Improvements in Means for Opening and Closing Window Casements
and the like.
1, CHARLES WILLIAM HANCOCK, 31, Swindon Street, Cheltenham, Casement
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved device for opening and closing case-
ments, skylights, or window frames and the like, and has special reference
to hinged casements or windows opening outwards.
The object of this invention is to obviate the inconvenience and objection arising
from the quadrant bracket or stay at present in use, and which when the case-
ment or window is closed, is apt to project beyond the window or casement
frame inwardly, and come in the way of blinds, curtains or other provisions on
the inside of the window frames, and also to provide a means for opening and
closing casements of this kind at any height they may be fixed.
In order to carry out this invention 1 provide a vertical rod of a convenient
size or diameter, of the length of the vertical height of the casement or window
or thereabouts, and fixed either to the window frame at the top and bottom, or
to the casement as may be convenient.
I provide a sliding sleeve or socket, which slides up and down this said vertical
rod a required distance to regulate the amount of opening, the bottom and length
of the stroke of this sliding sleeve being fixed by an adjustable collar or ring on
the aforesaid vertical rod.
Attached to this said sleeve or socket is a pivotted lever or connecting stay,
the other end of which is also pivotted to the bottom of the hinged casement.
Cords are attached to the said sliding sleeve, and to the end of the lever or
connecting stay aforesaid, where it is pivotted to the casement, for opening and
closing the said casement.
In opening the casement it is only necessary to pull the cord attached to the
sliding sleeve aforesaid, and so pull the said sliding sleeve downwards, when
the connecting stay or lever aforesaid is pushed outwards, and so opens the
casement to any angle required.
The cords pass over pulleys fitted in frames attached to the vertical rod herein-
before mentioned.
The casement is closed either by its own weight, or by pulling down the cord
attached to the end of the connecting stay aforesaid.
In the event of the casement requiring to be opened to such an extent that the
connecting lever or stay is brought out to a position at or near a right angle to
that of the vertical rod aforesaid, it is obvious that owing to the "dead centre"
position of the sliding sleeve on the vertical rod, the casement could not be
closed by pulling the cord attached to the lower part of the casement and con-

page_text: necting stay, and I therefore provide a pulley revolving at the upper part of the
vertical rod aforesaid, and fixed above the aforesaid sleeve, and a cord passing
over this pulley is attached to the said sleeve, so that by pulling the cord down-
wards, the said sleeve is pulled upwards, and the angular position of the con-
necting stay relatively to the vertical rod is reduced and the casement can be
closed.
For casements that are fixed in positions within reach of the hand and
therefore not requiring to be opened or closed by means of cords, I provide the
sliding sleeve with a spring catch arranged to grip the rod, and that can be
released by the pressure of the thumb or finger, and the aforesaid sleeve can be
raised or lowered by the hand direct, instead of by cords.
By a slight modification this invention can also be applied to horizontally
hinged or door casements or windows.

COMPLETE SPECIFICATION.
Improvements in Means for Opening and Closing Window Casements
and the like.
I, CHARLES WILLIAM HANCOCK, 31, Swindon Street, Cheltenham, Casement
Maker, 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 an improved device for opening and closing case-
ments, skylights, or window frames and the like, and has special reference
to hinged casements or windows opening outwards.
The object of this invention is to obviate the inconvenience and objection arising
from the quadrant bracket or stay at present in use, and which when the case-
ment or window is closed, is apt to project beyond the window or casement
frame inwardly, and come in the way of blinds, curtains, or other provisions on
the inside of the window frames, and also to provide a means for opening and
closing casements of this kind at any height they may be fixed.
In order to carry out this invention, I provide a vertical rod of a convenient
size or diameter, of the length of the vertical height of the casement or window
or thereabouts, and fixed either to the window frame at the top and bottom, or
to the casement as may be convenient.
I provide a sliding sleeve or socket, which slides up and down this said vertical
rod a required distance to regulate the amount of opening, the bottom and length
of the stroke of this sliding sleeve being fixed by an adjustable collar or ring on
the aforesaid vertical rod.
Attached to this said sleeve or socket is a pivotted lever or connecting stay,
the other end of which is also pivotted to the bottom of the hinged casement.
Cords are attached to the said sliding sleeve, and to the end of the lever or
connecting stay aforesaid, where it is pivotted to the casement, for opening and
closing the said casement.
In opening the casement it is only necessary to pull the cord attached to the
sliding sleeve aforesaid, and so pull the said sliding sleeve downwards, when

