Improvements in Type Writing Machines.
I, CHARLES THOMAS MOORE of Washington, District of Columbia, United
States of America, Lawyer 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:-
or
This invention relates to that class of type writing machines in which a rotable
type wheel having on its face or periphery, letters or characters from which to
print, is adapted to be arrested at the printing point by the operation of a finger
key corresponding to the character desired to be printed, but instead of printing
impressing on the paper the character designated by the key depressed, as is usually
the case, 1 print by the depression of such key the character designated by the
depression of the last previous key operated upou and set the machine so that it
will print in turn said last designated character upon the designation of the one
next succeeding it, by which I am enabled to secure greater uniformity in the
printing and a higher rate of speed.
I also so arrange my paper feeding devices as to cause an advance of the paper
proportioned to the width of the characters printed and I preferably provide
suitable contrivances for applying ordinary printing ink to the type wheel thereby
securing print which cannot be distinguished from that ordinarily produced by the
printer with the usual appliances.
There are many other important principles involved in my machine, which I will
not at this point consider, deeming it more advisable to first describe the machine
and its operation at length, and then point out its several features of novelty in
the claims at the close of this Specification. :/

Figures 14 and 15 are detail views.
Figure 16 is a view of the means for winding the spring which rotates the type
wheel shaft, by the backward movement of the carriage.
S, represents the type wheel shaft upon which are loosely mounted two type'
wheels E', E', connected by a hub Ax and prevented from independent rotation
by rods d 2 passing through them and secured to collars d 3, d3 fixed' to the shaft
(Figure 2). These type wheels E', E 2 are provided on their peripheries with upper

page_text: and lower case characters, respectively. The upper portion of the type wheel
shaft, is 'made hollow to receive a rod or shaft I, and is slotted at S¹ to permit of
the movement of a yoke 1' which passes through the said shaft I and is secured at
opposite ends to the upper type wheel E 2. Connected to the shaft. I at F6, is
the bent end L2 of a vertical rod L¹ which is guided at F 5, A 2 and T3
(Figure 2). Near the lower end, this rod L' has a pin T4 and below this pin, is
mounted a sleeve T' to which is connected one arm of a toggle T, T2, the other
arm being connected to the step T3. A rod L connects the toggle T, T2 to a
frame B 2 that extends from side to side beneath the key board, and has a slight
lateral motion in guides H3, H 3 being normally pressed backward by
springs H', H. The lower arm of bell crank levers B pivoted to the frame, is
provided with a slot in which projects a pin on the frame B 2, while the upper arm
of said levers has bearing upon it, a bar B secured to arms Br pivoted at 10,
(Fig. 2).
The frame B2 has two series of spring pins p2, p3, one series p2 occupying
normally a position immediately beneath pins p projecting from the underside of
the keys K. When the pins p2 are thus beneath the pins the frame B 2 is held
pressed back by the springs H', and the upper type wheel, (which is the one on
which the lower case characters are arranged) is opposite the presser bar P of the
paper carriage and remains there so long as the lower case characters are to be
printed.
When, however, it is desired to print upper case characters the bar B, is pressed,
causing the bell crank levers B' to move forward the pin frame B 2 and bring the
pins p3 beneath the pins p² causing the connecting bar L to straighten out the
toggle arms T, T 2, and thus, through the intermediate connections, raise the type
wheel E bearing the upper case characters to the printing point.
Each time the rod L is lifted to bring the lower type wheel in position for
printing, a pin i upon said rod strikes and passes one arm of a pivoted bell crank
lever h, said lever being returned by a spring 4 and serves by supporting the said
pini, to maintain said type wheel in its adjusted position, where it remains until
the next key is pressed, when said bell crank lever his thrown out of engagement
with the pin by the action of a pin wheel ', co-operating with its lower arm, and
a rod g bearing a pawl acting upon a ratchet secured to said pin wheel and itself
actuated by a lever F attached to a bar F extending beneath the finger keys.
