Improvements in Door and Window Fittings.
I WILLIAM GRIFFITHS of 38 Singleton Terrace Swansea in the County of Glamor-
ganshire, Carpenter, do hereby declare the nature of my invention for IMPROVEMENTS
IN DOOR AND WINDOW FITTINGS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
:-
My invention of Improvements in door and window fittings consists of a metal
plate with a stud or pivot running through the centre pressed down by a flat spring.
The stud or pivot is fitted loosely in the top plate and is forced into the bottom plate
by means of the spring. The top plate carrying the spring is fastened to the top of
the door frame by means of a screw hole at each end. A plain strip of metal supported
by a screw at each end is fastened to the top of the door (directly opposite and under-
neath the plate in door frame) with a hole in the centre to receive the stud or pivot.
The hinge fastened to the floor, (underneath the bottom of the door) is a plain strip
of metal with a screw hole at each end, and a stud or pivot fastened firmly in the
centre. Another plate with a screw hole at each end and a hole in the centre (which
fits loosely on the stud or pivot) is fitted in the bottom of the door, opposite and over
the other plate with the said stud or pivot.
This invention can also be used as a door fastener or catch which acts as an automatic
catch. But by using it as a catch the stud or pivot does not require to be so long as
in the door hinge and is rounded off at the point. A small metal plate with a screw
hole at each end and a hole in the centre is fitted lengthways in the door-frame, and
the said plate must be bevelled off on the outer edge for the purpose of receiving and
forcing back the stud or pivot in plate fitted lengthways in door. When the door is
closed the spring forces the stud or pivot into the hole of plate fastened in door frame.
The stud or pivot is so rounded off that when the door is pushed the stud or pivot
will be forced back and thus allow the door to open.
This invention may also be used as a sash or window fastener, in a similar way as
the said door fastener or catch, only it requires the use of a brass pin running through
the frame, as the stud or pivot in sash frame is longer than the stud or pivot in door.

page_text: Fig. 1 represents the edge view of top plate fastened to door frame at the top of
door. A is the stud or pivot. B, is the flat spring for pressing down the said stud
or pivot. C, is the hole for the purpose of pushing a piece of wire (or anything
convenient) through to lift the spring and stud or pivot, when the door can be removed
and replaced.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is a plate of metal with a screw hole at each end and a hole in the centre
to receive the stud or pivot of Figs. 1 & 4.
Fig. 4 is a plate of metal with a screw hole at each end. B, is the stud or pivot
made fast or solid to the said plate. Fig. 5 represents a door and door frame, showing
catch or fastener and hinges in dotted lines. Fig. 6 is a window sash showing fastener
in position of flat view, in dotted lines. Fig. 7 is an enlargened portion of sash frame,
showing top view of centre cross piece of Fig. 6. It shows the catch or fastener in
dotted lines. E, is a push for forcing back the stud or pivot to allow the frame to
open. F and G are portions of cross pieces. H, is an edge view of Fig. 1 in position.
When the window is closed the catch or fastener is not in sight so cannot be opened
from the outside. Push E may be made to remain in the frame F, or may be made
to remove and to act as a key to unfasten the window. Fig. 8 is shewing a bracket
above stud or pivot for the purpose of keeping the said stud or pivot in a steadier
position for strong and heavy hinges and fasteners.
Having now particularly described 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
(1.) The stud or pivot fitted loosely in a piece of plate metal and a flat spring for
the purpose of forcing the said stud or pivot down.
(2.) To use this invention for door hinges door fasteners, sash fasteners and other
similar purposes.
