The mechanism by means of which the ticket
material is advanced from the supply roll to
and through the machine to the point of cut-off
to engage in the notches |3 in the tape to effect
will?rst be described, after which the mecha
nism for making impressions on the tape at
20 various points along its path of travel will be
explained in detail.
Referring to Fig. 4, the ticket tape I0 is fed
accurate alinement of the same. Pivoted to the
frame of the machine (see Fig. 1) is a pair of
?ngers 44 pivoted at 45 and provided with a pin
and slot connection 46 so that rotation of one
of the ?ngers will cause concurrent rotation in
from a spool II through an arcuate guide l2.
The tape is provided with notches I3 (as shown
25 in Figs. 16 and 17), disposed along the edges at
are provided with hooks 43 which are adapted
regularly spaced intervals, the distance between
the opposite direction of the other ?nger. When
the ?ngers are moved together, they will urge
hooks 43 into engagement with the edge of the
tape and when they are moved apart, the hooks

is at the point of cut-01f designated I8. This posi~
tion of the tape is also shown in Fig. 1 and in Fig.
21 the short vertical lines crossing the tape I0
35 indicate the limits of the successive tickets. With
the tape in the position of Fig. 21, printing of the
whose one arm carries a roller in engagement 30
with a cam 50 carried by shaft I4a. On the same
shaft is a cam 5| which cooperates with a fol

22. Thereafter, the ?ngers 4| are moved away
number” is printed at platen I6 on the .next fol
lowing ticket. Thereafter, the tape is moved. to
the position of Fig. 23 where the ticket is cut off
45
at the point I8. The mechanism for shifting the
tape to these various printing positions will now
be described in greater detail.
Referring to Figs. 6 and 9, a pulley I9 is driven
from any suitable source of power, such as an
50 electric motor (not shown), by means of a belt
20. Integral with the pulley is a clutch driving
element 2|, which, with the pulley, is loosely
mounted on shaft 22. When a ticket is to be
printed, clutch magnets 23 are energized to at
55 tract armature latch 24 and permit spring-pressed
dog 25, pivoted to arm'26, to engage the driving
element 2|. Arm 26 is secured to ‘the shaft 22
and, accordingly, the shaft will now be rotated.
As will be explained hereinafter in‘ connection
60 with the circuit diagram, the energization of the
magnet 23 is not maintained so that shortly after
energization it releases its armature latch 24, per
mitting the arm to drop back into the path of the
dog 25 so that upon completing a single revolution
65 of shaft 22, the parts become disengaged and re
sume their normal relationship, as in Fig. 9.
Referring now to Fig. 1, the shaft 22 carries a
bevel gear 21 meshing with a similar gear 28 on a
shaft 29 (see also Fig. 3). The shaft 29 carries a
70 gear 30, which meshes with a gear 3|, which in
turn causes operation of shafts |5a and Ma upon
which the lower printing wheels I5 and I4, re
spectively, are mounted through the medium of
gears generally designated 32. v Gear 3| also
75 drives a gear 33 which in turn, through the
destination,

operates to
notches I3
from the tape and returned to their initial posi
tion.
I
During the movement of the tape I0 toward the 45
left, under control of the ?ngers 4|, the tape is
free of the pairs of rollers I4 and I5. As is shown
in Fig. 21, the upper roller I4 is provided with
type on slightly more than half its circumference,
this type being arranged to e?ect the printing 50
shown in Fig. 16. The lower printing roller I5
carries the type for printing the face of the ticket
as in Fig. 17, with the exception of the variable
information. In Fig 21, the upper roller I4 and
the lower roller |5 have just advanced the tape 55
to “proper position for printing the destination and
at this time the raised type move out of engage
ment with the tape so that there is now no con
tact between the rollers. During the interval
that the type rotates from the position of Fig. 21 60
to that in Fig. 22, the classi?cation data are
printed and the tape is retracted to receive the
number and date printing, after which time the
type faces will arrive in the position of Fig. 22
and‘ again pick up the tape to advance it the 65
distance necessary to eject the completed ticket.
In Fig. 20 is shown a usual numbering device,
indicated generally at 53, which is reciprocal in
guides 54 and has the usual plunger 55 in engage
ment with a roller carried by a bell crank 56 70
which has link connection 51 with a follower arm
58 which is operated by a cam 59 carried on shaft
22 (see also Fig. 1). A similar cam 60, also car
ried on shaft 22, serves to» operate the dating de

