A communication from abroad by the UNION TYPEWRITER COMPANY, a Corpora-
tion organized under the Laws of the State of New Jersey, and having its
pincipal office at Jersey City, New Jersey, United States of America.
I, JOHN CORRY FELL, of the Fum of Fell & James, of 1, Queen Victoria Street,
in the City of London, Consulting Engineer and Chartered Patent Agent, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement
The present invention relates primarily to combined typewriting and adding
machines, and has for one object the provision of a comparatively simple, prac-
tical and effective combined typewriting and adding machine capable of writing
words and sentences as well as columns of figures and of automatically adding
the same, another object is to record the sum of the column without disturbing
or actuating the adding mechanım; another object is to correct an error in the
record, or to repeat a number or digit to print it moie legibly without operating
or actuating the adding-mechanism; another object is to return the number-
carriers of the adding mechanism to an initial position, as that in which the
naughts are in line and so to have the mechanism in readiness for reuse. another
object 18 to provide a combined typewriting, tabulating and adding machine
(having a power diven escapement-controlled carriage) in which the adding
mechanism is inactive until the carnage has reached a given point in its forward
taveise at which point the adding mechanism is brought into operative relation
with the carriage and with type operating mechanism, to release the carnage
from its controlling mechanism in its forward traveise and to arrest or atop the
cariage at any one of a number of different points uniformly spaced apart, and
to re-engage the same with its controlling mechaniam at or after the time the
adding mechanism is brought into operative relation with the type mechanism and
the carriage, another object is to operate a series of number wheels or other
number carriers one at a time or in succession from a single set of finger keys
which preferably control a set of type for 1ccording the numbers selected:
another object 18 to disconnect the adding mechanism from the typewriting
mechanism to allow of the use of the typewriter part of the machine as an inde-
pendent mechanism, and other objects as will hereinafter more fully appeal
To these ends, the invention includes features of construction and combinations
of devices hereinafter described and more particularly set forth in the appended
claims
The preferred form of the invention is illustrated in the accompanying diaw-
inga forming part of this specification, in which,

numeral or character
The framework comprises two parallel horizontal frames or plates 23 con-
rected by uprights 4, and two standards using at the rear of the uppe
frame 3 and connected by parallel houzontal iods 6 also the framework meludes
vanons brachets or studs, as will appear more fully heremafter The lower
frame 2 is provided with downwardly projecting feet 7 over which rubber sleeves
are placed, said sleeves projecting below the feet as shown The uprights
cast in one with the frame 3 and are connected with the frame 2 by means of
screws 8 which pass through the feet 7 and whose threaded ends engage with
threaded holes in the uprights 4, as shown in Figure 4 Sheet-metal or hard
rubber plates 9 are sprung into grooves 10 in the upper side of fiame 2 and the
under side of frame 3, thus enclosing the space between these two frames
are
The type bars 11 are formed in two parts 12 13 which are hinged together
at 14 in a direction at right angles to the axis 15 on which the type har 19
pivoted The axis 15 18 a straight shaft o bar pivoted or otherwise secured
in brackets 16 secured to the top of frame or plate 3 Each piece 12 18 pro-
vided with an enlarged circular end 17 which is formed with an open slot 18
whose hottom 18 formed to fit the round shaft 15 Each end 17 18 also provided
with a notch 19 which fits and receives the end 20 of the corresponding key
lever 21 The preferied method of pivoting the type bars is to fit each end 17
between lugs or brackets 16 forming part of or attached to the plate or frame 3,
as shown in Figure 1 The open slot 18 permits of the removal of any type-bai
without disturbing any other type bai The hey levers 21 are made of flat inetal
bais provided with notches 22 in then under edges which rest on knife-edges 23
seemed to and projecting upwardly from the top of plate 3 The keys 21 are
provided at the forward ends with suitable finger-pieces 24 The key-levers 21
are guided at each side of the pivots, as by the slotted guide-plates 25 26 secured
to the top of plate 3, as by screws 27, and are thus prevented from displacement
elatively to then pivot-pins 23 Each ker-lever 21 1s returned to its down or
tional position by a spring 28, one end of each spring being inserted in a hole
therefor in the top plate 3 and the other end thereof hooking over its lever 21
The space-key 29 is carried by levers 30 which are or may be pivoted and be held
down at their rear ends in the same manner as the key-leveis 21
The type has 11 are provided with three several type-faces a, b, c, of which
the middle type b constitutes the "lower case" and such other characters as

page_text: may be provided for. The upper type-characters c are the
and other characters as may be provided foi
+6
upper case
⚫ letters
The lower type a on the type
blocks are the numerals, the punctuation and other maiks The type are secured
to then respective bats in any suitable or known way, and hence this reques
no specific desciption here A guard or protective bar o fame 31 extends
around the ends of the type-bais and also down the sides of the low of type bais
At a point intermediate the pivots 14 and the type-blocks, the type-bai guard 31
18 becured to the bars 32 33 which form guides for the type bats when moving
to the printing point These guides 32 33 have rearwardly projecting aims which
are parallel to each other and which form a center guide 35 at the printing point
for the type bais Depending from the inner on rear ends of the guide-aims JJ
are arms 33 which are connected by oblique aims 30 with the name of the
machine, as two outer lugs 16 of the row of lugs at the type-bai pivots
The
head of the tie-1ods 36 is notched at 37 to form a further guide on centering
device for the type-bats The flat or square bais 12, forming part of the type-
bars, are provided with cams or inclines 39 adjacent on opposite the pivots 14.
The function of these cams 39 is to guide the adjoining type-bai during its
return to normal position so that it will fall into its proper position within the
enclosing guard oi bai 31. It will be observed that those cams or wedges 39
to the night, in Figure 1 of the contral font to back line incline outwardly
and downwardly while those to the left of that line incline outwardly
and downwardly, or in the opposite direction, (the white or non-shaded tiangulai
spaces in Figure 1 representing the cam-faces), hence, each mcline 59 to the
1ight of said line acts upon the type-bai to its night to move it outwardly while
it is returning to normal position, and each incline to the left of said line acts
upon the type-bai to its left to return it to normal position as it swings away
from the platen after being operated, A couple of combs 4041 extend across
from guide 32 to guide 33 and provide rests and separators for the parts 13 of
the type-bars 11
The type are inked as they move toward the platen by means of a roller 42
Journaled on a vertical axis in arms of a holder 43, which 18 in turn journaled
at 4 in arms or brackets 45 from the guide-arm 33 The holder 43 is provided
with a shield or guard 46 for preventing contact between the ink-1ollei and the
platen on the substance on the platen
The construction of the inking-1olle mechanism may be the same as that
shown and described in either of the British Letters Patent No. 9421 dated
July 20, 1886, and granted to Eugene Fitch and No 9792, dated July 12, 1887
also granted to Eugene Fitch, and is immaterial to my present improvements,
which are applicable as well to typewriting machines having bbons, pads, or
other inking devices
The paper-calliage comprises a rectangular frame 47 which is provided with two
pains of forwardly projecting aims 48 49, and with one member of the escape-
ment-mechanism. as the dogs or pawls The carnage 47 is also provided with
rearwardly extending studs or shafts 51 on which rollers 52 ate journaled, said
rolleis being shaped to fit the 1ods 6, shown as round 1ods in this instance By
1eference to Figures 3 and 4 it will be seen that one pair of rolleis 52 rides on the
upper rod 6 and that another pan runs underneath the lower od 6 and thus act
as guide-rollers only The paus of aims 48 49 are perforated vertically to receive
and guide the vertical 1ods 53 54 forming part of the platen-calle
The platen-
cale includes end-pieces 56 57 and tie-iods 58 The upright 1ods 53 54 are
attached to the rods 58 as by plates 60 and screws 61 62, the screws 61 passing
though the plates and engaging with threaded holes in the 10ds 58 and the
screws 62 passing through the plates and engaging threaded holes in the rods 53
54. The iods 53 54 are connected at their lower ends by a tie-bai 3 which 15
provided with an anti-friction roller 64 running on top of a 1od 65 of the platen-
shifting mechanism The platen 38 is fast to a shaft 66 which is journaled in
the end-pieces 56 57 of the platen-carlier. The ends of the shaft 06 are provided

