Improvements in Typewriting and Adding Machines.
T, WILLARD LE GRAND BUNDY, of Binghamton, in the County of Broome, State
of New York, United States of America, Machinist, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
My invention relates to that class of machines in which type are carried upon
discs or wheels, or other suitable type-carrying mechanism, and are brought upon
a printing or adding line by the manipulation of keys for the purpose of printing
therefrom or to disclose the total sum of the numbers added. It has for its object
to increase the efficiency of such machines, to decrease the number of keys required
to operate the discs or wheels or other type-carrying mechanism, and generally
to simplify and improve the construction and operation of such machines, and it
consists of the devices herein shown and described.
Heretofore it has generally been found necessary in machines of the kind to
which my invention relates, to employ a large number of keys and wheels, to com-
mence the type-setting or the adding at the units place, proceeding thence to the
left to higher orders in regular sequence. By means of my improved device only
ten type-setting keys, which will hereafter be designated as type keys, are needed,
no matter how large the numbers to be printed or added, and the type-setting and
adding are begun at the highest order of figures in the number to be printed or
added and proceed to the right in the normal manner of reading numbers; only
one series of adding wheels is required and the adding may begin upon any adding
wheel representing any order of figures, such wheel adding and carrying to the
left without affecting any of the adding wheels to its right, representing lower
orders of figures.
My improved device may be used either as a printing or recording machine alone,
as for example for the purpose of setting type to print the amounts of a pay roll,
or as an adding machine alone, or as both combined; in the latter case the machine
is manipulated by the same set of keys used for either of the separate purposes
alone.
are
The general operation of certain parts of the preferred form of my device is as
follows. The ten type keys 15, 15, represent the digits from 0 to 9 inclusive. By
depressing any one of these type keys, one of a series of type-carrying mechanism,
as shown in the drawings type-carrying dises 5, is rotated so as to bring upon a print-
ing line or lines type representing the number of the type key depressed. In the
form shown in the drawings, these type-carrying discs carry two sets of type 6
and 7, each set being the duplicate of the other. One set, 6,
brought upon a printing line at the top of the machine, as shown in
Fig. 3, for the purpose of printing preferably upon a removable piece of paper.
For this purpose an inking ribbon, 73, see Fig. 5, and impression mechanism
actuated by the handle 42, Fig. 1, are provided. The other set, 7, are brought
opposite a platen 78 and by means of an inking ribbon 85 print upon a permanent
recording strip 82 within the interior of the machine. The two records, as far as
concerns the matter printed by the type of the discs, are of course exact duplicates.

page_text: By mechanism hereafter to be described, a series of adding wheels 106, see Fig. 5,
are rotated as the type keys 15 are depressed, the number represented by any type
key, depressed, being added by the adding wheels, the total of the numbers added
being visible at all times through an opening 116 in the casing 115 of the machine
and, if desired, the total may at any time be printed upon a piece of paper by means
of mechanism hereafter to be described.
In depressing the type keys to print or add any number, the type key, represent-
ing the figure of highest order or value in the said number, is first depressed, then
the type key representing the figure of next lower order and so on. Thus to print
or add $75.95 that one of the type keys 15, which bears the number 7 is first
depressed, then the one bearing the number 5, then 9 and then 5 again.
By means of a finger or presser, in the drawings shown as presser 22, intervening
between the type keys and the type-carrying mechanism and adapted to be operated
by each of the type keys and when operated by said keys to actuate successively
the type-carrying mechanism, the type represented by the type-key or keys struck
are brought upon a printing or adding line. I am thus enabled to dispense with
the large number of type-keys heretofore necessary in machines of this character
and to operate my machine by means of ten type-keys. In my preferred form,
shown in the drawings, the presser travels in order to register successively with the
different type-carrying mechanism, but this travel on the part of the presser is not
essential to my invention as any suitable means may be employed for causing the
presser and different type-carrying mechanism to register successively with one
another, as for example by the travelling of the type-carrying mechanism, instead
of the presser, to cause the former successively to register with the presser.
