WINDOW SASH FASTENINGS
Year: 1885

page_text: I JOHN SHARP of 5 Ethel street, Larcom street Walworth in the County of
Surrey Engineer, do hereby declare the nature of my invention for WINDOW SASH
FASTENINGS to be as follows:-
My invention relates to a safety, self-acting, locking, fastening for window sashes,
sky-lights, doors, and other purposes, consisting of an apparatus to be worked bý
means of a cord, chain, lever, or any simular appliance, to open and lower the top
and bottom sashes of a window. This simple operation pulls out a locking bolt
from a box fixed on the top sash. Then by closing or shutting the top sash of the
window the locking bolt is passed by the box and slides into the said box by means
of a spring thus locking the sashes by a self-acting process with perfect safety and
security. The apparatus consists of a frame for the locking bolt to, work or slide
in. The said frame is fitted with a tongue or rib to fit into a groove in the cover
or safety plate which is the bottom of the afore said locking bolt box which safety
plate pievents anyone from using a knife or a burglar using his implements to
force back the locking bolt which makes it burglar proof. The said bolt is kept in
its place by a spring I also include in my invention a small pulley in the end of
the locking bolt, to facilitate the working of the cord, and prevent its wearing And
I also include in my invention the complete arrangement of opening shutting and
safety self-acting locking of windows sashes doors sky-lights and for other purposes
with a hardened steel cover plate as described above, on the bottom of the bolt
box, where required to prevent the locking bolt being cut or sawn assunder.

page_text: I, JOHN SHARP 5 Ethel street Larcom street Walworth in the County of Surrey
Engineer do hereby declare the nature of my invention for WINDOW FRAME
SASHES, DOORS SKYLIGHTS AND OTHER PURPOSES 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 apparatus consisting of a metal frane A for a locking
bolt B to slide or work in fixed on the top of the bottom sash 1 of a window frame,
and a box C fixed on the bottom of the top sash 2 to receive the said locking bolt B.
The said locking bolt B slides into the said box C as the top sash 2 is being closed
by means of a spring D. The locking bolt B frame A and the locking bolt box C
are fitted with tongues or ribs E corresponding with grooves F in the said locking
bolt frame A and box C which the aforesaids fit into namely the tongues E into
the grooves F and prevents the sashes shaking. The bottom of the said locking bolt
box C is a safety or cover plate K as it hides the underside of the locking bolt B.
The said plate K may be made of hardened steel where required to prevent it being
cut or sawn assunder, it also prevents any one useing a knife or a burgular his
implements to force back the said lock in bolt B. Therefor it is burgular proof.
This apparatus may be fixed on any window frame sashes without interfering with
the present fastenings.
To fix the said apparatus I fix a small eye G in the top sash 3 and tie a cord to
the same and bring it downwards and put it through the end of the locking bolt B
against a pully H to facilitate the working and prevent this said cord wearing,
this said cord is then carried upwards and forms a loop for the opperator to take
hold of when useing, the said cord is then continued upwards over a pully I
fixed on the top of the bottom sash 2 and tied to the small eye J fixed on the
bottom of the top sash 2. Then by pulling the said cord tied to the eye G fixed
in the top of the top sash 3 the said locking bolt B is drawn out of the box C and
opens the top sash 3. Then by pulling the other end of the said cord the top and
bottom sashes 3, 1 can be closed and safely lock'd by simply pulling the said cord
with perfect ease and security.
I do not confine myself to a cord to pull out the locking bolt B, it may be done
by a cord chain, lever, or simular appliace.
Having now particularly discribed 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
First. The said safety or cover plate K tongued E and grooved F.
Secondly. The complete arrangement L of opening the top sash 3-2 and closeing
the top and bottom sashes 3-2 and 1 with self-acting locking of window frame
Bashes, doors, skylights and other purposes, with perfect safety and ease.
Dated this 13th day of March 1886.
