Improvements in Mountings or Supports for Window Blind Rollers,
Curtain Poles, Wall Brackets, and other objects.
I, GEORGE BIEHN, (Merchant), of North Yakima, in the County of Yakima,
and State of Washington, United States of America, do hereby declare the nature
of this invention to be as follows:-
This invention relates to window blind fixtures and has for its object to provide
fixtures which are adapted for ready attachment upon the side or top mouldings
of window casings without the use of wood screws or nails so as to afford reliable
support for the window blind at a desired point of the casing and also enable the
easy removal of the said fixtures without the use of tools. A further object is
to provide a device of the indicated character with novel bracket supports for a
curtain pole which are likewise adapted for attachment or removal without a tool as
occasion may require.
The invention essentially consists in the novel construction and combination
of parts as is hereinafter described.
The improved blind fixture is to be provided in duplicate for the support of
each end of a blind roller upon both sides of a window casing. Each one of a
pair of blind fixtures required to support a blind at a window consists of the
following described parts:-An elongated bracket plate having its side edges
bent inwardly to provide a shallow recess of dovetailed form in cross section. At
one end of the bracket plate a limb is secured by its foot. A clamping bar is
adapted to engage its side edges with the inwardly bent edge portions of the
bracket plate when inserted endwise within the shallow open recess formed for
its reception in said bracket plate. The clamping bar is longitudinally slotted
so as to lighten it and also to permit the free introduction therein of a long adjust-
ing screw which engages with a perforation in the base of the limb and has a
like engagement with a tapped hole in a cross bar at one end of the clamping
bar. The adjusting screw is furnished with a milled head for its convenient
manipulation when the bracket plate is to be secured in place or released. - On
the end of the clamping bar which is opposite from that engaged by the adjusting
screw a limb is formed or secured which is similar to the limb above mentioned
both of said limbs having teeth projected at their upper edges toward the cross
bar of the clamping bar. A bracket arm is fitted to slide upon the bracket plate,
said arm comprising an elongated body having a widened base portion which is
recessed on the side that engages the bracket plate. The recess in the base por-
tion is undercut on the side edges or walls thereof so as to closely embrace the
dovetailed body of the clamping bar when the latter is engaged by the bracket
arm.
A longitudinal slot is centrally formed in the body of the bracket arm of
sufficient length to produce two similar clamping limbs thereon. If the material
from which the bracket arm is formed will afford elasticity to the clamping limbs
mentioned the arm will by the assured clasping engagement of said clamping

page_text: limbs with the bracket plate be frictionally held from displacement at any point
of sliding adjustment given thereto.
When it is desired to positively retain the bracket arm at any definite point
on the bracket plate a detent lever is employed, preferably formed of resilient wire
bent of the desired form, one end portion of the lever being pivoted transversely
in the slotted bracket arm near the clasping portion of the same. A protuberance
is formed on the side of the arm which will be engaged by the resilient body of
the lever if the latter is swung over it and this will adapt the lever to draw
together the two members of the bracket arm. The provision of the clamping
lever affords means to draw the clamping members of the bracket arm tightly
upon the bracket plate when the lever is swung into the desired position, a
lateral swinging movement of said lever serving to release the bracket arm for
movement to a desired point on the bracket plate.
On the free outer end of the bracket arm a boss is preferably formed which
is laterally perforated half way through the same and in alignment with the said
perforation a horizontal slot is produced in the remaining portion of the boss.
There may be, and preferably are, duplicate perforations and slots formed in the
boss at two points at right angles to each other, and the perforations may be
round or angular as the pivots on the blind roller may require.
It will be seen that when two of the improved blind fixtures are to be employed
for rotatably supporting a roller for a blind upon the casing of a window, each
fixture may readily be clamped by an adjustment of the clamping bar and the
limb thereon by means of the screw. When both of the fixtures that have
been described are clamped upon the window casing near the cap piece
of the same, the bracket arms will lie in the same horizontal plane. The perfora-
tion in one arm will receive the cylindrical pivot of the blind roller and if said
roller is of a type adapted to automatically roll up the blind thereon, the usual
flattened pivot at the other end of the roller will enter the slot of the opposite bracket
arm and thus adapt the roller for efficient operation in the usual manner.
