Abstract
Abstract A popcorn popper wherein the corn is popped in a dry condition in a drum rotating on a horizontal axis. An electrical heater is attached to the periphery of the drum. The drum has inner and outer cylinder walls with a popping chamber between the walls and discharge chamber within the inner wall. A separator gate guides corn after it is popped from the popping chamber into the discharge chamber. A discharge chute extends outwardly from the discharge chamber and a carrier blade within the inner wall moves the popped corn to a position to be dumped into the discharge chute. There is also a fan for blowing the popped corn from the discharge chute upwardly through a spout into a container and the fan and drum are driven by the same motor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
In a popcorn popper, (a) an outer housing, (b) a roasting drum mounted in the housing for rotation on its horizontal center axis, (c) drive means for rotating the drum, (d) said drum having a popping chamber and a discharge chamber, (e) heating means for heating the popping chamber, (f) means for depositing corn kernels in the popping chamber for popping therein as the drum is rotated, (g) separator means between the popping chamber and discharge chamber for directing corn kernels after they are popped into the discharge chamber, and (h) means for discharging popped corn from the discharge chamber and out of the roasting drum while the drum continues to rotate.
Claim 2
Dependent Claim
112 words
In a popcorn popper, (a) an outer housing, (b) a roasting drum mounted in the housing for rotation on its horizontal center axis, (c) drive means for rotating the drum, (d) said drum having a popping chamber and a discharge chamber, (e) heating means for heating the popping chamber, (f) means for depositing corn kernels in the popping chamber for popping therein as the drum is rotated, (g) separator means between the popping chamber and discharge chamber for directing corn kernels after they are popped into the discharge chamber, and (h) means for discharging popped corn from the discharge chamber and out of the roasting drum while the drum continues to rotate.
Claim 3
Dependent Claim
14 words
The subject matter of claim 1 wherein the popping chamber encircles the discharge chamber.
Claim 4
Dependent Claim
62 words
The subject matter of claim 2 wherein the separator means comprises a director member disposed within the popping chamber for directing popped corn into the discharge chamber during rotation of the drum, said director member defining an opening in the popping chamber of such a size as to permit unpopped kernels to bypass the member and be retained in the popping chamber.
Claim 5
Dependent Claim
134 words
In a popcorn popper, (a) an outer housing, (b) a roasting drum mounted in the housing for rotation on its horizontal center axis, (c) drive means for rotating the drum, (d) heating means for transmitting heat to the drum, (e) said drum having inner and outer concentrically positioned cylindrical walls providing an inner discharge chamber within the inner wall and a popping chamber between the walls, (f) means for depositing corn kernels in the popping chamber for popping therein as the drum is rotated. (g) separator means between the inner and outer cylinders for causing corn popped in the popping chamber to move into the discharge chamber, (h) a discharge chute having open communication with the discharge chamber, and (i) means on the inner cylinder for directing popped corn therein into the discharge chute.
Claim 6
Dependent Claim
134 words
In a popcorn popper, (a) an outer housing, (b) a roasting drum mounted in the housing for rotation on its horizontal center axis, (c) drive means for rotating the drum, (d) heating means for transmitting heat to the drum, (e) said drum having inner and outer concentrically positioned cylindrical walls providing an inner discharge chamber within the inner wall and a popping chamber between the walls, (f) means for depositing corn kernels in the popping chamber for popping therein as the drum is rotated. (g) separator means between the inner and outer cylinders for causing corn popped in the popping chamber to move into the discharge chamber, (h) a discharge chute having open communication with the discharge chamber, and (i) means on the inner cylinder for directing popped corn therein into the discharge chute.
Claim 7
Dependent Claim
44 words
The subject matter of claim 4 wherein the separator means comprises a gate extending outwardly from the inner wall toward the outer wall and angling forwardly relative to the direction of rotation to guide kernels popped in the popping chamber into the discharge chamber.
Claim 8
Dependent Claim
49 words
The subject matter of claim 4 wherein the chute opens upwardly within the discharge chamber and the said inner wall has a carrier blade directed inwardly therefrom in a generally radial direction to carry popped corn in the discharge chamber upwardly during rotation and dump it into the chute.
Claim 9
Dependent Claim
126 words
In a popcorn popper having a base frame, (a) a rotary drum in which corn is popped mounted on the frame, (b) motor means on the frame having driving connection with the drum for rotating the same while corn is popped therein, (c) a discharge chute on the frame angling downwardly and outwardly from the drum, (d) means in the drum for discharging popped corn from the drum into the chute, (e) a discharge spout extending upwardly from the extended end of the chute, (f) a fan driven by the motor means, and (g) conduit means connecting the fan with the extended end of the chute to conduct an air blast from the fan to blow popped corn discharging through the chute upwardly through the spout.
