page_text: We, ALFRED ERNEST PURROTT and EDWARD WILLIAM WILLARD, both of
285, Broad Street, in the City of Birmingham, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention consists of improvements relating to carriage and like lamps, our
object being to construct the body of such lamps more expeditiously and in such
a manner as to give greater strength and neatness of appearance, than is obtained
by the ordinary method of construction.
-
In the construction of a lamp body in accordance with our invention we form
upon the edges of the back and the top and bottom plates, at the door side, a tube
or socket for the reception of a jointing wire or wires or the like. Such jointing
wires are preferably three in number, and one end of two of the wires being bent.
or formed at right angles, whilst both ends of the third wire are similarly bent or
formed at right angles. The ends of the wires having but one end bent or
formed at right angles are inserted within the tubes or sockets of the back and the
top and bottom plates respectively, whilst the wire having both ends bent or formed
at right angles has such ends inserted within the tubes or sockets of the top and
bottom plates and in the case of the end entering the bottom plate socket sufficient
length is provided to enable the wire to enter a socket or tube formed at the central
part of the lower edge of the plate forming the lamp door. Thus the wire in this
case forms a means of jointing or connecting the plates, and also serves as a pivot
or hinge pin for the door. We sometimes employ one wire of suitable length
and bent or formed to the required shape, instead of three wires as hereinbefore
described.
The other meeting edges of the plates forming the lamp body are flanged and
soldered or otherwise secured together.
By the employment of wires in conjunction with tubes or sockets formed upon
the edges of the plates as herein before described, we are enabled to build up the
lamp body in a true or square form with great expedition, and we are also enabled
to ensure that the bodies shall be finished to a uniform size, enabling the linings
or reflectors to be cut and finished to the exact dimensions required without the
necessity of fitting them in each lamp as in the ordinary manner. The glass fronts
or panes can be fitted independently of the lamp body.
We do not limit the application of our invention to carriage or similar lamps
of any one shape or configuration, but adapt it with such modifications as may be
necessary to suit particular services or requirements.

page_text: Improvements relating to Carriage and like Lamps.
We, ALFRED ERNEST PURROTT and EDWARD WILLIAM WILLARD, both of
Reliance Works, Alcester Street, (formerly of 285, Broad Street), in the City of
Birmingham, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists of improvements relating to carriage and like lamps, our
object being to construct. the body of such lamps more expeditiously and in such
a manner as to give greater strength and neatness of appearance, than is obtained
by the ordinary method of construction.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to.-
Figure 1 is a side elevation and Figure 2 a front elevation of a lamp body in
course of construction in accordance with our invention, the door being shown
partially open and the top and bottom plates detached.
Figure 3 is a front elevation of the lamp body showing the parts in position.
The same reference letters in the different views indicate the same parts.
In the construction of a lamp body in accordance with our invention we form
upon the edges of the back or inner plate A and the top and bottom plates B and C,
at the door side, a tube or socket as ab and c respectively for the reception of a
jointing wire or wires or the like. Such jointing wires are preferably three in
number as D, E, and F; one end of the wires E and F being bent or formed at
right angles, whilst both ends of the wire 1) are similarly bent or formed at right
angles. The ends of the wires E and F having but one end bent or formed at right
angles are inserted within the tubes or sockets a, b, and c, of the back plate A and
the top and bottom plates B and C respectively, whilst the wire D having both ends
bent or formed at right angles has such ends inserted within the tubes or sockets
of the top and bottom plates B and C. The end or arm of the wire F entering
the bottom plate socket is made of sufficient length to enable the wire to enter a
socket or tube formed at the central part of the lower edge of the plate forming the
lamp door; thus the wire in this case forms a means of jointing or connecting the
plates, and also serves as a pivot or hinged pin for the door. We sometimes employ
one wire of suitable length and bent or formed to the required shape, instead of
three wires as hereinbefore described.
The other meeting edges of the plates forming the lamp body are flanged and
soldered or otherwise secured together.
Instead of making one end or arm of one of the jointing wires of sufficient length
to form a hinge or pivot pin for the lamp door as herein before described, we some-
times employ a straight length of tube to pass through the central socket of the
door and also the sockets on the bottom plate; with such an intermediate tube no
long arm or end is required on one of the jointing wires.
By the employment of wires in conjunction with tubes, grooves, or sockets, formed
from the edges of the plates as herein before described, or attached to such edges,
we are enabled to build up the lamp body in a true or square form with great
expedition, and we are also enabled to ensure that the bodies shall be finished to a
uniform size, permitting the linings or reflectors to be cut and finished to the exact
dimensions required without the necessity of fitting them in each lamp as in the
ordinary manner. The glass fronts or panes can be fitted independently of the
lamp body.
We do not limit the application of our invention to carriage or similar lamps
of any one shape or configuration but adapt it with such modifications as may be
necessary to suit particular services or requirements.

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:
1. In the construction of carriage and like lamp bodies, the use of jointing or
connecting wires in combination with tubes, grooves, or sockets, formed from or
attached to the edges of the plates, substantially as described.
2. In carriage and like lamp bodies the combination comprising the jointing
and hinging sockets formed from one edge of the door and from the plate to which
such door is hinged, and the internal wires with an intermediate tube, substantially
as described.
3. A carriage or like lamp having its body built up substantially in the manner
and for the purposes described.
