PROVISIONAL SPECIFICATION.
Improvements applicable to Glazing Bars or Astragals for Roof
Lights and Windows.
I, PETER YOUNG LYLE, Secretary to The Pennycook Patent Glazing and
Engineering Company, Limited, 11, West Regent Street, in the County of the
City of Glasgow, North Britain, do hereby declare the nature of this invention to
be as follows, that is to say :-
My said invention has for its object by means of an improved appliance to bold
the glass sheets of roof lights and windows in position in a more secure and
satisfactory manner than heretofore.
In carrying out my invention any suitable known form of glazing bar or
astragal may be used having a projecting web or equivalent part usually covered,
or partly covered, with lead or other suitable metal or alloy arranged to cover and
hold down the glass.
When the glass is in position the lower edge of each pane overlaps the upper
edge of the next lower pane, and to prevent each pane from slipping downwards
or otherwise moving a small hole or slot is punched or cut in a suitable position
through the lead and through the web of the astragal or bar. Small clips of brass,
tin, lead, or any suitable metal or alloy are made with a groove or part to ultimately
fit on to the top of the web of the astragal or bar an inwardly projecting tooth
being formed on each clip at each side of the groove to fit into the hole or slot in
each side of the web of the astragal or bar but when the clip is being placed the
teeth are sufficiently apart to pass over the top of the astragal or bar. After
being placed the sides of the clip are forced towards each other so as to cause the
teeth to enter the hole or slot and thereby lock the clip in position. The clips are
applied to the bar in such positions that the lower edges of the several panes of
glass rest on them any possibility of downward movement of the glass being
thereby prevented.
Dated this Thirteenth day of September 1894.

COMPLETE SPECIFICATION,
Improvements applicable to Glazing Bars or Astragals for Roof
Lights and Windows.
I, PETER YOUNG LYLE, Secretary to The Pennycook Patent Glazing and
Engineering Company, Limited, 11, West Regent Street, in the County of the
City of Glasgow, North Britain, 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, that is to say :-
My said invention has for its object by means of an improved appliance to hold
the glass sheets of roof lights and windows in position in a more secure and
satisfactory manner than heretofore.
In carrying out my invention any suitable known form of glazing bar or
astragal may be used having a projecting web or equivalent part usually covered,
or partly covered, with lead or other suitable metal or alloy arranged to cover and
hold down the glass.

page_text: When the glass is in position the lower edge of each pane overlaps the upper
edge of the next lower pane, and to prevent each pane slipping downwards or
otherwise moving, a small hole or slot is punched or cut in a suitable position
through the lead or other covering metal and through the web of the astragal or
bar. Small clips of brass, tin, lead, or any suitable metal or alloy are made with
a groove or part to ultimately fit on to the top of the web of the astragal or bar
an inwardly projecting tooth being formed on each clip at each side of the groove
to fit into the hole or slot in each side of the web of the astragal or bar but when
the clip is being placed the teeth are sufficiently apart to pass over the top of the
astragal or bar. After being placed the sides of the clips are forced towards each
other so as to cause the teeth to enter the hole or slot and thereby lock the clip in
position.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing my improvements applicable to glazing bars
or astragals for roof lights and windows."
Figures, 1, and 2, are views, as taken at right angles to each other, and Figure, 3,
is a cross section of an astragal and showing the application of my clip.
Figures, 4, and 5, are views of one modification of the metal clip, Figures, 6,
and 7, being views of other modifications of the same.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
When the glass, A, is in position the lower edge of each pane overlaps the upper
edge of the next lower pane and to prevent each pane from slipping downwards
or otherwise moving a small hole or slot is punched or cut in a suitable position
through the lead or other covering metal, B, and through the vertical web, C, of
the astragal or bar, D. Small clips, E, of brass, tin, lead, or any suitable metal or
alloy are made with a groove, G, to ultimately fit on to the top of the web of the
astragal or bar, D, an inwardly projecting tooth, H, being formed on each clip at
each side of the groove to fit into the hole or slot in each side of the web, C, of
the astragal or bar, D, but when the elip is being placed the teeth, H, are
sufficiently apart (as shown in Figure, 4) to pass over the top of the astragal or
bar. After being placed the sides of the clip, E, are forced towards each other
by means of any suitable compressing instrument so as to cause the teeth, H, to
enter the hole or slot and thereby lock the clip in position. The clips, E, are
applied to the bar in such positions that the lower edges of the several panes of
glass rest against them, any possibility of downward movement of the glass being
thereby prevented.
The modification of the clip, E, shown in Figure, 6, is made to be used to
support the lowest pane of glass only, each side or leg of the clip being made to
extend to the bottom of the web, C, of the astragal, D.
The modification of the clip, E, shown in Figure, 7, is to be used only with an
exceptionally deep-webbed astragal or bar, D.
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 application to glazing bars or astragals for roof lights and windows, of a
metal clip adapted to fit on the web of the astragal and made with teeth to
engage in a hole in the astragal substantially as and for the purposes hereinbefore
described.
Dated this Sixth day of June 1895.
