"Acetylene Gas Generators."
I, DAVID LOUIS BAUMGARTEN, Pikes Bldg, E, 4th St., Cincinnati, County of
Hamilton, State of Ohio, 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 ascertained in and by the following statement:-
This invention relates to improvements in generators used in the manufacture of
acetylene gas. This gas as is well known, is manufactured by subjecting carbide of
calcium to the action of water, the process of combining the two resulting in the
production of the gas which is set free, leaving the unused and decomposed parts of
the carbide in form of a muddy residue.
In my generator, the carbide is supplied to a substantially permanent body of
water and one feature of my invention consists of constructions whereby such supply
proceeds from time to time and automatically in proportion to the consumption of
Other-features-are-a-construction whereby the resulting residue may-be--drawn
off-at-times-as--rendered-necessary--without--interfering--with,--or-interrupting the
gas.

The generator consists substantially of a sheet metal tank 8, preferably galvanized,
having a funnel shaped bottom, the lower end of which connects by a neck 9, to a
box 11, which receives the carbide, and in which the generation proceeds. Tank 8,
bas double walls with a space between them, which is filled with water, and receives
the wall of another inverted tank 12. Box 11, and tank 8, are charged with water
to a height about as shown in the drawing, the carbide being introduced to the water
through a chute 13. The generation of gas ensues as soon as the two come together,
but proceeds principally in box 11, the nascent gas rising above the water, and
occupying the space in the upper part of tank 8 and 12, the latter constituting a
gasholder which slowly rises as the gas accumulates. These parts of the apparatus,
as well as a suitable outlet pipe 10, which supplies gas to the service pipes are of the
usual customary construction and arrangement. The-upper-end-of-chute-13,-enlarges
to-form-a-hopper-14;-and-has-superposed-upon-it-a-rectangular-box-15.--Within-this
Intter-near-the-top-and-bottom, and in free-running bearings, are mounted guide
rollers-10,-between-and-around-which-a belt-17, is-stretched-carrying a-number-of
buckets-18. The construction-and-arrangement above-described, is illustrated-and
shown-in-Figures-7,-9,-9-and-10.
These buckets-on-one-side,-as-shown on the left-in Fig. 7;-are, charged preferably
all--at-once; necess-being-had--through-a-door-10. Each bucket-should-contain

which tendeney however, is-also-normally-restrained by a locking mechanism-until
such-time-when-the-gasholder requires the action-of-the-generator-for-replenishing-it
with gas and for which purpose the latter must be supplied with carbide. This
locking mechanism consists of a notched locking wheel 21, rigidly-mounted upon
the spindle of one of the guide rollers 16, preferably-the-lower-one-and-outside-of
box 15, the particular spindle being sufficiently extended-for-such purpose. It is
normally-locked against rotation-by-a-detont-22,-occupying one of its notches, and

to prevent the escape of gas may be provided. It-also prevents the-riding-of-moisture
of-the-earbide-supply-above. This valve tilts under the weight of the carbide which
proceeds downwardly while the former closes again by aid of a spring or weight
as shown. The carbide slides down the inclined bottom of tank 8 and enters box 11.
The generation takes place in box 11, but gas is set free as soon as the carbide enters
the water so that a re-action upon the gas holder takes place at once under which
tank 12 is lifted. to-immediately release-detent-22-as-explained-before. To-permit

