MARK S. RIGHADSON', both ot' Rutlandtin the county of Rutland and State of Vermont, 'have invented certain new and useful'linprovements in Gas-Machines or Apparatus forxGeneratlng Illuminating-Gas; and we hereby def clare the following to be a full` clear, and exact description of the saine.

Our invention relates to the application of motive power to machines generating illuminatinggns b ythe passage of air through a medium which charges it with hydrocarbouyapors. To this effect air is forced through a vessel containing the hydrocarbomeitherin a liquid or aeriform condition, in such manner and by means Awhich insure the air ,becoming ot' suitable construction ,a blast-wheel or airpump or equivalents actuated by weight or sprin g-power mechanism The former modethat is to say, the forcing ot air by means of a Iweight-is purticularlyapplicableto stationary machines ot` limited capacity and calculated to `run foracomparatively short period of time, while the latter-i. e., in' which the air is impelled by mechanism actuated bya springalthough both applicable to stationary and portable machines, loses its advantages when ap,- plied to large machines. From thisit will be seen that the gas-machines as heretofore constructed are not adapted for use in large hotels, yrailroad-trains, stealnboats, factories, and other like establishments without the inconvenience attending the constant winding of the springs or adjustment of weights in order to maintain a constant tlow of gas.

The object of thisinveuiion tnererore is to. remedy this delciencyand-we .have accomplished this by making 'use of the steam generally found iu such places, or ot' the gas generated bythe machines, to operate the airforcing apparatus in the manner substantially as hereinafter explained. ,train purposes we provide the locoinotive-engine, at a part accessibleto and so as to be under the controlof the engineer, with a steamcyli'ude'r receiving its supply of steam from the' locomotive-boiler and workingalittle air-pump pressure and regular Thus, for railroadwhich forces -theair through a vaporizer .of suitable construction, or, preferably, one constructed in accordance with our invention for which an application for Letters Patent of the and furnish the head-lightand through all/the passenger-cars. By" this arrangement .the A pressuremay also be regulated by the enginee'r by his working the pump with vmore or less speed, as circumstances may demand.

In cold weather, when there is danger ofthe illuminatiuggas condensing, or of the duid sluggishly evaporating, we use heatersfsuch assand-baths or hot-water tanks-in which the 'aiippiuay be coiled before' passing into the' evaporuting-vessel. rEhe air passing through the coil is heated to the requisite temperature to facilitate the formation of hydrocarbon vapor in its passage through the fluid and to prevent the condensation -ot' the gas formed. Other means-such as the placing ot" the vaporizer in a heated medium, or the laying of the pipein contact with the boiler or [ire-box, &c.- may be adopted.

In the accompanying drawing we nave shown a pipe which maybe used both in summer and winter. At a the pipe branches oit' into two pipes,c and d, both of which are provided with cocks g and It. The branch d, being longer, is coiled and placed in a l1eater,.while the branch c passes outside of the heater and connects atv bwitli the main pipe. From this arrangement it will be understood that when the outside temperatnreisinsufcientto maintain 4tle volatility of the uid; o'r to prevent the' gas from condensing cockg is shut, causing the air to pass through the ooil,andconseqnently through the heater, before it can reach vthe vaporizer and, vice versa, when the outside temperature is warm, then the cock h is closed and the air allowed directly to pass to the vaporizer, and thence tothe burners.

We have given in illustration ot` our 1u vention the application of steam as motive power in railroad-cars and on locomotives; but it will l' be understood that a precisely-similar arrangement can be employed wbeneverthere is a local boiler, as in hotels, factories, Snc. The ar- .-pnwer which suppl rangement of pump may' be that which cccupies least space., und that;` which is of the sim 'pieni'. csnstructiou, and. most easily put iu operation ssd regulated. The arrangement we gire preference to is securing the steam and; si! cylinders tcsiiediate commento both. The two pistons belonging respectively to the sir ami steam cyiiuders are coupled, being mounted; upon the same rod whose movement, by means of an arm and cams or stops on the valve-rod, is transmitted, to actu nte thevulves in Vthe stesnmyliuder and in the aircylinder. I".We do ust. wish to be understood as confin- -ngourselves to this arrangementofstesm pump, manyother :arrangements may he fcund sui mic and convenient.
