Improvements in Type Writing Machines.
I, RICHARD WILLIAM UHLIG, of College Point in the county of Queens and
State of 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:
This invention relates to an improvement in Type Writing Machines, and more
particularly to such as employ a revoluble type carrier.
The object of the present invention is to improve and simplify the construc-
tion and arrangement of various parts of the machine; to enhance its accuracy
of operation and its efficiency and to reduce the cost of production to a minimum
without detracting from its capability to accurately and effectually perform all
the functions of a modern type writing machine.
A further object is to provide efficient means whereby to lock the type carrier
in writing position.
A further object is to construct and arrange the flyer of the machine that its
cooperation with the key levers will effect a stop for the type carrier and also
lock the latter against rotation in either direction after it shall have been moved
to writing position.
A further object is to provide efficient means for returning the type carrier and
cooperating parts to normal position when a key lever shall have been released.
A further object is to provide simple and efficient means whereby to lock the
type wheel in normal position.
A further object is to so arrange the radiating key levers and finger buttons or
keys that the letters or characters on the latter shall be disposed parallel with
each other and at right angles to the operator, without the necessity of bending
or twisting the key levers.
A further object is to improve and simplify the hammer mechanism of a type
wheel machine.
A further object is to provide simple means whereby to adjust the stroke of the
hammer.
A further object is to provide a simple and efficient hammer stop.
A further object is to provide simple means for compensating for wear in the
gearing.
A further object is to provide the machine with a simple and efficient ribbon
feed mechanism.
A further object is to provide the machine with simple indicating devices.
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.

page_text: view of the universal bar; Figures 7 and 8 are cross sectional views; Figures, 9,
10, 11, 12, 13, 14, 15, 16, 17 18, 19, 20, 21 and 22 are views of various other
details; and figures 23, 24 and 25 illustrate modifications.
A represents the frame of the machine, comprising a tapering body portion 1
and a rear elongated portion 2 disposed at right angles to the body portion 1
for the reception of the carriage, which is mounted thereon in a manner hereinafter
described in detail. The inner or forward smaller end of the body portion 1 of
the frame is made with a transverse web or bar 3 so curved as to make one-third
of a circle concentric with the journal of the flyer hereinafter described. The
curved bar or web 3 projects above the upper face of the part 1 of the frame so
as to form a segmental flange 4 which is made with a number of notches for the
reception and guidance of the key levers 5. The key levers 5 are also disposed
in convergent slots or grooves 6 made in the upper face of part 1 of the frame in
line with the notches or flange 4. The upper face of part 1 of the frame is also
made with three segmental grooves a, b, c, at least one wall of each of which is
made inclined whereby to form contracted bottoms to said grooves in which the
pivot pins or trunnions d of the key levers have their bearing. The key levers
are so arranged that the bank of keys will be rectangular in form and said bank
may be said to be divided into three (more or less) sets or rows of keys with key
levers of varying lengths. The trunnions of the shortest key levers are mounted
in the groove a; the trunnions of the longest key levers are arranged in the
groove 6 and the trunnions of the key levers of intermediate length are disposed
in the intermediate groove c. The key levers are provided with buttons or keys 7
and it is very desirable that the letters and characters on these buttons or keys
be disposed at right angles to the writer but it would be undesirable to bent or
twist the key levers for this purpose. In order, therefore, to dispose the buttons
or keys so that the letters and characters of each row shall be parallel with each
other or at right angles to the operator, each button or key is provided on its under
face with an enlargement 8 and each enlargement is made with a socket 9 for
the reception of the end of a key lever, said sockets being disposed at a greater
or less angle to the letter or character according to the key lever on which the
buttons or keys are placed, the relative angle of the letters or characters and sockets
of the buttons or keys at the ends of the bank being greater than those of the inter-
mediate buttons or keys and the angle of the sockets relatively to the letters or
characters gradually decreasing toward the center of the bank or key board.
Each key lever is provided at its forward end with a depending enlargement 10
having a slightly inclined curved cam edge 11. The key lever thus constructed is
intended to cooperate with the type wheel moving mechanism presently to be
described and by the form of cam end of the key levers I am enabled to gain force
at the first part of the stroke of a key lever to lighten the touch. The key levers
are preferably fulcrumed between their ends as above described, but they may
be pivoted at their rear ends and the buttons or keys 13 secured thereto between
the ends thereof; in which case the cam enlargement 14 will be reversed as shown
in figure 24.
A plate i is secured to the frame of the machine over the key levers and pro-
vided at one edge with a number of integral spring fingers i¹ which bear upon the
key levers, whereby to return the latter to their normal positions. The plate i
also serves to prevent the displacement of said key levers. In order to cushion
the key levers so as to prevent noise when they return to their normal position,
a cordis laced through the notches of the segmental flange 4 so as to be seated
in the bottoms of said notches and receive the key levers when the fall.
