Improvements in Type-writing Machines.
I, CHARLES THOMAS MOORE, of 1335 15th Street, Washington, in the District of
Columbia, United States of America, Attorney at Law, do hereby declare the nature
of my invention for IMPROVEMENTS IN TYPE-WRITING MACHINES, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:―
My invention has for its object to provide a type-writer in which the types or
characters employed are of variable widths like ordinary printer's type; in which the
spacing mechanism is constructed to feed the record each time a key is struck, a
distance corresponding to the width of the character printed by the striking of such
key; and in which the impressions are made directly from the types or characters
employed and by the aid of ordinary printer's ink. In a word, my aim is to provide
a machine which will turn out work exhibiting that clearness and uniformity of
impression and accuracy and regularity of spacing found at present only in printer's
press work.
In ordinary type-writing machines, each character is printed upon the striking
of the key employed for designating that character and the act of designation and
the act of printing are so closely identified and occur so nearly together as to amount
to but one act, the result being that when a wrong key is struck the character
corresponding to that key is printed and recorded before the opportunity is given to
correct the error, and when a correction is afterwards attempted to be made the time
required to erase the wrongly recorded character, adjust back the record and print
over the erasure the proper character, militates against the general efficiency of the
machine.
An apprehension of this serious defect has led me to introduce an entirely new
method or principle of operation into machines of this class, to wit, the principle of
designating or setting for operation a given character upon the striking of a given
key and subsequently printing the character so designated upon the striking of the
same or another key for the designation of the same or a different character.
By thus having the printing of a character consequent not upon the designation
of itself, but upon the designation of the next succeeding letter, an opportunity,
afforded to correct an error due to striking a wrong key before said error recorded
on the paper and the speed and general efficiency of the machine is thereby promoted.
This new principle which I have invented constitutes a new process or method of
operation consisting in designating characters to be printed by one operation and
imprinting them by another or second operation, and consisting in the designation
of a character to be printed, and a letter space feed at one operation and imprinting
said designated character and executing the designated feed by a subsequent operation,
to the end that a character erroneously designated may be removed and the intended
character substituted therefor.
There are of course many ways in which this new principle of operation may be
embodied, all falling within the scope of my invention, but I propose herein to
describe only one embodiment of it, believing that more will not be required to a
full and clear understanding of it.

Referring now particularly to figures 1, 2, 3, 4 and 6 and 18, numbers 3 and 4
represent two type-wheels secured one above the other to a common hub 4ª mounted
on a shaft 5, as seen in figure 18. A pin 5b passes through hub 4ª through a
longitudinal slot 5° in said shaft 5 and through a short shaft 5" and operates to cause
the type-wheels to rotate when the shaft 5 is rotated and yet permitting the said
shaft 5 and the type-wheels to be raised or lowered independently so as to bring one
or the other of the type-wheels opposite to and in position to co-operate with the
impression surface 57ª. As a means for thus shifting the position of the type-wheels
with respect to the impression surface, I connect to the upper end of the shaft 5 a
rod 173, which extends horizontally a short distance and then passes down vertically
to near the bottom of the machine, where it is articulated to a lever 174 pivoted at 175
and arranged to be operated by a key 176, which I term the " upper case key." By
pressing upon this key 176, the type wheels through the connections named, are raised
so as to bring the lower wheel into position for printing, said lower wheel bearing
upon its periphery the upper case characters. The lower case characters are arranged
upon the periphery of the upper wheel. Each time the type-wheels are raised the
upper notched arm of a bell-crank lever 178 is forced by a spring 180 (figures 4 and 6)
under a pin 177 on the rod 173 and holds the latter and the connected type-wheels
in elevated position. This movement of the bell-crank lever causes its longer arm to
be raised and a latch 181 mounted thereon and kept closed by a spring 182, to be
swung into the path of an arm 183 that is mounted on a shaft 65, which extends
transversely of the machine, and which is rocked or oscillated each time one of the
keys of the key board is depressed through the medium of a transverse bar 64 that
extends beneath the keys and is connected to the said shaft 65 by arms 64ª, as seen
in figures 2, 3 and 6.
When a key is depressed, the arm 183 strikes the latch 181, trips the latter and
passes above it, but when said key is released and the arm 183 returns to first position
said arm in its descent strikes the latch which is now immovable and tilts the bell-crank
lever sufficiently to cause the withdrawal of its notched arm from beneath the pin on
the rod 173, thus permitting the said rod and the type-wheels connected to it to drop
to normal position.
Secured to the type-wheel shaft 5 is a pinion 6 with which meshes a gear wheel 134
mounted loosely on a shaft 134" and connected to a barrel or drum 127 on said shaft
by a ratchet wheel 134° on said drum and a spring pawl 134ª on said gear 134, as
shown in figure 6.
To this barrel is attached one end of a cord 128, the other end of said cord being
attached to a fuzee 129 that is adapted to be rotated by a spring arranged within it in
the usual manner. This spring-impelled fuzee tends to draw the cord 128 from the
barrel 127 and thereby rotate said barrel, and through the described gearing rotate
the type-wheel shaft forward in the direction indicated by arrow, figures 2, 3 and 18.