guide rollers 25, which move on upright rods 26, the latter being connected to form
a frame which supports the whole apparatus.
To prevent as much as possible the rising gas from entering chute 13, a deflector 27
is provided at the lower end of the latter, which projects into the lower part.
of tank 8, and crowds the gas towards the center. The residue remaining after
this decomposition of the carbide, accumulates in box 11, in form of a sediment
of mushy consistency, which from time to time must be removed. It is desirable
that such removal be accomplished without interrupting the action of the gas holder,
that is, without reducing the contained pressure. It should also be accomplished
without loss of any of the water therein, because I have found that water which has
been used for sometime and becomes saturated with gas and soluble portions of
the carbide is preferable and quicker in action than if an entirely fresh supply of
water had been entered. For such purpose, I provide in neck 9, a cut off valve 28 of any
suitable construction which when closed permits the contents of box 11 to be readily
drawn off through a valved discharge pipe 29 without interfering in any way with the
gas holder above. Where possible, pipe 29 may waste into a sewer, but where the
absence of a permanent location makes such connection impossible, box 11 may
be readily removed to be emptied. In order to facilitate the thorough cleaning
and flushing out of the carbide containing box 11, and wash out the sediment,
provide a pipe 60 with a funnel-shaped opening and having a valve; this pipe
entering the neck 9 at a convenient point above box 11 and below valve 28. The
box 11 may be refilled with water through pipe 60, so that when valve 28 is again
opened, and the valve in pipe 60 is closed subtantially the same quantity of water
will be contained. To permit such, neck 9, is in two parts normally connected by
means of a serew-coupling 31, which when loosened permits the required temporary
disconnections. Since the escape of some water cannot be avoided, it is desirable
that means as shown at 32, are provided to receive it. A suitable form of valve is
a sliding gate valve as shown; operated by a lever 33, in Fig. 8, valve 28 is entirely
closed, and box 11 may be emptied. In Fig. 7, it is in an intermediate position
while being moved either for opening or closing. It is entirely opened and remains
so, to admit the carbide, as soon as box 11, is in position and with its discharge pipe
closed. The limited loss of water which the supplying of box 11 entails, is made up
through an opening 34 provided with a permanent funnel 35, and kept closed by a
lid 36. Instead-of-the-belt-17, a-chain-may-be-substituted,-in-which-ease-pulleys 16

Some ef-which-modified-constructions; constructions of the feed device I shall
describe, having reference first, to the form shown in Fig. 1. A, is
the generator; A¹ is the gas holder which fits within the generator; the
whole of which, is supported by uprights or standards B, B. C, is the
chute which enters the generator at the proper point; this chute being sụp.
plied with the proper balance-valve. Clamped to the standards B, B, by bolts
are projections or supports D, D, preferably in the manner shown in Fig. 2.
Resting on the supports D, D, and preferably secured thereto, by bolts or
otherwise, is a flanged ring or collar E, which surrounds the generator; the up-
right portion or flange of the ring forming a track or runway. F, F', are bands
also preferably made of sheet metal, of different diameter, the one within the other.
These bands are held together by stays or webs a, placed at suitable intervals.
Secured to the band F, in any convenient manner, are small pins b, on which are
mounted wheels c, which run on the track E; a sufficient number of them being
nsed to support the bands F, F¹. The band F, is notched on its upper edge,
as clearly shown in Fig. 1. Supported on a pin extending out from the generator A,
is a collar d, which has integrally formed therewith, on opposite sides and extend-
ing at right angles to the axis of the same arms e, f, forming what may be termed a
bell-crank. The portion f, of the bell-crank has pivotally connected to it, a dog or
pawl g, the end of which rests in the notches of the band F¹. The other arm e, of
the bell-crank is preferably formed with a slot, in which a pin on the rod h takes
This rod h, is shown as riveted to a rod or bar ', though it might be made in one
piece and bent at a right angle. This bar ¹, is provided with a collar at its end,
which is fitted over an extension or arm k, which extends out from and is secured
to the gas holder; the bar ¹ being securely held on the extension k, by a thumb-
screw, or in any convenient way..
It will thus be seen, that as the gas holder rises, as the supply of gas therein
increases, that the extension on the holder, pushes the angle arın h, h, upward, and
lifts the end of e of the bell-crank, by reason of the pin on the arın h, sliding in the
slot, thus rocking the bell-crank, by which the dog or pawl g, is slid over the incline
surface of the next succeeding tooth, and drops into the next notch. Then, as the
gasholder falls, by reason of the diminishing supply of gas therein, the bell-crank is
rocked in the opposite direction, and the dog g, is pulled forward, and having entered
the next succeeding notch, revolves the bands F, F1, a distance corresponding to the
size of the teath. Secured on the adjacent sides of the bands F, F', are lugs m, n,
preferably made of a blank of sheet metal; the lug m, being slotted in its center, as
can clearly be seen in Fig. 3.
To be placed between these bands F, F, and on the racks m, n, I have devised
rectangular boxes G, which are of a size sufficient to hold the requisite quantity of
carbide, which is to be fed into the generator through the chute C.
These boxes or receptacles G, are made of any light but sufficiently strong
material, with handles G" and have their bottom G¹, hinged at one end. Fastened
on the opposite end of the box, is a springy strip 1, which extends slightly below the
bottom of the box, and has a small opening therein. Secured on the bottom, is a
pin o, which normally passes through the opening A, in the strip or catch 7, thus
holding the bottom shut. In order to more securely close the box, and hold the
bottom tightly in place, I provide a spring p, on the bottom (Fig. 4) which lies
between the bottom and the pin o, pressing against the pin, and securely holding the
bottom in place. On one side of the box, I provide an extension q, which fits into the slot
in the rack m while on the opposite side of the box is provided a hanger », which
catches over the rack n. It will thus be seen that the boxes can only be put in place in
one way, and thus no mistake can be made in hanging the box in the carriage F, F¹;
the importantance of which, will readily be understood from the following description
of the operation of the carriage of feed-mechanisın. Attached to the chute C, on the
side from which the boxes or receptacles are revolved, and brought over the chute, is
a tripping pins, which extends up far enough to come in contact with the spring
catch l, on the box G. It is of course, understood, that the catch l, is on the opposite

