PROVISIONAL SPECIFICATION.
Improvements in Lamps for Streets or the like.
I, THOMAS HUDDERS, of Dale Street Tin Works, Shaw, in the County of
Lancaster, Tinplate Worker, do hereby declare the nature of this invention to be
as follows:-
The invention relates to the application of down wires or similar contrivances
such as described in my Specification No. 4508 dated March 13, 1891, to lamps for
lighting streets or such like places or open areas.
In carrying out my invention as applied to a street lamp for instance I dispense
with the usual down bars forming the division or junction between the panes of
glass, and fix in their places what I term down wires. These wires, or it may be
very small tubes or even thin narrow sheets of tin plate or the like, are secured to
the base and top of the frame composing the lamp in any suitable manner such as
by attaching to lugs or projections cast to or affixed to the top and bottom frame.
These lugs may be drilled and tapped if desired or simply drilled and the wires
screwed to correspond and passed through them, each being secured by a nut or
nuts or collar and nut. It will be obvious that although I have described the wires
as being screwed and secured by nuts or such like contrivance, they may be con-
nected to the top and bottom frame in any desired manner without departing from
the nature of my invention.
The panes of glass are placed in the interior or behind the wires making each a
joint with the other or in some cases the panes may be placed at the exterior of
the wires. To keep the panes of glass in place, lugs, pegs or such like projections
or a light ring of metal may be attached to the bottom and top frames.
In other respects the frame of the lamp, that is to say, the top and bottom or in
some cases the back of the lamp may be constructed in any desired or usual manner.
Further, the lamps may be made in any shape, the essential feature of my inven-
tion consisting in the application of the down wires. in place of the present
division bars.
The advantages obtained by the use of the down wires such as described are
that the lamp will give a clearer and a better light and at the same time dispense
with the casting of shadows such as is done by the lamps at present in use.
Dated this 26th day of February 1892.

COMPLETE SPECIFICATION.
Improvements in Lamps for Streets or the like.
"I, THOMAS HUDDERS, of Dale Street Tin Works, Shaw in the County of
Lancaster, Tinplate Worker, 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 :-
The invention relates to the application of down wires or similar. contrivances
such for instance as are described in the Specification accompanying my application
for Letters Patent No. 4508 dated March 13th 1891 to lamps for lighting streets
or such like places or open areas and whereby the shadows usually cast from
or by such lamps may either be entirely eliminated or at any rate considerably
lessened.

page_text: In order that the invention may be fully understood I will proceed to explain
the same by reference to the accompanying drawings in which
Fig. 1 is an elevation of a street lamp constructed in accordance with my
invention.
Fig. 2 section of a modified form.
Fig. 3 plan of same and Fig. 34 an enlarged view of the top C and
Figs. 4 and 5 are sectional elevations of other modified forms.
In carrying out my invention and referring more particularly to Fig. 1 I dispense
with the usual down bars forming the division or junction between the panes of
glass and fix in their stead what I term down wires. These wires A-or it may be
very small tubes or even thin narrow sheets of tin plate or the like-are secured to
the base B and top C of the frame composing the lamp in any suitable manner
such as by soldering as at b and c. It will thus be seen that these wires form a
medium for supporting the top of the lamp from the base or vice versa.
The panes of glass are cut to the required shape and are placed in the interior
of the lamp frame or behind the wires making each a joint with the other or in
some cases I may place the panes at the exterior of the wires. To keep or retain
the panes in position lugs pegs or such like projections may be attached to the
base B and top C, these being bent over against the glass.
I may here remark that suitable provision may be made in the shape of a door
at the side of the lamp for access to the interior thereof for cleaning and like
purposes and also that the base B and top C of the lamp may be constructed
in any desired manner so far as the ventilating and reflecting arrangements are
concerned.
Referring now to Fig. 4 it will be seen that the wires A are attached to the.
base B and top C by means of lugs 6¹ and c¹ which latter are formed integral with
the top and base respectively. These lugs may be drilled and tapped, or drilled
only, and the wires screwed to correspond and passed through them, each end of
the wires being secured by a nut or nuts or collar and nut. I would have it under-
stood, however, that although I have described the wires as being screwed and
secured by nuts or such like contrivances they may be connected to the top and
bottom frame of the lamp in any desired manner without departing from the nature
of my invention. It will be seen that in this case the base B and top C are simply
channelled at 6" and c" for the reception of the ends of the glass. Tops and bases
of this class may be made of cast metal if desired.
Referring to Figs. 2, 3 and 34 it will be seen that the down wires are connected
to the base B and top C as before but the panes of glass are kept in place by metal
rings D loose or capable of being withdrawn when required. These metal rings
may simply be plain in cross section and screws passed through to make them rigid
with the base and top of the lamp respectively. I, however, prefer to make them
with a small flange & and when this method is used I flange the panes of glass at
each end or form one or more lugs upon each of them, these lugs or flanges resting
upon the flange d of the top ring D whilst the bottom lugs or flanges serve to
hold in conjunction with the down wires-the base B of the lamp in position.
With this construction it is possible to entirely dispense with the down wires as
the flanges on the glass and metal rings serve to keep the whole of the parts
together as shown in Fig. 5. Each of the metal rings D may be secured or drawn
tightly against the base B and top C respectively by screws E or the like as shown
in Figs. 2, 3, 3* and Fig. 5.
Lamps constructed in acordance with my invention do not cast any shadow, the
down wires practically presenting no obstruction to the light whilst they are much
more easy to repair than lamps at present in use.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The application to lamps for streets or such like places or open areas of down

page_text: wires or similar contrivances such as described in my Patent No. 4908 dated
March 13th 1891.
2. Lamps for streets or such like places constructed and arranged substantially
as hereinbefore described.
3. Lamps for streets or such like places constructed and arranged substantially
as hereinbefore described with reference either to Fig. 1, to Figs. 2 and 3; to
Fig. 4 or to Fig. 5.
