4, WALTER THOMSON, of Melrose House, Whitley, in the County of
Northumberland, (rocer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a new or improved cash registering till and is intended
to check the amount of cash paid into a cash box.
To effect this purpose in a simple manner I propose to use slide drawers
corresponding to pounds shillings and pence or parts thereof.
Each slide drawer may be provided with a sufficient number of hinged pauls
arranged in rows behind each other so that the drawing out for example of the
pence slide shall cause the paul or pauls each of which acts as a check on the
number of pounds shillings or pence as the case may be to actuate to the extent a
ratchet wheel arranged to gear therewith and turn it. This ratchet may actuate a
wheel on the same axle which in turn may gear with another similar wheel on
another axle the latter or its equivalent also carry ing a single-toothed wheel adapted
to actuate to the requisite extent at the required moment the ratchet corresponding
to the shilling slide.
The latter ratchet similarly actuates a wheel on its axle which gears with a
wheel on an axle on which may be another single-toothed wheel or disc which in
turn is designed to actuate to the requisite extent at the requisite moment the
ratchet corresponding to the pounds slide and in like manner any required number
of wheels and ratchets and pauls and axles may be arranged or geared together to
register the amounts of pounds shillings and pence as above that are or may or
ought to be paid into the cash box.
Each slide is further connected to the cash drawer or drawers by a simple stop
catch or locking device of any suitable description so that the drawer cannot be
opened until a slide is first operated and the closing of the money drawer by the
like device also closes the slide.
The operation of the slide rotates a ratchet an amount proportionate to its
opening and this action allows the cash drawer to be opened.
On each slide or connected therewith is a rack adapted to gear with a pinion or
wheel which in turn may actuate a registering dial or wheel or system of such
which is intended to show the customer the amount he may have paid.
Any one or more of the slides may be operated singly or together as may be
desired.
The whole may be mounted in a box or casing of suitable shape, and ornamented
as desired.

page_text: 1, WALTER THOмson of Melrose House, Whitley in the County of
Northumberland, Grocer, 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 a new or improved cash registering till and is intended
to check the amount of ensh paid into a cash box.
To effect my purpose 1 employ a system or combination of springs stops slide-
stop-racks toothed wheels ratchets pauls axles locking and unlocking adding and
registering devices arranged and combined as bereinafter described and in order
to fully explain my invention I will now refer to the accompanying drawings in
which
Figure 1 shows a part plan view of the whole apparatus ;
Figure 2 is a plan view as hereinafter described with the casing key board and
indicating wheels removed;
Figure 3 is a sectional elevation showing cash drawer shut and
Figure 4 is a part. similar view showing cash drawer open and in the following
description like marks of reference designate like parts.
Referring to the drawings, 6 is the key board. The keys 6 are intended to be
pressed down in opposition to the pressure of certain springs surrounding the
spindle of each key. The lower end of the key when pressed down projects below
the key board as shown in Figure 4 and acts as a stop to stop bars 10 hereinafter
mentioned. In the key board there are shots 7 up through which handles 8 project.
These handles are attached to racks 9 which are thus adapted to slide to and fro
as required on guide bars 10.
There will be a separate rack and handle and set of stop keys and stop bars for
pence, shillings and pounds or if desired for parts of them." Each rack 9 has a
striking bar 10 on it designed to engage with the lower end of one of the key
spindles 6. Each rack further engages a toothed wheel 11 a barrel 12 on one side
of which gears by chain 13 or otherwise as desired with an indicating wheel 14
and on the opposite side of the wheel 11 a paul 15 gears with a ratchet wheel 16 to
turn, when the rack is being drawn forward or outwards, a wheel 17 which gears
with a wheel 18 on another axle on which are also mounted pauls 19 which gear
once in a revolution with and actuate at the requisite moment eg. through the
tripping levers 20 aud pauls 21, the next toothed wheel 22 of the next series of
wheels forming the adding mechanism.
Only when a rock is drawn forward is the adding mechanism in operation; when
the racks are pushed back: the ratchet 23 in each case is held by spring paul 24 to
prevent the adding wheels from turning.
The return motion of the rack of course returns the indicating wheels 14 to their
original zero, the pauls 15 now slipping over the teeth of the ratchets 16 without
moving them. At the side of each wheel 17 of the adding mechanism is a
barrel 25 on which are recorded pounds shillings and pence as on the indicating
wheels 14 above described.
In the drawings (Figures 1 and 2) only two sets of keys and racks and gear
corresponding for example to pence and shillings are shown as the mechanism for
pounds is merely a repetition of the same or equivalent mechanism and it will be
understood that a third set of keys, racks and gear are required in order to
complete a pounds, shillings and pence registering till.
In the cash drawer 50 there is mounted a cross bar 51 as shown and on this bar
the locking levers 52 are hinged. The frame 53 serves as a central support for
the bar 51 as well as to uphold the longer ends of the levers 52 in the bearing at 54.

