Improvements in and connected with Spray-apparatus for
Hydrocarburetted-air Engines.
I, ADOLPH ALTMANN, of 68, Archer Strasse, Berlin, in the German Empire,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improved means for controlling the intermittent supply
of petroleum or other liquid hydrocarbon to motor engines operated by the
combustion of such liquid fuel vaporised in atmospheric air.
Apparatus adapted for carrying my invention into effect is represented in the
accompanying drawings, whereof Fig. 1 is a vertical section and Fig. 2 a plan.
Figs. 3 and 4 are end elevations of parts hereinafter more particularly referred to.
The oil-chamber 1 is mounted upon the receiver 4 and is kept filled to a
fixed height from a reservoir provided with a regulating valve and adapted to
maintain the oil at the desired level. Oil enters the chamber 1 through the pipe 2.
This chamber is provided at the bottom with a valve 3 which regulates
the admission of oil to the reservoir 4. The under side of the reservoir 4 is
formed with a pocket 16 having a drain-cock 17. The reservoir 4 communicates
by the pipe 7, past the explosive-mixture-inlet-valve 8, with the motor-cylinder.
This valve is opened by the arm 9, and held open during the charging stroke
of the engine. When the arm 9 opens the valve 8 by pressing on its spindle,
the valve 3 of the oil-chamber is at the same time opened by means of the
arm 12, which is actuated by the rocking shaft 10 and arm 11. By means of
the adjusting screw 13, the position of the arm 11 may be altered in the direction
of the length of the arin 9; thereby enabling its throw to be varied and the opening
of the oil-valve 3 to be regulated.
The action of the apparatus is as follows:-The cam 18 on the revolving shaft 19
opens the valve 8 by means of the roller. 22, the arm 23, the rod 20 and the arm 21.
The valve 3 at the bottom of the oil-chamber 1 is at the same moment opened,
and oil is permitted to flow past it to the receiver 4. The oil, on entering the
receiver 4, is met by a current of atmospheric air entering through the tube 5, and,
having been converted into spray, is carried past the admission valve 8 to the
motor-cylinder, where it is compressed and ignited and the products of combustion
expelled, during successive strokes of the engine, in the usual manner.
The valve 3 is shut at or about the same moment as the admission valve 8, so as
to prevent oil lodging in the pipe 7, because oil lodged in that pipe would, on the
valve 8 being again opened, obtain access in an unvaporised state to the cylinder.
With the same object, the receiver 4 has a slit 14, opening into the pocket 16,
and provided with a lip 15 on the front side for the purpose of intercepting any
liquid oil which may have remained unabsorbed by the inflowing current of air.
Any such excess may be drawn off by way of the cock 17 and returned to the oil-
reservoir.
The cam 18 is caused to slide to and fro on the shaft 19 by the governor. The
governor may actuate a bell-crank lever, one arm of which engages with a groove
in the sleeve whereof the cam 18 forms part. In its normal working position,
the cam 18 opens the valves 8 and 3 at each revolution of the shaft 19. When,
however, the engine is running too fast, the cam 18 is drawn back out of the path
of the roller 22; the valves 8 and 3 consequently remaining closed until the cam is
Mechanism for
again allowed by the governor to resume its normal position.
moving a cam such as 18 is described in the Specification to Letters Patent No. 7157
granted to me and bearing date 25th April, 1891.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
1. For use with hydrocarburetted-air engines, the combination of mechanism,
substantially as described with reference to the accompanying drawings, for
operating the inflammable-vapour-admission valve and the liquid-hydrocarbon-
controlling valve simultaneously.
2. In mechanism for operating the inflammable-vapour-admission valve and the
liquid-hydrocarbon-controlling valve from the same source of motion, the herein-
described means for rendering the working of the latter valve manually adjustable
without stopping the engine.
3. In a hydrocarbon engine, the combination, with the liquid-hydrocarbon-
controlling valve 3, the air-passage 5, and the passage 7 leading to the admission
valve 8, of the slit 14, the pocket 16, and the lip 15, substantially as and for the
purpose herein set forth.
Dated the 9th day of November 1892.
