Publication number: 20070163859Abstract: An auger airlock assembly and end dump housing having a spring loaded bottom for use in a bulk loader which utilizes a source of negative pressure to create a suction air stream that draws particulate materials into the loader for transfer, via the auger assembly, to a location remote of the loader. Materials exiting the auger assembly accumulate within the housing to a point wherein, once the accumulated material has acquired a certain weight, the bottom of the housing is forced open to permit discharge of the material, and, once the material is removed, and is not present in enough quantity to maintain the bottom of the housing to remain open, the spring loaded connection biases the bottom back into a position sealably closing the housing. The bottom of the housing may also be opened by the auger feeding more material into an already full housing, whereby the material is compressed so as to force the door open.Type: ApplicationFiled: April 6, 2006Publication date: July 19, 2007Inventors: Max Noble, Frank Rempel

Patent number: 6068108Abstract: A screw conveyer for conveying metal turnings from a machining operation. The chip screw conveyor includes an auger-like screw configured to move metal turnings in a given direction. The conveyor includes a tubular housing and an input chute defining an input opening. A secondary feeder arm is pivoted to the conveyor housing. The arm is pivoted out of the way in direction when agglomerated scraps/chips are dumped threw input opening into the input chute.

The screw chamber houses a feed screw which enters a feeder section in a transition region at the front wall of the agitator chamber. An agitator draws material away from the transition region of the agitator chamber.Type: GrantFiled: May 7, 1993Date of Patent: August 2, 1994Assignee: Hyer Industries, Inc.Inventor: Robert L. Andrews

Patent number: 5219103Abstract: An apparatus for the storage and dispensing of particulate coffee in a domestic refrigerator comprising a sealed bin for preserving the freshness of the particulate coffee and a manually operated transfer mechanism for dispensing the coffee into a container for the preparation of coffee beverages. The transfer mechanism includes a rotary auger and a pick-up wheel disposed within the bin and operatively connected to a manual crank on the front of the bin. The auger feeds the coffee to the pick-up wheel, which deposits the coffee into a graduated chute from which the user may dispense the coffee to a suitable container.Type: GrantFiled: December 30, 1991Date of Patent: June 15, 1993Assignee: Whirlpool CorporationInventor: Dwight A. Carper

Patent number: 5160016Abstract: A feed hopper assembly for feeding granular material to a feed screw in the bottom of the hopper, the assembly including a frame for supporting a flexible type feed hopper, one or more roller assemblies mounted on the frame in a position to engage the sides of the feed hopper, each roller assembly including a shaft and a tube mounted for rotary motion on the shaft, the shaft being eccentrically mounted on the frame to move the tube into and out of engagement with the hopper.Type: GrantFiled: January 16, 1992Date of Patent: November 3, 1992Assignee: AccuRate, Inc.Inventor: Stephen L. Moksnes

Patent number: 5156346Abstract: In general, paper shredders cut paper into narrow strips, and for such purpose, include narrow, somewhat delicate blades. A paper spreader for receiving shredded paper from a shredder, and compacting and cutting the paper into smaller pieces before distributing the paper pieces to a pile includes an outlet chute for receiving shredded paper from a shredder, an auger inclined upwardly and outwardly from the chute for compacting and conveying shredded paper away from the shredder, a deflector plate at the outer top end of the auger for deflecting paper carried by the auger, and a blade on the deflector plate extending tangentially of the auger shaft for cooperating with a sharpened, upwardly tapering auger flight to shear the paper carried by the auger.Type: GrantFiled: September 12, 1991Date of Patent: October 20, 1992Inventor: W. Lyle Portz

Patent number: 5154326Abstract: A conveying device used in weighing apparatus for conveying powder comprising a conveying cylinder which is subjected to a vibrational movement by a vibrator to finely control the powder exited from the cylinder. Inside the conveying cylinder, there is a shaft with first and second blade segments which is actuable to rotate, thereby receiving powder from a loading hopper and exiting the powder to an outside. The vibrational movement of the conveying cylinder is irrespective of the rotational movement of the shaft, and either one or both of the conveying cylinder and the shaft is selected to operate to obtain a desired quantity of powder, ranging from a very small quantity where only the vibrator operates to a very large quantity where both the vibrator and the shaft operate.Type: GrantFiled: March 7, 1991Date of Patent: October 13, 1992Assignee: Gain Lab CorporationInventors: Yuen-Wai Chang, Chiou-Fwu Chen

Patent number: 5143202Abstract: A screw conveyor with a slowly rotating feed screw for precision metering by conveying very small amounts of loose material between screw threads, the same amount of loose material being discharged from the end of the conveyor with each turn of the screw. During the relatively short time interval of a single revolution, which can last one minute or even a multiple thereof as needed, the conveyor capacity itself fluctuates, since discrete amounts of the material being conveyed are always delimited by the individual threads of the feed screw. In order for a screw conveyor to be usable for precision metering of very small amounts to be conveyed; i.e. for conveying very small amounts with a high degree of constancy without the periodicity caused by the nature of the feed screw, the screw conveyor is provided with a rotatably mounted tube surrounding the discharge end of the fixed feed tube and which is driven at a rotational speed proportional to the rotational speed of screw.Type: GrantFiled: September 12, 1991Date of Patent: September 1, 1992Assignee: K-Tron Technologies, Inc.Inventors: Rolf Lehmann, Reinhold Hodel

Patent number: 5125242Abstract: An ice dispensing and crushing apparatus is disclosed for dispensing and selectively crushing pieces of ice. The apparatus includes a supply bin for containing and supplying pieces of ice, a conveying trough formed at least partially within a lower portion of the supply bin and extending in an inclined manner toward a dispensing housing through which ice pieces can be dispensed. A helical conveyor is mounted for rotation in the conveying trough and is operable to convey individual pieces of ice one-by-one toward a dispensing opening formed in a lateral side of the dispensing housing. An ejection device, such as an ejection bar, is mounted adjacent the helical conveyor and acts to eject extra pieces of ice so as to assure the individual successive conveyance of the ice pieces.Type: GrantFiled: April 26, 1991Date of Patent: June 30, 1992Assignee: Gaggenau-Werke Haus- und Lufttechnik GmbHInventor: Georg von Blanquet
