IMPROVEMENTS IN CASH REGISTERS AND INDICATORS
Year: 1885

page_text: I, HERBERT JOHN HADDAN, of 67, Strand in the City of Westminster, Civil
Engineer, do hereby declare the nature of my invention for IMPROVEMENTS IN CASH
REGISTERS AND INDICATORS, a communication to me from abroad by Clinton
H Maltby, of Dayton, State of Ohio, United States of America, Manufacturer, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
-
The invention relates to an improvement in cash registers and indicators designed
for the use of storekeepers and others as a means of accurately registering the
total cash receipts for any given period of time as a day, for instance, and for
indicating to the customers that the amount paid has been registered by disclosing
to their view such amounts upon figured tablets
'The present invention has for its most important object the provision of means
whereby a single complete revolution of each of the disk shafts will cause the
simultaneous resetting of all of the disks upon such shaft so as to bring all of their
zero marks under the reading apertures, which resetting can be done instantly
without expenditure of labour and loss of time
The novelty consists in the construction, arrangement and combinations of the
various parts as will be herewith set forth and specifically claimed.

figures
I provide any suitable box or cabinet A, ornamented as desired and of the
general shape indicated, though the shape and ornamentation may be varied
infinitely, having coincident glass covered apertures B through its upper ends for
disclosing to view the projected tablets, also having a hinged lid or door C upon
opening which the registering mechanism is disclosed, and having preferably at its
lower end, a drawer compartment in which is a drawer or till D
In this cabinet or case is fitted a metal frame work consisting chiefly of two
upright sides E E united by cross bars and by the shafts and bars which support
the operating mechanism Upon a transverse shaft or bar F in the lower front
part of the machine are hung or pivoted a series of parallel keys G which may be
of the shape shown in Fig 4 and each key has upon its front end, which extends
through and projects from an opening in the front of the case, a button H upon
which is marked a figure or number to correspond with the value intended to
be indicated and registered whenever that key is operated by depressing the
button
The rear ends of the keys rest upon a bar I at the rear side of the machine and
extend through the slots in a vertically slotted guide plate J, Fig 3, by which
means they are supported, held from lateral displacement and guided at their real
ends The plate J has its upper end bent at right angles so as to extend in a
horizontal plane, and through this bent portion, J1, are a row of apertures to permit
the passage of a series of vertical rods K, preferably square in cross section to
prevent their turning in their correspondingly shaped guide orifices in the
plate J
The lower ends of these rods K rest upon the rear ends of the keys G-one upon
each key and at their upper ends they are further guided by a transverse per-
forated horizontal plate or bar L, Fig 3 Upon each rod, K, just above the guide
plate J is a swell or shoulder M between which and the bar L, and encompassing
each rod, is a spiral spring N To the upper end of each rod is suitably secured a
thin, flat tablet, O, which has upon both of its faces a figure or number corre-
sponding with that upon the button of the key upon which said rod rests and by
which it is operated
Pivoted upon the shaft F on each side of the machine are two arms, P P, which
extend forward and are connected at their front ends by a transverse bar R which
rests just under the forward ends of the keys, as seen in Fig 1 One of these
arms P, preferably the one on the left side of the machine, has an upward
extension S beyond its pivotal point, as shown Flat springs T on each side
under the arms Pand transverse bar R serve to hold the keys up at their front ends
and to replace the same when operated Pivoted at U just in rear of the tablet
rods is a horizontal wing V from one end of which extends upwardly an arm, W
whose upper end is slotted at X, Fig 3
Pivoted at a to the upper left hand side of the frame is a pendant curved
hammer b lying adjacent to the arm W and with a lateral stud c entering the slot X
This hammer is arranged to strike a gong or bell Y suitably secured to the frame
Projecting laterally from the hammer is a lug & with its under side rounded or
bevelled, as seen in Fig 1 A flat spring e attached to the frame and bearing
against the lug & serves to hold the arm W and wing V in a substantially vertical
position, and to cause the hammer to strike the gong whenever any of the keys
are operated as will be hereafter explained Pivoted at f is a vertical arm or
lever 9 carrying at its upper end a pivoted gravitating tripping dog h which bears
against the lug d
d
Connecting the lower end of the arm g and the upper end of the arm S is a
link
From this construction it will be seen that whenever any key is operated by
pressing its button the arms P are forced down, the arm S thrown forward, thereby
oscillating the leverf whose tripping dog h presses back the hammer b which in

