page_text: frame 1. When at rest the free or type ends of the type arms are supported by
a semicircularly bent strip 19 secured to the frame 1. When a key 2 is depressed
it actuates its fever 11, 12 and type lever 15, 16 to throw the type end with the
required type against the platen or roller 20.
The roller 20 is carried by the carriage 21 which as known is exposed to the
influence of a spring drum or actuator 22 (Fig. 3) which in connection with the
feed rack 23 (Fig. 7) and the dog to be hereafter described gives a step by step
motion to the carriage. The carriage is hinged at its rear to a bar 24 secured to
frame 1 and along which bar the carriage can reciproente, the front of the carriage
having a roller 25 adapted to travel on bar 26 secured to said frame 1.
The carriage platen or roller 20 is not fixedly journaled in the carriage but said
roller is made shiftable independently of the carriage, so that while the carriage
remains on its tracks 24 and 26 the roller can be shifted to bring the paper on the
roller to the printing line of one or another of the plurality of type on the
type bar.
The shaft A (Figs. 1, 4 and 7) of the roller 20 is journaled in a frame 27
appropriately called platen frame jointed at 28 to arms 29 fixed to the shaft 30
which can turn or swing in suitable bearings on the earriage. To the shaft 30 is
fixed a toothed collar 31 (Figs. 1 and 3) engaged by a toothed collar 32 mounted
loosely on the shaft 30 and exposed to the pressure of a spring 33 coiled loosely
about the shaft and braced against a suitable part of carriage 21.
The rotary collar 32 has eyes or perforations 34 (Fig. 3) for the engagement of
a key or tool to wind or turn collar 32 to bring spring 33 to the proper tension,
this spring tending to turn rod or shaft 30 for swinging arms 29 upward so as to
aid or ease the lift of the platen or roller 20, the tension of this spring 33 however
not being sufficient to enable the spring unaided to lift the roller.
The platen-frame 27 supporting the shaft of the roller has a wheel or disc 35
journaled on an arm 36 depending from said frame, said wheel 35 traveling on the
track or bar 37 extending across the machine. Said track 37 is supported on
arms 38 (Figs. 4 and 14) fixed to a rock shaft 39 (Fig. 4) so that by rocking said
shaft 39 the arms 38 with track 37 will be swung to raise or lower wheel 35 with
frane 27 and roller 20. To the rock shaft 39 are fixed arms 40 (Fig. 4) engaged
by arms 41, one such arm 41 extending from each of the keys 3 and 4 already
named, and which keys move independently of one another.
The key 4 when depressed will raise track 37 and when said key 4 is then
released the track 37 will full back to its starting point, while when key 3 is
depressed said key will not only raise the track but will alao be automatically
locked to hold the track elevated until said key is unlocked. This key 3 has at its
front vertical face or edge a notch 42 (Fig. 4) into which on the depression of this
key snaps a detent or lock 43 fixed to rock shaft 44. To this rock shaft 44 is fixed
a releasing arm 45 (Fig. 7) extending toward the front vertical edge of key 4, said
last named key being so shaped that on the depression of key 4 said edge will
press against arm 45 to swing the latter with shaft 44 and detent 43 into position
to release key 3. The key 4 thus serves not only for raising the track 37 with
roller 20 but also for unlocking key 3 as required.
The rock shaft 44 is exposed to pressure of spring 46 tending to move detent 43
to locking position.
The ribbon spools B B are provided with on ink ribbon 47 passing by the ribbon
guide 48 which ribbon guide has its upper portion where the ribbon passes made
forked, the type bar when printing being made to strike between the tines of this
fork to move the ribhon toward the roller. As the roller is shifted up or down,
the ribbon guide with the ribbon is similarly shifted to keep the ribbon in proper
position relatively to the roller or to the printing line. This ribbon guide 48 as
seen in Figs. 7 and 8 is jointed at 49 to an arm 50 of lever 50 51, fulcrumed at 52
to an arm 53 rigidly fixed to track 37. As the track 37 rises and falls to shift the
paper roller up or down, said track carries with it the arın 53 and fulcrum 52 80
that lever armi 50 with guide 48 is shifted with the track 37.