As a means for rewinding the cord 125 upon the barrel, I attach to the barrel another
cord 126 which passes thence over a pulley 124 mounted in a bracket or hanger 125,
thence around a pulley 123 mounted on a swinging hand lever 118, and thence to a

page_text: stationary part of the frame, as at 122. Upon the lever 118 being drawn forward, the
said cord 126 will be withdrawn from the barrel 127 and in so doing will rotate the
latter and re-wind thereon from the fuzee, the cord 128. By this provision, the fuzee
is kept at all times wound up in operative condition, its power being renewed each
time the hand lever is drawn forward.
Secured to the type-wheel shaft 5, near its lower end, is an arm 17 (6gures 3 and 18)
which is provided with a projection 17" and is connected through a spring 17 to a
swinging arm 16, mounted loosely upon the hub of the arm 17, as shown.
This arm 17 also carries a swinging friction pawl 18, which is kept pressed against
the inner circumference of the dial 21, by a spring 19, and prevents any return
movement or back lash of the arms 17 and 16, when said arms are arrested after an
advance movement.
The outer end of this arm 16 is adapted to engage with the side of one of a
series of stop pins 20 arranged in a dial 21, concentrically to the type-wheel shaft,
as shown in figure 18. These stop pins 20 are as many in number as the keys of
a key board and each is capable of a vertical movement in the dial, limited as to
extent by the length of a slot 22, formed in it and into which projects a ring 23.
Beneath the dial are arranged a series of fingers or levers 27 corresponding in
number to the number of pins employed, the ends of said levers or fingers occupying
a position immediately beneath the pins. These levers in turn are adapted to be
operated upon by the keys of the key board.
Whenever a key is struck, the lever of finger 27 corresponding to it is vibrated and
throws up the corresponding pin in the dial into the path of the swinging arm 16, as
shown in figure 18, so as to arrest the latter when released as will hereinafter more
fully appear.
Surrounding the type-wheel shaft 5 is a sleeve 12, which carries at its lower end
an arm 14 whose shorter portion is perforated and is adapted to slide up and down
upon a pin 15 on the shorter portion of the arm 16, but whose larger portion extends
out over the dial and terminates just above the stop pins.
Upon the upper end of the sleeve 12, rests a yoke 7, which is provided at its
upper portion with projections 9, that are adapted, when the yoke is lowered, to
engage with the teeth of a locking wheel 8 secured rigidly to the type-wheel shaft.
This yoke 7 has no rotative movement but it is guided in its vertical movements by
means of pins 11 depending from a bracket 10 and passing through guide perforations,
as shown. A spring 25, arranged within the sleeve 12, operates to keep said sleeve
in an elevated position and consequently the arm 14 out of contact with the stop pins
and the projections on the yoke 7 out of engagement with the locking-wheel 8.
From the foregoing description, it is believed the following statement of the operation
of this part of the mechanism will be understood.
In the first place, it should be borne in mind that one of the stop pins in the dial is
always left in a raised position, and that against this raised pin the swinging arm 16 is
kept pressed by the operation of the type-wheel shaft-rotating mechanism. When,
therefore, a key is depressed for the designation of a given letter, a stop pin corre-
sponding to the key struck is thrown up from the dial and simultaneously therewith a
lever 62 (figure 6) actuated indirectly by the keys in a manner to be hereinafter
described, is swung downward and bearing on yoke 7 causes the projections 9 on said
yoke to engage with the locking wheel 8 on the type-wheel shaft so as to hold said
shaft from rotating and at the same time causes arm 14 to depress the previously
raised or set up pin, thereby releasing the arm 16 from said pin and permitting the
spring 17 mounted on the arm 17 to force forward the arm 16 until it comes in
contact with the projection 17ª on the arm 17. While the type-wheel shaft thus
remains locked, and while the depression of the previously set-up pin and the advance
of the arm 16 is thus taking place, the impression surface advances toward the
type-wheel to make an impression, in manner to be hereinafter described.
After the impression has been made, and while the depressed key is still con-
tinuing its downward movement the yoke 7 is released, and rising under the
influence of the spring 25 becomes disengaged from the locking-wheel 8, thereby

page_text: -
releasing the type-wheel shaft and permitting it to rotate till arrested by the contact
of the lever 16 with the pin just raised, such contact and arrest taking place at the
time the character on the type-wheel corresponding to the key struck reaches the
printing point.
Upon the striking of the next key, the stop pin corresponding to that key is set up
and the operations just described repeated, including the printing of the character
designated by the previous key, as described. I would here state, in passing, that
when the arm 16 after having been released from contact with one stop pin is by the
rotation of the type-wheel shaft and connections brought around in contact with the
next stop pin, the force of the blow in making such contact is very sensibly diminished
by the yielding of the spring 17° and all liability of injury to or breakage of parts is
thereby obviated.
