Miles to kilometers speed and distance indicators converter
First Claim
1. A converter to be connected between a vehicle transmission and a vehicle speedometer having a speedometer cable connected between the speedometer and the transmission by disconnectable couplings, the converter converting calibration of the speedometer between miles per hour and kilometers per hour, comprising:
- a housing having an annular wall joining two opposed end walls;
a first spindle entering the housing through a first end wall and supporting a first gear near the end of the spindle inside the housing;
a second spindle entering the housing through the second end wall and supporting a second gear near the end of the spindle inside the housing, the first and second gears having different numbers of teeth in the ratio of miles to kilometers;
first and second coupling means outside the housing and respectively surrounding the spindles and cooperative to receive said disconnectable couplings;
an idler gear journaled in the housing between the end walls and offset from said spindles, the idler gear meshing with said first and second gears; and
a partition in said housing extending between the first and second gears from the annular wall opposite the idler gear toward the idler gear, the partition having bearing holes therein respectively located opposite said spindles and supporting the inner ends of the spindles.

Abstract
This invention is a devise which when installed into its monitoring location in conjunction with vehicles transmission, shall increase the rotation of the speedometer cable and as a result, speedometer dials and odometers indicating speed and distance in miles shall automatically correct readings to be in kilometers without the changing or modifying in anyway existing vehicle speedometer dials. Removal of the devise, permits dials to again be read in miles. Installation and removal are very simple.
