Ventilated rack and animal cage system
First Claim
1. An animal cage system comprising:
- at least one cage having a top section and a bottom section that supports said top section at a periphery;
a rack for supporting said cage; and
,an air supply means including an air input means for supplying air to said cage and an air removal means for removing air from the periphery of said cage; and
a spacer bracket located between said top and bottom sections of said cage for separating said top and bottom sections to allow air to be removed from said periphery to an exhaust port after said air has circulated through said cage.

Abstract
An animal cage rack includes a forced air system for removing air from the periphery of the animal cages. The rack includes "U" shape guides for positioning and aligning each cage with respect to a positive ventilating probe and an automatic watering device. Each cage includes a top bonnet section, a bottom section which supports the bonnet around the periphery thereof, a flat rim wire bar lid, and a filter in the bonnet. An L-shaped spacer separates the bonnet from the bottom section so that air exhaust ports in the U-shaped guide can remove exhausted air from the periphery of the cage. Positive air supplied by an air inlet manifold is introduced through an aperture in the bonnet and the L-shaped bracket, to the top of each cage. A downwardly facing port in the air tube forces air toward the bottom of the cage which after it circulates is removed through the periphery by the exhaust ports in the U-shaped cage guides.

8. An animal cage apparatus for use in a rack having an air supply and an air exhaust manifold, said apparatus comprising:
-
a top section means for receiving air from said air supply manifold; a bottom section means for supporting said top section means at the periphery thereof; and a spacer means for spacing said top and bottom section means apart so that air can be removed from said periphery by said air exhaust manifold. - View Dependent Claims (9, 10)

11. An animal cage system comprising:
-
at least one cage having a top section and a bottom section that supports said top section at a periphery, said top section having an aperture therein; a rack for supporting said cage; an air supply means including an air input means for supplying air to said cage and an air removal means for removing exhaust air from the periphery of said cage; said air input means including a positive air inlet manifold and an air tube connected to said positive air inlet manifold, said air tube supplying air to said cage through said aperture in said top section and said air tube including a port therein which points in the direction of said bottom section of said cage so that air supplied to said cage is direction towards the bottom of said cage. said air removal means including a negative pressure air exhaust manifold and at least one air exhaust port located near the periphery of said cage, so that said exhaust air is removed from said cage by said exhaust port after said air has circulated through said cage; and a spacer bracket located between said top and bottom sections of said cage for separating said top and bottom sections to allow said exhaust air to pass from said periphery to said exhaust port, said spacer bracket having a top section and a bottom section and a generally L-shape, wherein said top section of said bracket includes an aperture through which said air tube passes when said cage is located in said rack.

16. An animal cage apparatus for use in a rack having an air supply and an air exhaust manifold, said apparatus comprising:
-
a top section means for receiving air from said air supply manifold; a bottom section means for supporting said top section means at the periphery thereof said cage having a front and rear section; and
,a spacer means for spacing said top and bottom section means apart so that air can be removed from said periphery by said air exhaust manifold, said spacer means including a bracket having a top portion and a bottom portion and a generally L-shape, said bottom portion of said spacer bracket locatable at the periphery between said top and bottom section means at said rear section of said cage and including projections thereon to assist in separating said top and bottom section means, wherein the top portion of said spacer bracket includes an aperture therethrough through which air from said air supply means passes. - View Dependent Claims (12, 13, 14, 15, 17, 18)
