Abstract
Abstract An exhaust scavenger system associated with industrial internal combustion engines for scavenging the atmosphere in vicinity of the engine and transporting any combustibles to a remote location. The system includes an elongated tubular housing having a concentrically arranged exhaust pipe affixed therein, with means for regulating the mass flow of gases ingested through the annulus formed between the exhaust pipe and its housing. A gas deflector means is affixed to the terminal end of the exhaust pipe and located within the housing so as to increase the efficiency of the scavenging action of the apparatus.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
Exhaust scavenger system for industrial internal combustion engines comprising: an elongated tubular housing, an exhaust pipe; means forming an air intake port; and means forming an exhaust gas deflector; said elongated tubular housing having an inlet end and an outlet end; said exhaust pipe having an inlet end and an outlet end with said inlet end adapted to be connected to the exhaust manifold of an internal combustion engine; said exhaust pipe being concentrically arranged within and longitudinally disposed with respect to at least part of said housing; said air intake port forming a marginal portion of the inlet end of said housing; said air intake port includes radially spaced apart apertures circumferentially disposed about said housing; and, means for regulating the effective area of the ports; said gas deflector being affixed to the outlet end of said exhaust pipe and within and in close proximity to the outlet end of said housing; and means for supporting at least part of the weight of said exhaust pipe from said housing; said means for supporting said exhaust pipe from the interior of said housing includes spaced apart heat transferring rods; said rods having one end portion thereof placed in slidable contact with the interior of said housing while the remaining end portion thereof is attached to the exterior of said exhaust pipe.
Claim 2
Dependent Claim
221 words
Exhaust scavenger system for industrial internal combustion engines comprising: an elongated tubular housing, an exhaust pipe; means forming an air intake port; and means forming an exhaust gas deflector; said elongated tubular housing having an inlet end and an outlet end; said exhaust pipe having an inlet end and an outlet end with said inlet end adapted to be connected to the exhaust manifold of an internal combustion engine; said exhaust pipe being concentrically arranged within and longitudinally disposed with respect to at least part of said housing; said air intake port forming a marginal portion of the inlet end of said housing; said air intake port includes radially spaced apart apertures circumferentially disposed about said housing; and, means for regulating the effective area of the ports; said gas deflector being affixed to the outlet end of said exhaust pipe and within and in close proximity to the outlet end of said housing; and means for supporting at least part of the weight of said exhaust pipe from said housing; said means for supporting said exhaust pipe from the interior of said housing includes spaced apart heat transferring rods; said rods having one end portion thereof placed in slidable contact with the interior of said housing while the remaining end portion thereof is attached to the exterior of said exhaust pipe.
Claim 3
Dependent Claim
75 words
The system of claim 1, and further including a flange; the inlet end of said exhaust pipe and said housing are attached to said flange; said flange having a centrally located aperture which forms the inlet end of said exhaust pipe; said radially spaced apart apertures being circumferentially aligned with one another and further includes a circumferentially extending skirt slidably received about said housing so that the skirt can be moved to cover said apertures.
Claim 4
Dependent Claim
75 words
The system of claim 1, wherein said outlet is located above said inlet; said gas deflector being a cone shaped member having a major diameter less than the internal diameter of said housing, said cone having the apex thereof concentrically arranged with respect to the exhaust pipe and located adjacent to and spaced apart from the exhaust pipe outlet; and means for adjusting the spaced apart distance of the cone relative to the exhaust pipe.
Claim 5
Dependent Claim
75 words
The system of claim 1, wherein said outlet is located above said inlet; said gas deflector being a cone shaped member having a major diameter less than the internal diameter of said housing, said cone having the apex thereof concentrically arranged with respect to the exhaust pipe and located adjacent to and spaced apart from the exhaust pipe outlet; and means for adjusting the spaced apart distance of the cone relative to the exhaust pipe.
Claim 6
Dependent Claim
79 words
The system of claim 1, wherein said gas deflector includes means by which it is adjustably disposed in spaced apart relationship with respect to the exhaust outlet; said deflector including a cone having an apex adjacent to said exhaust outlet and a base adjacent to said housing outlet; whereby: said deflector causes exhaust gases to flow into close proximity of the interior wall surface of the housing at an area closely adjacent to the outlet end of the housing.
Claim 7
Dependent Claim
53 words
The system of claim 5 wherein said cone includes a base; a band, means by which said band is slidably received about a marginal terminal end of said exhaust pipe, and said means by which said gas deflector is adjustably disposed includes a plurality of members attached to said base and said band.
Claim 8
Dependent Claim
38 words
The system of claim 5 wherein the outlet end of said housing is formed into a peripheral edge portion which is disposed relative to the central longitudinal axis of the housing at an angle substantially less than 90*.
