effect this I dispense with the ordinary inking tape or ribbon now in common use
and cause each type (which is carried as usual at the end of a lever arm) to be inked
by a small inked roller passed over its face each time that it is used.
The axes of the lever arms I range at distances apart in a segment of a circle
preferably somewhat larger than a semicircle with the lever arms turning in planes
radial to the centre of this circle so that they may strike radially onto the central

traversed a distance end wise after the depression of each finger key and is at the
end of each line brought back to its normal position and turned a short distance
on its axis as is usual.
The cylinder carrying the paper may be at the top of the machine and the circle
in which the axes of the lever arms are ranged be in a vertical plane parallel with
the longitudinal axis of the cylinder and not far from it and the finger keys may
be placed at the front so that the operator faces the side of the cylinder which is
struck by the type and has an uninterrupted view of this cylinder the type lever
arms being normally at right angles to the cylinder or approximately so and not
obstructing his view.

Or in place of the cylinder being at the top it may be at the bottom and the
circle in which the axes of the levers are ranged be in a horizontal plane and so
arranged that the levers strike down on to the top of the cylinder.
With this construction their would be an uninterrupted view of the top of the
cylinder from the opening between the two ends of the circular segment-and the
finger keys' might be placed at this point.

page_text: This construction is well adapted for being used when the type arms have
movement given to them by electro magnets and the finger keys operate contact
mechanism for passing electric currents to the magnet coils.
Each time that any one or other of the type lever arms is used I cause the small
inking roller on its end which is to ink the type to be drawn over the face of the
type before the lever starts into movement and I also cause the roller to be drawn
over an inked surface so that the roller may be replenished with ink and similarly
when the type lever has made its stroke and returned back to its normal position
I cause the ink roller to again pass over the face of the type.
To give these movements to the ink roller and to the type arm-the axis of the
inking roller may be carried by an arm jointed to a slide which can be moved
end wise to and fro in fixed guides-and the arm may be pressed downwards by a
spring to cause the roller to bear constantly either upon the face of the type or
upon the inked surface which supplies ink to the roller.
The slide is drawn in one direction each time that the finger key used for operating
it is depressed and is drawn back in the opposite direction by a spring when the
finger key is released or vice versa
The slide may have a slotted link attached to it and a continuation of the type arm
past the type arm axis may carry a pin to enter this slot.
Movement is transmitted to the slide or link on the depression of the finger key
either by levers and links or by the action of an electro magnet. Each finger key in
this case being used to complete an electric circuit through the coils of one or other of
the magnet coils each time that it is depressed.
By the movement of the slide the inking roller is carried away from in front of the
face of the type on the type arm the type arm remaining at rest until the pin above
mentioned is at the end of the slot the type arm is then turned on its axis and the
type carried by it made to strike against the paper-When the finger key is released
the type arm and slide are brought back by a spring or springs to their normal
position.
The same action takes place if the slide is moved endwise by a lever acted on by an
electro magnet.
In order that the inked surface over which the ink rollers are made to roll each
time that they are drawn back may be kept replenished with ink. I make it in the
form of a ring which may be revolved from time to time or with a step by step
motion as the finger keys are depressed so as to cause all parts of its surface to be
moved past a roller which bears upon it and which is kept constantly supplied
with ink.
In order that a variety of type may be used in the machine each type arm is made
to carry at its end a small roller the circumference of which has three four or more
different kinds of type projecting from it. The roller has a small toothed wheel on its
axis and the toothed wheels of all the small rollers on the type arms are made to gear
with a toothed quadrant so that by moving the quadrant end wise more or less in one
direction or the other any of the different types can be brought into use-all the type
being changed simultaneously.
The cylinder which carries the paper that is to be printed on may be traversed to
and fro and turned a distance after the completion of each line in any ordinary way.

