Abstract
Apparatus for agricultural use, consisting of two dome-like, relatively-movable parts formed of plastic, the movement allowing apertures to be selectively closed or opened for admission of rain or the like.
Claims13
Plant shelter, comprising:
- (a) a dome-like lower shell having a generally vertical transparent wall with primary apertures which are sufficiently large to allow passage of bees, and
- (b) an upper shell conforming generally to the upper portion of the lower shell and having a generally vertical transparent wall which overlaps at least the upper half of the vertical wall of the lower shell and has primary apertures which are sufficiently large to allow passage of bees, the upper and lower shells being held together for relative sliding movement from a first position at which the apertures of the upper shell are coextensive with the apertures of the lower shell to allow air and bee movement in and out of the shelter to a second position at which the apertures of the upper shell are non-coextensive with the apertures of the lower shell, the upper shell being provided with a rain-collecting ridge in its upper portion in the form of a closed figure, said upper shell having secondary apertures lying within the figure, and the lower shell having similar secondary apertures for cooperation with the secondary apertures in the upper shell to drain rain water from within the ridge to the interior of the lower shell.
Plant shelter, comprising:
- (a) a dome-like lower shell having the general form of an inverted trough and having a generally vertical transparent wall with primary apertures which are sufficiently large to allow passage of bees, said lower shell having generally straight-line lower edges in spaced, parallel relationship, each of said lower edges being formed with inclined portions that permit locking with the earth, said lower shell having secondary apertures in its upper surface, and
- (b) an upper shell having a general form of an inverted trough and conforming generally to a portion of the lower shell and having a generally vertical transparent wall with primary apertures which are sufficiently large to allow passage of bees, the upper and lower shells being held together for relative straight line, generally horizontal sliding movement from a first position at which the primary apertures of the upper shell are coextensive with the primary apertures of the lower shell to allow air and bee movement in and out of the shelter to a second position at which the primary apertures of the upper shell are non-coextensive with the primary apertures of the lower shell, the upper shell being provided with a rain-collecting ridge in its upper portion in the form of a closed FIG., said upper shell having secondary apertures lying with the FIG. for cooperation with the secondary apertures in the lower shell to drain rain water from within the ridge to the interior of the lower shell.
Plant shelter, comprising:
- (a) a dome-like lower shell having a generally vertical transparent wall with primary apertures which are sufficiently large to allow passage of bees, the upper surface of said lower shell being provided with upwardly extending bosses which are formed with secondary apertures, and
- (b) an upper shell conforming generally to a portion of the lower shell and having a generally vertical transparent wall with relatively large apertures which are sufficiently large to allow passage of bees, the upper shell being supported on said bosses for relative sliding movement from a first position at which the primary apertures of the upper shell are coextensive with the primary apertures of the lower shell to allow air and bee movement in and out of the shelter to a second position at which the primary apertures of the upper shell are non-coextensive with the primary openings of the lower shell, the upper shell being provided with a rain-collecting ridge in its upper portion in the form of a closed figure, said upper shell having secondary apertures lying with the figure, and adapted to be aligned with the secondary apertures of the lower shell apertures for cooperation with the secondary apertures in the lower shell to drain rain water from within the ridge to the interior of the lower shell.
