page_text: Improvements in and relating to Window-casings and Sash Frames.
I, THOMAS JONES, of No. 9, Southampton Row, in the County of Middlesex,
Manufacturers' Agent, do hereby declare, the nature of this invention to be as
follows:
; -
This invention relates to improvements in window-casings and sash-frames and
more especially for such as are used in asylums and like places. The objects of it
are; 1st, to hide from view and render inaccessible, the working parts thereof,
in order that they shall not be destroyed by or tampered with or present any
temptation to such to the inmates. 2nd. To prevent the sash-cords being frayed
by friction with the edges of the pulley when the window is turned.
According to my invention I construct the sashes of the reversible type and in
such manner as to allow the sashes to slide for a limited distance in the ordinary
way to meet the requirements of the Lunacy Commissioners and it also permits the
sashes to open inwards for cleaning or repairs of any description.
In carrying my invention into practice. I hinge the inside beads and attach to
them a special pivoted turn-button capable of being turned behind the stiles of
the lower sash by means of a special key only: the sashes are half rebated on the
outside of stiles to a distance of about half their height and the cords are affixed
to about the centre of them. The parting bead is made of metal or any other
suitable material to be removed or levered back into the pulley-stiles as hereatter
explained.
To the front sash in the lower rail thereof I fix bolt-pins or other suitable con-
trivances to serve as hinges or pivots upon which the said sash can be turned
inwards when desired. To the top sash, in the horns or vertical projections thereof
is fixed a thimble and below this at a suitable distance is fixed a bolt-pin or pivot,
which, when the sash is lowered to the distance required, acts as a stop and engages
with the said thimble for turning.
To render the cords invisible and inaccessible to the inmates, I fix at a suitable
distance from the top-rail and to the stiles, either the ordinary pulley or preferably
a special swivelled lazy-pulley with one wheel instead of two, hereinafter more
fully described, and the ordinary complementary tackle consisting of cords weights
etc., to operate the top sash. For the bottom sash I provide a double lazy-pulley
which is fixed in the pulley stile below the meeting rail through which the cords
pass, they being thus carried over a pulley at or near the top of the tackle box
and the said pulley is situated inside the box instead of, as is usual, in the stile
thus enclosing the cords entirely.
.
When the window requires cleaning or repairing, the turnbuttons attached
to the side heads as above stated are turned from behind the stiles of the lower
sash by means of a key through a key-hole made in the front sides of the window
casing and the bead opened forwards or inwards on its hinges and the bolt-pins or
pivots of the lower sash are shot into the pulley stiles, the top sash can then be

page_text: lowered on its pivots, the party bead is removed or levered backwards and the
sashes are turned horizontally inwards supported by the cords.
Obviously to close the window these actions must be reversed.
Now, the fixed lazy pulley before referred to, is swivelled as above stated, and,
by being capable of thus rocking on its centre the slight lateral play of the opening
window will be communicated through the cords to the said pulley wheel which
will give way to and take a direction in alignment with the cord and thus prevent
the fraying out or cutting of the edges-due to the friction of the cord on the
edges of the wheel of the cord which occurs with the ordinary fixed pulley wheel
whenever the cord is pulled at an angle to its plane. Should however the cords he
required to be strained at a greater angle than the swivelled pulley will be able
to follow, I provide a second pulley or antifriction roller beneath it to one side,
on which the cord will then take its bearing as desired.
The said lazy-pulley can be provided at the side with a pivotted roller, to further
prevent friction if required.
The lower sash is prevented from opening beyond a pre-determined distance by a
stop on the sash which catches against the wheel of the lazy-pulley or a stop on
the frame below the pulley, projecting, or any other such simple convenient means.
Dated the 16th day of October 1897.

