PROVISIONAL SPECIFICATION.
Improvements in Hydro-carbon Motors and in Apparatus and
Appliances connected therewith.
We, JAMES EDWARDES WEYMAN, GEORGE HITCHCOCK and JAMES ARTHUR
DRAKE, all of the Church Acre Iron Works, Guildford, in the County of Surrey,
Mechanical Engineers, do hereby declare the nature of our said invention for
"IMPROVEMENTS
IN HYDRO-CARBON MOTORS AND
IN APPARATUS AND
APPLIANCES CONNECTED THEREWITH to be as follows:-
"
The object of our invention is to automatically regulate the temperature of the
vaporizer used in hydro carbon engines to vaporize the oil, but it is also applicable
for regulating the temperature in gas engines and as in either case the mechanism
and appliances will be similar, a description of our invention as applied to an oil
engine will suffice.
In such an engine we place the vaporizer at the back end of the cylinder of
the engine or other convenient position, we provide the cylinder with the usual
exit for the exhaust gases fitted with a controllable exhaust valve, we likewise
provide an additional exit fitted with a controllable valve, this additional exit being
so arranged as to pass through or around the vaporizer.
By means of the first exit herein referred to, the exhaust gases may, by the
usual means, be passed either into a silencing chamber and thence into the
atmosphere, or into the atmosphere direct, but by our additional exit, the exhaust
may be made to pass, first, through or around the vaporizer according to the
temperature which it is desired to maintain and in order that this may be effected
automatically we provide a rod of porcelain or other suitable substance sensitive to
the fluctuations in temperature and which we so place as to pass through from the
inside to the outside of the vaporizer in such a manner that the variations in its
length by the fluctuations of the temperature of the vaporizer may be made to
actuate the exhaust valves either direct, or by means of a lever or levers in
conjunction with wedges or stops or other convenient means, so arranged that the
valves may be opened or closed more or less, according to the direction into which
it is desirable to convey the exhaust gases so as to regulate the temperature of the
vaporizer to the required degree, thus, when the temperature of the vaporizer is not
sufficiently high, the sensitive rod contracts and the exhaust valves, leading the waste
gases round the vaporizer are opened or partly opened and the exhaust valve regulating
the exit by the usual course, is closed or partly closed, until the temperature has
reached its normal state, when, should the temperature become too high, the
expansion of the sensitive rod by means of the appliances herein referred to,
closes that means of exit for the waste gases, which then follow the usual course
until the temperature again falls to its normal state and vice-versa.
The temperature of the vaporizer being thus governed and regulated to any
required degree.

Improvements in Hydro-carbon Motors and in Apparatus and
Appliances connected therewith.
We, JAMES EDWARDES WEYMAN, GEORGE HITCHCOCK and JAMES ARTHUR
DRAKE, all of the Church Acre Iron Works, Guildford, in the County of Surrey,
Mechanical Engineers, do hereby declare the nature of our said invention for "IM-
PROVEMENTS IN HYDRO-CARBON MOTORS AND IN APPARATUS AND APPLIANCES
CONNECTED THERE WITH," and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:―
The object of our invention is to automatically regulate the temperature of the
vaporizer used in oil engines to vaporize the oil."
In such an engine we place the vaporizer at the back end of the cylinder of the
engine or other convenient position; we provide the cylinder with the usual exit
for the exhaust gases fitted with a controllable exhaust valve, we likewise provide
an additional exit fitted with a controllable valve, this additional exit being so
arranged as to pass through or around the vaporizer.
By means of the first exit herein referred to, the exhaust gases may, by the
usual means, be passed either into a silencing chamber and thence into the atmo-
sphere, or into the atmosphere direct, but by our additional exit, the exhaust may
be made to pass, first, through or around the vaporizer according to the temperature
which it is desired to maintain and in order that this may be effected automatically,
we provide a rod of porcelain or other suitable substance or appliance sensitive
to the fluctuations in temperature, such for example as a metallic rod or a tube or
cylinder provided with mercury actuating a piston and rod, which we so place as
to, pass through from the inside to the outside of the vaporizer, in such a manner
that the variations in the length of the sensitive rod or other appliance referred to,
by the fluctuations of the temperature of the vaporizer, may be made to actuate the
exhaust valves, either direct or by means of a lever and rod, or levers and rods,
in conjunction with wedges or stops or other convenient means, so arranged that
the valves may be opened or closed, more or less, according to the direction into
which it is desirable to convey the exhaust gases, so as to regulate the temperature
of the vaporizer to the required degree, thus, when the temperature of the vaporizer
is not sufficiently high, the sensitive rod if made of porcelain expands or if made of
metal or metallic substance contracts, or when mercury is employed, it, likewise
contracts and falls in the tube and by means of the appliances previously referred
to, the exhaust valve leading the waste gases through or around the vaporizer is
opened or partly opened and the exhaust valve regulating the exit by the usual
course, is closed or partly closed until the temperature has reached its normal state.
Should the temperature become too high the reverse action of the appliances herein
described takes place and the passage for the exit of the waste gases through or
around the vaporizer is closed or partly closed, and they then follow the usual course
until the temperature again falls to its normal state and vice-versa.
The temperature of the vaporizer being then governed and regulated to any
required degree.
The nature of our invention will be better understood on reference to the accom-
panying sheet of drawings in which
Fig. 1. is a vertical section taken through the vaporizer and rear end of the
cylinder of an oil engine.
Fig. 2. being a similar view partly in section shewing an alternative method of
regulating the flow of the waste gases.
The same letters refer to similar parts throughout the several views.
a, is the cylinder of an oil engine.
b, the vaporizer.
c, the usual exit for the exhaust gases.

page_text: e, the additional exit for the exhaust gases.
f, the controllable valve on the same.

h, the tube or cylinder provided with mercury.
i, i, the piston and rod working in the same.
j,j, the levers and rods by means of which the action of the sensitive rod or of
the mercury are communicated to the controllable valves d, f, and n, (Fig. 2).
k, k, are the wedges on the spindles of the valves d, & f.

lowered.
m, a regulating screw for adjusting the beat of the valves d, & f, by means of the
wedges and appliances k k and l.
n, (Fig. 2.) is a controllable valve employed in the alternative method for regu-
lating the direction of the exhaust gases.
o, being a passage into or through the vaporizer.

a manner similar to that described for the appliances shewn in Fig. 1.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is,

tion of parts and appliances shewn in Fig 1, by means of which the temperature of
the vaporizer may be automatically regulated, comprising the additional exit, e, for

of which the direction of the exhaust gases is regulated by the action of similar
sensitive automatic appliances described in Claims 1 and 2, in the manner and for
the purposes substantially as herein described and illustrated.
