Vibrating Hopper Patents (Class 111/75)
  • Patent number: 5662053
    Abstract: Many people like to plant a garden. The earth is prepared for receiving the seeds. A person can dispense the seeds into the earth. An even distribution of the seeds is difficult. The subject invention comprises a guide for holding seeds. One end of the guide is an open funnel for directing the flow of the seeds to the earth. The guide is attached to an electro-mechanical device which vibrates. The vibration causes the seeds to flow through the open funnel. A person utilizing the guide and the electro-mechanical device can control the rate of flow of seeds to the earth. The result is a more even distribution of the seeds in the garden than previously realized by dispensing the seeds by hand. The electro-mechanical device can be an electric screw driver having a housing, an electric motor and batteries. There are many different electric screw drivers commercially available.

  • Patent number: 4155315
    Abstract: A mobile spreader of the type drawn by a tractor includes a hopper mounted on a roller. The roller is provided with a jarring strip which imparts a jolt to the hopper on each revolution of the roller. This jolting action prevents bridging of the material in the hopper, knocking the hung-up material down into the lower portion of the hopper where an agitator and an impellor further stir up the material. The cooperative effect of the jarring strip, the agitator and the impellor is to provide a steady supply of material, even when moist material is being distributed. The rate of application of the material is controlled by a slidable apertured plate disposed across an opening in the bottom of the hopper. The spreader may be selectively provided with a rake, a floater plate, and a spiker. The spiker may be attached in front of the roller to open the turf to receive the material, or behind the roller to work the applied material into the turf. In addition, the spiker aerates the turf.
