I FREDERICK JOHNSON ALLISON, of 23 Gordon Street, Plaistow, in the County of
Essex, Paint Manufacturer, 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 object of this invention is to produce a simple and efficient oil lamp which-is
self-extinguishing from which no oil can escape when upset, and in which the danger of
explosion from the hydro carbon vapour becoming overheated is minimized.
The reservoir of the lamp is constructed on the principle of the unspillable ink
bottle and the aperture through which the oil is fed when refilling is so placed that no
more oil can be fed into the reservoir than will occupy more than at most one half
the capacity of the reservoir, so that no oil will flow through the central channel
when the lamp is upset. Over the outside of the wick tube an outer tube with wing
shaped projections is loosely placed so that when the lamp is up set this outer tube
will fall until the wing shaped projections thereon rest against the inside of the top of
the burner, the outer tube thus forming a temporary elongation of the wick tube and
effectually extinguishing the light in the same manner as if the wick were turned
down into the wick tube.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding parts in all the figures.
Figure 1. is a partly sectional elevation of a lamp constructed according to this
invention; and
Figure 2. is a plan thereof. + and
す
Figure 3. is a section of the extinguishing tube.
The body of the lamp is provided with two central inverted truncated cone shaped
shields or baffles A & B, the conical chamber (between them serving to keep cool
the vapour in the upper part D of the reservoir. E is the screw cap on the aperture f
through which the oil is fed when the lamp is being replenished, the said aperture
leading into a channel F branching off from the bottom part G of the reservoir of the
lamp.

page_text: The first lock 1 fasten on the Safe Chest door or other receptacle for which it is to
be used in the ordinary way by means of screws.
I then make one two three or four bars turned as screws and fix them upon this
first lock and they project therefrom-The bar or bars is or are made the necessary
length to receive the plate or plates nut or nuts and the second or other locks herein-
after mentioned.
I then take the second or other locks and make a hole or holes in it or them
corresponding to the projecting bar or bars and slide the second or other locks on the
projecting bar or bars and fasten the two or other locks rigidly together by means of
a nut or nuts.
I then take a plate or any number of plates I may desire to use made of wood iron
or other metal-say th of an inch in thickness-or any other thickness I may wish
to use with a hole or holes in it or them corresponding to the projecting bar or bars
attached to the first lock and also a keyhole made in the said plate or plates of wood
iron or other metal corresponding to the keyhole of the first lock to enable the key to
pass through to the second lock or other locks.
To obtain the permutations hereinafter claimed I unscrew the nut or nuts on the
projecting. bar or bars and take off the second lock or locks and slide the plate or
plates of wood iron or other metal on the projecting bar or bars close to the first lock
and then put the second lock or other locks on afterwards by the same means and
they are kept rigidly together by means of the nut or nuts on the projecting bar or
bars The nut or nuts are placed at the back of the second or other lock.
Instead of the plate or plates before mentioned I can use lock nuts on the projecting
bar or bars to adjust the different distances.
The plate or plates nut or nuts is or are marked with numbers or letters to corre-
spond with the key or keys to be used with the corresponding plate or plates nut
or nuts or if I use locks instead of plates or nuts they are numbered in the same
manner.
Instead of the plate or plates nut or nuts I can use locks.
1 do not confine myself to two locks but can use three or more.
The key for such combination I construct with two or more sets of wards on it and
such wards have a radial and a longitudinal adjustment so as to correspond to any
similar adjustment of my combined locks.
Fig. 1 of the accompanying drawings shews two locks screwed or bolted together;
and Figure 2 shews the key to be used therewith.
I supply one key for the two locks and one key for each lock I use instead of plates
as above mentioned and one for each plate or plates nut or nuts and such key or keys
is or are marked with a number or letter corresponding with the plate or plates nut
or nuts to be used-Should I use locks instead of plates or nuts they are numbered or
lettered in the same manner.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. My combination of locks provides a novel simple and inexpensive lock which is
practically unpickable.
2. That an infinity of permutations can be made by the double adjustments in
radial and longitudinal movements so that if it is suspected that a key has been copied
or lost the owner of my combination lock can easily and inexpensively alter the
relative positions of the lock or locks and use another key or alter the positions of the
wards on the key so that the key which has been copied or lost will be useless to open
the lock unless the said lock has been placed in statu quo.
3. That any number of locks of different constructions can be used as one lock by
means of my invention.
4. That two or more ordinary common locks combined by my invention can be
made practically unpickable.