page_text: I, ALFRED HENRY HUTH, of Bolney House, Ennismore Gardens, in the County of
Middlesex, Gentleman, 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 :-
My improvements have mainly for their object to so construct type writers that the
writing as it progresses shall be fully exposed to the view of the operator. To effect
this I dispense with the ordinary inking tape or ribbon now in common use and cause
each type (which is carried as usual at the end of a lever arm) to be inked by a small
inked roller passed over its face each time that it is used.
The axes of the lever arms I range at distances apart in a segment of a circle
preferably somewhat larger than a semicircle with the lever arms turning in planes
radial to the centre of this circle so that they may strike radially onto the central
point. The paper to be printed on is carried as usual by a cylinder which is traversed
a distance endwise after the depression of each finger key and is at the end of each
line brought back to its normal position and turned a short distance on its axis as is
usual.
The cylinder carrying the paper may be at the top of the machine and the circle in
which the axes of the lever arins are ranged be in a vertical plane parallel with the
longitudinal axis of the cylinder and not far from it and the finger keys may be placed
at the front so that the operator faces the side of the cylinder which is struck by the
type and has an uninterrupted view of this cylinder the type lever arms being
normally at right angles to the cylinder or approximately so and not obstructing his
view.
Or in place of the cylinder being at the top it may be at the bottom and the circle
in which the axes of the levers are ranged be in a horizontal plane and so arranged
that the levers strike down on to the top of the cylinder.
With this construction there would be an uninterrupted view of the top of the
cylinder from the opening between the two ends of the circular segment-and the
finger keys might be placed at this point.
This construction is well adapted for being used when the type arms have
movement given to them by electro magnets and the finger keys operate contact
mechanism for passing electric currents to the magnet coils.
Each time that any one or other of the type lever arms is used 1 cause the small
inking roller on its end which is to ink the type to be drawn over the face of the type
before the lever starts into movement and I also cause the roller to be drawn over an
inked surface so that the roller may be replenished with ink and similarly when the

page_text: type lever has made its stroke and returned back to its normal position I cause the
ink roller to again pass over the face of the type.
To give these movements to the ink roller and to the type arm-the axis of the
inking roller may be carried by an arm jointed to a slide which can be moved
end wise to and fro in fixed guides-and the arm may be pressed downwards by a
spring to cause the roller to bear constantly either upon the face of the type or
upon the inked surface which supplies ink to the roller.
The slide is drawn in one direction each time that the finger key used for
operating it is depressed and is drawn back in the opposite direction when the
finger key is released.
The slide may have a slotted link formed with or attached to it and a continuation
of the type arm past the type arm axis may carry a pin to enter this slot.
Movement is transmitted to the slide or link on the depression of the finger key
either by levers and links or by the action of an electro magnet. Each finger key in
this case being used to complete an electric circuit through the coils of one or other
of the magnet coils each time that it is depressed..
By the movement of the slide the inking roller is carried away from in front of the
face of the type on the type arm the type arm remaining at rest until the pin above
mentioned is at the end of the slot the type arm is then turned on its axis and the
type carried by it made to strike against the paper. When the finger key is released
the type arm and slide are brought back by a spring or springs to their normal
position.
The same action takes place if the slide is moved endwise by a lever acted on
by an electro magnet.
In order that the inked surface over which the ink rollers are made to roll each
time that they are drawn back may be kept replenished with ink, I make it in the
form of à ring which may be revolved from time to time or with a step by step
motion as the finger keys are depressed so as to cause all parts of its surface to
be moved past a roller which bears upon it and which is kept constantly supplied
with ink, or is itself an ink reservoir.
In order that a variety of type may be used in the machine each type arm is
made to carry at its end a small roller the circumference of which has three four
or more different kinds of type projecting from it. The roller has a small toothed
wheel on its axis and the toothed wheels of all the small rollers on the type arms
are made to gear with a toothed quadrant so that by moving the quadrant endwise
more or less in one direction or the other any of the different types can be brought
into use all the type being changed simultaneously.
The cylinder which carries the paper that is to be printed on may be traversed
to and fro and turned a distance after the completion of each line in any ordinary
way.
Figures 1, 2 and 3 of the drawings annexed shew various views of a type writer
constructed according to my invention.
Figure 1 is a front elevation with many of the parts removed-Figure 2 is a
vertical section with the upper part in elevation and Figure 3 a plan view mainly in
section.
Figure is a plan view and Figure 5 a vertical section of a modification in which
the cylinder that carries the paper is at the bottom of the machine and in which
electro magnets are used for giving movement to the parts.
Figure 6 shews how mechanism such as shewn at Figure 5 for giving movement to
the type arms can be operated by finger key levers similar to those shewn in Figures 1,
2 and 3.
In Figures 1, 2 and 3 A is a cylinder by which the paper to be printed on is
carried as in other type writers-B B are lever arms carrying the type at their ends-
they turn on axes B¹ in planes radial to a central point A so that any one or other of
the type can be caused to strike at one point on the side of the cylinder A.
Care slides for giving motion to the lever arms B-there is one such slide for

