Abstract
Abstract An air cooler and cleaner for a truck cab or the like formed as a comparatively flat, box-like unit adapted to be mounted upon the top of a truck cab. Air flowing into this cooler will move through a rotating, cylindrical filter and thence through a duct and into the vehicle cab. A reservoir is provided in the lower portion of the cooler through which the cylindrical filter moves to continuously wet and wash the fibers thereof.

Claim 1
Independent Claim
367 words
An air conditioning apparatus for a vehicle cab, or the like having a substantially flat roof and an opening in the roof, said apparatus being adapted to be mounted upon the roof over the opening to deliver cool, clean and humidified outside air through the roof opening and into the cab, wherein said air conditioning apparatus includes: a. an enclosed, comparatively-flat, box-like housing including walls, a top and a floor and being adapted to be partially filled with water to a selected level, with the upper portion forming an air passageway above the water level; b. an intake in the wall of the housing, at one side thereof, to receive outside air, c. an air discharge tube within the housing near the wall opposite the intake, said tube upstanding from the floor of the housing to extend to the air passageway above the water level, said tube being in registration with the aforesaid cab roof opening to permit air to flow from the housing, downwardly through the tube and into the cab; d. a cylindrical, horizontal, foraminous filter drum within the housing between the intake and the discharge, with the ends of the drum extending to opposite walls of the housing, the top cylindrical surface of the drum being at the top of the housing and the lower portion of the drum being in the lower portion of the housing below the water level whereby the drum blocks the air passageway and forces all air flowing through the passageway to flow through the drum; e. a horizontal baffle means within the housing at the discharge side of the filter drum in spaced parallelism with the floor, at the said selected level to form the bottom surface of said air passageway, said baffle extending from the walls of the housing to the filter drum with the discharge tube extending upwardly and through this baffle means Whereby to prevent water below the baffle means from splashing into the discharge tube; f. a means for slowly rotating the drum to move wetted portions at the bottom of the cylinder from below the water level to traverse the air passageway; and g. air-moving means adapted to move air through the apparatus.

An air conditioning apparatus for a vehicle cab, or the like having a substantially flat roof and an opening in the roof, said apparatus being adapted to be mounted upon the roof over the opening to deliver cool, clean and humidified outside air through the roof opening and into the cab, wherein said air conditioning apparatus includes: a. an enclosed, comparatively-flat, box-like housing including walls, a top and a floor and being adapted to be partially filled with water to a selected level, with the upper portion forming an air passageway above the water level; b. an intake in the wall of the housing, at one side thereof, to receive outside air, c. an air discharge tube within the housing near the wall opposite the intake, said tube upstanding from the floor of the housing to extend to the air passageway above the water level, said tube being in registration with the aforesaid cab roof opening to permit air to flow from the housing, downwardly through the tube and into the cab; d. a cylindrical, horizontal, foraminous filter drum within the housing between the intake and the discharge, with the ends of the drum extending to opposite walls of the housing, the top cylindrical surface of the drum being at the top of the housing and the lower portion of the drum being in the lower portion of the housing below the water level whereby the drum blocks the air passageway and forces all air flowing through the passageway to flow through the drum; e. a horizontal baffle means within the housing at the discharge side of the filter drum in spaced parallelism with the floor, at the said selected level to form the bottom surface of said air passageway, said baffle extending from the walls of the housing to the filter drum with the discharge tube extending upwardly and through this baffle means Whereby to prevent water below the baffle means from splashing into the discharge tube; f. a means for slowly rotating the drum to move wetted portions at the bottom of the cylinder from below the water level to traverse the air passageway; and g. air-moving means adapted to move air through the apparatus.
Claim 3
Dependent Claim
28 words
In the apparatus defined in claim 1, wherein: a short portion of the tube extends below the floor of the housing and into the aforesaid cab roof opening.
Claim 4
Dependent Claim
84 words
In the air conditioning apparatus defined in claim 1, wherein: a. the aforesaid filter drum includes a sleeve mounted upon an open, reticulated wire frame and the sleeve includes a circumferential slot; b. said drum rotating means includes a hooked pawl extending into the slot with the hook thereof engaging one of the wire members of the reticulated drum frame; and c. a motor and crank means adapted to reciprocate the pawl to shift the hook thereof from one wire member to the next.
Claim 5
Dependent Claim
35 words
In the air conditioning apparatus defined in claim 1, wherein said baffle means includes: a splash baffle upstanding from the bottom of the housing between the filter drum and the duct constituting the discharge opening.
Claim 6
Dependent Claim
61 words
In the apparatus defined in claim 1, including: a second baffle means within the housing at the intake side of the filter drum in spaced parallelism with the floor thereof and at the said selected level, and extending from the walls of the housing to the filter drum to prevent water below the baffle means from splashing into the intake opening.
Claim 7
Dependent Claim
246 words
An air conditioning apparatus to clean and himidify outside air and discharge the same into a vehicle cab, or a like enclosure, and comprising: a. a housing structure adapted to be mounted upon the vehicle cab and having an intake opening to receive outside air, a discharge opening directed into the cab to discharge cleaned and humidified air therein, a passageway through the upper portion of the housing connecting the intake and discharge openings and a water reservoir below the passageway; b. a horizontal filter drum within the housing having an open reticulated wire frame carrying a generally cylindrical, foraminous sleeve, with the upper portion of the drum traversing the aforesaid passageway and with the lower portion of the drum being submerged in the water reservoir; c. air-moving means adapted to move air through apparatus, from the intake opening, through the passageway, through the drum in the passageway and from the discharge opening; d. a circumferential slot means in the sleeve exposing wires of the frame; and e. a drum rotating means for slowly rotating the drum to move wetted portions of the sleeve from the reservoir and to the passageway to expose wetted portions to air moving through the passageway including a hooked pawl extending into the slot with the hook thereof engaging one of the frame wires of the filter drum and a motor and crank means adapted to reciprocate the pawl to shift the hook thereof from one frame wire to the next.
