I WILLIAM CHADBURN of 11 Waterloo Road, Liverpool, in the County of
Lancaster, Optician do hereby declare the nature of the said Invention for
IMPROVEMENTS IN COUNTERS FOR INDICATING AND REGISTERING THE NUMBER
OF MOVEMENTS OF PARTS OF MACHINES to be as follows:-
A counter such as ordinarily used for indicating and registering the number of
revolutions of the crank shafts of steam and other engines with my improvements
applied thereto consists as follows. The numeral discs are mounted on a shaft in
the ordinary way, the units disc being provided with pins, or teeth upon which the
operating mechanism works. The arrangement and construction of the operating
mechanism which forms the chief features of my Invention is so combined with
relation to the numeral discs that any extra amount of movement of it, or the
reversing of it either by reciprocating, or revolving it in either direction will not
injuriously affect the proper working of the counter, or bring any undue strain
upon the apparatus, and it consists as follows: A shaft is mounted upon suitable
bearings. This shaft is carried through and out on both sides of the instrument
whereby it can be operated from either side, thus providing for a right, or left
hand reciprocating, or rotary action. On, or to this shaft is mounted the
mechanism for actuating the unit disc and so the other numeral discs above
mentioned. This mechanism is constructed in such a manner that only one
numeral on the unit disc is moved forward for each movenient of the shaft,
whatever the amount of such movement may be above the necessary amount to
move one numeral, also that by reversing the movement it does not affect the
numerating parts of the apparatus. A suitable mechanism for carrying out this
part of my Invention consists of a sliding, hinged, or rocking pawl, or tappet,
working in, or on a suitable bearing in connection with the shaft. This pawl, or
tappet is kept up to its work by a spring preferably of a long flat form.
A pawl
is provided to lock, or maintain the position of the numeral discs after the advance
of each unit.

I WILLIAM CHADBURN of 11 Waterloo Road, Liverpool in the County of
Lancaster, Optician do hereby declare the nature of the said Invention for
IMPROVEMENTS IN COUNTERS FOR INDICATING AND REGISTERING THE NUMBER
OF MOVEMENTS OF PARTS OF MACHINES and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement:-
A counter such as ordinarily used for indicating and registering the number of
revolutions of the crank shafts of steam and other engines with my improvements
applied thereto, consists as follows. The numeral discs are mounted on a shaft in
the ordinary way, the units disc being provided with pins, or teeth upon which the
operating mechanism works. The arrangement and construction of the operating
mechanism which forms the chief features of my Invention is so combined with
relation to the numeral discs that any extra amount of movement of it, or the
reversing of it either by reciprocating, or revolving it in either direction will not
injuriously affect the proper working of the counter, or bring any undue strain
upon the apparatus and it consists as follows: A shaft is mounted upon suitable
bearings. This shaft is carried through and out on both sides of the instrument
whereby it can be operated from either side, thus providing for a right, or left
hand reciprocating, or rotary action. On, or to this shaft is mounted the
mechanism for actuating the unit disc and so the other numeral discs above
mentioned. This mechanism is constructed in such a manner that only one
numeral on the unit disc is moved forward for each movement of the shaft
whatever the amount of such movement may be above the necessary amount
to move one numeral also by reversing the movement it does not affect the
numerating parts of the apparatus. A suitable mechanism for carrying out this
part of my Invention consists of a sliding hinged, or rocking pawl, or tappet
working in, or on a suitable bearing in connection with the shaft. This pawl, or
tappet is kept up to its work by a spring preferably of a long flat form. A pawl
is provided to lock, or maintain the position of the numeral discs after the advance
of each unit.
In order that my Invention may be more clearly understood, I will now proceed
to more particularly describe the same, reference being had to the annexed sheet of
Drawings, which makes part of this Specification, and to the letters and figures
of reference marked thereon. Like letters and figures being used to denote like
parts throughout the Drawings,

page_text: Figure 1 1s & plan, shown with the cover removed, of & counter provided with
the improvements according to this Invention.
Figure 2 is a front elevation of Figure 1.
Figure 3 is a sectional elevation through X X Figure 1 shown with the cover
in position.
Figure 4 is a plan of the counter with the cover in position.
Figure 5 is an end view of Figure 4.
The Drawings illustrate a known type of counter, used for indicating and
registering the number of revolutions of the crank shafts of steam and other
engines, with my improvements applied thereto.
The counter consists as follows. a are numeral discs which are mounted on a
shaft b carried by brackets c from a frame, or base d in the usual way.
The first,
or units disc is provided with pins, or teeth e upon which the operating mechanism
works. The arrangement and construction of the operating mechanism which
forms the chief feature of my Invention is so combined with relation to the
numeral discs a that any extra amount of movement of it, or the reversing of it
either by reciprocating, or revolving it, in either direction will not injuriously
affect the proper working of the counter, or bring any undue strain upon the
apparatus. This operating mechanism according to my Invention consists as
follows. A shaft is mounted on and carried by the bearing c: this shaft f is
carried through and projects out on both sides of the instrument whereby it can be
operated from either side by a lever such as g, thus providing for a right or
left hand reciprocating, or rotary action. On, or to this shaft f is mounted the
mechanism for actuating the unit disc and so the other numeral discs a above
mentioned. This actuating mechanism is constructed in such a manner that only
one numeral on the unit disc a is moved forward for each movement of the shaft f
whatever the amount of such movement may be above the necessary amount
to move one numeral; also by reversing the movement it does not affect the
numerating parts of the apparatus.
The mechanism for carrying out this part of my Invention and as illustrated by
the example shown in the Drawings consists of the pawl, or tappet h, which slides
between the cheeks i which are fixed on the shaft f by the sleeve and pin ¹. The
pawl h is provided with a shank ¹ which passes through the shaft f, the end of
the shank being provided with a head on which bears a long flat spring k which
keeps the pawl h up to its work against the pins, or teeth e of the unit disc a as
shown at Figure 3. A pawl is provided to lock, or maintain the position of the
numeral discs a after the advance of each unit by the reciprocating movement, or
the entire revolution of the pawl h. I would have it clearly. understood that the
pawl may have reciprocating movement given to it by moving the lever g
to the position shown in dotted lines in Figure 5, or it may have rotary move-
ment given to it by turning the lever completely round as shown by the dotted
circle. In both cases the action of the pawl h on the tooth of the unit wheel a
will be the same and it cannot strain the apparatus when moved in a reverse
direction.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
