PROVISIONAL SPECIFICATION.
An Apparatus for Holding the Unused Portion of a Venetian Blind
at the Top of the Window.
I, WILLIAM HENRY GREATOREX of 11 Forthbridge Road New Wandsworth
in the County of Surrey do hereby declare the nature of this invention to be as
follows:-
My invention relates to an apparatus for storing the laths of an ordinary
Venetian blind at the top of the window to which it is fitted, and dividing the
laths of the said blind, into two, three four or more sections, each section consisting
of any number of the laths contained in the blind, and by means of the said
apparatus releasing only such section or sections of the blind, as are to be brought
into use, the said portion so released being under the control of the cord ordinarily
used for raising or lowering the blind, the laths of the released portion being
adjusted in their relation to the light by means of a roller arrangement fitted to
each section.
The object of my invention is to prevent the unsightly appearance observable in
ordinary Venetian blinds, occasioned by the unused portion of the blind being
suspended in a mass at the bottom of the laths in use, also to obviate the
serious objection, that the said mass of laths are an obstacle to the admission of
light.
To carry out my invention I proceed as follows.
When the blind is gathered up at the top of the window, instead of allowing
all the laths to abut closely together, I first determine into how many sections the
laths that form the blind are to be divided, also the number of laths in each
section. Then as the division of the blind into three sections will involve the
whole principle of my invention I will take that number for the purposes of this
specification.
But I wish it to be understood that by my invention the blind can be divided
into two three four or more sections as may be desired.
Then having determined that the lower section shall consist of nine laths, and
the second or middle section of twelve laths the top or third section will then
consist of the remainder of the blind.
I now take the tenth and twenty second laths and to each of the said laths
I fix two brackets in such a position, that they will be hidden by the ladders of
the blind then on both sides and on a line with the cross tapes that unite the
vertical webs of the ladder of the blind and upon which rests the next lower
or as in the present case the ninth and twenty first laths, I attach a cord
or tape to run over a small roller or pulley attached to the above mentioned
brackets.
For the purposes of this specification I will in future call the above mentioned
brackets, "roller brackets."
The purpose of these roller brackets is on the one hand to allow the released
section or sections of the blind to have their laths adjusted in their relation to the
light.
In the second place the roller brackets form distancing stops to prevent the
lath above the roller brackets from abutting on the lath below the said brackets
thus leaving an open space at each of the positions of the blind that are furnished

page_text: with the said roller brackets. It may be desirable to use strips of wood or other
substance in convenient positions to insure the abovementioned open spaces being
effectually kept from closing in.
The laths are adjusted in their relation to the light from the bottom of the blind,
unless the whole of the laths are released, in which case they can be adjusted from
the top or bottom of the blind.
I will now proceed to explain by what means I store the laths of the blind
at the top of the window and allow the said laths to be released in seperate
sections.
I fix a rectangular frame at the top of the window, whose horizontal sides reach
across the width of the window to which it is fitted, and are held in their position
by the two vertical sides the said vertical sides being screwed to the woodwork of
the window frame, act both as brackets to carry the frame, and distancing pieces
to give the requisite width to the said frame, I will for the purposes of this
specification in future call the above frame the carrying frame.
The carrying frame is in such a position, that when the blind is drawn up home,
the spaces between the laths herein before mentioned are utilized in the manner
following.
I fit to the carrying frame one two or more vertical rods as may be determined
these rods carry brackets, the bosses of the said brackets are bored to allow them
to turn freely on the above mentioned vertical rods, an arm projects from the said
boss in a horizontal direction, and on the opposite side of the boss, and on the
same horizontal plane as the arm, a short tail piece projects with a slott cut in a
vertical direction the said tail piece is set at an angle to the arm as hereinafter
explained.
For the purposes of this specification I will call the above mentioned brackets
supporting brackets.
Then as above stated the carrying frame is fixed in such a position that as the
supporting brackets revolve on the vertical rods the arms will pass freely in and
out of the open spaces above mentioned so that the said arms can be thrown at
right angles to the carrying frame across the width of the laths, and thus support
that portion of the blind which is above the carrying brackets, allowing the
remainder of the blind not so supported to be under the control of the cords used
for raising and lowering the blind in the ordinary manner.
The said unsupported or released section or sections of the blind are adjusted
in relation to the light from the bottom bar by means of the roller brackets.
