APPARATUS FOR GENERATING CARBON DlOXlDE.

SPECIFIQATION forming part of Letters Patent No. 317,823, dated May 12, 1885.

Application filed December 29, 1884. (No model.) Patented in England March 22,1883, No.1,504.

To all whom it may concern.-

Beit known that I, JAMES MoEwEN, a subject ofthe Queen of Great Britain, residing in the city of Manchester, England, haveinvented newjand useful Improvements in Generators for Generating Carbonic-Acid Gas or other Gases, (for which I have obtained a Patent in Great Britain, No. 1,504, dated March 22,1883,) of which the following is a specification.

This invention relates to certain improve ments in apparatus for generating carbonicacid and other gas, and the purpose thereof is to provide means for filling, emptying, and washing out the generator without loss of gas and without admitting atmospheric air; to provide means for automatically supplying the generator with acid upon a diminution in the flow of gas, and to combine with the reservoir an automatic call,whereby the attendant may be summoned when the reservoir becomes exhausted, or nearly so.

The invention consists in the several novel features of construction and combinations of parts hereinafter fully set forth, and then pointed out in the claims.

Referring to the drawings, Figure 1 is a central vertical section. Fig. 2 is aside elevation. Fig.3 is a detail elevation partly in section. Fig. 4 is adetail section of the lower portion of Fig. 3. Fig. 5 is a horizontal section of the lower vessel detached.

In the said drawings, the reference'letter A indicates the generator, having an agitator, B, which is mounted upon a shaft, 0. This shaft has bearing in trunnions D, which receive screw-caps D, containing packing to make a gas-tight joint. A fast and loose pulley, E E, are mounted upon one end of said shaft to receive belting from any convenient power.

Opening from the bottom of the generator A is a pipe, F, which communicates with the inlet-pipe G and the siphon-pipe J. These three pipes all open into avalve-chamber, F, within which is arranged a three-Way cock, F The inlet-pipe G is curved upward, and upon its end is mounted a charging-vessel, H, for receiving the whiting or other material used in generating the acid. The siphon-pipe J is provided with a swivel-joint, I, by which the end of the pipe may be turned into the positions shown in Figs. 3 and 4.. The generator is made of lead or other suitable material, and in two parts. For convenience in inserting the agitator,I prefer to divide-the rounds said vessel at the meeting edges of the upper and lower halves. These flanges are united by bolts, and the trunnions are bound together by nuts S. A gland is formed upon each cap D,which closely fits the cap and enters the trunnion, as shown in Fig. 1. Above the generator, in any suitable position, is placed the gas-holder. It consists of a lower vessel, L, adapted to contain water, and a reg ulator, K, which rises and falls therein, being guided and retained in true vertical position by a standard, P, rising from the center of the vessel L and received by a central tube, 0, connected with the bottom of the regulator K. A vertical pipe, M, rises from the top of the generator A and passes up through the vessel L as high as its top. A draw-off, N, is carried from the same height down through the bottom of L, and connected with the ordinary pumps.

When it is necessary to empty the generator A of its contents, the cock F is turned, as shown in Fig. 3, whereby the inlet-pipe G is closed and the siphon J opened to the generator. The siphon is then turned up until its open end is brought about on a level with the bottom of the vessel. The generator may now be opened, and the pipe will, when the operation is completed, remain .full of liquid, which prevents the inflow of air. If it becomes necessary to discharge thewhiting or other substance from the vessel H and inlet G without carrying it into the generator, the cock F is turned to the position shown in Fig. 4, and the siphon-pipe J is turned down, when the whole contents of H may be emptied into any suitable vessel, thereby economizing material and time and facilitating the operation of washing out the passages. WVhen it is necessary to replenish the generator with material from the charging-vessel H, the cock F is turned, as shown in Fig. 1.

Upon one side of the vessel L, at any con venient point, is placed a glass vessel, T, having a pipe, 6, opening from its bottom and entering the generator.

Into the upper end of said vessel T is inserted a pipe, 1, connected above with an acid-reservoir. To the lower end of said pipe is attached a valve-chamber, 1, closed at its lower end by a diaphragm, in which is seated a valve, 2. The lower end of this valve has a cross-bar, 3, to which are connected rods 4, connected above to a bar, 5, which is mounted upon one end of a lever, 5, said lever being fulcruined upon a support which is adjustable upon the acid-pipe 1, and having its free end projecting over the top of the regulator K. When the latter descends, the lever drops, raising the rods 4 4 and opening the valve 2, whereby acid at once flows into the generator. This produces an immediate liberation of gas, which raises the regulator, lifts the lever, and cuts off the flow of acid. The acid-pipe 6 is carried down and then up before entering the generator, inorder that a sufficient body of acid may alwaysremain therein to balance the pressure in the regulator K. The valve 2 is a double valve seating upon both sides of the diaphragm. Thus, when the regulator dropsa sufficient distance, the lever 55 will close the valve and cut off the flow of acid. Thereby,when the whiting in the generator is spent, the regulator will sink so far as to effect this operation and prevent a waste of acid.

To call the attention of the operator to this condition, I attach to the regulator K a finger or spring, 7, which rises and falls with it. If the regulator falls this finger strikes the spring 8, which is connected to the vessel L, and is in connection with any suitable call, by means of the rod 9 or other devices. An electric call may be used in this position with advantage.

WVhat I claim is- 1. In an apparatus for generating carbonicacid or other gas, the combination,with agenerator, of a charging-vessel, an inlet-pipe, a

siphon-pipe, and a central bottom outlet having a valve-chamber with which both the inlet and siphon communicate, and a three-way cock placed in said valve-chamber, substantially as described.

.2. In an apparatus for generating carbonicacid gas, the combination,with a generator, of a gas-reservoir containing a regulator which rises and falls as the gas accumulates or is removed, an acid-supply pipe entering the generator, and a valve closing said pipe and connected with a lever which is fulcrumed with its free end above the regulator, substantially as described.

3. In an apparatus for generating carbonicacid or other gas, the combination,with a generator, of a reservoir having a rising and falling regulator, an acid-supply pipe entering the generator, a valve closing said pipe and connected by rods with the lever, having its free end over the regulator, a spring mounted upon a suitable support near said regulator and connected with a call-bell, and a finger upon the latter,-which is brought into contact with the spring as the regulator falls, substantially as described.

4. In an apparatus for generating carbonicacid or other gas, the combination,with a rising and falling regulator, of a valve closing an acid-supply pipe, rods operated by a lever to actuate said valve, and a vertically-adjustable support upon which said lever is fulcrumed, substantially as described.

In witness whereof I, the said JAMES Mc- EWEN, have hereunto set my hand and seal this 1st day of December, A. D. 1884..

JAMES MOEWEN.
