I RALPH SLAZENGER Moss trading as Slazenger and Sons of 50 Cannon Street
in the City of London Merchant, do hereby declare the nature of my Invention
for IMPROVEMENTS IN THE APPLICATION OF MAGNETIC FORCE TO THE CLOSING OF
DOORS, BOXES, HAND-BAGS AND SIMILAR USEFUL PURPOSES, to be as follows:-
The object of my invention is to provide convenient substitutes for ordinary
locks, latches and other fastenings to doors, boxes hand bags and analogous articles
& things by using and applying magnets or magnetised portions of such articles,
having sufficient force to keep the same closed, when desirable.
In carrying out my invention I make use of permanent magnets.
In applying my invention to doors, I usually insert a magnet in the door-jamb,
in a convenient position, and in like manner, fit into the corresponding part of the
door a bar of steel-When the door is closed the magnet and steel are in contact,
or nearly so, and the door is thereby held in such position until opened by hand.
The magnet also causes the complete shutting of the door, when left slightly
open.
The magnet and steel bar may be fixed to the door in any convenient mannor
for effecting the purpose, the number being also sometime increased.
In applying my invention to bags and other articles, of a similar kind and also
such purposes as the closing of albums, pocket books, purses & and its application
to gaiters and leggings I find it advantageous to magnetise one of the steel bars or
frames which form the framing to the opening of the article and which, when
closed, is in contact with the corresponding steel bar or frame on the opposite side,
and whereby it is retained in a closed position under ordinary usage until it is
opened by hand.
Instead of magnetising the frame itself, magnets and keepers may be attached to
the frame in any convenient manner.
In applying my invention to small metallic boxes, one side, or a portion of one
side is formed of magnetised steel, a corresponding portion of steel being provided
on the opposite side.
It is obvious that, with slight modifications to adapt my invention to the nature
of the article, it may be applied to many things in ordinary use, especially those
which require frequent opening and closing; thus rendering unnecessary the
ordinary catches and locks, which, by frequent use, become defective and cause
annoyance.

I RALPH SLAZENGER Moss, trading as Slazenger and Sons, of 56 Cannon Street,
in the City of London, Merchant, do hereby declare the nature of my Invention
for "IMPROVEMENTS IN THE APPLICATION OF MAGNETIC FORCE TO THE CLOSING OF
DOORS, BOXES, HAND-BAGS, AND SIMILAR USEFUL PURPOSES and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-

The object of my invention is to provide convenient substitutes for ordinary
locks, latches and other fastenings to doors, boxes, hand-bags gloves, armlets and
analogous articles and things, by using and applying magnets or magnetised
portions of such articles, having sufficient force to keep the same closed, when
desirable.
In carrying out my invention I make use of permanent magnets.
In applying my invention to doors, I usually insert a magnet in the door jamb,
in a convenient position, and, in like manner, tit into the corresponding part of the
door a bar of steel, which is used as an armature to the magnet. When the door
is closed the magnet and armature are in contact, or nearly so, and the door is
thereby held in such position until opened by hand.
The magnet also causes the complete shutting of the door, when left slightly
open.
The magnet and armature may be fixed to the door in any convenient manner
for effecting the purpose, the number of magnets and armatures being also increased,
to afford greater power when necessary.
In applying my invention to bags, and other articles of a similar kind, and also
to such purposes as the closing of albumns, pocket books, purses &c. and its
application to gaiters and leggings I find it advantageous to magnetise one or
more of the steel bars or frames which form the framing to the opening of the
article and which, when closed, is in contact with the corresponding steel bar or
magnetized frame on the opposite side, and whereby it is retained in a closed
position under ordinary usage, until it is opened by hand.
Instead of magnetising the frame itself, magnets and armatures or two or more
magnets may be attached to the frame in any convenient manner.
In applying my invention to small metallic boxes, one side, or a portion of one
side is formed of magnetised steel; a corresponding portion of steel being provided
on the opposite side, or both sides may be magnetised.
It is obvious that, with slight modifications to adapt my invention to the nature
of the article, it may be applied to many things in ordinary use, especially those
which require frequent opening and closing; thus rendering unnecessary the
ordinary catches and locks, which, by frequent use, become defective and cause
annoyance,
And in order that my said invention may be particularly described and
așcertained, reference is hereby made to the accompanying drawings, in which

page_text: similar letters of reference indicate corresponding parts; and which drawings are
intended as illustrations of one method of carrying out my invention, as applied to
doors.
Fig. 1 is an elevation of a portion of a door jamb, being an edge view, and Fig. 2
is a side view of the same. Fig. 3 is a horizontal section on the line a b of Figs. 1
and 2. e is the door jamb, is the magnet, mortised into the door jamb e, as
shewn. g is the door, which as an armature h firmly fixed thereto.
When the door is nearly closed, as shown in Fig. 3, the magnet fattracts the
armature in the direction shewn by the double arrow, the power increasing
until actual contact takes place, when it is most powerful.
In fitting my invention to double-acting swing doors the bead or projection e¹ is
omitted, and the door jamb and magnet are made flush to allow the door to swing
inwards and outwards.
Another method of fitting the magnet is shewn in Figs. 4 and 5, Fig. 5 being a
section on the line c d of Fig. 4.
From the foregoing description and illustrations, it will be obvious that the
numerous applications of which my invention is capable are very great and varied,
and I do not confine myself to those shewn on the drawings, as they are, in all
cases, constructed according to the object for which it is to be applied.
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. The application and use of the magnetic force of permanent magnets to the
closing of doors, boxes, hand-bags, gloves, armlets, and analogous articles and
things, substantially as and for the purposes herein before described and partially
illustrated on the drawings.
2. The application and use of magnetised frames or portions of the frames of
bags, albums, pocket books, purses, gloves, armlets, gaiters and leggings, sub-
stantially as herein before described.
3. The application and use of magnetised sides lids, or other convenient parts of
boxes, substantially as described.
4. The general arrangement and application of magnetic force, constituting and
forming my improvements in the application of such force to the closing of doors,
hand-bags and similar useful purposes, substantially as herein before described and
partially illustrated on the drawings.