page_text: with hand-wheels 67 68 by means of which the platen may be turned in either
direction The shaft 66 is provided, just outside the end-pieces 56 57 of the
platen-canner, with ratchet-wheels 69 70, and the end-pieces 56 57 are provided
with levers 71 72, pivoted thereto at 73 74. The lever 71 is provided with a
pawl 75, pivoted thereto at 70, and adapted to engage with and rotate the
atchet 69 and platen 38 Normally, the pawl 75 is pressed toward the ratchet by a
spring 77, secured to the end-piece 56 by a sciew 78 and bearing against the
real side of the pawl, and is normally held out of engagement with the latchet 69
by means of the pin 79 projecting outwardly from the end-piece 56 and engaging
with the beveled face 80 of the pawl-piece, since the sping 81 which holds
the lever 71 in its upper or normal position is of a strength sufficient to overcome
the resistance offered by the other parts to such action The sping 81 has one
end secured to the lever 71 by a sciew 82 and has its other end bearing on the
top of a screw 83 which projects from the end-piece 56 through a curved slot 84
in the lever 71 The reaction of sping 81 against the sciew or stop 83 tends
to lift the lever 71 The center of the are of slot 84 is the pivot 73, as will be
understood A sping detent 85, secured at one end to the end-piece 50, acts to
prevent accidental rotation of the ratchet 69 and platen 38, while it permits of
then rotation in either direction at will by means of force applied to either hand-
wheel 67 68. A similar detent may be used at the other end of the platen. The
cnd-piece 56 is provided with one or more holes 86 opposite the slot 84 for the
reception of a più or stop 86* for engagement with the upper ond of the slot 84
for the purpose of limiting the rotation of the platen to one o more spaces
coesponding to the distance between the teeth of ratchet wheel 69, according
to the number of holes 86 and that one of them in which the pin may be placed
The end of lever 71 18 formed into a ing for convenience of getting a hold upon
it to depress it for line-spacing The lever 72 18 or may be connected with its
atchet 70 in precisely the same way to rotate it and the platen for line spacing
If the slots 84 be of sufficient length to permit of at least two different widths
of line-spacing, the line-space level at one end may be set to give say one width
and the line-space lever-regulator at the other end of the platen may be set to
give a different width of line-spacing, whence it results that an operator may
wite matter of either or both of such widths of spacing without having to set
or reset a line-space regulator. this feature is of great convenience in writing
briefs and the like where many quotations are made and are put in half-space oi
solid while the remainder is put in with wider spacing between the lines
The paper is held against the platen by means of a roller 87. I prefer to
jounal the roller 87 in lugs or projections on the paper guide 88 which 18
pivoted to the ends 56 57 at 89 One or more springs 90 between said guides 88
and one of the 1ods 58 serves to press the roller yieldingly against the platen
A paper holder 18
provided for co-action with the platen above the line of punt-
ing or witing, said holder consisting of a small od 91 boine by pivoted aims 92
93 at the ends of the platen or platen care. The aims 92 93 are provided with
extensions or handles 94 95 whereby the frame formed by said aims, Journaled
shaft 50 and od 91 may be locked to move the rod away from the surface of
the platen, as in inserting paper. A spring 96, coiled about the rod 59, has one
end connected with the rod 59 and the other secured to some fixed part of the
platen canner, as end 56, and tends to keep the said shaft on 1od 59, àims 92 93
and rod 91 in the positions shown in Figures 1, 2 and 3.
The end-pieces 56 57, of the platen carrier may be provided with open-ended
oblique slots 97 for the reception of the pivot iod or shaft 66, thus allowing
of the ready removal of the platen from the canier It will be noted that
detent 85 tends to prevent removal of the platen being between the bearing in
slot 97 and the open end of the slot
The carriage is provided with a toothed bar 98 fast to the top of frame 47,
which bar is provided with longitudinal grooves 99 at its front and rear sides.
Upon this bar 98 are mounted two margin-regulators or cannage stops 100 101,

