Improvements in Telegraphic Transmitters.
We, SAMUEL PRICE, Watchmaker, of No. 29 Armory Place, Paterson, New
Jersey, WALTER POLK PHILLIPS, Journalist, of No. 253 Broadway, New York
City, New York, and RODERICK HENRY WEINY, Electrician, of No. 253 Broadway,
New York City, New York, all in the 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:.
This invention is directed particularly to a novel form of key-board transmitter
adapted to transmit Morse or analogous telegraphic codes, and its objects are:-
First, to so devise a transmitter of the type indicated that an operator may
manipulate the keys thereof at will without in any manner effecting the regular
and even automatic sending of the prepared message; second, to devise a key-
board transmitter which will enable an operator to store up or accumulate a pre-
pared message at any desired speed in advance of its automatic transmission;
third. to devise a key-board transmitter in which all of the impulses transmitted,
whether dots or dashes are made up by utilizing mechanism which under normal
conditions is adapted to transmit dots, and under variable changes to transmit
dots or dashes, or both, combined with the usual spaces which separate such
eler ents in the well known Morse characters; fourth, to devise a key-board trans-
mitter in which the keys are caused to actuate through the agency of combination
controlling mechanism the desired effect upon transmitting mechanism in such
manner that a Morse message is set up or arranged at such speed as suits the will
of the operator, and the same is automatically transmitted at a comparatively
constant speed dependent upon the speed at which he operates; fifth, to devise a
key-board transmitter in which the transmitting part of the apparatus is driven
by a continuously driven source of power automatically controlled in its operation
by the keys as they are actuated, the arrangement being such that the actual speed
of transmission is comparatively constant, while the speed of the transmitting
medium during the formation of the characters to be transmitted is intermittent
and may be varied to suit the will of the operator; sixth, to so simplify the
operative parts of a key-board transmitter that a minimum number of controlling
levers and parts is utilized in the operation of the apparatus; seventh, to provide
a telegraphic transmitter in the nature of an endless chain or flexible transmitting
device, the movable parts of which are adapted to be used over and over again
in the formation and transmission of electrical impulses, such as are usually
utilized in connection with the transmission of Morse and analogous codes.
:
These several objects are accomplished by this invention for a full, clear, and
exact understanding of which, such as will enable other skilled in the art to which
it appertains to construct and use the same, reference is had to the accompanying
drawings, in which,
Figure 1 is a plan view of the improved key-board transmitter; and
Figure 2 a side elevational view thereof;
Figure 3 being an end elevational view as seen looking at Figures 1 and 2

page_text: Figure 4 is a horizontal sectional view taken through the body of the apparatus,
parts thereof being shown in plan view.
Figure 5 is an enlarged sectional view taken on the line y-y, Figure 4, the end-
less transmitting chain, its supporting sprocket wheels and the adjacent operative
parts which control and effect the movement and resultant operation of the same
being shown in elevation.
Figure 6 is a detail perspective view of a detached section of the endless trans-
mitting chain with sliding pins and their lateral circuit controlling extensions.
Figure 7 is a side elevational view of the guiding sprocket wheel which directs
or guides the movement of the push rods or plungers as they act upon the sliding
pins of the endless chain; and
Figure 8 is a plan thereof illustrating also one of the push rods or plungers and
its relation to one of said sliding transmitting pins.
The transmission of electrical impulses of variable length which produce the dots
and dashes and their separating spaces in the Morse code is effected with this
invention by a flexible transmitting medium or an endless chain supported by
two sets of sprocket wheels and provided with sliding pins having secured thereto
circuit controlling devices in the nature of lateral extensions which are normally
located in alignment with each other and at equal distances apart, so that were
this transmitting chain allowed to move continuously while the aforesaid pins are
in their normal positions these lateral extensions would operate upon a two-part
circuit closing lever in such manner as to transmit continuously over the line a
succession of dots separated from each other by equal spaces.