1 FREDERICK JOHNSON ALLISON, of 23 Gordon Street, Plaistow, in the County of
Essex, Paint Manufacturer, 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 object of this invention is to produce a simple and efficient oil lamp which is
self extinguishing when upset, and in which the danger of explosion from the hydro
carbon vapour becoming overheated is minimized.
The reservoir of the lamp is constructed on the principle of the unspillable ink
bottle and the aperture through which the oil is fed when refilling is so placed that no
more oil can be fed into the reservoir than will occupy more than at most one half
the capacity of the reservoir, so that no oil will flow through the central channel
when the lamp is upset. Over the outside of the wick tube an outer tube with wing
shaped projections is loosely placed so that when the lamp is up-set this outer tube
will fall until the wing shaped projections thereon rest against the inside of the top of
the burner, the outer tube thus forming a temporary elongation of the wick tube and
effectually extinguishing the light in the same manner as if the wick were turned
down into the wick tube.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding parts in all the figures.
Figure 1. is a partly sectional elevation of a lamp constructed according to this
invention.
Figure 2. is a plan thereof; and
Figure 3. is a section of the extinguishing tube.
The body of the lamp is provided with two central inverted truncated cone shaped
shields or baffles A & B, the conical chamber C between them serving to keep cool
the vapour in the upper part D of the reservoir. E is the screw cap on the aperture f
through which the oil is fed when the lamp is being replenished, the said aperture
leading into a channel F branching off from the bottom part G of the reservoir of the
lamp.

page_text: In Figure 1, the lamp is shewn fully charged with oil when it has been replenished
by placing the lamp upon a table or other flat surface and the oil fed through the
aperture. When so replenished the oil just reaches to the bottom, or nearly so, of
the shield or baffle A. If now the lamp is upset the oil will run into the upper part D
of the reservoir which is made of such capacity that it will hold more oil than can be
fed into the lamp through the aperture in the manner hereinbefore described.
Should any of the oil be jerked or otherwise passed into the conical chamber the
inner baffle B will prevent it from flowing into the burner J. At the same time
when the lamp is upset the outer tube K will slide along the wick tube M until the
curved or wing shaped projections L thereon, rest against the top of the inside of the
burner J, thus forming an elongation of the wick tube M extending to the top of
the inside of the burner. The dotted lines shewn in Figure 1 represent the position
of the extinguishing tube K and the projections L when the lamp is upset.
When the lamp is set upright again the extinguishing tube K will slide over the
outside of the wick tube M until it falls into its normal position and the oil will
occupy the bottom part of the reservoir as before.
In the drawings a cheap form of lamp is shewn with a handle H and a flat wick,
but it is obvious that the same construction of lamp can be made to fit into a separate
stand or may be otherwise constructed as to its outward form or design and may be
provided with a circular wick if desired without departing from the nature of my
invention. In the case of a circular wick lamp it will only be necessary to make
the extinguishing tube K a double tube, instead of a single tube as shewn in
Figure 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
1. The construction and use of an unspillable lamp reservoir with two shields or
baffles A and B and a feeding aperture ƒ below the level of the bottom of the
shield or baffle B, the capacity of the upper part D of the reservoir being at least
one half that of the entire reservoir, substantially as and for the purpose hereinbefore
set forth and illustrated in Figures 1 and 2.
2. The construction and use of an extinguishing tube K sliding loosely over the
wick tube M substantially as and for the purpose hereinbefore set forth and illustrated
in Figures 1 and 3.