The drawings, which form part hereof, represent the preferred form of my
improved device, which I will now proceed to describe.

handle and certain connecting mechanism removed; Fig. 3 is a front elevation with
the face plate and certain parts removed; Fig. 4 is a sectional plan, viewed from the

the type-carrying discs; Fig. 9 is a perspective view of one of said discs; Fig. 10
is a detail view of the adding wheels and their carrying mechanisın, and Fig. 11
is a detail view of part of the inking mechanism. Figures 12 and 13 show details
in plan and side elevation respectively of the adding and sum-printing mechanism.
I is the casing of my improved machine. 2 is an upward extension of the casing
to hold the handle 42 and connections and parts of the impression mechanism.
The type-carrying mechanism for carrying and bringing the type upon the
printing or adding line, are represented in the drawings as type-bearing discs or
wheels. Other suitable forms of type-carrying mechanism may, however, be
employed if desired. These discs or wheels consist of the type-carrying discs 5
and adding wheels 106.
3 are levers for operating the type-carrying discs and adding wheels and for the
sake of brevity they will be hereafter designated as operating levers. There are five
of these operating levers as shown in the drawings, but a greater or smaller number
may be employed as desired. They and the type discs and adding wheels represent
the different orders of figures in the numbers to be printed or added. Rods 4,
pivoted to the operating levers, and to the type-carrying discs 5, connect the said
levers and discs together. Each of the discs 5 has upon its periphery two sets of
type, 6, 7, each set representing digits 0 to 9 inclusive and both sets being exactly
alike. When an operating lever 3 is depressed, its corresponding type-carrying
disc 5 is rotated so as to bring one of the digits in the set of type, 6, upon the print-
ing line at the top of the machine and the same digit in the other set 7 upon the

page_text: printing line opposite to platen 78. The particular digit which is thus brought
upon the printing lines, depends upon the length of throw of the operating lever 3
and arm 4 and the consequent extent of rotation of the disc 5. This is under the
control of the operator as will be hereafter described. Pin 8 projecting into slot 9
in said discs acts as a stop to prevent excessive rotation of the discs.
Type-carrying discs 5 have also upon another portion of their peripheries a
series of teeth 10. Into these take pawls 11 for the purpose of locking the discs in any
particular position against the action of springs 14, Fig. 5, which tend to raise
operating levers 3 and rotate type-carrying discs 5 into their normal position.
Each pawl 11 is pivoted at its centre 12, see Fig. 3, and is normally pressed into
contact with teeth 10 by means of springs 13. After a disc has been rotated so
as to bring any digit upon the printing lines, it is held locked in that position by
one of the pawls 11 until these pawls are removed from contact with teeth 10 in
any one of the manners hereafter described.
The type keys 15 for operating levers 3 are ten in number and each one bears a
number, the numbers running from 0 to 9 inclusive, as shown in Fig. 2. In
addition to these there is another key, 15", which will hereafter be spoken of as the
spacing key; it bears no number and its function and mode of operation will be
hereafter described. These type keys 15 and spacing key 15" have each a shank 16,
see Fig. 1, a hook 17 and a projection 32. 18 is a rocking bar supported by arms 19
on each side of the machine, the latter being pivoted to the framework at 20, see
Fig. 4. This rocking bar will hereafter be spoken of as the key bar. The shanks 16
of any of the keys 15 and 15", when the latter are depressed (shown by dotted lines
in Fig. 7), strike against and force down key bar 18, the hook 17 catching under
the key bar.
21 is a movable carriage. It is mounted upon the rear part of key bar 18.
approximately near the centre of the latter, and the two are adjustably secured
together by means of slots in the carriage and a pin, projecting from the key bar,
and the axle of star wheel 24 and gear wheel 27, the pin and axle passing through
the slots as shown in Figs. 4 and 6. By means of these connections, movable
carriage 21 can be moved sidewise, to the right or left, along key bar 18.
