COMPLETE SPECIFICATION.
Improvements in Gas Engines.
I, HUBERT CHARLES BAKER, of No. 30 Main Street, in the City of Hartford and
State of Connecticut, United States of America, Gentleman, 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 appertains particularly to engines of that class in which the
power for driving the piston is derived from the explosion, within an explosion-
chamber in the piston-cylinder, of a suitable explosive-such as a mixture of air
and naphtha, or air and any suitable liquid hydrocarbon; and the invention relates
more specifically to the valve mechanism and accessory devices for producing the
explosive mixture and for supplying said mixture to the explosion-chamber of
piston-cylinder in regulated quantities, proportionate to the work it is desired
the engine shall perform.
One object of my present invention-in addition to that of producing an
improved, compact, and efficient gas-engine as a whole, and one which may be
run at a high rate of speed and develop the maximum amount of power to a given
quantity of gas consumed is to provide, in connection with the explosion-chambers
of a gas-engine cylinder, improved liquid-feeding and gas-distributing mechanism
embodying certain instrumentalities of a novel character and whereby the so-called
explosive charges" may be supplied to the piston-cylinder at definite intervals
and whereby the individual or successive quantities of volatile liquid hydrocarbon
going to make up the successive explosive charges may be arbitrarily increased or
decreased during the operation of the engine, to thereby regulate the explosive
efficiencies of such charges.
A further object of the invention is to provide, in connection with a series of
cylinders and a governor of a gas-engine, a rotary liquid-feed device having a
series of reciprocative feeders or feed-pistons, corresponding in number to the
number of engine-cylinders; and to provide instrumentalities controlled by the
speed of the governor, for independent or successively nullifying the feeding
operation of such feeders when the engine reaches or passes a predetermined speed
limit; also to provide means controlled by the rotation of the feed device, for
periodically imparting inward and cutward strokes to the feed-pistons, to thereby
draw in and expel a predetermined quantity of liquid hydrocarbon at different
points, respectively, in the rotative movement of the feed-valve; and also to
provide means for arbitrarily increasing or decreasing the effective strokes of the
feeders or feed-pistons, to thereby increase or decrease the quantity of liquid fed
at each working stroke of said feeder or piston, as may be required when using
different kinds or grades of liquid hydrocarbon for operating the engine.
In the drawings accompanying and forming part of this specification, Figure 1
is a vertical longitudinal section, partly in elevation, of a gas-engine embodying
my present invention, said section being taken in dotted line a-a, Fig. 2, looking
toward the right hand in said figure. Fig. 2 is a front end view of the engine,

page_text: as seen from the right hand in Fig. 1, some parts thereof being removed and the
other parts thereof being partly broken away. Fig. 3 is a cross-sectional view of
the engine, taken in dotted line b-5, Fig. 1, and looking toward the right hand
in said figure. Fig. 4 is a sectional side elevation of a portion of the engine, as
seen from the right hand in Fig. 2, said figure showing the liquid-feed and gas-
distributing devices partially in section and also showing, in elevation, certain
of the instrumentalities which control the movements of the liquid-
feeders. Fig. 5 is a sectional end elevation, showing certain of the
elements illustrated in Fig. 4, as seen from the right hand in said figure, the
diametrical outline of the engine and a part of the engine-frame being shown in
dotted lines. Figs. 6 and 7 are side and end views, respectively, of the shiftable
cut-off device operable for nullifying the operations, singly and successively, of
the liquid-feeders. Figs. 8, 9, and 10 are sectional side views of certain of the
instrumentalities which control the movements of the liquid-feeders, said figure
showing, respectively, three successively-advanced positions of the cut-off device
or sleeve with relation to the three feeder-actuating levers, Fig. 8 showing the
cut-off device in position for nullifying the operation of one actuating-lever and
the feeder it operates, Fig. 9 showing the cut-off device in position for nullifying
the operation of the two levers and their respective feeders, and Fig. 10 showing
said cut-off device in position for nullifying the operation of the entire set of
levers and their respective feeders. Figs. 11, 12, and 13 are cross-sectional views
of the liquid-feed device, said figures being companion figures to Figs. 8, 9, and 10,
respectively, and showing, respectively, one, two, and three liquid-feeders locked
against operative movement, as will be case when the cut-off device and feeder-
actuating levers are in the positions shown in Figs. 8, 9, and 10, respectively.
