Improvements in Window Sashes.
I, JOHN WALKER, of 7, Gladstone Place, Main Street, Shettleston, in the
County of Lanark, Foreman Slater, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to window sashes and has for its object to so construct.
these that the window can with ease be cleaned from the inside of the room.
The window consists as usual of a top and bottom sash and the sashes are each
made in two portions (one portion fitting within the other), the joint between
which is cut so as to be weather proof. The joint is formed by interlocking.
or abutting edges, but in the case of the side joints a vertically extending space
is left between these edges at a particular point, so that any rain blown in so
far and adhering by capillary attraction may drop freely to the window sill.
The inner portion of the sash is brought in for cleaning purposes by turning it
upon a hinge at the lower end, the said hinge being also fixed to the outer portion
of the sash, which latter portion has only a sliding action. In the case of the
top sash of the window the hinge is so arranged that it can be brought in until
it is in line with the bottom sash. The sashes are raised and lowered in the
usual manner by ropes and weights, and suitable catches secure the aforesaid
inner sashes to the outer sashes, when they are closed and small handles are
provided to enable them to be opened.
I, JOHN WALKER, of 7, Gladstone Place, Main Street, Shettleston, near
Glasgow, in the County of Lanark, Foreman Slater, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to window sashes and has for its object to so construct
these that the window can with ease be cleaned from the inside of the room..

represents a vertical transverse section, showing the upper sash of window in
its closed and bottom sash in its open position. Fig. 3 is a sectional plan taken

securing the opening frame to the sliding portion.
The window consists as usual of a top sash A and bottom sash B and the
sashes A, B, are each made in two portions, A, A, B, B', (one portion fitting
within the other), the joint between which is cut, as shown at Figs. 2 and 3, so as
to be weather proof. The joint is formed by interlocking or abutting edges, but
in the case of the side joints a vertically extending space C is left between these
edges at a particular point, so that any rain blown in so far and adhering by
capillary attraction may drop freely to the window sill. The inner portions A,
B; of the sashes are brought in for cleaning purposes by turning them upon
hinges D at their lower ends, the said hinges being also fixed to the outer por-
tions A, B, of the sashes, which latter portions have only a sliding action.
The hinge employed consists preferably of three portions D, D1, D2, of metal
jointed together, the exact form of this hinge and its position, in two different
positions of the window sashes, being shown at Fig. 2. The part D is secured to
the portion of the sash constantly retained within the usual sliding groove, and
the part I to the opening sash, whilst the portion D extends between and con-
nects these.
Whilst a hinge of the form shown and described is preferably employed,
because of its suitability under any circumstances, it is obvious that in the case
of a kitchen window, which is ordinarily provided with a broad sill, a hinge of
the same nature but with only two portions, is equally applicable, as the lower
sash when brought in for cleaning purposes rests upon the sill, and the upper
sash thereafter is brought to rest on the opened lower sash.
As a modification the top cross bar of the outer portion A' of the top sash A
may be dispensed with entirely, and the sides A' of this outer portion be run
upwards the necessary distance into the top cross groove E. In such a case when
the upper sash A is to be drawn inwards for cleaning purposes, it is first neces-
sary to lower it, in order that it may be within reach when the lower sash B is
drawn inwards. The lower sash B is then drawn inwards and the upper sash A
now within reach of the operator, is drawn through between the sliding frames B¹
of the lower sash B, the sliding frames B being at such distance apart as shown
at Fig. 3, as to admit of this being done.
Or as an alternative, the cross portion of the top sash A may be secured in the
top cross groove E so as to permit the sash to be withdrawn without lowering
the window. By these three methods all known exigencies are met and the
invention is rendered equally applicable to all new or old forms of windows
without alteration thereon, whether provided with Venetian blinds or ordinary
blinds.
The sashes may be spring locked by catches constructed as shown at Figs. 1, 3,
and 4, or in any ordinary manner to the sides of their outer frames, finger
catches being provided for the purpose of withdrawing the lock, and which also
Berves to open the window sashi.
The catches or fasteners consist preferably of three pieces P1, P2, P3, of any
suitable material, P" being a spring piece fixed to the upper horizontal portion
of the opening sash and 13 fixed (vertically) to the sliding portion of said sash
in such a position as to engage the former when the sash is in its normal or
closed position, whilst P² merely serves as a finger catch with which to draw in
the sash, and also as a cover to hide the recess made to admit of the depression
of the spring piece P¹. The spring piece PI has a projection which engages with
a hole or slot in the piece P³ to effect the locking.
In order to open the sash the horizontal spring piece P1 is depressed by the
operator, which action frees it from the vertical locking piece P³ and admits of
the sash being drawn in for cleaning or other purposes.
The sashes A, B, are raised and lowered in the usual manner, and because of
their connection to the outer portions A¹, B1, are balanced by weights attached
to these cuter portions by cords.

page_text: 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
1
1. Window sashes adapted to open inward for cleaning purposes having
outer or side frames or sliding portions moving in the ordinary grooves, to
which sliding portions the opening sashes are normally locked, the abutting
edges of said sashes and sliding frames being formed in such wise as to consti-
tute weather proof joints, and to which sliding frames the sashes are hinged at
their lower ends, substantially in the manner described.
2. In window sashes adapted to open inward for cleaning purposes, a hinge
of the form described having two or three portions, substantially as and for the..
purpose set forth.
