PROVISIONAL SPECIFICATION.
Improvements in Sash Fastening.
I, CHARLES THOMAS CRAWLEY, of 1884, Walworth Road, in the County of
Surrey, in the City of London, Coal Porter, do hereby declare the nature of this
invention to be as follows:
I construct a pice of brass, by preference, 3 in. long thick, with a round hole
through the center, with a slot at the back, B. for the pin to draw back into,
when unfastened, as shown, A, Fig. 1. This is called the front cuplin.
It as a
I construct of brass the back cuplin which is 3 in. long in. thick.
hole driled through the center the shape of a keyhole upside down, and it is
bevelled from the top of the hole downwards, as shown E, Fig. 2. I construct of
brass a back cap 3 in. long thick, hollowed out for the point of the pin to work
round, and to hide it from outside view, that I sowlder on to the back cuplin as
shown at K, Fig. 3.
I then take a pice of round iron turned up at one end as shown at, P. At
the other end there is a collar, when turned causes the cuplins to thighten
together and there is a joint when undone turns back to keep the pin in its place
as shown X, Fig. 4. And there is a brass key that can be taken off as shown M,
Fig. 5. And the improvement and advantage's, claimed for this my invention,
are these that the key can be taken off and cannot be opened without it.

COMPLETE SPECIFICATION.
Improvements in Sash Fastening.
I, CHARLES THOMAS CRAWLEY, of 91, Crampton Street, Walworth, S.E., London,
late of 1884, Walworth Road, London, S.E., Coal Porter, 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 consists of fastening for the sashes of windows the parts of which
fastening are constructed and combined, and act substantially; described and
illustrated in the accompanying drawing's.
One part of my invention consists of a pin. It has a tooth at one end, and
a collar at the other, between the collar and the tooth is a spring, this said pin
works in a hole with chambers.
The front section with hole, which has chambers; on front sash, and the other
part of the fastening on the other sash. This second part of the fastening has a
hole for the tooth of pin to pass in and out. When pin is in and turned round to
right or left it securely fastens the window.
The advantage of this invention is when fastened the window can only be
opened from the inside and then only with the key supplied as per Fig. 3,
although I claim for sash fastening, it is also applicable for doors and the like.
Fig. 1 of the accompanying drawings represent in plan my invention fastened,
with the top cut off.

tooth draws back into, so as to allow the two sections to pass each other.
Fig. 6 showing front section. H. H are the marks on the collar of pin and the
front of the fastening to denote where the tooth of pin is, when turned to corre-
spond the pin would fly outwards. I showing the position of the spring, G, G are
the holes for the key to fasten or unfasten by. K. K. are dummy holes.
Fig. 7 is the back section.
The chamber C runs off a bevel into chamber D for the purpose of drawing
the two sashes tightly together when the pin is turned round.
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
Fastening for the sashes of windows, doors and the like. It consists of a
pin Fig. 2 working in chambers A, B, C, D.
The collar of pin E has holes G, G for the key, and K, K are dummy holes.
The tooth J & spring 1.
The several parts of the fastening being constructed as hereinbefore described
and illustrated in Figures 1, 2, 3, 4, 5, 6, 7 of the accompanying drawings.
