Improvements in Cash Registering Apparatus or Check Tills.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
The invention consists in the construction, arrangement and combination.of the
various parts, and particularly in the following features:
In the construction and combination of a lock for all the register operating keys
(both those which have been operated and those remaining unoperated), and a cash
drawer which can be freely opened, with connections between the drawer and the
lock, whereby the opening of the drawer releases the lock for the keys and returns
the operated keys to their initial position.
Further, in a lock which holds the drawer open until one or more of the keys are
operated, which operation releases the drawer, which is then drawn closed by a
spring, put under tension by the opening of the drawer.
Further in the construction of a preliminary support for the keys in their partially
depressed position which, without releasing the drawer lock, permits any number of
keys to be depressed successively, and which completes the movement of all the
partially operated keys to effect the registration of all, upon completely depressing
any of the keys.
Further, in the construction of precautionary devices to compel the completion
of the movements of the various devices after they have been started to prevent
fraudulent tampering with the machine.
Further, in the construction of the register wheels, and in the actuating devices
for re-setting them to zero, and in the detail construction of the various parts, all as.
more fully hereinafter described.

Fig. 25 is a perspective view of one of the formed flanges.
The supporting frame comprises the sides 1, connected by suitable connecting
bars or shafts 2.
3 is a cash drawer on top of the sides of which are the supporting and guide
strips 4, which run between the rollers 5 above and below the overhanging edge of
the strips 4, these rollers being journaled on suitable pins or shafts on the sides near
the front, and shown in Figs. 1 and 2.
On the rear face of the drawer is a bracket 31, in which is pivoted a dog 6, held
in contact with the upper face of the bar 7, by the tension of a coil spring 8 (see
Figs. 1 and 3).
In the open position of the cash drawer this dog engages in the locking bar or
notch 9 in the upper face of the bar 7.
10 is a universal bar having the downwardly and inwardly extending arms 11 at
its ends, the inner ends of which are pivoted to extensions 12 Figs. 1 and 3 of the
sides of the cash drawer.
13 are springs supported on those extensions supporting the universal bar 10
normally in its highest position.
14 is a pin on that universal bar which in the open position of the cash drawer is
adapted to engage with the actuating arm of the dog 6.
15 are the key levers journaled upon the transverse shaft 16 above the cash
drawer, the forward ends of the keys being provided with suitable finger pieces 17,
and the rear ends having connected to them the usual tablet rods 18 at their upper
ends carrying the tablets 19.
These tablets and tablet rods are shown only in Fig. 1, in dotted lines, omitting
them from the other figures as unnecessarily complicating the drawings, for their
construction is well understood in this class of cash register.
Each of these key levers forward of its pivotal point is provided with a down-
wardly extending arm 20, the lower end of which, in the open position of the
drawer, is directly above the universal bar 10, as shown in Fig. 2, so that the
depression of any key will always depress the universal bar 10 and the pin 14
thereon and release the lock 6, permitting the drawer to be closed. The drawer
may be closed by any suitable spring.
The drawer closing mechanism, as shown, comprises the springs 22 (Figs. 1
and 2) secured to one of the cross-bars 2 at the top of the machine at their upper
ends, and at their lower ends to blocks or plates 23 having laterally projecting

page_text: pins or screws 21 which engage in slots 24 in the sides 1 of the frame. Figs. 2, 12
and 13.)
The pins 21 are connected by the link 25 to the short arm of a bell-crank
lever 26 journaled near the top of the machine, the long arms of which extend
down beside the drawer outside the frame and are provided with slots 27 which
engage over the pins 28 in the sides of the drawer. (Fig. 2.)
29 are rollers journaled on the pins 28 and running in the horizontal guide
ways 30 in the side of the machine.
Opening the drawer draws the rollers 29 to the front of the guide ways 30, rocks
the bell-crank lever upon its pivotal point and lowers the blocks or plates 23 putting
the springs 22 under tension. Upon the releasing of the drawer lock, the springs 22
lift the blocks or plates 23, rock the bell-crank lever on its pivot and draw the
drawer to its closed position.
