Application filed November 14, 1907. Serial No. 402,168.

To all whom it may concern:

Be it known that I, SAMUEL J. WEBB, a citizen of the United States, residing at Minden, in the parish of Webster and State of Louisiana, have invented certain new and useful Improvements in Motors, of which the following is a specification;

My invention relates to motors and especially to that class of motors in which the power is derived from the use of gases or a gaseous mixture under pressure, and my invention consists in means whereby to rapidly and continuously produce such an admixture by the combustion of a mixture of air compressed by the action of the motor, and a vaporized or gaseous fuel, as set forth hereinafter, and illustrated in the accompanying drawing, in which- Figure 1 is an elevation in part section showing my apparatus in connection with a motor and a compressor which may be of the rotary type and of any suitable construction; Fig. 2 is an end View; and Fig. 3 an enlarged sectional view of the mixer.

The compressor A and motor B m'ay be of any suitable character, but as indicated each is rotary, and the shaft of the motor is extended to operate the compressor which has inlets at as through which the air enters and a discharge pipe 9 provided with a suitable check valve 10 and leading to an air tank or receptacle E. With the motor is connected a supply pipe 12 through which the motor fluid passes.

In the construction illustrated in the drawing, the fluid supplied to the motor consists of the expanded gases resulting from the combustion of an admixture of air and liquid fuel or gas, and the expanded gases or motorfiuid thus produced are secured by introducing a mixture' of air and fuel through a pipe 3 into the combustion chamber y of a casing C, which communicates with the pipe 12, the air being carried under pressure from the compressor A or the reservoir E in which it is stored through a pipe 2 provided with a check valve 14 and with a suitable control valve 9.

The proper admixture of air and liquid fuel is effected in a mixer D. This mixer has a casing 16 communicating with the pipes 2 and 3 between which is a port 17 closed by a valve 5 and a channel 18 communicating with the pipe 7 is closed by a valve 6, the channel 18 and the port 17 being of different sizes and the valves 5 and 6 being so proportioned, and both being car-- a means of a handle 19, but to vary the proportions in consequence of difference in the character of oils used the valve 6 is carried by a screw stem 20 adjustable in the stem 4. The pipe 7 communicates with an oil reservoir H that'is provided with a check valve 21 and control valve 8, and the reservoir H communicates with the reservoir E through a pipe 23 provided with a control valve 24. By this means there is a constant pressure upon the oil tending to carry it forcibly to the mixer, and there is a constant pressure upon the'air tending to force it through the mixer, and when the control valves are properly adjusted the air and the oil will be carried to and through the pipe 3, and the oil will be dispersed or sprayed or atomized formin with the air a combustible mixture whlc'h passes to the combusion chamber y.

In the combustion chamber the mixture may be ignited in any suitable manner, as by means of an electrical igniter 26, and so long as the mixture is supplied and the heated gases withdrawn there will be a continuous combustion and the formation of a motor fluid under pressure, which passes to the pipe 12 and operates the motor B.v

In order to maintain the combustion within the receptacle C I provide a refractory body or material 29 which will become highly heated by the burning mixture, and in case of temporary cessation of the flow to or from the chamber will serve .to ignite the fresh mixture as soon as introduced. i

The air which is compressed in and forced from the compressor A will be stored to a certain extent in the receptacle E and prevented from flowing back by the check valve 10 so that the motor may be startedby means of the air thus held under pres-. sure in the receptacle E. In order that the motor may be started before any mixture is introduced and ignited, I make use of the tank or receptacle F which communicates with the pipe 12 through a pipe provided with a check valve closing against the pressure in the tank F, but capable of being .ceptacle 0 ma the tank E, and so as to insure a flow of air from the mixer into the chamber and control the same automatically.

It will be seen that by the arrangement I above described I am enabled to afford a constant supply of motor gases under pressure to the motor and to maintain the compressor in operation, and that the compressed air thus obtained is effectually employed to furnish the necessary amount of air to the mixture of air and liquid fuel, and also to vaporize or atomize the latter, but it will of course be understood that in some cases I may use gas instead of liquid fuel, or may vaporize the liquid fuel before combining it with the air. The motor thus put in operation by the continuous generation of gases as above described is suitably geared as by means of a pinion 30 with any part which has to be driven thereby.

It will of course be understood that the motor gases from the apparatus C may be used for operating a plurality of motors together or independently,'for which purpose one or more branch pipes 31 provided with control valves 32 may be used. The flow to the engine may be controlled by a throttle 40, While the air may flow freely to the compressor at all times, I prefer to cut it off automatically whenever the pressure tends to exceed that which is required. For this purpose I control the air inlet pipe 33 leading to the inlet at av by means of a governor valve 34 controlled by an ordinary pressure regulator 35, which is supplied with 1. An apparatus of the class described comprising a source of compressed air,

means for maintainin the pressure of the air below a predetermined amount, a working fluid generating chamber, a fuel supply ch amber, a mixer, means connecting the source of compressed air with said mixer, means connecting the fuel chamber with said mixer, means connecting the source of compressed air with said fuel chamber, means connecting said mixer with said generating ch amber, and a safet valve on said generating chamber and a apted to maintain the pressure in said generating chamber below the pressure in said source of compressed air.

2. An apparatus of the class described comprising a source of compressed air, means for maintaining the pressure of the air below a predetermined amount, a working fluid generating chamber, a fuel supply chamber, a mixer connected with said gener ating chamber, means connecting the source of compressed air with said mixer, means connecting the fuel chamber with said mixer, said mixer havingmeans for simultaneously varying the supply of air and fuel in fixed proportions, means connecting the source of compressed air with said fuel chamber, and.

asafet-y valve on said generating chamber adapted to maintain the pressure in said generating chamber below the pressure in said source of compressed air.

In testimony whereof I afiix my signature in presence of two witnesses.
