page_text: I, GEORGES LAFOND, of 34, Faubourg St. Martin, Paris, in the French Republic,
Engineer, do hereby declare the nature of this invention to be as follows:-
"
-
This invention relates to mechanical counters or adding-apparatus, some-
times known as totalisers" and "cash registers." It has for object to cause
these counters or registers to totalise the numbers of one or more units and
their sub-divisions.
The improvements comprise certain particular mechanical arrangements, and
the general working of these arrangements, in such a manner that they are
embodied in a concise form and that their manipulation is easy.
Mechanical counters according to my invention can be based on the decimal
or duodecimal system, or any other system of numeration, applied to a monetary
or other system. By way of example, I have shewn upon the accompanying
drawings:
.
1º. A model based on the duodecimal system in the shape of a watch although
this counter can be made in any other shape.
20. A model based on the decimal system for any sort of totalisation.
30. A model based on the French monetary system.
On the first drawing, Sheet 1, Figure 1 is a front view of this counter.
Figure 2 is a cross section made on line 2-2 of Figures 1 and 4.
Figure 3 is an elevation, in which the casing and the fixed dial-plates of the
counter are supposed to be removed so that only the movable dials can be seen.
Figure 4 is a third elevation, in which the upper plate serving as a support
to the movable dials is removed, so as to show the interior mechanism with all
the wheelwork or movements therein contained, the said mechanism being held
in a special cage which is located in one piece with the case or casing of the
counter.
Figures 5 and 6 are respectively a cross-section, and a plan view, of the cage
supporting the mechanism of the counter.
Figures 7 and 8 are respectively a cross-section and a plan view of a support
on which the various movements or sets of wheelwork are arranged to operate.
Figures 9 to 17 inclusive shew, in section and in plan, the various components
of one of these movements or sets of wheelwork.
Figure 18, shews in section and in plan, a device special to certain of these
movements.
Figures 19 and 20 are respectively a section and a part-plan of a modification
of the movable dials of the counter.
The counter so shewn on Figures 1 to 4 is provided with a certain number
of fixed dial-plates A, B, C, D, and E, upon which are respectively arranged
Figures 3 and 2-movable dials a b c d and e. The fixed dial-plate A, Fig. 1,
belongs to an upper plate P solidly fastened on the pillars p p p p of a fixed
ratchet wheel or plate P¹ which will be referred to hereafter and which is shewn

page_text: on Figures 7 and 8; this fixed dial in the shape of a crown, is divided into, for
example, 24 compartments marked respectively 2-1-1-2-2-3.
and one of which a¹ being perforated, serves as a window and allows the
particular number on the corresponding movable dial al which is opposite, to
be seen. The numbers or figures in question indicate pence or halfpence.
The fixed dials B, C, D, and E are arranged in the interior of the crown-
dial A and are respectively controlled by the square ends which terminate the
axes or rods p₁ p¹ p¹ p¹, fixed to the before mentioned ratchet plate PI; they
are divided, each into a certain number of compartments one of which serves as
a window to allow the numbers or figures of the movable dials b c d and e to
be seen, which latter are respectively underneath the said fixed dials.
The windows in question are respectively marked b¹ c¹ d¹ and e¹, see Figure 1.
The dial B, Fig. 9, contains 20 compartments marked 1 to 20 and intended
for shillings. The dials C, D and E, each comprise 10 compartments marked 1
to 10 and represent units, tens and hundreds of pounds according to the dial to
which they belong.
The movable dial a belongs, Figs. 2, 4, & 5 to the cage of the mechanism;
it is formed as a crown divided into 20 compartments marked like those of the
fixed dial A and is connected by cross-pieces 9 9 9 9 9 to the plate Q. At
its periphery is a flange a having a number of notches a³ equal to the com-
partments of the said crown a.
The movable dials b c d and e are located in recesses or sunk portions of the
upper plate P, and are respectively solid with the parts i iii, referred to later
and seated on the axes or pivots p₁₁ before mentioned; they are
divided, Figure 11, into as many compartments as the fixed dials B, C, D,
and E under which they respectively are, and are marked in the same manner.
Their peripheries are furnished with flanges r having notches r¹, equal
numerically to the compartments which they respectively possess. The flanges r
and a are in relief from the graduated bottom so as to form a cup within which
the corresponding fixed dial is boxed, as shewn on Fig. 2.
