Improvements in Cash Registers and Indicators.
I HERBERT JOHN HADDAN, of the Firm of Herbert Haddan and Co. of
18, Buckingham Street, Strand, W.C. London, Consulting Engineer, do hereby
declare the nature of this invention, a communication to me from abroad by The
National Cash Register Company, of Dayton, State of Ohio, United States of
America, 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 that class of cash registers wherein a plurality of keys
of different values are employed to effect the operation of a registering device by
which the sums of the values of the keys operated are preserved, and to cause the
display of an indicator or indication agreeing in value to the key operated. It has
for its object the improvement in the construction and operation of such cash
registers, whereby they are rendered more effective and less liable to become
inoperative through rough handling or improper manipulation.
To this end the improvements consist in novel structures, combinations and modes
of operation of parts hereinafter set forth, reference being had to the accompanying

Referring to said drawings it should be stated that the several improvements
embraced by the present invention are embodied in a perfect machine adapted to
the various exigencies which a machine in practical use should be capable of
meeting; and, although the various improvements are shown in a single organization
it should be stated that they may be employed in such machines either separately
or together.
This complete embodiment of the invention comprises a plurality of keys which
may be arranged in two or more independent banks, with indicating, registering
and printing mechanisms, whereby upon the operation of any key its value is
indicated and registered and printed upon a record-strip or ticket.
The machine includes, as an automatic connection between the keys and the
registering mechanism, a differential plate capable of imparting a movement to
the registering device corresponding to the value of the key operating the plate ;
and where two independent banks of keys are used each bank will be provided
with a differential plate independent of the other, each to operate its own registering
mechanism.
The machine furthermore includes a key-controller, whereby upon the com-
mencement of the movement of a key it is compelled to move to the limit of its
stroke in one direction before it can be returned to its normal position, and by
which after it has reached the limit of its stroke in one direction it is compelled to
return to its normal position before being moved again; the said key-controller.
also embracing a key-coupler by which two keys each in different banks may be
coupled together so as to be operated simultaneously--both keys being at the same
time under the control of the key-controller.
It furthermore includes a key-locking device by which only one key may be
operated at a time, or by which one key in a bank may be operated at a time,
but permitting the simultaneous operation of two keys of different banks
when two independent banks are used; and with the same key-locking device,
or with some other locking device, is combined a keeper under the control of
a cash drawer with which the machine is provided, by which while the drawer

page_text: or its lid is open the mechanism of the register is locked against movement
and which upon being closed will release such mechanism and permit it to operate
as before.
The machine further includes a rotary shaft, either common to all of the keys of
the machine, or made in sections, and one section common to one bank of keys and the
other section common to the other bank of keys, whereby upon its movement
the drawer is unlocked, the previously exposed indicating tablet is released and
permitted to return to its normal position, and the alarm is sounded.
It also includes a means, after the drawer has been unlocked, of positively moving
said drawer either partially or wholly to its open position, and which means upon
the return of the key to its normal position forms no obstruction for the return of
the drawer to its closed position.
Referring now to Figs. 1 to 6 inclusive, it will be understood that the improved
register embraces a plurality of keys of different values, a registering mechanism B
adapted to be operated upon the movement of the keys to preserve the sums of
their values, and an indicating mechanism C also adapted to be operated upon the
movement of the keys to indicate the value of the keys operated.
The register embracing these three instrumentalities is shown as divided into two
distinct sets Y, Z, thereof, adapted to register and indicate, for instance, cents and
dollars, and there is also shown a third distinct set X thereof, adapted to register
and indicate the sale or sales of a specific article. These sets are so arranged that
the operation of any one of the keys in the cents bank Y will cause the operation
of the register B and the indicator C; the operation of any key in the bank Z
will cause the operation of the register B' and the exposing of an indicator C';
while the operation of the single key X will actuate its register B³ and display its
indicator C.
The keys A of each of the banks are in the form of levers oscillating upon a
rod 100, common to them all, that extends between the side frames W of the
machine. These keys are formed from sheet metal and each has a depressed seat
to straddle a groove in the rod 100, the sides of which groove hold each key in
proper position, see Fig. 11. The outer ends of the keys are bent so that their
ends will lie in different planes, and their inner ends extend forwardly each in line
with or partially entering a guide slot 1 in a fixed back plate D extending between
the side frames; the guide slots 1 being of such length as to permit the full
vibration of the keys and to guide and steady them during such vibration, which
slots, with the grooved seats in the rod 100, serve to keep the keys in position and
greatly facilitate their easy assembling in the machine.
The registering mechanism may be of any approved form, adapted to be actuated,
for instance, by the movement of a master wheel a, and this master wheel may
obviously be mounted at any point in the machine found most convenient.
The registering mechanisms B and B are of substantially the same construction
and are operated in substantially the same manner, and hence a description of one
will suffice for both; the registering mechanism B³ for the key X being of any
well known form and shown as consisting of a series of adding wheels operated
directly from the key. With each mechanism B B₁ the master wheel a, see
Figs. 8 and 9, in a train of adding wheels b, &c., is mounted to rotate on a vertical
spindle projecting from a horizontal top plate V, extending between the side frames
of the machine. The master wheel is formed with an extended hub whose
periphery is serrated to form a ratchet e, adapted to be engaged by the teeth of the
ratch-bar or pawl f, arranged to reciprocate horizontally or otherwise move over
the top plate V in proximity to the ratchet e.
In order to cause the ratch-bar of the master wheel of each registering
mechanism B and B₁ to partake of certain predetermined degrees of movement
corresponding to the values of the different keys that are combined with said
master wheel, there is provided a differential plate E, Fig. 4, co-operating with one
bank of keys, as the bank Y, and another similar plate E' co-operating with the
bank Z; such plate being substantially the same in construction and operation, a

page_text: description of one only need be given. The differential plate is arranged at the
rear of the machine immediately against the back plate D, to which it is steadied
by guides 40 passing through slots 41, and in the present embodiment has secured.
to it a bent plate or arm g to which is pivoted the ratch-bar f, Figs. 1, 4, 8 and 9.
The differential plate is otherwise supported so as to move longitudinally by a pair
of links 42 hung from the cross bar of the machine frame. The lower end of the
plate is supported immediately above the rear ends of the keys so that in its
movement it will pass above them without interference, and in so doing its edge
presents a stop against the movement of a second key until it returns to its normal
position. The differential plate is made to move lengthwise differentially by the
action of the several keys with which it is combined through the engagement of
said keys each with one of a series of slots 2 that are formed to extend from the
lower edge of the plate upwardly above the rear end of each key, and are
differentially inclined from a vertical position, as shown in Fig. 4; and with their
lower or entering ends in the normal position of the plate co-inciding with the guide
slots 1 of the back plate D, which guide slots thus prevent the lateral displacement
of the keys in moving the differential plate.
The slot of the differential plate at the left hand of the view shown in Fig. 4,
entered by the rear end of the units key when its front end is depressed, is but
slightly inclined from the vertica!, so that as the key end moves upward it will
force the plate E and the connected ratch-bar longitudinally just far enough to
produce the requisite movement of the master wheel a, and consequently of the
adding train moved thereby, to register the unit. On the other hand the slot 2 at
the right hand end of the plate, which is entered by the inner end of the key of
the highest denomination, is so far inclined from the vertical as that the movement
of the key therein will produce a maximum movement of the differential plate,
said movement being made to bear the same proportion to the length of movement
produced by the unit key as the denomination of said highest key bears to the unit,
so that if the unit be 5 and the highest key be 95, the movement of the differential
plate produced by the highest key will be 19 times as great as that produced by
said unit key. The return of the differential plate to its normal position after being
moved by a key is effected or assisted by means of a spring 43, the spring bringing
the plate back so that its arm g strikes a suitable stop 47 on the top plate V.
As seen in Fig. 4 the slots in the differential plate terminate in vertical portions
at both their upper and lower ends. The purpose of the vertical portions at the
lower ends of the slots is to enable the end of an operated key to fully enter its
co-operating slot in the plate before it begins to move the latter, and also to
positively bring the plate to rest before it is disengaged from it at the end of its
return stroke. The purpose of the vertical portions at the upper ends of the slots
is to cause the plate to be given its full movement and allowed to come to rest
before the key quite completes its stroke, so that any tendency of the plate to inove
too far, under its own momentum, is thereby overcome and when it has been given
its proper movement it becomes securely locked until the key begins its return
stroke. So, too, the provision for such idle movement of the keys at the ends of
their positive strokes enables them to perform other work necessary to be done
after the differential plate and parts moving with it have been given their full
movement. Thus, in a machine in which the plate actuates a type-carrier, to set
the latter to print the values of the respective keys, the excess of movement of
the key, after the carrier has been set, may be utilized to actuate the printing
devices which co-operate with the types; or where the plate actuates a register, as
in the machine illustrated in this case, such excess of movement of the keys may
be employed to operate a clutch or other connecting device between the plate and
register, as hereafter explained.
This part of my invention is not restricted in its broader scope to a differential
plate whose inclined slots terminate in vertical portions, or other straight portions
in line with the movement of the keys, for I believe myself to be the first in the
art to employ such a plate having differentially inclined slots without such

