COMPLETE SPECIFICATION.
A New or Improved Automatic Sash Fastener.
I, ALBERT GEORGE EWENS, of West Horsley, in the County of Surrey,
Engineer, 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 the
following statement :-
This invention relates to a new or improved automatic sash fastener and has for
its object to provide a simple and effectual means of securely and automatically
fastening windows and the like.
And in order that my invention may be the more readily understood I have
shewn the same upon the accompanying sheet of illustrative drawings, wherein ;-
Fig. 1 is a plan of the bolt-box.
Fig. 2 is an end view of same.
Fig. 3 is an end view of the catch for bolt.
Fig. 4 is a plan of the catch for bolt.
Fig. 5 is a sectional elevation shewing bolt and catch complete.
Fig. 6 is an end elevation of same.
Fig. 7 is a plan of another form of bolt box.
Fig. 10 is an end view thereof.
Fig. 9 is an end view of catch for bolt.
Fig. 8. is a plan of catch for bolt.
Fig. 11 is a sectional elevation shewing bolt and catch complete as shown in
Figs. 7. 8. 9 & 10.
Fig. 12 is an end elevation of same.
My invention consists of a cylinder a of brass, iron, or other suitable material
provided with lugs or wings 6 for securing to the sash, and a hole in the bottom c
of suitable form to carry the end of the bolt which in this case I shew square but
I do not restrict myself to any particular form.
On the bolt immediately behind this square portion is an enlarged circular
plate d against which the spiral spring e presses.
A cap of the cylinder is screwed or otherwise fastened to the cylinder and
brings the necessary tension on the spring when the head g is screwed on to the
bolt.
The bolt and box is now ready for mounting on the sash which can be done in
the one case as shewn in Fig. 5 by drilling the necessary holes for the bolt box
and attaching screws in the, sash.
In the other as shewn in Fig. 7 the attaching screws alone are required.
The catch can be made of brass, iron or other suitable material of the form
shewn and is correspondingly, secured to the other frame. The guide / on the
front of the catch presses the point of the spring bolt which is made of an inclined
plane, back, on the closing of the sashes until it drops in the hole in the catch
when the window is securely held..
To release the window the head of the bolt is taken hold of and drawn back
until the point k is clear of the catch when the sashes may be separated.
Having now particularly described and ascertained the nature of my said inven-
tion, and what manner the same is to be performed, 1 declare that what I
claim is
1. The new or improved automatic fastener for window sashes, and the like,
consisting of a bolt actuated by a spring in combination with a recess provided

page_text: with a guide for engaging and holding the said bolts ostantially as described and
illustrated by the accompanying drawings.
2. The improved fastener for window sashes, shutte s, and the like, substantially
as described and illustrated by the accompanying drawings.
