PROVISIONAL SPECIFICATION.
An Improved Sash Fastener for Windows.
1 WILLIAM HENRY PETLEY, of 2 Wharf Terrace, Medina Road, Cowes,
Isle of Wight, Ship Carpenter, do hereby declare the nature of this invention to:
be as follows:-
:
My invention relates to sash fasteners for windows.
The main object of my said invention is to provide a simple cheap and durable
fastener for window sashes that will bring them close together prevent vibration of
the frames and render it very difficult if not impossible to displace the fastener by
foul means for the purpose of opening the sashes from the outside.
In making a sash fastener according to my invention I provide and fix plates upon
the inside and outside at the front and back of the meeting bar of the lower sash and.
upon the inside of the meeting bar of upper sash another plate these plates are in
position opposite to each other, in or about the centre of the first. named. plate I
provide a circular hole and a hole is bored through the meeting bar of the lower
sash. In the plates fixed at outer side of the meeting bar of the lower sash and
on the inside of the meeting bar of upper sash I provide two threaded holes, all
the holes are in a line. I further provide a pin or bolt with a hardened steel
shank, threaded at its point, and a hinged finger plate is provided upon the head
of bolt.
To bring the meeting bars of sash frames together when the window is shut, and
to secure them, the bolt is passed from the inside of window through the plate fixed
on the inner sash bar, and through the latter (the sash bar) and then turned through
the threaded hole in plate fixed on the outer side of meeting bar of lower sash and
into the threaded hole in plate fixed upon the inside of meeting bar, of upper sash-
and the bolt tightened up by means of the hinged finger plate provided on, and
forming the head of bolt.
'
The outer plate on meeting bar of lower sash and the plate on inner side of
meeting bar of outer sash are both let into the sash bar flush with same.
The plate on inside of lower sash bar may be let in flush or not as desired.
Upon the front of the last named plate I provide on one, or both sides of the
bolt, a pin or projection and in the finger plate a hole corresponding in shape and
size to the said pins when the bolt is screwed home, the finger plate can be turned.
down over the pin, thereby locking the bolt and preventing its being turned from
the outside and the head of bolt that is the finger plate-will thus project, but
little from the sash bar.
To unfasten the sashes it is only necessary to unscrew the bolt sufficiently to
bring the point clear of the threaded hole in the plate fixed on the inner side of the
meeting bar of the upper sash.
An advantage following upon the use of my fastener is, that it does not harbour
dust and dirt upon the top of the meeting bars as do fasteners that are fitted in that
position.
More than one fastener may be fitted to the meeting bars of sash frame if found
convenient.

An Improved Sash Fastener for Windows.
I, WILLIAM HENRY PETLEY, of 2 Wharf Terrace, Medina Road, Cowes,
Isle of Wight, Ship Carpenter, 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:―
My invention relates to sash fasteners for windows.
The main object of my said invention is to provide a simple cheap, and durable
fastener for window sashes that will bring them close together, prevent vibration of
the frames, and render it very difficult if not impossible to displace the fastener by
foul means, for the purpose of opening the sashes from the outside.
In the accompanying drawings,
Fig. 1 is an elevation partly in section taken on the line a, a, of a sash fastener
made according to one form or modification of my invention,
Fig. 2 a plan and,
Fig. 3 a front elevation.
Fig. 4 an elevation, partly in section illustrating a modification of my invention
Fig. 5 a plan and
Fig. 6 a front elevation of same.
b, is a plate secured upon the front of the inside meeting rail of the lower sash;
c, a plate secured on the outside of same, d, a plate secured upon the inside of the
meeting rail of the upper sash; in the plate b, I provide a plain circular hole 6',
and a hole. is bored through the meeting rail of the lower sash. In the plates c,
and d, I form screw threaded holes; all the plates are fitted on sash rails so that
the holes in same are in a line with the hole bored through the lower sash rail. I
further provide a bolt e, with a hardened steel shank, screw threaded at its point,
and a hinged finger plate, is fitted upon the other end or head of this bolt.
To bring the meeting rails of sash frames together when the window is shut, and
to secure them in this position, the bolt e, is passed from the inside of window
through the hole b', in the plate b, and through the hole in the lower sash meeting
rail, and then turned through the screw threaded holes in the plates c, and d, and
the bolt tightened up upon the plate b, by means of the finger plate f.
Upon the front of the plate b, I provide on one, or both sides of the bolt e, a
projection, or projections g, g, and in the finger plate f, a hole is made in shape and
size corresponding to the said projections, when the bolt is screwed home the finger
plate can be turned over one of the projections g, thereby locking the bolt and
preventing any possibility of its being turned from the outside of window, in this
position of the finger plate it is evident that it will project but little from the
sash rail. To unfasten the sashes it is only necessary to unscrew the bolt
sufficiently to bring the point of same clear of the threaded hole in the plate d.
According to another form or modification of my invention, I may (referring to
Figs. 4, 5 and 6) sometimes dispense with the plate c, and arrange for locking the
finger plate, in the folded position by means of a small button h, turning on, or
with a pin passing through the projection g', when the finger plate is locked the
button h, will be in position as shewn at Figs. 4, 5, and 6, and when it is desired to
release, that is unlock the finger plate, the button is turned into position at right
angles to that shewn, the length and width of the button will then correspond with
that of the projection g' and the finger plate is free to be opened out upon its hinge
clear of the projection 9!, and button h, and the bolt el, can then be unscrewed at
will, and the window consequently unfastened.
I have shewn at Fige. 4, 5, and 6, only one projection g' to
but two such projections may be fitted if preferred, one on
and I have not provided a plate on inside of inner meeting
take the finger plate,
each side of the bolt,
rail corresponding to

page_text: the plate c, (see Figs. 1, 2, and 3) but such plate may or may not be fitted as found
most convenient.
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 :-
The improved sash fastener consisting of the parts constructed, arranged and
combined, substantially as described with reference to the accompanying drawings,
and operated as, and for the purpose specified.
