Improvements in Printing Telegraphs.
W WILLIAM WALLACE TAYLOR of Mansfield in the County of Bristol and State
of Massachusetts, United States of America, and ELLEN MARIA LEAVENS of
No. 245, Cranston Street, Providence in the County of Providence and State of
Rhode Island United States of America, 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 :-
Our invention relates to improvements in printing telegraphs and the object of the
invention is to provide an apparatus by which typewritten messages may be sent by
telegraph, and recorded at both ends of the line by a person not familiar with telegraphy,
also in providing means for sending printed and dot and dash messages to different
points over different lines at one operation, and also to so construct the apparatus that
a single tap upon a key, as the key of a typewriter, will transmit a whole letter or
character, and record the same at both ends of the line.
A further object is to provide means for making the proper line spaces on the printed
message, and to automatically print and deliver the messages into a public or private
receptacle as desired.
To this end our invention consists in certain features of construction and combina-
tions of parts, which will be hereinafter fully described and specifically pointed out in
the claims.
Reference is to be had to the accompanying drawings, forming a part of this
specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.

We have shown our invention in the accompanying drawings as applied to an
ordinary Number 2, Remington typewriter, but it may be easily applied to any style
of typewriter, the necessary alterations being purely mechanical and not affecting the
principle of the invention.
The frame of the apparatus B, is mounted on the same plane and in line with the
typewriter A, it being immediately behind the typewriter and connected therewith

page_text: in a manner hereinafter described. The arrangement is the same at both ends of the
line, the device acting both as a receiving and transmitting instrument.
In the drawings the printing device is shown in circuit with the line wire 1, so that
a printed message will be sent over it to one point, and the dot and dash device in
circuit with another line wire 2, which for use at a receiving station would be connected
up with an ordinary recording instrument, but which at the transmitting station could
be connected with another line, so that a dot and dash message may be sent over it to
another place at the same time and at one operation.
The printing device and the dot and dash device are connected by wires 1 and 21,
respectively, to main batteries and ground wires in the usual manner to complete the
circuit, each device being connected with a separate battery.
At the top of the device is a circular dial plate C, having the desired letters, figures,
and characters arranged around it, and beneath each character is a system of connection
with the corresponding character of a typewriter and with a key representing the
character in dots and dashes.
The dot and dash device proper consists of the following parts. A standard 3, having
extending arms 4, in which is pivoted a circular disk 5, having a pinion 6, attached
thereto which meshes with the toothed rod 7, that moves vertically at the side of the
disk 5 through bearings in the arms 4 and 8 of the upright 3, the edge of the disk 5
being provided with projections 9, of different lengths which represent the character
to be transmitted; opposite the disk 5 is an upright 10, having an arm 11, with a
projection 12, pivotally attached to the top thereof, said arm having its upper
end provided with a projecting spring 13, which engages the studs 14 and 15, on
the disk 5, and having its lower end bent and supported by a spring 16, attacked to
the upright 10.
The top of the rod 7 is provided with a button 17, and coiled around the upper end
of the rod between the arm 8, of the upright 3, and the buston 17 is a spiral spring 18,
so that when the rod 7 is depressed the spring 18 will raise it again as soon as the
pressure is removed. The disk 5 is connected with the line wire 2 through the
upright 3, and the arm 11 with the battery and ground wire 2¹ through the upright 10.
When the rod 7 is depressed the gear on the rod acting upon the gear 6, turns the
disk 5 and brings the projections 9 of the disk successively in contact with the
projection 12 of the arm 11, thus completing the circuit and sending pulsations over
the wire that will correspond in length with the length of the projections 9 of the
disk 5, as the circuit is only complete when these projections are in contact with the
projection 12 of the arm 11; and as the projections 9 and the spaces between said
projections vary in length to make dots and dashes representing a particular character,
the whole character will thus be transmitted by one tap upon the rod 7 and oscillation
of the disk 5.
When the disk has turned sufficiently for the projections 9 to have passed the
projection 12, the stud 14 upon the side of the disk will strike the spring 13, and tip
back the arm 11 to which it is attached, so that when the disk is turned back by the
action of the spiral spring 18 as described, the projections 9 will not strike the pro-
jection 12, but after the disk turns back till the projections 9 have all passed the
projection 12, the other stud 1 will strike the top of the spring 13, and tip the
arın 11 and projection 12 back into their original position ready for use. The instru-
ment is put in connection with the wire to be used, by means of a switch in the usual
manner.