Movable carriage 21 carries a presser 22, preferably a traveling presser, and an
index finger 23. The former projects over the ends of operating levers 3 and when
key bar 18 is depressed by any of the type keys 15, the presser 22 strikes and
presses down, one of the operating levers 3, whichever one of the said levers it
happens to be over at the time.
Motion sidewise is imparted to the carriage, 21, by the following mechanism.
A star wheel 24 is secured to key bar 18 and is prevented from backward rotation
by a spring-pressed pawl 25. This star wheel engages with a hook 26, secured to
the framework of the machine, and each time the star wheel rises one of its teeth
strikes against the hook and this rotates the star wheel one tooth. To the star
wheel is secured a gear wheel 27, the latter rotating with the former, and driving
carriage 21 to the right through the engagement of gear 27 with the teeth of
rack 28, which latter is fastened to carriage 21. Each time key-bar 18 is depressed
by any one of the keys, the star wheel rotates one tooth and carriage 21, presser 22
and index finger 23 move one point to the right, thus bringing presser 22 over the
next operating lever, 3, to the right. One portion of gear wheel 27 has no teeth,
as shown in Figs. 4 and 6. This portion is so arranged that it will register with
rack 28 just as the presser and index finger rise after they have been depressed
in their position at the extreme right, or in the unit position. As in this portion
of gear 27 there are no teeth to catch into the teeth of rack 28, spring 29 at once
hauls carriage 21, with presser 22, and index finger 23 back to their original
positions, ready for another operation of the machine.
Thus by depressing any one of the type keys 15 a sufficient distance, key-bar 18
will be depressed carrying with it carriage 21, star wheel 24 and presser 22, the
latter forcing down one of the operating levers 3, and thereby rotating its corre-
sponding type carrying disc 5, until one of its digits is brought upon both printing

page_text: lines at which point the type-carrying disc will be held locked by its pawl 11;
star wheel 24 being rotated one tooth-upon its subsequent upward movement thus
moving presser 22 to the right over the next operating lever in order. If another
type key 15 is then depressed, the said next operating lever 3 will be moved in the
same manner and so on, the presser 22 moving one point to the right at each
depression of a key until it stands over the unit operating lever. At the next
depression of a key, the presser after depressing the said unit operating lever will
be at once returned to its normal position at the extreme left of its range of move-
ment, ready for the printing or adding of the next number.
The object of the spacing key 15 is to cause carriage 21 and the presser 22 to
move to the right without however operating the presser 22 until the presser is over
the proper lever to begin the printing. For this purpose the throw of spacing
key 15 is not long enough to cause the presser 22 to reach any of the operating
levers 3. It is long enough, however, to depress key bar 18 sufficiently to bring
star wheel 24 below hook 26 and thus to rotate the star wheel 24 and move
carriage 21 and presser 22 one point to the right. The operation is as follows.
Spacing key 15* is pressed down once, twice or more times until
presser 22 stands over the operating lever representing the order of
figures corresponding with the figure of the highest order or value in
the number to be printed or added. Thus for instance, if it is desired to print or
add the number 765, spacing key 15 would, with five operating levers, as shown
in the drawings, be operated twice, then the type key 15, bearing the number 7
would be operated, then the type keys 15 bearing the number 6, and 5 would be
successively depressed. Any one of the type keys 15 can thus by means of spacing
key 15 and presser 22 be made to set its number for printing at any order of
figures, either the units' order, or the tens, or the hundreds, or at any order desired.
In order to ensure that each type key 15 shall bring upon the printing lines its
proper figure, borne upon the type-carrying discs, and no other figure, I have
devised the following mechanism. The type keys are so arranged, see Figs. 1
and 7, that each has a different throw from every other type key and thus when
fully depressed each type key will bring upon the printing lines a different figure
(its own appropriate number) from that of every other type key, when fully
depressed. Frame 30° acts as a stop to prevent the key from being depressed too
far.