I have already stated that after the stop arm 16 has been released from engagement
with one of the stop pins, the spring 17 bearing against it causes it to make a
slight advance, in other words, forces it up against the projection 17ª on the arm 17.
This advance movement of the arm 16 is necessary in order that it shall clear and
pass fully beyond the depressed pin so that if the depressed pin should happen to be
the next one to be struck up, the arm 16 of the type-wheel shaft to which it is con-
nected would be required to make the latter a complete, and the former nearly a
complete circuit and in so doing insure the proper re-inking of the type-wheel, as will
be explained further on.
The finger levers 27 which are operated on by the keys to raise or strike up the stop
pins of the dial are made springy or elastic so that when the same pin is employed
twice in succession, in which case the action of the arm 14 on the one hand to depress,
and of the finger lever on the other hand to raise said pin are concurrent, the finger
or lever will yield when opposed by the action of the arin 14 and then re-assert itself
and press the pin upward into position.
The paper carriage 144 is provided with rollers 145 which co-operate with the
ways 145 on the frame and serve to guide the carriage in its movements back and
forth across the machine in front of the type-wheels.
This carriage carries a roller 149 upon which the paper employed is wound and
another roller 146 which operates in connection with the two presser rollers 147 to
feed the paper as each line is printed. To one end of the carriage is connected a
strap 144 that leads to an ordinary spring drum 144', figs. 1 and 4, the spring in
the drum operating at all times to keep the strap under tension as will be readily
understood.
To a pin or stud 141" on the paper carriage is connected one member of a toggle 141,
the other member of said toggle being connected to a lever 151 hung upon the axis
or bearing of the paper feed roll 146 and carrying a spring-pressed friction pawl which
is adapted to co-operate with a friction rim or flange 154 on the end of the feed roller
(figure 29).
The members of the toggle 141 are connected together by means of a link or
block 141 through which passes a small screw-threaded eye-bolt 142, the position of
which is regulated by means of adjusting nuts 143.
To the eye of bolt 142 is attached a cord 136 which passes thence over a pulley 139,
thence around a pulley 138 supported in the bracket 125 and thence around a third
pulley 137 mounted on and carried by the hand lever 118 and thence to a stud 135,
to which it is connected.
Each time the hand lever is drawn forward, two results are accomplished, to wit,
first, the toggle arms 141 are straightened out by a pull upon the cord 136 thereby
causing the lever 151 to be swung upon its axis and, through the action of the friction
pawl 152 upon the friction rim 154, cause the feed roll 146 to be rotated a distance
sufficient to feed or advance the paper to receive the impression for the next line,
and secondly, the paper carriage is drawn back bodily to starting point, thereby
winding up again, through strap 144, the spring within the drum 144.
The toggle arms and the lever 151 operated by them are retracted by means of a
spring 143 as shown in figures 1 and 29.

page_text: The mechanism by which the impressions are made by the type-wheels upon the
paper is as follows.
Upon the frame of the machine (figs. 1, 6, 22, 23,) is mounted a guide 58 in which
is arranged a reciprocating slide or plunger 57 having a head 57 which is adapted
to co-operate with whatever character happens to be at the printing point and in the
same plane with it, to make an impression of such character upon the interposed paper.
This slide or plunger 57 has connected to it one member 55 of a toggle, the other
member 56 of the same being connected to a block 59 rendered adjustable by a set
screw 60 (fig. 22). Connected to the toggle 55-56, is the upper end of a rod 54,
the lower end of said rod being jointed to a pin 53 on a slide 43 which is adapted to
work back and forth in a guide 46 on a dísk 42 mounted on a shaft 40 (figs. 2, and
24 to 28).
This shaft 40 has its bearings in a bracket 40" and carries upon its other end a
disk 39 (fig. 6) to the periphery of which is secured the flattened or strap-like end 38
of a rod 37 that is connected to an arm 36 secured to the rock shaft 65 that is
operated from the finger keys through the medium of the cross-bar 64 and arms 64ª,
as before described.
When the shaft 65 is rocked by the operation of a finger key, the rod 37 is
pulled and its flattened or strap-like end operating upon the drum 39 rocks the
shaft 40 against the tension of spring 41 and rocks the disk 42.
Now the slide 43 which is arranged on the disk 42 is provided with a pin 44 which
projects through slot 45 in disk 42 and extends beyond the opposite side of said disk.
Normally the position of the slide with respect to the disk is as represented in
figure 24 and its pin 44 is located between the hub 47 of the disk and a stationary
cam 48, and a spring-pressed arm 49 (fig. 25) while the pin 53 acting through the
rod 54 and toggle 55-56 keeps the impression plunger retracted, but on the disk 12
being turned by the depression of a finger key through the described intervening
mechanism the slide will revolve with said disk 42 and its pin 53 will operate
through the rod 54 to straighten the toggle and cause the advance of the impression
plunger while its pin 44 will be guided between the hub 47 of the disk on the one
hand and the spring-pressed arm 49 and the cam 48, on the other hand, until a
quarter turn of the disk has been made, when the pin 44 will travel out from
between the hub 47 and the cam 48 into position shown in fig. 26, and will then
rise to the position shown by dotted lines in said figure 26, the slide of course
moving with it, and through rod 54 and toggle 55-56 effecting the retraction of
the impression plunger. It should be here stated that this rising of the slide upon
the release of the guiding pin 44, as just explained, is effected by the action of the
spring 25 (fig. 18) acting upon the yoke 7 and through it and the lever 62 and a
connecting rod 61 upon toggle 55-56, as shown in figs. 2 and 6.