i
For imparting rotary movement to the type wheel shaft and the type wheels
thereon and for effecting the starting and stopping of the same, I provide a barrel 62
mounted in fixed bearings and with the type wheel shaft passing loosely through it
containing a helical spring which is secured at its inner end to the type wheel shaft
ard at its outer end to said barrel 62. A pinion secured to said barrel 62,
meshes with a larger gear wheel W fixed to a shaft S3. This shaft S3 has a
barrel bloosely mounted upon it, containing a helical spring stronger than the
spring within the harrel 2 and secured at its inner end to the shaft S3 and at its
outer end to said barrel b. Above the barrel B' and mounted upon a fixed
sleeve $2 through which the shaft S3 passes, is still another barrel b containing a
spring having its outer end secured to said barrel b and its inner end to said fixed
sleeve S2. Connection is made between the barrels b, 1, by means of a ratchet ỗ x
formed upon the upper portion of the barrel b' and a pawl bxx mounted upon
the barrel band engaging said ratchet, as shown in Figures 2 and 16, and connection
is made between the barrel band a reciprocating paper carriage N, by means of a
rack bar R secured by arms R' to said carriage (see Figures 2 and 4) andia pinion n
formed upon said barrel b and meshing into said rack bar.
Each time the reciprocating paper carriage is brought back to starting point,
after having completed the movement in front of the type wheel (which may be
done by hand or by a foot lever operating through a cord or chain C5, Figure 3)
the rack R through the pinion n, winds up the spring within the barrel b and the
said barrel operating in turn through the pawl and ratchet connection bx,
b before referred to, causes the spring within the barrel b to be also wound up
2

page_text: and to operate through shaft S 3, wheel W, and piniön n¹ to turn the barrel 62 and
wind up the spring contained within it that acts directly upon the type wheel
shaft S.
It will be understood that by reason of the series of springs b³, b', and b,
arranged and operating as described, the type wheels will be given their impulse
and be caused to revolve by the action of the spring & which is applied directly
to the type wheel shaft.
It will of course, he understood that the spring in 6 is relied upon to feed the
paper carriage forward whenever a stop in front of said carriage is released.
The lower end of the type wheel shaft passes centrally into, and has a bearing in
a circular dial D. This dial has arranged around it, a series of pins e, as many in
number as there are keys to the key board and characters upon either of the type
wheels. Each of these pins is provided with a slot Ee in its outer edge into which
projects a shoulder e rx from the body of the dial, to enable the pin to have a
limited sliding motion vertically. Each piu has a beveled upper end and a
shoulder e 2 (Figures 9 and 10).
Immediately beneath each of the pins of the dial is arranged the bent end k, of
a lever K 2, pivoted at 3, to a suitable fulcrum or support upon a fixed cross
bar A 2. These levers K 2 are arranged as in Figure 5 and each one is adapted
to be actuated from one of the keys K of the key board by means of a pin p
(Figure 2).
When any one of the keys K is depressed, the pin p depresses one end of the
lever K 2 beneath it and throws up the other bent end k of said lever and causes it
to force upward the appropriate dial pin above it, while upon pressure being
removed from the key, the lever K2 will drop back to its normal position.
Loosely mounted upon the type wheel shaft is an arm a the free end of which is
adapted to engage with the shoulder e 2 of one or the other of the dial pins e
when the latter is elevated. Above this loosely mounted arm a is another arm a¹
rigidly secured to the shaft and having interposed between it and the swinging
arm a, a light yielding spring a xx as shown in Figure 13.
H
A vertically swinging arm a 2 pivoted by a horizontal pivot to a short extension
of the arm a, is formed with or connected to, a sleeve or collar a car which
encircles the type wheel shaft.and above this collar is a sleeve a 4, loosely mounted
on the shaft and bearing upon the collar a aca and having turn bearing upon it,
the end of the lower arm of a bell crank lever G¹ pivoted to a fixed support G2
shown in Figures 2 and 14.
The upper arm of the bell crank lever G' is connected by a link J to a
rod G supported in vibratory arms F 2 pivoted at 5 to a bracket. Each of the
arms F 2 is provided with a cam groove f2, in which works a pin 4 on the end
of a lever F pivoted at 2 and connected, at its opposite end, by a bar F extending
transversely of the key board and beneath it to a similar lever on the opposite side
of the machine.
One of the pins e of the dial is always.in an elevated position with the free end
of the swinging arma against its shoulder e 2, being held there by the tension of
the spring applied to the type wheel shaft.
The free end of the vertically swinging arin a 2 normally stands just above the
upper end of said raised pin.
