COMPLETE SPECIFICATION.
Improvements in connection with Locks.
We, ROBERT JOHN RICE, and HERBERT EDWIN WILLIS, Art Metal
Workers, Eagle Works, Hornsey, N. in the County of Middlesex, 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 an improved mode of securing doors by means of three
bolts shot simultaneously by the action of one key with wards, and is different to
an ordinary espagnolette bolt worked by a handle.
In the drawing annexed to our Provisional Specification, we show an ordinary
key lock bolt E with the two additional bolts B, B, one to enter a bracket fixed on
the upper rail of the door frame, and one to enter a hole in the floor, the lower bolt
having a roller F to ride upon the carpet, and so support the free end of the door,
which prevents the hinges being strained.
According to the drawing, Figure 5, lodged herewith, we pivot the bolts B, B,
by bell cranks A, A, to the usual lock bolt E in the same manner, except that they
are operated from one pin on the usual locking bolt E, and instead of fitting the
additional bolts to move on the inner side of the door, we arrange them in slot or
other holes in the thickness of the door, as indicated in Figure 5, so that the upper
of the two bolts B, B, can enter a hole in the upper rail of the door frame, the
whole thickness of the lock being within the thickness of the door. This plan
allows the roller F to be dispensed with, and produces great neatness.

page_text: The lock proper may be of the usual self locking action when the door is closed,
or the key may be necessary both for locking, and for unlocking the door.
It will be understood that by this invention, no handle for moving the bolts is
necessary, it being essential that a key be used for the opening operation.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
Operating additional bolts of key locking locks from the main bolt, as and in
the manner described and substantially as shown in the drawings.