page_text: the stop 100 being shown in perspective in Figure 18
These stops are each
formed of two parallel aims 102 united at one end by a cross-tie 103 which 18
adapted to entei o fit in between the teeth of the bai 98, as indicated in dotted
Imes in Figure 4. The aims 102 are provided with inwardly projecting pins 104
for engagement with the grooves 99, thus providing pivots about which the
stops 100 101 are swung to engage and disengage them from the teeth of the
bai 98 when adjusting them along the same The stops 100 101 respectively co-
act with fixed abutments 105 100 respectively affixed to the tops of the end-
standards 5, shown Figure 4. The stop 101 also caries the bell-tip 107
which is pivoted at 108 to an aim 109 igidly attached to the stop 101 A
pin 110 on the aim 109 acts as a stop to limit the motion of the tip 107 in one
direction, The bell 111 is canied by an aim or bracket 112 on one of the up-
rights 5, and the bell-hammer 113 s pivoted at 114 to an aim on branch of
biachet 112, and is provided with an aim 115 for co-action with the tip 107,
as will be understood.
The letter-feed mechanism will now be descubed
The cannage has fixed
thereto a plate 116 which is provided with a tooth 117 adapted to engage with the
teeth of a rack 118. Lying on top of plate 116 is a second plate 119 which 18
provided with a tooth 120 also adapted to engage with the teeth of the rack 118.
The plate 119 has a limited movement relatively to the plate 116, as by means
of the screws 121 and slots 122 123 The screws 121 pass loosely through the
slots 122 123 and engage with threaded holes in plate 116 (and lower bar of the
canage 47) Preferably, the slot 123 is larger in every duection than the body
of the screw which passes through it, this permitting of the retraction of the
carriage, toward the night without having to disengage the rack from the escape-
ment pawls o re versa A spring 124, fast at one end to the plate 116 and at
the other end to a pin on the plate 119, acts to draw the tooth 120 toward the
lack 118, and also to slide the plate 119 toward the left-hand side of the machine
whenever the tooth 120 16 released from engagement with the rack 118. The
rach-ba 118 18 borne by aims 125 which also carry the universal-bar 126 and is
normally lifted by a spring 126 The levels on aims 125 are pivoted at 127 in
brackets 128 fast to the top of plate 3. The carnage is diawn to the left by
means of the cord or stiap 129 which 16 secured thereto at one end, as 130, and
to the grooved periphery of a wheel 131 which is journaled to the bracket 112,
and by means of the coiled or spial spring 132 which has one end connected to
the fixed framework, as a standard 5, and the other end connected to a lever of
cam on the wheel 131 By preference, the spring 132 18 adjustably connected
to the standard 5, as by the threaded od 13 passing loosely through the
standard and the adjusting nuts 134 on said 1od 1.3 at each side of the standard 5.
Also the other end of spring 132 19 preferably connected with the lever or cam 135
on wheel 131 by means of a cord or strap 136 A stiut on brace 137 18 shown
between the 1ods 6, the function of which is to prevent bending or distortion
of the same, this strut is perforated at 138 to allow the spring 132 to pass
freely through it.
The platen-shifting mechanism will next be described The platen cartier 55
is supported independently of the carriage by means of the rods 53 54 and bai 63
and iolle 64, as above described, and the 1od 65 on which the roller 64 traveises
during the operation of the machine The rod 65 18 borne by arms 139 140 fast
on a shaft 141 which is journaled in brackets 142 using from the top of frame 3.
An extension 143 of the arm 140 is connected with the V-shaped lever 144 by a
pitman or link 145 (Figure 15) which is pivoted to the end of the arm 143 and
at or near the point of the ✓ of lever 144 The lever 144 18 pivoted at 146 to a
bracket 147 rising from the top-fiame or plate 3 One bianch of the lever 144
13 provided with the "Cap" key 148 and the other branch is provided with the
Fig" key 149. The arms 139 140 are normally held in a central position by
the weight of the platen-carrier, platen and appurtenances, and the springs 150
and stops 151 for the springs. The strength of the springs 150 is such that they

page_text: lift the platen-canner and the parts supported thereby until the springs 150 are
stopped by the stops 151, this bungs the platen in such relation to the type
on the type-bars that the middle types thereof co-act with the platen When
the key 149 is depressed, the rod 65 18 moved downward and carries with it
the springs 150, as in Figure 15, this allows the platen-cale and parts carried
thereby to fall or move downward, and thus brings the platen in such position
that the lower types a on the type-bais co-act with the platen to punt the figures
und other characters shown at the front of the keys 24 When the key 148
.
16
For the
is depressed, the parts take the positions shown in Figure 15 in dotted lines
(except that springs 150 rest agamst stops 151) and the platen-calier and parts
supported thereby are raised into position to co-act with the upper types con
the type bais, thus printing capital letters and such other characters as may be
employed an addition thereto on such upper ends of the type-blocks. The
bracket 147 is provided with two lugs or ears 152 153, and these are provided with
adjustable stops 154 155 to the lever 144, these stops may be conveniently made
by screws which engage threaded perforations in the lugs and lie in the path of
the lever, as of that arm thereof which canes the key 149. The upper part of
the bracket 147 may be bent over to form a flange 156 and this flange may be
provided with a guide-slot 157 for the lever 144 It is sometimes desuable that
the Cap
or Fig key be held down while the writing progresses
purpose of automatically holding the lever 144 in either of its extreme limits of
motion there are provided two catches 158 159, which are carried, respectively
by spring alms 160 161 The catches are in the form of notch pins secured to
the spring arms and adapted to pass through a perforation in that bianch of
lever caying the key 149 and to engage with the side of the flat level.
Preferably, the aims 160 161 are secured to the bracket 147 on the side thereof
opposite that on which the lever 144 is placed, and the tension of the spring
aims 160 161 is such that they stand away from the bracket with theu pins 108
159 opposite on entering perforations 102 in the bracket. The perforations in the
bracket 147 are so placed that the perforation 163 in the lever 144 will register
or be in line with one or the other of the perforations 162 whenever that lever 18
in its extreme positions or against the stops 154 155. Whenever it is desired to
hold the platen in either of its extreme upper or lower positions, the corespond-
ing one of keys 148 149 16 depressed until stopped by one on the other of the
stops 154 155, whereupon the coresponding catch (158 or 159) 18 pushed in until
its side notch has passed through the perforation 103 so far that it will catch
against the side of the level 144 when that love is released, whereupon the
lever is let go and is caught. In order to release the lever 144 when it has been
locked as above de-cubed, it is only necessary to push down the depressed key
(148 01 149), whereupon the spring aim carrying the corresponding catch will
be ficed tom the lever 144 and will sping out and carry its catch out of the
path of the level 144, which can then be returned when released to normal
position through the power of springs 150 or the weight of the platen-carier
and parts supported thereby
The operation of the foregoing devices has been given in substance during the
description of the parts, and need not be repeated
For the purpose of adapting the typewriter to the use of book-keeperis on others
who have to make out statements of bills, there is provided adding mechanism
which can be thrown out of and into operation at will
At the left-fiont of the machine and between the frames 23 are a series of
adding wheels in two sets 164 165, there being seven of the former and two of
the latter shown, or nine all told, but I do not Immit myself to nine, since I may
use a greater or lesser number The adding wheels are loosely mounted upon a
shaft 166, journaled in brackets 167 mounted on the frame 2 to have a motion
relatively thereto in the direction of the length of the shaft 166 such motion
18 conveniently obtained by means of guides 108 which overhang a plate 169
to which the brackets 167 are fast. The plate 169 is provided with an arm 170

page_text: terminating in a hand-piece or knob 171 by means of which the plate 169 and
parts supported thereby may be shifted back and forth for a purpose presently to
appear. The to and fro motion of the plate or adding wheel carriage 169 18
limited by the fixed stops 172 173 in the path of the plate The brackets are
also provided with two shafts 174 175 parallel to shaft 166, and are tied together
by the tie-rods 176 177. The brackets 167, plate 169, and tie-1ods 176 177 form
a rigid frame or carriage. The shaft 174 has a series of toothed wheels or
gears 178 journaled thereon, there being one such gear 178 for each wheel of the
adding-wheels, and each gear 178 being independent of all the other gears 178
The adding-wheels 164 165 are each provided with a gear 179 fast thereto, and
the gears 178 179 are in the same planes The adding-wheels except the right-
hand wheel 165 are also provided with gears 180 fast thereto on their other sides,
whence it comes that the gear 179 of one adding-wheel is next or adjacent to it
the gear 180 of the adding-wheel next o adjacent to it. The shaft 175 has a
series of pinions 181 independently journaled thereon, said piniona 181 acting to
transmit motion from the gears 178 to the gears 179 and so to the number
wheels 164 165 The pinions 181 have alongside them independent pinions 182
likewise journaled on the shaft 175 and meshing with the gears 180 on the number
wheels.

