Improvements in Fastenings for Windows and the like.
1 JOSEPH CHAFFER of Mount Pleasant Chapeltown Sheffield in the County of
York Store Keeper 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 fastenings for window sashes the object being to so
construct and arrange the fastening that it may by simple mechanical means force
the sashes apart so as to more securely press them against the window frame and
prevent them from rattling to attain which I construct and arrange my said
improved fastening substantially as set forth in the accompanying sheet of drawings
in which
Fig. 1 is a perspective view of my improved fastening showing the same securing
the sashes together and in a position for preventing the rattling thereof.
Fig. 2 is a front elevation and
Fig. 3 is a plan of said fastening.
Like letters of reference denote corresponding parts in each view.
The bolt. A has a wedge formed concentric projection a¹ formed thereon and the
said bolt A works in a barrel B which is fixed on the lower sash C when the
sashes C and D are closed as shown the end portion a² of the bolt A may be forced
into an eye or staple fixed on the upper sash D.
The bolt A may be made with a lever head a³ or an ordinary thumb and finger
head as shown in dotted lines Fig. 3.
After the sashes C and D are met and the bolt A forced so that its end a² enters
the eye or staple d' the lever head a³ is turned to the right and the thinner end of the
wedge shaped projection a' begins to press the sashes C and D or sash fastener
fittings Band d thereby pressing the said sashes apart and effectually preventing
thereby the rattling or shaking of the window.
To withdraw the bolt A from the eye or staple d' it is necessary to turn the
head a³ to the left so as to remove the wedge shaped projection a¹ from between
the sashes, and in withdrawing the bolt A the said projection travels along the gap
or cut away part of the barrel B.
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 a sash fastener the use of bolt A formed with a concentric wedge shaped

page_text: projection a¹ and working in a barrel B substantially as described and used for the
purpose specified.