32 is a rubber buffer in the end of the bracket 31 adapted to strike against
the buffer block 33 secured in the rear of the machine. (Figs. 3, 10 and 11.)
This block has a forwardly projecting arm 34 in the end of which is pivoted the
recoil check pawl 35, the lower end 36 of which is of segmental circular
configuration, as plainly shown in Figs. 2, 10 and 11.
As the drawer reaches the end of its inward movement the pin 37 on the
bracket 31 strikes the front face of the re-coil check pawl 35, swings it on its pivot
into a horizontal position above the pin, as shown in Fig. 10, and just at the moment
that the buffer strikes the buffer block 33, the segmental circular face 36 of the
pawl will engage in front of the pin 37, and the recoil of the drawer will. he

drawer, without in any way affecting such movement of the drawer.
a noiseless closing of the drawer is effected without any apparent recoil
movement.
It is desirable in a drawer of this kind to provide mechanism which will compel
the operator after partially opening the drawer to continue the opening movement
until the drawer has been entirely opened and in closing to prevent re-opening until
it has reached the limit of its inward movement. Ordinary ratchet and pawls
would effect this result, but would make an unpleasant clicking sound.
This invention embodies a noiseless double pawl of the following construction ;
40 is a rack bar secured to the frame of the machine beneath the cash drawer in
close proximity to the bar 7 and parallel therewith, (see Figs. 1, 3, and 5).
41 and 42 are opposite extending pawls pivoted on a common pin 43 extending
from the side of the bracket 31.
Each of these pawls at their ends are provided with a tooth or shoulder 44, and
46 is
an inclined upwardly, extending tongue 45 beyond such tooth or shoulder.
a plate or shoe sliding on the rack bar 40 and having springs 47 engaging
the sides of such rack bar to act as a friction holding device or brake for
such plate.
At each end this plate is provided with the upwardly extending lips or lugs 50,
the distance between these lugs being slightly less than the distance between the
shoulders 44 on the pawls.
51 and 52 are inclined stop bearings at the front and rear ends of the rack bar
respectively, as plainly shown in Fig. 1.
In the closed position of the cash drawer the end of the plate 46, striking the
stop 3 will stop that plate, while the further movement of the drawer will move
the pawl 41 beyond, its tooth 44 being disengaged from the lip or lug 50 because
of the engagement of the inclined bearing 45 against the inclined stop 52 on the
rack bar. The movement of the two pawls in relation to the plate will thus cause
the tooth 44 on the pawl 42 to engage behind the forward lip 50, so that when the
drawer is drawn out the pawl 42 will push the plate 46 with it, at the same time
the tooth 44 on the pawl 41 will be moved along just above the rack bar, being

page_text: prevented from engagement therewith in such movement because that pawl rests on
the rear lip 50, but if the operator should attempt after a partial opening of the
drawer to close it, the friction brake or springs 47 holding the plate stationary, the
pawl will be free to engage with the rack bar as it was moved inward by the drawer,
and would thus prevent such inward movement until the drawer had reached its
uttermost forward position, when the pawl 42 will be lifted off the plate and the
pawl 41 engaged thereon behind the lip 50 and thus in closing the drawer prevent
its being reopened until the plate has again been shifted at the opposite end
of the movement. At no time in the movement of the drawer does the pawl
ride on the rack bar and it is therefore absolutely noiseless and yet perfectly sure
in its operation.
The pawls 41 and 42 may be gravity pawls, but I prefer to connect them by a
spring 55 to make them more positive in operation.
54 is a pin extending from the locking dog 6 over the pawl 41 and in such
relation to the pawl that the pawl will hold it from engaging with its locking
notch 9 until the pawl 41 has been shifted longitudinally to engage behind the
lip 50 on the plate 46.
