Mechanism in connection with a Cash Registering Apparatus for
Making Visible and Adding Together the Separate Amounts
Received.
I CHARLES BRADBURY of 249 High Holborn, London, W.C., Agent, 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 :-
The arrangement of the apparatus is illustrated in Figs. 1 to 5. Fig. 1 is a
section through V and VI of the plan Fig. 3, Figure 2 is a section through III
and IV of Fig. 1, and Figs. 4 and 5 show details of the mechanism for adding the
total.
The apparatus shown is arranged for adding amounts of five figures, but the
sum total may reach to six figures.
The five columns of figures are distinguished by means of the small numerals.
placed after the alphabetical signs,-a', ', &c. representing details in the column
of units, a, b, &c. those in the tens, &c.
The setting in motion of the parts which render the respective figures visible is
effected by a separate action for each column, but the mechanism is the same in
each of the five actions, which are distinguished by the small numerals 1 to 5
placed after the reference letters.
It will thus be unnecessary to repeat the above named distinguishing numerals
in describing the whole series of actions.
If, when the mechanism stands at its zero position, the key or knob of one of the
toothed bars (a) be pressed downwards, thus forcing back, by the inclined plane at
its lower extremity, the presser bar with spring (i) Fig. 1, the teeth of (a) will
engage with the toothed wheel (k) fixed on the shaft (r).
The latter will thus be caused to revolve according to the length of stroke
given to (a). The toothed bars are shaped as shown in section in Fig. 3, and slide
in the grooves provided in the frame, (f) and (h).
The driving disc (u) fixed on the shaft (r) turns with the latter, and is provided
with a pin. This is connected by a link (l, Fig. 1) with the pin fixed on the
slide (c).
The link (1) has a slot in its centre and slides on a movable fulcrum which turns
on the shaft (d). The slide (c) moves in a dove-tailed slot on the disc (o), which
thus responds to the movements of the pin attached to (c).
As shown in Fig. 2, the disc (o) is fixed to the same shaft as the disc (s). This
bears on the side nearest the purchaser, the figures 0 to 9, which can be seen
through the opening (A), and, through the mechanism described above, follows the
movements of the toothed bar (a).
The zero position of the mechanism is determined by the stop (Z), against
which a projection on the disc (o) finds its resting position.
To make visible at the aperture (A) any given number, by means of the shaft (r),
nine toothed bars have been provided for each column of figures, these bars slide
in the vertical slots (f) on the upper frame, and (h) on the lower frame.

page_text: The slots (f) vary in height, being arranged in graduated stages, and the
distance in each case between the under surface of the knob on a toothed bar and
the upper surface of the slot (f), corresponds with the distance which the toothed
bar requires to move in order to render visible at (A) the figure marked on the
knob of the toothed bar (Fig. 3).
The other eight toothed bars of the same column will not participate in the
action of the ninth which is depressed, because, by means of a pin (i), which
presses its inclined surface against their lower extremity, they are supported so
that their teeth cannot engage with those of the wheels (k)-see position of second
column in Fig. 1.
The disc (p) fixed on the shaft (7) carries on its cylindrical surface the
figures 0 to 9, one of which can be seen at the opening (B), thus indicating to the
operator the figure made visible at (A).
The disc (m, Fig. 2) which, like the dise (p), is also provided with figures, bas
equally shared in the turn given to (r).
The spiral spring (9) tends to turn the shaft () in the opposite direction to that
caused by the toothed bar (a), but the entire mechanism is now maintained at the
desired position by the ratchet wheel (g) which is held by the catch (n).
This ratchet wheel has ten teeth, which exactly correspond with the figures
which are made visible at the openings (A) and (B).
The apparatus is arranged to render visible amounts of five figures, of which in
the drawings, the two last (indicated by 1 and 2) represent the centimes or
phennigs, and the three others (marked 3, 4, 5) the units, marks or franes.
