Complete Specification Left, 25th Nov., 1898-Accepted, 7th Jan., 1899
PROVISIONAL SPECIFICATION.
Improvements in and relating to Igniting Apparatus for Gas and
Vapour Engines.
We, ALGERNON JASPER LYON, Gentleman, of 22, St. Andrews Street, and
GEORGE FREDERICK WHITMORE, Gentleman, of Hills Road, both in Cambridge, do
hereby declare the nature of this invention to be as follows:
This invention relates to igniters such as are described in the Specification
No. 28117 of 1896 which consist of an outer tube having a platinum capsule.
at one end and an inner tube by which a blast of benzoline vapour and air is
directed onto the inside of the capsule.
In place of fixing the capsule to the outer tube and screwing the latter into
a hole in the wall in the cylinder as described in the former specification we
now fix the capsule in the hole by means of an asbestos or other suitable washer
and a nut. The inner tube is attached to the outer tube and the latter is mounted
on guides so that it can be moved away from the cylinder to ignite the vapour
issuing from the inner tube. It is provided with a conical nose, and if preferred
with or without a bayonet or other suitable joint, which when the tube is in place
fits into a conical seat in the nut. Preferably the outer tube is carried by an
arm fixed to a sleeve free to slide on a rod projecting from the cylinder and
secured to it by a set screw or spring. The arm may have pivotted to it a second
arm having a small dish at its end which when the outer tube is drawn back. can
be turned under the end of the inner tube, or the dish may be permanently fixed
on the main arm. By burning a small quantity of spirit in the dish the vapour
issuing from the inner tube can be readily ignited.
Dated this 25th day of February 1898.

We, ALGERNON JASPER LYON, Gentleman, of 22, St. Andrews Street, and
GEORGE FREDERICK WHITMORE, Gentleman, of Hills Road, both in Cambridge, 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 igniters such as are described in the Specification

Figures 1 and 2 are longitudinal sections of part of an engine fitted with an
igniter in accordance with this invention. Figure 1 shows the position of the
parts when in use and Figure 2 shows the outer tube drawn back ready for
lighting. Figures 3 are detached views of the capsule and washer.
C
a is the capsule, 6 the washer and c the nut securing the capsule to the cylinder.
d and e are the inner and outer tube respectively. is the platinum sponge
(described in the former specification) at the end of the tube d and e¹ is the vent
from the tube e. The tubes d and e are carried by the arm f fixed to the sleeve f¹
which is free to slide on the rod y projecting from the cylinder and secured to it
bly the set screw g¹. h is a dish carried by the arm which is pivotted at h² to
the arm f.
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:-
1. The method of fixing the capsule substantially as described.
2. The combination of a fixed capsule with a movable inner and outer tube
substantially as described.
3. Igniting apparatus for gas and vapour engines substantially as described and
illustrated by the drawings.
