IMPROVEMENTS IN LOCKS & BOLTS
Year: 1884

page_text: I WILLIAM CATHLEWGH JONES of 26 Duke St. Chester in the county of Chester
Fellmonger do hereby declare the nature of my said invention for IMPROVEMENTS
IN LOCKS & BOLTS to be as follows that is to say:-
This invention relates to improvements in the constructions of Locks whereby
the Bolt of the lock shoots out by the force of gravitation instead of by the aid of
springs as in those of ordinary construction.
In carrying out my said invention I employ a bolt which is approximately a
Quadrant with one arm or bar running from the centre to the circumference and
fastened thereto thus
لا
The Radial arm may be in any position either higher or lower than the centre
of the Quadrant.
One end of the Quadrant passes through the rim of the lock and forms the Bolt
and the other end is at liberty to move up and down as the bolt slides in and out,
unless prevented by the bolt of a small lock (placed behind this large bolt) &
sliding out between it & the top rim of the lock The handle of the lock engages
by means of a small lever with a slot in the before mentioned quadrant so that
unless locked by the before mentioned small bolt the large bolt can be slided back
always returning however by the action of gravitation.

page_text: I WILLIAM CATLEWGH JONES of 26 Duke Street in the City and County of
Chester, Fellmonger, do hereby declare the nature of my said invention for
IMPROVEMENTS IN LOCKS AND BOLTS, 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 the construction of Locks and Bolts
whereby the bolt of the Lock shoots out by the force of gravitation instead of by
the aid of springs as in those of ordinary construction.
In carrying out my said invention I employ a bolt which is approximately a
Quadrant with an arm or bar running from the centre to the circumference and
fastened thereto thus:-
D
The radial arm may be in any position either higher or lower than the centre of
the Quadrant.
One end of the Quadrant passes through the rim of the lock and forms the bolt
and the other end is at liberty to move up and down as the bolt slides in and out
unless prevented by the Bolt of a small lock (placed behind this large bolt) and
sliding out between it and the top rim of the lock.
The handle of the lock engages by means of a small lever with a slot in the
before mentioned Quadrant so that unless locked by the before mentioned small
bolt the large bolt can be slided back always returning however by the action of
gravitation.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a Section through
the rim of the Lock.
A is a bolt which swings from the centre D and by its own gravitation causes
the end H to project through the rim F.
E is a small lock of ordinary construction and B is the bolt belonging to same.
When the bolt B is out as shown in the drawing the bolt A is prevented from
moving, and is consequently locked.
When however the bolt B is drawn in the large bolt A may be moved by the
small lever C to which the handle of the door is fastened.
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
Firstly. The construction and employment of a Lock in which the main bolt
slides out by the force of gravitation without the employment of springs substantially
as described-and
Secondly The use of an ordinary small lock in combination with the aforesaid
bolt by which it is prevented being drawn back, and securely fastened when so
required thus rendering necessary only one bolt projecting from the lock
substantially as described.