page_text: side of the box, from the bottom hinge, and is so placed in the carriage F, F, that
when the tripping pin s is in contact with the catch, the entire box is over the
chute C. As the carriage is revolved by reason of the action of the gas holder, which
operates the dog g, the tripping pin 8, will disengage the spring catch, and release the
pin o when, by reason of the weight of the contents in the box G, the bottom will
drop and empty the contents into the chute C; and so on, with each succeeding box,
until they have all been emptied; when they are again refilled and hung in the
carriage, to again be emptied in the same manner. In place of the operating
rods or arms, h, and extension k, shown in Fig. 1, a device similar to that shown in
Fig. 16 11 may be used, in which a cord or chain may be attached to the gas holder at
any proper point; which cord operates over pulleys mounted on a cross piece attached
to the standards B, B, and is attached to the long arm e, of the bell-crank, which by
reason of its weight, will drop down as the gasholder rises, thus rocking the bell-
crank, and slide the dog or pawl backward, to engage in the next notch; then, as the
gas holder descends, by reason of a weight or the diminishing supply of gas, the cord
or chain will rock the hell-crank in the opposite direction and the dog will revolve or
push the carriage.

In Figure 18, 13 still another method of operating the carriage is shown, in which
the arm or rod h¹¹¹, which is suitably attached to the gas holder, is formed with
teeth, as seen in Figure 10 14. Secured to a rod or axle, which axle is supported in
any convenient manner, are toothed wheels 40 and 41; the wheel 40 coming in
contact with the teeth on the rod 11, thus revolving the axle or shaft 42, which
in turn will revolve the wheel or toothed disk 41, which meshes with the notched
band F of the carriage, thus operating same. The rod, is only supplied with
teeth a certain distance from the top, so that it will not operate on the disks or
wheels 40 and thus operate the carriage, until the gas holder has reached a prede-
termined point in its descent, bringing a conveyor over the chute C. The pinion 40,
is provided with a pawl and ratchet at its center marked 45; this pawl and ratchet
is of the familiar form, the pawl being pivoted to the pinion near its center and the
ratchet to the revolving shaft 42, the pinion being mounted loosely on the shaft so
that as the pinion is turned one way, it will carry with it the shaft which revolves
the pinion 41 which in turn meshes with the teeth on the carrier and propels the
Bame. When the supply of gas thus generated causes the gas holder to rise and
with it the shaft h, the pinion 40 will revolve freely on its axis, leaving the
shaft 42 with the pinion 41 stationary, ready to be revolved again upon the down-
ward movement of the shaft h¹, and again propel forward the carriage as before.
Figures 21 16 and 22 17 are different. elevations of a modified form of pawl and
ratchet for operating the feed. In said figures 50, is the upper portion of the gas holder,
which is moved up or down by the increase or diminution of the supply of gas; 51, is
a horizontal lug or extension provided with a set-screw 52, and a vertical opening
through which passes the movable bar 53. This bar 53 is provided with teeth which.
mesh with a pinion 54 and revolves the same. On the same shaft with the
pinion 54 is a similar pinion 55. Beneath this pinion 55, sliding in horizontal
ways, is a sliding carriage 56; this carriage 56 is provided with teeth which mesh
with the teeth of the pinion 55, so that as the pinion 55 is revolved, the
carriage 56 is moved forward or back. Pivoted to one end of this carriage 56, is
a pawl 57. This pawl 57 engages with the teeth on the carrier or feed-conveyor F¹.
As the sliding carriage 56 with the pawl 57 are moved forward by the downward move-
ment of the shaft 53, the feed carriage is propelled forward. When the supply of
carbide thus admitted to the ger erator, has generated gas sufficient to raise the gas-
