Abstract
Abstract A ventilating system for a livestock building includes a substantially enclosed building structure having a ceiling with an attic compartment above it and a livestock compartment below it. An elongated air conduit extends through the building structure substantially parallel to the ceiling and has at least one elongated slot extending substantially the length thereof. A fan or the like circulates air in the livestock compartment through the conduit and outwardly through the slot with a baffle adjacent the slot directing the air exiting therefrom upwardly towards the ceiling. An elongated opening in the ceiling in close proximity and parallel to the conduit is provided for bringing a source of fresh air into the livestock compartment and an air deflector is provided for mixing the fresh air with the circulated air passing through the slot.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
132 words
A ventilating system for a livestock building comprising, a substantially enclosed building structure having a ceiling with an attic compartment thereabove and a livestock compartment therebelow, an elongated air conduit extending through said livestock compartment substantially parallel to said ceiling, at least one elongated slot in said conduit extending substantially the length of said conduit, means for circulating the air in said livestock compartment through said conduit and outwardly through said slot, a baffle adjacent said slot for directing air exiting through said slot upwardly towards said ceiling, an elongated opening in said ceiling in close proximity and parallel to said conduit for bringing a source of fresh air into said livestock compartment, and means for deflecting air passing through said elongated opening for mixing with said air passing through said slot.
Claim 2
Dependent Claim
132 words
A ventilating system for a livestock building comprising, a substantially enclosed building structure having a ceiling with an attic compartment thereabove and a livestock compartment therebelow, an elongated air conduit extending through said livestock compartment substantially parallel to said ceiling, at least one elongated slot in said conduit extending substantially the length of said conduit, means for circulating the air in said livestock compartment through said conduit and outwardly through said slot, a baffle adjacent said slot for directing air exiting through said slot upwardly towards said ceiling, an elongated opening in said ceiling in close proximity and parallel to said conduit for bringing a source of fresh air into said livestock compartment, and means for deflecting air passing through said elongated opening for mixing with said air passing through said slot.
Claim 3
Dependent Claim
51 words
The ventilating system of claim 1 wherein said means for circulating the air in said livestock compartment comprises a fan means at one end of said conduit, said fan means adapted to direct air from said livestock compartment into one end of and through said conduit and outwardly through said slot.
Claim 4
Dependent Claim
47 words
The ventilating system of claim 1 wherein said building structure further comprises a generally continuous sidewall which cooperates with said ceiling to define an enclosure, said sidewall having an exhaust opening through which air in the livestock compartment is exhausted to the atmosphere outside the building structure.
Claim 5
Dependent Claim
23 words
The ventilating system of claim 3 further comprising an exhaust fan operatively connected to said exhaust opening for forcing the air outwardly therethrough.
Claim 6
Dependent Claim
40 words
The ventilating system of claim 1 wherein said baffle comprises and elongated flange connected to said conduit at a position below said slot and extended upwardly and outwardly therefrom to a position higher than and laterally spaced from said slot.
Claim 7
Dependent Claim
22 words
The ventilating system of claim 1 wherein said elongated opening in said ceiling is substantially coextensive in length with said air conduit.
Claim 8
Dependent Claim
68 words
The ventilating system of claim 1 wherein said means for deflecting air comprises an elongated deflector plate having a lower end secured to said air conduit and an upper edge positioned in clearance relation from said ceiling and laterally outwardly of said ceiling opening whereby fresh air from said ceiling opening is directed laterally through said clearance between said plate and ceiling and laterally therefrom along the ceiling.
Claim 9
Dependent Claim
32 words
The ventilating system of claim 1 wherein said air conduit comprises an elongated top wall, a bottom wall and opposite sidewalls, said slot being formed through a lower portion of one sidewall.
Claim 10
Dependent Claim
16 words
The ventilating system of claim 1 further comprising an air heater unit within said livestock compartment.
Claim 11
Dependent Claim
41 words
The ventilating system according to claim 1 comprising two of said elongated slots, two baffles adjacent said respective slots, two ceiling openings on opposite sides of said air conduit and two means for deflecting air passing through said respective ceiling openings.
Claim 12
Independent Claim
97 words
The method of ventilating a substantially closed livestock building having a ceiling with an attic compartment thereabove and a livestock compartment below, comprising moving ambient air within the building in a substantially horizontal direction through a conduit adjacent said ceiling, exiting at least some of said moving ambient air upwardly outwardly from said conduit towards said ceiling in a substantially continuous sheet, introducing fresh air from outside said building through said attic and through said ceiling in a substantially continuous sheet substantially parallel to and adjacent said ceiling, and mixing said sheets of ambient and fresh air.
Claim 13
Independent Claim
97 words
The method of ventilating a substantially closed livestock building having a ceiling with an attic compartment thereabove and a livestock compartment below, comprising moving ambient air within the building in a substantially horizontal direction through a conduit adjacent said ceiling, exiting at least some of said moving ambient air upwardly outwardly from said conduit towards said ceiling in a substantially continuous sheet, introducing fresh air from outside said building through said attic and through said ceiling in a substantially continuous sheet substantially parallel to and adjacent said ceiling, and mixing said sheets of ambient and fresh air.
Claim 14
Dependent Claim
32 words
The method of claim 11 wherein said sheets of ambient and fresh air are mixed in sufficient proportions to maintain a substantially uniform temperature gradient throughout the height of said livestock compartment.
Claim 15
Dependent Claim
35 words
The method of claim 11 wherein said sheets of ambient and fresh air are mixed adjacent said ceiling in sufficient proportions to maintain a substantially uniform temperature gradient throughout the height of said livestock compartment.
Claim 16
Dependent Claim
38 words
The method of claim 11 wherein said sheets of ambient and fresh air are mixed in sufficient proportions to maintain a substantially uniform temperature gradient throughout the height of said livestock compartment within a variation of 2° F.
Claim 17
Dependent Claim
17 words
The method of claim 11 wherein said fresh air is introduced through said ceiling adjacent said conduit.
