spring g¹ brings the catch bolt K back to its normal position. On turn-
ing the key in one direction the lock bolt e is brought in front of the
pin d and the bag is locked, because the pin d is stopped in moving in
the slot and with it the catch bolt K; on turning the key in the 2
opposite direction the lock bolt leaves the pin free, and the spiral spring

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Gustav Lüttringhaus, Her special licence
that I, the said Gustav Lüttringhaus, my executors, administrators, and
assigns, or such others as I, the said Gustav Lüttringhaus, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during 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 "AN IMPROVED LOCK
FOR TRAVELLING BAGS, APPLICABLE ALSO TO OTHER PURPOSES," upon the condition
(amongst others.) that I, the said Gustav Lüttringhaus, 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 Gustav Lättringhaus, do hereby
declare the nature of my said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of my Invention is to provide a convenient lock opening
by stud or key, that is to say, simply catching or locking at pleasure
and keeping the two sides of the mouth of the travelling bag close
against each other in their entire length when the bag is closed.
On the accompanying Sheet of Drawing, Figure 1 represents a
travelling bag furnished with a lock embodying my Invention. .
Figure A being an elevation of said lock set on an opened travelling
bag frame; 6 indicating the stud for opening bag when not locked by
key in boss c; M, catches, Figure B is a plan of lock plate detached, and
Figure C elevation of same; a, slot in which the stud 6 traverses to and
fro; c, boss riveted on lock plate with hole to receive key. Figure D,
slide carrying stud b and pin d in connection with catch bolt K; Figure
E, plate upon which lock plate B is riveted. Figures F and G, box
holding lock bolt e; f, slot through which the pin d passes, and in which

page_text: it travels to and fro; g, plate in connection with lock bolt e and spiral
spring g' (see Figures G and L). Figure H plan view of slotted plate
into the slots of which pass the hooks or catches. Figure I end view
of same. Figure K, catch bolt working in plate H. Figure L, sectional
elevation showing entire arrangement of lock.
Action of this improved lock.-On pushing the stud 6 along its slot
it carries with it the slide D, which compresses the spiral spring and by
means of the pin d draws the catch bolt K from beneath the head of
the catches M and permits the opening of the bag; upon releasing the
stud 6 the spring g' brings the catch bolt K back to its normal position.
On turning the key in one direction the lock bolt e is brought in front
of the pin & and the bag is locked, because the pin d is stopped in
moving in the slot and with it the catch bolt K; on turning the key
in the opposite direction the lock bolt leaves the pin free, and the spiral
spring by means of the plate 9 keeps the lock bolt e in its normal
position.
Figure 2 represents a bag fitted with a modification of my improved
lock. It will bo observed that when the bag is closed one side of the
mouth comes under the other instead of their sides simply meeting each
other as at Fig. 1.
Figure M shews the lock and bolt fitted on to an open bag frame; his
the stud for opening the bag when not locked by the key in boss i; j,j,
catches which enter the slots k, k, in catch bolt i; q, q, guides for
catch bolt 1, l. Figure N is a plan of lock case detached from frame.
Figure O an elevation of same; m, slot in which stud / works; i, boss:
riveted on lock casc. Figure P is the slide to which are attached the
stud and pin n. Figure Q, plan and elevation or side view of lock
bolt on which is the stud o. Figure R represents a longitudinal section
through the lock, showing internal arrangement of lock; 8, spring to
keep lock bolt in place. Figure S is the catch bolt in which are the two a
slots k, k, for receiving the catches j,j, and also a third slot p into
which the pin » enters,
•
Action of this lock.-On pushing the stud along the slot it carries
with it the slide P, which compresses the spiral spring », and by means
of the pin n draws the catch bolt 1, 2, from beneath the head of the
two catches j, j, and permits the opening of the bag; upon releasing
the stud the spring brings the catch bolt back to its normal
position. On turning the key in one direction the stud o on the lock

page_text: bolt
q is brought in front of the slide P and thus locks the bag; on
turning the key in an opposite direction the lock bolt leaves the slide P
free to move. The lock first above described has four catches, and two
slotted plates (the movable plate K and the fixed plate H); the second
has but two catches, (j,j,) and one slotted plate (4); the pieces q, q,
securing plate in position as that H does plate K. I need scarcely
observe that any number of catches may be used taking into a corre-
sponding number of slots. The construction of the second lock itself
also differs internally, for instead of the lock bolte and plate 7 (see
Figures F and G) there is the circular bolt Q on which is the stud o
and the spiral spring 8, and from the construction of the plate or bolt Q
this arrangement is far less liable to be picked. It will however be
apparent that although differing in details these two locks embody a
same principle of construction, that is to say, the stud b, slide D, spiral
spring g', pin d, and catch bolt K of Fig. L find their equivalents in
stud h, slide P, spiral spring r, pin n, and catch bolt u of Fig. R. I
need scarcely observe that my improved lock is not only applicable to
travelling bags, but also to dressing cases and a variety of analogous
articles.
Having now described and ascertained the nature of my said Inven-
tion, and in what manner the same is or may be performed, I would
have it distinctly understood that I construct my improved lock of any
metal or material which I may find suitable, that I do not limit myself
to any particular shape or dimensions of the lock or of its parts, that the
actual locking mechanism from c or i may be varied while retaining the
combination constituting my Invention, and that what I claim as secured
to me by the herein-before in part recited Letter Patent is, the com-
bination of stud b, and slide D, spring g', pin d, and catch bolt K or
their equivalents with each other, and with a locking arrangement,
substantially as and for the purpose herein-before set forth.
In witness whereof, I, the said Gustav Lüttringhaus, have herec-
unto set my hand and seal, this Fifth day of October, in the year
of our Lord One thousand eight hundred and seventy-two.
GUSTAV LÜTTRINGHAUS. (L.S.)
