Complete Specification Left, 13th Aug., 1897-Accepted, 18th Sept., 1897
I, ALFRED HENRY HUTHI, of Bolney House, Ennismore Gardens, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements particularly applicable to the machine
described in the Specification of my Patent No. 17771 of 1892 but they can also be
used with other machines.
The paper carriage has fixed to it a rack gearing with a pinion on a ratchet wheel.
This ratchet wheel and pinion are pivotted on a stud fixed to the frame of the
machine and the ratchet wheel which is hollow contains a helical spring having one
end fixed to the stud and the other to the wheel so that the latter tends to turn.
Three retaining pawls gear with the ratchet wheel two being fixed to two levers
whilst the third is pivotted to a third lever. The latter lever has a stud acting on
the tail end of the first pawl and carries a pin or roller working in a cam slot in the
second lever which is connected by a rod to and is moved up and down by a pivotted
rod or frame actuated in the usual way by the finger keys. As in the former machine
there may be several of these pivotted frames in which case there are a corresponding
number of the second and third levers.
The action of the apparatus is as follows:-On a key being put down the pivotted
frame is raised turning the second lever about its pivot which in its turn draws the
third lever by the pin to one side. The result of this is that the second and third
pawls are almost simultaneously put into gear with the ratchet wheel. The stud
also coming against a projection on the tail end of the first lever lifts the first pawl
out of gear. When the key is released and the pivotted frame tegins to fall the
first effect is to draw the second pawl out of gear and the ratchet wheel thereupon
begins to turn carrying with it the third pawl which is turned about its pivot against
the action of a spring. After a time however the third pawl comes against an arm
on the third lever and is arrested thus stopping the wheel. The number of teeth
through which the wheel turns is determined by the space between the arms between
which the third pawl turns and where several pivotted frames are employed as in
the former machine the corresponding third levers have different spaces between the
arms on them. The third pawl has a plate projecting downwards from it and when
the first pawl is out of gear and the third pawl is being pulled downwards by the
wheel as above described the plate comes between the wheel and a pin on the first
lever so preventing the first pawl from prematurely arresting the wheel. The spring
of the first lever also causes the pin to press on the plate and so hold the third pawl
in gear after the second or cain lever (by reason of the descent of the pivotted frame)
has ceased to act on the third lever the cam groove being sufficiently wide to prevent
the return of the second lever from forcing the third lever back. The plate has
however a notch in it and when the pin reaches this it passes through and the first
pawl goes into gear and the third pawl comes out of gear. However many pivotted
frames are employed there is preferably only one first lever but this is provided with
as many pins as there are frames.

page_text: . The method of feeding the paper is as follows:-
At the end of the paper roll is a ratchet wheel operated by a pawl pivotted to a
lever which itself is pivotted to the paper carriage. Another lever is also pivotted at
the same place and has at its other end a roller. An inclined plate is provided
secured by a nut in any desired position in a slot in the frame of the machine.
When the carriage is moving from left to right the roller rides up this incline and its
lever simply turns up about its pivot and does not move the lever carrying the pawl.
When however the carriage is being drawn or pushed back from right to left by one
of its handles the roller passes beneath the incline and is forced down by it and the
two levers owing to the forms of their ends move together and the paper roll is
turned. In some cases however it is desirable to move the carriage from right to
left without turning the paper roll. To enable this to be done the handle is not
rigidly fixed to the carriage but is mounted on a longitudinal spindle working in
bearings in it. Fixed to the spindle is an arm and when the handle is turned to the
rear this arm comes beneath and lifts the lever carrying the roller so that if the
carriage be moved from right to left with the handle in this position the roller passes
above the incline and the paper roll is not turned-a spring is provided which
normally tends to keep the handle vertical.
When using very fluid ink with the semi-circular inking pad described in my
former specification I find that the ink tends to run down to the middle. According
to this invention I prevent this by dividing the pad into a number of pieces separated
by partitions.
Dated this 13th day of November 1896.
İ, ALFRED HENRY HUTH, of Bolney House, Ennismore Gardens, in the County of
Middlesex, 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:-
This invention relates to improvements particularly applicable to the machine
described in the Specification of my Patent No. 17771 of 1892 but they can also be
used with other machines.
Figure 1 is a back elevation of the improved machine. Figure 2 is a local section
on the line 2-2 Figure 1. Figure 3 is an edge view (looking from the left of
Figure 1) of the lever g. Figure 4 is a plan of the lever h and Figure 5 is a section
on the line 5-5 Figure 4. Figure 6 is a left hand elevation of the lever d. Figure 7 is
an elevation of the inking pad.
a is the paper carriage to which is fixed the rack b gearing with a pinion on the
front of the ratchet wheel c. The ratchet wheel and pinion are pivotted on a stud c¹
fixed to the frame of the machine and the ratchet wheel which is hollow contains a
helical spring having one end fixed to the stud and the other to the wheel so that the
latter tends to turn in the direction of the arrow. d is a retaining pawl on a lever d
pivotted at d² and held in gear with the wheel c by the spring d. e is a lever having
fixed to it a retaining pawl e¹ and being pivotted at e. It has one end connected by
the rod e³ to the pivotted frame or stepping lever f which is caused to rise in the
usual way by the depression of the keys of the machine. The other end of the
lever e has a cam slot in it to receive a pin or roller gl on the lever g which is pivotted
at g². The lever g has fixed to it a projecting stud g³ and pivotted to it at h¹ is a

