Abstract

A toaster for everyday household use includes a conveyor which carries items to be toasted past electrical heating panels. The toaster has an entrance wherein the items are inserted horizontally from a feed tray onto the conveyor. The feed tray being a cover for the entrance way, when the toaster is not in use, automatically opens to become a feed mechanism which closes after the item to be cooked has entered the toaster. The apparatus further has another door which functions as a cover for the exit hole of the toaster which automatically opens to dispense the cooked food item upon the end of a cooking cycle.

Claims

1. An electrical household toasting appliance comprising:

a conveyor for transporting food items through the appliance from an entrance to an exit;

a first tray member mounted by hinges from the entrance and which supports the food items as they enter the appliance;

a second tray member which is mounted by second hinges from the exit and supports the food items as they exit the appliance;

an electric motor assembly adapted for rotational communication with the conveyor;

a plurality of heating elements connected to an electrical supply; and

at least one mechanism for rotating at least one of the first and second tray members comprising;

a first electric motor; and

a first pivot linkage driven by the first electric motor.

2. The appliance as described in claim 1 wherein, the appliance further comprises:

a body, having a hinged door member having a translucent panel for viewing the food item, wherein a handle extends outwardly from a top portion of the translucent panel for manipulation of the door member thereof.

3. The appliance as described in claim 1 wherein the first pivot linkage comprises:

a first motor arm having two ends, one end mounted to the first electric motor, its other end mounted to a first link;

the first link being mounted to a first door arm, the first door arm being pivotally mounted by a first pivot pin to the appliance and further mounted to one of the first and second tray members.

4. The appliance of claim 1 further comprising:

a second electric motor; and

a second pivot linkage comprising;

a second motor arm having two ends, one end mounted to the second electric motor, its other end mounted to a second link;

the second link being mounted to a second door arm, the second door arm being pivotally mounted by a second pivot pin to the appliance and further mounted to the other of the first and second tray members.

5. The appliance as described in claim 4 wherein, the heating panels are displaced above and below passing food items for toasting opposing surfaces thereof.

6. An electrical household toasting appliance comprising:

a base member;

a body member fastened to said base member, said body member having a generally trapezoidal shape, a plurality of side walls and an entrance and an exit on opposite longitudinal ends thereof;

a conveyance assembly for transporting food items through said body member from said entrance to said exit at a speed;

a plurality of planar tray members each hinged at one end extending from each of said entrance and said exit;

a control means for adjusting said speed of said conveyance assembly;

a plurality of heating elements; and

at least one mechanism coupled to at least one of the plurality of tray members for rotating at least one of the tray members about its hinge comprising an electric motor and a pivot linkage.

7. The appliance of claim 6, further comprising a door member having hinged to said body member and having a translucent panel therein for viewing within the body member.

8. The appliance of claim 6, wherein said conveyance assembly comprises:

a electric motor assembly having an axle member extending crosswise of conveyor and adapted for rotation;

a plurality of chain linked segments extending along the longitudinal axis of the appliance;

a drive axle extending through the center of the chain linked segments being supported at one end by a first tab portion extending from the base member and supported and driven at an opposite end by the motor assembly;

a plurality of toothed sprockets, each being fixed to the drive axle and each being co-operable with one of the plurality of chain linked segments; and

a plurality of undriven axles each being supported at one end by a first tab portion and supported at a second end via a second tab portion.

9. The appliance of claim 6 wherein, the control means comprises:

a control panel disposed on said body having a plurality of switches, said control panel comprising means for setting the speed of the conveyance assembly and a timer.

10. The appliance of claim 6 wherein, the heating elements are located both above and below the conveyance assembly.

11. The appliance of claim 6 wherein the pivot linkage comprises an arm having two ends, one end mounted to the motor, its other end mounted to a link;

the link mounted to a door arm, the door arm pivotally mounted by a pivot pin to the appliance and further mounted to at least one of the planar tray members.

12. The appliance of claim 6 wherein, the control means for adjusting the speed of the conveyance assembly comprises a plurality of control buttons and a display.

13. The appliance as described in claim 12 wherein the plurality of planar tray members function as doors covering the entrance and exit of the appliance;

and wherein one of said plurality of control buttons functions to either open or close at least one of the planar tray members and wherein the display displays a greeting upon the opening of the at least one of the planar tray members.

14. The appliance of claim 13 wherein at least one of the control buttons regulates the speed of the conveyance assembly;

and wherein said display displays the amount of time the toaster is operational.

15. An electric household toasting appliance comprising:

a chain conveyor for transporting food items through the appliance from an entrance to an exit;

a first planar tray member having a handle, being mounted by hinges adjacent the entrance, which supports the food items as they enter the appliance;

a first mechanism for rotating the first planar tray member which comprises a first electric motor, a motor arm having two ends, mounted at one end to the motor and at the second end to the first planar tray member;

a second planer member having a handle, being mounted by hinges adjacent the exit which supports the food items as they leave the appliance, a second mechanism for rotating the second planar tray member which comprises a second electric motor, a second motor arm having two ends, the first end of the second motor arm being attached to the second electric motor and the second end of the second motor arm being attached to the second planar tray member;

a plurality of heating elements being disposed substantially parallel to the chain conveyor;

a translucent door having a handle being attached by at least one hinge to the appliance;

a controller operatively connected to the conveyor and the first and second motors for controlling the opening and closing of the first and second planar tray members.