These notched flanges are provided with any kind of a guide-mark which
allows of quickly perceiving the position of the zero of the movable dials, hidden
01 concealed as stated above, by the corresponding fixed dials; this guide-mark
consists in the example shewn, of two black marks or points placed one on each
side of the notch which corresponds to zero.
It facilitates setting back to zero. Under each of these flanges is a ring m
Fig. 12, furnished with a notch or groove m¹, shaped as an inclined plane,
the part or rôle of which is indicated later; all the rings m are fixed i.e. they
are attached to the bottom of the hollows or recesses formed in the plate P and
in such a manner that the said notch m¹ is opposite the window of the corre:
sponding fixed dial.
From the foregoing it will be at once perceived that there are two essential
portions of the mechanism; the one is fixed and comprises the disc-ratchet P¹,
the upper plate P and the dial-plates A, B, C, D, E, the other is movable
and comprises the plate Q and the dial a forming the cage of the mechanism,
as also the dials b c d and e. The fixed portion is seated at and fixed by means
of screws to the base G of a casing G¹, which latter can be of any desired
shape and may be ornamented as desired, whilst the movable portion or cage
is adjusted in a rebate g of the base G and can be revolved.
The ratchet-plate Pi of the fixed portion is furnished with as many teeth as
the dial a has compartments (24 for example) and with these teeth engages
a spring-actuated pawl h mounted on the plate Q of the before mentioned cage.
This click or pawl device has for object to maintain the said cage and conse-
quently the movable dial a in the different successive positions which it can
assume with relation to the plate-ratchet P with which it is secured to. the
fixed dial A.
The plate ratchet P¹ serves as a support to the groups of wheelwork equal in

page_text: number to that of the interior movable dials, for example, to the number of
four.
These movements of sets of wheelwork correspond to the before-mentioned
axes or rods p¹ p¹ p¹ p¹ on which are seated the fixed dials B, C, D, E, and on
which are located the parts i respectively solid with the movable dials b c d e.
Each of them is formed:-of a movable dial bede, Fig. 11, solid with a
socket i, Fig. 13, which is nothing else than the previously mentioned part
seated on the fixed axis or pivot p and which connects it to a disc j, Fig. 14,
furnished with a tooth j¹; of a ratchet k solid with the disc j and with the
teeth of which a spring-pressed pawl engages, said pawl being mounted on a
support which, for the group of wheelwork-movements of the shillings" dial
is a ratchet wheel having 20 teeth (Fig. 16) and which for the sets of wheel-
work-movements for the "pounds" dial, is a wheel U, Fig. 18, having 10 pairs
of teeth. These different parts are arranged, the one as regards the other, in
the order shewn by Figures and 4, and it will be remarked, besides, that the
set of parts belonging to the dial e does not contain a disc having tooth j. It
will also be remarked that the part or ratchet wheel 7 of the movable "shillings"
dial 6 is operated in the following manner by the tooth or pointer L mounted on
the plate of the cage carrying the movable dial a and being spring-controlled.
At each complete turn of the movable dial a this tooth or pointer L (Figure 6)
meets the inclined plane of a piece G2 fixed interiorly to the casing G¹ and oppo-
site the window a¹ of the fixed dial A. Owing to the movement of rotation, it
enters one of the teeth of the ratchet and causes this latter to advance by one
division or tooth and consequently the movable dial 6 by one number.
The difference which results from this arrangement must therefore be shewn.
Whilst the dials c d e are rotated by the tooth j of the disc j, acting at a given
moment on the 10 toothed wheel of the set immediately above, the movable
dial b is itself operated by the tooth L of the dial plate of the set immediately
beneath, acting by means of the piece G2 on the ratchet of the before men-
tioned movable dial 6. In short, the tooth L is to the dial a what the disc j
having tooth is to the dials b c and d.
This is how the arrangement works.
Suppose all the movable dials a b c d and e are at zero, i.e. that the zero
of each dial appears at the windows of the corresponding fixed dials. Suppose
also that the sum of £1-10-6 has to be registered.
"
The operator furnished with any suitable sort of pointer engages at the
bottom, the end thereof in the notch r¹ of the movable dial of the "pounds
units (dial c) placed opposite the number 1 of the corresponding fixed dial C,
and causes the said movable dial to turn until the pointer in question falls into
or strikes the notch m¹ of the before-mentioned ring m. Under these condi-
tions the Figure 1 of the movable dial c appears at the window c¹. The same
operation is performed upon the movable "shillings" dial b which is so rotated
that its figure 10 is brought opposite the window 61 of the fixed dial B. I pro-
ceed in the same fashion for the movable "pence" dial a which I turn so that
the figure 6 appears opposite the window a of the fixed dial A. It should be
remarked that the operation can be reversed, that is, may be commenced at the
pence" dial and finish at the "pounds" dial," which does not affect the final
result. For any other sum I proceed in corresponding fashion.
