PROVISIONAL SPECIFICATION.
Improved Registering Mechanism Applicable to certain Cash
Registers and Indicators.
I, JOHN ROBERT WARD, of 11 Russell Gardens, Holland Road, Kensington,
Middlesex, Cook and Confectioner, do hereby declare the nature of this invention to
be as follows :—
This my invention has reference to an improved registering mechanism applicable to
cash registers whereby money as received by shop assistants, harmen and other
servants, is checked and the amount thereof registered upon suitable registering
mechanisin provided for that purpose. Said invention hereinafter described is
more especially applicable to my improved cash register and indicator, coin
detector, and change giving apparatus set forth in my specification thereof,
No. 17134, dated Nov. 24th 1888, in which the registering mechanism is described
as consisting of a double set of rollers or wheels, upen one set of which is coiled
a steel or other tape, said tape is further described as having inscribed thereon
a series of numbers, indicating the amount of purchase, and which tape is auto-
matically wound from off the one set of rollers upon the other set of rollers by the
operation of a set of keys forming part of the cash register aforesaid.
By this my said invention I substitute for the steel or other tapes aforedescribed,
a set of endless steel or other bands which are adapted to pass over a set of rollers
which are mounted upon two parallel shafts extending from side to side of the cash
register. Said rollers may be provided upon their periphery with suitable pins or
teeth which are equidistantly placed, and project sufficiently from the face of the
rollers, to enter a series of equidistant perforations in the steel or other bands, which
are thereby prevented from slipping. One set of the rollers aforesaid is provided
with a series of ratchet wheels which may either be formed integral therewith or
securely attached to the faces thereof. These said rollers and bands are operated by
a series of depressible key levers pivoted horizontally at their centres upon a transverse
bar, and provided upon their underside with a vertical depending arm to which is
pivoted two pawls adapted to engage with the teeth of the ratchets aforesaid; there
being one ratchet and one roller for each pawl. It will be readily understood
therefore that by depressing one end of the horizontal levers aforesaid, that the
ratchets and the rollers carrying the endless bands will be caused to rotate in
successive stages. Since however said bands are marked off with a series of numbers
representing the amount of purchase, and that said numbers on one band represent
the units, and the numbers upon the adjacent band the hundreds, it is only required
to operate the band representing hundreds, one stage after each revolution or one
hundred stages of revolution of the units band. This operation is provided for by
a depending projection upon the under side of one of the pawls aforesaid, and which
projection rides upon the band representing the units and keeps the pawl elevated
above the ratchets until said projection falls into an aperture in the band, which
allows the pawl to fall upon the ratchet and move it one stage. As the units band is
again operated the projection is again caused to ride upon the tape and throw the
pawl out of engagement with the ratchet. One set of rollers run loosely upon their
shaft, but the other set revolve upon their shaft with just sufficient friction to prevent
their rotation unless operated by the pawls as aforedescribed. Said friction is
maintained by a suitable spring provided with a regulating screw which bears with
a constant pressure against a loose collar upon the roller-shaft and in close contact
with the rollers. Mounted upon a transverse shaft extending from side to side of the
cash register, is a series of pawls which are held elevated above the rollers aforesaid by a
depending projection which rides upon the "hundreds" band. In rewinding the tapes

page_text: back to zero a suitable key or other device is applied to the shaft carrying the friction
hand-rollers, and when the shaft is revolved the rollers also by reason of the friction
will be rotated and each tape carried along until the projections upon the pawls last
named fall into suitable perforations upon the "hundre "band, and allow said pawis
to fall upon the rollers and engage with the pins aforesaid and consequently lock
further rotation.
It will be found that during the rewinding, that some of the bands will be brought
to zero before others and will be locked by the pawls as described, but in consequence
of the friction device aforedescribed each band and its rollers can move independently
of the others, until all the lands are at zero and locked in that position. By a simple
arrangement applied to the shaft carrying the locking pawls, they may be all
simultaneously elevated out of engagement with the pins upon the rollers, and the
bands and mechanism ready to be operated by the depressible keys as and in the
manner aforedescribed.