To actuate the supporting brackets I have a horizontal rod fitted at a suitable
distance above each of the openings hereiubefore mentioned formed by the roller
brackets, the above roda oscillate freely in a horizontal direction, in bearings fixed
to support and hold them in their desired position on the carrying frame, the above
mentioned oscillating rods have vertical pins depending in a downward direction
the said pins engage in the slotted tail pieces of the supporting brackets herein-
before mentioned. The said tail pieces must be set at such an angle to the arms
of the supporting brackets, that they will not lock themselves or foul the gearing,
whether the arms be in their rectangular position with the carrying frame across
the width of the laths to support the same or lying parallel with the said laths to
allow them to be freely raised or lowered.
To give the necessary throw to the supporting brackets by means of the
oscillating rods hereinbefore mentioned I actuate the said rods in the following
manner.
I fix a vertical rod to one end of the carrying frame preferably on the right
hand side of the frame and for every oscillating rod I have a link and distancing
arm attached to the said vertical rod in the following manner.
In the arrangement herein-specified the above mentioned vertical rod would require
to be fitted up with two link arrangements to support the top and middle sections of
the blind the lower section being controlled by means of the ordinary cord for
raising and lowering the blind.

page_text: I will now proceed to explain the method of fixing the link and arm for
actuating the top oscillating rod.
The link is suspended from a pin fitted to the before mentioned vertical rod at
the top of the said rod as a fixture upon which pin the said link freely works, the
bottom end of the link is cranked out at right angles the said cranked piece is
bored out to engage with the end of the oscillating rod, for this purpose the end
of the said rod is turned down at right angles and is made to hook into the cranked
end of the link in which it very freely works. I have a socket or sleeve bored a
sliding fit to travel on the vertical rod, to the said sleeve is pinned at a working fit
one end of the distancing arın herein before mentioned, the other end of the said
arm is pinned to the suspended link as near to the cranked piece as convenient,
and is also a working fit with the link. The length of the said distancing arm is
such, that when it stands in a horizontal position it will hold the cranked end of
the link at its farthest point from the vertical rod, and thus will actuate the
oscillating rod hooked into the cranked end of the link as hereinbefore explained in
such a manner that the supporting bracket or brackets will have their arms thrown
in a rectangular direction across the width of the laths of the blind and so hold
that section of the blind resting on the supporting brackets at the desired position
at the top of the window, again when the sliding socket on the vertical rod herein-
before mentioned, to which the distancing arm is attached is pulled down so as to
approach a vertical position the link carrying the oscillating rod attached thereto
is drawn towards the vertical rod with the result that the arms of the supporting
brackets are thrown in a horizontal position, to clear the blind and allow the
freed portion of the blind to be raised and lowered by the cord in the ordinary
manner.
The link arrangement for actuating the second or lower oscillating rod is fixed
to the travelling socket or sleeve on the vertical rod to which the distancing arm
of the first or top link is attached, the arrangement being identical with that for
actuating the first or top oscillating rod, with this exception. The first or top link
is always a fixed pcint, at the end attached to the top of the vertical rod herein-
before mentioned, but the second or lower link is fitted as above stated to the
travelling socket to which same socket is fixed the distancing arm, attached at its
outer end to the link of the top arrangement, that is the one immediately above,
and in all cases, the increasing of the number of sections to the blind would involve
a repetition of the second or lower link arrangement.
To conveniently actuate the above mentioned link arrangements I attach a rod
or long arm to the sleeves or travelling sockets hereinbefore mentioned, the lower
end of the said arm is within easy reach of the operator.
I will suppose the distancing arm to be in a horizontal position, then, the above
mentioned long arm is secured by a pin to the lowest travelling socket as a fixture,
but the pin in the travelling socket next above is not so fixed to the long arm, but
the said long arm is slotted out to such a length, that the lower link will have to
be pulled down to its vertical position thus liberating the second or middle section
of the blind before the long arm will engage with the pin attached to the travelling
socket next above, when if desired the section above the one last released can also
by the same process, be brought into use.
For fastening the above mentioned long arm at each position of the link
arrangements the said long arm is perforated with holes at its lower end, at suitable
distances from each other, the said perforated holes engage with a knob at each
position, fitted to the frame of the window for that purpose.

