COMPLETE SPECIFICATION.
Improvements in and connected with Lamps or Lanterns.
1, JOHN BROWNE of 10 Mildmay Road, Stoke Newington, in the County of London,
Engineer, 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 and connected with, Lamps or
Lanterns, and has for object so to construct such Lamps or Lanterns, that a great
brilliancy of light is obtained, capable even of piercing a very dense fog, without
increasing the consumption of the illuminant, whether gas, oil, or other illuminative
power is used.
In accordance with this Invention the lamp or lantern may be made of any
desired shape, either circular oval, square, hexagonal, or of any combination of
angles, and of any metal desired, and may be made so as to be conveniently carried
by hand, or so as to stand for street lighting, or so as to be capable of being hung
up in any position.
And in order that this Invention may be fully understood, I will describe same
with reference to the accompanying drawings and the letters and figures of reference
marked thereon, that is to say :-
Fig. 1 is a rear elevational view of a hand lamp or lantern, with enclosing door
shewn open. Fig. 1 is a sectional view of lamp top, and Fig. 1b is a view of a
ventilating plate. Fig. 2 is a sectional side elevational view of the same lamp or
lantern; and Fig. illustrates the lamp in side elevational view. These figures
describe the principles of the invention and the remaining figures illustrate its
adaptability to lamps or lanterns of various classes; for instance Fig. 4 shews the
same applied to a street lamp (in section) Fig. 5 to a bicycle lamp (in side view)
Fig. 6 to a ship's side light (in plan) and Fig. 7 a carriage lamp (in side view).
The applicability of the invention to all and every kind of lamp, will therefore be
apparent. Similar letters of reference indicate like parts in all the figures.
Now according to this Invention and in order to obtain an increased illuminating
power as aforesaid, I fit my lamps or lanterns with conical bulls eyes made of glass,
and with nickelled, enamelled, or other suitable reflectors.
In the drawings a a represent the conical bull's eyes and b b the reflectors aforesaid.
c is the gas or other flame, light or burner, the rays from which are reflected through
the glass bulls eyes upon the outside reflectors b from whence they are thrown
outwards. d is a perforated top to the lamp or lantern for consuming the smoke
and products of combustion passing through the lamp; e being the vent for hot air.
Wire gauze or perforated plates k, see Fig. 1" are inserted in convenient positions
within the lamp top d, say at d d². f is a perforated plate inside the lamp
controlling the air current.
The back of the lamp behind the flame may be made as a reflector to throw the
rays through the bulls eyes see g Fig. 1, or where it is desired to throw rays in 2 or
more directions and 2 or more burners are used in the one lamp, a central internal
reflecting ball (not shewn) may be employed. h Figs. 1 & 2 is a swinging bandle

page_text: attached to the lamp to render same readily portable. The handle may be conveniently
attached at its ends to the spindle i working in bearings formed in the walls of the
top tube & which spindle is capable of turning with the movements of the handle.
A spring clip fastening see Figs. 1 and 3 is preferably used to fasten the lamp
door when closed consisting of a suitably hinged plate or catch, taking over a
projection or spur upon lamp body or casing.
my
Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in and connected with lamps or lanterns, substantially as
herein before described and shewn in the drawings.
2. In lamps or lanterns the conical glass bulls eyes a and outer reflectors b in
combination with the perforated top d, & perforated plates f and k; all constructed
and arranged substantially as herein before described and shewn.
3. In lamps or lanterns the conical bulls eye glasses a, the nickelled enamelled
or other suitable reflectors b, the internal light or lights c, the perforated top d,
with vent e, the perforated plates f and k, the handle h and spindle i; and the
spring fastening clip or catch : - all combined, constructed and arranged
substantially as hereinbefore described and shewn.