وو
Each gear 178, excepting the extreme left-hand one, is provided with two
pinions 183 independently pivoted thereto on pins 184 at opposite sides of its
center of motion, and in the plane of the adjacent pinion 182, the said pinions 183
being adapted to mesh with the said pinion 182 during the rotation of the
gears 178 The pinions 183 are adapted to vield or turn fieelv in one duection
only, this is obtained by means of springs 185 secured to the gears 178 at one
end and of a length sufficient to act as detents in conjunction with the teeth
of the pinions 183. The manner in which said springs act as detents is indicated
in Figure 9, and the manner in which the pinions 183 are permitted to have
motion in one direction is indicated in Figure 10 where the spring 185 bears upon
a tooth of a pinion 183 which rotates toward the left-hand, thus flexing the
spring aside until the tooth passes the end of the spring, when the latter snaps
in behind the tooth, ready to act as a detent The relative positions of the number
wheels, the gears fast thereto, the gears 178, pinions 181, 182, 183,
and springs 185 are such that the cariving is from the number
wheel of lower denomination to the wheel of higher denomination;
that is to say the rotation of the "unit" wheel, for example, to or
past the zero is transmitted by means of the gear 179; pinions 181, gear 178,
pinions 183, 182 and 180 to the "tens wheel But the movement of the tens
wheel to or bevond the zero 19 not transmitted to the unit wheel since the
pinion 183, which at that time may be in mesh with the corresponding pinion 182,
tuns idly on its pivot, that 18, does not rotate the gear 178 which carries it
I have shown two pinions 183 for the reason that I have provided the number
wheels each with a duplicate set of numbers, each occupying a semi-circumference
of the wheel, it is obvious that I could place but one set of digits upon each
number wheel, in which case I would dispense with one of the pinions 18%
on each gear 178 and also that I might place more than two sets of digits upon
the circumference of the number wheels; in which case I would employ a corres-
ponding number of pinions 183. It is obvious that I may opeiate number-
bearers of other forms in lieu of the number-wheels 164 165 without change in
the mechanism shown For the purpose of preventing accidental displacement
of the number-wheels, a series of detents 186 187, formed integially with or
attached to a bar 188 which is secured to the top of the brackets 167 is provided:
the said detents 186 187 respectively engage the gears 179 and 180 as shown in
Figure 8. or they may engage one or the other of these sets of gears The plate 9
in front of the number wheels is provided with an elongated slot 189 through
which the numbers giving the summation of the addition are visible
By preference, the adding device is not mtended to be used or brought into

page_text: operation until near the end of a line of writing across a page and not even then
unless it is so desued and a suitable adjustment of parts made There is there-
fore provided a mechanism under the control of the carriage which comes into
operation at a predetermined point during the traverse of the camage to the left,
which mechanism is adapted to engage the gears 178 in succession or one by one
beginning at the left-hand side in Figure 5, and to rotate the same should any
one of the keys carrying the numerals 1 to 9 be struck and provided that the
geais 178 are in position during the step-by-step movement of sand driving
mechanisin to be turned thereby. The sand driving mechanism is provided with
a gear 190 for engagement with the said gears 178 when the latter are in the
position shown at Figure 5, but should the slide or carriage 169 be moved
against the stop pin 172, the gear 190 would, in its step-by-step movements from
left to right come opposite the intervals between the said geais 178 and so fail
to turn the same even if any of the said keys should be operated, thus rendering
the adding mechanism inoperative for the time being
The mechanism whereby the aid gear 190 18 rotated to a greater or lesser
extent will now be described A 1ack 191 18 attached to the carriage beneath
the frame or plate 3, as by means of downwardly extending arms 192, which pass
through a slot 193 in the said plate or frame 3, and the bar 194 canied by said
arms 192
The rack 191 16 adapted to engage with a pinion 195 fast upon a
shaft 196 extending longitudinally of the machine and journaled in brackets 197
attached to the bottom plate or frame 2 The shaft 196 18 provided at its front
eud with a pinion 198 which meshes with a rack 190 movable transversely of
the machine in guides 200 The bar carving the ack 199 has a forked bracket 201
fast thereon and the ends of the bracket 201 are perforated to receive a round
shaft 202 which is journaled in brackets 203 affixed to the bottom frame 2 of the
machine The pinion 190 lies between the forks of the bracket 201 and 18 splined
or otherwise secured to the shaft 202 so as to turn therewith and to slide length-
we thecof. The shaft 202 is provided with three adjustable collais 204, two of
which event its own motion endwise, and the thud or middle one of which
limits the motion of the bracket 201 towards the right.
From the descubed construction it will be seen that whenever the rack 191
meshes with pinion 195 during the motion of the jack and carnage to and fro,
the rack 199 and duver pinion or gear 190 are moving in directions the reverse
of the duections of motion of the paper carnage, inasmuch as the rack 191 engages
the top of the pinion 195 and the hack 199 engages underneath the pinion 198
That 18 to say, the driver 190 moves from left to night as the paper
canage moves from night to left and Lice Versa The purpose of
this arrangement of paits, which 18 the preferred arrangement merely,
is to add from left to right and to have the numbers shown in the slot 189 arranged
in their natural order that is to say, to have the higher denominations at the
left-hand so that the numbers will be read from left to right; obviously the
punting takes place from left to night during which time the paper carriage
moves from light to left
It will be observed also that the pinion 198 is larger in diameter than the
pinion 195 it results from this that the rack 199 and the pinion 190 carried
thereby move at a higher rate of speed than does the paper-carriage, or, to
state it differently, the motion of the paper-carriage as communicated to the
driver 190 is multiplied or increased. I prefer to multiply the motion or increase
the speed between the paper carriage and that element of the adding mechanism
which has a motion of translation (the axial motion of the gear 190 in the
instance shown in the diawings and herein described) for the reason that I prefer
to arrange the numbers of digits upon the peripheries of independently notatable
wheels or number carers and to arrange these wheels side by side in line and
to provide each wheel with suitable independent means, as a gear, whereby it
may be rotated (except in the operation of carving) independently of all the
other wheels, in order that the numbers may be read off at a glance it is neces-

