COMPLETE SPECIFICATION.
Improvements in and relating to Sliding Window Sashes, Casements,
and the like.
I, ALFRED WATSON, of 6, Maidstone Street, Bradford, in the County of York,
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:-
This invention relates to certain improvements in the construction of sliding
window sashes, casements, analogous frames and the like, by arranging them in
such a manner that, the sashes or the like may be moved up and down in the
frames, and in addition opened somewhat in the same manner as a hinged door
into the room, thereby facilitating the operation of cleaning, painting or glazing
by making it unnecessary to have to approach the sash or the like from the out-
side; and thereby reduce the liability of accidents due to cleaning and the like
with windows arranged as is now the common practice.
In describing my invention in detail, reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents the elevation of a portion of a window.
frame arranged according to my invention.
Fig. 2 is a plan of same showing portions of the upper and lower sashes of a
window.
Fig. 3 is a detached detail of a portion of what I term a slotted plate or bar
forming part of the hinge.
.
Fig. 4 is another view of the same looking at right angles to that shown by
Fig. 3.
Fig. 5 is an elevation of a winged bar forming part of the hinge of a sash frame
or the like; the remaining figures being sectional views of slotted plates or bars of
various configurations showing the slits for the hinge wings in various positions.
In all the figures similar parts are indicated by similar letters where they appear.
The top and bottom window sashes A and B may be balanced with cords and
weights attached to one or both sides in any convenient manner; when attached to
both sides, facilities for detaching the sash cords on the opening side of the sash
are provided, the cords and weights W on the hinged side of the sash remaining
connected. On this side of the window frame, to the pulley stile C I secure a
hollow slotted plate or bar for each window sash, bar D for the bottom sash, and
bar D for the top sash, each plate or bar extending by preference the full length
of the pulley stile C of the window frame, and each plate or bar is provided with
notches E cut therein at convenient places.
A circular rod F is placed into the centre hole or hollow of each slotted plate
or bar D and D¹ and each circular rod F is arranged with a number of wings G
in convenient places, the distance between them and the width corresponding
with the notches E cut in the before mentioned slotted plates or bars, which are
also provided with a slit or slot hole H extending the full length of the same.
The wings G of the respective circular rods F are screwed to the window
sashes A and B and when the sashes are in the position for sliding, the wings

page_text: engage with the respective slits or slot holes H, thus allowing the sashes to be
moved up or down.
The window frames are provided with staff beads J and in order to open the
window sashes A and B into the room, the staff beads J may be hinged to the
window frame in a manner so as to be opened back clear of the window sash, thus
liberating the bottom sliding sash B which when moved into the position so that
the wings G are opposite the notches E, the sash B may then be turned backwards
into the room, the wings G passing into the notches, thus forming a hinge on
which the window sash is swung; the same remarks as regards the notches in
slotted plate or bar D¹ and the position of the wings G on rod F placed in the said
plate or bar, apply to the top sash A; thus when opened in the manner described,
giving facilities for cleaning and the like without a person having to sit or stand
outside the window.
The centre slotted plate or bar D¹ may be secured to the pulley stile C as shown,
in which case it acts as a parting bead on that side of the sash, the parting bead
on the opposite side being arranged for removal clear of the sash in any convenient
manner.
One or both of the slotted plates or bars D and D' may if desired be morticed
into the pulley stile C or the outer bar D may be secured to the staff bead J which
in this case will have to be securely fixed to the window frame and the sliding
sash grooved to correspond; or the said slotted plate may be provided with flanges
for securing the plate; or the contour may be otherwise altered to any convenient
shape for attaching the plate in the position required, providing the slot hole H
is in the proper position for receiving the wings G of rod F and notches E cut,
in order that the sash or the like may be opened when the position of the wings
and notches are opposite to each other.
The foregoing description relates to windows, but it will be readily understood,
that the invention is equally applicable to sliding doors or the like, and may be
applied to either wood or metal casements of various sections.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
-
Sliding sashes or the like with which are combined winged bars engaging with
hollow slotted plates or bars notched and arranged substantially in the manner
and for the purpose as herein before set forth.
Dated this 17th day of December 1897.
