PROVISIONAL SPECIFICATION.
Improvements in Lamps.
We, THOMAS WILLIAM WILSON of 12 Tyndall Street West Bromwich,
Moulder, and HARRY BUTLER, Jervoise Street West Bromwich, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object the construction of a metal lamp in such a manner
that when from any cause the lamp is upset, the oil container will not be emptied
by such upsetting.
The oil lamps now in general use are made with bulbous shaped containers such
containers being formed with small threaded passages, and the burner part of each lamp
being formed with a screwed shank taking into the threaded passage of container: lamps
inade in the manner described are dangerous to use, because the imperfect fit of the
burner shanks when such burners are screwed in by a woman, a child, or other person
unacquainted with mechanical construction permits the threads of the screw on the
shank part of the burner to be damaged by being cross-screwed into the threaded
socket. To such an extent is this understood by lamp makers that burners are
made with taper threaded shanks so that the threads of such taper threaded shanks
will better hold in the sockets of containers although screwed in crosswise a
connection is thereby made of sufficient rigidity to allow of the lamp being lighted
and used but when the same is accidentally upset, the burner is jolted out of its
socket thus instantaneously emptying the container of its contents and causing
ruinous explosion or conflagration. To remedy the defects of the old methods of
making lamps, we in carrying out our invention provide any convenient shaped
stand, foot, bracket, or hanger such stand, foot, bracket, or hanger being furnished
with one or more container-supports in accordance with the height or length of such
stand, foot, bracket, or hanger.
We next provide the oil-container with the distinct improvements hereinafter set
forth.
By the first modification of our invention we use containers of the ordinary shape
made out of metal, glass or other suitable material but provide a vertical thimble
part over the threaded socket, such thimble part being of larger diameter than the
threaded socket, we form on the shank end of the burner part a guiding collar the
external diameter of which would correspond with the internal diameter of
the thimble in connecting such improved burner part to the lamp the screwed end
of the shank would be passed through the vertical thimble part of container-
socket and lowered towards the thread formed in the socket, the guiding collar part
of shank passing into the thimble and sliding down the thimble, thereby moving the
male screw of shank vertically true, so that the threaded end of such shank would
be in a proper position to engage with the first thread of the socket-screw by
rotating the burner part in the usual manner, the plug and socket would form a
mechanically perfect joint.
By a second modification of our invention we, dispense with the burner plug-joint
and make the burner in one piece with the upper part of container, then form such
upper part of container to screw on to, or into the lower part in the following
manner; the burner part of such containers would be formed in one piece with the
upper portion or lid, or such burner part would be formed separate and afterwards
amalgamated with the upper portion of lid. The lid would be provided with
projecting ears, or thumb-pieces to facilitate the easy rotation and tightening up of
the lid onto or into the container.
The combined lid and burner would be connected to the container by forming on
the lid a peripherical male thread such thread or screw being produced by any

page_text: suitable mechanical means, a guiding collar or flange being also provided above the
threaded part in the manner described in the first modification in relation to shank
end of burner.
The receiver would in a like manner be provided with an internal periphical
female screw-thread over which would be provided the vertical wall equivalent to
the thimble part described in the first modification; it will be apparent that the lid
of container carrying the burner must be removed when the lamp is filled, a large
basin shaped reservoir will then be presented to view into which to pour the lamp-
oil, the lid when afterwards lowered in position would by the action of the flange of
such lid against the vertical periphical internal wall of container be guided and
supported in a truly vertical position so that the screw would connect without
crosswinding.
The flange of lid is made of sufficient length to engage with the vertical wall of
container and at the same time allow the male thread of said lid to screw or take
into the female threads formed in rim of container.
The periphical edge of lid can in some cases be made to screw over the container
although we prefer to screw it within the container.
A lamp made with our improved thimble and collar as described in the first
modification or fitted with the combined burner and lid described in second modifi-
cation would if upset remain comparatively safe, the chimney would be broken but
oil could only pass through the wick, the flame would not be increased, the falling
of our improved well made lamp would rather tend to extinguish the light than to
increase it.
As a further security we can where desired provide a suitable locking bolt to pass
through the periphery of lid and through the periphery of container in the second
modification, or through the collar of plug and through the collar bearing surface
of socket in the first modification or through any other suitable part so as to lock
the lid securely in. position when screwed up tightly.

