Improvements in Acetylene Gas Apparatus.
We, JOSEPH NEWBURGHI GOLDBACHER, of 113. East 85th Street, in the City of
New York, in the County of New York and State of New York, United States
of America, Lawyer, and EUGENE BOURNONVILLE, of 32. Beacon Street, in Jersey
City; in the County of Hudson and State of New Jersey, United States of
America, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained, in and by the following statement:-
The invention relates to improvements in apparatus for producing acetylene
gas, and consists in the novel features and combinations hereinafter described
aud particularly pointed out in the claims. Our invention is presented in this
application in an apparatus comprising a generator tank containing water, a
gasometer receiving the gas from said tank, means operable from the gasometer
for feeding charges of the carbide to the said tank, and an outlet pipe for gas
from the gasometer; and the purpose of our invention is to improve such
apparatus as a whole, and also in its details. Our invention pertains more
particularly to novel automatic means for feeding the charges of carbide to the
generator tank, to means intermediate the gasometer and the feed wheel, whereby
The latter, at the proper time and to the proper extent, is actuated by the move-
ment of the gasometer, to novel features hereinafter described pertaining to the
generator tank and means for controlling and delivering the gas from the
generator tank to the gasometer, and to novel features whereby the attendant
may withdraw the water and deposits from the generator tank without interfering
with the continued use of the apparatus. The invention will be fully understood
from the detailed description hereinafter presented, reference being had to the
accompanying drawings, in which:-
Fig. 1 is a side elevation of an apparatus constructed in accordance with and
embodying the invention.
Fig. 1 is a detached vertical section of a seal box or safety governor connected
with the outlet pipe for gas from the gasometer:
Fig. 2 is a central vertical longitudinal section of same:
Fig. 2 is a detached top view of a horizontal partition (b) forming a part of
the apparatus;
Fig. 3 is a top view, partly in section and partly broken away, of same, this fig.
indicating by the dotted line 2-2 the section on which Fig. 2 is taken;
Fig. 4 is an enlarged detached top view of a water seal or trap through which
the generated gas must pass on its way from the generator to the gasometer; and
Fig. 5 is a vertical transverse section of same on the dotted line 5-5 of Fig. 4.
In the drawings A designates the exterior shell or casing of the apparatus,
which casing is in substantially two sections, lettered B, C, respectively, and con-
nected together on the line D (see Fig. 2), whereby the water within which the gas
is generated is enabled to occupy substantially the whole of the section B and a
Dortion of the section (

page_text: The casing A constitutes a generator tank into which the water is poured
through the funnel E and pipe F, and a portion of which tank is partitioned off
by the plates G and H to form an auxiliary tank I to receive the gasometer J and
the water, lettered K, which is entirely separated from the water in the main
tank and is employed as a seal for the gasometer J. The gasometer J is of
customary form, construction and operation and is adapted to have a vertical
reciprocating movement within the auxiliary tank I. The water K employed for
scaling the gasometer J is never in communication with the water in the main
tank A, and is supplied to the tank I by being poured into the upper end of
the latter.
The bottom of the section C is substantially flat, and the lower end of the
section B is in the form of an inverted cone, and the outlet therefrom is con-
trolled by a valve L, which, when opened, will permit of the escape of the water
from the tank A and all sediment and waste products which may have accumu
lated within the said tank A. Upon the flat bottom of the section C is provided
the scraper blade M to which is connected a wheel or handle N, and which, by
means of the said handle or wheel N, may be given a revoluble motion over the
said bottom for the purpose of loosening the waste products therefrom and
causing them to pass into the cone-shaped outlet portion of the section B.
Within the auxiliary tank I is provided the vertical cylinder P' which extends
upward from the partition H to within a short distance below the upper edges
of the section C and is provided upon its upper end with a layer of filtering media Q
confined between perforated or porous plates, cloths or housings R, R. The
cylinder is less in diameter than the diameter of the gasometer J, and said
gasometer passes downward over said cylinder, as illustrated in Fig. 2. The
upper end of the cylinder P will always be above the water level in the auxiliary
tank I. The partition H below the cylinder P is open, as at S, and through this
opening, in the manner hereinafter described, the generated gas passes upward
to within the cylinder P and thence passes through the filtering media Q and into
the gasometer J.
