Improvements in Apparatus for Distributing Liquid Hydrocarbons
in Motive-power Engines.
A communication from the Firm ADOLPH SAURER, of Arbon, Switzerland.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature
of this invention to be as follows:.
In motive power engines working with liquid hydrocarbons the liquid com-
bustible is often pumped into the engine by means of a special pump, which
receives its motion from the controlling mechanism that operates the air-suction
valve. This construction possesses the disadvantages that the supply of com-
bustible to the engine does not occur at the right moment, and that the period
of operation of the pump during one revolution of the engine is limited to that
of the air-suction valve.
Now, distributing mechanism according to this invention has for object to
obviate these disadvantages by operating the pump and the suction valve by
separate sets of controlling mechanism-each of which can then be made as
desired, of any suitable form for attaining the object in view.
The accompanying drawings represent an example of apparatus according to
this invention.
Fig. 1 is an elevation of the distributing mechanism;
Fig. 2 is a sectional plan thereof;
Fig. 3 is a sectional end elevation corresponding to Fig. 1;
Fig. 4 is a cross-section corresponding to the line A-A of Fig. 2; and
Fig. 5 is a cross-section corresponding to the line B-B of Fig. 2.
1 denotes the controlling shaft from which the suction and exhaust valves, as
well as the pump tor the liquid combustible, receive their motion. The former of
these two valves has its seat in a casing 2, and is acted upon by a double lever 6
which is connected by a rod 7 with a lateral arm 8 on a shaft 11 is mounted
in bearings 10, and is provided with an oppositely extending second arm 12,
which carries at its outer end an abutment 9 against which bear's a second
abutment. The abutment 13 is on the end of a lever 14 whose upper forked
end embraces a roller 15, which bears against a cam 3 mounted on the con-
trolling shaft 1. The axle of the roller 15 is journalled in the forked end of
another lever 16 which is pivoted on a bracket 18 secured to the bracket 17 that
supports the controlling shaft 1.
The exhaust valve, the seat of which is in a casing 19, is acted upon by a
double lever 20, which is mounted on a shaft 21 and carries at its outer end
a roller 23. This roller bears upon the periphery of a cam 4 mounted on the
controlling shaft 1, on which there is also mounted a third cam 5 for actuating
the pump 24. The forked end of a lever 27 pivoted to a bracket 26 carries a
roller 25 which bears upon the periphery of the cam 5, and is embraced by
the forked end of another lever 28, which is furnished at its free end with an

page_text: abutment 29 that bears upon a second abutment 30, located at the end of a
lateral arm 31 of a shaft 46. This shaft has two lateral arms 48 connected at
their outer ends to links 49, which engage at their other ends a cross head 50
on the piston rod of the pump 24.
The shaft 21 has prolongations extending on both sides of the webs 32 of
the bracket which supports it, and the ends of these prolongations carry arms 33
which are connected to the levers 28 and 14 respectively by rods 34. By means
of toothed wheels 36 and 37. the motion of the controlling shaft 1 can be trans-
mitted to a shaft 35 which carries the governor 38. The sleeve of the governor
acts upon a forked lever 39 on the upper end of a vertical shaft 40 that is in
the bracket 26 and carries at its lower end a horizontal arm 41 which is con-
nected to a stirrup-shaped lever 43 by a link 42. The cross piece of this stirrup
lever 43 embracing the lever 20 is provided with an abutment 45 which is
located directly over a stepped projection 44 on the lever 20.
In an engine working with a four stroke cycle the mode of operation of the
controlling mechanism herein before described is as follows:-
The controlling shaft in such an engine makes one revolution while the crank
shaft makes two revolutions and the piston four strokes. In the first stroke
the suction valve is opened by the cani 3 and the mechanism arranged between
the cam and the valve rod, and the pump 24 is also operated during this stroke
by a leading third portion of the projecting part of the cam 5, whereby com-
bustible is forced into the engine. In the two following strokes compression and
ignition of the charge occur in the working cylinder and the further operation
of the pump is effected by the two following third portions of the projecting
part of the controlling cam 5, whereby liquid combustible is drawn into the
pump. The suction period of the pump is therefore twice as long as the pressure
period. In the fourth stroke the exhaust valve is opened by the cam 4 and the
double lever 20, but the pump remains inoperative during this stroke. When
the speed becomes too great the governor comes into action and moves the
lever 43 to the left (Fig. 5), thereby causing the abutment 45 to strike against
the projection 44, and so prevent the lever 20 from carrying out its complete
movement and the exhaust valve from closing. Moreover the lever 20 and with
it the levers 33, the rods 34, and the levers 14 and 28 will take up such a
position for the highest position of the roller 23, that when the levers 14 and 28
are operated by the cams 3 and 5 the abutments 9 and 13, and 29 and 30
respectively, will pass each other, and the suction valve and the pump will
therefore remain inoperative until the governor resumes its former position,
when the abutments 13 and 29 can again engage the abutments 9 and 30 respec-
tively during the upward and downward movement of the levers 14 and 28.

