I, JOHN SANDERS of 3 St. John's Gardens, Queens Crescent, Haverstock Hill
N.W. Tin Plate Worker, 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 has reference to that class of illuminating device known as oil
chandeliers, in which the oil is supplied from a central container or reservoir to a
number of burners, the chandelier being suspended and capable of ready adjustment
by a telescopic arrangement similar to that employed in the case of ordinary gas
chandeliers; and is especially desired to avoid the risk of accident by explosion
arising from the oil coming into contact with the light of the burners should the
chandelier be upset or caused to assume any other than its normal vertical
position.
In the accompanying drawings, Figure lis a sectional elevational view of the apparatus
constructed in accordance with my invention. Figure 2 is a detached end view, and
Figure 3 a cross sectional plan taken on line A B Figure 1, showing more particularly
the guide plate hereinafter described which I employ; and Figures 4 and 5 represent
a plan and end view respectively of a modification to be hereinafter described. Said.
apparatus comprises a central container or reservoir A, supplying a series of smaller
receptacles B with oil-for feeding the wicks of the burners-through the tubes or
conduits C, extending radially from the reservoir or container A. The latter is
charged with oil at a suitable opening closed by a screwed cap a, and provided with a.
cover b of any appropriate ornamental design. The height of the reservoir A is so
determined that when the latter is filled, the level of the oil will be such as not to allow.
the latter to come into contact with the burners fitted in the receptacles B.
Air is admitted to the interior of the reservoir by means of a coiled or spiral
tube D so disposed within the reservoir A that in the event of the apparatus

page_text: being upset no oil will escape from the interior..of the reservoir. I prefer to
construct the receptacles for containing the oil to supply the wicks of the burners
similarly to those described in the specification of my Patent of prior date hereto
No. 17,75588, comprising a tapering cylinder closed at the lower end by a screwed
cap, the upper portion thereof terminating in an annular chamber E. a small
cylinder F being furnished to receive the screwed end of the burner, and a short
tube c provided to allow of the escape of any foul air or gas which may accumu-
late, serving also to facilitate combustion. The radial supply tubes or conduits C
aforesaid are cut away at their inner ends and perforated with apertures as shown
in Figure 1 to allow of the free passage therethrough of the oil contained within
the chamber or reservoir A aforesaid.
The means which I adopt for automatically shutting off the supply of oil or other
illuminant to the receptacles B in the event of the chandelier being upset or
assuming any other than its nominal vertical position, is as follows:-
Within the reservoir A I suspend from suitable supports at d, vertical rods e
having weights attached to the lower ends thereof.
-
Within the discharge orifices of the radial tubes or conduits Care arranged
valves G, swivelled or otherwise loosely attached to the horizontal rods working
within said tubes C, the opposite ends of the rods last referred to being cranked
and formed with elongations or loops H (shown more particularly at Figure 2
and in dotted lines Figure 3.) to which the lower ends of the vertical rods are
attached being capable of free sliding movement from side to side thereupon.
A guide plate I, Figure 3, is disposed within the reservoir A, and formed
with V shaped curs, indentations or openings for the reception of the vertical
weighted rods e aforesaid. The action of this guide plate 1 is as follows:-
Supposing the chandelier to be inclined from J to K Figure 3 J being the
highest part, the vertical weighted rod e. at the lower end K falls, and by a direct
thrust closes the orifice, by means of the valve Gadisposed at the end of the
cranked rod g, in the tube C; and the vertical weighted rod eat the higher end
dropping back into the V shaped opening withdraws the valve from the higher
orifice thus allowing all the oil to flow from its receptacle B: Whilst those rods
at the sides falling by the action of the chandelier travel along one side of the
V shaped inclines and in so doing force outwards the valves G disposed on roils g
at; the ends of those conduits thus preventing any further. access of oil whilst the
chandelier maintains such inclined position.
I
In lieu of the circular guide plate I, formed with openings or indentations
therein as last above described, I may substitute therefor a square guide plate-
when employing four radial supply tubes or conduits C-upon the edges of which'
the vertical weighted rods e would be capable of sliding freely side to side.
use in conjunction with said guide plate last mentioned a curved elongation or
loop H formed upon the cranked end of the horizontal rod g as shown, in
Figures 4 and 5 (which represent a plan and end view respectively of the curved
elongation or loop H' of the horizontal rod g and attachments) by which means, the
side to side movement of the weighted vertical rods will tend to close the outlet orifices
in the supply tubes or conduits C
'rom the foregoing it will be seen that in the event of the chandelier being upset or
assuming an inclined position, the oil contained within the receptacles B cannot come
into contact with the light of the burner but will be received within the annular
chamber or receptacle E-surrounding the burner tube F, the further supply from the
reservoir being automatically shut off by the valves Gactuated in the manner herein
before described.
iThe automatic controlling-device-according to my Invention may be readily adapted
to oil brackets and pendants to ensure safety to same when fitted at a 'height which
would necessitate their removal for filling with oil for cleaning or otherwise; the flow
of oils from the reservoir to the receptacle containing the supply for feeding the wick
of the burner being then automatically shut off and regulated as herein before described
in the case of oil chandeliers

page_text: 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 :-
First: The method of and means employed for automatically governing the supply
of illuminant from the central container or reservoir A to the receptacles B for feeding
the burners, substantially as herein described and shown in the accompanying
drawings.
Second: The combination of parts comprising the receptacles B for containing the
oil supply for feeding the burners, substantially as herein described and shown.
Third: The employment of a coiled or spiral tube D for admitting a supply of
external air to the interior of the reservoir substantially as herein described.
