As shown in Figures 2 and 3, the top section 22 allows a person to view the food supply in a storage hopper 24 that is mounted within the housing 12. The bottom of the hopper 24 is in open communication with a hopper feed chute 26 of a modular dispenser unit 38. The chute 26 is mounted on a top plate 28 which in turn is mounted by elongated bolts 30 and wing nuts 31 to a bottom plate 32.
,~ The bottom plate 32 has a discharge chute 34 depending ', therefrom. The top plate 28 and bottom plate 32 are spaced apart to form space 29 and rotor or carousel assembly 36 interposed therebetween.
, A motor assembly 42 is also mounted to the ,, underside of bottom plate 32 and is operably connected to the carousel assembly 36.
The carousel assembly 36, top plate 28, bottom i; plate 32, feed chute 26 and discharge chute 34 and motor 42 ',; form the dispenser unit 38 which dispenses a portion of '~ food from hopper 24 to a discharge funnel 40 mounted under ,. .~
J chute 34. The funnel 40 leads to the discharge opening 16 in the front panel 14.
Referring now to Figures 4 and 5, the dispenser ~;;,.
unit 38 has an aperture 44 through its top plate 28 aligned with the bottom of the hopper chute 26. The bottom plate 32 has an opening 46 misaligned with the aperture 44.
. . . .
The positions of the aperture 44 and opening 46 can be most t,',, easily defined with respect to the drive shaft 48 connected !,~
~, to the motor assembly 42 which is vertically mounted at j the center of the two plates. The aperture 44 and opening :

46 are the same radial distance from shaft 48 and circumferentially spaced 1800 apart.
As shown in Figure 3, 6 and 8, the bottom plate 32 has a trap door 70 which is aligned directly under ~-. 5 aperture 44 and when open communicates with a secondary :, ,- discharge chute 72 which extends to the back panel 74 which .
.~ has an access door 76. The bacX panel 74 can also be provided with air vents 77.
.The carousel assembly 36 includes two spaced ,~I 10 apart mesh screens 50 which act as two opposing side walls .,j,,.
;and two other opposing solid side walls 52. The screens so and walls 52 define a container 53. The container 53 has ~:an open bottom 54 and an open top 56. The open top 56 is ~,aligned with an opening 58 in a closing plate 60 which is ,, ~:
mounted adjacent to and under the top plate 28. The one edge of the opening 58 in closing plate 60 has a canted '~flange 59.
The solid side walls 52 extend substantially the whole length of the top and bottom plate beyond the mesh '20 screens 50. The bottom edges of the side walls 52 are mounted onto a drive plate 64 which radially extends from drive shaft 48. The drive shaft 48 turns the drive plate 64 which in turn rotates the carousel assembly 36 about the drive shaft 48. The drive plate 64 has a magnet 65 mounted ~t25 thereon. The underside of the bottom plate 32 has two ~:;imagnetic reed switches 73 and 75 which interact with magnet i;:,l .
I~ 65.
~!
A heating gun 66 has a heating coil assembly 68 ~,~in the form of a nozzle pointed to the space 29 between the ~.' , ' :

r,. ' " ~ ' , ' ~' ~ . ' ' ' ' ' ' ' , ' ' : ' ' wosl/l5l44 PCT/US91/02273 2n~9~ 8 -plates. The gun 66 also has a separate ~lower 69 upstream from nozzle 68. The bottom plate 32 has an upward vent deflector section 33 which deflects the heated air to prevent it from directly hitting side panel 15.
A control panel 79 is operably connected to the reed switches 73,75, coin mechanism 20, lights 18, switches 19, heater gun 66, blower 69 and drive motor 42 via electrical wire 78, 80, 82, 84, 86 and so. The control panel 79 may be of any well known mechanical, electromechanical or electronic mechanism such as a printed circuit board and can be programmed in known manner to control and operate dispenser unit 38 in a programmed sequence.
In operation, the hopper 24 is filled with the food to be dispensed such ~s cashews, peanuts, or sunflower seeds. For this purpose the top section 22 can be opened ; to allow food supplies to be loaded into the hopper 24.