The pair of fixtures for a window may be clamped upon the transverse mould-
ing at the top of the window casing with the same facility as upon the side
mouldings therefor. In this case the perforations and slots in the enlargements
on the ends of the bracket arms, and which are at right angles to those occupied
by the roller pivots when the bracket arms are disposed as before described, be-
come available for reception of said pivots and the depending arms.
adapted to carry the blind roller.
are thus
A pair of light metal pole supporting bracket frames can be attached upon the
bracket plates of a pair of blind fixtures embodying the improvements. Said
bracket frames may be of any ornamental design and be constructed of sheet
metal or other material, it being mainly essential that a dovetail recess be formed
in the back of each bracket frame so that the pair of frames may be slid upon the
plates and clasp them whereby the pole supporting bracket frames will be sus-
tained in a correct position.
It. will be obvious that the improved fixtures may in pairs be used indiscrimin-
ately for either the right-hand or left-hand sides of a window which renders the
improvements available for general use in a convenient manner.
As hereinbefore described the preferred use for the improved fixture is to sup-
port window blinds and curtain poles at windows but it is also well adapted for
attachment of a shelf bracket upon a projection from a side wall or other stable
object and also may be employed to attach pillow sham holders upon a bedstead.

page_text: Improvements in Mountings or Supports for Window Blind Rollers,
Curtain Poles, Wall Brackets, and other objects.
I, GEORGE BIEHN, of North Yakima, in the County of Yakima, and State of
Washington, United States of America, Merchant, 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 fixtures and has for its object to provide
fixtures which are adapted for ready attachment upon the side or top mouldings
of window casings, without the use of wood screws or nails, so as to afford reliable
support for the window blind at a desired point of the casing, and also enable the
easy removal of said fixtures without the use of tools.
A further object is to provide a device of the indicated character, with novel
bracket supports for a curtain pole, which are likewise adapted for attachment or
removal without a tool, as occasion may require.
The invention essentially consists in the novel construction and combination
of parts, as is hereinafter described and pointed out in the appended 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 plan view of the improved fixture engaging one end of a blind
roller, and clamping upon a side moulding of the casing of a window, said mould-
ing and the blind roller being represented by dotted lines;
Figure 2 is a side view of the fixture, seen in direction of the arrow x in
Figure 1;
Figure 3 is an enlarged transverse sectional view, essentially on the line 3-3
in Figure 1;
Figure 4 is an end view of the improved blind fixture clamped in place upon
a side moulding of a window frame, and supporting a novel constructed curtain
pole bracket; and;
Figure 5 is a detail section on the line 5-5 of Figure 3.
The improved blind fixture is to be provided in duplicate for the support of
each end of a blind roller A, upon both sides of a window casing, one of the
casing side portions being indicated in plan by dotted lines at B, in Figure 1,
to show the application of the improvement thereon.
Each one of a pair of fixtures required to support a blind at a window, consists
of the following described parts. An elongated bracket plate 10 is provided,
having its side edges a, bent inwardly to provide a shallow recess, that is dove-
tailed in cross section, as shown in Figure 3. At one end of the bracket plate 10
a limb 11 is secured by its foot b.
A clamping bar 12 is adapted to engage its side edges with the inwardly bent
edge portions a of the bracket plate 10, when inserted endwise within the shallow
open recess formed for its reception in said bracket plate.
The clamping bar 12 is longitudinally slotted as at a to lighten it, and also to
permit the free introduction therein of a long adjusting screw 13, which has a
suitable engagement with a perforation in the base of the limb 11, and a like
engagement with a tapped hole in the cross bar dat one end of the clamping bar,
as is shown in Figure 2. The adjusting screw 13 is furnished with a milled
head 13 for its convenient manipulation when the bracket plate is to be secured
in place or released.
On the end of the clamping bar 12 which is opposite from that engaged by
the adjusting screw 13, a limb 14, is formed or secured, which is similar to the

page_text: limb 11, both of said limbs having teeth d, projected at their upper edges toward
the cross bar c¹ of the clamping bar.
A bracket arm 15, is fitted to slide upon the bracket plate 10, as best shown
in Figure 3, said arm comprising an elongated body having a widened base
portion e, which is recessed on the side that engages the bracket plate.
The recess in the base portion e, is undercut on the side edges or walls thereof,
so as to closely embrace the dove-tailed body of the clamping bar 12, when the
latter is engaged by the bracket arm 15.
A longitudinal slot g is centrally formed in the body of the arm 15, of sufficient
length to produce two similar clamping limbs thereon. If the material from
which the bracket arm 15 is formed will afford elasticity to the clamping limbs
mentioned, the arm will by the assured clasping engagement of said clamping
limbs with the bracket plate, be frictionally held from displacement at any point
of sliding adjustment given thereto.
When it is desired to positively retain the bracket arm 15 at any definite point
on the bracket plate 10, a detent lever 16 is employed, preferably formed of
resilient wire, bent into the form shown in Figure 3, one end portion of the lever
being pivoted transversely in the slotted arm 15 near the clasping portion e of
the same.
