plug having a valve seat. A valve is adapted to fit on this, seat, and, the, valve.has
a pendant operating pin which passes through an opening in the plug. The valve
also has an upwardly projecting guide pin around which is coiled a spring,,said
spring being held in contact with the valves by a suitable. looking pin or device so
that the spring is adapted to closer the valve quickly and hold the same upon its
seat with firinness.

Around the pendant vertical part of the supply pipe is fitted a collar, on which
bears a coil spring. The lamp reservoir is provided. on its upper portion with an
upwardly projecting neck which extends, over the lower, ond of the pendant
vertical supply pipe and reaches over the spring last mentioned. Above this neck
of the lamp reservoir is arranged a, cullar, which loosely surrounds the, pendant
vertical position of the supply pipe and this loose collar is screw, threaded externally
to enable it to be screwed into the upper threaded end of the neck of. the. lamp
reservoir, so that, the lower end of the loose collar rests upon the uppen end of the
spring for adjusting the latter to the required tension..
The lamp reservoir has one or more fiorizontal feed, pipes, upon the outer end, of
which are secured lamps of any suitabile construction.

I, JOHN STANLEY ROBLIN, residing at 306 John Street, West Bay City, in
the County of Bay, and State of Michigan, one of the United States of America,
Gentleman, do hereby declare the nature of this invention and in what mauner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
'41'
This invention relates to improvements in apparatus for lighting buildings with
oil, and pertains more especially to that class of lighting apparatus in which a
reservoir for the oil is used in connection with pipes leading therefrom to different
lamps throughout the building, and the invention consists in the arrangement and
combination of the several parts or elements used in the construction of the
apparatus and in the action and operation of the same, as I shall hereinafter fully
describe and which will also be mentioned and pointed out in the claims of this
Specification.
In the accompanying drawings my invention will be found illustrated.
Figure 1, represents a vertical section of my improved apparatus, Fig. 2, is the
same arranged for lowering the lamps for trimming, &c.
Figs. 3 and 4, are modified forms of a portion of Fig. 1', in elevation, and
detached.
1, represents a tank for containing a supply of oil, and this tank is located in an
elevated position at any convenient height above the device for burning the oil.
2, is a supply pipe with its upper end connected with the tnok and is preferably
extended into the tank for a short distance above the bottom and is provided with
a straiuing cup 3, containing cotton or other fibrous material 4, for retaining any
particles of dust, &c., contained in the oil. From the tank this pipe is led to any
convenient point in a building, and is arranged preferably so that its lower end
portions 5, depend from the ceiling of the room to be lighted to a suitable distance
and its lower end opening 7, is provided with a plug 8, containing a central
opening 9, and also a valve seat 10, on its upper end within the pipe.
Upon the valve seat 10, is arranged a valve 11, provided with a downwardly
extending operating pin 12; passing through the opening 9, and projecting below
the plug, and has also an upwardly projecting guide pin 13, around which a
spring 14, is coiled and above the spring a pin 15, is passed through the pipe and
serves to retain the spring in contact with the valve for quickly closing and retaining
the same upon its seat with firmness and reliability.
Around the lower end of the supply pipe is arranged a collar 16, and above
this collar and with its lower end resting on the same is a coiled spring 17,
18, is a lamp reservoir, and is provided on its upper portion with an upwardly
projecting neck 19, which extends over the lower end of the supply pipe and
reaches over the spring, and 20, is a collar loosely surrounding the supply pipe
and has its outer periphery provided with a screw threaded which is passed into
the upper threaded end of the neck 19, so that its lower end rests upon the upper
end of the spring 17; for adjusting the spring to the required tension for a
purpose to be presently explained. Connected with the lower portion of the
reservoir 18, are one or more laterally extending feed pipes 21, upon the upper
end of which are secured in any convenient manner, the lamps 22, of any common
or desirable form containing a wick, burner or chimney in the usual form.
The collar 20, is turned to lift the reservoir and lamps, and also the contents of
the reservoir when partially filled, to a position to bring the bottom 23, of the
"
....

page_text: reservoir nearly to contact with the lower end of the operating pin 12, and the
lamps then being lighted, the oil in the reservoir flows thereto and is consumed
until the weight of the contents of the reservoir is reduced sufficiently to allow
the spring 17, to lift the reservoir, to bring its bottom 23, in contact with the
operating pin 12, and move the valve from its seat, the oil from the supply tank
then flows through the pipe, and replenishes the contents of the reservoir until its
weight is sufficient to move the same downwardly when the valve again closes and
the consumption of oil again reduces the weight of the contents in the reservoir
and the valve is again operated the main level of the contents of the reservoir
being thereby maintained by an automatic action the tendency of the action being
that, when the lights are burning and the tension of spring 17; properly adjusted,
the reservoir is held to a position to allow the required flow of oil through the
valve without perceptible variation, and as soon as the lights are shut off the oil
flows into the reservoir until its contents are of sufficient weight to move the
reservoir away from the piu and the valve then closing, retains the oil above
the valve until the lamps are again lighted. It will be noticed that the reservoir 18,
and also the supply tank 1 are both open to atmospheric pressure, and as regards
the supply tank its location and height is a matter of convenience as the valve
automatically operated by the weight of the contents of the lamp reservoir,
efficiently and positively control the supply of oil to the reservoir as shown in Fig. 2,
the portion 5, of the supply pipe is provided with an outor casing or covering
tube 24, and this casing tube is held in position by cords 25, passed over pulleys 26,
carried by the ceiling or other permanent support, one end of the cords being
secured to the casing while balancing weights 27, are secured to the opposite
ends.
With this construction the collar 16, is secured upon the lower end of the
casing tube and the spring 17, rests on the collar, and the reservoir and the screw
collar 20, is then arranged to operate in the same manner as before described, the
casing tube being held firmly in position by the weights, the operation of the
reservoir upou the guide pin for regulating the oil supply operating in the same
manner as before described and by this construction the reservoir can be lowered
for trimming and lighting the lamps, the tube 24, passing downwardly over the
portion 5, with the weights moving upwardly, the valve of course being closed so
that no oil can pass out until the casing tube is again moved up to its normal
position.
Of course it will be understood that the most important feature of the invention
is the means for automatically operating the valve to provide a proper oil supply
for the reservoir, and it will be understood that while I have described and
illustrated a spring for sustaining the reservoir and its contents in proper position
in relation to the valve, other means however, can be used and produce the same
effect, and in Fig. 3; cords pulleys and weights are used, while with Fig. 4, a
weighted lever is shown for the same purpose, so that I do not therefore limit
my invention to the precise construction and means herein described and shown for
accomplishing this purpose and wish it understood that while I have illustrated and
described a spring for holding the valve upon its sout, I am well aware that this
spring is not altogether required, as the weight and action of the downwardly
moving oil in contact with the valve has substantially the same effect, and the
spring is added as an additional means of securing a positive action of the valve
against liability of sticking and allowing a leak to occur.
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,.
