IMPROVEMENTS IN AND RELATING TO KEEPERS OR STRIKING PLATES FOR THE LOCKS OR LATCHES OF RAILWAY-CARRIAGE OR OTHER DOORS
Year: 1885

page_text: I GORDON DONALDSON PETERS of Moorgate Works, Moorfields, in the County
of Middlesex, Manufacturer, do hereby declare the nature of my invention for
"IMPROVEMENTS IN AND RELATING TO KEEPERS OR STRIKING PLATES FOR THE
LOCKS OR LATCHES OF RAILWAY-CARRIAGE OR OTHER DOORS" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention relates to keepers or striking plates for the locks or latches of
railway-carriage or other doors.
The object of my said invention is to provide simple and efficient means whereby
the keeper or striking plate can be adjusted to compensate for the wearing away
of the part against which the latch or bolt bears when the door is fastened, thus
maintaining the proper position of the said part relatively to the latch or bolt and
preventing rattling of the door.
In the accompanying drawing.
Figure 1 is an elevation shewing my improved apparatus applied to a door post.
Figure 2 is a similar elevation shewing the said apparatus with part of the
same detached.
Figure 3 is a section on the line x x Figure 1.
a indicates the door-post and b a bed-plate fitted into the said post so as to be
flush with the outer surface thereof, as shewn in Figure 3, and secured by screws c.
This bed-plate b is provided with a recess d and with slots e, f, f; corresponding
grooves are formed in the door-post.
In the recess d is a plate g, which is of the same length as the said recess but
somewhat narrower, so as to be capable of moving laterally therein. The outer
surface is flush with the surface of the bed-plate band the inner surface has on it
lugs h, h, which extend through the slots ff into the corresponding grooves in the
door.
The plate g is formed with an aperture i into which the latch or bolt of the
door-lock or fastening enters. This aperture coincides substantially with the
aperture e in the bed-plate, except that the aperture e is somewhat wider than
the aperture i to afford free space for the latch or bolt whatever may be the position
of the plate a.

page_text: Screws inserted in the door-post pass through screw-threaded holes in the
lugs h. By turning these screws, the plate g can at any time be moved or adjusted
into the required position, so that the latch or bolt, when it enters the aperture ¿,
will be in close contact with the edge of the same, thereby preventing the rattling
of the door.
To ensure the retention of the plate g in the desired position after it has been
adjusted by the screws j, I form in the said plate elongated countersunk slots k
through which are passed screws l. These screws are inserted into the bed-plate,
and, when tightened, will prevent the accidental displacement of the plate g, but
will permit it to be readily readjusted when necessary.
In some instances I dispense with the bed-plate and fit the striking plate in a
recess formed in the door-post.
I do not confine myself to the use of the screws for adjusting and holding the
striking plate, as it is obvious that any suitable means may be employed for this
purpose.
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 above described improvements relating to keepers or striking plates for the
locks or latches of railway-carriage or other doors, whereby such keepers or striking
plates are rendered adjustable, as, and for the purpose, specified.
