Improvements in Typewriting Machines.
A communication from abroad by WYCKOFF, SEAMANS & BENEDICT, of 327, Broad-
way, New York City, New York, United States of America, a corporation
organized under the laws of the State of New York.
I, JOHN CORRY FELL, of the Firm of Fell & James, of 1, Queen Victoria Street,
in the City of London, Chartered Patent Agents, do hereby declare the nature
of this invention and in what manner the same is to be performed to be parti-
cularly described and ascertained in and by the following statement; —
"
My invention relates to what is known as "line locking mechanism or means
for preventing the types from printing when the end of a predetermined line <r
amount of carriage travel has been reached, and has for its main objects to pro-
vide an efficient and desirable mechanism of this description. To these ends
my invention consists in the various features of construction and arrangement
and combinations of devices hereinafter more fully described and particularly
pointed out in the appended claims.

Referring now particularly to Figures 1 to 6 inclusive, 1 designates the paper
carriage which may be of any desired or suitable construction, and may be
mounted in any desired manner so as to travel back and forth in the usual way,
the movement of the carriage from right to left occuring step-by-step under the
influence of a spring drum or other motive power and controlled as customary
by suitable escapement or letter feeding mechanism. 2 represents the feed rack
connected to the paper carriage, 3 the spring drum by which the carriage is
drawn from right to left and 4 the spacing dogs adapted to properly co-operate
with the feed rack in the usual manner.
On the top plate 5 of the machine are arranged in a circular series the desired
number of type bar hangers 6, in each of which is pivoted at 7 a type bar 8,
bearing in this instance at its lower end an upper case type 9 and a lower case
type 10. The series or set of type bars when not in operation bear against the
type basket or rest 11, which is elliptical in form and is supported from the
top plate by depending arms 12. To the upper shorter crank arm of each type
bar or lever is attached one end of a connecting rod 13, whose lower end is
connected to its associated key lever 14, preferably through a turn buckle 15
and strap or loop 16, all of which is old in the said Remington No. 2 machine.
Other features of said machine are likewise shown in the drawings but since
they have not material connection with my improvements they need not be
specially referred to.
I shall now deal more particularly with my invention.
A short distance below the type basket or rest and axially of the type bar
system, stands normally a ring or wheel-like device 17, preferably elliptical in
configuration and preferably corresponding substantially in outline to that of
the type rest 11, but made of a smaller size. The shape of the type rest deter-
mines the form or disposition of the lower ends of the type bars when they are
in non-working position, that is to say, in this instance the type ends of the
bars when at rest are disposed in or describe an oval or elliptical figure. For
this reason in the said Remington machine the ring 17 is preferably made of a
shape or form corresponding to or approximating the figure or outline described
by the type ends of the type bars. Of course where the type bars are differently
disposed, the device 17 would preferably be differently shaped, and if the type
bars should not extend around to a complete ellipse or in a complete circle or
other continuous figure, it would not be necessary for the device 17 to be made
continuous or as a complete elliptical device or a complete circular device, etc.
Thus it will be understood that if for example the type bars were arranged in
a semi-circle or equivalent curve, as in well-known machines, it would be neces-
sary to make the device 17 likewise only semi-circular or of a substantially
similar curve.
The
purpose of the device 17 is to prevent the movement of the type bars to
the printing point or to the paper on the platen. when the carriage shall have
arrived at the end of its predetermined line (which, of course, may be varied)
and thus prevent one letter from printing upon or over another.
The said device 17 in the views under consideration is attached to the upper
end of a stem 18 which may be, though not necessarily, pivoted at 19 to the inner
end or longer arm of a lever 20, fulcrumed at 21 in a stand 22 attached to the

page_text: framework. To the rear or shorter arm of the lever 20 18 pivotany or
connected, as by hooks and-eyes, at 23, the lower end of an operating rod 24 which
at its upper end carries a cam piece 25, preferably pivoted at 26 to said rod. The
cam piece comprises an inclined or cam portion 27, a flat or horizontal. portion 28,
and a perforated lug 29, which enters between a pair of similar lugs 30 on the
uppermost end of the rod 24. The cam piece is formed with a jaw 31 and the
rod with a jaw. 32, and in the normal position of the cam piece these jaws are
maintained in contact by the pressure of a coiled spring 33 let into a seat in the
upper end of the operating rod and bearing at its upper end on that side of the
cam piece opposite the jaw 31. The upper end of the rod is forked or bifurcated
at 34 to enable the lug 35 on the cam piece to descend and the jaws to open
when the carriage is retracted, as will hereinafter appear.
