Patent ID: 8061568

Claim:
A fiber blowing and filling machine comprising: a. a hopper for receiving fiber, wherein the hopper houses a first shaft longitudinally disposed in the hopper and a blade assembly comprising a first X-shaped members and a second X-shaped member disposed at each end of the first shaft and at least four blades running diagonally to the first shaft and connected to the first and second X-shaped members, wherein the four blades connect the first, second, third, and fourth free ends of the first X-shaped member to the second, third, fourth and first free ends of the second X-shaped member, respectively, for fluffing and dispersing the fiber as the first shaft is rotated; b. a dispensing assembly located below the hopper, comprising: i. a housing open on top; ii. a first aperture on a first surface of the housing; iii. a second aperture on a second surface of the housing opposite the first surface, the second aperture being in line with the first aperture; iv. a second shaft longitudinally disposed between the first and second surfaces of the housing and above the first and second apertures; v. a paddle assembly comprising a hollow central portion and a plurality of vanes with flexible edges projecting from the central portion in a radial orientation, the paddle assembly mounted over the second shaft by securely receiving the second shaft within the hollow central portion creating a pocket when the first and second apertures are between a pair of the vanes, the edges of which contact the surfaces of the housing such that the pocket created is substantially isolated from the hopper and rest of the dispensing assembly; c. a drive assembly for rotating the first and second shafts; d. a blower; e. an air inlet hose connecting the blower output and the first aperture in the housing; and f. an exit hose connected to the second aperture wherein, when the blower and the drive assembly are activated, the fiber in the hopper is dispersed and gets collected between a pair of the vanes, which rotate further creating the pocket filled with the fiber to be blown into the exit hose by the air from the blower output, wherein the paddle assembly comprises a plurality of blades projecting from the central hollow portion in a radial orientation, an equal number of substantially V-shaped plates, and an equal number of flexible sheets whose length from one end of the sheet to the other end of the sheet is longer than the length of any of the V-shaped plates from one end of the plate to the other end of the plate, the flexible sheets, in major part, secured between the V-shaped plates and a pair of the subsequent blades, thereby forming the vanes.