Fig. 14 is a cross-sectional view, on a relatively small scale, of a portion of the
engine, taken on a line corresponding with the dotted line d-d, Fig. 1, and
showing the position of the gas-distributing valve or engine-valve when the upper
piston of the series is near the end of its exhausting stroke and in the position it
occupies preparatory to the admission of a charge to the combustion-chamber of
this cylinder, this figure being intended to show the position of the distributing-
valve immediately preceding the admission of an explosive charge to one of the
cylinders, in which position communication between the inlet and exhaust ports
of the valve and the port-passages of the cylinders is cut off. Fig. 14 is the first
of a series of groups of figures illustrating successive positions of the distributing-
valve or engine-valve and the corresponding relative positions of one piston during
one complete rotation of the crank-shaft of the engine, said groups of figures,
collectively, showing one complete reciprocation of the piston, whereby a charge
is drawn into the explosion-chamber and compressed ready to be subsequently
fired. Fig. 15 is a sectional side view of a portion of the engine, said section
being taken on a line corresponding to the dotted line e--e, Fig. 14, and showing a
piston in the dead-stroke position, when the engine-valve is in the position shown
in Fig. 14. Fig. 16 is a cross-sectional view, similar to Fig. 14, showing the
distributing or engine valve advanced sufficiently to bring its induction-port in
communication with the duct of the upper cylinder and the exhaust-port thereof
in communication with the duct of the right-hand cylinder. In this position of
the valve the upper cylinder is drawing in the explosive charge--and the products
of combustion are being exhausted from the lower right-hand cylinder. Fig. 17
is a sectional side view, similar to Fig. 15, showing the relative positions of the
piston when the valve is in the position shown in Fig. 16. Fig. 18 is a cross-
sectional view, similar to Figs. 14 and 16, the engine-valve being advanced
sufficiently to cut off communication between the induction-port of the valve and
the ducts of the engine-cylinder, said valve being shown in the position it occupies
upon the inauguration of the pressing stroke of the piston. Fig. 19 is a sectional
side view, similar to Figs. 15 and 17, showing the upper piston at the forward end
of its dead-stroke, or in the position it occupies when the valve is in the position
shown in Fig. 18. In this position of the piston the explosive charge has been

page_text: drawn into the cylinder ready to be compressed. Fig. 20 is a cross-sectional view,
similar to Figs. 14, 16 and 18, showing the valve advanced sufficiently to bring the
induction-port in communication with the lower right-hand cylinder and its
exhaust-port in communication with the lower left-hand cylinder, communication
between the valve and the upper cylinder being cut off, this being the position of
the valve during the operation of the explosive charge and during the explosion
of said charge. Fig. 21 is a sectional side view, similar to Figs. 15, 17, and 19,
showing the piston in the position it occupies when the valve is in the position
shown in Fig. 20 and just preparatory to the explosion of the compressed charge
contained in this cylinder. "Fig. 22 is a cross-sectional view, on a relatively large
scale, of a portion of the main body of the engine, taken in a line corresponding
with the dotted line f-f, Figs. 1, 3, and 24, said figure showing the means whereby
air is admitted to the valve-chest. Fig. 23 is a plan view, partly in section, of
the liquid-feeding and gas-distributing valve or valves. Fig. 24 is a cross-
sectional view of a portion of the engine, taken on a line corresponding to the
dotted line gy, Fig. 22. Figs. 25 and 26 are cross-sectional views of the
three-way valve which controls the admission of air to the valve-chest. Figs. 27, 28,
and 29 are similar graphical diagrams illustrating, in the order of their
enumeration, three successive explosions of the explosive charges in the three
cylinders and illustrating the relative, alternating order of the explosions in said
three cylinders: this group of figures illustrating one cycle of explosions, alter-
nately, in the successive cylinders during one and one-third of a rotation of the
crank-shaft of the engine.
Similar characters designate like parts in all the figures of the drawings.
For convenience, the improvements or instrumentalities constituting the subject-
matter of my present invention are shown and described in connection with a
gas-engine, which, in many respects, is similar to the gas-engine described in
British Patent No. 15045 dated July 7, 1896, and it is desired to state in this
connection that any suitable liquid hydrocarbon, mixed with air for generating a
highly combustible gas or explosive mixture, may be employed to operate the
engine; and to enable the use of different kinds and qualities of liquid hydrocarbon
without changing the effective operation of the engine, I have provided instru-
mentalities for arbitrarily changing with precision the quantity of liquid
hydrocarbon in the explosive charges, according to the grade, quality, or kind of
liquid hydrocarbon it is desired used, as will be hereinafter fully described.
In the preferred embodiment thereof shown and described, the gas-engine has
three cylinders, which are designated by C1, C2, and C, respectively, and are
equi-distantly disposed about, and in parallelism with, the main or crank shaft D.
it will be understood, however, that any number of cylinders, arranged in any
suitable manner, may be employed within the scopes and limits of this invention,
although in most cases it is preferable to employ three cylinders, as shown in the
drawings; therefore, it is not desired to limit this invention to any particular
number of cylinders or to the particular disposition thereof.
