AN IMPROVED MODE OF GLAZING HORTICULTURAL BUILDINGS, RAILWAY STATIONS, AND SIMILAR STRuctures.”
Year: 1871

page_text: LETTERS PATENT to John Edgcumbe Rendle and Ambrose Burrows,
both of No. 18, Castle Street, East, Oxford Street, in the County of
Middlesex, for the Invention of "AN IMPROVED MODE OF GLAZING
HORTICULTURAL BUILDINGS, RAILWAY STATIONS, AND SIMILAR STRuctures.”
PROVISIONAL SPECIFICATION left by the said John Edgcumbe Rendle
and Ambrose Burrows at the Office of the Commissioners of
Patents, with their Petition, on the 7th November 1871.
We, JOHN EDGCUMBE RENDLE and AMBROSE BURROWS, both of
No. 18, Castle Street East, Oxford Street, in the County of Middlesex,
do hereby declare the nature of the said Invention for "AN IMPROVED
MODE OF GLAZING HORTICULTURAl Buildings, RaILWAY STATIONS, AND SIMILAR
STRUCTURES," to be as follows :-
-
This Invention consists in a new mode of fixing glass in buildings
generally, but is more particularly adapted for horticultural buildings,
greenhouses, roofs of railway stations, and other similar structures, by
which Invention putty, felt, and such like materials ordinarily used are

page_text: entirely dispensed with, and the glazing and repairing effected with
much greater rapidity and economy than at present, as well as tho-
roughly excluding all wet, and with the least possibility of getting out
of repair.
In this Invention the sash bars are construct in various kinds of 5
metal and other suitable material, and in the form shown on accom-
panying Drawings, A having a groove or gutter B, B, on either side of
same, and on which is laid the glass C. No putty or such like adhesive
being used should wet penetrate the sides of the glass it is received into
and carried off by the small gutters or grooves B, B, which run down 1
the whole length of the bar and sash, see Fig. 3. If found necessary,
the sash bars could contain a wood or other core, so as to strengthen
them in very long lengths.
To effectually exclude draughts when necessary, the lips or edges of
the gutters are turned flat against the under face of the glass, see 1
Figs. 2 and 4.
To prevent the sheets of glass from slipping down a metal cramp D
with a notch on the sides is placed on the bar, as shewn on Figs. 3, 4, 5,
and 6, with a moveable screw at the side to securely fix the same on the
bar, the bottom edge of the sheet of glass being caught by the notch on 2
the cramp, see D, Fig. 3.
A lengthened form of cramp is shown at Fig. 7 to cover the entire
length of the bar if necessary, and is made with a series of notches.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
EDGCUMBE RENDLE and AMBROSE. Burrows, both of No. 18, Castle
Street, East, Oxford Street, in the County of Middlesex, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Edgcumbe Rendle and
Ambrose Burrows, Her special licence, that we, the said John Edg-
cumbe Rendle and. Ambrose Burrows, our executors, administrators, and
assigns, or such others as we, the said John Edgcumbe Rendle and
Ambrose Burrows, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven--
tion for "AN IMPROVED MODE OF GLAZING HORTICULTURAL BUILDINGS, RAILWAY
STATIONS, AND SIMILAR STRUCTURES," upon the condition (amongst others)
that we, the said John Edgcumbe Rendle and Ambrose Burrows, our
executors or administrators, by an instrument in writing under our,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Scal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Edgcumb Rendle, for myself
and on behalf of the said Ambrose Burrows, do hereby declare the nature
of our said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement:
This Invention consists in a new mode of fixing glass in buildings
gencrally, but is more particularly adapted for horticultural buildings,
greenhouses, roofs of railway stations, and other similar structures, by
which Invention putty, felt, and such like materials ordinarily used

page_text: are entirely dispensed with, and the glazing and repairing effected
with much greater rapidity and economy than at present, as well as
thoroughly excluding all wet, and with the least possibility of getting
out of repair.
In this Invention the sash bars are constructed in various kinds of
metal and other suitable material, and in the form shewn on accom-
panying Drawings, A having a groove or gutter B, B, on either side of
same, and on which is laid the glass C. No putty or such like adhesive
being used should wet penetrate the sides of the glass it is received into
and carried off by the small gutters or grooves B, B, which run down
the whole length of the bar and sash, see Fig. 3.
If found necessary,
the sash bars could contain a wood or other core, so as to strengthen
them in very long lengths.
To effectually exclude draughts when necessary the lips or edges of
the gutters are turned flat against the under face of the glass, see
Figs. 2 and 4.
To prevent the sheets of glass from slipping down a metal cramp D
with a notch on the sides is placed on the bar, as shewn on Figs. 3, 4, 5,
and 6, with a moveable screw at the sido to securely fix the same on the
bar, the bottom edge of the sheet of glass being caught by the not on
the cramp, see D, Fig. 3.
A lengthened form of cramp is shewn at Fig. 7 to cover the entire
length of the bar if necessary, and is made with a scries of notchics.
Another mode of fixing can be adopted by means of a capping cut in
lengths corresponding with the glass, and which is fixed to tho bar by
screws; Fig. 8 is a section, shewing this method of fixing; Fig. 9 shows
plan of same.

lengths of the glass; is the glass; h, h, grooves to carry
off drip; i, screw to fasten capping to bar.

9 shews plan of same.
Having thus described the nature of our said Invention, and the mode
of carrying the same into effect, what we claim and desire to be secured
to us by Letters Patent is, the said Invention for an improved mode of
glazing horticultural buildings, railway stations, and similar structures,
substantially as herein described, and as shewn on the accompanying
Drawings, or any mere modification thereof.
In witness whereof, I, the said John Edgcumbe Rendle, for myself
.and on behalf of the said Ambrose Burrows, have hercunto set
my hand and scal, this Fourth day of May, in the year of our
Lord One thousand eight hundred and seventy-two.
JOHN EDGCUMBE RENDLE. (L.S.)
