PROVISIONAL SPECIFICATION.
Improvements in Sun Blinds for Shop Windows.
I, ISAAC KIRKBRIDE of 28, Hope Terrace, Walton Street, Colue, in the County of
Lancaster, Joiner and Cabinet-Maker, do hereby declare the nature of this invention
to be as follows :-
The object of this invention is to render sun blinds self adjusting.
For this purpose, I employ the ordinary sun blind roller and place it as usual
within the window cornice; and near one or both ends of the said roller, I employ a
coil spring, one end of which is connected to a fixed point and the other to the
roller, so that, when the blind is lowered to present the shade, the spring will be
wound up.
The reclining rods are attached to the bar at the extremity of the blind as usual,
with their opposite ends capable of being raised upon the vertical fixed bar, to
throw the reclining rods into a horizontal position out of the way of persons
passing by.
The raising and lowering of the reclining rods is effected automatically instead of
by hand; And for this purpose, I connect the inner ends of the reclining rods to the
blind roller by means of a cord, chain, or metal band, so that when the blind is drawn
outwards, the cord or the like will be wound upon the roller, raising the reclining
rods by their inner ends to a horizontal position. When it is desired to remove the
sun shade, it is simply necessary to lower the reclining rods when the blind will be
wound upon the roller by the reaction or opening of the spring.

COMPLETE SPECIFICATION.
Improvements in Sun Blinds for Shop Windows.
I, ISAAC KIRKBRIDE of 28 Hope Terrace, Walton Street, Colne, in the County of
Lancaster, Joiner and Cabinet Maker, 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 of improvements is designed to render sun-blinds self adjusting;
and to balance by means of a spring the weight of the reclining rods and the canvass
when extended.
For this purpose, I employ the ordinary sun-blind roller and place it as usual
within the window cornice, and near one or both ends of the said roller I place a
coil spring, one end of which is attached to a fixed stud within the coil, and the
other to the roller, so that when the blind is lowered to present the shade or blind,
the spring will be wound up.
Reclining rods are attached to the bar at the extremity of the blind as usual,
with their opposite ends capable of being raised upon vertical bars or uprights to
throw the reclining rods into a horizontal position, out of the way of persons
passing by.
For this purpose, I connect the inner ends of the reclining rods to the blind
roller, by cords, chains or flexible metal bands, so that when the blind is drawn
outwards the cords or the like will be wound upon the roller, raising the reclining
rods by their inner ends to a horizontal position,

page_text: When it is desired to remove the sun-shade or blind, a pull-cord is drawn
to release a catch, when the blind will be wound upon the roller by the reaction of
the spring.

In the accompanying drawings Fig. 1 is an end elevation, Fig. 2 a front view, and
Fig. 3. an elevation reverse to Fig. 1, of a window frame with a sun shade or blind
constructed in accordance with my invention. Fig. 4 is an enlarged view in
section of a casing and barrel, within which the spring for rewinding the blind is
coiled.
A represents the window-framing, B the roller on which the blind is wound
D, D the reclining rods, attached to the ends of the bar C, to which the end of the
blind is fixed. The parts, enumerated are of the ordinary construction. To one end
of the blind B is secured barrel E, capable of turning or revolving on stud F, secured
to the end of casing G and projecting inwards. Within the barrel is coil-spring H,
one end of which is fixed to stud F, and the other to the barrel E, similar to the
main spring of a clock.
When therefore the blind is drawn down as represented on the drawings the coils
of the spring H are drawn closer to each other. During this operation of lowering
the blind the flexible bands II, attached to the slide-pieces J are wound upon the
necks of the roller B, raising the inner ends of the reclining rods D and the slide-
pieces J upon the vertical bars K, to the position seen in Figs. 1, 2 and 3. The
catch L prevents the reaction of the spring by engaging with the teeth. of ratchet
wheel Ofixed to the arbor of the blind-roller B. When it is desired to raise the
blind, the catch L is removed from the ratchet wheel O by the pull cord P, allowing
the spring H to reassert itself and wind the blind upon the roller, and at the same
time lower the inner ends of the reclining rods, by unwinding the flexible metal
bands I from the roller B.
It will be obvious that where the window is sufficiently elevated, the flexible
bands I may be dispensed with; the inner ends of the reclining rods may then be
attached to a stationary joint when such reclining rods are out of the way of
passers by.
In some cases a weight and cord may be beneficially substituted for the spring H
to rewind the blind upon the roller B.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In sun shades or window blinds, the combination of roller B, barrel E, coil
spring H reclining rods D and bands I, operating substantially as described.
2. In sun shades or window blinds, roller B, reclining rods D, catch L, and ratchet
wheel O, substantially as described.
