Improvements in Window Sashes and Casements.
I, EMANUEL GRINNALL, 39, North Street, Shrewsbury, Joiner's Foreman, do
hereby declare the nature of this invention to be as follows:-
The invention is an improved window sash & casement, so constructed that the
sashes & casements can be opened into the room, thus rendering the cleaning of
the outside perfectly easy, and absolutely free from danger. The sashes & case-
ments are made in two parts, viz.; a frame rebated, bevelled, & throated, into which
the sash is fitted with hook joints, so that it is entirely draught & water proof.
The sashes & casements are hung to the above mentioned frame at the bottom
with brass or iron butts; thus allowing them to open vertically into the room for
cleaning the outside. The sashes & casements are locked firmly into the frame
with specially made locks, fixed into the sash stiles, making it impossible for
anyone without the key, which is provided for the purpose, to tamper with the
sashes, this being a great improvement on the usual thumb screw. These sashes
& casements when not opened for cleaning, work exactly in the came manner as
the ordinary sashes & casements; & can therefore be fitted to any existing sash
or casement frames without any alteration whatever.

Improvements in Window Sashes and Casements.
I, EMANUEL GRINNALL, of 39, North Street, Shrewsbury, in the County of Salop,
Joiner's Foreman, 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 window sashes and casements,
which are constructed so that the sashes or casements can be opened into the
room or building thereby enabling the outside of the window to be cleaned from
the interior of the room or building with perfect ease and without danger. I am
also enabled to arrange the sashes so as to freely ventilate the room or building
without fear of draughts.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto two double sized sheets of drawings
upon which I have illustrated examples of my improvements.
Figure 1 is a front elevation of a window frame fitted with my improved sashes.
Figure 2 is a sectional end elevation of Figure 1.
Figure 3 is a cross sectional plan view of Figure 1 taken on the line

page_text: Figure 4 is a sectional end elevation of a window casement.
Figure 5. is a cross-sectional plan view of a window casement.
Figure 6 is a cross section shewing a portion of the sash...
Figure 7 is a front elevation of my lock for securing the sashes.
Figure 8 is a side elevation of Figure 7.
Figure 9 is a side elevation of my spring catch.
Figure 10 is a front elevation of Figure 9 a cig
In carrying my invention into practice I form the stiles or vertical pieces of
the upper and lower sash frames A and A with the additional uprights or sliding
pieces and these additional uprights are fitted to the stiles by the hook joint ba
so that the joint is absolutely draught and rain proof. I also form an additional
part at the bottom cross portion of each sash frame which is fixed to the
additional uprights 6 thus forming the loose frame B, and to this loose frame I
hinge the sashes by the butt hinges b by which meaus it will be seen that the
sashes can be opened inwardly on their hinges or reversed so as to clean the outside
of the glass or for glazing purposes as clearly shewn in dotted lines at Figure 2.
The loose frames into which the sashes fit are preferably made of hard wood such
as teak, oak or the like. In order to keep the sashes when opened inwardly at a
certain angle for ventilating purposes I provide the side bars D which are pivotted
at one end to the additional uprights, 6. The other ends of these side bars are
slotted and work upon the pivots dỉ thus enabling the sashes to be opened inwardly
and held at a certain angle as shewn at Figures 2 and 4.
In order to allow the sashes to be reversed I fix the pivot d to one end of the
springs which spring is fixed at the other end to the plate da as shewn at
Figures 9 & 10 and this plate is fixed to the sides of the sashes. It will readily be
seen that by pushing the pivots d' inwards it will release the slotted bars and allow
the sash to be reversed for cleaning and other purposes.
The sashes A and A¹ can be opened and closed in the usual manner by means of
the weights W and cords f¹ having the ordinary catch or sash fastener F for
securing them when closed. I also provide the sashes with the locks or shadbolts
L which are specially constructed for the purpose and consist of the case ¹ and
front plate having the slot 13 through which the bolt 14 shoots as shewn at
Figures 7 and 8.
This bolt is formed at one end with the shoulders which work in the round
holes formed in the sides of the case and in this end of the bolt I also form the
key hole 16.
It will be readily seen that when the key K is inserted which may be formed
as shown at Figure 11 and turned that the bolt will be forced into the case, the
spring which is pivotted at 18 being provided so as to keep the bolt in its open
or closed positions.
This lock is fitted into the sides of the sashes the key hole plate 7º being fitted
onto the front of the sashes as clearly shewn at Figure 1.
The slotted plate 10 into which the bolt shoots is fitted into the sides of the
additional uprights. Instead of using the special lock an ordinary lock may be
used for the same purpose. This special lock may be used in place of the ordinary
sash fastener and in this case I should preferably form the key T.headed.
At Figures 4 and 5 I have shewn the application of my invention to a casement
the arrangement for opening the casement either for ventilation or cleaning or
other purposes. being similar to the arrangement as hereinbefore described in
connection with sashes.
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:-
CLAIMS.

purpose substantially as herein set forth and as shewn upon the drawings.
Fourth-In window sashes and casements the use of the lock or shadbolt such
as L either for securing the sashes or casement to the loose frame B or for securing
