Abstract
Abstract Easily handled, sanitary, lattice-type, metal slatted flooring is described wherein spaced slat members engage end support members through a tab-slot arrangement, the intermediate portions of the slats are affixed or spot-welded to intermediate support members and selected end tabs are affixed or spot-welded to the end support members, particularly at the corners. The method of fabrication includes the steps of cutting a series of spaced slots in the top wall of the end support members, bending the ends of precut slats to form a 90* tab at each end, spacing and aligning the support members with the slotted walls of the end members facing upwardly, placing the slats thereon with their end tabs in the spaced slots and welding the intermediate portions of the slats to the intermediate support members and only selected elbow bends of the tabs in the slotted end supports.

Claim 7
Dependent Claim
154 words
Animal pen safety flooring including a section comprising a series of equal length spaced flat-topped channel iron support members arranged in substantially parallel configuration along one axis, said channel support members having their respective ends aligned with their respective top flat walls and bottom edges arranged in substantially planar relationship, the endmost of said support members having a series of spaced slots in the top walls thereof, the longitudinal axis of said slots being coincident with said axis, a series of flat slat members arranged transversely and in spaced substantially parallel relationship across and upon the flat tops of said channel support members, said flat slat members having down-turned end tabs engaging within said slots of said endmost channel members, and rigidifying weldments at the junctures of said slat members and said intermediate channel members and at the corner junctures of said tab members of the outermost slat members and the endmost channel members.
Claim 8
Dependent Claim