In the stand-by position the container 53 is opposite the heat gun 66 and between the supply chute aperture 44 and discharge opening 46. Upon the input of the appropriate coinage in the mechanism 20, the control panel 79 actuates the drive motor 42 which rotates the motor 42 which starts to rotate the basket assembly 36.
The carousel assembly rotates about drive shaft 48. When the opening S8 rotates under the aperture 44, a portion of , food in hopper 24 falls into the container 53 and rests on 7 bottom plate 32. As the carousel assembly 36 continues to rotate about shaft 48, the flange 59 pushes up any food ; supply out of the way as the opening 58 in the closing . . . .
WO91/15144 PCT/US9~/02273 ~ 2 ~ 6 plate 60 becomes misaligned with the aperture 44 to prevent wedging of food between the two plates 28 and 60.
Simultaneously as the carousel 36 starts to rotate the control panel also powers up the heater gun 66 and turns on one of the lights 18a which has an appropriate legend to instruct the operat~r to get a cup or bag. The carousel assembly 36 continues to rotate sliding the food on plate 32 until the magnetic reed 73 switch 75 is actuated by the magnet 65 on the drive plate 64 at which time the control panel deactuates the motor 42.
Alternatively, a predetermined delay can be introduced before the motor stops.
The carousel assembly and bottom plate 32 and top plate 28 create a tubular channel through which the heated air from the heat gun 66 as shown in Figure 7 can be channeled through the transverse mesh screens 50 to heat , the food that fell into the container 53. The air flow ~: through the channel, deflects upward on Section 33 and passes out through vents 77.
~, 20 The heating continues for a period of time , determined by the control panel. The time the heat gun 66 is actuated is variable. The control panel 79 can take into account the internal temperature within the carousel assembly before the coins actuated the vending machine cycle. During this heating sequence the controller actuates one of the lights 18b which has an appropriate legend such as "Place Cup Under Chute." At the end of the i' predetermined heating time the heater coil assembly 68 is , turned off. The blower 69 of the heat gun 66 can continue ;
~ :, ' ' " ' ' "" , ' , : ' ~ ' ' ' WOs~/151~ PCT/US91/02273 2~17~8~ lo ~
for a few seconds to cool the coil assembly 68 and then it also is turned off. One of the lights 18c flashes ~o properly instruct the operator to ~Press When Ready.
Light 18c is incorporated into switch l9.
The control panel 79 awaits actuation of switch l9 by the user at which time the drive motor is re-actuated and rotates the carousel assembly to complete the 3600 cycle. As the container 53 passes over the discharge opening 46, the heated food falls through the opening 46 and into funnel 34 and through discharge chute 40 and out opening 16 in the front panel. The carousel assembly 36 continues to rotate until the magnetic reed switch 75 is actuated by magnet 65. The vending machine is then ready for another cycle.
The control panel 79 can be programmed to detect ` malfunction conditions caused by a jammed motor 42 or the magnetic reed switches 73 and 75 not actuating within a predetermined time, or overheating caused by failure of the blower 69 or heater coil assembly 68. If any failures are indicated, one of the lights 18d indicating "Out of Order" is turned on and the motor 42 and heat gun 66 are turned off until the malfunction is corrected by a service ' repairmanO
The-modular dispensing mechanism allows for easy : 25 servicing of the mechanism and easy changes of the food supply. A serviceman can open access panel 79 which exposes an auto/manual switch 9l and operating button 93.
If the food supply needs to -be changed, either by a restocking of fresh supply or restocking of different .. . . : . . . - , . , ........ , :
,. . . . .
`` 2~9~6 foods, the switch 91 is moved to the manual position and button 93 is pressed. The carousel assembly 36 rotates as long as button 93 is pushed. The serviceman keeps button 93 pushed until the carousel assembly 36 is rotated to the loading position so the container 53 is aligned under the aperture 44. The serviceman can then open the trap door 70 at which time the food from the hopper can pass through the container 53 down to a secondary discharge chute 72 that ! leads to the access panel 76. When the manual auto switch 91 is in the auto position the operating push button 93 may be used to start the cooking cycle without having to insert coins for testing the operation of the vending machine.