holder 0 and with it the shaft 53, the pinions 54 and 55 are revolved the other way
and the sliding carriage 56 and the pawl 57 are drawn back; the pawl 57 being pivoted
lifts and slides over the teeth on the conveyor F¹.
I have thus described several forms of feed-devices and it will of course readily
be understood, that the various engaging and operating mechanisms, with the
boxes or carriage as described, may be applied to either a straight-away or circular
feed.
I--have-shewn-a-weight-and-pulley-as-the-means-for-propelling-one-form-of-con
veyor,-of-course Any power, e.g. a weight & pulley may be used, which will supply
a constant force, always in condition to take effect when the movements of the
gas holder releases the a catch which holds the conveyor stationary, when the further
supply of feed is not required, and-in-this-form-1-do-not-limit-myself-to the-weight
and-pulley.
In Figures 28 18, 24 19 and 25 20 I have shown modified forms of trip action
operating the feed apparatus, an exhaust pipe adapted to carry off the surplus gas,
a condensation trap to take the moisture from the service and the exhaust pipes,
a hand hole in the auxiliary feed box to permit of the residuum being readily
removed and a plug or opening to such box for the purposes of feeding in water.
The trip action mechanism consists in the bearings A attached to the frame of
the generator. The spindle B having the weighted lever C keyed at one end and
at the other the crank D. Pivoted to this is the pawl El which bears on the teeth

page_text: of F¹.
An adjustable projection H is attached to the movable part of the
gas holder J, and the lever Cu receives the pin H" in the groove C, the lever
in turning operates the pawl E", and moves the feed apparatus by means of the teeth
of Fi H, is the spindle of the slide or cut-off valve 12, for the purpose of flushing
the box S when clogged with residue by simply closing the valve 12 and opening the
plug P and the hand hole R, or the service connection Rt. The exhaust pipe L,
extends above the level of the water, and the trap K, fitting over it is attached to the
top of the holder J, holes K¹, are bored in the pipe K, so that when the gas pressure
raises the holder Jul to a certain height, the holes will be above the water, and
allow the escape of the gas. The service pipe M, and the exhaust pipe L, are con-
nected by Tjoints to branches L2 and M², which enter a.condensing box N, to which
there is a syphon outlet O. The box N, is filled with water up to the level of the
outlet O..
The residuum box S, is provided with a hand-hole R, the cover of which is released
by the thumb screws R' R'. The tap R2 is fitted into the hand-hole R.
In the upper
part of the box S, is a plug P, to allow of the flushing of the box S, which is done by
closing the slide valve 12, opening the hand-hole R, and flushing the residue out of the
box S, while the machine is in full operation, and by having cut off the box S by the
slide valve 12, it may be refilled with water without disturbance. By means of this
band-hole the heavy particles of the carbide which cannot pass off through the outlet
are removed with ease. The feed-hopper T2 of the chute C is provided at its.
mouth with a trap T3, to allow the passage to the carbide and water only, and
between the trap and the water line in the feed-hopper is a ventilating pipe T,
which carries off any gas which may accumulate there. The condensation box or
trap N is for the purpose of keeping the service and exhaust pipes free from water, and
by means of the syphon outlet is automatic in its action.
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. The combination of an acetylene gas generator consisting substantially of a
vessel adapted to contain water, a gas holder which receives the gas, a feed-device
consisting of a series of separable buckets to contain the carbide and means
controlled by the movement of the gasometer which cause the feed device to
supply the generator by dumping the contents of its separable buckets one at a
time.
