Improvements in Blinds and in the Fittings thereto.
I CHARLES SAVAGE of 6 Great Hampton Street Birmingham in the County of
Warwick Manufacturer do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention has for its object improvements in blinds and in the fitting thereto
and which has more especial reference to venetian blinds. Blinds as at present
constructed offer considerable obstruction to the light at the upper part of the
windows and in the case of the use of stained glass this is particularly objectionable
as the effect and use is greatly reduced. Now my invention obviates in a great
measure these objections and enables me to obtain the fuller effect of the window
opening and of any ornamental glass with increased blind efficiency that is to say I
am able to make a wider use of the blind while at the same time I remove the
objections thereto.
In order that my invention may be clearly understood and more easily carried into
practical effect I have appended hereunto three double sized sheets of drawings upon
which I have illustrated my blind with the various parts connected therewith and
from which any person will be able to extend the application of the invention to
other varying conditions and circumstances without departing from the principle
thereof.
On sheet 1.
Figure 1 is an interior elevation of a window having one of my improved blinds
the whole of the blind being shewn partially lowered from the top and the blind also
partially down.
Figure 2 is a vertical section through the same figure on line 1-2.
Figure 3 is a similar section to Figure 2 shewing a modification in the means for
receiving the blind when fully let down.
Figure 4 is a similar section through the sill portion of a window shewing a further
modification for receiving the blind when fully let down.
Figure 5 is another section similar to Figure 4 shewing a further modification in
means for the same purpose.
On sheet 2 the following enlarged details are shewn :-
:-
Figure 6 is a view of the end a² of the top rail a' of the blind A.
Figure 7 is a similar view of the end 6 of the top supporting rail 63 which is fixed
to the window frame B.
Figure 8 is a view of the meeting rails of the sashes E and F shewing the
bracket D for preventing the blind from being caught by the ledge formed by the
upper rail of the lower sash E.
Figure 9 is a vertical section through the meeting rails of the upper and lower
sash shewing the modifications R of the bracket D.
Figure 10 is a similar vertical section shewing a further modification S of the
bracket D.
Figure 11 is a section through the brackets D R and S on line 3-4.
Figure 12 is a broken off view of a piece of the box shewn in Fig. 4 showing the
plate gl for the purpose of hooking the box on in the required position.
On sheet 3 are the following
Figure 13 is a side elevation of the bracket H shewn in Figures 1 and 2 for
supporting the blind when fully let down.
Figure 14 is a front elevation of same shewing it of ornamental design.
Figure 15 is a side elevation of the bracket J shewn in Figure 5.

page_text: Figure 16 is a section through the venetian blind in which two cross tapes are
used instead of one.
Figure 17 is an elevation of the underside of the bottom rail of the blind showing
metal rose for covering the end knot of the cord.
Figure 18 is a section through the same rail shewing the metal rose in section.
In carrying my invention into effect I provide the Blind A as shewn at Figure 1
with the top rail a² which is provided with the metal ends a Figure 6 having the
eyelet hole a and secured by any number of screws or in any suitable manner.
Within the eyelet hole or in any other manner I secure the cords k¹ and k³ at
each end respectively which cord is carried up to the top supporting rail 6¹ which
is fixed to the window frame B and is provided with the metal box pulley 62 over
which the cord passes the molded and grooved strip ³ being provided to cover
the cord k¹ one which passes along the supporting rail the box pulley at the other end
being provided with two pullies one for the cord k¹ and the other for the cord k².
These pullies may be varied in shape and material but they are arranged in the case
under illustration so as to bring the cords as near the end of the rail as possible. In
cases however the blinds are fixed outside the window frame this would not be
essential and the ordinary pullies might be used. The top rail a² of the blind is
also provided with the ordinary pullies by which the blind A may be raised or
lowered by means of the cord L independently of the arrangement previously
described which by means of the cord k enables the blind to be raised as a whole or
lowered as a whole until it rests in the brackets H which are provided to receive
it. In this way the blind may be left in the position shewn in Figures 1 and 2
which allows free ventilation when the window is opened at the top or it may be
lowered to form a curtain to the window leaving the top part of the window free
from obstruction or it may be allowed to fall entirely and rest in the brackets 'H as
above described which would leave the whole of the window free from any
obstruction whatever. The ordinary portion of the blind may be operated from either
side the cords being secured by Youngs holdfast cleat hooks or ordinary holdfasts P
as may be desired. The brackets H may be of any suitable metal or material and
are provided with the dove tail h¹ figure 13 which would slide into the socket h
which would in turn be fixed on any convenient position or the brackets may be made
to screw on or be otherwise fixed and they may be ornamented to any extent as
illustrated by Figure 14.
Instead of supporting the blind when fully down by brackets the recess M may be
formed in the window board to receive it as shewn by Figure 3 the recess being
covered by the flap hinged window board m¹ or in cases where the structional con-
ditions will not allow of it a box G may be provided as shewn in Figure 4 either
with an hinged flap or without and formed of either wood, cardboard, paper-mache,
wicker, cane metal or any other material and may be fixed or removable by means of
the slotted plate g' as shewn by Figure 12 or fixed in any other suitable way.
this case the guide J as shewn by Figure 15 would be provided to prevent the blind
from ledging on the window board this guide being either fixed or hooked on similar
to the bracket H and may be of any material or of any design.
In
The recess to receive the blind may also be provided in the floor as shewn by N
Figure 5 and provided with the flap n¹ and in case of upper rooms this may be cased
into the lower room in any ornamental way. may also carry the blind "cords
through the floor and attach a light weight to the end so as to prevent them when
loose from lying about and becoming entangled. I may hang my blind so as to fall
into the recess of present bottom shutter boxes.
To prevent the blind from becoming ledged upon the upper rail F of the lower
sash FI provide the guide D as shewn in Figure 8 of which any number may be
provided across the width of the window although for all ordinary purposes two would
be sufficient and these I ornament to any extent so long as the section is somewhat
like Figure 11 in which the two circular surfaces d' d form a rounded surface to
receive the blind and which would not tend to fray or damage the material or tape.

page_text: I do not confine myself to the particular shape of these guides Figures 9 and 10.
R and S shew modifications, the centre stiffening pieces being shewn in the case
of S all of which are equally applicable for use in the case of spring roller linen,
print, holland, or other class of blind.
To prevent the cord from slipping through the bottom rail a of the blinds and
become entangled I provide the metal or other suitable rose T with a swell at centre
to cover the knot of the cord and thus I may fasten on in any suitable way but
preferably with the grip pins t¹ this rose being equally applicable to all classes of
venetian blinds.
In addition to the ordinary cross tape v Figure 16 under each lath for their sup-
port I may provide a second cross tape v² above each lath so as to keep the laths from
being shaken out of place.
I may apply my double top rails and blind lowering arrangement in combination
with any existing patent.
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 :-
First. The improvements in blinds by which they may be bodily lowered from the
top of the window and concentrated in any other desired position substantially as
herein set forth and shewn upon the drawings.
Second. In blinds and in the fittings thereof the guide brackets D, R or S or their
equivalents substantially as and for the purpose herein set forth and shewn upon the
drawings.
Third. In venetian blinds & in the fittings thereof the rose T substantially as and
for the purposes herein set forth and shewn upon the drawings.
Fourth. In venetian blinds and in the fittings thereof the additional cross tape v²
substantially as herein set forth and shewn upon the drawings.
Fifth. The Improvements in blinds and in the fittings thereof substantially as and
for the purpose herein set forth and shewn upon the accompany three sheets of
drawings.