Upon the release of the finger key, the disk 42 will be rotated backward by the
operation of spring 41 applied to shaft 40 and the pin 44 on the slide will travel
down on the outside of the cam 48, the spring arm 49 being pressed out and held out
until the pin reaches the position shown in figure 28 when the spring arm re-acting
will force it inward to the hub 47, as shown in figure 25, thus carrying the slide back.
to the starting point (fig. 24).
In order to secure uniformity in the spacing between characters printed, it is, of
course, necessary that feed mechanism be provided which, after each character is
printed will advance the paper carriage a distance corresponding to the width of
said character, and since in this machine the depression of a key causes the
designation of the next character to be printed and the printing of the character
previously designated, it follows that the operation of spacing for any given
character must be initiated or begun upon the designation of such character and
completed upon the printing of the same. The mechanism which I have devised
for carrying this part of my invention into practice, I will now proceed to
describe.
Upon the paper carriage is formed or attached a rack 117 (fig. 1) which meshes
with a pinion 116 on a shaft 115 that also carries a gear wheel 114 which meshes

page_text: with another gear 113 that drives a pinion 98 mounted loosely upon the lower end of
a tubular shaft 83, see figures 7, 8 and 9.
This pinion 98 forms part of or is attached to a friction rim 97 with which is
adapted to engage friction pawls 93 mounted on a disk 91 formed upon the hollow
shaft 83. The last-mentioned shaft has secured to its upper end a horizontal arm 82
which is adapted for co-operation with a series of stop pins 81 arranged in a dial 81ª,
as shown. The hollow shaft 83 has a bearing 100 at its lower end and through it
passes a shaft 85 which is stopped in a socket 99 on a lever 101, (see fig. 7). A
pin 88 passes through shaft 85 near the upper end of the latter and extends through
a slot 89 in hollow shaft 83, from which it results that the shaft 85 is enabled
to be raised and lowered without interfering with the hollow shaft 83, though
neither shaft can be turned without turning the other also. The pin 88 after
passing through the slot in the shaft 83 extends beneath the flange of a sleeve 76
that bears at its lower end one part 75 of a friction clutch. Above said clutch the
said sleeve is further provided with a locking and lifting arm 77 that is adapted to
engage with a toothed locking rim secured to the lower part of the dial 81 in a
manner to be presently described. To the arm 82 of the hollow shaft 83 is pivoted
a lever 84, the outer end of which stands normally above the raised pin 81, with
which the arm 82 is in engagement, and the inner end of which is connected to
the shaft 85.
Upon a stationary sleeve or bearing 90 outside of the hollow shaft 83 is mounted
a pinion 73 which bears the lower portion 74 of the friction clutch last above
referred to. With this pinion engages a toothed segment 72 that is mounted upon
a shaft 71 and is adapted to be vibrated by the action of the finger keys through
the instrumentality of the arm 70 (fig. 11) a connecting rod 69 (figs. 6 and 11)
lever 66, shaft 65, arm 64ª and cross-bar 64, as will be readily understood.
The lever 101 upon which the vertical shaft 85 is supported is adapted to be
raised and lowered and locked in raised position and unlocked by the co-operating
of two cam levers 107, 109, and an automatic latch 106 (see figure 7). The cam
lever 107 is mounted upon and secured to the shaft 65 and is adapted to be
operated from the finger keys through arm 64" and cross shaft 64 before described,
but the cam lever 109 is mounted upon a separate shaft 34 (fig. 6), which shaft
has secured to it, arms 33, that are connected by a bar 35 and are slotted as shown
at 187 to receive a cross-bar 186, which is adapted to be struck by projections 32 on
the finger keys when the latter are depressed so as to cause the rocking of said
shaft 34.
Sufficient description has now been given of this spacing mechanism to enable a
statement of its operation to be readily understood.
