COMPLETE SPECIFICATION.
An Improved Combined Lamp and Oil Can.
I, HAROLD ASHWORTH, of Queen Street, Brisbane, Queensland, Share Broker,
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 :-
My invention relates to an Improved Combined Lamp and Oil Can and
comprises the improvements hereinafter set forth. I may use an oil lamp or an
electric lamp in combination with the oil can.
According to my invention when I use an oil lamp I arrange that the oil for the
lamp shall be supplied from the same container as the oil for lubrication.
An important feature of my invention relates to the provision of means for
cutting off the oil from the wick of the lamp when lubricating or feeding without
extinguishing the light.
In order that my invention may be clearly understood I will proceed to describe
the same with reference to the accompanying drawings, in which
Figure 1 is a side elevation of a combined oil lamp and oil can or feeder
constructed according to my invention.
Figure 2 is a longitudinal central section of the same, and
Figure 3 is an under plan view drawn to a larger scale.
Figure 4 illustrates my combined oil can and electric lamp.
Like letters denote similar parts in all the figures.
A is the oil container of any suitable shape and B is the handle thereof; C is
the lamp casing which is of the bull's eye pattern and the back of which is joined
to the handle B by a suitable stay C. Said stay has preferably a number of
perforations C to prevent the same being beated by the lamp to any great extent.
D is the spout of the oil can which is made with a joint D' so that nozzles of
different lengths may be attached if desired. Said spout is provided with a stop
valve E mounted on a spring E' which maintains the valve closed. Said valve is
connected by a link E' with a piece F loosely mounted on a shaft or rod F' secured
to the can. To the piece is connected a rod or springer G which passes up the
column of the handle and is furnished with a button G' at the top. By pressing
on the said button G' the valve is withdrawn from the opening leading to the
nozzle or spout and the oil is then free to flow out The oil container is filled
through the hole H when the screw plug H is removed.
The lamp casing C is separated from the oil container by a partition I through
which the wick tube 1' passes. Said wick tube extends nearly to the bottom of the
oil container. Below the wick tube I provide a fixed guide J, through which a plate
or slide J' is adapted to slide. Said guide is perforated at J2 to correspond with
similar perforations in the slide. When said perforations are in line with each
other (and only then) oil can gain access to the wick. The plate or slide J' is
attached to the link E' which actuates the valve E and is so arranged that when
the button G' is depressed to open the valve E for lubricating, the passages leading
to the wick tube are closed so that no more oil can gain access to the wick therein
whereby the drowning of the light is prevented when the can is inclined. After
the oil is cut off from the wick tube the light will continue to burn for several
minutes by reason of the oil contained in the tube. When the button G' is
released the passages to the wick tube are opened and the oil again refills said
tube.
Air holes C are provided in the lamp casing for supplying air to the flame.
K is the wind guard.

page_text: My improved combined oil-can and lamp greatly facilitates the oiling of
machinery at night and in dark places as one hand only is required to hold both
lamp and oil can thus leaving the other hand of the attendant free. When 1
construct the lamp for use in coal mines 1 form the wind guard of wire gauze and 1
cover the holes C in the lamp casing with wire gauze to avoid any risk of
explosion. This combined oil can and lamp is specially adapted for use on
locomotives, and where machinery is at work in dark places. When use the
electric light, I prefer to place the battery within the column of the handle and
pass the wires or conductors through the handle to the lamp as shown in Figure &
so arrange that when the button G is depressed the battery circuit is completed
and the light is obtained, and when the button is released the circuit is broken and
the light extinguished.
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. A combined oil can and lamp in which the oil for lubricating and for the
lamp is supplied from the same container, substantially as described.
2. Such a combined oil can and lamp provided with menus for cutting off the
supply of oil to the wick while lubricating, for the purpose specified.
3. An improved combined oil can and lamp constructed substantially as described
with reference to the accompanying drawings.
4. A combined oil can and electric lamp substantially as described.
