Improvements in Cycle Lamps.
We, JOHN PARKER and THOMAS SANDERS, trading as Parker and Sanders, of
Aston Brook Street, in the City of Birmingham, Manufacturers, and JOSEPH
BENJAMIN WORTON, of Tillingham Street, Sparkbrook, Birmingham aforesaid,
Manager of Works, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to Improvements in Cycle Lamps, and has for its objects,
first, increasing the illuminosity of the light of the lamp; secondly, accessibility to
the interior of the lamp, and thirdly, simplicity of the construction and arrangement
of the parts.
The body of the lamp is made of the general figure of a drum, with an open upper
part or section top, hinged to one side of the said body part, and carrying at its
crown a chimney or products of combustion outlet, fitted with an interiorly arranged
wind guard for intercepting wind currents.
Thus, the general figure of the body of the lamp is that of a drum, with the
opposite flat ends forming the back and front to the said body part, which is
sectional in construction, and of which one part forms a hinged closure, which may
comprehend an upper part of the drum, or it may comprehend one half or more of
it, and which said part is hinged, and forms as it were a top door which carries the
chimney, which is preferably closed at top and pierced on its sides, and having up
the interior middle of it, a wind guard, open at top only to the piercings of the
chimney proper.
The said removable and hinged top may be made if necessary to comprehend one
of the sides, and may be fitted or not with a side-light, whilst the fixed side may
carry a side light.
The supporting arms are connected to the back of the lamp as usual, whilst the
front of the lamp is fitted with an ordinary bell, coned or hopper shaped outwardly
and with the same fitted with two double-convexed lenses, one fitted or disposed at the
inner part of the said bell, and the other at the outer part, and by means of which,
increased illuminating power is acquired.
Thus, by employing two double-convex lenses with one bell, the pencil of rays of
light is multiplied, and the luminous field greatly increased in intensity.
Thus I fit within the narrow end of the bell which projects into the interior of
the body of the lamp through the front, a small double-convex lens, and at the
enlarged and outer end of the bell, I fit a large double-convex lens, and which lenses
are separated from each other by a considerable intervening space, and the same
may be mounted within bezels, hinged to or removable from the said bell.
The base of the lamp constitutes the oil-tank, and may be tapered outwardly
towards the base, and with the said taper disposed in the direction of the sides of
the drum body part.
Fitted within the interior of the base and oil tank comes the burner, with the
winder stem passing through a slot in one of the side walls.
The burner part, with wick casing, is removable, whilst the back of the lamp is
fitted with a fixed or removable reflector, and the bottom of the body of the lamp
is pierced with air-holes covered by inside disposed wind-guards to prevent the
incoming currents from impinging upon the flame.
Catches are arranged to hold the sectional parts in their assigned position.
By the employment of two lenses, the primary one cannot become smoked or

page_text: sweated as all connection with the interior of the lamp is cut off by the secondary
aud inner lens.

improvements in Сусте Lamps.
We, JOHN PARKER and THOMAS SANDERS, trading as Parker and Sanders,
of Aston Brook Street, in the City of Birmingham, Manufacturers, and JOSEPH
BENJAMIN WORTON, of Tillingham Street, Sparkbrook, Birmingham aforesaid,
Manager of Works, 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 Cycle Lamps, and has for its objects,
first, increasing the illuminosity of the light of the lanp, and secondly, accessibility
to the interior of the lamp.
Thus in carrying out one part of our invention, the front of the lamp is provided
with an ordinary conoidal bell, fitted with two lenses or two double-convexed lenses
one disposed at the inner part of the said bell, and the other at the outer part, and
by means of which, increased illuminating power is acquired.
By employing two lenses within one bell, the pencil of rays of light is multiplied,
and the luminous field is greatly increased and the light intensified.
Thus I fit within the narrow end of the bell, which projects into the interior of
the body of the lamp through the front, a small double-convex lens, and at the
enlarged and outer end of the bell, I fit a large double-convex lens, and which lenses
are separated from each other by a considerable intervening space, and the same
may be mounted within bezels, hinged to or removable from the said bell.
The top part of the lamp is removable, so as to make the interior of the lamp
accessible for the purpose of cleaning the said interior and the inside face of the
inner lens, and if necessary, for lighting the wick.
Figure 1 of the accompanying drawing represents in vertical section, a lamp
provided with improvements in accordance with our invention.
Figure 2 represents a vertical section of the same, taken at right angles to the
section Figure 1.
a is the body of the lamp, having an open top a², and fitted with other accessories
common to ordinary lamps, and with the said open top fitted with a removable cowl
or chimney a³, which may be hinged to the body at a', and carry a reflector aº,
which turns outwardly with the said top when the lamp is required to be opened.
The body part, may, if necessary, be of a drum or other shape, and the reflector a',
may be affixed to the inside back of the lamp instead of being carried by the
removable top a³.
bis conoidal shaped bell, fitted to the front of the lamp, and provided with two
double-convex lenses c, d, separated from each other by an intervening space e.
By employing magnifying lenses in duplicate, the primary and outer one d, cannot
become smoked or sweated, as its connection with the interior of the lens is cut off*
by the secondary and inner lens c.
Instead of employing two lenses within the interior of the bell, we may fit the
same with three or more double-convex lenses.
Figure 3 represents a side elevation of the detachable cowl, chimney or head.

page_text: Figure 4 represents a front elevation of the same.
In this head, the same is made to slide into position, instead of turning upon a
joint, and the webbed or flanged edges may slide in grooves or guides on the inside.
back of the body of the lamp.
a³ is a detachable cowl or top, with a leading flange a, and a reflector a³, and a²
are flanged edges.
Instead of the inner lens being carried by the walls of the bell it may be carried.
by the walls or shell of the lamp, adjacent to the entrance to the bell.
Figure 5 represents a still further form of our invention.
In this arrangement, the entrance to the bell, or the lamp shell adjacent to the
bell is glazed, so as to protect the lenses of the bell from being smoked.
a is the body of the lamp, b the bell, c, d are the lenses, separated by a space e,.
and is the plain glazing situated at the entrance to the said bell.
Figure 6 shows a further modification of our invention, in which plano-convexed
lenses are employed instead of double convexed ones.
a is the body part of the lamp, b is the bell, c, d are plano-convexed lenses,.
having their concaved sides c, d presented outwards, and their flat surfaces c², d²,.
presented to each other, and with an intervening space e, coming between them.
Having now particularly described and ascertained the nature of our said inven
tion, and in what manner the same is to be performed, we declare that what we.
claim is :-
First. In cycle lamps, fitting or providing the lamp, or the bell of the lamp, with
two or more double-couvexed lenses, separated from each other by an intervening
space or spaces, substantially as described and set forth.
Secondly. Fitting or providing the lamp, or the bell of the lamp, with lenses, or
lenses and glazings, substantially as described and set forth in Figures 5 and 6.
