Year: 1884

page_text: PROVISIONAL SPECIFICATION,
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 the said Invention for
"IMPROVEMENTS IN HALL LAMPS AND OTHER LAMPS " to be as follows:-
My invention consists of the improvements hereinafter described in connecting
together and supporting the glazed parts of hall lamps and other lamps.
I make or build up the glazed parts of the lamp of sheets or panes of by preference
plate glass and support the said sheets or panes and secure them together in the
following manner.
I support the junctions of the panes at their top and bottom corners by clips or
angular supports carried by cross or radiating arms on the central. pipe of the
lamp. The top clips after they have been engaged with the top corners of
the glass panes are fixed in their places by a screw arrangement on the central
rod.
Or in place of supporting the junctions of the panes at the corners thereof screw
connections situated a short distance from the bottom corners of the panes and
carried by the lower radiating arms of the lamp may be used the upper radiating
arms of the frame being connected with the upper parts of the middle of the panes
by similar screw connections In this case holes are drilled in the panes for
receiving the screw connections.
The sheets or panes of plated glass which I use may either be coloured or
colourless or painted and the edges of the said sheets 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.

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 connecting
together and supporting the glazed parts of ball lamps and other lainps.
I make or build up the glazed parts of the lamp of sheets or panes of glass, by
preference plate glass, and support the said sheets or panes and secure them
together in the following manner-I-support the junctions of the-panas-at their
top and bottom corners by clips or angular supports carried by cross or radiating.
arins on the centrul pipe of the lamp. The top clips after they have been engaged.
with the top corners of the glass panes are fixed in their places by a screw
-arrangement on the central rod.
Or in place of supporting the junctions of the panes at the corners thereof screw
connections-situated a sliort distance from the bottom corners of the panes and
carried by the lower radiating arms of the lamp may-be-used, the upper madinting
arms of the frame-being-connected with the upper parts of the middle of the panes
by similar screw connections. In this case holes are drilled-in-the-panes_for
receiving the screw connections.
The sheets or panes of plate glass which I use may either be coloured or colourless
or painted and the edges of the said sheets 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.
Figure 1 of the accompanying Drawings represents in side elevation a hall lamp
constructed according to my invention, in which lamp the junctions of the panes
or sheets of glass are supported at the top and bottom corners by angular metallic
clips or supports; Figure 2 represents in side elevation partly in section (with the
front pane removed) and Figure 3 in horizontal section the body of the lamp
drawn to a larger scale; Figure 4 represents partly in section and partly in
elevation the arrangement for securing the arms of the top clips to the central gas
pipe.
The saine letters of reference indicate the same parts in Figures 1. 2. 3 and 4.
a, a are the top angular clips or supports fixed at the outer ends of the four
radial arms b, b secured to the gas pipe e and c, c are the bottom angular clips or
supports fixed at the ends of the four radial arins d, d secured to the gas pipe c.
The radial arms b, b carrying the top clips a, a are fixed to the collar f which collar
is supported upon the adjustable screw nut g on the screwed end of the gas pipe e
the said collar f being fixed in its place by the second screw nut into which the
upper part e² of the gas pipe is screwed as seen in Figure 4; i, i are the panes of
glass the junctions of which are supported at their top and bottom corners by the