page_text: The lever arm 51 is jointed at 54 to link 55 jointed at 56 to the plate or
support 57 carrying the feed dog to be presently described. As said plate 57
nscillates back and forth to give the feed dog the well known reciprocation for
permitting the step by step feed of the paper carriage, said plate by means of
link 55 will oscillate fever 50, 51, so that the ribbon guide 48 which normally resta
below the printing line to expose the latter to view, will during the printing stroke
of the type bar be brought up to the printing line to cause the ribbon to be struck
by the printing type bar.
The ribbon guide 48 is thus moved by two means, one by means of its connection
to track 37 for accompanying the paper roller as it is shifted, another by means of
its connection to the feed dog support 57 for moving to and from the printing
line.
The feed dog support 57 is supported on arms 58 (Fig. 7, 8 and 14) jointed
at 59 to arms 60 fixed to rock shaft 61. This rock shaft 61 has a fixed toothed
collar 62 engaged by loose toothed collar 63 exposed to pressure of spring 64 8
that the tension of the spring tends to move arms 58 forward. These arms 58 are
also connected to the universal bar 65 arranged in semicircular form back of the
notches of the semicircular or curved plate 18, so that when a type bar moves to
the printing position, the projection 66 (Figs. 7 and 8) on such type bar will press
back the universal har 65 against the pressure of spring 64, so as to give arms 58
with support 57 a backward stroke. On the return of the type bar from the
position shown in Fig. 8 to that shown in Fig. 7 the spring 64 will swing shaft 61
to move arm 60 with support 57 forward.
The feed dog comprises the teeth CD D', (Figs. 7, 8, 11, 12 and 13) the
tooth C being slidable as known so that when this tooth C is thrown into engage-
ment with the feed rack 23 the paper carriage is moved a step by the motor 22,
while the teeth D D' are each non slidable so that when either of these teeth D
or D' is in engagement with the rack 23 the carriage is held against the action of
the motor. As seen there is a non slidable tooth on each side of the slidable
tooth C. The rack 23 when in the position shown in Figs. 7 and 8 is normally in
engagement with the slidable tooth C (Fig. 7) aud on a type arm moving to the
printing position (Fig. 8) a non slidable tooth is brought into engagement
with the rack so that during this printing movement of the type arm the rack with
the carriage remains stationary, the slidable tooth C at the same time being freed
so as to snap back a step. On the return of the type arm the slidable tooth C
again engages the rack and said tooth C with rack 23 is now moved a step forward.
When the rack 23 has been shifted to the position shown at the left-hand side of
Fig. 13 said rack is normally in engagement with a non slidable tooth D and
during the printing movement of the type arm the slidable tooch C is brought into
engagement with the rack as seen at the right hand in Fig. 13 so that during this
printing movement the rack with the carriage moves a step forward, while during
the return movement of the type arm the non slidable tooth D is brought back into
engagement with the rack so that the latter now remains stationary, the slidable
tooth C at the same time being freed to snap a step backward.
By setting the rack 23 the paper carriage can by these means be made to move
a step forward either during the return stroke or during the printing stroke of the
type arms as desired as will now be described.
The rark 23 being eccentrically mounted or fixed to rod 67 (Figs. 8, 9 and 13)
a half turn of this rod by means of finger button 68 will shift the rack to the
position shown in Fig. 8 or as shown at the left-hand side of Fig. 13 as required.
The rod 67 has its bearings in a suitable frame 69 supported by arms 70 (Figs. 1, +
and 7) pivoted or fulcrumed to carriage 21, so that a depression of the forward
end of either arm 70 will lift the rack out of engagement with the dog. One
arm 70 extends forward at one side of the carriage and is provided with a finger
piece or key 71 (Fig. 1) for readily depressing the forward end of said arm. The
other arın 70 extends forward at the other side of the carriage and terminates
under a lever arm 72 (Fig. 1) fulcrumed to the carriage at 73 and provided with

page_text: a handle or finger piece 74 (Figs. 1 and 3) which when suitably actunted will
depress arm 72 with the contiguons arm 70 to lift rack 23 out of action.
