发明名称 Automotive service jack
摘要 A service jack includes a mirror attached to the jack's lift arm adjacent the jack's saddle so as to be able to provide a continuous reflected image for the jack operator as the lift arm is moved from its lowered position to its raised position of the sector of space above the saddle which includes a selected lift point for a vehicle being raised. A method for utilizing a service jack of this type includes the steps of positioning the jack with the lift arm in its lowered position adjacent the vehicle in the vicinity of the selected lift point, locating the selected lift point as a reflected image in the mirror, and moving the jack while elevating the lift arm so as to maintain the selected lift point as a reflected image in the mirror until the saddle engages the selected lift point.