The lever is normally held up by a
spring against the underside of an arm g' on the lever g.
h³
As in the foriner machine several levers f may be employed in which case there are
a corresponding number of levers e and y."
The action of the apparatus is as follows:-
On a key being put down the lever f is raised turning the levere about its pivot
which in its turn draws the lever g by the pin gl from right to left of Figure 1. The
result of this is that the pawls e' anil & are almost simultaneously put into gear with
the ratchet wheel c. The stud g³ also coming against a projection d' on the tail end
of the lever d lifts the pawl d¹ out of gear. When the key is released and the
lever begins to fall the first effect is to draw the pawl e¹ out of gear and the wheel c
thereupon begins to turn carrying with it the pawl h' on the lever & which is turned
about its pivot against the action of the spring 4. After a time however the
lever h comes against the arm g' on the lever and is arrested thus stopping the
wheel c. The number of teeth through which the wheel a turns is determined by
the space between the arms g' and g' and where several levers are employed as in
the former machine the corresponding levers g have different spaces between their
arms g and g. The lever à las a plate projecting downwards from it and when
the pawl d is out of gear and the lever h is being pulled downwards by the wheel c
as above described the plate h' comes between the wheel c and a pin d on the lever d
so preventing the pawl d¹ from prematurely arresting the wheel c. The spring d³
also causes the pin d' to press on the plate hand so hold the pawl h² in gear after
the cam lever e (by reason of the descent of the lever f) has ceased to act on the
lever g the cam groove being sufficiently wide to prevent the return of the lever e
from forcing the lever y back from left to right. The plate h has however a notch h
(see Figure 5) in it and when the pin d' reaches this it passes through and the
pawl d goes into gear and the pawl h2 comes out of gear. However many levers f
(and h) are employed there is preferably only one lever d but this is provided with as
many pins d' as there are levers h, thus Figure 6 shows four.
The method of feeding the paper is as follows:-
At the end of the paper roll al is a ratchet wheel a² operated by a pawl pivotted
at to the lever ; which is pivotted at j. k is another lever also pivotted at and
having at its other end a roller k. is an inclined plate secured by a nut in any
desired position in a slot m in the frame of the machine. When the carriage is
moving from left to right the roller rides up this incline and the lever le simply
turns up about its pivot and does not move the lever j and pawl j'. When however
the carriage is being drawn or pushed back from right to left by one of its
handles a a' the roller passes beneath the incline and is forced down by it and
the levers and & owing to the forms of their ends (clearly shown in Figure 3)
move together and the paper roll is turned. In some cases however it is desirable
to move the carriage a from right to left without turning the paper roll. To enable
this to be done the handle a is not rigidly fixed to the carriage but is mounted
a longitudinal spindle a working in bearings in it." Fixed to the
spindle a is an arm a and when the handle is turned to the rear this
arm comes beneath and lifts the lever k so that if the carriage be moved
from right to left with the handle in this position the roller k passes above the
incline and the paper roll is not turned. is a spring which normally tends to
keep the handle a³ vertical.
When using very fluid ink with the semi-circular inking pad described in my former
specification I find that the ink tends to run down to the middle. According to this
invention I prevent this by dividing the pad into a number of pieces a separated by
partitions o as shown in Figure 7.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination of a paper carriage, a ratchet wheel operatively connected

page_text: with it which revolves when the carriage advances, a retaining pawl normally
engaging with the ratchet wheel, a retaining pawl and an operating pawl adapted to
engage but nortnally out of gear with the ratchet wheel the operating pawl having a
certain freedom of movement and connections between these pawls and the finger
keys whereby the depression of a key puts the second and third pawls into gear and
the first pawl out of gear and the release of the key successively puts the second
pawl out of gear, the first pawl into gear and the third pawl out of gear.
2. The combination of a paper carriage, a ratchet wheel operatively connected
with it which revolves when the carriage advances a retaining pawl normally engaging
with the ratchet wheel, a retaining pawl and an operating pawl adapted to engage

freedom of movement a projection carried by the first retaining pawl a notched plate
carried by the operating pawl and adapted to come between the ratchet wheel and
the projection when the first retaining pawl is out of gear and the operating pawl is
in gear and connections between these pawls and the finger keys whereby the
depression of a key puts the second and third pawls into gear and the first pawl out
of gear and the release of the key successively puts the second pawl out of gear, the
first pawl into gear and the third pawl out of gear.
3. The combination of a paper carriage, a ratchet wheel operatively connected
with it which revolves when the carriage advances a retaining pawl normally engaging
with the ratchet wheel, a lever having a cam slot in it, a retaining pawl fixed to the
cam lever, connections between the finger keys and the cam lever whereby the cam
lever is turned on the depression of a key a second lever a pin or roller on the
second lever engaging in the slot in the cam lever, a projection on the second lever
adapted to press on the tail end of the first retaining pawl and lift it out of gear, an
operating pawl pivotted to the second lever, stops limiting the movement of the
operating pawl a projection on the first retaining pawl and a notched plate carried by
the operating pawl and adapted to come between the ratchet wheel and the projection
when the first retaining pawl is out of gear and the operating pawl in gear.
4. The mechanism for traversing the paper carriage substantially as described and
shown in the drawings.
5. The combination of a paper carriage, a paper roller on the carriage, a ratchet
wheel at one end of the roller, a pawl engaging with the ratchet wheel, a lever
operating the pawl, a second lever pivotted to the first lever free to turn in one
direction but coming against and operating the first lever when turned in the other
direction and an incline adapted to act on the tail end of the second lever.
