Improvements in Lamps.
I PETER ROBERTSON of number 454 Collins Street in the City of Melbourne
Victoria Australia Marine Engineer 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 improvements in oil and spirit lamps and is chiefly
applicable to that class known as engineers' or ships' hand lamps and has been
devised principally to render them unspillable (and so obviate the loss of oil spirit
or other liquid used) when accidentally upset and also to afford an easy and con-
venient method of, and appliance for, trimming the wick and keeping the latter
from falling back into the lamp. The lamp is provided with four handles made of a
convenient form as hereafter described.
The invention consists as follows :-
The lamp well is made in the ordinary taper shape and furnished with the usual
handle and spout.
In this spout are secured two jaws (or equivalents) which grip
the wick rendering it impossible for it to return into the lamp.
To the side of the lamp well are soldered lugs to which the hooked ends of the
vertical wire handle are attached hingewise.
This wire handle extends in an upward and graceful manner terminating in a
hook or curved shape for convenience of holding. To a junction of this handle
is attached a spring rod which proceeds into the cover of the lamp at this said
junction is affixed a spring catch for holding a pricker. This pricker is made of
bent wire and torminates in sharpened points for adjusting the wick-the pricker
is so arranged that it can freely play about but not become detached from the
vertical handle or rod. The said rod enters the lamp cover and rests in an oval
space formed therein and when it is desired to remove the cover this rod is pulled
towards the deeper side of the oval space and simultaneously the cover is pushed
upwards on the rod.
Reference may now be had to the accompanying drawings in which
Figures 1 and 2 are side and front elevations respectively of the lamp while
Figure 3 is a section of the cover showing the releasing construction of same.
The dotted lines in Figure 1 show the cover released and the lamp open for
filling and in this figure the spout is shown in section.
In these figures A is the lamp, A' the spout in which latter are jaws A³ for
gripping the wick A and allowing it to proceed outwards but not backwards, these
jaws (A) are secured at A in such a manner that a springy nature is imparted to
them and they extend almost the full length of spout A' and are of a similar
section to the latter.
Bis the cover in which are formed the oval space B' (for releasing same) and
the inverted pipe space B which is occupied by rod C when cover B is released.
D is the bent handle made of wire and in two pieces, the side handles D' and D'
terminate in hooks D³ hinged at D' said hinges being soldered to the lamp A.
On the cover B are provided staples to hold the handles D' and D². The
pricker E is conveniently held on the rod C by the spring catch E'. F is the
auxiliary handle.
I do not confine myself to any particular size exact shape or materials of
construction but the invention (as illustrated) I find to be satisfactory.
The mode of using this invention is as follows:-Upon pulling the rod C
towards the deep side of the oval space B₁ the cover B is released and then pushed
upwards on said rod the former being allowed to do so by the end of the rod C
occupying the space B' therein thus causing the cover to become mechanically

hinges D the lamp is then filled in the usual manner the wick A is threaded
through the jaws Aby a wire. (sufficient. being left protruding for ignition). To
close the lamp the handle D is brought to a vertical position, the rod C is pushed
reversely to that before described and the cover B pressed firmly on the neck of
the lamp. When the wick requires adjusting the pricker E is taken off the spring
catch E and used for the purpose. It will thus be seen that the lamp, by the
peculiar construction of cover B, is unspillable and can be held or hung in any
required manner by handles D D' D' and F making it specially valuable for use on
ships, public works, and for general purposes.
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 :-
H
1. In lamps The peculiar cover (as B) in combination with the central spring
rod, C on which it works said rod being fixed to a handle of a bent form substan-
tially as herein described and as illustrated in the accompanying drawings.
2. In lamps-A spout having jaws as (A) therein or other equivalents so as
to grip the wick in such manner that the wick can be pulled outwards and so
retained but cannot fall by its own weight into the lamp substantially as herein
described and as illustrated in the accompanying drawings.
3. In lamps: A handle (as D) fixed to a lamp made so that three or more
bends are obtained for use as handles in combination with the herein before described
lamp substantially as herein described, and as illustrated in the accompanying
drawings.
4. In lamps-A bent wire pricker (such as E) placed as at E' for regulating a
wick in combination with the herein described lamp substantially as herein
described and as illustrated in the accompanying drawings.
5. In lamps -The peculiar construction arrangement and combination of all
the parts to form a lamp substantially as herein described and as illustrated in the
accompanying drawings.
