Improvements in Locks and Fastenings for Doors, Cupboards, and,
for other similar purposes.
We SAMUEL HILL of 57 Hockley Hill Birmingham in the County of Warwick
Cabinet Bar Fitter, and ROWLAND HODGES 12 Frederick Street Birmingham,
aforesaid, Manufacturer and Brass Founder, do hereby declare the nature of this:
invention to be as follows:-
Our invention relates to the manner in which we construct and arrange locks and
fastenings for doors, cupboards, drawers, and other similar purposes whereby we are
able to turn the key handle or operating knob or button in either a right or left
hand direction when opening or closing the door or when locking or releasing the
fastenings or catch.
In carrying our invention into effect, we construct a fastening for receiving a
handle and square spindle for attachment to a door, in the following manner :-We
form a front plate or cover plate with suitable screw holes for attaching it to the door,
and having a central circular hole to receive the projecting boss of the bolt or latch
we also pierce two or more holes within this plate for receiving projecting pins,
ends, or tongues from the back plate or cover, so that the front and back plates may
be riveted by these projections and securely connected one to the other.
The back plate we form with a bent flange on each side for the purpose of making
it embrace the locking bolt or latch when it is in position between the two plates;
and upon the flanges or sides of this back plate we form the projecting tongues or
pins to serve as rivets for securing the plates together. Within the centre of the
back plate we form a circular hole to correspond with the hole in the front plate, and
for the same purpose of receiving the projecting boss upon the lock bolt or latch of
the fastening. We also cast or pierce two holes within the back plate for receiving the
projecting ends of a circular metal spring, which we place and carry between the
two plates.
The locking pin, latch, or bolt, we carry between the plates, and form it out of flat
metal having a circular boss with a square or other hole passing through it, for
receiving the handle spindle, opener, or key. The boss of this lock or latch plate we
cause to project on each side and to enter the central holes formed within the front
and back plates of the case; we cut or form this latch plate or bolt, with two recesses
near to the boss, one upon each side of the flat surface, and these recesses we cause to
fit over and to receive the ends of the spring, which is. held in position within the case,
by the projections upon the ends as before described. Thus, when the lock or fasten-
ing is made up, it is in the form of a case containing a latch or holt which projects
beyond the edge of the case, and which latch or bolt is in part encircled by a flat bent
metal spring, the ends of which press one upon each side of the bolt and at the same
time engage with the back or cover plate of the case. The holes receiving the ends
of the spring are such that one end of the spring can be caused to move in one-
direction while the other can be moved in the opposite direction only when the latch
is operated upon by the handle.
Thus, should the latch be turned in one direction, one end of the spring will be
compressed and will cause it to return to its central or locked or fastened position ;
while, should it be turned in the reverse direction, the other end of the spring will
similarly cause it to return to its central position. So that in whichever direction the
handle is turned the lock can be released, and it will also again automatically return
to its locking or fastening position.
We prefer to employ a striking plate or catch plate for use with our improved
fastening, having one edge tapered or rounded off to guide the locking bolt or latch
from its closed of central nocition to its onen nasition and then to be caused to spring

page_text: behind this catch plate and retain the locking bolt or catch in its locked position. That
is to say, when the door having our improved fastening attached to it comes into
contact with the catch plate attached to the frame, the lock bolt is automatically
guided back to enable it to pass the catch plate, when it is again carried round
to its central locking position which thereby secures, or fastens the door. To
open the door the handle may be turned in either direction at will, as before
explained.
We do not limit the application of our improved fittings and fastenings to any
particular kind of door or frame, but adopt the same system of construction when
making locks and fastenings for railway and other carriage doors and also for securing
drawers and other similar purposes.

Improvements in Locks and Fastenings for Doors, Cupboards, and
for other similar purposes.
We; SAMUEL HILL of 260 New John Street West, Birmingham, in the County
of Warwick, Cabinet Bar Fitter and ROWLAND HODGES, 12 Frederick Street,
Birmingham, in the County of Warwick Manufacturer and Brass Founder, 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:
Our invention relates to the manner in which we construct and arrange locks and
fastenings for doors, cupboards drawers and for other similar purposes whereby we are
able to turn the key handle, or operating knob or button in either a right or left hand
direction when opening or closing the door or when locking or releasing the fastenings
or catch.
In carrying our invention into effect we construct a fastening for receiving a handle
and square spindle for attachment to a door in the following manner :-\
We form a
front plate or cover plate with suitable screwholes for attaching it to the door and
having a central circular hole to receive the projecting boss of the bolt or latch; we
also pierce two or more holes within this plate for receiving projecting pins, ends or
tongues from the back plate or cover, so that the front and back plates may be rivetted
by these projections and securely connected one to the other.
The back plate we form with a bent flange on each side for the purpose of making.
it embrace the locking bolt or latch when it is in position between the two plates; and
upon the flanges or sides of this back plate we form the projecting tongues or pins to
serve as rivets for securing the plates together. Within the centre of the back plate
we form a circular hole to correspond with the hole in the front plate; and for the
same purpose of receiving the projecting boss upon the lock bolt or latch of the
fastenings. We also cut or pierce two holes within the back plate for receiving
the projecting ends of a circular metal spring which we place and carry between the
two plates.
The locking pin, latch or bolt we carry between the plates, and we form it out of
flat metal having a circular boss with a square or other hole passing through it for
receiving the handle spindle opener or key. The boss of this lock or latch plate we
cause to project on each side, and to enter the central hole formed within the front
and back plates of the case; we cut or form this latch plate or bolt with two recesses
near to the boss one upon each side of the flat surface, and these recesses we cause to
fit over and to receive the ends of the spring which is held in position within the case
by the projection upon the ends as before described. Thus when the lock or fastening
is made up it is in the form of a case, containing a latch or bolt which projects
beyond the edge of the case, and which latch or bolt is in part encircled by a flat bent
metal spring the ends of which press one upon each side of the bolt and at the same

