I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitore, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancastor, 118, New Street, Birmingham in the
County of Warwick and 322, High Holborn in the County of Middlesex, Civil
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 cash registers, or check tills. The
particular machine shown in this connection is a machine having numbered keys.
actuating corresponding indicator tablets and operating a register mechanism in
connection with the money drawer, though certain of the improvements are adapted
to different styles of cash registers or check tills.
The objects of this invention are first to construct a cash register which is
absolutely perfect in registration; second, to simplify the mechanism and working
parts of a cash register; third, to make a cash register which shall contain few
parts and admit of perfect construction for perfect work at a greatly reduced cost
of manufacture; fourth, to construct a register which will not require close fitting
of parts to secure accuracy; fiftb, to provide a cash register in which it is.
impossible to over register or vary the registration to cause inaccuracies by noy
manipulation of the keys; sixth, to provide in a cash register means whereby after
a key completes its stroke it is entirely disengaged from the register mechanism ;.
seventh, to provide improved means of securing complete and accurate registration
of a number of indicator tablets struck up at the same time; eighth, to provide a
cash register in which there are different groups of keys and indicators corresponding
to the denominations of money so arranged that all will register in one complete
registering apparatus which will indicate the sum total at a glance without any
calculation; ninth, to provide an improved register mechanism consisting of trains
of geared number wheels so constructed that the gears can be operated independently
without actuating those lower in the scale and only operating those of a bigber order
when necessary; tenth, to provide an improved construction of register mechanism
for cash registers for carrying the registration from all parts of the machine to a
single registering device; eleventh, to provide an improved money drawer
mechanism for a cash register and further objects appearing definitely in the
detailed description.
The objects of this invention are accomplished by the devices and means
described in the following specification and illustrated in the accompanying drawing,

In the drawing all of the sectional views are taken looking in the direction of
the little arrows at the end of the section lines and similar letters of reference refer
to similar parts throughout the several views.
Referring to the lettered parts of the drawing, A, represents the base which
carries the drawer and to which the locking and actuating mechanism is attached
and on which are supported all of the remaining parts of the machine. A'represents
the general frame work of the machine which rests upon the base and carries the
register mechanism, the indicator tablets and the register keys which are suitably
encased by a casing indicated by the dotted lines in Fig. 4. On a shaft B,
extending through the front of the frame A', are the register keys B', which are
here shown in two banks and three groups. On the outer end of each key is a
suitably marked disk with a horizontal disk above for the application of pressure
for depressing the same. A common bar E, extends across all of the keys B', a
little to the rear of the shaft B, to assist in returning them all to the initial position
after a key or keys has been actuated. This is accomplished through connections
with the union key. The register keys B', project rearwardly through the
frame A, and on the rear end of each key is a downwardly projecting trailer
portion N.
Ou the back of this trailer portion N, is a suitable rack which is formed on the are
of a circle having for its center the center of the shaft B. Extending transversely
across ench section of the machine and to the rear of the frame is a bar K, pivoted
at each end so that it will rock back and forth. To au upwardly projecting ear
thereon is attached a coiled spring h, which extends upwardly and is attached to
the frame A'. This holds the bar in substantially a horizontal position and it acts
as a pawl on the racks to the back of the trailer N, and will act as a detent for any
key when passing in either direction uutil it reaches the end of its stroke, when
the trailer passes the bar and allows it to reverse and permits the key to move in

page_text: the opposite direction. This has the effect of compelling the complete operation
of any key in either direction until it has completed its stroke, and is a very simple
and effective means to that end. The bar K, is a common pawl to all of the keys
in a group.
The rear ends of the keys B', are guided between suitable upright bars B' to
the rear of the machine casing A'. Supported on each of these bars is a wedge
shaped piece P, which is pivoted at its lower end in the bar and retained at its
upper broad end by an outwardly projecting hook shaped lug P', (see Figs. 2
and 5) in a little fork formed at that end which limits their motion. The amount
of motion of each one of the wedge portions P, is limited to the thickness of one
of the keys. When any one of the keys is struck up it crowds the adjacent
wedges P, to each side in passing and by so doing moves the other wedges P, to
cach side and prevents their being returned until the key las completed its stroke
and returned to the initial position. The key and its trailor being between the
wedges when the key is operating prevents any other key from being actuated
because the wedges or key arresters as they are called cannot be moved to one side
and allow them to pass.