The calcium carbide is fed to the section B of the casing A, through the
chute T, which is located adjacent to the upper portion of said section B, and
has its delivery end considerably below the water level in said casing A. The
chute T communicates with the interior of the section B, and hence becomes
substantially filled with the water, and said chute at its lower end which projects
into the section B comprises the opposite sides W and downwardly and inwardly
inclined bottom V, upon which the calcium carbide will fall, and which will
direct said carbide inward to a proper extent within the section B. The sides W
of the lower end of the chute T are led high enough to prevent the passage of
any gas into the chute T and are not connected within the section B except by
the aforesaid inclined bottom V and by an outwardly and downwardly inclined
plate X, whose purpose is to deflect inward any ascending gas which, in the
absence of said plate, might be inclined to pass out through the chute. Such
portion of gas as may pass into the lower end of the chute T below and outward
beyond the lower edge of the plate W, will pass upward through the open
space a left between the outer vertical wall of the section B and the upper
edge of the plate W.
Within the upper portion of the section B and at the height desired for the
water level therein, is provided the horizontal partition b, whose edge adjacent to
the chute T is turned downward to form the deflector c, which inclines downward
and outward toward the chute T and passes between said chute and the upper
portions of an upwardly and inwardly extending deflector plate d, as shown in
Fig. 2, whereby the water seal e is formed through which the generated gas must
pass on its way to the upper end of the section B. In addition to the formation
of the water seal e by the deflecting plates c, d, the plate d in connection with
the adjacent side wall of the section B, forms a receptacle which will hold water
sufficient to at all times maintain the water seal, and particularly during such

page_text: periods as the water may be withdrawn from the casing A. The generated gas
passes to the upper side of the horizontal partition 6, and hence when the water
for any reason is withdrawn from the casing A, the quantity of water held by
the deflecting plate d, will be sufficient to prevent the downward passage of the
5 gas from the upper to the lower side of, the partition b, and thus the water may
be withdrawn from the casing and the latter cleansed without danger of the
escape of the gas with the water, and without interfering with the continued
use of the gas within the gasometer J.
The
The lower edges of the deflecting plate care preferably serrated to the more

upper end of the section B, and thereby prevent flickering at the burners.
horizontal partition is wrapped close around and above the inner protruding
end of the valve f, which is on the line of the water level within the section B,
and which when opened, during the filling of the generator tank with water,
will permit the escape of all of the air from below the partition b, and thus the
formation of an air cushion below said partition is prevented. The air vent
valve fis clearly illustrated in Fig. 1, and during the filling of the generator
tank with water, this outlet valve will be opened and the water poured into the
generator tank through the funnel E and pipe F. When the water is escaping
through the valve f, it will be an indication to the operator that the water has
reached its proper level within the generator tank, and thereupon he will close
the valve f and cease to pour water into the funnel E. The horizontal partition b
is provided with the downwardly extending pipe g, whose lower end is curved
upward, and the purpose of this pipe is to permit a circulation of the water from.
the upper to the lower side of the horizontal partition 6, when due to excess of
pressure or other cause such circulation is desired. The upwardly turned lower
end of the pipe y forms a water seal and will hold sufficient water to prevent,
under usual conditions, the downward escape of the gas through said pipe g when
the main body of water is being withdrawn from the casing A during the
cleansing of the latter.
Upon the section B of the main casing A is secured the dome h within which
the generated gas passes, and from which said gas finds its outlet through the
pipe i, which extends downward from within the dome to the trap which is
secured to the lower side of the partition H, and at its upper end is entirely open
and in line with the opening S at the base of the cylinder P. The construction
of the trap is more clearly illustrated in Figs. 2, 4 and 5, in which it will be
seen that said trap is in the general form of an oblong receptacle containing a
definite supply of water and having secured therein the elongated frame k which
forms a gas chamber into which the pipe i directly leads, and which chamber
is sealed around its lower edges with the water within said trap j, as shown in
Figs. 2 and 5. The frame is of metal and secured to the trap j, and the sides
of this frame are serrated, as shown in Fig. 2, in order that the gas which
passes into the chamber formed by the frame k may, when escaping around the
lower edges of the said frame, be diffused by its contact with the serrations at
the lower edges of the said sides. The gas which passes from the pipe i into
the chamber formed by the frame will pass below the serrated edges of the sides
of said frame k, and then ascend through the water held by the trap j, and thence
pass upward through the opening S into the cylinder P, whence it will pass.
through the filtering media Q and into the gasometer J. The trap is pro-
vided with the pipe m having the valve n, plug o and seal p, the latter being
formed by giving the pipe the downwardly extending U-form, shown in Fig. 2.
