Abstract
Abstract A hotplate is which to serve foods upon, the device incorporating the advantages of a hotplate and a conventional lazy susan so that the food may be maintained in a heated condition and which can be conveniently brought into convenient proximity for a person to serve. The device comprising a selective heating coil selectively controlled in temperature by a manually regulated potentiometer, the base having an upstanding central post about which a Pyrex-type of plate is pivotable, the plate being dished with individual compartments into each of which a separate Pyrex plate of corresponding shape to the compartment is fitted and each one of which is adaptable for containing a specific food intended to be kept heated while upon a dining table.
