Improvements in Lamps for Bicycles and other Vehicles and
Carriages.
We RICHARD WHITEHOUSE of No. 16 Cooksey Avenue, Small Heath, near
Birmingham in the County of Warwick, Glass Cutter, and DANIEL HEMMING
GILL of No. 8, Henshaw Road, also of Small Heath Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to new or improved methods of construction and arrange-
ment of the lenses of lamps for bicycles and other vehicles and carriages.
In our invention as applied to bicycle or other lamps we use, instead of the
ordinary circular convex lense, a series of two, three, or more rectangular lenses,
made and mounted as follows.
The lenses we use are preferably of the plano-convex type, the back being flat
and the front forming a cylindrical segment, the axis being parallel with the
back of the lense and at right angles or nearly so, to the horizontal axis of the
lamp.
These lenses when say three are used, are mounted, one straight in front, and the
other two contiguous, one on each side, the latter set back at an angle, so that
in a horizontal section of the front of the lamp the lenses would shew as the three
sides of a half hexagonal figure.
The lenses are mounted in metallic frames adaptable to any angle with each
other horizontally at which they may be set, and the lense holder or funnel is so
shaned as to match the position of the lenses.
The top and bottom of the convex face of each lense is bevelled so as to form an
edge of uniform thickness for fixing. The inside of the funnel may be polished,
and additional reflecting surfaces may be arranged at the back of the lamp.
Instead of three such lenses we may use four, five, or more, in this case the
lenses are made narrower in proportion to their height. Also instead of being
absolutely rectangular the lenses may have their corners slightly rounded or
chamfered.
The horizontal section of the lenses may be varied as by double convex or
concavo convex sections without departing from the nature of this invention.
Dated this 13th day of June 1896,

WHITEHOUSE.

Improvements in Lamps for Bicycles and other Vehicles and
Carriages.
We, RICHARD WHITEHOUSE, of Cooksey Road Small Heath Birmingham in
the County of Warwick Glass Cutter and DANIEL HEMMING GILL of Henshaw
Road Small Heath Birmingham aforesaid 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 new or improved methods of constructing and
arranging the lenses of lamps for bicycles and other vehicles and carriages.
In our invention as applied to bicycle or other lamps we use, instead of the
ordinary circular convex lense, a series of two three or more rectangular lenses
made and mounted as follows:-
The lenses we use are preferably of the plano-convex type the back being flat
and the front forming a cylindrical segment the axis being parallel with the
back of the lense and at right angles or nearly so to the horizontal axis of the
lamp.
These lenses when say three are used are mounted one straight in the front and
the other two contiguous one on each side, the latter lying back at an angle so that
in a horizontal section of the front of the lamp the lenses would shew as the three
sides of a half hexagonal figure. The lenses are mounted in metallic frames
adaptable to any angle horizontally at which they may be set and the lense holder
or funnel is so shaped to match the position of the lenses.
The top and bottom of the convex face of each lense is bevelled so as to form
an edge of uniform thickness for fixing.
The inside of the funnel may be polished and additional reflecting surfaces
may be arranged at the back of the lamp to correspond with the angles of the
lenses.
Instead of three such lenses we may use four, five, or more, in this case the
lenses are made narrower in proportion to their height, also instead of being
absolutely rectangular, the lenses may have their corners slightly rounded or
chamfered. The horizontal section of the lenses may be varied as by double
convex or concavo-convex sections without departing from the nature of this
invention.
In the accompanying drawings
Figures 1 and 2 are front and side elevations respectively of a cycle lamp made
in accordance with our invention.
Figure 3 is a horizontal section through the lenses or glazed portion of the
lamp. Figures 4 and 5 are similar sections shewing modifications in the number
and arrangement of the lenses.
Figures 6 and 8 shew elevation and horizontal section of the primary form of
plano-convex lense used in this invention. Figures 7. and 9 represent a modified
form of same.
Figures 10 and 11 shew a lense with rounded corners and vertical section of
same.
In the lamp shewn in Figures 1, 2 and 3 A is the oil tank or base B is the body
case or funnel of the lamp and C. the cowl at top. In these figures the lamp is
shewn as fitted with three of the new or improved lenses marked a a and mounted
in the frames b b. The bevellings of the ends of the lenses are shewn at c c. The
lamp may be made as usual to open at the back or side or the lense frames may be
hinged and fitted so that they may be opened for cleaning. The reflector is shewn

page_text: at d d as common to the set of lenses or separate reflectors may be used opposite
each lense as shewn at da d³.
In Figure 4 is shewn a modified arrangement of the glazed front of the lamp
for four lenses as a being the front lenses and a3 a³ the side lenses. The latter
may be made of narrower section than the front lenses as shewn if preferred.
Figure 5 is another modification shewing a glazed front with five lenses
marked a a¹.
The lenses are either cut from flat pieces of glass or may be cast to shape in
moulds and afterwards ground and polished.
In Figures 6 and 8 we shew the simplified form in which we make our lenses of
the plano-convex type. In Figures 7 and 9 we shew another form we use with a
bevelled edge e e all round. We further also use similar lenses with rounded
corners as shewn at f f in Figures 10 and 11.
For other vehicles and carriages we construct lamps in essentially the same
manner as above described the size of the lenses and the construction of the body
of the lamp and the mode of attachment being readily varied to suit any class of
lamp to which our invention may be adapted.
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:
1. The construction of lenses for bicycle and other vehicle lamps of a rectangular
shape and plano-convex in horizontal section and the sides parallel vertically,
substantially as and for the purposes hereinbefore described and set forth.
2. The combination of three or more such lenses in the glazed front of bicycle
and other vehicle lamps in the manner and substantially as and for the purposes
herein before described and set forth.