When the plug o is removed from the pipe m, the water for the trap may be
poured into the pipe o and be by it directed to the trap j. When it is desired
to empty the water from the trap j, this will be accomplished by opening the
valve n and tilting the apparatus in a proper direction. By opening the valve n
at any time, any surplus of water arising from condensation or other cause within
the trap will escape and the proper water level within said trap be reached.

page_text: The gas passes from the gasometer J through the pipe g, as shown in Fig. 2,
to the nozzle r, shown in Fig. 1, to which nozzle the customary pipe or tube
leading to the burners may be applied in a well known manner. The pipe g at
a point exterior to the casing A is connected with the safety seal valve box or
governor F, as shown in Fig. 1, and Fig. 1.
The calcium carbide may be fed to the chute T in any suitable manner, but a
part of the present invention pertains to the means illustrated in the drawings
for effecting an automatic feeding of the carbide to the chute T in proper regulated
quantities and through the instrumentality of mechanism connected with and
influenced by the movement of the gasometer J. In accordance with this portion
of my invention an enclosing frames is applied to the upper end of the chute T,
and within this frames is mounted, upon the horizontal shaft t, the feed wheel w,
which is directly below the downwardly and outwardly inclined wall of the
hopper A, into which the calcium carbide in bulk will be placed. The inner
wall B of the frames conforms to the circular outline of the feed wheel wo and
connects with the downwardly and outwardly inclined wall of the hopper A¹
at a point above and slightly to one side of the vertical center of the wheel w and
thus the calcium carbide descending from the hopper A' is directed to the upper
side of the wheel w, as shown in Fig. 2; and is prevented from passing between
the aforesaid wall B and the adjacent surfaces of the said wheel. The frame s
extends above the wheel, and its upper end C connects with the outer vertical
side of the hopper A at a point directly above the wheel w, whereby there is
formed an opening, from the hopper A' to the wheel w, which is substantially
vertical and tends to direct the calcium carbide on a line toward the outer side
of the wheel w. The throat or opening from the hopper A' into the chamber
formed by the frames is controlled by the weighted hinged gate D¹, which has
a normal tendency to close said throat or opening and is only opened by the
action, against said carbide, of the wheel a during the rotation of the latter.
The action of the weighted gate D is to prevent any surplus quantity of calcium
carbide from being fed to the chute T and to restrain the carbide upon the
wheel, and permit the same to be fed to the machine by said wheel only in the
limited quantities desired for the generation of the requisite amount of gas:
The upper end of the hopper A' is in the form of a hinged door, and hence said
hopper may be opened to receive the calcium carbide in bulk, and then closed.
The upper end C of the frames is likewise in the form of a hinged door which
may be opened and closed at will, and hence the action of the feed wheel w and
gate may be inspected at will. Upon the outer side of the frames is also
provided for convenience of inspection and of removal of the feed wheel a hinged
door E. Upon the outer side of the section B of the casing A, and adjacent to the
lower portions of the feed chute T, is provided the vertically clongated glass
panel G, through which the contents of the generator tank may be inspected, and
through which also the ebullition created by the conversion of the calcium
carbide into the gas may be observed. The glass panel G¹ enables the attendant
to observe the condition and action of the water within the main casing A, and
thus serves as an accurate means for indicating whether the generator tank is
in proper operative condition, and when it is necessary or desirable to withdraw
the sediment and water from said tank and clean the laiter.
:
The wheel wo is formed with the longitudinal projections having the tangential
faces H and I¹ of the character illustrated, and it has been found that when the
wheel w is formed with the corresponding longitudinal projections of the
character shown, the wheel will not only not become clogged but may be relied upon
to feed substantially uniform quantities of the calcium carbide to the feed
chute T. While the present invention is not limited in every instance to the
special form of the wheel wc, shown in Fig. 2, a part of the invention is so limited
and this part of the invention is deemed to be of special importance in that
thereby great reliability in the feeding of the proper quantities of the calcium
carbide is assured.

