PROVISIONAL SPECIFICATION.
Improvements in Lights for Tram Cars and other Vehicles.
We, ALBERT EDWARD FLOOD, Gentleman, of 2, Beach Road, Sandymount,
County Dublin, and GEORGE JOSEPH SINCLAIR, Decorator, of 12, Westland Row,
Dublin, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in lights for tram cars and other vehicles
relates more especially to a means for enabling a passenger to distinguish the
tram cars having different destinations, at night when it is very difficult to read
the names on the side of the tram car. It has also for its object an improvement
in the light whereby the light rays are diffused more thoroughly and equally.
According to this invention, coloured glasses are placed immediately at the
back of the nulla-eyes nsed for tram-car lights. Behind the coloured glass
a piece of frosted or muffed glass is placed and this results in an equal and
thorough diffusion of the light rays. The coloured glasses are arranged to form
a distinguishing mark for each particular route by various combinations of
colours, and devices may be fitted so as to show at the light by which tram-cars
having the same coloured light may be distinguished.

COMPLETE SPECIFICATION.
Improvements in Lights for Tram Cars and other Vehicles.
We, ALBERT EDWARD FLOOD, Gentleman, of 2, Beach Road, Sandymount,
County Dublin, and GEORGE JOSEPH SINCLAIR, Decorator, of 12, Westland Row,
Dublin, 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 for improvements in lights for tram-cars and other vehicles
relates more especially to a means for enabling a passenger to distinguish the
tram-cars having different destinations, at night when it is very difficult to read
the names on the side of the tram-cur. It has also for its object an improvement
in the light whereby the light rays are diffused more thoroughly and equally.
According to this invention, coloured glasses are placed immediately at the
back of the bulls eyes used for tram-car lights. Behind the coloured glass
a piece of frosted or ground glass is placed and this results in an equal and
Din 17

page_text: thorough diffusion of the light rays. The coloured glasses are arranged to form
a distinguishing mark for each particular route by various combinations of
colours, and devices.
In order that this invention may be more clearly described reference is had
to the accompanying sheet of illustrative drawings on which
Fig. 1 is a section of a tram-car lamp constructed according to this invention.
Fig. 2 is a front elevation of the same and
Fig. 3 is a front elevation of a lamp fitted with a special distinguishing
design.
This lamp is provided with a bulls eye A in the ordinary manner and behind
this there is a sheet of coloured glass or glasses B the colour or colours of which
serves to denote the route on which the particular tram-car works. Behind this
sheet of coloured glass B a sheet of frosted or ground glass C is placed. It
will therefore be seen that the light from the lanip D has to pass through this
glass and an equal and thorough diffusion of the light rays is obtained thus
facilitating greatly the identification of the tram-car.
In the case of tram-cars using white lights there is no necessity for the
coloured glass B and in other cases the surface of the coloured glass may be
frosted so that there is no necessity for a separate sheet of the frosted or ground
glass.
In order to further provide for distinguishing various tram-cars where a
considerable number of different routes are traversed and the same colour would
therefore be employed for more than one set of tram-cars the coloured glass
may be in two or more divisions as indicated in Fig. 3 so that one half is one
colour and the other half another. Or various designs may be used in combina-
tions or colours in various ways.
In addition to or instead of the use of coloured glass only, letters may be used
so as to show at the lamp to indicate the route, or on a larger scale the destination
names may be shown.
..
The invention may also be used for railway advertisements, shops or for like
purposes, using lettering or other devices, ornamental or otherwise both with
transparent glass but with an opaque or semi-opaque ground.
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:―
(1) In combination with lights for tram-cars and other vehicles whereby a
particular route traversed is indicated, a sheet of frosted or ground glass either
adjacent to the sheet of coloured glass or itself forming the sheet of coloured
glass whereby the light rays will be more equally and thoroughly diffused
substantially as described.
(2) In combination with lights for tram-cars and other vehicles whereby a
particular route traversed is indicated, a sheet of frosted or ground glass either
adjacent to the sheet of coloured glass or itself forming the sheet of coloured
glass whereby the light rays will be more equally and thoroughly diffused,
the coloured glass being arranged so that the combinations of colours are shown,
and letters, words, or devices showing at the lamp substantially as described.