The movement of these key arresters is limited by the lug P, at the top. Each
division of keys for each division of the machine is provided with a set of these
key arresters. Between these key arrester bodies P, of each group of keys are
pivotally supported downwardly depending bodies R, R, for transferring the
motion from one division of key arresters to the next when any key of the machine
is operated thus making it impossible to operate more thau one key upon the
entire machine at once. These bodies R, R, are made large and are recessed out
to accommodate the intervening construction.
Above each register key Bi, are suitable indicator slides F, which are adapted
to move up and down in suitable guide ways. At the top of the slides F, are
supported the indicator tablets F. Below and to the rear of each indicator slide
is a catch F, facing downward. These indicator slides aro positioned to be raised
by the register keys corresponding thereto and there are suitable means of retaining
them in the elevated position which will be hereinafter described with the means
of releasing the same.
This machine is made up of three sections or divisions, first registering amounts
less than ten cents at a stroke, the second group indicating and registering units
from ten cents to ninety cents inclusive, and the third group registering dollars
from one to ten.
A transverse horizontal bar J', extends across the back of the indicator slides
of each outside group or division of the machine. A bar J, extends ncross the
backs of the indicator slides of the central division of the machine. These bars
are held in place by suitable upwardly projecting arms f, which are pivoted to a
frame A', above. A spring f' actuates each bar so that each swings positively
against the indicator slides of its group. Projecting inwardly from each bar J,
and lapping over the central bar J, and a little separated therefrom are pro-
jecting cars or arms J", which will be struck by the central bar J, where it is
pushed back and swings the outside bars .', as well. These bars J, J', are detent
bars and engage under the catches F", of the indicator slides and retain them in
the elevated position.
Across all three of the groups of keys extends a common bar E, which is pivoted
on the ends by suitable arms E, on the shaft B. The actuation of any key of any
group operates the bar E. The bar E, returns promptly to the initial position by
the force of gravity and by the action of the spring connected with the union key
hereinafter to be explained.
To one side of the machine is a key B", which is called the "union key." This
key is supported on the shaft B, and extends through to the rear of the machine
where it has a trailer below with a rack thereon similar to the register key. This
rack is acted upon by the reversible pawl K', which causes it to make a complete
stroke and also supports the same, after it is started and before it completes its

page_text: upward stroke. A hook portion r, extends from this union key over the common
bar E, so that when any register key is operated it actuates the union key at the
same time. Ou one side of the union key B, is a cam shaped lug a', clearly
appearing in Figs. 4 and 13. Pivoted to the frame A', is a lever I, which is
connected to a rock shaft I". On the lower end of the lever I, is a cam shaped
lug I', which is in position to be acted upon by the cam lug a', on the union key.
A suitable spring holds the lever I, in its normal unactuated position. An arm I¹¹¹,
projects upwardly from the inner end of the rock shaft I", in position to engage or
strike against one of the arms f, of the bar J. This arm 1, when actuated
strikes against the arm, and swings the bar J, to the rear which engages the
bars J, J, by the ears J, aud releases all the indicator slides. From the
description it will be seen that when the union key is in its unactuated position
that the operation of any register key will actuate the same and through its
connection throw the bars JJ, to the rear and release all the indicator slides
that may be up, and allow them to fall. The lug a', on the union key and the
lug I, on the lever 1, pass each other during this operation and the detaining
bars J, J, drop against the indicator slides to support any that may be struck up
at this operation. The striking up of any register key does not carry the union
key to its highest position. Until the union key reaches its highest position it will
be detained by the reversible pawl K, so that when it is desired a key of each
division can be operated without actuating the union key which will still remain
in the elevated position. When a key of each division has been operated the stroke
of the union key can be completed by merely touching it and the machine is ready
for another evolution or registration. The union key of course when it completes
its stroke returns promptly to its initial position by reversing the pawl K. Under
ordinary circumstances this operation of the union key is effected by the drawer
cover or drawer mechanism as will hereinafter appear. The union key however
cau be operated entirely independent of any of the other keys, at the end of or at
the beginning of each registration.
