Improvements in and relating to Indicating and Registering
Apparatus.
I, FRIEDRICH WILHELM GUSTAV Bruhn, of Berlin, W.1 Schaperstrasse,
in the Empire of Germany, Director do hereby declare the nature of this invention
to be as follows:-
My invention relates to indicating and registering apparatus.
Indicating and registering apparatus have generally for their object to
continuously record successive events of the same kind, the indicating mechanism
recording each single event by itself, and the registering mechanism the total of all
the events. On the termination of each event the attendant or person watching
the apparatus has to put the indicating mechanism back to its original position and
to stop the movement of the registering mechanism.
In many cases however particular events take place between successive similar
events, the occurrence and kind of which it is very desirable to characterize specially
by themselves. To mention as an example a definite case, public chairs to be let by
the time are provided with indicating and registering apparatus. When a chair is
occupied its apparatus will be automatically set in motion and must, after the chair
has been used, be thrown out of action again by an authorized attendant. The user
and attendant read off on the indicating apparatus the price to be paid to the
attendant, while the registering apparatus records the total of the several payments
made to the attendant by a number of users, thus enabling the proprietor of the
chair to ascertain his total receipts.
If now the user of a chair desires a particular service to be rendered by the
attendant, for instance the supply of a refreshment, it is very desirable, as before
stated, in order to control the receipts which the attendant has to hand over in
respect of these particular services, that the price of each service shall be rendered
visible to the user of the chair and that the total of all these special receipts shall
also be registered for the proprietor of the chair.
It would be difficult to effect indications of this kind automatically on account.
of the variety of the services required, and it is therefore expedient to have such
indications effected on an accessory recording device by the attendant or person
rendering the service, who for instance moves the pointer of a mechanism by hand
to a definite position, which indication stating the price paid for the service is then
added by the registering mechanism to the indications previously recorded.
On the other hand it is by no means advisable to rely on the attendant for
moving back the pointer of this accessory mechanism which gives the several
indications to zero after each service or a number of services rendered to the same
user of a chair, because the attendant bas no interest in this, but on the contrary
might unlawfully realize for himself a profit at the expense of his employer, if he
left the pointer in a recording position, and took from a subsequent user an amount
corresponding to this recording position without such amount being added by the
registering mechanism of the accessory apparatus to the other amounts.
The perception of this fact has led to the idea underlying my said invention, of
rendering the return movement of the pointer of an accessory apparatus for special
or exceptional services or events dependent upon the other principal apparatus for
indicating and registering successive events of the same kind (use of chairs) being..

page_text: thrown out of action, because the attendant is absolutely interested in the fulfilment
of the duty of throwing the latter apparatus out of gear, inasmuch as the registering
mechanism of the principal apparatus which consecutively adds the single events
(single occupations of chairs) will remain in action and record also the intervals
between the single events as paid for, if it has not been stopped after each event
(use of chair). By such a relation of the accessory apparatus for recording
unusual events to a principal apparatus, which registers automatically and has to
be thrown out of gear, for events of the same kind, existing conditions are utilized
in the most practical manner, and the arrangement of the accessory mechanism is
well considered.
It will be understood that the arrangement and the combination of the accessory
apparatus for recording special events with the principal apparatus for consecutive
events may be greatly varied. I will proceed to describe a constructional form of
the same which has been found very practical.
Above a recording disc, for instance the dial, the pointer of an accessory
mechanism may be moved by steps from one dial indication to the other, if
somebody, that is to say an attendant, presses upon a knob outside. This knob
then moves a stamp or slide supported in the casing of the apparatus and provided
with two pawls. Each of these pawls engages with a toothed wheel, and turns its
wheel one tooth when the knob displaces the slide. On the axis of one of these
toothed wheels is the dial pointer which is therefore moved by steps, while the
:second toothed wheel appertains to a wheel-work which in the known manner adds
the several events indicated by the pointer, for instance services in the shape of
amounts of money to be paid and indicated by numbers on the dial plate in units,
tens, hundreds etc., and which renders them visible through sight holes in the dial
plate.
