Year: 1880

page_text: LETTERS PATENT to William Henry Thompson and David Thompson, of Queen
Square, Leeds, in the County of York, Plumbers and Glaziers, for an Invention
of "IMPROVEMENTS IN GLAZING VERTICAL AND SLOPING SURFACES FOR
HORTICULTURAL, RAILWAY, AND OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said William Henry Thompson
and David Thompson at the Office of the Commissioners of Patents on the
13th October 1880.
WILLIAM HENRY THOMPSON and DAVID THOMPSON, of Queen Square, Leeds,
in the County of York, Plumbers and Glaziers. "IMPROVEMENTS IN GLAZING
VERTICAL AND SLOPING SURFACES FOR HORTICULTURAL, RAILWAY, AND OTHER
PURPOSES."
The object of this Invention is the glazing of vertical and sloping surfaces in a
rapid, substantial, and water-proof manner, without the use of putty or other plastic
or adhesive material, and it may be thus described :—
We first prepare, either by cutting or casting, the plates or panes and half panes
of glass in diamonds or squares to be fixed as diainonds, and we perforate these
plates or panes near one of the angles or points with a hole about five-sixteenths
or three-eighths of an inch diameter.
We next construct a number of brass, copper, or other metal holders or supports
in the form of pins, screws, clamps, or other convenient method or arrangement to
suit the before-named perforations, and admit a washer of india-rubber, leather, or
other soft material between the glass and the head or nut, or both, as the case may
require, the inner end, by preference, of these holders being formed by bending or
"notching," in such a manner as to clip or otherwise lay hold of the laths, strips,
upright bars, or other fixed part of the frame or building, whereon, by means of
these holders or carriers, the glass is to be supported, the only peculiarity
we require in the laths or strips being the bevelling, at an angle of about
forty-five degrees of the side or surface, against which the pulling edge or face of

page_text: the said holders or carriers rests or is in contact with when the glazing is
completed.
In laying or fixing the glass we prefer to keep the before-named perforations at
the bottom point of the diamonds, and to so space and arrange the panes that an
uniform margin or "overlap" shall "bound" each diamond; and also that by the
hooked or notched holders and the overlap of the panes the whole shall be held
firmly and completely together.
By the foregoing arrangement water upon the outer surface is led to the lower
points of the diamonds or panes, and snow, in thawing, has not sufficient support
from projections to be productive of damage; also, as the holders are free to slide
upon the bevelled edge of the laths, no evil effects will result from the expansion
or contraction of the glass.

Patent Office on the 13th April 1881.
WILLIAM HENRY THOMPSON and DAVID THOMPSON, of Queen Square, Leeds,
in the County of York, Plumbers and Glaziers. "IMPROVEMENTS IN GLAZING
VERTICAL AND SLOPING SURFACES FOR HORTICULTURAL, RAILWAY, AND OTHER
PURPOSES."
The object of this Invention is the glazing of vertical and sloping surfaces in a
rapid, substantial, and water-proof manner, without the use of putty or other plastic
or adhesive material, and it may be thus described.
We first prepare, either by cutting or casting, the plates or panes and half panes
of glass in diamonds or squares to be fixed as diamonds, and we perforate these plates
or panes near one of their angles or points with a hole about five-sixteenths or three-
eighths of an inch diameter. We next construct a number of brass, copper, or other
metal holders or supports, in the form of pins, screws, clamps, or other convenient
method or arrangement, to suit the before-named perforations; and admit a washer
of india-rubber, leather, or other soft material, between the glass and the head or nutt,
or both, as the case may require, the inside end or portion of these holders, by
preference, being formed so as to possess a considerable surface "one way," and this
at an angle of about forty-five degrees from the pins or screws, to clip or otherwise
rest upon or lay hold of the laths, strips, bars, or other fixed part of the frame, roof,
or building, whereon, by means of these holders or carriers, the glass is to be fixed
and supported, the only peculiarity we require in the said laths or strips being the
bevelling, at a similar angle to the before-described bearing surface of the pins of
the side or surface, against which the pull of the pins is received when the glazing
is completed.
In laying or fixing the glass we prefer to keep the before-named perforations at
the bottom point of the diamond panes or "squares" of glass, and to so space and
arrange them that an uniform margin or "overlap" shall "bound" each diamond;
and also that by this over-lap and the tightening action or tendency of the screws
or pins upon the laths, the whole shall be held firmly and completely together.
By the foregoing construction and arrangement water upon the outer surface is
led to the lower points of the diamonds or panes, and snow, in thawing, has not
sufficient support from projections to be productive of damage; also, the holders
being free to slide upon the bevelled edge of the laths, no evil effects will result
from the expansion or contraction of the glass.
In the accompanying illustrations, Figure 1 is a plan or face view of the glazing;
Figure 2 is a section of the same, showing the bevelled laths and holders; and
Figure 3 is a perspective elevation of a complete building glazed in accordance with
our Invention.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried into
effect, we wish it to be understood that we do not confine or restrict ourselves to
the precise details or arrangements which we have described or referred to, as many
modifications and variations may be made therefrom, without deviating from the
principles or main features of the said Invention, but what we consider to be novel
and original, and therefore claim as the Invention secured to us by the herein-before
in part recited Letters Patent is,―
The use, in glazing without putty or other plastic material, of perforated diamond
shaped panes or plates, secured through these perforations by self tightening screw
or other equivalent holders, pins, or catches, furnished with elastic washers or

page_text: cushioning rings, and clipping or otherwise resting upon or against bevelled wedge-
shaped laths or bearers, as or after the manner of the foregoing description.
In witness whereof, we, the said William Henry Thompson and David
Thompson, have hereunto set our hands and seals, this Eleventh day of
April, in the year of our Lord One thousand eight hundred and eighty one.