66
It will be noted that each time a movable dial makes a complete revolution,
it acts by means of its tooth L or j¹ on the piece or ¹ of the dial of the set
immediately above, in such a manner as to cause this dial to be revolved to the
extent of one division.
The result is that the various sums successively added or registered, are
totalised, whatever be the order in which the movable dials are operated, as
stated above.
.:
It is however convenient to explain how the action of the tooth of any one
of the movable dials is transmitted to the dial of the immediately higher set.
When for instance, the finger or tooth L of the "pence" dial "meets the

page_text: This example, refer to Sheet 2 of the drawings, assumes an arrangement of
the dials other than the preceding. They are now placed in a single line and
for the manipulation of each of the movable dials, there is no need of a separate
point.
Considering the one of them, the movable dial is formed of as many flexible
radial strips or plates a leading from a centre A, as the said dial should have
divisions. The centre A is fixed as in the first model (Sheet 1) on a socket
mounted on an axis or pivot fixed in the lower plate supporting the whole
arrangement. Each strip or plate a is capable of itself bearing the number or
figure of the movable dial which I have shewn juxtaposed securely to the centre,
similar in that respect to those of Model No. 1.
Each of the strips is fitted with a button for the purpose of manipulating
'the movable dial, and which for the strip corresponding to the cipher or zero is
cross-ruled or cross-hatched as shewn in Figures 1 and 4. The outer end of these
strips is partly folded over so as to form a wedge bearing against the ring m
having an inclined plane, Model No. 1, and capable of abutting against the notch
resulting from the inclination as above stated for the manipulating point. This
folded wedge might be replaced in any suitable manner by a fixed point under
the strip.
In short, the movable dial is furnished with as many wedges or manipulating
points as it has divisions.
The ring having an inclined plane is fixed to the bottom of a cup adjoining
the cover of the apparatus. In an economical construction, this ring might be
dispensed with and the bottom of the cup formed with a notch opposite the
window of the fixed dial, in which the wedge of the strip would abut and would
serve as a support to these same wedges.
Another characteristic detail which I have adopted, is the interposition
between the controlling devices and the connecting arrangements of the different
dials between them, of toothed wheels for the purpose of causing the said dials
to turn in the same direction as shewn on Figures 2 and 6, wherein each of the
devices has been half shewn so as to better demonstrate the shape and working
thereof.
Sheets 2 and 3, Figures 4, 5, and 6.
A is a movable dial formed of flexible radial strips or segments a; a¹ is a
dial numbered according to each of the flexible strips, and secured to the centre;
as folded over part forming wedge, at the outer end of each strip; a³ is the
manipulating button.

page_text: B is a fixed dial mounted perpendicularly to the axis carrying-dial c, and
having between the 1 and the 9 a window through which the number of the
movable dial appears.
D. Cup fixed to the cover E and serving as support to the ring F having an
inclined plane; (the inclined plane going from f to f¹ where abuts the wedge
or point of the flexible strip of the movable dial).
G. Socket carrying at the upper end the movable dial, and at its lower end
the ratchet H and toothed wheel I.
H. Ratchet opposing by means of its click h the movement rearwards i.e. to
the left, of the movable dial. This arrangement is necessary to the first dial
only.
I. Toothed wheel fixed to the ratchet H and engaging a similar wheel I¹;
this latter is mounted on the intermediary axis C.
J. Disc having a tooth and secured to the wheel I' and controlling the wheel
which has ten pairs of teeth K (see Fig. 5).
K. Wheel having ten pairs of teeth, loose on its axis and having a pawl.
L. Ratchet fixed to the socket of the movable dial No. 2, and operated by
the click k.
I. Toothed wheel similar to I and I¹ mounted on and secured to the ratchet
I on the socket of the movable dial No. 2.
P. Plate on which are mounted the axes carrying the various mechanisms.
Q. Casing of the apparatus.
The working is similar to that described for Model No. 1, with this difference
that it is sufficient to press on the button in question and to bring it opposite
the window of the fixed dial; the wedge of the flexible strip reaching the in-
clined plane causes this to give slightly and abuts against f.
