An Improved Sun-blind for Shops and Show Windows.
I, WILLIAM RUTHERFORD COONEY, Merchant, Enniskillen, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved sunblind for shops and show windows.
The object of the invention is to so construct and arrange the blind that whilst
the goods in the window are protected from injury by the sun a portion of the
sunlight is admitted into the interior of the shop so as to light it up.
In carrying out tne invention I use a double blind arrangement one blind being
the usual outside one supported on stays and the other being an inside one
arranged above the goods in the shop window. A portion of the shop window
above the blinds is left open so as to admit light when the blinds are drawn.
The outer blind is wound on a spring roller and so also is the inner blind.
Both blinds are or may be connected to pulleys or to a cross shaft having pulleys
at each end with counterweights.
The whole arrangement is such that when the outer blind is drawn out the inner
blind is also simultaneously drawn out from its roller right over the goods in the
window thereby forming a sort of screen for them. When the stays supporting
the outside blind are bent upwards the action of the counterweight pulleys draws
them close up against the window. The sunlight is admitted into the shop above
the blinds when they are drawn.
If desired a permanent cover may be fitted at the inside of the window and be
constructed with lattices and such like as to admit light through the top.

I, WILLIAM RUTHERFORD COONEY, Merchant, Enniskillen, do hereby declare the
nature of this 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 relates to an improved sunblind for shops and show windows.
The object of the invention is to so construct and arrange the blind that whilst

page_text: the goods in the window are protected from injury by the sun a portion of the
sunlight is admitted into the interior of the shop so as to light it up.
In carrying out the invention I use a double blind arrangement one blind being
the usual outside one supported on stays and the other being an inside one
arranged above the goods in the shop window. A portion of the shop window
above the blinds is left open so as to admit light when the blinds are drawn.
The outer blind is wound on a spring roller and so also is the inner blind.
Both blinds are or may be connected to pulleys or half pulleys, or equivalent,
or to a cross shaft having pulleys at each end with counterweights.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front view and Fig. 2 a vertical section showing the arrangement.
Referring to the drawings:-
a is the outside blind supported by the stays b whilst c is the inside blind
arranged above the goods in the shop window d. e is a space at the top of the
shop window which is left open, above the blinds, so as to admit light to the shop
when the blinds are drawn. f is the spring roller upon which the blind a is
wound. g is a similar roller upon which the inner blind is wound. j,j, are two
half pulleys or segmental wheels arranged one at each side of the window and
provided with peripheral grooves j, ². The bottom of each pulley is made with
an extension in which the ends of the blind roller f are carried. h, h, are chains
or cords which extend from the points of each stay up to the points r of each
half-pulley then round the grooves of the half-pulleys and down under the
guide pulleyss to the ends of the carrier t of the back blind c.
,, are chains
or cords which extend from the stays b, at the points 1, through the tubes or
passages m in the window frame, round the pulleys of the weights, over the
pulleyss to the grooves of the half-pulleys jround which they pass and then
down over the guide pulleys i to the weights o.
The points on the blind stays or rods are arranged, as shown, so as to
practically constitute fulcrums about which the stays can turn when the blind
carrier pis being pushed up. When the stays bare so turned the slide plates u
to which they are jointed move down in the slots u, u, made in the window
frame.
The whole arrangement and construction is such that when the carrier pis
pushed up so as to close the blinds a, e, the latter will, by virtue of the internal
springs of the rollers f, g, wind up automatically. The half pulleys simul-
taneously turn upon their pivots until the blind roller f, which is carried by the
half-pulleys, bears against the stop w at the top of the window. The half pulleys
revolve anti-clockwise on their centres v. During this operation the weights n
and o fall down and the plates u of the stays b slide down to the bottom of the
slots u¹.
The chains are secured to the half pulleys at r. The chains h are free to slide
in the inner grooves of the half pulleys j.
If desired a permanent cover may be fitted at the inside of the window behind
the part e and be constructed with lattices and such like so as to admit light
through the top.
When the blinda is not in use as a sun shade and is rolled up the movement
of the half pulleys j brings it up against the stop we so that the front of the shop
window is left clear.
Circular, instead of semicircular, pulleys j may be used.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I consider novel and desire to claim is:-
1. A blind arrangement for shop windows consisting of an outer blind. and an
inner blind which are capable of being opened out and closed up simultaneously,
substantially as set forth.

page_text: 2. The arrangement for raising and lowering the roller (f) of the outer blind
consisting of half pulleys or their equivalent provided with counter weights,
substantially as set forth.
3. A double blind for shop windows constructed, arranged and operating
substantially as herein before described with reference to the drawings annexed.