The rod 24 is held up by a coiled spring 36 which spring, on account of its
angular attachment to the rod and to the top plate of the machine as shown,
also tends to draw and hold the said rod towards the right (considered from the
rear of the machine) and against a stop 37 which may be formed at the end of a
guide slot 38 made in the top plate. A pin 39 on the said rod strikes against the
top plate and limits the upward movement of said rod under the influence of
said spring.
The said operating rod 24 near its lower end is formed with a slot 40 in which
is located a pin 41, which projects rearwardly from the upper free end of an
arm 42 fastened to the rear end of a rock shaft or long pivot 43 supported in suit-
able stands 44 and 45, and provided at its front end with a key lever or arm 46.
As will be seen at Figures 2, 3 and 4, the lever 20 is preferably made so that the
shorter arm 47 is offset from the longer arm of said lever. This effect may be
best produced by making the lever in three separate parts, namely, the long arm,
the shorter arm, and a long laterally-arranged pivot connecting said arms
together.
The ring or device 17 may be covered or surrounded exteriorly with a soft or
yielding material, as felt, or soft rubber 48, to protect the types, and for the pur-
pose of guiding said device in substantially. a right line during its movements,
wires may be employed, and these may, be attached to the type rest and so bent
or shaped as to provide, within the device 17, the vertical guide fingers or
portions 49.
..
The carriage or some part attached thereto is provided with a device or a
plurality of devices for actuating the rod 24 and for causing it to vibrate the
lever 20 and move the ring or intercepting device 17 to a position where it will
be in the path of the type bars, and thus block them or obstruct their course of
travel towards the printing point.
Numerous devices for this purpose may be provided not only on the paper
carriage, but on some other part of the machine, as for instance the spring drum,
or other carriage propelling power, as will hereinafter be explained.
In Figures 1 to 6 inclusive the rod 24 is actuated by a pin 50 carried by the
carriage. Said pin projects rearwardly from a block 51 having a set screw 52
and adjustable lengthwise in a long slot 53 formed in a bar 54 attached by rigid,
integral side arms 55 to the carriage frame, and thus made directly a part
thereof. The purpose of making the pin 50 adjustable is of course to provide
for actuating the type bar intercepting ring or device 17 at any desired point
or time in the forward course of travel of the carriage from right to left,
and to aid the operator in adjusting said pin, the bar 54 may, if desired,
At Figure 61 have
be graduated to correspond with the usual carriage scales.
shown two such adjustable pins 50 whereby the type bars may be automatically
intercepted twice during one run of the carriage from right to left; and the
mechanism is such that the type bar intercepting means may be restored to
normal position after each such action, so that the carriage may proceed and
writing be done beyond both said actuating pins or devices to the full limit
of carriage travel provided by the construction of the machine. Instead of

page_text: having two adjustable actuators as shown in Figure 6, the carriage may hav
one adjustable and one fixed actuator as in Fig. 7.
The actuating pins 50 are arranged to travel in a horizontal plane which passe
through the inclined or cam portion 27 of the piece or head 25, so that in th
step-by-step movement of the carriage from right to left when said pin arrive
at the said cam portion 27 the cam piece, and the rod 24 of which it forms a
part, is forced or wedged down slightly by the pressure of said pin and unti
the latter comes upon the plane or table portion 28 of the cam piece, as showi
at Figure 3. By thus depressing the operating rod 24 the lever 20 is actuated
and the intercepting ring is pushed up into the path of vibration of the series
of type bars, as shown in dotted lines at Figure 1, so that none of said type bars
can be sufficiently vibrated to reach the printing point. As I have shown the
relative arrangement of the intercepting ring and the type bars, only a very
slight movement of the type bars may be obtained when the ring is in inter-
cepting position, but if the ring were smaller a greater movement of the type
bars might be had. I preferably construct the ring of a size or so arrange it as
that the type bars may have some movement at least before encountering the
intercepting device, for by so doing a yielding or more springy action is pro-
vided in case a key should be struck after the intercepting device is in operative
position, and which action is desirable because it relieves the type movement
and the escapement movement of strain and also produces less of a shock to or
reaction upon the muscles and nerves of the operator than is the case where the
line locking device comes suddenly into rigid and unyielding action.