A post 15 is disposed on the intermediate portion of the frame concentric with
the segmental flange 4 and on this post, a pinion 16 is loosely mounted. The
intermediate portion of the frame is provided at each side of the center and in line
with the post 15, with posts 17 in each of which a shaft 18 is mounted. Arms
or levers 19 are secured to the respective shafts 18 and project inwardly toward
each other, the free ends of said arms or levers being provided with rack bars 20

page_text: disposed practically at right angles thereto and meshing with the pinion 16.
Each arm or lever 19 is provided with a diagonal arm 21 and said arms project
toward each other in proximity to the cam ends of the key levers, terminating
normally close to each other in line with the longitudinal axis of the machine.
Each arm 21 is provided at its respective ends with lugs or ears 22 which con-
stitute bearings for the journals of an antifriction roller 23. The cam ends of
the key levers cooperate with the antifriction rollers 23 to move the levers 19 and
transmit motion to the pinion 16. Instead of providing the levers 19 with the
rollers 23, the arms 21 of said levers may be made in the forms of cams and
the cams at the ends of the key levers displaced by anti-friction balls 24 (or rollers)
as shown in figure 25.
The segmental racks or toothed segments 26-27 are mounted loosely on the
post 15 and the segment 29 is secured to the pinion 16 so as to rotate therewith.
Both tooth segments mesh with an elongated pinion 28 (which is preferably in
the form of a cage wheel) so that they both move together and are mounted on
balls 29, the latter having bearings in a groove or pocket in the frame. The
elongated pinion 28 is made with a tubular extension or sleeve 29 on which the
type wheel or carrier 30 is mounted and adapted to rest on an annular flange 31
on said sleeve, to which flange, the type carrier is secured by means of a pin so
as to cause it to rotate with the elongated pinion and its tubular extension. The
pinion 28 (with its tubular extension 29) is mounted to rotate on a post 31ª pro-
jecting upwardly from the framework, having bearing against said post only at
the upper extremity of the sleeve 29 (as at 32) and at the lower extremity of the
pinion 28 (as at 33), so as to reduce the friction to a minimum.
The type wheel is made hollow and provided with internal flanges 34, 35 at its
top and bottom so as to form a partial hub for the wheel. The type wheel is also
rounded internally as at 35° at the juncture of the top and bottom with the cir-
cumferential wall of the wheel whereby to strengthen the same.
From the construction and arrangement of parts above described, it will be
seen that when a key lever is depressed the levers 19 will be moved and transmit
motion to the pinion 16. The segment 27 being secured to the pinion 16, motion
will be imparted by it to the elongated type wheel pinion 28 and set the type
wheel in accordance with key lever which has been depressed. The motion thus
imparted to the elongated pinion 28 will be transmitted by the latter to the
loose segment 26. The segments are located, one upon the other, so that the
teeth of the two segments will be coincident. There may of course, be more or less
wear between the teeth of the segments and the elongated pinion and in order
to compensate for or correct such wear, the two segments are adjustably connected
together. For this purpose, one of the segments is made with an elongated
slot 36 and a screw 37 is passed through this slot and made to enter a screw
threaded hole in the other segment, the head of the screw bearing against the face
of the segment having the slot therein.
The upper segment 26 is made with an arm 38 which projects over the arm 21
of the wheel moving levers 19, said arm 38 terminating in a flyer 39 comprising
two arms 40 curved in opposite directions and marking, approximately, a circle.
The flyer 39 is slit, as at 41, to permit the arms 40 to have a slight spring action
and also to facilitate the adjustment of said arms 40 relatively to each other. The
free ends of the flyer arms 40 are beveled to insure the entrance of the key levers
and the latter are made with upper beveled edges 42 to cooperate with the beveled
ends of the arms 40. The under segment 27 is also provided with an arm which
constitutes another flyer 43 disposed under and parallel with the upper flyer and
terminating in a finger 44 immediately under and between the free ends of the
arms 40 of the upper flyer 39. With such construction; when a key lever is de-
pressed, the gearing will be moved as above explained and the two flyers will be
moved laterally in the segment of a circle until the key lever which has been
operated is reached, when the beveled edge 42 of the key lever will enter between
the finger of the lower flyer and one of the arms of the upper flyer and thus the

page_text: further movement of the flyers and the gearing will be stopped and the type
wheel will be set with the desired letter or character in writing position.
It will be observed that the entrance of a key lever between the flyers as above
explained, not only serves to stop the type wheel at the proper letter, but that it
also serves to lock the type wheel against retrograde movement and thus the
type will be effectually locked against movement in either direction until the key
lever shall have been released by the operator. The type wheel will, therefore,
be held rigidly in writing position until the impression shall have been made
and there will not be the slightest danger of inaccurate alignment in the writing
on account of lost motion, the auxiliary flyer 39 serving to take up all wear and
lost motion.
