Improvement in Roof Glazing.
I HENRY EDWARD PEACH of 33 Claremont Road Birkdale Southport in the County
of Lancaster Architect do hereby declare the nature of this invention to be as
follows:-
I form expansion and contraction bars of either metal or wood; these are placed
along the edges of the panels of glass and are filled with putty or other suitable
substance; in fixing the said bars, a space is allowed between them, in order to allow
for expansion and contraction under variations of temperature. The expansion &
contraction bars are secured to any ordinary skylight sash bar of either wood or metal
by means of screws or bolts passing through metal cappings.
Dated this Seventh day of February 1887.

1, HENRY EDWARD PEACH of 33 Claremont Road, Birkdale, Southport in the
County of Lancaster, Architect do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
I form expansion and contraction bars of either metal or wood which are placed
along the edges of the panes of glass and filled with putty or other suitable cementing
substance. In fixing the said bars a space is allowed between them in order to
permit expansion and contraction under variations of temperature.
The said expansion and contraction bars are secured to any ordinary skylight
sash-bar of either wood or metal by means of screws or bolts passing through metal
cappings.
On the accompanying drawing Figs. 1 and 2 represent transverse sectional views
of metallic sash-bars with my improved system of glazing applied thereto. Fig. 3
illustrates the same system applied to a wooden sash bar.
In all the views a is the sash-bar say of a sky-light, conservatory or other glazed
structure and bb are the sheets of glass. The edges of these glass-sheets bb are in
accordance with my invention supported in sheet metal expansion and contraction
bars cc which are placed along the edges of the panes of glass and filled with putty
or other suitable plastic substance d d. It will be observed that a space e is allowed
between the inner upright surfaces of the two bars cc to allow for expansion and
contraction under variations of temperature and that for this purpose the bottoms
of the said bars are flattened and thus capable of sliding to and fro upon the sash bar.
And in order to form a cover enclosing both bars cc and the space between them
and at the same time secure the bars cc in position with facilities for lateral sliding as
aforesaid I employ a metallic capping which in the case of Fig. 1 is secured to the
web a' of thei sash bar a by set-screws 9 9 screwing into the opposite extremities of a
transverse metallic ferrule h screwed to the sash-bar and in the case of Figs. 2 and 3
is secured by a screw i screwing direct into the top of the sash bar.
I would here observe that in the drawing I have illustrated sheet metal expansion
and contraction bars cc, but it will be apparent that the same may be constructed of
wood or other suitable material grooved longitudinally to receive the edges of the
glass bedded in putty or other suitable plastic material as aforesaid.
Having thus particularly described and ascertained the nature of my said invention
together with the best method with which I am acquainted for carrying the same into
practical effect I declare that what I claim is
:-
1st. The improvements in roof glazing substantially as and for the purposes berein-
before described.

page_text: 2nd. In the glazing of roofs the employment of expansion and contraction bars to
support the edges of the glass imbedded in plastic material and the modes of
protecting and securing such bars in position upon the sash-bar substantially
as and for the purposes herein before described and illustrated on the accompanying
drawing.
3rd. The combination and arrangement of parts consisting of the improved bars cc
and metal capping constituting the improved system of roof-glazing substantially
as hereinbefore described and illustrated on the accompanying drawing.
