PROVISIONAL SPECIFICATION.
Improvements in or Additions to Ships' Signal Lamps and like
Lamps.
I, ELI HENRY GRIFFITHS, of Bradford Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows :—
This invention relates to improvements in or additions to ships signal lamps and
like lamps, and has for its object, a chimney raiser, or means for removing and
holding up the chimney from off the burner of the lamp, during the lighting of the
same, or the trimming of the wick or wicks, and my said invention consists in the
employment of a lifting arm fitted with a band for clipping the chimney which is
metal at the upper part and glass at the lower.
In carrying out one form of my improvements, I fit within the interior of the
shell or body part of the lamp, and at some distance above the burner, a chimney-
carrying arm, having between its two ends, the inner of which is jointed and the
other free to be lifted, a clip, band or attachment, either made in the form of an
encircling loop, or in the form of a half-hoop, attachedly connected to the metal
part of the chimney, so that on the lifting arm, whose inner end is jointed to a
bracket or the inside of the lamp, being raised by hand, the chimney is
taken from off the burner, which is made accessible for lighting and trimming
purposes.
The joint of the lifter may be made stiff, or have a ratchet affixed to it for
holding it and the chimney in a fixed position when lifted, so that a person both
trimming and attending to the lamp has both ends free.
Instead of the joint being at one end of the lifter beam or arm, it may be near
one end, and the short arm, in such a case, would form the handle, which, when
depressed, would lift the chimney.

Improvements in or Additions to Ships' Signal Lamps and like
Lamps.
1, ELI HENRY GRIFFITHS, of Bradford Street, in the City of Birmingham,
Manufacturer, 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 relates to improvements in chimney raisers for ships signal lamps
and like lamps, or to means for removing and holding up the chimney from off the
burner of the lamp, during the lighting of the same, or the trimming of the wick or
wicks, and my said invention consists in the employment of a lifting arm fitted with a
ring for clipping the chimney which is metal at the upper part and glass at the
lower.

page_text: In carrying out one form of my improvements, I fit within the interior of the
shell or body part of the lamp, and at some distance above the burner, a chimney-
carrying and raising arm, having between its two ends, the inner of which is jointed
and the other free to be lifted, a clip, band or attachment, either made in the form
of an encircling ring, or in the form of a half-hoop, attachedly connected to the
metal part of the chimney, so that on the lifting arın, whose inner end is jointed to
a bracket on the inside of the lamp, or to the inside of the lamp itself, being raise
by hand, the chimney is taken from off the burner, which is thus made accessible
for lighting and trimming purposes.
it may be near
Instead of the joint being at one end of the lifter beam or arm,
one end, and the short arm, in such a case, would form the handle, which, when
depressed, would lift the chimney.
It is understood that the chimney carrying and raising arm would fall into
position by its own weight, or would be pulled back by a spring.
Figure 1 of the accompanying drawing represents a ships' signal-lamp, provide
with a combined chimney carrying and raising arm made and fitted according to my
invention.
Figure 2 represents a cross section of the chimney part of the lamp upon the
dotted lines e Figure 1, looking downwards.
Figure 3 represents a front view of the joint part of the combined chimney-
carrying arm and lifter.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is the body of the lamp, having fitted within its interior, a burner b, provided
with a chimney c, with the lower part c', made of glass or some other transparent
material, and the other and upper part c², made of metal, and with the said upper
part connected to the lower part by ears or connections e³, whilst the said composite
chimney is raised, or both supported and raised by an arm d, jointed at d', to the
inside of the lamp or to a bracket of the lamp, and having a short arm or heel ²,
rear of it, having connected to it an end e¹, of a spring e, whose other end e³, is
secured to the upper part of the lamp's interior.
The raiser is cranked at its outer end ³, (which is supported by a stop f, carried
by the body of the lamp) and is terminated by an asbestos or other non-conducting
tip d', with which a persons hand comes into contact, when raising the chimney.
The said raiser has upon its middle part, a ring d', and its connection with the
chimney is made by hooked lugs d', engaging under a ring flange e, attached to the
metal part of the chimney, and having gaps c, within it, through which the hook
lugs of the ring take in connecting the chimney with, or disconnecting it from the
raiser.
C
The chimney is connected to the raiser in the following way :-Bring the gaps c,
within the ring ct, in the chimney coincident with the hook lugs de, at a time when
the raiser is in a lifted position, then push up the chimney and rotate the same until
the hooked ended lugs taking under the flange are brought up to the stops c.
To elevate the chimney, lift, the raiser, when the chimney will be removed from
the burner and assume a position-represented in dotted lines in Figure 1, and if the
same be lifted sufficiently high so as to bring the short arm d, beyond the joint,
then the combined chimney carrier and raiser, with the chimney, will be held in
their lifted positions.
Instead of bringing the arm or lever back by a spring, a counterpoise weight may
be employed for the purpose.
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:
:-
First. In ships' signal lamps and like lamps, a chimney raiser, or a combined
chimney raiser and carrier, consisting of an arm or lever jointed at one end and free
at the other end, substantially as described and set forth.

page_text: Secondly. In ships' signal lamps and like lamps, a chimney raiser, or a combined
chimney raiser and carrier, consisting of an arm or lever, jointed at one end and
free at the other end, drawn back, and retained, if desired, in a raised position by
the means and in the way substantially as described and set forth.
Thirdly. In ships' signal lamps and like lamps, the combination with a composite
chimney arranged and provided as described, of a chimney raiser, or a combined
chimney raiser and carrier, substantially as described and set forth.
Dated this 25th day of January 1895.
