Sash Bar for Glass Roofing.
I, ARTHUR SUTTON DEACON, of 8, St. Peter's Road, St. Leonards-on-Sea, in
the County of Sussex, Commercial Traveller, formerly of 19, Hopton Road,
Streatham, in the County of Surrey, do hereby declare the nature of this inven-
tion 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 certain improvements in roof glazing and fittings
employed with so called sash-bars employed in such fittings.
In the following description reference will be made to the sheet of drawings
hereunto annexed and the same will be referred to by figures and letters like
parts being denoted by similar letters.
Fig. 1 is an isometric view showing section and projection lines of the fitting
and construction; Fig. 2 is a like view of a slightly modified form of the
invention. Fig. 3 is a detached view of an end shoe-plate to prevent the glass
slipping endways.
This is shown in dotted lines in Fig. 1 as in position.
The main feature of the invention is to construct a thoroughly water-tight
glass roofing.
"
"
The sash-bars employed are of specially rolled steel or iron bars such as
indicated at a, Fig. 1 of approximately cross form but with the shorter side
arms extremities a¹, projecting upwards to form a trough a², between same and
the upward projecting web a³, of the cross like sash-bar.
The sash-bar in Fig. 2 is shown with the lower web of the cross-like form
removed.

page_text: To the sash-bar, Fig. 1, a specially drawn lead cap or cover plate is applied
the same being constituted of the upper web cap portion b, the two side arms
covers and trough linings b', and the extention parts 63, covering the undersides
of the arm.
The covering portion 63, of the bottom web of the sash-bar is in
this case separate but is held up in place by the side edges of the cover plate.
In Fig. 2 this piece 63 is not required as the lower web of the sash-bar is not
used. For lighter constructions this form will be sufficient.
In order to prevent endwise slipping of the glass, end-shoe-plates c, Figs. 3
and 1, are applied and are pinned or bolted to and through the top-rib of the
sash-bar a.
The wing-pieces 6, of the lead sash-bar cap or cover are laid down flat to bed
or hold the sheets of glass when laid in position and an adhesive solution may
be used in order to assist in rendering the fitting perfect.
To reenforce the tight lay of these wing pieces 64, pins or plates of copper,
brass or other noncorrodable metal may be applied to the upper web or rib of
the sash-bar and their ends will take up position against the roll edge of said
wing-pieces 64.
In construction of large iron or wood roofs, end brackets are employed of cast
iron or the like, same being bolted or screwed to the ridge, purlins or plates as
case may be, with forked ends of the said brackets to receive, attach, or hold the
ends of the said sash-bars; and the holes in the ends of said sash-bars are
elongated or slotted to admit of expansion and contraction.
The lead capping of the sash-bars is equally adapted to wood sash-bars as to
sash-bars of steel or iron as previously directed.
By these means an absolutely water-tight roof is assured and maintenance in
matter of painting internally and externally is avoided.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improvements in the construction of sash-bars and fittings for glass
roofing, constructed, combined and operating, as and for the purpose herein set
forth and described in reference to the accompanying drawings.
Dated 28th May 1900.