vice which cooperates with platen IlI. At point
l8 there is provided a knife 6I (see Figs. 1 and 5)
which is pivoted at 62 and has connection with a
bell crank 63 which, in turn, is connected by a link
64 to a bell crank follower arm 65 operated by a
cam carried by shaft I511. At the proper time
in the cycle of operations, the knife GI is rocked
clockwise (as viewed in Fig. 5) to shear the com
pleted ticket from the following portion of the
10
tape.
Destination printing mechanism
Printing of the destination is effected on the
and link connection Ill to a follower arm 92 which
is operated by a cam 93 on shaft 22. The latches
84 are restored by-means of a bail 94 secured to
a shaft 95 which in Fig. 6 has lever and link con
nection 91 to a follower 98 which is operated by a
cam 99 also secured to shaft 22.
Price printing wheels
The price printing wheels 61 of Fig. '7 are loose
ly mounted on the shaft ‘Ill and are sector-shaped 10
as shown in Fig. 5, Integral with each sector til
is a pinion IIIIl which meshes with rack teeth in a
vertical link It I. The lower extremity of each
link IGI is also provided with rack teeth meshing

printing hammer 14 for each of the type wheels 6t
and one also for each of the type wheels 61. A
special hammer ‘Ila is provided for the type wheel
68 which differs from the hammer ‘ll in that it
40 has a longer striking face. ,All of the hammers
are freely pivoted at 15 and normally held in the

link 85 will trip the printing‘hammer as herein
above described so that stopping of the wheel and 45
tripping of the hammer are concurrent operations.
The reason for constructing the price printing
wheels'in the manner described and providing
mechanism therefor different from that for print
ing the destination is to enable an accumulation 50
to be made of the prices so that the total amount
of money involved in the several transactions may

through the train of gearing generally designated
‘I8 are ratchet-shaped driving wheels ‘IQ of which
there is one provided for each type wheel. In line
with each wheel ‘I9 is a, hook 80 pivoted at its up
per end to a lever BI and having its free end
spring-presssed against a by-pass latch 82 of a
pivoted member 83. The member 83 is spring
urged in a clockwise direction and normally held
against such movement by a latch at which has
link connection 85 with armature 85 of a magnet
8-1. Energization of magnet M will attract its ar
mature 88 drawing link 85 downwardly to rock
latch 84 counterclockwise‘and release lever $3.
The lever will thereupon rock hook at counter
clockwise about its pivot causing the tooth thereon
to move into the path of the teeth of the driving
ratchet ‘I9. The driving teeth will cause rapid
downward movement of hook 8t and through lever

of hook 86 its free end will strike the fixed cam-'
be accumulated. This accumulating mechanism
will be vdescribed later.
Classi?cation printing
55
The classi?cation wheel 68 (Fig. 8) is provided
with nine printing faces and as these faces are of
considerably greater length than the faces of the
type from which printing is effected in flight, it is 60
desirable that an impression be taken with the
.wheel at rest. For this reason, a form of Geneva
drive is provided which includes a star wheel EI'I
which is integral with Wheel 68 and both are free
ly mounted on the shaft ‘I0. Cooperating with the 65
wheel II'l is a driving pin I I8 carried by an arm
ming surface 88 and will disengage it from the
M9 on a rod I20.
driving wheel ‘l9.
carries a pinion IZI (see Fig. 6) Which meshes
with a. gear I22 driven from the chain of gearing
18 so that the wheel ii?-advances constantly with 70
a step-by-step movement as the destination
wheels 69 advance with a continuous movement.
The printing hammer ‘Ma for the wheel 63 is
tripped in exactly the same manner as the ham
mers ‘Ill and the timing is arranged so that the 75

The particular character to be printed from any
wheel is determined by the timing of the operation
of the printing hammers ‘It and the circuits and
mechanism for effecting this timing will be ex
plained in connection with the circuit diagram.
The levers 83 are restored by means of a bail 89

40 tending into each notch is a cam latch I45 against
brushes I59 is provided to connect the segments
which the operated key lever acts to cause the
plate I43 to be shifted toward the left as viewed
in Fig. 10. The plate has connection with a link
I46 which is provided with an extension I41 (see
45
also Fig. 12) which operates a pair of contacts
I48. As the plate I43 is moved toward the left
as a consequence of the operation of one of the
key levers, the extension I41 will close contacts
I48. These contacts control the initiation of. a
50 cycle of operations of the machine during which
the ticket is prepared and ejected. Secured to
each of the bars_I31 is a plurality of contact
plates I50 which are suitably insulated from one
another and from the bar I31 (see Fig. 11) .
The
55 number of plates I50 connected to each bar I31 is
dependent upon the number of letters in the
destination and the number of ?gures in the
price to be printed under control of the related
key. For example, the bar I31 associated with
60
the “Albany” key has plates I50 secured thereto
which are separately shown in Fig. 18.
The left
hand plate will control the printing of the desig
nation “One way”; the next six plates will control
the printing of the destination “Albany”; the
65
next one will control the printing of the dollar
sign; and the last three will control the printing
of the digits of the amount. Each of the plates
I50 has a pair of steps I5I located at various
70 levels in accordance with the character to be'
printed. These steps are arranged, when the
supporting bar I31 is lowered, to complete elec
trical connections to the printing magnets to
select the various characters at the proper time
75 in the operation of the machine. Extending
I51 in succession with the common conductor I 58
of. one set and a brush I59A e?ects similar con
nection between the second set and its common
conductor I58.
These brushes are carried by 45
and insulated from an arm I 60 carried by a shaft
22. The timing of the operation is such that the
brushes I59A and I59B make contact with the
segments successively as the type on the various
printing wheels arrive at the printing line in the 50
order designated in Fig. 19 opposite the springs
I52. The tracing of a speci?c circuit will make
this clear.
With the plates I50 making electrical connec
tion between the sets of springs I52 as shown, a 55
circuit will be completed when the brush I59A
contacts the ?rst segment I51, which is traceable
as follows: from the negative side of line IGI, to
left hand conductor I58, brush I59A, uppermost
segment I51, wire I56, socket I54, to the left 60
hand plate I50, thence to the uppermost spring
I52 and the uppermost printing magnet 81
through a wire I62, cam controlled contacts I63,
to positive side of line. I64.
This circuit is com
pleted as the classi?cation wheel 68 presents the 65
designation “One way” to the printing line and
this designation will be printed on the ticket. A
second circuit is also completed concurrently
which extends from the uppermost wire I 52, to
the second plate I50, the second spring I52, to 70
the second printing magnet 81, a wire I65, a pair
of cam controlled contacts I66, to line I64. The
parts are so timed that the type element for
printing the letter “A” is at the printing line at
this time and the. character “A” will consequently‘ 75

