Improvements in Cash Indicators and Registers.
I, MELVIN NEWTON LOVELL, of Eric, Pennsylvania, in the United States of
America, Manufacturer, 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:-
My invention consists in the improvements in cash indicators and registers
hereinafter set forth and explained and illustrated in the accompanying drawings,
in which,

Figure 5 is a transverse section of same on the line y y in Figure 2, looking in the
direction of the arrow.
Figure 6 is a detail view of the compound key lever mechanism of my machine.
Figure 7 is a rear view of the same in elevation.
Figures 8 and 9 are dotail views of portions of the same.
Like letters refer to like parts in all the figures.
In the construction shown of my improved cash indicator and register, the frame
consists of the sides A A connected by a plate B which rests upon and is secured to
a base B in which the cash drawer of the machine operates. On a rod A¹ in the
lower part of the sides A A of the frame are pivoted four groups of key levers, C, C¹,
Cand C, the group C representing cents from 1 to 9 inclusive; the group Ci
multiples of cents from 10 to 90 inclusive; the group C³ dollars from 1 to 9 inclusive;
and the group C multiples of dollars from 10 to 90 inclusive.
In the vertical grooves b, b, b, b, in the face of the frame plate B are vortically
sliding rack bars D' D2 D3 on which are feet d d d² and d³; the feet d resting
upon and being actuated by the group of key levers C; the foot d' resting upon and
being actuated by the group of key levers ; the foot d resting upon and being
actuated by the group of key levers C and the foot d³ resting upon and being
actuated by the group of key levers C³; each of said groups being adapted to operate
the foot resting thereon and the rack bar secured to such foot only. To the rack
bars D D D and 1) are secured racks a a¹ a² and a and c e' c² and e; the racks a a¹
a² a respectively intermeshing with and actuating pinions e e¹ and secured to
indicator wheels E E' E² and E³ respectively, said pinions and indicator wheels
being mounted on a rod F secured in bearings on the upper part of the frame
plate B.
The racks c ec2 and 3 also respectively intermesh with segmental gears G G¹ G²
and G on the rear ends of one of the arms of the bell crank lovers 9 g¹ g² and
which bell crank levers are mounted sleeves on the rod H, secured in bearings H¹
on the frame plate B.
On the rod H adjacent to the ends of the sleeves are also mounted gear or
ratchet wheels and each containing sixty teeth, or any multiple of tens of
teeth desirable.
On the outer ends of the arms i of the bell crank levers g g¹g² and g³ are pivoted
spring actuated dogs J J J and J adapted to engage with the teeth of the
wheels, and and actuate the same when the rack bars D D¹ D' and D³ are
respectively being raised by the operation of the key levers on the feet thereof, said

page_text: dogs, however, passing over the teeth in said wheels freely when said rack bars are
returning to their normal positions. In bearings K on the roar side of the frame
plate B nearly opposite the gear wheels, and, I mount short shafts k k¹ ª²
and 4, the shaft & extending from opposite the left hand side of the gear wheel / to
opposite the gear wheel, and the shaft from the gear wheel to the goar
wheel; the shaft from the gear wheel to the gear wheel; and the shaft
from the gear wheel to the gear wheel, as and for the purpose hereinafter
set forth. Secured to the left hand sides of the gear wheels, and aro six
carrying points equidistant from each other, one opposite each tenth tooth in said
gear wheels and adjacent to tho left hand sides of said gear wheels and carrying
points, are registering wheels or discs L, LII and I each of which is secured
to one of said gear wheels and moves in unison therewith. Those registering wheels
are also numbered on their peripheries with six series of figures from 1 to 0
inclusive, each of which series of figures commencing opposite to one of the carrying
points on the gear wheel adjacent thereto.
On the end of the shaft & opposite the carrying points on the gear wheel is
adjustably secured a laterally projecting arm or lever M adapted to le engaged by
the carrying points on the gear wheel I as it rotates the rock shaft and on the
opposite end of the shaft k opposite the gear wheel is a downwardly projecting
lever or arm N having pivoted thereto a dog n engaging with the teeth in the gear
wheel so that the rocking of the shaft by the engagement of the carrying
point on the gear wheel I moves the lever N and the dog a pivoted thereto and
engaging with the teeth in the gear wheel l¹ so as to carry the gear wheel l¹ forward
one tooth. Likewise on the end of the shaft & is secured a like adjustable arm or
lover M adapted to engage with the carrying points on the gear wheel and on
the opposite end of the said shaft K₁ is secured a like lever N carrying a dog n¹
engaging with the teeth on the gear wheel and on the end of the shaft a like
lever M adapted to engage the carrying points on the gear wheel and on the
opposite end of the shaft K' a like lover and dog n engaging with the teeth of
the gear wheel F, and on the end of the shaft a like lever M adapted to engage
the carrying points on the gear wheel and on the opposite end of the shaft k
a like lever N and dog n³ engaging with the foeth of the gear wheel I, each of which
series of shafts and the mechanism thereon operate in like manner as does the
shaft and levers M and N and dog n connected therewith, first hereinbefore
described and by means of which when the wheel is moved forward ten teeth the
wheel is carried forward one tooth; and likewise the carrying forward of the
wheel ten teeth moves the wheel forward one tooth, and so on throughout
the whole serios, thus carrying by tons from the right to the left of said series of
registering wheels.
