PROVISIONAL SPECIFICATION.
Improvements in Blinds for Shop Windows and the like.
I, WILLIAM FRANCIS SMITH HOLT, of Upper Croft Works, Bowling Back Lane,
Bradford in the County of York, Blind and Shutter Maker, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in outside blind's for shop windows and
5 the like, and its object is to cover the windows and exclude. the light in a more
✓ ready and convenient manner than by employing either the common revolving
shutter or by hanging detachable blinds or sheets outside the windows.
The said improvements consist of the arrangement hereinafter described in which
the blind is mounted upon a roller preferably fixed above the window and operated
0 by means of springs, weights or other means adapted to hold the blind under tension
so as to keep it straight and even.
To carry out my invention I preferably employ a spring roller, upon which to
inount the blind, formed of metal and provided with an internal spring arranged
to place considerable tension upon the blind when it is down and sufficiently elastic
5 to raise or draw it to the top. A comparatively stout lath or rib is fixed to the
bottom of the blind by which it is held straight at the bottom, and secured to the
window frame in any suitable manner to keep such blind down when desired.
The edges of the blind and ends of said lath work in grooves formed in the sides
of the window frame and metallic caps are fitted on the ends of said laths to
20 protect them and the blind.
Horizontal ribs may be attached to the blind at intervals having 'their ends working
in said side grooves and protected by metallic caps.
To keep the said metallic caps in the groove down the sides of the window frame
they may be provided with tee or othor suitably shaped ends to engage, the over-
25 hanging edge or edges of said grooves, and clips may be secured to the edge of
the blind having similar shaped ends to hold the sides of the blinds in the grooves.
Notches or projections may be formed in the said grooves adapted to engage the
bottom lath and hold said blind in any intermediate position.

COMPLETE SPECIFICATION..
Improvements in Blinds for Shop Windows and the like.
I, WILLIAM FRANCIS SMITH HOLT, of Upper Croft, Works, Bowling Back Lane,
35 Bradford in the County of York, Blind and Shutter 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 :-
This invention relates to improvements in outside blinds for shop windows and the
-like, and its object is to enable such blinds to work evenly without creases or wrinkles.
0 and thus provide a more ready and compact covering for the windows than..either
detachable blinds or revolving shutters.
The said improvements consist of the arrangements hereinafter described adapted
to enable the blinds to be smoothly and evenly operated without creases or wrinkles,
such blinds being mounted in the usual manner upon rollers preferably fixed above
5 the windows and operated. by-springs,-weights.or..other means..adapted to hold the
blinds under tension..

page_text: In order to fully describe my invention reference is made to the accompanying
sheet of drawings forming a part of this specification in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1, represents an elevation of a shop window with the cornice removed and
in which the outside blinds are provided with my improvements.
Figure 2. is a horizontal section taken diametrically across the spring rollers.
Figure 3, is a similar section through the blinis..
Figure 4, is a vertical side section. And Figure 5, is a view of a detail herein-
after referred to.
One of the blinds A in figure 1. is represented drawn down over the window and
the other A is raised.. Such blinds are mounted upon rollers B and B preferably
provided with internal springs fitted in the ordinary way to raise the blinds and keep
them under tension when drawn down. Grooves Care formed down each side of the
window frame each having a projecting metal lip D projecting partly across and
firmly secured to the frame. The laths E at the bottom of the blinds are provided
with metal caps F and the ends of such caps are formed shaped to fit the
grooves C and by engaging the lips D confine the caps or ends of the lath within
the grooves and also tend to maintain the lath horizontal thus keeping the blinds straight
and smooth. Notches G are formed down the edge of each of the lips D in any
of which the ends of the caps F may be allowed to catch and so hold the blind in
that position until released therefrom.
In case when two windows have only a thin frame between them it is necessary to
arrange the rollers closely together. For this purpose I employ a thin bracket J
(Figure 2) between them having a square hole to receive the square end K of the
spring arbor L. to hold such arbor stationary and the roller B' is arranged to revolve
upon the round end M of such arbor. In this manner the rollers may be arranged
to almost meet it only being necessary to leave space between them for the thin
.bracket J. Three or more rollers may be arranged in this manner.
Horizontal ribs may be attached to the blind at intervals having metal caps
with shaped ends to engage the lips D. Or T or L shaped clips may be secured
to the edges of the blinds at intervals to engage said grooves. When T shaped clips
similar to that represented in figure are employed it is necessary to modify the
shape of the grooves C to receive them.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood
that I do not broadly claim the use of outside blinds for windows, but I declare what
I claim is:
---
:3
1. The combination with outside window blinds, of grooves in the framework or other
convenient part adapted to receive and confine the ends of the bottom lath of the
blind within such grooves,.substantially as herein shown and described and illustrated
in the accompanying drawings.
2. The combination with outside window blinds, of grooves in the framework or
other convenient part to receive the bottom lath of the blind and provided with
notches or their equivalent to engage said lath and hold the blind partly down, sub-
stantially as herein shown and described and illustrated..
3. The combination with outside window blinds of clips secured to the edges
of the blinds or the "ends of lateral ribs and adapted to engage grooves in the frame-
work and confine the edges of the blind within said grooves, substantially as herein
shown and described.
