PROVISIONAL SPECIFICATION.
Improvements in and relating to Reversible Windows.
We JOHN LUMLEY Builders Foreman 9 Haywray Street Harrogate Yorkshire
THOMAS LINSKILL Builder & Timber Merchant Mowbray House, Harrogate,
Yorkshire do hereby declare the nature of this invention to be as follows:
:-
This invention relates to improvements in reversible windows such as are fitted in
fixed frames and to those which are made reversible within a frame the side stiles
of which are made to slide up or down in guides and ballanced with weights or any
other appliance, and made to reverse for the convenience of cleaning glazing or
painting from the inside. It can be applied to windows which slide up and down
such as are now in use but do not reverse.
Our improvements consists in the special construction of the meeting faces of the
sash and hanging stiles, which are formed of plates of any suitable metal shaped
to form rebates or weather guards by locking together the one within the other.
By forming the meeting stiles and rebates with metal plates there is no sticking
by the capillary attraction of moisture as in the case of a wood joint.
For sashes which slide up or down in guides we use a center or pivot the center
of which is within the face of the sash and the stiles are rebated beyond the center
of the pivot to allow the sash to be completly reversed.
For a reversible sash in a fixed frame we use what is commonly known as
a back lap hingh or a pivot the center of which is in line with the face of the
sash stile.
We employ special catches to secure the sashes temporaly in any position
required and latches for securing the sashes when closed.

COMPLETE SPECIFICATION.
Improvements in and relating to Reversible Windows.
We JOHN LUMLEY No. 9 Haywra Street Harrogate in the County of York,
Builders Foreman and THOMAS LINSKILL Mowbray House, Harrogate in the
County of York Builder, 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 in reversible window sashes such as are
fitted in fixed frames and to those which are made reversible within a frame the side
stiles of which are made to slide up or down in guides and balanced with weights or
any other appliance, and made to reverse for the convenience of cleaning, glazing
or painting from the inside.
Our improvements consists in the construction of the meeting stiles to which we
fix weather bars made of any suitable metal these form the rebates by locking
together one within the other forming a complete weather guard in forming rebates
by metal plates there is no sticking by the capillary attraction of moisture as in the
case where wood joins wood.
For sashes which slide up or down in groves we use a center or pivot the center
of which is within the face of the sash stile, and the face of the weather bars

page_text: are fixed in line with the center of the pivot to allow the sash to be completely
reversed.
For a reversible sash in a fixed frame we use what is commonly known as a back
lap hinge formed to suit the sash and hanging stiles and is fixed in line with the
face of the stiles.
We use special catches and fastenings to secure the sash temporal in any position
and latches and fastenings to secure the same when closed.
The weather bars can be readily applied to existing sashes and made to reverse
in the same manner as new ones.
In the accompanying drawings the reference letters in each drawing represent the
same parts.
Fig. 1 is a full sized part elevation showing the weather bars sash and hanging
stiles hinged together Ċ the sash stile D the hanging stile and A A the metal
weather bars E the hinge.
Fig. 2. is a section of Fig. 1 below the center or hinge. This shows the position
of the weather bars when closed C the sash stile D the hanging stile and A B the
weather bars.
Fig. 3 is the same section showing the sash partly open.
Fig. 4 is a section of Fig. 1 above the hinge or center and
Fig. 5 is the same section partly open.
Fig. 6. is a part elevation of a sash and hanging stiles when a center or pivot is
used which has no projecting knuckle but is flush with the face of the stiles the
center of the pivot is within and the weather bars are set back to this center
to allow the sash to be completely reversed C the sash stile D hanging stile
A A weather bars H the hinge.
Fig. 7. is a section of Fig. 6 showing the sash closed and
Fig. 8. is another section of the same showing the sash partly open.
Fig. 9. is a plan and Fig. 10 a section of the hinge pivot or centre shown at H
Fig. 6.
cc. is a rivet which binds the two parts of the said hinge together. d. d. the
center or bearing part of the pivot upon which the parts revolve. A shows the
curved and B B the straight parts of the metal plates or weather bars of which the
hinge or pivot forms a part. This form of hinge is fixed to the inside of the sash
and hanging stiles, within the face of the stile as shown, the knuckle or part H only
is flush see Fig. 9.
Fig. 11 is another form of hinge which is outlined upon Fig. 6 by dotted lines.
This hinge is fixed upon the face of the sash and hanging stiles.
Fig. 12. is a section of Fig. 11 c c the rivet which binds the parts together
d. d. the centre upon which the parts revolve and shown by dotted lines. A shows
the curved and B B the straight parts of the metal weather bars which are fixed
within the face of the stiles as shown.
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
1st. In the construction of sashes and sash frames to carry the former in a manner
to be reversible by turning upon a horizontal axis. The formation of the metal
weather bars fixed between the sash and hanging stiles substantialy as shown by
the drawings and for the purpose set forth and described.
2nd. In eashes carried in window frames made reversible by turning upon a
horizontal axis centrally situated, by the employment of a hinge, pivot, or center
constructed to suit the weather bars and which allows the sash to be closed verticaly
outside or reversed to a vertical position inside.
