IMPROVE.
My improvement relates to that class of curtain rollers to which cords, levers,
ratchet wheels, and pauls, are employed for winding and unwinding the curtain
from the roller.
The principle object of my improvement is the manner of constructing, applying,
and arranging the lever, acted on by the cord for winding and unwinding the
curtain on and from the roller for, first, causing the power to be applied more direct
through the medium of the lever to the roller.
Second. To prevent the lever from being drawn to one side or out of line
when being acted on by the cord for winding and unwinding the curtain from the
roller,
Third. Constructing the lever and paul, and providing the paul with suitable
form and weight, and arranging it with the ratchet wheel and roller in such a
manner that the brackets in which the roller revolves may be attached to the top
or side of the window frame at any point within the quarter of a circle, more or
less, without interfering with or preventing the lever and paul from properly acting
on the ratchet wheel in winding or unwinding the curtain from the roller.
Fourth. Providing one end of the roller with a frictional device in combination
with my improved lever, so that the curtain may be drawn down by hand
independent of the action of the lever, paul, and ratchet wheel.
The roller is usually made of wood of suitable size and length, and provided with
axis of metal to each end for working in suitable bearings or brackets. These
brackets are constructed so that they may be placed in a vertical or horizontal
position for the roller to work in without interfering with the proper working of
the same. One end of the roller is provided with a spool, usually made of metal, for
receiving a cord for revolving the roller for winding and unwinding the curtain
therefrom, and also a ratchet wheel for holding the curtain in any desired position
by a paul attached to the cord lever. When it is desired to wind or unwind the
curtain from the roller, the lever is drawn down by the cord and releases the paul

page_text: from the ratchet wheel and thereby leaves the roller free to revolve. The cord
lever is usually attached to one of the roller brackets on its inside; the end of the
lever is provided with an eye hole for the winding cord to pass through. The lever
is so shaped that the end of it comes about opposite the longitudinal centre of the
cord spool on the roller, so that when it is acted on by the cord it prevents the
lever from being drawn to one side and catching, making no odds what position
the roller brackets are placed in.
The frictional device attached to the end of the roller for permitting the curtain
to be drawn down by hand independent of the cord, is composed of a loose axis in one
end of the roller, and provided with a spring in any convenient manner for acting
on the inner surface of the roller around the loose axis with sufficient force
to hold the curtain in any required position, and at the same time allow
the curtain to be drawn down by hand independent of the cord as before stated.
