HENRI DAELMANS Cabinet Maker 49 & 50 High Street Portland Dorset do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to a locking bolt for doors, gates windows and the like,
the object being to provide means for either bolting, or for further security locking
doors, gates windows and the like by use of the locking bolt, and so dispense with
padlocks and ordinary bolts & locks. The invention consists of a sliding bolt
working horizontally or vertically upon an oblong plate large enough to contain
the ordinary fittings of a lock.
Attached to the bolt is a locking plate which shuts into the lock; & when locked
the locking plate covers the screws for fixing the lock. to door gate window or the
like and thus prevents the removal of the locking bolt. When so required the
bolt can be slid back, and the locking plate shut into back part of the lock, and
locked, by this arrangement it is impossible to use the bolt or lock without the
key.
The locking bolt can he applied for sliding doors, sashes & the like by having
the end of bolt made to an oval section, then by lifting the locking plate to an
horizontal position and sliding it in the required direction the oval shaped end of

page_text: bolt would enter a similar shaped hole in plate fixed at side of door or sash, the
locking plate would then be shut into lock, the shoulder at junction of circular
section with oval section of bolt would prevent the door or sash being opened.
The locking bolt is double handed and will suit any door window or the like.
A special feature of this invention is its simplicity of action.
The locking bolt has no detachable parts and being an article of simple manu-
facture can be produced at a small cost.
In order that this invention may be clearly understood I refer to drawings left
with the Provisional Specification which drawings are marked with figures &
letters of reference corresponding with the following explanation thereof.
Sheet 1 Fig 1 is an elevation of the locking bolt shewing the bolt locked. Fig 2
is section showing by dotted lines position of locking plate B when unfastened.
A is the bolt arranged to suit either a right or left handed door, window or the
like. B is the locking plate so arranged that when locked two of the screws C
are covered.
The guides E with case I and lock fittings are all securely attached to plate F.
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.
1. A sliding bolt with locking plate attached arranged to slide to the right or
left, end of bolt may be oval shaped for use with sliding door sash or the like
substantially as and for the purpose hereinbefore described.
2. Plate for fixing to doors sashes or the like with, guides for bolt, lock fittings
and case attached substantially as and for the purpose hereinbefore described.
Dated this 26th day of November 1897.
