IMPROVEMENTS IN T DOG
Year: 1865

page_text: LETTERS PATENT to Charles Beard, of Bury St. Edmunds, in the County
of Suffolk, Justice of the Peace, for the Invention of "IMPROVEMENTS IN
T
DOG"
PROVISIONAL SPECIFICATION left by the said Charles Beard at the
Office of the Commissioners of Patents, with his Petition, on the 6th
February 1865.
I, CHARLES BEARD, of Bury St. Edmunds, in the County of Suffolk, Justice
of the Peace, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR VENTILATING HORTICULTURAL AND OTHER BUILDINGS," to
be as follows:-
This Invention has for its object improvements in apparatus for ventilating
horticultural and other buildings. For these purposes, in constructing glazed
ventilating apparatus for the tops of greenhouses and other buildings, I employ
along the ridge or upper angle of the glazed roof glazed frames, which are
hinged at their upper ends or parts to the ridge or upper part of the roof. To
the glazed frames constituting the ventilating apparatus I apply stretchers or
connecting rods, one or more to each; these are pin-jointed at one end to the
lower parts of the glazed frames of the ventilating apparatus, and at their
other ends to a bar running from end to end of the ventilating apparatus.

page_text: This bar is connected to rings or slides which slide on uprights or supports
fixed at intervals along the greenhouse or building under the ridge or angle of
the roof. These rings or slides are connected by rods or otherwise with other
rings or slides on the same upright, and these are weighted to counterbalance
the frames of the ventilating apparatus. Over the ridge or upper part of the
roof I apply a cap in order that the rain may be thrown off.
It will be understood that the inclined glazed frames of the roof of the
house do not go up to the ridge at the top of the house, but leave an open
space, which space is closed by the ventilating glazed frames when they are
shut, and such ventilating frames may be more or less opened by sliding the
rings or slides on the uprights.
In order to open and close several of the upright windows or glazed frames
of a horticultural or other building at the same time the windows are caused
to turn on pivots or hinges, and connecting rods or stretchers are pin-jointed to
them and to a bar which is capable of being slid or moved so as to cause all
the stretchers or connecting rods simultaneously to act on their respective
windows. To facilitate the movement of the bar it is counterbalanced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Beard in the Great Seal Patent Office on the 29th
July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BEARD, of Bury St. Edmunds, in the County of Suffolk, Justice of the Peace,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Charles Beard, Her special licence that I, the said Charles
Beard, my executors, administrators, and assigns, or such others as I; the
said Charles Beard, my executors, administrators, and assigns, should at any
tine 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 Invention for "IMPROVEMENTS IN
APPARATUS FOR VENTILATING HORTICULTURAL AND OTHER BUILDINGS," upon the
condition (amongst others) that I, the said Charles Beard, my executors or

page_text: administrators, by an instrument in writing under my, 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 Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Charles Beard, do hereby declare the
nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:
This Invention has for its object improvements in apparatus for ventilating
horticultural and other buildings. For these purposes in constructing glazed
ventilating apparatus for the tops of greenhouses and other buildings, I employ
along the ridge or upper angle of the glazed roof glazed frames, which are
hinged at their upper ends or parts to the ridge or upper part of the roof. To
the glazed frames constituting the ventilating apparatus I apply stretchers or
connecting rods, one or more to each; these are pin-jointed at one end to the
lower parts of the glazed frames of the ventilating apparatus, and at their
other ends to a bar running from end to end of the ventilating apparatus.
This bar is connected to rings or slides, which slide on uprights or supports
fixed at intervals along the greenhouse or building under the ridge or angle of
the roof. These rings or slides are connected by rods or otherwise with other
rings or slides on the same upright, and these are weighted to counterbalance
the frames of the ventilating apparatus. Over the ridge or upper part of the
roof I apply a cap in order that the rain may be thrown off.

It will be understood that inclined glazed frames of the roof of the house
do not go up to the ridge at the top of the house, but leave an open space,
which space is closed by the ventilating glazed frames when they are shut,
and such ventilating-frames may be more or less opened by sliding the rings
or slides on the uprights.
In order to open and close several of the upright windows or glazed frames
of a horticultural or other building at the same time, the windows are caused
to turn on pivots or hinges, and connecting rods or stretchers are pin-jointed to
them and to a bar which is capable of being slid or moved so as to cause all
the stretchers or connecting rods simultaneously to act on their respective
windows. To facilitate the movement of the bar it is counterbalanced.
And in order that my Invention may be more fully understood, and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.

page_text: Figure 1 is a vertical section, and Figure 2 a plan, of part of a greenhouse
of the form known as a "lean-to."
a, a, are the glazed frames of the ventilating apparatus, which are hung at
a' by binges or otherwise to the ridge or upper part of the roof; to the lower
part of these frames a are pin-jointed stretchers or rods 6, which at their other
ends are pin-jointed to a horizontal rod or hollow tube c running from end to end
of the building; this rod or tube c may be connected to rings or slides which
slide on uprights or horizontal supports fixed at intervals along the greenhouse
or building under the ridge or angle of the roof; these rings or slides being
connected by rods or otherwise with other rings or slides on the same upright,
which are weighted to counterbalance the frames of the ventilating apparatus,
and such ventilating frames may be more or less opened by sliding the rings
or slides on the uprights. The mode, however, in which I prefer to act upon
the rod or bar c or hollow tube is that shown in the Drawing. On one end of
the rod or bar c is formed a screw-thread c', which takes into a corresponding
thread formed in the female screw d. On the screw d is formed or fixed a
bevilled pinion d', which is taken into by and receives motion from a bevilled
pinion e on the upright shaft or axis ; to the lower end of the shaft or axis e
is fixed a handle e, by turning which in one or the other direction the rod or
bar c is moved endwise in its supports, and consequently the glazed frames of
the ventilating apparatus are all simultaneously opened or closed. Instead,
however, of employing the mode shown in the Drawings for moving the rod
or bar or hollow tube c endwise in its bearings, a lever may be connected to
one end thereof, the lower end of which lever may take into notches in a bar
or plate fixed to the wall or other part of the building, in order that the
glazed frames a may be held in any desired position.
"
Figures 3 and 4 are similar views to those shown at Figures 1 and 2 of a
span-roof" conservatory or building having a double set of glazed frames or
ventilating apparatus a applied thereto; these frames a are operated in a
similar manner to that shown at Figures 1 and 2 by the rod or bar or hollow
tube c. Similar parts are marked with like letters of reference to those employed
in Figures 1 and 2.
Figure 5 is a vertical section of a dome-shaped conservatory or building,
having the glazed frames a hung on binges or pivots at a¹. These frames a are
pin-jointed at their lower ends to stretchers or rods b, which at their other ends
are piu-jointed to the upper end of a tube c, which is capable of being slid or
moved up or down on the upright rod or bar or hollow tube d, and of being

page_text: fixed in any desired position by a pin passing through a hole in the lower part
of the tube c, and into one or other of the holes in the upright rod, hollow
tube, or bar d. Glazed frames of a span roof or other form of conservatory or
building may be operated in a similar manner to that shown at Figure 5. In
this manner may any desired number of glazed frames or ventilating apparatus
be operated upon.
Having thus described the nature of my said Invention, and the mode I
prefer of carrying the same into effect, I would have it understood that I do
not confine myself to the precise details herein shewn and described; but
what I do claim is the combined arrangements of mechanism for opening
and closing the ventilating apparatus of horticultural and other buildings,
substantially as herein shown and described.
In witness whereof, I, the said Charles Beard, have hereunto set my
hand and seal, this Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and sixty-five.
CHARLES BEARD. (L.s.)
