PROVISIONAL SPECIFICATION.
Improvements in and relating to Street Lamps.
I, ALEXANDER MACKENZIE, of 29, Clyde Place, in the County of the City of
Glasgow, Watchman, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to improvements in and relating to street iamps,
and particularly those used as danger lamps, where oil is burned.
According to my improvements 1 fit a vertical division or partition in the verti-
cal wick tube of burner so as to have two wicks working parallel, and I solder
the annular collar to outside of oil holder for the burner to screw into, and so be
isolated from heat.
The wick would be regulated or raised and lowered from outside the rear of
lamp, without requiring to open the door. This would or may be effected by a rod
with washer or disc near end, which would turn a wheel on the wick regulating
spindle, and a pointed end on this rod could trim the wick.
The top or roof of lamp would be closed, and perforated plates would be fitted
round lamp, and have slides working over these perforations to open or close the
lamp for ventilation and passage of air, while a circular perforated disc would be
fitted at base of lamp to work over a perforated plate, and regulate the air supply
to lamp.

Improvements in and relating to Street Lamps,
I, ALEXANDER MACKENZIE, of 29, Clyde Place, in the County of the City of
Glasgow, Watchman, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement, reference being made to the accompanying
drawing, that is to say: -
This invention has reference to improvements in and relating to street lamps,
and particularly those used as danger lamps, where oil is burned.
And in order that my said invention and the manner of carrying same into prac-
tice may be properly understood, I have hereunto appended a sheet of explanatory
drawing, in which the same reference letters are used to indicate corresponding parts
in all the figures where shown, Figure 1 is a sectional elevation of a four sided

page_text: street or danger lamp as fitted with my improvements. Figure 2 is a view of
the burner and oil vessel as detached from the lamp; while Figure 3 is a view
corresponding to Figure 1, of a triangular configuration of lamp as fitted with
my improvements.
Referring to these drawings:-
According to my improvements I solder the annular collar a to outside of oil
holder a¹ for the burner b to screw into, and so be isolated from heat while an
inclined face a is formed at lower part of collar for all the oil to flow into the
holder or reservoir a¹.
The wick is regulated, or raised and lowered from outside the rear of lamp,
without requiring to open the door. This is effected by a rod c with washer or
disc c near end, which turns a wheel on the wick regulating spindle d, and a
pointed end on this rod c is used to trim the wick z.
The top A¹ of roof A of lamp is closed, and perforated plates e are fitted round
lamp, and have slides e¹ working over these perforations e to open or close the
lamp for ventilation and passage of air; while a circular perforated disc f is fitted
at base of lamp to work over a perforated plate f and regulate the air supply to
lamp.
The top of wick tube is preferably formed of an undulating shape as shown
in Figures 2 and 3 to lessen the formation of smoke, and give a higher illuminat-
ing light.
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:-
4
First. In lamps, the method of isolating the burner from the oil vessel substan-
tially as herein described in reference to and shown in the accompanying drawing.
Second. In lamps, the method of regulating the wick without requiring to open
the door consisting in the use of a rod with disc to turn a wheel on the wick
regulating spindle, substantially as set forth.
Third. In lamps, the ventilating and regulating of the air supply by perforated
plates, and sliding or turning covers, substantially as herein described in reference
to and shown in the accompanying drawing.
Fourth. The arrangement and combination of the parts of lamps, substantially
as herein described in reference to and shown in the accompanying drawing.