page_text: sary to make the number wheels of a width or thickness (exclusive of their
attached gears) greater than the uniform letter space feed commonly employed
in typewriting machines; the distances from center to center of the adding wheels
(or of their independent operating gears) is therefore greater than the uniform
letter space feed of the paper cariage and the driver is moved axially step-by-
step a distance equal to the uniform distance from center to center of the
gears 179
It is pointed out that in this instance the number wheels 165 are
separated from the number wheels 164 by a space to provide for the decimal
point and that this fact does not form an exception to or invalidate the statements
just made inasmuch as the driver moves from the units wheel to the tenth wheel
in two equal steps instead of one and without being rotated while 80 moving
It will be obsci ved that, as between the driver 190 and the adding mechanism
operated thereby, one of these elements 19 stationary upon the framework of the
machine, while the other element 18 movable on said frame relatively to the first
named element, in the instance shown, the diver is the element which has such
relative motion or motion of translation
For the purpose of securing that the pinion 195 and the parts operated thereby
shall always be in a given initial position for engagement with the rack 191,
the bar 194 is provided with a long locking bar 205 whose lower surface or edge
is in line with the center of shaft 196 (extended) and the shaft 196 is provided
with a collar 206 fastened thereto and having a semi-cylindrical block or lug 207
lving beneath the rod or bar 205 with its flat face adapted to lie closely against
or near the lower edge of the bar 205 That is to say, the lug 207 18 eccentrically
mounted upon the shaft 196 and the lug and shaft are held against motion as
long as bar 205 18 over and against the lug The bar 205 ends at a point adjacent
to the rack 191 so as to allow said rack to rotate the pinion 195
The means whereby the shaft 202 and pinion 190 are rotated will now be
described. Each of the key-levers 21 whose keys carry the digits 1 to 9 is pro-
vided with a link 208 pivoted thereto at one end; the other ends of the links are
nivotally connected with levers 209 pivoted on a shaft 210 which is secured
in brackets 211 rising from the fame 2 Each lever 209 is provided at its front
end with a cam or inclined plate 212 secured thereto Each of the cams 212 is
designed to co-act with a corresponding one of a series of steps 213 on a sliding
frame 214. The frame 214 is provided with side grooves 215 which engage with
the aims 216 of a frame 217 which 38 journaled upon a shaft 210 and extends
forward over the shaft 202 towards the front of the machine The frame 214
1s provided on its underside with two ratchet-bars 218 which mesh with the top
side of ratchet wheels 219 which are secured to the shaft 202 A pair of springs 220
engaging pins 221 on frame 214 and pins 222 on the frame 217 diaw the said
frame 214 towards the rear of the machine and against the stop 223 on the
frame 217 The steps 213 are preferably arranged obliquely to the line of motion
of the frame 214 and have a series of stops 224 placed opposite them for engage-
ment with the vertical lear edges of the cam plates 212, while the cams 212 are
preferably arranged with their working faces in line
The operation of the foregoing adding devices is as follows At a predeter-
mined point in the traverse of the carriage, the bai 205 passes beyond the lug 207
and so releases the shaft 196, and the pinion 191 is moved to a position in which
its first tooth has meshed with the pinion 195 and has turned the shaft 196 and
moved the rack 199 and pinion 190 from the position shown in Figure 5 to bring
the pinion 190 into mesh with the first gear 178 from the left in Figure 5 On
the downward stroke of any key the corresponding type block is thrown against
the platen and a character impiinted upon the paper thereon, the universal bar is
lifted and the rack bar is rocked from the movable to the fixed dog on the car-
riage On the release of the key the type bar and kev lever are returned to normal
positions and so also the rack bar 118; the carriage now moves forward one letter
space and the rack 191 rotates the pinion 195, shaft 196 and pinion 198 corres-
pondingly and the rack 199, bracket 201 and pinion 190 are moved from the first

page_text: to the second of the pinions 178, counting from the left-hand side of Figure 5.
Upon the depression of any key on the keyboard and its subsequent release the
pinion 190 will through the described mechanism move from the second to the
thud of the gears 178 in Figure 5, counting from the left-hand side, and so on
upon the depression of the keys on the keyboard thereafter But in none of
these operations of keys will the pinion 190 be rotated by the shaft 202, thus
rotating the corresponding gear 178 and number wheel, unless the key operated
carries one of the digits 1 to 9 inclusive It will thus be seen that the
pinion 190
may be moved from the position shown in Figure 5 to the limit of its right-hand
movement and hack again without rotating any of the gears 178 and number
wheels If, however, during the traveise of the pinion 190 from left to right
and while it is in engagement with any one of the gears 178, one should depress
any of the keys carrying the digits, the corresponding lever 209 is operated
and the cam 212 of that lever 209 engages with the step 213 opposite it and
pushes the frame 214 forward until the step reaches the straight portion or
dwell at the forward end of the cam, after which the further motion of the
lever 209 does not cause motion of the plate 214 towards the font Duing this
forward motion of the plate 214, the wheels 219 are rotated as described and with
them the shaft 202 and pinion 190 The amount of the forward motion of .the
plate 214 and the rotation of shaft 202 and pinion 190 depends upon the particula
kev depressed, inasmuch as the cams 212 each give a throw to the plate 214
different from the throw given to said plate by each and all of the other of said
cams 212
This difference of throw is secured by arranging the cams 212 18 a
straight me at right angles to the direction of motion of plate 214 and by
ananging the faces or steps 213 obliquely to the line of motion of the plate in
such war that the cam 212 coresponding to the key carrying the numeral 1
moves the plate 214 a given distance (unit), and the cam 212 corresponding to the
numeral 2 moves the said plate 214 twice as far as the "1" key; in like manner
the ""key causes the plate 214 to be moved a distance of three units or three
times as far as by the "1" hey and so on for the remainder of the kevs carving
numeral These variable throws of the plate 214 are transmitted through the
described gearing to that particular gear 178 with which the pinion 190 may he
in mesh, and from said gear 178 the notion is transmitted through a pinion 181
to a pinion 179 and so to the corresponding number wheel Assuming that the
wheels are all at zero and that we wish to write 1499915 96 the pinion 190 is
brought into mesh with the extreme left-hand pinion 178 since the first digit
18 to be shown upon the extreme left-hand number wheel and the keys carrying
the digits are now operated On the depression of the "1" key, its corresponding
cam 212 moves the plate 214 forward one space or unit and rotates the shaft 202,
pinion 190, left-hand pinions 178. 181 and 179 and brings the digit "1" in view
at the extreme left of slot 189 in Figure 7 On the release of the "1" key, the
paper carriage moves forward one letter space, the 1ack 191 rotates the pinion 195
and the motion thereof is transmitted to the pinion 190 in the manner before
descubed, causing it to move from the first gear 178 at the left in Figure 5 to
the second gear 178 and to mesh therewith and the springs 220 return the
plate 214 to normal position and the ratchet teeth 218 ide o slip over the
atchet teeth 219, the plate 217 lifting at such time Possible reverse rotation
of the shaft 202 at such times may be prevented by suitable means, as by a
roller detent 225 engaging one or both the intchet wheels 219, the said detent
being cared by a spring 226 secured to the bottom plate 2; also, any possible
overthrow by the plate 214 is prevented by the locking of the plate by means
of the parallel front and rear edges of the cam piece 212 locking between the
forward step 213 and the rear step 224 opposite it The "4" key is next depressed
and its cam 212 causes the plate 214 to move forward four times as far as before,
thus imparting four times as great a motion to the parts operated by the plate 214
as in the previous case, and brings the numeral 4 up alongside the numeral 1 at
the slot 189 In similar manner the remainder of the digits before the decimal

