County of Devon, Engineer, for the Invention of "IMPROVEMENTS

PROVISIONAL SPECIFICATION left by the said Henry Burgess Young
at the Office of the Commissioners of Patents, with his Petition,
on the 12th January 1871.
I, HENRY BURGESS YOUNG, of Barnstaple, in the County of Devon,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF WINDOW BLIND MOUNTINGS AND IN
APPARATUS CONNECTED THEREWITH," to be as follows:-
These improvements relate to certain apparatus by which the level;
of the blind roller may be regulated so that the blind may hang per-.
pendicularly; also to the governance of the movement of the roller in.

being caused to rotate in either direction or in holding the same
stationary. On the outside of the bracket which is fixed to the window
frame is a projection through which a vertical hole is made. In this
hole the shank of the bearing which carries the spindle at one end of
the roller is free to move and can be moved in a vertical direction,
either by means of a separate screw in the projection or by being itself
screwed into the projection, and by this means the roller can be brought
level.
The roller is caused to rotate in the following manner :-The reel
end spindle is carried upon a spring bearing attached to the bracket
which is fixed to the window frame. This spring presses the periphery
of the cord reel up against a block of leather or other suitable material
and prevents the blind unrolling when left to itself. The end of a cord
is fastened to the barrel of the reel, and by pulling down the blind by
the lath causes the cord to be reeled up. To raise the blind the cord
is pulled, the pressure of so doing is sufficient to press down the reel
and disengage it from binding against the leather block, and the blind
can be drawn up. As soon as the cord is loosed the spring presses the
reel up against the block and holds the blind in the position in which it
happens to be at that moment. There is a stop on the bracket which
prevents excessive deflection of the spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Burgess Young in the Great Seal Patent
Office on the 12th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BURGESS YOUNG, of Barnstaple, in the County of Devon, Engineer,
Bend greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of January, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant. unto me, the said Henry Burgess Young, Her special
licence that I, the said Henry Burgess Young, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Burgess

page_text: Young, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter.
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
" IMPROVEMENTS IN THE CONSTRUCTION OF WINDOW BLIND MOUNTINGS AND IN
APPARATUS CONNECTED THEREWITH," upon the condition (amongst others) that
I, the said Henry Burgess Young, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Burgess Young, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :—
These improvements relate to certain apparatus herein-after particu-
larly described and illustrated by the Drawings accompanying these
Presents, by which the level of the blind roller may be regulated so
that the blind may hang perpendicularly; also to the governance of the
movement of the roller in being caused to rotate in either direction or
in holding the same stationary.
In order that the nature of my said Invention may be thoroughly
understood, and in order to fully explain in what manner the same
is to be performed or put in practice, I will at once proceed to
describe the same by reference to the accompanying Drawings as
follows:-

page_text: at a right angle to the axis of the blind roller. The same letters will
refer to similar parts in Figs. 1, 2, 3, 4, 5, 6.
The cord reel spill a is carried by a bearing at the end of the spring b,
which is attached to the bracket frame c by a screw or rivet d; e is a
block of leather or other suitable material fixed to the frame c; f is a 5
guard bar to prevent the blind cord g from riding over the edge of the
cord reel h. A projection i on the frame keeps the side of the cord
reel clear of the spring. One end of the cord g is fastened to the barrel
of the cord reel.
The action of the apparatus is as follows:-Pulling down the blind 1
by the lath causes the cord to be reeled up. To raise the blind the cord
is pulled; the pressure of so doing is sufficient to press down the reel
and disengage it from binding against the leather block and the blind
can be drawn up. Instantly the cord is loosed the spring presses the
reel against the block and holds the blind in the position in which it 1
happens to be at that moment.

of one method of regulating the level of the blind roller. .a, bracket
frame; b, bearing carrying the end of the blind roller c, and having a
shank e, which fits into but is free to slide in a socket in the bracket 2
frame. The level of the blind roller is regulated by the screw f.
Fig. 10 is a end view; Fig. 11 is a top view; Fig. 12 is a front
view of another method of regulating the level of the blind roller.
a, bracket frame; b, bearing carrying the end of the blind roller c
and having a screw shank e, by screwing which into or out of the 2
tapped hole in the bracket frame a can be made to regulate the level
of the blind roller.
Having now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same may be
performed or carried out in practice, I hereby declare that I claim, the
herein described "Improvements in the Construction of Window Blind
Mountings and in Apparatus connected therewith," in which an im-
portant feature is supporting the spindle of the blind pulley by a spring
arranged and acting in manner substantially as herein described and
illustrated by the Drawings accompanying these Presents, it being
understood that I do not confine or limit myself to (nor do. I claim

page_text: except when combined and used substantially in manner described) the
use of the subsidiary details of construction herein described and shown
by the accompanying Drawings.
In witness whereof, I, the said Henry Burgess Young, have here-
unto set my hand and seal, this Eleventh day of July, in
the year of our Lord,One thousand eight hundred and seventy-
one.
Witness,