page_text: each arm-A pin B² on a continuation of the arm past the axis B¹ enters a slot C¹
formed in one end of each slide whilst the opposite end of the slide is coupled to
a crank lever D-E E are a series of horizontal parallel lever arms to which the
several crank levers D are coupled by links F. The crank levers used for giving
motion to the uppermost type lever arms cannot conveniently he coupled directly
by links to any of the horizontal levers E and are therefore shewn to be con-
nected to intermediate lever arms G and these are coupled by links to the levers E.
The levers E turn on a fulcrum Et at their rear end and normally are held up
into a horizontal position by springs E2. H H are finger keys by which the front
ends of any one
or other of the horizontal levers E can be depressed. I is a
narrow cylinder lined on the inside with a pad carrying ink-J J are inking
rollers carried by spring wires K from the slides C-L is a fixed ring with
notches cut in for the ends of the type levers B to lie in, one for each lever.
When a finger key is depressed it depresses the front end of one of the hori-
zontal levers E and thereby turns the crank lever D to which this lever is coupled
and so gives an endway movement to one of the slides C. During the first part
of the endway movement of the slide the inking roller J is carried over the face
of the type and passes on to the ink pad-when the inking roller has passed over
the type the end of the slot C¹ in the slide O comes up to the pin B2 on the
continuation of the lever arm B, the further movement of the slide then causes the
lever to turn on its axis and causes the type on the end of the lever arm to strike
against the paper carried by the cylinder A. At the same time the rear end of
the slide is pressed upwards by a spring C2 so that the pin B2 passes into a short
branch slot (which is at right angles to the slot C¹. When the pressure on the
finger key is released the parts return to their former positions, the lever arm B
is made to return during the first part of the backward movement by reason of
the pin B2 then lying in the branch slot ( and when the arm has completed its
movement it is retained by the pin B2 passing into the slot C as the slide continues
its backward movement. To ensure that the pin B2 shall pass from the branch
slot at the proper time the arm B at the end of its return movement is made
to strike against the slide and to move it against the pressure of the spring C².
As the slide completes its return movement the inking roller J is carried off the
inking cylinder I and over the type on the end of the arm B.
The inking cylinder I is as shewn capable of being turned in fixed ring guides M.
Whenever it requires to have fresh ink supplied to its surface it has one or two turns
given to it and then receives ink from an ink roller N which is charged with ink and
is made to bear upon it.
When it is desired that the machine shall be capable of printing in two or more
varieties of type each type arm is as shown made to carry at its end a small roller
with two three or more kinds of type projecting from it.
On each roller is a pinion P which when the type arm is in its normal position
gears with teeth which project inwardly from a ring Q which can be revolved
between guides as shewn-R is a pinion also gearing with this circular toothed rack.
On its spindle it has a small head by which it can be turned to cause the rack to turn
in its guides.
By moving the rack more or less in one direction or the other any one or other of
the sets of type on the type rollers O can be brought into acting position.
As before stated any ordinary means may be used for traversing to and fro the
cylinder A which carries the paper and for giving to it a turning movement after the
completion of each line. In the drawings the mechanism shewn as being used for
this purpose is that used in what is known as the caligraph machine. In it the
depression of any one or other of the horizontal lovers E depressos a bar S carried by
one arm of a crank lever T the other arm of which carries a tooth which as the lever
is rocked passes from one of the toothed racks U to another. The racks are upon
the sliding carriage V which supports the cylinder A the carriage is moved andwise
in one direction by the racks in the well known manner and when a new line is to be
commenced is brought back by the lever arm W turned by the coiled spring Y,