Each dial also works separately and the transmission from one dial to the
following is effected as described for Model No. 1 and, as in the foregoing
model, the registering of the numbers can be effected in any desired order.
Figures 19 and 20, Sheet I, represent a movable dial actuated in such a
manner that the operator need not have recourse to a separate pointer to work
the counter. In these figures, the dial properly speaking is composed of as
many flexible radial strips o leading from a centre of as the said dial must have
divisions The centre o¹ is fixed like the before mentioned movable dials in the
dial carrier which in the previous case carries the letter of the dial itself. The
outer end of each of the said flexible strips has a small pointed buttons bearing
upon the previously mentioned ring m and capable of entering a notch m¹ of this
latter as above described for the manipulating point. Briefly the movable dial
has as many manipulating points as it has divisions; it is the principle of the
preceding applied to type No. 1.
MODEL No 3. SHEET 3.
This example combines the principles of No. 1 by the exterior crown and No. 2
by the formation of the dials within this crown.
In designing it, I have had regard to a rapid totaliser for cash or counter
work, which I have shewn on Sheet 3 applied to the French monetary system;
but it can be easily modified for others according to the above.
In this model and with regard to the example selected, the outer crown A and
the movable dial a contain a double number of divisions of centimes. This
arrangement has been adopted so that the operator has to cause the hand or
ever M to traverse only a portion of the circumference to register his numbers
or figures. The fixed dial B is shewn concentrically, with the movable crown A.
and occupies only one half of the right of this latter. A window has been formed
n the upper plate of the casing of the apparatus, at one of the ends of the sector
orming the fixed dial for the appearance in succession of the numbers of the
novable dial. The notches of the outer crown of Model No. 1 are here replaced
ov blocks or pillars c drilled centrally, in which holes the stud m of the handle M

page_text: J
can engage. The operator pushes the stud of this handle which is furnished
with a suitable grip, into the one of these holes e corresponding to the number .he
wishes to register and revolves the handle until he meets the abutment of the ring
having an inclined plane, as above described, Model No. 1, opposite the window,
as stated for the separate point.
"
It is understood that this exterior crown can also be provided with engage-
ment notches which the stud of the handle could enter.
The control of the dial or the set immediately higher to the centimes,. and of
the units of francs is effected in the same manner as for No. 1.(by a tooth acting
on a ratchet, at a given moment as for the pence and shillings). The control of
the other dials by that of the units of the set immediately lower, can be obtained
as described for No. 1 or that used in Model No. 2, i.e. with the interposition of
the wheels fully toothed.
The handle has its pivot fixed to the casing of the apparatus. The buttons
or cross-hatched blocks c c shewn on Sheet 3 of the drawing indicate the zeros
of the movable dial. On this drawing only 3 small dials have been set out but
any other number of them can be used. The construction of the movable dials
of these inner dials is as described for Model No. 2.
This apparatus can rest on a socket, pedestal or other suitable support.
I, GEORGES LAFOND, of 34, Faubourg St. Martin, Paris, France, 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 follow-
ing statement:-
This invention relates to mechanical counters or adding-apparatus, sometimes
known as totalisers and cash registers."
66
"
"
It has for object to cause these counters or registers to totalise the numbers
of one or more units and their sub-divisions. The improvements comprise cer-
tain, particular mechanical arrangements, and the general working of these
arrangements, in such a manner that they are embodied in a concise form and
that their manipulation is easy.
Mechanical counters or adding-apparatus constructed according to my inven-
tion can be based on the decimal or duodecimal system, or any other system of
numeration applied to a monetary or other system. As examples, I have shewn
upon the drawings accompanying my Provisional Specification,
1. A model based on the duodecimal system in the shape of a watch although
this counter can be made in any other shape.
2., A model based on the decimal system for any sort of totalisation.
3. A model based on the French monetary system.
On the first drawing, Sheet 1, Figure 1 is a front view of this adding apparatus.
Figure 2 is a cross section made on line 2-2 of Figures 1 and 4. Figure 3
is another elevation, in which the casing and the fixed dial-plates of the counter
are supposed to be removed, so that only the movable dials can be seen.

page_text: Figure 4 is a third elevation, in which the upper plate serving as a support to
the movable dials is removed, so as to show the interior mechanism with all the
wheel-work or movements therein contained, the said mechanism being held
in a special cage which is located in one piece with the case or casing of the
counter.
Figures 5 and 6 are respectively a cross-section and a plan-view of the cage
supporting the mechanism of the counter.
