Improvements in and relating to Window Sashes.
I, THOMAS MARSHALL, of 6 McKerrell Street, Paisley, in the County of
Renfrew, Draughtsman, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in window sashes and it has for its object
to permit of ready access for cleaning the outside of the glass from the inside of the
apartment in which the window is situated.
For this purpose the lower half of the batten rod at one-side of the window 'is
hinged or secured by thumb screws to the style so that the batten rod may be
readily swung inwards or removed to permit of the window sash being turned
inwards for cleaning purposes. The batten rod at the opposite side is fitted with
hinges at two points one portion of each hinge being secured upon it, the other
portions of these hinges being adapted to be turned in against the window sash to
engage with hooks secured on the sash. These hooks enter and rest upon the lower
ends of slots in the last mentioned portions of the hinges and so practically hinge
the sash to the batten rod on this side at two points. At that side of the window
where the batten rod is hinged or secured by thumb screws the cord for suspending
the window sash has attached to its end a block which when the window is in
position to be raised or lowered engages with a hollow inclined piece secured in. a
recess in said sash, but when the window is being withdrawn a feather on this
inolined piece acts in a groove in the block to automatically push the block into a
recess piece secured in the style of the window casing and thus free the sash from
the cord so that the window sash may be swung inwards upon its hinges. A
projecting stop piece on the side of the recessed piece secured in the style of the
casing prevents the block from being withdrawn together with the window sash.
The reverse action of the block takes place when the window is being returned
to its normal position so that the window sash is then suspended from the cord.
The upper sash may be similarly fitted and the parting bead will then be made
removable to permit of the sash being swung inwards.

I THOMAS MARSHALL of No. 6 McKerrell Street Paisley in the County of
Renfrew, Draughtsman do bereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in window sashes and it has for its object
to permit of ready access for cleaning the outside of the glass from the inside of
0 the apartment.in which the window is situated, and, in order that my said invention
and the manner of performing or carrying the same into effect or practice.may be

page_text: properly understood, I have hereunto appended three explanatory sheets or
drawings, in which the same reference letters are used to indicate corresponding
parts in all the 'figures where shown.
Figure 1 on Sheet 1 is a perspective view of a sliding sash window showing
the lower sash in position ready for being swivelled into the interior of the
apartment.
Figure 2 on Sheet 2 is a similar view showing both lower & upper sash frames
swivelled within the apartment for cleaning purposes.
Figures 3 and 4 on Sheet 3 show perspective views of slotted hinge piece and
engaging hook plate.
Figure 5 on Sheet 3 is a perspective view of the cord detaching block and recess
piece, or securing housing in detached position.
Figure ou Sheet 3 is side elevation, section and plan of cord detaching
block.
Figure 7 on Sheet 3 is also a perspective view of the hollow inclined piece or
detacher.
Figure 8 on Sheet 3 is a front elevation and inverted plan of the hollow inclined
piece or detacher.
Figure 9 on Sheet 3 is a side elevation and sectional plan of recess piece
or retaining housing for securing cord detaching block when window is being
swivelled inwards.
Figures 1 and 2 of the drawings. The lower half of the batten rod B at one
Bide of the window frame is hinged on the pulley style so as to be readily swung
inwards, or it may be secured by thumb screws, and simply removed within
the apartment to permit of the sashes being swivelled or swung inside for cleaning
purposes.
The batten rod B¹ on the opposite side of the window frame has secured to
it at two places one portion a of a hinged' piece a. a' as indicated in Figure 1 and
also shown particularly in the enlarged view Figure 3.
The portion a' which has a slot a in it being adapted to be turned in against the
sash A when it is raised to the necessary position, to engage with a hook a³ fixed
by screws on the sash A and firmly secured thereto when the hook is entered and
rests upon the lower end of slot a² by the slightest lowering of sash which practically
hinges it to the batten rod indicated in this position in Figure 1, the hook piece
being shown enlarged in Figure 4.
At that side of the window frame on the pulley style where the batten rod Bris
hinged as indicated in Figure 1 and shown more particularly in Figure 2 the
appliances for detaching and securing the cords C are placed.
In reference to the lower sash A the cord for suspending same has attached to its
end a detached block C shown in enlarged views Figure 6; which when the window
sash is in position to be raised or lowered, a groove C in the block C engages with a
feather d'on a hollow inclined engaging and disengaging piece D secured in a
recess in the sash A as indicated on Figure 2, but when the window sash is being
withdrawn or swivelled to the inside of the apartment, the feather d on the hollow
inclined piece D acts on the groove C' in the detached block C to automatically
push the block into the recess piece or securing housing E which is secured in the
pulley style of the window frame, thus freeing the sash A from the cord cas
illustrated in perspective view Figure 5, so that the window sash may be swung
inwards upon its hinges.
A projecting atop piece e on the side of the recessed piece or housing E prevents
the block C from being withdrawn together with the window sash A. The reverse
action of putting the window back into its normal position causes the feather & to
act again with the groove C in block C withdrawing it from recess piece or
housing E, so that the window sash A is once more automatically attached to,
or suspended from the cordo to allow of the raising or lowering of the sash as
formerly.
The same description as above applies to the upper sash A'. The two hinged

page_text: pieces a a' however in this case being preferably attached to the side of the parting
bead on the one side of the window frame, and the parting bead from f to fl on the
other side, is made removible to permit of the sash A being swung inwards when
required.
The batten rod B may have as indicated in Figure a catch ỗ to engage with
sash A to keep it in position, the raising of the sash disengaging the catch
automatically.
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,
First. The construction or arrangement and combination of the part of fittings
for sash windows to enable them to be swivelled within apartments of buildings,
substantially as herein described in reference to, and shown in the accompanying
drawinga.
Second. The method of and means for operating the sash frames of windows so
that the cords can be detached or attached automatically from or to the sash
frames when they are to be swivelled out into the apartment, or back to their
sliding position substantially as herein described in reference to and shown in the
accompanying drawings.
Third. The forming and fitting of hinged and engaging hook pieces substantially
as herein described and shown in the accompanying drawings.
Fourth. The hollow inclined piece with engaging feather and cord detaching
and attaching block with recess piece or securing housing substantially as, and
for the purpose herein set forth and shown in the accompanying drawings.
Dated this 13th day of August 1896.
THOMAS MARSHALL.
