Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wood-stove smoke controller and more particularly pertains to a new woodstove emission controller for conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.
2. Description of the Prior Art
The use of wood-stove smoke controller is known in the prior art. More specifically, wood-stove smoke controller heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 4,280,476; 4,510,854; 4,424,799; 4,708,123; U.S. Pat. No. Des. 266,867; and U.S. Pat. No. 4,469,284.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new woodstove emission controller. The inventive device includes a tubular member having an inlet end, an outlet end and a bore extending therethrough; and also includes a closure member securely disposed in the bore near the outlet end for preventing a back-draft of emissions; and further includes a fan member securely and rotatably disposed in the bore for drawing emissions in through the inlet end and out through the outlet end of the tubular member; and also includes a motor mounted to the exterior of the tubular member, a belt member carried by the motor and the fan member, and a switch for energizing the motor.
In these respects, the woodstove emission controller according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to
FIGS. 1 through 2
thereof, a new woodstove emission controller embodying the principles and concepts of the present invention and generally designated by the reference numeral
10
will be described.
As best illustrated in
FIGS. 1 through 2
, the woodstove emission controller
10
generally comprises a tubular member
11
having an inlet end
13
, an outlet end
12
and a bore
14
extending therethrough and being adapted to be securely mounted in a pipe
33
of the wood-stove. A closure member
16
is securely mounted in the bore
14
of the tubular member
11
near the outlet end
12
for preventing a back-draft of emissions. The closure member
16
includes a spindle
17
having ends which are securely disposed in a side wall
15
and to either side of the bore
14
of the tubular member
11
, and further includes a pair of flap members
18
,
19
each having an end which is hingedly mounted to the spindle
17
for preventing a back-draft of emissions. Each of the flap members
18
,
19
is semi-circular shaped with the flap members
18
,
19
being adapted to close the bore
14
. A fan member
20
is securely and conventionally disposed in the tubular member
11
for drawing smoke through the pipe
33
. The fan member
20
includes a cylindrical frame
21
having a top ring member
22
, a bottom ring member
23
, a plurality of blade members
24
disposed parallel to a longitudinal axis of the tubular member
11
and securely and conventionally interconnecting the top ring member
22
to the bottom ring member
23
and being spaced along a circumference of the cylindrical frame
21
. The fan member
20
further includes a cross member
25
having ends securely attached and welded to the bottom ring member
23
. The fan member
20
also includes a shaft member
26
securely attached and welded to the cross member
25
and extending co-axially of the tubular member
11
with the fan member
20
being essentially a centrifugal fan which draws emissions in through the inlet end
13
and out through the outlet end
12
of the tubular member
11
. A means for actuating and driving the fan member
20
includes a housing
27
which is securely and conventionally mounted to an exterior of the side wall
15
of the tubular member
11
, and further includes a motor
28
being securely and conventionally disposed in the housing
27
and having a motor shaft
29
, and also includes a belt member
30
being carried by the motor shaft
29
and the shaft member
26
, and further includes a switch
31
for energizing the motor
28
. The switch
31
includes a power cord
32
which is adapted to be plugged into a power source with the switch
31
being a thermostatic switch.
In use, the user turns on the switch
31
which energizes the motor
28
which turns the shaft member
26
which turns the fan member
20
thus causing the fan member
20
to draw the emissions in through the inlet end
13
and out through the outlet end
12
of the tubular member
11
. In the alternative, the motor
28
would be energized by the thermostatic switch
31
when the temperature in the bore
14
of the tubular member
11
reaches a certain temperature.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
