Improvements in Fastenings
I, MAX PLATZER, of Tirschenreuth, Bavaria, Merchant, 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:―
The present invention relates to improvements in fastenings for swinging window
sashes and possesses considerable simplicity as regards construction and manage-
ment as compared with existing window sash fasteners.
In the accompanying drawings my improved fastening is illustrated, holding the
sash in the open position.
The improvement consists essentially in a rod (b) pivotted on a pin (a) on the
window frame (a¹), this rod being capable of sliding in a sleeve (d) pivotted to the
swinging sash (c). The said sleeve (d) which is pivotted to the pin (d') is provided

page_text: at its free end with a binding screw (d) for the purpose of enabling the rod (b) to
be made firm in the sleeve (1).
This contrivance can be arranged either above or below a window sash and may
be used for the right or left hand side.
When the swinging sash furnished with such a fastening contrivance is closed
the sleeve (d) is completely over the rod (b) and the contrivance lies parallel to the
window frame. If the sash is opened, the rod (b) is drawn out of the sleeve (d)
and when the sash has assumed the position desired it can be there secured by
simply screwing up the binding screw (d³).
From the foregoing it is clear that by the screwing up of the binding screw,
the window sash may be secured at any desired angle.
It should be mentioned that this contrivance can be so arranged that the rod (b)
may be connected with the sash and the sleeve with the window frame.
In the case of double windows the contrivance can be advantageously arranged
between the windows.
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
claim'is:-
-
A fastening for swinging window sashes characterized by a rod (b) pivoted on the
window frame (a) and capable of sliding in a sleeve () pivotted to the window
sash (c), said rod being secured in the sleeve by means of a binding screw (³) for
fastening the sash in the closed position or at any desired angle.
