Improvements relating to Buoy Lamps, Anchor Lights, and the like.
I, WILLIAM THOMAS PARROTT, of Harrow House, Harrow Street, Hessle Road,
Hull, Lamp and Compass Maker, 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 consists of improvements relating to buoy lamps, anchor lights,
and the like, my object being to so construct such lamps as to render them more
effective and durable in service.
In order that my invention and the carrying of the same into effect may be the
more readily understood I append hereunto three sheets of explanatory drawings
to be hereinafter referred to.
On Sheet 1 Figure 1 is a front elevation, and on Sheet 2 Figure 2 is a sectional
elevation of a lamp constructed in accordance with my invention.
On Sheet 3 Figure 3 is an elevation and Figure 4 a plan showing my improved
means for raising and lowering the wick.
The same reference letters in the different views indicate the same parts.
The upper part of the lamp is hinged to the oil vessel forming the base A,
and a projecting bracket as B from the body or upper part (on the opposite side to
the hinge joint) is caused to engage with the stud A¹ on the base or oil vessel.
By screwing on the nut A³ (connected by a chain with the lamp base) the upper
part of the lamp is pressed down upon the india-rubber ring or washer C and thus
a secure and watertight joint is formed between the two parts. On completely
unscrewing the nut A2 the upper part of the lamp can be turned back on its
hinge to permit of access to the burner in the ordinary manner.
The burner D affixed to the base or oil vessel receives the necessary supply of air
from the upper part of the lamp, such supply passing through the tubular guards E
(preferably four in number). But instead of such air blowing directly through to
the burner, in the usual manner I so arrange compound passages or conduits
within the tubes E that the air is compelled to take a circuitous course through
the same as illustrated by the arrows in the sectional view at Figure 2. The air
is admitted within the upper part of the lamp through the gauze covered annular
aperture G and passes into the inner trunk H and from thence to the tubes E.
Baffle plates as J are arranged at the mouth or inlet end of each of the tubes E
to assist in the prevention of too great a rush of air to the burners.
The cap or lid K is hinged to the top of the lamp and is secured when closed
by the thumb nut L, and screwed stud L', the latter being fixed to the upper part
of the lamp body. The cap is ventilated by the provision of a gauze covered
annular aperture near the lower part of it, and perforations at its upper portion
as shown. I also fit a gauze top as M¹ on the chimney part M of the lamp body.
Instead of affixing to the outer end of the wick operating spindle as N the
ordinary finger piece for effecting the necessary rotation of such spindle, I employ
a small toothed wheel as on the outer end of the spindle which gears with a
pinion P on the inner end of the stem of the finger piece P which is mounted

page_text: in the lower part of the lamp body. On opening the lamp by turning back the
body part on its hinged joint the pinion P is drawn out of gear as it moves with
the lamp body, but is again put into gear on the closing of the lamp. By
arranging the wick operating finger piece upon the lamp body as described I am
enabled to avoid the weakening of the lower part of such body by the provision
of a slot or gap therein to enable it to pass over the wick operating spindle, as is
necessary when the finger piece is affixed directly to such spindle in the ordinary
manner.
To ventilate the oil vessel A. forming the base of the lamp I arrange a small
pipe or tube Q as shown, providing it with a tap or cock as Q¹ and a disconnecting
union as Q to permit of the movement of the upper part of the tube with the
lamp body.
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:-
1. Buoy lamps, anchor lights, and the like, constructed substantially as
described and as illustrated.
2. In buoy lamps, anchor lights, and the like, the arrangement of circuitous
passages or conduits between the air admission aperture G and the burner D sub-
stantially as described and as illustrated.
3. In buoy lamps, anchor lights, and the like, the improved arrangement and
combination of parts for the operation of the wick substantially as described
and as illustrated.