Now, the purchaser and the vendor being face to face, it would be necessary to
read the figures at the apertures (A) in the reverse order, if the movement of the
shaft () to the extreme right of Fig. 1 were not transmitted to the disc (s¹) on
the extreme left. Therefore, the connecting rods (1) are made to cross each other,
the fulcrums on which they slide being placed side by side on the one shaft (d).
This also determines the disposition of the driving discs (u) and (o) in the plan
(Fig. 3), and the form of the framework (a) and (y).
As already stated, the spiral spring (9) has been wound by the turning of the
shaft (r), and that, the pressure ceasing on the knob of the toothed bar (a), the
mechanism of each column of figures is retained in the desired position by the stop
wheel (g). Now, if the catches (n) be withdrawn from the ratchet wheels, all the
five columns of figures will, by the force of the spring (9), be brought to the
zero position, determined by the stops (Z).
For this purpose is provided the shaft (t, Figs. 2 and 3), on which are fixed
the lifters (w), which press under one arm of the catches (n), made in the form of
two-armed levers.
Therefore, if the shaft (t) be turned in the desired direction by the handle (v),
all the mechanism will return to the zero position, and the toothed bars (a) which
had been held down, will be forced upwards by the presser pins (i) and can no
longer engage with the toothed wheels (k).
The total adding discs are excepted from the backward movement of the
mechanism. These discs are unfixed and can revolve freely on the stopping
wheels (6 m, Figs. 4 & 5) which are fixed to the shafts (r).
In the interior of the disc (m), consisting of the disc (cm) and the frame (am)
Fig. 5, are fixed the stopping catches (dm). These only transmit the rotations of
the shaft (r) in one direction, in the contrary direction they slide over the curves
of the stopping teeth of (bm).
Here the discs (m) are maintained in the position reached, by the spring (fm).
the curved part of which presses between the driving pins (im).
Of course, it is necessary that the resistance of this spring (fm) should be
overcome by the pressure on the ioothed wheels at (a). After an entire revolution
of the disc (m), or when, turning the disc, the figure 9 is passed, the finger (km)
forces the pin (im) of the disc (m) of the next column of figures on the left, and
thus effects the carrying of units to tens, tens to hundreds, &c.

page_text: The total addition is concealed by the cover (L), which may be kept fastened, so
that only the holder of the key may be able to read the total shown at the
apertures (C).
The receipt of monies, as far as concerns the mechanism here described, is
effected as follows;-The vendor first presses the handle (v), thus bringing the
indicating mechanism to zero. Then he depresses the proper toothed bars and
thus causes the amount to appear in figures before the eyes of the purchaser, the
same movement likewise causes the same amount to be added to the total already
appearing under the cover (L), so that the holder of the key to this cover may at
any time ascertain the total receipts registered.
Lastly, the till may also be arranged for other monetary systems than the
decimal coinage, as for example that of the United Kingdom. It is only necessary
to augment as required the number of toothed bars (a) and to provide the discs
which serve to exhibit the figures (s, m, and p) with the requisite number of
figures.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Mechanism for rendering visible and adding together the separate sums
received, in cash registering apparatus, having the following features;
The toothed bars (a), surmounted by a knob or button, and sliding in grooves
arranged in graduated stages, acting laterally on the shafts (r), the number
of revolutions given to same being visibly indicated by the figured discs (p)
at the openings (B), by the figured discs (m) at the openings (C), and
thirdly, by means of the links (1), by the figured discs (s) at the openings (A);
being retained by the stopping wheels (9) and the catches (n) after the
movement of the toothed bars (a) have ceased.
2. In combination with the above, a disengaging mechanism, consisting of the
shaft (t) to which is attached a handle (v), which being turned, releases by the
lifters (w) the catches (n) of the stopping wheels (9), thus allowing the springs (q)
to bring each mechanism to the zero position.
3. In combination with said mechanism, a total adding device, comprising the
discs (m), turning loosely on the stopping wheels (bm), and by means of the
stopping teeth (dm) and the springs (fm), made to follow the turns of the shaft (r)
in one direction only, and provided with the fingers (km) and pins (im) for
carrying on to the next higher column of figures.
Dated this 1st day of January 1895.
