COMPLETE SPECIFICATION.
Improvements in Type-writing Machines.
I, GEORGE BOARDMAN WEBB, of 327 Broadway, New York, State of New
York, United States of America, Mechanical Engineer, do hereby declare the
nature of my invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
The several objects of this invention, which relates generically to improvements in
type-writing machines, are to produce a machine having much fewer number of parts
than machines of a like nature capable of doing the same kind of work, and by this
reducing the number of parts to lessen the cost of construction thereof, to secure a
machine more quict in its action, and which by reason of its construction is lighter
and consequently more portable than machines of more complicated construction,
one, the manipulation of which is easily learned, which is rapid in use and which
works easily and positively.
In the accompanying drawings is illustrated a machine embodying the principles
of my invention and which is described in the following Specification, and the novel
features thereof embodied in the clauses of the claim.

Figure 18 is an end elevation of the type wheel and the mechanism for inkin
the same shown in its normal unoperated position ;
Figure 19, is a similar view of the same mechanism shown in that position which
it assumes in inking the type wheel; and
Figure 20 is a view of the same part shown in the last named figure with the
addition of the device for applying ink to the inking roller, the parts being shown
in the position they take after the inking roller has inked the type wheel and
passed to the opposite side thereof;
Figure 21 is a modification of the inking mechanism.
As indicated in the views of said drawing, the type wheel, the inking mechanism
and also the mechanism for rotating and sliding the said type wheel for bringing
the various characters to the printing point, are all arranged and carried in the
same rocking frame. By virtue of this arrangement all the parts for operating the
type wheel are compactly located and conveniently placed so that the machine can
be operated with facility and rapidity.
A in said drawings indicates the bed or base which constitutes the frame work of
the machine from which rises standards a between and in which is journalled the
main shaft B of the rocking frame. Projecting from said shaft B are arms b which
extend out toward the paper or printing roll and in the end of which is journalled
the type wheel shaft which also extends down between said arms toward the
shaft B of the rocking frame, substantially as indicated more particularly in Figure 3
of the drawing. The rock shaft B is provided with oppositely projecting arms b',
from which extend projections 3 and 4 between which is journalled a rocking or
oscillating shaft C which carries the oscillating arm c to the end of which is secured
the toothed segment c', and upon the top of said arm is arranged the stop plate c².
This oscillating arm plays directly above the arms of the rocking frame between
which the type wheel shaft d extends, and the toothed segment on said arm meshes
with the pinion d' on said type wheel shaft and by the oscillation of said arm Ca
rotary motion is imparted to said pinion, to the type wheel shaft, and also to the
type wheel D which is secured to the end of said shaft.
Projecting, upwardly from the arms band of the rocking frame are bearing
plates 65 and 66 in which is journalled the finger board shaft e to which is secured the
finger board E which is arranged directly above the stop plate c² on the oscillating
arm c.. By reference to Figures 1, 3, 16 and 17, it will be seen that the finger
board shaft e is arranged in a vertical line directly above the type wheel shaft d,
the purpose of which arrangement will be seen more clearly hereinafter. As thus
arranged the finger or key board is pivoted directly above the type wheel shaft so
that the same is free to vibrate on either side of the pivotal point, the key board
shaft being secured to the centre of the key board. The vibratory movement of
the key board and shaft e is communicated to the oscillating arm c'and the parts
which it operates by means of the fork e' secured to the end of the shaft e, the forked
end of said rod el engaging with a pin or bar c³ projecting from the oscillating
shaft C through a slot in the arm of the rocking frame.
By means of this connecting mechanism when the finger or key board is pressed
on either side of the pivotal point the toothed segment moves in the same direction
as the depressed end of the key board substantially as indicated in Figure 17, and
in consequence the type wheel shaft and type wheel are caused to move in the same
direction.
By reference to Figures 16 and 17, it will be seen that the stop plate c² is carried
with the oscillating arm as it moves beneath the finger or key board.
In order to limit the extent of the vibration or movement of the key board, and
also to lock or stop the oscillating arm at any desired point, I have provided a
series of pins e³ working in and projecting above the finger board, which when
depressed project from the under side of said board, and engage with the arms c* on
the stop plate. These arms on the stop plate are so arranged that when its

page_text: corresponding pin in the key board engages with any one of the arms the movement
of the key board and of the oscillating arm is limited to such an extent that a
certain character on the type wheel is rotated or presented to the printing point
according to the letter indicated on the key board or contiguous to the pin which is
depressed. Thus cach character on the type wheel has its corresponding pin on
the key board which is properly indicated so that the operator understands which
pin to depress to bring any character to the printing point. Spiral springs e³
co-operate with the pins to restore the same to their normal position when released
from the pressure of the finger. As indicated in Figures 1 and 2, each pin is
provided with a head or finger piece upon which is placed a character which is
controlled by that particular pin.
