HOWARD CRANMER, OF WICHITA FALLS, TEXAS.
ROUTE-INDICATOR.1,246,240.
Specification of Letters Patent.
Patented Nov. 13, 19-7.
Application filed April 7, 1916. -Serial-No.-89;564.
To all whom it may concern:
Be it known that I, HoWARD CrfANMER,
citizen of the United States, residing -att
Wichita Falls, in the county of Wichita and
5 State of Texas, have invented certain new
and useful Improvements in Route-Indicat-
ors, of which the following is a specifica-
tion.
My invention has relation to a. route indi-
10 cator for automobiles or the like and in such
connection it relates broadly to the provi-
sions of means whereby the tape, ribbon or
band constituting a road map or indicator
may from time to time operate an audible
35 signaling device to give notice to the driver
of approaching deviation or danger in the
road.
In traveling over strange roads it is of the
utmost importance, particularly at night,
20 that the turns, bends, crossings and other
hazards and dangers of the road shall :be
known to the driver some time before the
danger or hazard is to be met. In some
forms of route indicator a panoramic repre-
25 sentation of the road either in stationary or
rotary form is spread out before the driver.
However, such indicators are valueless with-
out the careful and close scrutiny of the
driver. Again as such panoramic guides are
30 usually of small size the signals or arbitrary
signs distinguishing the hazards are so small
and indistinct as to be confusing to the
driver, especially at night.
It is one of the main objects of my pres-
35 ent invention to provide a road map or in-
dicator which not only visibly indicates the
characteristics and risks of the road which
it depicts but is also provided with a means
for operating at required intervals an audi-
40 ble signal to call attention to approaching
hazards or dangers.
Another of the main objects of my present
invention is to provide means of simple yet
accurate construction whereby a traveling
45 apron band, tape or the like shall actuate
an audible alarm at times required.
In the carrying out of my invention there
is provided first,-a tape, band or apron hav-
ing on its face an indication or depiction
5D of the topography of the road and on its
body a series of apertures or openings so ar-
ranged as to control the operation of an au-
dible signal to call the attention of the
driver of the vehicle to an approaching haz-
55 ard or danger in the road; n scnd, thereis provided in conjunction with the band or
tape a. means for turning the same at a speed
corresponding with the speed of travel of
the vehicle and a means. for. establishing
through the apertures an electric circuit in 60
which a bell, buzzer or other audible signal
is included so as -to be operated when the
circuit 'is established.
The nature and -scope of my invention. will
be more fully understood from !the follow- 65
ing description taken -in connection with the
accompanying drawings forming part here-
of, in which-
Figure 1, is a top or plan view of a device
embodying the main features of my inven- 70
tion, the top or cover of the device being
partly removed.
Fig. 2, is a front elevational view thereof.
Fig. 3, is a side elevational view partly
sectioned. 75
Fig. 4, -is a longitudinal sectional view of
the device.
Fig. 5, is a rear view with .the cover plate
removed.
Fig. 6,is a cross sectional view taken on 80
the line 6-6 of Fig. 4.
Fig. 7, is. a longitudinal sectional view
taken on the line 7-7 of Fig. 6.
Fig. 8, is a detail view in section of the
driven spool or drum. .85
Fig. 9, is a detail view in section of the
guide rollers for the tape,, and
Fig. 10, is a face view of the tape.
Referring to the drawings, 1 represents
a casing .of required box shape and adapted 90
to be secured through ears 2 to the dash
board of the vehicle. Within the box or.cas-
ing 1 is located the various mechanisms for
driving the tape 3, reversing the movement
of said tape when required, rendering the 95
driving mechanism inoperative, the alarm
operating means and the illuminating means
together with the means for rendering the
alarm operating and illuminating means in-
operative. 100
All these mechanisms are carried by frame
work consisting essentially of a plate 4 and
such additional. standards, partitions, etc.,
as are required, especially such parts as will
be hereinafter described. 105
The plate 4 is connected to the front or
cover 5 of the box in such manner that when
the cover 5 is removed from the box, the
plate 4 and mechanisms supported thereby
may be withdrawn for adjustmeit or repairs no
