Improvements in Type-writing Machines.
I, JOHN JAY GREEN, of 300, Broadway, New York City, New York, United
States of America, Manufacturer, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:---
My invention relates to improvements in typewriting machines and more
particularly to such as are known in the art as "index wheel" machines, one
object of the invention being to minimize the number of constituent parts of a
typewriting machine and reduce the cost of manufacture without detracting
from the efficiency of the machine, but on the contrary enhance its capacity, ease
of manipulation and its effectual execution of the functions required of a modern
typewriting machine of the index wheel type.
With these objects in view the invention consists in certain novel features of
construction and combinations and arrangements of parts as hereinafter set forth
and pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan view of a typewriting
machine embodying my improvement. Figure 2 is a plan view with some parts
removed and other parts shown in section. Figure 3 is a similar view with
additional parts removed. Figure 4 is a side elevation. Figure 5 is a trans-
verse sectional view. Figure 6 is an end view of the carriage. Figure 7 is a
transverse sectional view of the carriage. Figure 8 is a detail view of devices
for locking the parts against operation when the carriage approaches the end of
its travel. Figures 9 and 10 are detail views showing the positioning and
locking devices for the type carrier. Figure 11 is an enlarged detail view of the
carriage ratchet feed device. Figure 12 is a detail view of a portion of the
locking device shown in Figure 8. Figures 13, 14 and 15 are views illustrating
certain other details of construction.
The main frame of the machine comprises a fixed base 1 made in a single
casting, and a top piece 2 supported by posts 3 and braced by brackets 4. The
base is mounted on suitable legs 5. The brackets 4 at the inner end of the
machine serve to support a pivoted frame 6, said frame having at its inner end,
upwardly projecting ears pivotally attached to said brackets. The pivoted
frame comprises a front bar 8, a rear bar 9 and parallel arms 10 spaced apart
and connecting the bars 8 and 9 at points between their inner ends and the
intermediate portion 11 of the rear bar 9 is curved rearwardly for a purpose
hereinafter to be explained. From the respective ends of the rear bar 9 of the
pivoted frame, arms 12, 12, project rearwardly and are secured to or made
integral with a track or rail 13 for the accommodation of the carriage 14. The
intermediate bar 15 of the carriage is provided with rollers 16 mounted to run
on the head of the rail 13 and also with notched lugs 17 to receive said rib and
prevent lateral play or displacement of the carriage. The inner bar 18 of the
carriage extends from end to end thereof and is disposed above the arms of the
pivoted frame. To the inner bar 18 a ratchet bar 19 having teeth on its
upper edge is secured. Two plates 20 are removably secured to the pivoted

page_text: frame and project at their rear edges partially over the ratchet bar 19 to prevent
vertical displacement of the carriage. To render the plates readily removable
without completely withdrawing the screws 21, they are provided with elongated
slots 22 through which said screws pass. The rear bar 23 of the carriage is
mounted in a slot 24 in the upper end of a post 25 disposed on the curved por-
tion 11 of the pivoted frame. By mounting the carriage as above explained,
its easy removal can be effected by loosening the screws 21, swinging the
plates 20 from under the heads of said screws and then lifting the carriage from
its bearings. A platen roller 26 is mounted at its ends in the ends of the carriage
and cooperate with various devices hereinafter to be described for effecting the
feed of the paper.
The pivoted frame is maintained normally in the position shown in Figures 4
and 5 by means of a spring (or springs) 27. The spring 27 is made in the form
of a hook or open loop and is secured at one end to one of the uprights of the
rigid frame at the inner end of the machine, the other end of said spring bearing
against the pivoted frame at a point below the fulcrum thereof.
