Abstract
Abstract A cooking apparatus is provided comprising a hopper for storing raw or precooked foodstuffs; metering means constructed and arranged to meter by weight a predetermined quantity of foodstuffs received from the hopper, a vibratory conveyor operable to promote the movement of foodstuffs from the hopper to the metering means by gravity; a cooking medium; and a cooking container displaceable between a first position in which the container receives foodstuffs from the metering means, a second position in which the foodstuffs in the cooking container are placed in the cooking medium and a third position in which the foodstuffs may be dispensed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
190 words
Apparatus for cooking foodstuffs comprising: a gravity hopper for storing and discharging raw or precooked foodstuffs; metering means positioned lower than said hopper for metering a predetermined quantity of the foodstuffs received from the hopper; conveyor means operatively connected between said hopper and said metering means comprising a generally downwardly sloping walled ramp, for conveying said foodstuffs under force of gravity from said hopper to said metering means; vibrator means operatively associated with said conveyor means, for assisting the downward movement of the foodstuffs; a vat for holding a cooking medium, positioned lower than said metering means; and a cooking container displaceably positioned between said metering means and said vat, which is continuously cyclically displaceable between a first position in which said container receives foodstuffs from said metering means, a second position in which the foodstuffs move under force of gravity to a cooking part of said container and said cooking part is placed within said vat, and a third position in which the cooking part is removed from the vat and the foodstuffs move under force of gravity to a delivery part of said cooking container and are discharged.
Claim 2
Dependent Claim
190 words
Apparatus for cooking foodstuffs comprising: a gravity hopper for storing and discharging raw or precooked foodstuffs; metering means positioned lower than said hopper for metering a predetermined quantity of the foodstuffs received from the hopper; conveyor means operatively connected between said hopper and said metering means comprising a generally downwardly sloping walled ramp, for conveying said foodstuffs under force of gravity from said hopper to said metering means; vibrator means operatively associated with said conveyor means, for assisting the downward movement of the foodstuffs; a vat for holding a cooking medium, positioned lower than said metering means; and a cooking container displaceably positioned between said metering means and said vat, which is continuously cyclically displaceable between a first position in which said container receives foodstuffs from said metering means, a second position in which the foodstuffs move under force of gravity to a cooking part of said container and said cooking part is placed within said vat, and a third position in which the cooking part is removed from the vat and the foodstuffs move under force of gravity to a delivery part of said cooking container and are discharged.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 wherein said metering means is weight responsive and includes a counterbalanced pivotable arm having a foodstuff receiver on one side of its pivot axis and an adjustable weight on the other side.
Claim 4
Dependent Claim
26 words
The apparatus of claim 2 wherein said foodstuff receiver includes an openable wall section and means for biasing said wall section to a normally closed position.
Claim 5
Dependent Claim
43 words
The apparatus of claim 3 further including a power-operated linkage means for simultaneously opening the openable wall section of the foodstuff receiver of said metering means and displacing said cooking container from its third or discharging position to its first or receiving position.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 wherein a horizontal ramp section is provided on the lower end of the conveyor means.
Claim 7
Dependent Claim
21 words
The apparatus of claim 1 or 5 wherein said vibrator means comprises an electromagnet powered by a pulsating D.C. power source.
Claim 8
Dependent Claim
13 words
The apparatus of claim 6 wherein said conveyor means is supported on springs.
Claim 9
Dependent Claim
29 words
The apparatus of claim 7 wherein the pulsating frequency of said D.C. power source is substantially equal to the natural mechanical resonance frequency of said conveyor means and springs.
Claim 10
Dependent Claim
15 words
The apparatus of claim 8 wherein the vibration of said conveyor means is amplitude modulated.
Claim 11
Dependent Claim
24 words
The apparatus of claim 1 wherein said cooking container is pivotally mounted on a pivot axis, which axis is slidable along a notional line.
Claim 12
Dependent Claim
44 words
The apparatus of claim 10 wherein said pivot axis when said cooking container is in its first position is at a point along said notional line between the points of the pivot axis when the cooking container is in its second and third positions.
Claim 13
Dependent Claim
54 words
The apparatus of claim 1 further including dispenser container means comprising: means for holding a stack of cups; means for removing a cup from said stack; and means for positioning said cup beneath said cooking container delivery part when said cooking container is in its third position, so as to receive cooked foodstuffs therefrom.
