7 Claims.
This invention relates in general to machines
for co-operating with record receiving tapes such
as ticker tape, and more especially to machines
for co—operating with endless tapes or ?lms.
One of the objects of the present invention is
to provide a machine co-operating with record
receiving tapes such as ticker tape, and more
especially with an endless tape, ?lm or the like,
whereby the tape may be passed through a stock
10 ticker or the like for receiving printed matter
such as stock quotations and the like, and the
tape then passed through a bath for removing the
printed matter, and ?nally treating the tape to
prepare it to be returned to the printing machine
15 or stock ticker.
Speci?cally this invention contemplates the
provision of a machine co-operating with an end
less tape, composed of a transparent material
such as celluloid, cellophane or the like, whereby
20 a portion of the tape may ?rst receive printed
matter, then have this printed matter projected,
and ?nally have the printed matter removed.
These and other features, capabilities and ad
vantages of the invention will appear from the
25 subjoined detail description of one speci?c em
bodiment thereof, illustrated in the accompany
(Cl. 88-—24)
standards 5 and 6, which support beneath the
platform 4 an elongated trough member ‘I having
a bath chamber 8 at one end and an elongated
heating chamber 9 at the other end.
In the course of operation, the tape, in the pres
ent instance, an endless tape is mounted to travel
from the ticker 3, where it receives printed mat
ter, to the projecting machine I where the printed
matter is projected and then the tape passes to a
suitable ink removing means in the present 10
instance, the bath chamber 8 where the printed
matter is dissolved and washed off, whereupon
the tape passes to the heating chamber 9 where
the tape is dried to prepare itfor again receiving
printed matter in the ticker.
The liquid in the bath chamber 8 may consist of
carbon tetra-chloride or any other ink dissolvent,
depending upon the ink being used on the tape.
For guiding the tape in its cycle aforesaid, the
ticker is provided with the usual guide roller II],
which may also be the drive roller, from which
the tape passes to the rollers H and I2, indi
cated in a general way as the printing mecha
nism, after which the tape with its printed matter
facing upward is bent a complete ninety (90°) ‘de