page_text: turn oscillates the wing V and throws it sufficiently far back to permit the upward,
passage of the shoulder M upon the ascending tablet rod, whereupon the adjustment
of the parts is such that the tripping dog holds its engagement with the lug d
until the key has been depressed to its furthest limit, the shoulder M raised above
the wing V and the tablet exposed to view through the apertures B of the case, at
which time, when the key has reached its furthest limit of depression, the tripping
dog slips past the lug d and fiees the spring e which, recoiling, causes the
hammer to strike the bell and reset the wing V in a vertical position so as to
receive and retain the shoulder M and thereby hold up the tablet in its exposed
position until, another key being operated, the wing is again oscillated or thrown
back to permit the passage upward of the other shoulder M and consequently
releasing the shoulder M of the before operated tablet rods which, by the action of
the spring N, aided by its own gravity, drops back to its normal position.
Pivoted, as at 1, about the centre of the bottom of the case is an arm k whose
front end extends under the bar R and whose rear end carries a bolt 7 which, passing
through the bottom or division m of the case, engages with the rear inner side of
the drawer to lock the same as seen in Fig 1
A flat spring n bearing upon the under side of the forward end of the bar k
serves to hold the bolt 2 down
The under side of the bolt is bevelled as shown, with a corresponding bevel
upon the edge of the rear side of the drawer over which the bolt slips, so that in
closing the drawer the bolt will be raised by the drawer in its passage until its
reir side has passed beyond the bolt, when the same is freed and is forced down,
to effect a lock, as will be readily understood Fastened to the rear side of the
case just behind the drawer is any suitable spring o, a plan of which is shown by
the dotted lines to the light of Fig 2 This spring bears against the rear side of
the drawer and whenever a key is operated to its furthest limit the bar R pressing
upon the bolt bar k raises the bolt Z until the key having reached its furthest
limit of depression the drawer is freed and the spring o propels the same partially
out of the case
To release the drawer it is only necessary to push it in until the bolt re-engages
Journalled in the fiame of the machine or, as in this instance, in a supplemental
frame C secured to the main frame, are two parallel horizontal transverse shafts A'
upon which are strung the independently revolving abutting registering disks B¹
The spur p, Fig 5, is in line with the spurs of the disks in the bank above so
that every time a disk of the lower bank makes one complete revolution its spur p
engages with one of the spurs of the coincident disk in the upper bank and turns
the upper disk one notch Upon the transverse shafts C₁ are secured brake
springs, shown by the dotted lines in Fig 1 which prevent the disks from
turning further than one notch at a time when the keys are operated
Pivoted to each key, as at 8, is an upwardly extending dog i which engages with
the spurs of the disk directly over such key, as seen in Fig 1 A spring u serves
to support and hold in proper working position the dogs t and the adjustment is
such that every time any Ley is operated to its furthest limit its registering disk is
revolved one notch The return of the key to its normal position draws back the
dogt for a fresh engagement As seen in Figs 5, 7, 8 and 9 the shafts A¹ have a
longitudinal slot v extending from end to end with equi-distant enlargements or
bores win the walls thereof In these slots are a series of abutting staple shaped
dogs D¹ which are projected by spiral springs E¹ confined in the bores w and
between the lugs of the dogs as seen particularly in Fig 9 There is one of these
dogs for each of the disks and they are so arranged as to be entirely independent
in action and to only engage with their respective disks
Their upper edges are slightly beveled so that when the disks revolve upon the
shafts in the direction indicated by the arrow in Fig 5 no engagement of the dogs
18 effected
The Journal or bearing of each disk, however, has a slight shoulder or notch y
which, when the shaft is revolved in the direction indicated by the arrow in Fig ɔ̃

