Claims
- 1. An appliance for heating a food product that is impaled onto heating grills comprising:
- a plurality of heat conductive grills, each having an end for insertion into the food product;
- the plurality of grills mounted in an array and sized to be inserted as a group into the food product;
- a container for a liquid cooking medium;
- means for heating the cooking medium;
- a separator having elements sized to fit among the grills, the separator elements forming a resting surface for the food product;
- the separator and grills being relatively movable between a proximate position in which the separator elements are disposed among the grills such that the ends of the grills extend above the resting surface of the separator, and a non-proximate position in which the resting surface is disposed above the ends of the grills;
- first moving means for causing relative movement of the separator elements and grills from the non-proximate into the proximate position;
- second moving means for raising the container against the force of gravity from a lowered position into a raised cooking position for heating at least the grills such that heat passes from the grills into the food product for cooking the food product;
- the second moving means comprising means allowing the container to resume the lowered position;
- the first and second moving means comprising mechanical means responsive to the descent of the container into the lowered position to cause relative movement of the grills and separator from the proximate to the non-proximate position, said mechanical means using the weight of the container and cooking medium to provide the energy for said relative movement into the non-proximate position.
- 2. The apparatus of claim 1, the grills being fixed, the mechanical means lifting the separator against the force of gravity in response to the descent of the container into the lowered position.
- 3. The apparatus of claim 2, comprising separator actuation means, including the first moving means, for releasably retaining the separator in the non-proximate position and, upon the release thereof, for allowing the separator to descend under gravity into the proximate position.
- 4. The apparatus of claim 3 comprising:
- a press disposable above the grills for selective contact with a food product and for pushing the food product onto the grills so that the grills become imbedded within the food product;
- a press handle operatively connected to the press for causing movement of the press in response to movement of the handle; and
- separator actuation means responsive to motion of the press handle for releasing the separator actuation means when the press handle is moved in a direction for pressing a food product onto the grills.
- 5. The apparatus of claim 1, the grills being fixed, the mechanical means lifting the separator against the force of gravity in response to the descent of the container into the lowered position, further comprising:
- a rotatable member operatively connected to the separator, rotation of the rotatable member in opposite directions being effective to raise and lower the separator, respectively; and
- a retractable member adapted, when in an extended position, to push against a contact surface of the rotatable member for holding the separator in the non-proximate position, retraction of the retractable member from the extended position freeing the rotatable member and allowing the separator to descend.
- 6. The apparatus of claim 5, the retractable member being mounted on the container so that descent of the container with the retractable member in the extended position causes contact between the retractable member and the contact surface of the rotatable member, further descent of the container causing the retractable member to rotate the rotatable member and lift the separator.
- 7. The apparatus of claim 5, further comprising a press assembly for pushing the food product onto the grills so that the grills become imbedded within the food product and separator actuation means responsive to operation of the press assembly for retracting the retractable member.
- 8. The apparatus of claim 7, wherein the separator actuation means comprises a solenoid for retracting the retractable member, an electric switch, and means disposed on the press assembly for operating the switch upon operation of the press assembly.
- 9. The apparatus of claim 1, comprising:
- a member mounted for rotation about an axis;
- a support member responsive to rotation of the rotatable member for causing said relative movement of the grills and the separator; and
- a movable member mounted on the container for horizontal movement with respect to the container and for vertical movement with respect to the rotatable member upon vertical movement of the container, the movable member comprising means for contacting the rotatable member during descent of the container for causing relative movement of the grills and separator into the non-proximate position.
- 10. The apparatus of claim 9, further comprising means for moving the movable member horizontally out of contact with the rotatable member, thereby freeing the rotatable member for rotation and allowing the grills and separator to achieve the proximate position.
- 11. The apparatus of claim 10, comprising a cam member mounted on the container, a spring biasing the cam member, and cam moving means for selectively moving the cam member against the bias of the spring, the cam selectively moving the movable member out of contact with the rotatable member.
- 12. The apparatus of claim 1,
- the second moving means comprising a shaft mounted for rotation about an axis thereof, means for selectively rotating the shaft, and a container lifter mounted on the shaft and fixed against rotation with respect to the shaft, rotation of the shaft resulting in the lifting and lowering of the container,
- the apparatus further comprising a holding cam mounted on the shaft and fixed against rotation with respect to the shaft, and a pawl cooperating with the holding cam to retain the container in the elevated position when the shaft is rotated in a first direction.
- 13. The apparatus of claim 12, wherein the container lifter comprises a crank, and the means for selectively rotating the shaft includes means for selectively moving the crank.
- 14. The apparatus of claim 12, further comprising a shock absorber responsive to rotation of the shaft for slowing the descent of the container.
- 15. The apparatus of claim 12, further comprising:
- a timer;
- means responsive to operation of said second moving means for starting the timer; and
- a solenoid responsive to the timer for withdrawing the pawl from the holding cam a predetermined time following actuation of the timer.