page_text: said angular clips a, a nnd c, c. The shape of the said clips is best seen in Figures 2
and 3. Each angular clip carries two stop pins k, (see Figuro 3) against which
"the inner faces of the panes i, i bear but I do not limit myself to the use of the said
stop pins k, k as a stop plate or rib may be connected to the clip for the same
purpose.
The manner in which the angular clips are made to embrace the junctions of the
panes i, i and thereby support and secure together the said panes is best seen in
Figures 2 and 3. It will be seen by an examination of Figure 3 that the abutting
odges of the panes i, i are so arranged as to lock the several panes in their places
in the angular clips.
The horizontal edges of the bottom corners of the panes rest upon the closed
bottoms of the clips c, c while the closed tops of the clips a, a pass over and
embrace the horizontal edges of the top corners of the panes (sce Figures 2
and 3).
In building up the glazed part of the lamp the sheets or panes of glass i, i are
first introduced into the bottom clips cc so as to support the bottom corners of the
panes, the said bottom clips being carried by the radial arms d, d fixed on the gas
pipe c. The collar supporting the arms b, b and top clips a, a is next placed on
the scrowed end of the gas pipe e and supported upon the adjustable screw out g and
fixed by the screw nut h. The top clips a, a are thereby made to engage with or
einbrace the top corners of the several panes i, i so as to secure them in their
places. The glazed body of the lamp is thus formed and the parts secured
together.
Figure 5 represents in elevation a hall lamp in which modified angular clips are
used; Figure 6 represents the top and bottom clips of the lamp without the
panes and Figure 7 represents a plan of Figure 6 with some of the parts omitted.
In this modification each of the angular clips or supports is composed of an
angle piece / fixed to the end of the radial arm and a separate removable parallel
angle piece m supported on the screwed end n of the arm, the said angle piece m
being fixed in its place by the ornamental screwed head p screwed on the screw n
at the end of the radial arm. In Figures 6 and 7 some of the removable angle
pieces mare omitted. The position of one of the panes when put in the clips
is indicated in dotted lines in Figure 7. The clips are concealed by the ornamental
coils or scroll pieces q applied to each of the radial arms of the top and bottom
clips.
The top and bottom corners of the several panes are secured in the modified
clips last described in the manner herein described with respect to the arrangement
Figures 1, 2, 3 and 4.
Figure 8 represents in side elevation and Figure 9 in horizontal section (taken
through the bottom connections) a hall lamp constructed according to my invention
in which lamp the panes are supported and connected to the radial arms by screw
connections; Figure 10 represents in section a portion of the lamp exhibiting
one of the top screw connections and Figure 11 represents one of the panes
detached.
The same letters indicate the same parts in Figures 8, 9, 10 and 11.
r, r are the bottom horizontal radial arms fixed on the central gas pipe e and 8, 8
are the top radial arms curved in the manner represented in Figure 8. The outer
end of each of the radial arms 7 and 8 is screwed with a hollow or concave screw
for receiving the screws of the screw connections herein after explained. In each
of the glass panes t of the lamp body semi-circular recesses u, u are made at
opposite edges and at a short distance from the bottom (see Figure 11) so that
when the several panes are fitted together circular holes are left at the junctions of
the panes near the bottoms thereof as seen in the horizontal section Figure 9. At
the middle line of each pane t and near the top thereof a hole v is made. Through
the bottom holes u, u in the panes t ornamental screws w are passed and take into
the screwed ends of the radial arms rir; and through the middle holes in the
panes screws ≈ are passed from the inside of the lamp and made to take into the

page_text: screwed ends of the curved arins 8, 8 (see Figure 10). In order to bind together
the junctions of the panes t at the bottom screw connections w w, angular clips y, y
having an ornamental figure are used, the said clips being fixed in their places and
: made to embrace the angles of the panes t, tin the manner seen in Figure 9.
Similar shaped plates but flat marked y³ are used at the top screw connections .

Having now particularly described and ascertained the nature of my said
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":
First Supporting and securing together the sheets or panes of glass forming
the body of the lamp by means of angular clips or supports applied at the top and
:bottom corners of the said panes, the said angular clips or supports being connected
to the radial arms fixed to the central gas pipe and applied to the said panes
substantially as herein before described and illustrated in Figures 1, 2, 3, 4, 5, 6
and 7 of the accompanying Drawings.
Secondly Supporting and-securing together the sheets or panes of glass forming
..the body of the lamp by means of screw connections carried by the radial arms of.
the lamp, the said screw connections being-situated at a short distance from the
bottom corners of the panes and also at the upper parts of the middle line of the-
panes substantially as herein before described and illustrated in Figures 8, 9, 10
and 11 of the accompanying Drawings.