page_text: In the modification of the machine shown at Figures 4 and 5 electro magnets are
used for giving motion to the parts, the type arms B stand normally in a vertical
position instead of in a horizontal position and the cylinder A which carries the paper
is at the bottom instead of near the top of the machine.
Each slide C is shewn to be drawn in one direction by a lever E and in the opposite
direction by a coiled spring E-similarly a pin B2 on the tail end of the type arm B
enters a slot in a link coupled to the lever E and is by this link drawn in one
direction whilst a coiled spring B³ draws it in the opposite direction.
The lever E is coupled by a link to the armature of one of the electro magnets ✗
which is able to draw it in one direction whilst a spring E' draws it in the opposite
direction.
In this way whenever motion is given to one of the levers E by one of the electro
magnets the ink roller J carried by the slide C is moved over and inks the type at the
end of the type arm and is carried on to the inking cylinder I and the type arm is
made to strike its blow. Conversely when the lever E is drawn by the spring E' the
type arm at once returns to its normal position before the inking roller passes off
from the inking cylinder I, just as in the arrangement previously described with
-reference to Figures 1, 2 and 3-H H are the finger keys and Z Z electrical contact
apparatus below each key.
When any one or other of the finger keys is depressed an electrical circuit is
completed through the coils of one of the magnets and the type arm which this magnet
actuates is made to strike its blow.
In Figure 6 D is a crank lever which as in the construction shewn at Figure 1 can
be rocked by the depression of a finger key. B is a type arm with a pin B² on its
tail end entering a slot in a link E coupled to the lever D-C is the slide pressed in
one direction by a spring (and drawn in the opposite direction by a pin on a link F
entering a slot formed in it as shown the link F being itself coupled to the link E.
J is the inking roller and I the inking cylinder.
When a finger key is depressed and the crank lever D draws the link E endwise
the spring is free to press the slide C endwise in a direction to carry the inking-
roller on to the inking cylinder I-the link E then commences to act upon the pin B²
on the tail end of the lever B and causes the type arm to strike its blow. When the
link E is allowed to be drawn back in the opposite direction the slide C at first
remains at rest whilst the type arm is caused to return to its normal position by the
action of a spring B3-Afterwards the pin of the link F comes to the end of the slot
in the slide Ĉ and then draws this slide into the position shewn in the drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A type writer in which the type are carried by type arms ranged radially so that
any of them can be caused to strike on one central spot and in which an inking roller
is caused to be drawn over the face of each type before the arm which carries it is
made to strike its blow.
.
2. A type writer in which type arms are ranged radially in the arc of a circle
in planes at right angles to a paper carrying cylinder so that any one.or other
can strike centrally on to the paper and in which an inking roller is caused to
be drawn over the type just before the arm that carries it commences to strike its
blow.
3. A type writer in which type arms are ranged radially in the arc of a circle
in planes at right angles to a paper carrying cylinder and in which the type arms
receive their motion from links or slides which are ranged outside the arms and
parallel with them or approximately so and are connected to horizontal finger key
levers substantially as described.
4. Mounting the cylindrical inking pad on to which the inking rollers are drawn
back to be supplied with ink in such a manner that it can be revolved and then itself
receive ink from an inking roller.

page_text: 5. Forming the rotating type heads with pinions upon them and making them
to all gear with one circular rack by turning which all the type heads can be turned
simultaneously.
6. The slotted connections between the type arms and slides C to permit of the
completion of the return stroke of the type arm before the return of the inking
roller.
7. The construction of type writers substantially as hereinbefore described with
reference to Figures 1, 2 and 3.
8. The construction of type writers substantially as hereinbefore described with
reference to Figures 45 and 6.