In order to simply and quickly calculate and determine the spaces upon the
type carrier in the manufacture of the type carrier and those parts which connect
it with the key lever ends, the following method has been found efficacious.
Figure 13 shows a portion of the frame of the machine and on this figure, two
lines are shown converging from an imaginary point f. These lines repre-
sent the positions of the key levers of letters Q and P which are located at the
respective ends of the series of key levers. It is of course understood that the
key levers do not extend to the point of but end as indicated at gg. The point f
is merely an arbitrary one, from which to regulate the slotting of the frame for
the key levers. It will be observed that the lines of the key levers are crossed
by a curved line hand this line represents that point of the flyer which engages
the lever ends. The type pinion is one-half inch in pitch diameter and the pitch
diameter of the toothed segments of the flyers is one and one-half inches. It will be
notiched that by moving the flyers a distance equal to a part of a circle, the type
wheel pinion (and consequently the type wheel) will be caused to make one com-
plete revolution. In order to obtain this result I use the one-third circle for the
purpose mentioned. The segment of a circle is only an imaginary line, since it
merely indicates the path of movement of the flyer. The whole of this arrange-
ment has its use chiefly in that errors in manufacture can be readily detected
without any great mechanical calculation.
A curved universal bar 45 is disposed over the forward ends of the key levers
within the segmental flange 4 and concentric with the latter. The universal
bar 45 is provided centrally between its ends with a pin 46 which projects through
one of the notches of the segmental flange 4 and serves to guide said bar in its
vertical movements. The free ends of the universal bar are made to form inclined
shoulders 47 adapted to engage the wheel moving levers 19 and assist in returning
the latter to their normal position and then holding them in their normal positions.
Thus, when one of the levers 19 is moved forward by the depression of a key
lever at one side of the center of the key board, the other lever 19 (being in con-
tant gear with the pinion 16), will be moved inwardly and when the universal
bar is permitted to fall to its normal position, one of the inclined shoulders 47
will engage the lever 19 which has been moved inwardly and force it back to
its normal position. Both levers 19 being geared with the same pinion 16 the
forwardly moved lever 19 will also be returned to its normal position and the type
wheel will be brought back to starting point.
The universal bar is also provided with two arms 48 which project toward each
other and terminate a short distance apart at each side of the flyer 45, so that
when the universal bar and flyer return to their normal positions, the flyer and
parts connected therewith will be prevented from vibrating; the flyer being
stopped by engagement with one or the other of the arms 48 on the universal bar.
From points at or near the ends of the universal bar bars or arms 48ª depend
through the frame and are provided at their lower ends with holes 49 into which
pins 51 at the end of a universal frame 52 project.
The universal frame 52 is made with parallel bars 54 which are pivotally sup-
ported at their rear ends on adjustable arbors 55 mounted in brackets 56 secured
to the frame of the machine.

page_text: To the parallel bars 54 at points a short distance inwardly removed from their
pivotal supports arms-57 are secured and made to project upwardly so as to ter-
iminate in proximity to the wheel moving levers 19 said arms being bent at
their upper ends, so as to engage depending pins 57b on the wheel movers.
Springs 58 may be connected to the flyer segments and to the wheel movers
for assisting in returning the parts to their normal positions. The free ends of
the arms 57 normally bear against the pins 57b on levers 19, but when a key lever
is operated and the universal bar raised, the movement transmitted to the universal
frame 52 and the parallel bars 54 will cause the free ends of said arms 57 to move
away from the levers 19. When the key lever shall have been released and the
universal bar and cooperating parts permitted to return to their normal positions,
the arms 57 will be moved toward the levers 19 and one of said arms engaging
the pin on the lever 19 which had been moved rearwardly, will assist in forcing
said lever to its normal position, the other arm 57 meeting the other lever 19 when
it arrives at normal position and preventing it from being moved too far, said
arms 57 thus serving not only to return the parts but also retain them in their
normal positions.
If desired springs 58" may be attached at one end to the armis 57 and at their
other ends to the frame of the machine for assisting in returning the parts to
their normal positions. Or, if desired, the arms 21 of the levers 19 may be
connected by a spring 59. Or, a bent spring 60 may be used and made to bear
against the respective levers 19. If desired, all the devices above described for
returning the parts to normal position, may be employed on the same machine,
and used in conjunction with the weighted parts connected with the universal
bar.
