NEW OR IMPROVED FURNITURE FOR WINDOW AND OTHER BLINDS
Year: 1859

page_text: LETTERS PATENT to William Newman, of Aston, near Birmingham, in.
the County of Warwick, Brassfounder, for the Invention of "NEW OR
IMPROVED FURNITURE FOR WINDOW AND OTHER BLINDS."
Sealed the 1st April 1859, and dated the 18th January 1859.
PROVISIONAL SPECIFICATION left by the said William Newman at the
Office of the Commissioners of Patents, with his Petition, on the
18th January 1859.
I, WILLIAM NEWMAN, of Aston, near Birmingham, in the County of
Warwick, Brassfounder, do hereby declare the nature of the said Invention:
for "NEW OR IMPROVED FURNITURE FOR WINDOW AND OTHER BLINDS," to be
as follows:-
My said Invention consists of the mechanism herein-after explained,. for
raising, lowering, and adjusting window and other blinds; the end of the roller
to which the cord is attached works in a bearing made in a lever fixed in a
nearly upright position. The blind cord after passing around. the pulley on
the end of the roller, passes over a small pulley fixed over the roller, and
hangs down vertically.
When the cord is pulled, the lever in which the end of the roller works is
first moved upon its joint, and a tooth or click which had engaged in a
ratchet wheel on the roller axis is lifted from the said ratchet wheel. The
roller is now at liberty to move, and by pulling the cord, the blind may be

page_text: raised, or by gently letting it go the blind may be lowered. By loosing the
string wholly the blind comes to rest, for when there is no force applied to the
cord, the roller and the lever in which the axis of the roller works return to
their original position, and the click or pall falling into the ratchet wheel, the
motion of the roller is arrested.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Newman in the Great Seal Patent Office on the
9th July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
NEWMAN, of Aston, near Birmingham, in the County of Warwick, Brass-
founder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Newman, Her special licence that I, the said William
Newman, my executors, administrators, and assigns, or such others as I, the
said William Newnan, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "NEW OR
IMPROVED FURNITURE FOR WINDOW AND OTHER BLINDS," upon the condition
(amongst others) that I, the said William Newman, my executors or admi-
nistrators, 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 William Newman, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My said Invention consists of the mechanism herein-after described and
illustrated in the accompanying Drawing, for raising, lowering, and adjusting
window and other blinds.

page_text: Figure 1 of the accompanying Drawing, represents in front elevation a
roller blind and furniture to which my Invention is applied; Figures 2 and 3
represent in end elevations the right and left-hand ends respectively of the
blind furniture, Figure 1; Figure 4 represents an end elevation of the end,
Figure 3, seen from the opposite side; Figure 5 represents a transverse
vertical section of Figure 1, taken through the line b; Figure 6 represents a
transverse vertical section, taken through the line c, Figure 1; and Figure 7
represents a longitudinal vertical section of the right-hand portion of the blind
furniture represented in Figure 1, the roller and parts connected therewith
being in elevation; Figures 8, 9, and 10 represent portions of my Invention,
as herein-after explained, the same letters indicate the same parts in the
several Figures. d is the roller, to which the blind is attached in the usual
manner; one end d² of the said roller d, works in a bearing made in the
bracket e, and the other end d³ of the said roller d, works in a bearing f made
in the lever g, fixed in a nearly upright position upon the bracket h. The
said lever g is represented separately in front and side elevations in Figure 10.
The said lever g turns upon a joint or centre at i, (see Figures 6, 7, and 8),
and when the roller d is stationary, the upper end of the said lever rests
against a shoulder k (see Figure 6) on the bracket h. Above the said lever g
is a pall or click n, working freely on the centre n², on the bracket h. When
the said lever g is in the position represented in Figures 1, 6, and 7, the said
pall or click n engages with the teeth of the ratchet wheel o on the axis of the
roller d, and prevents the rotation of the said roller d. The said pall or click n
is shown separately in Figure 9; 1 is the blind cord, which, after passing
around the pulley m, on the end of the roller d, passes over a small pulley or
roller P fixed over the said roller d, and hangs down vertically, as seen in
Figures 1 and 5. When the cord 7 is first pulled, the lever g, in which the
end of the roller d works, is moved upon its centre or joint i, and raised or
displaced from the position represented in Figures 6 and 7, to that represented
in Figure 8. On the raising of the said lever g, its upper side g² engages
under a shoulder n³ (see Figure 9) on the pall or click n, and lifts or raises
the pall or click into the position represented in Figure 8. The said pall or
click n is thereby disengaged from the teeth of the ratchet wheel o. The
roller is now at liberty to move, and by the further pulling of the cord 1, the
blind may be raised, or by gently letting it go, the blind may be lowered.
When the blind has been raised or lowered to the required distance by loosing
wholly the cord 1, the blind comes immediately to rest, that is to say, on
loosing the cord l, the roller & being no longer held in its raised position, the
said roller returns to its original position, carrying with it the lever g, in which

page_text: .one end of the said roller. works, and the pall or click n being no longer
supported by the lever g, falls and engages with the teeth of the ratchet
wheel o, and arrests the motion of the said roller d. The end d², of the
roller d is prevented from escaping from its bearing in the bracket e by a
lever turning on the centre r, as in ordinary blind furniture.
Having now described the nature of my said Invention, and the manner
of carrying the same into effect, I wish it to be understood that I do not
limit myself to the precise details herein described and represented, in the
accompanying Drawing, as the same may be varied without departing from
the nature of my Invention; but I claim as my Invention the new or improved
furniture for window and other blinds, herein-before described and represented
in the accompanying Drawing, that is to say, blind furniture in which, by the
pulling of the blind cord, one end of the roller axis is raised or displaced, and
the mechanism by which the running down of the blind is prevented, thereby
thrown out of action, the blind being raised or lowered by pulling or gently
letting go the said cord, and fixed or adjusted by loosing the said cord when
the blind is in the desired position.
In witness whereof, I, the said William Newman, have hereunto set my
hand and seal, this Eighth day of July, in the year of our Lord One
thousand eight hundred and fifty-nine.
