WILLIAM LORD Ventilator Manufacturer 14 Marsh Road Middlesbro Yorkshire do
hereby declare the nature of this invention to be as follows:-
On a bracket I provide a short arm fixed in position by a screw or rivit, the arm
being free to move in a short radius, the tendency of this arm is to fall to the locking
stud on the bracket. In the free end of arm I provide an hole or bearing for the
spindle of ratchet wheel to revolve in. The weight of Blind and roller retains the
ratchet wheel in contact with the stud on the bracket and locks it. If a cord wound
on the ratchet wheel barrel, be pulled it will draw the arm with the ratchet wheel on
from the stud, and the blind will be free to move up or down. If the cord be released,
the blind will be locked.
The spindle of ratchet wheel may be in position above the Bracket, or under as the
case may be.

Improvements in Window Blind Fittings.
WILLIAM LORD 14 Marsh Road Ventilator Manufacturer Middlesbro I 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:
On a bracket A figures 1 and 2 of the accompanying drawings, I provide a move-
able arm secured on a bracket by a screw or rivet P. In the free end of the arm I
provide a hole or bearing for the axle of ratchet to rotate in, the arm C is made so

page_text: °
that it always is inclined, when complete with roller and blind, to fall to the pawl,
catch, or stop at I figures 1, and 2. When it is preferred to make the ratchet wheel
to depend to the lower part of bracket, I provide a moveable cord guide H figure
that will guide the cord on the barrel at any angle necessary, over a pulley or through
a hole H figures 1 and 2. Figure 2 illustrates the apparatus when the ratchet wheel
spindle is above the bracket and the ratchet wheel falling into contact with the pawl,
stop or catch I figures 1 and 2. H¹ figures 1 and 2 is the hole or pulley through
which the cord is guided when running on or off the barrel F. R figures 1 and 2
are the holes to secure the bracket on the wood or other work. L figures 1 and 2 is
the blind. M. figures 1 and 2 is the cord to draw up the blind or to release the blind
as the case may be. G is the socket or rim in which the roller end is inserted
figures 1 and 2. K is a stop to prevent the arm being drawn too far over. Figures 3
and 4 illustrate the method adopted in making the ratchet wheel, barrel and flange or
cord-holder combined. S is the shaft on which the socket with the flange combined
slips on, figure 3, the axle E extending through the flange at J figure 4. N N are
the screw holes to secure the flange on and to prevent it turning round and to which
the cord may be attached. Figure 7 shows a plan of figure 4. Figure 6 shows the
flange without the socket there being the flange only to screw on with two or three
screws. fig. 3 shows the roller end fixed in the rim of the ratchet wheel.
The action of these window blind fittings are as follows. If the cord M figures 1,
and 2 be pulled the arm will be drawn over with the ratchet wheel to the stop K. lf
the cord be held with a little tension the blind will immediately fall. If the cord be
released the blind will come to rest, the arm C with the ratchet wheel falling towards
the pawl, stop or catch I figures 1, and 2, thus obeying the law of gravity, and the
ratchet wheel becomeing locked at I figures 1, and 2. In applying these fittings to
venetian blinds, it will be necessary to attach the cords passing through the laths to the
roller, and on drawing the cord the blind cords will be wound on the roller, and
the blind drawn up in the usual way.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :-
:-
1st. I claim the fittings substantially as described to be applied to windows for all
kinds of blinds wound on rollers, or they may be adapted to venetian blinds if
preferred.
2nd. I claim the combination of the various parts substantially as described, in
making the ratchet wheel, and cord holder, with, or without socket to be applied to
window blinds such as described in provisional Specification.
