Year: 1885

page_text: We, HENRY TROTTER of Bute Road, Cardiff, in the County of Glamorgan, Ship
Store Merchant, and GEORGE FIELD of Moseley Street, Birmingham, in the County
of Warwick, Commercial Traveller do hereby declare the nature of said invention
for "IMPROVEMENTS IN SHIP SALOON, AND OTHER LAMPS FOR VARIOUS PURPOSES,"
to be as follows:-
Ship saloon and such like pendant lamps of the ordinary construction, are so
arranged that the rays of light given out from the burner, are interrupted by
opaque objects which cast shadows; and our said invention relates to means
whereby such lamps are rendered shadowless; that is to say, the parts of the lamp
are so arranged that the luminous rays of light proceeding from the burner of a
lamp are not intercepted or interrupted by reservoir or other parts, therefore the
lamp becomes shadowless.
We will describe our invention in connection with a ship saloon lamp for burning
paraffin or other like hydro-carbon oil.
The burner and wick bolder which forms the middle of the lamp is surrounded
by a concentric oil container or oil reservoir in the form of an annulus or hollow
ring, situated at a considerable distance from the burner, this tubular aunulas or
hollow ring, which is preferably circular in cross section, is suspended by three or
other number of supporting rods connected at their upper ends to a mount or boss
provided with a hook or ring by which the lamp is hung-The burner and wick
holder which is situated in about the same plane as the annulas, is supported by
radial feeder tubes, converging from the tubular ring reservoir, to the centre of the
lamp, or to the wick holder in the direction of radii-The position of the wick
holder is such, that the oil is fed thereto automatically from the fact of the oil
in the container being on the same level as the oil should be in the wick holder,
therefore oil is always kept up to the wicks and at a constant level or nearly so.
The feed tubes leading from the oil container are bent to a little below the level
of the container itself-A suitable shade is supported by brackets within the tripod
suspending rods above the burner-An ordinary bell or heat deflector is suspended
above the mouth of the shade.

page_text: The oil annulas or container is made preferably circular in cross section, although
it may be made elliptical, angular or lozenge shaped-When angular, the angles
are disposed in the direction of the rays of light emitted from the lamp-The
container is fashioned from a piece of tubing bent into a complete circle or belt.
The oil is supplied to the oil container or reservoir through a screw cap; so that
when the container is full and the lamp burning, the oil flows to the wicks through
the radial feeders which keep the oil always at a constant level, while the arrange-
ment of parts constituting the lamp, renders the said lamp shadowless.
Although we have only described our invention as applied to a ship saloon lamp,
yet our said improvements may be applied with like effect to other forms of lamps
for various purposes.

Purposes.
We, HENRY TROTTER of Bute Road Cardiff, in the County of Glamorgan, Ship-
store Merchant and GEORGE FIELD of Moseley Street Birmingham in the County
of Warwick Commercial Traveller, do hereby declare the nature of said invention
for IMPROVEMENTS IN SHIP SALOON, AND OTHER LAMPS FOR VARIOUS PURPOSES,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Ship saloon and such like pendant lamps of the ordinary construction, are so
arranged that the rays of light given out from the burner, are interrupted by
opaquo objects which cast shadows; and our said invention relates to means
whereby such lamps are rendered shadowless; that is to say, the parts of the lamp
are so arranged that the luminous rays of light proceeding from the burner of a
lamp, are not intercepted or interrupted by reservoir or other parts therefore the
lamp becomes shadowless.
We will describe our invention in connection with a ship saloon lamp for burning
paraffin or other like hydro-carbon oil.
The burner and wick holder which form the middle of the lamp is surrounded
by a concentric oil container or oil reservoir in the form of an annulas or hollow
ring, situated at a considerable distance from the burner, this tubular annulas or
hollow ring, which is preferably circular in cross section, is suspended by three or
other number of supporting rods connected at their upper ends to a mount or boss
provided with a hook or ring by which the lamp is hung. The burner and wick
holder which is situated in about the same plane as the annulas, is supported by
radial feeder tubes, converging from the tubular ring reservoir, to the centre of the
lamp, or to the wick holder in the direction of radii. The position of the wick
holder is such, that the oil is fed thereto automatically from the fact of the oil in
the container being on the same level as the oil should be in the wick holder,
therefore oil is always kept up to the wicks and at a constant level or nearly so.
The feed tubes leading from the oil container are bent or directed. to a little
below the level of the container itself. A suitable shade is supported by brackets
within the tripod suspending rods above the burner. An ordinary bell or heat
deflector is suspended above the mouth of the shade.
The oil annulas or container is made preferably circular in cross section, although
it may be made elliptical, angular or lozenge shaped. When angular, the angles
are disposed in the direction of the rays of light emitted from the lamp. The
container is fashioned from a piece of tubing bent into a complete circle or belt.
The oil is supplied to the oil container or reservoir through a screw cap; and
when the container is full, and the lamp burning, the oil flows to the wicks
through the radial feeders which keep the oil always at a constant level, while the
arrangement of parts constituting the lamp, renders the said lamp shadowless.
Although we have only described our invention as applied to a ship saloon lamp,
yet our said improvements may be applied with like effect to other forms of lamps
for various purposes.

page_text: We will now proceed to describe with reference to the accompanying drawings
the manner in which the same is to be performed.
Figure 1 is a side elevation of a ship saloon lamp, constructed according to our
invention. Figure 2 is a transverse vertical section of the lower part of the said
lamp, showing how the oil from the ring like reservoir is fed to the wick holder,
which latter forms the middle of the lamp, and situated underneath the burner.
Figure 3 is a plan of the underside of figure 1, with the wick holder, and the feed
tubes partly in section.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the oil reservoir, consisting of an annulas or hollow ring, wherein oil for the
feeding of the lamp is stored. Oil is replenished to the said ring reservoir through
the cup opening a³ best seen in figure 1. The cross section of the oil container is
best seen in figure 2-This concentric oil reservoir is suspended by supporting
rods b, connected at their upper ends to a mount or boss be provided with a hook
or ring b³, by which the lamp is hung when suspended. c is the burner of the
lamp, and d the wick holder disposed in the middle of, or forming the centre of
the lamp, and surrounded by the oil reservoir; which said wick holder with
burner, is supported by radial feeder tubes e e e converging from the oil reservoir
to the centre of the lamp; or rather converging to the wick holder in the direction
of radii.
The position of the wick holder b with respect to the oil reservoir a is such, that
oil from the said reservoir is conveyed through the feed tubes automatically in
consequence of the oil container a being higher level than the lower part of the
wick holder b, therefore oil is always kept up to the wicks f, and at a constant
level or nearly so; that is, the oil in the wick holder will always remain at the
same level as the oil in the reservoir.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. Making the oil reservoirs of lamps, annular, or in the form of a hollow
ring, wherein oil is stored for supplying the burner of the lamp with oil; which
said hollow ring surrounds the wick holder and burner in the form of a belt in
which the wick holder is situated in the middle thereof; the latter being fed from
the former by means of radiating hollow arms or tubes through which oil flows for
supplying the burner-The parts being constructed, arranged, and a shadowless or
nearly shadowless lamp thereby produced substantially as described and illustrated.
Secondly. A shadowless or nearly shadowless lamp, consisting of a central wick
holder of a diameter less than that of the burner, the said holder being surrounded
at a distance by a hollow ring, or annulas wherein oil is stored and supplied
to the wick holder through radiating feed tubes, substantially as described and
illustrated.