The push rods or plungers above referred to are so arranged relatively to each
other and the endless transmitting chain that they will cause the movable pins to
assume variable positions with relation to each other such that the lateral exten-
sions upon said pins will, when they come into mechanical contact with the two-
part circuit closing lever, according to their location, effect the transmission of a
dot, a dash; or a dot, a space, and one or more succeeding dots or dashes; or, in.
fact any arrangement of dots, dashes and spaces found in any of the characters of
the existing Morse code. The apparatus is so arranged also that one of said push
rods always gives to one of the pins a movement to its extreme limit for the pur
pose of checking the movement of the endless chain as each character is formed,
said endless chain being intermittently driven by a constantly-driven source of
power, the intermittent action of which results from the operation of the keys
upon the chain itself. The transmission of the electrical impulses in turn is
effected by a constantly impelled source of power which is replenished by the
constant source of power in accordance with the action of the operator upon the
key-levers; locking and unlocking mechanism being operatively connected with
all of said key-levers and with a spacing lever in such manner that each letter or
character, set up or formed by the operation of any key-lever or combination of
key-levers upon the movable pins of the endless chain, is released at the same time
that a succeeding letter or character is formed or set up in said chain.
Referring now to the drawings in detail in all of which like letters and numerals
of reference represent like parts wherever used.
A represents the base of the machine, and B. B, B₁ B¹ B² B² upright standards
or posts secured thereto, to which in turn are secured side supports CC, CC¹, C² C²
and end and central supports D D¹ D¹ and C3, all being so connected to the afore-
said standards as to constitute the framework for the entire machine.
K¹ E¹, K² E², K³ E³ and K' E' represent banks of keys such for instance as are
found in the well known "Remington Typewriter," and S K a spacing key, said
spacing key and banks of keys being connected respectively to key-levers L1, L³, L10
and so on, to L43 pivoted and properly spaced from each other upon a rod i beneath
the end support C³, all of said key-levers being normally held in their upper
positions by retractile springs el es el to e¹³ inclusive secured at their upper ends to
a cross-bar. G supported by side standards F F and all provided with spacing

page_text: guides supported by a cross-rod so as to permit of their free and independent
movement in the usual manner.
M is a rocking bar extending transversely across the machine beneath all of the
key-levers and the two levers L₁ L43 which support the spacing key S K and
pivotally secured by adjustable trunnions M M₁ in the side supports B¹ B¹, Q³
being a lever rigidly secured thereto near its center and connected by a link L
with one arm of a three-armed lever pivotally sustained in turn upon a trunnion N
supported by a standard Q Q in the rear of a ratchet wheel O, the second arm ¹ of
said lever being provided with a spring-pressed pawl p adapted to take in the teeth
of said ratchet wheel, see Figure 5, and the third arm 12 thereof being connected
by a rectractile springs to a standard P, s being a spring-actuated check pawl
for regulating the movements of the ratchet wheel.
R¹ R3 R³ to R inclusive, see Figure 2, are rocking bars extending entirely
across the machine beneath all of the aforesaid key-levers and pivotally sustained
by adjustable trunnions M2 M2 to M10 M10 inclusive in the side supports C³ C².
K¹, K2 to K inclusive are levers secured at one end to the rocking bars R¹ to R⁹
and at the other to push rods or plungers P¹ to P⁹ inclusive.
1, 2, 3, see Figures 1 and 2, represent a series of angular lugs secured in a pre-
arranged order to the sides of the key-levers in such manner that when any key-
lever is depressed, said lugs will actuate certain of the rocking bars and give to
them variable thrusts, the lugs 1 having the greatest angle, the lugs 2 a medium
angle and the lugs 3 a minimum angle and the lugs 3 a minimum angle. These
combined parts, to wit;-the rocking levers R1 R2 R³, to R³ inclusive with the
groups of inclined lugs 1, 2 and 3 constitute combination controlling mechanism
adapted to select a definite number of the push rods or plungers P1 P2 P³ to P⁹
inclusive in any desired order, said push rods or plungers having a sliding move-
ment through openings in a circular support secured to one of two cross-bars D2 D²,
which in turn are supported by rods D5 D5 and spaced from each other by
washers D D D14, see Figure 4, said cross bars D2 D2 acting also as a supporting
means for additional parts of the apparatus.
1112 to 19 inclusive represent spiral springs, the function of which is to restore the
push rods or plungers P1 P2 P3 to P° inclusive as the keys are released.