The rod 7, is connected at the top with the type levers 20, of a typewriter which
connect with type bearing the characters represented by the dots and dashes made by
the projections 9 of the disk 5 as above described, so that when the type ievers 20 are
depressed to record and transmit the message as bereinafter described, they will
depress the rods 7 and also transmit and record the message in dots and dashes.
In the center of the dial plate C is a vertical spindle 21, which stands upon a cross
plate of the frame B and upon which is journaled an ivory sleeve 22, to which are
attached the pointer 23, and contact arm 24, arranged one above the other, and
insulated from each other and from the spindle 21 by the ivory sleeve 22.

page_text: The pointer 23, indicates the letters to be transmitted, and is provided with a
key 25, which is supported by a spring 26, which is attached to the pointer, and is
provided with a depending spindle 27, which projects through the pointer 23 and
passes by the contact arm 24 for contact with the rod 28. The dial plate C is
connected with the ground wire 11 and is provided with projections or contact
pieces 29, arranged nearly opposite each letter of the dial plate, so that when the
pointer 23 is over a certain character, the end of the contact arm 24 will come in
contact with the contact piece 29 opposite the same character and complete the circuit,
the current passing through the contact arm 24, metal plate 30, which encircles the
sleeve 22 and rests lightly against the under side of the contact arm 24, flat spring 31,
magnet 33, which is supported by the arm 32, attached to standard 46, and then over
the line wire 1 to the instrument at the other end of the line.
The current from the line wire 1 is shunted at the point a, a part of the current
going through the magnet 33, spring 31, metal plate 30, contact arm 24, and contact
piece 29, to the dial plate C, and the other part passing through the spindle 21, to the
magnet 34, and pointer 23, to which said magnet is fixed, then through spring 26,
spindle 27, rod 28, type lever 20, to the point 6 in wire 1'.
When the spindle 27, comes in contact with the rod 28, the circuit is complete
throughout the device. We will now suppose the letter T is to be sent as indicated
by the pointer in Figure 1 the key 25, is depressed thus forcing down the rod 28, which
is forked at the end and straddles the type lever 20 of the typewriter, so that this
acting on the type lever 20 will print the letter T, on the transmitting end of the line,
and will also depress the rod 7 of the dot and dash device and send the lotter T in
dots and dashes; the current will enter the instrument at the other or receiving end
of the line over the line wire 1 and will pass up the spindle 21 to the magnet 34,
which being attached to the pointer 23, will be over the T key of a typewriter, as at
this end of the line, as will be explained hereinafter, the current acting through the
magnet 34, will raise the armature 35, which is attached by an arm 36, to the rod 28,
so that when the armature 35 is raised it will raise the rod 28, and loop 37, of
said rod, thus tilting the walking beam 38, which is pivoted to the upright 39, and
one end of which enters the loop 37 forcing down the rod 40, one end of which is
attached to the walking beam 38 and the other to the type lever of a typewriter, and
printing the letter T at that end of the line. The drums of the magnet 34 are made
hollow to allow the armature 35 to project into the same so as to give sufficient
movement to the type levers 20 to effect the printing. This action will also operate
the dot and dash device as heretofore described. Each type lever of the typewriter
is provided with the mechanism just described, which is arranged opposite the
character on the dial plate C, represented by the type lever to which the mechanism is
attached.
The pointer 23 and contact arm 24 are moved around the dial plate C by taking
hold of the key 25 and moving it to the desired letter or character. As the pointer
is moved around, the end of the contact arm 24 will touch the contact pieces 29
arranged around the dial plate opposite each letter or character, and when the pointer 23
touches a contact piece 29, the current will pass through the pointer, through the metal
plate 30, spring 31, and magnet 33; the magnet 33, acting on the armature 41, which
is attached to the spring 42, will draw said spring away from the ratchet wheel 44,
with which it engages by a pawl 43, attached to the one end of the spring.
The armature 41 is just far enough from the magnet 33 so that when the armature
is drawn against the magnet it will pull the pawl 43, back one tooth on the ratchet
wheel 44. A dog 45, attached to the standard 46 engages the teeth of the ratchet
wheel 44, and prevents the same from turning back. The spring 42 is also attached
to the standard 46. The ratchet wheel 44 is fast to the spinale 21, so that when the
ratchet wheel is turned the spindle will turn also, and as the notches or teeth on the
ratchet wheel represent the same arc of a circle as the space between the contact
points 29, when the ratchet wheel is turned the distance of one tooth, the pointer being
attached to the spindle 21, will move one space on the dial plate.