Upon the depression of a finger key the shaft 65 through the medium of the cross
shaft 64 and arm 64ª is rocked forward, and by this motion, two results are
accomplished, to wit, first, the arm 66 is swung so as to draw upon the rod 69, turn
the gear segment 72 (figs. 7 and 11) rotate the pinion 73 and through the coupled
friction clutch 74, 75, rotate the sleeve 76 and cause the arm 77 borne by said
sleeve to travel around with it beneath the dial, and secondly, the cam lever 107 is
swung forward through a portion of its movement; then as the finger key continues
to descend, its projection 32 striking the cross-bar 186 moves downward the arm 33
and rocks the shaft 34, thereby causing the cam lever 109 to swing forward, raise
the lever 101 sufficiently to cause the shaft 85 carried by it to raise the sleeve 76
thereby uncoupling the friction clutch 74, 75, and causing the arm 77 to immediately
pass into engagement with the locking rim 80 at the point to which said arm has
travelled, thus arresting said arm 77. After the locking arm has been thus engaged
with the toothed rim a projection 108 on the still moving cam lever 107 strikes a
roller 104 on the end of the lever 101 and raises said lever 101 still higher, and
until the shaft of said roller is engaged by the automatic locking catch 106.
As the
result of thus further raising the lever 101, the shaft 85 is elevated higher thereby
causing the arm 77 to enter further into the locking rim and raise a stop pin
immediately above it and also causing the arm 84 connected to the upper end of said

page_text: shaft to depress the stop pin with which the arm 82 is engaged and permit the
latter to swing around until arrested by a stop pin in advance of the pin last raised
or previously set up by the raising of the arm 77 into engagement with the locking
rim, the paper carriage meanwhile advancing into position to receive the impression
of the next character brought to the printing point.
Since the various characters employed upon the same printing wheel vary in width
it is necessary that the feed of the paper carriage shall vary correspondingly, in order
that there may be uniformity in the spacing of the letters printed, and inasmuch as
the distance travelled by the stop arm 82 in passing from one stop pin of the dial to
another regulates the distance which the paper carriage is permitted to advance, and
as the distance travelled by said stop arm is determined by the arrest of the locking
lever 77 sooner or later, it follows that if the point at which the locking lever 77 is
arrested can be determined by each finger key as it is depressed, the very desirable
result of having the feed for each character automatically determined by the designation
of such character will be accomplished.
In the present machine, in order to secure this desired result, I have formed the
projections 32 on the keys longer or shorter according to the amount of space required
for the character designated by that key, the keys for designating the widest characters
or those requiring the greatest amount of spacing having the shortest projections and
the keys for the narrowest characters having the longest projections, so that when a
key for designating a wide character is struck a longer interval will take place before
the projection encounters the cross-bar 186 to set in operation the devices for arresting
the arm 77 and thereby permit a greater feed of the paper carriage that when a key
for designating a narrow character and having a long projection is struck, as will be
readily understood.
Inasmuch as each key is designed to be struck for the designation of an upper
ease as well as a lower case character, and as the upper case character require
a greater amount of spacing, I mount the cross-bar 186 in slots 187 in the
arms 33 and connect it by rods 185 to bell-crank levers 184 arranged beneath the
upper case key 176 of the key board (fig. 6). While lower case characters are
being designated, the cross-bar 186 stands near the outer portion of the slots 187
and when struck by the projections 32, gives the arms 33 a throw sufficient to give the
proper spacing for such character, but when an upper case character is designated
the depression of the upper case key 176 required for such operation causes the said
cross-bar 186, through the action of the bell-crank 184 and rod 185 to be shifted to
the inner ends of the slots 187 so that when the key corresponding to the character to be
designated is depressed, its projection 32 will strike said cross-bar 186 later and
by so doing permit a greater feed of the carriage to take place.
Where the upper case character is of much greater width than the lower case
character, adapted to be designated by the same key in which case a much greater
feed is required, the projection 32 is cut away as shown (fig. 6") so that the engage-
ment of said projection with the cross-bar 186 will be still longer delayed and thus
insure the necessary increase in feed.
Adjoining the type-wheels is located an inking cylinder 164ª (figs. 1, 4, 5 and 18)
the inner circumference of which is supplied with printer's ink in any suitable
manner. Into this cylinder projects a vertical shaft 160 which has a lower
bearing 161 and is enclosed at its upper end by a sleeve 162 upon which is mounted
an arm 163 carrying an inking wheel 164 as shown in fig. 18. A pin 165
projects from the shaft 160 through a straight slot 166 in the sleeve 162 (see
Figs. 18-19) and through a curved slot 167 in the hub of the arm 163 (figs. 18, 19
and 20). A friction rim 157 provided with a gear 156 is mounted loosely upon the
sleeve 162 and is adapted to co-operate when rotated in one direction, with friction
pawls 158 pivoted to a disk 158ª (figs. 18 to 21) secured to the said sleeve 162.
A gear segment 155 is connected to the pivot or shaft 121 to which the hand lever 118
is secured and meshes with the pinion 156, as shown in dotted lines, figure 1.
When the hand lever 118 is drawn forward to return the paper carriage to starting
point, the friction rim 157 is rotated in the direction indicated by the arrow, Fig. 21,

page_text: and engaging with the friction pawls 158, causes the sleeve 162, and through the
pin 165 the arm 163 and inking roller 164 to be also rotated. The inking roller
in moving around, travels in contact with the inner surface of the inking cylinder,
receives the ink therefrom and halts at the opening in the side of the cylinder into
which the periphery of the type-wheels project and in contact with the type-wheel
which happens to be in position for printing. As the type-wheel revolves the ink is
transferred to the characters upon its periphery and is equalized and distributed by
means of a distributing roller mounted in the spring-pressed arm 171, as shown in
figure 1.
