and convey
take a cylinder of brass or other suitable metal as shown at Fig.
compressed oxygen gas from a steel cylinder or gas bag through a T piece (A)' by
releasing screw (A 1) and convey it forward through a channel bored out of the
casting into the gas diffusion chamber (B) the sides and top of which are fluted or
corrognated as shown at (B Fig. 3) the said chamber being then covered over the
top and around the sides with a dome shaped cap shown at (C Fig. 1).
This chamber being filled with oxygen gas under pressure, the gas is forced out
of the said diffusion chamber down the flutings around the whole circle shown
at (B) Fig. 3 and by those means is equally distributed in the direction of the
arrows (Fig. 1) through the whole interior of the aforesaid cylinder (D) which is
stuffed with absorbent material charged with ether or benzoline in accordance
with the usual custom, the said ether or benzoline being admitted at the top after
removing the screw cap E.
The oxygen gas passing on all sides through this absorbent material charged
with ether decends the projecting tube (F) at the top and is driven forward to the
Dozzle (G) where it ignites on the application of a light.
The screw marked (H) is then slackened which allows the gas under pressure to
enter the tube (2) and is driven forward past the tube (F) where it meets the
etherised oxygen gas carrying it forward through the spiral tube (J) where it
swirls and dashes against the sides of the said spiral tube breaking up the ether
into minute particles and perfectly mixing the oxygen gas therewith, and after
being emitted from the nozzle (G) the vapourised ether and oxygen gas now
mixed together play upon a bobbin of lime at (K) producing a brilliant and
intense white light due to the pressure of oxygen and the perfect blending of the
ether or benzoline therewith.

aforementioned apparatus inside the lantern, and also for adjusting the light with
the focal plane of the lantern condensor which I do in the following manner.
In the centre of the cylinder 1 fix a tube (1) into which the screwed pillar (2)
fits forming an axis around which the aforesaid cylinder is made to revolve when
moved by the pinion (3) which works in a quadrant wheel fitted underneath the
cylinder at (4) the said pinion being held firmly in the desired position by tightening
the milled headed screw (5).
The apparatus is lifted vertically or lowered by meaus of a pair of bevelled
wheels (6) fitted in a frame the larger and horizontal one being screwed to and
revolving around the screwed pillar (2) when put in motion by turning the
pinion (7) which passes through the pinion (3) and gives motion to the small
bevelled wheel (8) thus bodily lifting the lime light apparatus into the desired
position.
The longitudinal motion is secured by a threaded screw passing through the
base of the stand, the said screw being fixed into the ends of a tray (9) inside
which the base of the stand slides in grooves when moved by the aforesaid screw
or a rack & pinion as preferred.

COMPLETE SPECIFICATION,
Improved Ether Saturator for the Production of the Lime Light.
I WILLIAM HOULDERSHAW of Hightown Heights Liversedge in the County
of York Dealer in Optical Goods 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 :-
The purpose of this invention is to secure primarily for the optical lantern in all
its varied forms a simple, powerful, penetrating white light free from danger,
easy of manipulation and providing for the perfect registration of the said light
with the focal point of the lantern condensors by mechanical means, put into
operation from the back of such lantern and eutirely away from the source of
heat.
Fig. 1. (on drawings left with the Provisional Specification) is a complete
section of the entire apparatus.
Fig. 2 shows another method of adjusting the position of the gas jet in relation
to the focal point of the lantern condensor by rack & pinion motion and provides
a vertical motion only in place of the universal motions shown in Fig. 1 the said
vertical motion being achieved as follows. (a) is a cylinder the interior (B) of
which receives a mixture of ether & oxygen in the same manner as (G) Fig. 1.
The cylinder (a) slides inside the circular groove (c) a gas tight joint being
obtained by an asbestos or soft metal washer pressed inside the stuffing box (D)
with the screw plug (e). On one side of the cylinder (a) is cut a number of
teeth (F) which engage with the pinion (G) one end of the pinion having a
milled head fastened thereon the turning of which raises or lowers the cylinder (a)
and thus regulates the height of the nozzle.
Fig. 3 is a horizontal section of the cylinder showing the method of revolving
and locating the lime and also the fluted gas passages leading from the diffusion
chamber B to the saturating portion of the apparatus and also the triangular
projection (c) which carries the lime bracket (e) & which is sliaped to maintain
the lime bracket in an upright position.
Figs. 4 & 5 are horizontal and vertical sections of an attatchment for use with
the mechanical stand shown in Fig. 1 in order to make the said stand with its

