Complete Specification Left. 13th Feb., 1891-Accepted, 14th Mar.. 1891
PROVISIONAL SPECIFICATION.
An Improved Self-acting Shutter Holder.
A communication to me from abroad by JAKOB HILB, Merchant, of Esslingen, in
the Empire of Germany.
J, EDMUND EDWARDS, of the firm of Edwards & Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a self-acting fastening for holding hinged shutters
securely in their places.
Supposing the shutter turns in the usual way upon hinges at one of its edges, the
hinges being fixed to a window frame or other support, a stud or pin is also fixed in
a suitable position in such frame or support, upon which stud a short lever turns
freely, its upper end being rounded and bevelled so that one of the edges of the
shutter presses against it and moves it out of the way until the shutter has passed
its point when it returns to a vertical position by the weight of its lower end, and
so prevents the shutter from being moved back until the lever has been first moved
out of the way by hand.
The stud may have a screw thread formed upon it, upon which fits freely a
corresponding stud on the lever, so that the position of the latter may be adjusted
by screwing it in or out upon the stud.
The improved fastener is very simple, cheap, and durable, is automatic in its
action, and holds the shutter perfectly securely.

COMPLETE SPECIFICATION.
An Improved Self-acting Shutter Holder.
A communication to me by JAкоB HILB, Merchant, of Esslingen, in the Empire of
Germany.
I, EDMUND EDWARDS, of the firm of Edwards & Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawing, that is to say :-
This invention has for its object a self acting fastening for holding hinged shutters
securely in their places.
The accompanying drawing is in illustration of the invention.
Figure 1 is a front view of a shutter, closed, and
Figure 2 the same partly closed.
Fi
Figure 3 is a plan of Figure 2, and
Figure 4 represents the holder separately.
Supposing that the shutter A. turns in the usual way upon hinges C at one of its
edges, the hinges being fixed to a window frame or other support B a stud or pin H
s also fixed in a suitable position in such frame or support B, upon which stud a
hort lever V turns freely its upper end $ being rounded and bevelled so that one
of the edges K of the shutter presses against it and moves it out of the way until
he shutter has passed its point, when it returns to a vertical position by the weight

lever has been first moved out of the way by hand.
The stud H may have a screw thread formed upon it, upon which fits freely a
corresponding thread upon the lever at X, so that the position of the latter may be
adjusted by screwing it in or out upon the stud.
The improved fastener is very simple, cheap, and durable is automatic in its action,
and holds the shutter perfectly securely.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A shutter holder V, which when the shutter A is closing turns upon a stud or
pin H fixed in the frame B, and when the shutter is closed is turned up by its own
weight, and so automatically holds the shutter and prevents it from opening
substantially as described and shewn in the drawing.