If while the intercepting device is in working position (Figure 1 in dotted
lines and Figure 3 in full lines) it be desired to restore the said device to its
normal or non-working position in order to enable one or more letters to be
added to the line, the operator may depress the key lever 46 thus rocking the
shaft 43 and vibrating the arm 42 towards the left (viewed from the back of
the machine) and by reason of the connection between the crank arm 42 and
the rod 24 the latter is forced over towards the left and the cam piece is swung
away from and out of operative relation to the pin 50 on the carriage; and as
soon as this is accomplished the spring 36 operates to draw up the said rod and
through the lever mechanism pull down the intercepting ring, thus bringing
these parts to the dotted line positions shown at Figure 3, and with the cam
piece on the left-hand side of the pin 50, thus removing the intercepting ring
and enabling the writing to be proceeded with. If there should be a second
actuating pin this would of course act upon the type bar intercepting mechanism
in the same manner as that above described and if it should be desired to again
release the same or throw it back into normal position the release key 46 could
be operated as before.
After the release has been effected and the operating rod has been thereby
thrown to the left as shown in Figure 3 or to the non-operative side of the
pin 50, it will be brought to its normal vertical position against the stop 37
shown at Figure 2 by the spring 36 as soon as the carriage has advanced far
enough to permit this movement to occur.
On the return movement of the carriage for the beginning of a new line,
the said pin 50 will strike the vertical face or side 56 of the cam piece and cause
it to rock independently about its pivot 26, so as to enable the said pin 50
to pass by the said cam piece, and as soon as this has taken place the spring 33
will restore the cam piece to its normal position with the stop jaws 31 and 32
in contact.
The type bar intercepting mechanism is not constructed to also stop the car-
riage travel that is to say, when the parts are in the positions shown in full
lines at Figure 3 the carriage travel may be proceeded with by actuating the
space key, and also by operating the usual carriage release key which
disengages the escapement mechanism. In prior constructions where the line
locking mechanism is arranged so as to act upon some part of the escapement
usual

page_text: mechanism, the carriage travel is simultaneously arrested and the line locking
mechanism must be released or thrown out of engagement before even the space
keys can be operated to step the carriage down and if the carriage release key
should be actuated without first disengaging the line locking mechanism or
simultaneously disengaging it, the strap or band which connects the spring
drum with the carriage would form a loop and become disarranged if not broken
on account of the locked condition of the escapement mechanism and the inability
of the spring drum to rewind during the run down of the carriage. Of course,
in my construction there can be no feeding of the carriage through the agency
of the type bar key levers while the intercepting ring is in operative position.
But while I prefer not to positively stop the carriage travel as above explained,
this may be easily accomplished it will be seen by providing a lug as 57, shown
in dotted lines at Figure 4. The release key 46 or some part of the releasing
mechanism may be provided with an individual returning spring 58.
Referring now to Figures 7, 8, 9 and 10, the modification therein shown con-
cerns particularly the parts carried by the carriage. In these views will be
found actuating devices for the rod 24 of different detail construction; the bar
upon which they are mounted is pivotally connected to the carriage and instead
of providing a releasing mechanism at or in the vicinity of the keyboard as in
Figure 1, the said releasing mechanism will be found connected with the paper
carriage.
The slotted bar 54 is connected to the paper carriage by links or pivoted
arms 59 and 60. The slotted bar 54 carries one adjustable actuating device 61
and one fixed or non-adjustable actuating device 62. These are constructed alike
excepting that the adjustable device has a set screw 63 for clamping it in the
desired position.
