Abstract

A truss for supporting cages in a poultry cage system comprises a pair of inclined upstanding legs and a series of vertically-spaced horizontal cross-members connected thereto by novel clips which are specially designed to enable the cross-members to be connected to the legs with a minimum of labor. Opposite ends of each cross-member have a pair of spaced apertures which register with a pair of similarly-spaced apertures in the truss legs. The clip has a front flange with a pair of rearwardly turned lugs which are received in the leg and arm apertures and which have hooks located below the lower edges of the apertures. The legs also have holes located below their apertures and below the lower edge of the cross-member, and the clip has a deformable angulated tab depending from the lower portion of the flange and extending into the holes in the legs. To assemble the truss, the clip is engaged with the cross-member and is inserted into the leg apertures, after which the cross-member and clip are slid downwardly to cause the tab to register with the hole in the leg, whereupon the tab is struck by a hammer and engaged in the hole for locking the cross-member to the leg.