A protuberance h, is formed on the side of the arm 15, which will
be engaged by the resilient body of the lever 16 if the latter is swung over it, and
this will adapt the lever to draw together the two members of the bracket arm 15.
The provision of the clamping lever 16 affords means to draw the clamping
members of the bracket arm 15 tightly upon the bracket plate 10, when the lever
is swung into the position represented by full lines in Figures 1 and 3, a lateral
swinging movement of said lever into the position represented by dotted lines in
Figure 1 serving to release the bracket arm for movement to a desired point on
the bracket plate 10.
On the free outer end of the bracket arm 15 a boss m is preferably formed,
which is laterally perforated half way through the same, and in alignment with
the said perforation na horizontal slot o is produced in the remaining portion
of the boss, as shown in Figure 3. There may be, and preferably are, duplicate
perforations n and slots o formed in the boss m at two points at right angles to
each other. And the perforations may be round or angular as the pintles on
the blind roller may require.
It will be seen that when two of the improved fixtures are to be employed, for
rotatably supporting a roller for a blind upon the casing of a window, each
fixture may readily be clamped by an adjustment of the clamping bar 12 and
the limb 14 thereon by means of the screw 13, as is clearly indicated in Figure 1.
When both of the fixtures that have been described are clamped upon the window
casing near the cap piece of the same, the bracket arms 15 will lie in the same
horizontal plane. The perforation in one arm 15 will receive the cylindrical
pintle of the blind roller, and if said roller is of a type adapted to automatically
roll up the blind thereon, the usual flattened pintle at the other end of the roller
will enter the slot o of the opposite bracket arm and thus adapt the roller for
efficient operation in the usual manner.
The pair of fixtures for a window may be clamped upon the transverse mould-
ing at the top of the window casing, with the same facility as upon the side
mouldings therefor. In this case the perforations n and slots o in the enlarge-
ments m on the ends of the bracket arms 15, and which are at right angles to
those occupied by the roller pintles when the bracket arms are disposed as shown
in Figure 1, become available for reception of said pintles, and the depending
arms 15 are thus adapted to carry the blind roller such as A.
A pair of light metal pole supporting bracket frames 18 can be attached upon
the bracket plates 10 of a pair of blind fixtures embodying the improvements.
Said bracket frames may be of any ornamental design, and be constructed of
sheet metal or other material, it being mainly essential that a dove-tail recess ?'
be formed in the back of each bracket frame 18, so that the pair of frames may

page_text: be slid upon the plates 10 and clasp them, whereby the pole supporting bracket
frames will be sustained in a correct position for their designated service.
It will be obvious that the improved fixtures may in pairs be used indis-
criminately for either the right-hand or left hand sides of a window, which renders
the improvements available for general use in a convenient manner.
As hereinbefore described, the preferred use for the improved fixture, is to
support window blinds and curtain poles at windows; but it is also well adapted
for attachment of a shelf bracket upon a projection from a side wall, or other
stable object, and also may be employed to attach pillow sham holders upon a
bedstead.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is;
1. A curtain bracket arm provided at its inner end with a base portion adapted
to engage the bracket plate and at its outer end with a plurality of seats for the
roller stud, said seats being arranged at right angles to each other and being
fixed with relation to the base portion of the arm, substantially as described.
2. A curtain bracket arm provided at its outer end with a round seat for the
round roller stud and opposite thereto and in a plane lateral to said round seat
with a slot for the angular stud of said roller, substantially as described.
3. A curtain bracket arm provided at its outer end with a plurality of sets
of seats for the roller studs, each set consisting of a round opening for the round
stud and a slotted opening lateral to said round opening for the square stud, the
slotted opening of each set being arranged opposite its respective round opening,
substantially as described.
4. In a blind fixture, the combination of the plate or support and the bracket
iron divided at its inner end forming clamping sections gripping the opposite
sides of the support, the clamping lever connecting said sections and removable
as described, and a protuberance upon which said lever binds to clamp the sections
together, substantially as described.
5. A curtain fixture comprising the bracket plate having dovetail edge plates
or flanges, the clamping bar having dovetail edge plates or flanges slidably
engaged with those of the bracket plate and the screw by which to adjust said
parts, substantially as described.
6. The herein described improvement in blind fixtures comprising the bracket
arm divided at its inner end by a longitudinal slit and adapted at such end to
engage with the bracket-plate or support and a lever having a shank extended
through both sections of the bracket arm connecting the same and journaled
therein as described and having a swinging portion which turns into and out of
engagement with a bearing portion on one of the arm sections, substantially as
shown and described.