These devices are provided each with a beveled inclined or cam face 27 and an
adjacent plane horizontal portion 28" formed on the underside of the rearwardly
projecting device, and which at its inner end is channeled or formed with shoulders
to embrace the sides of the slotted bar 54 as shown more particularly at Figure 9.
The shank of the set screw 63 for the adjustable device, passes through the slot
in the bar 54 and enters a tapped hole in the bottom plate of said device, and
the collar below the head of the screw bears on the top of the slotted bar and
serves to hold the device firmly in its adjusted position, the flanges or shoulders
preventing any side play or swivel action.
As shown at Figure 8, the pivoted cam piece at the upper end of the operating.
rod 24 is replaced by a plane pivoted piece 35" having a rounded corner 64
where it is engaged by the cam face 27" on the slotted bar on the carriage, and
with a plane horizontal top portion 65 for engaging with the plane portion 28"
of the said device. A spiral spring 66 is attached at one end to the link 60
and at its other end to the carriage, and said spring acts to return the slotted bar
towards the left (viewed from the back of the machine) and to hold it there
normally. The link 60 is provided with a projection 67 which engages a pin 68
on the carriage and stops the movement of the slotted bar towards the left under
the influence of said spring. A carriage release key somewhat similar to that
usually provided in the Remington No. 2 machine for raising the feed rack is
also connected to the slotted bar as well as to said feed rack, whereby the escape-
ment mechanism and the type bar intercepting mechanism are both simultan-
eously released. The said release key consists of a rock shaft 69 mounted in
bearings 70 in the carriage frame, a key or hand piece 71, a laterally extending
arm 72 and an upwardly bent arm 73, to which latter is pivoted one end of a
link 74 whose opposite inner end is pivotally connected to the link 60. The
lateral arm 72 overhangs an arm 75 extending forwardly from the rack bar.
By this construction and arrangement when the finger piece 71 is depressed the
shaft 69 is rocked in its bearings, the arms 72 cause the rack bar to swing up-
wardly out of engagement with the dogs, and at the same time the vertical arm 73
of the release key swings outwardly and pulling upon the link 74, causes it to

page_text: pull the link 60 and the slotted bar 54 and the link 59. in the same direction
against the tension of the spring 66. Thus it will be seen that when the cam 27"
has caused the depression of the operating rod 24 and the elevation of the inter-
cepting ring, the type bars may be freed for further action, so as to add: one
ör more letters to the line, by causing the actuator 61 on the carriage to step
over or pass by the said operating rod, by a forward movement of said actuator
instead of by a backward movement of said rod as in the previous views,' and
this forward movement of said actuator it will be seen is effected by a key on
the carriage instead of by a key at the keyboard. On the return movement of
the carriage after such stepping over action, the rear vertical. portion 76 of the
actuator 61 strikes the front vertical portion of the lug 35" and causes this device
to rock on its pivot as before, to enable the said actuator to get back again on
the opposite side of the operating rod, so as to be in a position to" actuate it
again on the next advance of the carriage.
Referring now to Figure 11, the construction there shown is substantially the
same as that shown at Figure 7 with the exception that I have introduced a
release key independently of the rack release key, thus permitting a release of
the type bars without affecting the feed rack. In this construction the release
lever 77 is pivoted at 78 between its ends to the carriage frame and at its rear
end is coupled to the swinging or pivoted actuator carrying frame, composed of
the two links and the supporting bar, by a link or coupler 74 as in Figure 7.
The mode of operation of the devices is the same in this instance as in that
described with reference to Figures 7 to 10 inclusive, excepting that the releasc
key affects only the devices which co-operate with the type bar thwarting
mechanism.