The rod 67 is not only rotary but also longitudinally movable in its bearing or
frame 69 and said rod has wings or lugs 75 (Figs. 9 and 10) fixed to the rod and
held by spring 76 in engagement with shoulders or recesses on frame 69. When
the rod 67 is moved longitudinally against the action of spring 76 the wings 75 are
freed or moved away from the locking shoulders so that the rod 67 can be given a
half turn before the wings 75 are again allowed to lock the rod 67 against
rotation.
The slidable tooth C already named is supported by a slide arm 77 (Fige. 11
and 12) having slots engaging the pivot 78 and pin 79 the pivot 78 being fixed to
the support 57 and the pin 79 being secured to the arm 80 straddling the arm 77,
said arm 80 being pivoted at 78 but not capable of sliding. Said pin 79 is guided
in a slotted arm 81 extending from support 57. The spring 82 braced against
support 57 engages the arm 83 depending from slide 77 and anid spring not only
tends to move slide 77 backwards but also tends to swing said slide with arm 80
upwards to hold the teeth C D D' in engagement with the rack.
From slide 77 extends a finger 84 under a finger 85 (Fig. 7) fixed to a rock
shaft 86, the spring 87 (Fig. 14) of which tends to turn the shaft 86 to hold
finger 85 up out of contact with finger 84. When however the shaft 86 is rotated
so that the finger 85 depresses finger 84 with teeth CD D¹ to move the latter out
of gear with rack 23, the paper carriage is free to be moved by motor 22.
It is thus noticed that the carriage can be freed either by lifting rack 23 out of
gear, or by depressing the dog teeth C D D' out of gear.
The shaft 86 can be rocked to depress the dog by means of key 5 already
noticed, said key having a horn or arm 89 (Figs. 3 and 4) jointed at 90 to
lever 91, 92, fulcrumed at 93 and engaging arm 94 fixed to rock shaft 86 so that a
depression of key 5 will turn shaft 86 against the action of spring 87.
To the rock shaft 86 is also secured a stop arm 95 (Figs. 3, 7 and 13) which can
be adjusted or fixed along the shaft by clamp screw 96. When the shaft 86 has
been rocked against the action of spring 87, the arm 95 has been thrown forward,
to come into the path of the slide rod 97 (Fig. 3) supported in eyes or ways fixed
to carriage 21 and exposed to the pressure of a spring 98 suitably braced against
any part of the carriage and which spring tends to force the rod 97 forward or in
the direction in which inotr 22 tends to move the carriage. When the shaft 86
has been rocked to free the dog CD D¹ and the carriage in consequence rushes
forward, the sliding rod 97 becoming arrested by stop arm 95 will cause the
earringe 21 to be gradually arrested by the compression of spring 89, so that the
carriage will not be excessively jarred."
The carriage 21 is provided as known with an index 99 traveling over scale
plate 100 and said carriage also has a lip 101 (Fig. 1) which when the carriage
nears the end of its forward travel will first press on shoulder E and then on the
somewhat higher shoulder E' said shoulders being formed by a step shaped piece
or lug secured to rock shaft 102 journaled in irame L. To this rock shaft 102 is
fixed an arm 103 (Fig. 7) normally held or swung back by spring 104, but when
the carriage has passed far enough forward for its lip 101 to press on shoulder E,
the arm 103 has been swung far enough forward for its free end or the pin 105 at
said end to have passed over the forward end of bell hammer lever 106, thus first
raising said hammer and then allowing it to drop for sounding bell 107, whereby
the approach of the end of a line is announced as known.
Passing to the limit of its forward travel the carriage will bring its lip 101 over
the higher shoulder E¹ so as to rock the shatt 102 for swinging arm 103 further
forward into contact with lip 108 projecting from the locking bar or rod 109
supported on swinging arms 110 carried by shaft 111 supported by frame 1. The
bar 109 being thus swung forward by the extreme forward swing of arm 103, said 4
bar 109 will catch or come to rest under the hooks 112 projecting from the type
keys 2 thereby locking said type keys against further action until by the setting

page_text: back of the carriage the shoulders E E with rock shaft 102 and arm 103 are free
to be swung back by spring 104.
