Improvements in Windows and Window Cases.
WILLIAM CRUICKSHANKS 142 West Regent Street Glasgow, Sanitary
Engineer I do hereby declare the nature of this invention to be as follows:-
I. My invention consists of a new or improved method of making window
cases & sashes so as to allow of the outside glass being simply & safely got at
for cleaning or other purposes.
II. In my window case I make the inside sash stiles or channels wider than the
outside ones, that is to say, measuring accross the daylight or opening of window
case, there is a difference of width between the outside & inside stiles. The inside
stiles being therefore about ' of one inch further back than the outside ones.
III. My window case lintle is made higher in the inside channel than the outside
one, so as to allow the bottom sash to rise higher than usual when it is pushed up
from below.
IV. The window case sole is kept lower on the outside than is usual.
V. The object gained by III and IV is that when the inside sash is pushed up
to the top, and the outside sash is pulled down to the bottom, the bottom sash
(owing to the shape of the case as described in II can be pulled inwards from
the top.
VI. My window sashes are hung in the usual way-with two cords or chains on
each sash.
VII. When I use the common or ordinary sash cord I pass one end through an
eyelet hole in a metal plate, & simply tie a knot on the cord and then screw the
plate to the side of the sash below the middle of same, (oue on each side) the
timber being first hollowed out to allow the knot on the end of cord to turn
freely.
VIII. The parting beads between the sashes is only carried from the top
down the length of the top sash when shut up in position. The outside stiles
projecting past the inside stiles keeps the bottom sash wind & water tight.
IX. The batten rods for keeping the bottom sash in position are jointed at the
height of bottom sash, the top parts of rods being fixed.
X. In place of the ordinary groove for the weight cords on the sides of the
sashes I cut or half check the cord space from where the cord hangs to the outside,
so as to allow the sash to turn inwards freely.
XI. Having now described, the principal parts of my window, the working of it
is as follows, when the outside of the glass is to be got at for cleaning or any other
purpose. The catch holding each batten rod is drawn aside & the rods lifted
out. Then by simply pulling the bottom sash from the top inwards it falls flat.
The cord working as described in VII and the half check as described in X
allowing this to be done with the greatest of ease.
XII. When the glass has been cleaned or repaired as the case may be, the sash
is lifted back into its place & pushed up to the top. The top sash is now pulled
down to the bottom & pulled inward from the top lying flat in the same way as
described in XI.
XIII. The two sashes are now put into their proper position the batten rods
slipped into their places & the window is in perfect, working condition.
XIV. My claim is in the construction plan or design of the window case which

page_text: allows the sashes to be turned outside-in by simply taking of the bottom parts of
batten rods and turning the sashes inwards from the top as described in II, III
and 1V.

Improvements in Windows and Window Cases.
I, WILLIAM CRUICKSHANKS of 142 West Regent Street, Glasgow, Sanitary
Engineer, 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 window sashes and cases and it has for its object to so
construct them that the sashes can be readily and safely turned inwards for
cleaning and other purposes.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation of a window constructed in accordance with my
invention.
Fig. 2 is a vertical section of the case on the line x-x Fig. 1 showing the
sashes closed.
Fig. 3 is a vertical section of the case showing the top sash pulled down and
opened inwards for cleaning.
Fig. 4 is a sectional plan on the line y-y Fig. 1.
Figs. 5 and 6 are respectively sectional and front views of the cord retaining
plate.
Fig. 7 shows front and side views of the lower part of the batten rod.
Fig. 8 is an enlarged sectional detail.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
In carrying out my invention I make the inside sash stiles or channels, ³, of
he window case a broader or further apart than the outside ones e,, that is to say,
measuring across the daylight or opening of the wind case there is difference
of width between the inner and outer stiles (see Fig. 4). The lintel is also as
shown at Figs. 2 and 3 made with a higher or more recessed inside channel & than
the outside one el, for the purpose of allowing the bottom sash to be pushed up
higher than usual.
The window case sole is made lower on the out-ide than usual.
f
The parting beads between the sashes, only extend from the top down a short
distance below the bottom of the upper sash when it is in the shut position as
shown at Fig. 2.
The batten rods j for keeping the bottom sash in position are made in two parts
the lower parts j' being removable. These lower parts are shaped as shown in
Fig. 7, and are secured in place by means of the catches at the lower ends and
the movable buttons or latches 3 screwed or pinned to the fixed upper parts j.
The weight cords, which are the same as usual, are, preferably, secured to the
sashes by means of plates (Figs. 5 and 6) screwed to the sides of the sashes.
Each of these plates has a hole in it through which the cord is passed and tied in a
knot at the back. The side stiles of the sashes are recessed as shown in section
Fig. 5 for the reception of the knotted ends of the car. Eyelets my he
inted in the holes of the plates for the purpose of reducing frictional wear on the
at m
cords.

page_text: In lieu of the ordinary grooves in the sides of the sashes for the weight cords
I cut or half check the cord space, from the point where the cords are fixed to the
top of the sashes as shown at p Figs. 2, 3 and in enlarged sectional detail at
Fig. 8.
When it is desired to clean the outside of the window all that is necessary is to
first turn the buttons to the horizontal position shown at Figs. 2 and 3 and then
remove the lower parts of the batten rods, there ifter catch the lower sash fat
the top and pull it inwards to the position indicated in dotted lines at Fig. 2. so
that it lies flat and ready for cleaning. This sash, as it is broader than the width
or space between the outside channels e, bears, at its lower edge f', against and
turns upon them, as indicated at Fig. 2. The cords owing to the half checks p
and the arrangement of eyeletted plates allow the sash to move with ease and
freedom.
When the glass has been cleaned, the sash fis lifted back into position an!
pushed up to the top the full distance, thereafter the upper sash is pulled down as
far as it will go and then pulled inwards in the same manner as the lower sash.
The lower edge of the upper sash turns against the outer beads o as shown at
Fig. 3. Owing to the fact that the lintel e is made with the recess d and the sole
is reduced at the outside the upper sash y, when pulled down, can be made to clear
the lower edge of the sash f and be turned inwards.
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
consider novel and desire to claim is :-
Window cases constructed so that the sashes can be turned outside in by merely
removing the lower parts of the batten rods and then pulling the sashes inwards
from the top, substantially as herein before described with reference to the drawings
annexed.
