Complete Specification Left, 28th Dec., 1899-Accepted, 29th Mar., 1900
I, JOHANNES STUMPF, of 22, Yorkstrasse, Berlin, Germany, Inventor, do hereby
declare the nature of this invention to be as follows:-
The present invention relates to improvements in windows and more specifically
to means whereby the upper wings of windows may be easily opened from below
and can then be let down for cleaning or other purposes.
To accomplish this I employ specially constructed hinges, having rectangularly
shaped flaps, which allow of the upper wings to be swung clear of the casement,
said hinges to be slidingly arranged upon a vertical bar secured to the side of the
window case. The two flaps of the hinges are ordinarily pressed together by
means of a spring, but when the spring is released by pulling a depending cord,
a second spring interposed between the two hinge flaps will open the hinge and
swing the wing outwards and clear of the casement.
By lifting a counterweight the opened wing can then be let down for cleaning
or repairing purposes, the hinges sliding upon the beforementioned side bar.
When the wing is pulled up again the hinges can be closed by pulling a cord and
the above referred to locking spring will then lock the hinge flaps.
For securing the wings in the closed position a locking bar is pivotted to the
vertical inner sash bar of one of wings anil can be swung from its vertical position
into a slanting or oblique one by means of a rod oscillated from below and being
clawshaped at its upper end with which it grips the the lower end of the locking
bar. When the locking bar is in the vertical position it engages two catches
secured to the window casement and prevents the upper wing or wings from being
opened, but when the locking bar is oscillated it swings out of the catches and
permits of the wing or wings being opened.
In a modification the invention is applied to the upper and lower wing or wings.
An extension of the handle bar takes into a slot provided in a pivotted plate. If
now the handle is turned their respective catches thereby locking the wing and at
the same time the upper end of the pivotted plate takes into a recess provided in
the vertical case bar of the left hand wing.
In another modification the lower wing may be locked above, below and in the
middle by arranging two oscillating locking bars one above the other which in
the middle of the wing overlap each other, the lower overlapped end of the upper
bar having a rectangularly projecting nose which upon the handle being actuated
takes into a recess provided in the left hand wing.

--
The present invention relates to improvements in windows and more specificaily
to means whereby the upper sashes of windows may be easily opened from below
and can then be let down for cleaning or other purposes.
To accomplish this I employ specially constructed hinges, having rectangularly
shaped flaps, which allow of the upper sashes to be swung clear of the casement,
said binges to be slidingly arranged upon a vertical bar secured to the side of the
window casing.
By lifting a counterweight the opened sash can then be let down for cleaning
or repairing purposes, the hinges sliding upon the beforementioned side bar.
When the sash is pulled up again the hinges can be closed by pulling a cord and
the above referred to locking spring will then lock the hinged sash.
For securing the sashes in the closed position a locking bar is pivoted to the
vertical inner sash bar of one of the sashes and can be swung from its vertical
position into a slanting or oblique one by means of a rod oscillated from below and
being clawshaped at its upper end with which it grips the lower end of the
locking bar. When the locking bar is in the vertical position it engages two
catches secured to the window casement and prevents the upper sash or sashes
from being opened, but when the locking bar is oscillated it swings out of the
catches and permits of the sash or sashes being opened.
In a modification the invention is shown applied to the upper and lower sash
or sashes. An extension of the handle bar takes into a slot provided in a
pivoted plate. If now the handle is turned their respective catches engage, thereby
locking the sash and at the same time the upper end of the pivoted plate takes
into a recess provided in the vertical case bar of the left hand sash.
In another modification the lower sash may be locked above, below and in the
middle by arranging two oscillating locking bars one above the other which in
the middle of the sash overlap each other, the lower overlapped end of the upper
har having a rectangularly projecting nose which upon the handle being actuated
takes into a recess provided in the left hand sash.
Referring to the accompanying drawings
Figure 1 shews an elevation of the device
Figure 2 a section on the line C D of Figure 1.
