CHARLIE M. LINDHOLM, OF PEARSALL, TEXAS.
ACETYLENE-GAS GENERATOR.
SPECIFICATION forming part of Letters Patent No. 651,869, dated June 19, 1900.
Application filed January 25, 1900. Serial No. 2,782. (No model.)To all whom it may concern:
Be it known that I, CHARLIE M. LINDHOLM,
a citizen of the United States,residing at Pear-
sall, in the county of Frio and State of Texas,
5 have invented a new and useful Acetylene-
Gas Generator, of which the following is a
specification.
My invention relates to improvements in
acetylene-gas generators of that class in which
1o the generator is combined with the expansible
tank for operation automatically therewith;
and one object in view is to provide an im-
proved generator of this type which is kept
in a relatively-cool condition by a surround-
15 ing bath of water and which generator is re-
movable at will from the floatable bell of the
tank.
A further object is to. prevent the waste'
carbid from dropping into the water of the'
20 expansible tank and to provide for the free
discharge of gas from the generator to the
floatable bell, while at the same time permit-
ting the expeditious removal of said gener-.
ator for the purpose of cleaning and recharg-
25 ing the same.
With these ends in view the invention con-
sists in the novel combination and construc-
tion of parts, which will be hereinafter fully
described and claimed.
30 In the drawings, Figure 1 is a perspective
view of an acetylene-gas generator construct-
ed in accordance with my invention. Fig. 2
is a vertical sectional elevation on an en-
larged scale as compared with Fig. 1. Fig.
35 3 is a detail perspective view of the generator
proper removed from the expansible tank.
Fig. 4 is a vertical sectional view through the
generator assembled within the waste-recep-
tacle.
4o Like numerals denote corresponding parts
in each of the several figures of the drawings.
The expansible holder is similar to devices
ordinary in the art in that it consists of a tank
10 and a floatable gas-bell 11, which is in-
45 verted into the tank, so as to have its lower
open portion normally immersed in a water
seal contained in the tank. A cylinder 12 is
arranged centrally within the floatable bell,
and in the head of this bell is an opening 13,
5o around the edges of which the cylinder 12 is
secured firmly to the bell-head. This cylin-
der is open at both ends, so that the generatormay be easily inserted into its upper open
end, while the lower open end of the cylinder
is substantially flush with the corresponding 55
end of the bell, whereby said lower end of the
cylinder is sealed by immersion in the water-
bath contained in the carbid.
14 designates a waste-receptacle which is
used in connection with the generator proper 6o
for the reception of the waste or spent carbid
that may drop from the carbid vessel of said
generator. This waste-receptacle is closed
by an imperforate head at its lower end; but
its upper end is open and flanged, the diam- 65
eter of the flanged end of said receptacle be-
ing less than that of the opening 13 in the bell-
head. This construction enables the waste-
receptacle to be arranged within the cylinder
12 for its lower closed end to rest upon the 70
bottom of the tank,-and thus said receptacle
is arranged removably within the bell and
within the open - ended cylinder 12. At a
point intermediate of its length the waste-re-
ceptacle is provided with water-inlet open- 75
ings 15, and said receptacle is adapted to re-
main at rest on the travel of the bell and the
cylinder, so that the receptacle will be im-
mersed in the water of the tank sufficiently
for the openings 15 to lie below the water- 8o
level, thereby permitting the water to flow
into the receptacle in order to reach the ac-
tive material contained in the carbid vessel.
The generator proper has connected inner
and outer shells 16 17, arranged to form an 85
intermediate water - chamber 18, which is
adapted to contain a cooling-bath that sur-
rounds the inner generator-shell 16 for the
purpose of keeping the generator at a low
temperature. As shown more clearly by Fig. 90
4 of the drawings, the inner shell 16 is cylin-
drical, with an open lower end and a closed
upper end 19; but the outer generator-shell
18 is of conical form, so as to flare upwardly
and extend above the head of the inner shell, 95
the lower end of the flared outer shell being
joined in any suitable way to the correspond-
ing end of the cylindrical inner shell. * The
two shells,assembled and unitedas described,
provide a flaring chamber 18, which extends 1o0
above the head of the inner cylindrical shell,
so that the chamber may contain the cooling-
bath adapted to entirely surround the genera-
tor inner shell 16, except at the lower end