When the hand lever, under the influence of the spring 118ª applied to it as
shown in figure 2 is returned to normal position after being pulled forward as
described, the friction rim 157, through the described connections, rotated in reverse
direction disengaging the pawls and leaving the sleeve and the connected arm and
inking wheel stationary.
In order that the type-wheels may be shifted up and down without interference
from the inking roller, I connect to the rod 173 which effects the shifting of the
type-wheels, a lever 169, pivoted at 169 and having a bifurcated end which engages
with a grooved collar 169 on the shaft 160 of the inking apparatus, as shown in
figure 18.
When the rod 173 is raised to shift the type-wheels, the shaft 160 is lowered
and its pin 165 moving down the curved slot 167 in the hub of the arm 163
that carries the inking roller, causes said arm to be moved slightly to one side so
as to momentarily withdraw the inking roller from contact with the upper type-wheel
and bring it back into contact with the lower type-wheel by the time the shifting
-operation has been accomplished. Of course, when the type wheels are lowered,
the described operation of throwing the inking roller into and out of contact is
repeated.
The outer end of the arm 171 which carries the distributing roller 170 is normally
engaged with a notch 172 in the rod 173, and when the said rod is shifted said arm is
forced out of said notch, thereby withdrawing the distributing roller from contact
with the upper type-wheel and causing it to remain out of contact until the shifting
operation has been completed, when the arm 171 will drop into another similar notch,
thus bringing the distributing roller into contact with the lower type-wheel. This
movement is effected each time the shifting operation takes place.
In the use of this machine, the last letter of a word designated is printed by striking
the space or blank key.
This leaves the machine with the stop pin 20 (fig. 18) corresponding to the space
or blank key set up, the arm 16 in contact with said pin, the space on the type-
wheel at the printing point, while the stop pin of the feeding mechanism corresponding
to the character last printed, and the stop pin corresponding to space, is left set
up, the arm 82 in engagement with the last mentioned stop pin and the arm 84 above
it, as shown in figure 7.
Assuming the machine to have been so left and that it is desired to print the
word "The," the operation will be as follows:-
The operator will, with one hand, depress the upper case key 176 (fig. 6) which
will cause the type wheels to be raised so as to bring the lower wheel 4 into printing
position and be there locked by the automatic operation of the spring-pressed bell-
crank lever 178 and pin 177, said bell-crank lever assuming the position shown in
dotted lines figure 6. As a further result of depressing the upper case key, the bell-
crank levers 184 will be rocked, and through rods 185, will cause the cross-bar 186
to advance to the inner portion of the slots 187 in the arms 33.
While the upper case key is kept depressed, the operator will then, with his
disengaged hand, depress the finger key employed to designate "T" which will
effect the following movements, first, the projection 32 on the key will rock the
corresponding lever 27 and raise the corresponding pin 20 in the dial 21 ; secondly,
the shaft 65 will be rocked through the instrumentality of rods 64 and arms 64° and
the arm 36 (figure 2) and draw upon the rod 37, thereby rocking the shaft 40 and,

page_text: through the described connections (figs. 22 to 28) cause the toggle 55-56 to be
drawn downward, thereby causing connecting rod 61 (fig. 6) to swing down the
arm 62, and by the latter cause the locking yoke 7 (figure 18) to engage with the
locking wheel 8 and hold the type-wheel stationary and depress, by the arm 14,
the stop pin with which the arm 16 is in contact and permit said arm to advance
beyond said pin; and as a further result, the toggle 55-56 will be further
straightened; thirdly, the arm 66 on the shaft 65 will draw upon the rod 69 thereby
vibrating the gear segment 72 (figs. 7 and 11) and, through the pinion 73 and
clutch 74, 75, cause the arm 77 to swing around under the dial of the spacing
mechanism; fourthly, swinging cam arm 107 will be started in motion (fig. 7);
fifthly, the projection 32 on the finger key will strike the cross-bar 186 and through
the arms 33 and shaft 34 swing forward the cam lever 109 and cause it to raise the
lever 101, lift the shaft 85, thereby raising the arm 77 into engagement with the
circular locking rim 80 and arresting the rotation of said arm and uncoupling
the friction clutch 71-75 (as shown in figure 8); sixthly, the projection 108 on
the cain 107 will strike roller 104 on the lever 101 and raise the last-mentioned
lever into engagement with the locking catch 106, (figure 9) the said lever 101 in
thus further rising causing the arm 84 to depress the raised pin beneath it (which
is the one that was set up by the striking of the key designating the character
printed when the space key was struck) and release the arm 82 and permit it to
swing around into engagement with the stop pin which was set up upon the striking of
the key for the designation of a space, thereby permitting the paper carriage to advance
a distance equal to the space previously designated and at the same time cause the
arm 77 to raise the stop pin which is to regulate the feed for the letter "T";
seventhly, the toggle will be completely straightened out (as shown in figure 23) so
as to give a dead stroke to the slide carrying the impression surface, and will then
immediately resume normal position as shown in fig. 22, thereby causing the lever 62
to be lifted through the connecting rod 61 and permitting the locking yoke 7 (fig. 18)
to rise, release the type-wheel shaft and allow the arm 16 to swing around into
engagement with the stop pin set up by the striking of the key and the character "T"
on the type wheel to be brought to the printing point.
