COMPLETE SPECIFICATION (AMENDED).
Improvements in and relating to Windows.
I, ARTHUR HAWLEY, of 9, Market Street, Barnsley, in the County of York,
Joiner aud Builder, 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 has reference to improvements in and relating to windows of the
kind described in the specification of my former Lettors Patent No. 13068 of 1895.
The stiles of each sash are divided vertically, the outer portions thereof being
arranged to slide within grooves in the frame, and the two portions of each stile
are pivoted together at or about the middle of their depth, the arrangement being
such that the glazed portions of the sashes can be caused to slide vertically no
matter whether the glazed portions be in a vertical or a practically horizontal
attitude. Such a construction permits of the adjustment of the sashes so as to
ensure efficient ventilation and so as to enable the window panes to be readily cleaned
from within without danger.
Referring to the accompanying drawings:
Fig. 1 is a front or inside view of a double hung sash window according to this
invention.
Fig. 2 is a section on the line a a Fig 1 and Fig. 3 a section on the line b b
Fig. 1.
Fig. 4 is an outer edge view of the inner portion of a stile of the lower sash; and
Fig. 5 a front view of the same.
Fig. 6 is a front view of the outer portion thereof, and Figs. 7 and 8 are respec-
tively inner and outer edge views of the same.
Each stile of the lower sash is formed in two parts 1 and 1ª; the parts 1, 1 slide
in grooves 2, 2 in the window frame and have pivoted to them by hinges 3, 3 the
parts 12, 1 to which the meeting rail and bottom rail are connected.
The parts 1
are of greater thickness or width below the hinges 3 than they are above and are
rabbetted or cut away along the front edge above the hinges and along the rear
edge below them, whilst the parts 1ª are of greater thickness or width above the
hinges than below them and are reversely rabbetted or cut away. The latterally
projecting portions of the parts 1 and 1ª are bevelled at 1*, (Figs. 4 to 6,) so as to
prevent rain water running through the joint. As will be seen from Fig. 2, when
he lower sash is turned about the hinges 3, the narrow lower parts of the part
tiles 1 will project outwardly through the frame, sufficient space being left to allow
he parts 1, 1 of the upper sash to pass up and down in their grooves 2.
The fastener with which the sashes are provided comprises an internally screw
hreaded tube 4 having trunnions 4" that work in bearings in a swivelling bracket 5
arried by the meeting rail of the upper sash and a thumb screw 6 that works in a
Price 871

page_text: swivelling bracket bearing 7 carried by the meeting rail of the lower sash. The
bearing 7 is such as to prevent longitudinal movement of the screw 6 but will
permit its rotary movement and limited oscillating movement in all directions.
8, 8 are bolts for securing the part stiles 1 and 12 of the upper sash together and
8, 8 are similar bolts for the lower sash.
Fig. 9 shows in vertical section a window according to this invention, the
bolts 8 being shot, the bolts 8 withdrawn and the upper sash opened for ventilation,
the fastener holding it in the desired position. The dotted lines indicate both
sashes partly opened for ventilation both the bolts 8 and 8" being withdrawn.
Fig. 10 is a similar view of the window with the lower sash opened for ventilation,
the bolts 8 being shot and the bolts 8" withdrawn.
Fig. 11 shows both sashes partly opened after the manner of ordinary sliding
sashes, the bolts 8 and 8 in this case being shot.
Fig. 12 shows both the sashes swung about their hinges, the upper one being
slidden down on to the lower one to permit its outside being easily and safely
cleaned. Both sashes may be slidden up until the part stiles 1 of the upper sash
abut against the top of the frame so as to enable furniture etc. to be readily passed
through the window.
Fig. 13 shows the lower sash swung about its hinges so that the outside may be
easily cleaned from within the room.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I desire to have it clearly
understood that I am aware that windows with vertically sliding stiles having
pivoted thereto sashes with reversely rabbeted stiles have been well known for many
years, and I do not claim that construction per se, but I declare that what I
claim is
1. In a window in which the sash stiles are divided vertically, and in which the
inner portions of such stiles are pivoted at or about the middle of their length,
rabbeting and bevelling the inner and outer portions substantially as herein before
described, and arranging the sashies so that they can be caused to slido vertically
whether the glazed portions of the sashes be in a vertical or a practically horizontal
attitude, the parts of one sash allowing space for the passage of the sliding stiles
of the other sash as described and illustrated in the accompanying drawings.
2. A sash fastener for windows of the kind herein before referred to constructed
as described and illustrated in the accompanying drawings.