page_text: enables the dogs to become locked with the disks and rotate the same From this
it will be seen that, while during the operation of the keys the shafts A¹ are
locked stationary by means to be presently described, the disks turn freely on the
shafts without engaging the dogs, but when it is desired to reset the disks of either
or both shafts to the zero or starting point a single complete revolution of the
shafts in the proper direction will engage and pick up the disks during their
revolutions, until their shoulders or notches are all in line and then carry the same
all together to such a point as brings the zero marks under the reading apertures
as seen in the upper bank of Fig 2
To hold the shafts locked I secure upon then outer right hand ends disks F
leaving the square ends Q¹ of the shafts projecting beyond the disks F¹ sufficiently
to be grasped by a wrench or key Each of the disks F¹ has a notch with which
the end of a pivoted gravitating locking dog H¹ engages as seen by the dotted
lines in Fig 1 The adjustment of the parts is such that, whenever either of the
dogs H¹ is raised and its shaft A¹ turned in the proper direction one complete
revolution until the dog re-enters the notch and relocks the shaft, the disks upon
such shaft will have all been brought with their zero marks exposed through the
reading apertures
Instead of the recessed staple shaped dogs D¹ I may employ as an equivalent
the construction represented in Fig 6 where, pivoted in a recess in the side of each
disk so as not to interfere with the next abutting disk, is a pivoted spring dog a'
which engages with a shoulder or notch in the shaft A' and by which the same
mode of operation and result in resetting the disks would be accomplished as will
be easily comprehended 1¹ I¹ are the index wings arranged over each bank of
disks and with apertures extending in straight lines across the machine through
which but a single number upon each disk can be read
The manner of keeping the register is as follows The machine illustrated has
eleven keys numbered in a progressive series 5, 10, 15, up to 55 The key marked 5
is the five cent key, the key marked 10 is the ten cent key, and so on The
registering disks of the lower bank which are operated directly by the keys have
upon them numbers from 0 to 29 inclusive, in a progressive series of 0, 1, 2, 3, &
The disks of the upper bank have a corresponding number of figures but in a
series which are multiples of 30, as 0, 30, 60, 90 and so on Upon the index wings
Just over the reading apertures are numbers to correspond with the numbers upon
then coincident keys as seen in Fig 2
Now the manner of ascertaining the cash taken in at the end of a days work,
or at any time, may be illustrated by reference to Fig 2, where it is shown that
the five cent key has been operated twenty nine times, the ten cent key nine
times, the fifteen cent key once, and the twenty cent key three times, and so on
across the bank In this illustration none of the disks in the upper bank have
been moved from their 0 points because none of the disks of the lower bank have
as yet made a complete revolution Supposing, however, that the five cent key be
now operated its 0 mark would be brought under the reading opening, its spur ?
would have turned the disk in the upper bank one notch, and 30 would be exposed
under the reading opening of the upper bank, and so on as will be readily
understood A third or a fourth bank of disks might be added if necessary The
cabinet is of course kept locked by the proprietor who alone can inspect the
machine to take off the readings and reset it
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1st In a registering and indicating machine having a series of figured disks in
one or more banks, the combination with each bank of disks of its shaft with
ratchet and pawl connections or their equivalents whereby the disks are free to
revolve upon the shaft in one direction without disturbing the same, and whereby,
upon revolving the shaft in another direction, the disks become locked thereto and

page_text: are carried around therewith to enable them to be reset at any desired point by a
single complete revolution of the shaft
2nd In a registering and indicating machine the combination with the registering
disks in one or more banks of the shaft A¹ for each bank, with ratchet and pawl
connections or their equivalents, the notched disk F¹ and locking dog H¹, as set
forth
3rd The vertical tablet rods K arranged in guides and provided with shoulders M
and encompassing spiral springs N in combination with keys G and wing V
substantially as described
4th The combination and arrangement of the wing V, slotted arm W, hammer b,
trip lever g, link 2, arm 8 and vibrating frame PR with the operating keys G
and tablet rods K substantially as and for the purpose specined
