PROVISIONAL SPECIFICATION.
Improvements in or connected with Window Blind Rollers and
Brackets therefor.
I, JOSEPH HARPER KEARTON of 38 Salcott Road, Wandsworth Common in
the County of Surrey, Vocalist, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to provide a simple means whereby window blinds
may be held when raised or lowered to any desired height without the necessity of
securing the blind cord to cleats or other fastenings.
According to this invention I secure to the blind roller in addition to the cord
pulley a second pulley over which is passed an indiarubber or other flexible band
which band passes round a third pulley rotating on a stud secured to the bracket.
The two extra pulleys carrying the flexible band may be either inside or outside
the bracket at either end of the roller, or the flexible band and cord pulleys may
be made in one piece, the band pulley being outside the cord pulley.
The rubber or other band is stretched over the pulleys sufficient tension being
put on the band to hold the blind in any position.
This invention is particularly applicable to railway carriage blinds and blind
rollers worked by a single cord coiled on the cord pulley as by its means cleats,
catches, ratchets, springs, and the like are avoided.

COMPLETE SPECIFICATION.
Improvements in or connected with Window Blind Rollers and
Brackets therefor.
I JOSEPH HARPER KEARTON of 38 Salcott Road Wandsworth Common in the
County of Surrey Vocalist 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 provide a simple means whereby window blinds
may be held when raised or lowered to any desired height without the necessity
of securing the blind cord to cleats or other fastenings.
According to this invention 1 secure to the blind roller in addition to the cord
pulley a second pulley over which is passed an indiarubber or other elastic band
which passes round a third pulley rotating on a stud secured to the bracket.
The two extra pulleys carrying the elastic band may be either inside or outside
the bracket at either end of the roller, or the elastic band and cord pulleys may
be made in one piece the band pulley being outside the cord pulley.
The rubber or other band is stretched over the pulleys, sufficient tension being
put on the band to hold the blind in any position.
This invention is particularly applicable to railway carriage blinds and blind
rollers worked by a single cord coiled on the cord pulley as by its means cleats
catches ratchets springs and the like are avoided.

page_text: And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in which
Fig. 1 represents an elevation of a portion of a window blind fitted with rollers
and brackets constructed according to my invention.
Fig. 2 is section of the same.
The same letters denote the same parts in all the figures.
a is the window blind attached to the roller b which roller has attached thereto
a cord pulley c on which is coiled the blind cord d. Attached to or forming part
of the pulley c is a second pulley e round which passes a band of indiarubber or
other suitable elastic material the said band also passes round a third pulley g
rotating on a suitable pin or stud attached to the bracket i. Sufficient tension
is put on the band to enable the blind a to be held in any desired position.
This invention will be found particularly applicable to the blinds of railway
carriage, omnibus and tramcar windows as it is not liable to get out of order and
the sustaining mechanism may be out of the reach of persons travelling in such
vehicles.
The blind a may be weighted or have a cord attached thereto for lowering
purposes.
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 :-
I. In window blind rollers and brackets therefor the elastic band fas and for
the purpose stated.
II. In window blind rollers and brackets therefor the combination of the
pulleys e and g with an elastic band substantially as and for the purposes stated.
III. The improvements in window blind rollers and brackets therefor substan-
tially as described and shewn by the accompanying drawings.
Dated this 3rd day of February 1893.
