Improvements in and relating to Outside Carriage Door Locks
and Striking Plates."
I, HENRY DEFRIES of 147 Houndsditch, in the City and County, of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
-
My invention relates to improvements in outside carriage door locks and striking
plates or staples by the use of which the lock is protected from injury arising from
the presence therein, of dust, rain, snow or the like, and the invention is particu-
larly applicable to railway carriage door locks.
I form the striking plate or staple in a box shape having a length corresponding
to that of the front or open face of the lock. The front end of this box is closed.
and so shaped as to divert the stream of dust, rain or snow from the open face of
the lock.
In applying my invention to an ordinary. outside lock I. may form the inner edge
or face of the staple so as to correspond with the bolt of the lock, and in the case
of a double action lock to give to this face the necessary angle or other forination
requisite for operating the bolt.
.
I form at the underside of the lock casing one or more suitable slots or holes so
s to allow any dust etc. which may have entered the lock, to drop out,

plates or staples by the use of which the lock is protected from injury arising from
the presence therein, of dust, rain, snow or the like, and the invention is particu-
larly applicable to railway carriage door locks.
I form the striking plate or staple in a box-shape having a length corresponding
to that of the front or open face of the lock. The front end of this box. A is closed

rain or snow from the open face of the lock, as indicated by arrows.
My invention will be more clearly understood by reference to the accompanying
drawings, on which-Figure 1 is an elevation of an outside carriage door lock and
staple constructed according to my invention; Figure 2 being a plan of the same
seen from below.
A is the Staple or striking plate. B is the lock. C is the bolt, shewn in dotted
lines in two positions. D, the front face of lock; E, inner edge of staple; F,
slots or holes in bottom of lock, shewn in dotted lines."
In applying my invention to an ordinary outside lock as shewn on the drawing
I may form the inner edge or face E of the staple A so as to correspond with the
front face of the lock B, and in the case of a double-action lock I may give to this
face E the necessary angle or other formation at e requisite for operating the bolt,
as shewn.
I form at the underside of the lock casing, one or more suitable slots or holes, F,
shewn in dotted lines on figure 2, for the purpose of allowing any dust etc.
which may have entered the lock, to drop out.
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 :-
1. In outside carriage door locks, forming the striking plate or staple A of a
box shape corresponding in length to the open face I) of the lock, and shaping the
closed end of this box so as to divert the stream of dust etc. from the face of the
lock, for the purposes and as described.
2. In outside carriage door locks, the combination with a striking plate or staple A
as caimed in the preceding claim, of holes or slots F formed in the underside
of the lock casing, substantially as and for the purposes described.
3. Outside carriage door locks and striking plates, constructed combined and
arranged, substantially as described and illustrated on accompanying sheet of
drawings.
