Definitions

  • ABSTRACT This invention provides improvedmeans for suspending and vibration isolating material flow promoting apparatus from a flowable material container.
  • the improved means provided by the present invention comprises a member including a central portion, which can be arranged to extend generally vertically between the apparatus and the container, and first and second hollow end portions, located at the opposite ends of the central portion, which can be respectively interconnected to the apparatus and the container.
  • Each of the hollow end portions contains a vibration isolator, and each of the isolators has a bore, which will be arranged generally horizontally when the central portion of the member is arranged generally vertically, forrespectively receiving fastener means for securing thefirst end portion of the member to the apparatus and the isolator bores have their central axes offset from one another by an angle.
  • flowable means have been provided for promoting flow of stored fowable materials within and from a storage container.
  • these flow promoting means are not integrally formed with the container and, instead, comprise separately manufactured apparatus which is subsequently connected with the container.
  • flow promoting means are suspended from the container adjacent a discharge opening that is usually provided in the bottom of the container.
  • the improved means provided by the present invention comprises a member including a central portion, which can be arranged to extend generally vertically between the apparatus and the container, and first and second hollow end portions, located at the opposite ends of the central portion, which can be respectively intercon nected to the apparatus and the container.
  • Each of the hollow end portions contains a vibration isolator, and each of the isolators has a bore, which will be arranged generally horizontally when the central portion of the member is arranged generally vertically, for respectively receiving fastener means for securing the first end portion of the member to the apparatus and the second end portion of the member to the container.