"Two short posts 28, 29, project upwardly from the rigid base 1 near the rear
-portion thereof and between said posts, a carrier frame 30 is pivotally supported
rearwardly of its center. The rear end of the carrier frame is made with an
enlargement 31 which serves as a counterbalance for said frame and the parts
carried thereby. A rod or shaft 32 is rigidly secured to the carrier frame at a
point inwardly from the fulcrum of said frame and projects upwardly some dis-
tance. Surrounding the rod or shaft 32 throughout the greater portion of its
length is a brass sleeve or tube 33. A type wheel 34 (having three rows of
characters) is mounted on the brass sleeve 33 at the upper end thereof and below
said type wheel, an aluminum sleeve 35 is mounted to rotate with the brass sleeve
or bushing 38. An arm 36 projects outwardly from the upper end of the sleeve 33
and is connected with the type-wheel by means of a pin 37. The inner end of
the carrier frame 30 is made with a standard 38 which projects upwardly to a
point slightly above the plane of the type wheel and to the upper end of said
standard, an approximate horizontal arm 39 is pivotally connected. The free
end of the arm 39 is made with a notched lug 40 which serves as a sight to assist
the operator in locating the point of writing on the paper passing over the platen
roller and thus enable him to make corrections and insertions accurately. The
arm 39 is made near its free end with a perforated boss 41 into which a
thimble 42 is inserted and into the lower portion of said thimble, the upper
end of the rod or shaft 32 projects. The upper portion of the bore of the
thimble is threaded for the reception of a small screw 43 which normally bears
at its lower end against the upper end of said rod or shaft.
From the arrangement of parts above described, it will be seen that the shaft
on which the type wheel is mounted, is supported at both ends and that when the
carrier frame 30 is moved to throw type wheel against the paper, said supports
will move in unison and thus prevent all possibility of strain on the shaft 32 and
in this way insure the accurate operation of printing devices.
An aluminum wheel 44 is made integral with the lower end of the aluminum
sleeve 35 and provided in its periphery with a groove 45 for the accommodation
of a cord or chain 46. A toothed ring 47 is secured to the under face of the
wheel 44 and depends therefrom, said wheel having ten large teeth and each
tooth is made with beveled edges, the adjacent edges of two teeth cooperating
to form inverted V-shaped notches. The wheel 44 is maintained in and re-
turned to its normal position by means of a convolute spring 48 and said wheel 44
is operated and controlled for the purpose of rotating the type wheel to position
the characters thereon, by means of devices, the details of which will now be
explained.
In front of the framework, a series of key bars 49 is disposed, each provided
with a series of character keys or buttons 50. I prefer to employ three key
bars 49 and to secure ten character keys or buttons 50 to each key bar. Each

page_text: key bar is provided with an arm 51 which projects over the base frame 1 and
pivotally supported near its end to a lug 52 on said base. The base 1 is pro-
vided with lugs 53 disposed alongside the arms 51 to prevent lateral displace-
ment of the same and of the key bars. In rear of each arm 51 the base 1 is
made with a hole 54 and in rear of said hole a lug depends from the under face
of the base as best shown in Figure 15. One end of a spring 55 is passed through
the hole 54 and is made with a perforation to receive the lug. The other end of
each spring is located under and exerts an upward pressure against the arm 5.1
of one of the key bars for the purpose of holding said key bars in and returning
them to their normal position after having been depressed.
Levers 56, 57 and 58 are pivotally supported between their ends by means of
lugs located near the inner edge of the base 1 and are prevented from lateral
displacement by means of lugs 59 on said base. The inner ends of the levers 56,
57, 58, are secured respectively to the key bars 49 and at their other or rear
ends, they are provided with horizontal arms 60, 61 and 62 respectively, said
arms being preferably disposed in a line parallel with a horizontal line drawn
transversely through the shaft 32 on which the type wheel is mounted. Behind
the shaft 32, a fixed shaft 61ª is disposed and held between two lugs on the
pivoted carrier frame 30. Three sleeves 62ª are mounted loosely on the shaft 61ª
and from said sleeves, arms 63, 64, 65, project toward the front of the machine
and directly over the arms 60, 61, 62 of levers 56, 57, 58, so as to be actuated
by the latter. Springs 66 may be secured to the levers 56, 57, 58,
and adapted to act as a cushion between the arms thereon and the
arms 63, 64, 65. The free ends of the last mentioned arms are
bent inwardly and provided respectively, with dogs or enlargements 67, 68, 69,
disposed under the toothed wheel 47 and adapted to cooperate therewith for
positioning the type wheel. The type wheel is rotated by the movements of the
hand of the operator through the medium of the cord or chain 46. This cord or
chain is secured to and wound in the grooved periphery of the wheel 44 and
from said wheel, it passes over a pulley 70 mounted on the enlarged end of the
pivoted carrier frame 30; thence around a pulley 71, mounted on a pivoted
arm 72 and provided at its free end with a leather loop 73 for the reception of
the index finger of the operator. The loop 73 is preferably provided with a
movable ring or ferrule 74 for the purpose of adapting the loop to the finger of
the operator. The arm 72 above referred to is provided at one end with a fixed
sleeve 75 mounted loosely on a post projecting upwardly from the base I and
from the lower end of said sleeve, a short arm 76 projects as shown in Figure 13.