This prevents the locking of the drawer open until the pawls have been shifted
at the end of the movement so that the drawer can be closed upon operation
of a key.
56 is a universal bar extending across the machine above the cash drawer beneath
the keys, (see Figs. 1, 3, 5, 6 and 7). It is suspended at its ends on the links 57
which are rigidly secured to the ends of the universal bar, or may be made integral
therewith and are pivoted at their upper ends to the sides of the machine.
This
bar has an upper face 58 Figs. 6 and 7 which is adapted to swing under the lower
end of the arms 20 on the keys and prevent the operation of any of the keys until
it has been thrown out of the way.
On the inner face of this bar is a locking flange 59, under which the lip 60 on
the forward edge of the lower end of the arm 20 of all the keys is adapted to
engage in their operated position, as plainly shown in Fig. 1. Thus, this bar acts
as a lock for the operated and unoperated keys in the closed position of the cash
drawer.
The universal bar 56 is held normally in the position shown in Fig. 1 by the
tension of the coiled springs 61 Figs. 6 and 7 connected at one end to the links 57
and at the other end to the frame of the machine. Upon the opening of the cash
drawer this universal bar is swung forwardly by the bar 62 secured to one of the
links 57 at its forward end, and at its rear end engaging in front of the lug 63 on
the cash drawer.
This bar 62 has a limited horizontal swinging movement by means of which it
may be moved into and out of the path of the lug 63.
64 is a spring connected at one end to the forward end of the bar 62 and at the
other end to the universal bar 56 and acting with its tension to norinally hold that
bar in the path of the lug 63.
65 Fig. 1 is a lug or shoulder on the under side of the universal bar 56 with
which a finger 66 Fig. 1 at the rear of the cash drawer is adapted to engage in the
forward position of the drawer.
67 is a universal bar resting on top of the keys near their rear end (Figs. 1, 2, 6,
7 and 8). At the ends this bar is connected to the long arm 68 of bell crank levers
which are pivoted at their elbows near the ends of the shaft 16, the short arm 67*
of which extends downwardly from said shaft.
At the lower ends of the arm 67 are pivoted the dogs 70 having a tooth 71
adapted to engage with the detent or shoulder 72 in the top of the cash drawer.
73 are springs acting to hold the dogs in engagement with the top of the cash
drawer.
On the long arm 68 of the bell-crank lever are the pins 76 having the bevel
faces 77 at their lower ends Figs. 1, 6 and 7.
Extending above the pivotal point of each key is a register actuating arm 80

page_text: carrying a spring pawl 81 adapted to engage with the teeth of a register wheel 82
one register wheel for each key. The construction and operation of these register
wheels I will describe further on.
83 are a higher series of registering wheels or carrying wheels to register
multiples of the value of the wheels 82. Each key has a spring 84 acting to hold
the key in its initial position and to return it to such position when released by the
lock.
The operation of the parts last described is as follows: There being no lock to
hold the drawer in its closed position the first movement of the operator is to open
the drawer, the parts being in the position shown in Fig. 1. Until the drawer is
opened all the keys will be locked against operation by the universal bar 56. The
operator pulling the cash drawer open, the lug 63 on the cash drawer will strike
the bar 62 which will positively swing out the universal bar 56 as shown in Fig. 6.
This movement will release the previously operated keys by removing the locking
flange 59 from over the lip 60 on the operated keys, when such keys will be
returned to their initial position by the tension of the springs 84.
As the drawer continues its outward movement the tooth 71 on the dog 70 will
engage with a detent or shoulder 72 and rock the bell-crank lever which carries the
bar 67 forcing down that universal bar.
This prevents the operator from holding down the forward end of the previously
operated key while opening the drawer, and also prevents the operation of any key
during the interval while the universal bar 56 is held from beneath the arms 20 by
the bar 62.
