Improvements in Window Blind Brackets.
I, EDWIN JOSHUA CLAYTON, Mechanic, of 3954, Wyalusing Avenue, 758, De Kalb,
Street, City of Philadelphia, in the County of Philadelphia, State of Pennsylvania,
one of the United States of America, 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 window blind brackets and has for its object to provide a
simple, cheap and efficient device of the character referred to, designed to sustain a
window blind roller in operative position in a window frame and adapted to be placed
in position and held by reason of its own resiliency and without the aid of auxiliary
fasteners.
The improved bracket is also adapted to be removed from its position on the
window frame with ease and rapidity and without the necessity of extracting auxiliary
securing devices, thus obviating the marring or mutilation of the window frame.
The device is also applicable to window frames of various sizes and of varying distances
between the parting bead and window- stops.
Other objects and advantages of the invention will appear in the course of the
subjoined description.
The invention consists in certain novel features and details of construction
and arrangement of parts hereinafter fully described and illustrated in the
drawings.
In the accompanying drawings:
Figure 1 is a view in elevation of one of the window brackets showing the same
applied to a portion of the window frame between the parting bead and one of the
window stops.
Figure 2 is a similar view showing the opposing member of the bracket.
Figure 3 is a detail perspective view of one of the brackets.
Figure 4 is a similar view of the other member of the bracket.
Figure 5 is a detail horizontal section taken through a pulley stile, parting
bead and one of the stops of sash beads, said section extending also through the
bracket.
Similar numerals of reference designate corresponding parts in the several figures
of the drawings.
The improved brackets, contemplated in this invention, are each constructed in
one piece from a wire blank. The brackets are, of course, made in sets or pairs, each
set or pair comprising two members, one member being provided with an eye 1 and
the other member with a slot or notch 2, the eye 1 being adapted to receive the pin

page_text: or trunnion at one end of a curtain shade roller, and the slot or notch being adapted to
receive the flattened spindle or trunnion at the opposite end of the roller in a
manner readily understood by those familiar with the art to which this invention
appertains.
In constructing one of the brackets a piece of spring wire, preferably steel wire, of
the requisite length and gage, is folded upon itself at an approximately central point
to form an open loop 3, comprising or bounding and defining the slot or notch 1 for
the reception of the flattened spindle of the roller. When in position for use this
open loop occupies a substantially vertical position. The terminals of the wire are
bent substantially at right angles at the points 4 and extended in substantially
parallel relation towards the pulley stile, indicated at 5, for a distance of about three-
eighths of an inch, more or less, after which the terminals are again bent.at the
points 6 and extended in a plane parallel to the loop 3.
The terminals are now spread apart or made divergent to form upwardly diverging
spring arms 7. After extending upward a suitable distance the spring arms are
re-curved in reverse directions, each arm being curved at the point 8 inward, after
which each arm is reversely curved or given a compound bend, as shown at 9, and
then extended in a straight oblique, so as to bring the extremity of the terminal into
an approximately horizontal position and so as to extend laterally and engage
positively with the parting, bead 10 or sash bead or stop 11, as the case may be. The
spring arms cross each other at the point 12 and extend thence in opposite directions
and their extremities may be blunt or tapered or pointed, as indicated at 13, so that
they will partially embed themselves in the parting bead and sash bead and prevent the
displacement of the bracket.
By means of the construction described, the more weight or downward pull on the
roller, and consequently on the bracket, the greater the force with which the
extremities of the spring arms will be forced into engagement with the parting bead
and sash bead, thus rendering it impossible for the bracket to be displaced in a
downward direction, or that direction in which all the strain comes. An important
feature of the invention resides in the fact that the ends of the arms or terminals lap
over and bear against the inner side of the divergent portions of the arms so that
the said divergent portions rest between the end portions of the arms and the pulley
stile. This prevents the extremities of the arms from engaging behind the parting
bead or sash bead and prying the latter loose or away from the pulley stile.
Another important feature is that each member of the bracket bears at four
different points against the beads or stops thus insuring the positive engagement of
the device with the window frame.
The opposing member of the bracket is constructed precisely the same as the above
described with the single exception that instead of the open loop 3 the wire is bent
at a central point to form a coil or eye for the reception of the round pin or trunnion.
at one end of the shade roller. The portions of the wire above the eye are brought
closely together as shown at 15. The device is extremely simple in construction, is
made of inexpensive material, may be manufactured with great rapidity, may be sold
at an extremely low cost, is applicable to windows of different sizes, and may be
placed in position and removed therefrom by anyone, as it does not require the
services of an experienced workman. In addition to these advantages the improved
bracket will not mar or disfigure the window frame, and requires no auxiliary fastening
devices for securing the same in place.
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. A shade roller bracket, consisting of wire bent upon itself at an intermediate
point to form a bearing for one end of a roller the terminals diverging therefrom and
being then curved inward, crossed and reversely curved and finally extended in
substantially straight lines and projected, substantially as and for the purpose
specified.

on a window frame, said arms being crossed and extended so that their extremities
project in opposite directions to form other bearing points.
