A Reading Lamp for Railway Carriages and other Purposes.
I GEORGE COWLEY BINGHAM of Holland Works, Alscot Road Bermondsey in the
County of Surrey, Engineer do hereby declare the nature of this invention to be as
follows:-
The lamp consists of a receptacle for a candle made preferably of a cylinder
gathered in at one end forming the top and closed at the other by a cap. The
candle being placed within this receptacle is pressed upwards by a coiled spring. Of
a reflector having points fixed to it by means of which the lamp is easily affixed to
carriage cushions or the like. These points are so constructed as to close within the
reflector when not in use, and the reflector is of such form as to fit the aforementioned
receptacle closely when the lamp is closed. To the reflector is joined a part of such
shape as to form a cover to the lamp when closed, and a means of joining the
reflector to the aforementioned receptacle in such manner that upon turning the
reflector down unto the receptacle the top of lamp becomes closed.

COMPLETE SPECIFICATION.
A Reading Lamp for Railway Carriages and other Purposes.
I, GEORGE COWLEY BINGHAM Engineer of Holland Works, Alscot Road Bermondsey,
in the county of Surrey, 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 an improved pocket candle lamp provided with spikes for
attaching it to railway carriage cushions and the like and made to fold up into a
compact form protecting the spikes and making it convenient to carry.
The lamp consists of three principal parts viz. :-
1st. The container for the candle.
2nd. A reflector, forming also a protection for the object to which the lamp is
attached and also to carry the spikes by which same is hooked to any object.
3rd. Of a cap or connecting link, by which the reflector is connected to the body
of lamp, such as to prevent greatly its being heated, and to cover partially or wholly
the top end of body of lamp when closed.
To fully explain the nature of my invention I give the accompanying drawings
Fig. 1 being front elevation Fig. 2 side elevation Fig. 3 plan with reflector in section
Fig. 4 side elevation when closed.
At
In the drawings Fig. 1 to 4 inclusive (a & b) constitute the body or container of
lamp having its top end constructed such as to form a shoulder against which the
candle is pressed by a spring contained in the body of lamp in the ordinary way.
the bottom end (a) is a small raised part provided to prevent the falling off of the
cap (6) which is made to slide into a groove (¹) cut in the cap (b).
The part () is a cap to cover the end (a) of lamp when closed and a link to
connect the reflector (d) to the body (a) of the lamp, in such a manner as to greatly
prevent the heating of the reflector (d), when in use.
This cap (c) is made so that it will move freely about the axis of its connecting
point (c) to the body (a) of the lamp, and in such a manner that it will clear the top
end (a) of the body (a) of lamp.
Upon the projecting pieces or wings (c³) of the cap (c) is connected the reflector (d)
free also to move about the axis of its connection (d¹) to an extent limited by

page_text: shoulders upon the wings (c³) of cap (c) and the form of the wings (d²) upon the
reflector (d), thus causing the parts upon opening the lamp to assume their proper
positions.
To the top of the reflector (d) are attached the spikes (e) so shaped as to be, when
not in use, folded in a recess of the reflector (d) and when open to assume a stiff
position by means of a short projecting piece (e¹) coming in contact with the edge of
the reflector (d) in order that they can be the more readily inserted in a cushion or
the like.
There are various modifications admissablo in the lamp as described & illustrated.
1st. The body of lamp may be of prismatic shape instead of cylindrical. The wings
of the cap which covers the top may have instead of shoulders as described slight
projections against which the reflector catches or any similar arrangement by which
the parts are caused to assume their proper position upon opening the lamp.
The cap could be also modified in shape to cover more or less of the top of lamp.
In the reflector the spikes could be disposed of entirely or could be made to fold in
different manners upon the reflector.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1st. The combination and arrangement of parts in lamps substantially as described
and illustrated & their modifications.
2nd. In lamps connecting the reflector to the body or container by a link or links
substantially as described & illustrated.
3rd. In lamps connecting a spike or spikes to the reflector in the manner & for
the purpose substantially as described & illustrated.