page_text: We also provide means for preventing any particles of the calcium carbide from
entering between the ends of the feed wheel w and the sides of the enclosing
frame s, and these means are more particularly illustrated in Fig. 2, and consist
of a disk w¹ secured to each end of the wheel and being of greater diameter
than said wheel c, and of the check pieces to which project downward from the
inner walls of the upper contracted end of the frames and have curved lower
edges. The upper contracted end of the frames has the opposite walls s¹, which
set inward from the main side walls of the frames, atd thus below said walls s¹
are formed offsets within which the disks on the ends of the feed wheel are
housed and rotate. The cheek pieces w being set inward by reason of the
inwardly contracted walls s', prevent any particles of the calcium carbide from
getting between the disks and the adjacent walls of the frames.
ever,
A further portion of the invention relates to the means intermediate the feed
wheel and the gasometer J, whereby the latter may be relied upon to actuate,
at the proper time and to the proper extent, the wheel w to feed the calcium
carbide to the generator tank; and this portion of the invention is not limited to
the special feed wheel w, but comprises any feed wheel adapted to be operated by
the means constituting this portion of the invention and located intermediate the
feed wheel and the gasometer. The mechanism constituting this portion of
the invention is illustrated in Figs. 1, 2 and 3, and comprises a chain or flexible
connection J positively secured at one end to the gasometer J, and thence extend-
ing upward over the pulleys K¹, L¹, and thence downward to the outer end of
the lever M, which is swiveled upon the end of the shaft t carrying the feed
wheel w. The lever M is provided with the spring pawl N', which is in engage-
ment with the ratchet wheel 01 secured upon the shaft t. The lever M' is heavier
at its outer end to which the chain J₁ is secured, and hence will descend at that
end of its own weight until arrested by the rigid stop 11, which defines the limit
of the downward movement the end of the lever M shall have. When the end
of the lever M is descending of its own weight to the stop P", the pawl N will
simply slide over the teeth of the ratchet wheel O without rotating the latter,
and consequently without rotating the shaft and feed wheel w. When, how-
the outer end of the lever M is elevated under the action of the chain J',
the pawl N will engage the teeth of the ratchet wheel 01 and cause the latter
to have a definite revolving motion in one direction; and at such time this
revolving motion of the ratchet wheel 01 will be communicated through the
shaft t to the feed wheel w, and thus the feed wheel will be caused at such
period to feed a limited quantity of the calcium carbide to the feed chute T.
The chain J has a fixed connection at one end with the gasometer J, and at the
other end with the outer portion of the lever M¹, and that portion of the chain J¹
intermediate the pulley wheel L' and the lever M¹ is preferably provided with
the weight Q, which will preserve the chain in a taut condition over the
pulleys K, L. It is to be observed, however, that the chain J is of such length
that it is not taut throughout its entire length except at the definite period when
the gasometer J is reaching and at on leaving its lower position, and it becomes
necessary to elevate the outer end of the lever M¹ for the purpose of causing the
pawl N to rotate the ratchet wheel 0¹ and feed wheel w. In the condition of the
apparatus illustrated in Figs. 1 and 2, it may be assumed that the gasometer .J
is either ascending or descending. If it is assumed that the gasometer J, shown
in Figs. 1 and 2, is ascending, it will be observed that in the natural operation
of the weight Q₁ the chain J will be, by said weight, drawn over the pulley
wheels K and L, and will hang downward in a slackened condition adjacent to
the outer end of the lever M. On the other hand if it be assumed that the
gasometer J, due to the consumption of the gas, is descending, it will be apparent
that the weight of the gasometer J will draw on the chain J¹, and finally, when
nearly to its lowest position, will, by moving all of the slack from said chain
draw the latter to a taut condition from the gasometer to the lever M', and there-
upon, during the final descending movement of the gasometer J, the motion of

page_text: the latter, by continuing to pull on the chain J, will effect a limited upward
movement of the outer end of the lever M for the purpose thereby of effecting
a limited revoluble motion of the ratchet wheel and the feed wheel 16, the
latter being thus caused to feed a proper quantity of the calcium carbide to the
chute T. Thus it will be understood that the chain is never taut except
during the final portion of the descending motion of the gasometer J, and
possibly during the first upward portion of the motion of the gasometer J, the
chain being then held taut by the. weight of the lever M until the latter has
descended to and become arrested by the stop 1". It is one of the purposes of
this portion of the invention to prevent the gasometer, through the chain J',
from acting on the feed wheel at any time other than during the final portion
of the downward motion of the gasometer J, and to provide such actuating means
intermediate the gasometer and the feed wheel that the latter may remain'
entirely idle except during the latter portion of the descending motion of the
gasometer, and then be actuated by a reasonably quick motion and only during a
limited portion of the movement of the gasometer.
