USE OF A TUBULAR BOLT IN DOUBLE ACTION LOCKS FOR TRUNKS, PORTMANTEAUS, FOLIOS, DOORS AND OTHER PURPOSES
Year: 1885

page_text: We HAYDN SANDERS of 20 Victoria Road, Bloxwich, Locksmith and THOMAS
SANDERS High Street Bloxwich Grocer & Lock Manufacturer do hereby declare the
nature of our invention for THE USE OF A TUBULAR BOLT IN DOUBLE ACTION
LOCKS FOR TRUNKS, PORTMANTEAUS, FOLIOS, DOORS AND OTHER PURPOSES, to be
as follows:
All double action lock contemplated by us, for the use of our Tubular Bolt, have
two bolts, a latching bolt and a locking bolt. The latching bolt is worked by
various methods, such, for instance, as in the case of a Trunk lock by pushing or
pulling the nozzle aside. And in that of a door lock by the turning round or
pushing aside of the knob. Such is the action of a latching bolt.
The locking bolt is that which is worked only by a key; and the action of the
same in the case of a door lock is simply the locking over of the only security
which the lock possesses, as it as no connection with the latching bolt, for such
can still be moved as before. In the case of a Trunk or Folio lock the action is
sometimes different As for instance the latching bolt in some cases is the only
bolt visible; and in fact the only bolt which is relied upon so far as regards strength
or strain: the locking bolt in this case is simply used to prevent the other from
being drawn back. They are also made in Folio lock on exactly the same principle
as the door lock described. In fact we can find no double action locks where there
is protection given by a Tubular Bolt and therefore all other ways must leave, as
in the above mentioned cases, one action not used, or at least only part used.
Either the latching action is left as a latch-and therefore valueless as a protection,
or the latch bolt is entirely depended upon for safety and hence the locking action
is used to make it so.
Though tis true the locking power is wasted.
In all the examples if our Tubular Bolt were adapted the actions are entirely
different.
For it will be seen immediately that the latching bolt would lend increased
support to the locking bolt, and vice-versa. Whilst it is impossible to injure the
latching bolt after the locking bolt has been moved across by the key, as in the
other examples.
The principle on which our Tubular Bolt is founded is contained in the following
example; on which we have constructed our model,

page_text: Our latching bolt is made at the head (that is, all that is visible from an external
view) an inch square, and our locking bolt is 1 in square at the head. Up the
centre of the locking bolt a hole is made just large enough for our latching bolt to
slide up and down. So that when the locking bolt is moved out by the key it as
the appearance of one solid bolt; and is to all intents and purposes nearly such,
for the tubular space is of course filled up by the latching bolt. It is therefore
manifest that no injury can come to the latching bolt for it is entirely hidden from
view. And to make such latching bolt lend support we have so arranged our
tubular bolt that when it is locked out the latching bolt is entirely prevented from
being moved by the knob, nozzel, or other agent.
On the above description of our invention we base our claim for Letters Patent
to be issued to us.

HAYDN SANDERS, Locksmith, 20, Victoria St, Bloxwich, THOMAS SANDERS
Grocer & Lock Manufacturer High Street Bloxwich do hereby declare the nature
of our invention for THE Use of a TubuLAR BOLT IN DOUBLE ACTION LOCKS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
All double action locks contemplated by us for the use of our Tubular Bolt have
two bolts, a latching bolt and a locking bolt.
The latching bolt is worked by various methods, as for instance in the case of a
Trunk lock by the pushing or pulling the nozzel aside, and in that of a door lock
by the turning round or pushing aside of the knob. Such is the action of a latching
bolt. A locking bolt is that bolt which is worked only by the key; and the action
of the same in the case of an ordinary door lock is simply the locking over of the
only security which the lock posesses as regards strength, for it as no connection
with the latching bolt for such can still be moved as before by the knob.
In the case of Trunk or Folio locks the action is sometimes different, as in the
accompaning Sketch of a Trunk lock, the latching bolt (fig 2) is the only bolt
visible, and in fact is the only bolt which is giving strength, for the locking bolt in
such case would only be used to prevent such latching bolt from being drawn back
by the nozzel or other agent.
In all cases that we have come in contact with either one bolt or the other have
been relied upon, whilst the other has been next to useless as regards strength; for
in no case does the locking bolt lend strength to the latching bolt or vice-versa.
It remains for our Tubular Bolt to affect this, as will be seen from the accompanying
drawings and this our discription.
Plate A represents the ordinary double action Trunk lock (with nozzle to push
aside) and the latching bolt (fig 2) is the only means of strength.
Figure 3 is our Tubular Bolt, which it will be seen is made proportionately
larger than the latching bolt (fig 1-2) for it as for its function the entire encasing
of the head of the latching bolt, as shewn in fig 4, Figure 5 give an end view of
our Tubular Bolt with the latching bolt inside it; whilst Plate B gives a view of
our Tubular Bolt after it has been moved across the hasp hole by the key. Thus
our double action lock contains two bolts which render strength to each other, for
not only does our Tubular Bolt render strength in itself, but it also retains and
contains the whole strength of the latching bolt for by simply fixing a stopper on
the locking bolt (that is our Tubular Bolt) at the distance required according to the
travel of the latch bolt, it prevents the said latch bolt from being drawn back by
the nozzel, and at the same time such latching bolt cannot be injured, for it is, as
before stated, entirely encased by the tubular bolt.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
The use of a Tubular Bolt in all kinds of double action locks where such is
applicable.