The money drawer U, of this improved cash register slides into and is supported
in the base A, of the machine. Fixed to the center of ench side of the drawer is
a suitable guide which slides into a horizontal grooved bearing toward each side
of the base, in the vertical pieces L. Suitable rollers k are on the pieces L, above
and below the guide pieces. There is a cover A" for the front portion of the
drawer which is carried on rollers i, i, which ride on the upper edges of the
pieces I, which form a track for the same. Projecting forwardly from the rear
of the base A, are rods l, which support coiled springs, which are attached to
downwardly projecting knobs or pins on the drawer cover A". On the underside
of the cover A", is the catch lever T, which is rounded on its front side and
adapted to engage in a hole upon the top of the base. The lever is held in the
engaging position by a suitable spring. When the drawer cover A", is pulled
forward the catcb lever T" engages the hole in the top of the base and holds the
cover in the closed position against the tension of the springs . A suitable
release mechanism hereinafter to be described actuated from the keys above
depresses this catch and allows the cover to opon when the machine is operated.
To the rear of the base A, pivoted to a suitable lug is a curved lever 'T', having
a hook formed on its under side to engage the hack of the drawer a id a stop
to support it in an operative position when the drawer is removed. The underside
of this lever curves upwardly and forwardly across the path of the rear edge of the
cover A". When the cover A", is released and opens it slides uuder lever 'T', and
raises it up and by so doing unhooks it from the drawer which can then be easily
drawn out. Thus the opening of the cover of the drawer unlocks the same so that
the entire drawer can be drawn forward. This construction of money drawer is
very advantageous in that the first compartments can be used for coins which are
most frequently required and the rear coinpartments for bills of larger denomination
which are less frequently required in making change.
When the drawer is closed and the cover A" drawn out, the whole is locked aud

page_text: no one can gain access to the money drawer without operating the register above.
The usual alarm bell T is provided and is actuated by any suitable projection on
the cover when it flies open, and also when it closes.
On a lug on the upper side of the baso A, is pivoted a lever Q, having a down-
wardly projecting end positioned to strike the upper end of the catch lever T".
The opposite end of this lever Q, is connected by a link, to the common bar E,
where it will be actuated every tinie the union key is actuated. As the bar E, is
actuated at the beginning of each registration, the lever Q, will be operated which
will depress the catch lever T", which will release the drawer cover below and
allow it to open, thus operating the register mechanism opens the drawer.
A bent lever O V, is pivoted beneath the union key and above the path of the
corer A, of the money drawer at O". The pivot O may be on the upper part
of the base A, or on the frame A' above. The arms of the lever project rearwardly
into the machine. There is a piu thereon for engaging underneath the union
key to support it in its highest position. The lower arm V. of the lever projects
downwardly and rearwardly across the path of the cover A". The lower end of
the arm V, is rounded so that the cover will pass under it freely in either direction.
When the cover is released by the operation of the register it slides under the
arm V, of the lever and raises the portion O, which carries the pin r, against the
union key and retains it in the elevated position so long as the drawer is open.
When the drawer is closed again it allows the lever O V, to fall and permits the
union keep to return to its initial position.
When it is desired not to actuate the union key from the drawer and its
mechanism the pin, is lowered to the hole r, in the arm O, of the lever which
will not carry the union key to the end of its stroke when it will be operated the
same as though no drawer was used in conuection.
The registering mechanism is actuated from goar wheels C', which are supported
on the shaft C, through the frame A', parallel with the shaft B, and above and to
the rear of the same. The registering mechanism for each section of the machine
is practically identical with the exception that units of a different order are
registered in each one. Arms M, M, are supported on suitable hubs which have
their bearings on the shaft or rod C. These arms M, M, stand at different angles
to the plane of the keys B', and at an angle to each other aud carry on their rear
ends a bar M, and towards the front of the machine a bar M", which bars are
transverse to the keys B', and above the same so that each key in striking the arm
will actuate the same a different amount varying for each key in proportion to the
sum marked upon the front of tlie key. A bar M", is located at such a height and
position that when the bar M', has reached the height to make a complete
registration it strikes the top of the key in a position to the front of the shaft C,
and serves as a perfect stop and prevents its being carried too far to register the
amount perfectly.
