Improvements in Gas and Oil Engines.
We FREDERIC WILLIAM THOMPSON, of Carr Field, Luddenden, near Halifax,
in the County of York Engineer, ALFRED YATES of Carr Terrace, Luddenden
aforesaid, Engineer, JOSEPH PICKLES BINNS, Engineer of 75 High Street,
Luddenden, aforesaid, late of 38, Cavendish Terrace, West Hill Park Halifax
Yorkshire, and HENRY GREENWOOD BINNS Draughtsman of Thorpe Terrace,
Luddenden, aforesaid, late of 30, Milton Terrace West Hill Park Halifax
Yorkshire, do hereby declare the nature of this invention to be as follows :-
Firstly. We employ what we call a jackall governor, which moves on two
center points, when the speed of the engine is too high.
The said governor is very similar to the pendulum governor.
It is so constructed that the thrust of opening the valve does not come against
the said center points, but a seperate piece is attached to the said governor capable
of being moved backwards and forwards to take the thrust when opening the valve.
When the said piece is released a spring brings it into its former position so that
the said governor can move freely.
Secondly. The use of a chamber for the exhaust mixture surrounded by water
(or water jacketed) placed in the circuit between the cylinder jacket and
water tank (or ciston) thereby keeping the water in the engine jacket more
uniform thereby giving higher efficiency to the engine.

Improvements in Gas and Oil Engines.
We, FREDERIC WILLIAM THOMPSON, of Carr Field, Luddenden, near Halifax,
in the County of York, Engineer, ALFRED YATES, of Carr Terrace, Luddenden,
aforesaid, Engineer, JOSEPH PICKLES BINNS, of 75, High Street, Luddenden,
aforesaid, Engineer late of 38 Cavendish Terrace, West Hill Park, Halifax York-
shire and HENRY GREENWOOD BINNS, of Thorpe Terrace, Luddenden, aforesaid,
Draughtsman, late of 30 Milton Terrace West Hill Park, Halifax, Yorkshire
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:―
Firstly. We employ what we call a jackall governor which moves on two centre
points when the speed of the engine is too high. The said governor is very similar
to the pendulum governor.
It is so constructed that the thrust of opening the valve does not come against
the said centre points, but a separate piece is attached to the said governor capable
of being moved backwards and forwards to take the thrust when opening the valve.
When the said piece is released a spring brings it into its former position, so that
the governor can move freely.

page_text: In order that the first part of our invention may be more clearly understood we
will make reference to the accompanying sheets of drawings, wherein Fig. 1 is
front elevation of our improved self-acting valve-governor and Fig. 2 is plan view
of same. A represents one end of the engine cylinder and B the spindle of the
inlet valve for the admission of combustible mixture. C represents a horizontal
rod having a continuously backward and forward motion imparted to it from an
eccentric or tappet operated from some convenient part of the engine.
"
"
A forked block D is screwed onto the free end of the reciprocating rod C and
within the fork D is another block E made with an upright arm F to which
is fixed a governor G secured to said upright by set screw H. This block E
is held in position by " centres on the ends of set screws I upon which
"
centres the block together with the parts attached thereto are free to oscillate.
The block E is made hollow and receives a piston J, see sectional elevation 3
and sectional plan view 4. This piston J is made with a central opening in
which is inserted a spiral spring K such spiral spring being confined therein
between the central stud L and plate M which is held in position by set screw N.
Therefore when the engine is running at its normal speed the reciprocating rod C
causes the point of the plate M to strike the stud O carried at one end of the
lever P, the opposite end of such lever entering into a socket formed in the head Q
of the valve spindle B consequently at each forward movement of the rod C the
valve is opened for the admission of combustible mixture, but if the speed of the
engine is excessive, the motion of the reciprocating rod C will be quickened causing
the block E to oscillate upon its centres and occupy the position shewn in dotted
lines in Fig. 1, consequently the point of the plate M will be raised above the stud O
whereby the inlet valve would remain closed until the speed of the engine had
become normal again when the block E would oscillate back upon its centres
and return to its normal position when the valve would be opened again for
the admission of the gases.
It will be obvious that each time the point of the plate M strikes the stud O that
the spiral spring K will yield, thus moving piston J and taking the thrust off
the centres or pivots I consequently the wear and tear on the points of the
pivots is very little, thus the block and the governor remain exceedingly sensitive,
this being regulated by setting and adjusting the governor G.
Secondly. The use of a chamber for the exhaust surrounded by water (or
water jacketed) placed in the circuit between the cylinder jacket and the water
tank (or cistern) thereby keeping the water in the engine jacket more uniform,
thereby giving higher efficiency to the engine. This part of our invention is
shewn in Fig. 5 where A is the cylinder of an oil or gas engine and B the outer
jacket. The spent or exhaust gases pass through pipe C into the chamber D where
they escape finally through pipe E. Around the chamber D we place a jacket F
supplied with water which is in communication with the "circuit" of water
between the water cylinder G and the water space H around the engine cylinder,
therefore on the spent gases entering the exhaust chamber D the water in the
jacket F becomes heated before it enters the jacket H surrounding the engine
cylinder.
By this means the temperature of the water in the jacket of the engine cylinder
is more uniform, thereby giving higher efficiency to the engine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
Firstly. A pivoted governor in combination with piston J and spring K
constructed and arranged and operating in the manner herein shewn and for
purposes described.
Secondly. In a gas or oil engine the use therein of a pivoted governor and
yielding piston arranged and operated as described and shewn in Figs. 1 and 2.

page_text: Thirdly. In gas and oil engines the combination therewith of a water jacket
such as F placed in connection with the water circuit all as shewn and described
herein.