page_text: termination; and, too, such terminations may be formed at one end of the slots and
not at the other; but, for the reasons above set forth, it is highly advantageous to
provide the plate with the differential slots terminating at both ends in the vertical
or other straight portions, as shown.
I am aware that it is old in the art to combine a plurality of keys of different
values with a movable plate having a plurality of differentially inclined cam surfaces
terminating at one end with portions in line with the strokes of the keys, but in the
instances with which I am familiar such cam surfaces were not formed by slots of
substantially equal width throughout their length, as in my machine, and the plate
was liable to be thrown ahead of the key when the latter was quickly or violently
operated and thereby produce an inaccurate indication or registration. It will be
seen that in my machine there is no opportunity for independent movement of the
plate after the operated key enters its slot in the plate; as soon as an operated
key engages the plate it becomes so connected to it that thereafter the plate can
have no movement independent of the key; so that after the key has begun to
move the plate the latter is absolutely controlled by the key and the plate cannot
be thrown ahead of the key or carried too far by its own momentum.
aware of any instance in the prior art where a plurality of keys were combined
with a differentially movable plate or frame by means of any sort which would so
connect an operated key to the plate as to prevent independent movement of the
plate after it has been started by the key. Again, in the prior machines with
which I am familiar the differential cam surfaces terminated at one end in portions
in line with the strokes of the keys, but not at the other, and I am not aware of
any instance in which a plurality of keys of different values have been arranged to
actuate a differentially movable plate or frame by means of differential cam-
engaging surfaces terminating at both ends in portions in line with the strokes of
the keys, whether such cam surfaces be located upon the plate or upon the keys.
I am not
The effective operation of the differential plate E or of its ratch-bar in causing
the movement of the registering mechanism is in this instance had upon the return
movement of said plate or of its ratch-bar, preferably under the force of the
spring 43, whereby the register is not influenced by any irregular movement of the
keys, but is moved simply in consequence of the key movement but by a separate
and substantially non-varying instrumentality. The ratch-bar therefore is arranged
to move idly past the ratchet e in one direction and as soon as it reaches the limit
of movement in that direction, such limit being determined by the distance the
plate E is moved, is automatically placed in engagement with the ratchet to move
it a corresponding distance upon its return stroke.
For this purpose the ratch-bar is flexibly connected to the arm of the plate E,
in this instance pivoted to it, as seen in Fig. 8. A spring 13 bearing against the
bar may be employed to disengage the bar from the ratchet and hold them
disengaged during the stroke of the bar and plate E in one direction, but this is
not necessary, owing to the shape of the teeth upon the ratch-bar and ratchet.
When the parts are in their normal position of rest the ratch-bar is positively held
in engagement with the ratchet, and the latter and the master-wheel thereby locked
from movement, by a rotary cam 46 acting upon the ratch-bar through the medium
of a bent finger or elbow lever 45 pivoted to the frame and carrying an anti-friction
roller which bears against the ratch-bar. The shape of the cam 46 is shown in
Figs. 9 and 10 and the direction of its rotation indicated by the arrows.
It is
shown in normal position in Fig. 9, holding the ratch-bar in engagement with the
ratchet, from which it will be seen that its first forward movement will bring its
cut-away portion opposite the finger 45 and thereby release the ratch-bar and
permit the spring 13 to throw it rearward and disengage it from the ratchet, as
indicated in Fig. 10. The cam 46 is given a full revolution at each operation of
any one of the keys, through the medium of a mechanical movement hereinafter
described. It turns the first half of its revolution during the positive stroke of
the operated key and movement of the plate E and ratch-bar to the right, and the
secon half during the return stroke of the key and return movement of the plate

page_text: and bar. It results from this that after the plate and bar have been given their
full movement to the right by the operation of a key the shoulder of the cam
opposite that engaged with the finger 45 in Fig. 9 will engage said finger and
throw it forward and re-engage the ratch-bar with the ratchet. During the return
movement of the parts the enlarged portion of the cam will travel over the
finger 45 and maintain the ratch-bar in engagement with the ratchet, and will hold
them engaged when the parts come to rest, as seen in Fig. 8, thereby positively
locking the ratchet and master-wheel at the end of the return movement of the
parts and effectually preventing any overthrow of them.
No detailed description is deemed necessary of the specific form of the train of
adding wheels of this registering mechanism, as they may be varied within wide
limits, the well known Geneva movement being shown. It may be stated, however,
that each of the adding wheels of the train, excepting the first one, which is
permanently in gear with the master-wheel a, is mounted upon a swinging arm d.
The wheels are held in proper co-operative relation against the pressure of
springs a bearing against the arms d'and tending to separate them, by a cam h
engaging the left hand arm d. When this cam is disengaged from said arm the
springs a will throw the arms to the left against stops k, thereby separating the
wheels and permitting each wheel to be turned independently to indicate zero.
lieu of these springs each arm may be connected by a rod with the cam so as to
separate the adding wheels when the cam is moved for that purpose.
In
The indicating mechanism of the machine may be of the usual or any suitable
character for this class of machines, but that which I have employed embodies
novel features of construction and operation which may now be described. The
indicators consist of numbered tablets c carried upon the upper ends of vertical
reds 28, one for each key, and are adapted to be exposed to view at the usual
window in the upper part of the casing of the machine. The rods 28 are mounted
and vertically guided in two bearings, one a fixed plate of the framework through
which the stems of the tablets c loosely pass, above their junction with the rods 28,
as seen in Fig. 2, and the other a transverse plate of a swinging frame 29 hung
upon a rod 31 in rear of the rods. Each of the rods 28 is provided with a
longitudinal slot in which is pivoted a detent plate 30 which is engaged by a spring
which presses its upper end forward against a stop and projects its lower end out
of the slot and to the rear of the rod. Extending transversely across the row of
rods, in rear of the same and in position to co-operate with the spring-detents 30,
is a fixed bar 33. With the parts in the position shown in Fig. 2 it will be seen
that if one of the rods 28 be lifted its detent 30 will yield as it passes the bar 33
and then spring rearward above it, so that when the rod is released and begins to
fall the detent will catch upon the bar and support the rod in elevated position.
If the lower end of the frame 29 be then swung forward the detent will be
carried off the bar and the rod will be released and drop back to normal
position. In my present machine the swinging frame is moved by connections
with the keys themselves in such manner that upon the operation of any
key the frame will first be swung forward, to release the exposed indicator,
and then released and allowed to spring back to normal position to catch under
the detent of the newly lifted rod. The frame is swung forward by means of a
cam 75 fast upon a rotary shaft extending horizontally across the machine
beneath the rear ends of the keys, the cam being arranged to engage a friction
roller carried by a forwardly extending and depending arm 14 of the frame 29.
The shaft 71 is given a complete forward revolution at each operation of the
machine by means of a mechanical movement actuated by the keys and hereinafter
described, during which the cam will swing the lower end of the frame 29 forward,
as seen in Fig. 3, and then release it and permit it to swing by gravity back to
normal position.
It is obvious that other means than the rotary shaft and cam, actuated by the
keys, may be employed for moving the frame 29 to release the elevated rod, and
this feature of my invention, in its broader scopes, contemplates the new mode of