point are witten, it being observed that theic shall be no punctuation marks
witten at all When the number in the units place has been written the
pinion 190 does not, m the instance shown, move on the gear 178 corresponding
thereto into mesh with another gear 178, but moves into a space between the
gear 178 coresponding to the units and the gear 178 corresponding to the
enths on the fist digit to the night of the decimal point For this reason the
number wheels coresponding to tenths and to units and then corresponding
operating pinions are twice as far apart as are the number wheels and the opera-
ting pinions at the left of such decimal point, as shown in Figure 5 Lather the
spare key on the key canying the period (decimal point) may be struck at this
place, whereupon the pinion 190 will be moved forward into mesh with gear 178
Corresponding to the tenths position and the remaining digits (96) may be
imprinted and shown in the slot 189 The paper calliage is now returned to
the night and the pinion 190 through the described connections is moved to the
left of the machine As the rach 191 moves out of mesh with the pinion 195
the locking bat 205 comes over the flat portion of the stop 207 and so prevents
any further motion of pinion 195 and the parts operated thereby and pinion 190
comes to rest, as in Figure 5 It will be observed from the foregoing operation
that four of the number wheels in the actual machine would have then 9's show-
ing opposite the slot 189, to wit, the 9 in the tens of thousands, the thousands,
the hundreds and the tenths With these number wheels in these positions one
of the pinions 183 184 on each of the corresponding gears 178 is in mesh with
the corresponding pinion 182 ready to "cany" to the next higher denomination
upon the run the tuning forward (adding) of either of these four number wheels
Let us assume that the number next to be witten is 1000 The paper calliage
is moved forward on towards the lett until it is in position for writing the
numeral 1 in its proper position, in so moving the cannage forward the shaft 190
is unlocked and is iotated by the rack 191, thus moving forward the pinion 190
until i engagement with the gear 178 corresponding to the thousands number
wheel Upon operating the 1" key the following operations occur. -the
plate 214 is moved forward one unit oi space and this motion is transmitted to
the thousands wheel, turning it so that it shows the zero in the slot 189 at the
same time the pinion 183 or 184 on the thousands gear 178 1otates the pinion 182
in mesh therewith and this pinion 182 1otates the tens of thousands number wheel
to bing the naught into view in the slot 189, and the pinion 179 on the tens
of thousands number wheel 164 1otates its diving pinion 181 and said diving
pinion 181 rotates the tens of thousands pinion 178 forwardly one space, and the
caying pinion 183 or 184 on said tens of thousands pinion 178 1otates the
calving pinion 182 with which it is in mesh, and the last named pinion 182
1otates the hundreds of thousands wheel 164 to bring the numeral 5 into position
opposite the slot 189 But the forward tuining or adding motion of the thousands
number wheel 164 does not cause the hundreds wheel to turn forward from the
position in which it shows the digit 9 at the slot 189 to the position in which it
would show the naught at said slot, although the pinion 180 on the thousands
number wheel 164 1otates its corresponding pinion 182 in the duection in which
the latter is moved when can ying, yet nevertheless there is no motion of the
hundreds wheel 164 because the pinion 183 01 184 which 18 in mesh at this time
with the last named pimon 182 iotates freely in the duection in which it must
alip past its spring 185 (the sping 187 engaging with the hundreds wheel 164
being stronger than the spring 185, the latter vields) At the completion of
this operation, the number wheels show 1500915 96 at the slot 189
For the purpose of returning the number wheels to an initial position or
zero or that in which the naughts of all the wheels are opposite the slot 189, 1
provide a roller 227, the shatt of which is journaled in arms 228 pivoted upon the
shaft 177 aforesaid One of the arms 228 is provided with an extension 229
downward and forward to the front edge of the machine and the frame or plate
is cut away at 230 to permit the finger to reach the finger-piece on the aim 229.

page_text: The shaft 231 of the roller 227 18 extended beyond the supports 228 to the right-
hand side of the machine where it is provided with a knurled knob 232 whereby
at may be turned In order to stop the number-wheels in their initial position
when they are returned thereto, the the 1od 176 has pivoted thereto a plate 233
and thus plate is provided with a series of extensions, fingers or stops 234, there
being one such stop for each of the pinions 178. The pinions 178 are each
provided with two pins 235 and 236 at opposite sides of the center thereof and in
position to co-act with the ends of the stops_234 The plate 233 hangs loosely
from the shaft 176 in such wise that the ends of the stops 234 are normally in
position to co-act with the stop pins 235 236 as the wheels 178 are notated in the
duection of the auow at Figure 10 The 1olle 227 normally beans upon the
number wheels with so light a pressure that it does not interfere with the proper
1otation thereof in the operation of the machine When it is desired to return
the number wheels to their initial position a finger is placed upon the finger-
piece of arm 229 and the aim is pushed rear waidly, thus pushing the roller 227
against the perphenes of the number wheels, and at the same time the knob
vi handle 232 18 10tated to cause the roller 227 to rotate in the duection of the
allow at Figure 10, the number wheels are thus 1otated by fiction against the
resistance of the retaining springs 186 and 187 and the number-wheels of course
1otate then diving geais or pinions 181 182 and 178 The wheels 178 are
otated in the duection of the arrow thereon at Figure 10 and the carrying
wheels 183 thereon pass the pinions 182, the springs 185 being flexed aside by
the teeth of pinions 183 as indicated in Figure 10, where the pinion 183 in mesh
with pinion 182, 18 10tated toward the left thereby, and when the teeth which
flex the springs 185 each pass the corresponding sping-end, the sping snaps in
behind the tooth ready to act as a detent The rotation of the shaft 231 18 con-
tinued until all the wheels show the naught at the slot 189, each wheel being
stopped when a naught thereon comes opposite said slot by the contact of pin 235
or pin 236 on its driving pinion 178 with the end of the corresponding stop 234.
The lever 229 and the knob 232 are now released and the machine is ready for
те-цье. Care must be observed, however, in returning the number-wheels to zelo
to have the gear 190 out of mesh with all of the geais 178, this may be secuied
by returning the paper carriage so far to the right as will move the said pinion 190
to the position shown at Figure 5
It sometimes occurs in typewriting that the impression made is indistinct and
it is necessary to again strike the key whose corresponding type made the indis-
tinct impression in order to obtain an impression of sufficient distinctness; on it
may happen that the wrong key has been struck and it is necessary to erase the
imprint erroneously made and to strike the proper key; in the first case the
typewter cannage is moved backward one step, or until the scales and pointers
show that the faintly impressed letter or character is at the printing point and
then the proper key is struck, in the second case the erroneous impression is
first erased and then the cannage 18 80 moved as to bring that portion of the
paper to the printing point and the proper key is then struck. In the use of the
combined typewriter and adding mechanism, other steps in addition to the
easure and proper positioning of the cannage (or the latter alone) are requied
before the proper key is to be struck, if the machine is in position to be adding
and a digit-bearing key has been struck elioneously In the last named case
the stuking of a digit bearing key elloneously will operate the corresponding
number wheel and turn it a distance corresponding to the digit struck
erroneously and will imprint the digit upon the paper in the typewriting machine.
If a digit is but faintly impressed upon the paper and it 18 desued to deepen the
impression or if the wrong key has been struck, the corrections requned aie those
already pointed out, and also a correction in the adding mechanism It ordi-
nally happens that the typewriter operator is aware of having struck the wrong
kev as soon as the erroneous stroke is made and the errors are commonly noted
for subsequent correction but in the case of the adding machine and typewriter

