ABSTRACT:
A fully automatic pigeon basket, crate, or cage assembly comprising vertically stacked stalls arranged in several vertical rows, having several vertically slidable doors covering all of said stalls (one sliding door per vertical column of stalls) and opened by gravity. Each portion of the sliding front door covering a stall is provided with an internally extending stop which is firmly attached to the inner side of the door. An electromagnetic solenoid positioned at the bottom of each vertical column of stalls, having an armature or piston against which the stop rests when the solenoid is deenergized, controls the drop of the door. Upon a fraction of a second energization of each individual solenoid, the armature is withdrawn from its supporting position of the stop, then immediately pushed back out to the extended stop position by a spring, thereby allowing just one stop to drop down with the sliding door by gravity to the next higher stop positioned on the door at which time the downward movement of the stop is arrested, allowing full opening of the upper door portion of the upper stall.
A fully automatic electrical system controls the various solenoids to provide a timed interval between the opening of one stall and a lower stall so that the pigeons are released, one at a time, at timed intervals. In some cases, two or more stalls may be opened at the same time after a timed interval.