When the pointer 23, and contact arm 24 are moved a little further around the dial

page_text: plate C, the contact arm 24 will be removed from contact with the contact piece 29, and
the current will be broken, consequently the magnet 33 will release the armature 41,
and the action of the spring 42 and pawl 43, will push the ratchet wheel 44 around
one notch or the width of a tooth, and this action will be transmitted and duplicated at
the other end of the line by the current acting on the parts described; every time a
character and contact piece 29, is passed this action will be repeated so that the
pointer 23 and contact arm 24, on the other or receiving end of the Ine will indicate
the same characters that they do at the transmitting end of the line, and the magnet 34
will always be above the proper armature 5 which actuates the type lover of a type-
writer by means of the connecting parts already described. The dial plate C is
provided with a space 93, in which there is no character represented, but a contact
piece 29, is placed opposite the space; when connection is made and the key 25
depressed, the same action will take place on the spacer levers of the typewriters at
both ends of the lines, as upon the type levers just described, and the required
space made between the words. If necessary or desirable, additional spaces may
be arranged upon the dial plate, and suitable connections made with the additional
spaces and the spacer levers of the typewriters. When the pointer 23, and contact
arm 24, are moved around the dial plate C, if the spindle 27, was allowed to
come in contact with the rod 28, the circuit would be completed and a character
transmitted every time such contact was made, and as the contact would be made
every time the pointer and contact arm passed a character of the dial plate and
the spindle came above one of the rods 28, the result would be very confusing. To
prevent this, an ivory insulating plate 47, is pivotally attached to the under side
of the pointer 23, so that it may be swung under the spindle 27, and prevent it
from coming in contact with the rod 28.
The plate 47 is actuated by a spring 48, attached to the pointer 23, near the
plate 47, which has a tendency to throw the plate from under the spindle 27 and
allow the spindle to be pressed upon the rod 28, but the spindle 27 is provided
with a lever 49, which strikes a stud 50, on the plate 47, so that when the spindle
is turned to the left by means of the key 25, the lever 49 acting on the stud 50
will hold the plate 47 beneath the spindle 27 and so keep the spindle insulated from
the rod 28.
In turning the spindle 27 to the left the lever 49 enters an inclined slot 51, in the
sleeve 52, of the spindle so that the spindle is raised and insulated from the rod 28 at
the same time.
In moving the pointer 23 and contact arm 24, the key should be turned to the left
and held in that position until a character is reached that is to be transmitted, when
the fingers are released from the key 25, and the spring 48 will throw the plate 47
from under the spindle 27, and allow the same to drop into contact with the rod 28.
The stud 50 that is attached to the plate 47 is made U-shaped as shown in Figure 9,
so as to admit of the spindle 27 being depressed, the lever 49 attached to said spindle
moving freely between the sides of the stud when said spindle is depressed.
If the message sent is to be recorded at both ends of the line, it will be
necessary to depress the key 25 sufficiently to operate rod 28 and the type
levers 20 of the typewriter at the transmitting end of the line every time a
character is transmitted, but if the message is only to be recorded at the receiving
end of the line, it will only be necessary to bring the spindle 27 in contact with
the rod 28, thus completing the circuit and causing the magnet 34, armature 35,
arm 36, loop 37, walking beam 38, and rod 40, to actuate the type lever 20, of
the typewriter at the receiving end, as already described..
We have described the mechanism for operating the type levers of the type-
writers and for transmitting dot and dash messages, and will now describe the
mechanism for operating the typewriter carriages and for regulating the delivery
of the printed messages into a public or private receptacle. The carriage 54, is
of the usual construction and is adapted to slide across the frame as in ordinary
typewriters, being mounted on a suitable rod on the frame A, and on suitable trucks
in the rear, and being pivoted so that it may swing upwardly in the usual manner.

page_text: The carriage has the usual printing cylinder 55, the feed roll 56, adjacent
thereto to regulate the passage of paper over the cylinder, the usual frictional
means of operating the feed roll, the rack 57, connected with the carriage and
adapted to slide on the rod 58, of the frame A, the usual means of tilting the
rack so as to permit the free movement of the carriage, the spring-actuated
pawl 9, to engage the under teeth of the rack and limit the movement of the
carriage to one letter space at a time, the spring barrel 60, indicated by dotted
lines in Figure 7, to move the carriage, the bell or gong 61, which is sounded
at the end of a line, and the lever 62, for raising the carriage and tilting the
rack, said lever being connected by the part 62, which extends above the cylinder,
with the arm 57, which is pivoted on the rod 58, and connected with the rack 37,
so that when the lever is raised the arm will be tilted and the rack raised from
engagement with the pawl 59. The part 62" is also provided with an arm 62, in
which is pivoted the pawl 62, which engages the ratchet wheel 5*, of the cylinder,
so that when the lever 62 is raised the cylinder and feed roll will be turned.