After any key has been partly depressed, it can not be released or raised and no
other key can be operated until the first mentioned key has been depressed to its
fullest extent. This is accomplished by means of a locking rack and pawl, one
secured to the framework of the machine and the other connected with the type-
key or the key-bar 18, so that as key-bar 18 is depressed by a key, it and the key
will be restrained from upward movement and no other key can be operated, until
the full stroke of the key is made, when the key or key bar will cause the pawl to
be disengaged from the rack, whereupon the parts will be returned to their original
positions and any key will be free to operate. My preferred form of such locking
devices will now be described.
.
Shelf 30 is pivoted along one edge, its free edge being normally raised by spring 31
as shown in Fig. 7. When a key is depressed, its projection 32 strikes the free
edge of 30, depresses the shelf and forces it against sliding piece 33. The latter
piece has in it inclined slots 35 through which pass pins 34 loosely securing it to
rack 38, fastened to the framework of the machine. 36 is a friction piece pressing
sliding piece 33 against rack 38 so that the former will stay in whatever position
it is placed. 37 is a pawl secured to arm 19. When key bar 18 is depressed by
a key, pawl 37, through its engagement with rack 38, will prevent the key bar 18
from rising again, and the latter through the engagement of hook 17 with it will
prevent the key from being raised. By the time each key has made its full stroke,
however, projection 32 depresses shelf 30, and sliding piece 33; the latter in its
downward movement moves forward, frees pawl 37 from rack 38 and permits

page_text: springs 19 to raise arm 19, key bar 18 and the key that has been depressed. The
next key in order may now be operated.
A groove or depression 39, Fig. 2, is made in the top of the machine alongside
of the type 6 on the type-carrying dises for the insertion of other
type or printing matter. As shown in the drawings, Fig. 1, a type form
carriage 39 is inserted in this groove, provided with a type form 40, containing for
example a list of the names, or numbers or both, for a pay roll opposite to which
the amounts of the different salaries are to be printed by the type, 6, on the type-
carrying discs. 41 is a rack secured to carriage 39 and moving in slot 41" for the
purpose of imparting intermittent motion to the carriage through a tooth 55 of
oscillating arm 54, Fig. 4, in a manner presently to be described.
The impression mechanism, shown in the drawings, for causing an imprint to
be taken of the type 6, upon the type-carrying discs and the type 40 on carriage 39,
is as follows. A handle 42, Fig. 1, having a can surface 43 is pivoted in part 2
of the framework, 44 is a shaft working loosely inside of frame 2 and carrying a
platen holder 45 and having a recess for receiving one end of lever 47, see Fig. 5.
Platen surfaces 46, 46, 46, Fig. 3, each having a different width are securely held
by platen holder 45 but are adapted to be turned so as to bring any one of said
platen surfaces above the printing line. Any suitable means can be employed for
turning these surfaces or for securing them in position. In the construction shown
in the drawings, printing surfaces are arranged upon a common axle which is
mounted in bearings in the platen holder, and they are secured in position by means
of tightening screws 46d. If it is desired at any time to change the width of the
platen surface in use, the screws are unloosed and the platen surfaces are turned
until the proper one is in position, when the screws are again tightened. The wider
platen surfaces are intended to be used where more than a single line is to be
printed at one time.
Lever 47 is pivoted in framework 2; its upper arm projects into a recess in
shaft 44 while its lower arm projects downward into the interior of the frame 1.
Its object is to impart motion to various parts of the interior mechanism of the
machine, viz., the mechanism for feeding forward carriage 39, for releasing the
type-carrying discs by withdrawing pawls 11, and for actuating the platen and
feeding the inking ribbon and paper strip of the impression mechanism in the
interior of the machine. These are accomplished by the following described
mechanism.
Spring 48 keeps lever 47 normally in the position shown in Fig. 5. The lower
arm of lever 47 bears against the three-armed lever 49 and lever 75, Fig. 4. When
handle 42 is pulled downward, the lower end of lever 47 is forced toward the back
of the machine against the pressure of spring 48, pushing back levers 49 and 75.