On the rear side of the frame plate B below the shafts k, &c., are bearings K' in
which bearings are pivoted dogs O which project forward through openings in the
frame plate B beneath the gear wheels, h, and with the teeth of which gear
wheels said dogs are adapted to engage. And in vertical slides o on the back side of
the frame plnte B below said dogs O are vertically sliding plates PPP and one
of said plates rosting upon ouch of said groups of key lavors (and so as to
bo actuated thereby, on the upper edge of each of said plates is also secured an
upwardly projecting lug p adapted to contact with and raise the dog O corresponding
therewith into engagement with the gear wheels or &c., as the case may be when
the plate having such lug p thereon is raised by the operation of the key lovers of the
group upon which it rests.
l
On the platos P, P, and Pare also secured wedged shaped projections 97'7”.
and and on a bar Q which is secured between the side frames A A at the rear of
the frame plate B and the vertically sliding plates P, P1 P2 and P3, are horizontal
bearings or guides I (see Figures 7 and 8). "In these guides It are short horizontally
sliding bars R1, R2 and R3 said bars being of sufficient length to reach from one of
the wedges g to another near the inner edges of the bars R and R. 1 place pins r
and therein which operate to limit the lateral movement of all of said bars so that if

page_text: one of the wedges 9 be raised by movement of one of the plates P it will push all of
the bars together and toward the left until the pins r¹ contact with the guides or
bearings Radjacent thereto, and so long as the wedge 9 remains in that position none
of the other wedges q' q³ or g³ can be raised so as to pass between the ends of the
bars adjacent thereto; and in like manner the raising of either of the wedges 7' 7²
or operates to move the bars R R2 and R3 laterally so as to prevent the raising of
any of the other wedges thus the raising of each wedge operates to lock or prevent
the raising of all the others until it is lowered back to its normal position, and as the
plate P and wedge y thereon is operated only by the group C of the key levers, and
each of the other plates and wedges described are likewise each operated by a single
group of key lovers only it is manifest that keys in but one group can he depressed at
the same time, as the operation of keys in one group operates through the mechanism
described to lock for the time such key or keys are depressed, the keys in all the
other groups.
It will be observed that the outer end of the bar K, and both ends of the bar R³
and the outer end of the bar R³ have short sections hingel thereto in such a
manner that as the wedges pass upward they will remain rigid, but will yield as the
wedge falls back to its normal position. The object of this construction being to
prevent the wedge sticking. a small spring operating to return the hinged portion ²
back to its normal position when the wedge has been withdrawn.
در
Across the lower part of the machine near the rear edges of the side frames A A,
I place a rod S which operates as a rest for the rear ends S' of the key levers, and
somewhat above the roil S and in the frame at the rear ends S' of the key levers I
place a rod T upon which I mount supplementary levers T one of which is coupled
to each of the key levers representing cents from 1 to 4 inclusive in the group
and from 10 to 40 in the group (and from $1.00 to $4.00 in the group (and
from $10.00 to $40.00 in the group C, for the purpose of more nearly equalizing the
movement or traverse of said key levers with the traverse of the remaining key levers
as hereinafter described.
The outer ends of these supplementary levers Tare coupled each to its respective
key lever at a point t between the axis A of the key levers and the foet d d¹ d² and d
of the rack bars D D and D at such varying distances as may be required to
equalize their movement, the said key lovers to which said supplementary levers T
are coupled being cut away beneath the feet & &c., of the rack bars so that the feet of
the rack bars rest upon the supplementary lovers T' instead of on the rack bars
themselves, so that when the rear end of the rack bar is raised the supplementary
levers Tacts upon the foot of the rack bar to raise it, in lieu of the key lever itself,
as in other cases where the key lever is not provided with a supplementary lever T
thus allowing a much greater traverse of the key lever than would otherwise be
possible this operation being fully illustrated by the full and dotted lines in Figure 6.
