JOHN W. HOOSER, OF DALLAS, TEXAS.
CARBURETING SYSTEM FOR INTERNAL-COMBU.STION ENGINES.1,217,448.
.Specification of Letters Patent.
Patented Feb. 27, 1917.
Application filed January 16, 1917. Serial No.-"T42,678.
To all whom it may concern:
Be it known that I, JOHN W. HOOSER, a
citizen and resident of Dallas, county of
Dallas; State of Texas, and United States
5 of America, have invented certain new and
useful Improvements in Carbureting .Sys-.
tems for Internal-Combustion Engines.
This invention relates to a new and useful
form of carbureter adaptable for use on
10 internal combustion motors and is conceived
and designed for vaporizing fuel oils of the
heavier .and non-volatile class for combus-
. tion in the engine.
A further purpose of the invention is to
15 provide a carbureting system for automobile
engines which will produce a resulting gas
of such a quality as will give perfect com-
bustion.
The carbureting device constituting this
20 invention, an example of which is disclosed
in. this Letters Patent, particularly apper-
tains to a thermal carbureting system for var:
porizing, through the agency of heat from
the running motor, oils of low specific gray-
25 'ity such as that grade of oil which is known.
and sold in the market as coal oil. The ther-
mal carbureter included in this invention
provid.es'means for mixing with the coal-oil
vapor a light steam vapor, which water va-
30 por or steam is passed ,to and thoroughly
. intermixed with a combustible vaporized'
mixture prior to combustion in the cylinder
of the engine. Thisprovision of tl.e. vapor
used in' connection with the hydrocarbon oil*
35 vapor softens and tones down the combus-'
tible mixture to a. degree which is most effi-
cient and thoroughly combustible in explo'
sion chamber.at .the point, of highest com-
pression, for the reason that the explosive
40 mixture. combined with the humid water
vapor' cuts and disintegrates the carbon.
which would otherwise form at the point
of combustion within the cylinder and cause
the explosion chamber and all -parts asso-
45 ciated therewith, including the spark plug
of the engine, to be thoroughly cleaned, and
scoured at the point of pressure of the power*
impulse delivered by the. comparatively
quick and cleansing explosion of the said
50 mixture.
With the above and other objects in view
the invention has relation to a certain com-
bination and arrangement of parts, an ex-
ample of which is described in the following
55 specification pointed out in the appendedclaims, and illustrated in the accompanying
drawings; wherein,
Figure 1 is a view of the carbureting sys-
tem in its entirety shown in' side elevation
with many parts in section and which device 60
is shown in position on a diagrammatical
form of gas engine or automobile motor.
Fig. 2 is a cross sectional view taken
through one of. the mianifolds included in
the invention and shows in form the general 65.
shape and construction of said.manifold..
Referring now more in particular to the
drawings, wherein the' same parts are des-
ignated by the same .reference characters
throughout the views, the numerals 1 and '70
2 point out a certain form of duplex gen-
erating manifold.' This form of generating
manifold comprises an exterior substantially
large exhaust duct 1 which is provided with
the usual exhaust receiving ports 3 opening 75
directly into the said . manifold and con-
necting with the exhaust ports leading from
thecylinder of theengine. "The manifold will.
preferably. be formed tapering in design,.
enlarging from one end to the other as the 80
volume of heated gases entering the'-man -
fold increase, that they . may be readily
passed, - without back pressure, from the
motor cylinders. The internal manifold 2
is' preferably. formed and cast integrally 85
with the part 1, and is provided with con-
necting flanges-4, or any suitable means for
effecting' connection'with other parts. The
internal manifold 2 may be formed' with a
tapering design similar to the exhaust mani- 90
fold, and is arranged in the central portions
of said exhaust manifold. The usual form
of intake manifold or duct 5 is provided
with ports 6' for connecting with the intake
ports of the cylinders. A connecting tube 95
7 is employed to connect the generating man-
ifold with the intake manifold 5 and is: of
sufficient size to adequately carry the gases
from the manifold 2 to the engine. . The
usual form of -carbureter 8 may be employed 100
and is connected to one extremity of the in-
ternal manifold.2 and is provided with fuel
supply pipe 9 which furnishes the carbu-
reter with a constant flow of coal oil or other
fuel to be used. An air' intake valve 10 105
equipped with a dash regulating mean 11
is 'connected with the nanifold .7 or at a
point 'in the ducts after carburization has
been effected.' This air intake valve. is em-
ployed for the purpose of admitting air. to 110