The modular aspect of the dispensing unit 38 allows for easy maintenance and cleaning. Once the hopper 24 is unloaded, the hopper chute 26 and top plate 28 can he easily removed after wing nuts 31 at the top of bolts 30 are loosened and removed. The carousel assembly 36 can ~ then be lifted off of the drive shaft 48. The hopper chute !1 26, top plate 28 and the basket assembly 36 can be easily removed from the vending machine 10 and washed. The bottom plate 32 can be easily wiped clean as can the discharge funnel 34.
The carousel assembly 36, top plate 28, and hopper chute 26 can then be easily remounted. The hopper 24 be easily reloaded. The ease of changing the food I supply and cleaning the dispenser unit 38 promotes the regular maintenance and upkeep of the vending machine l0 and promotes the maintenance of fresh food in a clean and healthy atmosphere.

46 are the same radial distance from shaft 48 and circumferentially spaced 1800 apart.
As shown in Figure 3, 6 and 8, the bottom plate 32 has a trap door 70 which is aligned directly under ~-. 5 aperture 44 and when open communicates with a secondary :, ,- discharge chute 72 which extends to the back panel 74 which .
.~ has an access door 76. The bacX panel 74 can also be provided with air vents 77.
.The carousel assembly 36 includes two spaced ,~I 10 apart mesh screens 50 which act as two opposing side walls .,j,,.
;and two other opposing solid side walls 52. The screens so and walls 52 define a container 53. The container 53 has ~:an open bottom 54 and an open top 56. The open top 56 is ~,aligned with an opening 58 in a closing plate 60 which is ,, ~:
mounted adjacent to and under the top plate 28. The one edge of the opening 58 in closing plate 60 has a canted '~flange 59.
The solid side walls 52 extend substantially the whole length of the top and bottom plate beyond the mesh '20 screens 50. The bottom edges of the side walls 52 are mounted onto a drive plate 64 which radially extends from drive shaft 48. The drive shaft 48 turns the drive plate 64 which in turn rotates the carousel assembly 36 about the drive shaft 48. The drive plate 64 has a magnet 65 mounted ~t25 thereon. The underside of the bottom plate 32 has two ~:;imagnetic reed switches 73 and 75 which interact with magnet i;:,l .
I~ 65.
~!
A heating gun 66 has a heating coil assembly 68 ~,~in the form of a nozzle pointed to the space 29 between the ~.' , ' :

A control panel 79 is operably connected to the reed switches 73,75, coin mechanism 20, lights 18, switches 19, heater gun 66, blower 69 and drive motor 42 via electrical wire 78, 80, 82, 84, 86 and so. The control panel 79 may be of any well known mechanical, electromechanical or electronic mechanism such as a printed circuit board and can be programmed in known manner to control and operate dispenser unit 38 in a programmed sequence.
In operation, the hopper 24 is filled with the food to be dispensed such ~s cashews, peanuts, or sunflower seeds. For this purpose the top section 22 can be opened ; to allow food supplies to be loaded into the hopper 24.
In the stand-by position the container 53 is opposite the heat gun 66 and between the supply chute aperture 44 and discharge opening 46. Upon the input of the appropriate coinage in the mechanism 20, the control panel 79 actuates the drive motor 42 which rotates the motor 42 which starts to rotate the basket assembly 36.
The carousel assembly rotates about drive shaft 48. When the opening S8 rotates under the aperture 44, a portion of , food in hopper 24 falls into the container 53 and rests on 7 bottom plate 32. As the carousel assembly 36 continues to rotate about shaft 48, the flange 59 pushes up any food ; supply out of the way as the opening 58 in the closing . . . .
WO91/15144 PCT/US9~/02273 ~ 2 ~ 6 plate 60 becomes misaligned with the aperture 44 to prevent wedging of food between the two plates 28 and 60.