St W SW SW SW2 represent pairs of sprocket wheels supported by
shafts ss journalled respectively in the cross-bars D2 D2 and the end bar D, the
function of said sprocket wheels being to support a flexible transmitting medium,
here shown and described as an endless chain C H, see Figures 3, 5
and 6, said endless chain being of any preferred length and adapted
to run over the two sets of sprocket wheels as they are impelled, the one
set intermittently and the other set with a relatively constant speed dependent
upon the action of the operator, as will be described more particularly in con-
nection with the description of the mode of operation. a a¹ are curvilinear arms,
see Figure 5, extending upward to points near the teeth of the sprocket
wheels SW and S2 W2, their function being to prevent the chain C H from
sticking to the sprocket wheels beyond certain points; and X, see Figures 2 and
4, is a curvilinear restoring device adapted to restore the pins to their normal
condition as the chain leaves the sprocket wheel S2 W2. This flexible or trans-
mitting medium or chain C H is illustrated in detail in Figure 6 and is composed
of a series of oblong links y having a width substantially equal to the width
between the supporting sprocket wheels, the ends of the links being bent upward
at right angles, again outward at an angle of about 30°, then downward and back-
ward, as clearly disclosed in Figure 6, after which they are united together by a
series of sliding yielding pins Pia p¹³ constructed each with a loop at one end and
resembling in all respects a hair-pin, the arrangement being such that when they
are slid into position their outward yielding action will cause them to exert
sufficient friction upon the links of the chain to rest at any point to which they
may be moved, the extreme limits of movement being clearly shown in Figure 6,

page_text: said limits being effected in opposite directions by a series of lateral extensions co
secured to one leg of each pin at a point substantially near the middle thereof.
These extensions, it will be noted, are provided with hooked ends and are so
arranged that when the pins are in their normal positions they are all located in
alignment with each other, as clearly shown in Figures 2 and 4.
gª g², _g² _g², q² ² are guide rolls secured upon shafts carried by the side
supports D2 D2 adapted to guide the flexible transmitting chain in its movement
over the sprocket wheels ST W1 SW1, S2 W2 S2 W2, see Figures 4 and 5. As
this transmitting chain CH hangs in the position shown in Figures 3 and 5,
the looped ends of the pins P12 12 rest in funnel-shaped sprocket teeth g g of a
guiding sprocket wheel U, see Figures 2, 4, 7 and 8, so that they are in direct
alignment with the ends of the nine push rods or plungers P1, P2, P3, P4, &c., to P
inclusive, said funnel-shaped sprocket teeth being adapted to guide the rods or
plungers always into contact with the looped ends of the pins.
W is a gear wheel carried by the shaft S3, and W3 a similar gear wheel running
loosely upon the shaft S4, said gear wheels meshing on opposite sides with a
driving pinion w journalled in the side support 12 and the end support D. The
shaft which supports this driving pinion carries also a star wheel S W, the
three (3) arms of which are adapted to come into mechanical contact with a stop a¹
carried at the free end of a lever 16 supported by a rock-shaft R, see Figures 3, 5
and 7. FW is a friction disc supported by a shaft which in turn supports a
pulley W continuously driven by an independent source of power, as an electric
motor, SW being a friction spring rigidly attached to the shaft which supports
the driving pinion between the gear wheels W and W the friction between said
disc and spring being sufficient to drive the gear wheels W₁ and W and their
attached parts when released but adapted to allow the pulley to run at all times.
Upon the shaft S in alignment with the shaft which supports the gear wheel W²
is a second gear wheel W³ meshing with a pinion w² and adapted to drive through
a series of gear wheels and pinions w², w4, to w &c., a regulating fan R F.
S P is a spiral driving spring which operatively connects the loose running
gear wheel W with the shaft S and train of gearing w W &c., the arrangement
being such that as the gear wheel W2 is driven by the driving pinion it in turn
winds the spring S P and thereby imparts motion to the gear wheel W3, shaft S*
and transmitting sprocket wheels S2 W2, thus giving to said sprocket wheels a
comparatively constant rate of speed dependent upon the tension put upon the
driving spring S P.