The short arm 76 is provided with a lug or tooth for the attachment of one
end of a spring 78, the other end of which is attached to the base 1.
The arm 72 is thus pivotally and yieldingly attached to the base and serves
to prevent undue strain on the cord or chain, the toothed wheel and the devices
cooperating with the latter. A spring plate 79 is secured to the free end of the
arm 72 and projects over the pulley 71 so as to retain the latter in place and
serve as a guide for the cord or chain 48. The free end of the spring plate 79
is made with a tit 80 to engage a notched boss 81 on the arm 72. A lug 82
is cast on the base 1 adjacent to the short arm 76 and through this lug, a liori-
zontal thumb screw passes, the free end of said screw abutting against a lug 83
on said arm 76. By these means the normal position of the arm 72 can be
readily adjusted. The inward throw of the pivoted arm 72 is limited by the
engagement of a lug 84 on the short arm 76 with the lug 82.
The operator will place the loop on his index finger and then move his finger
to desired character key. In performing these movements, the cord or chain 46
will be pulled and the grooved wheel rotated to move the type wheel to bring
the desired letter to or approximately to writing position. The operator will
now depress the key, and, assuming that it is one of the keys on the central
key bar, motion will be transmitted to the central lever 57 and the latter will
raise the arm and cause the dog or enlargement 68 at the free end thereof
:

page_text: to enter centrally between two teeth of the toothed ring 47 and become disposed
at the juncture of the adjacent edges of said two teeth. Should the operator
depress the key bar nearest the machine frame, the lever 56 will be operated and
the arm 63 raised so as to cause the dog or enlargement at the free end thereof
to enter a notch between two teeth and engage a beveled edge of one of the teeth
forming said notch, at a point between the ends of said beveled edge. The pres-
sure of the dog or enlargement 67 against the beveled edge of the tooth of the
ring will act to turn ring slightly further than it was moved by the cord or chain
to accurately position the type wheel for the desired letter. This additional
movement of the toothed wheel will continue while the dog or enlargement 67
is moving along the beveled edge of a tooth, the arrival of the dog or enlarge-
ment 67 at the angle formed by the juncture of the beveled edges of two adjacent
teeth insuring the proper positioning of the type wheel for the desired letter.
Should the operator depress the key bar farthest removed from the machine
frame, the operations would be similar to those just described, the toothed wheel
in this case being actuated through the medium of the lever 58, arm 65 and the
dog or enlargement 69 on said arm, the dog or enlargement engaging a beveled
edge of a tooth at the right hand side of the notch between two teeth instead of
at the left hand side as was the case with the dog or enlargement 67 on the arm 63
and thus the additional movement. imparted by engagement of the dog 69 with
the toothed wheel will be in a direction opposite to that imparted by the dog 67.
If the intermediate key bar is accurately operated, no additional movement
will be imparted to the type wheel but should the operator not pull the cord quite
far enough or slightly too far, the dog on the intermediate arm 64 will engage
the edge of a tooth at one side or the other of the notch formed by two teeth and
thus cause the wheel to have a slight additional movement to accurately position
the desired letter.
It will be noticed that the dogs 67, 68, 69 engage the toothed wheel at a point
some distance inwardly from the fulcrum of the carrier frame 30 so that after
the type wheel shall have been set for writing position, continued pressure on a
key bar will cause the carrier frame to be tilted and the type wheel to be thrown
toward the platen roller for the purpose of printing upon the paper passing over
said roller.
The inking ribbon 85 is attached to and moves with the platen carriage 14
and is supported and guided by means of devices which will now be described.
