PROVISIONAL SPECIFICATION.
Improvements in Blinds and Shutters.
I, HARVEY MURDOCK of 11, Montgomery Place, Brooklyn, in the County of
Kings and State of New York, United States of America, Builder, do hereby
declare the nature of this invention to be as follows:-
My invention relates to improvements in sliding window blinds and shutters
and the object of my invention is to produce a simple form of sliding blind which
may be cheaply made and easily applied to a window, which may be easily operated,
which if desired may be pushed up out of the way and also out of sight, and which
inay be held at any desired height.
The blind embodying my invention is especially adapted for use in windows of
dwelling houses, but it may be used in any kind of window or as a shutter for a
door or other opening in a building.
The window or door casing has vertical grooves on its inner sides and these
grooves at their upper ends enter a box at the top of the casing and which has a
guard next the grooves, which guard is curved slightly inward so that the blind
may move readily over it. The groove is widened at the point where it enters the
This blind
box and at the ends of the box are pulleys over which the blind runs.
is made up of a series of slats the ends of which project into the grooves and are
jointed together at the ends by short links in the manner of a pitch chain. The
blind may be easily pushed up and down in the grooves and when it is raised the
slats fold alternately backward and forward so as to lie flatwise in a compact pile
in the rear portion of the box. The weight of the folded slats will have a tendency
to hold the other slats in position, but as a further protection against the acci-
dental moving of the blind the lower slat is provided at its ends with springs
which press against the back walls of the grooves.
From the foregoing description it will be seen that the blind is very simple in
construction and that it may be easily operated. For ordinary window purposes
the blind would be preferably constructed of wood, but if desired it may be made
of metal and will serve as a shutter.

Improvements in Blinds and Shutters.
1 HARVEY MURDOCK of 11 Montgomery Place, Brooklyn, in the County of
Kings and State of New York, United States of America, Builder, 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 :-
My invention relates to improvements in sliding window blinds and shutters, and
the object of my invention is to produce a simple form of sliding blind which may
be cheaply made and easily applied to a window, which may be easily operated,
and which if desired may be pushed up out of the way and also out of sight,
and which may be held at any desired height.
Reference is to be had to the accompanying drawings forming a part of this

page_text: neation, in which similar ngures of reference indicate corresponding parts im
all the views.
Figure 1 is a front sectional view on the line 1-1 in Figure 2, of the blind and
attachment as applied to a window;
Figure 2 is a vertical section on the line 2-2 in Figure 1 ;
Figure 3 is a broken front elevation of the blind; and
Figure 4 is a broken end view of the same.
The blind embodying my invention is especially adapted for use in windows of
dwelling houses, but it may be used in any kind of window, or as a shutter for a
door or other opening in a building. In the drawings, I have shown it applied to a
window, the window casing 10, having vertical grooves 11, on its inner sides, and
these grooves at their upper ends lead into a box 12, which is secured to the top
of the window casing, and which has a guard 13, next the grooves 11, which
guard is curved slightly inward so that the blind may move readily over it.
The groove 11 is widened at the point where it enters the box 12, as shown at
14, and at opposite ends of the box and at a point near the upper terminals of the
grooves, are pulleys 15, over which the blind 16 runs. This blind 16 is made up
of a series of slats 17, the ends of which project into the grooves 11, and the slats
are pivotally connected together at the ends by short links 18. The blind is
provided centrally with a suitable handle 19, by which it may be easily pushed up
and down in the grooves, and when it is raised the slats 17 after passing over the
rollers 15 will fold alternately backward and forward so as to lie flatwise in a
compact pile in the rear portion of the box 12, as shown in Figure 2. The weight
of the folded slats will have a tendency to hold the other slats in position, but as
a further protection against the accidental moving of the blind, the lower slat is
provided at its ends with a leaf spring 20, as shown by dotted lines in Figure 1,
each spring being secured by its middle to the slat and to its free ends pressing
against the back wall of the groove 11.
From the foregoing description it will be seen that the blind is very simple in
construction and that it may be easily operated. For ordinary window purposes
the blind would be preferably constructed of wood, but if desired, it may be made
of metal and will serve as a shutter.
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 combination of the casing, the box secured to the top of the casing and
extending across the same, the box having an opening and a curved guard
extending across it, vertical grooves in the casing and extending into the box, the
grooves being widened at their upper ends, guide rollers pivoted to the ends of
the box, and a blind comprising a series of slats hinged together, held to slide in
the grooves passing over the guide rollers and adapted to fold alternately back-
ward and forward, the one slat upon another within the box, substantially as
described.
2. The combination of the window casing, the box secured at the upper end of
the casing, vertical grooves in the casing and having their upper ends curved
when they enter the box, a curved guard extending across the box and forming
one side of the upper end of the grooves, guide rollers pivoted to the ends of the
box immediately above the guard, and a sliding blind fitted to slide in the grooves
and comprising a series of slats hinged together at the ends and adapted to fold
one upon the other within the box, substantially as described.
Dated this 5th day of January 1908.