Springs are secured to opposite sides of the arm b³, as indicated in Figures 1
and 2, and engage with opposite sides of a pin e on the oscillating arm c projecting
up between the ends of said spring. The functions of these springs are to return the
oscillating arm to its normal unoperated position directly above the type wheel
shaft. A finger 6° projects from the said arm 73 down between the said springs and
prevents either of said springs from following the other when pressed to one side
by the operation of the oscillating arm. By this arrangement the unoperated
spring is prevented from exerting or opposing any resistance to the operating spring
in returning the oscillating arm to its normal position.
In order to prevent the type wheel from turning after, by the movement of the
key board, any character is brought around to the printing point, I have provided
the device shown more particularly in Figures 16 and 17, which consists of slotted
lugs 10 and 11, projecting downwardly from the arms of the rocking frame and
pivoted in the slotted lug 10, and extending through and beyond the slot in the
lug is an arm or lever 612 directly beneath the pinion on the type wheel
shaft. In Figure 16 is indicated the normal disengaged position of the locking
lever, while in Figure 17 is shown the locked position of the same in which, by the
downward movement of the rocking frame, the end of said lever engages with
the spring actuated pin a' arranged in a post a² projecting upwardly from the bed
of the machine, and by said engagement the point 613 is caused to engage with the
teeth of the pinion and thereby prevent any further movement thereof, substantially
as indicated in said Figure 17. When the rocking frame is released and permitted
to rise, the lever 12 is lifted clear from the pin a' and the spring 64 restores said
lever to its normal unoperated position as indicated in Figure 16.
As hereinbefore mentioned the mechanism, for sliding the type wheel so as to
bring the characters in any one parallel row of type which surround the periphery
of the wheel into that position in which, by the operation of the rotating mechanism,
any one of the characters in any one of said rows is brought to the printing
position, is arranged in the same rocking frame as the rotating mechanism.
As indicated in the drawing, the mechanism for producing the sliding movement
of the type wheel consists of a series of keys, one for each row of type on the
wheel, each of said keys being independently connected with the type wheel shaft,
and having such a degree of movement as will bring the row of type corresponding
to each key to the printing point.
The particular mechanism shown in the drawing consists of two standards f
and projecting from the main shaft B of the rocking frame, and journalled in
said standards is a shaft g to one end of which is secured a crank arm g' from which
projects a pin g², and connecting said pin with the end of the type wheel shaft is
a jointed link g³ in which is formed a ball and socket joint g, substantially as
indicated in Figures 7 and 8. The object in thus using a ball and socket joint in
the link connecting the type wheel shaft and crank is to permit said shaft to rotate
freely and at the same time to provide a suitable connection with the sliding
mechanism. Each of the keys h turns on the shaft by means of a collar
through which said shaft passes and in each of said collars is a recess ²
through which project pins 7' on the shaft g substantially as indicated in Figures. 8
and 10.

page_text: When either of said keys is turned the side of the recess in the collars engages
the pin projecting therethrough on the shaft g and causes said shaft to turn, which
in turn produces the sliding movement of the type wheel shaft and type wheel
through the connecting mechanism hereinbefore described, the degree or extent
of movement of each of said keys is limited or defined by the stops f indicated in
Figures 7, etc.
Springs cause the return of the shaft g and the sliding type wheel to its
normal position and springs h³, encircling the curved arm that projects from the
under side of each key and work through a plate f³ on the standard, cause the
return of the keys to their normal unoperated position indicated in Figure 7.
By this arrangement of the sliding mechanism, a type wheel of smaller diameter
may be used, but of increased length, and thus avoid the necessity of increasing
the extent of the vibration of the key board, and by arranging the keys which
control the sliding mechanism in the same rocking frame, immediately in front of and
in the same plane with the key board, and adjacent thereto, they are conveniently
placed for rapid manipulation.
