Pianoforte Maker do hereby declare the nature of his invention for THE IMPROVE-
MENT IN VENITIAN OR LATHI BLINDS to be as follows:-
To,accomplish this I.form a Trellis or Lattice web it being fastened togather by
rivets or screws and some of the rivets being hollow like an Ilethole for tho
purppose of joining each web or joining web to lath's. I place those web's each
side or at each end of Laths When the blind is down the web is extended to its
full length and all the lathi's are separated, but as soon as you commence lifting
it from, the bottom all the lath's begin to contract through the formation of the
Trellis or Lattice web Each lath is supported or kept in its place by a screw,
cord, tape or wire passing through the Ilethole rivets before mentioned To
obviate or lessen the weight of blind when drawn up I use springs or balance
weight's acting upon the Lattice web Laths Cords or Chain. In constructing this
web I sometimes arrange the angles of the web so if I want the blind, laths to
close up at top bottom or middle I can do so by the different lengths and angles
of Trellice web. The web will be made of metal or other fit material.

ALFRED SQUIRE.

page_text: I ALFRED SQUIRE of 6 Wrotham Rd Camden Rd in the County of Middlesex
Piano-forte Maker, do hereby declare the nature of his 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 my invention is gitting an equal light through the laths of blind's
at any position it may be placed, and doing away with the collecting of lath's at
bottom of blind's as is now the case in Venetian class of Blinds, To accomplish
this I form a Trellice or Lattice webb, it being fastened togather by rivets or
screws, and some of the rivets being hollow like an Ilet hole for the purpose of
joining each webb or joining webb to lath's. I place these webbs each side or at
.each end of lath's. When the blind is down the webb is extended to its full length
and all the lath's are seperated, But as soon as you commence lifting it from
the bottom all the laths begin to contract through the formation of the Trellice or
Lattice webb, Each lath is supported or kept in its place by a screw, pin, cord,
tape or wire passing through the Ilet hole before mentioned, To obviate or
lessen the weight of blind. when drawn up I use Spring or balance weight acting
upon the Lattice webb lath, cord or chain, In constructing this webb I sometimes
arrange the angles of the webb so if I want the blind laths to close up at top,
bottom or middle I can do so by the different length's and angles of Trellice webb
before mentioned, The webb will be made of metal or other fit material, and my
Invention is clearly represented in the annext Drawing. A the laths" "B the
rivets in webb "O the Ilet hole rivets " "D the Compensating Springs"
"E Trellice or Lattice webb "F holes in lath" "G wide tube centre used in
open webb,
"Fig. 1" is the drawing of my improved blind expanded showing
'action of webb "E" and compensating spring "D" "Fig. 2" lath shown flatways
with two holes "E" at each tape thereby illustrating the method of securing lath
to webb by means of tapes, wire or cord also section shown, "Fig. 3" webb shown
on the flat with Ilet holes C" other rivets "B.". This webb is not constructed
the same as in "Fig. 1" This is what I call an open webb and my reason for so
forming this webb is to obtain greater contracting power than the one before
mentioned 'E" "Fig 4" is the same as "Fig. 3" only it is shown on its edge
what I call the open webb and it will be well understood by all mechanics how,
G" being
1 obtain greater contraction by this method, The wide tube centre
used, Fig. 5 shows another method of forming webb so as to cause the laths to
collect at bottom, top or middle of blind. This also can be well understood as the
distance of the centres are more or less, which causes the lath's in blind to contract
according to the position of the centering of the before mentioned webb I do not
confine myself to the precise showing of position or number of spring as I elect
to place them on any part of webb or Laths as circumstances may require according
to weight of blind, and should I prefer weights in place of springs or both this
also I reserve to my right of using, the weight being applied by the ordinary
method of cord, chain or wire and wheel in top rail to raise blind, the before
mentioned weights to run into pockets or tubes,
"

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st The application of the centred webb what I call the Trellice or Lattice webb
togather with the manner of Ilet holes to secure lath's to webb.
2nd The application of Spring or weight to compensate the weight of blind.
3rd The manner of securing the webb to lath's with screw, pin, tape, cord or
wire through the Ilet hole in webb.
4th The different methods of constructing webbs as shown in the annexed
drawings.
5th The application of wood or metal to form webb for blinds and the running
of weights in tubes or pockets.