The lugs or shoulders E E¹ are adjustable along rock shaft 102 so that the
forward travel of the carriage can be arrested at various points according as said
shoulders E E' are set or adjusted. The adjustment of the shoulders E E' can be
indicated along the scale plate by index F secured to said shoulders. When
adjusted the shoulders can be held in place by means of the toothed bar 113
(Fig. 1) secured to rock shaft 102, said shoulders having a locking pin 114
actuated by handle 115 for engaging or disengaging with the rack 113. The
handle 116 enables the shoulders when free to be readily slid or moved along
shaft 102. The back set of the carriage can also be determined by a stop 117
(Fig. 1) adapted to be adjusted and clamped on track 26 by a jam screw 118, the
position of this stop being indicated by its index 119 along the scale plate. The
carriage has a depending stop 120 (Fig. 2) adapted to strike against stop 117 on
the carriage being set back. This stop 120 depends from an arm 121 (Fig. 1)
jointed to the carriage at 122 and engaging at its free end with the arm 123 of
lever 123, 124, fulcrumed to the carriage at 125. Should it be desired at any
time to set the carriage back beyond the point determined by stop 117 without
moving said last named stop, the depression of lever arm 124 will raise stop 120
sufficiently for clearing stop 117, and on releasing lever 123, 124, the stop 120
will drop back to engaging position, but a movement of the carriage in the
direction of its feed will bring the stop 120 into contact with the cam face 117*
of the stop 117 which will raise said depending stop 120 and allow a free
movement of the carriage in the direction of its feed.
The ribbon spools B B' already named can be rotated so that the ribbon winds
onto either one or another of the spools during the operation of the machine, or if
desired said spools can be left stationary during such operation. To the shaft of
each of said spools is secured a ratchet wheel 126 (Figs. 2 and 4) one or another
of which can be engaged by a spring finger 127 forming pawls. These spring
fingers are each secured to a lever 128 fulcrumed at opposite side plates of frame 1
and connected at their upper ends by a bar 129 connected to the universal bar 65.
When this universal bar oscillates back and forth as already noticed it oscillates
levers 128 with the spring fingers 127. These fingers 127 normally tend to clear
the ratchet wheels 126 but said fingers can alternately be moved to an engaging
position by spring fingers 130 located at opposite arms of the lever 131 (Fig. 2)
centrally fulcrumed at 132. By swinging lever 131 one or another of its arms
will be raised so that either the pawl for the ratchet wheel of a spool B or that
for the ratchet wheel of spool B will be pressed into engaging position to rotate
its spool as said pawl oscillates with its respective lever 128. The spool rotated
by its pawl winding or taking up the ribbon will naturally unwind the ribbon from
the other spool which is meantime left free or loose from its pawl although said
last named pawl oscillates in time with the other pawl. By throwing the lever 131
to an intermediate position the spring fingers 130 will not be able to press either
of pawls 127 to engaging position so that the spools B B' will both remain at rest
even while levers 128 oscillate the pawls 127. The fingers 130 are shown
arranged in pairs, one finger of each pair also serving as a detent for its toothed
wheel 126.
The lever 131 can be locked in its two extreme positions or in its intermediate
position by means of notches 133 (Fig. 4) in frame 1; into one or another of said
notches an arm or shoulder of said lever 131 can engage for setting the lever in
one of the three named positious.
The spools B B' have their shafts mounted in plates 134 (Figs. 4 and 7) having
legs 135 adapted to slip into suitable pockets or seats on frame 1, said plates
being provided with spring catches 136 adapted to lock under shoulders 137 on
said frame. By moving catches 136 to releasing position the plates 134 with the
ribbon spools can be pulled up out of place to be removed from the machine.
