GUS BARTMAN, OF ROCKWALL, TEXAS.
ACETYLENE-GAS GENERATOR.
SPECIFICATION forming part of Letters Patent No. 654,781, dated Xily 31,1900.
Applicationflled Jly 31,1899. Serial No. 725,692 (No model)To all whom mit in~ay Oacei Z
Be it known that I, GUs HARTMAN, a citizen
of the United States, residing at Rockwall,
county of Rockwall, and State of Texas, have
5 invented a certain new and useful Improve-
ment in Acetylene-Gas Generators, of which.
the following is a specification.
My invention relates to a new and useful
improvement in acetylene-gas generators, and
io has for one object to provide an exceedingly-
simple apparatus of this description in which
the pipes and connections are closed, and thus.
protected from freezing by the effects of at-
ihospheric changes; and a further object of
15 my invention is to remove the possibility of
an explosion taking place during the nianipu-
lation of the machine.
A further object of my invention is to so
construct the apparatus as to greatly facili-
2o tate the recharging thereof in order that the
same may be accomplished in an exceedingly-.
short space of time; and a further object of
my invention is to accomplish; the results
aimed at without the use of float-valves or
25 other mechanism dependent upon the auto-
matic working of the apparatus for the gen-
eration of the g'as, while at the same time pro-
viding for the positive flow of water to the car-
bid, which is regulated by the amount of gas
3o generated and used.
With these and other ends in view this in-
vention consists in the details of construction
and combination of elements hereinafter set
forth and then specifically designated by the
35 claims.
In order that those skilled in the art to which
this, invention appertains may understand
how to make and use the same, the construc-
tion and operation will now be described in
40 detail, referring to the accompanying draw-
ings, forming a part of this specification, in
which--
Figure 1 is a vertical section of an appara-
tus made in accordance with my improve-
45 ment, showing-the various parts thereof; and
Fig. 2 a detail view of the gas-valve, showing
the relief-holes for permitting the escape of
the air in closing the carbid-chamber.
In carrying out my invention as here em-
5o bodied, I provide a gasometer A, which con-
sists of a cylindrical tank having the holder...B loosely fitted therein, so as to ride and fall
with the increase or decrease of the supply of
gas, and this holder is sealed in the usual man-
ner by the outer cylinder being nearly filled 55
with water, as clearly shown.
C represents the top of the holder and has
set in the center thereof the carbid-chamber
D, the latter having formed around its upper
portion an annular recess E by means of the 6o
casing F. This casing is secured to the top
C andto the carbid-chamber, so as to be gas-
tight. The carbid-chamber is closed when not
in use by the cap G, the flanges of which ex-
tend downward into the recess E, so as to seal 65
this chamber, which sealing is accomplished
by the mean&'of the rope or hemp packing I,
placed in the bottom of the recess and upon
which the edges of the flange of the cover rest,
while upon this packing is placed a certain 70
amount of sand I, and finally the remainder
of the recess is filled with water, as indicated
at J. By this arrangement gas generated
within the carbid-chamber cannot escape
therefrom through the sealing, since the watei 75
at J and the sand-bed cannot be disturbed, as
the packing IH prevents their displaceinent,
as will be readily understood. .The top C has
secured therein the pipe K, which leads from
the carbid-chamber and opens into the upper 8o
portion of the holder, so as to deliver the gas
thereto.
A housing"L partially surrounds .the lower
end of the pipe K-where it enters the carbid-
chamber and is so arranged as to admit gas 85
to this pipe only from the upper portion of
said chamber.
A valve K' is located in the pipe outside of
the apparatus and is operated by a lever K2,
which when the valve is open lies across the 90
cover G and against the knob J', so that said
cover cannot be removed until the lever is
elevated, which closes the valve, thus 'pre-
venting a forward flow of gas from the holder
to the carbid - chamber, and this, as is ob- 95
vious, will avoid the possibility of an. explo-
sion from the escape of gas from the appara-
tus when the cover is removed for 'recharg-
ing or other purposes. A suitable loop or
link is pivoted to the cover and adapted to 100
engage the outer end of the lever K2, thus
holding it in its horizontal position, and also
