Improvements in and relating to Gas Engines.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 322, High Holborn, in the county of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil 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:-
My invention relates to improvements in gas engines. The mechanism of this
invention is constructed as follows. A governor-ball-regulator A of great sensitive-
ness imparts itself an up and down movement to the angle lever B, the axis of revelu-
tion of which is fixed upon a pillar C.
The left arm of the lever is forked and supports two guiding rollers, which move
in the sliding ring of the regulator. The right arm of the lever is pivotally con-
nected with the rod D, which in turn is pivotally connected with a sliding piece E,
whereby the latter slides to and fro upon the guide plate E compelled by the rod D).
The plate E is pivotally connected to the columu C, in the same manner as the right
arm of the lever B, and thus the up and down movement of a valve spindle His
effected, upon the top of which it presses; the said motion is limited by the position
of a sloping plane B1, B2 adjusted upon the sliding piece E' and by the pressure of
a split-bar G, which moves under the influence of an eccentric placed upon the shaft
of the machine.
The method of operating the valves is clearly demonstrated by the sectional view
of the same in the drawing. The cylinder inlet valve H', which is secured to the
bar H normally supported by the spiral spring P, is depressed by the pressure of
the rod G acting more or less upon the same according as the regulator slides the
wedge shaped piece E backwards or forwards upon the plate E. The amount of
gas escaping past the inlet valve H determines the pressure in the mixing
chamber J. The pressure in the said chamber J' determines in its turn the ad-
mission of air and gas past the valve J. This valve corresponds in shape to the
valve H', and is fixed to the vertical column J". The said valve J is maintained pressed
upon its seating by the pressure of the spiral spring P¹. As soon as the pressure in the
chamber J is sufficiently diminished by the flow of the mixed gases to the engine
cylinder through the tube H2, the valve J rises under the pressure of the gas
passing through the cock L, tube M, and inlet N', whilst at the same time air
flows in through the opening K and passes up centrally around the column Ju
which does not completely fill the cylindrical space in which it works. As shewn
in the drawing the valve J has no mechanical connection with the valve H', but by
the arrangement described the inlet of the gas can be adjusted exactly to the
requisite amount, the means of regulation being the adjustment of the pressure of

page_text: the spiral springs which are suitably controlled by screw nuts or the like, and
the regulation of the gas pressure by means of the cock I.
As shown in the drawing the two valves are independent and not connected
together by any rod; it is consequently possible, to register perfectly the inlet of
the gas, and to place the valve spindle Jin a space which is larger than its
diameter, so that the same can serve as the inlet for the air passing in through K.
Upon the valve seat N, is provided an annular channel N', which is in com-
munication with the gas inlet M. In this manner the mixture of the air (passing
in through K) with the gas takes place each time in the annular channel N, when
the valve rises. This effects the result that the ignition of the mixture takes place
with great regularity and the motor works without jerks and equally whether it is
revolving at 300 or at 600 revolutions per minute.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
1. The application of a governor-ball-regulator A, to adjust a sloping plane B'
and 13 horizontally necording to the number of revolutions of the motor, which
apparatus is interposed between the free end of an inlet valve spindle II and an
eccentric rod operated from the motor shaft, in combination with the arrangement
of an inlet valve placed underneath the mixing space J, which space is so
arranged, with the air passing into a annular channel around the valve seat that
at each lift of the valve J the air enters into the said annular space N1, into which
through a channel M, the gas enters; so that at each lift of the valve J, the mixture
of air and gas and the flow of the same into the space J' takes place.
2. The apparatus for controlling and operating gas engines substantially as
described and illustrated in the accompanying drawings.