it is preferable to make the conection at once and this may be done as follows
For example, the numbers shown in the slot 189 may be "999" and the pinion 190
may be in engagement with the pinion 178 which operates the units wheel 164,
and one may strike the "7" key when intending to stake the "G" key, this
would cause the number shown in the slot 189 to be "1006" whereas the number
should be 1005" and the impression upon the paper would be a 7 undei-
neath the "9' in the unit's place In order to make the necessary correction
the "7" upon the paper is erased, also the operator by means of the finger
piece 171 and arm 170 moves the adding mechanism caiiiage from the position
shown in Figure 5 over against stop 172, thus bringing the gears 178 in positions
in which they are out of mesh with the diver 190 in all the step-by-step posi-
tions thereof The operator now tuins the thousands, hundreds, tens, and units'
wheels backward by hand or by a pointed instrument inserted between the teeth
of the gears of these wheels to bring the naught of the thousands wheel and the
"9's" of the other, of said wheels opposite the slot 189, also the paper-caruiage
15 moved backward step-by-step until the "9" of the number 999" in the
unit's place is in such position that the impression made by stinking any key
will be immediately beneath it, the operator now moves the adding mechanism
cari lage by means of the handle 171 to bring it over against stop 173 on in the
position shown in Figure 5; this will bring the diver 190 into mesh with the
gear 178 which operates the unit's wheel of the adding mechanism. The operator
now shikes the proper key, the "8" key, thus imprinting the "6" underneath
the "9" the unit's place and rotating the unit's wheel from the position in
which it shows the "9" in the slot 189 to the position in which it shows. the "5"
in said slot, incidentally, the "carrying mechanism" rotates the tens, the hund-
eds and the thousands wheels to cause the first two to show their naughts in said
slot, and the last to show the figure "1" in said slot, or the adding mechanism
will then show "1005" in the slot 189
"
For the purpose of retaining the adding mechanism canlage 169 against the
stop 172 or stop 173 as the case may be, the pin 171 co-acts with a sping 171,
having a V-shaped end, the action of the spring tending to force the handle and
carriage in one direction or the other according to which side the point of the V
the finger piece 171 may be When the caiiage 169 is against stop 172 the
gears 178 are thrown out of proper relationship to pinion 190 so that as the
pinion 190 moves step-by-step to the night it always takes position intermediate
to the gears 178 and so falls to turn any of them should it be operated by the
striking of the digit bearing ker in the key-board of the machine
When it is desired to strike a digit bearing key a second time in order to make a
previously made imprint of a digit more clear or visible, the procedure--assum-
ing that one 18 using the adding mechanism and has just struck a digit key and
obtained a faint impression-is or may be as follows The adding mechanism
is moved by means of handle 171 until ariested by stop 172 (in which position
gear 190 does not rotate any of gears 178) and then the typewter carriage is
moved to bring the faint impression to the printing point, and the proper kev
18 stuck with sufficient force to clearly imprint the digit; afterwards the adding
When
mechanism is moved over against stop 173 and the work may proceed
the faint impress is that of the naught, the carnage of the typewriter is moved
to bring the faint naught to the printing point and the naught key is again
struck. Inasmuch as the naught key is not connected with the duver 190 to
And
rotate the latter, the adding mechanism requies no attention in this case
it is noted that the same thing is true when the naught key has been erroneously
struck and an erasure is required on the paper on the platen.
In recording the sum of a column of numbers, which sum is shown in slot 189,
the adding mechanism is first moved over against stop 172, in which position
driver 190 does not actuate the gears 178; the carriage is then positioned to write
the sum in proper relation to the decimal point, the sum is read from the number

page_text: showing in slot 189 and the proper keys are operated to record the same on the
paper on the cane.
in making out tabulai statements on bills upon a typewriter, mistakes are
liable to be made in commencing the waiting of the number unless considerable
care be exercised to avoid them For example, one item may begin with tens of
thousands and the next item with units In order to provide to quickly and
accurately positioning the paper cantage for beginning the writing of any numbei
01 amount within the limits of the adding mechanism, I provide a series of eight
heys (more or less) at the night-hand side of the key-board, such heys being
numbered 237, 238, 239, 240, 241, 242, 243, and 244 and respectively marked with
the decimal point, unit, tens, and so on to the millions
The levers 245 cartying
the said keys are pivoted at 240 to the top plate 3 and extend rearwardly to near
the paper carnage 47 where the ends are doubled back upon their levers as at 247
and so practically fill the spaces between the said leveis 245 A yoke 248 19
secured to the top of plate 3 and extends over and embraces the said levels 245
01 ends 247 to limit then upward movement and to prevent displacement of the
loveis, sidewise during the operation of the machine Normally, the said ends 247
lie out of the path of the carriage but are moved into the path of said cantage
o a part secured thereto (adjustably or otherwise) upon the depression of the
corresponding key The universal bai 120 is extended over said levers 245 in
position to be locked thereby and the thow of such bai by said keys 16 such as
to move the rack bat 118 to a position below the fixed tooth 117, thereby releas-
ing the carnage from the control of the escapement and permutting it to move
to the left under the influence of its diving spring 132 until stopped as in a
manner now to be described The carnage 47 18 provided with a shatt 249 fast
thereto and parallel to the duection of motion thereof The end of said shaft on
10d 249 16 provided with a collar or stop 250, into the path of which the ends 247
of the levels 245 air moved whenever the coresponding key is depressed as
indicated by the dotted line din Figure 2 Rod 249 oi collar 250 may be adjust-
able to cause the anest of the cauage at different points The key 237 and its
lever 245 are at the left of the group of carriage release and stop keys and the
other heys 238 to 244 inclusive and their corresponding levers are disposed at
the right of said key 237 and its leve in the order of units, tens, hundreds,
thousands, and so on, beginning at the left with units
The stops 247, as shown, are of uniform width and this width preferably 18
equal to the uform letter space feed of the paper calliage, that is to say, the
pitch or spacing apart of the teeth of rack bai 118 The stops 247 and the lug
or colla 250 are so arranged relatively to each other, and the rach 191 18 80
aanged on the camage with relation to pinion 195 and the pinion 190 is in
such ielation to the gears 178 when in the position shown in Figure 5, that the
stop 247 coresponding to the "millions" key 244 arrests the lug or stop 250 in
such position that on the release of the said kev 244 and the fall of the stop 247,
the paper carnage and rack 191 will move for waid one letter space feed and the
1ack 191 will actuate the pinion 195 and thus, by the described connections, will
move the pinion 190 into mesh with the gear 178 corresponding to the "millions'
number wheel or that at the left at Figure 5 Similarly whenever the carnage
18 released by depressing any other of the keys on the levels 245 the correspond-
ing stop 247 will be raised into the path of the lug 250 and will arrest the stop
and calliage in such position that on the release of the release key the canage
will move forward one step and so also of the dive pinion 190; for example if
the key 240 be depressed while the paper caulage 18 in such position that the
rack 191 is not in mesh with pinion 195 the paper cauage will be released and
will move forward under the influences of its diving spring until anested by the
stop comesponding to key 240; but the tack 191 will mesh with the pinion 195
and thus move the pinion 190 axially from the time the stop 250 has passed
the stop 247 on the "millions" lever 245; in such case the teeth of pinion 190
pass between the teeth of the gears 178 corresponding to the millions, hundredths

