AUTOMOBILE.

SPECIFICATION forming part of Letters Patent No. 672,941, dated April 30, 1`901.

Application filed December 18, 1899. Serial No. 749,671. (No model.)

To all whom, t may concer-n,.- y

Be it known that I, BENJAMIN F. JACKSON, of Cambridge, county of Middlesex, and State of Massachusetts, have invented an Improvement in Automobiles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to an automobile, and is mainly embodied in a generator and motor of novel construction and arrangement which are so disposed with relation to the body of the vehicle that the whole working apparatus can be readily removed from the vehicle, so that the same motor can be used without trouble for a number of vehicles of different descriptions.

The generator is provided with an oilburner,and the oil-receptacle, the said burner, the water-drum, the steam-generator tubes, the steam-drum, and the engine are all supported upon a portable frame, while the body of the vehicle is provided with a chamber or casing for the said frame, so that the motor and generator can be readily transferred from one vehicle to another, thus obviating the necessity of duplicating the most expensive part of the apparatus when a number of vehicles of different descriptions are to be used. The oil-valve and engine-valve are so connected as to be controlled by a single actuator or lever, so that both the steam and the fuel are cut olf at the same time when it is desired to stop the carriage, the burner being provided with an' auxiliary portion which only used sufficient oil to keep the generatorpipes hot, so that the carriage will start promptly when the main burner is started and the engine connected with the steam-generator.

Figure l is a longitudinal section of the body of a vehicle and a motor and generator applied thereto in accordance with the invention; Fig. 2, a horizontal section through the generator-casing, showing the generator and motor mainly in plan and the independent supporting-frame therefor; and Fig. 3, a side elevation of the motor and generator detached.

The generator comprises a water-drum a, communicating with a series of generating pipes or coils b, leading from the bottom of said water-drum and communicating with a suitable steam-drum c, connected with a pipe or duct CZ, which leads to the engine or motor e and also to the Water-drum ot, having an inlet-pipe d2 at the 'top of said water-drum, so that the pressure in the steam-drum and water-drum are equalized, permitting the water to feed into the generating-tubes b by gravity. The said steam-drum is shown as provided with a baffle-plate c2 over the steam-inlet, which prevents water splashed up from the generatorcoils from being blown through into the engine-cylinder.

Below the generating-tubes b is situated a burner f, which may be of any suitable construction or arrangement, the said burner being supplied with fuel through a pipe f2 from y hicle, the gearconnection not being shown,

since it forms no part of the invention.

The water-tube, steam-generator coils or pipes, and the steam-drum are all inclosed in a jacket or casing h, which also includes the burner f, the said jacket h being provided with outlet-tubes h2 for the products of combustion and being open at the bottom and provided with a deector 3, arrangedto project outward through an opening in the body of the vehicle and inclined upward to the rear, so as to create an upward draft as the vehicle moves forward and direct the products of combustion toward the generatortubes.

The oil-reservoir g is shown as connected with the outside of the casing h, and the several pipes are connected in such a way that the whole generating system forms, as it were, a single unit. The said parts, together with the motor e, are all supported upon a suitable framework, which is herein shown as formed of iron gas-pipe, (indicated by the letter 10,) and the said frame and parts supported thereon are adapted to be inserted in a IOO casing or chamber A2, formed in the body A of the vehicle. The said casing is provided with a hinged door A3, having openings A4 for the outlet-pi pes h2, so that the motor and generator may be completely inclosed after they have been placed in position, but may be readily removed for the purpose of transferring the generator from one Vehicle-body to another.

The valvesf3 for the oil and d2 for the steam are arranged to be simultaneously operated, the construction being best shown in Fig. 3, there being a common operating device m for the said valves, herein shown as a rack connected with a lever m2, pivoted at m3 and provi'ded with an actuating-handle m4. rIhe stem otl the valve f3 is provided with agear-wheel f4, meshing with the rack m, so that when the said rack is longitudinally moved it will properly operate the said valve, and a similar gear-wheel d3 is arranged to transmit the movement, as by a chain d4 and sprockets d5, to the valve d2, so that one operation of the lever m2 will open or close both valves.

The burner is intended to be provided with an auxiliary burner,(not herein shown,) which will supply sucient heat to keep up Steam when the vehicle is at rest, the valve cl2 controlling only the main burner, which is shut off simultaneously with the motor when it is desired to stop the vehicle. In starting up, therefore, the steam-valve and oil-valve both being opened, there is sufficient steam to start the vehicle, while the main burner then being placed in operation, being ignited by the flame of the auxiliary burner, the steam is generated rapidly enough to produce the power needed.

The vehicle is shown as provided with a steam-gage o and an oil-gage p, which are connected by couplings 02 and p2 with suit.- able pipcs,4the said gages being permanently connected with each vehicle-bod y and adapted to be disconnected from the motor and generator when a change is to be made from one vehicle to another.

I claiml. The herein-described driving apparatus for an automobile which comprises a waterreservoir or supply-tank; a steam-drum above the normal water-level in said reservoir; generating-tubes between said reservoir and said drum; aburner below the said tubes; an inletpipe leading from the bottom of said waterreservoir to the bottom of the boiler and an equalizing stealnduct leading from the top of the steam-drum to the top of the water-reservoir whereby water is fed to the boiler by gravity; and a. steam-motor supplied from the said steam-drum, substantially as described.

2. A driving apparatus for automobiles comprising a burner; a fuel-supply for said burner; a steam-generator; a steam-motor; valves controlling respectively the supply of fuel to the burner and the supply of steam to the motor; and a common actuating device for the said valves whereby they are controlled simultaneously, as set forth.

3. The combination with a vehicle provided with a chamber or casing to contain driving apparatus; of an opening in the bottom of said casing; a generator comprising a waterdrnm, generating-tubes, a steam-drum anda burner all inelosed in a suitable chamber provided With an opening at the bottom, the said opening being over the opening in the automobile-casing; and a delector to cause a current of air to pass through the chamber containing the generator-coils, &c., to direct the heat toward the said coils, substantially as described. I

4. The combination with a vehicle provided with a steam-gage, an oilgage, and a casing to receive driving apparatus; of driving apparatus comprising an oil reservoir and burner, a water-reservoir, steam-generating tubes, a steam-drum, and motor all mounted on a portable frame and contained in the said casing; and tubes leading from the steamgenerator and oil-reservoir respectively and adapted to be coupled with the oil-gage and steam-gage, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

BENJAMIN F. JACKSON.