page_text: operation by which the elevated rods are automatically released upon the operation
of succeeding keys, and is not restricted to any particular character of connection
between the keys and swinging frame for moving the latter. Even where a rotary
shaft and cam are employed any other suitable mechanical novement for rotating
the shaft by the operation of the keys may be substituted for the one hereafter
described. So, too, it is not essential that the tablet rods be provided with
yielding detents, since the adjustment of the parts may be made such that the
detents of the rising rods will not touch the supporting bar 33, but I prefer to
employ the spring detents shown.
I am not aware of any instance in the prior art where a series of tablet rods
adapted to co-operate with a fixed supporting bar have been connected with the
operating keys by any means which would cause an elevated rod to be released
upon the operation of a succeeding key, and my invention in this respect is limited
only by the terms of my respective claims in which it is expressed.
With the keys of each bank, or as might obviously be the case with all the keys
of the machine, there is provided a key-controller F F1, Figs. 2, 6 and 11 to 16,
each consisting essentially in the present construction of a bar or frame common
to the keys of the bank and movable with them, to which the keys become attached
or coupled when displaced from normal position, and means for compelling
a full movement of said bar or frame and consequently of the operated keys; the
controller F for the dollars bank also including the single key X.
.
Inasmuch as the key-controlling devices for the two banks of keys are substan-
tially the same in construction and mode of operation, I will describe in detail
only one of them, that for the cents bank of keys, with such reference to the other
as may be necessary:
Loosely hung upon the fulcrum rod 100 of the key levers are two rearwardly-
extending rods 32, one at either side of the bank of cents keys, Figs. 2, 6, 11, 14
and 16. The rear ends of these two frames are rigidly connected by a cross-rod 35,
and their upturned forward ends, above the rod 100, are likewise rigidly connected
by a similar rod 35, the two arms 32 and the rods 35 constituting a rigid frame
hung upon the rod 100, and the rod 35 connecting the front ends of the arms and
forming a guard above the key levers to hold them to their seats on the rod 100.
The arm 32 adjacent to the side frame of the machine is longer than the opposite
arm 32 and projects rearwardly of the frame. Loosely hung between upward
extensions or ears upon the arms 32 is a swinging bar 34 provided at its lower end
with a rearwardly projecting flange 4 adapted to co-operate with hooks or recessed
lugs 3 upon the key levers A. Secured to the bar 34 at one end is a forwardly
curved pendent arm 16 carrying at its end a friction roller adapted to co-operate
with a fixed cam 17. When the parts are in their normal position of rest the
engagement of the roller with the lower portion of the cam 17 holds the lower edge
of the bar 34 swung forward and its flange 4 immediately in front of the hooks 3
upon the key levers. Whenever the front end of one of the levers is depressed.
and its rear end engages the rod 35 and lifts the swinging frame high enough to
carry the roller of the arm 16 out of the recess in the cam 17 the bar 34 will swing
rearward and its flange 4 will catch under the hook 3 of the operated key, thereby
attaching such key to the swinging frame, the engagement of the bar 34 with the
hook 3 and the upper edge of the key with the rod 35 serving to securely lock the
key to the frame, as seen in Fig. 16. (A stop pin 19 upon the side arm 32 limits
the rearward movement of the arm 16.) As the key continues its movement the
roller upon the arm 16 will travel up the curved rear edge of the cam 17 which is
so shaped so as to hold the bar 34 in positive engagement with the hook of the
operated key. Upon the return movement of the key and swinging frame
the engagement of the roller upon the arm 16 with the lower portion of the cam 17,
as the roller comes opposite the recess in the latter, will throw the lower edge of
the bar 34 forward again and disengage its flange from the hook of the key.
From the foregoing description it will be seen that each operated key becomes
coupled to the swinging frame as soon as it is displaced from normal position and

page_text: is obliged to move with the frame until it is returned to such position. By com-
bining with the swinging frame some suitable means for compelling a definite
movement of it in each direction when once displaced from normal position a like
definite movement of each operated key inay be ensured, and the novel means I
employ for this purpose may now be described :
The rearwardly projecting end of the lengthened arm 32 above referred to is
provided with a slot which embraces a friction collar upon a stud 18 projecting
laterally from the side of a vertically reciprocating rack-frame 84 mounted in
vertical guide-ways 89, Figs. 4, 6, 11, 17 and 18, this connection of the rack-frame
with the arm 35 causing the frame to be given a definite reciprocating movement
at each operation of a key. Mounted to rotate upon a fixed stud 70 between the
two racks of the rack-frame is a toothed segment 15 adapted to alternately engage
the opposite racks, and provided with a spring-tooth 6. With the parts in the
position shown in Fig. 17, if any one of the key levers be given a full positive
stroke the rack-frame will be lifted to the position shown in Fig. 18 and the left
hand rack will turn the teeth of the segment 15 in the direction of the arrow to
the position shown in Fig. 18. In reaching such position the spring-tooth 6 will
have engaged the lowerinost tooth in the right hand rack and slipped past it as
seen in Fig. 20, so that upon the return stroke of the operated key and downward
movement of the racks the right hand rack will turn the segment 15 onward in the
direction of the arrow another half revolution, at the end of which the spring-
tooth 6 will become re-engaged with the opposite rack, as seen in Fig. 17. The
segment 15 has fast upon one side of it, Fig. 20, a ratchet 36, engaged by a pawl
which prevents movement of the rack-frame and parts moving with it when they
have been started in one direction or the other. Inasmuch as each operated key is
coupled to the swinging frame, and the swinging frame is connected to and moves
with the rack-frame, it will be seen that when any key is started it will be
compelled to make a complete stroke in each direction." In order to permit a slight
initial movement of the key before it comes under the influence of its controlling
device the ratchet 36 is provided with a mutilated or plain portion 5, Fig. 20,
which normally lies under the pawl when the parts are at rest, so that a key and
the connected parts will have a very slight movement before the pawl engages the
teeth of the ratchet to compel a complete movement of the parts. The ratchet is
also preferably provided at a point diametrically opposite the portion 5 with a
second plain portion 5, of a less length than the portion 5, in order that when the
operated key is at the limit of its down stroke it and the connected parts may be
allowed slight movement before the pawl again engages the teeth of the ratchet to
compel a complete return movement of the parts.
The particular mechanical movement which I have employed for converting the
reciprocating movements of the keys into rotary movement in the ratchet forms
the subject-matter of another invention, and any other suitable mechanical move-
ment may be substituted for it in my present machine. So far as I am aware I am
the first in the art to employ a rotary ratchet and co-operating pawl as a controlling
device for the keys or other parts of a machine of this character, so that the
novelty of my invention in this respect does not depend upon the mechanical
movement employed for converting reciprocating into rotary motion.
The rotary motion derived from the reciprocation of the keys is utilized not
only in the controlling device above described, but for imparting rotary motion to
other parts of the machine for various purposes. Thus, by means of a gear 73
fast to the segment 15, and a train of intermediate gears 72 74, rotary movement
is imparted to the shaft 71 heretofore described, which, it will be remembered, has
fast upon it the cam 75 which co-operates with the swinging frame of the indicating
mechanism, Figs. 2 and 3. The gear 73 also meshes with a gear 37 which is fast
upon the same shaft and imparts rotary movement to the cam 46 heretofore
described, Figs. 8, 9 and 10. So far as I am aware I am the first to employ the
combination of a rotary shaft and a mechanical movement for giving it a complete
revolution at each operation of one of the keys in a machine of this character, and

