A NEW OR IMPROVED METHOD OF HOLDING OR SECURING VENETIAN AND OTHER BLINDS IN ANY DESIRED POSITION."
Year: 1873

page_text: LETTERS PATENT to John Partridge, the younger, of the City Road,
Saint Luke's, in the County of Middlesex, Window Blind
Manufacturer, for the Invention of "A NEW OR IMPROVED METHOD OF
HOLDING OR SECURING VENETIAN AND OTHER BLINDS IN ANY DESIRED
POSITION."
PROVISIONAL SPECIFICATION left by the said John Partridge at
the Office of the Commissioners of Patents, with his Petition, on
the 2nd October 1873.
I, JOHN PARTRIDGE, the younger, of the City Road, Saint Luke's,
in the County of Middlesex, Window Blind Manufacturer, do hereby
declare the nature of the said Invention for "A NEW OR IMPROVED
METHOD OF HOLDING OR SECURING VENETIAN AND OTHER BLINDS IN ANY DESIRED
POSITION," to be as follows:-

page_text: either partially or wholly drawn up; and to supercedo the present
unsatisfactory mode of securing raised blinds in position.
The means by which I propose to attain the said object of my present
Invention are as follows:-Immediately under the draw end of tho
"blind head" or pulley picce I fix to and across the said blind head a
metal, bracketted, or flanged shoe, having a cranked eccentric lever and
bar pivotted or turning in recesses in the brackets or sides of the said
shoe, leaving sufficient space between such bar and the inside of the
cross piece of the metal shoe for the cords of the blind to pass freely
when the apparatus is in its normal state. To the free end of the
said lever a check line is attached of sufficient length to be within
reach of the hand.
When it is desired to secure the blind in any position it is first
raised or lowerd to such position, then by pulling the check lino
downwards the cranked lever is made to turn its cross bar so that the
free edge thereof presses the cords of the blind against the inside of the
cross piece of the metal shoe, and thus holds the blind in the desired
position until it is released by pulling the blind cords downwards; this
latter motion turns the said cross bar edge downwards and thus relieves
the blind cords from its pressure.
My improved arrangement or apparatus can be attached to blinds
now in use, generally without unfixing them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Partridge in the Great Seal Patent Office on
the 2nd April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PARTRIDGE, the younger, of the City Road, Saint Luke's, in the County
of Middlesex, Window Blind Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of October, in the year
of our Lord One thousand cight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Partridge, the younger,

page_text: Her special licence that I, the said John Partridge, the younger, my
executors, administrators, and assigns, or such others as I, the said John
Partridge, the younger, 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 "A NEW OR IMPROVED METHOD OF HOLDING OR SECURING VENETIAN AND
OTHER BLINDS IN ANY DESIRED POSITION," upon the condition (amongst
others) that I, the said John Partridge, the younger, 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 John Partridge, the younger, 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 :-
The object of this Invention is to hold or maintain Venetian and
other blinds to windows, doors, and the like in any desired position,.
either partially or wholly drawn up; and to supercede the present
unsatifactory mode of securing raised blinds in position.
The means by which I propose to attain the said object of my present
Invention as applied to any ordinary Venetian window blind, I now
proceed to explain with the aid of the accompanying Drawing which
forms part of this Specification, reference being made thereto by the
numerals and letters marked thereon, which reference applies to cach
Figure of the said Drawing where the same index numerals and letters
appear.
Figure 1 shews my improved apparatus as seen when fixed in place.
at the draw end of the blind head or pulley piece, herein-after called the
pulley piece; Figure 2 is a horizontal plan of the under side of the
same.

page_text: Figure 4 is a transverso section of the moveable bar or lever, heroin-
after called the holding lever, on the lines A, B, Figure 2, and C, D,
Figure 5; Figure 5 is an clevation of the said holding bar.
Figure 6 is a transverse section of the holding apparatus when in its
normal state, and the blind is free to fall or move downwards or bo 5
drawn upwards; Figuro 7 is the same showing the holding apparatus in
operation, and the blind secured or held in position.
The pulley picce a is fixed to the upper part of the window frame as
usual, and is provided in this example with three pullies b, in the
grooves of which runs the blind cord c. Under and near the draw end 1
of the pulley piece a I fix thereto a bracketted or flanged shoe d; in
recesses or bearings formed in the said shoe is fitted the moveable
holding lever e, so as to leave sufficient space between such lover e and
the inside of tho shoo d for the cords c to pass freely when the apparatus
is in its normal state, sec Figure 6. The holding lover e is provided 1
with a handle or lever e¹ to which is attached a check cord f.
In operating my improved apparatus it is only necessary, by means of
the check cord f, to pull the lever e¹ downwards from its normal stato,
as shown in black line in Figure 1, to the position shown in red lino in
the same Figure, which causes the holding lever e to be moved from the 2
position shown in Figure 6 to that shown in Figure 7, where it will be
seen the blind cord c is tightly pressed between the edge of the holding
lever e and the insido of the shoo d, which is here shewn to be notched
for the more securely gripping the blind cord. When the blind cord is
thus tightly pressed the weight of the blind holds the lever e in position, 2
and the greater the weight of the blind the greater is the pressure of
such lover on the cord. The lever e is released by pulling the cord c
downwards, when the latter is set free and the blind can be lowered or:
otherwise moved as desired.
My said improved arrangement or apparatus can be attached to blinds 3
now in use generally without unfixing them.
Having thus fully described and illustrated the nature of my said
Invention, and the method of performing the same, I claim as new
and desire to secure by the before-mentioned in part recited Letters
Patent, the method of holding Venetian and other blinds in any 3
'

page_text: desired position, substantially as herein described and shown in the
Drawing.
In witness whereof, I, the said John Partridge, the younger, have
hereunto set my hand and seal, this Thirtieth day of March,
in the year of our Lord One thousand eight hundred and
seventy-four.
