page_text: I, BENJAMIN WILLIAMS of Llandilo Road, Brynamman, R.S.O., Carmarthen-
shire, 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 improvements in the construction of fasteners for
windows, and the object of the invention is to provide a simple form of fastener
which will securely lock the sahes together and which will not be liable to opening
from the outside.
In carrying out my invention I screw on the meeting rail of the upper sash a
small plate having a lug or extension at the back or at the side next to the other
meeting rail. This upwardly projecting part is cut away underneath so as to
form an arm recessed at its under side, this serving as a catch to retain the part
hereinafter described. On the other meeting rail a second plate is screwed
carrying a vertical post or plate provided with a lug at its upper end. This lug
serves to carry a screwed pin provided with a head at its top and projecting at
its lower end into a perforation in the plate. On the screwed pin a small nut or

extension when the nut is turned round into locking position projects under the
arm or catch of the other plate, and on turning the screw the end will be raised
causing the extension to engage in the catch. The nut cannot be turned until
it is lowered so as to clear the projecting portion of the catch.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. 1 is a side elevation of the
improved fastener, Fig. 2 is a plan of the same, and Fig. 3 shows the catch.

fastening and unfastening being carried on in the manner above described.
To ensure the projecting arm e being turned back should it accidentally project
over the other meeting rail when the sashes are open, I form the upper edge b
of the lug and the under side of the projecting arm e with sloping surfaces ..)
that if the projection meets it, it will turn it round allowing it to pass the lug.

page_text: 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:-
_
(1) In a sash fastener, the combination with a catch on the meeting rail of the
upper sash, of a vertical screwed pin carried by a plate on the other meeting
rail, a sleeve or nut on the said pin, and a projection on the nut adapted to engage
with the catch, substantially as and for the purposes specified.
(2) In an improved sash fastener, the combination with a catch on the meeting
rail of the upper sash, of a plate on the other meeting rail, a vertical post or
standard on the same, a lug on the vertical post, a screw pin carried by the said
lug projecting into the plate, a nut on the said pin, and extension on the nut
adapted to engage with the catch substantially as and for the purposes specified.
(3) The improved sash fastener, having a catch a vertical screw and nut or
sleeve with an extension engaging in the said catch, constructed substantially as
described and shown in the accompanying drawings, and for the purposes
specified.
Dated this 17th day of June. 1897.