To the rear of each bar M', is an additional bar t, supported on little rollers !!!,
in longitudinal slots in the said bar t. A bar u, is back of the hart, to retain
and guide the same. On the underside of the bar t, are downwardiy projecting
cam shaped hook catches t', corresponding in number to the register keys B', of
the particular group of the machine.
To the right hand end of the bar M', is pivoted a dog S, positioned to engage
between the cogs of the gear wheel C'. The hart, is positioned to strike against
the dog S, and force it into engagement with the wheel C. As before stated there
is one of the downward projections i, to correspond with each key of the section.
Each key is positioned to strike under its appropriate cam portion t', in its
operation and carry the bar 1, towards the right and force the dog S, into engage
ment with gear wheel C. When the key is thrown up against the graduated
bar M', owing to the fact that the key and bar are supported on different centers
the bar slides over the key as it passes up. A projection u', shouldered on the under
side is formed on each key and engages the hook notch of the cam portion, which
will lock the graduated bar M', to the key so that they cannot be separated during

page_text: the operation of the same thus preventing the throwing of the graduated bar beyon
the actuating key.
Supported on the frame A', toward each end of each bar M', is a pawl e, held to
position by a suitable spring. On each end of the bar t, are rearwardly projecting
ears or lugs, which are in position to be engaged by the pawls c, and retained
there until the bar t, is carried to one side by the operation of one of the register
keys B. These pawls lock the register mechanism in its initial position so that it
When the
can only be actuated from one of the keys in its appropriate manner.
register key reaches the upper end of its stroke the engaging notch of the portion ',
slides off from the projecting portion u', on the side of the key so that when the
register key drous back the bar t, is released and forced back by the spring S', of
the dog 8, to its initial position. When the bar M', drops down it of course
carries the bar, with it. The pawls c, are forced back by the lugs or ears v' on
the bars t, which are then engaged by the pawls and the operation of the register
mechanism in any other way than by the register keys prevented, a pawl u, engaging
the gear wheel C, and prevents its return after it is actuated.
This means is shown modified in detail for locking the key and register mechanism
together during their operation in Figs. 10 and 11, which illustrate the structure
used on the lowest group of keys. In connection with the graduating bar at that
point is a pawl D', pivoted on the pivot a, adapted to engage between the cogs of
the gear wheel for that section. A portion D", extends across the section parallel
with the graduating bar in position to be actunted by any register key on the
upward stroke which will hold the pawl securely in nesh with the gear wheel
when the register key is actuated. A part el, extends across the section and cam
hook portions e, corresponding to the portions t', of the other sections in the
principal construction are on the under side. This part e' is pivotel at a, the same
as the part D'. The lugs u', on the keys swing the hooks to one side and become
engaged by them and lock the keys to the graduated bar through the remainder of
their stroke. This locks the key against the portion D", which retains the
pawl D', securely in mesh with the gear wheel C. When the key has completed
its stroke the book e, slides off from the lug u', on the key and allows the key to
separate from the bar which permits the pawl D' to disengage and allows the
graduated bar to return freely. A suitable stop, is provided to limit the down-
ward stroke of the graduated bar and support it above the key or keys to permit
a proper actuation of the same. It will be observed that the structure here
described is the same as the main structure with a modification of details.
The gear wheels C', have teeth on their peripheries which project outwardly
like a plain spur gear and also laterally to form bevel gears to actuate the adding
mechanism contained in the case H, above. The case H, is supported upon the
frame A', the adding or register mechanism is contained therein. This adding
mechanism consists of a train of number wheels beginning at the lowest denomina-
tion at s passing to the register wheel at j', passing to the register wheel m, to the
wheels to', and so on to the train indefinitely. These wheels are constructed on the
scale of one to ten that is ten revolutious of the lower wheel are required for one
revolution of the next higher. This machine is made to register ouly amounts of
five cents and upwards, consequently the lowest wheel is actuated an entire half
revolution on the stroke of the lowest key and has only the register figures five
and zero upon it as every second stroke is transferred to the next higher wheel.
