This invention relates to new and useful im
provements in map devices.
More speci?cally the invention proposes a de
vice having a long transparent map adapted to
be wound from one spool to another, to be pro
jected for enlargement and to be synchronized
with a moving vehicle or conveyance so that the
same lineal distance is traversed on the map as

20. The rubber bushing lightly engages the adja
cent spindle ll, providing friction causing the
spool l8 to rotate slowly and preventing it from
moving except in response to the winding mech
anism later to be described.
A spool 2| is rotatably supported on spindle I?
in chamber l2. A ring gear 22 is secured to the
bottom face of the spool 2|. A casing 23 is se