page_text: An Apparatus for Holding the Unused Portion of a Venetian Blind
at the Top of the Window.
I WILLIAM HENRY GREATOREX of 11 Forthbridge Road New Waudsworth,
in the County of Surrey Brassfinisher 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 an apparatus for storing the laths of an ordinary Venetian
blind at the top of the window to which it is fitted, and dividing the laths of the
said blind into two, three, four or more sections each section consisting of any
number of the laths contained in the blind, and by means of the said apparatus
releasing only such section or sections of the blind as are to be brought into use,
the said portion so released being under the control of the cord ordinarily used for
raising or lowering the blind, the laths of the released portion being adjusted in
their relation to the light by means of a roller arrangement fitted to each section.
The object of my invention is to prevent the unsightly appearance observable in
ordinary Venetian blinds, occasioned by the unused portion of the blind, being
suspended in a mass at the bottom of the laths in use, also to obviate the serious
objection, riz., that the said mass of laths are an obstacle to the admission of
light.
To carry out my invention I proceed as follows.
When the blind is gathered up at the top of the window, instead of allowing all
the laths to abut closely together I first determine into how many sections the
laths that compose the blind are to be divided, also the number of laths in each
section.
Then as the division of the blind into three sections will involve the whole
principle of my invention, 1 will take that number for the purposes of this
specification.
But I wish it to be understood that by my invention the blind can be divided
into two, three, four, or more sections as may be desired.
Then having determined that the lower section shall consist of nine laths and the
second or middle section of twelve laths, the third or top section will then consist
of the remainder of the blind.
I now take the tenth and twenty second laths, counting from the bottom of the
blind, and to each of the said laths I fix two brackets in such a position that they
will be hidden by the webs of the blind then on both sides and on a line with the
cross tapes or ladders that unite the vertical webs of the blind, and upon which
rests the next lower, or as in the present case, the ninth and twenty first laths
I attach, a cord or tape to run over a small pulley or roller attached to the
abovementioned brackets.
For the purposes of this specification I will in future call the above mentioned
brackets roller brackets.
The purpose of these roller brackets is on the one hand to allow the released
section or sections of the blind to have their laths adjusted in their relation to the
light, in the second place the roller brackets form distancing stops, to prevent the
lath above the roller brackets to which they are attached, from abutting on the lath
below the roller bracket thus leaving an open space at each of the positions of the
blind that are furnished with the said roller brackets.
It may be desirable to use strips of wood or other substance in convenient
positions to insure the above mentioned open spaces being effectually kept from
closing in.
The laths are adjusted in their relation to the light from the bottom of the blind

page_text: unless the whole of the laths are released in which case they can be adjusted either
from the top or bottom of the blind.
I will now proceed to explain by what means, I store the laths of the blind at the
top of the window, and allow the said laths to be released in seperate sections.
I fix a rectangular frame at the top of the window, whose horizontal sides
reach across the width of the window, to which it is fitted and are held in their
position by the two vertical sides, the said vertical sides being screwed to the
woodwork of the window frame, serve both as brackets to carry the frame, and
distancing pieces to give the requisite width to the said frame.
I will for the purposes of this specification in future call the above mentioned
frame the carrying frame.
The carrying frame is in such a position that when the blind is drawn up home,
the spaces between the laths formed by the roller brackets herein before mentioned
are utilized in the following manner.
I fit to the carrying frame one, two, or more vertical rods as may be determined,
the said rods carry brackets the boss of the said brackets are bored to allow them
to turn freely on the abovementioned vertical rods, an arm projects from the said
boss, in a horizontal direction and on the opposite side of the boss, and on
the same horizontal plane as the arm a short tail piece projects with a slott cut
in a vertical direction, the said tail piece is set at an angle to the arm as hereinafter
explained.
For the purposes of this specification I will call the above mentioned brackets
supporting brackets.
Then as hereinbefore stated the carrying frame is fixed in such a position, that
as the supporting brackets revolve on the vertical rods the arms will pass freely in
and out of the open spaces herein before mentioned so that the said arms can be
thrown at right angles to the carrying frame across the width of the laths and thus
support that portion of the blind which is above the carrying brackets allowing the
remainder of the blind not so supported to be under the control of the cords
used for raising and lowering the blind in the ordinary manner. The said
unsupported or first section-or the released section or sections of the blind are
adjusted in relation to the light from the bottom bar by means of the roller
brackets,
To actuate the supporting brackets I have a horizontal rod fitted at a suitable
distance above each of the openings formed by the roller brackets herein before
mentioned, the said rods oscillate freely in a horizontal direction in bearings fixed
to the carrying frame to hold them in the desired position.