In the present instance the cylinders C, C2, and C3 of the engine are shown
integral with the base of the framework (designated in a general way by F.) This
framework, which may be of any suitable construction for carrying the stationary
and working parts of the engine, which preferably is a one-piece casting, comprises
a suitable bed-plate 3, the front and rear end walls 4 and 5, respectively, and the
main body portion 8 in which the cylinders C, C, and C are formed and in
which the parts of the cylinders are located, as will be understood by reference to
Figs. 1, 2, and 3 of the drawings.
It will be understood that while it is desirable to cast cylinders and framework
together in one piece this construction may be modified without departure from
my present invention.
Located in convenient relation to the three cylinders C', C, and C³ is a
valve-chest E', which is herein shown similar, in a general way, to the valve-chest
designated by the same character in the patent. herein before referred to, said

page_text: valve-chest having a conical valve-seat, the axis of which is shown located in the
vertical plane of and parallel to the main shaft D.
Leading from the valve-chest E are three port-passages c', 2, and 3, which
communicate with the cylinders C, C2, and C³, respectively.
In the preferred form thereof herein shown and described, each cylinder has
on its interior near the rear end thereof a perforated flange f, which practically
divides the cylinder into two communicating chambers-that is, a piston-chamber
and an explosion-chamber-and also affords a convenient means for disseminating
and thoroughly mixing the constituents of the explosive charge before and during
the compression of the charge and preparatory to the ignition and explosion of
said charge, which is a matter of considerable importance in engines of this class,
as it precludes the possibility of an explosion of a charge before its constituents are
thoroughly commingled.
To prevent overheating of the cylinders and valve-chest, a water-space 24 is
formed around said cylinders and valve-chest, after the usual manner of engine
construction, and a constant circulation of water or other suitable fluid may be
maintained in said space in any usual or suitable manner.
**
The main shaft D of the engine, which will, for convenience, be herein termed
the crank-shaft," is shown journalled at its front and rear ends in suitable
bearings 9 and 9' on the front and rear walls 4 and 5 of the engine-frame, as
shown most clearly in Fig. 1 of the drawings. This shaft is shown located in
horizontal parallelism with the axis of and midway between the three
cylinders C, C, and C, respectively, and is provided at its forward end with a
crank 12, which is connected by a universal actuator with the pistons of the
cylinders C, C2, and C, as will be hereinafter described.
The general construction and operation of the piston mechanism-to wit, the
pistons, crank-shaft, crank-shaft actuator, and connections-may be similar to
that of like parts described in British Patent No. 15045%,
The pistons (designated by G1, G2, and 3, respectively,) of the cylinders C¹, C²,
and C, respectively, are each shown tubular and open at the forward end thereof.
The piston-rods (designated by g', g², and g, respectively,) are each shown provided
with balls 26 and 261, one at each end thereof, the ball 26 of which is seated for
universal movement in a ball-socket 25, located upon the interior of the piston
near the middle portion thereof, and the ball 26' of which is seated for universal
movement in a ball-socket 27, formed in the outer end of a radially-disposed arm 28
of the crank-actuator, which actuator is supported and connected to the crank 12
of the crank-shaft D to have a universal oscillatory movement.
As a convenient means for supporting the oscillatory crank-shaft actuator in
operative relation with the three pistons G1, G2, and G³ and to permit a free
universal movement thereof, this actuator is shown comprising two members,
(designated in a general way by H and K, respectively,) one of which members,
as K, is pivotally supported, as at 32 and 321, in suitable bearings on the frame of
the engine with its axis in a horizontal plane at right angles to, and in alinement
with, the axis of the main shaft D, and the other of which members, as H, is
pivotally supported on the member K with its axis of movement at right angles,
or substantially so, to the axis of movement of said member K, the construction
and organization of this actuator being shown substantially the same as the con-
struction and organization of the actuator described in British Patent No. 15045%,
the member H being pivotally connected at its inner end to the crank 12 of the
main shaft 1 of the engine, which crank is counterweighted for obvious reasons.
As a convenient and novel means for periodically feeding successive, definite
quantities of liquid hydrocarbon to a mixing conduit or chamber and mixing the
same with air to produce explosive charges of requisite efficiencies and for dis-
tributing said explosive charges to the several cylinders in proper order, and
as a means for arbitrarily regulating the feed, independent of the operation of
the engine-governor and irrespective of the speed of the engine, I have provided
in operative relation with the port-passage of the several cylinders a so-called

page_text: "liquid-feeding" and "gas-distributing" apparatus, which, in addition to the
actuating and controlling mechanism therefor, comprises, practically, two.
independent devices-to wit, a rotative feed device embodying preferably series"
of independently-operable reciprocatory feeders, which are adjustable for regulat-
ing the quantity of the liquid fed, and a gas-distributing device in operative
connection with the feed device and adapted for controlling the introduction of
the explosive charges to the several cylinders.