The above construction is similar to the ordinary typewriter of the type named,
with the exception of the rack 57, and needs no detailed description. The rack 57,
instead of being notched on the lower edge only as in ordinary typewriters, has
similar notches upon its upper edge.
Mounted on each end of the carriage 54, is an upwardly-extending curved support 63,
and fixed between said supports so as to extend longitudinally above the carriage, is
a hollow cylindrical box 64, composed of two semi-cylindrical parts, hinged together
at the rear as shown, and having a suitable lock 65, in front. The box 64 is to contain
private messages and has an opening 64, in the bottom, and a guide 64b, extending
outwardly from the lower side of the opening to direct the messages into the box.
The supports 63 are provided with hangers 63, in which a paper supply roll 65° is
hung, and extending forwardly from between the supports are the guides 66 and 67,
the lower guide 66 being adapted to direct the paper from the roll 65 between the
feed roll 56 and printing cylinder 55, and the upper guide 67 being adapted to direct
a public message from the cylinder 55, above the roll 65 to the rear of the machine.
The length of these guides should correspond to the length of the cylinder and feed
roll, and the width should be such as to adapt them to the purpose intended.
Fixed to each end of the frame A, is a vertical arm 68, which extends above the
printing cylinder and feed roll, the upper ends of said arms being connected by
the parallel bars 69, which are a short distance apart, and in vertical alignment,
and which are directly above the central point between the cylinder 55 and
the feed roll 56. The height of the bars 69 above the cylinder is such that
the paper that passes over the cylinder will easily pass between said bars to th
rear of the machine. A knife 70, is vertically movable against one side of the bars 69,
said knife corresponding in length to the length of the bars, and being held against
the same by the springs 72, which are attached to the arms 68 on each end of the
The knife is
machine, and which press against the back side of the knife frame.
sharpened upon its upper and lower edges, so that when moved past the opening
between the bars 69 in either direction, it severs the paper upon which the messages
are written. Extending rearwardly and upwardly from the upper portion of the knife
is a guide 71, which when the knife is below the opening between the bars 69, directs
the message upon the guide 64° and into the private box 64. When the knife is above
the opening between the bars the message will pass below the knife and over the
guide 67 to the rear of the machine, said message being a public one.
A frame 73, is attached to each end of the knife 70, said frame extending beneath
the machine and below the type levers 20, said frame being provided with a pair of
upwardly extending ears 75, by which it is pivoted to a lever 20°, as indicated by
dotted lines in Figure 3, which lever is pivoted with the type levers on a rod 74, and
which is connected by a rod 28 with the dial C, and is operated like the other levers.
In the upwardly extending ears 75 of frame 73 is also pivoted the end of a short
lever 20b, as shown by dotted lines in Figure 3, which lever is pivoted in the support 76,
and extends beneath the dial C, with which it is connected by the same mechanism as

page_text: the type levers. The dial is provided with characters 77 and 78, opposite the connections
of the levers 20 and 20%, said characters being marked "private message
" and
"
public message" respectively, so that when the pointer 23 is brought opposite the
character 77, the lever 20 will depress the frame 73 and knife 70, and the message be
delivered into the box 64, and when the pointer 23 is brought opposite the character 78,
the lever 20 will raise the frame and knife, thus shutting off the box and delivering
the message over the guide 67 to the rear of the machine.