Figures 7 and 8 are respectively a cross-section and a plan-view of a support
on which the various movements or sets of wheelwork are arranged to operate.
Figures 9 to 17 inclusive shew, in section and in plan, the various components
of one of these movements or sets of wheelwork.
Figure 18 shews, in section and in plan, a device special to certain of these
movements.
Figures 19 and 20 are respectively a section and a part-plan of a modification
of the movable dials of the counter.
.
The counter or adding-apparatus so shewn on Figures 1 to 4 is provided with
a certain number of fixed dial-plates A, B, C, D and E, upon which are respec-
tively arranged-Figures 2 and 3-movable dials a b c d and e. The fixed dial-
plate A, Figure 1, belongs to an upper plate P solidly fastened on the pillars
P P. of a fixed ratchet wheel or plate 1" which will be referred to hereafter
and which is shewn on Figures 7 and 8; this fixed dial, in the shape of a crown,
is divided into, for instance, 24 compartments marked respectively 1-1-1-
2—2—3—
and one of which a being perforated serves as a window
and allows the particular number on the corresponding movable dial a¹ which
is opposite, to be seen. The numbers or figures in question indicate pence and
half-pence.
The fixed dials B, C, D, and E are arranged in the interior of the crown
dial A and are respectively controlled by the square-ends which terminate the
axes or rods fixed to the before-mentioned ratchet-plate P¹; they are
divided each into a certain number of compartments one of which serves as a
window to allow the numbers or figures of the movable dials b c d and e to be
seen, which latter are respectively underneath the said fixed dials.
The windows in question are respectively marked b₁ c d and el, see Figure 1.
The dial B, Figure 9, contains 20 compartments marked 1 to 20 and intended
for shillings. The dials C, D and E each comprise 10 compartments marked 1
to 10 and represent units, tens and hundreds of pounds, according to the dial
to which they belong.
The movable dial a belongs, Figures 2, 4 and 5, to the cage of the mechanism;
it is formed as a crown divided into 24 compartments marked like those of the
fixed dial A and is connected by cross pieces qq to the plate Q. At its periphery
is a flange a² having a number of notches a equal to the compartments of the
said crown a.
The movable dials b c d and e arc located in the recesses or sunk portions of
the upper plate P, and are respectively solid or integral with the parts i ii,
referred to later, and seated on the axes or pivots 17 before mentioned; they
are divided, Figure 11, into as many compartments as the fixed dials B, C, D
and E under which they respectively are, and are marked in the same manner.
Their peripheries are furnished with flanges having notches equal
numerically to the compartments which they respectively possess. The flanges r
and a² are in relief from the graduated bottom so as to form a cup within which
the corresponding fixed dial is boxed, as shewn on Figure 2. These notched
flanges are provided with any kind of a guide mark which allows of quickly
perceiving the position of the zero of the movable dials, hidden or concealed
as stated above, by the the corresponding fixed dials; this guide mark consists
in the example shewn, of two black marks or points placed one of each side of
the notch which corresponds to zero. It facilitates setting back to zero. Under
each of these flanges is a ring m, Figure 12, furnished with a notch or groove m',

page_text: i
shaped as an inclined plane, the part or role of which is indicated later; they are
attached to the bottom of the hollows or recesses formed in the plate P and in
such a manner that the said notch m³ is opposite the window of the correspond-
ing fixed 'dial.
.
From the foregoing it will be at once perceived that there are two essential
portions of the mechanism; the one is fixed and comprises the disc-ratchet P¹,
the upper plate P and the dial-plates A, B, C, D and E; the other is movable
and comprises the plate Q and the dial a forming the cage of the mechanism,
as also the dials b, c, d and e. The fixed portion is seated at and fixed by means
of screws to the base G of a casing G¹, which latter can be of any desired
shape and may be ornamented as desired whilst the movable portion or cage is
adjusted in a rebate g of the base G and can be revolved.
The ratchet-plate P₁ of the fixed portion is furnished with as many teeth as the
dial a has compartments (24 for example) and with these teeth engages a spring-
actuated pawl mounted on the plate Q of the before-mentioned cage. This
click or pawl device has for object to maintain the said cage and consequently
the movable dial a in the different successive positions which it can assume with
relation to the plate ratchet P₁ with which it is secured to the fixed dial A.
The plate ratchet PI serves as a support to the groups of wheelwork equal in
number to that of the interior movable dials, for example, to the number of four.
These movements or sets of wheelwork correspond to the before-mentioned
axes or rods p¹¹ on which are seated the fixed dials B, C, D, and E and on
which are located the parts respectively integral with the movable dials b, c, d c.
