Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
141 words
A revolving greenhouse comprising: a hollow outer cylinder revolvably mounted on a support means to have the longitudinal axis thereof horizontally oriented, said cylinder having a lateral surface; translucent means forming a first portion of said cylinder lateral surface and opaque means forming the remainder of said cylinder lateral surface; bench means in said cylinder extending longitudinally thereof, for supporting plants or the like in said cylinder; roller means supporting said bench means on said cylinder; a walkway extending longitudinally of said cylinder near said bench means; cylinder revolving means for revolving said cylinder about said longitudinal axis for exposing said translucent and said opaque means to sunlight, said revolving means including idler rollers contacting said cylinder lateral surface, drive rollers contacting said cylinder lateral surface and drive means connected to said drive rollers for driving same to revolve said cylinder.
Claim 2
Dependent Claim
141 words
