Improvements in Glazed Structures.
I, HORACE JOHN PULLEN BURRY, of Brookland, Sompting, Sussex, Market
Gardener, 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 :-
This invention relates to the glazing of roofs or structures to which it may be
applicable and it consists in the improvements hereinafter set forth.
The cross bars which support the horizontal edges of the glass, are made each
with a groove running along its lower side at a small distance from the edge of this
side and the upper face, the said groove being preferably rectangular in cross
section. The upper face of the bar is rebated along its upper lying edge and the
floor of this rebate is chamfered or bevelled off towards the upper side of the bar.
The depth of rebate at its shallowest part is as nearly as possible the same as the
thickness of glass employed for glazing, and the angle of bevel is sufficient to cause
the upper edge of the bevelled face to be at a slight distance from the under
surface of the glass when in its place with the upper edge of the glass in the
aforesaid groove on the under side of the bar next above. This forms when the
glazing is complete a V-shaped space between the under surface of the glass and
the upper surface of the bar, the apex being along the line of the lower edge of the
glass resting within the rebate.
This space serves to receive moisture which may condense and run down on the
under or inner side of the glass, an outlet for this moisture being found by a
suitable number of grooves or incisions made in the outer face of the bar and
running into the rebate.
The glass is retained from slipping out of the rebate by nails or screws with
sufficiently broad heads driven or screwed into the bar so that the heads overlap
the edge of the glass.
This invention is illustrated in the annexed drawing in which Fig. 1 is a sectional
view of a portion of roof, and Fig. 2 is a plan view thereof.
A is a rafter. B a bar or batten secured thereon in the usual way. C is the
glass. is the rectangular sectioned groove along the lower side of the bar, this
groove being intended to receive the upper edge of the sheets of glass. c is the
rebate with bevelled floor c forming the recess under the glass when the latter is
inserted as shown in Fig. 1. D are the nails for securing the glass in place.
E are the incisions which may be made by two saw cuts in general prolongation of
the plane of the bevelled floor c to run out the condensed water from the recess
aforesaid under the glass.
The side edges of the glass will meet with a simple butt joint that is to say are
simply laid edge to edge.
No putty need be used in this glazing.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, 1 declare that what
I claim is :-
In a glazed structure cross bars of wood or metal B having a groove c on the
one side and rebate c¹ with bevelled floor c³ at the edge of the other side together

page_text: with incisions E leading therefrom in combination with sheet glass laid with respect
to said bars and secured substantially as and for the purpose described.
