Improvements in Apparatus for Recording Time.
I, OTTO SCHULZE of Guben in the Kingdom of Prussia, German Empire, 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:-
The subject of the present invention is an apparatus, in combination with a clock,
for registering the duration of work-time by graphically noting the times of
commencement and leaving off of work by the persons to be controlled.
In the accompanying drawing the arrangement of the apparatus is shewn in
Fig. 1 by cross-section and in Fig. 2 by a view with the front-plate removed,
Fig. 3 shewing a plan of the graphical representation.
Between the two supporting walls a and b of a strongly made clock, mounted on
a broad trestle c, are inserted close to one another two type-discs d, e. The former
of these, the hour-disc d, has embossed at its periphery the ciphers from 0 to 24
inclusive, whilst the second, the minute disc, e, bears in similar manner those
ciphers between 0 and 60 exclusive, which are divisible by 5. By means of
suitably formed intermediate mechanism the rotation of these two discs by the
operating clock is effected in such a manner that the disc e is turned by a jerk
through the distance of one cipher after a lapse of 5 minutes, whilst the similar
movement of the disc d takes place after each complete rotation of the minute disc.
Under these two discs is situated a plate f, parallel to the axis of rotation p of the
discs. Onto this plate f the card strips or tickets 1, for registration of the time,
are to be introduced, through two slots i and k situated in the front wall h of the
trestle c, under the cipher-dial g of the operating clock. Should a card-strip be
pressed against the discs by means of a stamp m situated centrally underneath the
discs d, e, then the ciphers at the place of contact, expressing the time at the
moment shewn by the clock, are stamped in dry impression upon
surface
of the card-strip. The stamp m receives its upward movement by pressure applied
on the knob n and its return movement by means of the spring o.

upper
The two slots i and k are placed in such relation to each other that the imprints
upon the card-strip l, introduced to the same extent through either slot alternately
come under each other. Thus whilst the stamping on the part of the persons to be
controlled always comes on the middle line of the card-strip on their arrival, on
their departure it always takes place above the same. By simple subtraction of
the figures one is enabled to determine in hours and minutes the length of time
that person has been present at the place of work. The work-ticket can be so
arranged as to be applicable for several periods of labour. For this purpose it is
divided into fields by cross lines and each time it is used it is pushed the length of
one field further into the two slots.
The card at its top-end, lengthwise bears the denotations: Departure, Arrival,
Worktime.
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 control apparatus for registering work-time, consisting of two type-discs
having ciphers embossed upon their peripheries, a double slotted plate for recep-
tion of card-string a spring stamp for causing imprints of the disc-ciphers to be
.

for rotating the said discs by jerks, all substantially as and for the purpose herein-
before described and illustrated in the accompanying drawing.