The above mentioned oscillating rods bave vertical pins depending in a downward
direction, the said pins engage, in the slotted tail pieces of the supporting brackets
bereinbefore mentioned, the said tail pieces must be set at such an angle to the
arms of the supporting brackets that they will not lock themselves or foul the
gearing whether the arms be in their rectangular position with the carrying frame
across the width of the laths to support the same, or lying parallel to the said
laths to allow them to be freely raised or lowered.
To give the necessary throw to the supporting brackets by means of the
oscillating rods hereinbefore mentioned I actuate the said rods in the following
mauner.
I fix a vertical rod to one end of the carrying frame preferably on the right hand
side of the frame, and for every oscillating rod I have a link and distancing arm
attached to the said vertical rod in the following manner.
In the arrangement herein specified the above mentioned vertical rod would
require to be fitted up with two link arrangements, to support the top and middle
sections of the blind the lower section being in all cases controlled by means of the
cord in use for raising and lowering the blind.
I will now proceed to explain the method of fixing the link and distancing arm
for actuating the top oscillating rod.
The said link is suspended from a pin fitted to, or near to, the top of the vertical

page_text: rod bereinbefore mentioned at a fixed point, and upon which point it freely works,
then the bottom end of the link is cranked out, at right angles the cranked end is
bored out to engage with the end of the oscillating rod, for this purpose the end of
the said rod is turned down at right angles and is made to hook into the bore of
the cranked end of the link in which it very freely works.
I have a socket or sleeve bored a sliding fit to travel on the vertical rod, to the
said sleeve is pinned at a working fit one end of the distancing arm hereinbefore
mentioned, the other end of the said arm is pinned to the suspended link, herein-
before mentioned as near to the cranked end of the said link as convenient and
also at a working fit.
The length of the said distancing arm is such that when it stands in a
horizontal position it will hold the cranked end of the link at its farthest point
from the vertical rod, and this will actuate the oscillating rod, hooked into the
cranked end of the link, as hereinbefore explained, in such a manner that the
supporting bracket or brackets will have their arms thrown in a rectangular
direction across the width of the laths of the blind the throw thus given to the
supporting brackets being obtained by the pins depending from the oscillating rod
engaging in the slott in the tail piece of the supporting bracket as hereinbefore
mentioned, and the angle of the said tail piece with the arm of the supporting
bracket being such, that taking a centre line through the length of the said arm, it
will have a race of ninety degrees or from a horizontal to a rectangular position,
so that when the said arms of the supporting brackets are in their rectangular
position, that portion of the blind resting upon them will be held at the top of the
window.
Again when the sliding socket on the vertical rod herein before mentioned, to
which the distancing arm is attached, is pulled down, so as to approach a vertical
position the link engaging with the oscillating rod, is drawn towards the vertical
rod, with the result, that, the supporting brackets, actuated as herein before
explained, are thrown in a horizontal position, to clear the blind, and allow the
freed portion of the laths to be raised and lowered by the cord in the ordinary
manner.
The link and arm arrangement for actuating the second or lower oscillating rod,
is fixed to the travelling socket or sleeve on the vertical rod to which the distancing.
arm of the first or top link is attached, the arrangement being identical with that
for actuating the first or top oscillating rod, with this exception, the first or top link
is always a fixed point-at that end attached to or near the top of the vertical
rod herein before mentioned, but, the second or next lower link is fitted as above
stated to the travelling socket, to which same socket is fixed the distancing arm
attached at its outer end to the link of the top arrangement, that is, to the one
immediately above, the distancing arm for this second link, is fitted to a sleeve or
socket on the vertical rod in the same manner as the one above.
And in all cases the increasing of the number of sections to the blind would
involve a repetition of the second or lower link arrangement.
To conveniently actuate the above-mentioned link arrangements I attach a rod
or long arm to the sleeves or travelling sockets hereinbefore mentioned in the
following manner.
