Improvements in Adjustable Window Blind Supports.
We, ULYSSES SIMPSON PARISH, Lawyer, and FLAVEL AARON RUDOLPH, Lawyer.
both residing at Carmi, in the County of White and State of Illinois, 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:
The object of the invention is to provide a new and improved window blind
holder, arranged to permit of conveniently and quickly moving the ordinary spring
roller carrying the blind up or down in the window, to permit of unscreening the
upper portion of the window to admit light and air, while the lower portion of the
window is screened by the blind.
The invention consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure 1 is a front elevation of the improvement as applied;
Figure 2 is a transverse section of the same;
Figure 3 is an enlarged side elevation of the rod and the blind frame support;
Figure 4 is a front elevation of the upper end of the rod; ..
Figure 5 is a plan view of the support;
Figure 6 is a front elevation of the clamping device for the support on the rod;
and
Figure 7 is an inverted perspective view of the roller frame.
.As illustrated in the drawings, the window casing A contains the usual upper
and lower sashes B B¹, and on the top cross-bar of the said frame and near the
middle thereof, secured the upper bracket end C¹ of a vertically disposed rod. C,
extending downward in front of the upper sash and part of the lower sash, as
plainly indicated in the drawings. On this rod C is mounted to slide the transversely
extending plate D formed with a downward extension D¹ forming a support for the
frame E in which the spring roller F is journaled, the said roller carrying the
usual blind G. The frame E is preferably made in two parts, E1 E2, of channel
iron fitted to slide one on the other, with the ends E3 E4, formed to receive the
trunnions of the roller F (see Figure 7). Bolts E5 serve to fasten the parts E¹
and E2 together after the same have been adjusted lengthwise to fit the length of
the spring roller F. The bolts E extend through slots in the said parts E¹ E²,
and also engage transversely extending slots D³ formed in the plate D, so that the
support and frame are rigidly secured together after proper adjustment is made of
the frame relative to the length of the blind roller F, and the plate D is laterally
adjusted relative to the position of the depending rod C.
From the plate D¹ project bearing ears D* in which are pivoted the trunnions or
studs of a clamping lever H. This lever has an opening H¹ through which the rod

page_text: projects and a spring H² serves to lock the lever to the rod and consequently the
The free end of the
blind frame E, in the desired position in front of the window.
lever H is formed with a bent handle H³, which is connected with one end of an
upwardly extending cord J passing around a pulley J journaled in a bracket end C₁
of the rod C. The downwardly extending end of the cord Jis adapted to be taken 5
hold of by the operator so as to exert a pull on the cord to impart an upward
swinging motion to the free end of the lever H³, so as to free its other end from
the rod C. When this is done, a further pull on the cord J will cause the entire
support, frame E and roller F with the blind G, to be moved upward; and when
it is desired to lower the devices referred to, the operator by slightly slacking the 1
cord J, can cause the parts to descend until the desired position is reached. When
this is done, the operator releases the free end of the cord J, so that the spring
instantly returns the lever to its clamping position, and securely locks the support
in place, to hold the frame E and curtain roller F in the desired position.
It is understood that the projection D5 limits the upward swinging motion of the 1
free end of the lever when a pull is exerted on the cord J, so that its other end is
out of engagement with the rod at the time its free end strikes and rests against
the said projection D³
It will be seen that the device is very simple and durable in construction, can be
easily manipulated, and is not liable to get out of order. In order to prevent the
sleeve D¹ from accidentally becoming detached from the rod C, we provide the
lower end thereof with a knob C2 as shown in the drawings. If desired the rod
may be made polygonal in cross section and many other changes may be also made
without departing from the spirit of the invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination with the rod depending from the window casing, of the
support longitudinally adjustable thereon and provided with a horizontal plate
formed with slots, an adjustable frame for the blind roller, and fastening devices.
holding said frame in adjusted position, and adjustably connecting said frame with
said horizontal place, as and for the purpose set forth.
2. The combination with the rod attached to the window casing, and the support
adjustable thereon, of the blind frame made in two angular and adjustable sections
fitted to slide one upon the other and provided with coincident slots, and fastening
devices in said slots and fastening said sections in adjusted position, the said
devices adjustably attaching said blind frame to said support substantially as
shown and described.
3. The combination with the rod depending from the top of the window casing,
of the support adjustable thereon and provided with the horizontal plate formed.
with transverse slots, a frame for the blind roller, said frame being formed in
sections fitted to slide one upon the other and provided with coincident slots, and
bolts working in the slots of the horizontal place and the frame sections, whereby
the sections are adjusted relative to their distance from the rod and held adjusted
to fit various sizes of blind rollers, as and for the purpose set forth.
4. The combination with the rod depending from the window casing, of the
support, comprising a vertical plate and a horizontally extending plate carried
thereby, a clamping lever journaled to the vertical plate, and having an aperture
at one end through which the rod projects, and a spring serving to lock the lever
to the rod, a frame consisting of sections fitted to slide one upon the other, and.
attaching devices adjustably connecting said sections together and adjustably
connecting said frame with said horizontal plate, substantially as shown and
described.
5. In a blind hanger, the combination of a rod having one end attached to the
top of the window casing and having its other end free; a support longitudinally
adjustable on said rod; a frame for the blind roller, said frame being adjustable

page_text: for different lengths of rollers, bolts passing through said frame and holding the
same adjusted, the said bolts being adjustably connected to said support, a lever
journaled to said support having an opening in one end through which the rod
projects, a spring acting on said lever to throw it into engagement with the rod,
a bracket attached to the upper end of said rod, a pulley journaled in said
bracket, and an operating cord connected to the free end of said lever and passed
around said pulley, as-and for the purpose set forth.
6. A blind hanger, comprising a rod attached to the center of the window
casing and depending therefrom, a support consisting of a vertical and horizontal
plate, mounted to slide on said rod, a clamping lever journaled to said vertical
plate, one of the ends of said lever being provided with an aperture through which
the rod projects, a coiled spring by which said lever is thrown into engagement
with said rod, a pulley journaled on the upper end of said rod, a cord attached to
the free end of said lever and passing around said pulley, whereby said free end of
said lever is elevated, a lug carried by said vertical plate, and by which the upward
movement of said lever is limited, and a frame formed in two channeled sections
fitted to slide one upon the other and carrying the blind roller, said frame being
connected with said horizontal plate, being adjustable to and from said rod, as and
for the purpose set forth.
