IPC: G01G13/00
Filed: 1936-05-13
Abstract: 475,117. Delivering material from hoppers. LENHART, H. S. May 13, 1936, No. 13592. Convention date, May 14, 1935. [Class 78 (i)] [Also in Group XVIII] In an apparatus for automatically weighing out batches of material from a storage bin, the material is transferred from the bin to a weigh hopper by a mechanical feeder including a fluted feed roll 10 containing bouncing balls 14 for dislodging adhering material. A double or drum-like feed valve 16, 17 is provided above and below the feed roll to prevent running through after the drive of the feed roll is discontinued. When a power switch is closed, the feed valve 16, 17 is opened by a motor and the feed roll 10 is set in rotation by a further motor, the reverse operations taking place when the requisite weight, has been supplied. Should foreign matter stop the feed roll, a thermal overload relay overheats and rearranges the circuits so as to reverse the direction of rotation of the feed roll. The reversal causes the clogging material, unless of unusual size, to drop into of the flutes of the feed roll and thence into the weigh hopper, the new direction of rotation being maintained until clogging again occurs. Specification 392,010, [Group XVIII], is referred to.
