MOTOR-PRESSURE GENERATOR,

4 SPECIFICATION forming part'of Letters Patent No. 324,828,dated August 25, 1885.

I Application filed October 13, 1884'. (No n1odel.)

i .To all whom it may concern.

Be it known that. I, OSCAR GASSETT, of Boston, countyof Suffolk, State of Massatfiusetts, have invented an Improvement in otor-Pressure Generators, of .which the following description, in connection with the accompanying drawing, is a specification, like let ters on the drawing representing like parts.

My invention relates to an apparatus for generating fluid-pressure which may be employed in actuating mechanical motors or engines. v

The invention consist-s,es'sentially, in ap'paratus for the-combustion, in a confined space or chamber, of a combustible vapor or gas, the gases or heated products of combustion from which may be employed to act-uate'by their pressure or expansion an engine or motor of any suitable or usual construction.

The invention is embodied in an apparatus consisting, essentially, of a strong tight cham ber, shown astubular or cylindrical in shape, and a second closed chamber, shown as contained within the main chamber, the second or, internal chamber, whilethe apparatus is in operation, being exposed to the action of a flame,by which it is heated to ahigh temperature. The said internal chamber is supplied with w ater, which is converted into steam th are in, andtthe steam is employed in connection with-a reservoir containing a combustible liquid-such, for instance, as the usual hydrocarbon compounds-#0 produce a jet of inflammato be set in operation.

ble' gas or vapor, which is ignited and produccs a flame, by which the said .chamber is heated to generate the steam. Suiticient air, preferably also heated by the flame, is supplied to support combustion, and the combined heat combustion of the hydrocarbon liquid with steam and air may be employed to actuate a mechanical motor or to perform work by their pressure and expansion.

Appliances are provided for producing steam in order to start the flame, and also for igniting the saidflame when the apparatus is longitudinal section under press The heated The drawing shows in an apparatus for generating gases ure embodying this invention.

and expanded gases are containing oil or other gases or products derived from't-he before described.

generated in a main be of any chamber or reservoir, (4, which may suitable size and shape. chamber, 1), of cast or malleable iron, is shown as contained within the main chamber, and

when the apparatus is in operationwill contain steam under high pressure, generated as hereinafter described, and the said conveyed therefrom through a pipe, .2, to a nozzle or injector apparatus, d, from which it issues with greatvclocit-y and operates in the well-known manner to reduce the pressure in a pipe, 6, communicating with a reservoir, f, hydrocarbon fluid, which, when combined with steam and air, producesa combustible gas or vapor. 'The' flow of combustible liquid through the pipe 6 is controlled by a cock or valve, 9, sothat the proper amount may be combined with the issuing jet of steam, producing a combustible compound, which, when ignited, will burn with a flame that acts upon the internal chamber, b, heating it sufiicicntly to maintain the generation of steam therein aslong as a suflicientsupply of water is kept up. Air is admitted to the nozzle (1 in sufficient quantities to support combustion of the gaseous jet A steam-generating steam is I issuing from-the'fiozzle d through a pipe, It,

the said air being forced in under pressure, if necessary. The pipe h, preferably, is also ex: posedto the action of the flame, as shown, so that it combines with the inflammable gas or vapor-in a highly-heated condition, More air may be admitted essary, the amount being cont-rolled by a suitable: register.

In'orde to provide steam in the chamber b for producing the jet at first, before the flame has heated the chamber 1), an auxiliary Stealnf generator, 70, her I) by pipes m and by a'suitable valve, 0,

a, the latter controlled the said auxiliary generator kbei'ng heated in any suitable manner, as by the flame of a lamp,or alcohol contained in a saucer or chafing-dish, k, for small appa f ratus, until steam is generated therein at sufficient pressure,

whenthc said steam will flow through the pipem to the chamber 1) and pi pc 0, when it will produce the combustible jet, as I The said jet thus produced is connected with the said cha'mthrough an opening, i, if necmay be ignited in any suitable manner. As

shown in this instance, the igniting device consists of a loop, a of fine platinum wire mounted on a spindle, 12 provided with a suitable handle, 2', by which it may be turned from the outside of the chamber a, the said loopp being connected in circuit with a suitable battery or generator of electricity, B. When the flame has been burning for a short time, the chamber b will be sufficiently heated for the generation of steam therein, after which the heat may be removed from the chamberk and the "alveo opened, admitting water to the chamber b in sufficient quantities to maintain the jet in constant operation. The pressure in the chambers b and k is equalized by the steam passing through the pipe m to the upper portion of the chamber k, so that the water will flow to the chamber b by gravitation; its amount being regulated by the valve 0. The flame burning at d produces gases at a very high temperature, which, when confined, as in the chamber a, are under suflicient pressure to actuate a motor, the said gases being conveyed from the reservoir a to the said motor, where they expand, and, in partiugwith their heat, produce mechanical work. But a very small amount of steam is required to produce the proper jet atthe nozzle (1', and as more steam may be generated in the chamber b, the surplus may be discharged through apipe, p, terminating in'a nozzle within a concentric nozzle, r, connected with a partition, t, in the chamber a, so that the jet of steam issuing from the pipep will tend to force the gases from the side of the partition t, where they are generated, into-the portion a of the'chamber in advance of the said partition, where the pressure will be greater, and from which the mingled steam and gas may be taken to supply the engine. A check-valve, t, in the partition i permits the gases to flow into the portion a of the chamber when no steam is issuing from the pipe 1), so that the pressure is nearly equal on both sides of the partition. Vfhcn the chamber k is nearly emptied of water, an additional supply may be introduced without interrupting the feed to the chamber' b by means of a chamber, k, the lower portion of which is connected with the chamber k by a pipe, n, containing a cock, n". The upper portion 0f.,the chamber 1: is connected by a pipe, m, containing a cock, m, with the pipe an, communicating with the'steam-chamber b and upper part of the chamber k. When the cooks n 11: are closed, the chamber k is cut off from the chambers k and b, so that the said chamber k may be readily filled. Then, by.

(losing the inlet to the chamber In and openi ng the cooks m n,- the steam-pressure in the chambers k and is will be equal, and the water will flow by gravitation from the chamber k into the chamber k. The chamber a may be provided with an outlet-pipe, u, controlled by a valve, u, which may be opened when the apparatus is being first set in operation, in

order to atford a read escape for the products of combustion, so that there will be no pressure to resist the entrance of air and combusti ble liquid until the combustion is thoroughly under way. Aremovable plate or bonnet, I, may be provided for affording access to the nozzle d, and the said plate may be removed for the purpose ofigniting the flame, if desired. A block, w, of refractory material will preferably be placed in the path of the flame issuing from the nozzle d, the said block becoming very highlyheated, and thus retaining sufiicient heat to ignite the gaseous jet after a momentary interruption in the flow of the gas, in case one should occur. The block 10 is provided with a hole for the passage of the flame through it.

I claim- 1. In an apparatusfor generating gases under pressure, the combination of the following elements, namely: the main casing or chamber for containing the gaseous products, a steamgenerating chamber, a reservoir for combusti-' ble fluid, and a nozzle communicating with the steam-generating chamber, the jet of steam from which nozzle acts on the fluid supplied from the reservoir, whereby in the operation of the apparatus a jet of combustible gas or vapor is produced, the flame of which acts upon the steam generating chamber, substantially as described.
