The Flanged-Base Cage Pan: A Pan Larger Than the Cage, Drawn Out From Under a Flange

"The base 4 is of substantially usual form, and near its outer edge I attach an upright rim 5, which extends on two sides and across one end. At the upper edge this rim is turned inward, forming a flange 6." "As the edge of the drawer extends beneath the flange 6 and as the cage sets within the flange, it follows that the drawer is of greater dimensions than the dimensions of the cage, so that all refuse falling within the cage must necessarily fall within the pan, and this pan and its contents may be readily withdrawn without disengaging the body of the cage from the base."

**Base.** Measure the bought cage's bottom rim. Saw a hardwood board 6 cm longer and wider than it. **Rim and flange.** Cut a strip of aluminium sheet 4.5 cm wide and long enough for two sides and one end. Fold 1.5 cm of one edge out flat as a foot, 2 cm up as the rim, and the last 1 cm inward as the flange. Screw the feet to the board 1.5 cm in from its edge along those three sides, so the flange's inner edge stands 5 mm outside the cage's rim all round. **Pan.** Fold a tray from aluminium sheet that slides in over the board under the flange and fills the rim, with sides 1.5 cm high, so it is 1.5 cm larger than the cage all round. At its open end fold a front as tall as the rim, turned in at the top like the flange, and screw a small dowel knob to it. **Cage.** Drill four holes in the flange and pass a hook bent from galvanised wire down through each, so the cage's bottom rim rests on the hooks just below the flange's top, clear of the pan. Twist a wire clip over the rim at each hook to lock the cage to the base. **Test.** Scatter a counted cupful of lentils over the cage floor and count those in the pan and outside it; repeat with a tray cut 2 cm smaller than the cage all round.

**Andrew B. Hendryx** of New Haven, Connecticut, filed US 790,053 on 11 March 1905; it is dated 16 May 1905. The cage has a lower rim or bar 2 carrying the upright wires 3; hooks 7 on the flange receive the rim, and slides 8 on the flange pass over it to interlock cage and base. The pan 9 has a front 10 with an inward upper edge 11 and a knob 12. He noted that the rim and flange also give a finished look and allow a flat base, where cages with a drawer in the base must be deep. His claims cover the base with its rim and flange, the cage set within it, and the pan extending beneath the flange, with its front completing the fourth side. **Honest limits.** A screwed aluminium rim on a board and a bought cage stand in for his; wire hooks replace his hooks and slides. The notebook assumes refuse falls evenly; its sizes are examples. Your lentil counts are the result.