Improved Registering Mechanism Applicable to certain Cash
Registers and Indicators.
1 JOHN ROBERT WARD, of 11 Russell Gardens, Holland Road, Kensington,
Middlesex, Cook and Confectioner, 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 :-
This any invention has reference to an improved registering mechanism applicable
to eash registers whereby money as receive1 by shop assistants, larmen and other
servants is cheeked and the amount thereof registered upon suitable registering
mechanism provided for that purpose. Said invention hereinatter described is more
0specially applicable to my improved cash register and indicator, coin detector and
change giving apparatus set forth in my specification thereof No 17134 dated
Nov. 24th 1888 in which the registering mechanism is described as consisting of a
double set of rollers or wheels upon one set of which is coiled a steel or other tape,
said tape is further described as having inscribed thereon a series of numbers
indicating the amount of purchase and which tape is automatically wound from
off the one set of rollers upon the other set of rollers by the operation of a set of
keys forming part of the cash register aforesaid.
Fig. 1 is an elevation of my improved registering mechanism; and Fig. 2 is a
contracted plan thereof. Fig. 3 is a detail plan view of one of the hands. Fig. 4 is
a detail elevation of the band supporting bår. Fig. 5 is a detail front elevation of a
collar forming part of the mechanism.
By this my said invention I substitute for the steel or other tapes aforedescribed a series
of endless steel or other bands K which are adapted to pass over a set of rollers K' K²
mounted upon shafts && said rollers K' K' are provided upon their peripherios with
suitable pins which are equidistantly placed, and project sufficiently from the face of
the rollers to pass through a suries of equidistant perforations in the bands which
are thereby provented from slipping upon the face of the rollers. The set of
rollers Kare provided with a series of ratchet wheels K' which may be either
formed integral therewith or securely attached to the faces thereof by screws or other
means. Those said rollers and hands are operated by the series of depressible key
levers B having the depending arms to the extremity of which are pivotul two
pawls L L', which are adapted to engage with the teeth of the ratchets K³ there
eing one ratelet and one roller for each pawl. It will be readily understood
therefore, that when a lover B is depressed that the ratchets and rollers carrying
the endless bands will be operated in successive stages. Since however said bands are
marked off with a series of numbers representing various amounts of purcluse, and

page_text: that said numbers upon one band represent the units, and the numbers upon the adjacent
band, the hundreds, it is only required to operate the band representing the hundreds
one stage, or a distance equal to the space between the perforations in the tape, after
each complete revolution or one hundred stages of revolution of the units band.
This operation is provided for by a depending projection / upon the underside of the
pawls L, and which projection rests upon the band representing the units and keeps
the pawl raised above the ratchets until said projection falls into an aperture ♬ in the
band, which allows the pawl to fall upon the ratchet of the roller carrying the
adjacent band representing the hundreds and move it one stage with the next
operation of the levers B. When the units bind is again operated the tapering
side of the projection is caused to ride upon the tape representing the units and
throw the pawls out of engagement with the ratchets. The tape is stiffened and
supported at this place by a transverse bar L³ provided with grooves 2 for the tapes
and for the projection and projection m hereinafter described, to fall into, when
entering the perforations of the bands. The rollers K' run loosely upon the
shaft but the rollers K³ run upon the shaft & with just sufficient friction to prevent
their rotation unloss rotated by the hands K. Said friction is maintained by a flat
spring N attached to the stay-har N₁ by one of the nuts n and the spiral spring p²
which is in compression between the collars and 01. Said spring having a
regulating screw n¹, bears with a constant pressure against a collar having a
projection or feather o adapted to slide in a groove o' of the shaft k. This provision
allows the collar O' to move in a longitudinal, but not in a rotary direction upon the
shaft k, and by the pressure of the springs N and the rollers K² are kept in constant
close and frictional contact. There are also collars or washers 03 having feathers
(similar to those indicated by the letter) between each roller which serves to prevent
the rotation of one roller being communicated to the other by the friction. Mounted
upon a transverse shaft M is a series of pawls M' which are held raised above the
rollers K' by the projections in which at times ride upon the bands as hereinafter set
forth. Said pawls M are secured to the shaft M by pins & fitted into the shaft M and
projecting into the slot C in the boss of the pawl M by this means each pawl M
whon the shaft M' is turned round by the koys,) will he enabled to fall a distance
limited by the length of the slot c, independently of the shaft M. The pawis M' can
be raised by a key applied to the square portion m³, and be retained elevated by any
suitable device, such as a ratchet m and a pawl m³. In rewinding the bands back to
zero, or their starting point, a suitable key or other device is applied to the shaft k
P which will enable the rollers K' to be rotated. Before commencing to rotate the
shaft however, the pawls M' are allowed to fall with their projections m upon the
bands by releasing the pawl m³ of the ratchet m². The bands are then carried along
by the rotation of the rollers K² which revolve by reason of the friction between
them and the collars 0, 0, 0' until the projections m fall into the perforations ( of
the hands. The forward ends of the pawls M' will then fall upon the teeth ** of the
rollers K and lock them, thus preventing any further rotation; as each band is wound
so that the "zero "mark of each is brought in line opposite the aperture P in the
metal or other shield P. Although the friction between the rollers K and the
collars 0, 01, 0³, is sufficient to cause the bands to travel, each one of said rollers is
capable of remaining stationary when the bands are locked by the pawls M' whilst
the other adjacent roller or rollers rotate until similarly locked. The numbers upon
the bands may be read through the aperture P in the metal plate P' which extends
from side to side of the apparatus.
at
The bands shown in fig. 3 are marked off with numbers thus 0, 1, 2, 3, and so on
up to 99.
It will be understood therefore that when the units band or the band to
the right hand has travelled 99 stages of revolution its next movement will show
the figure 0 and the hundreds band or band to the left which has been showing 0 will
simultaneously be moved one stage and show the figure 1 which is read as 100 and
as the units band continues to rotate the reading will be 1, 2, or as read 102; 1, 3,
or as read 103 and so on until one complete revolution of the units band has been
made when the number 1 on the hundreds band will change to 2 representing 200 since I