In addition to the use of the auxiliary flyer 39 for holding the type wheel in
writing position, I prefer to also employ a positive lock. To this end, a star wheel 61
is secured to the lower end of the elongated pinion 28 and with this star wheel,
a dog 62 is adapted to engage each time a key lever is operated and thus lock the
wheel in the position to which it may be moved. The dog 62 is pivotally sup-
ported in the frame of the machine and guided in its movements by two guide
arms or plates 63, 63 secured to the machine frame at the respective sides of said
dog. Two bent arms 64, 64, are secured to the dog 61 and project upwardly
therefrom at the respective sides thereof and terminate within the path of move-
ment of the arms 57 so that when the universal bar is raised by the operation
of a key lever and the pivoted universal frame 52 is turned on its fulcrum by the
raising of the universal bar, the upper ends of the arms 57 will be moved rear-
wardly and engaging the arms 64, will move the same and thus cause the dog 62
to be turned on its fulcrum and engage the star wheel 61, thereby positively
locking the type wheel or carrier in writing position. When the key lever
which has been operated, is released so as to permit the return of the universal
bar and universal frame the arms 57 will be also returned to their normal positions
and the dog 62 will be moved out of engagement with the star wheel 61 by means
of a spring 65, thus permitting the type carrier to return to its normal position.
I have herein before described how the type carrier is returned to and retained in
its normal position by the action of the shoulders at the ends of the universal
bar and by means of the arms 57 on the universal frame but to further insure
the return to and retention of the type carrier at normal position, the devices
now to be explained may be employed. Each vertical shaft 18 is extended some-
what below the respective tubular posts 17 and to the lower end of each shaft an
arm or lever 66 is rigidly secured. The arms or levers 66 project diagonally in
reverse direction so that their free ends terminate approximately at a common
point centrally under the frame of the machine and normally bear or rest against
a shoulder 67 on a beveled block 68 which projects from the universal frame 52.
Thus the type wheel actuating devices will be normally locked.
For this construction and arrangement of parts, it will be seen that when a key
lever is depressed, the type wheel actuating mechanism will be moved as above

page_text: described and the type wheel set for the letter corresponding to said key lever
and simultaneously, the universal bar 45 will be raised, thus raising the universal
frame 52 and moving the shoulder 67 on block 68, out of line with the free ends
of arms or levers 66 so as to permit the operation of the key wheel actuating
mechanism. The operation of the gearing will cause the shafts 18 to turn in
opposite directions and consequently the arms or levers 66 will be moved in reverse
directions. Now, when the key lever which had been depressed, is released, the
universal frame 52 will be permitted to descend, whereupon the beveled block 68
(being carried down by the universal frame) will press against one of the arms
or levers 66 and move it to its normal position. The other arm or lever 66 will
be positively returned to its normal position by means of bent pins 69 secured to
the universal frame 52, one of such pins being provided for each lever 66. Motion
will thus be imparted to one of the rack bars of the gearing through the inter-
mediate connections and the return of the type wheel and the arm or lever 19
which had been actuated, to their normal positions, will be effected. The other
rack bar will, at the same time be actuated by the pinion 16 and the other lever 19
and the other arm or lever 66 will thus be returned to their normal positions.
The universal frame 52 is provided at its pivoted end with an arm 70.
Arbors 71
are adjustably secured to the brackets 56 and between these arbors, the yoke 72
of a hammer 73 is pivotally supported. The pivoted end of the yoke 72 is con-
nected by a cross bar 74 having a lug 75 between its ends. A bent arm or bar 75"
is pivotally attached at one end to the lug 75 and at its other end is attached to
the arm 70 of universal frame 52 by means of a movable connection. By this
construction, the movement of the universal frame 52 on its fulcrum will cause
the arm 70 to first move freely a short distance and then pull the arm or bar 75"
whereby to impart a sudden movement of the hammer and result in a quick blow
of said hammer against the paper and ribbon passing in front of the type wheel.
In order to lighten the hammer, a spring 77 is attached at one end thereto and at
the other end to the frame of the machine.
While
From the construction and arrangement of hammer mechanism above described,
it will be seen that the hammer is operated positively by the key lever and inter-
mediate connections without the intervention of springs; thus simplifying the
construction and also rendering it possible to regulate the blow of the hammer,
to some extent, by the pressure applied by the operator to the key levers.
stops for hammer are not absolutely essential, still I prefer to provide such stops.
To this end, the hammer arm is provided with two fingers or projections 78-79,
the former being provided with a rubber head 80 adapted to strike the frame and
cushion as well as limit the return or backward movement of the hammer.
projection 79 is screw threaded for the reception of an adjustable head 81 (pre-
ferably of rubber), adapted to strike the rear end of the frame. By adjusting the
head $1 the degrees of force with which the hammer strikes the paper passing in
front of the type wheel, can be regulated and thus the hammer can be set for
manifolding purposes or for a single sheet of paper. When not manifolding, the
hammer can be thrown by giving a quick blow on keys.
