PROVISIONAL SPECIFICATION:
Improvements in Cycle. and: Road-vehicle Lamps.
We, JOHN PARKER and CHARLES HUDSON, trading as, S. Parker.. Hudson and.
Company, of. Midland Works, King's Norton, near the, City, of Birmingham,
Manufacturers, and JOHN HENRY, SMITH, of, 94: Cooksey Road, Small Heath near
Birmingham aforesaid, Foreman of. Works, do hereby declare the nature of this
invention to be as follows:
This invention relates to cycle and carriage lamps, and has for its object, the
increasing of the illuminating power of such lamps and the making of the
interiors of the same fully accessible for cleansing, lighting and other purposes.
A lamp constructed according to our improvements consists of an oblique-sided
frame with a closed back, which constitutes the door, and a breaker and crown
surmounting the frame, which is glazed with outside-convexed and inside-plain
lenses. The back carries the usual compensating arms and socket, and is provided
on one side with a stalk or pivot which works in. a sleeve carried by the lamp
body and forms a joint upon which the said body swings.
Thus, the body of the lamp consists of a three-sided frame, open at back and
having a crown and breaker at top and an oil tank or oil tank receptacle at the
base and with air piercings formed through the said body at the junction of
the frame with the base and having an inside breaker partially surrounding the
burner and adapted to baffle direct currents of air passing into the interior of
the lamp. The front opening of the frame, is enclosed or glazed by a plano-convex
lens, with the straight face presented inwards, whilst the outside convex face has
bevelled boundary edges, and the sides of the frame are inclined from front to
back at an angle of: about 25 degrees and are glazed with like plano-convex lenses
as the front.
A reflector is placed at the middle of the, inside of the back facing the front
glazing but acting in common for both front and side lights, so that the rays of
light falling upon the reflector are dispersed through both side lights and front
lights.
When the lamp is in use, it has the appearance of an unbroken ball of light.

We, JOHN PARKER and CHARLES HUDSON trading as S. Parker, Hudson and
Company, of Midland Works, King's Norton, near the City of Birmingham,
Manufacturers, and JOHN HENRY SMITH, of 94 Cooksey Road, Small Heath, near
Birmingham aforesaid, Foreman of Works, do hereby declare the nature of this

page_text: 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 cycle and carriage lamps, and has for its objects, the
increasing of the illuminating power of such lamps and the making of the interior
of the same fully accessible for cleansing, lighting and other purposes.
A lamp constructed according to our improvements consists of an oblique-sided
frame with a closed back, which constitutes the door, and a breaker and crown
surmounting the frame, which is glazed with outside-convexed and inside-plain
lenses. The back carries the usual compensating arms and socket, is provided on
one side with a stalk or pivot which works in a sleeve carried by the lamp body
and forms a joint upon which the said body swings.
Thus, the body of the lamp consists of a three-sided frame, open at back and having
a crown and breaker at top and an oil tank or oil tank receptacle at the base and with
air piercings formed through the said body at the junction of the frame with the base
and having an inside breaker partially surrounding the burner and adapted to baffle
direct currents of air passing into the interior of the lamp. The front opening of the
frame is enclosed or glazed by a plano-convex lens, with the straight face presented
inwards, whilst the outside convex face has bevelled boundary edges, whilst the
sides of the frame, which are inclined from front to back at an angle of about
25 degrees, are glazed with like plano-convex lenses as the front.
Thus each of the said lenses, which may have right angled, inclined or circular
boundary edges, has its outer face convexed relative to its inner face in one direction
and parallel thereto in the right angled direction, alike unto a segment cut off
the face of a solid cylinder in its longer direction, or in the direction of its
axis.
A reflector is placed at the middle of the inside of the back facing the front glazing,
but acting in common for both front and side lights, so that the rays of light falling
upon the reflector are dispersed through both side lights and front lights.
When the lamp is in use, it has the appearance of an unbroken ball of light..
Figure 1 of the accompanying drawings represents a side elevation of a cycle
lamp made and provided with glazings according to our improvements.
Figure 2 is a side elevation of the same.
Figure 3 is a transverse section upon the dotted line x Figure 1.
cross
Figure 4 represents a front elevation of one of the glazings; Figure 5 is a
section thereof on the dotted line x', Figure 4 and Figure 6 a vertical section on the
dotted line .².
Figures 7, 8, 9 and 10 represent front elevations, cross sections on ³ and vertical
sections on a, of other forms of glazings.
In Figures 1 to 6, a is the base or oil tank, b the body part and c the hood or
crown. d are the glazings carried in frames d², 3, with the side frames d², being
inclined at an angle to the front frame d³, and with a reflector de, located at the back
of the lamp in front of the said glazings and serving in common for them all. Each
of the glazings has a plain or straight surface at back d¹, and its outer face d³, is
convexed in one direction, ciz., crosswise, and is parallel to the inner face in the other
direction.
The lenses may have chamferings or bevellings de, d', at their opposite sides and
ends.
Figures 7 to 10 are marked with the same letters of reference as Figures 1 to 6.
Figure 11 represents an elevation of a modified form of lamp, and Figure 12 is
a cross section of the same upon the dotted line a, Figure 11.
d, d³ are the side and front glazings of the same character as those described
and fitted within frames e, one of which may be hinged to act as a door, whilst
coming opposite the said glazings are three reflectors f,fif, situated at the back of the
lamp.
The application of our invention to carriage lamps differs in no essentia! respect
from its application to cycle lamps as herein described.
"

page_text: 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. In the lenses or glazings of cycle and carriage lamps, making the same.
of a plano-convex cross section in one direction and with the inuer and outer faces
parallel in the other direction, substantially as described and set forth.
Secondly. The improved construction of cycle and carriage lamps, consisting of a
body or frame, fitted with glazings or lenses of the type referred to in the preceding
claim and with the side glazings directed at an angle with respect to the front
glazings, substantially as described and set forth.
Thirdly. In cycle and carriage lamps, the combination with a triple glazed frame,.
of three reflectors arranged immediately opposite the said glazings, substantially as.
described and set forth in Figures 11 and 12.
