I, WILLIAM WILKES Lock Manufacturer Mill Lane Works Bloxwich Walsall
County of Stafford do hereby declare the nature of any invention for AN IMPROVE-
MENT IN STRIKING PLATES OR STAPLES FOR RAILWAY CARRIAGE AND OTHER
CARRIAGE DOOR LOCKS to be as follows :-
This invention is intended to aid and render more perfect the action of Railway
Carriage and other carriage door locks, of the kind known as double action locks,
i.e. locks which have two motions, the first of which is automatic, and secures the
door shut when closed, by partial self locking.
The second action or full throwing of the lock bolt into the striking plate or
staple being done by hand force, applied to the lock handle.
In locks of the kind to which this invention applies, the bolts when not fully
thrown out are maintained or held in a position part way out and when the door
is being closed the bolt must be forced into the lock while passing the face of the
striking plate by contact with the plate, and when the door is fully closed the bolt
is automatically part locked and the door secured as closed.
The second action, or further complete locking being left to usual attendants or
passengers.
It is found that fixed or rigid striking plates often offer an inconvenient
resistance to the closeing of the doors when such locks are used.
Now I propose by my invention to ease, help and facilitate the working of
double action locks, by the provision and use of a Roller placed in the striking
plate at the point of first contact with the partially open bolt.
This roller will avoid much of the friction usually experienced.
:
I shall call my invention, an antifriction roller striking plate or staple, and shall
construct if as follows.
I prepare a plate of any suitable metal, either wrought or cast; This plate is to
be fastened on the door way jamb opposite the lock on the door when closed.
A recess is cut or cast in this plate into which the lock bolt enters in order to
hold or secure the door when closed.

page_text: When a door fited with a double action lock is being closed, the bolt being part
way out strikes against the staple or plate, the bolt being beveled at the part first
in contact.
On the outer edge of my striking plate I place a roller.
In closeing the door the projecting bolt first strikes this roller, and in passing by
the roller is pressed into the lock while so passing-Having passed the roller the
bolt is in a proper position to slip or glide over the face of the striking plate till
the door is fully closed, when the lock bolt is automaticealey shot or sprung outward,
and enters some distance into the recess of the striking plate or staple, and so
secures the door closed.
The object in view in the use of my roller-is to avoid the wear and risistance
of friction, found so injourious and inconvenient when lock bolts are struck against
rigid and fixed plates, and requireing consederable force when the bolt is to be
pressed inward by a passage over solid and fixed beviled surfaces which cannot
conveniently be oiled or lubricated without being liable to injure the garments of 1
passingers.
It will be found that much less force will be required in closeing a carriage door
when a roller plate is used, and much very unpleasant jarring and slaming of doors
will be avoided.
Having ascertained the use and nature of my invention, and the manner in
which it is to be performed-I declare that what I claim is the use and provision
of a roller in the lock striking plates or staples of Railway Carriage and other
Carriage door locks as herein before described.

I, WILLIAM WILKES, of Mill Lane Works Bloxwich in the County of Stafford
Railway Carriage Lock Manufacturer, do hereby declare the nature of my
invention for "AN IMPROVEMENT IN STRIKING-PLATES OR STAPLES FOR RAILWAY
CARRIAGE AND OTHER CARRIAGE DOOR LOCKS," and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
This invention is intended to be used in conjunction with my Patent Locks
dated November 13th 1884 and numbered 14942 as also for bang or slam locks of
every other description and consists in the use of a roller placed in the striking-
plates which are supplied with locks which are mortised into carriage doors, and
also staples which are supplied with locks which are fixed upon the outside of
carriage doors, for the purpose of assisting the easy striking of the bolts of such
locks into their respective striking-plates or staples-These striking-plates I slightly
bevil in front and behind the roller.

p—Fig. 5 is side view of Fig. 4.
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
The employment of a roller in striking-plates and staples, substantially as herein
described and illustrated by the drawings.