"
In the preferred form thereof shown in the drawings the liquid-feed device and
gas-distributing device are in the nature of a unitary apparatus and may be
hereinafter referred to, collectively, as the "feeding and distributing apparatus
or feeding and distributing valve" and independently, as the "liquid-feed
device" and "gas-distributing device," respectively.
It will be obvious, however, that the construction and general organization of
the feed device and distributing device might be variously modified without
departure from this invention.
The feeding and distributing apparatus, in the preferred form thereof shown in
the drawings, comprises a rotative axially-recessed member, (designated in a
general way by E,) which is shown in the nature of a plug-valve situated in a
valve-chest E, having an axially-bored stem 20, which is journalled in suitable
bearings on the framework of the engine, said valve also having an inlet-port 15
and an exhaust-port 16 in position for periodically communicating, in alternating
order, with the port-passages e, 2, and 3 of the piston-cylinders C, C, and C³,
during the rotation of said valve member; one or more (herein shown as three)
liquid-feeders or feed-pistons, (designated in a general way by el, c², and e³,
respectively,) carried by said valve member; a liquid-duct P2, having its discharge
end in communication with a reservoir or liquid-chamber 40, which is shown as a
depression formed in the inner face of the valve-chest in juxtaposition to the path
of movement to the liquid-feeders and which constitutes a reservoir for supplying
liquid to the pockets in which the feed-pistons work during the operation of the
engine and for holding a surplus of liquid over and above that required for one
charge; means for actuating the valve member; means for controlling the
movements of the liquid-feeders; and means for supplying air to the valve-chest,
all of which will be hereinafter more fully described.
In the preferred form thereof herein shown the liquid-feeders el, e, and e³ are
in the nature of piston-valves. seated for reciprocatory movement in radially-
disposed pockets f, f, and f³, formed in the valve member E, said pockets
extending from the periphery of the valve member to, and communicating with,
the axial opening in said member, as will be understood by reference to Figs. 1
and 5 of the drawings, said pockets being located near the outer end of the valve
member in position to communicate with an oil-reservoir and a mixing passage,
alternately. This oil-reservoir is shown as a depression 40, formed in the upper
face of the inner face of the valve-chest between said valve-chest and the valve
member E and in juxtaposition to the path of movement of the oil-feeders c¹, e,
and e.
As a means for actuating the valve member E, direct from the crank-shaft D,
to thereby establish communication between the inlet and exhaust ports 15 and 16,
respectively, with the port-passages of the piston-cylinders at the requisite time
and in the order required, the crank-shaft D is furnished with a driving-pinion 17,
which meshes with a driven pinion 18, fixed to the valve-stem 20, the relative
size and arrangement of the two pinions being such that the valve will make one
complete rotation during two complete rotations of the crank-shaft D and in an
opposite direction.
As a means for holding the valve member E to its seat, I have provided a
resilient abutment at the outer end of the valve-stem, which, in the form shown,
is in the nature of a spring 22, carried upon a sleeve 23, secured to the framework
in axial alinement with the valve-stem, which spring is shown located between
suitable washers 23¹ and 2311, one of which bears against the end of the valve-stem

page_text: and the other of which bears against a flange on said sleeve; other means, however,
may be provided for effecting this end without departure from my present invention.
In the preferred form thereof herein shown, the valve E, which, as before
stated, is in the nature of a rotary plug-valve, is shown peripherally grooved, as
a: 13, to form a circular gas-conduit or passage-way for conducting the explosive
mixture from the mixing-chamber of the valve-chest to the inlet-port of said
valve. The inlet-port 15 of the valve-chest, which is formed longitudinally in
the periphery of the valve member E, is open at one end to the circular gas-
conduit 13, as shown most clearly in Fig. 23; and the exhaust-port 16, which is
open at one end of the periphery of the valve member E, has its outlet end
preferably coincident with the axis of the valve member and is open at this end
to an exhaust-chamber 14, located in the valve-chest in advance of the inner end
ot the valve member, as shown most clearly in Figs. 1 and 22.
