We. FRANCIS WILLIAM CROSSLEY and FRANK HERBERT ANDERSON both o
Openshaw near Manchester in the County of Lancaster, Engineers do hereby declare
the nature of this invention to be as follows:-
Our invention relates to apparatus for igniting the combustible charge of a gas or
oil motor engine by admitting a portion of it into a tube heated by an external flame.
A cam driven by the engine acts on a roller mounted on the end of a lever. The axis
of this roller may be made adjustable in a slot of the lever so that it can be set to
receive movement from the cam a little sooner or later in the course of the revolution
of the cam. The lever which is pressed against the cam by a spring, is fixed on the
outer end of a rocking spindle which works in a hole bored in the ignition valve box.
The inner end of this spindle has on it a collar which is bevilled to seat as a valve on
a seating formed at the inner end of the hole through which the spindle passes, thus
preventing leakage past the spindle; and, the better to ensure tightness, the spindle
may be provided with a spring pressing the valve shaped collar against the seating.
In order to prevent clogging of the spindle by residues of burnt gases which may
leak past the valve collar, a groove is turned in the spindle just under the collar and a
passage is bored from this part of the spindle bearing to the outside of the valve box
to provide escape for such Huid as may leak past the collar. On the inner end of the
rocking spindle beyond its valve collar is fixed an arm the end of which projects
immediately under the stem of the ignition valve below the valve seating or under a
shoulder formed in a notch in the stem of the valvo above its seating. This valve is
situated in a passage forming a communication between the engine cylinder and the
interior of a heated tube. This passage is made with a part of it having considerable
capacity between the valve and the heated tube. When the cam acts on the lever,
turning the rocking spindle parily round, its arm raises the valve allowing a portion
of the combustible charge in the cylinder to pass into the heated tube whereby it is

page_text: ignited, and the ignition is communicated to the charge in the cylinder. In order to
give facility for taking out, cleaning, or repairing the ignition valve, it is situated in
a bore of the valve box covered by a cap, which when necessary can be taken off to
give access to the valve. When the arm which lifts the valve is arranged below its
seating, the valve can at once be lifted out of its place; and when the arm is arranged
to enter a notch in the valve stem above the seating, the lever and arm can be moved,
as the valve is lifted, sufficiently far to withdraw the end of the arm from the
notch.

page_text: We, FRANCIS WILLIAM CROSSLEY and FRANK HERBERT ANDERSON both of
Openshaw near Manchester in the County of Lancaster, Engineers, 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 :-
Our invention relates to apparatus for igniting the combustible charge of a gas or
oil motor engine by admitting a portion of it into a tube heated by an external flame,
as we shall describe referring to the accompanying drawings. Fig. 1 is an elevation
and Fig. 2 is a plan of the igniting valve box, cam and lever and Figs. 3 and 4 are
transverse sections respectively on X X and Y Y of Fig. 2. A cam A driven by the
engine acts on a roller B mounted on a lever C, with its bearing preferably in a slot
as shown, so that the roller can be adjusted to receive its movement from the cam a
little sooner or later in the course of a revolution of the cam. The lever C which is
pressed towards the cam by a spring Dis fixed on the outer end of a rocking spindle E
which works in a hole bored in the ignition valve box. The inner end of this spindle
has on it a collar e which is bevelled to seat as a valve on a seating formed at the inner
end of the hole through which the spindle E passes, thus preventing leakage past the
spindle, and, the better to ensure tightness, the spindle may be provided, as shewn
with a spring e pressing the valve shaped collar e against the seating. In order to
prevent clogging of the spindle by residues of burnt gases which may leak past the
valve collar e, a groove is turned in the spindle just under the collar and a passage e³
is bored from this part of the spindle bearing to the outside of the valve box, to
provide escape for such fluid as may leak past the collar. A lubricator F is arranged
to supply the spindle and its bearing with lubricant. On the inner end of the rocking
spindle E beyond the valve collar e is fixed a bent arm G the end of which projects
under a shoulder of a notch formed in the stem of a valve H above its seating.
This valve is situated in a passage I forming a communication between the engine
cylinder and the interior of a tube K which is situated within a chimney and is
heated by the flame of a burner L. The passage I is made with parts of it i having
considerable capacity to receive such inert gases, residues of previous combustion
products, as may occupy the passage from the cylinder to the tubo, when they are
comprossed by being subjected to the pressure of the compressed cylinder charge.
When the cam A acts on the lever C turning the rocking spindle E partly round, its
arm G raises the valve H and this allows a portion of the combustible charge to pass
from the cylinder into the heated tube K whereby it is ignited, and the ignition is
communicated to the charge in the cylinder. In order to give facility for taking out,
cleaning or repairing the ignition valve H, it is situated in a bore of the valve box

page_text: overed by a cap M which can be taken off when necessary to give access to the valve.
As the valve His lifted out of its bore, the lever C moves downwards sufficiently to
disengage the arm G from the notch of the valve stem.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed we declare that what we claim is :-
The construction and use of ignition apparatus for gas or oil motor arranged and
operating substantially as described with reference to the accompanying drawings.