Assuming then, one of the pins to be elevated and the type wheel shaft arrested,
if one of the keys of the keyboard is depressed, the dial pin corresponding to
said key will be raised through the end of the lever K 2, while at the same time,
the arm F 2 by the action of the pin 4 on the lever Fin the angular portion of
its cam groove will be vibrated, thus causing the bell crank lever G' to be rocked.
first forward and then backward, the forward motion causing the vertically swinging
arm a 2 to bear down upon the upper end of the previously elevated pin and to
depress said pin. Before, however, the said pin has been sufficiently depressed to
release the swinging arm a from its shoulder e 2, the ends ma of two arms m³, m³
secured to the sleeve a 4 pass in between teeth of a locking wheel E secured to the

page_text: =
type wheel shaft, shown in Figures 2 and 3, and prevent the shaft from rotating,"
but as soon as the pin has been depressed sufficiently far to release the said swinging
arm a, from the shoulder e 2 the spring a ex operates to throw said arm a, past the
shoulder e 2 to an extent, however, limited by a stop a 5 on the arm a'. Upon the
backward motion of the bell crank lever G¹ referred to, the vertically swinging
arm a 2 is thrown upward by the operation of a spring A 7 shown in Figure 2
carrying with it the sleeve a 4 and effecting the release of the locking wheel e from
the booked ends ma of the arms m³, m³, thereby permitting the type wheel shaft to
rotate until the arm a strikes the shoulder e 2 of the pin last elevated, this operation
being repeated each time a finger key is depressed.
The paper carriage N is provided with friction rollers R2 R 5 and is adapted to
travel back and forth in front of the type wheels upon guide rails R3 R4 with
which said rollers engage.
The presser bar P is provided at opposite ends with arms P 2 which permit of
said bar being reciprocated back and forth, transversely, of the paper carriage
toward and from the type wheel by the operation of the vibrating arms F2
through the shaft G and swinging arms F 3 hung at. F4 to brackets on the
paper carriage and connected near their middle at N2 to the arms of said
presser bar.
A paper rest P is pivoted to the arms P2 of the presser, bar and its lower
edge is curved so as to fit the under portion of the presser bar, a spring P 3
being employed to keep said edge up to the presser bar with yielding pressure.
The feeding of the paper is effected by the rotation of the paper cylinder C.
On the end of said cylinder C is secured a ratchet wheel t, with which is adapted
to engage a spring pawlt mounted upon an arm 2 pivoted at t3 to the paper
carriage and actuated by a rod 5 which is in a slotted arm t4 secured to the
paper carriage N.
The lower end of the rod t5 is provided with an eye or
opening in its lower end through which passes a crank arm t6 projecting from an
oscillating shaft t7. Motion is communicated to said shaft 7 and to the pawls
connected thereto through a rod 8 connected to a finger key Q, all as shown in
Figures 4 and 7.
After each line has been printed upon the paper, the finger key Q may be
depressed, thereby causing the paper cylinder C to be rotated to advance the paper.
It will be noted that the crank arm t6 extends from side to side of the machine and
that although the rod t 5 slides back and forth with the paper carriage, its connection
with said crank arm t6 is preserved.
The paper cylinder rotating mechanism is generally operated automatically by a
bell crank lever t9 pivoted to a depending bracket N 2 and a stop N 5 secured to
the paper carriage and adapted, upon the return movement of said carriage, to strike
the upper arm of said bell crank levert 9 and cause the lower arm thereof to operate
upon the crank arm 6 as shown in Figure 15.
M5 (Figures 1, 6 and 12) is a frame secured to the upper left hand portion of
the machine. Within this frame are arranged a series of sliding bars or what may
be termed quads. These quads are formed with reference to the width of the type
on the type wheel, one of them corresponding to the width of the narrowest type, two
of them to the width of type of next size and three of them to the width of the
largest type, and the function which they perform in the machine is, after an
impression has been made from a given type, to cause the paper carriage to advance
a distance equal to the width of said type and bring it in position for receiving, at
the proper point, the impression of the next type. The thickness of these quads
may vary and two or more be employed to represent the smallest type and a
relatively larger number for the largest type.
VVV represents three pawls of different lengths having hooked outer ends and
pivoted at their inner ends to arms V 3 of a sleeve M 3 which is mounted so as to
slide freely upon a rod B 9. Each of these pawls is adapted to engage with one
of the sliding quads q and to prevent the possibility of more than one quad being
caught at a time, the quads are preferably tapered at their upper and lower edges.

