Improvements in Fastenings and Stays for Hinged Windows.
FREDERICK WILLIAM BAKER Architect Oakfield House Edgbaston Road
Balsall Heath Birmingham. I do hereby declare the nature of this invention to be
as follows:-
A combined casement stay, and fastener, telescopic & non telescopic curved or
straight of solid rod or hollow tubes, the one end attached by means of a knuckle
or other joint to an ordinary casement fastener tongue rivetted to a back plate or
attached to a back plate formed in two parts the back part of tongue being grooved
to receive a circular tongue upon each part of the back plate, and when in position
the back plate is rivetted together at back, so securing the tongue to the back plate
without a rivet in the ordinary way, the other end of the rod or tubing is formed
with knuckle or other joint, and buttons to fit into & slide down a slot plate screwed
to window frame, the latter slot plate serving the two purposes i.e. to receive the
tongue of the fastener when the window is closed, and the button on end of rod
or stay when the window is open in the case of telescopic fasteners the setting is
by an ordinary set pin, a split outer tube with collar, & screw pin or other
means.

Improvements in Fastenings and Stays for Hinged Windows.
I FREDERICK WILLIAM BAKER of Oakfield House, Edgbaston Road Balsall
Heath, Birmingham in the County of Worcester Architect 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 pertains to a casement or window stay or fastener or a combined
casement stay, fastener and stay holder.
Figure 1 of the accompanying drawing represents a side hinged, and outwardly
or inwardly or both moving window, or casement fitted with a combined stay and
fastener, constructed arranged and provided according to my invention.
Figure 2 represents the fastener when the window is closed, and the bar or stay
hanging down.
Figure 3 represents the side elevation of the ring end of the stay bar with knobs
on each side to fit into, and pass the circular opening in the slot plate, and slide
down same to fix the end of the stay to the window frame when the window is
opened.
Figure 4 represents the side elevation of the catch A and knuckle joint B and
back plate C.
Figure 5 represents the front of the slot plate D which receives the tongue A
when the window is closed, and also one or other of the knobs E on the ring end
when the window is stayed open by the bar or stay.
On closing the window the ring end is taken, and lifted, and the knob taken out
of the slot, when the window is drawn too, and the bar or stay is placed to hang
down the window and on opening the window the ring end is taken, the catch A is
TD 037

page_text: drawn from the slot D the window opened, and the knob E inserted into the slot,
and moved down same.
The bar or stay may be made telescopic or non-telescopic, and with set screw or
other fastening.
The application of my invention to windows, casements or frames, turning upon
hinged joints, affixed to the vertical horizontal or other sides of a frame such as
casements, fanlights skylights, single, and double windows, and the like, differs in
no essential respect from its application to a side hinged window as described, right
or left hand.
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
First. In the stay of a combined window stay, and fastener consisting of a bar or
hollow rod having knuckle joints, whereby a window can be retained open.
Secondly. In the stay of a combined window stay & fastener consisting of a bar
formed with tube the one part telescoping into the outer tube substantially as
described and set forth.
Thirdly. In a combined casement or window stay, and fastener the combination
with a bar having knuckle joints allowing the window to be affixed open, and also
allowing the said stay, and fastener to be used either for right or left hand opening
windows, substantially as described and set forth.
Dated this 17th day of April 1894.
