Abstract
564,011. Poultry houses &c. SMITH, S. May 21, 1943, No. 8076. [Class 5 (ii)) A trap-nest is provided with a hinged flap released to close the entrance by contact with the flap. A hinge-pin D on the upper edge of the flap B is engaged in vertical slots E in brackets F mounted on the top bar C. Projections H which may be struck up from the material of the flap rest against the backs of the brackets and maintain the pin D at the upper position. Engagement of a fowl's back with the lower edge of the flap tilts the latter, causes the pin D to fall and the projections H to clear the brackets. The flap falls and may be kept closed by a spring catch K. Ventilation openings may be formed in the flap.
