Improvements in and relating to Reversible Windows:
RICHARD MASON, Joiner &c., Window Works, Hemsworth, near Wakefield,
Yorkshire, do hereby declare the nature of this invention to be as follows:-
1st. A pivot with case or hinge, the pivot to go through the knuckle of case
or hinge, with screw on the inner end to screw into frame stile, with or without
a small collar let in, and screwed to frame stile. The outer end the shape of
an ordinary wood-screw. The pivot can be made hollow with thread on the
inside to receive a thumbscrew, made to tighten on the case end, to fix the
sash at any angle.
The pivot case or hinges are let in and screwed on to sashes and frames, or on
either seperately.
2nd. A window screw fixed on meeting rail of bottom sash, on a knuckle joint
at the front end.
A stud with hole through on the underside of barrel to fall into a boss with
a bolt attachment. The bolt sliding through the hole in stud, and securing the
screw to top sash, which arrangement makes it easy to secure or release the
sashes.
3rd. The frame head to be constructed on the bevel from the outside lining
upward so as to admit the air more freely.
4th. Two screens of gauze, wire, canvas, or other suitable material, one to be
fixed on the meeting bars of sashes, the other fixed to the window frame head
falling against the top rail of the top sash, for the purpose of arresting the
dust, and other impurities from entering the building when the window is open
for ventilation.

Improvements in and relating to Reversible Windows.
I, RICHARD MASON, Window Works, Hemsworth, near Wakefield, in the County
of York, Joiner, etc., do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
My invention has for its object improvements in the construction of reversible
windows by which I obtain a better ventilation and also prevent dust or other
impurities from entering the building when the window is partially opened
or for ventilation purposes only.

page_text: In order that my invention may be more clearly understood and easily carried
into practical effect I have appended hercunto two double sized sheets of drawings
upon which I have illustrated examples of my reversible windows...
Figure 1 is a front view of a window sash and frame constructed according to
my invention.
Figure 2 is a sectional side elevation of Figure 1.
Figure 3 is a similar view to Figure 2 shewing the sashes open.
Figure 4 is a front view shewing a modified form of my window.
Figure 5 is a sectional side elevation of Figure 4 shewing the top sash open.
Figure 6 is an enlarged end elevation of my device for securing the sashes
together when closed.

Figure 7 is a plan view of Figure 6.
Figure 8 is a detached plan view of the sliding bolt and socket or boss which
is fixed to the meeting rail of top sash.

Figure 9. is a plan view, of the socket in which the sashes are pivoted.
Figure 10 is a side view of Figure, 9.
In carrying my invention into practice I mount the sashes A and B centrally
upon the pivots a¹ and b¹ which pivots pass through or work in the sockets
or cases and 62 secured centrally to either side of the sashes. These sockets,
cases, or hinges, are preferably formed by suitable tools from sheet metal and
the lower half-of the base is cut away as clearly shewn at Figure 9 so as to
allow the sashes to freely swing on their pivots. The pivots a¹ and b¹ are formed
with a screw thread on their inner ends to screw into the frame stile or into a
collar or socket-piece let therein. The outer ends of these pivots are preferably.
formed the shape of an ordinary screw or they may be made hollow and tapped
to receive a thumb screw for tightening onto the ends of the sockets a² and b²
so as to fix the sashes at any angle desired.
Fixed to the meeting rail 6 of the lower sash B is the hinge plate D pivoted
or hinged at de to the saddle which carries or supports the window screw or
fastening E or the saddle d³ may be hinged or pivoted to the meeting rail. This
screw or fastening E which is free to revolve in the saddle socket forming
part. of or fixed to the saddle and kept in position by the collar e¹ screws
into the barrel or sleeve F which is tapped for that purpose. Formed on or
attached to the other end of this barrel or sleeve is the block lug or projection fl
having the hole f formed therein and this lug or projection fits into the slot
or recess formed in the socket piece or boss H which is fixed to the meeting
rail of the upper sash A as clearly shewn at Figures 2, 3, 5, 6, and 7. The
sliding bolt h which works in a hole formed in the part h³ of the boss H fits into
the hole of the lug f' and is provided for the purpose of securing the end
of the barrel or sleeve F to the boss H as clearly shewn at Figures 2, 6 and 7
by which means the two sashes are firmly held together when closed and easily
released.
It will be seen that the sashes may be opened to any angle by withdrawing
the bolt 2 out of the hole for by unscrewing the screw E out of the sleeve F.
Or the sashes may be safely left slightly open by partially unscrewing the

closed..
The head of the casement or frame J is formed on the bevel or incline-
that is sloping from the inside outwards so as to admit air more freely as
clearly shewn at Figures 2, 3 and 5 and pivoted to the head of the frame whether
inclined or so as to lie flush against the top rail of the upper sash is the
screen K made of fine wire gauze canvas, or other suitable material, so that when
the top sash is only partially open the lower edge of this screen rests against
the edge of the top rail and arrests or prevents dust or other impurities from
entering,. The cord or chain which passes over the pulley. ² fixed to the
side or other convenient part of the frame is provided for the purpose of lifting
up the screen out of the way when closing the upper sash after it has been

page_text: opened beyond a certain limit. Also fixed to one of the meeting bars a² or 6³
is the screen L similar to the screen K so that dust and other impurities are
prevented from entering between these bars when the sashes are partially
opened. Or a screen may be attached to both meeting bars a b³.
At Figures 4 and 5 I have shewn my window with the bottom sash B made
to slide up and down by means of the cords and weights W in the usual manner
the upper sash A being pivoted so as to open in the same manner as previously
described. Or the sash A may be made to slide and the sash B pivoted. It will
be seen that when the bolt he has been withdrawn the fastening E and sleeve F
can be moved into the position as shewn at Figure 5 and in dotted lines as
shewn at Figure 6 thus enabling either sash to be opened without opening the
other sash. Sliding bolts may be fixed to the bottom meeting rail for fastening
the sash up if desired.
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:
-
CLAIMS.
First The improvements in reversible windows the pivot screws a¹ and b
and sockets a² and 62 whether used with a collar or not and either with or without
the thumb screw end to the screw substantially as herein set forth and
illustrated.
Second: In improvements in reversible windows the meeting rail fastening
consisting of a saddle socket hinged to the plate or the meeting rail the screw
turning in the socket with the barrel and screw capable of turning upon the
said pivot and also carrying a block fl at its outer end for engagement with
the plate II and the sliding blade 2 substantially as herein set forth and
shewn upon the accompanying drawings.
Third-In improvements in reversible windows bevelling the frame head as
shewn at Figures 2, 3 and 5 substantially for the purpose herein set forth.
Fourth: The improvements in reversible windows attaching gauze wire or
its equivalent to the head of the frame and the meeting rail either top or
bottom or both substantially as herein set forth and as shewn upon the
