Improvements in Sun-blinds for Shading and Regulating the
Admission of Light to Conservatories and Glass Houses, the
said Blinds being also applicable for Domestic and other
Purposes.
I ELIJAH ASHWORTH of the Moss Brook Works, Collyhurst, Manchester,
in the County of Lancaster, Machine Maker, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to sun blinds for shading and regulating the admission
of light to conservatories, glass houses and other buildings &c. the said blinds
being also applicable for domestic and other purposes.
The improved blinds constituting my invention are made from a combination of
woven tapes and laths of wood, prepared paper or other substance or material
and are intended to supersede the woven blinds and metal linked laths at present
in use.
According to my invention the tapes to carry the laths consist of two tapes
woven or sewn or otherwise secured face to face and so as to present spaces to
receive the laths. The back or lower tape may be made wider or stronger than
the other tape. The laths or slips of wood are pushed through the spaces left
between the tapes, the proper intervals between the laths being provided for.
A salient advantage arising from the manufacture and use of my improved
blind is that a defective lath can at any time be removed and replaced, or the laths
can be removed for painting or cleaning while their prime cost is less than that of
the sun blinds at present in use. To render the tape more durable I prefer to
treat or cover the tape or the material from which it is woven with a suitable
dressing which will better enable it to resist decay and deleterious atmospheric
influences. Each lath may be lightly tacked to the tape so as to prevent displace-
ment, or the laths might be checked on one or both edges at the points where they
engage with or are embraced by the tapes.
When applied to a conservatory for example, my improved sun blind is mounted
in the usual manner above the glass and has a diffusing and tempering effect upon
the transmitted light which is highly favourable to the growth of orchids for
example.
Although specially suited for the indicated uses my improved sunblind might
also be employed for domestic and other purposes.

COMPLETE SPECIFICATION.
Improvements in Sun-blinds for Shading and Regulating the
Admission of Light to Conservatories and Glass Houses, the
isald Blinds being also applicable for Domestic and other
Purposes.
I ELIJAH ASHWORTH of the Moss, Brook Works, Collyhurst, Manchester,
in the County of Lancaster, Machine Maker, 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 and accompanying
drawings:-
My said invention relates to sun blinds for shading and regulating the admission
of light to conservatories public buildings or private dwelling houses, vehicles &c.
and for protecting trees and plants from extremes of temperature.
The improved blinds constituting my invention are made from a combination of
woven tapes, and laths of wood, prepared paper or other substance or material and
are intended to supersede the woven blinds and metal linked laths at present
in use.
To render my invention perfectly clear I have annexed hereto a sheet of
drawings illustrating the construction of my improved sun blind.
Fig. 1 is a view of three laths supported by the improved tapes..
Fig. 2 is an edge view of the sewn or prepared tapes which receive the laths.
Fig. 3 is a plan of Fig. 2.
Fig. 4 illustrates a modified method of forming the tape by weaving.
According to my invention the tapes to carry the laths consists of two tapes a
and 6 sewn or otherwise secured face to face the tape a being so applied as to
present spaces c (as indicated in Fig. 2) to receive the laths d. The back or
lower tape b is or may be made wider or stronger than the other tape a and this
stronger tape is preferably arranged to lie in a straight line as shown in Fig. 2
so as to take the bulk of the strain. The laths or slips d of wood, or other
suitable material are pushed through the spaces c left between the tapes a and b
the proper
intervals e between the laths d being provided for. The improved
blind may be made of any width and any suitable number of supporting tapes
may be used.
A salient advantage arising from the manufacture and use of my
improved blind is that a defective lath can at any time be removed and replaced,
or the laths can be removed for painting or cleaning. The prime cost of my
improved blind is less than that of the sun blinds at present in use. To render
the tapes more durable I prefer to treat or cover them or the material from which
they are made with a suitable dressing which will better enable them to resist
decay and deleterious atmospheric influences. Each lath may be lightly tacked
to the tape by tacks g so as to prevent displacement, or the laths might as shown at
Fig. 34, be checked on one or both edges at the points where they engage with or
are embraced by the tapes.
Instead of preparing the tapes so that one of them shall lie in a straight line as
shown in Fig. 2 I might simply weave a tape with a series of open loops faɛ
shown in Fig. 4.
When the laths d are thrust into these loops, as shown on the right hand side
of Fig. 4, the connecting portions e lie midway in the thickness of the lath instead
of to one side as in Fig. 2.
When the aforesaid tapes are woven I use a suitable loom for the purpose and
would employ two warps and two shuttles. When weaving the form illustrated
by Fig. 4 the operation is simple. When weaving the connecting pieces between
the spaces f, the warps are brought together and only one shuttle works to weave

page_text: the warps into one web. But when the spaces are being woven, the two warps-
are separated and one shuttle weaves the lower and the other the upper thickness.
on each side of the space.
When applied to a conservatory for example, my improved sun blind is mounted
and rolled and unrolled in the usual manner above the glass and has a diffusing
and tempering effect upon the transmitted light which is highly favourable to the
growth of orchids for example.
I do not however limit the uses of my improved blind; for example it may be-
used as an ordinary domestic window blind, or for shading the interior of public
or private vehicles, or as a covering to protect the outside passengers of tram cars,.
or to protect trees and plante.
In all positions my improved flexible blind can be easily rolled up or let down.
My improved blind is simple and strong in construction, can be easily and cheaply
produced and repaired and cannot readily get out of order.
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 a sun or other blind consisting of laths or slats carried by tapes, forining
the said supporting tapes of two strips sewn or otherwise secured face to face and
presenting spaces at intervals to receive the laths or slats, substantially as herein--
before described and shown.
2. In a sun or other blind consisting of laths or slats carried by tapes, forming
the said supporting tapes of two strips sewn or otherwise secured face to face and
presenting spaces at intervals to receive the laths or slats, one of the said tapes
being made wider or stronger than the other and extending in a straight line so as
to take the bulk of the strain, substantially as described and shown.
3. In a sun or other blind consisting of laths or slats carried by tapes, forming
or weaving the said tapes with a series of open loops or spaces to receive the laths
or slats, substantially as described and as shown in Fig. 4 of the drawings.
4. The improved blind tapes woven or otherwise manufactured in the manner
and in the respective forms hereinbefore set forth.