At respective ends of the carriage, plates 86 are loosely mounted between their
ends on the journals of the platen roller, one of which journals is mounted in
a hole in one end piece of the carriage and the other journal is mounted in an
open slot 87 in the other end piece of the carriage. The rear portion of each
plate 86 is made with an open slot 88, through which a screw 89 passes and
enters the carriage frame. The rear ends of the plates 86 are provided with
horizontal pintles 90 on which ribbon reels 91 are mounted and provided with
knobs 92 for turning them to run the ribbon from one reel to the other. Spring
tongues 93 bear against said reels and normally prevent them from turning and
also serve to prevent their displacement. The inner ends of the plates 86 are
bent laterally and then inwardly toward the front of the machine to form arms 94
and each of these arms is made with an open slot 95 having one wall beveled to
form a shoulder 96. The inking ribbon is guided through the slots 95 and be-
coming disposed under the shoulders 96, will be prevented from upward dis-
placement. By mounting the ribbon carriers as above explained, it will be seen
that they can be readily removed, together with the platen roller, by merely
loosening the screws 89 and it will also be seen that the connection of the
plates 86 with the carriage by means of the screws 89, displacement of the
platen roller will be effectually prevented.
Inking rollers 97 are mounted on the rear
respective sides of the space through which the
pose of keeping the ribbon supplied with ink.
bar 9 of the pivoted frame 6 at
type wheel passes. for the pur-
The ribbon will be made of a

page_text: length several times that of the carriage, the surplus being wound on one or the
other of the reels. When a section of the ribbon shall have become worn out
the operator will wind it on one of the reels and simultaneously unwind a fresh
section of ribbon from the other reel. The ribbon will be maintained normally
taut and away from the platen so that the writing will be always visible, by
means of a spring-actuated arm 98 carrying a roller 99 over which the ribbon
passes and by means of which the ribbon will be forced against the inking rollers.
The paper is conducted to the platen. roller by means of a sheet metal guide 100.
The guide plate is secured to the rear bar of the carriage by means of, tongues 101
and projects downwardly under the platen roller, terminating at a point some-
what beyond the axis of the roller, where it is provided with ears which con-
stitute bearings for a feed roller 102. The feed roller is pressed against the
platen roller by means of a spring 103 secured to the carriage and pressing up-
wardly against the sheet metal guide plate 100. To move the feed roller away
from the platen roller to permit the free adjustment of the paper, a lever 181
may be employed. The paper is pressed neatly against the platen reller at the
center by means of a V-shaped wire loop 104 having arms 105 secured to the
pivoted frame 6. The loop 104 partially embraces the platen roller and holds
the paper closely against the roller at the point of writing, the characters on
the type wheel passing through said loop when said wheel is thrown forward
during the operation of the machine.
For the purpose of feeding the paper, one end of the platen roller is provided
with a knob 105 and for the purpose of accurately regulating the line spaces,
a ratchet device now to be described will be employed. A spur wheel 106 is
secured to a journal of the platen roller and is adapted to be engaged by a
tooth or shoulder 107 on a spring 108. The rear end of the spring 108 is
provided with an arm or flange 109 attached to the carriage frame and said
arm or flange is made with a beveled end which rests on a shoulder or enlarge-
ment 110 on the carriage to insure the maintenance of proper tension on the
spring. When it is desired to move the paper without regard to the line
spacing, (as when a sheet is inserted for the purpose of making insertions or
corrections) the tooth or shoulder 107 should be moved out of contact with the
spur wheel. For this purpose, an arm 111 is loosely mounted on a journal of
the platen roller and is provided with a notch 112 for the reception of the tooth
or should 107, as shown in Figure 6. It is apparent that when the arm 111 is
moved toward the end of the spring, the shoulder at the lower end of the notch
in said arm will engage the beveled end of the tooth or shoulder 107 and cause
said tooth or shoulder to rise out of engagement with the spur wheel and its
free end to enter the notch 112, thus releasing the platen roller and permitting it
to be turned to feed the paper irrespective of the line spacing.
With the parts of the machine in their normal position as shown in the draw-
ings, the platen roller is in position to permit the printing of the lower case
characters which constitute the upper row of type on the type wheel. To permit
the printing of characters and figures of the two lower rows of type, the platen
roller must be lowered as is evident and for this purpose the appliances now to be
explained will be employed.
A sleeve 113 is loosely mounted between two lugs 114 projecting upwardly
from the base 1 near the rear end thereof and from said sleeve, a lever 115 pro-
jects toward the front of the base, said lever being provided at its front end with
an arm 116 which projects laterally beyond the machine base said arm being so
bent as to cause the outer portion 117 thereof to be disposed on a higher plane
than the inner portion and than the lever 115. The lever 115 is connected with
the pivoted frame 6 by means of a link 118 so that when said lever is depressed,
the pivoted frame carrying the platen roller will be lowered. To afford ready
adjustment for the pivoted frame 6 and to maintain it in such position as to
insure the maintenance of the accurate normal position of the platen roller for
lower case characters, the sleeve 113. is provided, with a rearwardly projecting

page_text: arm 119, through which a set screw 120 is passed and adapted to rest on the
base frame 1.
