An Improved Lock Casing and Mode of Fixing same on Doors and the like.

An Improved Lock Casing and Mode of Fixing same on Doors
and the like.
I, RICHARD FREDERICK FITCH, of Gainsborough, Gippsland, in the Colony of
Victoria, Saw Mill Proprietor, do hereby declare the nature of this. invention
to be as follows; :-
This invention relates to an improved lock casing-and mode of fixing same
on doors and the like and which has been designed to provide a more convenient
means for securing the locks in position and in such a manner that they pro-
ject very slightly above the surface of door, also the handle can be permanently
secured in position. Furthermore the locks cannot be removed without the door
being open and the bolt or catch of lock enters a cavity provided in the door jamb
and hence does away with the necessity for having projecting catch boxes.
My improved lock casing or box has side or check-plates which are wider than
the actual lock box, also they project over the back end of said box and hence a
channel is formed around both the top and bottom edges and back of the lock
box. The front edge of lock casing or box is made with a bar which projects
above and below the width of the side cheeks. These lock casings are made of
various sizes in order that the width of channel will suit the thickness of door
upon which it is to be placed. To receive the lock the door has a rectangular or
other shaped piece cut clean out of it to fit the box proper of the lock and at its
edge it is rebated to receive the front edge plate which projects above and below
the side plates. Thus when the casing is in position the cheeks or side plates
of the lock casing project over the outer and inner faces of door and so hold the
lock firmly in position. Further screws are passed through the inside cheek
plate, through the woodwork of door and into the front cheek plate, and also the
front edge plate is held down by screws.
It will be obvious that said side plates which lie upon the face of door can be
made of any size and width and be suitably embellished to any design if so desired:
Further I do not limit myself to the mode of making the lock box or casing
as such can be done as ordinarily although in all cases when made in accordance
with my invention the casings must have the channel at the two edges and back
between the side plates or cheeks to receive the door.

page_text: in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to an improved lock casing and mode of fixing same
on doors and the like and which has been designed to provide a more convenient
means for securing the locks in position and in such a manner that the casing pro-
jects very slightly above the surface of door, also the handle can be permanently
secured in position. Furthermore the locks cannot be removed without the door
being open and as the bolt or catch of lock enters a cavity provided in the door
jamb there are no projecting catch boxes.
My invention will now be described aided by a reference to the accompanying
drawings in which,
Fig. 1 is a perspective view of a lock casing as fitted on a door.
Fig. 2 a perspective view of a lock casing oy itself and Fig. 3 shews the part
of door as cut to receive the lock.
Fig. 4 is a section and Fig. 5 a back view of the lock casing, the former shewing
the cheeks beaded and the latter shewing them flat.
My improved lock casing or box A has side or check plates a which are wider
than the actual lock box a, also the checks project over the back end of said box
and hence a channel is formed around both the top and bottom edges and back
of the lock box. Said cheek plates a may either be flat or be beaded or otherwise
embellished. The front edge of lock casing or box is made with a plate or
flange which projects above and below the width of the side cheeks. These
lock casings are made of various sizes in order that the width of channel between
the side cheeks a will suit the thickness of door B upon which the lock is to be
placed. To receive the lock the door has a rectangular or other shaped piece
cut clean out of it to form a space B in which to fit the box proper of the lock
and the edge of door is rebated at ₺ to receive the front edge plate a² which pro-
jects above and below the side plates. Thus when the lock is in position the checks
or side plates of the lock casing project over the outer and inner faces of door
and so hold the lock firmly in position. Further screws C are passed through the
inside cheek plate, through the woodwork of door and into the front cheek plate,
and also the front edge plate is held down by screws C¹.
As the handle bar in this form of lock casing does not pass through the wood
work of the door it can be permanently secured to the handles at each side of the
casing.
It will be obvious that said side cheeks or plates a which lie upon the face
of door can be made of any size and width and be suitably embellished to any
design if so desired, such as is indicated by dotted lines in Fig. 1.
Further I do not limit myself to the mode of making the lock box or casing as
such can be done as ordinarily although in all cases when made in accordance
with my invention the casings must have the channel at the two edges and back
between the side plates or cheeks to receive the door.
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:-
1. My improved lock casing having projecting side cheeks as a and front plates
as a, substantially as described and shewn.
2. A lock casing having a channel formed around its top, bottom and back to
take the material of the door it is to be secured upon substantially as described
and shewn.
3. A lock casing having a channel formed around its top, bottom and back and
having its handles permanently secured to the handle bar of lock substantially
as described.
4. A door having an open ended slot or gap as B¹ formed in it to receive a

and back, substantially as described and shewn.
5. My improved lock casing and mode of fixing same on doors and the like
substantially as described and shown.
