lMPROVEMET IN GAS APPARATUS.

The Schedule referred to in these Letters Patent and making part ofthe sme;

To all vwhom it may concern.-l

Be it known that I, ABRAHAM L. BOGART, of

the State ot' New York, have invented certain new and useful Improvements in Gas Apparatus; anddo hereby declare that the following is a. full, clear, and exact description thereof, refrence being had to the accompanying drawing making a part ot' this specification, in whieh-' Figure l is a side elevation of luy apparatus while in operation; A

lfigure 2 is a central longitudinal section of the saine; and

lfjgurc 3 is a like view of a retort for combining oxygen l'rom the air with ordinary coal gas.

Letters ot'like name and kind refer to like parts in cach otthe figures.

My invention has for its object thc conversion of hydrocarbon liquids into a Iixcd gas for heating, cooking, and illuminating purposes; and

.lt consists, principally, in the peculiar construction of tlleretort, and of its adaptation to and combination with the burner, substantially as ishercinafte'r shown.

lt also consists in the construction of' the reservoir for containing alcohol for use in heating the retort, and in the adaptation of'saidfrcservoir to the burner, and its combination with the retort, substantially as is hereinafter set forth.

It i'nrthe' consists in the combined burner, retort, and alcohol reservoir, coiistrnctcd and arranged substantially as and ior the purposehereinafterspecified.

.lt finally consists in thelpeculiar construction of the illuminating burner, by means ot which it is adapted to the nseof the gas generated by the machine, as is hereinafter shown.

A represents an annular metal ring, having secured to and projecting downward. from its inner edge a short cylindrical iange, c, provided upon its inner surface with a female screw-thread, while from the outer edge'ot'snid disk projects, upward a second flange, a', within which is placed ai cylinder of reticJul-ated shcct lnctal B, having a hcigbt equal to about-twice thatoi' said flange, and a dian eter somewhat less than the space between its walls.

Resting upon the upper cud 0f` the cylinder B is a cap, C, convex upon its ripper` side, and provided upon its outer edge with a flange, c,'which projects downward and slightly outward, (as shown in tig. 2.) A boss, c', projecting downward from the center of said cap,A contains one end of a rod, 1), thc opposite cud oi' which passes downward into a. cross-bar, E, spanning'the opening inthe disk A, and serves to bind said cap, disk, andthe cylinder B rmly together.

Secured within, and projecting vertically downward from the cylindrical flange a, is ashort pipe, F, thc

lower end' ot' which is reduced in size about one-half,

followiug-dt'zscribed incassare employedfor vaporizing hydrocarbon oils:`

Secured 'uponr the outcredgc of the cap C, and forming part ofthe same, is a circular chamber, G, which entirely surrounds said cap, and is provided upon opposite sides with suta-blcsockets for the reception of the threaded ends of'two pipes, the first of which, H,' communicates with the reservoir for containing oil, while the second pipe, l, extending outward, down- 'ward, and inward, terminates iu aver-tical branch, K immediately beneath the center ofthe burner, the upi per end of` said branch l being provided with a smalb opening, x, f'or the passage of gas, while its lower end is inciosed by means olf a screw-cap, k.

An' annular cup, L,- surrounds and forms a part of` the flange c of the baseo t' the burner, anda similar cup, M, is placed immediately beneath the vertical portion of the pipe I. A packing of asbestos and wire-gauze, h, being placed within the pipe H, between the burner andthe reservoir, the device is ready for operation as follows:

. The cups L and M being filled with alcohol, the latter is ignited, and, burning upward against the pipe I and thc chamber G, beats them rapidly, so'that, by the time that the contents ofthe cup M is burn'ed out, oil may be admitted from the reservoir, The oil, passing through said chamber G and pipe I, becomes vaporized, and, upon issuing from the burner, is ignited by thc burning alcohol within the cup L.

In from three to tive minutes thc chamber or retort yGr attains a. cherry-red heat, after which the oil passing through, 'is converted into a-fixed gas, suitable -for either heating orilluminatiu purposes.`

As the gas formed by this met lod is too rich for use in an illuminating burnerv that will pass over two feet per hour, it becomes necesary'to em ploy the following-described construction A short nipple, O, having in and through its np per end a small aperture, c, and provided upon its cxterior surface with a male screw-thread, is secured upon a. pipe, P,leadiug from the retort. An ordinary pipe F should be placed at a short distance above the brauch K, so that air may enter freely within said pipe. In order that the'pipo F 'may be secured in' such position, two lugs, W, are attached to the branch K,

and, projectingupwardl upon` opposite sides of said pipe, are secured thereto by means of wire passing through suitable openings within said lugs and around said pipe.

For heat-ing purposes, whcreordinary coal-gasis used, I have i'onndgreat advantage toresult from thc employment ofthe retort and burner shown in iig. 3, in which said gas is admitted through the pipe S into the open endv of the vertical pipe T, unites with an inward-Howing current of air, and passes into and through the retort G, where thc chemical combination between said gas and air is perfected.

Upon leaving the retort, the oxygeniz'ed gas passes down into the chamber U, beneath the burner, and upward through one 0imore reticulated diaphragms u, into and througlll said burner, having acquired, by

1. The retort G, constructed as described, and com binedwith the heating burner, substantially as and for the lpurpose specified.

2. The annular cup or alcohol reservoir L, coru-V bined with the retort G and with the heating bur-der, in thc-manner and for the purpose substantially as dcscribed.

3. The combined burner, retort, arid alcohol reservoir, when constructed and arranged substantially as shown aud for the purpose sct forth.

4. `'.lhe illuminating burner, composed of the perforated nipple 0 and the burner R, provided with the slot r, substantially as and for the purpose shown.

5. In combination with ,the gas-jetz and pipo or mixing-chamber F, thc air-passages f and f', substantiallyas and for the purpose set forth.

In testimony v'that I claim thc foregoing I have hereunto set my hand this 17th day of December, 1870.
