My invention relates to tape printing andpro
jecting apparatus, of a type sufficiently ‘repre
sented by a tape printer such as a stock ticker

' the objective and therefrom to the ‘correspond

beam passing through the other aperture'may go
directly to the corresponding objective and‘so t0
The principal object of the invention is to pro
vide for projecting a plurality, or speci?cally, as,

enced, such as ~sticking of the tape on the inter
mediate guide, improper direction of the tape by
rollers, stretching of the tape, etc.
25
The present invention‘ provides, as brie?y de
scribed, two substantially independent tape pull
ers, one of which acts on the tape at a point be
yond the ?rst aperture to advance the tape from
the't-icker and over said aperture, and the other
so‘ puller acts on the tape at a point beyond the sec
ond aperture to advance the tape over the last
named aperture. Between the apertures the tape
is reversed by forming in it a substantially free or
unsupported U-loop so that when, for example,
35 the printed face of the‘tape passing over the
' ?rst aperture is outward, the printed surface as
it passes over the second aperture .is downward
or inward in relation to the aperture and con
densing lens. The ?rst and second tape pullers.
40 are controlled by loops in the tape at proper
‘ .points in such manner that the reversing bend in‘
‘athe tape between the apertures is kept at proper
length and in proper'form without de?nite guid
ing or‘ support, except at points adjacent the
- 45 projector housing where the tape is engaged by
the feed rolls of one'puller. To provide for inde
pendent light beams through the apertures and to
the respective screens from a single light. source,
suitable lenses and re?ecting means are provided
50 to direct the beam from the lamp to and through
the apertures, and objectives and mirrors ‘are
arranged to direct portions of the beam from

pally the light apertures, and tape guiding, driv
ing and controlling means.‘

In Fig. l, I is a tape printer of the stock ticker
type and 2 designates the associated projector as
a whole. 'The projector includes a lamp housing IO cl

called a lens housing and in the top of this housing
are parallel light apertures 5 and 6 called for ‘con
venience the ?rst and secondaperture, each of _
a length corresponding to a desired 'length- or U
printed tape,
The ticker may be so arranged, as best shown
in Fig. _3, that the tape 1 goes directly (as viewed,‘
in plan) in a straight line and without transverse
twist or bend to the lens housing 4 so that a por
tion 8 of the tape passes over the ?rst aperture 5,
with its printed. face upward. _ At a point be
yond the ?rst aperture and beyond the housing
4 (at the right of Fig. 3) thetape is turned down
ward and at the same time directly laterally,
forming a U-bend 9; and after} passing through‘
this bend a portion ID of the time passes over the -
second aperture 6 with the printed face-down
ward. . The reversing bend 9, because of-the' guid
ing and driving means employed, may bev substan
tially free or unsupported._

The beam re?ected by mirror 63 passes through second light aperture 6. At a point beyond the
