece adaptor plates defining air flow passages between adjacent adaptor plates, a plurality of air flow adjusting plates, at least one mounted on each of said transverse members for slidable movement laterally of said transverse member, a first shaft fixedly coupled to one of said end plates, said first shaft adapted for rotating said test piece support member, a second shaft, one end thereof being slidably coupled to and extending through the other of said end plates into the interior of the said rotary test piece support member and the other end being rigidly mounted to said support member, said second shaft being hollow and said one end being open within the interior of said test piece support member, and an arcuate wind direction plate positioned over said second shaft and downwardly extending thereabout; means for rotating said first shaft, operatively coupled thereto and to said support member, and air blowing means coupled to said second shaft.
Claim 3
Dependent Claim 22 words
The device of claim 1 wherein said means for rotating said first shaft operates continuously and intermittently according to the affects desired.
Claim 4
Dependent Claim 38 words
The device of claim 2 wherein said end plates are square, four transverse members are provided, each having a square cross-section and a bearing positioned centrally of one of said end Plates through which said second shaft extends.
Claim 5
Dependent Claim 59 words
The device of claim 3 wherein said means for rotating said first shaft is positioned on said support member opposite the location of said rotary test piece support member, said frame member having an aperture therein, a bearing positioned in said aperture and said first shaft extending therethrough and being coupled to said means for rotating said first shaft.