Upon the release the depressed key, the spring 41 on shaft 40 (fig. 2) which
was compressed upon the depression of the key will assert itself and through the said
shaft 40 bring the slide 43 and connected parts (figure 24) back to normal position,
the spring 71 on the shaft 71 will rotate said shaft and vibrate the gear segment 72
thereon backward and, through the pinion 73, rotate the part 74 of the friction
clutch back to the starting point; the can armis 107 and 109 by the springs con-
nected to their respective shafts, will be rocked backward, and a pin 110 on the cam
arm 107 will strike the lower end of the latch 106, disengage said latch from the
lever 101 and permit said lever to swing down; springs 78 mounted on pins 78
connected to the arms 77 operating to depress the shaft 85, withdraw the said arm 77
from engagement with the toothed rim on the dial and bring the part 75 of the
friction clutch again into connection with the part 74 of said clutch.
Having thus set up, as it were, the letter "T" and provided for the proper feed of
the paper carriage, consequent on the printing of said letter, the "h" key is struck,
thereby printing the letter "T," setting up the letter "h" and causing the paper
carriage to feed forward a distance equal to the width of said letter "T," all the
movements of the mechanism which resulted from the striking of the "T" key being
repeated except that the closed latch 181 is struck by the arm 183 so as to swing the
bell-crank lever 178 from beneath the pin on the rod 173 and permit the type-wheels
to descend and bring the upper type-wheel, which is the one bearing the lower case
characters, into the printing plane.
Upon the "e" key being now struck, the letter "h" will be printed, the paper
carriage fed forward and the letter "e" and its feed set for operation, the move-
ments of the mechanism being repeated as before, except that the position of the
type-wheels is not changed, the lever 183 passing and repassing the latch 181 without
striking it,

page_text: To complete the word "The," the space key is struck, the letter e" printed, the
paper carriage fed correspondingly and the space and the feed therefor, set up.
In the use of the ordinary type-writing machine when a key is struck, the character
corresponding to that key is immediately printed, and if a wrong key happens to be
struck, there is no way of correcting the error made on the record except by erasing
the character, adjusting the paper carriage back and printing the proper character
over the place of the erasure, an operation both delicate and inconvenient it requiring
some skill to secure the printing of the letter at the right point and the record left,
presenting, at best, a botched and uneven appearance.
The new principle of operation introduced by my invention, to wit, the printing
of one character upon the designation of the next succeeding one, enables me to
successfully make corrections of errors due to the striking of wrong keys before any
record of the same has been made on the paper. Experience with ordinary styles of
type-writers demonstrates that an operator is usually conscious of having struck_a.
wrong key immediately after he has done so, but too late of course, to prevent the
record on the paper.
I have, therefore, in carrying out my new method or process of printing provided
means whereby when, in the attempted designation of a letter, a wrong key is struck,
the operator may, by the pressing of a stop or key, momentarily arrest the operation
of the type-wheel and paper carriage and by the striking of the proper key depress
the pins set up in both the type-wheel and feed mechanism dials by the striking of
the wrong key and simultaneously set up the proper pins in said dials and thus
by the re-adjustment of such mechanism enable the proper letter to be printed and the
proper feed for said letter to be made when the next character is designated.. The
mechanism by which this correcting operation is enabled to be performed will now be
described.
Referring now particularly to figures 1, 2, 6, 7, and 13, 188 represents a push rod
the outer end of which extends above the key board and terminates in a button
(figs. 1 and 6) and the inner end of which is connected to an arm 189 secured to a
sleeve 195 and having a concaved portion 189ª which is adapted when the rod is
pushed in, to bear against the periphery of the friction rim 97. The sleeve 195 is
surrounded by a spring 196, the tension of which is exerted to keep the arm 189
and rod 188 retracted.
A shorter arm 193 is formed upon or secured to the sleeve 195 and carries a pin 194
which extends up alongside of a toothed segment arm 191 secured to a shaft 190
that passes through the sleeve 195.
This segment 191 meshes with the pinion 95, that is secured to, so as to rotate
with, a friction rim 96 mounted loosely on the hollow shaft 83 and adapted to
co-operate with friction pawls 92 pivoted to the disk 91 on said hollow shaft 83.
A spring 192 secured at one end to the arm 189 and at the other end to the segment
arm 191 operates to keep arm 191 against the pin 194.
The striking of the wrong key, of course sets up a pin in the type-wheel-
controlling dial, as well as a pin in the dial which controls the feed of the paper
carriage.
