withinwhich pipe l! the small steam-pipe K passes to the steam-jacket, and is secured to the branch-piece M M in the same brunch with the steam-pipe t, and connecting with the pipe t, so as to convey the live steam from the boiler, h v the tube K, within or through thc eductiou-pip4.l L 1o the steam-jncket E, as shown iu figs. l and li;
The steam from the steam-jacket having heen returned to Ill, M, passes out through the lower branch ot' M M and the 'valve X, and then outward, or into thc smoke-box of the locomotive, hy the pipe O.
'lhe valve N closes upward, and is held to its seat by ihcspiral spring I, which.4 should have sutiicient force to resista pressure ou the valve of about one pound; the purpose' o t' this valve being to keep a uniform pressure, and consequently a uniform heat in the steam-jacket E of the apparatus around the conducting-plate and super-beatiiig-chamber. i The hot vapor of thcgasoline passes up from the superheaiing-elunnber (L), through a small passage, which iscontrolled by a conical valve on the stem D, and then up through a passage, which is controlled by the 'hanging `valve T, into the regulating-chamber i w -w in the lower part of the shell or, case U G, below the iicxiblcdiaphragm U. The hot vapor from below this diaphragm enters into and passes up the tubo v r, which is attached to the upper side of the diaphragm, by means of the lateral branches in the shank ofthe valve '.l, as shown in iig. l.
l '.lhe contracted veut ofthe pipe 'c 1: is directed centrally up thc carhuretting-pipe li B, which isattached to the diaphragm-case C, and carrying, at top, the burnerA ofthe hea-gldight.
Around the hase of the pipe B B, and in the same level with the vent of the. interior pipe c r, are a few small holes to admit the atmospheric air to be mixed with the vapor of the gasoline as it passes up fron the vent ofthe pipe c r. llhe burner A is of the:ligand-pattern, andl should he of large size, and is enclosed hy a glass chimney, as usual, which chimney is attached to and carried by the enclosing-pipe S S, tig. l.
In. the lower part ofthe enclosing-pipe S S, that is, below the reflector of the .head-light, there are numerous holes, for the admission of air to support combustion at theburner Aand to supply the carburetting pipe B; the air so drawn in, being heated in its passage up between the enclosing-pipe and the diaf ihlagm-case (i, these parts being at a high heat, from heir proximity to and immediate connection with the .st-eaimjacket E.
The apparatus being thus arranged and constructed, and the tank 'm heilig filled or nearly so with the hydrocarhonsfiuid, on turning the cock a, the fluid will run down from the tank through the' pipe H" into the genelating-cluunber G, tig. l.' If now steam be admitted by the tube l( into thc^steam-jacket E, the conducting-plate liand the whole of the apparatusl connecting with the said steam-jacket, including the enclosing-pipe S S', will become highly heated, and the pendent commuting-points ofthe plate l passing downward into the fluid continued in the chamber G, will quickly vaporize the upper portion of suoli Huid, and the vapor so evolved will pass upward through the small holes or, vent-s in the eonductingplate 11, into the vsuperheatingchainber Q immediately above it, as indicated by the arrows atsuch part in fig. 1.
The chamber Q being i'nll ofthe super-heated vapor, and the. valve ll) being open, the vapor will pass up into-the regulator-chamber -w w, the passage to which chamber is' controlled by. the hanging valve .l, attached to the cent-re of theilexiblesdiaphragm U, solthat any increase of pressure ou the. diaphragm will tend to drawnp and close the valve .L. The vapor passes from below the diaphragm up andthrough the tube c lr;,avl1icl1 is also attached to the centre of the diaphragm, from which tubeV or tip o c, the hot vapor issues with a high velocity through its contracted 'vent directly up the centre of the tube B '13, and'cansing, by such velocity, a vacnous actionV at the base of the said pipe, which, in turn, causesfthe atmospheric air to rush into said pipe through thefperforatons at its. base, which air is immediately carhurettcd or combined with vthe, gasoline-vapor, and passes upto the argand-burner A, as a gas of great illuminating power.
The atmospheric air, whichenters the carburettingtube 1i B, and which passes up within the enclosingpipel S S, to' support the combustion ofthe gas at the burner A, is previously heated by passing up through the4 peribrations in the lower part of S S, and between it and the shell C of the regulating-chamber, allof which parte are maintained at a high heat by their connection with the steam-jackef, aS already explained. i f The apparatus is made `self-regulating, by means of the valve l and the iiexble diaphragm U, for the vapor pressing upon the'under side ofthe diaphragm, will lift this valve, and thus partially close the opening or passage for the vapor, and thereflbre the greater the pressure ol` the .vapor upon the diaphragm, the vent or'passage at t-he valve will be so much the `more contracted; that is, the size of the vent will be inversely as the pressure of the vapor, and the relation of these parts being thereby so adjusted, that, while. the valve D remains open, the same quantity of vapor shall, at all pressures, pass up to ,the burner, and thus.
maintain the dame at a uniform height and power in the lamp.
An impro red l'orm of regulator is shown in fig. 3. In this the diaphragm is made very light, its tension being such as to allow the valve t ,to be opened suf c'iently to give a llame of only about halt' an inch in height, at the burner of the lamp. I
The valve i, in iig. 3, it will bepbservedorresponds with the valve 'I in lig. and is acted upon by its diaphragm g g in the same manner that T is acted upon by the diaphragm U; butin fig. 3,4m adjustable spring is combined with the diaphragm, and'thus allowing the size of the flame of the lamp to be adjusted or regulated to any desirable height or power.
The socket a a, which containsthe adjustable spring, ismade to protrude or project through the enclosingpipe'S- S, iig. 1, so as to be within reach when required.
In the socket a a is a sliding tube,j,' having a shoul-` der or bearing for the spiral sprlng at the outer end, and a small central hole for a steady bearing'to the sliding rod e, which rod has an enlarged'portion at its inner end, to llt the tube j, and forming a. bearing for the spiral spring to' act gn, which enlarged portion of4 the rod e, also bears upon the centre of the diaphragm ing the lianie, at the burner of the lamp, to any de` sired height. .lhe sliding tube f is then secured toits place by the compression of the nozzle ofthe part a upon it by the screwed nut j, the screws being taperA in both, and the nozzle of a being quartered to admit of compression, as shown in fig. 4l
To prevent the lea-king `Jf the steam from the steamjaeket E, lig. 1, into the vapor-passageawe introduce the bush or lining R R, around the valve-stem Dm the casting P l?, and to whiclrit is secured, as shown in iig. 1, and leakage of gas around the valve-stem 1)V is prevented by packing under the gland J, m the usual manner.
The gas is admitted to or shut off from the burner A by the valve D, which is rotated in its screwed bearing in R R for that purpose, by the hand-wheel at the outerend o'f the stem, as shown in fig. 1. We hereby disclaim anything in this application that may in any way couict with an application now pending for a somewhat similar invention. Having thus described our invention, What we claim as new, andA desire to secure by Letters Patent ofthe United States, is-
1; The combination of the elevated tank with the steam gas-generator and the burner of the lamp, substantially as described. 2. The arrangement of the perforated metallic couducting-plate F, between the generating-chamber G and the superheatiug-chamber Q, substantially as described.