As the universal bar 67 descends, the inclined face 77 on the pin 76 will strike
the side of the bar 62 Fig. 7 and shift it laterally out of the path of the lug 63
when the spring 61 will immediately draw the universal bar 56 beneath the arms 20
on the keys. Simultaneously with this movement the teeth 71 on the dog 70 will
be disengaged from the notch 72 by fulcrumming upon the stationary pin 85 which
is secured to the side of the machine beneath that dog as shown in Fig. 7. During
the further forward movement of the drawer the keys will remain in their locked
position until the finger 66 strikes the lug 65 as the drawer reaches the end of its
outward movement and again swings the universal bar from beneath the keys
permitting their operation (see Fig. 5).
During the downward movement of the universal bar 67 the spring pawls 86
engage with the stationary rack 87 Figs. 1 and 8 on the frame of the machine,
compelling a completion of the downward movement of that universal bar after it
has started.
If the operator depresses one of the keys, the drawer being open, it will raise
the universal bar 67 and rock its supporting bell crank levers and the dog 70 will
be thrown forward sliding on the pin 85 until the notch 78 in that dog engages
over the pin 85 which will lock the universal bar up until the cash drawer is closed,
closing the cash drawer will strike the end of the dog 70 and disengage the notch
from the pin permitting the universal bar 67 to rest upon the top of the operated
keys and be lowered with them when the drawer is next opened.
The object of locking up this universal bar is to prevent it being locked down
over a partially operated key resting on the check pawls 91 Figs. 1 and 2 by
means of the spring pawls 86 engaging the rack 87. If this happened it would
lock the key against movement in either direction.
To get the desired co-operation in movement between the pawls 41 and 42 and
the bar 56, so that the drawer cannot be held open by the pawl 41 when part way
out, at the point where the universal bar 56 is out of its locking position I make
the smooth space 90 Figs. 1 and 3 on the rack bar 40 at the end of the movement
of the pawls so that if the operator should release his hold of the cash drawer near
the end of its movement and when the tooth 44 on the pawl 41 is passing over the
plain space 90, the spring would draw the drawer back again until that pawl
engages the rack bar, at the same time withdrawing the finger 66 from the
universal bar and permitting it to be drawn back by the spring 61 beneath the

page_text: keys, thus compelling the operator to draw the drawer to its uttermost outward
position and shift the pawls 41 and 42, before he can lock it open in such a position
that the keys can be operated.
The parts being in this position a key or keys may be operated, which in the
manner previously described will cause the arm 20 thereon to depress the universal
bar 10 and will release the lock which holds the drawer open. As soon as the
drawer begins to close, the finger 66 will be withdrawn from the universal bar 56
and that bar will be swung under the arms 20 on the keys and against the rear face
of the arms 20 such of the key levers as have been operated locking them in
their operated position as previously described and also locking the unoperated
keys and the parts will return to the position shown in Fig. 2, the drawer being
closed.
In a cash register embodying a large number of keys which extend over a
considerable space it is often difficult or impossible to actuate the desired number
of keys simultaneously and this construction permits of the partial depression of
any number of keys, which will be held in such position until one or more of the
keys is depressed to its limit, when the actuating mechanism for closing the cash
drawer will complete the movement and effect the registration with all the other
partially depressed keys.
This is preferably of the following construction. In the initial movement of the
universal bar 10, effected through the operation of a key, the dog 6 is not
disengaged to unlock the drawer and during this initial movement the rear end of
the key lever passes up above a check pawl 91 one for each key, all being pivoted
upon the cross bar 92 secured in the lower ends of the plates 23, and resting near
their ends on the universal bar 94, their forwardly projecting ends being in the
path of the rear end of the key as previously described. (Figs. 1, 2, 12, 13.)
