    摘要: A barrier device for installation in a drain tile adjacent the outlet of the tile includes a plurality of spaced apart barrier elements affixed to a sleeve to define a perforate gate. The gate is swingably mounted on a pivot rod which projects transversely through openings in the tile adjacent the outlet of the latter. The barrier elements, which are in the form of rods, are affixed to the sleeve to normally urge the gate to a closed position by action of gravity to thereby prevent entry by small animals into the tile. The gate may swing to the open position when engaged by floating debris to thereby permit passage of the debris through the drain tile outlet.

    摘要: The chair has a support structure with a wide stable base. The chair has a single inverted U-shaped tubular metal main frame. Near the top and inside of the frame is connected a tubular metal back leg unit set of two legs to swing out away from the inverted U-shaped frame. The support structure is also characterized by possessing:a. A pair of horizontal metal cross-bars affixed within the tubular metal main frame, one near the top and the other near the bottom; andb. A pair of metal tubes attached to and between the cross-bars and situated substantially in the same plane as the main frame.The back leg unit is pivotally connected to the main frame near the top thereof, the legs of the back unit being angled away from vertical near the top of the unit, and said back unit also possessing a pair of metal horizontal crossbars, one of said bars being located slightly below the angular bends in the legs of the back unit and the other bar being located near the bottom of the back unit, and the base of the legs of the back unit being bent substantially at right angles outwardly from the legs.