A curved shield 79, is fixed to a shaft 80, which is pivoted to the arms 68 opposite
the upper bar 69, said shaft being provided at its ends with cranks 81, which are
fixed thereto, and which are pivoted at the ends to the rods 82, which extend
downwardly and are pivoted to the knife frame 73 at each end of the machine,
so that when the knife frame is depressed that a private message may be delivered,
the rod 82 will actuate the crank 81 and shaft 80, and cause the shield to be
moved downwardly over the cylinder 5, as indicated by dotted lines in Figure 3, thus
screening the cylinder from view, and preventing the message which is being written
from being read as it passes over the cylinder. The dial has the usual characters
indicating upper case and lower case type, and opposite these characters is the same
mechanism that operates the type levers 20, but the levers connected with said
mechanism shift the cylinder 55 in the usual manner to adapt it to receive the
upper or lower case type. A sleeve 83, is mounted upon a suitable pivot rod 83ª,
said sleeve having the two opposite and laterally-extending arms 83 and 83b, and
the upwardly extending arm 83, the upper end of which enclosed by the ears 84,
on the carriage 54, so that when the arm is moved the carriage will be moved to
bring the cylinder 55 into alignment with the desired form of type. The arm 83*
is connected with one of the levers 20°, by a rod 85, and the arm 83b is connected
with another of said levers 20', by the rod 86, which has a loop 86, in the end
that engages said arm and so permits a limited movement of the rod before the
arm is actuated. The arm 83 is also provided with a spring 87, which is connected
by a rod 87, to the lower side of the arm, and to a standard of the frame A, and
the tendency of the spring is to hold the carriage and cylinder in position for
dower case type. The levers with which the rods 85 and 86 are attached, are
connected with the transmitting mechanism opposite the upper and lower case
characters on the dial C. so that when the pointer 23 is opposite the upper case
character on the dial, and the key 25 depressed, the lever connecting with the
sending mechanism opposite said character will be depressed, thus depressing the
rod 85, tilting the sleeve 83, and actuating the arm 83, thereby moving the carriage
backwardly and bringing the cylinder 55 into position to receive upper case type.
When the pointer 23 is opposite the lower case character of the dial, and the key 25
is depressed, this action will be reversed, the rod 86 will be depressed, the sleeve 83
turned on its pivot, and the arm 83° and carriage 54 brought forward, bringing
the cylinder into position to print lower case type. A dog 88, is centrally
pivoted to a depending lug 89, of the frame A above the arm 83b, said dog having
at one end a hook 88, to engage the end of the arm 83 and having the other
end provided with a spring connecting above with the frame and which serves to
hold the dog hook in engagement with the arm 83b. A rod 90, is pivoted to the
inner end of the dog 8s and extends downwardly therefrom and is pivoted at its
lower end to the rod 86. It will thus be seen that when the rod 85 is depressed
to throw the carriage into position for upper case printing, the hook 88* of the
dog 88, will engage the arın 83, and hold the parts in this position till the rod 86
is depressed to put the machine in position for lower case printing, when the
rod 90 will thus be actuated and will depress the inner end of the dog 88 and release the
hook 88" from the arm 83b, thus permitting the necessary movement of the carriage.
A vertical frame 91, is pivoted in suitable supports 92 of the frame A, said frame
baving a top piece or rod 91", which bears against the cylinder lever 62, the frame
being long enough for the lever to bear against the rod throughout the movement of
..the carriage 54. The lower portion of the frame is fixed to a short lever 20%, which
..extends beneath the dial C, parallel with the levers 20, said lever being connected

page_text: وو
with the same mechanism as the levers 20, the mechanism being arranged opposite a
character 93, on the dial, marked
" space, so that when the pointer 23 is
brought opposite said character, and the key 25 depressed, the lever connected with
the frame 91 will be depressed, and the frame thrown against the lever 62, thus
actuating the lever and cylinder 55 connected therewith, and turning up the paper 6 *
upon which the messages are printed, the distance of one line, in the usual manner.
A lever 20, extends parallel with the levers 20, is pivoted at the point 76 instead of
at 74, and is provided at the rear end with a vertical arm 94, having a hammer 95, at:
the end thereof, said hammer being arranged beneath the gong 61, which is the
ordinar typewriter gong, but a heavier one may be substituted if desired. The
lever 20 is connected with the same mechanism as the levers 20, so that to sound
the gong it is only necessary to turn the pointer opposite the space marked "bell" on
the dial and depress the key 25, when the lever 20 will be tilted and the hammer 95
forced against the gong. The object of the bell mechanism is to give notice that a
message is about to be, or has been, transmitted. The machine is provided with the
usual cross bar 96, extending beneath the levers 20, and the rods 97, levers 98, and.
connecting rod 99, connecting with the pawl 59, so that every time one of the levers.
is operated the carriage moves one letter space.
The dial space C has a character 77, thereon which is marked with letters to.
indicate that it represents a space key, and opposite this character is the same
operating mechanism that is arranged opposite the other characters of the dial, said
mechanism connecting with the space lever 20¹, of the typewriter which is arranged
in the usual manner, so that by bringing the pointer 23 opposite the character 77º,.
and depressing the key 25, the space lever of the typewriter will be operated.
