WILLIAM WILLIAMS Box, of Crayford, in the County of Kent. 'IMPROVEMENTS
IN SECURING GLASS AND OTHER SURFACES IN FRAMES FOR LAMPS, LANTERNS, AND
OTHER ARTICLES AND STRUCTURES."
The object of my Invention is to dispense with the use of putty, so that lamps,
for example, may be repaired by unskilled workmen, and at the same time the
frames are not injured by the continued chipping off of the hard putty.
According to one arrangement of my Invention the corners of the frame are
made with angle pieces, and the base thereof with diagonal pieces extending
nearly up to the angle pieces; the glass cut to the exact size of the frame as usual
is placed against or in the angle pieces, and to secure the glass I provide a strip of
angled metal to fit against the same, and to grip the two adjacent plates of glass
at one and the same time. The angle strips of metal are beld in position by being
slipped under a loop or staple at the top of frame, and by being inserted at
bottom between the diagonal pieces and angle corner-pieces in the space there left
for their reception. A hooked projection is connected to the angle strips so as to
take hold of same to put them into position, and to remove them when required to
insert a new pane of glass.
Instead of the diagonal pieces I in some cases dispense with them and use loops
or their equivalents instead. The bottom frames are secured by pins inserted in
the diagonal pieces, and the panes themselves rest upon flanges formed by the base
of the diagonal pieces aforesaid. By taking out the pins the panes can be
replaced.
The Invention further consists in securing the top glasses or plates by inserting
the same into grooves or recesses formed in the frames for that purpose, and there

the frames, and when turned in the contrary direction the said panes are free to
be removed. The clips may be made of soft metal, such as copper, so as to be
easily fastened and unfastened as desired. The groove or recess is preferably made
with a wire edge and groove so that the glass rests on wire, and a space is then
formed for the passage of water. I glaze or enamel these plates on the underside
where desired so as to act as reflectors, but I lay no claim to such glazing or
enamelling except when used in combination with arrangement described for
securing the same into the frames as aforesaid. There is a space between the top
glass and lower left for the admission of air, which tends to keep cool the inside of
the lamp.
The panes are inserted in the doors in grooves by slipping them into same, and
securing the glass by pins passed through the framing at top, or by any other con-
venient mode of fastening.
The glazing of windows can be effected, according to my Invention, as before
described, but the angle holding pieces must then be secured by passing them
through apertures in the beading frames. This arrangement is particularly applicable
for the insertion of coloured, stained, or other decorated glass over ordinary glass;
the apertures are not required if the angle pieces are made in two parts, then they
can be secured by loops.

"IMPROVEMENTS
IN SECURING GLASS AND OTHER SURFACES IN FRAMES FOR LAMPS, LANTERNS, AND
OTHER ARTICLES AND STRUCTURES."
The object of my Invention is to dispense with the use of putty, so that lamps,
for example, may be repaired by. unskilled workmen, and at the same time the
frames are not injured by the continued chipping off of the hard putty.
According to one arrangement of my Invention the corners of the frame are
made with angle pieces, and the base thereof with diagonal pieces extending nearly
up to the angle pieces; the glass cut to the exact size of the frame, as usual, is
placed against or in the angle pieces, and to secure the glass I provide a strip of
angled metal to fit against the same and to grip the two adjacent plates of glass at
one and the same time. The angle strips of metal are held in position by being slipped
under a loop or staple at the top of frame, and by being inserted at bottom between
the diagonal pieces and angle corner pieces in the space there left for their recep-
tion; a hooked projection is connected to the angle strips so as to take hold of
same to put them into position, and to remove them when required to insert a new
pane of glass. The bottom panes are secured by pins inserted in the diagonal
pieces, and the panes themselves rest on flanges formed by the base of the diagonal
pieces aforesaid. By taking out the pins the panes can be replaced.
The accompanying Drawings illustrate a convenient manner of carrying my
Invention into effect.
Figure 1 is an external side elevation; Figure 2 is a sectional elevation; Figure 3
is a top plan; Figure 4 is a horizontal section through line x, y, of Figure 1; and
Figures 5 and 6 are detail views to be hereafter referred to. Similar letters of
reference refer to like parts in all the Figures. a, a, are the angle pieces of the
frame, and b, b, the diagonal pieces on the base; c, c, are the metal angle pieces
which fit against the glass in the frame; d, d, are the loops or staples at top, under
or into which the angle pieces c, c, are passed (see Figure 5), and at bottom between
the diagonal pieces b, b, of the frame; e, e, are the hooked projections on the pieces
c, c, for raising or otherwise adjusting the position of the said metal angle pieces c, c;
ff, are the pins or studs inserted in the diagonal pieces b, b; and g, g, are the
lower panes of glass (see Figure 6) of the lantern; it is under the pins f, f, that the
lower glasses are slipped, the lower surface of the said glass resting on the lower
angle frame piece a, a, as for the side frames. Loops, or their equivalents, may
sometimes be used instead of the diagonal pieces.
The metal movable angle pieces c, c, may be secured to the frame at the bottom
of the angle piece by having a tapped piece of wire to pass through a hole at
bottom, with nut to hold the angle piece in place, and thus to prevent it being