When handle 42 is raised, spring 48 forces lever 47 forward and with it levers 49
and 75.
The middle arm of lever 49 imparts motion to the devices for feeding forward
carriage 39 and for releasing the type-carrying discs. 50 is a three-sided cam
piece for regulating the extent of throw of lever 49. It is mounted upon pin 50"
to which is also secured index finger 50b, Fig. 2, by which the cam is shifted from
one to another of its three positions. The three sides of the cam when turned
successively toward the middle arm of lever 49, lie at different distances from that
arm, thus permitting carriage 39 to be fed a short or longer distance as desired.
50 is a rod pivotally connected to the end of the middle arm of lever 49 and to
rod 51 mounted on shaft 52. Springs 53 tend to retract shaft 52. 54 is an oscillat-
ing arm mounted on shaft 52 and having a tooth 55 adapted to take into the teeth
of rack 41. As lever 49 is moved backward and forward by the operation of
handle 42, shaft 52 and arm 54 are rocked back and forth and tooth 55 inter-
niittently feeds forward rack 41 and carriage 39.
Shaft 52 has also another arm 56 secured to it, carrying pin 57. This pin engages
with pin 58 on lever 59, pivoted at 60. The further end 61, of the lever 59, is
:

page_text: adapted to bear upon a swinging arm 63 (when operated against the pressure of
spring 62) and arm 63 is adapted to press upon the upper end of pawls 11 to
release the type-bearing discs 5. In one part of its rocking motion pin 57 of
arm 56 presses against pin 58 and thereby forces arm 61 of lever 59 against swing-
ing arm 63 and the latter against pawls 11 to free them from engagement with the
type-carrying discs. Thus at each operation of the handle the type-carrying discs 5
and operating levers 3 are released, and through the operation of springs 14 are
returned to their normal positions.
64 Fig. 3 is a lever projecting through the top plate of the machine adapted to
be operated by hand and pivoted so that its lower end may be made to press upon
swinging arm 63 and thus release the type-carrying discs from engagement with
pawls 11.
Secured to the third arm of lever 49 is a rod 65. The latter is connected to and
rocks a spring-pressed rock-bar 66 having a pin 67 at each end, adapted to mesh
into the teeth of ratchet wheels 69, as clearly shown in Fig. 11. By means of the
bar 68, pivoted at its centre, one or the other of these pins is held out of engage-
ment with its ratchet wheel and the other is held in engagement with its ratchet
wheel. As pin 67 rocks through the reciprocal action of lever 49 and rod 65, it
feeds forward ratchet wheel 69; the latter through gear wheel 70, mounted on its
shaft, drives gear wheel 71 and winds inking ribbon 73, upon shaft 72 or unwinds
it. By changing the position of bar 68, the direction of the feed of this ink ribbon
can be changed. The ink ribbon 73 runs from shaft 72 over the printing line at
the top of the machine to enable an impression to be taken at that point.
Lever 75 is mounted in standard 74. In its backward and forward motion it
rocks an arm 76 mounted upon a rock shaft 77. Upon this shaft is also mounted
an arm and platen 78. When the platen is swung forward it presses paper strip 82"
and inking ribbon 85 against type 7 of type-carrying discs 5 and causes an impres-
sion to be taken of the said type upon the printing line. Thus upon the paper
strip 82 a permanent record is made corresponding to that printed upon the
removable slips at the printing line on the top of the machine.
Lever 75 has at its further end an arm 75 which through rod 79 rocks bar 80
back and forth. As it thus rocks, pawl 81 rotates ratchet wheel 82, tooth by tooth,
feeding forward the paper strip 82". A roller 83 mounted on the same shaft as
ratchet wheel 82 presses against roller 84 upon which inking ribbon 85 is wound
and thus feeds the inking ribbon forward from spool 86. The particular means
shown and described for feeding the ink ribbons, form no part of my invention
and are accordingly not given in full detail. Any suitable means may be employed
for that purpose without departing from the spirit of my invention.