The following mechanism is employed to return the carriage and cylinder to the
left of the machine after a line has been printed, and the paper turned up a line space..
A lever 20, is arranged parallel with the levers 20 so as to extend beneath the dial C.
and the end of the lever beneath the dial is provided with the same mechanism as the
other levers, said mechanism being arranged opposite a character 100 on the dial
which is marked
"carriage" or with words or letters of similar import. The
lever 20 is pivoted at the point 76 instead of at 74, and is pivoted at its rear end to a
vertical rod 101, which extends up the back side of the machine and has a pawl 102,.
pivoted to its upper end, adapted to engage the notches on the upper edge of the
rack 57. The rol 101 is provided near its lower end with a boss 103, which is
insulated from the rod and is connected with one of the wires 104, of an ordinary
electric battery 105. A spring 106, is insulated on the frame A so as to extend above
the boss 103, said spring having a contact piece 107, attached at its free end, which
aligns vertically with the boss 103, and having at its fixed end a block 108, which is
connected by a wire 109, with the magnet 110, which is mounted on a suitable.
support 111, and the wire 109 after being wound upon the magnet connects with the
block 112, of the spring 113. The spring 113 is formed at its upper end into.
a book 113, one side of which presses against the rod 114, and the other against the
screw terminal 116. The rod 114 is pivoted to the pawl 102 and extends down-
wardly therefrom between the spring 113 to which it is fixed, and magnet 110, the
rod being provided on the side next the magnet with a suitable armature plate 115,
which is properly insulated thereon. The screw terminal 116 is mounted in a
suitably insulated support 117, which is connected with one of the battery wires 104*.
The above mechanism works very similarly to the ordinary electrical push button for
ring bells, the spring 113 serving to make and break the circuit. When the rod 101
is raised, the pawl 102 engages the rack 57 and the boss 103 is brought in contact
with the contact piece 107, thus completing the circuit, the current passing through
the boss 103, spring 106, wire 109, magnet 110, spring 113, terminal 116,
support 117 and wire 104 back to the battery; the magnet 110 then pulls
forward the armature 115, which actuates the rod 114 and pawl 102, and pushes the
carriage one notch or more. When the armature and rod are pulled forward, the
spring hook 113 leaves the terminal 116, thus breaking the circuit, and the armature
and rod fall back into their original position, carrying back also the pawl 102 and

page_text: rol 101; the circuit is again completed and the action repeated, and it will continue
to be repeated while the rod 101 is held in an elevated position, and until the
carriage 54 is returned to the left of the machine.
As described above, when the pointer 23 is brought opposite a certain character on
the dial, the pointer on the dial at the receiving end of the line is likewise moved, the
operation being transmitted by the wire 1; if, however, characters are to be printed
and the operation is to be duplicated and recorded at the transmitting end of the line,
the key 25 must be depressed every time the pointer is moved, in order that the
appropriate levers and their connected parts may be actuated. the action being
imparted to the type levers and carriage and bell levers by the rods 28 connecting
said levers with the key 25.
A paper supply roll 65 is hung in the machine as described, and the paper
entered between the feed roll and printing cylinder, and as the machine is operated
the paper is fed between said parts in the usual manner. If a private message is to be
sent, the pointer 23 is brought opposite the character 77 on the dial, the key 25
depressed and the knife and shield will be lowered as described and the message
delivered into the box 64. If a public message is to be sent, the pointer is brought
opposite the character 78 and the message will be delivered to the rear of the
machine, the parts operating as described, and to operate any part of the machine it is
only necessary to bring the pointer opposite the character representing said part on
the dial and depress the key 25, the desired movement will be accomplished by the
type levers 20 and the corresponding levers extending beneath the dial and connected
with the operative parts of the machine in the manner described, the movement being
transmitted to the receiving end of the line as heretofore described.
The printing and the dot and dash apparatus may be used together or separately,
and the dot and dash messages may be recorded on a tape in the usual well known
manner, but it will be necessary to speed the tape higher than in the ordinary
machine as the messages will be transmitted much faster.
The dial may be provided with short words of one syllable, and the typewriters
with corresponding type, the parts being connected as described, thereby increasing
the speed of the machine. Messages may also be sent in stenographic signs or in
cipher, by making the necessary changes in the dial and in the type of the typewriter.
