Improvements in Window Sashes.
I, JAMES MARTIN, of 110, Pages Walk, Old Kent Road, London, Joiner, do
hereby declare the nature of this invention to be as follows:-
This invention relates to windows in which the window sash is hinged on
one side to a loose stile and is secured on the other side to another loose stile
by bolts. The loose stiles have projections on either side which slide in rebates
in the window frame.
Two bolts are provided on the window sash, one bolt turning upwards and the
other downwards.
The bolts are slotted or hooked to engage with lock plates on the loose stile
and so draw the sash firmly against the loose stile.
I preferably use spring bolts such as are commonly known as dog cart bolts;
these are countersunk in the window sash and are operated by a key entering
into a socket in the spindle of the bolt.
When it is desired to unbolt the window a latch pivotted to one side of the
frame is turned to engage with a catch on the other side, in order to prevent
the loose stiles from moving upwards.

Improvements in window Sasnes.
I, JAMES MARTIN, of 110, Pages Walk, Old Kent Road, London, Joiner, 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 windows in which the window sash is hinged on
one side to a loose stile and is secured on the other side to another loose stile
by bolts. The loose stiles have projections on either side which slide in rebates
in the window frame.
Two bolts are provided on the window sash, one bolt turning upwards and the
other downwards.
The bolts are slotted or hooked to engage with lock plates on the loose stile
and so draw the sash firmly against the loose stile.
I preferably use spring bolts such as are commonly known as dog cart bolts;
these are countersunk in the window sash and are operated by a key entering
into a socket in the spindle of the bolt.

page_text: Figure 1 is an inside elevation of a window constructed according to this
invention, and Figures 2 and 3 are sections on the lines 2-2 and 3-3 Figure 1.
Figure 4 is an elevation (partly in section) to a larger scale of one side of the
sash with its corresponding stile.
a are the stiles suspended by cords which pass over pulleys and carry
counterbalance weights d at their ends.
e are the sashes connected to the left hand stiles by hinges f, and to the right
hand stiles by bolts g. These bolts are preferably formed as shown and engage
with lock plates h fixed to the stile.
When it is desired to unbolt the sashes to turn them on their hinges f, the
upper sash is first lowered and the latches j, pivotted at k to the frame, are
turned up and caused to engage with the catches 1. The latches j prevent the
stiles when freed from the sashes from being drawn up by the weights d.
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. The combination of the sash, the loose stile and two rotary bolts turning
in opposite directions and so formed as to draw the sash and stile together sub-
stantially as described.
2. The combination of the sash, the loose stile and the latches substantially
as described,
3. Window sashes substantially as described and illustrated in the drawings.
