PROVISIONAL SPECIFICATION.
Improvements in Sliding and Reversible Window Sashes for Private
and Public Buildings and other Structures.
JOHN SHAW 22 Rosehill Terrace Willington-on-Tyne Northumberland Iron-
founder do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in windows, and consist of outer frame,
sliding frame, sashes pivoted to revolve verticaly or horizontaly made of wood or
other material, with suitable fastenings, racks and pinions for same.
The outer frame is provided with guides for sliding frames to slide in between
and hold them in position, and a folding or moveable sill, with space at top to
allow the sashes to ascend and descend to clear each other at the meeting bars, to
allow them to revolve when folding sill is turned over or moveable sill removed,
and one pinion on each side, with channels for draining of water.
The sliding frames are made for vertical pivoted sashes with checks, and for
borizontal pivoted sashes without checks and provided with tooth racks on each
side, to work in the tooth pinions fixed inside of outer frame.
The vertical pivoted sashes are made with checks, to correspond with those in
sliding frame, and the horizontal pivoted sashes without checks and sliding sashes
only, without cheeks also.
In my invention the sashes are connected to the sliding frames by the pivots,
and the sliding frames are connected to the outer frame by means of the tooth
racks and pinions, the bottom sash racks are one side of the pinions, and the top
sash racks on the other side of the pinions.
When ventilation is required the bottom sash is lifted up, to the required
distance, the top sash descends, the fresh air is admitted at the meeting bars, and
the impure air escapes at top.
When reversing for cleaning the bottom sash is lifted up to the top, the top sash
descends to the bottom, the folding sill is turned over to allow the sash to revolve
for cleaning, when turned back again, the bottom sash is pulled down and reversed
for cleaning, when closing again the sash is lifted up to allow the folding sill to
turn into position, then pressed down and made secure.
By this invention the whole of the window can be cleaned by the opperater, as
the top sash descends, while standing on the room floor.

and Public Buildings and other Structures.
I, JOHN SHAW 22 Rosehill Terrace Willington-on-Tyne Northumberland Iron-
founder 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 :-
My invention relates to improvements in windows, and consists of outer frame,

page_text: sliding frame, sashes pivoted to revolve vertically ar horizontally made of wood or
other material, with suitable fastenings, racks and pinions for same.
The outer frame is provided with guides F for sliding frames to slide in between,
and hold them in position, and a folding or moveable sill, and space at top to allow
the sashes to ascend to clear each other at the meeting bars to allow them to revolve,
when folding sill is turned over, or the moveable sill removed, and one concaved or
convexed wheel or pinion on each side.
The surrounding sliding frame for vertical pivoted sashes, are made with checks,
and for horizontal pivoted sashes without checks and provided with concaved or
convexed racks one on each side to work in the concaved or convexed wheels or
pinions inside of outer frame.
The vertical pivoted sashes are made with checks to correspond with those in
sliding frame, and the horizontal pivoted sashes without checks, and sliding sashes
only without checks also.
In the accompanying drawings
Fig. 1, is a horizontal section.
Fig. 2, is a vertical section.
Fig. 3, is a vertical view of racks and pinion.
In my invention the sashes are connected to the sliding frames by the
pivots G Fig. 2, and the sliding frames are connected to the outer frame by
means of the concaved and convexed racks E and pinions D. Fig. 3, the bottom
sash racks are on one side of the said pinions, and the top sash on the other.
When ventilation is required the bottom sash is lifted up to the required distance,
the top sash descends by means of the racks E and pinions D working in each
other, the fresh air is admitted at the meeting bars and the impure air escapes at
the top. When reversing for cleaning the bottom sash is lifted to the top A, the
top sash descends to the bottom, the folding sill C Fig. 2 is turned over to allow
the sash to revolve on its pivots G Fig. 2 for cleaning when the bottom sash is
lifted up into space A Fig. 2 to allow the sashes to clear each other at the meeting
bars, to allow them to revolve, when turned back, the bottom sash is drawn down
for cleaning. When closing again the sash is lifted up, to allow the sill C to turn
over, then pressed down, and made secure.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1st. The folding or moveable sill C which allows the sashes to descend to clear
each other at the meeting bars, to revolve.
2nd. The space A at top of outer frame to allow the sashes to ascend to clear
each other at the meeting bars, to revolve.
3rd. The surrounding sliding frame B which encompasses the window sashes.
4th. The concaved and convexed racks and pinions E and D.
5th. Sliding and reversible window sashes constructed substantially as described
with referance to the drawings, and operating as, and for the purpose specified.
Dated 16th day of December 1896.