Improvements in Lamps.
We, THOMAS WILLIAM WILSON of 12 Tyndall Street, West Bromwich
Moulder, and HARRY BUTLER, Jervoise Street, West Bromwich, 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 has for its object the construction of a metal lamp in such a
manner that when from any cause the lamp is upset, the oil container will not be
emptied by such upsetting.
The oil lamps now in general use are made with bulbous shaped containers such
containers being formed with small threaded passages, and the burner part of each lamp
being formed with a screwed shank taking into the threaded passage of container lamps
made in the manner described are dangerous to use, because the imperfect fit of the
burner shanks when such burners are screwed in by a woman, a child, or other
person unacquainted with mechanical construction permits the threads of the screw
on the shank part of the burner to be damaged by being cross-screwed into the
threaded socket. To such an extent is this understood by lamp makers that burners
are made with taper threaded shanks so that the threads of such taper threaded
shanks will better hold in the sockets of containers although screwed in crosswise a
connection is thereby made of sufficient rigidity to allow of the lamp being lighted
and used but when the same is accidentally upset, the burner is jolted out of its

page_text: ocket thus instantaneously emptying the container of its contents and causing
uinous explosion or conflagration. To remedy the defects of the old methods of
aking lamps, we in carrying out our invention provide any convenient shaped
tand, foot, bracket, or hanger, such stand, foot, bracket, or hanger being
urnished with one or more container-supports in accordance with the height or
ength of such stand, foot, bracket, or hanger.
We next provide the oil container with the distinct improvements hereinafter set
orth.
By the first modification of our invention we use containers of the ordinary shape
nade out of metal glass, or other suitable material but provide a vertical thimble part
over the threaded socket, such thimble-part being of larger diameter than the
guiding collar the
hreaded socket, we form on the shank end of the burner part a
external diameter of which would correspond with the internal diameter of
the thimble in connecting such improved burner part to the lamp the screwed end
of the shank would be passed through the vertical thimble part of container-socket
and, lowered towards the thread formed in the socket, the guiding collar part of
shank passing into the thimble and sliding down the thimble, thereby moving the
male screw of shank vertically true, so that the threaded end of such shank would
be in a proper position to engage with the first thread of the socket-screw by
rotating the burner part in the usual manner, the plug and socket would form a
mechanically perfect joint.
By a second modification of our invention we dispense with the burner plug-
joint and make the burner in one piece with the upper part of container, then
form such upper part of container to screw on to, or into the lower part in the
following manner, the burner part of such containers would be formed in one
piece with the upper portion or lid, or such burner part would be formed separate
and afterwards amalgamated with the upper portion of lid. The lid would be
provided with projecting ears, or thumb pieces to facilitate the easy rotation and
tightening up of the lid onto or into the container.
The combined lid and burner would be connected to the container by forming
on the lid a periphical male thread such thread or screw being produced by any
suitable mechanical means, a guiding collar or flange being also provided above the
threaded part in the manner described in the first modification in relation to shank
end of burner.
The receiver would in a like manner be provided with an internal periphical
female, screw thread over which would be provided the vertical wall equivalent
to the thimble part described in the first modification; it will be apparent that
the lid of container carrying the burner must be removed when the lamp is filled, a
large basin shaped reservoir will then be presented to view into which to pour the
lamp oil, the lid when afterwards lowered in position would by the action of the
flange of such lid against the vertical periphical internal wall of container be guided
and supported in a truly vertical position so that the screw would connect without
crosswinding.
The flange of lid is made of sufficient length to engage with the vertical wall of
container and at the same time allow the male thread of said lid to screw or take
into the female threads formed in rim of container.
The periphical edge of lid can in some cases be made to screw over the container
although we prefer to screw it within the container.
A lamp made with our improved thimble and collar as described in the first
, modification or fitted with the combined burner and lid described in second modifi-
cation would if upset remain comparatively safe, the chimney would be broken but
oil could only pass through the wick, the flame would not be increased, the falling
of our improved well made lamp would rather tend to extinguish the light than to
increase it.
5 As a further security we can where desired provide a suitable locking bolt to
pass through the periphery of lid and through the periphery of container in the
second modification, or through the collar of, plug and through the collar bearing