Another device for automatically tripping pawls 11 and thus releasing the type-
carrying discs and operating levers, is shown in Fig. 8. This device is employed
when handle 42 is not used. 87 is a movable index finger upon the top plate of
the machine, mounted upon a rod 88. Rod 88 also carries a flange 89 at its lower
end. 92 is a bell crank lever pivoted at 92ª in the framework of the machine and
having a stop pin 94 at its lower end, and at its other end bearing against lever 59.
A toe 90, loosely pivoted to lever 92 at 91, is pressed by spring 95 so that its outer
end projects outward through an opening 90 in the front plate of the machine.
It also has a pin 93 projecting on one side with which flange 89 may engage.
When index finger 87 is turned into the position occupied by it in Fig. 2 marked
pay" in Fig. 2 (which is done when handle 42 is in use), the flange 89 through
pin 93 pushes toe 90 backward into the position shown in dotted lines in Fig. 8.
In this position toe 90 does not project beyond the face plate and is withdrawn
from operation. Whenever handle 42 is not in use, for example, when the machine
is used simply for adding and not for printing at the top printing line, finger 87
is turned into the position marked " com" in Fig. 2, in which position flange 89
is removed from contact with pin 93, whereupon toe 90 at once projects beyond
the face plate. In this position toe 90 will lie in the upward path of a portion
**

page_text: of movable carriage 21, as it rises after the unit or last operating lever has been
operated, and will be forced upward, carrying with it through stop 94, lever 92
and forcing back lever 59 and thus through arm 61 of that lever, and swinging
arm 63, tripping the pawls 11 and releasing type-carrying discs 5 and operating
levers 3, which at once return to their normal position ready for the adding of the
next number.
In order that swinging arm 63 shall be held by lever 59, 61 against pawls 11
long enough to ensure that dises 5 shall return to their original positions, a lock-
ing lever 97 is provided. It is pivoted on a shaft 99 turning loosely in plate 100
and is pressed upward by a spring as shown in Fig. 4 and has a locking pin 97*.
When lever 59, 61 is pressed back to release the type-carrying discs, pin 97" slips
behind lever 59 and holds 61 and 63 against pawls 11.
The pin is unlocked in the following manner. Lever 97 projects slightly from
the front of the machine alongside of the operating lever of the highest order and
an arm 98 projects over that lever so that, when the first key is operated in print-
ing or adding a number, lever 97 is depressed, locking pin 97" is withdrawn from
contact with lever 59, the latter is retracted by spring 62 and pawls 11 are free
to engage with teeth 10 of discs 5.
The adding mechanism of my improved device, in the form shown in the draw-
ings herein, consists of the following parts.
Pivoted to each of the operating levers 3 is a rod 101, the latter being pivoted
at its other end to an arm 102 which is loosely mounted upon the shaft of gear
wheel 104 and has a pawl 103 engaging with the teeth of gear wheel 104. Every
time the operating lever 3 is depressed gear wheel 104 is rotated one or more teeth
dependent upon the extent to which lever 3 is depressed. Gear wheel 104 meshes
with gear wheel 105 mounted upon the shaft of adding wheel 106 and having the
same number of teeth as the latter wheel. Thus adding wheel 106 rotates one
or more teeth for each operation of operating lever 3 or its actuating key, the
extent of this rotation depending upon the extent of depression of lever 3 or its
actuating key, and is prevented from rotating backward by spring a pressed pawl
Each adding wheel 106, carries two sets of numerals, 106 and 106b, each set
consisting of the digits 0 to 9 inclusive (the drawings show each wheel as carry-
ing twenty numerals or from 0 to 9 repeated once.) The set 106ª are placed upon
inclined faces of the teeth and are visible through opening 116 in the casing 115
and show at all times the total sum of the numbers added upon the machine. The
set 106b are type and are placed upon the end of the teeth for the purpose of
printing. Any means for printing may be employed. As shown in the draw-
ings it is done by means of a lever 114, platen 114ª and inking ribbon 113. When-
ever it is desired to secure a printed record of the sum, a piece of paper is inserted
opposite the platen, and the handle is pressed. The type 106b are so arranged that
the same number appears opposite platen 114" that appears on 106° at open-
ing 116.