"
Two ears 121, project upwardly from the base 1, in rear of the arm 116 and to
one side of the lever 115. Between these ears, the ends of a shaft 122 are secured
and upon said shaft, two sleeves 123, 124, are loosely mounted. From the
respective sleeves 123, 124, key levers 125, 126, project, one of said levers being
provided with a key 127 indicating capital letters and the other lever being
provided with a key 128 indicating figures, the key 127 having the letters
cap" thereon and the key 128 having the letters "fig." The upward movement
of the key levers 125, 126, will be limited by the engagement of lugs 129 on
the sleeves with the ears 121. The two key levers 125, 126, project directly
over the elevated portion 117 of the arm 116 and the lever 125 is provided
between its ends with a lug 130 through which a vertically disposed screw 131
passes. The screw 131 is adapted to engage the upper end of a post 132 on
the base 1 for the purpose of limiting the downward movement of the pivoted
frame and platen roller when the key 127 is depressed and thus dispose the
platen roller in position for printing capitals. For printing figures the platen
must descend still further and for limiting the downward movement of the
pivoted frame G when the key 128 is depressed, a lug 133 on the pivoted frame 6
is adapted to engage an adjustable screw in the upper end of a post 134 on the
base 1.
Having described the construction and operation of the printing mechanism
and the devices which cooperate therewith, I will now proceed to explain the
manner of effecting and controlling the feed of the carriage.
A spring drum 135 is mounted on the rigid frame of the machine and around
this drum, a cord 136 is wound, the free knotted end of said cord being attached
to a notched arm 137 projecting from a plate 138 secured to the carriage.
A rocking bar 139 is disposed transversely on the pivoted frame and provided
on its under face near one end with a depending lug 140 to which the spacing
devices are connected. These comprise a plate 141 having ears 142 at one end
pivotally attached to the lug 140 on the rocking bar and provided at its other
end with a Hange 143, the outer end of which constitutes the fixed dog 144 to
engage the ratchet bar 19 on the carriage. A spring 145 is attached at one end
to a lug depending from the plate 141 and at its other end to the pivoted frame 6.
A plate 146 is pivoted at its inner end to the plate 141 and at its outer end it
is provided with a flange 147 which projects beyond the outer end of the plates
141 and 146 and is provided in its lower edge with a notch 148 the portion of
the flange beyond said notch forming a tooth 149 to engage the ratchet bar 19.
The plate 146 with its notched flange and tooth constitute the movable dog of
the ratchet feed devices. The plates 141 and 146 are connected together beyond
their pivotal connection by means of a spring 148. The flanges of the plates
141-146 are disposed between and guided by lugs 152 on the pivoted frame.
The rocking bar 139 is provided with an upwardly projecting arm 149 to
which one end of a rod or wire 150 is attached, the other end of said rod or
wire being connected with a stepped lever 151 disposed under the key levers
and adapted to be operated by the same when they are depressed.
When a key bar is depressed, motion will be transmitted through the lever 151
and rod 350 to the rocking bar 139, thus causing the latter to rock and force
the plates 141-146 forwardly. The result of these movements will be to cause
the fixed dog on the plate 141 to engage a tooth of the ratchet bar 19 and the
pivoted dog to move out of engagement with said ratchet bar. When the key
lever is released, the bar 139 will rock in the reverse direction and thus move
the fixed dog out of engagement with the ratchet bar and the pivoted dog into
engagement with a new tooth on said ratchet bar,-thus permitting the carriage
to feed a distance of one tooth.
An independent spacing lever 153 is disposed alongside the stepped lever 151
and the latter is made of such length as to be disposed under the finger key 154

page_text: on said spacing lever so that when the latter is depressed, motion will be imparted
through the devices above described to the ratchet feed mechanism for the pur-
pose of effecting the feed of the carriage for spaces between words. The spacing
lever 153 is carried by a sleeve 154" mounted between lugs on the base 1. The
sleeve 154 is provided with an arm 155 to which one end of a spring 156 is
attached, the other end of said spring being connected to an arm 157 on the
base I, for the purpose of returning the spacing lever. The upward movement
of the spacing lever is limited by the engagement of an arm 158 on the sleeve 154ª
with the base 1.
