PROVISIONAL SPECIFICATION.
An Improved Method of Glazing Roofs and the like.
FRANK COLLINSON and EDWIN COLLINSON 43 Arkwright Street, Nottingham
County of Nottingham Painters and Glaziers do hereby declare the nature of this.
invention to be as follows:-
The object of the present invention, is to provide a method of glazing without
the use of rebates, the glass resting on the surface of. woodwork or other material
composing the roof or other part of building or construction, entirely covering the
rafters, thereby,.leaving no woodwork or other material exposed to the weather.
This we do after the following manner. Using rafters or purlins of any pattern,
mould, or design, for convenience or ornamentation, which are not rebated in the
usual manner for glazing with putty, the panes of glass being placed-diagonally on
the surface of rafters or purlins, each pane overlapping the panes of glass
immediately below it, and being secured to the rafters or purlins, by clips of
copper, or other suitable metal.
By glazing roofs in the manner above described a perfectly water-tight roof is
secured, a great saving in the cost of first construction of roof, and afterwards in
maintainence and repairs, no painting being required on the outside of roofs.
Panes of glass may be replaced from the upper or under sides of roofs in much
less time than by the old method of glazing with putty.

COMPLETE SPECIFICATION.
An Improved Method of Glazing Roofs and the like.
We FRANK COLLINSON and EDWIN COLLINSON, 43 Arkwright Street,
Nottingham, Painters and Glaziers, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows in plan portion of a roof, skylight or like surface, glazed
according to our improved method.
Figure 2 shows a longitudinal sectional view of the same on the line A. A.
Figure 1.
Figures 3 show a plan and edge view of one of the metal clips hereafter
referred to.
Instead of forming rebates on the rafters and purlins of roofs to receive the
panes of glass and securing them with putty, the whole of the wood work or other
material forming the rafters B, purlins C, and wall plate C' have their upper or
outer surfaces formed flush and covered with panes of glass D placed diagonally,
each pane having its lower edges overlapping the upper edges of the panes of glass
immediately below it. Each pane being secured to the rafters, purlins, or wall
plate by clips E of copper or other suitable metal, each held in position by a nail
or screw.
The side edges of roofs or skylights may be finished to overlap as shown at the
left edge of Figure 1. Or the edges may terminate in a groove or on a rebate as

page_text: shown at the right edge of Figure 1, and be made water tight by putty joints, or
with lead or zinc flashings in the usual way.
Our improved method of glazing enables us to dispense with vertical, horizontal,
or diagonal gutters, and forms a perfectly water tight roof.
Panes of glass may be replaced from the upper or under side of the roof in much
less time than by the old method of glazing with putty.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved method of glazing roofs, substantially as described and
illustrated in the drawings annexed.
