PROVISIONAL SPECIFICATION.
Improvements in and applicable to Venetian Blinds.
I, CHARLES GARDINER of 73 West Green Road South Tottenham Middlesex
Printer do hereby declare the nature of this invention to be as follows:-
An improved method of drawing up Venetian blinds by which the laths
accumulate at the top, instead of the bottom thus obviating the dark shadows and
obstruction of light, usual with ordinary Venetian blinds when partially
drawn up.
My method is to add an extra tape to each rund of the ordinary tape ladder,
such extra tape to be used above, instead of under the laths, thus, by placing any
lath between the upper and lower tapes with a cord at each side attached by knots
or otherwise, any one or more sections of the laths may be drawn up and secured
to the top of the blind as desired-the cords pass through pulleys over the top to
side of blind for drawing up purposes in the ordinary manner.
By my method, the construction of the blinds is much simplified neither clamps,
grips, levers, screws or other similar contrivances being neccessary.

I, CHARLES GARDINER of No. 73 West Green Road South Tottenham
Middlesex Printer 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 :-
An improved method of drawing up Venetian blinds, by which the laths may
accumulate at the top, instead of the bottom.
My method is, to add extra tapes to two or more rundles of the ordinary tape
ladders, such extra tapes to be placed above, instead of under the laths-thus, by
placing any lath between the extra tape and the ordinary one, with a cord attached
at each side as described below, any one or more sections of the laths, may be
drawn up; and secured to the top of the blind, as desired.
That my invention may be clearly understood, I have illustrated examples by
the accompanying drawings.
Fig. 1, represents a portion of an ordinary sized Venetian blind lath, shewing the
position of the extra tape (a).
I draw up the blinds in two, three, or more sections, according to length, each
section consisting of about ten laths (more or less) a similar extra tape, Fig. 1(a)
being used upon the top lath of every section; at both sides, and if desired
in centre.

page_text: Openings are pierced in the laths in the ordinary way, for the cords to pass
through Fig. 1 (b), but across such openings I fix a wire bar (c) to which by
means of a metal hook or swivel (d) I attach the drawing up cords (e) the said
hook or swivel working over the wire bar from side to side, assists the shading
process, which is worked from the left of blind as hitherto.
The cords pass over the top rail (or pulley head) of blind, Fig. 2 (f) in the
ordinary way, but instead of using separate "pulleys" for each cord, I use one or
more "rollers" Fig. 2 (g) sufficiently wide, to carry several cords-this prevents
the possibility of their slipping out of place, or between the pulleys, and insures
their free run.
At the pulling end of the cords of each section, Fig. 3 (h) I attach a ball or
weight () which, assisted by the rollers Fig. 2 (g) carries down all cords together
(whether in use at the moment or not) and prevents their clogging amidst the
laths accumulating at the top of blind.
The balls or weights Fig. 3 (i) have an opening through the centre (as in a
bead) (k) which enables the pulling up cords of a second section, to pass through
the ball or weight of the first section, and those of a third section to pass through
that of the second section, and so on, hence, the drawing up and fixing of one
section, in no way interferes with that of another.
If 'preferred, the balls or weights may be detached, and suspended separately.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is-
(1.) The use of additional, or upper tapes, to the rundles, or "cross tapes" of
the ordinary tape ladders, Fig. 1(a).
(2.) The use of "wire bars "Fig. 1 (c) across the cord openings in laths,
Fig. 1 (b) to assist shading process.
(3.) The use of movable hooks or swivels, Fig. 1. (d) for the purpose of
attaching or detaching the cords (e) from the wire bars Fig. 1 (c).
(4.) The use of balls or weights Fig. 3 (1). (perforated) so as to give a free run
to the cords of the different sections.
(5.) The substitution and use of "rollers," Fig. 2 (g) instead of "pulleys," for
carrying the corde over the top rail, or "pulley head" Fig. 2 (f).
(6.) The method herein described, of drawing up Venetian blinds in sections.
