Application filed Kay 8',
My invention relates to improvements in compass indicators for automobiles, etc, and itmore especially consists of the features pointed out in the claims.
The purpose of my invention is to provide a. direction indicating compass that is located in an inverted position above the driver; that enables the driver to read the compass indications on a mirror positioned in front of him which mirror is mech. :ically detached from the compass; that uses a reversed dial in the compass, nominally read able in the mirror; that uses a cooperating mirror placed on the steering column or the dash of the car; that utilizes the glass cover of the compass case as a jewel bearing for the compass needle when the inverted case is mounted'against the ceiling; and that combines an integrally formed casing with a contrasting dial in which the background is dark, the indications white, polished or luminous and the directing end of the needle is also white.
With these and other ends in view, I illus trate in the accompanying drawing such instances of adaptation as will disclose the broad underlying features of my invention without limiting myself to the specific details shown thereon and described herein.
