An Improved Counting Apparatus for Bodies with Rotary
Movement.
I, FRIEDRICH WILHELM GUSTAV BRUHN, of 1 Schaper Strasse, Berlin W.
in the Empire of Germany, Manager, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved counting apparatus 'for' bodies' with rotary
movement.
This improved apparatus comprises a clock work, upon the rotary axis of which
a disc is keyed which is revolved once in about 24 hours. The disc is adapted to
carry upon two small pins a larger dial plate provided with divisions for indicating
the time; this dial plate is secured against falling off the disc by a spring :arm
which is rotatably attached to a covering-plate and which exerts a pressure upon
the dial plate by means of a ring fixed on said spring.
Independent of two exterior cog wheels forming part of the clock work an axis
carrying a toothed ratchet wheel is arranged upon the case plate, which axis
moreover carries a worm and an eccentric. A spring presses one extremity of an
oscillating lever, arranged on a fixed pivot, against the eccentric; the other
tapering extremity of this lever, is located according to the position of the
eccentric either opposite a pressing pin or it slides underneath this latter along the
same. The said pressing pin which is displaceably arranged below the edge of
the dial plate, has an upper point and is held in position below the dial plate by
means of a spring so long as the oscillating lever aforesaid lies by the side of the
said pin. On the clock work casing a small plate is fixed, which slightly projects
over the edge of the dial plate.
With the teeth of the beforementioned ratchet wheel a push pawl engages
which is suspended from a weighted lever which latter is enabled to oscillate
around a fixed pivot within a limit given by a guide. Further a stop pawl engages
with the said ratchet wheel.
The before described apparatus is adapted to be passed around inside a casing
by the rotary body to be controlled and to thus cause the pressing pin to enter
from below the dial plate rotated by the clock work, this entering movement being
effected by the weighted oscillating lever in connection with the ratchet wheel,
the eccentric and the first mentioned oscillating lever. The impressions
produced by the pressing pin in the dial, apart from the existing marks thereon,
are signs which indicate the various conditions or proportions of the rotary
movements.
The pressing pin or device is carried by a pin which latter is surrounded by
a slot provided in the pressing pin or device. The pressing pin or device bears
outwardly against another pin, which latter prevents the pressing pin or device
from giving way laterally when the oscillating lever is caused to slide along
beneath the pressing pin and to force the latter against the dial. On the other
hand the pressing piu or device is enabled to give way to the oscillating lever
when sliding back toward the other direction and thus not to enter the dial
plate.
The arrangement is adapted to receive a mechanism capable of indicating the
distance travelled by a revolving point of the rotary body. The beforementioned

page_text: worm arranged on the axis of the ratchet wheel engages with a worm wheel the
driving pinion of which engages with a crown wheel. This latter is provided with
graduations for indicating the distance travelled and can be thrown out of gear
with the said driving pinion by pushing it back upon its axis against a spring for
the purpose of adjusting it while in this position, to the zero point.

