PROVISIONAL SPECIFICATION.
Improvements in Cash Tills.
We GEORGE RODENHURST STOKES, Managing Director, of Brunswick House,
Hanley, and THOMAS MILNES FAVELL, Engineer, of Etruria, both in the County'
of Stafford, do hereby declare the nature of this invention, to be as follows:-
This invention for improvements in cash tills relates to tills in which a band of
paper within the till is traversed automatically under a slot or opening in the lid of
the till every time the till drawer is opened and closed so that a fresh portion
of the band is brought under the opening in the lid to receive a record of the cash
transaction; and consists essentially in automatically operating the band one step
forward for each opening and closing movement of the drawer, however small or
large the movement and whatever the initial position of the drawer and in providing
means whereby the drum on which the paper band is wound can be easily removed.
from the till to remove the used band and insert the end of a new band and then be
readily. replaced with the new band in position in the till.
In one arrangement of mechanism for operating the drum on which the band is
to be wound a pawl lever is pivoted on the axis of the drum at one end and two
pawls are pivoted to this lever in such manner that the motion of one pawl on its
pivot is limited in one direction and the other pawl in the other direction. These
pawls gear in a continuous rack on the top edge of the side of the till drawer the
teeth of the rack being cut so deep that when the pawls are vertical they do not
extend quite to the bottom of the teeth. It will readily be seen that when the
drawer is moved in one direction the ratchet teeth simply rotate one pawl on its
pivot but the first ratchet tooth acting on the other pawl rotates it in the direction in
which its motion is limited and when the limit is reached rotates the pawl lever on
the drum axis until the ratchet tooth is free to pass the pawl and that on the
continued motion of the drawer in the same direction the succeeding ratchet teeth
pass the pawl without further operating the lever. On moving the drawer in the
opposite direction the lever is moved in a similar manner through the other pawl in
the opposite direction. Thus for each opening and closing movement the lever
makes a definite backward and forward motion and this motion is utilized by a
pawl and ratchet wheel or other suitable device to move the drum forward.
It will readily be seen that a single tooth is sufficient to operate the pawls as
above described and that this tooth can be so placed that the drum is operated at
any particular part of the motion of the drawer or that independent teeth may be
fixed as desired in the path of the pawls.
In order to readily remove the drum it is mounted loosely and centrally at its
driven end on a shaft or centre or other support and is driven by means of a pin or
other projection rotated round the axis of the support or centre and engaging
loosely in a hole or recess in the end of the drum; or the square or other unround-
shaped end of the driving shaft may fit into a similarly shaped hole in the end of
the drum. A spindle or axis on the other end of the drum is arranged to drop
into a V or other open bearing and may be retained by a pin, spring or similar
device.

We, GEORGE RODENHURST STOKES, Managing Director, of Brunswick House,
Hanley and THOMAS MILNES FAVELL, Engineer, of Etruria, both in the County
of Stafford, 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 invention for improvements in cash tills relates to tills in which a band of
paper within the till is traversed automatically under a slot or opening in the lid
of the till every time the till drawer is opened and closed so that a fresh portion of
the band is brought under the opening in the lid to receive a record of the cash
transaction; and consists essentially in automatically operating the band one step,
forward for each opening and closing movement of the drawer, however small or
large the movement within moderate limits and whatever the initial position of the
drawer and in providing means whereby the paper band can be easily replaced by
a new band
In one arrangement of mechanism for operating the drum on which the band is
be wound, a pawl lever is pivoted on the axis of the drum at one end and two
pawls are pivoted to this lever in such manner that the motion of one pawl on its
pivot is limited in one direction and the other pawl in the other direction. These
pawls gear in a continuous rack on the top edge of the side of the till drawer the
teeth of the rack being cut so deep that when the pawls are vertical they do not
extend quite to the bottom of the teeth. It will readily be. seen that when the
drawer is moved in one direction the rack teeth simply rotate one pawl on its pivot"
but the first rack tooth acting on the other pawl rotates it in the direction in which.
