Claim 3

The improvement according to claim 1 wherein said container is tubular shaped having an open top positioned beneath an opening in the bottom of said trough.

Claim 4

The improvement according to claim 1 wherein said pan includes a raised cone-shaped central bottom portion, said cone-shaped gate having an opened bottom, said container being opened by lowering said cone into the proximity of said central portion of said bottom whereby the feed is dispensed out of said container and deflected along the walls of said cone-shaped gate and further along the walls of said central portions of said pan bottom.

Claim 5

The improvement according to claim 3 wherein said assembly includes a plurality of feed pans and associated containers suspended beneath said trough spaced apart from each other, each of said cone-shaped gate means being interconnected by said actuator means for raising and lowering of each of said gate means simultaneously such that measured amounts of feed are simultaneously deposited in each of said pans when said gate means are lowered.

Claim 6

The improvement according to claim 4 wherein said actuator means comprises a rod-like means extending the length of said trough and a plurality of individual cables, one each for each pan assembly, said cables being attached at one end to said rod-like means and at the other end to said gate means whereby transverse movement of said rod-like means provides simultaneous raising or lowering of said gate means.

Claim 7

The improvement according to claim 5 wherein adjustment means are provided for each of said cables to position and tension said cables and associate gate means relative said rod-like means.

Claim 8

The improvement according to claim 1 wherein said assembly further includes a tubular shield surrounding at least the lower portion of said container and extending downwardly toward said pan the lower margin of said shield being spaced from said pan defining an annular opening, and adjustment means for suspending said shield at selective heights above said pan, whereby the depth of feed exposed in said pan to poultry is preselected by the height of the lower margin of said shield, said shield further shielding the interior of said pan assembly from the poultry.

Claim 9

A feeder pan assembly connected to a trough, said assembly including a feed-accumulating housing wherein a preselected quantity of feed may be accumulated and a feed-dispensing pan from which the poultry may take feed, said accumulating housing having a top portion with an opening communicating with an opening in the bottom of the trough and a bottom portion with an opening communciating with said dispensing pan to replenish feed therein; and gate means cooperative with said opening in said bottom and movable between a closed and open position whereby when said gate means is in said closed position, said housing is filled with feed from said trough and when said gate means is open, said volume of feed collected in said housing is dispensed by gravity into said pan said bottom opening in said housing being circular and said gate means being cone-shaped and having a base diameter greater than the diameter of said bottom opening whereby said housing is closed when said cone-shaped gate means is raised into abutting engagement with the bottom of said housing; and actuator means for moving said gate means between said open and closed position.

Claim 10

A feeder pan assembly connected to a trough, said assembly including a feed-accumulating housing wherein a preselected quantity of feed may be accumulated and a feed-dispensing pan from which the poultry may take feed, said accumulating housing having a top portion with an opening communicating with an opening in the bottom of the trough and a bottom portion with an opening communciating with said dispensing pan to replenish feed therein; and gate means cooperative with said opening in said bottom and movable between a closed and open position whereby when said gate means is in said closed position, said housing is filled with feed from said trough and when said gate means is open, said volume of feed collected in said housing is dispensed by gravity into said pan said bottom opening in said housing being circular and said gate means being cone-shaped and having a base diameter greater than the diameter of said bottom opening whereby said housing is closed when said cone-shaped gate means is raised into abutting engagement with the bottom of said housing; and actuator means for moving said gate means between said open and closed position.

Claim 11

The feeder pan assembly according to claim 8 wherein a plurality of feed-accumulating housing, feed dispensing pans and cone-shaped gate means are spaced from each other along said trough, each of said cone-shaped gate means being interconnected by said actuator means for raising and lowering of each of said gate means simultaneously between said open and closed positions such that measured amounts of feed are simultaneously deposited in each of said pans when said gate means are lowered.

Claim 12

The feeder pan assembly according to claim 9 wherein said actuator means comprises a rod-like means extending the length of said trough and a plurality of individual cables, one each for each pan assembly, said cables being attached at one end to said rod-like means and at the other end to said gate means whereby transverse movement of said rod-like means provides a simultaneous raising or lowering of said gate means.

Claim 13

The pan assembly according to claim 8 wherein said assembly further includes a tubular shield surrounding at least the lower portion of said housing and extending downwardly toward said pan, the lower margin of said shield being spaced from said pan defining an annular opening, and adjustment means for suspending such shield at selective heights above said pan, the depth of feed exposed in said pan to poultry being preselected by the height of the lower margin of said shield.

Claim 14

A feeder pan assembly comprising a cover member for suspension from a feed trough; a dish-shaped feed pan suspended from said cover member; a feed-accumulating container anchored to said cover member for communication with the trough and having a bottom opening; gate means disposed at the bottom of said container movable between an open and closed position, the bottom of said container being spaced above said pan such that when said gate means is closed, said feed-accumulating container is filled with feed and when said gate means is open, a preselected amount of feed is dispensed by gravity from said container into said pan, said gate means comprising a cone shape and having a base diameter greater than the diameter of said bottom opening; and actuator means for moving said gate means between said open and closed position.

Claim 15

A feeder pan assembly comprising a cover member for suspension from a feed trough; a dish-shaped feed pan suspended from said cover member; a feed-accumulating container anchored to said cover member for communication with the trough and having a bottom opening; gate means disposed at the bottom of said container movable between an open and closed position, the bottom of said container being spaced above said pan such that when said gate means is closed, said feed-accumulating container is filled with feed and when said gate means is open, a preselected amount of feed is dispensed by gravity from said container into said pan, said gate means comprising a cone shape and having a base diameter greater than the diameter of said bottom opening; and actuator means for moving said gate means between said open and closed position.

Claim 16

The feeder pan assembly according to claim 12 wherein said gate means and feed accumulating housing are shielded by a shield member encapsulating at least the lower portion of said container, said shield means being adjustably suspended from said cover member at varying heights above the bottom of said pan.
