PROVISIONAL SPECIFICATION.
Improvements in Fittings for Blind and other Rollers.
I, JOHN FURNIVAL of 4 Balby Road Doncaster in the County of York Surveyor
and Valuer, do hereby declare the nature of this invention to be as follows
--
The object of my invention is to construct blind and similar roller fittings in
such a way that the blind by means of a single cord may be drawn up or down and
held in any position by an application of parts which I claim to be original as herein
described reference being had to the accompanying drawings. The parts I claim to
be novel are
(1st) A cam wheel forming one side of the pulley round which the cord will run on
the one end of the roller.
.
(2nd) A pin or an arm covered with india-rubber or other flexible material (or not
covered) and so arranged upon the bracket that the cam rides over the pin which forms
a brake to the cam.
(3rd) An arm with eyelet hole for conducting the cord fixed on back of the
bracket.
(4th) A somewhat irregular vertical hole or opening formed in the bracket in which
the axle of pulley is allowed to rise and fall when in action.
The part marked "A" on the drawing accompanying this Specification is the cam
referred to.
The part marked "B" is the pin.
The part marked "C" is the arm and eyelet hole.
The opening referred to in paragraph 4 is marked "D" on the-drawing.
The above described blind roller fittings as arranged in the drawing, or otherwise
arranged to form blind roller fittings are the parts which I claim to be my invention.
Dated this 5th of December 1889.

I JOHN FURNIVAL 4 Balby Road Balby Doncaster in the County of York Building
Surveyor 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 :-
The object of my invention is to construct blind and similar roller fittings in such a
way that the blind by means of a single cord may be drawn up or down and held in
any position by an application of parts which I claim to be novel as herein described.
reference being had to the accompanying drawings.
(1) A pin or arm covered with india-rubber (or not covered) and so arranged upon
a bracket that it forms a break or catch to the wheel.
(2) An arm with eyelet hole for conducting the cord fixed on the back of the
bracket.
(3) A somewhat irregular vertical slot hole or opening formed in the bracket in
which the axle of the pulley is allowed to rise and fall when in action.
The part marked "B" on the drawing is the pin referred to.
The part marked "C" on the drawing is the arm and eyelet hole.
The opening referred to in paragraph 3 is marked "D" on the drawing.

page_text: The described parts when arranged as a whole as shown on the drawing accompany-
ing this specification may be worked and used by attaching a cord to the pulley and
passing the said cord through the hole in the arm "C" the blind being rolled up the
roller. is, then placed in position the cord being pulled somewhat sharply the pin or
axle of the pulley is lifted into the upper half of the hole "D" on drawing and the
cam wheel is at the same time lifted clear of the pin "B" the cord the while being
held lightly and allowed to run through the fingers the blind is then lowered and
stopped at any desired point by a sudden lift of hand and slackening of the cord, the
pin' or axle of the pulley at once drops into the lower half of the opening "D" and
the teeth of the cam wheel 'catch on the pin "B" when the blind is at rest.
When the blind is drawn the cord is wrapped on the pulley wheel the end hanging
in reach of the operator.
In raising the cord is pulled steadily and slackened quickly to stop the blind as
above described.
Having now particularly described and ascertained the nature of this my invention
and in what manner the same is to be perforined I declare that what I claim as my
invention is:-
The bracket "B. D" as marked on the drawing to be my invention as arranged
with the several parts as herein described.
I
(1) The pin as fixed upon the left hand side of the said bracket marked "B" on
the drawing.
(2) The arm marked "()" on the drawing for conducting the cord.
(3) I also claim the particular shape, form, and location, of the opening in the
said bracket and marked "D" on the drawing as described in paragraph 3 sheet two.
