IMPROVEIVIENl IN CARBONIO-ACID-GAS GENERATORS- Specification forming part of Letters Patent No. 150,995, dated May 19, 1874; reissue No. 5,983, dated July 21,1874; application tiled June 23, 1874.

To yall whom it may concern:

Be it known that I, OTTo ZwrETUscH, of Milwaukee, in the county of Milwaukee, in the State of Wisconsin, have invented certain Improvements in Oarbonic-Acid-Gas Generators, of which the following is a specification:

My invention has for its object the generating of carbonio-acid gas; and the machinery for accomplishing this object consists of a generator made of rubber, and is so arranged that it will stretch both ways-upward and downward. The gas is generated by muriatic acid and marble chips. As soon as the marble comes in contact with the acid, gas is liberated, and the pressure of the same will stretch the rubber, and the marble will be lifted out of the acid, or the acid will be allowed to sink below the marble, and the gas will cease to be generated; but as soon as the gas is decreased and the pressure reduced the marble will again come in contact with the acid, and the gas will be again generated, and thus the generator acts automatically.

Figure 1 is a sectional view of my invention. Fig. 2 is a view of a section of rubber of which I sometimes form the cover of my generator. Fig. 3 is also a section of rubber which I sometimes use as a cover for the generator; and Fig. 4 is a sectional view of the generator as made without the lever and weight, as shown in Fig. l.

A is the generating-chamber; B, the rubber cover ot' the generator; O, the generator, made of rubber; l), marble-basket; E, supply-pipe connected to the basket; F, cap secured to the top of the supply-pipe; IE G, outlet for the gas from the generator and supplypipe for the gas to a washer H, inlet-pipe to the generating-chamber; I, outlet-pipe at the bottom of the generator; K K, anges of metal, which secure the cover B and generator O together; L, weight on the end of lever O, m, fulcrum of lever O; n., guide for lever O, and which steadies it; O, lever, which,

with the weight L, gives pressure to the gas,

or, by blocking it in guide n, it makes the basket D and cover B stationary.

This generator is operated as follows: Fill in, through inlet H, acid suticient for the purpose, and ll into basket D, through supplypipe E, chips of marble, when the weight ot the marble will sink the basket into the acid, and gas will bey generated, the space above the acid will be filled, and the pressure of the gas will stretch the generator O and cover B, so that the basket will be lifted outof the acid, the basket being secured to the cover B, so

that it will be lifted as the cover is lifted; or

if the basket be rendered stationary by any means, then the generator will be forced downward, and the acid will be allowed .to sink below the marble, and gas will cease to be generated.

The upward extension of the top of the generator may be controlled by placing the lever in position and inserting a pin above it. It is evident that the top with the basket could pass no higher than the pin would allow, and

any further extension of the gasometer by the pressure of the gas would necessarily be downward.

The Figs. 2 and 3 are merely to show different-formed covers that may be used.

The basket D is made of rubber, and attached and hung to cover B.

I claim as my invention- 1. Lever O and weight L, in combination with generator O, cover B, and pipe E, substantially as described.

2. -A carbonic-acid-gas generator constructed with cover B, generator O, audbasket D, substantially as specified.

3. Basket D, attached to and hung to cover B, substantially as specified.

OTTO ZWIETUSCH.