As a convenient means for obviating the obnoxious noises incident to the
exhaust in most engines of this class, I have provided, in connection with the
exhaust-chamber 14 of the engine, a so-called muffler-box," (designated in a
general way by M,) having a series of communicating compartments (herein shown
as two compartments) 90 and 90', separated from each other by an exhaust
deflector or partition 92. One of said compartments, as 90, is shown communicat-
ing with the exhaust-chamber 14 of the valve-chest, and the other of said
compartments, as 90', is shown having an exhaust-conduit 93, leading to the outer
This
atmosphere, as shown most clearly in Figs. 1 and 22 of the drawings.
deflecting partition will, in practice, be of such construction as to cause the exhaust
to traverse the entire length of the receiving-compartment 90 before being admitted
to the exhaust-compartment 90'. The construction and organization of the parts
of the muffler-box may be variously modified without departure from this invention.
In engines of this class it is frequently highly advantageous in producing the
gaseous explosive mixture to heat the air to a comparatively high degree before
mixing the liquid hydrocarbon therewith; and as a convenient means for supplying
hot air to the mixing-chamber of the valve-chest the muffler-box is furnished
with a hot-air compartment 94, which surrounds the inlet and exhaust compart-
ments 90 and 90', by a partition 95, which constitutes the outside walls of the
muffler-box proper separating the compartments 90 and 90' from the compart-
ment 94. This hot-air compartment 94 is shown having an inlet 94' near the
exhaust end of the muffler-box at one side of the partition 95 and has an outlet
end near the opposite end of the muffler-box, as shown most clearly in Fig. 22, said
outlet communicating with the mixing-chamber or main air-passage 131, which
is located near the lower part of the valve-chest and intersects the path of
1-ovement of the liquid-feeders e', &, and e³, said air-passage extending horizontally
to the opposite side of the valve member and having a branch 13, which com-
municates with the circular passage-way 13 in the valve member E, as will be
readily understood by comparison of Figs. 1, 4, 22, and 24 of the drawings.
As a means for supplying air to the hot-air compartment 94, a pipe or conduit 96
leads from the inlet-opening 94' of said compartment to the interior of the engine-
case, as shown at 94, air being supplied to the interior of the engine-case through
a screen 97 at one end of said case, as shown most clearly in Fig. 1.
As a convenient means for supplying moderately cool air to the mixing-chamber
of the valve-chest E' direct from the interior of the engine-case, I have provided,
i.. connection with the main air-passage 131 of the valve-chest and conduit 96,
which leads from the interior of the engine-case to the hot-air compartment of
the muffler-box, an air-supply pipe 98; and as a convenient means for cutting out
one or the other supply-conduits 96 or 98, so that air may be supplied direct
from the interior of the engine-case to the mixing-chamber of the valve-chest, or
may be supplied to said mixing-chamber from the interior of the engine-case
through the hot air compartment 94; or may be partially supplied to the mixing-
chamber 13, both from the engine-case direct and through the hot-air
compartment 94, I have provided at the juncture of the two conduits 96 and 98 a

page_text: three-way valve, (designated in a general way by B.) which is shown rotatably
supported in a suitable valve-case and has ports adapted for communicating with
the conduits 96 and 98 and with the interior of the engine-case, as will be readily
understood by a comparison of Figs. 3, 22, 25, and 26 of the rawings, the ports
of the valve being so disposed that the conduit 98, which leads to the mixing-
chamber 13 direct from the valve, may be cut off, as shown in Fig. 22, thus
insuring the delivery of hot air from the hot-air compartment 94 to the
mixing-chamber 131; or the hot-air compartment 94 may be cut off, as shown in
Fi. 25, thus supplying moderately cool air from the engine-case direct to the
mixing-chamber 131; or both conduits 96 and 98 may be partially cut off, as
shown in Fig. 26, thus supplying a mixture of moderately cool and hot air to said
mixing-chamber.
The provision of some suitable means--as, for instance, means such as described-
for regulating the temperature of the air before mixing the same with the liquid
hydrocarbon to produce the explosive charge, is of material importance in engines
of the class specified; as air may be artificially heated by the heated products of
combustion, or the residuum of the explosive charges of the engine may be
conducted to the mixing-chamber of the valve-chest when the engine is running
in an intensely cold atmosphere, thereby obviating the injurious cooling of the
air-supply, which would otherwise accrue from the low temperature of the
engine-case or other extraneous causes.
As a means for automatically reciprocating the liquid-feeders or feed-
pistons e¹, e, and e³, to cause them to first draw in and then expel liquid hydrocarbon
at different predetermined points, respectively, in the rotative movement of the
feeder-carrier or valve member E, I have provided, in connection with said feed-
pistons, oscillatory actuators, (designated by k, l, and 3) each of which is shown
in the nature of a lever pivoted at 50, substantially midway of the ends between
the adjacent walls of a groove 50', formed longitudinally in the periphery of the
valve-stem 20, with which said lever rotates about the axis of the valve member E.