After each operation the aforesaid knob is returned to its original position by a
spring and the slide by another spring, while the two toothed wheels are held in
their positions by pawls.
On the termination of a special event recorded by the registering mechanism,
for example the payment for one or more refreshments handed to the same person
in accordance with the position in which the pointer is placed by the attendant, the
pointer has to be put back to zero for the reasons herein before stated as soon as, to.
take the above example again, the user of a chair leaves the same so that it may be
occupied by another person, or speaking generally, as soon as the ordinary event,
commencing prior to or with the special event and recorded by the principal
indicating and registering apparatus, is at an end and another event of the same
kind is again expected. This return movement of the pointer takes place by means
of the principal indicating mechanism which the attendant throws out of action in
his own interest when the chair is given up and when the ordinary event has
therefore terminated and its repetition is expected. By throwing the principal
mechanism out of gear a presser is forced against one of the pawls, and lifts the
latter from the teeth of the corresponding wheel and this pawl, when it has not
already been drawn back far enough by the returning slide, will in turn disengage
the other pawl from the teeth of the said wheel so that the wheel and with it the
pointer are turned back to their original position by a spring, while the said
registering mechanism remains in its position and passes back to zero again in the
.well-known manner only after the termination of a certain number of revolutions.
With the before-described indicating mechanism may be combined a special
ratchet device to prevent the registering mechanism being moved on by pressing
upon the knob, if the pointer has reached its terminal position and the toothed
wheel cannot then be turned any further. In this case the pawl has engaged with
a last tooth of this wheel which is deeper than the other teeth of the wheel and
therefore enables the pawl to enter deeper into the space in front.
In consequence
of this arrangement the slide by means of a nose takes behind a stop pin provided
on an oscillating lever and kept pressed by a spring of this lever against the said
pawl. While the other shallow teeth of the wheel are used the stop pin canot

page_text: come within reach of the nose on the slide, and the slide and knob are pressed
upwards again by their springs. When however the pawl enters the deepened
tooth of the wheel it permits the stop pin to fall over the nose, because it moves
somewhat more to one side and the oscillating lever will follow this turning move-
ment of the pawl. A continued operation of the slide by the knob is therefore.
impossible for the present, consequently the registering mechanism cannot be moved.
further by the corresponding pawl as long as the pointer occupies its terminal
position. When however the principal mechanism is thrown out of action the
oscillating lever with its pin is lifted from the nose by the before-mentioned pawl.
which as stated is moved every time the principal mechanism is thrown out of gear
by the pawl actuated by the presser. The slide is pulled upwards again by its
spring and the pointer darts back to zero at the same time.

Improvements in and relating to Indicating and Registering
Apparatus.
I, FRIEDRICH WILHELM GUSTAV BRUHN, of Berlin W. 1 Shaperstrasse, in
the Empire of Germany, Director 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 improvements in and relating to indicating and
registering apparatus.
Indicating and registering apparatus have generally for their object to con-
tinuously record successive events of the same kind, the indicating mechanism
recording each single event by itself, and the registering mechanism the total of
all the events. On the termination of each event the attendant or person watching
the apparatus has to return the indicating mechanism to its original position and
to stop the movement of the registering mechanism.
In many cases however particular events take place between successive similar
events, the occurrence and kind of which it is very desirable to characterize
specially by themselves. To mention as an example a definite case, public chairs
to be let by the time are provided with indicating and registering apparatus.
When such a chair is occupied its apparatus will be automatically set in motion
and, after the chair has been used, must be thrown out of action again by an
authorized attendant. The user and attendant read off on the indicating apparatus
the price to be paid to the said attendant, while the registering apparatus records
the total of the several payments made to the attendant by a number of users, thus
enabling the proprietor of the chair to ascertain his total receipts.