Each of them is formed; of a movable dial bede, Figure 11, integral with
a socket i, Figure 13, which is nothing else than the previously men-
tioned part seated on the fixed axis or pivot p₁ and which connects it to a
disc, Figure 14, furnished with a tooth of a ratchet k solid with
the disc and with the teeth of which a spring-pressed pawi engages, said
pawl being mounted on a support which, for the group of wheelwork movements
of the "shillings" dial, is a ratchet wheel 7 having 20 teeth (Figure 16) and
which for the sets of wheelwork-movements for the "pounds" dial, is a wheel 11,
Figure 18, having 10 pairs of teeth. These different parts are arranged the one
as regards the other, in the order shown by Figures 2 and 4, and it will be
remarked, besides, that the set of parts belonging to the dial e does not contain
a disc having tooth j¹. It will also be remarked that the ratchet-wheel / of
the movable shillings" dial b is operated in the following manner by the tooth
or pointer L mounted on the plate Q of the cage carrying the movable dial a
and being spring controlled.
At each complete turn of the movable dial a, this tooth or pointer L, Figure 6,
meets the inclined plane of a piece G² fixed interiorly to the casing G¹ and oppo-
site the window a¹ of the fixed dial A. Owing to the movement of rotation, it
enters one of the teeth of the ratchet and causes this latter to advance by one
division or tooth and consequently the movable dial 6 by one number.
The difference resulting from this arrangement must therefore be shewn.
Whilst the dials c d e are rotated by the tooth j' of the disc j, acting at a given
moment on the 10-toothed wheel of the set immediately above the movable
dial is itself operated by the tooth L of the dial plate of the set immediately
beneath, acting by means of the piece G² on the ratchet 7 of the beforementioned
movable dial b. In short, the tooth L is to the dial a what the disc j having
tooth is to the dials b, c, d.
This is how the arrangement works.
Suppose all the movable dials a bed and e are at zero, i.e., that the zero of
each dial appears at the windows of the corresponding fixed dials. Suppose
also that the sum of £1-10-6 has to be registered. The operator furnished with
any suitable sort of pointer engages at the bottom, the end thereof in the notch r¹
of the movable dial of the "pounds" units (dial c) placed opposite the number 1
of the corresponding fixed dial C, and causes the said movable dial to turn until

page_text: ور
the pointer in question falls into or strikes the notch m¹ of the before-mentioned
ring m. Under these conditions, the figure 1 of the movable dial c appears at
the window c. The same operation is performed upon the movable "shillings'
dial 6 which is so rotated that its figure 10 is brought opposite the window b₁
of the fixed dial B.
I proceed in the same fashion for the movable "pence" dial a which I turn
so that the Figure appears opposite the window a¹ of the fixed dial A. It
should be remarked that the operation can be reversed, that is, may be com-
menced at the " pence" dial and finish at the "pounds" dial, which does not
affect the final result. For any other sum, I proceed in corresponding fashion.
It will be noted that each time a movable dial makes a complete revolution
it acts by means of its tooth L or on the piece or of the dial of the set
immediately above, in such a manner as to cause this dial to be revolved to
the extent of one division.
The result is that the various sums successively added or registered, are
totalised whatever be the order in which the movable dials are operated, as
stated above. It is, however, proper to explain how the action of the tooth j¹
of any one of the movable dials is transmitted to the dial of the immediately
higher set.
When, for instance, the finger or tooth L of the " pence" dial meets the
piece or wheel of the "shillings" dial, this tooth L causes the said wheel to
revolve to the extent of one tooth and this partial rotation is transmitted to the
ratchet by the pawl and thence to the movable shillings" dial 6 fixed
to the said ratchet k. It is the same for the tooth j¹ of the other dials with
relation to the wheel of the dials of the set immediately higher. It will,
however, be remarked that this transmission cannot take place in the opposite
direction by reason of the method of connection carried out by the click
device and also that the ratchet is rendered immovable in each position
which it assumes by means of a retaining pawl h whilst the wheels are locked
by the fixing of the corresponding disc between the two pairs of teeth which
are opposite it.
As is evident, my counter or register allows me to add or to totalise with the
greatest facility, any sums whatever. In case of the counter shewn, totalising
can be effected up to £1000.
It is to be understood that although in the foregoing I have considered a
counter or register having dials graduated according to the English or duodecimal
coinage, I can divide out the said dials according to the French monetary or
decimal system, which difference does not necessitate departure from the prin- .
ciple of my invention.
