IMPROVEMENTS IN BLINDS OR SCREENS FOR WINDOWS
Year: 1882

page_text: LETTERS PATENT to James Wetherilt, of 10 West Chapel Street Mayfair in
the County of Middlesex Builder and House Decorator. for an Invention of
"IMPROVEMENTS IN BLINDS OR SCREENS FOR WINDOWS."
PROVISIONAL SPECIFICATION left by the said James Wetherilt at the
Office of the Commissioners of Patents on the 6th March 1882.
JAMES WETHERILT of 10 West Chapel Street Mayfair in the County of
Middlesex Builder and House Decorator "IMPROVEMENTS IN BLINDS OR SCREENS
FOR WINDOWS."
The improvements in blinds or screens are particularly applicable to that class
of blinds or screens commonly called "dwarf' or such as only exclude or limit the
extent of view through or screen the lower portion of a window the upper
portion of the window being protected when required by roller or other description
of blind.
In carrying these improvements into effect I form the blind or screen by a
surrounding frame with bars rods rails or laths the upper and lower opposite sides
of this frame are provided with studs to pass into slotted openings. The lower
of these parts act as hinges for the lower edge of the blind to turn on and when the
blind or screen is closed to the window they also serve as part of the locking
means whilst the upper parts admit of the release of the studs and of that part
of the blind or scren so that it may be inclined and when inclined folding arms
with hooked parts towards their ends operate by these hooked parts taking on to
the studs before referred to at the upper part of the blind to hold the blind to the
desired inclination.
When the blind or screen is in an upright position close to the window the
folding arms serve to lock or fasten the blind in that position in the slotted openings.
By these means facility for maintaining privacy from observation is secured with
efficient ventilation with the blind or screen in its upright position against the
window especially during daylight. whilst increased ventilation is attained with
the blind inclined and its action as a screen is especially with artificial light within
the room much enhanced and I am further enabled to employ the surfaces of the
blinds or screens for the display of ornamental or other designs.

the said James Wetherilt in the Great Seal Patent Office on the 5th September
1882.
JAMES WETHERILT of 10 West Chapel Street Mayfair in the County of
Middlesex Builder and House Decorator. "IMPROVEMENTS IN BLINDS OR SCREENS
FOR WINDOWS."
The improvements in blinds or screens are particularly applicable to that class
of blinds or screens commonly called "dwarf" or such as only exclude or limit the
extent of view through or screen the lower portion of a window, the upper portion
of the window being protected when required by roller or other description of
blind.
In carrying these improvements into effect I form the blind or screen by a
surrounding frame with bars rods rails or laths the upper and lower opposite sides
of this frame are provided with studs to pass into slotted openings.
The lower of these parts act as hinges for the lower edge of the blind to turn on,
and when the blind or screen is closed to the window they also serve as part of
the locking means whilst the upper parts admit of the release of the studs and of
that part of the blind or screen so that it may be inclined and when inclined
folding arms with hooked parts towards their ends operate by these hooked parts
taking on to the studs before referred to at the upper part of the blind to hold the
blind to the desired inclination.
When the blind or screen is in an upright position close to the window the
folding arms serve to lock or fasten the blind in that position in the slotted
openings.
By these means facility for maintaining privacy from observation is secured
with efficient ventilation with the blind or screen in its upright position against
the window whilst increased ventilation is attained with the blind inclined
and its action as a screen is especially with artificial light within the room much
enhanced and I am further enabled to employ the surfaces of the blinds or screens
for the display of ornamental or other designs.
But that the invention may be the better understood I will by the aid of
the accompanying drawings proceed to describe means pursued by me in carrying
the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a front view of a window frame with my improvements applied
Figure 2 shows a sectional view Figure 3 an edge view of the same. Figures 4
and 5 show the parts in different positions and Figures 6, 7. 8. 9. 10. 11. 12. 13.
14. 15. 16. 17. 18. 19 20. 21. 22 and 23 shew parts separately.
This
In each of the figures the same letters indicate corresponding parts wherever
they occur. a. a. indicates the frame of the window. b the blind or screen.
blind or screen as shewn is formed by a surrounding frame 6' and a series of bars
rods rails or laths 6 or other suitable surfaces. The upper and lower opposite
sides of this frame 6 are provided with studs c. c. and c¹. c. adapted to pass into
sockets or holders d. d. and d¹. d. respectively each being provided with slotted
openings d². d. and affixed to the surrounding frame a. The lower of these parts,
that is, the studs c¹. c. and slotted sockets or holders d'. d. act as hinges for the
lower edge of the blind b to turn on as indicated by the Figure 5 but when the
blind or screen is closed to the window all these studs c. c. and c¹. c'. when passed

page_text: means. When the blind or screen is desired to be inclined as indicated by
Figure 5 it may be held at the inclination desired by means of the arms e. e. with
the hooked ends e¹. e'. hooking on to the grooved studs c. c. for the inclination for
the time desired and when in such an inclined position the blind or screen
especially by gas-light or other interior lighting by the angular direction of the
parts be causing each rail or part to overlap or interfere with the line of sight in
a horizontal direction prevents undesired observation of the interior of the room or
other place where the blind or screen is applied without in anyway impeding the
flow of air for ventilation.
It will be obvious that the form and character of the holding parts and other of
the details will be capable of very considerable variation.
When the blind or screen is in an upright position close to the window the
arms e. e, serve to lock or fasten the blind or screen in that position by resting at
their lower ends e². e. on the lower studs to prevent the blind or screen from
being raised to be released.
Of the detail views to a larger scale Figure 6 by side view shows a holder or
socket suitable for the upper left hand side of the window frame. Figures 7 and 8
by side and front view that for the right hand side Figures 12. 13 and 14 by side
sectional and edge views the left hand lower socket and Figure 15 by side view
the right hand lower socket Figures 9 and 10 shew by side and front views and
Figure 11 by side view the studs c. c. suitable for engaging with the parts shewn
by Figures 6 and 7 respectively. Figures 16. 17 and 18 show by front and rear
edge views, and front view a stud and its supports for the left hand and Figures 19.
20 and 21 show by similar views the corresponding part for the right hand
lower edges of the blind suitable to engage with the parts shewn by Figures 12
and 15 respectively.
The fins or projections c². c². of these pieces are for the purpose of facilitating
correct working and adjustment of the parts c¹ and d. Figures 22 and 23 show
by side and edge views one of the arms e.
It will readily be understood that the surfaces of the parts 62 supported by the
frame b may afford considerable facility for the display of designs or representations
of a highly artistic or ornamental character.
Having thus described my invention and means which I adopt in carrying the
same into effect I would have it understood that I do not confine myself to the
precise details shown as these may be varied But what I do claim is the arranging
or combining parts forming blinds or screens for windows adapted to be operated
in manner substantially as described.
In witness whereof I the said James Wetherilt have hereunto set my hand
and seal this first day of September One thousand eight hundred and
night ton