Referring now to Figures 12, 13, 14 and 15, a further modification will be
found there exhibited. The actuating pin 50" is placed on a circularly slotted
disk 79 carried by the carriage feed spring-drum instead of being on the carriage
itself as in Figures 1 to 6. This pin is adjustable in said slotted disk for
acting upon the mechanism at different points in the rotation of the spring
drum and in the course of travel of the carriage, the pin being combined with
a screw and nut as before so as to enable it to be firmly set in the desired posi-
tion. The obstructing ring or device 17 is connected by the stem 18 to the
lever 20, pivoted at 21, and to the shorter arm 47 of said lever is pivotally mounted
the operating rod 24, in this instance made considerably shorter in length and
of plate-like form. It, however, corresponds substantially in construction and
mode of operation with the rod 24 shown in the previous views. The said opera-
ting rod or plate 24 is guided by an arm or bracket 80 at its lower end and is
connected by a spring 36 to the frame-work, which spring operates in substan-
tially the manner herein before set forth. Pivotally mounted at 26 on the device 24
is a cam piece 25 having an inclined portion 27 and a horizontal portion 28 as
before, but otherwise slightly different in construction. In this instance the
cam piece is provided with a projection 81 which normally presses against a
stop pin 82 on the device 24 and limits the pivotal action of the cam piece under
the influence of its individual spring 33, and the said cam piece is also provided
with a downwardly extending arm 83 which is pivotally attached by a screw
to the slotted end of a link 84 which is pivoted at 85 to an upright lever 80
fulcrumed at 87 in a bracket 88 and provided with an individual spring 89.
The upper end of the lever 86 is loosely connected to the rear end of a release
key lever 90, which when its key or finger portion 91 is pressed towards the
frame-work of the machine, operates through the lever 86 to force the link 84
inwardly and by reason of its connection to the crank arm 83 of the cam piece
the latter is tilted or vibrated towards the right (viewed from the back of the
machine) as shown at Figure 15, and is thereby released from the actuating
pin 50, and when so released enables the operating rod or plate. 24 to rise and
cause the intercepting ring 17 to descend out of the path of the type bars.
At Figure 12 the parts are in their normal positions and the pin .50 is approach

page_text: ing the cam piece. At Figure 14 the said pin is shown as having forced down
the cam piece and the rod 24 and lifted the lever 20 so as to move the intercept-
ing ring into the path of the type bars. If now it should be desired to write
beyond this point the release key is operated as before explained and the cam
piece is thrown back to the position shown at Figure 15. On the return move-
ment of the carriage the square face of the pin acting upon the square face of
the cam piece will also tip the cam piece back as shown at Figure 15, so as io
permit said pin to pass by and again get behind the cam piece, in order to operate
the parts anew at the predetermined end of the next line of writing. The
lever 20 may be provided with a projection at 92 adapted to a pin 93 on a
bracket 94, so as to serve as a supporting means for the weight of the lever and
the intercepting ring when in their normal positions, and also as a stop for
these devices and the vertically-arranged rod or plate 24, and whereby the latter
is held always at the proper elevation to enable its cam piece to co-operate with
the pin or device which actuates it. The stem of the ring and hence the ring
itself, may be guided by an eye 95 formed in the upper end of an arm or
bracket 96 attached to the bed plate or frame.
Referring to Figure 16, a still further modification of means for depressing
the operating rod 24 is shown. In this case the cam piece, constructed similarly
to that shown in Figures 12 to 15 and provided with an individual spring, is
pivoted upon a lever 97 fulcrumed at 98 on a stand or bracket 99 on the frame.
An adjustable pin as 50 on the carriage is adapted to co-operate with said cam
piece to depress said lever and the depression thereof in turn effects a depression
of the operating rod 24; connected to the intercepting ring as in the previous
instances. The free end of said lever is provided with an inclined portion, thus
forming a notch or recess 100 at this locality, a horizontal portion 101 and a
hook or projection 102. Normally the horizontal portion 101 rests on top of the
upper end of the rod 24. After the cam piece and lever have been pressed down
by the pin and the rod 24 has been depressed the latter may be released if desired,
so as to release the intercepting ring and enable further printing to be done on
the line, and this release may be effected by a key such as shown in the first
form,. Figures 1 to 4. When the rod 24 is thrown to the left (considered from
the back of the machine) while the lever 97 is held down by the pin, the rod
rises independently into the notch; under the action of its spring 36 and the
intercepting ring is brought down out of the way of the type bar, thus leaving
the latter free to be operated and additional letters to be printed upon the line.