In order to simplify the mechanism for actuating or driving the movable dials,
1 have adopted the new arrangement shewn on drawings attached to this specifi-
cation, and designated. Sheet 1*. Figure 1* is a plan; Fig. 2 is an elevation
looking towards lines C-D) of Fig. 1*, and Fig. 3* is an elevation looking
towards line A-B of Figure 1*.
As already described, the "shillings" wheel bis driven forward one division
at each complete turn of the plate Q actuated by means of the notches a³ and
that by means of the finger L when it meets the abutment G fixed to the
interior of the casing G¹.
This wheel transmits in its turn and successively to each of the wheels c d e
which represent the units, tens and hundreds of pounds which are driven for-
ward one division at each complete revolution of the preceding wheel. From this
point the following modification may be made. The subsequent reference

The movable plate j of the "shillings" wheel is fitted with a snail A, Fig. 1*,
which turns therewith when it is driven by the "
pence "wheel. Upon the
curve of the snail bears the end B of one arm of a bell-crank lever pivoted at B.
The other arm B is fitted at its end with a pawl bengaging a toothed

page_text: a folded over portion forming wedge, at the outer end of each strip; a³ is the
manipulating button.
B is a fixed dial mounted perpendicularly to the axis carrying-dial c and having
between the 1 and the 9 a window through which the number of the movable
dial appears.
1 cup fixed to the cover E and serving as support to the ring F having an
inclined plane; the inclined plane going from f to f¹ where abuts the wedge or
point of the flexible strip of the movable dial.
C socket carrying at the upper end the movable dial, and at its lower end the
ratchet H and toothed wheel I.
H. Ratchet opposing by means of its click h the movement rearwards i.e., to
the left, of the movable dial. This arrangement is necessary to the first dial
only.
I toothed wheel fixed to the ratchet H and engaging a similar wheel I'; this
latter is mounted on the intermediary axis C¹.
J. Disc having a tooth j and secured to the wheel I'; controlling the wheel
which has ten pairs of teeth K, see Figure 6, Sheet 3.
K. Wheel with ten pairs of teeth, loose on its axis 2 and having a pawl k.
L. Ratchet fixed to the socket of the movable dial No. 2 and operated by the
click k.
I. Toothed wheel similar to I and I¹ mounted on and secured to the ratchet on
the socket of the movable dial No. 2.
P. Plate on which are mounted the axes carrying the various mechanisms.
Q casing of the apparatus.
The working is similar to that described for Model No. 1, with this difference
that it is sufficient to press on the button in question and to bring it opposite
the window of the fixed dial; the wedge of the flexible strip reaching the inclined
plane causes this to give slightly and abuts against f¹.
Each dial also works separately and the transmission from one dial to the
following is effected as described for Model No. 1, and, as in the foregoing model,
the registering of the numbers can be effected in any desired order.

Figures 19 and 20, Sheet 1, represent a movable dial actuated in such a
manner that the operator need not have recourse to a separate pointer to work
the counter. In these figures, the dial properly speaking is composed of as many
flexible radial strips leading from the centre o¹ as the said dial must have
divisions. The centre o¹ is fixed like the before-mentioned movable dials in the
dial-carrier which in the previous case carries the letter of the dial itself. The
outer end of each of the said flexible strips has a small pointer button s bearing
upon the previously mentioned ring m and capable of entering a notch m¹ of
this latter as above described for the manipulating point. Briefly the movable
dial has as many points as it has divisions; it is the principle of the preceding
applied to type No. 1.
MODEL No 3. SHEET 3.
This example combines the principles of No. 1 by means of the exterior crown,
and of No. 2 by means of the formation of the dials within this crown.
In designing it, I have had regard to a rapid totaliser for cash or counter work,
which I have shewn on Sheet 3, applied to the Frech monetary system; but it
can be easily modified for others according to the above.
In this model and with regard to the example selected the outer crown A and
the movable dial a contain a double number of divisions of centimes. This
arrangement has been adopted so that the operator has to cause the handle or
lever M to traverse only a portion of the circumference to register his numbers
or figures. The fixed dial B is shewn concentrically with the movable crown A
and occupies only one half of the right of this latter. A window 6 has been
formed in the upper plate of the casing of the apparatus, at one of the ends of
the sector forming the fixed dial for the appearance in succession of the numbers
of the movable dial. The notches of the outer crown of Model No. 1 are here

page_text: replaced by blocks or pillars c drilled centrally in which holes the stud m of the
handle M can engage. The operator pushes the stud of this handle which is
furnished with a suitable grip, into the one of these holes e corresponding to
the number he wishes to register and revolves the handle until he meets the
abutment of the ring, having an inclined plane, as above described, Model No. 1,
opposite the window as stated for the separate point.