The shafts of the spools have finger buttons 138 (Figs. 2 and 4) projecting

page_text: through suitable holes in frame 1 so as to be within reach for turning the spools by
hand. The plates or supports 134 carry the bearings 139 for the rollers over
which the ink ribbon is guided to the already named ribbon guide 48.
The paper roller or platen 2 is shown in Figs. 1 and 15 with its shaft A
extending through platen-frame 27. If this roller is to be made readily removable
from frame 27 its shaft A is not allowed to extend through frame 27, but as seen
in Fig. 16 said shaft A stopping short of platen-frame 27 is supported in a
supplemental platen-frame 140 having logs or projections 141 adapted to sit or
drop into suitable seats on platen-frame 27. The platen-frame 27 has at each
side short shafts A' pressed inward or toward one another by springs. To each
shaft A' is fixed a disc 142 having a central aperture into which can sit the ends
of shaft A, said discs also having an eccentric eye or eyes 143 adapted to he
engaged by an eccentric pin 144 on plate or disc 145, one such disc 145 being
fixed to each end of shaft A. The shafts A A¹ being thus locked together the
rotation of hand wheels G or of one of said wheels will rotate platen 20 in Fig. 16
the same as when one of the wheels G (Fig. 15) fixed to shaft A is rotated. By
spreading or pulling apart the shafts A' (Fig. 16) the shaft A with its discs 145
is freed from discs 142 so that the supplemental platen-frame 140 with platen 20
can be readily lifted out of platen-frame 27, leaving the latter connected to the
carringe by the pivots or screws 28.
Should it be desired to remove the frame 27 it is simply necessary to unscrew
the pivots 28 by which said frame 27 is jointed to the swinging arms 29.
When the roller of Figs. 16 and 17 is removed from the frame 27 said roller is
locked against rotation by the detent 146 (Fig. 17) being moved by spring 147
into engagement with teeth on one of the discs 145. Should said roller with partly
completed writing thereabout be removed from the machine said writing with the
roller will thus be locked so that the writing can continue on without derangement
when the roller is dropped back into its place in frame 27. Dropping the roller
into its place in frame 27 will unlock the detent 146 as a stud 148 projects from
frame 27 at such a height that when the roller frame 140 is down in its place in
frame 27 said detent 146 rests on said stud or releases 148 so as to be held up
away from the teeth on the adjacent disc 145, leaving said disc with roller 20 free
to rotate.
The band wheels G or G¹ enable the roller 20 to be turned either back or
forward, as the detent or spring 149 (Fig. 5) has its engaging or free end so
rounded that it locks the ratchet wheel 150 (Figs. 5, 15 and 16) on shaft A or on
a shaft A against accidental rotation but not against its being turned either way
by wheels G or G'. The wheel 150 can also be turned for feeding the paper
forward during writing by means of the horizontally swinging lever 151 (Figs. 1
and 5) fulcrumed at 152 to carriage 21 and having a pin 153 engaging or slipping
into the booked end of slide 154 suitably slotted so as to be guided while sliding
by pins 155 on frame 27. On this slide swings a pawl 156 having a tooth 157 and
pressed by spring 158 toward ratchet 150. As the slide 154 moves back its pawl
tooth 157 engages ratchet 150 to rotate the latter with roller 20 forward while
on the return of the slide the tooth 157 rides over ratchet 150 without engaging
the latter.
The tooth 157 in its reciprocations can be made to rotate the ratchet 150 the
space of one tooth or of two teeth as desired. From the pawl 156 of tooth 157
depends a lip 159 (Fig. 6) into a slot in a slide 160 capable of being set back or
forward by button 161. In the position of parts shown in Fig. 6 the lip 159 is
down in the slot in slide 160 so that on the back stroke of pawl 156 its tooth 157
will at once engage wheel 150 to rotate the latter during the entire back stroke
of the pawl. If, however, slide 160 is moved back its unslotted forward portion
will lift lip 1.9 to raise tooth 157 out of engaging position so that the latter will
not engage wheel 150 until after the pawl 156 has moved some distance back, this
partially lost backward motion of the pawl resulting in a diminished rotation of
wheel 150. In Fig. 6B the slide 160 is shown moved back and the pawl 156 out

page_text: of engagement with the ratchet 150, in which position of parts the platen is free-
to he turned either forward or backward.
