Joiner and Builder, FREDERIOK JAMES ASTBURY of 34 Pall Mall Manchester
Chartered Accountant and WILLIAM MARTIN ECKERSLEY of 18 Grosvenor
Chambers Deansgate Manchester, Agent both in the County of Lancastor, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements which are principally designed to be
applied to casement windows, but which are also applicable in some cases to doora,
the objects of which are to make them weather-tight and also to assist in fastoning
or securing them.
For the purposes of our invention we rabbet and groove the window or door
jamb on the right hand side to receive the window or door frame which is provided
with a tongue to fit in the groove.
On the left hand side we rabbet, and form a groove or hollow in the edge of the
jamb and wo form a tongue or round on the edge of the casement or door, frame to
fit into this hollow, or the sides may be reversed-if preferred.
In the sill we form a recess preferably with a double rabbet and we groove the
bottom rail of the casement or door to close down on this double rabbet. Wo also
rabbet the jambs deeper at the top than at the bottom and we taper the sides of
the casement or door stiles accordingly so that when the door or sash is lifted out
of the recess it frees and clears itself for opening and when let down into the recess
it is drawn or forced close to the jambs thus making the casement or door weather
and dust tight. This principle can also be applied to air tight show cases book
cases wardrobe doors and so forth. In the case of double casements or doors we
also make the central stiles taper so that the casement or door frames enso
themselves in rising and become wedged tight when lowered into the recess in
the sill.
The liinges of the casements or doors are so constructed and arranged that the
latter can be raised up out of the recess in the sill or higher if required previously
to being opened or turned on the hinges in the usual way, and that when closed
they can be lowered into the said recess which will not only make them weather-
tight but also assist in securing them from being opened from the outside.
The casement or door is lifted by means of a crank lever or cam fixed to the
sill and window bottom, and a stay is also provided to regulate the opening on the
jamb.
We can also make the casement stay so as to not as a lever for raising
the casement or door out of the groove or recess in the sill, but we prefer to make
them separato as in that case tho crank lover may be used to raise the casement up
above the sill so as to give ventilation at the bottom without opening the casement
oither inwards or outwards.
On the top corner of the casement or door we fix a metal or hardwood neb to
project about half an inch and we make a corresponding uotch and groove in the
jamb to receive this neb, the neb and the groove being made on an incline or bevil
so that in closing it the top of the casement or door is drawn close to the jambs and
head or transom.
Wo rabbet the bead or transom about one inch and a half or two inches deep to
allow for the lift of the casement or door and we hinge a flap to cover this opening,
the said flap opening and falling with the movement of the casement or door and
forming a moulding on the transom. Or, we form the transom or head in two

page_text: parte, and make a loose rail between the jambs. This loose rail lifts and falls with
the casement or door and closes the gap between it and the transom, and it can,
when desired be lifted and fixed up without raising the casement or door so as to
give ventilation at the top without opening the same. Or, if preferred the moulding
or flap may be fixed onto the top of the casement or door, so as to overlap and close
the gap.
We fix a metal plate on the sill on the hinge side which when the casement or
door is opened will raise the bottom of the same clear of the top of the sill so ag
not to rub against the woodwork or paint.
The fan light above can be fixed in the same way or it may be made to open in
the ordinary manner upon hinges or pivots as usual.

