We THOMAS CAUNT 225 Mansfield Road Carrington Nottingham Joiner
WILLIAM BURROWS 40 High Pavement Nottingham Printer and GEORGE
TUCKER 165 & 166 Dartmouth Street Birmingham Manufacturer do hereby
declare the nature of this invention to be as follows:-
In the first place is the centres on which the sash or casement is hung to its
frame which centre is made in two parts riveted together and on which rivet the
sash or casement is made to revolve.
One part of the said centre is made to screw on the sash or casement or to
the frame in the plane of the joint which the sash or casement makes with its
frame. The other part is made to screw on the face of the frame or sash or case-
ment.
In the second place is the means of opening and closing the windows which is
effected in the following manner. A nut and screw is mounted in a suitable carriage
which carriage is secured to the sill of the frame. And to the nut is connected
a handle or knob or any suitable means by which the nut is made to revolve and
so cause the screw to travel in one direction or the other. And the sash or
casement is connected with the said screw and made to follow in the same direction
as the screw travels.
In the third place is the connection of the top sash or casement to the bottom
sash or casement which is in the following way. A lever is pivoted within its
length to a bracket secured to one side of the frame and to one end of the lever
the bottom sash or casement is connected by a link and pin; the top sash or
casement is connected to the other end of the said lever by a similiar link
and pin.

COMPLETE SPECIFICATION.
Improvements in Fittings for Reversible Windows.
We THOMAS CAUNT of 225 Mansfield Road Carrington of the Town of Not-
tingham, Joiner and WILLIAM BURROWS of 40 High Pavement of the Town of
Nottingham, Printer and GEORGE TUCKER of 165 & 166 Dartmouth Street
Birmingham, Manufacturer 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:-
One of the main objects of our fittings is that both the sashes can be opened
by simply turning the knob of the opener, or in case of more sashes being in the
same window they all may be opened and closed in the same way for ventilation and
be disconnected for cleaning and repairs by reversing.
In the first place is the centres on which the sash & casement is hung to its
frame, which centre is made in two parts riveted together and on which rivet the
sash or casement is made to revolve one part of the said centre is made to screw on
the sash or casement in the plane of the joint which the sash or casement makes
with its frame. The other part is made to screw on the face of the frame. And
they can be fixed vice-versa."

page_text: In the second place is the means of opening and closing the sashes or casements
which is effected in the following manner.
A nut and screw is mounted in a suitable carriage which carriage is secured to
the sill of the frame, and to the nut is connected a handle or knob or any suitable
means by which the nut is made to revolve, and so cause the screw to travel in one
direction or the other, and the sash or casement is connected with the said screw
and made to follow in the same direction as the screw travels.
In the third place is the connection of the top sash or casement to the bottom
sash or casement which is in the following way. A lever is pivoted within its
length to a bracket secured to one side of the frame and to one end of the lever
the bottom sash or casement is connected by a link and pin. The top sash or
casement is connected to the other end of the said lever by a similiar link
and pin.
But our invention can be more fully described and ascertained by reference to
the drawings.
Fig. 1 represents a vertical section of a window with two sashes, hung on centres
and in an open position.
The opener is K, the connection bracket and lever is shown at B secured to the
frame F.
Fig. 2 represents the centre shown full size. A is the plate secured to the frame
in the plane of the joint of sash and frame. B is the counter part which has a
flange X overlapping the face of sash through which it is secured to the face of
sash; these two parts are riveted together and on which rivet they turn.
Fig. 3 is a horizontal section through the rivet.
Fig. 4 is a vertical section of frame shewing the centre secured thereto.
Fig. 5 is a vertical section of sash showing the centre secured on the face of
same.
Fig. 6 represents the bottom part of vertical section of window one half full
size with the sash S in a closed position. K is the knob or handle of the opener,
T is the screw, L is the carriage secured to the sill of frame through which the
nut is made to revolve by turning the knob or handle.
Fig. 7 represents a vertical section of the opener through the centre of screw T.
L is the carriage, N is the nut which forms part of the knob or handle. To one
end of screw is riveted a plate R which is secured to bottom rail of sash.
Fig. 10 represents a section through the centre of carriage L and at right angles
to the section represented in Fig. 7. The carriage is made in two parts, the part L
secured to the sill of window frame, and the part L' fixed to the other part L by
two studs or centres L" so that it may move in a circular path, for the screw to
accomodate itself to the sash in an open position as shown in Fig. 11. The nut N
is mounted in the circular part of the carriage L' and is made long enough to form
the handle or knob. It will therefore be seen that as the knob or handle is
made to revolve in one direction or the other, the sash will be opened or closed
accordingly.
Fig. 11 represents a side elevation of the carriage.
Fig. 9 represents a part plan of the meeting rails of the top and bottom
sashes in a closed position. F is the frame, Su is the top sash, S¹ is the bottom
sash.
Fig. 8 represents the meeting rails of the top and bottom sashes in an open
position. In Fig. 8 W is the bracket secured to the frame F and to which is
pivoted a lever D within its length and to one end of same the link G is pivoted,
to which is connected the bottom sash S¹ by a screw down pin O in a suitable
bracket Y. To the other end of lever D is pivoted the link U which is con-
nected to the top sash S" by a similar screw down pin V into a suitable bracket H.
The screw down pins O and V may be withdrawn to disconnect the sashes so that
they may be reversed.
The links G and U have each of them a hinge joint at P¹ and P" in Fig. 8
and 9 to allow for the sash moveing in the arc of a circle.

page_text: Likewise the carriage L of the opener is made to work on a swivel to allow of
the circular path the sash moves in as shown in Fig. 6.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare what we
claim is
First. The centre shown in Figs. 2, 3, 4, and 5 on drawing.
Second. The means of opening and closeing the sashes shown in Fig. 6 and 7 on
drawing.
Third. Is the bracket and lever connection, for connecting the sashes for opening
for ventilation as shown in Figs. 8 & 9 on drawing.
