ROBERT BATEY, 17 Jessamine Terrace, King Cross Road Halifax, Yorkshire,
Estate Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in door locks whereby the face or front
plate to lock is also made so as to answer the purpose of a box or receptacle for a
door guard chain attached stud to work in, also the box staple for lock bolt and
hasp has the door guard chain connected to same. In carrying out this invention,
I make the face or front plate of lock with a groove or oblong hole in same, this is

Improvements in Door Locks.
ROBERT BATEY, 17 Jessamine Terrace, King Cross Road, Halifax, Yorkshire,
Estate Agent, 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 :-
This invention relates to improvements in door locks, whereby a door guard
chain may be combined and used in conjunction therewith.
In carrying out this invention, I make the face or front plate of the lock with a
groove or oblong hole, for the reception of the stud attached to one end of the door
guard chain. This stud can then be inserted, moved along, or withdrawn, as may
be desired. Or instead of making a groove or oblong hole in the front plate of the
lock, I may use a separate plate with a groove or oblong hole in it, and I may
or attach this separate plate to the front plate of the lock, so as to leave a space
between them, for the free movement of the door guard chain stud. The other end
of the door guard chain I may attach to the box staple, which receives the bolt of
the lock.

Fig. 1. of the accompanying drawing, shows a lock constructed in accordance
with this invention. A. is the front plate of the lock, with a groove or oblong
hole B in its lower portion. The guard chain C is attached by one end to the box
staple D, and the stud E, at the other end of the chain, can be inserted in the
groove B.
Figs. 2 and 3 show the groove or oblong hole made in a separate plate F,
which plate is fixed to the front plate A of the lock by any suitable means,
such as screwing or riveting. Fig. 2 shows a front view, and Fig. 3 a view from
underneath.
1 am not bound to use the exact positions shown in the drawings for the groove
or oblong hole. I may place it in any convenient part of the cover of the lock, at
the top, bottom, side or front, or at any convenient angle.
