'IMPROVEMENTS IN BLINDS OR SCREENS FOR WINDOWS AND OTHER OPENINGS"
This invention relates to improvements upon and additions to the well known
expanding wood blinds and has for its object the strengthening and improving the
appearance of the same. The said blinds as heretofore constructed consisted
simply of a number of thin and narrow strips or slats of wood or other like
material crossing eachother and pinned together at the intersections on the
principle of lazy-tongs levers the said combined strips being secured at each side
to upright supports or strengthening pieces whilst the top and bottom ends of each
of the strips were left free or without any protection rendering the blind unsightly
and unsteady when expanded and liable to be damaged or broken when dusted.
Now according to my invention I cover and protect the tops and bottoms of the
series of expanding slats of wood by placing over or under the same a longitudinally
grooved rail extending from side to side of the blind and secured at the opposite
ends by pins or otherwise to the tops and bottoms respectively of the upright end
supports, the said supports combined with the longitudinally grooved rails forming
a firm and steady frame within which is enclosed the expanding portion of the
blind. The upper and lower ends of the expanding crossed slats or strips fit inside
the grooves or channels in the longitudinal rails of the blind and receive therefrom
a firm lateral support and protection from injury whilst the general appearance of
the blind is considerably improved. The said grooved rails before being attached
to the blind will of course require to be cut to the proper length to suit the width
of the window or opening to which the improved blind is to be applied

"IMPROVEMENTS IN BLINDS OR SCREENS FOR WINDOWS AND OTHER OPENINGS
"
My said Invention relates to improvements upon and additions to expanding
wood blinds of ordinary construction and has for its object the strengthening of
such blinds and improving them both as regards their use and appearance. The
said blinds as heretofore constructed consisted simply of a number of thin and
narrow strips of wood or other like material crossing each other and pinned
together at the intersections on the principle of Lazy-tongs levers the said series
of combined strips being permanently secured at each side to upright supports or
strengthening pieces (to be secured to each side of the window or other opening)
whilst the top and bottom ends of the several strips were left free or without any
protection rendering the blind unsightly and unsteady when expanded and liable
to be damaged or broken when being dusted.
Now according to my invention I cover and protect the tops and bottoms of the
said series of expanding strips of wood by placing over and under the same a
longitudinally grooved rail of wood metal or other suitable material (either plain
or ornamented in any suitable manner) extending from side to side of the blind
and secured at the opposite ends by pins or other suitable fastenings to tenons
formed on the ends of the side supports of the blind, the longitudinally grooved
rails combined with the side supports forming guides and acting as a firm and
steady frame within which is enclosed the angularly.disposed cross strips forming
the expanding portion of the blind. The upper and lower ends of the expanding
crossed strips fit inside the grooves or channels in the longitudinal rails of the
blind and derive therefrom a firm lateral support and protection from injury whilst
the general appearance of the blind is considerably improved. The said grooved
rails before being attached to the two side uprights or supports will be cut to the
proper length to suit the width of the window or opening to which the improved
blind is to be applied or they may obviously be made expanding or Telescopic.
And in order that my said invention may be fully understood. I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the explanatory sheet of drawings hereunto annexed the same letters of
reference indicating corresponding parts in all the figures.
Figure 1 of the drawings is a face view of my said improved blind complete and
ready for fixing. Figure 2 is a similar view of the same blind showing the mode
of applying the grooved top and bottom rails and figure 3 is an edge view of one
of the side uprights or supports and a cross section of the grooved rails fitting
thereon.
a a are the usual narrow strips of wood pinned together at their intersecting or
crossing parts by pins round which they are free to play when the blind is being
expanded or compressed to the desired dimensions and b b are the two usual side
uprights or supports to which the crossed strips a a are permanently secured by
pins cement or otherwise all of which is well known cclare the two longitudinal
grooved rails acting to guide and support the strips of wood aa and secured at
their ends by pins or any well known mode of fastening to the uprights b b said
uprights being by preference formed with tenons b¹ 61 at their upper and lower
end. The groove in each rail co¹ is adjusted over the free ends of the narrow
strips a a and over the tenons 6¹ so as to effectually enclose and protect the strips

page_text: at the top and bottom. The rails c c when made of wood may have the groove
cut therein by means of a carpenters "Plough" as will be readily understood and
when made of metal they may either be cast with the groove therein or may be
made of sheet metal folded or doubled longitudinally so as to leave an inner
groove or space for the reception of the ends of the crossed strips and tenons.
The most convenient and simple mode of applying the grooved rails is to first
close the lattice work (as shown in figure 2) lay it on a flat surface or table and
then slide on the two grooved rails c c' over the tenons 61 6¹ and ends of the strips a
baving previously measured the width of the window or other opening and cut the
grooved rails to a corresponding length The rails are then nailed or otherwise
fixed at one end to one of the uprights b and the lattice is expanded by drawing
the other upright along the grooves to the opposite ends of the rails where it is also
permanently secured.
The improved. blind may be secured to the sash or to the frame of the window
or other opening by pins or screws passing through slots or holes d made in the
uprights b or by any other convenient mode of fixing.
Having now described and particularly ascertained the nature of my said
invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the invention secured to me by the hereinbefore in part
recited Letters Patent is:―
The combination of parts consisting of an expanding wood blind or screen and
longitudinal grooved or channelled protective guiding and strengthening rails
attached to side supports and receiving within suitable grooves or channels the
ends of the crossed strips forming the expanding portion of the blind constructed
substantially as herein described and illustrated in the annexed drawings.
In witness whereof I the said Henry Arthur Goodall have hereunto set my
hand and seal this Thirteenth day of May in the year of our Lord one thousand
eight hundred and eighty four.