An Improved Counting Apparatus for Bodies with Rotary
Movement.
I, FRIEDRICH WILHELM GUSTAV BRUHN, of 1 Schaper Strasse Berlin W..
in the Empire of Germany, Manager, 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 an improved counting apparatus for bodies with rotary
movement; and it consists in certain novel features of construction and
combinations of parts, as will be hereinafter fully described.
In order that my invention may be more fully understood I have illustrated the
same in the accompanying drawing in which
Figure 1 is a front view of the interior of the counting apparatus; the covering
plate being removed for the sake of clearness.
Figure 2 is a vertical section of the apparatus on the line 2-2 (Figure 1);
Figure 3 is front view of the dial plate of the apparatus; and
Figures 4 and 5 are views showing details of construction.
Similar letters refer to similar parts throughout the several views.
The improved apparatus comprises a clock work which for the sake of simplicity
is not shown on the drawing except two toothed or cog wheels a' and a². Upon
the rotary axis a of this clock work is keyed a disc b which is revolved once in
about 24 hours. The disc is adapted to carry upon two small pins 6₁ a larger
dial plate e provided with divisions for indicating the time; this dial plate c is
secured against falling off the disc 6 by a spring arm d which is rotatably attached
to a covering-plate B and which exerts a pressure upon the dial plate c by means
of a ring d¹ fixed on the said spring arm Figure 2.
Independent of the exterior cog wheels a¹ a² forming part of the clock work an
axis e carrying a toothed ratchet wheel e is arranged upon the case plate A, which
axis moreover carries a worm f and a cam g. A spring presses one extremity
of an oscillating lever h, arranged on a fixed pivot h² against the cam g; the other
tapering extremity of this lever h, is located according to the position of the
eccentric either opposite a pricker i or it slides underneath this latter along the
same. The said pricker i which is displacably arranged below the edge of
the dial plate c, has an upper point and is held in position below the dial plate by
means of a spring so long as the oscillating lever lies by the side of the said
pin i. On the clock work casing or covering plate B respectively a small plate d
is fixed, which slightly projects over the edge of the dial plate c (Figures 3
and 4).
With the teeth of the beforementioned ratchet wheel e a push pawl k engages
which is suspended from a weighted lever 13 which latter is enabled to oscillate
around a fixed pivot within a limit determined by a guide 12.
Further a stop
pawl m engages with the ratchet wheel e.
The before described apparatus is adapted to be rotated inside a casing by the
rotary body to be controlled and to thus cause the pricker i to pierce from below

page_text: through a suitable slot p' (Figures 3 and 4) of the covering plate B into the dial.
plate c rotated by the clock work, this pricking movement being effected by the
weighted oscillating lever 1 in connection with the ratchet wheel e,. the
eccentric g and the first mentioned oscillating lever h. The impressions produced.
by the pressing pin in the dial e apart from the existing inarks thereon are
signs which indicate the various conditions or proportions of the rotary
movements.
The pricker or device is carried by a piu 3 which latter lies in a slot i
provided in the pricker or device . The pricker or device bears outwardly
against another pin 2, which latter prevents the pricker or device i from giving
way laterally when the oscillating lever his caused to slide along beneath the
pressing pin and to force the latter against the dial c. On the other hand
the pricker or device i is enabled to give way to the oscillating lever 'when.
sliding back toward the other direction and thus not to pass through the dial.
plate c.
The beforementioned worm farranged on the axis e of the ratchet wheel e
engages with a worm wheel n the driving pinion n' of which engages with a crown
wheel o.
This latter is provided on its circumferential surface with graduations
for indicating the distance travelled and can be thrown out of gear with the said
driving pinion n' by pushing it back upon its axis o2 against a spring o' for the
purpose of adjusting it while in this position, to the zero point. For observing the
indicating wheel a a suitable slot or sight hole p may be provided in the covering
plate B (Figures 2 and 3).
As many changes might be made in the construction and relative arrangement
of the different parts without involving a departure from the spirit of my
invention, I would have it understood that I do not limit myself to the exact
construction shown and described and forming only an example, and that I may
make such changes and alterations as may be deemed expedient within the scope
of my invention.
Having now particularly described and ascertained the nature of any said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A counting apparatus for bodies with rotary movement adapted to be rotated
by such rotary body and mainly consisting of a dial plate revolved by a clock
work, and of a pricker, which latter in connection with a lever and ratchet device
is adapted to impress marks or signs in the graduated dial plate, substantially as
and for the purpose set forth.
2. In a counting apparatus as herein described the combination of a lever- and
ratchet device, consisting of an oscillating weighted lever 1, a ratchet wheel e,.
a cam g and an oscillating lever h, these parts being adapted to press a pricking.
device i against a clock-work actuated dial plate, substantially as and for the
purpose specified.
3. In a counting apparatus as hereindescribed the combination of the lever-
and ratchet device with a contrivance for measuring the distance travelled by the
rotary body, consisting of a worm and worm wheel co-operating with the said lever-
and ratchet device and designed to actuate suitable means for indicating the
distance travelled, substantially as and for the purpose specified.
