PROVISIONAL SP
An Improvement connected with Cycle and other Oil Lamps,
I, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improvement connected with cycle and other oil
lamps, the object being that a cyclist, a coachman, or other person can see at a
glance the quantity of oil he has in the "well," and by a gauge on the face of an
appliance affixable to said "well" the length of time the lamp can be kept
alight.
For the purpose of my invention, I construct by stamping or otherwise a
rectangular shaped metal case of two sides and ends, an open back with clip ears
and a slotted front. I cement a glass within this case and press the cement and
glass into close contact with the casing by a liner which is also slotted like the face
of the casing.
I fix this appliance on or within the wall of the ordinary metallic oil well of a
lamp with a communication between them, so that the height of the oil in the
"well" can be seen through the glass of the casing.
I mark the outer face of the casing with numerals say 2, 4, 6 etc. as representing
the number of hours for which the wick can be kept burning, the oil line seen
through the glass also indicating its height.
I prefer to affix a tube nozzle on the appliance as a filling hole and close it by
a screw nut or a flap.
By this means the "well" can be filled from the outside and the quantity seen
as being poured in, without opening the door or otherwise interfering with the oil
"well" for removal and refilling as at present.

1, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp 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 :-
This invention relates to an improvement connected with cycle and other oil
lamps, the object being that a cyclist, a coachman, or other person can see at a
glance the quantity of oil he has in the "well," and by a gauge on the face of an
appliance affixable to said "well" the length of time the lamp can be kept
alight.

page_text: My invention will be clearly understood by a reference to the annexed drawings
in which at Figure 1 I show detail views of my appliance. Figures 2 and 3 are a
side view and front view respectively of the appliance in position on an oil "well"
of a cycle lamp but it is applicable to all kinds of oil lamps such as those used by
carriages and other vehicles.
For the purpose of my invention, I construct by stamping or otherwise a
rectangular shaped metal case A of two sides and ends, an open back with clip ears B,
and a slotted front. I cement a glass C within this case A and press the cement and
glass into close contact with the casing A by a liner E which is also slotted like
the face of the casing and is forced home and held by the turning in of the lips B
to unite the three parts together perfectly liquid tight. This combination of sight
appliance for a lamp "well" may if provided with a backing be attached to an oil
"well" of a lamp at its upper and lower parts only but I prefer to shape it to the
outside formation of an oil "well" and solder it along the edges. The frame or
liner EI prefer should be a reflecting medium, so that when the light shines through
the prism the height of the oil in the tank may be seen more prominently.
I fix this appliance on or within the wall of the ordinary oil "well" F of a lamp
with a communication between them so that the height of the oil in the "well"
can be seen through the glass of the casing. I mark the outer face of the casing
with numerals, say, 3, 6, 9, 12 as representing the number of hours for which the
wick can be kept burning, the oil line seen through the glass also indicating its
height.
I prefer to affix a tube nozzle G on the appliance as a filling hole and close it
by a screw nut H or a flap.
By this means the "well" can be filled from the outside and the quantity seen
as being poured in without opening the door or otherwise interfering with the oil
"well" for removal and refilling, as at present.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The apparatus shown at Figure 1 carrying an exposed prism, and attachable to
a lamp tank or oil "well" as and for the purposes described.