+
Referring now to Figure 5 for a detailed description of the locking and control-
ling mechanism which regulates the intermittent action of the sprocket
wheels SW, S₁ W, and the relatively constant action of the sprocket
wheel S² W², S2 W2 and the supported transmitting chain C H. R is a rocking lever
journalled at one end in the standard Q sustained by a vertical standard V, see
Figure 3, and 76 a locking lever provided with a stop pin a¹ for checking and
releasing the arms of the star wheel S W, being an operating lever secured near
the other end of said rocking lever and carrying at its free end a stop pin e adapted
to assume either of two positions in notches kk at the free end of a pivoted locking
lever pivotally secured by a trunnion N¹ upon a lateral extension Q of the
standard Q;s being a spring, one end of which is attached to the locking lever 13
and the other to standard P. a is a triangular shaped lug upon the rear face of
the operating lever adapted to be brought into and out of contact with the teeth
of the ratchet wheel (). 15 is a second operating lever secured to the rocking
lever R at substantially right angles to the operating lever 14 with its free or
curved end located at such a point in front of the transmitting chain C H that
when the movable lateral extensions c c are moved to their extreme positions they
will actuate said second operating lever, as will be more particularly described
later on.
R10 is an additional rock-shaft journalled at its opposite ends in the side sup-
ports D² 12 and carrying at one end a short arm 10 provided with an electrical

page_text: contact adapted to make contact with a second yielding contact 7", said movable
contact and yielding contact being in turn connected respectively to binding
posts BP and B1 P₁ adapted to be connected in circuit with an ordinary telegraph
line. Near the middle of the rock-shaft R2 is secured a two-part yielding circuit
closing lever 17, one of the parts 18 of which is in the nature of a straight arm with
its free end adapted, to make mechanical contact with the lateral extensions c c c of
the sprocket chain CH under normal conditions, while the second arm 19 is curved,
as shown, in Figure 5, so that when said lateral extensions are moved forward a
definite distance from under the straight arm 18 they will make a corresponding
mechanical contact with it, the arrangement being such that one of said lateral
extensions may act upon the arm 18 and the next succeeding lateral extension when
properly placed will act upon the arm and prolong the closure of the circuit
between the contacts carried by the arm 10 and yielding arm 11, as will be more
particularly described in connection with the description of the mode of operation,
which will now be made.
At the outset it is to be understood that one of the most essential features of
novelty of this invention lies in the fact that the lateral extensions ce upon the
sliding pins P1, P12 of the endless transmitting chain CH are utilized to transmit
electrical impulses of such a nature as to effect a Morse message of the well known
character by causing said lateral extensions to assume variable positions with
relation to the two-part circuit closing arm 18, 19, and this is effected thorugh the
agency of the selecting and combination mechanism carried by the key-
levers K¹ E' &c., acting upon the rocking bars R¹ to R9 and push rods or plungers P¹
to P inclusive, there being four possible positions for the aforesaid lateral exten-
sions, as follows:-
First, the normal position where they are all in alignment and will
if
pass,
continuously released, successively under the straight arm 18 of the yielding spring-
pressed transmitting arm and thereby impart to the rocking lever R¹º and hence
to the movable contact arm 710 successive movements of equal duration so as to
effect dot impulses over the line;
Second, the secondary position where one of the lateral extensions c is caused to
assume the second position under the curved arm so that the united effect of two
of such lateral extensions c upon the levers 18 19 is to produce a dash impulse;
Third, the still further advancement of any one lateral extension to a point just
beyond the path of the lever 19 so that no current impulse is transmitted, thereby
effecting the necessary space between the elements of a Morse character; and
Fourth, the still further movement of the necessary lateral extension to its
extreme limit shown in Figures 5 and 6, so that it will pass under the curved end
of the locking lever 15 and rotate the rock-shaft R with its first operating lever 14
and stop e into their upper positions so that the stop e will rest in the upper notch k,
such rotation effecting also a corresponding rotary movement to the arm so that
the stop a near its free end will fall in the path of one of the arms of the star
wheel SW and check the movement of the gear wheel W¹ and hence of the sprocket
wheels S¹ W. These several movements are automatically effected by the operation
of the key-levers, as will now be described it being remembered that the faces of
the lugs 1; 2, 3, having each a different angle or inclination.
