page_text: I, ALEXANDER DRUMMOND, of 35 Montrose Street, in the City of Glasgow,
Glass Merchant, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide simple and effective means for securing
the sheets or panes of glass to the astragals or sash bars of glazed structures.
For that purpose I secure to the upper side of the ordinary astragal or sash bar
a central ridge or feather of wood or other material, the sides of which are clothed
with a strip or strips of sheet lead, or other ductile inetal, which is folded down
upon the edges of the glass sheets to secure them in place on the supporting
astragals or sashbars. The sheet lead may be fitted as a single strip on each ridge
piece or feather to cover the two vertical sides and lower edge where it may be
tacked on to the feather, or a single strip may be tacked on or secured in grooves
on each side of the feather or ridge piece. The glass is laid or rested on the
astragal or sash bar with the edges of the sheets abutting against the lead clad
feather, and the strips of sheet lead. are then folded over the edges of the glass.
The feather when made of wood may be encased in zinc or lead to protect it from
moisture or the sheet lead may be fitted over the top and sides of the feather and
doubled up at the lower edges in which case the doubled strips are afterwards
folded down over the edges of the sheets of glass to retain them in place. The
feathers or ridge pieces may be clad with lead as described and may be kept in
stock and supplied for use to secure glass sheets to astragals of any form capable of
supporting the glass, the ridge pieces being nailed or otherwise secured to the
astragals before fitting the glass in place.

page_text: I, ALEXANDER DRUMMOND of 35 Montrose Street, in the City of Glasgow,
Glass Merchant, 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:-
The object of my invention is to provide simple and effective means for securing
the sheets or frames of glass to the astragals or sashbars of glazed structures.
For that purpose as seen by figure 1 of the annexed drawings I secure to the
upper side of the ordinary astragal or sash bar b, a central ridge or feather a of
wood or other material the sides of which are clothed with a strip c of sheet lead
or other ductile metal which is folded down upon the edges of the glass sheets d, to
secure them in place on the supporting bars or astragals b.
Instead of securing the ridge or feather a to the top of the astragal as at figure 1
it may be recessed into the upper side as shewn at figure 2 of the drawings.
Figures, 3, 4, 5, 6 and 8, are detailed cross sections shewing various modes of
fitting the sheet lead or other ductile strip c to the central ridge or feather a. As
seen by figure 3 it may be fitted as a single strip so as to cover the bottom of the
ridge or feather, the strip being secured to the bottom of the feather by tacks fand
from thence projected upwards on both sides or as seen by figure 4 a separate
strip c may be tacked to each side of the ridge or feather the lower edges of the
strips being bent under the bottom of the ridge or instead of being so bent grooves
may be made in the sides of the ridge or feather as seen at 1, figure 5 and the ends
of the strips c inserted thereinto and tacked or otherwise held in position, or as seen
at figure 6 a groove or channel g may be cut out of the top of the ridge or feather a
and the strips inserted thereinto or a single strip folded at the middle as on the
figure may be so inserted, the glass whichever arrangement is adopted being laid on
the astragals with the edges of the sheets against the ridge or feather a, and the
strips of lead then folded down over them.
When the ridge or feather is made of wood it may have a separate zine or lead
casing placed over it as at i, figure 7 to protect it from moisture, or as seen at
figure 8, the lead strip o for holding the glass may for that purpose be folded over
the top and sides of the feather a, and doubled back at the bottom the doubled
ends being used to retain the glass in place.
The feathers or ridge pieces constructed and provided in any of the modes
hereinbefore described may be kept in stock and supplied for use to secure glass
sheets to astragala of any form capable of supporting the glass the ridge pieces a
being nailed or otherwise secured to the astragals before fitting the glass in place.

page_text: 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
1. The combination of an astragal or sash bar and a ridge or feather clad or
provided with sheet lead or other ductile strips as means of securing glass,
substantially as described with reference to the drawings annexed.
2. In glazing, the ridge or feather a clad or provided with sheet lead or other
ductile strips, substantially as described with reference to the accompanying
drawings.