The carrying mechanism consists of the following parts. A pin 106° for each
ten teeth, projects from the side of each adding wheel toward the adding wheel
of the next higher order. 109 is a rocking piece (one for each adding wheel)
loosely mounted upon shaft 110, held upright by spring 111, and bearing a pawl 107
pressed upward by spring 108 and also having a finger 109. The pawl 107
engages with the teeth of the adding wheel and gives as the wheel is rotated.
When any adding wheel has been rotated ten teeth, its pin 106° strikes finger 109*,
depresses piece 109 and pawl 107, thus positively feeding the adding wheel of
higher order forward one tooth. Rocking piece 109 is then retracted by
spring 111 to its original position.
By my improved device only one series of adding wheels is needed.
Adding may
be commenced upon any adding wheel and the adding will proceed from that
wheel to wheels of higher order without affecting in any way the wheels of lower
order. One adding wheel is employed for each operating lever and as many more
may be used as desired.

page_text: As many operating levers 3 may be used as may be found desirable without
necessitating any increase in the number of keys.
The type discs and wheels or other type-carrying mechanism may be operated
by the presser through any suitable connecting mechanism, my invention not
being restricted to the use of operating keys for this purpose. Many other changes
also may be made. in the apparatus shown and described herein, without depart-
ing from my invention.
In the form of machine shown in the drawings the type-carrying mechanism,
viz, discs 5 and adding wheels 106, represent different numerical orders, one disc
and wheel representing units, the next disc and wheel representing tens and so on.
As, in the form shown, the discs and adding wheels have no lateral movement
relative to the printing surfaces but are always in the same fixed position, so far
as lateral movement is concerned, relative to the printing surfaces, each disc and
adding wheel always and necessarily represent the same numerical order, one disc
and wheel always representing units, the next always representing tens, and so
on. This arrangement, however, is not essential to my broad invention, my
invention being embodied, as far as the elements under discussion are concerned,
as long as, in any number being set up for printing or adding, each disc represents
a different numerical order from that of each other disc used in setting up the
said number. For example, type-carrying mechanism might be so arranged that
upon the actuation of each key, the type-carrying mechanism would shift laterally
across the printing surfaces a predetermined distance, the presser for instance
being stationary and actuating each disc as it passes in front of the presser. In such
a structure each disc would move, to the left for instance, one numerical order at
each actuation of a key. For example, the first disc to be operated by the presser
would, in setting up the number 157, be moved three times to occupy the hundred's
place. In setting up the number 57 the same dise would be operated twice only
and would be moved into the ten's place. Any particular type-carrying disc might
represent different numerical orders in setting up different numbers but in setting
up any specified number such disc would always represent a different numerical
order from all the other discs.
My improved device has been described in connection with the United States
monetary system, but it is evident that it is equally applicable without any change
whatever in the mechanism comprising it, to any decimal monetary system.
My improved device can be adapted for use with the British monetary system
by slight changes in parts of the mechanism. This may be done in different
ways, but the way I prefer is as follows; to use twenty type keys instead of ten,
numbering them from 0 to 19 inclusive; to substitute in place of the unit's type-
carrying disc a type-carrying disc for pence with type running from 0 to 11
inclusive; to substitute in place of the tens'. type-carrying disc a type-carrying
disc for shillings containing the numbers from 0 to 19 inclusive; to place upon the
units' adding wheel numbers ranging from 0 to 11 and upon the next adding
wheel numbers ranging from 0 to 19; in these two adding wheels the pins 106
should be so arranged that the wheel for pence will move twelve places before
carrying to the shillings, and the shillings wheel should move 20 places before
carrying to the unit pound wheel.
