An Improved Window-sash Fastener.
I JOSEPH GOSTICK GOODWIN of 40 Friern Road East Dulwich in the County of
Surrey, Commercial Traveller do hereby declare the nature of this invention to be as
follows:-
A piece of metal cast or otherwise, somewhat in the form of a box with open ends;
so arranged as to allow a bolt (of peculiar shape) and screw to pass through side by
side;
is fixed to bottom sash. A similar piece is likewise fixed to top sash to receive
The
the bolt and screw: a suitable knob or handle being provided for their use.
Automatic
apparatus so made is reversible by turning upside down and let in.
provision is made for stopping and holding the bolt at its extremities. The screw
may be made to ride inside the bolt; the bolt being prepared for that purpose, and
by increasing its depth with that of the boxes: the whole being then worked by the
knob or handle of the screw alone; with the automatic stop remaining substantially
the same.
The reversible form with the other may be used with bolt alone if desired
the screw being used in either case for closing only.

page_text: I JOSEPH GOSTICK GOODWIN of 40 Friern Road East Dulwich in the County of
Surrey, Commercial Traveller, 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 nature of the several improvements will be understood from the following
description reference being made to the accompanying Drawing in which Fig. 1 is a
sectional plan view, of which the cases a and b form a part of the fastener, in its
reversible form of adaptation.
The fastener consists of the cases a and b, lightened out where possible, and so
constructed as to allow the bolt e of peculiar form to pass through the case a, or that
one which is fixed or attached to the bottom sash; its peculiarity being, that it is so
shaped at its end, or that part which enters the other or back case b, that upon its
entry the sashes are adjusted and placed in their proper position for fastening.
An automatic fastening is provided in the plate c, for securing the bolt e; grooves H
being cut at defined places in the top surface of the bolt e for the plate c to fall into ;
the principal groove being that one immediately at the end and adjoining the knob
or handle. The slot g in bolt e is for the purpose of preventing the possibility of
pulling the bolt e past its appointed position for the use of the automatic plate c, the
screw passing through case a and bolt e for that purpose mainly, but is used likewise
in conjunction with the other screws for fixing to the wood-work. The automatic
plate c is held sideways in the case a by being dovetailed in, while its weight is
supported or carried by the bolt e.
In conjunction with, and by the side of the bolt e, is a screw I passing through the
ease a and engages with the back case 6 for drawing together or closing the sashes.
The height or depth of this form of fastener is such as to admit of its being turned
upside down and let in flush, (or the thickness of flanges alone projecting above
wood-work as may be most desirable) but in doing so, it would be necessary to with-
draw the bolt e and the automatic plate c, reversing the position of the cases a and b
only. This would place the bolt e and screw D on the opposite hands of the operator.
Fig. 2 is an end elevation and Fig. 3 a side elevation.
Figs. 4, 5, 6 is another form of the same fastener, more suitable for fixing on
top of wood-work or meeting rails of sashes; Fig. 4 being a sectional plan, Fig. 5
an end elevation, and Fig. 6 a side elevation: K the front case and I, the back case.
In this form the screw M is carried by the bolt N and engaged with it; the bolt N
being propelled or actuated by the knob or handle of the screw M.
The bolt N is forked at the one end, to escape the block of metal containing or
forming the nut for the use of the screw M, and is likewise shaped at that end for
the purposes as before described in Figs. 1, 2, 3.
The bolt N is the full width of case K up to a certain distance when it shoulders or

page_text: sets back thus forming a stop with the aid of the screws P and P, and bringing the
notch or groove Q into the right position for the use of the automatic plate O.
The screws P and P are also used for fixing, in conjunction with those through the
flanges.
One other purpose is also served by the screws P and P; viz to guide the bolt e
through the automatic plate O should that become necessary.
The fasteners are made of brass or other suitable metal, cast or otherwise; with the
screws D and M of iron with brass knobs or handles, or they may otherwise be made
as may be most suitable for the purpose.
The application of Figs. 1, 2, 3 supposing the sashes to be already un-fastened, is to
raise the automatic plate c, and push the bolt e forward for fastening until it comes in
contact with screw, when the automatic plate e falls or drops into the groove H next
the knob or handle, and the bolt e becomes locked; then the screw D may be used for
drawing together or closing the sashes.
To unfasten. Lift the automatic plate and with the same hand withdraw the bolt e
as far as possible when it becomes dis-engaged with the back case band the automatic
plate falls into the second groove H and remains permanently unfastened till fastened
purposely; supposing the screw to have been already with-drawn. The screw D is at
the option of the user, but when the bolt e has been used, the position of the back
case & with regard to the use of the screw is rendered certain.
The application of Figs. 4, 5, 6 supposing the sashes to be un-fastened, is to raise
the automatic plate O and push the bolt N home by means of the screw-knob or
handle, when the automatic plate falls as before into the groove Q and the sashes
become locked; then by turning the screw M they are drawn together or closed.
To un-fasten, withdraw the screw M from the back case L only, lift the automatic
plate O and withdraw the bolt by means of the screw-knob or handle and the effect is
the same as described in Figs. 1, 2, 3.
The utility of the bolt e, plate e, an screw D in Figs. 1, 2, 3 and the corresponding
bolt, plate, and screw in Figs. 4, 5, 6 is the same.
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 :-
1st. In a fastener for window-sashes the combination and arrangement of the cases a
and 6 with the bolt e, and its automatic fastening plate c, and the screw D substantially
as described and for the purposes set forth and shewn in Figs. 1. 2 3. as suitable for
letting into the meeting rails of any window-sashes, or standing upon them and fixed.
2nd. The form of bolt e and the automatic fastening plate c of the screw sub-
stantially as described and for the purposes set forth and shewn in the drawing.
3rd. The combination of the cases a and b with the bolte and automatic plate e of
the screw with (or without the application of the screw D; thus narrowing the
cases).
4th. The combination and arrangement of cases K and L in Figs. 4, 56 with the
bolt N and screw M and the automatic fastening plate O of the screws P and P each
and all, as and for the purposes set forth and shewn in the Drawings.
5th. The combination of bolt N and screw M of the cases K and L, with the
automatic fastening plate O and the screws P and P substantially as described and
shewn in the drawing.
