Improvements in Glazings or Lenses for Cycle and Carriage Lamps.
We, JOHN PARKER, Director of the Parker Lamp Manufacturing Company
Limited, of Leopold Street, in the City of Birmingham, and JOHN HENRY SMITH,
of No. 94, Cooksey Road, Small Heath, Birmingham aforesaid, Foreman of Works,
do hereby declare the nature of this invention to be as follows:-
This invention has relation first to the glasses, glazings or lenses of cycle and
carriage lamps and secondly to securing such glazings in position.
The first part of our invention has for its object, to combine two, three or more
lenses in one integral glazing, without the employment of intervening connecting
bars or framings, so that two, three or more lights or lens are integrally formed
and mounted in a single boundary frame.
Thus in ordinary lamps having double or triple lenses each glazing is mounted
or carried in a separate metal frame, hence the light of the lamps is obstructed by
the intervening bars which form the divisions between the lenses or glasses.
In carrying out one form of our invention, we take an ordinary lamp body or
bell, and fit within the open front end of the same, a triple-light glazing, of which
the middle light may be of that type wherein the middle of the front of the same is
parallel to the back in a vertical direction and of a plano-convex figure in horizon-
tal section, whilst the top and bottom ends of the concaved front are bevelled. The
opposite side glazings which are connected to the middle or front light by thin
glass webs, are inclined backwards at an obtuse angle, with respect to the said front
light, which side lights may be either of the plano-convex or bulls eye type, and
are preferably of a D figure in their outline shape, with their straight edges coming
adjacent to the vertical sides of the middle light. Three lights are thus combined
in the one glazing.
This compound lens or glazing is mounted in a frame, bezel or beading, forming
a part of, or hinged within the front opening of the lamp cone or body part.
By setting back the side portions of the compound glazing at an angle relative to
the front, we are enabled to dispense with the ordinary side lights, and the rays of
light directed from the lamp are dispersed or spread over a larger area.
We do not limit ourselves to the particular arrangement, number, outline shape
and sectional shape, of the combined lights, as two, three or other number of lights
of any section or shape may be arranged in a variety of ways without departing
from the nature of our invention, so long as the same are made or formed in one
integral piece, without the employment of any joining-up frames or connecting
pieces.
According to the second part of our invention, glazings of any special or ordinary
type may be secured in position by forming upon the edges of the mouth of the bell,
body or other glass seating, a continuous series of ears or cleats; which when turned
over or clinched upon the edges of the glazing, secure the same firmly in position.

We, JOHN PARKER, Director of the Parker Lamp Manufacturing Company
Limited, of Leopold Street, in the City of Birmingham, and JOHN HENRY SMITH,
of No. 94, Cooksey Road, Small Heath, Birmingham aforesaid, Foreman of Works,
dö 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 has relation to the glasses, glazings or lenses of cycle and carriage
lamps.
The said invention has for its object, to combine two, three or more lenses in
one integral glazing, without the employment of intervening metallic connecting
bars or framings, so that two, three or more lights or lens are integrally formed
and mounted in a single boundary frame.
In ordinary lamps having double or triple lenses, each glazing is mounted or
carried in a separate metal frame, hence the light of the lamps is obstructed by the
intervening bars forming the divisions between the lenses or glasses but according
to these improvements such framing bars are dispensed with, and the triple lens,
which is made in one solid piece, is secured in a bezel, mount or frame which comes
around the boundary of the same, so that the light of the lamp is not obstructed or
broken up by any opaque parts crossing or coming between the lens.
Figure 1 of the accompanying drawing represents a front elevation of a cycle
lamp, fitted with an integrally formed triple lens constructed according to our
invention.
Figure 2 is a front elevation of the said lens separately.
Figure 3 is a horizontal section of Figure 2 upon the dotted line a.
Figure 4 is a vertical section down the centre of the middle lens upon the dotted
line, Figure 2.
Figure 5 is a plan of the said lens and its mount, frame or bezel.
Figure 6 is an edge view of Figure 5.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
In carrying out the form of our invention represented in the said figures, we take
an ordinary cycle lamp body a, and fit within the opening or mouth at the front
end of the same, a frame or bezel b, wherein we mount a triple-light glazing, or
triple lens c, of which the middle lens or light c¹, may be of that type wherein the
middle of the front of the same is parallel to the back in a vertical direction (see
Figure 4) and of a plano-convex figure in horizontal section (see Figure 3) whilst
the top and bottom edges of the concaved front are bevelled as seen in Figures 2
and 4. The opposite side glazings, which are connected to the middle or front
light by thin glass webs 3, and are preferably inclined backwards at an obtuse
angle with respect to the said front light, may be either of the plano-convex or
bulls eye type, and are preferably of a D figure, in their outline shape (see
Figures 1 and 2) with their straight edges c, coming adjacent to the vertical
sides c, of the middle light. Three lights are thus combined in the one glazing..
The frame, bezel or beading b, wherein this compound lens or glazing is
mounted, forms a part of, or is hinged, within the front opening of the lamp cone
or body part, and may be provided with inwardly sloping flanged edges (such as
marked b¹, in Figures 5 and 6) for socketting or telescoping into the mouth of the
said body or cone.
I
. [
By setting back the side portions of the compound glazing at an angle relative to
the front, as described,' we are enabled to dispense with the ordinary side lights,

page_text: and the rays of light directed from the lamp are dispensed or spread over a large
area.
We do not limit ourselves to the particular arrangement, number, outline shape
and sectional shape, of the combined lights, as two, three or other number of lights
of any section or shape may be arranged in a variety of ways without departing
from the nature of our invention, so long as the same are made or formed in one
integral piece, without the employment of any joining-up frames or connecting
pieces.
Instead of making a compound lens from three integrally formed lights arranged
as described and illustrated, two lights only, set at an angle relative to one another
may be made in one integral piece of glass, or four or other number of lights may
be made in one piece of glass and arranged at suitable angles to comprehend the
desired figures.
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: A compound or multiple lens or glazing for cycle and carriage lamps,
comprising two or more lights integrally formed, whereby the employment of metal
connecting bars or frames is dispensed with.
Secondly: A triple or compound lens for cycle and carriage lamps, in which
the middle light is of a plano-convex in cross-section and parallel sided in vertical
section, whilst the side lights are of a plano-convex section in all directions and are
integrally united with the middle light, substantially as described and set forth.