projections I make sometimes the same curved so as not to offer any impediment
to the cleaning of the frame.
The Invention further consists in securing the top glasses or plates by inserting
the same into grooves or recesses formed in the frames for that purpose, and there
securing them by studs or clips which when turned in one direction hold or support
the glass or plates, and when turned in the contrary direction the said plates are
free to be removed. The clips may be made of soft metal, such as copper, so as to be
easily fastened and unfastened as desired. The groove or recess is preferably made
with a wire edge and groove, so that the glass rests on the wire, and a space is
then formed for the passage of water. I glaze or enamel these plates on the under-
side where desired so as to act as reflectors, but I lay no claim to such glazing or

securing the same into the frames as aforesaid.
h, h, are the grooves or recesses into which the top glasses are slipped; i, i, are
the top glasses; k, k, are the clips or studs for securing the glasses i, i, into the
grooves h, h.
There is a space between top glass and lower left for the admission of air,
as shewn by the arrows, Figure 2, which tends to keep cool the top glass
or plate.
The panes are inserted in the doors in grooves by slipping them into same, and
securing the glass by pins passed through the framing at top, or by any other
convenient mode of fastening.
The glazing of windows can be effected, according to my Invention, as before
described, but the angle-holding pieces must then be secured by passing them
through apertures in the beading frames, or other convenient mode of fastening.
This arrangement is particularly applicable for the insertion of coloured, stained, or
other decorated glass over ordinary glass; the apertures are not required if the
angle pieces are made in two parts, then they can be secured by loops.
Figures 7, 8, 9, and 10 show arrangements how this may be accomplished. In
Figure 7 the glass is secured by clips on each side of the pane, and fastened to the
glazing bars by screws or pins, or other device; when it is desired to replace a
pane only one clip has to be removed. In Figs. 8, 9, and 10 an angle frame is
shown corresponding in shape with the pane of glass, and the glazing bar is made
as shown in section at Figure 9; the angle pieces in these examples are provided
with pegs or overhanging pieces by which they are secured to the glazing bars, and
the said angle pieces may be lined with india rubber, velvet, or other suitable
material.
Having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I am aware it is not new to glaze lamps
without the use of putty. I do not, however, use any specially constructed frame,
the ordinary lamp frames being available. I am also aware that it is not new to
place reflectors in the upper parts of lamps, but I claim as my improvements in
securing glass and other surfaces in frames for lamps, lanterns, and other articles
and structures,―
First. The employment of movable angled metal strips c, c, placed on the inside
of the glass frame for gripping the edges of the two adjacent plates of glass, the
said strips being secured in and by the employment of, and combination there with,
of diagonal pieces b, b, and loops d, d, or their equivalents, all substantially as and
for the purposes herein before described and illustrated with reference to the accom-
panying Drawings.
Second. The node and means for securing panes of glass in the base of lamps
and lanterns without putty, substantially as described with reference to the accom-
panying Drawings.
Third. The mode and means described for securing plates in the top frames of
lamps or lanterns, in and by the combination of grooves or recesses h, h, or
their equivalents, with clips, studs, or their equivalents k, k, substantially as set
forth.
In witness whereof, I, the said William Williams Box, have hereunto set
my hand and seal, this Twenty second day of April, in the year of our Lord
One thousand eight hundred and eighty.