These actuating-levers have their inner ends shiftably seated in transverse slots
or grooves 50 in the feed-pistons and are oscillated to effect a reciprocatory
movement of the feed-pistons, preferably through the medium of the cam-face 52
of a shiftable sleeve or cut-off device 0, which surrounds the outer ends of said
actuating-levers, these outer ends of the actuating-levers being normally held in
contact with the cam-face 52 of the cut-off device or sleeve, preferably by means
of springs 53, bearing against the under faces of the outer ends of said actuating-
levers, as shown most clearly in Figs. 1 and 4 of the drawings. This cut-off
device is held as against rotative movement with relation to the valve member E
and the cam-face 52 thereof, which effects the working stroke of the feed-pistons
and is so constructed and so disposed with relation to the reservoir 40 and the
mixing-chamber 131 of the valve-chest, that an inward movement of each
feed-piston will be effected at that point in the rotative movement.of the valve
member when said piston is in juxtaposition to the reservoir 40, and an outward
revement of said feed-piston will be effected when the piston arrives in
juxtaposition to the mixing-chamber 131.
By constructing the feed-pistons to have a reciprocatory movement, as described,
and providing means for reciprocating said pistons automatically, it will be seen
that each inward stroke of a pin will forcibly draw in a charge of liquid when
said feed-piston arrives opposite the liquid-reservoir 40, and will forcibly expel
this charge when said piston arrives opposite the mixing-chamber of the valve-
chest, which is an improvement of material advantage over liquid-feeding devices
of ordinary construction wherein liquid is fed to the mixing-chamber by its own
gravity through a regulated opening, as it insures the feeding of the charges in
predetermined and absolutely precise quantities.
In engines of the class specified, as heretofore made, considerable difficulty has
been experienced from the non-provision of means operable for arbitrarily regu-
lating the quantity of the liquid charges and for arbitrarily also automatically

page_text: reducing or increasing the number of liquid charges admitted to the entire cylinder
or cylinders in a given length of time; and it is one of the chief objects of my present
invention, in connection with the liquid-feeders, whereby the working strokes of
the liquid-feeders may be arbitrarily increased or decreased, so as to increase or
decrease the quantities of liquid fed at cach reciprocation of a feeder and also to
provide independent devices or instrumentalities, one of which is automatically
controlled by the governor of the engine and the other of which is independently
and arbitrarily operable for nullifying the effective operation of the liquid-feeders,
independently and successively, as will be hereinafter more fully described.
For the purpose of arbitrarily regulating the working strokes of the feed-
pistons e, e, and e³, which, as before stated, are radially disposed with respect
to the axis of the valve member E, I have provided a feed-stroke limiter, which,
in the form thereof herein shown, is in the nature of a rod 55, shiftably supported
in the axial bore or recess of the valve-stem 20 and has a conical working end,
the axis of which intersects at right angles to the radial axis of movement of the
feed-pistons, the working end of said feed-stroke limiter acting as a wedge-abut-
ment for the ends of the feed-pistons and will, when in position between adjacent
ends of the feed-pistons, limit the inward strokes of said feed-pistons. This feed-
stroke limiter is shown connected at its outer end to the free end of the depending
crank-arm 56, carried on a rock-shaft 57, which is journaled in suitable bearings
in the engine-frame; and as a means for actuating this rock-shaft to shift the
feed-stroke limiter with relation to the feed-pistons, said rock-shaft is shown
furnished near its outer end with an upwardly-extended crank-arm 58, which is
connected by means of a connecting-rod 581 to the crank-arm 59, fixed to the hub
of a bevel-gear wheel 60, carried on a shaft 61, journaled in the engine-frame in
advance of and above the rock-shaft 57, which gear 60 meshes with a gear 601,
journaled in an arm 62 of a bracket Y on the frame of the engine, and which
gear 60 is splined to the longitudinal shiftable shaft 63, which is provided at its
upper end with a hand-wheel 63', by means of which said shaft may be turned to
rotate the gears and through the medium of the connections described, shift the
feed-stroke limiter longitudinally inward or outward, as desired, with relation
to the feeders. This operating-shaft 65 may, as shown, he provided near its upper
end with a pointer 64, co-operating with an indicating-dial 65 for indicating the
position of the feed-stroke limiter and the quantity of the liquid fed at each
working stroke of a feed-piston.
It is desired to state, in the above connection, that the means for operating the
feed-stroke limiter may be materially modified without departure from this
invention.
For the purpose of automatically or arbitrarily nullifying the effective opera-
tions of the feed-pistons, the cut-off device 0, which co-operates with the feed-
piston-actuating levers, and, which, as before stated, is in the nature of a sleeve
shiftably supported for movement longitudinally upon a valve-stem 20 and longi-
tudinally of the feed-piston actuators, has an internal offset or reducing portion 521
ady ted for overriding the outer free ends of said actuators and to shift said ends
inward sufficiently to lock the feed-pistons in their extreme outward or ineffective
positions.
