page_text: I, BENJAMIN THOMPSON O'BRIEN, of Slater Street, Liverpool, in the County of
Lancaster, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the construction and arrangement
of check tills in which the drawer is closed by the operation of springs and also
wherein a coin exhibiting device is moved to and fro by the opening and closing
of the drawer.
On the bottom of the reciprocating drawer I place one, two or more inclined
planes or cam surfaces against which runners operated by springs travel as the
drawer is moved to and fro. These are straight or parallel for the greater part
of their length and diverge at or near one end so that the action or pressure of the
runners along the straight or parallel part is at right angles to the longitudinal
axis of the drawer and has no effect in moving it while at the ends the pressure
is capable of exerting an effect in the direction of the axis and so of moving the
drawer to close it.
On the bottom of the till box or case is fitted to pivoted levers of straight ☐ or
other convenient shape and at the free end of each is fitted a runner which, when
in position, engages with the inclined or cam surfaces on the bottom of the drawer.
To each lever is attached a spring or springs. A casing of T or other shape is
affixed to the bottom of the till or case to one end of which the levers are pivoted
and to the other end the springs are attached.
The receipts of cash are entered upon a travelling band of paper which is wound
upon a drum which is rotated part of a revolution each time the drawer is opened
by a lever with a pawl at one end engaging with a ratchet wheel the lever being
operated by an incline or cam on one side of the drawer.
Above the drawer or in other convenient position is placed a tray with a glass
cover on to which the coins are delivered or deposited through a slot. This tray
is preferably grooved and provided with depending plates or fingers to prevent
the coins travelling in the wrong direction. The tray or the depending plates
or fingers is caused to reciprocate on the opening and closing of the drawer to
cause the coins to travel forward. This movement is effected by another inclined
surface on one side or top of the drawer operating a lever or connecting rod
connected thereto.
The slot through which the coin is admitted to the exhibitor is provided with
a lid or cover on the under side by which it is closed when the drawer is shut and
opened when the drawer is open to prevent the entrance, of coins without open-
ing the drawer and moving forward the papers. This lid or cover is pivoted and
a double ended lever or other similar device is provided for opening and closing
it. And on the reciprocating slide of the coin exhibitor is a projection, which
engages with the said lever. When the slide is moved in one direction the pro-

page_text: jection passes under an incline in one end. which moves the cover on its pivots and
opens or uncovers the slot and when the slide is moved back the projection operates.
upon the other end of the lever and moves the cover back and closes the slot and
continues to lock it or hold the slot closed whilst the drawer is closed.

Improvements in Casn · 11s.
I, BENJAMIN THOMPSON O'BRIEN, of Slater Street, Liverpool, in the County of
"Lancaster, Mechanical 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 following statement:-
This invention relates to improvements in the construction and arrangement
of check tills in which the drawer is closed by the operation of springs and also
wherein a coin exhibiting device is moved to and fro by the opening and closing
of the drawer.
The improvements will be fully described with, reference to the accompanying
drawings:

with drawer closed.

1.
Fig. 4. Longitudinal section of part of the till showing position of coin exhibitor
when the drawer is open.
Fig. 5. Plan of parts of coin exhibitor.
The till case A is of any ordinary construction of wood, metal, or the like in
which is enclosed a money drawer B also of any ordinary shape or construction and
of suitable material such as wood, or metal.
To the bottom of the money drawer B preferably. in a recess C cut or formed
therein are fitted the two inclined planes or cam surfaces D against which run-
ners E travel as the drawer B is moved to and fro.
The cam surfaces D) are made straight and parallel for the greater part of their
length and are inclined or diverge at or near the front end so that the action or
pressure of the runners E along the straight or parallel part is at right angles to
the longitudinal axis of the drawer B3 and has no effect in moving it while at the
ends the pressure of the runners E is exerted in the direction of the longitudinal
axis of the drawer and so moves the drawer to close it.
On the bottom of the till case A below the drawer B is secured a bracket F
to which are pivoted a pair of levers G carrying at their free ends the runners E.
The levers G may be straight or of L or other convenient shape and to each is
attached a spiral or other spring H the force of which is exerted to draw or force
the levers outward and backward. The bracket F to which the levers G are
pivoted at one end is preferably of T. shape and secured to the bottom a of the
till case A to the other end of this bracket the springs H are attached. The
levers G and the springs H may be secured direct to the bottom of the till case
prefer the arrangement shown as it relieves the screws of the pressure and
force exerted by the springs.
but
In another modification the cam surfaces or inclined planes may be attached to

