Abstract
Abstract The combination machine is used both as a fire extinguisher and an air blower. Primarily, it consists of a back-pack or other type unit having an internal combustion engine powering a blower. It includes one hose coupled to a pivotal exhaust pipe cover and to the air inlet of the blower, and the hose pipes exhaust gas into the blower when such gas is needed to extinguish a fire. A second hose is provided and is coupled to the blower at one end and is secured to a sleeve fastened to an air cooled cone or nozzle which is used to blow air or exhaust gas, whenever needed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A combination exhaust gas fire extinguisher and blower machine, comprising an internal combustion engine, a blower coupled to said engine, an engine housing receiving said engine, a blower housing receiving said blower and secured to said engine housing, a pivotal cover secured to said engine housing, for covering and uncovering the exhaust pipe area of said engine, a flexible control cable secured to said pivotal cover, for the operator to switch from blower operational function, to fire extinguishing function, a first flexible hose secured to said pivotal cover and to said blower, and a second flexible hose secured to an air cooled cone and said blower.
Claim 2
Dependent Claim
106 words
A combination exhaust gas fire extinguisher and blower machine, comprising an internal combustion engine, a blower coupled to said engine, an engine housing receiving said engine, a blower housing receiving said blower and secured to said engine housing, a pivotal cover secured to said engine housing, for covering and uncovering the exhaust pipe area of said engine, a flexible control cable secured to said pivotal cover, for the operator to switch from blower operational function, to fire extinguishing function, a first flexible hose secured to said pivotal cover and to said blower, and a second flexible hose secured to an air cooled cone and said blower.
Claim 3
Dependent Claim
92 words
The combination as set forth in claim 1, wherein said exhaust pipe extends from an opening provided through a cover plate secured to said engine housing, and an open end of said pivotal cover is secured by a hinge to said cover plate and the rim of said open end of said pivotal cover engages with the outer surface of said cover plate and prevents the escape of said exhaust gas from said exhaust pipe, except through said first flexible hose which is suitably secured in an opening through said pivotal cover.
Claim 4
Dependent Claim
64 words
The combination as set forth in claim 2, wherein said pivotal cover is opened and closed by said flexible control cable which includes a knob on one end for being held by an operator, and the opposite end of said first flexible hose is secured within a central opening provided through a blower plate secured over an air inlet opening through said blower housing.
Claim 5
Dependent Claim
60 words
The combination as set forth in claim 3, wherein said exhaust gas is piped from within said pivotal cover into said first flexible hose and into the air inlet opening through said blower housing, and said blower blows said gas out of said second flexible hose which is suitably secured in an opening through one face of said blower housing.
Claim 6
Dependent Claim
30 words
The combination as set forth in claim 4, wherein said second flexible hose is also secured to a sleeve having a handle fixedly secured for holding said second flexible hose.
Claim 7
Dependent Claim
117 words
The combination as set forth in claim 5, wherein a hollow cone is secured to said sleeve by a set screw and cooling fins are provided on said cone at its smaller diameter portion for cooling of said exhaust gas as said gas leaves said cone onto a fire, and further cooling is provided by louvers pivotally received within openings through said blower plate and said louvers are of the spring-return type that enables the openings through said blower plate to normally remain covered and when said machine is operated, the speed of said engine governs the degree of opening of said louvers which enables inlet air entry into said blower for cooling of said exhaust gas.
