PROVISIONAL SPECIFICATION.
Improvements in Oil Engines.
ALFRED JAMES POOL, Engineer, of Elms Green, Chipstable, in the County
of Somerset, do hereby declare the nature of this invention to be as follows:-
This invention relates to engines, that vaporize the oil internally, and ignite
spontaneously, the clearance space I jacket with air, which I obtain from a fan, or
by conducting the air, from the periphery of the flywheel, I have a regulating
device, to regulate the quantity passing through the jacket, in the centre or near
the centre of the clearance space, I place the vaporizer, upon which the oil is forced
direct from the pump, which is controlled by the action of a governor. The most
novel part of my invention, consists in timing the igniting period, were there no
provisions made for such, the engine would ignite too soon, when driving heavy
loads. This I accomplish by injecting the oil on to the vaporizer, at various
parts of the cycle, this adjustment is made when the engine is in motion. This
arrangement allow the oil to be injected from the exhaust to the compression
stroke, in the Otto cycle.

Improvements in Oil Engines.
ALFRED JAMES POOL Engineer of Elms Green Chipstable Somerset 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 relates to engines, that vaporize the oil internally, and ignite
spontaneously, the clearance space, 1 jacket with an air current, which I obtain
from a fan, or by conducting air. from the periphery of the flywheel, I have a
device for regulating the quantity passing through the jacket, in or near the centre
of the clearance space, I place the vaporizer, upon which the oil is forced direct
from the pump, which is controlled by the action of a governor, preferably a
centrifugal, this governor allowing the pump, more or less stroke, and preventing
its action altogether, when the limit of revolutions is exceeded.

page_text: I have a novel means for timing the ignition period, this is accomplished by
injecting the oil sooner or later into the clearance space, on the vaporizer, this
adjustment I can make while the engine is in motion, I accomplish this object by
various arrangements, but I prefer the following, Upon the side shaft, I put two or
more cams in advance of one another, I either slide the said cams, on the side
shaft, or the roller on the pump lever, to bring either cam in action, thus
injecting the oil at various parts of the Otto cycle, from the exhaust to the
compression stroke.
In order that my invention may be fully understood, and the general
arrangements for carrying the same into effect, I refer to the accompanying
drawings,
