COMPLETE SPECIFICATION.
Improved Method for Glazing Greenhouses, Railway Stations, and
the like.
J, JOSIAH QUERTIER of St. Aubin, Burnaby Road Alum Chine Bournemouth,
Hants, Grape and Tomato Grower, 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 :-
My invention relates to structures where glass is used for the outside covering.
The framework, that is, the rafters and sash bars are so made that when the glass
is bedded on them with putty & nailed or screwed down the only space left
exposed to the weather is the putty pressed up between each row of glass the
thickness of my special nail which is driven between each row of glass into the
centre of rafter or sash bar the top or holdfast portion of nail clenching the glass
on both sides. If preferred for wide structures the rafters may be rebated in the
usual way leaving some wood projecting above the glass to enable getting on the ·
roof for repairs when necessary.
This I do by having the sash bars & rafters made square or flat on the upper..
surface and placing them from the ridge to the plate at distances of about of an
inch from centre to centre over the width of the glass to be used, that is, I allow
just room enough between each row of glass from ridge to plate for my special nail-
hold fast to be driven home, the hold fast portion gripping the top edges of glass on
both sides at the same time, the glass having been previously bedded in putty. If
preferred the edges of the glass may be brought close together by chipping or
cutting it a little where the nails pass through to rafters or sash bars. On each
side of rafters & sash bars I make a groove to receive any condensation arising on
the glass which is carried off down to the bottom plate, thus avoiding a drip.
The nails I make of suitable metals, brass, copper or zinc the top or hold fast
portion of soft metal preferably lead, in suitable shapes, either round, oval,
triangular or T shaped with smooth or ornamental surface the underpart hollowed
out or bell shaped, into which I make a hole to receive the nail or screw, or they
may be moulded to the nails, nail & holdfast combined. The holdfast portion of
nail is made large enough to hold down the glass in its place on both sides of nail.
For the bottom corners of the panes of glass where they overlap I form a heel to
holdfast at one end to grip the bottom edge of the glass to avoid its slipping down
the bars. For the bottom row of glass where it hangs over the plate into the
gutter I lengthen the holdfast portion of nail & form a heel at the end as above to
keep the glass in position over the gutter.
The nail & holdfast may be made in one or two parts of the same or different
metal, the hold fast portion with a hole in to insert the nail (or screw if preferred)
or made in one, the hold fast moulded on the nail.
For structures where iron rafters or bars are used, screws or bolts would be used
instead of the nail portion, holes being drilled in rafters & bars to receive them.
In order that my invention may be more fully understood I will now proceed to
describe the accompanying sheet of drawings in which the like letters of reference
indicate the like parts throughout.

:
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what
I claim is :-
ག
•
1. Improved method of glazing for greenhouses conservatories, railway stations
& the like all as herein described in the Specification & illustrated by the
accompanying drawings.
2. Improved means & method for glazing greenhouses conservatories, railway
stations & the like the use of holdfasts some with & some without a heel in com-
bination with nails or screws driven into sash bars or rafters between two rows of
glass previously bedded in putty, the holdfast portion firmly securing the glass on
both sides of nail to the rafters or sash bars as before stated in the Specification &
illustrated in accompanying drawings.
3. The combination of holdfast, nail or screw & sash bar with anti-drip grooves
on bar substantially as before stated in Specification & illustrated in accompanying
drawings.