In the middle of the window upon the right upper window sash A thereof,
the bolt a is pivoted upon the pin b. The ends of this bolt when in the locked
position as shewn in the drawing, engage under the angle-pieces c c which are
secured to the window frame. In order to effect the unbolting of the upper
window sash the rod 9 which has above a small U-shaped fork f is pushed up
in the holdere attached to the middle of the window at the right hand lower
sash B, until the part f engages immediately underneath the angle iron c'. When
the rod g by means of its suitably shaped lower end is caused to revolve to the
right, then the right end of the fork pushes the bolt a out of the angle iron c¹
anu consequently also out of c, so that the window A is unbolted after which the
rod is again lowered. Each wing of the upper window A is secured to the
window frames by the hinges which surround the perpendicular quadrangular
guiding rod h. This rod is placed perpendicular at the side of the window open-
ing and its cylindrically formed ends are arranged to revolve in the bearings k¹
fixed to the window frame. The lower end of the rod h is provided with a handle
capable of being turned to a right angle. If it be desired to open and lower
the already unbolted window A, this handle is brought into the horizontal
position and turned 90° to the right, whereby the rod his revolved correspond-
ingly together with the hinges and the upper window A. The window A
thus open is held supported by means of a cord n connected with it and passed
over the roller m. The cord n is fastened by means of the ring t to the window
frame. When the ring is detached, the hinges operate and allow the window
to descend on the rod h, until it reaches the bearing , in which position it can

page_text: conveniently be cleaned. The raising and closing of the upper window is
effected by reversing these operations.
In double windows the inner rail (Figure 2) in order to allow the outer upper
window to be lowered must be constructed in two parts having side hinges p;
when the said parts are closed they are secured in the middle of the window by
means of a rod s fixed in the outer rail u. The free end of the said rod s possesses
a hook and passes through the overlapping ends of r r behind the said hook
the upper end of the lower window bolt a engages. The bolts may be provided
with a spring which presses out the pieces after the inner pair of windows
is opened. The rod y serves also for the bolting and unbolting of the lower
windows. For this purpose it is operated without pushing it up in the sleeve c
by simply turning it in e to the right, or to the left, by means of the handle f¹.
It thus acts upon the upper end of the bar a', which is placed so as to be capable
of sideways motion on the pivot & in the left perpendicular frame of the lower
window B. Below a¹ is a second similar bar as which rotates on the pivot b
and the upper end of this bolt passes freely into an aperture which is formed in
the lower end of the bolt a turning inwards towards the left window frame.
When the lower window is bolted the upper end of a¹ is turned beneath the
catch a fixed above the part and open towards a', whilst the lower end of a²
engages at which is open towards and the hook of fits into the suitably
arranged slot in the left window frame. When the rod g is revolved to the
right and consequently the upper part a¹ is forced out of d, the hook of a¹ is
withdrawn from the slot and at the same time the upper end of a is moved.
to the right, whereby the lower end of a² is withdrawn from . The lower
window when thus unbolted can be bolted again by turning g to the left and
thereby actuating the bolt a¹ a³ in the requisite direction.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what-
I claim is-
-
1. The improved opening and closing device for upper window casements,
characterized by the provision of a rod attached to the lower part of the window
and capable of rotation, said rod bearing a fork which operates upon the lower
end of a revoluble bolt for the said upper casement and having a vertical guide
rod whereon the said upper casement can be moved up or down on suitable hinges,
substantially as described.
2. In combination with a window casement the construction consisting
essentially of a rods passing through the overlapping portions of the hinged
pieces, and having a hooked end wherein the bolt a can engage, said bolt
engaged by the rod g when not pushed up and turned to the right, the said bolt al
being movable axially in the right lower window casement and adjusted vertically
therein, having its lower hooked-shaped end in the left lower window frame,
and a second similar bolt a placed in like manner beneath a¹ and capable of
being moved for bolting and unbolting.
3. The improved closing device for upper casements constructed and operating
substantially as described and shewn in the accompanying drawing.