page_text: of thousands, tens of thousands, and thousand's adding wheels in the manner in
which one may pass the separated or spread fingers of one hand between the
separated or spread fingers of the other hand and is arrested finally in mesh with
the pinion 178 corresponding to the hundreds wheel From this it is evident
that the stop 247 corresponding to the millions key 244, the lug 250, the rack 191
and pinion 196 should be so related to each other that the rack will engage with
the pinion at least as early as the time of stoppage of the carriage by the said
millions stop 247.
It is obvious that the mechanism for moving the pinion 190 step-by-step in an
axial duection may be arranged to move said pinion more than one step before
bringing it into mesh with the first gear 178 (at the left-hand side in Figure 5)
without in any degree departing from my invention.

It results from the described construction and arrangement of the carriage
release and stop keys that the carriage may be stopped in position to begin the
wiiting of any number in its proper position upon the paper relatively to the
decimal point or the numbers that have been properly witten before
example, if one has a number to write beginning in the hundreds of thousands
and the carriage is not moved sufficiently far to the left to begin the number
in the proper position the key 243 19 depressed, thus releasing the carriage as
described and allowing it to move towards the left until the stop 250 is arrested
by the raised end 247 of the lever 245 canving said kev 243, whereupon the said
key is released and the rack bai 118 is re-engaged with the movable escapement
dog 120 and the carnage moves one letter space further to the left
The finge
kev 149 is to be depressed and held down during the writing of the numerals or
digits of the said number or amount beginning in the hundreds of thousands,
and then to be released before the beginning of writing other matter, as will he
understood If the next amount to be witten in the column begins in the
hundreds, the key 240 18 to be depressed as described and the carriage will be
moved forward and will be stopped and on release of key 240 will move to posi-
tion to bing the hundreds to be witten under the hundreds already written and
in proper relation to the decimal point In other words, the key 240 18 associated
with that particular adding wheel which is always employed for adding figures
in the hundreds column Each of the keys 238 to 244 may be termed a select-
ing key" since when operated it automatically determines which wheel is to be
operated by any of the figure keys when the carriage comes to iest subsequently
to manipulation of the selecting key, that is to say, when any of the selecting
keys 18 depressed it operates to release the carnage and determine its stopping
point, while at the same time it bungs the adding mechanism into such relation-
ship with the figure-type keys that the particular adding wheel represented by
such depressed key will next be operated upon by any selected figure-type kev
when subsequently operated simultaneously to pint the desued numeial and
cause the quantity represented thereby to be added by the computing mechanism.
It will be observed that the present invention differs in principle from what
may be termed a combined adding and recording mechanism, in that my complete
machine combined typewriter and adder is capacitated to do the work of the
ordinary typewriting machine and also to do the work of an adding machine and
also to do the work of an adding and recording machine, and that it also goes
beyond any of these three machines in that typewriting may be done upon one
part of the lines, tabular work upon another part of such lines, and the summa-
tion of the tabulai work he secured in the adding mechanism, the adding mechan-
18m preferably not coming into operation until the paper calage or other car-
iage of the typewriting mechanism has reached a given on piedetermined point
in its forward motion or have se The class of adding or recording mechanisms
referred to above 18 that wherein the machine is provided with type representing
the nine digits and the naught and with keys and mechanism whereby the num-
bers added up are also recorded upon a strip or sheet of paper but are not pro-
vuded with letter type and letter keys; such adding and recording mechanisins

page_text: are not adapted to do typewriting work (like words and sentences), and are
furthermore lacking in what, in some aspects of my invention, is an essential
element of the operation, to wit, the picking up, so to say, of an adding mechanism
by the carriage of the typewter when it has reached a predetermined point
in its forward traverse; or otherwise expressed, the throwing on bringing of an
adding mechanism into operative relation with the paper cauer and printing-
mechanism at a predetermined point in the line of print, such adding mechanism
normally being disconnected from on out of operative relation to said carrier
and pinting mechanism
It will be noted that, insofar as one featuro of my invention is concerned, I
provide a journaled shaft intermediate the typewriter carriage and the carriage
for the diver 190 and gear the shaft continuously with one carriage and dis-
continuously with the other carriage: in the instance shown in the drawings, the
typewriter caniage is the one that is discontinuously geared with the shaft 196
The particular embodiment of my invention illustrated in the diawings and
above described comprises a treble-case typewriting machine, but it is obvious
that my adding mechanism and operating means therefor are applicable as well
to "double" and "single" case machines, and so also of other features of my
invention It 18 also obvious that the number carrying peripheries of wheels 164
165 may be wholly within or inside the teeth of gears 179 180 and that pinion 190
may then co-act directly with the gears 179, leaving the carrving function alone
to the devices shown as connecting pinion 190 and the number wheels Also
many other changes in parts, features and combinations may be made without
departing from the spirit of my invention
Furthermore, the specific form of the adding mechanism shown herein may be
combined with any suitable style or construction of typewriting mechanism to
secute the ends sought In some aspects of my invention as herein claimed, other
forms or embodiments of adding mechanism working upon different principles
may be substituted for the adding mechanism of the claimed combination without
departing from my invention insofar as it relates to combined adding and type-
writing machines
Mr improvements in the typewriting machine proper and in the adding
machine per se, are made the subject-matter of separate divisional applications