The
It will be observed that the fulcrum of the hammer is quite close to the point
where the hammer operating device engages is to that a short movement of said
operating device (the universal frame) will effect the complate and quick throw
of the hammer.
The elongated portion of the frame is provided with two guide plates 82 for
the carriage B. The carriage comprises two parts 83-84 hinged together by
means of a rod 85. The lower part 83 of the carriage is made in its longitudinal
edges with grooves 86 into which the edges of the guide plates project, the latter
being provided with anti-friction rollers or collars 87 on which the carriage runs.
The upper part of the carriage normally rests upon the lower part but can be
raised slightly to permit the operator to more easily see the last line of writing.
The two parts of the carriage are normally locked together. For this purpose,
the upper part 84 of the carriage is provided at its respective ends with depending

page_text: ears SS, each provided with an elongated slot larger at one end (89) than at the
other end (90) and through these slots and the end bars of the lower part 83 of
the carriage, a longitudinally movable rod or bar 91 extends said bar projecting
beyond its bearings to form a thumb piece 92 at one end and to bear against a
spring 93 at the other end, which spring is secured at one end of the lower part 83
of the carriage and serves to maintain the rod or bar 91 in the larger end of the
slots in the ears 88 and thus lock the two parts of the carriage together. The rod
or bar 91 is contracted in proximity to its ends as at 94, 95, so that when it is
pushed longitudinally, these contracted portions will align with the smaller
ends 90 of the slots in the cars 88 and thus permit the upper part of the carriage
to be raised. When the part 84 of the carriage is again lowered and the rod or
bar released the springs 93 will force the latter to its normal position and effect
the lock between the two parts of the carriage as above explained.
The carriage will be limited in its longitudinal movement in both directions
by the engagement of a projection 96 thereon with pins or screws 97, 98 at the
respective ends of the elongated portion of the frame.
A ratchet bar 99 is secured to the bottom of the part 83 of the carriage and
constitutes part of the carriage feed mechanism. A lever 100 is pivotally sup-
ported between its ends in the frame of the machine and is provided at one end
with a head 101 from which a fixed dog 102 projects and adapted to engage the
ratchet bar 99. The head 101 also carries a pivoted dog 103 (and suitable stops
and a spring therefor), adapted to cooperate with the fixed dog and the ratchet
bar in effecting the feed of the carriage. From its pivotal support, the lever 100
projects inwardly toward the front of the machine and is maintained in its normal
position by means of a spring 104 secured at one end thereto and bearing at its
other end against the bottom of the machine frame or more properly speaking,
against a roller 76 mounted therein. The inwardly projecting arm 105 of the
lever 100 extends over the universal frame 52 so that when said frame is raised
by the elevation of the universal bar 45 upon the operation of a key lever, the said
lever 100 will be turned on its fulcrum and operate the ratchet carriage feed
mechanism. In order to effect the operation of said ratchet feed for spacing
between words without affecting the writing or hammer devices, a key lever 106
is located in the center of the machine but does not extend to the universal bar.
The key lever 106 is provided at its inner end with a large key or button 107
and to its outer or forward end, one end of a rod 108 is attached, the other end of
said rod being connected to the arm 105 of the lever 100. Thus, when the space
key 107 is depressed the ratchet feed mechanism will be actuated to permit the
carriage to move one tooth. In order to regulate the tension of the key levers,
a spring 109 is employed, one end of said spring being connected with the pin 46
of the universal bar 45 by means of a link 110 and the other end of said spring
being connected with an adjusting screw 111 in the bottom of the machine frame.
A key lever 112 is pivotally supported between its ends to a lug or projection
depending from the bottom of the machine frame. One arm of this key lever
terminates under the free end of arm 105 of the lever 100 and the other arm
projects through a yoke 113 depending from the front of the frame and terminates
under the spacing key 107 where it is provided with a key or button 114. The
lever 112 is maintained in and returned to its normal position by means of a
spring 115. By means of the key lever 112, the dogs 102, 103 can be moved
entirely out of engagement with the ratchet bar 99 of the carriage feed mechanism
and thus release said carriage and permit it to be moved back or forth at the
will of the operator.
In order to propel the carriage from right to left of the machine when the
ratchet feed mechanism is operated, a spring drum 116 is attached to the machine
frame and provided with a peripheral groove in which a cord 117 is
wound, one end of said cord being secured to the drum and the
other end being secured to the carriage by means of an eye 118
to receive a pin projecting therefrom. The drum 116 is mounted on a stud 119

page_text: secured to the machine frame, said stud being provided with a hook 120 for the
reception of one end of the spring 121, the other end of said spring being attached
to the drum. To permit the passage of the hook 120 into the drum, one face of
the latter is notched, as at 122. The stud 119 also serves to support a bell 123,
the hammer 124 of which is carried by an arm 125 pivoted to the machine frame.