page_text: desire to secure the same as my invention for all the purposes to which it is
applicable.
In the present machine the controlling devices above described are duplicated
for the dollars bank of keys, Figs. 4 and 6. The shaft 71, instead of extending
the entire width of the machine, is in two parts, the abutting ends of which are
confined in the bearing 60, Fig. 24, so that the two portions of the shaft will be
operated in lependently, the one portion by the movement of any key in the cent
bank Y, and the other portion by the movement of any key in the dollars bank Z
or by the single key X.
In lieu of the two independent controllers F F only one might be employed, as
indicated in Fig. 6. In this construction the controller F is common to all of the
keys in the machine, so that a key in each of the banks and the single key X may
be moved at one time and thus, by reason of their hooks 3, become coupled to the
bar 34 so as to move in unison through their entire strokes. In this case of course
only one rack-frame 84 need be used and one cam 17 for rocking the hook 4 of the
bar 34 into engagement with the hooks of the keys.
The cash register illustrated also embraces a cash drawer or receptacle, Figs. 2, 4
and 11 to 16. This drawer is located in a compartment in the lower portion of
the machine and is adapted to be positively moved outward or to its open position
for access to its contents. It is provided with a pair of side flanges 105 adapted
to rest on one or more supporting rolls 106 mounted on studs projecting into the
compartment from the side frames, and under a roll 107 mounted above the
flauges 105 near the rear of the compartment, thus forming a way for the easy
movement of the drawer in and out of its compartment, and also steadied sidewise
by steadying rolls 108 with vertical axes, also attached to the side frame of the
machine: When in its closed position, the drawer may be moved more or less to
its open position by the direct action of a cam or incline 109 connected in this
construction to and forming part of the rack-frame 84, so as to be movable
vertically therewith, the rack-frame itself, it will be remembered, being carried by
the rearwardly extended side arm 32 of the swinging key-coupler and key-
controller frane, Figs. 17 and 18. This cam or incline acts against a stud or anti-
friction roll 110 projecting from the side of the cash drawer in position to be
struck by the cam 109 upon the vertical movement of the latter, Figs. 2, 4, 11-16,
and upon the continued movement of the cam to positively move the drawer
outward from its compartment; the upper roll 107 counteracting the upward thrust
of the cam upon the drawer. The rack-frame at the opposite side of the machine
also carries a cam or incline 109, Fig. 4, bearing against another stud 110
projecting from the drawer, hence the drawer may be moved open when any key
in either of the banks is operated by the force exerted upon the key. In case a
single key-coupling and controlling frame were employed for all the keys, as in
Fig. 64, said frame might carry a cam plate 109 at each end, so that upon the
operation of any key in either set both cams would act upon the drawer to force
it open.
The cam 109 returns to its normal idle position simultaneously with the complete
movement of the key-controller and return of the key, so that when the drawer is
returned into its compartment it will meet with no obstruction; the cam 109 being
entirely out of the way, as seen in Fig. 2. It of course will be understood that so
far as this drawer-opening cam is concerned it might be connected with any other
movable part of the machine, instead of to the end of the rack-frame 84.
The drawer when in its closed position is locked in such position by a latch 111
that projects from a shaft 112, arranged widthwise of the machine, with the end of
the latch in position to fall in front of the rear wall 113 of the drawer and thus
prevent it being opened, Figs. 2, 4, 11 and 12. This latch is operated to release
the drawer by a cam 78, on the shaft 71, moving in contact with an arm 79 project-
ing from and fast to the shaft 112 so that a similar cam 78 upon the other portion
of the shaft 71 may, when it is rotated, likewise rock said shaft and raise the latch ;
the latch being thus common to both portions of the shaft 71. The adjustment of

page_text: the parts is such that when the keys are operated the cams 78 will disengage the
latch 111 from the drawer just before the cam plates 109, in their upward move-
ment, engage the rollers 110 upon the drawer, Fig. 11, so that when said plates
engage the rollers the drawer will be free to be forced open by them.
To prevent the drawer from being wholly removed from its compartment 104, it
is provided with a stop 23 projecting downward through an opening in the bottom
of the drawer from a lever 22 pivoted at 20 to the side of the drawer, Fig. 2. In
the normal position of the stop it is in position to strike the front wall of the
framework and hence prevent the entire withdrawal of the drawer from its com-
partment. The upper end of the lever 22 is provided with a finger piece 21 which,
when the drawer is open, is accessible to the attendant, and may be moved to raise
the stop 23 from engagement with the front wall of the framework and thus permit
the entire withdrawal of the drawer.
There is also provided means by which, as soon as either one of the keys has
begun its movement, all the remainder are securely locked and any independent
movement thereof prevented until the key being moved has returned to its normal
position; and while the lower edge of the differential plate E acts as a stop to
prevent the movement of a second key before the return of the first, a more efficient
device will be found desirable.
This key-locking device consists of a series of balls or sliding bolts 7, Figs. 2, 4
and 6, arranged just above the key ends within a tubular passage in the lower end
of the fixed back plate D, the guide slots in the latter extending through said
tubular passage, as shown, and the length of each bolt being equal substantially to
the distance between two contiguous keys-a bolt being provided between each
pair of keys. Each key, with the exception of the two outer ones, is thus made to
play between two of said sliding bolts 7, and the two outer keys between the fixed
abutment 8 of the back plate D and a sliding bolt. These sliding bolts are so pro-
portioned and disposed that they will completely fill the space between the two
abutments at the opposite ends of their tubular passage, less the width of one key,
so that when one key is moved the bolts will be crowded together against the
opposite abutments upon opposite sides of the moved key, and thus form a complete
barrier above the remaining keys, preventing their movement.
To hold the sliding bolts thus crowded together during the full movement of the
moved key, each of the keys are deep enough, or have extensions or keepers 9,
corresponding to the position of the bolts in an arc of a circle drawn from the axis
of the keys, so that during the full movement of a key some portion of the key or
its extension 9 is always in position to take the thrust of the bolts should there be
an attempt to move a second key before the first one is returned to its normal
position.
In the example of key-coupler shown in Fig. 64, it may be desirable to prevent
the movement of a key in one bank during the movement of a key in the other
bank, so that while the machine is adapted to couple a key in different banks to the
coupler and permit those two or more keys to move simultaneously, it is necessary
to provide for the locking of the keys in one bank during the movement of a key in
the other bank, should only one key be desired to be moved.
With the keys and the locking device, shown in Fig. 6, there is provided for each
bank of keys, see Figs. 25 and 26, a supplemental finger or keeper 105 that is
adapted to enter between either a pair of contiguous sliding bolts 7 or between the
abutment 8 and the sliding bolt. One of these fingers is in the present instance
arranged at the end of each of the banks of keys shown, and is in the form of a
lever pivoted upon the rod 100 and extending rearward, with its end adapted to
enter a slot in the fixed back plate D, and having a tendency, under the force of a
weight or spring 106, to move up into the slot and thus crowd the sliding bolts
together and prevent any key being moved in that bank. The end of the finger is
normally held out of its guide slot by the downward pressure of the key-coupler 34.
When only one key is to be moved, and a key for instance in the bank Y is moved,
its end will have so far entered between a contiguous pair of sliding bolts at the time

