Abstract

1514738 Irrigation channels; feeding troughs H D SHARMAN 30 Jan 1976 [12 Dec 1974] 53726/74 Headings A1B and AIM [Also in Division B5] Irrigation troughing or feed and/or drinking troughing for animals and poultry is made from sheeting 10 having opposed marginal edges 12 each strengthened by permanently deforming the edge into ridges 16, 18, projecting alternately from opposite sides of the sheeting, and locating on each edge 12 a rigid reinforcing tube 26, 28 with the sheeting extending through an axial slot 27 therein. Legs of a U-shape staple 38 pass through holes 32, 34 in the tubes 26, 28 to hold the troughing in position.