page_text: universal motions available for use with the ordinary limelight jets. The tube (a)
is arranged to fit over the screwed pillar of stand (2) Fig. 1. The quadrant of
teeth (B) engaging with the pinion shown at 4 Fig. 1. The tubes of an ordinary
oxy-hydrogen jet are shown in position at (c) (c) and method of clamping and
maintaining them in that position is by tightening the milled edged nut at (D).
I will now describe the method by which the aforementioned objects are attained.
I take a cylinder of brass or other suitable metal as shown at Fig. 1 and convey
compressed oxygen gas from a steel cylinder or gas bag through the T piece A
(in accordance with custom,) and by releasing screw valve A 1 convey it forward
through a channel bored out of the casting into the gas diffusion chamber B the
sides and top B1 of which are fluted or corrugated the side fluting being shown
in section at B Fig. 3, the said chamber being then covered over the top and around
the sides with a dome shaped cap shown at C Fig. 1.
This chamber being filled with oxygen gas under pressure the gas is forced out
of the said diffusion chamber down the flutings around the whole circle shown
at B Fig. 3, and by these means is equally distributed in the directions shown by
the arrows Fig. 1 through the whole interior of the cylinder D Fig. 1, which is
filled with absorbent materials charged with ether or benzoline in accordance
with the usual custom, the said ether or benzoline being admitted into the said
cylinder at the top after removing the screw cap E.
The oxygen gas passing on all sides through this absorbent material becomes
charged with ether or benzoline and decends the projecting tube F Fig. 1 at the
top and is driven forward to the nozzle G where it ignites on the application of a
flame.
The screw valve marked H is then slackened which allows the gas under
pressure to enter the tube i Fig. 1 and is driven forward past the tube F where it
meets the etherised oxygen carrying it forward through the spiral tube J where
it swirls and dashes against the sides of the said spiral tube breaking up the ether
into minute particles and perfectly mixing the oxygen gas therewith and after
being emitted from the nozzle G the vapourised ether and oxygen gas now mixed
together play upon a bobbin of lime at K producing a brilliant and intense white
light due to the pressure of oxygen and the perfect blending of the ether or
benzoline therewith.
Having obtained the light I now adopt mechanical means for securing the
aforementioned apparatus inside the lantern, and also for adjusting the light with
the focal plane of the lantern condensors which I do in the following manner.
In the centre of the cylinder I fix a tube (1) into which the screwed pillar (2)
fits forming an axis around which the aforesaid cylinder is made to revolve,
when moved by the pinion (3) which works in a quadrant wheel fitted underneath
at point (4). The said pinion being held firmly in the desired position by
tightening the milled headed screw (5). The apparatus is lifted vertically or
lowered by means of a pair of bevelled wheels (6) fitted in a frame, the larger and
horizontal one being screwed to and revolving around the screwed pillar (2) when
put in motion by turning the pinion (7) which passes through the pinion (3), and
gives motion to the small bevelled wheel (8), thus bodily lifting the lime light
apparatus into the desired position. The longitudinal motion is secured by a
threaded screw passing through the base of the stand, the said screw being fixed
into the ends of a tray (9) inside which the base of the stand slides in grooves when
moved by the aforesaid screw or a rack & pinion as preferred.
Having now particularly described and ascertained the nature of my said
invention and in what manuer the same is to be performed I declare that what
I claim is
1. The use of this apparatus for the magic or optical lantern in its single,
double, or triple forms, whether placed or fixed above each other or side
by side.

page_text: 2. Also its use in theatrical, or photographic work, on pit banks, on the railway,
on board ship, or other illumination.
3. Also the application of the mechanical stand with univeral motions as figured
herein to the ordinary gas and spirit jets used in the production of the limelight for
the optical lantern by means of the attachment shown in Figs. 4 and 5.
4. The precise form of diffusion chamber with fluted gas passages and methods
shown of equally distributing the oxygen gas through the aforesaid saturated
material inside the cylinder substantially as shown and herein described.
5. The form of internal tubes herein adopted for conveying the gases, and the
spiral or cork screw shaped tube for splitting up and vapourising the ether
particles and for securing the more perfect mixing of the oxygen gas therewith
substantially as shown and hereinbefore described.
