Improvements in
UCAS OF
other Doors and in the Manufacture thereof.
I JOSEPH WROE of number 269 Stockport Road Gorton in the County of Lancaster
Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN LOCKS OR
FASTENINGS FOR RAILWAY CARRIAGE AND OTHER DOORS AND IN THE MANUFACTURE
THEREOF to be as follows:-
I construct a square or oblong case or box of brass iron or other suitable material
of a convenient size in two parts-The one part forming the back and sides of a
square or oblong case or box for containing the working parts and in this case or box
I form two or more guides at right angle from fulerum of catch or bolt between these
I form a loose
two or more guides which are firmly fixed to back of case or box.
slipper to protect spring of India rubber or steel or other suitable material from the
wearing part of catch or bolt-The catch or bolt I form of convenient shape so as
to be partly selfacting and when turned a quarter of a revolution by an ordinary square
key or handle it forms a hook holt-For simplicity of understanding my claims I
give the following namely:-I place at back of bolt or catch suitable springs of
India rubber or steel working direct upon the fulcrum of bolt or catch -The other
part of case or box forming the lid or cover I dovetail in such a manner that when
the two parts are fitted together they may be fastened with or without screws so
that in the manufacture thereof there is combined simplicity with strength.

I, JOSEPH WROE of Number 269 Stockport Road Gorton in the County of
Lancashire Engineer, 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:—
1 construct a square or oblong case or box of brass, iron or other suitable material
of a convenient size in two parts, the one part forming the back and sides of a square
or oblong case or box for containing the working parts and in this case or box 1 form
two or more guides at right angles from fulerum of catch or bolt. Between these
two or more guides which are firmly fixed to the back of case or box, I form a loose
slipper to protect springs of india rubber, steel or other suitable material from the
wearing part of catch or bolt. The catch or holt I form of convenient shape so as to
be partly self acting and when turned a quarter of a revolution by an ordinary square
key or handle it forms a hook bolt. For simplicity of understanding my claims I
give the following viz-I place at back of holt or catch suitable springs of india
rubber or steel working direct upon the fulcrum of bolt or catch. The other part of
case or box forming the lid or cover I dovetail in such a manner that when the two
parts are fitted together they may be fastened with or without screws so that in the
manufacture thereof is combined simplicity with strength.
And in order that my Invention may be fully understood & readily carried into
effect, I hereunto append a sheet of drawings, to be hereinafter referred to, the several
parts being marked with letters for convenience of reference.
Figs. 1, 2 & 3 are vertical sections of various modifications of my Invention and
Fig. 4 is a front view of the modification shown in Fig. 3.
The
The case or box B as illustrated in the figures is of an oblong shape, but may be
square or any other convenient shape, and is made of brass iron or other suitable
material by casting, stamping, or in some other convenient manner. It is made in
two parts, one B forming the body and the other B¹ the front part of the case.
front part B may be formed with one side of the box B attached to it and it may be
dovetailed to the case Bas shown at in Fig. 1, but if desired the front plate B'
and side of the case B may be simply fastened to case by screws as shown in
Figs. 2, 3 & 4. The front part B' may be made separately and dovetailed to the box B
as shown at in Fig. 1 being attached by dovetails only, by screws only, or by a
combination of the two as desired. A slot is formed in the front of the case B'
through which the catch or bolt A works. The catch or bolt A is constructed with a
rounded nose or hook A and is actuated in the usual way by the introduction of a
handle or key in the square hole F formed in the catch. The slipper D is arranged to
be kept in contact with the back or tail A' of the catch A, by means of the springs CC
which are placed at the underside of the sipper D and between it & the bottom of the

page_text: case B being ordinarily slightly compressed so as to press the slipper D upwards.
The slipper D may be guided vertically by the front & back of the case or box B¹ B
as shown in Figs. 1 & 2, or in case of larger sized locks two vertical guides g g are
fixed in the case B, so as to act as guides for the slipper D as shown in Fig. 3. The
slipper D may be also formed of a T shape, as shown in Figs. 1 & 3, or with a hollow
cylindrical, oblong or square head & body as shown in Fig. 2. The springs CC may
be made of wire, made from steel, brass, or other material as shown in Figs. 1, 3 & 4
or may be of round, square, or oblong pieces of india-rubber as shown at in Fig. 2.
The catch or bolt A is ordinarily kept in the position as shown in the drawings, but
can be easily turned backward, so as to allow the door to which it is attached to open
readily. When the catch A is so turned back the springs CC are compressed the
pressure of the springs causing the catch A to again assume the position shown in
the drawings when it is released. The catch or bolt A is rounded at one side of the
nose A as shown in Fig. 4 so that when the door to which the lock is attached is
closed the catch A will move on its fulcrum into the case B and allow the door to
close after which the pressure of the springs CC acts upon the slipper D which
presses against the back or tail A' of the catch A in the manner herein described & so
causes the catch A to fall into the notch or hole formed to receive it in the frame of
the carriage. If it is desired to further fasten the door the catch A is moved a quarter
of a revolution so that the nose or hook A2 is downwards in which case the pressure
of the springs pushes the slipper D against the catch at a point immediately under
the fulerum thus keeping the catch firmly in position.
Having now particularly described and ascertained the nature of my Invention &
in what manner the same is to be performed, I declare that what I claim is
1st. In the construction of locks or fastenings the combination of a slipper, kept in
contact with the back or tail of a catch, by the action of a spring or springs and
retained in a vertical position by guides substantially as herein described & illustrated.
2nd. The use of a slipper, pressed against the back or tail of a catch by a spring or
springs for the purpose and in the manner as herein described & illustrated.
3rd. The manufacture of locks or fastenings in which a slipper, a spring or springs
& guides are combined with a catch or holt substantially as herein described &
illustrated.
