Improvements in Apparatus for Indicating, Registering, Numbering,
or Counting.
1, CHARLES HENRY DAVIDS of 61 Patchen Avenue, Brooklyn in the County of
Kings and State of New York, United States of America, Mechanical Engineer, do
hereby declare the nature of this invention to be as follows:-
My improvements in apparatus for automatically indicating, registering, numbering,
or counting persons, weights, measures, movements, periods of time, etc.; such as are
commonly known as "registers" and "numbering machines," relate more particularly
to that class of such apparatus in which the numbers or letters used for indicators are
placed on the peripheries of concentric wheels. In mechanism of this class, as hitherto
constructed one or both of two objectionable features are found, viz. :-either a certain
amount of space between the number wheels is used to admit and contain certain parts
of the operating mechanism, thus separating the number wheels and the figures carried
by them, to a greater extent than is desirable or would otherwise be required; or if
the mechanism is of such a nature as to admit the close juxtaposition of the number
wheels, the use of springs and other unreliable and non-positive devices was deemed
necessary.
My Invention consists of simple trains of positive mechanism, so arranged as to be
wholly contained within the peripheries of the number wheels, thus allowing a close
juxtaposition of said wheels and assuring a positive certainty of their movements.
Upon a grooved stud rotate, (by preference intermittently) several number wheels, one
for each figure in the highest number which the device may be required to register or
record. Secured upon the grooved stud are two collars which serve as supports for a
spindle on which rotate pinions provided with stops secured thereto in such manner as
to practically form parts thereof. The pinions mesh with internal gear wheel segments,
and with internal gear wheels, each segment being secured upon one side of the web
of a number wheel and each internal gear wheel being secured upon the opposite side
of one of said webs, except as hereinafter mentioned respecting the first and last
-

page_text: wheels of each series. In the web of each number wheel except the last in each series,
is formed a recess which admits in turn each arm of a stop which is formed with
several sides, preferably three in number, each stop being placed preferably directly
within the circumference of the web of a number wheel. The first wheel in each series
requires no gear wheel, and the last wheel in each series needs no recess in its web,
and requires no stop, nor segment.
The operation of the apparatus considered as adapted to decimal numbers, each
wheel carrying the figures from "0" to "9" inclusive, is as follows, viz. the first
or unit wheel being rotated by suitable mechanism, presents at the point of inspection
or impression, the several figures named until the figure "9" has been shown or
impressed, when further rotation of the unit wheel causes the segment attached thereto,
to engage with and partially rotate a pinion and by means of the latter and an internal
gear wheel to partially rotate the next number wheel which may be called the decimal
wheel, a sufficient distance to bring the next succeeding number or figure to the point
of inspection or impression as the case may be, while during such partial rotation of
the decimal wheel, the recess in the web of the unit wheel admits and receives the arm
or radially largest part of the stop. This motion of the decimal wheel having been
finished, it comes to rest and cannot again be rotated until the recess in the web
of the unit wheel is again in position to admit an arm of the stop. Any number
of wheels may be operated as described, each by the next preceding wheel.
A spur pinion or other device may be attached to the spindle which carries the
pinions and stops above mentioned, to be used for the purpose of communicating with
an alarm bell or other signal, when a certain number has been counted by the apparatus.
In such a case, the spindle must be caused to revolve by being connected with one of
the pinions.

Improvements in Apparatus for Indicating, Registering, Numbering,
or Counting.
I CHARLES HENRY DAVIDS, of 61 Patchen Avenue, Brooklyn in the County of
Kings and State of New York, United States of America, Mechanical Engineer 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 improvements in apparatus for automatically indicating, registering, numbering
or counting, persons, weights, measures, movements, periods of time, &c., such as are
commonly known as and designated "registers" and "numbering machines," relate
more particularly, to that class of such apparatus, in which the numbers or letters
used for indicators, are placed on the peripheries of concentric wheels.
In mechanism of this class, as hitherto constructed, one or both of two objectionable
features are found, viz.: either a certain amount of space between the number wheels
is used to admit and contain certain parts of the operating mechanism, thus separating
the number wheels and the figures carried by them, to a greater extent than is desirablo
or would otherwise be required; or, if the mechanism is of such a nature as to admit
the close juxtaposition of the number wheels, the use of springs and other unreliable
and non-positive devices was deemed necessary.
My invention consists of simple trains of positive mechanism, so arranged as to be
wholly contained within the peripheries of the number wheels, thus allowing
close juxtaposition of said wheels and assuring a positive certainty of their
movements.

