PROVISIONAL SPECIFICATION.
An Improvement in Counting and Registering Apparatus for Tills.
1, HENRY POTTIN of No. 35 Rue Lepeletier, Paris, France, Civil Engineer, do
hereby declare the nature of this invention to be as follows :-
In the Specification No. 3313 of 1883, of a Patent granted to John Imray for
an invention communicated to him by me from abroad, I have described apparatus
for counting and registering sums of money paid by customers in shops and else-
where. My present invention relates to an improvement in the manipulating
mechanism described in the said Specification, whereby I greatly simplify its
construction and facilitate its use. Instead of the keys formerly described by the
depression of one or other of which a toothed segment gave greater or less move-
ment to the counting gear, I now employ a set of levers which, according as their
arms are of greater or less length, move through a greater or less number of teeth
racks which work the counting gear. By a lock applied to the operating lever I
provide also means of preventing the machine from being tampered with, except
by the possessor of an appropriate key.

COMPLETE SPECIFICATION.
An Improvement in Counting and Registering Apparatus for Tills.
I, HENRY POTTIN, of No. 35 Rue Lepeletier Paris, France, Civil Engineer, 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:-
In the Specification No. 3313 of 1883 of a Patent granted to John Imray for
an invention communicated to him by me from abroad, is described apparatus
for counting and registering sums of money paid by customers in shops and
elsewhere.
as
My present invention relates to an improvement in the manipulating mechanism
of such apparatus, whereby I greatly simplify its construction and facilitate its use,
I shall describe referring to the accompanying drawing which shews part of
the manipulating mechanism corresponding with that which is shewn in Fig. 1 of
the drawings annexed to the previous Specification No. 3313 of 1883, but modified
according to my present invention.
Instead of the keys a, formerly described, by the depression of one or other of
which a toothed segment B gave greater or less movement through a pinion C to
the counting gear, I now employ a set of lever keys 1, 2, &c. to 9 having slotted
arms L L &c. increasing in length and somewhat varied in shape from the
uppermost one which is intended to count 1 to the lowest which is intended to
count 9.
The slots of these lever keys engage with pins alternately on opposite sides
of a sliding bar M having rack teeth engaging with pinions P and Q which work
counting and registering mechanism of the kind described in the previous
Specification.
Owing to the differences in the lengths and shapes of the lever keys L, each
of the pinions P, Q is moved a number of teeth increasing from 1 tooth moved
by the depression of lever key 1 to 9 teeth moved by the depression of lever
key 9.

page_text: The operating lever H corresponding in function with that marked L in Fig. 3 of
the drawings annexed to the previous Specification is made with a projecting arm 10
which enters a lock 11.
By locking the lever the machine is prevented from being tampered with except
by the possessor of a key suited to the lock 11.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a counting and registering apparatus for tills, of the kind described in the
Specification No. 3313 of 1883, in combination with the pinions driving the
counting and registering mechanism, a sliding bar rack geared to those pinions
and provided with pins acted on by lever keys which are of such lengths and
shapes that, by the depression of one or other of them, the sliding bar is so
far moved as to turn the pinions a number of teeth from 1 to 9, substantially as
described.
Dated this 30th day of December 1892.