page_text: 1
This tapering of the cages or the quads also reances the area of the frictional
Surface of their sides.
V is another and shorter pawl pivoted to a rearwardly extending arm V 4 of
the said sleeve AI 3 and having a pin or projection V 5 at its outer end as shown
in Figure 6. Each of the quads q, has a notch V 2 on its upper edge near its
middle. with which the pin of the short pawl Vis adapted to engage. The
shaft B 9 carrying the sleeve M 3, is reciprocated back and forth transversely of
its length, upon guides M M by means of rods B7 B7, mounted upon the upper
arms of bell crauk levers B 6, B6, pivoted to a cross-shaft B11, the lower arms of
said bell crank levers being connectel by rods B5 to levers B 4 at.5 and connected
by a bar B 3, (Figure 2).
M 2 is a metal piece or bracket at one end of the paper carriage N, (Figures 1
and 6) and having pins C4 C5, which pass through guide perforations in the
carriage frame N and having also a short stud C-3 adapted to project in the plane
of the quads g when the latter are projected and a long arin M8 which rests
within a groove in the sleeve M.3 and bears at its extremity the roller M 4. Upon
the pin C5 is arranged a spiral spring, which hears at one end against a collar ce
on said rod and a lug cy. The tendency of this spring is to throw the piece_or
bracket M 2 out, away from the paper carriage frame N so that its projection C 3
shall be in advance of a projection N¹ formed on said paper carriage and likewise
projecting into the plane of the quads when the latter are thrown outward.
Referring now to Figure 2, it will be seen, that whenever a finger key is depressed
for the designation of a letter its pin p' will depress the spring pins p 2 or 3 as
the case may be, beneath it and said pin p 2 or 3 will in turn depress the bar B3
and cause the rod B 9 to be pushed forward through the medium of the bars B4,
rod B 5, bell crank levers B6 and rods B 7. In thus moving forward, the bar B9 will
carry with it the sleeve M 3 thereby causing the hooked ends of one or more of
the pawls, V, V, V to engage with the end of the quad or quads beneath them
accordingly as more or less motion is given the bar B 3, then upon the finger key
being released, the said pawl or pawls V will be drawn backward carrying with
them one or more of the quads out of the path of the projection C 3 of the piece
or bracket M 2 on the paper carriage, but not out of the path of the projection N¹
of the paper carriage, since the latter projects further than the projection C 3.
As soon as the end of the quad or quads is withdrawn from the projection C 3, a
shoulder V 6 on each of the pawls by which the withdrawal of said quads is
effected strikes a rib or bar M 15 on the frame M 5 and the said pawls are
disengaged from the quads, and, at the same time, the pin of the spring C 5
operates to force the piece or bracket M 2 out from and in advance of the paper
carriage and causes said projection to engage with the end of the quad next
following the quad or quads withdrawn. If the letter designated is of the medium
idth, the depression of the key will cause one of the shortest spring pins in the
frame B2 to act upon the bar B3 and thus give the minimum amount of forward
movement to the pawls V, V, V, and cause the longest only of said pawls to
engage with and retract a quad, while the designation of the wider letter will
cause a pin in the pin bar made correspondingly longer-to throw two or even
three of the pawls V into engagement so as to retract two or three of the quads.
"1
The three pawls V are made of different lengths, to correspond to the pius of
different lengths in the pin frame B2 and whenever a key is depressed, to
designate a letter of any one of the three widths, one or all of the pawls operate
to withdraw partially a number of quads corresponding in aggregate thickness
to the width of the letter desiguated. I state that said quads are partially
withdrawn, by which I mean that they are withdrawn far enough to be moved
out of the path of the projection C 3, but not sufficiently far to withdraw them
from the path of the projection N', the latter still remaining in engagement with
them.
After the quads have been partially withdrawn or set up so to speak, upon the

page_text: designation of a letter and the next letter is designated, the pressure of the key
corresponding to said next letter, causes all the pawls V and the pawl V₁ to
be advanced, the former operating to engage with the appropriate number of
quads while the pin V 5 of the latter rides along the upper surface of the quad or
quade set up by the previous operation, and then upon the pressure being removed
from the finger key, all the pawls are retracted, the longer ones partially with-
drawing or setting up the quads for the letter last designated, while the pin V 5
of the short pawl V₁ falls into the notch or notches V 2 of the quads partially
withdrawn or set up by the previous operation, and becoming thus engaged with
said last mentioned quads,.operates to fully retract them and carry them out of the
path of the projection N' of the paper carriage, thereby permitting the paper
carriage to be advanced or fed forward under the influence of the helical springs
within the drums b, until the projection N' comes in contact with the quads last
set up, the extent of such feed of the carriage being equal to the thickness of the
quads thus completely withdrawn.