page_text: the key-coupler is moved that the finger 105 of that bank will be locked against move-
ment as well as the remaining keys of the bank by reason of the sliding bolte as
before described; but as soon as the coupler is raised from pressing upon the
fingers 105 the finger of the bank X in which no key has been moved will be free
to move upward under the pressure of its spring between the abutment 8 and the
sliding bolt and thereby crowd the bolts co-acting with that bank of keys together
so that all those keys will be locked against movement. Upon the return of the
key and the key-coupler 34 it will meet the raised finger of the bank of keys X and
press it back to its normal position, ready for another operation. When a key in
each bank is moved, the fingers 105 will be inactive and the remaining keys of the
banks will be locked against movement by the crowding together of the sliding
bolts co-acting with each bank as before.
This key-locking device is also made the means for locking all of the keys
against movement so long as the cash drawer or receptacle remains open; this part
of the invention including a cover movable to expose the cash drawer as well as a
drawer movable with respect to its cover or compartment, or some other movable
part of the machine which in the exigencies in the use of this class of machine it
is found desirable should be returned to its normal condition after an effective
operation. For this purpose there is provided an automatic keeper H, (see
particularly Figs. 6, 7, 14 to 16), of bell-crank form, mounted to rock in bearings
in a bracket 77, sustained by one of the cross-bars of the framework of the machine.
One arm 61 of the bell-crank extends in position to bear against the rear wall 113
of the drawer, while the other arm 62 is in position to enter one of the guide slots 1
in the fixed back plate D and pass between a sliding bolt 7 and an abutment 8, as
in Fig. 7. So long as the drawer is wholly within its compartment or in its closed
position, as in Fig. 14, its rear wall, against which the arm 61 of the keeper rests,
will hold its other arm against the pressure of a spring 10 from between the sliding
bolt and the abutment; but as soon as the drawer is moved out, as in Fig. 15, thus
taking away the support of its rear wall from the arm 61, the spring 10 will tend
to rock the bell-crank rearwardly so that its arm 62 enters the guide slot and
crowds the sliding bolts together.
To adapt the same keeper to a machine embracing two independently operated
banks of keys, as the present one, the keeper is of duplex form, so that the sliding
bolts co-operating with each bank will be simultaneously moved to lock both banks
of keys. Upon the return of the drawer to its closed position its rear wall will
strike the arm or arms 61 of the keeper, lift it and rock its other arm or arms out of
engagement with the sliding bolt or bolts and thus free the bolts so that any key
may be operated.
The automatic keeper may be rendered inactive by providing a latch 63, see
Figs. 14, 15 and 16, that may be thrown into operation to engage a projection 64
of the keeper and hold it against the pressure of the spring 10 from operating upon
the outward movement of the drawer, or when its arm 61 is not supported. The
catch 63 is hung from the key-shaft 100 and is thrown into or out of operation by
a lever 65 extending upward through an opening in the top plate B of the machine
frame, which to throw the catch into action is depressed so that a shoulder 11 on the
lever 65 will strike the under side of the top plate and be held in such engagement
by a spring 12. To release the catch the lever will be rocked slightly to free its
shoulder from the top plate and then move upward slightly to raise the catch 53, as
shown in Fig. 16.
The machine may be also provided with an alarm mechanism 1, Figs. 22 to 24,
sounded upon the operation of the keys in the different banks. This mechanism
consists of the usual bell 50, sounded by a hammer 51, having an end 52 in the.
path of movement of a cam 53 on the revoluble shaft 71. Each portion of the
shaft carries a similar cam 53 arranged adjacent the bearing 60, and the end 52 of
the bell hammer crank is widened sufficiently to be acted upon by either or both of
the cams 53, so that whichever portion of the shaft is being rotated its cam will
rock the bell-crank against a spring plunger 54 to sound the bell. The alarm

page_text: mechanism may be rendered inactive or prevented from sounding by moving an
abutment arm 55 beneath a portion of the bell-hammer, preventing its weighted
end from touching the bell, as shown in Fig. 23 and in dotted lines in Fig. 24.
This abutment arm is carried at the lower end of a vertical rod 56 extending
upward through an opening in the top plate V and provided with a thumb-wheel
by which the shaft may be rotated to place the abutment arm into or out of active
position.
The machine is also provided with a lock under the control of the proprietor, by
which the entire mechanism may be locked at any time and prevented from being
operated surreptitiously. This lock consists of a bar 102 extending the length of
the machine, see Figs. 4 and 6, beneath the top plate V, Figs. 2, 14 and 16, having
at either end depending rods 103 normally to one side of the arms 32 of the
controllers F F', but in position when the bar 102 is moved lengthwise to lie
directly above said arms and form a stop against their movement should a key in
either bank be struck. When the bar 102 is in its moved or locking position it
may be secured by a padlock not shown.
An understanding of the operation of the improved registering machine will have
been gained from the foregoing description of its construction and arrangement, but
a brief description of the various movements imparted to the mechanisin upon the
operation of a key may now be given.
The normal or idle position of the parts is shown in Figs. 1, and 4, the cash
drawer being closed and locked and the machine ready to indicate and register a
sale upon the operation of any key.
Upon the movement of a key, say the 25 cents key, its first operation will be to
pass between a pair of sliding bolts 7, crowding them in opposite directions against
the opposite abutments 8, thus locking the remaining keys against movement, and
simultaneously therewith to commence to move the key-controller F by the direct
contact of the key with the under side of its rear rod 35, thereby moving the entire
frame composed of the arms 32 and cross bars 35. This through the arm 32 imparts
a vertical reciprocation to the rack-frame 84 and thence to the ratchet 36, moving
its plain portions 5 under its pawl, and while doing so is gradually rocking the
hook 4 of the bar 34 into engagement with the hook 3 of the key by the movement
of its extension 16 from out of the recess in the cam 17. The end of the key is
also moved against the end of the tablet rod bearing the 25 cents indicator and
commences to lift said rod. Upon the reciprocation of the rack-frame rotation has
also been imparted to the shaft 71 carrying the tablet-frame rocking cam 75, the
drawer latch cam 78 and the bell hammer cam 53, and to the shaft carrying the
ratch-bar-engaging cam 46.
As soon as this has occurred the ratchet-wheel 36 has been moved far enough so
that its pawl has engaged with its teeth and thus the key is now entirely within the
control of the key-controller and must make a complete stroke in both directions.
Upon a slight further movement of the key, which has now entered its respective
slot in the differential plate E and has moved through its straight portion and is in
contact with the inclined or effective portion of the slot ready to move the plate,
and the shaft 71 continuing to revolve, the cam 78 has moved against the arm 79
of the shaft 112 and has rocked said shaft and its latch 111 from the position shown
in Fig. 2 and dotted lines Fig. 12, into the position shown in full lines in said last
named figure; thus having unlocked the drawer. The rack-frame continuing to
move vertically has also been moving the drawer-moving cam 109 connected thereto
into contact with the drawer stud 110 and as shown in Fig. 11 is acting to move
the drawer positively outward by the pressure exerted upon the key during the
further upward movement of the rack-frame. While this is occurring the cam 75
of the shaft 71 is acting against the extension 14 of the rocking tablet frame 29, as
shown in Fig. 3, so that the tablet and rod that has been previously exposed, with
its detent 30 caught by the fixed bar 33, rocked away from said bar so that it will
fall to its unexposed position by gravity; and during the further movement of the
key to the end of its stroke in one direction, the cam 75 has passed the extension 14,

