.To all whom t may concern: v

lEle it .known that I, EDWARD Haar, a Citi- -zen of the United States, residing at Easton, inthe county oit Nortliai'npton and State of Peur sy'lvi nia, have invented certain new 'and Jeful lmprovements in Chemical Apolf which the following is a` full, 'l exact description. invention relates to chemical appaweighing, absorbing, washing, or wise treating gases by passing the rough and in intimate Contact with a liquid or solid, and `its chief object is to provide an improved apparatus for the purpose, of sim-ple character, which can y, be -readily manipulated and can be easily eleaned and charged. To this' and other ends the ention consists in the novel leafter described.- .rred form the invention oomie,'preferably of glass, having la wide ino, i to vpermit easy introduction of large solids, .as for example large glass beads or balls such as are used for the pnrpose-ef carrying a ilm of reagent, say sul- 'urie s0 as to expose a large area to the current of gas, or for the purpose of breaking up the current into tortuous streams. The gas is introduced through a tube mniiected to the loweiportion of the bottle, ar passes out through a tube connected wi" the upper portion, preferably the neelf. The two tubes are connected to -v the saine valve cock, so that both the inlet and the o tiet are closed simultaneously and opened simultaneously.

' @The embodiment thus briefly outlined is illustrated in thev accompanying drawings, in which the ligure shows the apparatus in i lvertical section. I Tlieve. bottle is designated A, and is provides with a neck B, preferably wide,

. so as to filling with solid bodies or' rather large size when desired. The outlet tube C e t from the neck of the bottle, .and the hollow stopper D has a lateral aperture whieh b y a slight turn er the stopper may carried out of orinto register with the orifice oli the outlet tube. The inlet tube opens into-the' lower par*U of the bottle. and both tubes entend inte con I, nection wi a valve or cock havinga plug G. The i. ter is `integral withl the 'tube H and has angular passage l extending S5 from the endet tube H into positionfor registry wit".

the tube F; and the tapered.

shell J, in which the plug Gr turns, is ntegral with tube l. rlllie plug G also has an angular passage L extending from the tube K to a' point where 'it will register with tube C when passage l is in registrv with tube F. The te be treated is de ivered to the tube H by inea-ns of rubber tubing slipped over the end of the tube,'and the residuum, if any, is carried away by like tubing fitted on the end of tube K. l

It will be observed that a turn of the plug G closes or opens both the inlet tube F and the outlet tube C.' Preferably the passages l and L, are ot such size that not more than a quarter turn of the Cock is suiiicient to open or close the tubes. A slight turn (say a quarter) of the stopper D closes the outlet tube only, as may be desirable when a pres sure is to be produced in the bottle.

The apparatus illustrated is designed particularly for absorbing carbon dioxid or other acid gas and determining its amount, but of course can be used lor other purposes as well, as for example for washing. ln the former case the bottle is charged with suitable absorbent, and is weighed with its contents. rl`he gas .is then passed through, and the bottle and contents weighed again. The increase in weight then gives the amount of gas absorbed.

- The valve plug Gr being removable as readily as the stopper D, the apparatus is easily cleaned and rinsed.

lt is to be understood that the invention is not limited to the apparatus herein specifically illustrated but can be embodied in other forms without departure from its spirit as delincd by the following claims.

l claim:

l. An apparatus for gas-absorption and other purposes, comprising a vessel having a removable closure, gas inlet and outlet tubes connected to the lower and upper portions ot' the vessel respectively, and aA single valve connected to both tubes independently of the closure, to control both tubes simultaneously.

2. An apparatus for gasabsorption and lll) ter with .said outletI tube byrotating the A closure, a gas inlet tube eonneeted with the 'lower portion of the vessel, and means for delivering gas to theinlet tube and carrying gas away from the outlet tube, said nieans including a single valve controlling both tubes. l

An apparatus for gas-absorption and omer purposes, comprising a vessel having a neck B at its top, a gas outlet tube C leading laterally from the neck, a rotatable elosure D seated in the neck aiul'liaving an outletl aperture E adapted to be carried into and out of registry with said outlet tube by rotating the closure, a gas inlet tube F eonneeted to the lower portion of the vessel, a Valve shell J connected to the gas inlet and 'outlet tubes and having an axial diseliai tube K, and a Valve-plug G rotatable in l shell and having a gas-delivery tube ll a provided with a passage ll leatfling :fr the Said deliveryv tube into position 'for istry with the said inlet tube and a L extending from a position for regi with the said outlet itube into registry w the said discharge tube, wherein,v rotation the plug controls both the inlet und the outlet tube simultaneously.