Upon the bar B3 through which the motion of the vertically moving spring
pins p 2, p 3 is communicated to the lever B4, 1 may arrange an angular plate f
having a slight longitudinal back and forth movement on said bar B3, being
actuated in one direction by a stop f2 upon the frame and in the other by a
spring 3 secured at one end to the frame and at the other to said plate f. This
plate is provided with a series of openings p8 in its upper portion, which
normally stands directly beneath and in line with the spring pins p 2 of the bar 12
and when any one of said spring pins is depressed, its lower end passes into one
of these openings and bears against the bar 13 thereby causing the latter to
descend. As soon as the bar B 3 begins to move downward, the end of the plate f
strikes the stop f2 and causes the said plate to be shifted against the tension of
the spring 3 and the edge of its opening to enter a groove in the side of the pin,
as shown in Figure 11, thus securely holding the pin connected to the bar B3,
until the finger key rises, when its disconnection will be automatically effected by
the spring 3 as will be readily understood. The advantage of employing this
locking plate is that it absolutely limits the stroke of the bar B3 to the length of
the depressed pin between its head and the frame B 2 and prevents the jumping
of the bar when the keys are struck with unusual force.
The mechanism for inking the type wheels, is as follows: Referring to Figures 1
and 3, 10 represents a hollow cylinder divided into an upper and lower compart-
ment, by a partition 15, and 14 is another smaller cylinder arranged alongside
the first named and adjacent to the type wheels. Centrally of the cylinder r 10 is
arranged a shaft 3, which has secured to it, near its upper end, an arm r2 bearing
at its outer end a ruller which is adapted when the said shaft r3 is rotated to
revolve around in contact with the inner periphery of the cylinder 10 and to
come back into contact with the inking roller r, mounted on an arm u pivoted at u
to the casing A, which encloses the type wheels. Ordinary printers ink is applied
to the inner surface of the cylinder 10 and the roller operates to evenly
distribute it and to transfer it to the roller r, which applies to the type
wheels.
Mounted loosely upon the shaft 3, uear the lower end thereof, is a fatchet
wheel 5 to which is secured a barrel r4, containing a helical spring which is
connected at one end to said barrel and at the other end to said shaft r 3. A
pawl 7 mounted upon a reciprocating bar r8 is adapted to engage with the ratchet
wheel 5 and wind up the spring within the barrel r4, while another pawlr 6,
serves to prevent backward rotation of the barrel when said spring is wound.
Motion in imparted to the bar r8 by a crank arm r 16 secured to the shaft B 11,
to which the bell crank levers B6 are also secured, as before described (see
Figure 2).
Also secured to the shaft r3 is a fixed arm 13 which normally is in contact with
a swinging tripping lever or catch 12, shown in Figure 3, being helil in
r

page_text: engagement therewith by the stress of the spring applied to the shaft. The lower
end of this tripping lever stands normally in the path of a cam or projection & 9 on
the barrel 4.
2"
The operation of these parts is as follows: Each time the shaft B 11 is oscillated,.
as the result of the depression and release of a finger key, the bar 8 through its
pawl 7 acting upon the ratchet 5 causes the barrel r4 to be rotated the distance
of one tooth and the spring within it to be correspondingly wound up and by the
time the barrel bas made one complete revolution, the spring is completely wound
up and the cam r 9 is brought to the point where it strikes the tripping lever r 12
and vibrates it, so as to release the arm r 13, whereupon the shaft 3 is permitted
to make one complete revolution or until again arrested by the reengagement of the
rod r 13 with the tripping lever; and during such rotation the distributing roller ¹
passes once around the inner periphery of the inking cylinder 10 and back to
contact with the inking roller r. I form in the shifting rod L' (see Figure 2)
two V shaped notches O, O and cause the shorter end of the arm which bears.
said inking roller to normally bear against the said rod L'. When either type
wheel is in printing position, the said arm « will be entered in one or the other of
the notches O, O and the inking roller will be permitted to bear against the
periphery of such type wheel. But whenever sail rid L' is shifted for the purpose-
of changing the position of said type wheels, the said arm u will ride out of the
notch and swing sufficiently to remove the inking roller from contact with the type
wheel and remain out of contact until the shifting operation is completed when the-
next notch is brought into position.