It will be observed by reference to Figs. 8 to 13, inclusive, that when the cut-
off device or sleeve is in the position shown in Fig. 8, the internal offset portion
engages one of the feed-piston-actuating levers, as ¹, which locks said lever against
movement and holds the feed-piston el, actuated by said lever, in the extreme
outward ineffective position shown in Fig. 11. When said cut-off device is
advanced to the position shown in Fig. 9, the levers and will be locked against
movement, and the effective operations of the feed-pistons e and will be
nullified and when the cut-off device is further advanced to the position shown in
Lig. 10, the entire set of the feed-levers 1, 2, and 3 will be locked against
movement, and the effective operations of all of the feed-pistons will be nullified.
As a means for shifting the cut-off device or sleeve O, to successively nullify

page_text: the operations of the different liquid-feeders, I have provided, in connection with
the crank-shaft D, a shifting member, which is shown in the nature of a sleeve 70,
having a depending arm 70, which preferably has a yielding connection with the
cut-off sleeve O, said arm being shown shiftably engaging a pin 71, fixed to
ears 72 and 72, a spiral-spring being interposed between one of said ears and the
arm 70 and being adapted for cushioning the thrust of said arm in case the sleeve
meets with an obstruction during its engagement. This shifting member is shown
normally held in interlocking engagement with another shiftable member 73,
supported upon the crank-shaft 1), and which member is operatively connected
with, and is adapted to be operated by, the governor (designated in a general way
by R.) This governor R may be of any suitable construction and be connected
to the shiftable member 73 in any suitable manner for moving said member longi-
tudinally of the crank-shaft, during variations in the speed of the governor, to
thereby actuate the shifting member 70 and nullify, through the medium of the
cut-off device, the operation of one or more liquid-feeders, as will be understood by
comparison of Figs. 1 and 4 and 6 to 13, inclusive, of the drawings.
It will, therefore, be seen that the cut-off device may be automatically actuated
by the governor of the engine to stop the effective operation of one or more liquid-
feeders; and that the construction and organization of the governor and the con-
nections between the cut-off device and the governor will be such that when the
engine reaches a predetermined speed limit, said governor will immediately act to
nullify the operation of one, two, or all of the liquid-feeders, according to the
excess of speed over and above the normal speed limit of the engine.
As a means for arbitrarily stopping the effective feed operation of, and for lock-
ing, one or more liquid-feeders in an ineffective position, I have provided, in con-
nection with the shifting member 70, hand-operable instrumentalities, which, in
the preferred form thereof herein shown, consists of a sleeve 75, fixed to the opera-
ting-shaft 63, which constitutes the primary actuator for the feed-stroke limiter 55,
which sleeve is shown splined in a bearing on the arm 621 of the bracket Y and is
provided at the lower end thereof with a lateral projecting arm 75', to which is
pivoted a pitman 76, which, in turn, is pivoted at its lower end to an arm 77' upon
a rocking sleeve 77, journaled upon the shaft 61, which sleeve has a downwardly-
projecting crank-arm 77", to which is pivoted an operating-rod 78, the opposite
end of which extends through an opening in a flange 70 on the shifting mem-
ber 70, and is furnished with a head 79, which normally abuts against the inner
face of said flange when the operating-shaft 63 is elevated to shift the cut-off
device to the position shown in Figs. 4 and 8 of the drawings.
By the construction and organization of the cut-off device-actuating instrumen-
talities herein shown and described, it will be seen that the governor of the engine
may operate to shift the cut-off device to the position shown in Fig. 1 without
interfering with the position of the hand-operated instrumentalities which are
operable for effecting the same end; that the hand-operated instrumentalities may
have a movement entirely independent of the movement of the governor, so that
the hand-operated instrumentalities may be set to stop the effective operation of
one or more liquid-feeders-as when it is desirable to reduce the normal speed of
the engine; and that the governor will be effective for stopping the operation of
the remaining operative liquid-feeder when the engine has reached this pre-selected
speed limit, which is a matter of considerable importance in engines of this class,
as it permits a change to be made in the normal speed limit of the engine, arbi-
trarily, and at the same time renders the engine-governor operable for stopping
the engine when the speed limit is reached or passed.
