PROVISIONAL SPECIFICATION.
Improved Mixing Valve for Petroleum and other Motors.
JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention which has been com-
municated to me by Moritz Hille of 22 Chemnitzerstrasse, Dresden in the Kingdom
of Saxony, German Empire Engineer to be as follows:-
The present invention consists of a mixing valve by means of which air may be
mixed with fluid petroleum or hydrocarbons.
The apparatus stands in communication with the working cylinder of a motor
through the medium of a vaporising device, forming however no part of the present
invention.
The device consists in a spring pressed air valve closing onto a seat situated
above it and raised by the action of the piston during the suction period of the
motor. This air valve is rigidly connected by means of rods to a second spring
pressed valve situated below it in the valve casing and closing onto a seat in a
bridge piece running transversely through said casing. Through the said bridge
piece is a channel for the entrance of petroleum or liquid hydrocarbon, and
mounted so as to project into said channel is a needle whereby the quantity of
petroleum or hydrocarbon which is to enter the air valve at each stroke of the
latter, may be regulated previous to its reaching the petroleum inlet valve. The
needle valve is provided with a screw spindle and a dial and pointer so that its
position may be regulated from the outside. On actuating the air valve the
petroleum valve will be raised simultaneously whilst both valves return to their
seatings under the action of their springs as soon as the suction of the piston
ceases.

COMPLETE SPECIFICATION.
Improved Mixing Valve for Petroleum and other Motors.
I, JAMES YATE JOHNSON, 47, Lincoln's Inn Fields, London, do hereby declare
the nature of this invention (a communication to me from abroad, by Moritz
Hille of Dresden, Germany) and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
The present invention consists of a mixing valve by means of which air may be
mixed with fluid petroleum or hydrocarbons.
The apparatus stands in communication with the working cylinder of a motor
through the medium of a vaporising device, forming however no part of the
present invention.
The device consists in a spring pressed air valve closing onto a seat situated
above it and raised by the action of the piston during the suction period of the
motor. This air valve is rigidly connected by means of rods to a second spring
pressed valve situated below it in the valve casing and closing onto a seat in a
bridge piece running transversely through said casing. Through the said bridge
piece is a channel for the entrance of petroleum or liquid hydrocarbon, and
mounted so as to project into said channel is a needle valve whereby the quantity
of petroleum or hydrocarbon which is to enter the air valve at each stroke of the
latter, may be regulated previous to its reaching the petroleum inlet valve. The

provided with a screw spindle and a dial and pointer so that its
position may be regulated from the outside. On actuating the air valve the
petroleum valve will be raised simultaneously whilst both valves return to their
seatings under the action of their springs as soon as the suction of the piston
ceases.
In order to make this invention more easily intelligible reference is had to the
accompanying drawings in which similar letters denote similar parts throughout
the several views.
Fig. 1 is a vertical section through the apparatus or valve.
Fig. 2 is a section on line ar Fig. 1 and
Fig. 3 is a front view of a pointer and disk by means of which the quantity of oil
or hydrocarbon passed may be regulated.
In the upper part of the casing a is mounted the air inlet valve a having
spindle a and spring a to press against a plate at at the top of the said spindle and
normally hold the valve a up on its seat.
The said valve a is however connected, by rods c c to a spring actuated valve d
adapted close or open an inlet passage g for the oil or hydrocarbon, said passage
being regulated by means of a needle valve 3 having on its spindle a thread f.to
fit an interior thread in the valve casing and being held tight by a gland 2. By
means of the valve f³ and the pointer and dial the quantity of oil or hydro-
carbon passed by the valve may be varied in proportion to the amount of air
let in.
During the suction period of the motor, the valve a will be opened and will
admit air into the chamber ; at the same time the valve d will be opened and
petroleum or hydrocarbon admitted at e forming an explosive mixture in the said
chamber which then passes to the vaporising chamber and thence to the cylinder,
where it is ignited.
For the purpose to cause the air to enter into chamber in advance of the oil,
the rods c c are provided with nuts c¹ so arranged that they do not press upon the
traverse to move down the valve d until the air inlet valve a has been opened,
whereafter the rods c, c by means of such nuts push against the ends of the
traverse and cause the oil inlet to be opened.
The rods c, c will therefore be out of operation for the time the air inlet valve
moves down until the nuts reach the traverse i.e. the time for the entrance of air
alone into the chamber 6 will be proportionate to the distance from the traverse the
nuts have been adjusted on the rods.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. An apparatus for producing a mixture of air and petroleum or liquid hydro-
carbon, consisting in the combination of an air inlet valve a having spindle a² and
spring a³, to normally keep it closed on its seat, said valve opening into a chamber b,
a spring pressed oil valve d also opening into the chamber 6 and rods cc connecting
the valves a and d substantially as described.
2. An apparatus for producing a mixture of air and petroleum or liquid hydro-
carbon, consisting in the combination of an air inlet valve a having spindle a² and
spring a, to normally keep it closed on its seat, said valve opening into a chamber b,
a spring pressed oil valve d also opening into the chamber band rods cc connecting
the valves a and d and valves having screw spindle and pointer to regulate the oil
inlet at g substantially as described.
