Abstract
Abstract A portable air compressor housing including a main, open frame adapted to support an air compressor for movement over the ground surface via wheels suspended from the frame. The air compressor apparatus is enclosed by housing structure including opposite end pieces upstanding from the frame and interconnected by an elongated ridge pole from which are hinged folding doors providing full access to the air compressor parts. Below the folding doors, on opposite sides of the housing, are tool box compartments which also close the sides and ends of the housing. The bottom walls of the tool boxes are formed by an open mesh to permit hot air to escape from the housing through the mesh. The open tool box bottoms provide restrictions for the air flow and also aid in establishing a circuitous air flow pattern through the housing resulting in dissipation of sound and consequent reduction of noise. Further noise reduction may be achieved by baffles mounted on the opposite ends of the frame as well as a baffle mounted below the compressor structure in a horizontal plane under the opening in the main frame. To further reduce noise, the folding doors may be provided with sound absorption panels on the inner sides thereof.

Claim 6
Dependent Claim
47 words
The housing defined in claim 1 wherein said main frame includes a plurality of generally parallel side members, and a bumper fixed to and cross the ends of said side frame members, and wherein said end pieces include leg portions fixed to the opposite side members respectively.
Claim 7
Dependent Claim
25 words
The housing defined in claim 1 wherein said door units include acoustical panels fixed on the inner sides thereof for absorbing sound to reduce noise.
Claim 8
Dependent Claim
162 words
A housing for apparatus such as an air compressor and the like; the housing including a main frame adapted to support the air compressor and associated parts, a pair of end pieces fixed to and upstanding from opposite end portions of the main frame, an elongated ridge pole extending longitudinally over the main frame and interconnecting said end pieces, and a pair of door units hinged to opposite sides of said ridge pole for movement between a closed position overlying top and side portions of the interior of the housing and an open position providing access to said interior portions, and wherein said end pieces include two inverted generally L-shaped portions fixed to opposite sides of said ridge pole at the opposite ends of the ridge pole respectively, said L-shaped portions including vertical leg portions, and wherein said end pieces further each include a grill assembly including a plurality of elongated rods extending between the opposite leg portions of said end pieces.