page_text: allowing the tablet-frame to move by gravity to its normal position so that the
tablet which has been elevated by the movement of the key will be in position to
have its detent rest upon the fixed bar 33. During this movement of the key its
end has been acting against the inclined slot of the differential plate and has con-
sequently moved the ratch-bar fidly past the ratchet e of the registering mechanism,
and simultaneously with the key reaching the limit of its downward stroke the
ratch-bar-operating cam 46 has moved the movable finger 45 against the rear of
the ratch-bar, placing the latter in engagement with the ratchet. Also at this
time the rack-frame 84 has rotated the inutilated gear 15 to the position shown in
Fig. 18 so that its movable tooth 6 has been moved into engagement with the
teeth upon the opposite side of the frame. It should be stated that just before
reaching the limit of its movement in this direction the cam 53, as shown in
Fig. 22, has moved in contact with the arm of the bell hammer and trips the same,
sounding the alarm just as the key reaches the limit of such movement.
The key is now ready to return to its normal position, which it does by the
weight of the parts it has operated, or partly by the weight of the key-controller,
represented by the bar 34, and the power of the spring 43 which it has stored up
in moving the differential plate E. Upon this movement of the key, the parts are
allowed to return to their normal positions, the ratch-bar rotating the ratchet e,
and hence the master-wheel a of the registering mechanism, a distance equivalent
to five units of movement, so as to add 25 to the sum previously registered by that
registering mechanism; and at the completion of the return movement of the key
and the rack-frame the cam 46 will have been rotated so as to relieve the pressure
from the movable finger 45, freeing the ratch-bar from the ratchet e, and
also having returned the drawer-opening cam 109 back to its normal position, and
also the drawer-latch 111, so that in the closing movement of the drawer such
movement will not be impeded by having to return said cam to its initial position,
but will simply raise the latch by the contact of its rear wall therewith, which
after passing will be caught as in Fig. 2, and locked by the falling of the latch in
front of said rear wall.
In the opening movement of the drawer under the outward pressure exerted by
the cam 109, the arm 61 of the keeper H, Figs. 14 and 16, not being supported
by the drawer-wall 113, will fall into the position shown in Fig. 16, so that one
of its opposite ends 62, as shown in Fig. 7, will be bearing against one of the
sliding bolts 7 of the key-lock, ready to crowd the bolts to one side and enter
between this bolt and the abutment 8 as soon as the key returns to its normal
position and from between the sliding bolts, freeing the latter and allowing the
keeper to move to the position shown in Fig. 15, thus again crowding the sliding
bolts together, but above all of the keys and preventing their movement until the
drawer has been moved to its closed position, so that the keeper is moved to its
inactive position, as shown in Fig. 14.
A precisely similar movement is imparted to the devices upon the operation of
any of the keys in the bank Z, except that instead of operating the key-controller,
rack-frame, differential plate and registering plate of the cents bank Y, it will
operate the duplicate of these devices belonging to the bank Z. And in the
operation of the single key X, a similar operation of the devices will ensue, except
that instead of moving the differential plate E¹ and register B' of the dollars
bank Z, it will operate its independent register B².
In Figs. 27 to 31 there is illustrated the application of a printing attachment to
the machine herein before described, by which the various amounts indicated and
registered may be printed upon a paper record-strip, and also upon a detached
check or ticket if desired. This printing mechanism is mainly supported upon a
plate 121 secured to the left hand side of the machine. As seen in Figs. 29 and 30
the plate 121 has secured to it a bracket plate 122 in the pointed forward end of
which is mounted one end of a rod or shaft 123, whose opposite end is secured in
the plate 121. Loosely mounted upon the rod 123 are two type-wheels 124 and 125,
the former bearing upon, its periphery five type-numbers representing multiples of

page_text: one from 1 to 5, and the latter bearing a series of type-numbers in multiples of
five from 5 to 95 inclusive, and in this instance also a zero type. Each type-wheel
consists of a thin circular disk 29, and a band or flange secured to or formed
integral with it and upon whose surface are formed or secured the type-numbers.
Secured to the hub of the wheel 124 is a beveled gear 126 which meshes with a
beveled gear 127 fast upon a rod 128 journalled near its rear end in the cross piece of
the bracket 122 and having its extreme forward end journalled in a fixed collar 129
surrounding the rod 123 between the gear 126 and the forward extension of the
bracket 122. The type-wheel 125 has fast to its hub a similar beveled gear 130
which meshes with a beveled gear 131 fast upon a shaft 132, Figs. 28 and 30,
said shaft 132 being journalled in the bracket 122 and in a second fixed collar 133
between the beveled gear 130 and the right hand flange of the plate 122 by which
the latter is secured to the plate 121, Fig. 30. The shaft 132 has fast upon its
rear end, Fig. 28, a pinion 134 which meshes with a rack 135, Fig. 29, whose left
hand end is pivoted to the differential plate E, and the adjustment of the parts is
such that whenever any key is operated the movement given the plate E will be
transmitted to the type-wheel 125 and the latter turned to bring to the printing
point a number corresponding to the value of such key. The shaft 128 has fast
upon its rear end a pinion 137, Figs. 28 and 29, which meshes with a rack 138
whose left hand end is pivoted to the right hand end of a link 139, Fig. 28, which
link is pivoted at its left hand end to the differential plate E', so that upon the
operation of any key in the dollar bank the movement imparted to the plate E'
will be transmitted to the type-wheel 124 and the latter turned to bring to the
printing point the number corresponding to the value of such key.
The platen which co-operates with the type-wheels, the means for advancing the
paper strip, and the means for moving the inking ribbon, are all actuated by
the rotary shaft 71 heretofore described. This shaft has secured upon its extreme
left hand end, outside the frame and plate 121, Fig. 29, two cams 140 141, the
former of which is adapted to co-operate with an anti-friction roller 142 mounted
upon the lower rear end of a link 143 which is pivoted near said end to the lower
forward end of an arm 144 loosely hung to a support upon the plate 121 at 145.
The upper forward end of the link 143 is pivoted to an ear 146 upon a vertical
arm or plate 147 which is pivoted at its lower end to a suitable support 148 upon
the plate 121. A spring 149 coiled around the support 148 of the arm 147 and
bearing against a pin upon the plate 121 presses the arm 147 rearward, its movement
in that direction being limited by a stop 150 upon the plate 121. Secured to a
shoulder or ledge upon the inner side of the arm 147 is an arm 151, in this
instance composed of a series of thin spring plates, which projects rearward at a
right angle to the arm 147 and carries at its rear end a platen 152 immediately
above and adapted to co-operate with the two type-wheels 124 and 125. When
the front end of a key lever is depressed and the shaft 71 given a half revolution
in a forward direction its cam 140 rides under the collar 142 on the link 143 and
moves the latter upward and forward, tilting the arm 147 and the platen-arm and
platen to the positions indicated by the dotted lines, against the stress of the
spring 149. Just as the operated key completes its downward stroke the cam 140
clears the roller 142 and the spring 149 throws the parts back to normal position,
the arm 147 being arrested by the stop 150 and the resiliency of the platen-arm 151
permitting the momentum of the parts to throw the platen 152 against the type-
wheels. A horizontal plate 153, having an upwardly curved rear end, is secured
at its inner edge to the plate 121 and extends over the type-wheels. It is provided
with an opening at 154, immediately above the type-wheels, through which the
platen 152 may pass.
The supply of the paper record-strip 155 is carried upon a spool 156 mounted
upon a stud 157, whence the strip is led forward beneath a guide 158, thence
beneath the platen 152, thence forward around a guide-roller 159 loosely mounted
upon a stud 160, thence downward between a pair of feed-rollers 161 and 162, and
thence around a storage-spool 163 mounted upon a stud 164. The shaft 71 has fast

