VAPORIZER AND COMBUSTION-CHAMBER FOR PETROLEUM-MOTORS.

SPECIFICATION forming part of Letters Patent No. 581 ,412, dated April 2'7, 1897.

Application filed May 22, 1896. Serial No. 592,592. (No model.)

To all whom it may concern.-

Be it known that I, EMIL CAPITAINE, a citizen of the German Empire, and a residentof Frankfort-on-the-Main, Germany, have invented and prod uceda new and original Vaporizer and Combustion-Chamber for Petroleum-Motors, of which the following is aspecification, reference being had to the accompanying drawings, forming a part thereof.

IO My invention relates to petroleum-engines; and it consists principally in constructing the combustion chamber with passages in its walls, which passages emanate from a common passage-way within the same into which I5 air and petroleum are respectively delivered through separate inletports, both governed by a single valve, whereby an intimate mixing of petroleum-vapor and of air takes place before the former can come in contact with the cooled surfaces of the power-cylinder and before the charge of vapor and air is delivered into the combustion-chamber.

In the accompanying drawings, illustrating my invention, Figure 1 is a vertical section 2 5 with the discharge-valve, actuating devices shown in elevation, and Fig. 2 is a horizontal section through the lines 1 2 of Fig. 1.

The power-cylinder is indicated at A and is provided with passages a in its walls to en- 0 able it to be cooled in any proper and known manner. 7

B is the power-piston and E the usual valve thereof.

Mounted above the power cylinder and 3 5 opening into the same is the non-cooled combustion-chamber G, the top of which is provided with a discharge-port d, valve d having stem D for discharging the products of combustion, the said valve being actuated by '0 any proper means, such as indicated in the drawings at F. The combustion-chamber at its top is constructed as shown in Fig. 2-that is to say, its walls have two internal passageways 0 c terminating in ports 0 0, opening 5 into the chamber, and these passage-ways o emanate from a single and common passageway c, the entrance to which is governed by a spring-controlled check-valve b,wl1ich likewise and by the same movements controls the inlet-ports b b for admitting the requisite quantity of petroleum-vapor and air, respectively.

The chamber 0, above referred to, is formed in a lateral extension (see Fig. 2) of the combustion-chamber, into which the inlet-ports extend, and the passage-ways c extend out through the walls of this extension.

The general principle of construction and mode of operation other than as stated of this petroleum-motor are the same as in other known gas-engines having four movements of the piston to each revolution.

The operation of the device as improved by my novel construction of the combustionchamber and vaporizer Ois as follows: During the suction-stroke of the power-piston B, following the upstroke, which has discharged the burned products of the previous explosion through the valve-port d and discharge-port d, the spring-controlled valve E will rise and open its port, admitting air, while at the same time the spring-controlled check-valve b Will open the air and petroleum inlet ports b and b admitting the requisite quantity and relativelyproper proportions of air and vapor into the common passage-way or chamber a and thence through the passages c c and ports 0 0' into the vaporizer and combustion-chamber 0, they having been thoroughly and intimately mixed on their passage to the chamber 0, which being a non-cooled chamber causes an expansion of the mixture followed by an explosion produced by the usual means, and hence there is. a consequent return or drive stroke of the power-piston.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

The combination of the power-cylinder, the non-cooled combustion-chamberopening into said power-cylinder, and having its wall or shell formed with a lateral extension, a supplemental chamber formed in said extension, air and vapor inlet ports leading into said supplemental chamber, and internal passages 5 c c emanating from said supplemental chamher and extending through said extension into the wall of the combustion-chamber and terminating in ports which communicate with the upper portion of said combustion-cham- IOO ber, together with a valve seated in said supname to this specification in the presence of plemental chamber and arranged to control two subscribing" witnesses.

communication between the inlet-ports and FMIL CAPITAINE the said passage-Ways, and a spring for con- 5 trolling the movement of said valve, snbstan- XVitnesses:

tially as specified. DEAN MASON, In testimony whereof I have signed my JEAN GRUND.
