NOW KNOW YE, that I, the said William Steads, do hereby declare.
the nature of the said Invention, and in what manner the same is to.
be performed, to be particularly described and ascertained in and by
the following statement thereof (that is to say):
This Invention consists of so arranging the apparatus of a roller,
blind, or other article that the blind or article shall be in equilibrium
with the weighted cord on the pulley of the roller. By which combin-
ation of parts all racks and springs are dispensed with, and the blind,.
map, or other article is wound on to or unwound from its roller by
simply raising or lowering the end of the weighted cord.

page_text: And in order that my Invention may be most fully understood I will
proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1: A, roller; B, section of pulley shewing the centre or axle
b, to which the line A, C, is fixed for drawing up the blind, map,
print, &c.; E, section of boxed bracket to prevent the line getting over
the pulley; F, window casing. Figure 2, section of the pulley shewing
the centre b, and the line A, fixed thereto. Figure 3, boxed bracket
shewing the line coiled round the centre of pulley, and passing through
a hole at f. G, collet or small pulley to keep the blind, map, print,
or other article on an equilibrium with the weight of the balance, tassel,
or bag at B, fixed to the line A, suspended from the pulley, which is
fixed to the end of roller. Figures 4, and 5, perspective view of pulley
and boxed bracket. Figure 6, shows the blind when drawn up. The
line from B, to C, is equal to the length of the blind, map, print, &c.
By pulling down the blind with the line E, will raise and coil the line
A, C, round the pulley at C. Then by pulling down the line A, C, it
will raise the blind as before. At B, is a balance, tassel, or otherwise,
of equal weight to that of the blind, map, print, &c., including the slat
at f. The line from B, to C, being of the same length as the blind,
map, print, or other article, will prevent the blind slat f, from turning
over the roller a.
In witness whereof, I, the said William Steads, have hereunto set
my hand and seal, this Thirteenth day of July, in the year of
our Lord One thousand eight hundred and fifty-three.
WILLIAM STEADS. (L.S.)