When the brush has advanced to the second seg

near. the end of the cycle of operations so that
the parts may return to their normal position. 5
A hand lever‘I10 is provided (Fig. 6) which lies
ment I51, a circuit is completed to print the let
ter “B” in its proper position on the ticket. In
10 this manner, as the brushes I59A and I59B ad
vance, the characters will be printed in the or
der in which they are connected to the springs
over a pin MI in lever I61 so that the-same may
be operated manuall . A units counter I12 is
to the link I08 so that each operation of the 10
machine may be counted and, since for each
operation a ticket must be issued,'the counter in
I52; thus, the digits 3, 4, and 5 of the price will
be printed next, and the “L” and “N” in order,
15 and near the end of the cycle, the letter “Y” will
be printed, followed by the printing of the dollar
sign. In a single revolution of the printing
wheels, therefore, the various characters will be
printed as they pass through the printing posi
20 tion.
_
Iteferring now' to Fig. 15, wherein a section of
the type wheel group is shown, it will be ob
served that alternate ones of the wheels 69 are
displaced a half step with respect to the rest of
25 the wheels.
'
to avoid so-called'
shadow printing, that is, the printing of adjacent
portions of characters from the adjoining type
wheels together with the printing of the selected
character, and permits the use of the largest
30 possible characters in a smaller space. In order
to print correctly from these offset type, it is‘
necessary to delay the timing of the wheels whose
characters are set back a half step an equivalent
' amount, and it is for this reason that the two
35 emitter brushes I59A and I59B are provided.
The brush I59A controls the completion of cir
cuits through the classi?cation and amount print

Referring to Fig. 19, the closure of contacts
15
I48 due to the operation of one of the key levers
I34 will complete a circuit from line I66, con
tacts I56, a relay I16, to line I6I. The relay
closes its contacts I14a which completes the cir
clutch magnet 23 and 20 '}
cycle of
operations in the machine, toward the end of
which the contacts I68 are mechanically un
latched to permit theirlopening and interruption
of the operation after a complete cycle has been 25
effected.
Accumulating mechanism
_
.
The accumulating mechanism is shown in Figs.
5, 5a and 5b and comprises a plurality of print- 30
ing wheels I15 to which gears I16 areattached.
The wheels and gears are mounted on a rod I11
carried in a frame I18 which is pivoted at I19
and has a rod I80 passing through a slot I6I in
an arm I82 secured to a rod I83. When the arm 35
I82 is rocked clockwise, the slot I8I will cause
the member I18 to rock counterclockwise and
withdraw the gears I16 from engagement with
type wheels when counted from the left in Fig.
40 15. These are the printing magnets which are
the teeth in sectors I84. The operation is such
that as the sectors I03 are rocked clockwise to 40

In the diagram of Fig. 19, the brushes I59A
and i593 are shown as being of the same length
and their related segments I51 are offset a half
.
In the actual construction, for purposes
70 of uniformity, the segments of the two sets are
actually side by side, but the brushes I59B (see
Fig. 5) are adjusted to make contact a half
step later than the brushes I59A.
Referring to Fig. 6, the shaft 90 has secured
75 thereto an arm I61 which, through a link I68,
rod I63 to a follower arm I9I.
The roller is op
erated by a cam I92 carried by the shaft 22.
After each entry into the wheels I15, a printing 65
hammer I93 (Fig. 5) is tripped to take an im
pression from the wheels onto a record strip I96
which is provided with suitable spacing mecha
nism (not shown). Hammer I93 is carried on a
rod I95 (see Figs. 5a and 5b) to which is also se- 70
cured a member I96 which is connected by a link
I91 to an arm I98 secured to a rod I99. In
Fig. 6 the rod‘ has link and lever connection 200