Simultaneously as the carousel 36 starts to rotate the control panel also powers up the heater gun 66 and turns on one of the lights 18a which has an appropriate legend to instruct the operat~r to get a cup or bag. The carousel assembly 36 continues to rotate sliding the food on plate 32 until the magnetic reed 73 switch 75 is actuated by the magnet 65 on the drive plate 64 at which time the control panel deactuates the motor 42.
Alternatively, a predetermined delay can be introduced before the motor stops.
The carousel assembly and bottom plate 32 and top plate 28 create a tubular channel through which the heated air from the heat gun 66 as shown in Figure 7 can be channeled through the transverse mesh screens 50 to heat , the food that fell into the container 53. The air flow ~: through the channel, deflects upward on Section 33 and passes out through vents 77.
~, 20 The heating continues for a period of time , determined by the control panel. The time the heat gun 66 is actuated is variable. The control panel 79 can take into account the internal temperature within the carousel assembly before the coins actuated the vending machine cycle. During this heating sequence the controller actuates one of the lights 18b which has an appropriate legend such as "Place Cup Under Chute." At the end of the i' predetermined heating time the heater coil assembly 68 is , turned off. The blower 69 of the heat gun 66 can continue ;
~ :, ' ' " ' ' "" , ' , : ' ~ ' ' ' WOs~/151~ PCT/US91/02273 2~17~8~ lo ~
for a few seconds to cool the coil assembly 68 and then it also is turned off. One of the lights 18c flashes ~o properly instruct the operator to ~Press When Ready.
Light 18c is incorporated into switch l9.
The control panel 79 awaits actuation of switch l9 by the user at which time the drive motor is re-actuated and rotates the carousel assembly to complete the 3600 cycle. As the container 53 passes over the discharge opening 46, the heated food falls through the opening 46 and into funnel 34 and through discharge chute 40 and out opening 16 in the front panel. The carousel assembly 36 continues to rotate until the magnetic reed switch 75 is actuated by magnet 65. The vending machine is then ready for another cycle.
The control panel 79 can be programmed to detect ` malfunction conditions caused by a jammed motor 42 or the magnetic reed switches 73 and 75 not actuating within a predetermined time, or overheating caused by failure of the blower 69 or heater coil assembly 68. If any failures are indicated, one of the lights 18d indicating "Out of Order" is turned on and the motor 42 and heat gun 66 are turned off until the malfunction is corrected by a service ' repairmanO
The-modular dispensing mechanism allows for easy : 25 servicing of the mechanism and easy changes of the food supply. A serviceman can open access panel 79 which exposes an auto/manual switch 9l and operating button 93.
If the food supply needs to -be changed, either by a restocking of fresh supply or restocking of different .. . . : . . . - , . , ........ , :
,. . . . .
`` 2~9~6 foods, the switch 91 is moved to the manual position and button 93 is pressed. The carousel assembly 36 rotates as long as button 93 is pushed. The serviceman keeps button 93 pushed until the carousel assembly 36 is rotated to the loading position so the container 53 is aligned under the aperture 44. The serviceman can then open the trap door 70 at which time the food from the hopper can pass through the container 53 down to a secondary discharge chute 72 that ! leads to the access panel 76. When the manual auto switch 91 is in the auto position the operating push button 93 may be used to start the cooking cycle without having to insert coins for testing the operation of the vending machine.
The modular aspect of the dispensing unit 38 allows for easy maintenance and cleaning. Once the hopper 24 is unloaded, the hopper chute 26 and top plate 28 can he easily removed after wing nuts 31 at the top of bolts 30 are loosened and removed. The carousel assembly 36 can ~ then be lifted off of the drive shaft 48. The hopper chute !1 26, top plate 28 and the basket assembly 36 can be easily removed from the vending machine 10 and washed. The bottom plate 32 can be easily wiped clean as can the discharge funnel 34.
The carousel assembly 36, top plate 28, and hopper chute 26 can then be easily remounted. The hopper 24 be easily reloaded. The ease of changing the food I supply and cleaning the dispenser unit 38 promotes the regular maintenance and upkeep of the vending machine l0 and promotes the maintenance of fresh food in a clean and healthy atmosphere.
