of Cambridge Street Works Birmingham in the County of Warwick Merchants
and Manufacturers do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HALL LAMPS AND OTHER LAMPS" to be as follows:-
My invention consists in the improvements hereinafter described in constructing
or building up and connecting together the metallic and glazed parts of hall lamps
and other lamps.
I make or build up the glazed part of the lamp of strips of by preference plate
glass and support the said strips of glass and bind and secure them together in the
following manner
In glazing the lamp body according to my Invention I bind a series of vertical
strips between a top and bottom metallic ring or frame the said rings or
frames being supported by and fixed upon the central gas tube of the lamp by
means of radial arms. The said metallic rings or frames have in their opposed
faces grooves or depressions for receiving the top and bottom edges of the glass
strips. After the top ring or frame has been depressed upon the top edges of the
glass strips supported on the bottom ring or frame the said top ring or frame is
fixed in its place by a screw connection on the central gas pipe so as to bind the
strips between the top and bottom rings or frames. The longitudinal edges of the
vertical strips of glass are not quite in contact so that currents of air may pass
between them into the body of the lamp for ventilating the lamp.
The glass strips may be arranged so as to form a lamp body either square or
rectangular in plan or of a polygonal or star liko figure in plan.
The strips of plate glass which I use may either be coloured or colourless or
painted and the edges of the said strips or panes may be bevilled.
Lamps constructed according to my invention are particularly applicable to the
lighting of halls and vestibules but are also applicable to the lighting of shops
rooms and buildings.

page_text: I CHARLES WALKER TORR of the firm of Robert Walter Winfield and Company
of Cambridge Street Works, Birmingham in the County of Warwick, Merchants
and Manufacturers do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN HALL LAMPS AND OTHER LAMPS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention consists of the improvements herein after described in constructing
or building up and connecting together the metallic and glazed parts of ball lamps
and other lamps.
I make or build up the glazed part of the lamp of strips of, by preference, plato
glass and support the said strips of glass and bind and secure them together in the
following manner.
In glazing the lamp body according to my invention I bind a series of vertical
strips between a top and bottom metallic ring or frame, the said rings or frames
being supported by and fixed upon the central gas tube of the lamp by means of
radial arms.
The said metallic rings or frames have in their opposed faces, grooves or
depressions for receiving the top and bottom edges of the glass strips. After the
top ring or frame has been depressed upon the top edges of the glass strips
supported on the bottom ring or frame the said top ring or frame is fixed in its
place by a screw connection on the central gas pipe so as to secure the strips
between the top and bottom rings or frames. The longitudinal edges of the vertical
strips of glass are not quito in contact so that currents of air may pass between
them into the body of the lamp for ventilating the lamp.
The glass strips may be arranged so as to form a lamp body either square or
rectangular in plan, or of a polygonal or star like figure in plan.
The strips of plate glass which I use may either be coloured or colourless or
painted and the edges of the said strips or panes may be bevilled.
Lamps constructed according to my invention are particularly applicable to the
lighting of halls and vestibules but are also applicable to the lighting of shops
roons and buildings.
Figure 1 of the accompanying Drawings represents in side elevation a hall lamp
constructed according to my invention; Figure 2 represents in side elevation, drawn
to a larger scale, the top and bottom metallic rings or frames and the vertical
glass strips between them; Figure 3 represents a plan of the inner face of either
the bottom or top metallic ring or frame of the lamp, drawn to the same scale ns
Figure 2, and Figure 4 represents in section, drawn to a larger scale, the screw
connection for securing the glass strips between the two rings or frames and for
attaching the body of the lamp to the upper part of the gas pipe.
The same letters of reference indicate the same parts in Figures 1, 2, 3 and 4.
a is the top metallic ring or frame and b is the bottom metallic ring or frame
between which rings a and b the series of vertical strips of glass c, preferably

page_text: bevilled on their edges is supported and secured together. The opposed faces of the
rings or frames a, b are formed with seats pockets or grooves d, d for receiving the
top and bottom edges of the glass strips c. The shape of the seats, pockets or
grooves d d is seen in Figure 3. The seats pockets or grooves d are shaped and
arranged on the rings a, b according to the figure in plan of the lamp body to bo
formed. In the drawing a lamp body having a polygonal or star like figure in
plan is represented. The several seats, pockets or grooves d are separated a short
distance apart (see Figure 3) so that the longitudinal edges of the strips of glass
are not quite in contact; currents of air are thereby permitted to pass between the
glass strips into the body of the lamp for ventilating the lamp. The bottom ring
or frame b is carried by the radial arms e, e screwed or otherwise connected to
the bottom of the central gas pipe f immediately above the gas tap g.
The top ting a is connected to the tubular sleeve h by the radial arms i and the
said sleeve is connected to the screwed upper part of the gas pipe f carrying the
bottom ring b in the manner which will be understood by reference to the enlarged
sectional view Figure 4. The upper part of the gas pipe fis screwed at f* and on
the screwed part f' a regulating stop nut k is screwed the said screw nut k
supporting the bottom of the tubular sleeve h carrying the top ring or frame a.
The tubular sleeve h is fixed in its place on the screwed part f2 of the gas pipe f, f*
and the said gas pipe f, f'at the same time screwed to the upper screwed gas
pipe by means of the screw nut l.
In building up the glazed body of the lamp and connecting the parts together
I proceed as follows:-
The lower ends of the glass strips c are first arranged in the seats, pockets or
grooves d in the bottom ring or frame b fixed to the gas pipe f. The tubular
sleeve h carrying the top ring a is next placed on the screwed end of the gas
pipe and supported on the screw nut k which has been properly adjusted on the
said screwed end f. The top ring a is thereby depressed upon the top edges of the
glass strips c, c, the seats pockets or grooves d on the under face of the said top
ring a taking upon the said top edges of the glass strips.
The glass strips c c are thereby secured between the top and bottom rings or
frames a, b. The top ring a is next fixed in its place by screwing home the scrow
nut upon the end of the screwed part f' of the gas pipe and the upper part ƒ³ of
the gas pipe is screwed into the nut as seen in Figure 4.
The body of the lamp made mainly of a top and bottom ring and vertical glass
strips is in this way built up and the parts connected together.
Figure 5 represents in side elevation a hall lamp or other like lamp constructed
according to my invention; Figure 6 represents a plan of innerside of the top ring
of the body and Figure 7 a plan of inner side of the bottom ring of the body.
In this arrangement the strips of glass, preferably of opal glass, are inclined
instead of vertical and are of a tapering figure the diameter of the top ring a being
considerably less than that of the bottom ring b, the seats, pockets or grooves din
the opposed faces of the said top and bottom rings a, b being of a size suitable for
the ends of the tapering glass strips c to fit in. The bottom ring b is fixed by tho
radial arms e, c to the central gas pipe f the burner of which is situated below the
open bottom of the lamp body as represented in Figure 5 and the top ring a is
secured to the central gas pipe f in the manner herein before described with respect
to Figures 1. 2. 3 and 4 for gripping the ends of the strips of glass between the
top and bottom rings a, b.
Figure 8 represents in side elevation a modification of the last described
rrangement. In this arrangement the inclined and tapering strips of glass caro
used in combination with the glazed bottom r of the body of the lamp. The top
ing a is fixed by the arms p, p to the outer frame q of the lamp and the bottoin
ing b to the bottom of the said outer frame q. The said bottom ring b also carries
he glazed frame 7 constituting the bottom of the lamp.

invention and in what manner the same is to be performed I declare that what
I claim is of "Improvements in hall lamps and other lamps"