The operation of the apparatus herein before described, has been substantially
pointed out in connection with the description of the construction of the apparatus.
The calcium carbide in bulk will be placed within the hopper A¹, and the water
will be supplied to the generator tank, the trap j, the blow-off valve or governor F¹
and the auxiliary tank I. The water supplied to the auxiliary tank I is simply
for the purpose of sealing the gasometer J; and the water supplied to the main
casing exterior to the tank I is for the purpose of converting the calcium carbide
into the gas, and this water, as herein before described, will fill the generator tank
up to the level of the horizontal partition b. In first starting the apparatus into
actual operation, a portion of the carbide will be manually fed to the chute T, but
thereafter the feeding of the carbide to the chute T will be accomplished auto-
matically by the movement of the gasometer J. The gas generated within the
tank formed by the casing A will ascend to the chamber above the horizontal
partition and enter the dome h, whence it will descend through the pipe i into
the chamber formed by the frame k, and thence descend around the lower edges
of the sides of said frame, and after passing through the water contained in the
trap, will pass upward through the opening S and into the vertical cylinder P,
from which the gas will pass directly through the filtering media Q and into the
gasometer J, whence it will be fed to the burners by means of the pipe q. The
automatic feeding of the carbide to the feed chute T is accomplished from the
gasometer by means of the chain J, lever M, pawl N1, ratchet wheel O', shaft t
and feed wheel c, and, as above described, in the operation of this part of the
apparatus, the feed wheel is maintained entirely idle except during the latter
portion of the downward motion of the gasometer, at which time the gasometer
having then drawn the chain J taut, will on its final movement downward
elevate the weighted end of the lever M, and through the intermediate mechanism
above described, effect a limited motion of the wheel w, and thereby cause
said wheel to carry a limited quantity of the calcium carbide to a position in
which it will be left unsupported and be allowed to fall directly into the chute T,
and be by said chute directed into the water contained within the generator tank.
The carbide is directed to the wheel w through the substantially vertical throat
and from a hopper having an inclined base, and thereby the bulk of the carbide
is largely supported within the hopper and is prevented from having a tendency
to leave the hopper with undue speed. That portion of the body of the carbide
which is allowed to pass through the throat leading from the hopper A', is sup-
ported upon the wheel w and is retarded in its outward movement by the weighted
gate D, which is automatic in its operation and simply presses against and upon
the carbide leaving the hopper A¹ and prevents the carbide from moving with
undue freedom over the wheel w.

5 escape.
The withdrawal of the lime and other pro-
ducts as well as the water from the generator tank, will be readily accomplished
by opening the valve L and permitting the entire contents of the generator
tank, with the exception of a small quantity of water held by the plate d, to
That portion of the water held by the plated becomes of importance
especially when the valve L is opened, since it will effectually seal the gas within
the upper end of the section B of the casing A, and thereby prevent the escape
of the gas with the water. The employment of the trap jis of advantage in that
thereby the gas passing into the cylinder P becomes more thoroughly diffused,
and said trap prevents the return of the gas from the gasometer J and cylinder l'
into the generator tank under any conditions in which it might be desired to
open the valve L and cleanse the generator tank. The general form and con-
struction of the exterior casing subdivided by the partitions G, H, into the
generator tank and auxiliary tank, the latter to receive the gasometer, is of
advantage, since thereby a very compact structure having the maximum capacity
for the generation of gas is produced.
