I, JOHN QUARMBY, 149, High St. Oxford Road Manchester, Agent do hereby
declare the nature of said Invention for "AN IMPROVED WINDOWSASH FASTENER
FOR RAILWAY CARRIAGES AND OTHER WINDOWS to be as follows:-
It consists of a metal lever formed at one end into an elliptical curve and pivoted
from the other end. This is fixed to any convenient part of the sash or window
frame so that the elliptical curve rests against the sash and upon any attempt to
press the window down the elliptical curve jams against the sash and firmly
secures it. To open the window the lever is lifted from the sash. For a double
sash it is fixed by means of a suitable standard upon the top of the lower sash and
rests against the side of the upper sash, it will be seen that any attempt to lift the
lower sash will be prevented equally with any attempt to pull down the upper sash.
For a railway carriage window it is fixed against the side of the frame or upon
the lower sill and rests against the window sash doing away with the ordinary
strap as it fixes the window at any height.
may attach springs to close it if convenient and also serrate or cut the elliptical
end into teeth to assist the grip if I think fit.

page_text: case may be and upon any attempt to press the window down, the elliptical curve
jams against the sash or window frame and firmly secures it. To open the window
the lever is lifted from the sash. For a double sash it is fixed by means of a
suitable standard upon the top of the lower sash and rests against the side of the
upper sash, it will be seen that any attempt to lift the lower sash will be prevented
equally with any attempt to pull down the upper sash.
For a railway carriage window it is fixed against the side of the frame or upon
the lower sill and rests against the window sash, to the lower part of the standard
is fitted a small friction wheel or block, which is pressed against the window sash
by a suitable spiral or flat spring. To the other end of the fastener lever is
attached a projection which rests against the frame of the friction wheel or against
the friction block. Upon the lever being lifted from the window the projection
presses the friction wheel or block against it, thus enabling the person opening the
window to let it down at any desired speed.
I attach springs to close it if necessary, and may cut or serrate the elliptical ends
into teeth to assist the grip if necessary.
In order that the foregoing may be better understood I send herewith a Sheet of
Drawings in which Fig. 1 represents one form attached to a double windowsash
and Fig. 2 and 3 two elevations of another attached to a railway carriage window.
In both Figs. a indicates the lever, b the elliptical end, and in Figs. 2 & 3.
c indicates the projection pressing upon the frame of friction wheel & which is kept
in position by spring e. A friction block made be substituted for friction wheel d.
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:-
1st A windowsash fastener, consisting of a pivoted lever with elleptical end
substantially as described and shown herein before and in the accompaning
drawings for the purpose set forth.
2nd A friction wheel or block in combination with a pivoted lever with elliptical
end, substantially as described and shown hereinbefore and in the accompaning
drawings for the purpose set forth.