Of course, in some instances, both faces of the

the bends 26 and I‘! of the tape turn in the same 55
ing drawing, in which
direction so that the surface of the tape receiv
ing the impression 50 in the ticker 3 will be fac
ing upwardly when it passes out of the pro—
jecting machine and will again face upwardly
when it leaves the bath and thus be in position
to be engaged and treated by the buffer 21.
After the tape has passed around the guide
roller I9 in the bath chamber 8, and before it
passes the guide roller 20, it will pass between
10 two pads 28 and 29, engaging opposite faces of
the tape and exercising pressure on the tape
while it passes through the bath. With such
pressure, these pads 28 and 29 will function as
wipers and wipe the ink dissolved on the tape
from the same. As the tape leaves the guide
roller 20, and before it passes to the guide roller
2|, it is again passed between two pads 30 and
3| which are positioned above and out of the
bath chamber 8. The pads 30 and 3| serve fur
ther to wipe and clean the tape of any ink which
may still appear on the same.
From the guide roller 2|, and before‘it reaches
the guide roller 22, the tape will pass between
the buffer 21 and the roller 32 disposed therebe
neath, such buffer 21 and roller 32 exercising
pressure on the tape in opposite directions.
The buffer 21 is connected, in Fig. 3, to the
motor 33 and the roller 32 is operably connected
with the drive shaft 34 on which the buffer 21
is mounted by means of the reduction gears 35,
36 and 31, in mesh with one another. The gear
31 is mounted on the shaft 38 to which the roller
32 is ?xed, and the gear 35 is mounted on ‘the
shaft 34. The roller 32 rotates at a much lower
speed than the buffer 21 in order to retard the
movement of the tape relative to the speed im
parted to it by the buffer 21 so as to co-operate
with the buffer 21 to perform a bui?ng action on
the tape 2.
Above the buffer 21, there is positioned a drip
ping nozzle 39, which is connected with a reser
voir 49, to supply a slight amount of moisture or
liquid solution to the buffer 21 in order to dis
solve any ink that may still remain on the tape
that may have dried thereon in streaks.
The buffer 21 rotating at a higher velocity than
the roller 32 ‘will serve to dissolve and wipe off
such remaining ink on the tape.
After the tape leaves the buffer 21, and before
it passes over the guide roller 22, it will pass
under another wiping pad 4|, which serves as an
auxiliary pad to further wipe off the tape.
The heating chamber 9-is enclosed as shown by
the cover member 42, through which the slots
55 43 and 44 are formed, the slot 43 serving as an
ductors 46 and 41. Thus obviously as the
solenoid 5| is energized whenever a message is
transmitted, the armature of the solenoid 5|
will serve as a switch to close the current
and cause the motor 33 to operate. Obvious
ly also when the transmission of the mes
sage ceases, the solenoid will be de-energized
releasing the armature and thus breaking the
thus produced switch of the motor. With the
foregoing arrangement, therefore, the electrical
circuit leading to the motor 33 is closed by the
solenoid 5| every time the ticker operates so that
electrical energy flows to and actuates the motor
33. The motor starts up gradually due to the fact
that it must overcome its own inertia as well as
the resistance of the attached load (tape, pulleys,
etc.) which it is driving. After the motor reaches
its normal operating speed, it continues running
at such speed until the ticker stops printing im 20
pressions on the tape when the solenoid 5| is
de-energized and the motor circuit is opened.
When the motor circuit is opened, the electrical
energy ?owing to the motor is cut off and the
motor gradually stops. In this manner, the
jerky step by step motion of the tape as it leaves
the ticker is converted into a relatively smooth
motion so that the tape when passing through
the projecting path during the starting and
stopping of the motor starts and stops gradually.
With the present invention, when it is desired
to use an endless perforated ?lm strip 48, such
as illustrated in Fig. 4, the various guide rollers
l0, |8, I9, 20, 2|, 22, 23 and 24 will preferably
be formed like the roller 49 illustrated in Fig. 4,
with prongs or teeth 52.
It is obvious that various changes and modifi
cations may be made to the details of construc
tion without departing from the general spirit
of the invention, as set forth in the appended 40
I claim:
1. The combination with a stock ticker, of a
projecting machine, ink removing means, heating
means, an endless tape, and feeding means for
feeding said tape successively to cooperate with
the ticker, a projecting machine, ink removing
means and heating means to receive printed mat
ter, project the same, remove the printed matter,
dry the tape by the heating means, and then re- _
turn to the ticker for another cycle of opera
2. The combination with a printing mechanism,
of a bath, a heat containing chamber, an endless
tape, feeding means for repeatedly feeding said
opening for the tape 2 to enter the heating cham
endless tape from said printing mechanism
her 9, and the slot 44 serving as an opening for
through said bath and through said heat con
the tape 2 to leave the heating chamber 9.
For heating the chamber 9 any suitable heating
taining chamber, back to said printing mecha
nism, and guide rollers for guiding said tape while
60 means may be used, such, for instance, as hot
air introduced into the heating chamber 9
through the nozzle 45.
As is usual with stock tickers, the tape is only
operated and driven when a message is trans
- mitted across the wire to operate the printing
mechanism, that is, the tape is advanced an in
terval of distance after each printing impression
or after completing a line of printed matter as
is the case with sporting news tickers. There

it is being fed by said feeding means.
3. The combination with a printing mechanism,
of a bath, a heat containing housing, there being
two slots in said heat containing housing, an end
less tape, feed mechanism for actuating said end
less tape, and guide rollers for guiding said tape
from said printing mechanism through said bath
into the heat containing housing through one of
the slots of the housing, and out of the heat con
taining housing through the other slot thereof,
back to the printing mechanism for repeat use.’ 70
4. The combination with a printing mechanism,
of a bath, a heat containing housing, there being
two slots in said heat containing housing, an end
less tape, feed mechanism for actuating said end
less tape, and guide rollers for guiding said tape 75
from said printing mechanism through said bath
into the heat containing housing through one of
the slots of the housing, and out of the heat con
6. The combination with an endless band, of a
light aperture, ink removing means, a band draw
ing means for drawing the band across said light
taining housing through the other slot thereof,
aperture then through said ink removing means,
back to the printing mechanism, and pads in en
gagement with said tape while it passes through
said bath and as it passes from said bath to said
heat containing housing to remove the ink on the
an electric motor for actuating said band draw
ing means, an electric switch, and means in
cluding a ticker for drawing the band from said
ink removing means toward said ticker and con
trolling the electric switch in turn to control the
tape dissolved'by the bath.
5. The combination with stock quotation,
printing and projecting mechanisms, of an end
less ticker tape carried by said mechanism to pass
successively and repeatedly through the printing
and projecting mechanisms, and means operat
15 ing on the tape subsequent to its passage through
the projecting mechanism and prior to its passage
through the printing mechanism for removing the
matter imprinted on said tape, said printing and
projecting mechanism and the ink removing
means being positioned close together whereby
the length of tape required is reduced to a mini
actuation of said motor.
7. The combination with an endless band, of a
printing mechanism adapted to print upon said
band and issue the band as it is printed, a com
bined drawing and bu?ing roller for drawing the
band through said projecting machine and simul
taneously cleaning the same, an electric motor
to actuate said drawing means, and a switch for
shutting o? the current of said motor when said
printing mechanism stops.
