Improvements in Pulley-fittings for venetian-blinds.
I, ARTHUR ELLWOOD, of East Barnet Road, New Barnet, Herts, Joiner, 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 :-
This invention relates to improvements in pulley-fittings for Venetian-blinds, and
has for its object to so fix the pulleys over which pass the cords for raising and
lowering Venetian-blinds, in the immovable horizontal heads, that such pulleys will
work in a more efficient manner than heretofore, while at the same time the said
cords will not be liable to wear away the wood-work composing the said heads,
adjacent to such pulleys, a further object being to render the removal and renewal
of the said pulleys, an easy and speedy operation.
And in order that this, my invention may be the more fully understood, and
readily carried into effect, I have made reference to same upon the accompanying
sheet of illustrative drawings, wherein :
Fig. 1 is a side elevation of a double pulley-fitting in accordance with my
invention
Fig. 2 being an end view thereof.
Fig. 3 is a plan of a single pulley-fitting,
Fig. 4 being a side elevation thereof, while
Fig. 5 is a perspective view shewing the fittings arranged in the horizontal
immovable head from which the blind is suspended.
Referring to the drawings in which like letters of reference indicate
corresponding parts throughout the several figures, a is a plate provided with
depending brackets a' on each side, to support the spindle 6' upon which the
pulley (or pulleys) revolves.
b
In the case of the double pulley-fitting over the pulleys of which the double
cord c, passes and which pulley-fitting is usually fixed at the right-hand side of a
window, the said plate a is provided with one of these said depending brackets a¹
on each side of, and with a similar bracket a² in the centre of such plate.
The said plate a. is provided with two parallel slots a³ formed at right angles to
the said supporting-brackets a' a' through which slots a³, the pulleys b project
above the surface of the plate a, to enable the cords c to run freely over such
pulleys without coming into contact with the plate, the said brackets a¹ being
situated to the outside of such slots a³, while the central supporting-bracket a² is
situated between the said slots, as illustrated.
The spindle 6 is passed through the centres of the pulleys b, which are adapted
to freely revolve upon same and secured in any suitable manner to the said
supporting-brackets a¹ a², the plate a then being fastened by screws d or their
equivalent, to the horizontal immovable head e, the usual recess or recesses being
provided in the latter, for the said pulleys to work in. In the case of a single
pulley-fitting, such as illustrated more particularly by Figs. 3 and 4, only one slot
is provided in the plate a, and the spindle & is mounted between the two
supporting brackets a', the central bracket a³ shewn in Figs. 1, 2, and 3, being
dispensed with.
The pulley-fittings are equally applicable to blinds where it is desirable to
employ three or more pulleys to each fitting, as well as to the single and double
forms herein before described and shewn by the drawings.

page_text: The plates a may be countersunk if desirable.
The cords c are passed over the pulleys 6 and attached to the blind-laths fin the
usual manner.
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 improvements in pulley-fittings for Venetian-blinds, substantially as
described, and as illustrated.
2. In pulley-fittings for Venetian-blinds, the use of slotted plates having
depending supporting-brackets carrying the spindles upon which the pulleys
revolve, substantially as and for the purpose described, and as illustrated by the
accompanying drawings.
Dated this 7th day of December 1894.
