.To all whom t may concern Be it known that I, Umain: S. MAXuL'ot" the city, county, and State of New York, have invented a new and useful Improvement in Gas Head-Lights for Locomotive-Engines; and I do hereby declare that the following is a. fulland exact description thereof, reference being had to the accompanying drawings, making part of this speciiication, and to the figures and letters marked thereon, and in which- Figure l is a vertical section of the a Fig. 2, vertical section through the line X Y in Fig. 3; Fig. 3, a top view or plan ot' the apparatus. The saule parts are' indicated by the same letters ol' reference in all the figures.

, stalling-'box B My invention relates to an improvement in the inode of generating gas from hydrocarbon luids by the heat of an auXilia-ryilame, and in vseparatingv andfusing ibrmhat purpose the heavy or refuse portion of the Huid. In this apparatus the hydrocarbon fluid is contained in a tank or reservoir, which may have an ele vated position within or upon the headlight case, so that the iiuid may run down to the generating-chamber by its own gravity; or it may be placed in any convenient location and be forced into the generatingcham-ber by the action of compressed air within the tank, or otherwise; butin all cases the tank communicates with the generator by means of a pipe, which connects the lower part of the one with the lower part of the other; and whemthe tank is secured to the head-light case make this pipe with a telescopic `ioint, as shown in Figs. l and 3, inwhich the pipe A, connecting with the tank, passes centrally through the and within the pipe U,which is attached to the apparatus and connects with the generator D by the pipe E, thus ermitting the gas apparatus to be drawn forward or outward sufieiently for all the necessary' purposes of manipulation or adjustment without disturbing thetank.

The generator D is a conieally-shaped vessel, and is placed in the apparatus with the small end` downward withinthe base or pedestall?, to which it is screwed by its upper or larger part, as shown at a a, Fig. l, and immediately below the heatingLchaniber G.

Attached tothe heating or ilanie chamber through the pplicution for reissue'ficd September 2, 1879.

G, and within the generator D, is a pendent tube, H, connecting with the lateral tuheJ by means ot' the small additional generator c, for a purpose to be presei'itlybexplained.

Within the generator D, and around the pendent tube H, there are a number of paral lel disks vof ne wire-gauze or perforated sheet n metal, e e, which are held at proper distance apart by means of Atubular thimbles cl around the pendent tube H, as shown in Fig. 1". The lowest thimble of the series, being screwed to the end ofthe tubesecures 'all' the disks in position; The object otthese disks is to prevent the agitation or disturbanceI of the fluid within the generator by the motion of the locoinotive. The lighter portion of the hydrocarbon fluid or gasoline (which is the most valuable for illuminating purposes) ascends meshes or perfor-ations of these upper part of the generator,while the heavier and comparatively worthless por tion passes up from the bottom of the gener ator through the pendent tube H, small generator c, and lateral tube J, to the back chamber, l1, and then, by the small passages f, through the contracted rent g, which iscontrolled and closed, when required, by the conical screwvalve K, passing through the stuffing-box h and screw-tapped through a support near the iet-critics, so that any contraction of the parts in cooling when theralie is closed may act only upon that part ot' thc rod between the jet-orifice and the support, while the remainder of the rod may adjust itself by sliding through the stuffing-box, and is rotated by the small hanrtwheel le, the said conical valve having a central needle-like projection, which passes through the central vvent, g, when the valve is closed, and which is withdrawn, or partially so, .ou opening the valve, thereby keeping the vent g at all times free from obstructions and in working order.

Immediately below the pipe J is a small spoon-shaped disk, L, for the purpose of hold ing alcohol, or alittle of the gasoline may be allowed to run into it by opening the screw-valve disks to the K, and upon this being ignited, so as to start' the apparatus, the tube J will become hot, and thereby vaporize the fluid within it, and the vapor thus generated passes up to the small hack chamber, Zi, and by the small passages j',

IOCI

l through the contracted vcntg, into the burnin gi l, which is secured in the desired position by the set-screw m,by means of which adjustingpiece the perforations may be reduced in area to any required degree.

The heat ofthe flame in the chamber G passes by conduction to all the parts of the apparatus in contact with it, and in this way the upper portions of the generator D and pendent tube H are made hot, while the lower portions of the generator are kept cool by exposing it .to a draft of open air, the bottom of the head-light case being cut away sufficiently to permit the air to act upon it, as shown at P, Fig. l, and the base or pedestal F is made with large ventilatingopenings for the same purpose. The vapor formed in the upper part of the generator D passes up through the passager., which is controlled by the screw-valve Q, passing through the stalling-box p, and rotated bythe ysmall hand-wheel q. This is, like valve-rod K, supported near the point by heilig screw tapped through asupport adjacentto the point, as shown. From the passage n -the vapor passes up into the chamber R beneath the screen s, which is made of line wire-gauze and perforated sheet metal placed together; or either may be used separately, if preferred,the object` being to pr vent the passage of ,any feculent matter to he contracted vent t that mayhave come up with the vapor from the fluid in the generator, and which, without such screen or its equivalent, is liable to close or im pair the action of the vent. The vapor passing through the contracted vent t at a high velocity draws sufficient atmospheric air into the mixingtnbe S through the small holes at its base to make, with the vapor, an yilluminating-gas of great power, using for that purpose an Argand burner, 'Linclosed by a glass chimney, V, mounted upon the air-tube W, which is attached to the heating-chamber'G, and inclo'sing the chamber 1t and mixing-tube S, and has numerous small holes at its basc'for the admission of air as well for the mixingtube S, to be carbureted by the vapor, as to support the combustion of the gas at the burner T.

Beneath the burner l in the air-tube W, I place a disk of perforated metal, Y, through which the'air passes to the burner T, the ohjcct being to prevent the flame from the burner passing downward within the air-tube \V in the event of vapor escaping by the air-vents at the base of the mixing-tubc S.

wheel q controls The air-tube lV being` attached directly to the heating-chamber G, its lower end becomes very hot, and thereby heats the air in its passage through the small holes provided for that purpose at its base. The heated aircombining with the gas from the burner, enables it to be ignited at the top ot' the glass chimney, which is a matter of very great importance, as

Vit obviates the-necessity of removing the glass chimney from the lamp preparatory to lighting it, as must be done when cold air only is used to support combustion, because cold air condenses this kind ot' gas. the sub gas apparatus by its handwheel k The valve K ot' So controls and extinguishes, when required, the

flame of the burning-tube M in the heatingchamber Gr, and the valve Q by its handand extinguishes, when required, the illuminatingamc at the burner T,

and the two valves conjoiutly regulate the flow v of the iluid from the tank to the generator D.

The apparatus which Ihave herein described has been found to work well in practice, and is of cheap and durable constrnction,'and not liable to get out of order, and is particularly designedito be attached tothose head-iight cases and reflectors which have been construct-- The arrange,
