Year: 1869

page_text: LETTERS PATENT to William Henry Dupré, of Jersey, for the
Invention of "IMPROVED APPARATUS FOR GIVING LIGHT AND VENTILATION
TO ROOMS, HOUSES, OR OTHER BUILDINGS."
PROVISIONAL SPECIFICATION left by the said William Henry Dupré
at the Office of the Commissioners of Patents, with his Petition,
on the 21st May 1869.
1, WILLIAM HENRY DUPRE, of Jersey, do hereby declare the nature
of the said Invention for "IMPROVED APPARATUS FOR GIVING LIGHT AND
VENTILATION TO ROOMS, HOUSES, OR OTHER BUILDINGS," to be as follows (that is
to say):-
My Invention has reference to an improved mechanical construction
and arrangement of apparatus for giving light and ventilation to apart-
ments or otherwise, as above referred to, by which the self-acting and
other parts thereof are more effectually combined and maintained in
Price Bd.1

page_text: working order with less wear and tear than at present, and consists of a
metallic case or shaft of rectangular or other suitable form (secured to
the ventilating aperture by any convenient method), upon the upper
edge of which a glazed valve or cover is fitted, opening outwards from
a single hinge, in such manner that rain or wet is prevented from
descending the aperture "either when open or closed) by inserting the
glass in a rabbet or groove within the said cover, so as to overlap the
inner lip or edge of the tubular case or shaft upon which wire gauze is
stretched.
And, secondly, in substituting (in lieu of the said glazed valve) a top
or cap revolving upon the said ventilating case supported upon a curved
vertical spindle of corresponding shape to the top or case aforesaid. by
means of which any accumulation of dirt or otherwise may be scraped off
or removed by the revolving action of the cap, thereby facilitating the
passage of air through the same, in connection with which six or more
external deflecting curvilinear blades, having a corresponding number
of internal air conducting chambers with conical cap rims are also
employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Dupré in the Great Seal Patent Office on
the 19th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY DUPRE, of Jersey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of May, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Eler heirs and successors,
give and grant unto me, the said William Henry Dupré, Her special
licence, that, the said William Henry Dupré, my executors, admi-
nistrators, and assigns, or such others as 1. the said William Henry
Dupré, my 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 expressod, should and lawfully might make,
use, exercise, and vond, within the United Kingdom of Great Britain

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVED APPARATUS FOR GIVING LIGHT AND VENTILATION TO ROOMS, HOUSES,
OR OTHER BUILDINGS," upen the condition (amongst others) that I, the
said William Henry Dupré, my executors or 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 Lettors
Patent.
NOW KNOW YE, that I, the said William Henry Dupré, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (and the Drawings therein referred to (that
is to say):-
My Invention has reference to the improved mechanical construction
and mode of employing apparatus for giving light and ventilation to
apartments, rooms, houses, or other buildings, by which arrangement the
said parts thereof are more effectually maintained in working order with
less wear and tear and complexity of the parts than at present, and
consists, firstly, in simplifying the form and construction of roof lights,
having for its object a more effectual method of inserting the glass
within the valve frame through the medium of a rabbet or slider fitted
with a hinged beading, in which the glass is enclosed and protected on
all sides in conjunction with square or round corners forming the base
or bottom plate to the roof lights aforesaid.
Secondly. In the employment and mode of opening and closing pane
ventilators by means of sash weights and cords applied thereto, by which
it is opened and shut as required, and fitted with wire gauze at the top
of same for the exclusion of dust, insects, or otherwise.
Thirdly. In improved wind guards for accelerating the passage of
smoke, and giving greater freedom of ventilation by means of internal
chambers or conducting passages combined with external downward
deflecting curvilinear ribs or blades for directing the wind to within
seven or eight inches, more or less. from the top of the body barrel. also
provided with one or more taper rims attached to the upper portion of
the said wind guard.

page_text: Fourthly. The mode of attaching the deflecting curvilinear outor
blades or ribs to a taper rim leading into the upper hoop of the said wind
guard, provided with top tapered rims, as in the former case.
:
Fifthly. In the peculiar form and construction of spindle (supporting
the usual lobster back" or sugar loaf hoods or caps) for scraping
off or preventing any accumulation of soot or otherwise within the said
caps by the revolving action of the saune, and offering less resistance to
the sweeping brush.
And in order that. my said Invention may be more fully understood
and readily carried into effect, I now proceed to describe the same by aid
of the accompanying Drawings, reference being had to the letters and
figures thereon marked (that is to say):-
Fig. represents a perspective view of my improved roof ventilating
light (partly open); Fig. 2, a side view thereof; Fig. 3, enlarged detail
view of the hinged beading by which the glass is inserted and secured
within the slide; Fig. 4, a side view thereof; Fig. 5, a corresponding
view of the pane, window, or panel ventilator constructed in accordance
with my Invention; Fig. 6, a side view thereof: Fig. 7. a top or plan
view, showing the open wire gauze top, and Fig. S, an enlarged sectional
view of the sash weights and tube; Fig. 9, a side elevation of my
improved wind guard or cowl; Fig. 10, a vertical section thereof,
showing the internal chambers and outer curvilinear blades for directing

thereof may be otherwise varied as in practice may be found necessary.
Having now fully described and ascertained the nature of this my
said Invention, and the manner in which the saine is to be performed
and carried into effect, I would have it clearly understood that I do not
intend to confine myself to the precise details heroin-before set forth and
described, as the same may be otherwise varied without departing from
the general principle of this my said Invention; nor do I claim as new
and of my said Invention the exclusive use of the several parts, com-
binations, and processes except when the same are employed in and for
the purposes of my said Invention, which I hereby declare to consist,―
Firstly. In the mode of securing the glass within the rabbet of roof
lights, , as above described, through the medium of the hinged beading or
covering and stud bolts or other modifications thereof, in which the glass
can be inserted or withdrawn through the medium of a hinged
beading.
Secondly. The employment and mode of arranging sash weights in
pane ventilators, as above referred to, in connection with open wire
gauze top to same.
Thirdly. The exclusive right of employing inward chambers for
guiding or directing the wind deflected by the outer spiral blades to
within seven or eight inches, more or less, of the top of the body barrel,
provided with conical rims, as herein-before described at Figs. 9, 10, 11,
12, 13, 14, 15, and 16.
Fourthly, and lastly. The construction and mode of employing the
curved spindle in wind guards or cowls, as shown at Q, Q, Figs. 17, 18,
19, 20, 21, and 22, with any or all of their various modifications that

page_text: may oc found necessary, in the manner and for the purposes herein.
before set forth and described.
In witness whereof, I, the said William Henry Dupré, have
hereunto set my hand and seal, this Twenty-first day of October,
in the year of our Lord One thousand eight hundred and sixty-
nine.