At the end of each use of the machine, or in other words the completion of the
printing of the particular matter being transcribed, the operator to print the last
letter designated, strikes the space key of the key board which causes tho
corresponding pin of the dial and the corresponding space quad or quads to be set
up, then the driving of the paper carriage back to position to begin a new line of
matter whether done then or at the next use of the machine effects through the
roller M4 the automatic restoration of said quad or quads to their normal positions,.
and adjusts the machine so that upon the depression of the first key at the beginning
of the new line the paper carriage will not be advanced at all, but will remain
stationary until the second letter is designated. Suppose it is desired to write the
word "The" at the beginning of a line; the operation will be as follows: The
operator will first press upon the bar B which will cause the frame B2 to be
advanced so as to bring the appropriate pin p3 beneath the spring pin p¹ of the
key used for designating "T," and cause the rod L' to be lifted so as to bring the
lower type wheel into printing position in front of the presser bar P. Then, while
the said bar B still remains down, he will depress with bis other hand, the key
representing "T" which will cause the bent end of the appropriate lever K 2 to.
project from the dial the corresponding dial pin; the lever F to operate upon the
swinging lever F2 and cause, first, the presser-bar to make a dead stroke towards.
the type wheel; secondly, the vertically swinging arin a 2 to depress the dial pin
representing the space on the type wheel and disengage from said pin the laterally
swinging arm a; and thirdly, the ends me of the arms m' to engage with the
teeth of the locking wheel E and hold the type wheels and type wheel shaft firmly
from rotation and cause the bar B 3 to be depressed, so as to effect through the
intervening devices, the engagement of the appropriate number of quads by the
three pawls V, V, V. All this takes place upon the depression of the key used to
designate "T." When then the said key is released and permitted to rise, the
bar B3 will resume its normal position and in so doing will cause the three.
pawls V, V, V, to withdraw the appropriate number of quads from the path of the
projection C 3 and permit the piece or bracket M 2 to advance until said projection C 3.
strikes the next quad in its path. The single pawl V' on this first stroke will.
perform no function but will be ready to act, at the next stroke upon the quads just.
set up.
The pin 4 on the end of lever F¹ in passing through the upper portion of cam ƒ¹.

page_text: will cause the lever F2 to recede and remove the presser bar P with the paper
from
contact with the type wheel and at the same time through the rod G and link J,
raise the end of bell crank lever G¹ from off sleeve a 4 thus allowing the ends ma
of the rods m to be receded or disengaged from locking wheel M and thus permit
the type wheels and shaft to rotate till the arm a engages with the shoulder e 2 of
the dial pin just set up by the designation of the letter "T," this operation
bringing the letter T on the lower type wheel to the printing point; and the key K2
will also fall back to normal position.
"
When the next letter "h is designated, the preceding letter T will be printed,
the paper carriage advanced by the withdrawal of the quads from in front of the
projection N¹ a distance corresponding to the width of the letter T just printed and
the letter "h" on the upper wheel will be brought to the printing point, and so in
like manner will the designation and printing of the letter "e" take place.
When the letter "h" is designated by the striking of its appropriate key, the
movement of the lever F consequent thereon will, through the rod cause the pin
wheel to be rotated and the bell crank lever h to be vibrated thereby releasing
the pin i and permitting the rod L' and its connections to descend. Such release
of the rod of course takes place in point of time after the impression has been
made of the letter T.
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 :-

a primary spring for rotating said carrier,. a paper carriage and supplemental
springs for keeping the primary spring under tension and for operating the paper
carriage, substantially as described.
2. In a type writing machine in which the type carrier is rotated to position the
character in one operation, and the character printed in the succeeding operation
by the key operated to position a second character, spacing mechanism for the
paper carriage comprising a series of quads normally obstructing the travel of the
carriage and means operated by the keys for withdrawing said quads singly or in
series froin the line of obstruction whereby a variable letter space movement is
imparted to the carriage, substantially as described.