An examination of Figures 1 and 2 of the drawings will disclose the fact that
these angular lugs 1, 2 and 3 are differently located or grouped relatively to the
rocking bars R₁ to R inclusive. In other words, it will be seen that each key-
lever is provided with one or more of the inclined lugs and that said lugs are so
arranged as to effect certain of the rocking bars only, it being apparent that by such
an arrangement a combination of results is attained whereby a minimum number of
push rods or plungers P¹ to 19 is utilized.
To illustrate the operation of the apparatus, suppose it is desired to transmit the
word "Telegram."
If the motor which continuously drives the pulley W be set in position so as to
rotate the same in the direction of the arrow, Figure 3, it in turn will impart move-

page_text: ment through the friction disc F W and spring SP to the pinion W which drives
the gear wheels W and W2, thereby imparting continuous motion for the time
being to the sprocket wheels S¹ W₁SW. The chain is continuously driven, there-
fore, over the sprocket wheels until it is stopped, and this is effected by the depression
of any one of the key-levers. Suppose, therefore, that the spacing key SK be
depressed to its full limit, in which event the inclined lug 7 on the side of lever 43
will impart to the rocking lever E and hence to the lever, K¹ and push rod or
plunger P1, a stroke of sufficient length to force that one of the sliding pins Pi
which rests opposite its end in the guiding sprocket wheel U to its extreme limit,
see Figures 6 and 8. This action, therefore, places the lateral extensions cin
alignment with the curved end of the second operating lever so that when the
sprocket wheels are moved forward to stich a point that said lateral extension will
pass under this curved end it will impart, through the operating lever and rock-
shaft R, a sufficient movement to place the locking stop al at the free end of the
lever 6 directly in the path of one of the arms of the star wheel SW, thereby
checking the star wheel and hence the movement of the sprocket wheels S¹ W¹.
At the same time that the spacing key was depressed the rocking bar, M was moved,
causing the lever Q to lift the link L and hence to move the three-armed lever 11112
to such an extent against the action of the spiral spring s as to place the pawl p
in the next succeeding tooth of the ratchet wheel O so that when the spacing key
is released, the springs acting upon the arm will impart to the ratchet wheel
one step, causing that one of its teeth which lies above the lug a upon the lever
to restore the operating lever 14 to its lower or normal position, so that the stop e
is again placed in the lower notch of the spring-actuated lever 3. This action,
therefore, again restores the second operating lever to its normal position ready
to be actuated by the next succeeding lateral extension which shall be placed under
it at some future operation, which of course takes place upon the formation of each
distinct character. The apparatus is now stopped and ready for the formation
of the letter "T."
C
Upon depressing the key "T," see Figures 1 and 2, two inclined lugs 1 and 3 are
caused to actuate the rocking levers R2 and R3 and to therefore advance the push
rods or plungers P2 and P3, the first to the second position, and the second to the
fourth position so that the lateral extension of the pin P12 opposite the push
rod Pa is caused to assume the second position, or so that it will pass directly
under the curved lever 19 of the two-part lever 1, while the second plunger P³ is
given its extreme stroke, thereby placing the lateral extensions c upon the pin P
opposite this plunger in position to actuate the second acting lever 15 and stop
the mechanism at that point. The continued action of levers 18 and 19 causes a
dash impulse to be transmitted.
The next key "E" is now struck, but its key-lever L14 is provided with only
one inclined lug, to wit: lug No. 1 which imparts to that pin opposite the end
of push rod or plunger 13 an extreme stroke, thereby leaving that one of the lateral
extensions in front of the one thus moved to make a dot impulse when it passes
forward under the transmitter lever 18, the advance movement of the pin P
bringing it forward into position in line with the actuating lever as before.
The depression of the key "L" in the same manner imparts movement to three
push levers, to wit: P¹ P3 and P, so that two of the pins K¹ are placed in their
second position, while the third pin is placed with its lateral extension in the
stopping position as before, thus causing a dash of extreme length for the letter "L."
The key "E" is now depressed and forces forward a single pin to its extreme
limit which actuates the lever 15 as before so that a dot impulse is transmitted.