In the drawing, Figure 1 is a longitudiual section through the centre of the device,
at the line, figures 2, 4 and 5, each part, except the spindle C, being shown in
section through its centre; Figure 2 is an end elevation of the device; Fig. 3. is a
side elevation of a stop 3, and a portion of a number wheel 6, both being shown in
their relative positions when the stop 3 is at rest; fig. 4 is a side elevation of a number
wheel 6, an internal gear wheel segment 4, and a stop 3; the latter being in position
as of a half-completed movement; fig. 5 is a side elevation of a number wheel 6, the
spindle C, a pinion 2, and a section of the grooved stud A, through the line z z, figs. 1
and 13 fig. 6 is a side elevation and fig. 7 is a front elevation of a pinion 2; fig. 8
is a side elevation and fig. 9 is a front elevation of stop 3; fig. 10 is a front elevation
of an internal gear wheel segment 4; fig. 11 is a front elevation and fig. 13 is a side
elevation of a form of the stop 3 preferable for use in connection with wheels having
ten digits or numbers; fig. 13 is a side elevation and fig. 14 an end elevation of the
grooved stud A.

page_text: Upon a grooved stud A, rotate, by preference intermittently, several number
wheels 6, 6, 6, 6, 6, 6, one for each figure in the highest number which the dovice may
be required to register or record. Secured upon the grooved stud A, are two
collars B, B, which serve as supports for a spindle C, on which rotate the pinions 2, 2,
2, 2, 2, and stops 3, 3, 3, 3, 3, each of the latter being so secured to a pinion that it
practically formis a part thereof. The pinions 2, 2, mesh with internal gear wheel
segments 4, 4, 4, 4, 4, and with internal gear wheels 5, 5, 5, 5, 5, each segment 4,
being secured upon one side of the web 7, of a number wheel 6, each gear wheel 5,
being secured upon the opposite side of one of said webs, except as hereinafter
mentioned respecting the first and last wheels of each series. In the web 7, of each.
number wheel 6, except the last in each series, formed a recess 8, which admits, in
turn, each arin of a stop 3, which is formed with several sides, preferably three in
number, and is, in shape, substantially as shown in the drawing. Each stop 3,
is placed, preferably, directly within the circumference of the web 7; of a number
wheel 6.
The first wheel in each series requires no gear wheel, and the last wheel in
each series needs no recess in its web, and requires no stop 3, nor segment 4.
The operation of the apparatus, considered as adapted to decimal numbers, each
wheel carrying the figures from "0" to "9" inclusive, is as follows, viz.: the first, or
unit wheel being rotated by suitable mechanism, presents at the point of inspection or
impression, the several figures named until the figure "9" has been shown or
impressed, when further rotation of the unit wheel causes the segment 4, attached
thereto, to engage with and partially rotate the pinion 2, and, by means of the latter
and a gear wheel 5, to partially rotate the next number wheel 6, which may be called
the decimal wheel, a sufficient distance to bring the next succeeding number or figure
to the point of inspection or impression, as the case may be, while, during such partial
rotation of the decimal wheel 6, the recess 8, in the web 7 of the unit wheel 6, admits
and receives the arm or radially largest part of the stop 3. This motion of the decimal
wheel 6, having been finished, it comes to rest and cannot again be rotated until the
recess 8, in the web 7 of the unit wheel 6, is again in position to admit an arm of the
stop 3. Any number of wheels may be operated as described, each by the next
preceding wheel.
A spur pinion 1, or other device may be attached to the spindle C, to be used for
the purpose of communicating with an alarm bell or other signal (not shown in the
drawing) when a certain number has been counted by the apparatus. In such a case
the spindle C, must be caused to revolve by- being connected with one of the
pinions 2.
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. A polygonal, rotating stop, in combination with a rotating indicator wheel having
an internal circular face in its web, said face having a recess so arranged that at each
rotation of said wheel the several angles of said stop consecutively engage said recess;
permitting partial rotation of said stop and consequent operation of mechanism con-
nected therewith, all combined with mechanism operating said stop, substantially as
herein shown and described.
2. An indicator wheel, carrying a toothed internal gear segment which intermittently
meshes with and operates a spur pinion, the latter meshing with and operating an
internal gear wheel attached to and pivoted with a second indicator wheel, both of said
indicator wheels being pivoted concentrically; all combined substantially as herein
shown and described.
3. An indicator wheel, carrying a toothed internal gear segment which intermittently
meshes with and operates a spur pinion which is attached to and pivoted with a poly-
gonal, rotating stop, the several sides of which consecutively engage with an internal

page_text: circular face in a rotating indicator wheel, said face having a recess so arranged that
at each rotation of said wheel, said recess admits an angle of said stop synchronously
with the operation of said spur pinion, all, combined with each other and with
mechanism operated by said spur pinion, substantially as herein shown and
described.