The mechanism for inking the type wheel is shown more especially in detail in
Figures 18, 19, and 20, and consists essentially of an inking roller held normally
out of the path of movement of the type wheel as it oscillates up and down, but
which is caused to vibrate or move in a line crossing the path or line of movement
of said type wheel and to brush or rub the face thereof at the printing point, and
then moves out of the way of said type wheel which is free to move downward to
the printing roll or bed. As the type wheel returns to its normal position the
inking roll returns to the opposite side of said type wheel, which is its normal
unoperated position. The mechanism shown in the drawing for accomplishing this
end consists of an arm i which carries the inking roll I, said arm being pivoted at i¹
to the arms that carry the type wheel, and is also provided with an arm or
finger. The inking roll is secured in the arm i by means of the bar or rod 3.
When the type wheel is elevated in its normal position, the relative position of
the type wheel and roller is as indicated in Figure 18, the type wheel, however, being
elevated at a greater distance above the stop or post a than is shown in said
Figure 18, in which the type wheel is shown as having been lowered until the
finger engages with the top of the stop, but before it has caused any movement
of the inking mechanism. As the downward movement of the type wheel continues
the engagement of the finger 2 and stop a³ causes the inking roller to move to the
position shown in Figure 19, in which it presses or rubs against the face of the
type wheel, and as the type wheel still further continues its downward movement
the engaging finger and stop has caused the inking roll to move to the position
indicated in Figure 20 where it engages with the ink supplying roll or pad *, which
is secured to the arms b of the rocking frame by the rod. This latter position
of the inking roll is maintained until the type wheel has left its imprint upon the
roll, while the same is rising to its normal position, and until the finger and stop
are released from their engagement, at which time the inking roll returns to its
normal unoperated position which is indicated in Figure 18.
By reference to Figures 18 to 20 inclusive, it will be seen that the arm i extends
around and beneath the type wheel from the side opposite to that on which the
inking roll is placed when in its normal unoperated position, or in other words the
said inking roll is attached to a pivoted arm which extends from that side of
the type wheel toward which said inking roll is designed to move as it inks the face
of said type wheel. The relative movements of the inking roll and type wheel
are designed to be so timed that the inking of the roll takes place after the type
wheel has been rotated so as to bring the desired character to the printing point,
and while said type wheel is being lowered towards the paper carrying roll.
of
The mechanism for receiving the paper, and for moving the same beneath the
type wheel consists of the roll J journaled in standards; rising from the bed
the carriage which is provided with one or more friction rolls 2 journaled in a
suitable yoke at the rear of the bed of the carriage, said roller moving on a

page_text: planed surface at on the bed of the machine, the front of the carriage being provided
with a V-shaped recess at 4, which receives and moves on a projection or way a³,
formed on the top of the flange a, which projects upwardly from and extends the
length of the machine. As thus constructed it will be apparent that the entire
carriage can be lifted directly from the bed of the machine, and when. in position
the yoke prevents the same from becoming accidentally separated from the bed of
the machine.
As indicated from Figures 1 to 5 inclusive, the standards are provided with
extended arms so constructed as to form bearings to receive the journals of the
shaft k to which is secured and from which springs the arms k¹ of the paper holding
frame, which are connected by a bar k³ at their ends substantially as indicated in
Figure 1.
The engagement of the paper holding frame with the paper supporting roll is
maintained by means of the spiral springs k³, which encircle the shaft k, one end of
said spiral springs 4, engaging with the underside of the curved paper shield or
protector as indicated in Figures 4 and 5, a spring surrounding the rod k, as
shown in Figure 6, being employed to hold the frame in place. In each of the
arms k¹ of the paper holding frame are curved slots in which work the journals
of a roller, which are employed to press the paper upon the printing roll or
platen, the pressure of said roll being caused by the other end of the spiral
spring, said ends 7 engaging with the journals of the roll k, substantially as
indicated in Figures 4 and 5. As thus constructed it will be seen that the main
portion of the paper holding frame may be lifted clear of the paper roll or platen
a short distance, as indicated in Figure 4, without removing the roll 4 from its
contact with the printing bed. By lifting the paper frame still further as indicated
in Figure 5, the roller 6 is also carried away from the printing roll substantially
as indicated in Figure 5.
As indicated in Figure 1, the paper roll is provided with a milled finger
piece whereby the same may be turned, and on said finger piece are ratchets,
with which a detent or pawl engages to hold said paper roll in any desired
position.
