I, LEOPOLD HABERER of Freiburg, Baden, in the German Empire, Merchant,
do hereby declare the nature of this invention. to be as follows:-
The lock of this invention is designed for mounting on books which it is desired
to guard against unauthorised opening. It consists of two side clasps one of which
carries at each extremity a hollow sleeve projecting therefrom and the same clasp
also carries projecting in the same direction from its central part a hollow sleeve
which is slotted along its length. This latter sleeve has mounted upon it a number
of rollers provided on their circumference with letters of the alphabet. All the
letter rollers have a slot in their bore, which slots correspond to the slot in the
hollow sleeve upon which they are mounted. The other clasp is provided with two
pins and with a central toothed bar projecting therefrom. The two pins slide in
the two corresponding sleeves and the central rack or toothed bar slides partly in
the central slotted sleeve and partly in the slots of the letter rollers and when one
or more of the letter rollers are turned partly round from this open position the
unslotted part of their bore will take in between the teeth and engage them in the
locked position. To open the lock and the book it is necessary to turn all the letter
rollers into such a position that the slots of all the said rollers come into line, say,
so that the letters shall form one or more particular. words only known to
authorised persons. The covers of the book are fitted with mountings against
which the clasps bear when the book is locked, the said covers and mountings
being perforated to allow of the passage of the parts projecting from the clasps.
The lock may also be arranged to lock the book through staples or eyes projecting
from the inner edges of the covers.

1, LEOPOLD HABERER of Freiburg, Baden in the German Empire, Merchant,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to lock up books such as account books, letter books,
etcetera. The invention consists in the combination of a permutation lock with the
book covers, which latter are provided with holes, eyes, or loops, through which are
passed the pins and sleeves of two separable locking parts of the permutation lock,
said pins being slideable within the sleeves and the two locking parts held together
by letter rollers that may be turned round upon one of the locking parts to

page_text: engage by an edge in teeth of the other locking part, but are not longitudinally
displaceable, and the object of the invention is to prevent the opening of such books
by unauthorised persons.
In the drawing, in which similar letters of reference indicate like parts,
Fig. 1 is a front edge view of a book fitted with the lock.
Fig. 2 shews one of the side plates of the lock.
Figs. 3 and 4 are sectional views of the lock parts respectively in the open and
closed position.
Fig. 5 is a cross section through line A-B of Fig. 3.
Fig. 6 a cross section through line C-D of Fig. 4, and Fig. 7 shews the lock
arranged in another way relatively to the book.
A indicates the assembled leaves of the book. B the book covers. C mountings
on the covers which form the side plates of the lock. D, E, the locking clasps.
The part D consists of a clasp plate at the centre of which is fixed a longitudinally
slotted sleeve L and at each end a sleeve H. The part E consists of a clasp plate
at the centre of which is fixed the toothed rack N and at each end a pin G. The
rack N. is of a cross section corresponding to the slot in the sleeve L so that the
rack may be slid and guided along the longitudinal slot of said sleeve when
the parts D and E are moved towards or away from one another (Fig. 3). The
pins G are of a cross section corresponding to the sleeves H so that the pins may be
slid and guided to an fro within the sleeves when the parts D and E are moved
towards or away from one another. Upon the slotted sleeve L are mounted
rollers K provided on their outer circumference with letters, and internally with a
recess ✗, which rollers may turn upon said sleeve but may not be laterally
displaced over the outer edge or shoulder of the same. The recesses X of all the
letter rollers form, when these are in a certain position with their letters forming a
secret or pass word, a straight channel in which the toothed rack N, projecting to
some extent out of the slot of the sleeve L, may be slid. If only one of the
rollers K should be turned round from this position to take with its full or
unrecessed part of its edge between two of the teeth of the rack, then the passage
or channel for the rack is obstructed and the parts D, E, can no longer be
separated from one another, and the rollers themselves cannot be removed from
the sleeve L. The position of the lock relatively to the book or to the covers may
vary as desired. A different position of the same is shewn by way of example in
Fig. 7. In this case, loops or eyes y are attached to the covers, and pins G and
sleeves H passed through said loops or eyes, the clasps or locking, plates D, E, then
being horizontally placed.
To lock up the book the locking clasp D is taken in the hand, the sleeves H
passed through the holes F in one of the covers of the book, the letter rollers K
then so placed as to bring their recesses into line and compose a secret word or
pass word, for instance the word." Pastor" as shewn in Fig. 1, the recesses X of
the rollers then forming a straight channel. The pins G of clasp E are then passed
through the holes F in the other cover of the book and into the sleeves H, the
rack N being at the same time introduced into the slotted sleeve L so that the
teeth of the rack project outwards beyond the slot in the same. This outwardly
projecting portion of the rack takes into the channel formed by the recesses X of
the rollers K. After the pins and rack of clasp E have been passed respectively
into the sleeves H, H, and L, the letter rollers are turned so that the full or
unrecessed part of their sides comes to stand between the teeth of rack N. The
book is then in the locked position, as the clasp E cannot be drawn away from the
clasp D because the rack N is held fixed by the rollers K and these cannot be
removed from the sleeve L.
The book may be unlocked by returning the letter rollers K to their previous
position in which the word "Pastor" was presented to view as described, in which
position the recesses X form a straight channel releasing the rack N so that the
two locking clasps D and E may be separated or drawn away from one another.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A permutation lock up book provided in both of the covers with holes or eyes
through which pins G and sleeves H of two clasps D, E, of a permutation lock are
passed, and pins G slid into sleeves H and fixed together by the inner edges of the
letter rollers K taking between the teetb of the rack N of clasp E, said letter
rollers being mounted to turn upon the slotted sleeve L of clasp D but not being
laterally displaceable thereon, substantially as described and shewn.
