A SO-CALLED DIANA LOCK, OR IMPROVED FASTENING
Year: 1857

page_text: LETTERS PATENT to Joseph Schloss, of 75, Cannon Street West, City,
Merchant, for the Invention of "A SO-CALLED DIANA LOCK, OR IMPROVED
FASTENING."
Sealed the 23rd April 1858, and dated the 24th November 1857.
PROVISIONAL SPECIFICATION left by the said Joseph Schloss at the
Office of the Commissioners of Patents, with his Petition, on the 24th
November 1857.
J, JOSEPH SCHLOSS, of 75, Cannon Street West, City, Merchant, do hereby
declare the nature of the said Invention for "A SO-CALLED DIANA LOCK, OR
IMPROVED FASTENING," to be as follows:-
This new mode of fastening, otherwise called Diana lock, from the upper
part of its tumbler or trigger plate having the shape of a half-moon or
crescent, may be worked by hand for bolting only, or by key both for bolting
and locking. It is applicable to dressing cases, travelling bags, pocket books,
books, porte-monnaies, cigar cases, cases of surgical instruments, trunks, and.
even immoveable objects. Its use, however, is calculated chiefly for small
portable articles.
Its chief parts are,
1st, the case of the lock (of any suitable dimensions) fixed by rivets, or any
other means, to one part of the frame or object to be fastened, and having the
required keyhole at the outside of the plate.

page_text: 2nd, a tumbler or trigger plate having the shape of a segment of a circle,
with a suitable opening for the keyhole, and a cam, which is to be worked
upon by another part of the lock.
3rd, a catch spring, fixed by one end at the outer frame, and by the other
at the above segment plate, and having a suitable bent or curve for the
catch.
4th, a bolt plate placed inside the case and below the keyhole, upon a
small rod, or otherwise. This bolt plate contains two horizontal openings,
and a suitable notch for the working of the key. It contains also a cam
corresponding to the cam of the tumbler or trigger plate.
5th, a plate covering the above case, and containing two pins, which enter
into the above two horizontal openings of the bolt plate for working the same
in a straight line by the action of the key.
6th, finally the catch fixed on the side of the frame opposite to that side on
which the above lock is fixed.
The mere bolting by hand takes place by pressing together the two parts
or frames to be fastened, whereby the catch enters into the spring catch. The
unbolting by hand is effected by pressing down the catch spring by means of
the trigger plate, whereby the catch is set free. In locking by key, the cain
of the bolt plate is brought under the cam of the tumbler or trigger plate,
whereby the working of the catch spring is prevented. Instead of cams on
one side of the tumbler or trigger plate and bolt plate, cams on both sides of
the same may be used.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Schloss in the Great Seal Patent Office on the s
6th May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
SCHLOSS, of 75, Cannon Street West, City, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of November, in the year of our
Lord One thousand eight hundred and fifty-seven, in. the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Schloss, Her special licence that I, the said Joseph Schloss,
my executors, administrators, and assigns, or such others as I, the said Joseph
Schloss, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during:

page_text: the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, .the Channel
Islands, and Isle, of Man, an Invention for "A SO-CALLED DIANA LOCK, OR.
IMPROVED FASTENING," upon the condition (amongst others) that I, the said
Joseph Schloss, my executors or administrators, by an instrument in writing
under my or their or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Joseph Schloss, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
.
The object of this Invention is the construction of a kind of fastening,
otherwise called Diana lock (from the upper part of its tumbler or trigger
plate having preferably the shape of a half-moon or crescent), which may be
worked by hand for bolting only, or by key both for bolting and locking.
The annexed Sheet of Drawings represents or illustrates the way in which
the same is worked and used. The same letters of reference stand for like ⚫
parts in the different figures.
Fig. 1 represents the mounting or metallic frame of an open travelling bag
provided with the tumbler or trigger plate c; a being the metallic frame or
exterior inounting; d, a curved spring blade, rivetted or screwed by one end
to the frame a, and by the other to the segment c; j, a pin or gudgeon
fixed on that side of the frame a which is opposite to the lock into which it
enters.
Fig. 2 represents the inside of the lock when open; Fig. 3 represents the
inside of the lock when locked, its cover being removed.
is the main plate or box containing the various parts of the lock; it is
made of any convenient size, and rivetted or screwed to the frame or case,
bearing the keyhole on its outside plate or scutcheon; c, tumbler or trigger
plate, with curve and cam, its dimension at the upper part admits of its
entering into the box or main plate; at its upper part it has a projection
outside the frame a; d, a spring blade, as mentioned before in Fig. 1; e, bolt
below the keyhole, with two horizontal long slots or openings, and a notch
upon which the key is working; f, cam at the upper part of the bolt e;
9, rod or spring, resting on the lower part of the main plate or box, and
supporting the bolt c.

page_text: Fig. 4, h, cover of the main plate or box, scrowed or worked on the same;
i, i, pins rivetted on the plato h, and entering into the horizontal slots or
openings of the bolt e, for guiding the same, and keeping it in a straight line
when worked upon by the key.
The manner of working the above-described lock is the following:-The
two parts of the frame a being brought together, the gudgeon jenters into
the lock, and catches the curved part of the spring blade d, whereby the bag
or other object is bolted. A mere pressure on the upper part of the trigger
plate suffices to open it, by bending the spring d, and loosening the
gudgeon j. The locking is effected by turning the key half way, whereby
the bolt e and its cam fis brought under the cam of the trigger plate, so as
to render the lowering of the said plate impossible. The unlocking is effected
by turning the key half way in the opposite direction, whereby the bolt e is
brought to its former position, when it no longer prevents the depression of
the trigger plate c, and the loosening of the spring d. Instead of one single
cam on the bolt and trigger plate, as described before, two cams may be used,
one on each side of the keyhole.
Having thus described the nature of my Invention, and the manner in
which the same is or may be carried into effect, wish it to be understood.
that I do not confine myself to the exact size and shape of the lock as herein
described, since the same may be altered and modified without detriment to
the principle; but what I claim as the novel principle secured to me by the
herein-before in part recited Letters Patent is, the construction of the various
parts of a lock, as described above, and applicable chiefly to dressing cases,
travelling bags, working bags, pocket books, books, porte-monnaies, cigar
cases, portemanteaux, furniture, etc., and also to immoveable objects, such as
windows, doors, etc., its chief features being bolting or locking by means of
a tumbler or trigger plate, with one or two cams acting on a bolt, with one or
two cams for catching or loosening the gudgeon of the lock.
In witness whereof, I, the said Joseph Schloss, have hereunto set my
hand and scal, this Sixth day of May, in the year of our Lord One
thousand eight hundred and fifty-eight.
JOSEPH SCHLOSS. (L.)
