It will be observed that these openings are restricted in size and are considerably. below .the level of the partition 7i. f 'i The cover d is detachably secured toathe casing by the spring clips [which have' suffiyet permit ready removal of the cover with;

What I claim is:- v 1. In a portable oxygen generator f for medical purposes and the like, a cylindrical Y casing, a vertical take-off pipe secured within said casing at one side thereof, and a horizon.- tal tap connected to said pipe and extending through the wall of the casing, in combination with a vcover for the casing, a tube form' ing a gas, collecting chamber depending from I 20 the cover and open at its lower end, areceptacledetachably secured to said tube, a partition said receptacle, water` passages through said partition, and a bent sheet oi` metal secured to one side of the said tube.

toform an auxiliary chamber adapted to rit -overthe vertical takeoff pipe when the cover is in ace, the Walls separating the gas collectingnamber from the auiriliarychamber having a restricted passage, substantially as described.-

.2. In a portable oxygen genepator for r medical-purposes and t e like, a casing; a flanged cover for said casing, spring clips adapted to hold the cover to the casing, a gas collecting chamber depending from said cover, a vent in said cover outside of the said chamber, a. receptacle detachably secured within said `.chamber by a bayonet joint, provided with the spring cli vo, a hori- .40 zontal partition in said receptac e, adjustable Waterpessages through said partition, a vertical takeoff pipe secured Within the cylindrical casing at one side thereof, a hori- -zontal ta connected with said pipe and extending through the wall of the casing, an