page_text: The levers 52 are hooked at 55 as shown to engage the fixed catch pieces 56 and
their opposite ends 57 are formed so that when a rack is drawn forward or
outwards, the stop bar 10 thereon strikes and depresses the ends 57 and lifts the
ends 55 out of the catch pieces to unlock the drawer and when the drawer is again
closing the hooked ends slide up the inclined portion of the catch pieces and then
fall into their recesses to lock the drawer.
In the cash drawer there are further mounted on the cross bar 51 the rack- or
slide-returning levers 58 as shown. When the drawer is closed the longer and
heavier ends of these levers are held up on a striking plate 59 so as to slightly
depress their shorter arms below or about the level of the rack stop bars 10°.
When the drawer is opened, these levers 58 drop against a stop 60 and their shorter
arms are then above the level of the bars 10 so that when the drawer is being
closed the extremities of the shorter arms of these levers strike the bars 10 and
push the racks back to zero and when the drawer is closed they assume the position
shown in Figure 3. Figure 2 indicates in dot-and-pick lines the positions of
levers 52 and 58 when cash drawer is open.
The cash drawer itself may be caused to open automatically if desired, when
the locking mechanism is released as above described, by providing springs 26 at
each side thereof, the closing of the drawer compressing the springs to store up
energy sufficient to push open the drawer when unlocked.
The operation of the improved cash registering till is as follows:-
Suppose a customer buys an article costing seven shillings and nine pence: The
attendant first presses down the shillings' key marked 7 and then draws out the
shillings' rack which necessarily stops opposite 7: he also presses down the pence
key marked 9 and then draws out the pence rack which necessarily stops opposite 9.
By the gearing described the transaction will be shown through the windows W on
the wheels 14 and it will also be registered privately on the barrels 25.
If the next customer spends thirteen shillings and four pence, the attendant
will operate the keys and racks in manner just described, but in this case the
adding mechanism will come into operation and by the gear described the pence
barrel 25 will then indicate !, the shillings' barrel and the pounds' barrel 1 or
£ 1s. Id. while the actual transaction of thirteen shillings and four pence will be
shown at W as above described It will of course be observed that the drawing
out of any rack by any handle 8 causes bar 10° to depress 57 and elevate 55 to
unlock the drawer, the racks being returned by the short ends of levers 58 striking
and carrying with them bars 10 in closing the drawer the locking of which takes
place as already described.
At the close of a day's working, the total amount in the till should correspond
with the amount recorded on the barrels 25, thus checking the action of the
attendant at the machine.
If desired a bell B may be caused to ring by a stop 70 on the drawer operating
the striker 71 each time the drawer is opened.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I claim no general principle as applied to cash registering tills because I am
aware that mechanical cash registering tills per se are not new but what I do
claim is -
1. In a cash registering till the arrangement or combination of keys 6 racks 9
with striking bars 10 and handles 8 locking and unlocking levers 52 with catch
pieces 56 and rack- or slide-returning levers 58 with plates 59 al arranged
combined or adapted to work substantially as and for the purposes set forth.
2. In a cash registering till the combination with an arrangement such as is
referred to in the preceding claim of the wheels 11 with barrels 12 gearing with
indicating wheels 14 and with pauls 15 gearing as required with adding mechanism
consisting of ratchets 16 wheels 17 and 18 check-ratchets 23 recording drums 25

page_text: pauls 19 tripping lovers 20 and pauls 21 all these parts being arranged combined or
adapted to work substantially in the manner and for the purposes; herein set forth.
3. In a cash registering till the arrangement or combination of keys G
handles 8 racks 9 striking bars 10 levers 52 and 58 with catch pieces 56 and
plates 59 and wheel aystem gearing with the racks 9 all arranged disposed combined
or adapted for use substantially as and for the purposes herein described and
illustrated in the drawings annexed.
Dated this 19th day of April 1895.
