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.

Abstract: A racing pigeon cage or single toss machine having an outer squirrel-cage-like shroud which is driven and rotated relative to a stationary housing having radial partitions to provide individual stalls for the pigeons. One or more of the staves or posts forming the shroud of the cage are omitted at one location so that as such location passes individual stalls, the pigeon or pigeons can exit in succession and fly to their destination, or if the shroud is made of other material such as sheet metal for example, an opening is left in the sheet metal so the birds can exit as the opening passes. The speed of rotation of the shroud may be varied to adjust the time interval of the opening of successive stalls. An electric motor or a spring motor may be used to drive the shroud with a timer to vary the period for successive opening of the stalls.