The arm 125 is maintained in and returned to normal position by means of a
spring 126 attached to said arm and machine frame respectively the movement of
the hammer 124 toward the bell being limited by means of a stop 127. A spring
pressed dog 128 is pivoted to the arm 125 in position to be actuated by a projec-
tion 129 on the carriage when the latter approaches the end of its forward travel.
It is desirable to provide a margin stop for the carriage. For this purpose the
rod 85 is provided at a point between its ends with a pin 130 and at one end with a
thumb piece 131 by means of which to turn the iod and bring the pin out of
line with a lug 132 projecting from a stop block 133 adjustably mounted on a
ratchet bar secured to the frame. The rod 85 will be returned to its normal
position when the thumb screw shall have been released by the operator, by means
of a spring 134 and thus the pin will be moved in line with the stop, in which
position it will be retained by means of a stop pin 135.
The pin 130 is beveled so that when the carriage feeds from right to left from
the starting point to the right of the lug 132 on stop block 133, said pin will ride
over said stop lug (turning the rod 85) and then be brought automatically to
its normal position by the spring 134.
An L-shaped arm 136 is mounted on the rod 85 at or near one end thereof.
The arm 136 is made at one end with a perforated boss for the accommodation
of the rod 85 and said boss is made with a slot 137 through which a spring dog 138
projects, said dog being adapted to enter one or anorger of a series of notches 139
and thus the L-shaped arm 136 is adjustably attached to the rod 85. The purpose
of the L-shaped arm 136 is to constitute a hammer lock, so as to prevent the
hammer from operating to cause an impression on the paper when the carriage
approaches the end of its forward movement. Thus when the carriage shall have
moved nearly to the end of its travel the arm 136 will become disposed over the
horizontal arm or yoke of said hammer and prevent the throw of the latter. About
the same time the hammer lock (L-shaped arm 136) reaches the hammer, the bell
hammer will be tripped and the bell sounded, so that by my improvements the
signal will be sounded and at about the same time the hammer will be locked.
Should it be desired to print a few letters after the hammer stop or lock reaches
the hammer, this can be accompanied by turning the rod 85 by means of the
thumb piece at one end thereof so as to move the L-shaped stop or lock arm 136
out of the path of the hammer.
The letters and characters are arranged on the type wheel in three rows as
usual in machines of this class, the small letters and some characters for punctua-
tion being arranged in the top row; the capital letters and other punctuating
characters in the next row and the figures in the next row. The type wheel is also
provided, below the bottom row with an underscoring character as shown at 140.
It is therefore necessary to move the type wheel and the elongated pinion which
operates it, upwardly either temporarily to permit the writing of a single letter or
character, or permanently when it is desired to write several letters or words in
capitals or a number of figures. To permit these results the devices now to be
described will be employed. Two grooves guides or rods 141 are secured to the
intermediate portion of the frame at each side of the elongated pinion 28 and
project both above and below the web of the frame. Through these guides, two
arms 142, projecting from a plate or bar 143, pass freely, the upper ends of said
arms being secured to the latterally projecting ends of a plate 144 disposed between
the upper end of the elongated pinion 28 and the annular flange 31 to which the
type wheel or carrier is secured. An anti-friction roller 145 is mounted in the
plate 144, on which roller, the annular flange 31 rides and thus provides a roller
bearing for the type wheel or carrier.

