Improvements in Sash Fasteners.
HENRY JOHN ANSTIE of 31 Market Place Devizes Wilts Gentleman 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 an improved sash fastener, and has for its object to
provide a suitable fastener which shall be burglar proof, and shall also hold the
sashes tightly together and prevent rattling.
In carrying out my invention I use two hollow cylinders of equal diameter, attached
by means of screws and plates to the middle rails of the window. The cylinder on
the lower bar of the upper sash is closed at its outer end, and has a slot at its upper
part, part of which extends from the front longitudinally and the other part at an
angle. A slot is also provided in the front cylinder, which, when the sashes are
closed, is continuous with the slot abovementioned. Inside this second cylinder is
situated a metal bolt capable of sliding therein, but secured by a plate at one end
and a pin sliding in the slots abovementioned.
When the window is to be fastened, the bolt is pushed in, extending into the first
cylinder as far as the pin and slot will allow, and then turned by means of a thumb
piece at the end, so that the pin passes into the second part of the slot, as far as a
small recess which retains it, the end of the bolt abutting against a spring or india-
rubber buffer which serves to prevent rattling. The second part of the slot above-
mentioned extends slightly forward so that when the bolt is turned, the sashes are
drawn together more closely.
Referring to the accompanying sheet of drawings
Fig. 1 is a vertical section, and Fig. 2 a plan of my improved fastener and Fig. 3
a section of a slightly modified form of fastener.
1 and 2 are the cylinders fixed by their plates to the rails 3 and 4, and forming
when the sashes are closed a continuous cylinder closed at one end. Inside the
cylinder 1 is situated the bolt 5 capable of sliding backwards & forwards, and of
entering into the cylinder 2 being held in the cylinder 1 by the end plate 6 and the
pin 7 sliding in the slot 8. The cylinder 2 has au india-rubber ring 9, or as shown
in Fig. 3, a helical spring 9, which, when the bolt is pushed into the cylinder, and
the pin 7 enters the angular slot 10, serves to press the pin tightly against the side
of the small recess 10" and prevent rattling.
When the spring 9" is used, the bolt has only to be turned back by the thumb
piece 11 to the corner of the angular slot to release the fastening, the spring pushing
the bolt out.
Having now particularly described & 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:
In a sash fastener, the combination of cylinders 1 and 2 fixed on the central rails
of the window, having slots 8 and 10, and the bolt with pin 7 sliding in the slots 8
and 10 and engaging therein substantially as described and shown and for the
purposes specified.