As soon as the key has passed above this check pawl the operator may release
his hold and it will be held in its partially operated position as indicated in Fig. 6
in dotted lines. A number of keys may thus be successively partially operated and
held by the check pawls as described, when a complete depression of any one key
will release the dog 6 and permit the spring 22 to act to close the drawer, in which
movement the plates 23 will be lifted, carrying also the check pawls and the keys
resting thereon, causing all the partially operated keys to complete their movement
and effect the registration.
As soon as the keys have reached the limit of their movement the plates 23 will
be rocked by means of cam-bearings 95 on the fingers 96 thereon bearing against
pins 97 which will throw the check pawls from beneath the keys, and thus permit
of the return of the keys when the drawer is opened.
The drawing open of the drawer through the mechanism previously described will
return the check pawls to their initial position.
A lock is provided to prevent the closing of the drawer in case a key is but
partially depressed, which is illustrated in Figs. 1 and 4, which consists of a
lever 100 pivoted at one end to the universal bar 56 and fulcrumed upon the
pin 101, in the side of the machine. In case the key is partially depressed so that
the locking lug 60 rests behind the bar instead of beneath the flange 59 holding the
universal bar from swinging in its proper position for locking both the operated
and unoperated keys, the lower end of the lever 100 will rest upon the upper
surface of the drawer and engage into a notch 102 preventing the closing of the
drawer until the key is either returned to its initial position or fully depressed,
when the swinging of the universal bar will lift the lever out of the notch in the
drawer and permit the drawer to close.
The register wheels are made of sheet metal, (see Figs. 21 to 25) comprising a
sheet metal disk 103 having the central aperture 104, the peripheral teeth 105
and the circular series of apertures 106 near the outer edge. The numbered flange
on the wheel I form from a strip of sheet metal 107 having integral therewith the
teeth 108.
This strip I shape into a ring as shown in Fig. 25 securing the ends together,

page_text: then passing the teeth 108 through the apertures 106 and bending them on the
opposite side to secure the flange in position, thus I am enabled to stamp out all
parts of these registering wheels from sheet metal, which greatly simplifies the
construction and cheapens the cost, at the same time enabling me to make them.
more accurate.
The toothed disks are provided with the carrying teeth 109 secured beside one.
of the teeth on the disk 103. Of these wheels I have shown two series, the unit
registering wheels actuated by the keys and the carrying wheels.
The units
register wheels are journaled upon a shaft 110, while the carrying wheels are
journaled on a shaft 111 (see Figs. 1 and 15).
On each side of the disks of the register wheels are the washers 112 having
keys 113 engaging in the key way 114, extending longitudinally of the shaft and
between these washers are the spacing sleeves 115 which may loosely turn on the
shaft or may be slidingly feathered thereon their only function being to space the
wheels the desired distance apart.
All of the wheels are clamped tightly between their collars by means of a coile I
spring 116, which is sleeved at one end of the shaft and bears against a stationary
collar 117 on the shaft at one end and against the end registering wheel on the
other end. Thus I dispense with all pawls for holding the registering wheels by
simply holding them frictionally between the collars, sufficient power being applied
through the coiled spring to prevent any possible overthrow of the wheels, no matter
how hard the operator may depress the key levers.
One revolution of each of the units register wheels will move the carrying
wheels one notch, by the engagement of the carrying teeth with one of the
carrying wheels.
The edges or teeth in the two series of wheels are arranged slightly out of
line as shown in full lines in Fig. 15, so that the carrying teeth in the units wheels
will be in line with the teeth on the carrying wheels. Another object which I have
in loosely journalling the registering wheels upon the shafts is to permit of
simultaneously resetting them by means of a crank applied to the shafts of the
wheels or to a pinion meshing with gear wheels on the register shafts.
resetting mechanism is shown in Figs. 14, 15, 16, 17, 18, 19, and 20.
This
120 is a gear wheel on the register shaft 110 and 121 is a gear wheel on the
registering shaft 111.
122 is a pinion meshing with both these wheels and journaled in bearings on
the frame. Over the end of this pinion is a slotted plate 123 and in the slot in the
plate is a block 124 Fig. 18 backed by a spring 125 in the interior of the pinion 122
which is hollow.