If now the user of a chair desires a particular service to be rendered by the
attendant, for instance the supply of a refreshment, it is very desirable, as before
stated, in order to control the receipts which the attendant has to hand over in
respect of these particular services, that the price of each service shall be rendered
visible to the user of the chair and that the total of all these special receipts shall
also be registered for the proprietor of the chair.
It would be difficult to effect indications of this kind automatically on account of
the variety of the. services required, and it is therefore expedient to have such
indications effected on an accessory recording device by the attendant or person:
rendering the service, who for instance moves the pointer of a mechanism by hand

page_text: to a definite position, which indication stating the price paid for the service is then
added by the registering mechanism to the indications previously recorded.
On the other hand it is by no means advisable to rely on the attendant for
moving back to zero the pointer of this accessory mechanism, which gives the
several indications, after each service or a number of services rendered to the same
user of a chair, because the attendant has no interest in this, but, on the contrary
might unlawfully realize for himself a profit at the expense of his employer, if he
left the pointer in a recording position and took from a subsequent user an amount
corresponding to this recording position without such amount being added by the
registering mechanism of the accessory apparatus to the other amounts.
The perception of this fact has led to the idea underlying my said invention, of
rendering the return movement of the pointer of an accessory apparatus for special
or exceptional services or events dependent upon the throwing out of action of the
other principal apparatus for indicating and registering successive events of the
same kind (such as the use of chairs), because the attendant is absolutely interested
in the fulfilment of the duty of throwing the latter apparatus out of gear, inasmuch
as the registering mechanism of the principal apparatus which consecutively adds
the single events (for example the single occupations of chairs) will remain in
action and record also the intervals between the single events as paid for, if it has
not been stopped after each event. By such a relation of the accessory apparatus
for recording unusual events with a principal apparatus which registers auto-
matically and has to be thrown out of gear, for events of the same kind, existing
conditions are utilized in the most practical manner, and the arrangement of the
accessory mechanism is well considered.
It will be understood that the arrangement and the combination of the accessory
apparatus for recording special events with the principal apparatus for consecutive
events may be greatly varied. I will proceed to describe a constructional form of
the same which has been found very practical; reference being made to the
accompanying drawing, forming part of this Specification, in which,
Figures 1, 2 and 3 are respectively, rear, side and front elevations of the
accessory recording device, and
Figures 4 and 5 are views illustrating the operation of the accessory recording
device.
Above a recording disc, for instance a dial a, the pointer 6 of an accessory
mechanism may be moved step by step from one dial indication to the other, if
somebody, that is to say an attendant presses upon a knob c outside, either directly
or by means of a handle 2 which pressure causes the said knob to move a stamp
or slide d supported in the casing of the apparatus and provided with two pawls e
and f. The pawls e and f engage with toothed wheels e¹ and f¹ respectively, and
each pawl turns its wheel one tooth forward when the knob c displaces the slide d.
On the axis of the toothed wheel e¹ is carried the dial pointer b which is therefore
moved step by step, while the second toothed wheel actuates a train of
wheels ff which adds the several events indicated by the pointer in the well
known manner, for instance services in the shape of amounts of money to be paid
and indicated by numbers on the dial plate in units, tens, hundreds and so on,
and which renders them visible through sight holes a¹ a¹ a' (Figure 3) in the dial
plate a.
After each operation the aforesaid knob c is returned to its original position by
a spring and the slide d is returned by another spring d¹, while the two toothed
wheels e' andare held in their positions by pawls g and h respectively.
