  • Patent number: 4726009
    Abstract: A leveling device and a method of use for record playing turntables to insure that the turntable is completely level around the entire periphery thereof. The leveling device comprises an outer housing having a peripheral section and with an opening in the housing to receive the spindle on the record playing turntable such that it is centrally located on and rests upon the turntable. The housing is provided with a peripheral section having a liquid therein and with the liquid depth being less than the depth of the peripheral section. In this way, the user can determine if the turntable is entirely level around its entire periphery by observing the liquid in the peripheral section of the device to determine if the device is level. If not, the user can make adjustments on the turntable to insure complete leveling thereof.