page_text: The plate
or bar 143 projects laterally in both directions from the arms 142
and at its ends are made with U-shaped or slotted arms 146, 147. To one side
of the main frame, two key levers 148, 149 are pivotally supported between their
ends on a single pivot pin, one of said key levers being provided with a key or
button 150 representing "capitals" and the other key lever being provided with
a key or button 151 representing figures. The key levers 148, 149 are maintained
in and returned to their normal positions by means of springs 152. Both key
levers 148, 149 are adapted to plat in the U-shaped or slotted arm 146 but they
will be limited in their movement by fingers 153, 154 which are adapted to
engage the underface of the frame when the key levers 148, 149 are depressed,
the fingers 153 on the lever 148 being shorter than the lever 154 on the lever 149,
whereby the lever 148 will be permitted to have a further movement than the
lever 149. From this construction and arrangement of parts it will be seen that
when one or the other key lever is depressed, the forward end thereof will engage
the end wall of the slotted or U-shaped arm 146 and thus move the plate 142
upwardly and raising the type wheel for a letter or character of the lower or inter-
mediate row on the type wheel, according to the key lever (148 or 149), which has
been depressed. When the key lever (148 or 149) shall have been released by the
operator, it will be returned to its normal position by means of the spring as
above explained: the plate 143 will be forced downwardly by a spring 155 and the
type wheel and elongated pinion will drop to their normal positions. It frequently
happens, as above intimated, thet it is desirable to set the type wheel permanently
or for a considerable time, as when one or more words are to be written with capital
letters or it is desired to write a number of figures. For this reason two additional
key levers 156, 157 are pivoted to the main frame at the opposite side thereof
from the key levers 148, 149 and are in all respects duplicates of the latter. The
forward ends of the key levers 156, 157 play within the slotted or U-shaped
arm 147 and cooperate with the same to effect the setting of the type wheel in
precisely the same manner as above explained in connection with the key levers 148
and 149. A small transverse shaft. 158 is mounted in suitable bearings in the
framework. Both ends of this shaft extend beyond the bearings and on one end,
an arm 159 having two teeth 160, 161, is secured and adapted to be engaged by
a pin or projection 162 on the slotted arm 147 of the plate or bar 143. To the
other end of the shaft 158, an arm 163 is secured and made to normally hear
against the outer face of the upper end of the slotted or U-shaped arm 147 by
means of a spring 164. Now when one of the key levers 156 or 157 is depressed,
the bar or plate 143, elongated pinion 28 and the type wheel will be raised in the
manner above explained, but the pin or projection 162 will engage one or the
other of the teeth 160, 161, of arm 159 and the parts, including the type wheel,
will thus be retained in an elevated position after the key lever shall have been
released, so as to permit continued use of capitals or figures, as the case may be.
It will be readily seen however, that when one of the key levers 148, or 149 is
depressed, the free end there of will engage the arm 163 and cause the shaft 158
to be turned sufficiently to move the toothed arm 159 out of the path of the pin
or projection 162 on the slotted or U-shaped arm 147. For this reason, the type
wheel will not be retained elevated when either lever 148, 149 is depressed, but
as the arm 163 is omitted from the end of the shaft adjacent to the
ends of the key levers 156, 157, the shaft will not be turned by the operating of
either lever 156 or 157, and consequently the locking arm 159 will be free to act
to retain the type wheel elevated in the position to which it may be raised by one
of the key levers 156, 157. It is apparent that the type wheel can be released
from its elevated position by a depression of either lever 148 or 149, the end of
the lever which has been depressed engaging the arm 163 and turning the shaft 158
so as to move the locking arm 159 away from the pin or projection 162 on the
arm 147 and thus release the bar 143 and permit the return of the type wheel to
its normal position.
Returning now to the carriage, the means for carrying and feeding the paper
B

page_text: will be described. Between the end plates 164, 165 of the upper part of the
carriage, a paper carrying roller 166 is mounted in elongated bearings and with
this paper carrying roller, a single rubber covered feed roller 167 cooperates to
effect the proper feeding of the paper. The roller 166 is intended to receive and
have wound thereon, the paper on which the writing is to be done but it acts also,
as above intimated, in cooperation with the roller 167 to feed the paper. The
roller 166 is normally forced toward the roller 167 by means of springs 168. A
rod or bar 169 is disposed behind the roller 166 and mounted in elongated slots
in the end plates of the carriage. To this rod or bar, a plate 170 is secured and
provided with a number of fingers 171 (some preferably longer than others, and
adapted to embrace the paper carrying roller 166 so as to terminate over and in
proximity to the feed roller 157. The straight edge 172 of the plate 170 is
disposed under the feed roller and serves to guide the paper to the paper carrying
rollers 166. The paper carrying roller is provided at one end with a knob 173,
and on the adjacent journal of the feed roller, a notched wheel 174 is secured. An
arm 175 is pivotally connected to the end plate 164 of the carriage and provided
between its ends with a tooth 176 to engage the notched wheel 175, into contact
with which it is forced by means of a spring 177 and the free end of said arm 175
is made with a thumb piece 178. At a point between its ends, the arm 175 is
provided with a projection having a pin 179 thereon to be engaged by the hooked?
end of a pivoted lever 180 whereby to retain the tooth 176 or arm 175 out of con-
tact with the notched wheel 174 when desired. By means of these devices the
paper can be brought accurately to line of writing. If a sheet of paper be inserted
into the machine and wound on the paper carrying roller at least once, and the
pivoted arm 175 be released so that the tooth will engage the notched wheel, the 2
paper can be adjusted accurately by turning the paper carrying roller by means
of the knob 173. In such cases the feed roller 167 will be held fixed either by
the engagement of the spring-pressed arm 175 therewith or by the finger of the
operator. Thus the paper can be easily, quickly and accurately adjusted by means
of the knob 173.
