gage this movement of the slide the handle
52 operates between two stops or projec-
tions 53 carried by bracket 54 pivoted on
shaft 51 which through screw 55 passing
5 through a slot 56 of bracket 54 may be
adjustably secured to cover 5. When, how-
ever, the tape is used to indicate a return
route, the pins or stops 53 are adjusted to
permit of the proper movement of the slide
10 under the new conditions. This is accom-
plished by unloosening the screw 55 and
turning the bracket 54 to the required posi-
tion. The cover 5 has marks to indicate the
required position of stop bracket 54.
15 The plate 42 maintains electrical contact
with one pole 57 of the buzzer or electric
alarm 431 during its shifting operations by
preferably the means disclosed in the draw-
i ngsnamely-the pole 57 of buzzer 43a is
20 extended in the form of a contact spring 58
normally pressing upward in contact with
the under surface of the plate 42.
For night use, a small electric lamp 59
is installed to the rear of the tape 3 as it
25 passes over the window or opening 34 of
the cover plate 5. Any means for conduct-
ing current from the two binding posts 38
and 43 to and through the lamp 59 may
be devised, and any means for making and
30 breaking the circuit through the lamp
would be within the scope of my invention.
For the sake of illustration the drawings
show the lamp 59 screwed into a metallic
socket 60 connected to a plate 61 having a
35 contact piece 62 and its base fits against
the plate 36. A contact spring 63 carried
by a slide 64 and button 65 serves to make
or break contact between plates 61 and 36
by sliding over or away from the piece 62
40 and a piece 66 leading by wire 67 to the
binding post 43.
To permit of the easy removal and re-
placement of tape 3 between central roller
28 and the rollers 29 and 30, these outside
4:5 rollers 29 and 30 are each supported by
levers 68 and 69 pivoted at one end to the
bed plate 4 so that the rollers 29 and 30
may be swung toward or away from the
central roller 28. A screw post 70 serves
50 to. clamp or lock the free ends of levers 68
and 69 when rollers 29 and 30 are properly
adjusted.
When a return trip of the road or travel
in a reverse direction is to be indicated by
55 tape 3, the reel of tape on spool 7 and the
reel of tape on spool 9 are removed and
tape turned over with the two reels placed
on respectively spool 9 and spool 7. In
other words after the tape is turned overthe wound up portion of the tape is placed 60
on idle spool 9 and the unwound portion
on driven spool 7.
Having thus described the nature and
objects of my invention what I claim as
new and desire to secure by Letters Pat- 65
ent, is-
1. In a device of the character described,
the combination of a driven reel and an
idle reel, a tape arranged to be wound upon
the driven reel and unwound from the idle 70
reel, two friction rollers geared together
and positively driven, between which rollers
the tape is arranged to pass, an idle fric-
tion roller adjacent to one of said driven
friction rollers between which and said 75
driven friction roller the tape is arranged
to pass and two contact posts over which
the tape is moved in its passage from the
two driven friction rollers to the driven
and idle friction rollers. 80
2. In a device of the character described,
a driven reel controlling the movement of
the tape and means for positively actuating
said reel, in combination with a resetting
device comprising a shaft arranged to be 85
drawn outwardly and pushed inwardly of
the device, a. pinion and worm gear on said
shaft adapted to mesh with the actuating
mechanism for the reel when.said shaft is
pushed inward, a pinion on said reel and 90.
a second pinion in gear therewith, said
second pinion adapted to mesh with the
worm gear on said shaft when the shaft is
drawn outward to disengage the pinion and
worm gears from the actuating mechanism 95
for the reel, and means on the shaft for per-
mitting of the manual shifting in and out
of said shaft.
3. In a device of the character described,
a driven reel, a spindle carrying said reel, 100
a ratchet wheel loose on said spindle, a
pinion rigidly connected with the ratchet
wheel, said pinion being in mesh with the
means for driving the reel, a pawl pivoted
to the reel and engaging the teeth of the 105
ratchet wheel and a spring locked to the
reel and arranged to yieldingly press said
pawl against the teeth of said ratchet wheel.
4. In a device of the character described,
a positively actuated tape, two contact posts 110
over which the tape is moved, two contact
springs, a common plate from which said
springs project and means for shifting said
plate to bring either of said springs in con-
tact with its respective contact post. 115
In testimony whereof I have signed my
name to this specification.
