Improved Fastener for Doors, Windows, Boxes, and the like,

1 JOHN ABBOTT PICCAVER of 2 Newland Chambers, Northampton, in the
County of Northampton, Architect and Surveyor, do hereby declare the nature of
this invention to be as follows and the object of it is to provide a fastener for
window sashes and the like that shall be more economical, simple and effective than
those in general use.
On the meeting rail or bar of one window sash I secure by pins, screws or
otherwise a metal plate carrying a staple or loop through which has been passed a
link of suitable shape and size, say of an oval or oblong shape, the link being free
to work or slide in the loop but being otherwise firmly confined therein. On the
opposite meeting rail or bar I secure a corresponding metallic plate carrying in
place of the staple or loop and the link a pin or pivot on which is mounted a flat
curved head or thumbpiece over which the link may be passed. The head is now
turned and the link secured, or a pin surrounded by a turnbutton or thumbpiece
may work in a socket in the plate, or other devices of a like nature may be
employed.
The plates carrying the link and moveable head or turnbutton respectively are
so fixed on the meeting rails (and in accordance with the length of the link) that
when the link is passed over the pin and secured by the turnbutton the sashes are
drawn together, draughts excluded and rattling prevented.
It will also be seen that it will be difficult for burglars or other persons to open
windows secured by these fastenings from the outside.
Although I have described my invention as applied to sash fasteners it may be
used for a variety of different purposes.

COMPLETE SPECIFICATION.
Improved Fastener for Doors, Windows, Boxes, and the like,
especially applicable as a Sash Fastener.
I, JOHN ABBOTT PICCAVER of 2 Newland Chambers Northampton in the
County of Northampton Architect and Surveyor 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 :-
The object of my invention is to provide a means for firmly economically and
simply securing the meeting rails or bars of window sashes in such a manner that
the securing device cannot be released from without by means of a knife or other
instrument being passed between the said meeting rails or bars.
My securing device may also be applied to doors boxes and the like.
Referring to the accompanying sheet. of drawings on which
Figure 1 is a sectional elevation and Figure 2 a plan showing my fastening
device applied to window sashes, and
Figure 3 is a view of my fastening device.
I will proceed to explain the nature of my invention and in using the fastening
for securing window sashes I prefer to form the meeting rails or bars with their

page_text: meeting faces diagonal instead of vertical as shown by A A' Figure 1 upon these
meeting bars or rails A A' I secure by screws or otherwise metal plates B B'.
On the plate B I form or fix a loop strap or staple C through which has been
passed an elongated loop or link also of metal such as D of sufficient strength to
withstand ordinary pressure.
On the opposite plate I mount a pivotted thumb piece or turn button such as E
which may be of any convenient shape but having one side of its pin F swelled out
or further from the centre than the opposite one the head is also curved to allow of
the link D being readily passed over it.
The head of the button is flush with the pin or pivot on one side the opposite
side projecting considerably beyond the pivot as G so as to confine the link D
when passed over it and the button turned.
When the plates are secured to the meeting rails it will be seen that when the
button head E is turned with its projection G inwards or towards the opposite
plate the loop or link D which is free to work within the staple C may be passed
over it and when the button is turned in the opposite direction the link or loop is
held firmly against the pivot pin F and prevented from rising by the projecting
portion of the head G the meeting bars being drawn closely together so tending to
exclude draughts, dust, noise, burglars and prevent shaking of sashes.
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. For securing the meeting bars or rails of window sashes or the like the use of
plates such as B B the one carrying a loose link running through a loop or staple
to pass over and be secured by a turnbutton such as E pivotted on the opposite
plate substantially as hereinbefore described with reference to the accompanying
sheet of drawings.
2. The means for securing the meeting rails or bars of window sashes substantially
as described and as illustrated by the accompanying sheet of drawings.