its motion is limited and when the limit is reached rotates the pawl lever on the
drum axis until the rack tooth is free to pass the pawl and that on the continued
motion of the drawer in the same direction the succeeding ratchet teeth pass the
pawl without further operating the lever. On moving the drawer in the opposite
direction the lever is moved in a similar manner through the other pawl in the
opposite direction. Thus for each opening and closing movement the lever makes
a definite backward and forward motion and this motion is utilized by a pawl and
ratchet wheel or other suitable device to move the drum forward.
It will readily be seen that a single tooth is sufficient to operate the pawls as
above described and that this tooth can be so placed that the drum is operated at
any particular part of the motion of the drawer or that independent teeth may be
fixed as desired in the path of the pawls.
In the accompanying sheet of illustrative drawings:-Fig. 1. is a sectional elevation
of a till constructed according to this invention and Fig. 2 is a sectional plan of
the same.
The band a passes from the roll over the block or table c to the drum d on
which it is gradually wound by the opening and closing of the till drawer so as to
present a fresh portion of the band opposite the opening e to receive a record of
the cash transaction. A pawl lever is mounted loosely on one end of the drum
axis and two pawls h, i are pivoted to this lever, in such manner that their free
ends are free to approach one another but cannot recede from one another beyond
the position shown in the drawing. The pawls gear in a continuous rack on the
top edge of the side of the till drawer m, the teeth of the rack being cut so deep
that when the pawls are at right angles to the rack they do not extend quite to the
bottom of the teeth. It will readily be seen that when the drawer is opened, the
rack teeth simply rotate the pawli on its pivot but the first rack tooth acting on
the other pawl h rotates the pawl lever on the drum axis until the rack tooth

page_text: escapes the pawl, the succeeding rack teeth passing the pawl without further
operating the lever.
On closing the drawer the lever f is moved in the opposite direction through the
pawl i.
The lever also carries a pawl a gearing with and actuating a ratchet
wheel o on the end of the drum. A detent p kept in gear by the spring ŕ prevents
any back motion of the drum when the pawl n is receding.
In order that the drum d can be left perfectly free when removing an old band
or inserting a fresh band, the pawl n is kept in gear with the ratchet wheel o by a
spring and can be rotated backward on its pivot through half a revolution. The
pawl p pivoted at t is also arranged to be moved out of gear by means of a pin u
on the end of a lever w fulcrummed at x, the pin acting on the notch y of the
pawl.
The end of the band is secured to the drum by means of a V or other similar
spring fitting in a longitudinal groove in the drum or any other suitable means.
The pawl
is also arranged to carry the hammer of the bell, which is thus
struck once as the drawer is opened.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In cash tills automatically traversing a band of paper within the till under a
slot or opening in the lid of the till every time an opening and closing motion is
imparted to the till drawer, the extent of motion of the band being independent of
the amount of motion of the drawer or the initial position of the drawer substantially
as described.
2. In cash tills in which a band of paper within the till is automatically traversed
under a slot opening in the lid of the till every time the till drawer is opened and
closed, the mechanism for operating the drum on which the paper is wound,
consisting of rack teeth on the drawer, of a lever mounted on the axis of the drum,
of two pawls depending from the lever and engaging with said rack the said pawls
being adapted to be operated by the rack and to operate the lever a definite
amount in opposite directions and of a means for transmitting one of the motions of
the said lever to the drum substantially as described.
3. In cash tills in which a band of paper within the till is automatically traversed
under a slot opening in the lid of the till every time the till drawer is opened and
closed, the arrangement of the pawls determining the motion of the drum on which
the said paper band is wound substantially as described and so that they can
readily be put out of gear to enable the drum to be manipulated by hand when
changing the said band or otherwise.
4. The improvements in cash tills substantially as described with reference to
the drawings.
