AN IMPROVED SYSTEM OF GLAZING ROOFS AND OTHER PARTS OF BUILDINGS, ESPECIALLY ADAPTED FOR HORTICULTURAL STRUCTURES
Year: 1884

page_text: I HENRY THOMAS CREWE of 17 Sunning Hill Road, Lewisham, Kent, Builder's
Clerk of Works and Surveyor, do hereby declare the nature of my said invention
for "AN IMPROVED SYSTEM OF GLAZING ROOFS AND OTHER PARTS OF BUILDINGS,
ESPECIALLY ADAPTED FOR HORTICULTURAL STRUCTURES" to be as follows:-
The object of this invention is to so make the rafters and sash bars also the
frames that the panes of glass can be held in position by buttons or plates which
are capable of being slid upon screws or other kind of fastener for adjustment and
then secured. The rafters such as the intermediates for roofing have their upper
surfaces grooved in the direction of their length, the bottom of the grooves being
inclined from the centre towards the outer ribs on which the glass can rest but
with their side edges over lapping the ribs for the free passage of rain water and
that arising from condensation into the grooves. With the principal rafters and
sash frames of horticultural buildings I make the grooves on one side or on both
sides of a vertical bead according to the position they have to occupy.
The buttons or clips which I use with my rafters, frames, and bars, are stepped
and each one has a long slotted aperture with an enlarged end the slot being
through both the rise and the step to enable the clip to be slid up to the glass to
hold the upper end of two adjoining panes and the lower ends of the two panes
directly above them small lips being at the ends of the clips to bear upon the glass
to hold it firmly in place.
The clips may vary in shape and the slotted aperture may for the principal
rafters and sash frames be in the side portions or as found convenient.
The clips can be fixed with any degree of tightness and be slid along either to
secure or release the glass which can be entirely removed to permit of the bars,
rafters, etc. to be painted or for fresh panes to be put in for repairs or otherwise,
no putty, or other adhesive being required.

I HENRY THOMAS CREWE of 17 Sunning Hill Road, Lewisham, Kent, Builders
Clerk of Works and Surveyor, do hereby declare the nature of my said invention
for "AN IMPROVED SYSTEM OF GLAZING ROOFS AND OTHER PARTS OF BUILDINGS
ESPECIALLY ADAPTED FOR HORTICULTURAL STRUCTURES," and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:―
s
The object of this invention is to so make the rafters and sash bars also the
frames that the panes of glass can be held in position by metal buttons or plates
which are capable of being slid upon screws or other kind of fastener for adjust-
ment and then secured. The rafters such as the intermediates for roofing have
their upper surfaces grooved in the direction of their length, the bottom of the
grooves being inclined from the centre towards the outer ribs on which the glass
can rest but with their side edges overlapping the ribs for the free passage of rain
water and that arising from condensation into the grooves. With the principal
rafters and sash frames of horticultural buildings, I make the grooves on one side
or on both sides of the rebate according to the position they have to occupy.
The buttons or clips which I use with my rafters, frames and bars, are stepped
and each one has a long slotted aperture with an enlarged end the slot being
through both the rise and the step to enable the clip to be slid up to the glass to
hold the upper end of two adjoining panes and the lower ends of the two panes
directly above them, small lips being at the ends of the clips to bear upon the glass.
to hold it firmly in place and to allow for expansion and shrinkage.
The clips may vary in shape and the slotted aperture may for the principal
rafters and sash frames be in the side portions or as found convenient.
The clips can be fixed with any degree of tightness and be slid along either to
secure or release the glass which can be entirely removed to permit of the bars,
rafters, etc. to be painted or for fresh panes to be put in for repairs or otherwise,
no putty, or other adhesive being required.
The invention will be understood by reference to the annexed drawings in which
Figure 1 represents in plan and section a clip A and screw B for flat or upright
glazing or glazing ordinary rafters. Figure 2 is a perspective view of a similar.
clip. Figure 3 shows an angle clip for side glazing or principle rafters, one
application of it being shown at Figure 8. Figure 4 represents a form of clip
applicable to butt-joint upright flat glazing and Figure 5 an arrangement for main
rafters with ventilating openings. Figures 6 and 7 show examples of glazing a
common roof and upright bars respectively by means of clips, and suitable for small
greenhouses, pits &c. Figure 9 shows the clip applied to an ordinary rafter or bar.
It is obvious that wood or iron roofing or framing whether curved or flat may be
glazed by means of clips in a similar manner by merely modifying the shape of the
clip or bending it and using a suitable screw or its equivalent.

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 improved system or method of glazing roofs and other parts of buildings
especially adapted for horticultural structures hereinbefore set forth and shown.
2. The metal clip or button hereinbefore described and shown for the purpose
of glazing roofs and other parts of buildings and horticultural structures in the
manner set forth.
