page_text: I, WILLIAM BEVAN, of the Kynoch Gun Factory, Aston Cross, Birmingham, in
the county of Warwick, Telegraph Engineer and Electrician, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the construction of a novel and simple fastener for sliding
sashes.
My improved fastener consists of a sliding bolt which passes horizontally through
the meeting rail of the bottom sash, the end of the bolt taking into the meeting rail
of the upper sash.
Any suitable catch or its equivalent is employed to keep the bolt closed.
A sash fastener of this construction is very simple, no springs are required, it
cannot be opened from the outside by means of a knife placed between the meeting
rails of the sash, and to open the fastening from the inside it is simply necessary to
release the catch and draw the bolt forward and the improved fastener can be fixed
with great facility.

α,
In the accompanying drawing figure 1 represents a front elevation of a sash
fastener constructed according to my invention applied to the meeting rails of a
sliding sash the fastener being shewn in its closed and locked position; figure 2 is
a section taken through the line A B of figure 1 the fastener being shewn in
longitudinal elevation; figure 3 is a similar view to figure 1 but shewing the catch
of the fastener in its open condition; figure 4 is a sectional view shewing the
fastener in its open position. Similar letters in all the figures represent similar parts.
a, is the sliding bolt of my sash fastener which bolt passes through and works in a
tube or sleeve b, fixed horizontally in the meeting rail c, of the bottom sash; the
bolt
is provided with a knob d, whereby it is operated and with a pin e, working in
a slot f, in the tube b, for the purpose of preventing the bolt a, from being entirely
withdrawn from the meeting rail c; the inner end of the bolt a, when the latter is
slid inwards to close the fastener takes into a tube g, fixed in the meeting rail h, of
the upper sash as shewn in figure 2; i, is the catch which I find it advantageous to
employ for retaining the bolt a, in its closed position; the said catch is pivotted at j,
to the flange k, of the tube b, and is formed with a slot 1, so that when the bolt a, is
closed as shewn in figures 1 and 2, the catch i, can be passed over a neck or reduced
portion m, of the bolt a, thereby preventing the bolt from being withdrawn ; when
however the catch i, is raised as shewn in figures 3 and 4 the bolt a, will be free to be
pulled outwards to be opened.

page_text: 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. A sash fastener consisting of a sliding bolt passing horizontally through the
meeting rail of the bottom sash the end of the bolt taking into the meeting rail of
the upper sash a suitable catch being employed to keep the bolt closed substantially
as hereinbefore described.
2. The improved sash fastener herein before described and illustrated in the accom-
panying drawing.