I will suppose the distancing arms to be in a horizontal position, then the above-
mentioned long arm is secured by a pin or screw to the lowest travelling socket as
a fixture, but the pin in the travelling socket next above is not so fixed to the long
arm, but the said long arm is slotted out-to such a length that the lower link will
have to be pulled down to its vertical position, thus liberating the second or in the
present arrangement 'the middle section, of the blind, before the long arm will
engage with the pin attached to the travelling socket next above.
But this said position being attained the section next above the last-section
released, ran by the same process be brought into use.
For fastening the above mentioned long arm at each position of the link
arrangement. The said long arm is perforated with holes at the lower end at

page_text: Editable distances from each other the said perforated notes engage with a knoo
at each position or adjustment of the blind-the said knob being fitted to the frame
of the window for that purpose.
In the accompanying drawing-
Figure 1. represents my invention as applied to an ordinary window casement
with Venetian blind.
Figure 2. is a section of the same.
Figure 3. is an enlarged perspective view of my invention.
Figure 4. is a perspective view of one of the supporting brackets on an enlarged
scale.
Figure 5. is a perspective view of part of the laths and webbing of a Venetian
blind shewing the pulley and tape in position..
Figure 6. is an elevation of the same in section.
Figure 7. is a cross section of the same.
Like letters indicate the same parts throughout the drawing.
A. A A A Figures 1. and 3. represent the carrying frame-the ends of the
horizontal rods A. A' are made a fixture in the lugs of the vertical bracket A³
Figure 3, but slide in the lugs of A2 and are held in position by set scre vs as
shewn-this allows the rods A, A¹ to be cut to suit the width of the casement.
The carrying frame is held in its position on the casement by screwing the vertical
brackets A2 A3 to the uprights of the said casement.
The vertical rods C. C upon which the supporting brackets D. D1 D2 D³
revolve at the bore b. 61 63 63-are screwed into the sockets B. B' B2 B3 the said
sockets slide on the rods A. A' of the carrying frame and are held in position by
set screws as shewn.
When the arms of the supporting brackets D stand with their centre line
parallel with the horizontal rods A. A' the blind will be freed from the control of
the apparatus.
But when they stand in a rectangular direction to the rods A. A' they support
the sections of the blind resting upon them.
To obtain this alternate position of the supporting brackets D. D' D² D³ the
oscillating rods F F are fitted with the adjustable sockets N. N N N from
which depend the vertical pins n. n n n engageing respectively with the
slotts d. d d d in the tail pieces of the supporting brackets D. D1 D2 D3 the
said slott d. stands at an angle of 45° with a centre line through the arm of
the supporting bracket D.
Thus when the rods F. F' are made to recede from the bracket A³ the
pins n. n' n² no engaging respectively with the slotts d. d d d will throw the arm
of the supporting brackets D. D' D2 D3 between the openings a. a¹ in a rectangular
direction with the rods A. A' Figure 1.
Again when the oscillating rods FF1 are made to approach the bracket A³
the reverse operation will take place with the supporting brackets D. D' D' D'
and the arms will be thrown in a horizontal direction with the rods A A¹.
The rods F F run in bearings bored in a horizontal direction through the
thickness of the adjustable vertical brackets E. E' and are thus held in their true
horizontal position.
To give the requisite advance and receding movement to the rods F. F¹ and
thus imparting the throw to the supporting brackets D. D D D³ the links H. H'
and distancing arms I. 1 with the long arm L are attached to the vertical
bracket A and connected with the rods F F1 in the following manner.
The vertical rod K., Figures 1. 3. runs from end to end of the bracket A' and is
secured to the bosses C C₁.
The link H. is hung from a stud in the boss C. and is a fixed point-the
distancing arm 1 works on a pin at the lower end of the link H. and the other
end works on a pin in the ear of the sleeve J. travelling on the vertical rod K. the
end of the oscillating rod F is turned at right angles to engage with the bore / in
the cranked end of the link H.

page_text: By this arrangement when the distancing arm I. approaches a horizontal
direction, the rod F will recede from the bracket A as hereinbefore explained
the arms of the supporting brackets D. D' will then be thrown in a rectangular
direction across the laths to support the third section.
When the sleeve J is made to travel in a downward direction on the rod K. the
link H and the distancing arm I will approach a vertical position and cause the
oscillating rod F to advance towards the bracket A and thus the supporting
brackets DD' will be thrown from their rectangular to their horizontal position
to free the section of the blind under their control.
