PROVISIONAL SPECIFICATION.
Improvements in Venetian Blinds.
1 PHILIP SALISBURY RYLEY of 61 Claybrook Road, Fulham Palace Road,
Hammersmith, in the County of Middlesex, Carpenter, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to construct and fit Venetian blinds so that the
laths thereof shall be gathered up at the top instead of the bottom as at present
thus doing away with the unsightly bundle of laths in the middle of the window
when the blind is partially drawn up.
According to this invention I gather up the laths by means of the ladders instead
of the cords as is now the case and in order to effect this I dispense with the cords
which run through holes in the laths and which are knotted at bottom, and I make
eyelet holes in the tapes at equal distances apart and near the top of blind I fix
two spindles parallel to each other and on to each of said spindles I key a double
wheel with pegs or pins on its periphery so that upon turning the said spindles
round by any suitable means the pegs or pins will enter the aforesaid holes in the
tapes and thus gather up the laths at top. At the top of the blind and coming at
the side of the tapes I pass over rollers two endless bands (preferably of steel)
and provided with holes so as to be worked by means of the double wheels
aforesaid.
The blind may be drawn up and down by means of an endless chain and chain
wheel arranged so that by pulling one portion of the chain it will revolve the
aforesaid wheels in one direction and on pulling the other portion will revolve them
in an opposite direction.

Improvements in Venetian Blinds.
I PHILIP SALISBURY RYLEY of 61 Claybrook Road, Fulham Palace Road,
Hammersmith in the County of Middlesex, Carpenter, 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 :-
The object of this invention is to construct and fit Venetian blinds so that the
laths thereof shall be gathered up at the the top instead of the bottom as at present
thus doing away with the unsightly bundle of laths in the middle of the window.
when the blind is partially drawn up.
According to this invention I gather up the laths by means of the ladders instead
of the cords as is now the case and in order to effect this I dispense with the cords
which run through holes in the laths and which are knotted at bottom, and I make
eyelet holes in the tape at equal distances apart and near the top of blind I fix
two spindles parallel to each other and on to each of said spindles I key a double
wheel with pegs or pins on its periphery so that upon turning the said spindles
round by any suitable means the pegs or pins will enter the aforesaid holes in the
tapes and thus gather up the laths at top. At the top of the blind and coming
at the sides of the tapes pass over rollers two endless bands (preferably of steel)

aforesaid.
The blind may be drawn up and down, by means of an endless chain and chain
wheel arranged so that by pulling one portion of the chain it will revolve the
aforesaid wheels in one direction and on pulling the other portion will revolve them
in an opposite direction.
And in order that my said invention may be better understood I will refer to the
drawing accompanying this Specification in which :-
Fig. 1 shews view of a blind fitted to a window.
Fig. 2 end view of upper portion of blind shewing my improvements drawn
enlarged.
Fig. 3 shews the arrangement for turning the laths.
Fig. 4 dovetail piece to hold blind up.
Fig. 5 section of same.
The same letters denote the same parts in all the views:-
a shews the top of blind into which the dovetail pieces cc slide and in each of
these pieces c c I mount a roller d d for the tapes e e that pass round the top lath f
of the blind to work on so that the laths may be turned as desired. 9 g are rods or
spindles capable of revolving in bracket pieces h h these pieces are hinged at ii so
as to open when it is desired to take the blind down as hereafter described. On to
each of the rods g g I fix two wheels k. k. provided with spikes the wheels k k are
so fixed that the spikes take into eyelet holes or holes m'in tapes n of the ladders
which supports the laths o I also fix two more wheels p p on the rods g g and under
these wheels p p I pass steel bands qq having holes therein, the bands 99 also
pass over rollers s s mounted on top a of the blind.
t is a rod provided with arms u u to the top of the rod t I fix a cord v passing
over rollers w w. x is a pulley or chain wheel over which I pass an endless cord or
chain y for raising and lowering the blind.
The action is as follows:-
Upon pulling the outer end of the endless cord or chain y the rods or spindles g g.
will turn the wheels k. k. the spikes 1 taking into the eyelets or holes m will collect
the laths of the blind at the top as shewn in Fig. 1 of the drawing.
In order to turn the laths the cord vis pulled which raises the rod t and arms u u
which take under two of the laths as shewn clearly at Fig. 3 and reverses the said
laths. The blind may easily be taken down for cleaning or repairs by drawing out
the dovetail fork pieces c c aud opening the bracket pieces h h so as to allow the
rod or spindle 9 to come out. I propose to have an ornamental plate across the top
so as to hide the mechanism and also the laths when collected up.
2 shews
The blind will stop at any height without any attachment whatever.
angle pieces fixed to the brackets h, h, so as to overlap tapes n, in order that the
spikes may be compelled to take in the eyelet holes m.
Fig. 6 shews how my improved blind is fitted at bottom to adapt it to roofs of
conservatories and like purposes the upper portion being the same as at Fig. 1.
In this case I mount a rod or spindle 1 at bottom of roof on which I fix two
pulleys 2 also chain wheel 3 for endless chain y to pass under so as to turn the
spindle and to the bottom of blind I fix one of the ends of cords 4 these cords or
chains being of sufficient length to allow the blind to be drawn fully up.
other ends of said cords or chains I fix to the pulleys 2, 2, so that as the
spindle is turned in one direction, it will wind the cords or chains 4 on
the pulleys 2, 2 thus pulling the blind down, aud the reverse action will pull the
blind up.
The
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. In Venetian blinds the combination of the wheels k. k. with spikes / and eyelets
or holes m in the tapes n of the ladders for the purpose set forth.

or holes m in the tapes n of the ladders, together with bands q. q for the purpose
set forth.
3. Venetian blinds constructed substantially as set forth.
