page_text: LETTERS PATENT to John Henry Osborne, of Plymouth, in the County of
Devon, Painter and Glazier, for the Invention of "IMPROVEMENTS IN THE
METHOD OF SECURING PANES OF GLASS IN WINDOW SASHES, SKY LIGHTS, AND
OTHER FRAMES."
PROVISIONAL SPECIFICATION left by the said John Henry Osborne at the
Office of the Commissioners of Patents on the 23rd July 1879.
JOHN HENRY OSBORNE, of Plymouth, in the County of Devon, Painter and
Glazier. "IMPROVEMENTS IN THE METHOD OF SECURING PANES OF GLASS IN
WINDOW SASHES, SKY LIGHTS, AND OTHER FRAMES."
This Invention relates to improvements in the method of securing panes of glass
in window sashes, skylights, and in the sides and other parts of horticultural and
other buildings, and consists principally in the employment of strips of india rubber,
cork, or any other suitable soft elastic material, as a substitute for putty, whereby
the operation of glazing is greatly facilitated, whilst the panes of glass are arranged
in a perfectly secure and water-tight manner.
In the case of ordinary window-sashes that part of each bar against which the
edges of the panes of glass are to bear is made flat and is covered by a strip of india
rubber, cork, or other suitable elastic material, upon which the edges of the adjoining
panes of glass are placed in such a manner as to leave a small space between the
same; a similar strip of elastic material is then placed over the joint so formed, and
the whole is held in position by a bar or strip of metal which is placed over the last
mentioned strip of elastic material, and is secured by screws or bolts which pass
through the whole of the before mentioned strips, and between the edges of the
respective panes of glass, into the bar of the sash. Those edges of the glass which
are next to the frame of the sash are in some cases fitted into grooves in the latter
between two strips of elastic material, or they are made to bear against ledges

When-my-said.Invention is employed in connection with skylights, greenhouses,
and other frames where there are no cross-bars the strips of elastic material-upon
which the respective_panes-of-glass-bear are madé wedge-shaped, that is to say,
gradually-increasing-in-thickness from top to bottom, so as to allow of the necessary
overlapping-of-the panes of glass.__
The employment of my Invention as above described facilitates the operation of
glazing, and also-the-taking-out-and replacing of any of the panes of glass, whilst,
when arranged, the latter are held securely in a water-tight manner, and in such a
way as to permit of the expansion or contraction of the glass.

the said John Henry Osborne in the Great Seal Patent Office on the 23rd
January 1880.
JOHN HENRY OSBORNE, of Plymouth, in the County of Devon, Painter and
Glazier. IMPROVEMENTS IN THE METHOD OF SECURING PANES OF GLASS IN
WINDOW SASHES, SKY-LIGHTS, AND OTHER FRAMES."
My said Invention relates to improvements in the method of securing panes of
glass in window-sashes, skylights, and in the sides and other parts of horticultural
and other buildings, and consists principally in the employment of strips of felt, cork,
or any other suitable soft clastic material, as a substitute for putty, whereby the
operation of glazing is greatly facilitated, whilst the panes of glass are arranged in
a perfectly secure and water tight manner.
In the case of ordinary window sashes that part of each bar against which the
edges of the panes of glass are to bear is made flat, and is covered by a strip of felt,
cork, or other suitable elastic material, upon which the edges of the adjoining panes
of glass are placed in such a manner as to leave a small space between each pane ;
a similar strip of elastic material is then placed over the joint so formed, and the
whole is held in position by a bar or strip of metal which is placed over the last
mention strip of elastic material, and is secured by screws or bolts which pass
through the whole of the before mentioned strips, and between the edges of the
respective panes of glass into the bar of the sash. Those edges of the glass which
are next to the frame of the sash are in some cases fitted into grooves in the latter
between two strips of elastic material, or they are made to bear against ledges
provided with strips of elastic material, and secured in a manner similar to that
herein before described.
When my said Invention is employed in connection with skylights, greenhouses,
and other frames in which there are no cross bars, and where the lower edge of one
pane is lapped over the upper edge of the next in the same vertical line, the strips
of elastic material upon which the respective panes of glass bear are made wedge
shaped, that is to say, gradually increasing in thickness from top to bottom, so as to
allow of the said overlapping.
I will now proceed to refer to the accompanying Drawing, from which the nature
of my said Invention will be more clearly understood. The same letters of reference
indicate like parts in the several Figures. Figure 1 is a cross section of a bar of a
window sash, showing the edges of two panes of glass, the strips of elastic material,
the bar or strip of metal, and the screw for securing the whole to the bar. Figure 2
is a front view of a portion of a window sash, and Figure 3 is a section of the same
through the line B, B, Figure 2. Figure 4 shows the arrangement of the wedge
shaped strips of elastic material for skylights, greenhouses, and other frames, and
Eigure 5 is a front view of several panes of glass arranged in the manner lastly
hereinbefore referred to; and Figure 6 shows a cross section of a portion of a frame
of a window when the edge of the pane of glass is inserted into a groove therein
between two strips of elastic material.
A is the sash frame, B the bars thereof, C the panes of glass, D the lower strip of
elastic material, E the upper strip of elastic material; F is the bar or strip of metal,
and G are the screws or bolts.
The employment of my Invention as above described facilitates the operation of
glazing, and also the taking out and replacing of any of the panes of glass, whilst,
when arranged, the latter are held securely in a water tight manner in such a way
as to permit of the expansion or contraction of the glass.
Having thus described and ascertained the nature of my said Invention, and the
manner in which it is to be performed, I would observe in conclusion, that what I

page_text: consider novel and original, and therefore claim as constituting the Invention secured
to me by the said hereinbefore in part recited Letters Patent, are,-
The-improvements-in-the-method of securing panes of glass, substantially as and
for the purposes hereinbefore described and set forth.
In witness whereof,-1,-the-said John Henry Osborne, have hereunto set my
hand and seal, this-Twenty-second day of January, in the year of our Lord
One thousand eight hundred-and-eighty.