On the termination of a special event recorded by the registering mechanism f*f"
ff, for example the payment for one or more refreshments handed to the same
person in accordance with the position in which the pointer is placed by the
attendant, the pointer 6 has to be put back to zero for the reasons hereinbefore
stated, as soon as, (to take the above example again,) the user of a chair leaves the
same so that it may be occupied by another person, or speaking generally, as soon
as the ordinary event, commencing prior to or with the special event and recorded

page_text: by the principal indicating and registering apparatus, is at an end and another
event of the same kind is again expected. This return movement of the pointer
takes place by means of the principal indicating mechanism which the attendant
throws out of action in his own interest when the chair is given up and when the
ordinary event has therefore terminated and its repetition is expected. By throwing
the principal mechanism out of gear a presser i is forced against the pawl gand
lifts the latter out of engagement with the teeth of the corresponding wheel el,
and this pawl, when it has not already been drawn back far enough by the
returning slide d, will in turn disengage the other pawl e from the teeth of the
wheel e so that this wheel and with it the pointer b'are turned back to their
original position, as shown in Figure 5, by a torsional spring k, (Figure 2) while
the registering mechanism f* fƒƒ³ remains in its position, and only passes back
to zero again, in the well-known manner, only after the termination of a certain
number of revolutions.
With the hereinbefore described indicating mechanism there may be combined
a special ratchet device to prevent the registering mechanism f* ƒ ƒ ƒ³ being moved
on when pressure is exerted upon the knob c, if the pointer b. has already reached
its terminal position (marked 19 on the dial a Figure 3), and the toothed wheel e
cannot then be turned any further. In this case the pawle has engaged with the
last tooth e² of the wheel el which is deeper than the other teeth of the wheel and
therefore enables the pawl e to enter deeper into the space in front. In consequence
of this arrangement the slide d by means of a projection or shoulder d catches
behind a stop pin / provided on an oscillating lever which is kept pressed against
the pawl e by a spring 2 (Figure 1). When the pawl e is in engagement with the
other teeth of the wheel e the stop I cannot come within reach of the shoulder d²
on the slide d, and the slide d and knob c are pressed upwards again by their
respective springs. When however the pawl e enters the deepened tooth e of the
wheel e¹ it permits the stop pin / to fall over the projection or shoulder d², because
it moves somewhat more to one side and the oscillating lever will follow this
turning movement of the pawle (Figure 4). A continued or further operation of
the slide d by means of the knob c is therefore impossible for the present, con-
sequently the registering mechanism f* f1f2 ƒ³ cannot be moved further by the
corresponding pawl as long as the pointer b occupies its terminal position. When
however the principal mechanism is thrown out of action the oscillating lever l
with its pin is lifted from the shoulder d by the pawl e (Figure 5) which, as
hereinbefore described, is moved every time the principal mechanism is thrown out
of gear by the pawl g actuated by the presser or sliding rod . The slide dis
pulled upwards again by its spring and simultaneously the pointer suddenly
returns to its zero position.
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. The combination of an accessory recording device for recording particular
events, with a principal apparatus contemporarily registering successive similar
events, in such a mauner, that on throwing the said principal apparatus out of
action the accessory recording device is automatically turned back into its original
or zero position, substantially as set forth.
2. In an accessory recording device subordinate, as hereinbefore described, to
a principal indicating and registering apparatus, the combination of the spring
actuated knob c and slide d with a pawi e adapted to operate a toothed wheel el
fixed on the shaft which carries the pointer, having a deepened tooth e² and
a pawl for operating a suitable registering mechanism f* f ƒ ƒ³, and two
ratchet pawls g and h, substantially as, and for the purpose specified.
3. In an accessory recording device subordinate, as hereinbefore described, to
a principal indicating or registering apparatus, the combination of a spring
actuated knob cand slide d baving pawls e and f, with a toothed wheel e¹ provided.

page_text: with a deepened tooth e³, a registering mechanism f* f¹ƒ ƒ³, ratchet-pawls gh,
a spring actuated lever provided with a stop pin adapted to engage a shoulder d²
on the slide d in order to lock the latter when the pawl e enters the said deepened
tooth of the wheel e¹, substantially as set forth.
4. In an accessory recording device subordinate, as hereinbefore described, to
a principal indicating or registering apparatus the means for unlocking the slide d
and for bringing back the said accessory recording device into its zero position,
consisting of a pressor or sliding rod i forming a part of or being actuated by the
principal apparatus, in combination with the ratchet-pawl g, the pawl e and the
lever and stop pin l, substantially as, and for the purpose set forth.
