Year: 1877

page_text: LETTERS PATENT to Arthur John Baker, of Great Saint Helen's, Bishopsgate,
in the City of London, for the Invention of "IMPROVEMENTS IN WINDOW
FITTINGS"
Sealed the 13th October 1877, and dated the 19th April 1877.
PROVISIONAL SPECIFICATION left by the said Arthur John Baker at the
Office of the Commissioners of Patents on the 19th April 1877.
ARTHUR JOHN BAKER, of Great Saint Helen's, Bishopsgate, in the City of London.
"IMPROVEMENTS IN WINDOW FITTINGS."
My Invention relates to improvements in what are known as swing sashes,
whereby increased facility is afforded for opening the same to any angle for the
purposes of ventilation or cleaning, whilst at the same time effectually excluding
wind and rain, and it consists in placing the bead or rebate with the hinge or
centre on which the sash is mounted on the inner side of the sash and frame, and
in dispensing with the ordinary beads and stops so as to leave the window opening
free and unobstructed for the motion of the sash to any angle to which it may be
required to place it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Arthur John Baker in the Great Seal Patent Office on the 17th
October 1877.
ARTHUR JOHN BAKER, of Great Saint Helen's, Bishopsgate, in the City of London.
"IMPROVEMENTS IN WINDOW FITTINGS."
My said Invention relates to improvements in what are known as swing sashes,
and it has for its object providing increased facilities for reversing the sashes so
that the outside may be easily turned inside for the purposes of glazing or cleaning,
also enabling the sashes to be so adjusted and secured as to regulate the currents
of air both in volume and direction, and thus most efficiently to ventilate any
ID

page_text: apartment in which they may be placed, whilst retaining at the same time a pro-
tecting surface against storms and rain, and when closed an air and water-tight
joint secured by double rebates.
These objects are attained by dispensing with sunk rebates and substituting
therefor beads or fillets, placed on the inner side of the sash and window frame, the
sash being mounted on strap hinges carried on the bead or fillet on the frame and
attached to the bead or fillet on the sash.
The two Figures on the accompanying Drawing represent a mode of carrying
out my said Invention as applied to a window with two swing sashes; Figure 1
being a perspective view, and Figure 2 a vertical section of the same.
A is the window frame, and B, B¹, are the sashes. The frame A is provided
with beads or fillets a, a, on its inner side, covering the lower halves of the margins
of the sashes B, B', in the closed position of the latter, and the sashes are also pro-
vided with beads or fillets b, b', on the inner side of their upper halves, and also
by preference with weather moulds 62, 63. The sashes are mounted on hinges c, c¹,
carried on the beads or fillets a, a¹, and attached to the beads or fillets b, b',
respectively.
By means of this Invention the window opening is left free and unobstructed
for the motion of the sash, which may be placed at any angle or even reversed, that
is to say, turned outside, inside, when required. In my Drawing the sash B is
shewn in full lines as partially open, and in dotted lines in its reversed position,
and the sash B' is represented as closed.
By the use of the beads or fillets in substitution for rebates cut out of the solid,
considerable economy in labor and material is effected.
The sashes are by preference fastened by thumbscrews or latches, and regulated
by stays or by cords secured to cleats.
The sashes are not liable to get out of order, are simple in construction, and may
be made either plain or moulded to suit the architectural appearance of the buildings
in which they may be placed. They are specially adapted for hospitals, schools,
dwelling houses, and all other buildings requiring a well regulated and efficient
ventilation.
Having now described and particularly ascertained the nature of my said Inven-
tion and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the peculiar construction and arrangement of swing sashes and
window frames, substantially as herein-before described and illustrated by the
accompanying Drawings.
In witness whereof, I, the said Arthur John Baker, have to this my Speci-
fication, set my hand and seal, the Twelfth day of October, One thousand
eight hundred and seventy-seven.
ARTHUR JOHN BAKEK. (LS.)