In Figures 6, 11, 12, and 13 is illustrated the mechanism employed to propel the
carriage beneath the type wheel after the printing of each character or in spacing.
Said mechanism consists essentially of a pivoted lever to which is pivotally secured
a pawl, a stop for controlling the movement of said pawl, and a spring or other
suitable means engaging with said pawl or the end of the pivoted lever to depress
the same.
As indicated in the detail views, the pivoted arm or lever is secured to the
front of the base or bed of the carriage at land to said lever, preferably near
the end thereof, is pivoted a pawl 12, which engages with the teeth of the rack 13,
arranged below said pawl and attached to the flange a on the bed of the
machine. The spring suitably placed, engages with the end of the pivoted
lever and acts to press the same down toward the rack, and to hold the pawl
in engagement with the teeth thereof. On said lever is a stop with which
the pawl engages when lifted clear of the rack, substantially as indicated in
Figure 11, and on the end of said lever is provided a projection 16, with which the
plate m on the mechanism that controls the operation of the carriage propelling
device, engages in raising the end of the pivoted lever whereby the pawl is lifted
clear of the rack.
By reference to the detail views, Figure 11, etc., it will be seen that the
pawl is not pivoted to the lever / directly above the stop 5, but that the pivotal
point of said pawl is back of said stop, or toward the point of attachment, 1 of the
fever to the carriage.
The operation of the device is as follows:-
The position of the parts when unoperated and at rest is shown in Figure 12,
in which it will be noticed that the gravity pawl engages with a tooth on the rack
numbered 1. and that there is a snace intervening between the nawi and the ston 7º

page_text: when the parts are in this position. When the pivoted lever l'is raised so that the
pawl clears the rack, the said pawl drops automatically until it strikes the stop 1³,
and when in this position is directly above the next tooth on the rack, numbered 2,
so that when the lever is allowed to fall a sufficient distance the end of said pawl
engages with said tooth, substantially as indicated in Figure 13.
Up to this point in the operation of the device there has been no movement of
the carriage, but as the pivoted lever is permitted to fall still further, the downward
pressure of the spring 1, upon the end of said lever causes the carriage to move
forward until the pawl assumes the position shown in Figure 12, which is its posi
tion of rest. By this construction, a very simple, and yet positively acting device
is provided for propelling the carriage, and which, because of its simplicity, can be
cheaply made and is not liable to become disarranged.
The mechanism for operating the carriage propelling device, consists of a rocking
shaft m' journalled in the bed of the machine from which project arms m² to the
ends of which is secured the plate m already referred to that engages with the pro-
jection on the end of the pivoted lever l, as hereinbefore described. Projecting
in an opposite direction from said rocking shaft m² are arms m³ provided on the
end thereof with finger plates m', substantially as indicated in Figure 1.
Any downward pressure applied upon the plates m³, elevates the plate mon
the opposite side of the rocking shaft, which in turn lifts the pivoted lever of the
carriage propelling device as already described. This mechanism constitutes or
has the same function as what is known as the "spacer" in other forms of type
writing machines. In order that the carriage may be automatically propelled
after each character has been printed, and that the same operation which prints
the character shall at the same time cause the carriage propelling device to
move the same, I have provided a pin m³, projecting from one of the arms m³, and
engaging with said pin, which is dotted beneath the key or finger board in Figure 1,
is an arm me secured to and projecting from the main shaft B of the rocking frame.
Hence from this construction it will be apparent that any downward movement_of
the rocking frame actuates the spacing mechanism simultaneously therewith. To
prevent an excessive movement of the spacing mechanism, the plate m is caused to
engage with the upright a' at the point m', substantially as indicated in Figure 3.
A spiral spring, 610, suitably secured around the main shaft B, is employed to
restore the rocking frame to its normal unoperated position, as shown in
Figure 2.
The stop also acts as a locking tooth to prevent any movement of the
carriage when the pivoted lever falls and the pawl engages the rack. Instead
of using this same stop as a locking tooth, an independent tooth can be used
for that purpose.
From the above description of my improved type writing machine, it will be
seen that it consists essentially of a moving finger board which actuates the type
wheel by suitable devices for transmitting said motion, and provided with stop
mechanism whereby the degree or extent of movement of the finger board is so
regulated and limited that any particular character on the type wheel can be
brought to the printing point by means of the independently operating stops. In
this my machine differs from other machines.
In Figure 1 is indicated the arrangement of the characters on the indicating
or finger board.
