  "abstract": "A material flow assist mechanism for a feed hopper using a vertically aligned rotating auger includes a frame, the frame having a pair of spaced apart first and second telescoping arms attached to frame, and a connector to link a shaft of a motor to the auger for auger and material flow assist mechanism rotation. Each of first and second telescoping arms have an elongated member mounted to a plate-containing end portion of each respective first and second telescoping arms. Rotation of the material flow assist mechanism by the motor rotates the first and second elongated members for material dispensing out a hopper. Dispensing of the material from the hopper results in extension of portions of the first and second telescoping arms such that the elongated members and plate travel with a top portion of the material as the top portion of the material in the hopper descends during dispensing.",
  "claims": [
    "1. A material feeder comprising: a hopper having a top opening and a bottom opening; a hopper cover configured to cover the top opening; an auger arranged vertically in the hopper; a material flow assist mechanism configured to be positioned in the hopper to assist in material flow to the auger; a motor for rotating the material flow assist mechanism and the auger, the material flow assist mechanism further comprising: a frame including a pair of spaced apart first and second telescoping arms attached to frame and a connector to link a shaft of the motor to the auger for auger and material flow assist mechanism rotation, the spacing of the first and second telescoping arms being asymmetric so that the first telescoping arms is closer to a longitudinal axis of the frame so as to position the first telescoping arm closer to the auger than the elongated member of the second telescoping arm; each of the first and second telescoping arms including an elongated member mounted to an end portion of each respective first and second telescoping arms; a plate attached to the end portions of the first and second telescoping arms above each of the elongated members; wherein the motor rotates the material flow assist mechanism and auger, the rotation of the material flow assist mechanism rotating the first and second elongated members and agitating material in the hopper under the plate for material dispensing out a bottom opening of the hopper and dispensing of the material from the hopper results in extension of portions of the first and second telescoping arms such that the elongated members and plate travel with a top portion of the material as the top portion of the material in the hopper descends during dispensing.",
    "2. A material flow assist mechanism for a feed hopper using a vertically aligned rotating auger comprising: a frame including a pair of spaced apart first and second telescoping arms attached to frame and a connector to link a shaft of a motor to the vertically aligned rotating auger for vertically aligned rotating auger and material flow assist mechanism rotation, the spacing of the first and second telescoping arms being asymmetric so that the first telescoping arms is closer to a longitudinal axis of the frame so as to position the first telescoping arm closer to the vertically aligned rotating auger than the elongated member of the second telescoping arm; each of the first and second telescoping arms including an elongated member mounted to an end portion of each respective first and second telescoping arms; a plate attached to the end portions of the first and second telescoping arms above each of the elongated members; wherein the motor rotates the material flow assist mechanism and vertically aligned rotating auger, the rotation of the material flow assist mechanism rotating the first and second elongated members and agitating material in the hopper under the plate for material dispensing out a bottom opening of the hopper and dispensing of the material from the hopper results in extension of portions of the first and second telescoping arms such that the elongated members and plate travel with a top portion of the material as the top portion of the material in the hopper descends during dispensing.",
    "3. The feeder of claim 1, wherein the motor is a high torque low RPM motor.",
    "4. The feeder of claim 1, wherein the elongated members have a generally flat surface or a concave surface.",
    "5. A method of dispensing a material comprising: providing the feeder of claim 1, filling the hopper with a material to be dispensed, actuating the motor to rotate the auger and the material flow assist mechanism for a period of time to dispense the material from the hopper.",
    "6. The method of claim 5, wherein the material is in a granular or powder form.",
    "7. The method of claim 6, wherein the material is animal feed."

  "description_excerpt": "This application claims priority from provisional application No. 62/889,736, filed on Aug. 21, 2019, which is incorporated by reference in its entirety herein.\n\nThe invention discloses a material feeder device that has a material flow assist mechanism that assists in directing material to an auger mechanism for feeding purposes.\n\nIn the prior art, the use of vibrating mechanism to dispense powder is known as is shown in U.S. Pat. No. 8,096,285 to Wisecarver. These kinds of powder dispensers rely on a mechanism to vibrate the hopper that dispenses the powder. However, when powder is damp or wet, the vibrating mechanism does not have sufficient vibration powder to move the wet or damp powder and dispensing cannot be accomplished. Another example of a feeder is shown in Pre-Grant Publication No. 2017/0006825 to Knight, which is incorporated in its entirety herein and referred to below as the Knight publication. As such, a need exists for an improved material feeder or dispenser, and particularly a powder material feeder, and the invention responds to this need.\n\nAn object of the invention is to improve the dispensing of a material using an auger or other similar feeding mechanism. In one embodiment, the material feeder device includes a hopper to hold the material to be dispensed. Vertically arranged in the hopper is an auger that is connected to a motor to rotate the auger in the hopper.",