On the return movement of the carriage, the cam piece is adapted to vibrate
independently as before to allow the pin to pass by.
The cam piece is provided with an inclined portion 27 and a horizontal or
flat portion 28; it is also provided with a projection 81 which normally presses
against a stop pin 82 on the lever 97 and limits the pivotal action of the cam
piece under the influence of its individual spring 33, which is attached at one
end to a lug or projection on said cam piece and at its opposite end to a pin on
the lever 97.
Referring now to Figures 17, 18, 19, 20 and 21, the invention is there shown
as applied to that description of writing machines known as the "Caligraph",
and which is one where the type bars carry only one type instead of two as in
the Remington machine.
The construction and mode of operation of the mechanism is substantially
similar to that shown at Figures 1 to 6. In this case, however, the actuating
pin 50 (which like the other actuators travels only when the carriage travels)
is adjustably mounted in a curved or arc-shaped slot 103 formed on or carried
by the carriage driving arm 104 which, by the link 105 is connected to the car-
riage and which arm is attached to a spring actuating driving shaft 106
beneath the key levers as customary in the caligraph machine. The operating
rod 24 has at its upper portion a cam piece as in Figures 1 to 6, and to the upper-
most portion of said rod is connected a spring as 36 which acts in the same manner

page_text: as the previously referred to spring 36. The lower end of the rod 24 is pivotally
connected to the rear shorter arm 20, of the lever 20, which at its forward end
supports the stem 18 of the intercepting ring. When the pin 50 on the arm 104
strikes the inclined face of the cam piece, the rod is forced downwardly and the
ring upwardly into the paths of travel of the type bars, thus preventing them
from moving to the printing point as before. When it may be desired to restore
the intercepting ring to its normal position so as to permit the addition of one
or more letters to the line, a release key mechanism connected to said rod may
be operated to produce this result. The said mechanism in this instance com-
prises a link 107 pivotally connected at its inner end to the rod 24 and pivotally
connected at its outer end to the upright arm 10S of a bell crank lever com-
prising said arm, a long pivot or rock shaft 109 and a laterally extended arm 110,
to which is pivotally attached the lower end of a spring pressed stem 111 having
at its uppermost end a key or button to receive the pressure of the finger. When
this key is depressed the rod 24 is pulled over towards the left (viewed from the
back of the machine) and the cam picce thereon is thereby disengaged from its
actuating pin, whereupon the intercepting ring is restored to its normal position,
while at the same time the cam piece is carried to a non-working position rela-
tively to its actuating pin and the key levers may then be operated to produce
additional printing on the line. On the return movement of the carriage as the
driving arm 104 vibrates in the opposite direction the pin thereon strikes the
cam piece on the side opposite the inclined portion, vibrates it independently
on its pivot and then passes by it as previously explained, after which the said
cam piece is automatically restored to its normal position by means of its indi-
vidual spring. I have shown two actuating pins on the driving arm 104, both
of which are adjustable in the slot thereof so as to cause the obstruction or inter-
ception of the type bars twice if desired during a single vibration of the driving
arm from left to right. (considered from the back of the machine).
In all forms of my invention it will be seen that the device for preventing
the type bars from printing is one which is of such size and shape as to cover,
include or embrace all of the type bars of the machine, and is so situated as that
normally it is out of the paths of travel of all of said type bars, but when actuated
is moved directly into the paths of travel of said type bars, so as to thereby posi-
tively obstruct or intercept them. It will also be seen that in all forms of my
invention, some means are provided for restoring the intercepting device to its
normal non-working position after the type bars have been once obstructed so
as to permit printing of additional characters on the line.
Having now particularly described and ascertained the nature of the said in-
vention 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 a series of type bars, and an
intercepting device normally out of the paths of travel of said type bars but
arranged to be automatically moved directly into the paths of travel of said
tyne bars.
2. In a typewriting machine, the combination of a series of type bars, an
intercepting device normally out of the paths of travel of said type bars, and
means for automatically moving said intercepting device directly into the paths