page_text: of this invention and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
-
In motive power engines working with liquid hydrocarbons the liquid com-
bustible is often pumped into the engine by means of a special pump, which
receives its motion from the controlling mechanism that operates the air-suction
valve. This construction possesses the disadvantages that the supply of com-
bustible to the engine does not occur at the right moment, and that the period
of operation of the pump during one revolution of the engine is limited to that
of the air-suction valve.
Now, distributing mechanism according to this invention has for object to
obviate these disadvantages by operating the pump and the suction valve by
separate sets of controlling mechanism, each of which can tuen be made as
desired, of any suitable form for attaining the object in view.
An example of apparatus according to this invention is shown in the drawings
filed with my Provisional Specification.
Fig. 1 is an elevation of the distributing mechanism;
Fig. 2 is a sectional plan thereof;
Fig. 3 is a sectional end elevation corresponding to Fig. 1;
Fig. is a cross-section corresponding to the line AA of rig. 2; and
Fig. 5 is a cross-section corresponding to the line BB of Fig. 2.
1 denotes the controlling shaft (shown in different positions in different
figures) from which the suction and exhaust valves, as well as the pump
for the liquid combustible, receive their motion. The former of these
two valves has its seat in a casing 2, and is acted upon by a two-arm lever 6
which is connected by a rod 7 with a lateral arm 8 on a shaft 11 that is mounted
in bearings 10, and is provided with an oppositely extending second arm 12,
which carries at its outer end an abutment 9 against which bears a second
abutment 13. The abutment 13 is on the end of a lever 14 whose upper forked
end embraces a roller 15, which bears against a cam 3 mounted on the con-
trolling shaft 1. The axle of the roller 15 is journalled in the forked end of
another lever 16 which is pivoted on a bracket 18 secured to the bracket 17 that
supports the controlling shaft 1.
The exhaust valve, the seat of which is in a casing 19, is acted upon by a
two-arm lever 20, which is mounted on a shaft 21 and carries at its outer end
a roller 23. This roller bears upon the periphery of a cam 4 mounted on the
controlling shaft 1, on which there is also mounted a third cam 5 for actuating
the pump 24. The forked end of a lever 27 pivoted to a bracket 26 carries a
roller 25 which bears upon the periphery of the cam 5 and is embraced by
the forked end of another lever 28, which is furnished at its free end with an
abutment 29 that bears upon a second abutment 30, located at the end of a
lateral arm 31 of a shaft 46. This shaft has two lateral arms 48 connected at
their outer ends to links 49, which engage at their other ends with a cross-head 50
on the piston rod of the pump 24.
The shaft 21 has prolongations extending on both sides of the webs 32 of the
bracket which supports it, and to the ends of these prolongations are fixed arms 33
which are connected to the levers 28 and 14 respectively by rods 34. By means
of toothed wheels 36 and 37 the motion of the controlling shaft 1 can be trans-
mitted to a shaft 35 which carries the governor 38. The sleeve of the governor acts
upon a forked lever 39 on the upper end of a vertical shaft 40 that is mounted in
the bracket 26 and carries at its lower end a horizontal arm 41 which is con-
nected to a stirrup-shaped lever 43 by a link 42. The cross piece of this stirrup
lever 43 embracing the lever 20 is provided with an abutment 45 which is
located directly over a stepped projection 44 on the lever 20.
In an engine working with a four stroke cycle the mode of operation of the
controlling mechanism herein before described is as follows:-
The controlling shaft in such an engine makes one revolution while the crank
shaft makes two revolutions and the piston four strokes. In the first stroke

page_text: the suction valve is opened by the cam 3 and the mechanism arranged between
the cam and the valve rod, and the pump 24 is also operated during this stroke
by a leading third portion of the projecting part of the cam 5, whereby com-
Lustible is forced into the engine. In the two following strokes compression and
ignition of the charge occur in the working cylinder and the further operation
of the pump is effected by the following two third portions of the projecting
part of the controlling cam 5, whereby liquid combustible is drawn into the
pump. The suction period of the pump is therefore twice as long as the pressure
period. In the fourth stroke the exhaust valve is opened by the cam 4 and the
two-arm lever 20, but the pump remains inoperative during this stroke. When
the speed becomes too great the governor comes into action and moves the
lever 43 to the left (Fig. 5), thereby causing the abutment 45 to strike against
the projection 44, and so prevent the lever 20 from carrying out its complete
movement and the exhaust valve from closing. Moreover, when the roller 23
is in the highest position attainable by it with the lever 20 stopped by the
abutment 45, the lever 20, and the levers 33, the rods 34, and the levers 14
and 28 are in such a position that when the levers 14 and 28 are operated by
the cams 3 and 5 the abutments 9 and 13, and 29 and 30 respectively, pass
each other, and the suction valve and the pump therefore remain inoperative
until the governor resumes its former position, when the abutments 13 and 29
can again engage the abutments 9 and 30 respectively during the upward and
downward movement of the levers 14 and 28.
