Improvements in Fastenings for the Doors of Flues or Fire Places.
1, JOSEF HOHENREINER of Augustastrasse 41, Munich in the Kingdom of
Bavaria and German Empire, Locksmith, do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to simple and effective means of fastening the doors of
flues or fire places and is specially applicable to doors having inner and outer
plates.
According thereto I employ a multi-armed bolt adapted to enter recesses in the
door frame and thus secure the door in its closed position.
In one arrangement there is provided at the inner side of the outer door plate a
bolt having a number of arms or branches cranked or bent at their outer or free
ends. The bolt is rigidly fixed to a pin or projection fixed to a disc or boss
supported in a rotary manner on the outer side of the outer door plate, the
arrangement being such that on partly rotating the said disc or boss (when the
door is closed) in one direction the cranked ends of the arms of the bolt will be
caused to take simultaneously in corresponding recesses provided in the door frame,
thereby locking the door securely in its closed position. On moving the disc or boss
back into its former position the door will be unlocked.
The accompanying drawings illustrate a flue or fire place door of the construction
referred to fitted with my improved locking device in which
Fig. 1 is an elevation;

covering the disc or boss and having formed in it a slot or recess. The disc or
bosse has a corresponding recess, in which is adapted to take a rod or bar
introduced through the slot in the cap c. On turning the bar or rod
direction of the arrow (Fig. 2), the door being closed, the consequent rotation of
the disc or boss in the same direction will cause the arms of the bolt to take into
recesses 11. n in the door frame m, and so lock the door. On turning the rod or
bar g in the opposite direction the arms of the bolt will be turned back out of the
recesses, thereby unlocking the door.

COMPLETE SPECIFICATION.
Improvements in Fastenings for the Doors of Flues or Fire Places.
I, JOSEF HOHENKEINER of Augustastrasse 41, Munich, Germany, Locksmith,
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 simple and effective means for fastening the doors of
flues or fire places and is specially applicable to doors having inner and onter
plates.

page_text: For this purpose I employ a bolt having several arms adapted to enter recesses
formed in the door frame and thus secure the door in its closed position. This bolt
is arranged at the inner side of the outer of the two plates constituting the door
and is rigidly fixed to a pin or projection fixed to a rotary disc or boss arranged
at the outer side of the said outer door plate the arrangement being such that on
partly rotating the said disc or boss in one direction after the door has been closed
the ends of the bolt arms which may be bent or cranked will be caused to take
simultaneously into corresponding recesses formed in the door frame, thereby locking
the door securely in its closed position, and on moving the disc or boss back into its
former position the door will be unlocked.
The drawings left with any Provisional Specification illustrate a flue or fire
place door of the construction referred to fitted with my improved fastening device.
Fig. 1 being a front elevation with the outer door removed.
Fig. 2 a front elevation partly in section and with the outer door in place; and
Fig. 3 a vertical section on the line ay of Fig. 2.
e is a cap

or hoss which terminates at its inner side in a pin d that passes through the plate a,
and is rigidly connected to and forms the axis of rotation of the bolt.
arranged to cover the dise or boss e and having formed in it a slot . The dise
or boss c has a corresponding recess & adapted to receive one end of a rod or bar g
when introduced through the slot in the cap e. On then partly turning the bar or
rod in the direction of the arrow (Fig. 2) the door being closed, the consequent
rotation of the disc or bosse in the same direction will cause the arms of the bolt /
to take into the recesses in the door frame m and so lock the door in its closed
position. On turning the rod or bar g in the opposite direction the arms of the
bolt will be turned back out of the recesses n thereby unlocking the door.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed declare that
what. claim is :-
:-
A fastening device for the doors of flues or fire places, comprising a multiple arm
bolt secured to a pin d fixed to a rotary disc or boss that is carried by the
outer plate a forming the door or part thereof, the arrangement being such that by
partial rotation of the disc or boss the arms of the said bolt will be caused to
simultaneously enter recesses formed in the door frame m and securely lock
the door in place substantially as hereinbefore described and
drawings.