The key "G" is now depressed actuating three plungers, to wit: P2P and P,
the first two of which place the lateral extensions in the second position, while the
third placed the pin in the stopping position transmitting two dashes and one dot.
The key "R" is now depressed, causing two push rods to be actuated, to wit;
push rod P and push rod P5, but it will be observed that the lug which controls
push rod P2 is one of the No. 2 type of greater inclination than the lug of No. 3

page_text: type and less inclination than lug of No. 1 type, so that this push rod or plunger
places the pin P12 in such position that its lateral extension is out of the path
of the levers 18 and 19 and not sufficiently advanced to fall beneath the lever 15.
Consequently the first or single dot impulse is followed by a space and then two
dot impulses.
On depressing the key "A" two push rods or plungers are actuated, to wit; P3
and P, so that the first pin is caused to assume the first position and the second the
third position, thus transmitting a dot followed by a dash.
.
On depressing the key "M" three push rods or plungers are actuated, to
wit; P3, P4, and P5, two of which cause the proper pins to assume the second
position and the third the locking position transmitting two dashes.
As each key-lever is released, therefore, the power is intermittently applied to
the sprocket wheels SW and this intermittent action is dependent upon the
speed with which the operator actuates his key-lever, so that if he be very rapid
in his execution the transmitting chain will be advanced between the two sets
of sprocket wheels S¹ W¹, S2 W2, faster than it will be taken up by the constantly-
driven sprocket wheel S2 W2 inasmuch as this sprocket wheel derives its movement
from the spring action of the spiral spring SP, driven in turn by the intermittent
action of the applied power. Consequently, if the operator is rapid in his execution,
the chain may sag to a considerable distance between the two sets of sprocket.
wheels, but the transmission will be relatively constant, it being noted that as this
intermittent speed is increased there is consequently an increased storage of power
in the spring SP which will proportionately speed up the transmitting apparatus,
so that as the lateral extensions cc pass under the two arms 1819 of the yielding
lever they will transmit to line the successive current impulses of the nature
indicated and at a relatively constant speed.
Although the entire apparatus is hereinbefore described as a key-board trans-
mitter adapted to transmit Morse and analogous codes, it is understood that a
number of the parts thereof may be utilized for transmitting such codes with other
apparatus for controlling the same than a key-board.
As an
illustration of such use, the flexible transmitting chain with
its movable pins and lateral circuit controlling extensions may be used
either an an endless chain or any number of such chains may be used in connection
with electrical circuit controlling devices, such as are utilized generally in auto-
matic transmission, the characters to be transmitted having been set up or
established upon the chain either by hand or in any preferred manner. In other
words, such a flexible chain or device may be used to supplant the ordinary per-
forated or embossed transmitting filament used in connection with automatic
telegraphs, provided the electrical connections 'be arranged or adapted to suit such
use. Nor is the invention limited especially to a flexible medium or chain provided
with movable circuit controlling elements herein before described as lateral exten-
sions, as the same result might be effected with a cylindrical or disc surface
provided with sliding pins having such lateral circuit controlling extensions, and
their relative location for the transmission of a Morse code might be effected in a
manner which will readily suggest itself to those skilled in the art.

13. An automatic telegraphic transmitter, consisting of a series of movable circuit
closing contacts carried by a flexible chain and adapted, when located in alignment
with each other, to actuate a circuit closing device having two arms located in
different planes and carrying a contact point adapted to make contact with a stationary
contact located in an electrical circuit and in such manner as to transmit a con-
tinuous series of dot impulses, and when varied in accordance with a prearranged
order to transmit dash impulses or spaces between the elements of the character
itself or between all of said characters.
14. A key-board transmitter adapted to transmit Morse or analogous codes, con-
sisting of a series of rocking bars connected by levers to a series of push rods or
plungers, a series of key-levers provided with means so grouped as to actuate the
rocking bars in any desired order, in combination with a transmitting medium
provided with sliding pins having lateral circuit closing extensions, said pins being
adapted to be actuated by the aforesaid push rods or plungers, a circuit closing
device having two arms located in different planes and adapted to be actuated by