page_text: upon it beside the cams 140 and 141 a grooved wheel or disk 165, and the storage-
spool 163 has fast upon it a similar, though larger, grooved wheel 166. A yielding
cord or band 167 passed around these two grooved wheels serves to transmit
movement from the shaft 71 to the storage-spool 163, to cause the latter to wind up
the length of paper strip 155 advanced to it by the rollers 161 and 162 at each
operation of the machine, the yielding character of the cord or band 167 permitting
it to slip upon the grooved driving wheel 165 when the storage-spool 163 has been
turned far enough to wind up the slack in the strip; as will be readily understood.
The feed-rollers 161 and 162 are driven by a train of gearing from the shaft 71, the
latter having fast upon it a pinion 168 which meshes with a large gear wheel 169
which latter has secured to its side a pinion 170 which meshes with a large gear
wheel 171, which latter in turn meshes with a loose pinion 172 which in turn
meshes with a large gear wheel 173. The wheel 173 has fastened to it the
feed-roller 161 and also a toothed wheel 174, which latter meshes with a toothed
wheel 175 fast upon the feed-roller 162. The roller 162 is carried by a swinging
arm 176 hung to a pivotal support 177 near its upper end and pressed rearward by
a spring 178 to hold the roller 162 against the roller 161.
An endless inking ribbon 176 is passed around guide-rollers 180, 181 and 182 at
three corners of a square, and between a pair of feed-rollers 183 and 184 at
the other corner of the square. The roller 183 is fast upon the gear 171 above
referred to and the roller 184 is mounted in a swinging arm 185 and pressed by a
spring 186 against the roller 183 and the movement imparted to the gear 171 from
the shaft 71 causes the rollers 183 and 184 to advance the inking ribbon at each
operation of the machine, to present a fresh inking surface at the printing point.
The guide-roller 182 is carried by an arm 187 which is pressed by a spring 188
downward and rearward to hold the inking ribbon taut. The inking ribbon may be
of the ordinary character, and be removed and a new one applied whenever it has
become so used or dry as to print imperfectly; but I have provided means for
automatically inking the ribbon and keeping it in fresh condition. Secured to the
upper end of a bracket plate 189, above the inking ribbon in its passage from the
feed-rollers 183 and 184 to the tension roller 182, an ink-well 190, in this instance
of hopper form and having a series of strips of felt 191 secured in its lower
contracted end, with their lower ends depending from it and bearing against the
inking ribbon. A supply of ink is kept in the well 190 and transmitted by the
strips of felt to the inking ribbon as the latter is drawn across the former.
For the purpose of automatically locking the type-wheels in position while the
printing is being effected I have provided a pair of locking arms or dogs 192
and 193 pivoted at their rear ends to the opposite sides of a plate 194 projecting
rearward from the bracket plate 122 heretofore described, Figs. 29 to 31. These
armış have secured between them, below and in front of the plate 194, a block 195,
so that said arms and said block constitute a rigid frame hung to the plate 194.
The forward ends of the arms 192 and 193 are bent inward toward each other so
that their toothed ends may co-operate with toothed locking wheels 196 secured to
the hubs of the respective type-wheels, Fig. 29, these toothed wheels lying within
the vertical planes of the sides off the type-wheels, and the bent ends of the
arms 192 and 193 permitting their locking teeth to engage the toothed wheels.
The block 195 has upon its lower side a tubular housing 197 in which is confined a
spring plunger 198 whose lower end rests upon the periphery of the cam-disk 141.
During the downward stroke of an operated key and forward half of the revolution
of the shaft 71 the cam 141 will ride under the spring-plunger 198 just at the end
of such half revolution and throw the arms 192 and 193 upward and engage their
teeth with the teeth of the wheels 196 and hold the type-wheels locked in their
adjusted positions while the printing is being effected, after which, at the beginning
of the return stroke of the operated key and second half of the revolution of the
shaft. 71, the cam 141 will clear the lower end of the spring-plunger 198 and the
arms 192 and 193 will drop to normal position and release the type-wheels.
The record-strip supply-spool before referred to has secured to it a grooved disk

page_text: or wheel 199 with which co-operates a brake arm 200 pressed against it by a
spring 201, to preserve the proper tension upon the strip.
From the foregoing description it will be seen that when the front end of any
key lever is depressed its rear end enters the corresponding slot in the differential
plate, moves said plate the proper distance in one direction as it travels through
the inclined portion of the slot, thereby turning the type-wheel until the number
representing the value of the key is brought to the printing point, and then
during the further idle movement of the key, in the vertical upper end of the
slot, the locking dogs are thrown into engagement with the toothed locking
wheels, to lock the operated type-wheel in its adjusted position, and the platen
is retracted, against the stress of its spring, and then released and thrown
against the type-wheels to effect the printing; and that after this has been
done, during the first downward movement of the rear end of the operated key,
through the vertical upper end of its slot, the locking dogs will be disengaged from
the type-wheels and the latter released, and then during the return of the key
through the inclined portion of its slot the differential plate will be returned to
normal position and carry the operated type-wheel with it to such position, after
which the rear end of the key will pass downward through the vertical lower end
of its slot and be disengaged from the differential plate. The provision for idle
movement of the operated key (with respect to the differential plate) at the end of
its positive stroke, is particularly important, since it enables the type-wheel to be
turned to proper position and then come fully to rest before it is locked in such
position and before the platen is actuated to effect the printing. Under the
construction illustrated the provision for this idle movement is made by terminating
the inclined slots in vertical portions at their upper ends, but provision for such
movement may be made in various other ways in machines employing differentially
movable plates or frames of a different character from that employed in the
present machine; and the invention in this respect is not restricted to the employ-
iment of a differentially movable plate having inclined slots, nor to an endwise
moving plate or frame, or a plate or frame which slides in and upon guide ways,
but, in its broader scope, contemplates, in the combinations set forth in the claims,
all forms and arrangements of differentially movable plates or frames employed to
set a type-wheel or carrier and actuated by the keys in such manner as to be
given their proper movement, proportionate to the values of the keys, by less
than the full positive strokes of the keys, for the purpose described.
In the indicating mechanism heretofore described the indicators are lifted to
indicating position directly by the positive strokes of the keys and are caught and
temporarily held in indicating position by the engagement of their detents with the
supporting bar. In Figs. 32 to 38 there is shown a modified form of indicating
mechanism in which the indicators are not lifted directly by the positive strokes of
the keys, but are simply set by such strokes in position to be subsequently moved
to indicating position upon the return or negative strokes of the keys. This
modified form of the indicating mechanism may now be described as follows: the
indicators c are carried upon the upper ends of vertical plates or supports 202
passed through and closely fitting guide apertures 203 in a transverse guide
plate 204. The lower ends of the supports 202 pass through and are confined in
the transverse portions of T-shaped apertures 205 in a second transverse guide
plate 206 beneath the plate 204. About midway of its length the indicator-
support 202 is provided with a housing 27 in which is fitted the upper end of a
narrow plate 208 which normally rests in vertical position in the longitudinal
slot in the lower half of the indicator-support. A spring 209, Fig. 38, bearing
against the forward side of the upper end of the plate 208 yieldingly holds the plate
in normal vertical position with its upper end bearing against a cross pin in the
housing 207. The movement of the plate in the opposite direction is limited by a
second cross pin 210, Fig. 38.
The rear ends of the key levers B have secured to or formed upon them
,housings 211, Fig. 35, in bores in which are rods or plungers 212 surrounded by