A

The wheel 174 is made with 10 notches, each representing a half line space on
the paper when the carrying roller 166 is turned, so that by means of the paper
feed devices above described, the paper can be fed (two notches of the notched
wheel for each line of writing), without the use of other line space feed mechanism,
and said devices also permit accurate half-line spacing when it is desired to do 3
fancy or tabulated work. I prefer, however to also provide separate means for
accomplishing the line feed of the paper and these means will now be explained.
An angular lever 181 is pivotally attached to the end plate 165 of the carriage
and provided at its upper extremity with a thumb piece 182. The
lower arm 183 of the lever 181 is enlarged and provided at one 4
end of said enlarged portion with a hook 184 to engage a journal of the
feed roller 167 whereby to limit the movement of said lever in one direction.
ratchet wheel 185 is secured to the journal of the freed roller and is adapted to
he actuated by a small ratchet bar 186 pivotally connected at one end to the
enlarged portion of the angular lever 181 and prevented from accidental escape 4
therefrom by means of a spring 187. The maximum movement of the lever 181
for effecting a movement of the rollers sufficient to move the paper for a double
space, is limited by a shoulder 188 on said lever. In order to adjust the lever 181
for a single space, it is simply necessary to place an obstruction to the throw of
said lever. For this purpose, an arm 189 is pivoted between its ends to the 5
lever 181. By moving this arm so that the end 190 thereof is in line with the
journal of the feed roller, the lever 181 can be moved only a sufficient extent to
permit the paper to be fed for a single line. The arm 189 is preferably provided
with a notch 191 into which a pin 192 projects whereby to limit the movements
thereof.
I will now explaon the ribbon carrying and feed mechanism: The shafts 18
are extended somewhat above the wheel moving levers 18, as at 193 and on these
5

page_text: projecting ends of the shafts, sleeves 194 are loosely mounted and adapted to
project through holes in the sheet metal cover 195 of the machine, said sleeves
being prevented from vertical movement by means of screws 196 inserted in the
upper ends 193 of the shafts 18. Each sleeve 194 is provided at its lower end
with a spur wheel 197 and the upper end 198 of each sleeve 194 is contracted to
form a shoulder 199. Ribbon reels 200 are located on the upper ends 198 of the
sleeves 194 (above the sheet metal cover 195) and adapted to rest
on the
shoulders 199. Each reel comprises two parallel plates and a hub and to the
latter, a hook m is secured to the reception of the end of the inking ribbon. In
order to prevent the rotation or vertical movement of the ribbon reels independently
of the sleeves 194, the upper parts 198 of the latter, ate split so as to cause the
parts thereof to tend to spring outwardly and hold the reels in place by friction.
A bracket 201 is loosely mounted on the central post 15 and in this bracket a
transverse shaft 202 is loosely mounted, said shaft carrying worms 203 at its
respective ends to mesh alternately with the respective spur wheels 197. In order
to move the bracket 201 and shaft 202 so as to cause one or the other worm to mesh
with its cooperating spur wheel whereby to cause the inking ribbon to be fed in
one direction or the other, a spring arm 204 is secured to the bracket 201 and
provided at its free end with a pin or knob 205 which projects through a hole 206
in the cover 195. A tooth 207 projects into the hole 206, to be engaged by the
pin or knob 205 whereby to retain the worm shaft in mesh with one or the other
of the spur wheels. A ratchet wheel 208 is secured to the worm shaft 202 and in
close proximity to said ratchet wheel a bell-crank-lever 209 is loosely mounted
on the worm shaft. The depending arm of the bell-crank lever 209 normally rests
against one of the arms 57 secured to the universal frame. To the other arm of.
said bell-crank-lever, a dog 210 is loosely pivoted and adapted to engage the
ratchet wheel 208. From this construction and arrangement of parts, it will be
seen that when motion is transmitted to the universal frame by the operation of
a key lever as hereinbefore explained, and the arms 57 are moved backwardly,
the engagement of one of said arms with the bell-crank lever will cause the latter.
to turn on its fulcrum and cause the dog 210 to turn the ratchet wheel 208 and
the worm shaft and thus transmit motion to one of the ribbon reels, whereby to
feed the inking ribbon.
In order to provide simple and efficient means whereby the paper will be
inserted into the machine straight and so that the paper can be properly adjusted
in the carriage for a particular line of writing, provide the cover 195 of the
carriage with pointers 211, 211, at opposite sides of the type carrier. It is evident that
by making both of these pointers project toward the edge of the paper or to a line ·
of writing, the paper will be properly in the carriage.
To denote the last letter printed on the paper an indicator such as an arrow 212
is made on the type wheel to show the normal position of rest of the type wheel.
The cover 195 of the machine is preferably provided with a curved slot 213
through a pin 214 on one of the flyers moves. By this means the operator can
readily see whether or not the flyers are operating properly.
