A Mechanical Device for Raising Windowsashes, Shutters, Doors,
Partitions, and Blinds (or Curtains) to a Given Position, and (by
Means of a Holder) to Retain them in the Place Required.
I, JOSEPH SIMPSON, 1 Brook Road, Heaton Chapel, (near Stockport) in the County
of Lancashire, Engineer, do hereby declare the nature of this invention to be as
follows:-
To accomplish this object, moveable pulleys (or a roller) are affixed to the frame or
sash, under which is passed a cord or belt; one end being secured to the permanent
framework, and the remaining one carried over other pulleys (or a roller) to a
position convenient for moving by hand.
In consequence of the leverage of the moveable pulleys (or roller) being in the ratio
of two to one, the power requisite to lift a windowsash (or any of the articles before
mentioned) is reduced one half.
For the purpose of retaining the windowsash at any required height, an
eccentric roller is introduced which is moved to or from the sash by a lever. This
lever may be acted upon by the tension of the cord or belt, or by the hand, so as to
keep the sash in a given position by friction or the same may be effected by its being
turned so as to come under a shoulder (when the sash has reached the desired position)
which will hold it there.
In order to keep steady the upper part of the sash, a ball (or roller) resting loosely
on an inclined surface of the permanent part is arranged, which by its pressure against
the sash, holds it firm, through its resistance against the inclined surface.
In the case of shutters--doors and partitions of large size and great weight,
moveable pulleys are used in combination with a roller (or barrel,) whereon the cords
are wound (unless substituted by chains ;) which roller (or barrel) is in turn moved
round by a cord (or Gearing) upon a part of it of greater diameter.
In either case increased power, in addition to the moveable pulleys is exerted
apon the shutter-door-or partition, whereby it may be lifted and lowered more
asily.

With regard to holding the said shutters-doors-or partitions in
Tover
position, a Break wheel is attached to the roller (or barrel) and is relieved by a
which is controlled by the tension of the cord in the same manner as though it were
worked by hand; that is to say, they aro held in position by friction.
In the case of blinds (or curtains) a roller is used fitted with a breakwheel with
lovers and cord communication as described above, for shutters-doors-&c.
Where stretching of the blind (or curtain) is requisite, a system of lovers (arranged
as "lazytongs") is employed for the vertical movement, and transverse bars at
intervals are connected to the levers for securing the width.
When the blinds (or curtains) are large and consequently heavy, moveable pulleys
are applied to the "lazytongs," which are threaded with cords and wound upon a
roller, as above described. Or they may be drawn up by the hands applied to the
cords direct.
In either caso an increased power is brought to bear upon the weight, which is raised
more easily in consequence.
In the case of small blinds for carriage windows, "lazytongs" and transverse bars
are used to stretch the blind, which is moved up or down to any position directly by
the hand, the friction of the numerous joints in the "lazytongs" being sufficient to
hold the blind at any height desired.

Partitions, and Blinds (or Curtains) to a Given Position, and (by

I, JOSEPH SIMPSON, residing at No. 1, Brook Road, Heaton Norris, in the county
of Lancashire, Engineer do hereby declare the nature of iny invention for RAISING
WINDOW SASHES AND OTHER OBJECTS (named above) and in what manner the same
is to be performed, to be particularly described and ascertained in and by the:
following statement :-
I attach to the said window sash (or other object) moveable pulleys (or a roller).
pass a cord (or belt) under the said pulleys (or roller,) the return end is fastened to
the framing. By drawing at the loose end of the cord (or belt) the effect of the
noveable pulley (or roller) is to give a leverage of two to one and consequently the
power required to raise the window sash, (or other object named above,) is reduced
to one half the actual weight to be raised.
The holder for retaining the window sash in any position, consists of an eccentrically
pivoted roller, which is moved to or from the sash by the tension of the cord (or
bolt) acting upon the projections at the sides of the roller, turning it partially
round, bringing the larger side of the eccentric portion to press against the sash
and hold it in the required position. This movement of the eccentric roller may be
effected by the hand operating upon a suitable lever.
The eccentric roller may be arranged to come under a shoulder formed at (or near)
the bottom of the sash, and thereby to retain it in its closed position.
In order to keep steady the upper part of the sash, a ball (or roller) resting loosely
upon an inclined surface (of the permanent part,) is arranged, which by its pressure
against the upper part of the sash, holds it firin through its resistance against the
inclined surface.
In the case of Shutters-Doors and other objects (of large size and great weight,)
moveable pulleys are used, in combination with a roller (or barrel) whereon the cords
are wound (unless substituted with chains ;) which roller (or barrel) is moved round
by a cord (or gearing) acting upon a part of it of greater diameter. In either case,
increased power, in addition to that of the moveable pulleys is exerted upon the
Shutter Door, or other object, whereby it may be lifted, and lowered more easily.
For the purpose of bolding the said Shutter-Door (or other object) in any given
position, a Brakewheel is attached to the roller (or barrel) at the ends of the roller pivots
are attached, one resting upon a fixed bearing the other supported by a lever, which
is carried at one end by a pin, whilst the other end is moveablo, at the centre of the
lever there is a recess in which the pivot (at the other end of the roller) works. The
moveuble end of the lever is carried by the short end of a bellcrank lever, at the lower
end of which there is a slot, into which a pulley is inserted for the operating cord to
pass over.