page_text: surface of socket in the first modification or through any other suitable part so as
to lock the lid securely in position when screwed up tightly.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is constructed and used similar letters refer to
similar parts throughout the several views.
Figure 1 represents a side elevation of lid and burner constructed as to be
removable in one piece.
Figure 2 represents a view of container partly in section and partly in
elevation.
Figure 3 represents a portion of lid of the class suitable to screw over
container.
Figure 4 represents a portion of container on which is provided an outward screw-
thread suitable to receive the lid part Figure 3.
Figure 5 represents the improved plug part of burner described in first
modification.
Figure 6 represents an ordinary container the mouth or socket of which is
provided with our improved thimble.
In carrying out the first modification of our invention we provide a vertical
thimble part a over the threaded socket, as shewn at Figure 6 and we form on the
shank end of burner part, the guiding collar b.
In connecting the burner part to container c the screwed end d would be passed
through the thimble part a and lowered towards the threaded part e, the guiding
collar passing into the thimble a and by so passing in and taking a vertical and
true bearing thereby move the male screw threaded shank d vertically true so that
the first thread on end of plug would be in a mechanically true position to engage
with the first thread of internally screwed socket e by then rotating the burner
part g in the usual manner, the plug and socket would form a mechanically perfect
joint.
In carrying out the second modification of our invention we combine the burner
with the upper portion of the container and so form one removable piece as
illustrated at Figure 1, such removable piece may be made in separate parts for
convenience and afterwards consolidated into one part by soldering, brazing,
screwing, compressing and expanding or by any other suitable mechanical means,
we provide two thumb pieces by means of which the removable part Figure 1 can
be tightened up within the container.
j
We form on the lid a periphical male screw thread ; and a periphical guiding
collar as described in the first modification; the receiver is provided with an
internal screw thread mover which is provided the vertical wall n equivalent .to
the thimble part a described in first modification.
When the lid part Figure 1 is removed from the container as represented at
Figures 1 and 2 the container presents to view a large open mouth into which to
pour the lamp oil conveniently; the combined lid and burner when lowered into
position would by the action of the flange against the vertical wall n of container
be supported in a truly vertical position so that the male screw j would make
connection with the internal screw m without crosswinding.
k
The periphical edge of lid can in some cases be made to screw over the container
in such cases the internal screw would be formed on the lid as shewn at o Figure 3
and the external screw would be formed on the container as shewn at p Figure 4
the internal periphical vertical wall q passing over the external periphical wall »
and thus guiding and supporting the lid Figure 3 in a truly vertical position over
the container Figure 4 so that the lower threads of internal screw o would make a
mechanically perfect connection with the external thread thus preventing
crosswinding.
The internal screw o of lid as shewn at Figure 3 can in some cases be formed
to take on to an external screw thread formed on the outer surface of container at
which will be readily understood without further drawings.
For convenience in fixing the containers to stands we in some cases provide the

page_text: pin which would be secured to the lamp stand by means of a suitable nut after
the container had been connected to the stand by means of the ordinary plug
screw u.
In other cases we provide a metal casting as shewn in section at v such metal
casting being provided with a square shaped recess so that a pin w on which
would be forined a square part would take into the recess provided to receive it
so that when a nut is passed onto the screwed end of the pin w such pin would
be held in position to receive the locking nut.
We do not claim the use of any particular class of burner, as we can select
any suitable burner and combine it with or form on it our new parts, namely-
the collar bor k and the parallel screw d or j as shown at Figure 5 of first
modification, in a like manner the burner part represented at Figure 1 beyond the
line y is old and we do not claim it excepting when incorporated with the lower
parts h. k. and j.
The lower parts
and of Figure 1 can be produced out of sheet metal by
the spinning process in other cases when expense is no object we prefer to use
rings of cast metal.
The parts and n of Figure 2 are shewn as produced by the spinning process
but we prefer in some cases to form such parts out of cast metal and in a like
manner the parts bd and a e of Figures 5 and 6 can be formed out of cast
metal by the spinning process.
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
1st. The making of a lamp container by the utilization of any ordinary oil
container made out of metal, glass, or other suitable material such container being
provided with new parts consisting of a vertical thimble part in conjunction with a
parallel internally screwed socket as shewn at a and e Figure 6.
2nd. The making of a lamp burner by the utilization of any ordinary burner on
the shank end of which is formed new parts consisting of a guiding collar in
conjunction with a screwed plug as illustrated and described in reference to
Figure 5.
3rd. The making of a lamp container of new and original construction consisting
of a container provided with a large open mouth taking connection with a burner
and lid combined in one piece, the lid being provided with a vertical periphical
guide collar situated over an external screw thread such guide collar taking into an
internal periphical guide collar provided in the open mouth of container over the
internal screwed passage thereof so that the guide collar of the lid will guide the
external screw thread of such lid into a truly vertical position within the container
to enable the external threads formed on the lid to make mechanically perfect
connection with the internal threads formed in the mouth of container as illustrated
and described in reference to Figures 1 & 2.
4th. The making of a lamp with a lid and burner combined the lid taking over
or on to the container as illustrated and described in reference to Figures 3 and 4.
5th. The making of a lamp with a lid and burner combined the lid taking over
or on to the extreme outer periphery of container, as illustrated and described in
reference to Figure 4.