page_text: the connecting stay or lever aforesaid is pushed outwards and thus opens the
casement to any angle required.
The cords pass over pulleys fitted in frames attached to the vertical rod herein-
before mentioned.
The casement is closed either by its own weight, or by pulling down the cord
attached to the end of the connecting stay aforesaid.
"
"
In the event of the casement requiring to be opened to such an extent that the
connecting lever or stay is brought out to a position at or near a right angle to
that of the vertical rod aforesaid, it is obvious that owing to the dead centre
position of the sliding sleeve on the vertical rod, the casement could not be
closed by pulling the cord attached to the lower part of the casement and con-
necting stay, and I therefore provide a pulley revolving at the upper part of the
vertical rod aforesaid, and fixed above the aforesaid sleeve, and a cord passing
over this pulley is attached to the said sleeve, so that by pulling the cord down-
ward, the said sleeve is pulled upwards, and the angular position of the con-
necting stay relatively to the vertical rod is reduced and the casement can be
closed.
For casements that are fixed in positions within the reach of the hand and
therefore not requiring to be opened or closed by means of cords, I provide the
sliding sleeve with a spring catch arranged to grip the rod, and that can be
released by the pressure of the thumb or finger, and the aforesaid sleeve can be
raised or lowered by the hand direct, instead of by cords.
This arrangement however may be modified by any other alternative device
as may be convenient to the special requirement of the particular casement.
By a slight modification this invention can also be applied to horizontally
hinged or "door" casements or windows.
In order that this invention may be readily understood, reference is made to
the accompanying drawings in which Fig. 1 represents an elevation of the
improved casement opener, the casement being shewn in section; Fig. 2 an end
elevation of the bottom pulley of the said casement opener; Fig. 3, a plan of the
sliding socket.
In these several views, A. is the casement frame, B the hinged casement hung
at the hinge C, the dotted lines shewing the casement in opening position, D is
the vertical rod, attached to the casement frame by top and bottom brackets E
& E F is the sliding socket, G the connecting bar or rod attached at its upper
end to the sliding socket F, and at its lower end by means of the bracket arm H,
to the casement to be opened. I is an adjustable stop to regulate the amount of
opening required, the momentum of the opening and shutting of the casement
being gradually reduced and deadened by an indiarubber ring as shewn at J, or
small coil spring as at K, or any other convenient means may be adopted for
checking or preventing the slam of the casement in opening or shutting. A
cord N is attached, one end to the sliding socket F through the eye L, and the
other end to an eye in the bracket arm H, (or the cord may be in separate lengths)
passing over the pulley M fixed to the lower end of the vertical rod 1). By pulling
down this cord N, the casement can be opened to any required amount.
In the case of the connecting bar or rod G being brought out to a level or
horizontal condition, and a dead centre" position taking place, a small pulley ()
(shewn in dotted lines) can be fixed to the top bracket E, over which a small
cord is passed, attached at one end to the socket F, the other end being for
pulling the said socket upwards, when the "dead centre" position is altered and
the casement closed in the ordinary way.
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. In window casements and the like, the provision of a device for opening

page_text: the same, substantially as, and for the purpose herein set forth and described
and illustrated by the accompanying drawings.
2. The application of this invention to any form or kind of casement, skylight,
window frame, and the like, substantially as and for the purpose herein set forth
and described and illustrated by the accompanying drawings.
Dated this 3rd day of July 1899.