page_text: time engage with the back or cover plate of the case. The holes receiving the ends of
the springs are such that one end of the spring can be caused to move in one direction
while the other can be moved in the opposite direction only when the latch is operated
upon by the handle.
Thus, should the catch be turned in one direction, one end of the spring will be
compressed and will cause it to return to its central or locked or fastening position―
while should it be turned in the reverse direction the other end of the spring will
similarly cause it to return to its central position. So that in whichever direction the
handle is turned the lock can be released, and it will also again automatically return
to its locking or fastening position.
We prefer to employ a striking plate or catch plate for uso with our improved
fastening, having one edge tapered or rounded off to guide the locking bolt or latch
from its closed or central position to its open position and then to be caused to spring
behind this catch plate and retain the locking bolt or catch in its locked position-that
is to say when the door having our improved fastoning attached to it comes into
contact with the catch plate attached to the frame, the lock bolt is automatically
guided back to enable it to pass the catch plate, when it is again carried round to its
central locking position which thereby secures or fastens the door. To open the door
the handle may be turned in either direction at will as before explained.
We do not limit the application of our improved fittings and fastenings to any
particular kind of door or frame, but adopt the same system of construction when
making locks and fastenings for railway and other carriage doors; and also for
securing drawers and for other similar purposes.
-
In order that our invention and the manner of performing the same may be readily
understood we append hereunto one sheet of explanatory drawings to be hereinafter
referred to.
Fig. 1 is a front elevation of our improved locking catch with the handle or key
omitted.
Fig. 2 is an elevation of the same with the front or cover plate E removed; in
which A is the locking bolt or catch having a central projecting boss A' standing out
on each side and which fits into suitable holes formed in both the top and bottom
plates D, and E. The back plate D we form with flanges on each side and round the
bottom edge, while the upper edge we leave free to permit of the movement of the latch
or bolt A; upon the side flanges we sometimes form projecting tongues D³ D* to serve
as rivets or pins for connecting the two plates D and E together; although we some-
times employ screws when we wish to be able to take the plates readily apart for
examination of the fittings and for similar purposes. Around the boss A' we place the
circular spring having horns or projecting ends CC which engage with the back
plate D, by entering the holes D' D2 formed as circular grooves for the same. The
ends of the spring plate press against the recessed or cut under portions of the bolt A,
the one on each side thereof, so that in whichever direction the handle or key fitting
the square hole B is turned the spring C tends to cause its return to a central or
mid position.
Fig. 3 is a side elevation of our complete locking catch having a handle F and a
handle plate F¹ shown in position, the spindle E' being pinned or secured in any
ordinary manner to the handle.
Fig. 4 is a side elevation of the back plate D.
Fig. 5 is a side elevation of the lock or catch bolt.
Figures 6, 7 and 8 are detail views of the spring plate C.
Figures 9, 10, 11, 12 and 13 are detail views of the striking or catch plates we
employ by preference with our improved lock, in which H is the back portion for
attachment to the frame of the cupboard, cabinet, or carriage to which the lock is to
be fitted; H' is the curved guiding surface which directs the catch A to the recessed
back surface stop H2; when the lock is fitted for one movement; and when fitted for
moving in another plane the catch plate G is employed having its guiding or striking
surface G directing the lock bolt or catch A to the recessed portion or stop G².
Fig. 14 is a general perspective view of our catch.

page_text: We modify the catch plates and the particular form or shape of our improved locks
or catches to suit railway or other carriage doors, and to suit any peculiar form of
cabinet or cupboard door without departing from the essential features of. our
invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
clain is-
1. The construction of locking catches having a bolt or catch such as A, encircled
by a spring plate such as C, for application to cabinet doors, cupboard doors, and to
railway carriage and other doors substantially as hereinbefore described and in the
manner set forth in the accompanying drawings.
2. The construction of locks and locking catches having a plate such as D cut
away to receive the ends of a spring plate such as CC2 for permitting the move-
ment of the spring C in either direction, substantially in the manner herein before
described and as set forth in the accompanying drawings.
3. The combination and arrangement of a locking catch for the purposes
hereinbefore described, substantially as herein described and illustrated in the
accompanying drawings.