In order then that the pin thus wrongly set up in the carriage-feed-controlling.
dial may not be permitted to cause an improper feed of the paper carriage, the
rod 188 is pushed in which forces the arm 189 up against the friction rim 97 and
causes it to act as a brake thereto and at the same time winds up or puts under
tension the spring 192.
Upon now striking the proper key, the arm 77 will be swung around to the proper.
point, the shaft 85 will be partially raised so as to engage said arm with the toothed
rim of the dial, and will then be fully raised so as to cause, through the lever 84, the
depression of the stop pin with which the arm 82 is in engagement and also the
raising of the pin immediately above the said arm 77, after which the hollow
shaft 83 will be rotated to swing around the arm 82 into engagement with the
stop pin which was improperly set up, such rotation being effected, not ly the
operation of the spring-impelled paper carriage through the friction rim. 97 and

page_text: the described connections, (for as has been seen, the said friction rim is held
stationary and the paper carriage prevented from being fed by the action of the
brake lever 189) but, by the compressed spring 192 operating through the medium
of the segment arm 191, pinion 95, friction rim 96 and pawls 92. The distance
between the pin with which the arm 82 is now engaged and the pin just set up is such
as will insure the proper spacing of the last designated character, in other words, the
feed provided by the shifting of the arm 82 from the pin with which it was
engaged, to the next pin in the dial resulting from the striking of the proper key,
is, by the operation of the push rod and the striking of the proper key nullified or
wiped out, the arm 82 is advanced to the pin which was set up when the wrong key
was struck and another piu is set up further around on the dial at such distance
from the last-named pin as will insure the proper advance of said arm 82 and the
proper feed of the paper carriage when the right or substitute character comes to
be printed.
Connected to the push rod 188 is a rod 197 (figs. 2 and 6) which rod is also
connected with a crank 198 on a rock shaft 199. This rock shaft in turn carries
an arın 200 that is adapted to bear upon a flange or collar 13 of the sleeve 12 (figs. 6
and 18): The pushing in of the rod 188 to correct an error causes the shaft 199 to
be rocked and the arm 200 to depress the sleeve 12, thereby lowering the yoke 7 and
locking the type-wheels from rotation, at the same time depressing through the arm 14,
the stop pin 20 corresponding to the key wrongly struck, and then when the right
key is struck the stop pin corresponding to that key will be set up in the dial and
when the push bar is released the arm 16 will swing around and become engaged with
the said last-mentioned pin, thereby bringing the proper letter to the printing point.
During the correcting operation, and while the key corresponding to the substituted
character is being depressed, it is of course necessary, not only that there shall be uo
feed of the paper carriage and no change in the numerous operations of the type-
wheel adjusting mechanism, but also that there shall be
no operation of the
impression devices to print the character that happens to be at the printing point.
To the shaft 199, that serves as an instrumentality in locking the type-wheel
during the substitution of the right or wrong pin, I secure an arm 201 and connect to
this arm a rod 202 (fig. 2) which has at its opposite end a slot 203 into which projects
the pin 53 on the slide 43 of the impression mechanism (figs. 22 to 24).
In the normal operation of the machine, the pin 53 plays freely back and forth in
slot 203 and the operation of the impression devices is not therefore affected by said
rod 202, but when in the correcting operation, the shaft 199 is rocked by the push
bar, the arm 201 is swung backward and thereby causes the end of the slot 203 to
bear against the pin 53 and force the slide in its guide, until the said pin coincides
with the center of the shaft 40 as shown in dotted lines, fig. 22, so that when the
shaft 40 is rocked, by the operation of the key employed in designating the correct
or substituted letter, no motion of the connecting rod 54 jointed to said pin 53 will
take place and no reciprocation of the impression slide effected, and hence no
impression made.
It will be noticed that the same hand lever which aids in winding up the type-
wheel propelling mechanism, is also employed to bring back the paper carriage and
wind up its propelling mechanisın. The connections between the lever and said two
propelling mechanisms, are however, of necessity made flexible and independent (cords
being preferably employed) so that when the lever is operated, each propelling
mechanism will be re-wound to an extent required by the amount of work it has done
since the last movement of the lever.
It will be further noticed that my letter space feed mechanism embraces means
for setting the feed for a given character, upon the designation of such character
through the medium of a finger key, and means for executing the feed for the character
designated upon the designation of the same or another character through the medium
of a finger key. In short, a primary and secondary impulse are required to designate
and complete the feed for any given character and for convenience, this group of

page_text: nstrumentalities will be referred to in the claims as double-impulse-letter-space-feed-
mechanism.
It will also be observed that the arm 77, operates to set a pin 81, in the feed dial,
thereby designating in advance the space required for the letter to be printed, upon
the designation of a subsequent character. This arm moves forward intermittently
by variable steps, according to the width of the letter to be printed, and thus becomes
an intermittently rotating designator for designating the feed spaces in advance.
Where my invention consists in the combination of two or more groups of elements,
I wish it to be understood that I do not confine myself to the particular train.or
