Abstract
Abstract SEED CUP ASSEMBLY Abstract of the Disclosure The metering cup assembly is disclosed for use in combination with a pneumatic seeding or fertilizing device. The assembly includes a casing which is secured to the under-side of a hopper carrying seed, fertilizing or other granular material and the assembly is connected into a conduit in the pneumatic system. A metering component is journalled for rotation in the casing and provides a metering passageway for seed or other granular material therefrom the hopper into the pneumatic passageway. The metering device is adjustable to control the quantity of the material being transferred from the hopper into the conduit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
A seed cup assembly for use with a pneumatic seeding system and adapted for attachment to the underside of a pressurized hopper, comprising in combination a discharge casing; a conduit secured to and in communication with the lower end of said casing and adapted for insertion into the pneumatic system; a rotatable shaft extending transversely through said casing; a metering component journalled for rotation on said shaft and communicating with said casing and providing passage for seed or the like between said hopper and said conduit; said metering component being adjustably positioned within said casing for controlling the quantity of granular material transferred from the hopper to the conduit; said metering component comprising a cylindrical body having a plurality of elongated flutes thereon, said flutes engaging material within the hopper and depositing said material into the conduit as the metering component rotates within the casing; means sealing the fluted cylinder of the assembly with an adjacent wall of the casing; and means for moving the fluted metering component along said shaft to increase the exposure of the fluted surface to the inside of the casing.
Claim 2
Dependent Claim
185 words
A seed cup assembly for use with a pneumatic seeding system and adapted for attachment to the underside of a pressurized hopper, comprising in combination a discharge casing; a conduit secured to and in communication with the lower end of said casing and adapted for insertion into the pneumatic system; a rotatable shaft extending transversely through said casing; a metering component journalled for rotation on said shaft and communicating with said casing and providing passage for seed or the like between said hopper and said conduit; said metering component being adjustably positioned within said casing for controlling the quantity of granular material transferred from the hopper to the conduit; said metering component comprising a cylindrical body having a plurality of elongated flutes thereon, said flutes engaging material within the hopper and depositing said material into the conduit as the metering component rotates within the casing; means sealing the fluted cylinder of the assembly with an adjacent wall of the casing; and means for moving the fluted metering component along said shaft to increase the exposure of the fluted surface to the inside of the casing.
Claim 3
Dependent Claim
143 words
A seed cup assembly according to claim 1 wherein the metering component includes an elongated portion of reduced diameter extending concentrically outwards from the cylindrical fluted body; and a cylindrical slider freely and coaxially mounted on said elongated portion adjacent to said fluted cylinder and providing sealing means with the adjacent wall of the casing; the means sealing the fluted cylinder comprising a cylindrical housing, of greater diameter than said fluted cylinder, one end wall of said housing being secured to said rotatable shaft whereby the cylindrical housing is coaxially positioned over the portion of the fluted cylinder extending through the casing wall; and a disc shaped member at the other end of said cylindrical housing and having a peripheral outer surface providing the seal against the casing wall, and on inner surface profiled to match the fluted surface of the metering cylinder.
