COMPLETE SPECIFICATION.
Improvements in Indicating or Counting Apparatus.
We, ERNST PAPROTH, and ROBERT ASTER both of Kyritz-in-Priegnitz in the-
Empire of Germany, do hereby declare the nature of this invention and in what
manner the same to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has for its object an indicating or counting apparatus.
In order that the invention may be the more easily understood, reference will be-
made to the accompanying sheet of drawings, in which :-
Figures 1 and 2 are front and side views respectively of the apparatus.
Figure 3 is a front view of the same with face removed.
Figure 4 is the key of the apparatus, in plan and elevation.
Figure 5 is a side view of the apparatus partly in section.
Figure 7 is the spiral spring.
Figures 6, 8 and 9 are detailed views of the ratchet mechanism.
A spiral spring is arranged inside a case g, Figures 5 and 7, on the bottom of
the box, which spring is attached at one end to m or b, and, at the other end, to
a spindle s passing straight through the box b, Figure 7. A ratchet wheel fis
arranged on this spindle above the case g, Figures 3 and 5 and above the dial a
pointer a, Figure 1, which rests with one side against the stop pin h. A lever c is
arranged above the case y or the ratchet wheel f, Figure 6, so as to oscillate on a
fixed point p, and its outer end projects through the slot e, Figure 2, in the side of
the box b. The pivot p of the lever c serves, at the same time, as pivot for a
pallet o, Figure 6, which is pressed against the ratchet wheel ƒ by means of a
spring 3. The lever c has a pallet k hinged at y, which is also pressed against the
ratchet wheel by means of a spring 2. A spring 1 presses the lever c downwards.
If this indicator is to be set in action, the lever c, Figure 9, is moved upwards to.
the extent of one tooth of the wheel f, after which the lever c automatically
again returns to its former position, Figure 6. By this or subsequent movements
of the wheel, the pointer a is moved away from the pin 4, Figure 1, and stands
over the number desired. The spiral spring r is at the same time wound up in the
case g, Figure 7. If it is desired to set the pointer back again, a loose key i,.
Figure 4, is inserted in the neck or keyhole l, Figures 1, 5 and 6, and between the
points of the two levers o.k, Figure 8, by which means first the lever o and then
the lever are lifted out of the teeth, so that the ratchet wheel f is released, and
the spiral spring r automatically causes the spindle s, the ratchet wheel and
pointer a to return to their normal position, so that the pointer stands again at o,
that is, rests close against the stop pin h.
Having now particularly described and ascertained the nature of our said inven--
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvements in indicating or counting apparatus, which consist in a
lever c projecting from a box b and having, on a common pivot p, a pallet o, and,
at a second point y, another pallet k, so arranged as to engage in a ratchet wheel f
fixed on a spindles and actuated by means of a spring r situated between them,
also a pointer a arranged on the same common spindle s with the said ratchet
wheel, the pallets ok being capable of being disengaged from the teeth of the
ratchet wheel by means of an inserted key i, all substantially as described.
2. The general combined arrangement and construction of parts forming the -

page_text: improved indicating or counting apparatus substantially as hereinbefore set forth
and shown.'
