PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Railway Carriage and other Doors.
JOSEPH KAYE 93 High Holborn London W.C. Lock Manufacturer do hereby
declare the nature of this invention to be as follows:-
The principle object of this invention is to prevent people falling out of railway
& other carriages & to prevent doors being broken, which are fitted with my
patent wedge locks, or other locks & to have the same or better effect than the
safety catch, which is in my carriage lock Patent No. 8073--1884 which fastens
the door by casy closing, some distance from being closed.
I accomplish my object, by fitting to the door pillar, a catch, which is held in a
sufficient projecting position by a spring, so that by the short projecting part of the
wedge from the edge of the door coming into contact with the catch, by the door
being closed, the catch recedes, until the wedge passes it, then the catch holds the
door, by the end of the wedge, until the wedge is drawn into the door, when the
door is fully released.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Railway Carriage and other Doors.
I, JOSEPH KAYE, of 93, High Holborn, London, in the County of Middlesex,
Lock Manufacturer, 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 :-
The principle object of this invention is to prevent people falling out of railway
and other carriages, and for the prevention of doors being broken, which are fitted
with my patent wedge locks No. 10530 of 1888 or other locks, and to have a
similar or better effect than the safety catch which is in my carriage lock Patent
No. 8073 of 1884, which fastens the door by easy closing some distance before the
door is finally closed.
I accomplish my object by fitting to the door pillar, a catch, which is held in a
suitable projecting position by a spring, so that by the latch wedge projecting
from the edge of the door coming in contact with the said catch on closing the
door, the catch recedes and allows the wedge to pass, the catch then holds the door
by the projecting portion of the wedge, until the latter is drawn into the door, by
which it is released.
In order that my invention may be fully understood, I will describe the same
by making reference to the accompanying drawings in which
Fig. 1. represents a sectional plan view of a carriage door and frame fitted with
my improvement, the door being closed.

page_text: Fig. 2. is a similar view showing the door held partly closed by my safety catch.
Fig. 3. a similar view showing the door open clear of my safety catch.
Figs. 4. 5. and 6. are detached details of the safety catch.
Into the door pillar A. I secure the catch frame B. containing the catch C. kept
in a protruding position by the spiral spring D. so that on closing the door E. a
distance sufficient for the projecting part of lock bolt F. to pass the catch C. the
door E. is so held that it cannot fly open.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that I am
aware that striking plates having a second or outer recess to retain a latch bolt 1
have previously been proposed, and I therefore make no claim to the use of a
catch excepting in the combination described but what I claim is :-
A safety catch as and for the purpose as hereinbefore described.