126 is the crank having a slot 127 in its head 128.
To turn the pinion the operator engages the head 128 against the block 124 and
pushes the block in until the slot 127 registers with the edge of the plate 123 when.
he may turn the crank and thus rotate the pinion, and the registering shafts, through
the gearing described.
To stop the registering wheels at zero, I loosen the compression springs 116 to
reduce the friction of the washers 112 upon the registering wheels and also shift
one set of wheels, or the shaft of one set of wheels) longitudinally so as to move
the carrying teeth of the unit wheels out of the path of the teeth of the carrying
wheels. This may be done by a spring 130 bearing on the outside of the collar 117
on the shaft 111.
The tension of the springs 116 and of the spring 130 Fig. 15 is released and
applied by the movement of the wedge 131 on the bar 132, Fig. 18 engaging
against an inclined bearing on the yoke 133, which at its opposite ends is aperture.l
to embrace the register wheel shafts and which bears with its inner face against
the end spacing sleeves on both of said shafts. The bar 132 is connected to the
curved lever 134 which at its lower end has a slot 135 engaging over a pin 136.
about which it has a sliding pivotal movement. Drawing up the lever 134 from

page_text: the initial position shown in Fig. 17 to the position shown in Figure 14 will draw
the wedge from its bearing with the yoke and permit the expansion of the springs 116
and the spring 130 loosening the tension on all the registering wheels of both sèries
and shifting the registering wheels of the carrying series so that their teeth are out
of the path of the carrying lugs on the unit series. The different positions of these
wheels are shown in full and dotted lines in Fig. 15.
The movement of the lever 134 also throws into the desired relation to the
registering wheels the stops, or what I call combs.
The combs 137 for the carrying wheels is supported on the universal bar 138
which is pivoted at its ends in the frame of the machine in such position that it will
fall by gravity when released, so that its teeth are in the path of the lugs 109 on
the carrying wheels. Pivoted on this universal bar is a spring actuated tripping
lever 139 having a notch 140 adapted to engage a stationary pin 141 which acts
as a hook or latch to hold the comb in its inoperative position. The lever 134 in.
turning about its pivot 136 strikes the end of the lever 139 and disengages the notch
from the pin 141, therby permitting the comb to fall into its operative position,
shown in Fig. 14.
The lower comb 15 is secured to the universal bar 151 pivoted at its ends in the
frame of the machine and is provided with an apertured plate 152 with which the
hooked finger 153 on the bar 132 engages, so that as this bar is drawn up by
the lever 134 it carries the comb upward so that its teeth are moved into the path of
the carrying teeth on the units wheels.
This comb is locked in this position by means of the latch or hook 155, which drops
over the end of the plate 152, as shown in Fig. 20.
The parts being in this position the operator turning the crank will rotate the
gear wheels and the registering shafts and the washers 112 will turn with the shafts
and they will have sufficient frictional engagement with the register wheels to
carry the wheels with them until the carrying teeth of the units series strikes the
teeth of the comb 137 and until the stop block 109 Fig. 15 on the carrying wheels
strikes the teeth of the comb 150. When all of the wheels are arranged in the same
relation to the combs they will have been reset to zero ready to commence a new
registration.
As soon as this is accomplished the operator pushes down the lever 134 which
returns the parts to the position shown in Fig. 17, moving the combs away from
the register wheels.
I prefer to lock the keys while all the register wheels are being reset and to
do this I provide a universal bar 160 pivoted above the rear end of the key levers
having an actuating cam plate 161 at one end which is adapted to be acted upon
by the pin 162 on the bar 132 so that in withdrawing that bar, it will permit the
bar 160 to turn upon its pivot and act as a stop for all the keys, while the return of
the bar 132 its pin 162 acting upon the cam plate 161 will lift the universal bar 160
out of the way of the keys.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :--
