Improvements in Acetylene Gas Generators.
I, EUGENE GODIN, of the City and District of Three-Rivers, Province of Quebec,
Canada, Electrician, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained,
in and by the following statement :—
This invention relates to apparatus for generating acetylene gas; and it consists
in the novel construction and combination of the parts hereinafter fully described
and claimed.
The drawing shows the apparatus in vertical section.
A is a vessel for holding the metallic carbide from which the gas is formed by
treating it with water in the usual manner.
B is a vessel for holding water, and C is a vessel which is open at the bottom
and supported in the lower part of the vessel B.
The vessel A. is provided with a removable cover a, and d is a gas pipe connected
to the cover a. A pipe c is connected to the pipe d and to the upper part of the
vessel C. A valve 6 is inserted in the pipe c.
A pipe c¹ is connected to the cover a and to the vessel C at a point below the pipe c.
D is an escape pipe connected to the lower part of the vessel C and passing out of
the vessel B a little below its top. A branch pipe d¹ is connected to the pipe d
for conducting the gas to wherever it is to be used.
The vessels B and C are filled with water to a little above the pipe c¹, and more
water is added from time to time so as to keep the water standing as nearly as
possible at a uniform level.
Water is admitted to the carbide by opening the valve b, and the valve 6 is also
opened. When too much gas is formed in the vessel A it passes down the pipe c
and depresses the water in the vessel C below the level of the pipe c¹ so that the
supply of water is cut off automatically.
The valve b¹ is used to close the pipe c when the cover a is raised to place more
carbide in the vessel A.
When a very large supply of gas is formed in the vessel A so that the water in
the vessel C is pushed down below the level of the escape pipe D, the surplus gas
escapes up the pipe D. The pipe D also serves for the escape of water should the
vessel B be filled too full.
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:
1. In apparatus for generating acetylene gas, the combination, with a vessel A
for holding metallic carbide, of a vessel B for holding water, an internal vessel C
open at the bottom and supported in the vessel B, a gas outlet pipe connected to
the upper parts of the vessels A and C, and a pipe connecting the vessel A with the
vessel C at a point below the said gas pipe, substantially as set forth.
2. In apparatus for generating acetylene gas, the combination with a vessel A for
holding metallic carbide, of a vessel B for holding water, an internal vessel C open

page_text: at the bottom and supported in the vessel B, a gas outlet pipe d connected to the
vessel A, a pipe c provided with a valve, and connected to the pipe d and to
the upper part of the vessel C, and a pipe c¹ provided with a valve and connected
to the vessel A' and to the vessel C at a point below the pipe c, substantially as set
forth.