For the purpose of releasing the ratchet feed mechanism when it is desired to
move the carriage freely, I employ a rod or wire 159 disposed on the carriage
under the dogs of the ratchet mechanism. The ends of the rod or wire are bent
to form loops 160 which serve as handles and the free extremities of said rod
or wire are bent to form pintles 161 pivotally mounted in the ends of the
carriage.
In lieu of the bell usually employed for denoting the approach of the end of
travel of the carriage, I prefer to employ devices for positively locking the feed
mechanism of the carriage and these means will now be described. An arm 162
comprising a member 163 and a member 164 is pivotally attached at the juncture
of said members to the pivoted frame 6. A finger bar 168 made integral with
the member 164 projects therefrom and is provided at its free end with a finger
key 169. The free end of the member 164 of arm 162 is made with an upwardly
projecting tooth 165 and the free end of the member 163 terminates normally
to one side of a lug 166 depending from the rocking bar 139 in which position
it is retained by means of a spring 171. The plate 138 (hereinafter referred to)
attached to the carriage, is made with a series of two or more beveled teeth 167
and with a notch or recess 170. With this construction and arrangement of
parts, when the carriage approaches the end of its travel the tooth 165 at the
end of member 164 of arm 162 will ride upon the first beveled tooth 167 on the
plate 138 and thus cause said arm 162 to turn on its fulcrum and the free end
of the member 164 thereof to become disposed in line with the depending lug 166
on the rocking bar 139. This will lock the rocking bar against movement and
said rocking bar being actuated by the key bars through the medium of the
lever 151 and rod 150, these parts will also be locked, so that when the
member 163 of the arm 162 is in line with the lug 166, the keys as well as
the rocking bar will be locked and the further operation of the machine will be
positively prevented. Should it be desired however, to permit a few more letters,
this may be accomplished by moving the arm 162 by means of the finger bar 168
and permitting the carriage to move one tooth, when the tooth 165 on the
member 164 of said arm will become disposed between two teeth 167 on the
plate. The carriage can now feed several spaces and until the parts again
become locked by the engagement of the tooth 165 with the second tooth 167 on
plate 138. The parts may be again released in the manner above explained to
permit the insertion of additional letters, after which the tooth 165 will ride
into the notch 170 of plate 138 and the further feeding of the carriage will be
prevented.
It now remains to describe the manner of regulating the margin to be left at
the edge of the paper:
A horizontal bar 172 is mounted to slide through a transverse hole near the
base of the post 25 on the curved intermediate portion of the pivoted frame 6.
and said rod also passes through a perforated lug 173 to prevent possibility of
lateral displacement. A ratchet bar 174 (preferably of sheet metal) is provided
at its ends with ears or arms 175 loosely attached to the ends of the bar 172. An
elongated tooth 176 is provided on the post 25 and adapted to engage the ratchet
bar 174 to retain the latter at any desired adjustment and the ratchet bar is
maintained in contact with said tooth by means of a spring 177 secured to the
frame. One end of the ratchet bar is made with a shoulder 178 against which

page_text: the enlargement 110 on the carriage abuts to limit the return movement of the
latter and thus regulate the margin. One end of the ratchet bar is provided
with a thumb piece 179 by means of which to manipulate and adjust the same
and the backward movement of the ratchet bar may be limited by means of an
arm 180 fixed to the pivoted frame.
It will be observed that with my improved machine the writing is always clearly
visible; a small number of parts is employed as compared with other machines
of which I am aware, my improved machine comprising 150 separate pieces as
against 2000 constituting a machine of the Remington type; it is simple in
construction; easy to operate and it is accurate in the performance of its
functions.
Numerous slight changes might be made in the details of construction of my
invention without departing from the spirit thereof or limiting its scope and
hence I do not wish to limit myself to the precise details herein set forth.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a typewriting machine, the combination of printing devices, a carriage
and inking means mounted on the carriage.
2. In a typewriting machine, the combination of printing devices and a
carriage, a platen on the carriage reels mounted at respective ends of the carriage
and an inking ribbon wound on said reels and passing between the printing
devices and the platen.
3. In a typewriting machine, the combination of printing devices, a carriage,