page_text: springs 213 which press them rearward and project their ends from the housings 211.
When the keys are at rest their rear ends stand immediately in front of the lower
ends of the indicator supports 202. When the front end of a key lever is depressed
its rear end swings upward in the arc of a circle and its spring-pressed rod 212
engages the pivoted plate 208 of the corresponding indicator-support. The strength
of the spring 213 which holds the rod 212 in its rearmost position is sufficient to
overcome the resistance of the spring 209 which holds the plate 208 in its normal
position, and consequently the engagement of the rod 212 with the plate 208 will
tend to force the latter rearward to the position of the right hand one in Fig. 33,
the shape of the guide-slots 205 permitting such movement of the plate 208 at
the proper time. When moved to this position the end of the plate 208 will stand
in the path of travel of a vertically reciprocating lifting device, by which the
indicator is lifted into indicating position, which may now be described :
This lifting device consists primarily of a transverse horizontal plate or frame 214
extending across the rear sides of all the indicator-supports, beneath the lower guide-
plate 205, and having secured to or formed upon its opposite ends vertical extensions
or plates 215. which are confined and adapted to slide vertically in guide-ways upon
the inner surfaces of the vertical frame plates 216. The lifting plate 214 is provided
along its forward edge with an upwardly projecting flange, Fig. 34, for a purpose
hereafter explained, and in this instance also has an upwardly projecting flange
along its rear edge.
By means hereafter described the lifter 214 is given a complete reciprocating
movement in opposite directions at each operation of the machine, being moved
during the downward or positive stroke of the front end of the key lever from its
upper position shown in Fig. 32 to its lower position shown in Fig. 33, and then
returned to its upper position during the return upward stroke of the front end of
the key levers. Keeping this movement of the lifter plate or frame in mind, it will
be seen that, starting with the parts in the position shown in Fig. 32, when the
front end of a key lever is depressed and its rear end thereby lifted its spring-
plunger 212 will bear against the plate 208 of the corresponding indicator-support
and tend to force the lower end of such plate rearward to the position shown in
the case of the right hand one in Fig. 33, as before explained. The downward
movement of the lifter-frame 214, adjacent to the rear sides of the indicator-
supports and plate 208, will, however, prevent movement of the plate 208 to such
position until the lifter passes below the lower end of said plate; during the
downward movement of the lifter, therefore, and upward movement of the rear end
of the key lever, the rod 212 of the lever will press the plate 208 rearward as far
as the position of the lifter will permit, after which, in the further upward move-
ment of the rear end of the lever, its rod 212 will be forced into its housing and
its spring 213 be put under tension. As soon as the lifter passes below the lower
end of the plate 208 the spring 213 will force the rod 212 rearward, out of its
housing, and throw the plate 208 to the position of the right hand one in Fig. 33,
where its lower end will stand immediately above the lifter 214.
Upon the
return upward stroke of the front end of the operated key lever, and upward
movement of the lifter 214, the latter will catch the plate 208 which has been
moved rearward and lift its indicator-support and indicator to the position of the
right hand one in Fig. 32, and thereby expose the indicator to view at the usual
window in the casing of the machine.
It will be understood that at the downward movement of the lifter 214, during
the positive stroke of the operated key, any indicator which has been sustained in
elevated position by the lifter, as the right hand one in Fig. 32, will be released
and drop back to normal position with the lifter, the spring 209, Fig. 38,
throwing the plate 208 back to normal position in its slot in the indicator-support
as soon as the flange upon the front edge of the lifter clears its lower end.
From the foregoing description it will be seen that at each operation of a key
lever the lifter is lowered and any exposed indicators withdrawn from view, during
the positive movement of the key lever, and the plate 208 of the indicator
C

page_text: corresponding to the operated key is set for engagement with the lifter, and then
upon the return negative stroke of the key and upward movement of the lifter the
latter engages such plate and lifts the indicator into exposed position.
The means for giving the lifter its vertical reciprocating movements may now be
described. To ears 217 projecting forward from the rear side of the lifter 214 near
its opposite ends are pivoted the upper ends of links 218 which are pivoted at their
lower ends to crank arms 219 fast upon short shafts 220 journalled in suitable
bearings upon the framework and having fast upon their forward ends beveled
gears 221 which mesh with beveled gears 222 fast upon the rotary shaft 71
beretofore described. At each complete revolution of said shaft the crank
arms 219 are given a complete revolution, and the lifter 214 is lowered to its
lowest position during the first half of their revolution and returned to its upper
position during the second half of the same. The first half of the revolution of the
shaft 71 and parts geared to it is accomplished during the positive stroke of the
For the purpose of
operated key, and the second during its negative stroke.
partially balancing the weight of the lifter 214 there is provided in this instance a
spring-pressed bent lever 223 pivoted to the framework at 224 and provided at its
upper end with an anti-friction roller bearing against the under side of the
lifter 214. The short arm 225 of the lever, below its pivotal point 224, is engaged
by a rod 226 confined in a housing 227 and pressed outward by a spring coiled
around it. This spring presses the outer end of the lever 223 forward with
sufficient force to support the weight of the lifter, while the application of the
spring to the lifter is such that the complete depression of the outer end of the lifter
will only slightly compress the spring, so that the lever is substantially equally
balanced throughout its limit of movement.
Any suitable mechanism intermediate the keys and lifter frame may be employed
for giving the latter its reciprocating movement, and it is not essential that it be
actuated by a rotary driving shaft.
The method of engaging the indicator-supports with the lifter may also be
widely varied without departing from my invention. Thus, it is not essential
that the indicator-supports shall be limited to a straight reciprocating movement
and be provided with the pivoted catch plates adapted to be thrown into the
path of the lifter, but on the contrary the indicator-supports themselves may be
arranged to be swung bodily into and out of the path of the lifter. Thus,
in Figs. 36 and 37 there is shown a modified form of indicator-support, consisting
simply of a vertical rod or plate 228 passed through a guide aperture 229 in the
plate 205, which is sufficiently large to permit the lower end of the support 228
to be swung backward and forward. The support 228 has secured to it near its
lower end a curved spring 230 whose outer end extends through the guide
aperture 209 and when the indicator-support is in its lower position serves
hold its lower end in forward normal position. Under this construction, when
the front end of the key-lever is depressed the spring 212 carried by its rear
end engages the forward side of the lower end of the indicator-support and
forces the latter rearward as far as the position of the descending lifter 214
will permit, and as soon as the lifter clears the lower end of the support the
latter will be thrown further rearward, to its limit of movement, and will stand
in the path of the lifter, so that upon the return upward movement of the latter
it will carry the indicator to exposed position. Upon the succeeding positive
stroke of a key and lowering of the lifter-frame 214 the elevated indicator-
support will move downward with it, and as it approaches its lower position its
spring 230 will throw its lower end forward into line with the other supports.
to
From the foregoing description it will be understood that the mode of
operation of this indicating mechanism consists in "setting" the proper indicator
by the positive stroke of the key, and then moving it into indicating position
by independent means, in this instance during the return or negative stroke of
the key. The indicators therefore are not exposed to view until the key has
made its return stroke and performed all of its duties. At each operation of the

page_text: machine, also, the previously exposed indicator is released and withdrawn from
view during the positive stroke of the key, so that at the end of the operation
only the indicator corresponding to the newly operated key is exposed to view.
