Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
179 words
A barbecue grill comprising a fire bowl for holding charcoal and the like, legs for supporting the fire bowl above the ground, a cooking grill above the fire bowl rotatable about a generally vertical axis, a single rod having a length greater than the diameter of the cooking grill selectively mountable in a generally horizontal position for use as a spit and in a generally vertical position for use in rotating the cooking grill on said vertical axis, a motor for turning the rod on its longitudinal axis, a first motor mount for removably mounting the motor in a position in which it is adapted to turn the rod when the latter is in its horizontal position, a second motor mount for removably mounting the motor in a position in which it is adapted to turn the rod when the latter is in its vertical position, and means for interconnecting the rod and cooking grill when the rod is in its vertical position whereby operation of the motor to turn the rod effects conjoint rotation of the cooking grill.
Claim 2
Dependent Claim
179 words
A barbecue grill comprising a fire bowl for holding charcoal and the like, legs for supporting the fire bowl above the ground, a cooking grill above the fire bowl rotatable about a generally vertical axis, a single rod having a length greater than the diameter of the cooking grill selectively mountable in a generally horizontal position for use as a spit and in a generally vertical position for use in rotating the cooking grill on said vertical axis, a motor for turning the rod on its longitudinal axis, a first motor mount for removably mounting the motor in a position in which it is adapted to turn the rod when the latter is in its horizontal position, a second motor mount for removably mounting the motor in a position in which it is adapted to turn the rod when the latter is in its vertical position, and means for interconnecting the rod and cooking grill when the rod is in its vertical position whereby operation of the motor to turn the rod effects conjoint rotation of the cooking grill.
