Improvements in Cash Tills.
We GEORGE RODENHURST STOKES, Managing Director, of Brunswick House,
Hanley, and THOMAS MILNES FAVELL, Engineer, of Wolstanton, both in
the County of Staffs, do hereby declare the nature of this invention to be as
follows:-
This invention for improvements in cash tills relates to improvements on our
patent till No. 7634 of 1894 in which a band of paper within the till was traversed
automatically one step under a slot or opening in the lid every time an opening and
closing movement was applied to the till draw so that a fresh portion of the band
was brought under the opening in the lid to receive the record of the cash trans-
action. In this arrangement the band was traversed towards the front of the till so
that the record of the cash transactions were read from the bottom towards the top.
In order to obviate this defect so that the transactions may be read from the top
downwards, instead of causing the pawl to operate the front drum on the axis of
which it is pivoted it is caused to actuate the back drun which thus draws the
band from the front drum. The rack teeth are also formed as a series of curved
undulations.
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 front drum from which the
paper is to be unwound 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 are in the path of a series of undulations
formed on the top edge of a side of the till drawer the undulations being cut so
deep that when the pawls are vertical they do not extend quite to the bottom of
the undulations. It will readily be seen that when the drawer is moved in one
direction the undulations simply rotate one pawl on its pivot but the first undula-
tion 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 undulation is free to pass the pawl and that on the continued motion of the
drawer in the same direction the succeeding undulations pass the pawl without
further operating the lever. On moving the drawer in the opposite direction the
lever is inoved in the opposite direction in a similar manner through the other
pawl. Thus for each opening and closing movement the lever makes a definite
backward and forward motion and this motion is transmitted by means of a pawl
to a ratchet wheel on a back drum on which the band is to be wound.
Means are provided for operating a bell as the till drawer is opened and for
throwing the pawl out of gear when desired to manipulate the band.

We GEORGE RODENHURST STOKES, Managing Director, of Brunswick House,
Hanley, and THOMAS MILNES FAVELL, Engineer, of Wolstanton, both in the
County of Staffs, 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 improvements on our
patent till No. 7634 of 1894 in which a band of paper within the till was traversed
automatically one step under a slot or opening in the lid every time an opening and
closing movement was applied to the till drawer so that a fresh portion of the band
was brought under the opening in the lid to receive the record of the cash trans-
action. In this arrangement the band was traversed towards the front of the till
.so that the records of the cash transactions were read from the bottom towards the
top. In order to obviate this defect so that the transactions may be read from the
top downwards, instead of causing the pawl to operate a drum at the front on
the axis of which it is pivoted it is caused to actuate a drum at the back which
'thus draws the band from a roller in front. The rack teeth are also formed as a
'series of curved undulations.
In one arrangement of mechanism for operating the drum on which the band is
to be wound, a pawl lever is pivoted on an axis near the front 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
are in the path of a series of undulations formed on the top edge of a side of the
till drawer the undulations being cut so deep that when the pawls are vertical they
do not extend quite to the bottom of the undulations. It will readily be seen that
when the drawer is moved in one direction the undulations simply rotate one pawl
on its pivot but the first undulation 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 until the undulation is free to pass the pawl and that on the continued
motion of the drawer in the same direction the succeeding undulations pass the
pawl without further operating the lever. On moving the drawer in the opposite
direction the lever is moved in the opposite direction in a similar manner by means
of the other pawl. Thus for each opening and closing movement the lever
makes a definite backward and forward motion and this motion is transmitted by
means of a pawl to a ratchet wheel on a back drum on which the band is to be
wound.
Means are provided for operating a bell as the till drawer is opened and for
throwing the pawl out of gear when desired to manipulate the band.
In the accompanying sheet of illustrative drawings:
Fig. 1 is a sectional elevation of a till constructed according to this invention,
Fig. 2 is a cross section on line A A (Fig. 1) and
Fig. 3 is a plan the lid being supposed removed.
The band a passes from the roller 6 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 fis mounted loosely upon the pivot f' and two
pawls hi 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 drawings. The pawls gear in a series of undulations I formed on the
top edge of a side of the till drawer m, the undulations being cut so deep that when
the pawls are vertical they do not extend quite to the bottom of the undulations.
It will readily be seen that when the drawer is opened, the undulations / simply

page_text: Oscillate the pawli but the first of the undulations acting on the other pawl h
actuates the pawl lever fon its pivot f¹ until the undulation escapes the pawl, the
succeeding undulations passing the pawl without further operating the lever..
On closing the drawer the lever fis moved in the opposite direction by means of
the pawl. The movement of the lever fis transmitted to the long pawl n, formed
with a pawl end n¹ gearing with and actuating a ratchet wheel o on the end of the
drum d. A detent p pivoted at t and kept in gear by the spring prevents
any back motion of the drum when the pawl lever n and pawl end n' are
receding.
In order to leave the drum d perfectly free to facilitate the removal or manipula-
tion of an old band or the insertion of a fresh band a lever wo is so arranged that on
pulling it over, a pin u on its end acts upon the detent p and moves it out of gear-
with the ratchet wheel o. At the same time the pins upon the arm of the
detent P is raised and lifts the long pawl n in its guide n³, the pawl end n¹ being.
lifted out of engagement with the ratchet wheel o.
The detent p is also arranged to carry the hammer of the bell which is thus
struck once as the drawer is pulled outwards after being partially or completely
closed.
The end of the band is secured to the drum by means of a V or other-
similar spring v fitting in a longitudinal groove in the drum or by other suitable
means.
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 in which a band of paper within the till is traversed under a slot
or opening in the lid of the till every time the till drawer is opened and completely
or partially closed, the mechanism for operating the drum on which the paper is
wound in a forward direction so that the cash record can be read from the top.
downwards, consisting of undulatory teeth on the drawer, of a lever having two
pawls depending from it and engaging with the said undulatory teeth, the said.
pawls being adapted to be operated by the undulations and to operate the lever a
definite amount in opposite directions, and of a long guided pawl pivoted to the
lever for transmitting one of the motions of the said lever to the drum substantially
as described.
2. The improvements in cash tills substantially as described with reference to.
the drawings.