Where the register is designed to register from one cent up this lowest wheel will
register from one to ten cents and there will be a one cent key, a two cent key,
and so on up to nine cents and the lowest wheel would be actuated these various
amounts by the different keys. A spur, cog or pawl is ou each wheel to engage in
suitable notches or gears on the next wheel above it to move it one step forward
on each revolution or as many steps for each revolution as there are spurs, cogs or
pawls provided. There are three divisions or sections to this machine and the
keys of each division actuate independently the three lower wheels of number
wheels. The division to the left is connected to actuate the number wheels,

page_text: corresponding thereto through its gear wheels C, meshing with the gear wheel G...
of that division which transmita its motion through the shaft G, through the.
bevel gear 1, s, to the shaft g, which actuates the number wheel s. The central
section netuates through its gear wheel C', the bevel gear on the shaft j, which
carries the number wheel j'. The right hand or dollar group actuates from its
gear wheel C, the gear G, which transmits its motion through the shaft G", to-
the beveled gear to, which meshes with the pinion w, on the shaft n, which
carries the number wheel m'. It is thus clear that each group of keys or division
of the machine actuates its appropriate number wheel in the train. As none of the
number wheels above the wheel m', are actuated except by the number wheels
below nothing special is required in their construction as only an ordinary train of
gear is necessary.
The wheels m, j, and a, are differently connected so that each wheel can be
actuated independently without actuating the gears below. On the unler side of
the wheel, an arm j, projects out and carries a spring pawl. The spring on..
this pawl holds it outwardly in the engaging position and it is formed to engag
the toothed wheel m", which carries the number wheel m', on its shaft one step at.
each revolution of the wheel j. A bar W, carrying a dog W, positioned to
engage between the teeth of the gear wheel m", extends across the underside of
the case H, and is adapted to reciprocate on two carrying screws at that point.
which pass through little slots in the same. A spring b, holds the dog' W.
normally out of engagement with the gear m". A lug y, on the shaft j, is
positioned to engage a lug y", on the bar W, when the pawl, actuntos the genr
wheel m". This throws the dog W', momentarily into engagements with the gear
wheels m, and prevents over registration when the wheel w", is actuated from
the wheel. This structure appears very clearly in Figs. 17, and 15. In Fig. 17
a portion of the gear y, is broken away to allow the lug y', to appear.
The pawl is pivoted to swing in the direction of the notion of the
wheels m, m, and allows them to be actuated in that direction without actuating
the lower wheel j'.
As the number wheels, carries but one tube and rotates half way round at each
stroke of the key no such construction is necessary to connect the same to tho-
number wheel. A locking lever g, is pivoted at g, between the wheels s,
and, to engage and lock the gear wheel j, as soon as it has been actunted oue-
step, by the piu g', striking against the same and throwing it against the teeth of
the gear wheel. The pin gl, passes the end of the lever at the end of the stroke
and so permits the free motion of the wheel j', independent of the wheel s, excopt
when the wheel &, is being operated. It is thus clear that ench division of the
machino will actunte the register mechanism exactly in proportion to the amount.
of a key struck up in a division. The key arresters and the common reversible
pawl neting upon the trailere of all the keys to the rear of the machine compels the
complete operation of any single key started before another key can be operated..
The dividing of the sustaining bar for the indicator slides into lengths corre
sponding to the divisions of the machine as hero shown and arranged permits an
indicator to be raised and supported in each division of the machine for each.
registration. This permits a registration in which an indicator slide can be
supported in each division and secures complete registration of all amounts
indicated.
Having thus described in detail and specifically tho entire cash register, my
correspondents desire to state that it can be greatly varied in its details without.
departing from the invention.
This is especially true of the improved drawer mechanism, and of the improved
graduated bar nechanism and its connected devices and of the uuion key feature
and of the special means of supporting and operating the indientor tablets and the
special locking mechanism for the registering wheels. It will be readily under-
siced ibat there is a great variety of catches that can be substituted for the
catch T", of the drawer cover. Other specific means can be easily devised from.

page_text: what has been shown for locking the keys to the graduated bar. The uniou key
can he attached to the common bar by various means. The tripping mechanism
for the indicator slide can be used with a great variety of detaining devices for
that purpose and there are various other and numerous changes which will
readily suggest themselves to those skilled in the art to which this invention
pertains.