1, Thomas JONES. of No. 9, Southampton Row, High Holborn, in the County of
Middlesex, Manufacturers' Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
nscertained in and by the following statement:—
This invention relates to improvements in window-casings and sash-frames and
moro especially for such as are used in asylums and like places. The objects of it
are (1) to hide from view and render inaccessible, the working parts thereof, in
order that they shall not be destroyed by or tampered with or present any templa-
tion to such to the inmates. (2) To prevent the sash cord from being frayed out
by the friction across the edges of the pulley when the window is pulled down.
According to my invention I construct the sushes of the reversible type, and in
such manner as to allow them to slide for a limited distance in the ordinary way,
to meet the requirements of the Lunacy Commissioners; and it also permits the
sashes to open inwards for cleaning or repairs of any description.
I will now proceed to fully describe my invention with reference to the accom-
panying drawings in which:.
:--
Figure 1 shows an elevation, a window casing or sash frame and reversible
window fitted and constructed according to my present invention.
Figure 2 is a sectional and elevation taken on the line 2-2 of Figure 1.
Figure 3 is a similar end elevation showing the sashes swung horizontally inward
for cleaning.
Figure 4 is an enlarged detail elevation of the style and swivelled lazy-pulley.
Figure 5 is a similar detail elevation showing the lazy-pulley in the position
when the window is swung inward.
Figure 6 is a sectional plan taken on the line (-6 of Figure 5.
I hinge the inside beads a and attach to them a special pivoted turn-button b

page_text: capable of being turned behind the stiles c of the lower sash d by means of a
special key only; the sashes are half rebated on the outside of stiles to a distance
of about half their height as shewn and the cords e, are affixed to about the centro
of them. The parting bead f is made of metal or any other suitable material to
be removed or levered back into the pulley stiles n', n² as hereafter explained.
To the front sash in the lower rail y thereof I fix bolt-pins or other suitable
contrivance h to serve as hinges or pivots upon which the said sash can be turned
inwards when desired. To the top sash i, in the horns or vertical projections j
thereof is fixed a thimble k and below this at a suitable distance is fixed a bolt pin
or pivot which, when the sash is lowered to the distance required, acts as a stop
and engages with the said thimble for turning.
To render the cords e invisible and inaccessible to the inmates, I fix at a suitable
distance from the top rail m and to the stiles n and n', either the ordinary pulley
or preferably a special swivel lazy-pulley 0 with one wheel instead of two, herein-
after more fully described, and the ordinary complementary tackle consisting of
cords weights etc., to operate the top sash. For the bottom sash I provide a double
lazy-pulley 03 which is fixed in the pulley stiles n', n below the meeting rail p
through which double pulley the cords pass, they being thus carried over a pulley
at or near the top of the tackle and the said pulley is situated inside the box c
instead of, as is usual, in the stile thus enclosing the cords entirely.
When the window requires cleaning or repairing the turn buttons b attached
to the side heads as above stated are turned from behind the stiles of the lower sash
by means of a key through a key-hole made in the front sides of the window
casing and the bead a opened forwards or inwards on its hinges and the bolt-pins
or pivots of the lower sash are shot into the pulley stiles n², the top sash i can
then be lowered on its pivots, the party bead f is removed or levered backwards
and the sashes d and i are turned horizontally inwards supported by the cords.
Obviously to close the window these actions must be reversed.
Now, the single lazy-pulley O before referred to is swivelled as above stated, and,
by being capable of thus rocking on its centre, the slight lateral play of the open-
ing window will be communicated through the cords to the said pulley wheel
which will give way to and take a direction in alignment with the cord and thus
prevent the fraying out or cutting of the edges-due to the friction of the cord on
the edges of the wheel of the cord which occurs with the ordinary fixed pulley-
wheel whenever the cord is pulled at an angle to its plane. Should however the cords
be required to be strained at an angle greater than that through which the swivel
pulley can move, I provide a second pulley or anti-friction roller beneath it to one
side, on which the cord will then take its bearing and adjust itself in alignment
as desired.
The said lazy-pulley O can be provided at the side with a pivoted roller, to further
prevent friction if required.
The lower sash d is prevented from opening beyond a pre-determined distance
by a stop on the sash which catches against the wheel of the lazy-pulley or a stop
on the frame below the pulley projecting or any other such simple convenient
means.
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. The combination with a window of the reversible type and the casement or
frame thereof, of the swivelled lazy-pulley or pulleys adapted to bear the sash
cords and turn laterally with them so as to maintain the alignment of the said
pulley or pulleys with the cords, substantially as described and illustrated.
2. The combination with a window of the reversible type and the casement or
frame thereof, of the key-operated turn-button for securing the side bead, substan-
tially as described and illustrated.

page_text: 3. The combination of reversible window, casement or frame, hoisting and
lowering tackle, and means of securing the side bead, all constructed, arranged
and operated substantially as and for the purposes described and illustrated.
Dnted the 18th day of July 1898.
