Abstract
Abstract A ventilating and temperature control system for a closed, rectangular swine house, the swine house having a manure sump filled with water disposed centrally and longitudinally therein. Air inlets, with suitable baffles, are formed longitudinally through the sidewalls into the swine house proximate the juncture of the sidewalls and the roof and a plurality of air outlet ducts are formed through the roof in space-apart relation over the manure sump. The ducts extend downwardly of the roof and are equipped with blowers. The blowers are electrically connected into at least two separate, thermostatically controlled, electrical circuits.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
A ventilating and temperature control system for a closed shelter house having a floor, sidewalls, and a roof, the ventilating and temperature control system comprising: a manure sump formed in the floor of the shelter house and adapted to be filled with water; air inlet means formed into the shelter house proximate the juncture of the sidewalls and the roof; baffle means proximate said air inlet means; a plurality of air outlet means formed through the roof of the shelter house over said manure sump, said air outlet means extending downwardly of the roof; blower means mounted in each air outlet means for forcing air out of the shelter house, said blower means being electrically operated and connected in at least two electrical circuits, a first part of said blower means being controlled by first electrical circuit means to operate on a periodic basis regardless of the temperature in the shelter house, and a second part of said blower means being controlled thermostatically.
Claim 2
Dependent Claim
163 words
A ventilating and temperature control system for a closed shelter house having a floor, sidewalls, and a roof, the ventilating and temperature control system comprising: a manure sump formed in the floor of the shelter house and adapted to be filled with water; air inlet means formed into the shelter house proximate the juncture of the sidewalls and the roof; baffle means proximate said air inlet means; a plurality of air outlet means formed through the roof of the shelter house over said manure sump, said air outlet means extending downwardly of the roof; blower means mounted in each air outlet means for forcing air out of the shelter house, said blower means being electrically operated and connected in at least two electrical circuits, a first part of said blower means being controlled by first electrical circuit means to operate on a periodic basis regardless of the temperature in the shelter house, and a second part of said blower means being controlled thermostatically.
Claim 3
Dependent Claim
112 words
The ventilating and temperature control system of claim 1 wherein: said shelter house is rectangular; said manure sump is formed centrally and longitudinally of the shelter house and extends for substantially the entire length thereof; said air inlet means extend substantially the entire length of the shelter house along both sides and include openings on the interior of the shelter house facing the floor; and said baffle means includes means suspended below and proximate said openings and having a width greater than the width of said openings and being adapted to adjustably distribute incoming air partially down along the interior walls of the shelter house and partially away from the interior sidewalls.
Claim 4
Dependent Claim
77 words
The ventilating and temperature control system of claim 2 wherein: said manure sump is formed by two longitudinal, spaced-apart sidewalls extending downwardly of the floor of the shelter house; two lateral, spaced-apart endwalls extending downwardly of the floor of the shelter house and abutting the longitudinal sidewalls; and a sump floor sloping to one end of said shelter house; and wherein said sump is covered by a slatted framework level with the floor of the shelter house.