The lever 151 as already noticed when oscillated will reciprocate slide 154, and
the slide 154 when free is moved forward by a spring 162 (Figs. 5, 6 and 15).
suitably supported by a pin 163 on frame 27 and braced against shaft A.
About the roller 20 extends a guard plate 164 which as seen in Fig. 8 extends
forward close to the printing line so as to hold the sheet for writing close to its
bottom edge. Through slots or openings in this guard plate extend the rollers 165
(Figs. 4 and 15), their shafts 166 being supported by arms 167 extending from
toothed collars 168 loosely mounted on shafts 169 fixed in frame 27. The toothed
collars 168 are engaged by loose toothed collars 170 exposed to the tension of
springs 171 braced against collars 172 fixed to shafts 169. The tension of the
springs 171 is such that the collars 168 with arms 167 press the rollers 165 against
the roller 20 to keep a sheet smoothed about the roller while being written on.
The winding or turning of collars 170 will regulate the spring tension.
With reference to the actuation of the bell hammer lever 106 by the arm 103.
(Figs. 1, 4 and 7) it may be noted that said arm in its forward swing actuates
the hammer lever, but does not actuate the latter when returning, said arm when
swinging forward pressing by its pin 105 on the inclined lip 173 which is pivoted
to the hammer lever at 174 so as to he incapable of yielding downwards
independently of the hammer lever when the pin 105 of the arm 103 presses on
this lip 173 in the forward stroke of such arm. Said lip, however, can yield
upward independently of the hammer lever so that the pin 105 of the arm 103
on its return swing in passing under the inclined lip 173 will lift the latter
independently of the hammer lever, said lip after the arm 103 has passed back
dropping or swinging down to rest on the hammer lever 106 so that the next
forward stroke of the arm 103 will again depress lip 173 with lever 106.
As the type arms are pivoted near one end and have their short arms pivoted
to the longer arms of the crank levers 11, 12, said crank levers being fulcrumed
at the ends of their shorter arms and being pivoted at their angles to the keys 2,
the parts are in position to cause a slight depression of the key to effect a long
and swift stroke or sweep of the type end of the type arm, so as to obtain a clear
aud perfect impression. As the crank levers 11, 12, are pivoted directly to the
type arms and to the keys the construction is made simple and unnecessary parts
with liability of loss or disorder are avoided.
In front of the movable ribbon guide 48 is fixed a guide or fork 175 between
the tines of which the type end of the bar is properly guided at the moment of
printing or striking.
The stop 95 (Figs. 3 and 7) when set by its screw 96 so as to arrest the
carriage at a certain distance before the extreme end of its possible travel, can
be practically utilized for certain kind of writing, as for example in making out
a bill where a column of figures has to be placed at or near the right hand edge
of the sheet, the stop 95 when brought into action by the releasing rock motion
of the shaft 86 serving to arrest the carriage each time at the point where the
figures on successive lines have to be started to fall into the required column.
The lip 159 (Fig. 6) of pawl 156 already named when said pawl is in its
backward position, will abut or nearly abut against an edge of frame 27 so that
said pawl is prevented by the contact of lip 159 with the edge 175 (Fig. 6A) of
frame 27 from lifting or jumping out of engagement with wheel 150, thereby
locking said wheel when the pawl has reached the end of its back stroke, the
wheel 150 with the platen being thus prevented from rotating by accident or by
its own impetus beyond the required degree.
Having now particularly described and ascertained the nature of the said inven-
tion and the manner in which the same is to be performed, I declare that what I
claim is :-
1 A true-writing machine comprising a frame 1 provided with bars 24 and 26

page_text: fixed respectively to the rear and to the front of the frame, a carriage frame 21
having at its rear portion eyes made to clasp and slide on said rear bar; said
carriage frame being extended forward to rest on said front bar, a platen frame set