page_text: the bottom a of the till case A and the levers G and springs H to the bottom of
the drawer but at present. I consider the arrangement shown preferable...
The amounts of cash received are entered or recorded upon a travelling band of
paper K which is wound upon a drum L rotated part of a revolution each time
the drawer B is opened by a lever with a pawl M at one end. engaging with a
ratchet wheel on the end of the drum L the lever being operated by an incline
or cam on one side of the money drawer B.
.5
Above the money drawer B or in other convenient position is placed a tray N
with a glass cover n on to which the coins are delivered or deposited through, à
slot O. The tray N is preferably grooved and provided with depending plates or
fingers 'n to prevent the coin's travelling in the wrong direction. The tray N
(or the depending plates or fingers) is caused to reciprocate on the opening and
closing of the drawer to cause the coins to travel forward. This movement is
effected by another inclined surface P on one side or top of the drawer operating
a lever por connecting rod connected thereto. The opening of the drawer causes
the tray to travel forward to pass the coins inward and the closing of the drawer
draws it back the coins being prevented moving back by the fingers ni
The slot O through which the coin is admitted to the tray or coin exhibitor N is
provided with a lid or cover S on the under side by which it is closed when the
money drawer B is shut and opened as the drawer B is open to prevent the
entrance of coins without opening the money drawer and moving forward the
band of paper K. The lid or cover S of the slot O is pivoted and a double ended
lever s or other similar device is attached to one end to open and close it.
On the reciprocating slide or tray N of the coin exhibitor is fitted a projection T
which engages with the lever s of the cover S. When the slide or tray N is
moved forward by the opening of the money drawer B the projecting piece T
passes under the inclined end of the lever s and tilts or swivels the lid or cover S
upon its pivots uncovering or opening the slot 0 for the reception of coin and
when the slide or tray N is moved backwards again by the closing of the money
drawer B the projecting piece T engages the other end of the lever's and tilts
or swivels the lid or cover S back in the reverse direction closing the slot
continues to lock or hold the slot O closed whilst the money drawer B remains
closed. If desired the projecting piece T may be placed direct upon the top or
edge of the money drawer B to operate the oscillating cover or lid S of the money
slot 0. Thus no money can be inserted into any part of the till without first
opening the money drawer and thereby moving forward the recording band of
paper K.
and
The object of the coin exhibitor with reciprocating tray N is to receive coins
which while out of reach of either the payer or payee can be viewed through the
glass plate n to prevent disputes as to the denomination or value of the coin
before being deposited in the money drawer B. To prevent the coins as they are
inserted through the slot O being projected too far forwards and mixing with coins
that have been inserted or deposited at a previous transaction I provide stops U
which when the slot is uncovered engage with and lock the first set of depending
fingers or plates n which then act to stop or impede the movement of coins as
they are inserted. The stops U comprise a number of fingers a projecting through
openings in the tray N and moving backwards and forwards with it. These are
carried by a transverse bar with a crank or lever at one end which traverses
or rides over a plate V raised or inclined at one end. When the crank lever
traverses the raised part of the plate V the ends of the fingers u are projected
through the tray N in front of the fingers or plates n' and prevent them moving
by the weight or pressure of any coins behind them as shown in Fig. 4. The
fingers u are drawn back again by a weight W or by a spring.
Instead of the stops U working from below through the tray N they may be
placed above the fingers or plates n¹ and bend downwards to engage with them
in which case they will be operated by a projecting piece similar to T and in a
manner similar to that in which the slot cover or lid S is operated.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In a cash till the construction and arrangement of spring operated levers and
cam surfaces attached to or operating upon the bottom of the money drawer to
close it automatically when partially open substantially as described.
2. In a check cash till the combination with a coin exhibiting device of an oscil-
lating lid or cover for the money slot operated by a sliding projecting piece on
the exhibitor or on the money drawer which closes the money slot when the drawer
is closed to prevent the insertion of coins. without first moving forward the record-
ing band of paper substantially as described.
3. In a check cash till the combination with a coin exhibiting device of a stop or
locking mechanism for the depending plates or fingers to prevent the coins passing
too far as they are deposited therein substantially as described.
4. A check cash till having the several parts constructed and arranged in com-
bination substantially as described and shown.
