Improvements in and relating to Locks for Purses, Portfolios,
Letter-cases, and similar Articles.
I, FRIEDRICH LEHMANN of Offenbach on the Main, in the Grand-Duchy of
Hessen, German Empire, Manufacturer do hereby declare the nature of this
invention to be as follows :-
My invention relates to a lock for closing purses, portfolios, letter-cases and
all those similar articles, in which one half of the lock is fixed to the body of
the article, and the other half to a flap covering the openings of the separate
compartments; and my improvements in such locks relate to an arrangement
of one or two racks, in combination with teeth catching into said racks, so as
to afford the possibility of adjusting both these parts according to the quantity
of money, letters, or other objects contained within the said articles.
I have shown one mode of construction of my adjustable lock in the accompanying
drawings, in which a is the body of a purse, having the half b of the lock
fixed to it, and a¹ the flap, to which is fixed the other half 6' of said lock.
Part 6 has a longish cavity c, Fig. 3, to the long sides of which are secured
two small racks d d', forming between them a slit c¹. These racks do not
extend in the whole length of the cavity, so that the slit c¹ widens to an
entrance for the part of the cavity below the racks.
The shank e¹
of the button extends to the rear-side of flap a', and carries two teeth g g',
which are adapted to gear with the racks d and d¹.
Part 6 of the lock has a press-button e, held by a spring f.
Now, when introducing the teeth g g' into the cavity c through the entrance c³,
and when pressing during, this time on the button e, the teeth may be moved
to any desired place within the cavity, and may be fixed in any position by
letting the teeth ggl enter the spaces between the teeth of the racks, so that a
perfect and reliable closure may be attained at every point of the racks.

Improvements in and relating to Locks for Purses, Portfolios,
Letter-cases, and similar Articles.
I, FRIEDRICH LEHMANN, of Offenbach on the Main, in the Grand-Duchy of.
Hessen, German Empire, Manufacturer 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 :-
My invention relates to a lock for closing purses, portfolios, letter-cases and
all those similar articles, in which one half of the lock is fixed to the body of
the article, and the other half to a flap covering the openings of the separate
compartments; and my improvements in such locks relate to an arrangement of
one or two racks, in combination with teeth catching into said racks, so as to
afford the possibility of adjusting both these parts according to the quantity of
money, letters, or other objects contained within the said articles.

page_text: I have shown one mode of construction of my adjustable lock in the drawing
sent in with Provisional application, in which a is the body of a purse, having
the half of the lock fixed to it, and a' the flap, to which is fixed the other
half of said lock.
.
.
Part 6 has a longish cavity c, Fig. 3, to the long sides of which are secured
two small racks d d', forming between them a slit c'. These racks do not extend
in the whole length of the cavity, so that the slit c' widens to an entrance c¹
for the part of the cavity below the racks.
Part 6 of the lock has a press-button e, held by a spring f. The shank e
of the button extends to the rear-side of flap a', and carries two teeth g g',
which are adapted to gear with the racks d and d¹.
Now, when introducing the teeth g g¹ into the cavity c through the entrance c³,
and when pressing during this time on the button e, the teeth may be moved
to any desired place within the cavity, and may be fixed in any position by
letting the teeth g g' enter the spaces between the teeth of the racks, so that a
perfect and reliable closure may be attained at every point of the racks.
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 :-
1. In a lock for purses, portfolios, letter-cases and similar articles, the com-
bination with a rack or racks attached to the one half of the lock, of a tooth
or teeth attached to the other half of the lock, and adapted to gear with the
rack or racks at different parts of the latter, one or the other or both parts of
the locks having mechanisms adapted to hold the racks and teeth in gear with
each other, for the purpose as described.
2. In a lock for purses, portfolios, letter-cases and similar articles, the com-
bination with a rack or råcks fixed immovably to the one half of the lock, of a
tooth or teeth attached movably to the other half of the lock, and adapted to
gear with the rack or racks at different parts of the latter, said other half of
the lock having a spring or springs adapted to hold the racks and teeth in gear
with each other, for the purpose as described.
3. In a lock for purses, portfolios, letter-cases and similar articles, the com-
bination with a rack or racks secured to the one half of the lock, and having
its or their teeth directed to the rear side of the lock, of a tooth or teeth
secured to the other half of the lock, and adapted to gear with the rack or
racks at different parts of the latter, said tooth or teeth being constantly
drawn upwards by a spring arranged between it or them and a press-button,
for the purpose as described.
4. In a lock for purses, portfolios, letter-cases and similar articles, the com-
bination with two parallel racks d d¹ having their teeth directed to the rear of
the lock, and forming between themselves a slot c¹, of two teeth 9 9' adapted
to be pressed down by a button e, and to be pressed up again by a spring f, and to
be kept in gear with different parts of said racks, said slot widening at its upper
end to an entrance to the space c below the racks, for the purpose as described.
Dated this 15th day of May 1894.
