PROVISIONAL SPECIFICATION.
Improvements in Gas Supply Regulating Apparatus for Magic
Lanterns and other Purposes.
We JAMES EDWARD ANDERSON of 35 Meredith Street Clerkenwell in the County
of Middlesex Lantern Maker, and Louis EDMOND PERKEN, FREDERIC LOUIS
PERKEN and ARTHUR RAYMENT trading as Perken Son & Rayment of 99 Hatton
Garden in the County of Middlesex Wholesale Opticians do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in taps & cocks or gas supply regulating
apparatus or appliance of a novel character and is applicable to a number of purposes
but is especially adapted for regulating and controlling the supply of gas to magic
lanterns.
For this purpose we will describe the present invention as adapted for a "six-
way" gas supply regulating apparatus (though it can be arranged for a greater or
less number if desired) for a treble" magic lantern.
In a block of brass or other suitable material are arranged longitudinally the main
supply pipes for oxygen and hydrogen gases respectively.
Between these are arranged three valves or plugs each such valve having a slot
or groove formed on two sides thereof opposite to each other-which when brought
opposite a suitable pipe or opening from the main supply pipes will allow the oxygen
gas on one side and the hydrogen gas on the other to pass to an outlet hole or pipe
respectively on each side whence it is led to the point of ignition.
"
A "bye-pass" from each outlet pipe on one side to the main supply pipe on the
same side is provided so that the light in each individual lantern can be turned up
full at any moment and a screw or other convenient appliance is provided to each
bye-pass so that both gases may be shut off entirely from any lantern (or
lanterns) independently of the others and thus prevents any escape of gas or fear of
explosion taking place when any one or more lantern is not being used with the
other or others.
For further security the valves may be formed with any convenient appliance to
lock and secure the same in position when turned "off" and out of use-as for
instance a small lug or projection on the valve or plug through or onto which a set
screw acts to rigidly secure same.

For this purpose we will describe the present invention as adapted for a 'six-
way" gas supply regulating apparatus (though it can be arranged for a greater or
less number if desired) for a <
triple" magic lantern.
And in order that this invention may be easily understood and readily carried into
practice we will proceed to fully describe same with reference to the accompanying
sheet of drawings in which
Figure 1 shows a plan of the top of the valves in their positions in the apparatus.
Figure 2 being a side elevation looking in the direction of the arrow a Figure 1.
Figure 3 is a sectional side elevation on line 1-1 Figure 1 the valves or plugs
being shown in elevation and not in section.
Figure 4 is an exterior end view of apparatus looking in the direction of the
arrow z Figure 1, and
Figure 5 is a similar view in section on the line 2-2 Figure 1.
Similar letters of reference indicate corresponding parts throughout.
In a block of brass or other suitable material a are arranged longitudinally the
main supply pipes 6 for oxygen and c for hydrogen gas respectively.
a
Between these are arranged three valves or plugs d e f each such valve having
slot or groove i formed on two sides thereof opposite to each other-which when
brought opposite a suitable pipe or opening 9 from the main supply pipes b and c
respectively will allow the oxygen gas from the main supply pipe 6 on one side to
pass through a passage to an outlet pipe on the same side and from thence it is
led to the point of ignition and in like manner the hydrogen main supply pipe c
communicates through the passage g and slot i of any of the plugs d e and with the
passage and thence to its respective outlet pipe c¹ (on the same side of the
apparatus as the main c) and thence led away to the point of ignition.
Thus it will readily be seen that by turning any one of the valves d e or finto the
position shown in all the figures of the drawings both the different gases will be
simultaneously turned on and by turning the valve a quarter turn either one way or
the other both gases will be turned off thereby without either of the said gases
meeting each other in the apparatus.
"
A "bye-pass" m from each outlet pipe b¹ or c¹ respectively on one side to the
main supply pipe bor c respectively on the same side is provided as shown so that
the light in each individual lantern can be turned up full at any moment and a
screw n or other convenient appliance is provided to each "bye-pass
m so that
both gases may be shut off entirely from any lantern (or lanterns) independently of
the others and thus prevents any escape of gas or fear of explosion taking place
when any one or more lantern is not being used with the other or others.
For further security the valves may be formed with any convenient appliance to
lock and secure the same in position when turned "off" and out of use-as for
instance a small lug or projection o on each valve or plug d e and f respectively
through which a set screw p acts to rigidly secure same when desired that is when
the particular lantern supplied with its gases through the particular valve de or fis
not being used.
By these means the operator is enabled to easily control the dissolving effects in a
magic lantern as by simply turning any single valve the two gases (i.e. hydrogen
and oxygen) are simultaneously regulated in exactly the same manner and this
apparatus will be found especially adapted for obtaining good dissolving effects in
magic lanterns as well as for its great convenience and improvement in other
respects.
It will be obvious that this appliance may be used for regulating and controlling
(in the manner described) any suitable gases for magic lanterns or for other
purposes to which it is applicable.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A gas supply regulating apparatus consisting of a metal block a in which two

page_text: main gas supply pipes b and c are formed longitudinally therewith and having
arranged between them two three or more plugs or valves such as d e or f with slots i
on two opposite sides thereof which latter when brought opposite each main supply
pipe b and c allow the respective gases therefrom to pass by suitable passages to the
respective outlets 6¹ and c¹ and thence to-the point of ignition substantially in the
manner and for the purposes herein before described and represented in the drawings
hereunto annexed.
