PROVISIONAL SPECIFICATION.
A Method of Glazing for Horticultural or other Purposes by Securing
the Glass without the use of Putty or Metal Strips.
I, ROBERT MURRELL, of The Chestnuts, Sunbury-on-Thames, in the County of
Middlesex, Nurseryman, do hereby declare the nature of this invention to be as
follows:-
To the sash frames are secured strips of material "stepped" at suitable distances
along its length to receive and form a support for the ends of the glass panes.
These "steps
cause the strip to assume the form of a shallow rachet in which the
glass rests.
Thus the pane which is inserted in one step finds a seat at the sides upon the strip
and terminates at the following step overlapping the next pane to prevent the
entrance of rain etc.
After the panes have been placed in position they are secured by placing a second
length of the strip over the edges, the "steps" in this second strip filling the spaces
formed by the overlapping of the glass.
The second strip being then secured by screws or other suitable means, the whole
is firmly fixed and rattling &c. prevented. The material of which the strips are
formed consists of some weather resisting substance, such as roofing-felt, asbestos,
india rubber "papier-maché" &c. or the sash frames themselves may be constructed
wholly of the material.

COMPLETE SPECIFICATION.
A Method of Glazing for Horticultural or other Purposes by Securing
the Glass without the use of Putty or Metal Strips.
I, ROBERT MURRELL, The
66
Chestnuts," Sunbury-on-Thames, Nurseryman,
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 :-
My invention relates to glazing for horticultural or other purposes and consists of
a method of securing the glass without the use of putty or metal strips.
To the sash bars are secured strips of material "stepped" at suitable distances
along its length to receive and form a support for the side edges of the glass.
Similar strips are after the insertion of the glass inverted and superimposed over
the same and secured by placing a strip of wood or metal over the whole and fixing
the same with screws or clips.
"
The before mentioned stepped strips are composed of papier machie com-
pressed cork, canvas, felt, india rubber etc. etc. and the ", steps in the same cause
them to assume the shape of a shallow ratchet. A certain width is preferably left
in the centre of the strip of a constant thickness to prevent the lateral displacement
of the glass.
The construction of the strips and the mode of application will be more readily
understood by reference to the accompanying drawings in which similar reference
letters indicate similar parts.
Fig. 1, shews a front, Fig. 2, a side and Fig. 3, an end elevation of the
66 stepped" strip.

page_text: Fig. 5, shews a piece of the roof with the glass applied according to the
invention.
The strip A is attached to the sash bars and is furnished with the steps b, b
at each of its edges which steps serve to support the end edges of the glass
panes C.
The centre of the strip is preferably left of a constant thickness, as shown to
prevent the lateral displacement of the glass.
The glass having been inserted in its proper position its edges are covered and
secured by the superposition of a similar strip (Fig. 4) which locks the edges of the
glass. The strip is secured in its position by placing over the whole the metal or
wood strip D secured by the use of screws (eylet or others) which pass through the
centre of the strips and hold the glass in an airproof and watertight joint.

+
It is of course obvious that the sash bars themselves may be stepped to obviate
the use of the under strip and I do not 'therefore confine myself to the use of the two
strips but
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The method of glazing without the use of putty or metal strips by means of
the employment of stepped strips of material with or without the conjunction
of steps on the sash bars substantially and for the purpose as hereinbéfore
described.
