v The schedule referred to in these Letters Patent-and maldng part of the-la'mc.

To all whom. it may concern:

Be it known that I, FRANKLIN T. GBIMES, of

Liberty, in the county of Clay and State of Missouri,

have invented certain new and-useful Improvements in Lamps, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawing forming part of this specification,

' and which represents a sectional elevation of .a' lamp constructed in accordance with my 'inprovements.'

My invention consists- First, in a certain combination of a main oil or fluid-reservoir, arranged to. form the outer portion of the body of the lamp, with a wick-chamber arranged in the base of the lamp, and supplied with oil or fluid from the main reservoir by a tubular'connection or connections betweenthe two, together with an airchamber or passage extending'fi'om the base of the lamp to the burnerwithin'orthrough the main reservoir and outside of the wick-chamber, whereby not only the main .body of oil or fluid is separated from -the wick-chamber, but the weight of the oil or fluid in the wick-chamber is made to give-steadiness to' the lamp, and a current of cooling air is circulated up through the main reservoir and around the wickchamber and its tube, which, in the use of certain oils or burning-fluids,contributes to safety.

The invention also includes the combination of an automatic valve or valves with the main reservoir and wick-chamber, for controlling the supply from the reservoir to said chamber, in such manner that when the lamp is burning or occupies an upright position ingress is kept open between said reservoir and charm ber,-bnt when the lamp is inverted or: any explosion takes placein the wick-chamber. communication is automatically closed between the reservoir and wickchamber, and connection thus cutoff with the main body of oil or fluidin the lamp. p

The invention likewise embraces an automatic .valve for opening and closing the air-orifice usually made in the cap or nozzle,.thro'ugh which the main reservoir is supplied with oil or fluid, in such manner that. in case of the lamp being upset, oil or fluid is prevented from escaping through said orifice.

The invention also includes a certain arrangement within the oil-reservoir, and between it and the airtube or passage that supplies the flame, of a safety water-chamber for extinguishing the flame-in case of the upsetting of the lamp.

Referring to the accompanying drawing .A represents the oil-reservoir, which is made to form the body of thelamp or outer portion thereof,

and which is in connection, by one or more tubes b, with the wick-chamber B, that is arranged in the base of the.lamp, and forms a secondary reservoir or chamber for the oil, which by its weight is thus made to contribute to the stability of the lamp.

The tubes b are controlled above and belowby connected spherical or other suitable valves d d and d d. The upper onesd of these valves are grooved or otherwise constructed, so that, when down on their seats,

oil will trickle past them into the, wick-chamber, but

the lower valves d are-.made close fitting, so that,.

when thrown or forcedagainst their seats at the bottom ends of the tubes 1), either by explosion within the wick-chamber or by the upsetting of the lamp, they shut off communication between the wick-chamber and main body of oil in the reservoir A.

A similar-provision is made in the screw-caper nozzle'O, through which the oil is fed into the reseryoir-by fitting the air-orifice e therein, through which air to produce the necessaryatmospheric pressure on thcsnrface of the fluid in the reservoir to secure flow isseoured, with a valve or double valve, ff, that, when the lamp is .in an upright position, allows of air-entering through said orifice, but that closes-fromwithin to shut or escape of oil or fluid .when the lamp is inverted or partially so. I

' D is the wick-tube, andfllfl an air-tube or passage for supplying the flame with oxygen. This air-passage is supplied from below, as by side orifices g in the outer portion of the base, and surrounds the wickchamber B; also passes up through the oil-reservoir, separating the wick-tube I) from contact therewith, and serving to keep the oil in the reservoir cool.

Arranged within. the reservoir A, and surrounding the air-tube E, is a safety water-chamber, F, open at its top, and that serves, in case of the upsetting of the lamp, to extinguish the flame.

' By the arrangement of this watcr-chaniber between the oil-reservoir A and wick-tube oi passage E, the air is kept purer and cooler in its course to the flame, and the fluid in the reservoir correspondingly cooled.

The wick-tube D- is of such construction, or so restricted as regards its support, as to be capable of springing toward or from the wickoperating wheel or lifter G, arranged in the upper portion of the lamp, on one side only of the wick-tube, into which it projects to establish hold on'the wick.

On the opposite side of the wick-tube is an adjusting-screw, H, capable of operation from the'exterio'r, and serving to spring the wick-tube toward the lifter to swinging or pendcntlamps as to table ones, or

those of a stationary character.

What is here claimed, and desiredmto be secured by Letters Patent, is,

1. The eomhination and arrangement relatively to esich other of the main leservoir A, the-secondary reservoir or wick-chamber B in the base of the lamp, the tubular-connection or connections 6, and the niptube or passage E, substantially as specified.

2."The combination of an automatic valve 01- valves, 11 d, with the tube or tubes 1), the reservoir A, and the Wick-chamber B,- for operation essentially as and for the purpose or purposes herein set forth.

3. The application of the automatic valve ff to the reservoir of alemp, so construetedthat air is ad- Witnesses i FRED. mums, Amrmm Kmmam.
