page_text: COMPLETE SPECIFICATION.
I, LOUIS ANTOINE VICTOR PELLEGRIN of 2 Chadstone Villas, Lebanon Gardens
Wandsworth in the County of Surrey Civil Engineer do hereby declare the
nature of my invention for "IMPROVEMENTS IN APPARATUS FOR CARBURETTING
" and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
AIR
My Invention consists in the use of a self acting and regulating distributor for
allowing the admission of a quantity of gasoline in proportion to a given quantity
of air and in the use of "check-partitions" in order to increase the evaporating
surface so as to ensure the complete evaporation of the liquid, whatever may be the
temperature of the air.
The apparatus consists of an ordinary aspirator or air compressor A actuated by
weights as shown in the accompanying drawing of which Figure I is an elevation,
Figure II a plan and Figure III a section of the regulating tube T to an enlarged
scale.
B is a regulating gas holder; C an evaporating chamber, D a self regulating.
distributing Apparatus. The gas holder B is an ordinary one such as used for any
other gas. It has no special feature.
The evaporating Chamber C is fitted with a series of iron Sheets S covered with
Cotton, blotting paper or any other suitable material.
These partitions are so arranged that the whole of the Surface is licked by the
air coming from the aspirator.
They check the passage of the gasoline and compel it to run from one upon the
other in order to increase and facilitate the evaporation. For those reasons I call
those partitions "check partitions."
The regulating and distributing apparatus is composed of a Slide Valve D
through which the liquid passes from the tank H, through the tube G into the
Chamber F and from there into the evaporating chamber C through the tube I.-
At each revolution of the fan Spindle the Slide valve is open, and a certain
quantity of gasoline is admitted to pass through it, as shown by fig 4.

page_text: The Speed of the fan Spindle being regulated by the quantity of gas consumed,
the feeding of the gasoline required to produce such quantity of gas is thus regulated
automatically.
The air entering the aspirator A is forced into the holder B and from there into
the bottom of the Chamber C through the tube L and then to the tube R and the
pipes.
The regulating tube acts as follows:
The quantity of gasoline that must be admitted at each revolution of the fan
Spindle is regulated before hand by setting the tube T. in the proper position in the
Chamber F.
This quantity varies with the size of the machine and is regulated by testing.
The tube T being fixed to a certain depth in the chamber F, when the gasoline
admitted through the tube G reaches the tube T it raises a small float Z. which
closes the end of the tube T and thus preventing the air and liquid from escaping,
stops the admission of the gasoline.
The Slide D, then being lowered by the action of the fan Spindle, forms a
connection between the chamber F and the tube I, allowing the gasoline to drop
from the Chamber F into the check Chamber C, through the tube or channel G.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1st The use of evaporating "check partitions" to increase the evaporating
surface.
.
2d The use of an adjustable regulating and distributing arrangement, which, by
admitting the required quantity of gasoline to obtain a perfect Carburetting of the
air, renders the Apparatus perfect whatever be the temperature of the air and the
number of burners in actual use.
