PROVISIONAL SPECIFICATION.
Improvements in and relating to Windows and their Frames.
1, DAVID YOUNGER ANNAN, of Stanley Buildings, Loons Road, Lochee, in the
County of Forfar, Scotland, Consulting Engineer, do hereby declare the nature of this
invention to be as follows:--
This invention relates to improvements in windows and their frames, the object
being to enable both sides of the window panes being cleaned from within in a simple
and expeditious manner.
In carrying out my invention I employ two detachable hinges for the lower sash,
one placed near the top and the other near the bottom of the frame. Two screws for
each hinge are inserted in one of the inside beads or "batten rods" to such a distance
that a space about equal to the thickness of the hinge leaf is left between the inside
of their heads and the bead. There are two elongated holes in the hinge leaf so
designed that it can be passed over the heads of the corresponding screws until it is
against the bead. By then pressing it down the narrower parts of the holes engage
with the screws and the hinge is secured to the bead. One screw for each hinge is
similarly inserted in the window frame and the corresponding leaf of the hinge has a
hole in it similar to those previously described but with the smaller portion on the
lower side. The cord of the balance weight which is opposite to the hinges is made
so that it can be disengaged and caught by a hook fixed in any suitable position.
When it is desired to open the window the detachable hinges are fixed to the bead,
the window frame is set so that the screws therein are brought opposite the hole in
each corresponding free leaf of the hinge and secured. The lower part of the opposite
inside bead is removed, such bead being kept in position by means of screws and
plates after the style of the detachable hinges, and the window is opened, the cord
being then detached and fixed to its hook. The lower sash is now ready for cleaning.
The upper face of the top rail of the upper sash is provided with two screws fixed so
that there is a space between the rail and the head of the screw as previously
described with reference to the screws used in connection with the detachable hinges.
The meeting rail of the lower sash is similarly provided with two screws. By
lowering the top sash until its top rail is level with the meeting rail of the lower sash
the two sets of screws are opposite one another, and the upper sash may be hung
upon the lower one by means of detachable bars, such bars having slots in their sides
so that they may be pushed below the heads of the screws. Before the upper sash is
thus supported the portion of the parting bead in contact with such top sash is
removed. When the upper sash is fixed to the lower one the two sashes are opened
and the upper sash cord is detached and fixed to its hook leaving such upper sash
hanging on the lower one and free to open.
It is to be noted that each window has to be fitted with its set of screws and that
two hinges and two bars are sufficient for all the windows of a house.
Dated this 19th day of February 1897.

Improvements in and relating to Windows and their Frames.
I, DAVID YOUNGER ANNAN, of Stanley Buildings, Lochee, in the County of Forfar,
Scotland, Consulting 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 improvements in windows and their frames, the object
being to enable both sides of the window panes being cleaned from within in a simple
and expeditious manner.
And in order that my said invention and the manner of performing or carrying the
same into effect or practice may be properly understood, I have hereunto appended
two explanatory sheets of drawings in which the same reference numerals are used to
indicate corresponding parts in all the figures where shown.
Figure 1. (Sheet 1) is an inside elevation of a window showing the detachable
hinges fixed and ready for lifting the lower sash on to them.
Figure 2. (Sheet 1) is a vertical section looking in the direction of the arrow A
(Figure 1).
Figure 3. (Sheet 2) is a vertical section looking in the direction of the arrow B.
(Figure 1).
Figure 4. (Sheet 1) is a cross-section showing the clip plates fixed to the sashes, the
parting bead and batten rod being removed.
Figure 5. (Sheet 2) is a face view of the removeable portion of the batten rod.
Figures 6. and 7. (Sheet 2) show respectively face views of the clip plates when open
and closed.
Figure 8. (Sheet 2) is an isometric view of a detachable hinge.
Figure 9. (Sheet 2) is an isometric view of the screws used in connection with the
detachable hinges.
Figures 10. and 11. (Sheet 2) are respectively a side view and a plan of the device
for securing the sash cords to the sash styles or to the window framing.
Figure 12. (Sheet 2) shows how the parting bead is hinged.
Figure 13. (Sheet 2) shows how the parting bed or the batten rod is retained in
position.
In carrying out my invention I employ two detachable hinges 20. for the lower
sash 21, one placed near the top and the other near the bottom of the sash frame.
Two screws 22. for each hinge are inserted in one of the inside beads or batten
rods" 23. to such a distance that a space about equal to the thickness of the hinge leaf
is left between the inside of their heads and the bead. There are two elongated
holes 24. in the hinge leaf so designed that it can be passed over the heads of
the corresponding screws until it is against the bead. By then pressing it down the
narrower parts of the holes engage with the screws and the hinge is secured to the
bead. One screw 25. for each hinge is similarly inserted in the window frame or sash
style 21. and the corresponding leaf of the hinge has a hole 26. in it similar to those
previously described but with the smaller portion on the lower side. The cord 27. of
the balance weight, which is opposite to the hinges, is made so that it can be
disengaged and caught by a hook fixed in any suitable position. In the drawings I
have shown a screw 28, instead of the hook, and a modified form of Fowler's Patent
No. 25253, December 29th, 1894, detachable fastener 29. When it is desired
to open the window the detachable hinges 20. are fixed to the bead 23. the window
frame is set so that the screws 25. therein are brought opposite the hole 26 in each
corresponding free leaf of the hinge and secured. The lower part of the opposite
inside bead 30. is removed; such bead being kept in position by means of the
swivelling upper part shown by the dotted lines in Figure 3. and the screws 31. and
plates 32, such plates and screws being after the style of the detachable hinges; and

page_text: the window is opened, the cord being then detached and fixed to its screw 28. The
lower sash is now ready for cleaning. The upper face of the rail of the upper sash is
provided with two screws 33. fixed so that there is a space between the rail and the
head of the screw as previously described with reference to the screws used in
connection with the detachable hinges. The meeting rail of the lower sash is
similarly provided with two screws 34. By lowering the top sash until its top rail is
level with the meeting rail of the lower sash the two sets of screws are opposite one
another as shown in Figure 3. and the upper sash may be hung upon the lower one by
means of detachable bars, or clip plates 35, such bars having slots 36. in their sides so
that they may be pushed below the heads of the screws 33. and 34. Before the upper
sash is thus supported the portion of the parting bead in contact with such top sash
is removed. This is done by opening the part 37. of such bead, as is shown by the
dotted lines in Figure 1, and then removing the lower portion 38.
When the upper
sash is fixed to the lower one the two sashes are opened and the upper sash cord is
detached and fixed to its catch leaving such upper sash hanging on the lower one and
free to open.
It is to be noted that each window has to be fitted with its set of screws and that
two hinges and two bars are sufficient for all the windows of a house.
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) In combined sliding and hinged sash windows, the use of detachable hinges
const: ucted and operating substantially as described and shown.
(2) In combination with sliding and hinged sash windows, the detachable bars or
clip plates 35. constructed and operating substantially as described and shown.
(3) In combination with sliding and hinged sash windows, the removeable batten
rod 30. constructed and operating substantially as described and shown.
(4) In combination with sliding and hinged sash windows, the improved device for
securing the sash cords to the sash styles, or to the window framing; the
improvement consisting in the use of the elongated hole which enables it to engage
with the screw 28. when the window is open and the cord detached.
(5) In combination with sliding and hinged sash windows, the use of the hinged
parting bead 37. operating substantially as described and shown.
(6) The improvements in windows, with combined sliding and hinged sashes,
consisting of the various parts hereinbefore set forth constructed and operating in
combination as described and shown.