It is understood that this exterior crown can also be provided with engagement
notches which the stud of the handle could enter.
The control of the dial or set immediately higher than the centimes, and of the
units of francs is effected in the same manner as for No. 1 (by a tooth acting
on a ratchet, at a given moment, as for the pence or shilling). The control of
the other dials by that of the units of the set immediately lower, can be effected
as described for No. 1, or for that of No. 2, i.e., with the interposition of wheels
fully toothed.
The handle has its pivot fixed to the casing of the apparatus. The buttons or
cross hatched blocks cc shewn on Sheet 3 of the drawings indicate the zeros of
the movable dial. On this drawing, only three small dials have been set out,
but any number of them can be used. The construction of the movable dials
of these inner dials is as described for Model No. 2.
The apparatus can rest on a socket pedestal or other suitable support.
I may adjoin to any of the forms of the above adding apparatus, for counter
use, shop work and the like, any of the ordinary machines or means for imprint-
ing on a band of paper, or ticket, the various sums added successively; and I may
provide means for preventing tampering with the adding apparatus, such means
comprising, for instance, keys or plugs for insertion into the apparatus and to
be kept when not in use by the person controlling the same.
These devices may
be of any well known type and I make no special claim thereto.
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:-
1. In adding apparatus for adding units and sub-divisions of monetary or
other value, the combination for each kind of indications of two superposed dials
graduated in the same manner, the one being fixed and intended to serve as a
guide-mark and having a window at its zero division; the other being movable
and having a notched Hange or provided with pierced blocks, in agreement with
its divisions and with those of the fixed dial; of a circular path provided with
a notch in an inclined plane situated opposite the window of the fixed dial;
of a pointer, rod or handle intended to be engaged in the notch or pierced block
opposite a given division of the fixed dial and intended to cause the movable dial
to turn until the said pointer, rod or other implement is stopped by the inclined
plane of the said circular path, with the effect of imparting to the said movable
dial an angular movement equal to the angle contained between the given division
of the fixed dial and the window of the latter, substantially as described.
2. In adding apparatus for adding sub-divisions and units of monetary or
other value, the combination for each kind of indications of a set of wheel-
work comprising;-a movable dial located under a fixed dial integral with a
disc having a driving tooth j and with a ratchet wheel and with a toothed
wheel or receiving an intermittent motion from an adjacent set, for instance,
by means of the finger j' of the disc j of the said set and transmitting it by a
pawl to the ratchet & and consequently to the movable dial; the said combination
having for objects to submit each movable dial to the action of that one of the
order or set immediately beneath and to cause it to act upon that of the order
immediately above, whilst preserving its independence, that is, whilst leaving it
free to be actuated directly by hand, and also the motion of tooth L of a
ratchet and therefore of the corresponding movable dial, this tooth and this
ratchet being arranged as described with reference to Model No. 1.

page_text: 3. In adding apparatus, the combination of a series of fixed dials A B C D E
having windows, the said diàls being integral with an upper plate P and with a
ratchet wheel P1 with a corresponding number of movable dials a b c d e located
under the said fixed dials and provided with a notched flange allowing them to
be turned by hand by means of a pointer, and with wheel work of the kind
claimed in Claim 2, intended to connect each movable dial with that of the set
immediately above, substantially as described.
4. In adding apparatus, the special arrangement of movable dials provided
with flexible radial strips equal in number to that of their divisions, the said
strips each possessing a pin or wedge intended to make friction with the circular
path or ring m and to engage a notch m¹ with the result of stopping in their
revolution the said movable dials at the time the said pin or wedge attains a
position opposite the window formed in the fixed dials, substantially as above
described.
5. In adding apparatus, the combination of a method of driving the "pounds"
dials from the "shillings" wheel by means of a snail, of a bell-crank lever and
of a pawl operating the "pounds" unit dial; the "pounds" tens and hundreds
being driven by intermediary wheels d and e in always the same direction, sub-
stantially as described and illustrated on Sheet 4 of the drawings.
6. Adding apparatus, constructed, combined and arranged to work, substantially
as herein described and as illustrated on the respective sheets of drawings.
