MILTON HENRY KAUFFMAN, OF CHICAGO, ILLINOIS.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 612,648, dated October 18, 189B.

Application filed July 23, 1897. Serial No, 645,678. (No model.)

To all whom, it may concern:

Be it known that I, MILTON HENRY KAUFF- MAN, a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Gas- Generating Devices, of which I do declare the following to be a full, clear, and exact description sufficient to enable others skilledin the art to make and use the same.

On the drawings which accompany like parts bear like designation throughout.

Figure 1 is a view in vertical section displaying the invention as applied toabicyclelamp; Fig. 2, a view of the central absorbent obstructor with its supporting rod and disk detached; Fig. 8, a perspective view of a cartridge-shell for the carbid.

Each lamp is designed to carry its own separate gas generator, the generator, as here shown, being removably secured in dependent position beneath the lamp-body Ct by slipjoint or like expedient.

The gas-generator 1) comprises in the main an internal retort to contain the charge of carbid and an outer supply-tank for the water. The two parts named are adj ustably united by screw-joint or the like, as at d. The tank incloses the retort and is properly located to insure the gravity delivery of water through the retort-bottom. At its lower end retort 01 carries a screw-cover 6, having a central tubular boss 6, tapered slightly, through which boss the water from tank 0 passes into the retort. At the upper or opposite end of said retort there is a retainingdisk f, carried by a dependent rod f. About the rod is Wrapped and secured the absorbent obstructor g. A bit of linen cloth Wound in roll form upon the rod f will serve.

Obstructor 9 projects beneath into the tapered boss e, so that on screwing cover e to position the boss will compress and constrict the cloth roll to better insure the desired seepage of water past the inlet-vent into the retort interior. By abutting against the top of retort dthe disk f on rod f resists the thrust of cover c as it is screwed on, and thus insures the constriction of the roll. To stop the further flow of water, retort d is turned at its screw-joint cl until dependent boss 6 (with perhaps the protruding end of roll g) is forced against the yielding seat 0, arranged tridge-shell filled with its charge.

opposite thereto on the base of water-tank c. The Water-supply being cut off, it is clear that the generation of gas will cease almost immediately thereafter. Since the absorbent obstructor extends directly through the mass of carbid, it is in central position to raise the water by capillary action and distribute it radially to all parts of the charge, thus insuring an even chemical reaction and a constant supply of gas through burner h and tip h. A disk d of felt or the like, set at the up per part of the retort interior, acts as a filter for the gas to screen out the moisture and solid particles.

- A cartridge-shell j, formed of tin, pasteboard, or other proper material, may be con veniently used and when employed serves to contain a measured charge of the carbid. The open mouth of said shell j rests in inverted position against retort-cover 6.. At its opposite end there is a central hole in the shell, into which is fitted a tube j, consisting of porous paper, &c. The tube projects centrally through the shell and affords ahousing to receive and protect the roll 9 from direct contact with the carbid.

Then the several parts of the generator are separated, the obstructor rod and roll f gare thrust through housing j and the car- Retort d is held upright toexpose its open mouth. The loaded cartridge is slipped therein and cover 6 applied, its dependent boss 6 constricting the end of roll g that protrudes. Having closed the retort, as described, it is simply inverted, together with its load, and screwed into place at joint cl, so as to be inclosed by tank 0. If united tightly together, seat 0 at the tank-bottom completely shuts the confronting inlet-port e. A minor turn in reverse withdraws said seat from the port a slight distance, but still sufficient to permit the tank-water to seep through the port and be drawn capillarily into the retort. In this connection I desire to refer to my pending application for United States Letters Patent, Serial No. 590,983, filed May 11, 1896, wherein I have broadly claimed certain tea turesshown and described in mypresent ap plication.

Obviously the details of structure can be varied according to the mechanics skill with out departing from the essentials of the invention.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In acetylene-gas lamps, the combination with the outerorinclosing Water-supply tank having a yielding seat at its base, of the internal retort for the carbid adj ustably united to said tank and furnished with a bottom inlet against which said seat may bear to shut off the inflow of water, substantially as described.

2. In acetylene-gas lamps, the combination with the outer or inclosing water-supply tank having a yielding seat at its base, of the internal retort for the carbid adj ustably united to said tank and furnished with aprojecting bottom inlet dependent therefrom and an ab- MILTON HENRY KAUFFMAN.