In the second link arrangement the link H' is suspended from the ear of the
sleeve J and works on the pin holding the distancing arm I the bore A of the
cranked end of the link H engages with the vertical end of the rod F¹ and
the distancing arm I' is attached to the link H' and to the sleeve J.
To actuate the link arrangements when in their position at the top of the
casement I attach to the sleeves J, J' the long arm L, thus, I will assume that
the distancing arms I I' stand in a horizontal direction.
Then I make a fixture at W' of the long arm L to the sleeve J-but in the
sleeve J. the slott . in the long arm L runs freely over the stud W the race of
the slott being equal to the travel given to the sleeve J in actuating the oscillating
rod F.
The long arm L runs in a vertical direction through the guide X. and the
perforated holes o. o' o engage with the knob y in the plate Y in the following
manner.
In the conditions above specified with the distancing arms 1. I standing in a
horizontal direction then the knob y would have to engage with the hole o² in the
long arm L. Fig. 1 when the third or top section of the blind would be held
up by the supporting brackets D D' the second section by the supporting
brackets D' D.
The first section being in this instance the bottom portion of the blind which
is always left free to be controlled by the cords in the ordinary manner, can be
raised or lowered independantly of the apparatus.
To release the second section the long arm L must be pulled down until the
knob y engages with the hole o' when the link H' and the distancing arm 1' will
have approached a vertical direction thus actuating the oscillating rod F' and the
supporting brackets D' D' as hereinbefore described throwing the arms of the
supporting brackets D' D in a horizontal direction to clear the blind so allowing
the second section to be under the control of the cords.
The open spring G runs on the rod F and is confined between the bracket E
and the cranked end of the rod F to assist the action of the second link
arrangement.
In releasing the second sections of the blind the slott 7. in the long arm L will
have raced over the stud W. Figures 1. 3. so that the top of the slott l. will be in
contact with the stud W. enabling the long arm L to actuate the sleeve J-and
Dow by pulling the long arm L in a downward direction until the knob y engages
with the hole o the link H and the distancing arm I will in their tu proach
a vertical direction and actuate the rod F and supporting brackets 1. in a
similar manner to that in the release of the second section so liberating the
whole of the blind and placing it under the control of the cord in the ordinary
manner.
The close spring G. attached to the boss c. and the sleeve J is for the purpose
of retarding the action of the top link arrangement during the release of the second
section of the blind.
To replace and hold the blind at the top of the window it must be drawn up by
the cord and the long arm L pushed up until the knob y engages with the hole o
Figure 1.
In Figures 5. 6. 7. the arrangement is shewn by which I adjust the laths of the
released sections of the blind in their relation to the light.

page_text: S is the roller bracket secured to the under side of the lath by the screws V. V₁
engaging with the plate U on the opposite side of the lath, the spindle Q supported
by the roller bracket S. carries the roller R-the tape T runs over the roller R
and is sewn or fastened by the safety pins P. P¹ to the webbing on both sides and
on a horizontal line with the lath immediately under that to which the roller
bracket S is fixed.
Two or more of the roller bracket arrangements are required to each section.
In Figure 6 the position of the roller bracket S. on the webbing, to clear the
cord is shewn.
To adjust the laths in their relation to the light it is evident, that, if the webbing.
is pulled in a downward direction, by means of a cord on the lower rail or lath, on
either side, the tape T will follow it, and the ladders upon which the lathe rest
will assume a vertical position, and the laths necessarily be carried with them.
As hereinhefore stated when the whole blind is released, the laths can be adjusted
from either the top or bottom of the blind.
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 apparatus substantially as described in respect to Figures 1. 23 and 4,.
consisting of a carrying frame, to which is attached the supporting brackets, and
the apparatus for actuating the said supporting brackets for the purpose of
holding the unused portion of a Venetian blind at the top of the window and
enabling the said blind to be released in sections substantially as described.
2. The roller bracket arrangement substantially as described in respect to
Figures 5. 6 and 7. for the purpose of enabling the laths of the released section or
sections of a Venetian blind to which the apparatus is applied to be adjusted in.
their relation to the light. It also being an essential peculiararity that the said
roller brackets act as distancing stops to form the open spaces at each section,
to allow the supporting brackets to pass in and out of the said spaces, to support
or release the laths substantially as described.