When it is desired to increase or decrease the working stroke of the feed-pistons
to increase or decrease the quantity of liquid in each explosive charge, as is
required when using different kinds of liquid hydrocarbon, it is simply necessary
to impart a rotative movement, in one or the other direction, to the hand-wheel 631
of the operating-shaft 63; and when it is desired to arbitrarily nullify the effec-
tive operation of one or more feeders it is simply necessary to lift the operating-

page_text: shaft 63, which will carry the sleeve 75 upward with it and shift the cut-off device,
as will be readily understood by reference to Figs. 4 and 5 of the drawings, the
shaft 63, constituting a rotatable actuator for operating the feed-stroke limiter
and the sleeve which is carried by the shaft, but which is held as against rotative
movement, constituting a reciprocatory actuator for operating the cut off device.
This reciprocatory actuator is settable at three different positions; and as a
means for automatically engaging and locking the sleeve in one or the other of
its positions, I have provided a spring-actuated detent 85, which is secured to the
interior of the bearing in which the sleeve is seated and constitutes a feather which
extends into the keyway 951 of the sleeve and locks said sleeve against rotative
movement relatively to its bearing, this detent being in the nature of a spring
having a V-shaped head at its free end which normally engages in one or the other
of the notches 96, formed in the keyway of said sleeve, as shown most clearly in
Figs. 4 and 5 of the drawings.
As a convenient means for igniting the explosive charge in the explosion-
chambers of the cylinders, I have provided, in connection with each cylinder, a
spark-producer controlled by the retractive movement of the piston of said cylin-
der. This spark-producer, which may be herein termed the "igniter," consists,
in the preferred form thereof herein shown, of two spark-producing members w
and w, one of which, as w, extends through an insulating bearing secured to the
exploding end of the piston in position for engaging the member w at the end of
the retracting stroke of the piston. The member is shown having a bifurcated
inner end, the prongs of which will preferably be resilient and will be bent to form
wipers for engaging the headed end of the member we, as will be readily under-
stood by reference to Fig. 1 of the drawings. These members constitute the con-
tact-points or electrical terminals of a suitable source of electrical supply-such as
a battery represented in Fig. 1 and designated by W. The member w has its ter-
minal so constructed that the headed end of the member we will engage between
and have a rubbing contact with said terminals just before it reaches the end of
its pressing stroke, to thereby produce a spark, said headed end of the member w¹
being released by the spring terminals of the member when the piston arrives
at the end of its retractive stroke.
Inasmuch as the general operation of the several pistons of the engine and the
valve member E is the same as that described in British Patent No. 150459 herein-
before referred to, and inasmuch as the drawings and descriptions thereof are
sufficiently full and concise as to facilitate an understanding of the relative
operations of the pistons by any one skilled in the art, it is deemed unnecessary in
my present application to enter into a detailed description of the general operation
of the engine.
During the operation of the engine the liquid hydrocarbon is admitted through
the supply-pipe P2 into the reservoir 40 where it passes to the liquid-feeders e¹, e²,
and and is carried around by the valve member E and deposited, charge by
charge, at regular intervals into the mixing-chamber 131 where it is mixed with
the air introduced through the hot-air or cool-air conduits, as hereinbefore
described, whence it is conducted to the circular passage of the valve member E
and is distributed by the induction-port 15 of said member to the successive cylin
ders, alternately and at regular intervals, during the rotation of the valve mem-
ber E, where it is exploded at each compression movement of each piston through
the medium of the spark-producing members w and w¹, which affects an impulse
of the piston of said cylinders, thereby rotating the crank-shaft D; one explosion
taking place at every two-thirds of a rotation of the crank-shaft, which will be
more fully understood by reference to the diagrammatic Figs. 27, 28, and 29 of
the drawings, which figures represent, respectively, by dotted lines 1, 2, and 3,
three successive positions of the crank 12 during three successive explosions,
and which figures represent, respectively, by cross-section circles, the alternating
order in which the explosions take place.

page_text: By a comparison of Figs. 14 to 21, inclusive, and 27, 28, and 29, it will be seen
that in one cycle of operations and correspondingly in the successive cycles of
operations the gas is first drawn in and then compressed and then exploded in
each cylinder, and that these operations take place alternately with respect to
similar operations in other cylinders-that is to say, when the gas is being
exploded in the cylinder C, the products of combustion are being exhausted from
cylinder C³, and gas is being drawn into cylinder C3; next, cylinder C¹ is being
exhausted, the gas in cylinder C2 is being exploded, and the gas in cylinder C³
is being compressed; next, the gas is being drawn into cylinder C, is being com-
pressed in cylinder C2, and is being exploded in cylinder C; and next, gas is being
compressed in cylinder C¹, is being fired in cylinder C³, and the products of com-
bustion are being exhausted from cylinder C. From this description of the alter-
nating order of operation of the successive pistons in the cylinders, it will be appar-
ent that the work is uniformly distributed, and that the engine is well-balanced
and will run with uniformity and with little vibration.
The working parts of the engine will be lubricated in any suitable and usual
manner.