COMPLETE SPECIFICATION.
Improvements in or applicable to Casement Windows and Doors.
We JOHN HARROT JONES of 86 Old Hall Road Sale in the County of Chester
Joiner and Builder, FREDERICK JAMES ASTBURY of 34 Pall Mall Manchester,
Chartered Accountant and WILLIAM MARTIN ECKERSLEY of 18 Grosvenor
Chambers Deansgate Manchester, Agent, both in the County of Lancaster, 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 improvements which are principally designed to be
applied to casement windows, but which are also applicable in some cases to dours,
the objects of which are to make them weather-tight, and also to assist in fastening
or securing them.
The nature of our said invention and the mauner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the annexed drawing is a partial elevation of a casement window
showing the application of our invention thereto, and Fig. 2 is a vertical section
and Fig. 3 a horizontal section of the same.
Figs. 5 and 6 are detached sections heroinafter more particularly referred to..
a and a¹ are the window jambs and b is the sill.
For the purposes of our invention we rebate and groove the window (or door)
jamb a on the right hand side to receive the window (or door) frame o which is
provided with a tongue c* to fit in the groove (see Fig. 3).
On the left hand side we rebate and form a groove or hollow in the edge of the
jamb a and we form a tongue or round on the edge of the casement (or door)
frame c to fit into this hollow, or the sides may be reversed if preferred.
In the sill b we form a recess (preferably with a double rebate) and we groove
the bottom rail c' of the casenient (or door) to close down on this double rebate
(see Fig. 2) and we also robato the jamb a deeper at the top than at the bottom
and we taper the side of the casement (or door) stile e accordingly (as shown by
the line on Fig. 1) so that when the sash (or door) is lifted up out of the recess
in the sill bit frees and clears itself for opening, and when let down into the recess
it is drawn or forced close to the jambs, thus making the casement (or door)
weather and dust tight.
This principle can also be applied to air-tight show cases, book cases, wardrobe
doors, and so forth.
In the case of double casements (or doors) we also make the central stiles taper

page_text: so that the casement (or door) frames enso themselves in rising and become wedged
tight when lowered into the recess in the sill.
The hinges d (Fig. 1) of the casements (or doors) are so constructed and
arranged that the latter can be raised up out of the recess in the sill b, or higher if
required, previously to being opened or turned on the hinges in the usual way, and
that when closed they can be lowered into the said recess, which will not only
make water-tight but also assist in securing them against being opened from the
outside.
The casement c (or door) is lifted by means of a crank lever or cam e fixed to
the sill and window bottom, and a stay of ordinary construction not shewn on the
drawings is also provided to regulate the opening on the jamb.
We can also make this casement stay to act as a lever for raising the casement
(or door) out of the groove or recess in the sill but we prefer to make them
separate as in that case the crank lever or came may be used to raise the casement
up above the sill to give ventilation at the bottom and in the case shown at Fig. 2
at the top also without opening the casement (or door) either inwards or outwards.
On the top corner of the casement (or door) we fix a metal or hard wood neb y to
project about half an inch and we make a corresponding notch and groove h (Figs. 1
and 2) in the jamb to receive this nob g the neb and the groove being made
slightly on an incline or bevil so that in closing it the top of the casement (or door)
is drawn close to the jamb and to the bottom rail i of the faulight, or to the head
or transon where there is no faunlight.
In cases where there is no sliding fanlight we rebate the head or transom & about
one inch and a half or two inches deep (as shown by the detached section Fig. 4)
to allow for the lift of the casement (or door) and we hiuge a flap / to covor this
opening the said flap opouing and falling with the movement of the casement
(or door) and forming a moulding on the transom.
Or, we form the transom or head in two parts (as shown by the detached section
Fig. 6) and make a loose rail * between the jambs. This loose rail * rises and
falls with the casement (or door) and closes the gap between it and the transom,
and it or the flap I can, when desired, be lifted and fixed up by inserting a pin m or
otherwise without raising the casement or door so as to give ventilation at the top
without opening the same.
Or, if preferred the moulding or flap may be permanently affixed on the top of
the casement (or door) so as to overlap and close the gap.
We fix a metal plate n (Fig. 1) on the sill on the hinge side which when the
ensement (or door) is opened will raise the bottom of the same clear of the top of
the sill so as not to rub against the woodwork or paint.
The fanlight above can be fixed for lifting in the same way, or it may be made
to open in the ordinary mannor upon hinges or pivots as usual, or it may be made
as a sliding sash (as shown at Figs. 1 and 2) or it may be made to open on the plan
described in my Letters Patent No. 14966 dated September 4th, 1801.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination with a casement window or door rising to clear the sill or
floor when opened of a double rebated sill, inclined rebate on the jamb, and rising
and falling transom substantially as, and for the purposes hereinbefore described
and illustrated by the annexed drawings.
2. The combination with a casement window or door opening as above described
of the inclined rebate on the window jamb and the inclined window stile sub-
stantially as and for the purposes hereiubefore described and illustrated by the
annexed drawings.
3. The combination with a casement, window or door opening as above described
of a rising and falling transom capable of being raised and held up for ventilation

page_text: substantially as and for the purpose hereinbefore described and illustrated by the
annexed drawings. .
