page_text: LETTERS PATENT to Joseph Everard of Birmingham in the County of
Warwick Brassfounder for an Invention of "IMPROVEMENTS IN THE MODE
OF AND APPARATUS FOR RAISING AND LOWERING OF FESTOON, VENETIAN, AND
OTHER BLINDS
PROVISIONAL SPECIFICATION left by the said Joseph Everard at the
Office of the Commissioners of Patents on the 21st February 1882.
JOSEPH EVERARD, of Birmingham, in the County of Warwick, Brassfounder.
"IMPROVEMENTS IN THE MODE OF AND APPARATUS FOR RAISING AND LOWERING OF
FESTOON, VENETIAN, AND OTHER BLINDS."
My invention relates to the construction or arrangement of parts for raising or
lowering of festoon, venetian, and other blinds in a simple and efficacious manner.
I will describe my Invention as applied to a venetian blind. To the hanging
bar (being that part which carries the pulleys and socured to the upper part of
the window frame) and to the under surface of one end I affix my apparatus
which consists of the following construction.
A frame consisting of a back which is slotted lengthwise and bevelled on the
edges exteriorly and interiorly; two ends which carry a lever by means of pins
passing through the said ends, and eccentrically suspended in cross section this
lever is pippin shaped, and this is provided with a looped lever by means of
which it is actuated, as afterwards described.
The frame and its lever is so arranged at the end of the hanging bar that the
cords which pass over the pulley wheels are fed between the back of the said
frame and the said lever in a vertical position and free; so that by means of the
cords above described the blind can be raised or lowered with facility, but to
maintain or affix in or at any desired position the loop of the lever being provided
with a single cord and by a downward pressure will raise the eccentric lever to an
horizontal line and opposite the slot, carrying and compressing the two cords to
the bevelled edges, but without injury, by applying a downward pressure to the
two cords the eccentric lever is brought to its normal position.

"IMPROVEMENTS
IN THE MODE OF AND APPARATUS FOR RAISING AND LOWERING OF FESTOON, VENETIAN,
AND OTHER BLINDS.
My Invention relates to the construction or arrangement of parts for raising or
lowering of festoon, venetian and other blinds in a simple and efficacious manner.
I will describe my invention as applied to a venetian blind. To the hanging
bar (being that part which carries the pulleys and secured to the upper part of
the window frame) and to the under surface of one end I affix my apparatus
which consists of the following construction:-
A frame consisting of a back which is slotted lengthwise and bevelled on the
edges exteriorly and interiorly; two ends which carry a lever by means of pins
passing through the said ends, and eccentrically suspended, in cross section this
fever is pippin shaped, and this is provided with a looped lever by means of
which it is actuated, as afterwards described.
The frame and its lever is so arranged at the end of the hanging bar that the
cords which pass over the pulley wheels are fed between the back of the said
frame and the said lever in a vertical position and free, so that by means of the
cords above described the blind can be raised or lowered with facility, but to
maintain or affix in or at any desired position the loop of the lever being provided
with a single cord and by a downward pressure will raise the eccentric lever to a
horizontal line and opposite the slot, carrying and compressing the two cords to
the bevelled edges, but without injury, by applying a downward pressure to the
two cords the eccentric lever is brought to its normal position.
The before going being the nature of my invention, I will proceed to describe in
detail how the same may be carried out in practical effect, and for that purpose
I have hereunto attached a sheet of drawings illustrative thereof marked with
figures and letters of reference corresponding with those in the following
explanation, the same letters of reference being used to denote like or corresponding
parts throughout the various views of the Drawings.
Fig. 1 is a view, isometrical, shewing the action when fixed. Fig. 2 front view
elevation, with lever in position as at d. Fig. 3 a back view with lever as at d.
Figs 4 and 5 views in section, clevation.
Fig. 6 a front view elevation of single cord retainer. Fig. 7 side elevation of
same. Fig. 8 back elevation. Figs 9 and 10 shew respectively the cord released
and secured. Figs 11 and 12 side view and front view respectively of lever
detached.
a is the frame, with slot b, and its edges bevelled, to prevent injury to the cord
when secured. The ends c form brackets and carry the pippin shaped lever d
(so far as relates to Figs 1, 2, 3, 4, 5,) which is supported and works freely in the
said brackets by means of the pin e being eccentrically arranged. is a loop
acting as a lever for actuating the same, by affixing the cord g thereto. In Figs 6,
7, 8, 9, 10, 11, 12, the cord g is dispensed with and loop f, the lever h being
altered in its configuration only, so far as to allow of its being manipulated for the
securing or releasing of the cord i.
Fig. 1 illustrates this invention practically, i the blind cord passing over the
pulley-wheels as hitherto, the check cord g having been employed, the lever dis
raised to a horizontal line and secured, as Fig. 5. Fig. 4 shews the blind cords

page_text: Having thus described the nature of my said invention, its object and purpose,
and shewn how the same may be carried out into practical effect, nevertheless I
wish it to be understood that I do not confine myself to the precise details of
construction, which may be modified without departing from the essential
principle of the said Invention, but what I desire to claim and have secured to me
by the herein before in part recited Letters Patent for "Improvements in the mode
"of and apparatus for raising and lowering of festoon, venetian, and other blinds,
. are as follows:-
The general construction of the lever in combination or arrangement with other
parts, substantially as herein before described and shewn on drawings, or any
merc modification thereof.
In witness whereof I the said Joseph Everard have hereunto set my
hand and seal this eighteenth day of August in the year of our Lord.
one thousand eight hundred and eighty two.
Witness.