On the key levers at the rear of the rack bar feet d d d and d³ are projections U
curving toward the rear faces of said rack bar feet, these projections being of different
lengths, as illustrated in Figure 5 according to the distances of the traverse of the
several key levers and are adapted to enter depressions V in the rear faces of the rack
bar feet when raised and lock the rack bar foot in such position until the key lever is
released. They also operate to prevent the rack bar from being thrown up too far by
a sudden or sharp blow upon the key lever. The said curved projection U on the
key lever also engages with the lower edges of the vertically sliding plates P P¹ P*
and operating the same together with the locking mechanism thereon hereinbefore
described.
On each edge of the rack bars D D' D and D³ below the racks c thereon are
ratchet teeth 1 and 2 in which dogs 3 and 4 operate; these dogs 3 and 4 being
coupled together by means of spiral retracting springs 5 which operate to normally
force the dogs 3 and 4 into contact with the ratchet teeth 1 and 2. Across the front
of the machine in front of the dogs 3 and 4 is a horizontally moving bar 6, the ends
thereof being pivoted to one of the arms 7 of the bell-crank lovers 8 and 9 pivoted to

page_text: the face of the frame plate B of the machine, so that the movement of said bell-crank
levers operates to move the har 6 back and forth across the front of the machine. On
the bar are pins 10 and 11 which engage with like pas 12 and 13 in the lugs 3
and by means whereof the movament of the lar 6 to the right or left serv to move
the dogs 3 and 4 in and out of engagement with the teeth and 2 on the rack bars
as hereinafter set forth. Centrally on the fees of the rack bars D, D¹ D* and D³ are
vertical V-smped projections 14 and on the rear of the rod or bar 6 are spring
hooks 15 (sen detail view Figure 4) the vertical projections 11 extending upward on
the rack bars jnst far enough so that, when the rack bars are at their lowest point,
the hooks 15 will pass the upper ends thereof but will engage therewith when raised
above that point.
To the arms 16 of the hell-crank levers 8 and 9 are coupled downwardly projecting
links 17 and 18, the lower ends of which are pivoted to releasing levers 19, 20 pivoted
on the rod at each side of the machine, the outer ends of which levers bring
connected together by a cross-bar 21 in front of the keys.
It will be observed that the dogs are at all times normally engaged with the
teeth 2 on the rack bars except during the times the rack bars are returning to their
normal positions; this is accomplished by depressing the releasing levers 19 and 20
which operates the hell-crank lever 8 and so as to move the horizontal bar 6 to the
right, which operation releases the dogs 4 from the teeth 2 in the rack bars, and at
the same time moves the hooks 15 into engagement with the vertical ribs 11 on the
rack bars which prevents the re-engagement of the dogs 4 with the teeth 2 in the rnck
bars until the rack hirs have passed to their lowest point when the upper ends of the
vertical ris 14 pass below said hooks 15 which allows the sliding lar 6 to move back
towards the left to its normal position, with the dogs 4 again in engagement with the
teeth on the rack bars. The inner els 22 of the releasing bars 19 and 20 are also
turned downward and pass through openings in the base B where they engage with
the spring catches 23 at the rear end of a cash drawer 24 mounted in the base of the
case of the machine and operate to retain the cash drawer 24 in a close position until
released by depressing the outer evils of said releasing levers 19 and 20),
In the bottom of the case at the rear end of the cash drawer 24, 1 also place a
retracting spring 25 which, when the drawer 24 is closed is compressed and which
operates when the drawer is released by the operation of the releasing levers 19 and 20
to throw the drawer 24 open.
To the left hand side of the frame A A, I secure an alarm-hell 26 and also a
pivoted hammer-lever 27 which has a spring catch 28 adapted to engage with a pin 29
on the link 17. When the releasing levers 19 and 20 are depressed the hammer 31 is
drawn back from the bell and when they are released the retracting spring 30 secured
to the bell-lammor lever 27 cause it to strike the bell 26 and sound an alarm, which
is done each time the releasing lovers 19 and 20 are depressed.
In operation the depressing of any one of the key-lovers in the groups C, C³, C³, C³
thereof raises the rack bar foot and rack bar thereon far enough to turn the indicating
and registering wheels connected therewith the proper distance to indicate and
rogister the amount designated by said key, and at the same time operates the
carrying mechanism so as to carry forward by tons, when necessary, so that each
amount indicated by the key or keys depressed is indicated on the indientor wheels,
and at the samo time added to the aggregate amount previously indicated and
registered.
In the description hereinbefore given of my machine, I have referred only to a
decimal currency, but it is obvious that by varying the number of groups of keys and
also the number of keys in each group, and also the arrangement of the figures on
the registering wheels my machine can be equally well adapted to indicato pounds,
shillings and pence, or such other currency as may be desired.
The further description of the operation of the other parts of the mechanism
having been hereinbefore fully described and set forth in the description thereof,
