COMPLETE SPECIFICATION.
An Improved Lime Light Apparatus and Saturator for use in
connection with Bi-unial, Side-by-Side, and other Optical
Lanterns.
We, JOSEPH RILEY, of 5 Cheapside, Bradford, in the County of Yorkshire,
Stuff Manufacturer, and WILLIAM LAWSON, of Rectory View Newton-le-
Willows, in the County of Lancaster, Engineer, 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, which is partly a new invention and partly an improvement on
the invention described in the Specification of the Patent No. 20628 of 1892,
relates to an apparatus for the production of lime light for use in connection with
bi-unial, side by side, and other optical lanterns.
The object of this invention is to construct apparatus with a case which is divide I
so as to make about the same quantity of gas that is required for one saturator,
serve for two saturators, or one double saturator, and to regulate the light so as to
obtain dissolving views by means of optical lanterns such as are herein before
named.
In the accompanying sheets of drawings illustrating our invention,
Fig. is a front elevation of a lime light apparatus and saturator constructed
according to this invention.
Fig. 2 is a sectional elevation of the same drawn through line A. A on Fig. 3
which represents a sectional plan view drawn through line B. B, in Figs. 4 and 5:
Fig. 4 is a transverse sectional elevation drawn through line C. C, and Fig. 5 is a
transverse sectional elevation drawn through line D. D, both in Fig. 1.
Fig. 6 represents a modification of our invention adapted for a side by side
lantern.
In this invention we construct a case such as a with an internal division a' as in
Fig. 3, and duplicate pillars a² and a³ : In the centre of each of these pillars we
place vertically the tubes and 2, the lower ends of said tubes being fitted
respectively into a transverse tube and valve carrier af and a formed within the
case . We construct gas passages 13 and in the aforesaid transverse tube
carrier a and the passages, 16 and 17 in the tube carrier a³; through these
passages the supply of oxygen gas that is caused to enter through the nozzle c
from a gas bag or other reservoir is conducted to the top and bottom jets d and d¹.
We place diaphragms hand within a short distance of the bottom of the
case a and pack the spaces in the case and the pillars a' and a² with saturating
material as described in the Specification of the Patent herein before named.

In order to light the jets d'and, the handles e and e¹ Fig. 3 are placed in a
straight position at right angles to the front of the case a, when the slots and
will come respectively opposite the passages and thereby permitting the gas to
pass from the nuzzle e through the passages e, c², and, and enter the said
passages and 6 passing out into the lower portion of the case a through the
diaphragms and and is distributed through the saturating material in the
spaces.
A portion of the saturated gas will enter the tube j, Fig. 4, in the manner
indicated by arrows, and pass along the passage b to the top jet d, and a portion of
said gas will enter the upper end of the tube and pass down said tube and
through the passage to the bottom jet : The top jet will be full on when the
handle e is placed to the extreme right, and the bottom jet will be full on when
the handle is placed to the extreme left. In the positions in which the handles e

page_text: and are shown in Fig. 3 on the drawing, the bottom jet will be supplied with
only the small quantity of gas that will be able to pass through the nick, and
the top jet will have a fuil supply of gas from the passage, and a correspondingly
reverse position of said handles will cause the top jet to be supplied with the small
quantity of gas that can pass through the nick and the bottom jet will then be
full on both jets may be altered simultaneously at the will of the operator, by
connecting the handles e and e¹ with a link such as e2; a stop e may be attached as
shown in the recess ef that will regulate the travel of the handles e and e', and
prevent the light from either jet being totally extinguished when changing a picture
from one lens to the other.
In order to obtain the necessary brilliancy in either of the jets, or to diminish or
increase the light as required when the picture is being shown, the handles e and e¹
are turned to one side or the other so as to permit a supply of pure oxygen to enter
in greater or less quantities the passages 3 and 4. The pure oxygen that enters
the passage will pass up the tube and mix with the saturated gas at 6 Fig. 4,
and the gas that passes along the passage will mix with the saturated gas at d*,
Fig. 5.
When the apparatus is required to be employed with a side by side lantern, the
jets will be placed one at either side of the base, and the handles will be operated
in the manner herein before described. is the lime carrier for the bottom jet,
and q the lime carrier for the top jet.
The case may be charged by removing the plugs m and n.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1st. In apparatus employed for producing lime light for use in connection with
bi-inial, side by side and other optical lanterns, the combination of taps or cocks
with gas passages in a duplicate case such as a with pillars a² and 3 or their
equivalents, by which two burners or jets may be manipulated, so as to obtain with
the same or nearly the same supply of gas as is required for a single saturator,
either two full lights, or one full light and one diminished light in the manner
substantially as herein before described.
2nd. In apparatus employed for producing lime light for use in connection with
bi-unial, side by side, and other optical lanterns, the combination of a connecting
link such as with taps or cocks e and e¹ for regulating the admission of gas to
the jets so as to obtain simultaneous action with both of said taps or cocks in the
manner and for the purpose substantially as herein before described.
3rd. Apparatus employed for producing lime light for use either inside or outside
bi-unial, side by side, and other optical lanterns in combination with taps or cocks
and gas passages in a case, substantially as, and for the purposes herein before
described.
