Improvements in Carburetors.
I, CHARLES RUSSELL COLLINS, of 1828, North Sixteenth Street, in the City
of Philadelphia, in the County of Philadelphia in the State of Pennsylvania, one
of the United States of America, Engineer, do hereby declare the nature of my
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to the construction of carburetors such as are used in water
gas plants for enriching the water gas, and my object is to provide a carburetor of
efficient and durable construction. This I accomplish by means of the devices
hereinafter described in connection with the drawings which show my carburetor
in central vertical section together with other parts of a gas making apparatus.
In the drawings, A, represents a gas generator; B, the carburetor; C, a fixing
chamber; D, the stack; E, the washer for the gas. All these parts except the
carburetor are of familiar construction and need not be further described, save to
point out, that a conduit F having a valve at G leads from the generator into an
anuular chamber H formed in the carburetor B around an interior chamber K
open at the bottom and top as shown and filled with checker-work J of the
ordinary kind, that is, of brick. I, in a conduit opening into the bottom of the
carburetor and leading from the generator. The conduit F being preferably used
for the producer gas formed in blowing up, and the conduits I and F at will for
the water gas.
G and G' indicate valves in conduits F and 1, and I, is an air
blast opening. At the top of the chamber K is an enlarged chamber L also
filled with checker work as shown at J and M, the upper layer, M, being of iron,
and the depth of the iron checker-work being such as will insure that no fluid oil
will pass beyond it (in the construction shown below it) and come in contact with
the brick checker-work. This forms an important feature of my invention, and
makes my carburetor much more durable, as the oil, when it comes in direct
contact with the brick work has a disintegrating effect and rapidly destroys it.
N, is the oil injector situated next to the iron checker work; O, a conduit,
leading into the fiting chamber C, also filled with checker work. P, a conduit
leading to the washer E through the pipe S or to the stack Q, which is provided
with a valve indicated at R.
In practice, the generator is blown up, the valve G¹ being closed, the gases
passing through conduit F into annular passage H serving to heat the walls of
chamber K, and then being mixed with air from I', and ignited, it passes up
through chambers K, L, conduit O, chamber C, conduit P and stack Q to the
atmosphere. When water gas is being made, valve G is closed and G₁ opened,
or G' closed and G opened as may be desired, and the gas enters the carburetor
through conduits I or F passing up through the heated checker-work in
chambers K and L, and the injector N at the same time throws a spray of oil
down on the iron checker-work, which serves to vaporize it together with the
action of the hot gas. The vapor and gas pass together to the fixing chamber C,
and thence to the washer, the valve R being closed.
The advantage of the spiral construction of the carburetor with respect to the
chambers H and K is not only, that the entering gas serves to heat the interior
chamber, but also that the gas conduit F can be and is made very short, and very
little heat lost by radiation."
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
First. In a carburetor the combination with the shell of a carburetor, an oil

page_text: injector and a checker work filling, consisting of a portion M formed of iron and
situated in that part of the casing where the oil enters, and a portion J, formed of
brick situated at a distance from the oil entrance, all substantially as specified and
whereby the brick checker-work is preserved from the destructive action of
the oil.
Second. A carburetor B having in combination a central chamber K filled with
checker work, an annular gas passage H formed around said chamber, a broadened
chamber L situated above the chamber K and also filled with checker work, and
an oil injector N at the top of chamber L.
