Patent number: 10766694Abstract: An alternative bottom drop and straight tee discharge from bulk tank conveying granular material, the tee having extensions for the automatic and manual operations of a disc valve, pivotally located within the horizontal section of the tee, during functioning. The disc valve may be manually operated, or pivoted through motorized operations, to allow for the alternative flow of bulk material from the vehicle hopper. The disc valve has an annular disc, integrally formed with upright supports, that are bearing mounted by shafts to the sidewalls of the structured tee.Type: GrantFiled: January 28, 2019Date of Patent: September 8, 2020Assignee: Bulk Tank, Inc.Inventors: David E Sisk, Jason Huskey, Peter Kemp

Patent number: 10753526Abstract: An unload elbow with spherical wear pocket is disclosed which comprises a body having an inlet end, an outlet end, and a spherical wear pocket formed near the outlet end. The spherical wear pocket is capable of trapping material that is being unloaded through the unload elbow to trap a portion of material being unloaded so that any other material being unloaded will contact the trapped material and not impact the wear pocket to prematurely wear out the unload elbow.Type: GrantFiled: March 9, 2015Date of Patent: August 25, 2020Assignee: Bulk Tank Inc.Inventor: David E.

Patent number: 10145500Abstract: A hopper tee having a horizontal portion through which granular material is unloaded from a tank trailer or hopper car, the hopper tee integrally forms a vertical segment, that secures with the bottom of the hopper, to provide for unloading of granular material for usage or storage. The upper front portion of the tee, as it transitions from its vertical segment to the horizontal flow path has secured or cast therewith a ledge, that provides for accumulation of the unloading granular material therein, to function as a wear pad to resist against abrasion and accelerated wear out of the tee, at that location, during prolonged usage.Type: GrantFiled: April 6, 2017Date of Patent: December 4, 2018Assignee: Bulk Tank, IncInventor: David E Sisk

Patent number: 10040626Abstract: A directional hopper tee has a fluted interior vertical pipe that merges into a horizontal pipe. The horizontal pipe has an inlet that may receive bulk material, and subject to pressurized air that conveys the bulk material through the hopper tee. Bulk material may be discharged from a hopper through the vertical pipe, for conveyance for discharge from the horizontal pipe of the tee. A closure gate or door is provided through the bottom of the tee, generally in alignment with the vertical pipe, to allow for discharge or dropping of the granular material directly downwardly through and from the tee. The arcuate door is hinged on one side, and is locked by a cam lock on the opposite side, when located into closure against the bottom of the tee, but can be forced opened, through its cam mechanism, to provide for opening of the arcuate door and allow a direct downward discharge of the granular bulk material, from any hopper, and through the drop opening of the tee, as required.Type: GrantFiled: July 22, 2015Date of Patent: August 7, 2018Assignee: Bulk Tank, Inc.Inventor: David E Sisk

Patent number: 9057445Abstract: An improved disc for a butterfly valve having reduced structure within the bore of the valve, so as to minimize obstruction to the flow of granular material therethrough. Accelerated flow of granular material through the valve is obtained because of the thin dimensions of the butterfly valve. The modified disc includes upper and lower sockets, most of its structure is outside the perimeter of the disc. The disc may be of arcuate shape.Type: GrantFiled: February 19, 2013Date of Patent: June 16, 2015Assignee: Bulk Tank, Inc.Inventor: David E. Sisk

Patent number: 8419072Abstract: An elbow has an elongated inlet, an elongated outlet tube that merges with the inlet at a shallow angle, and an endwall opposite the inlet. The round inlet receives product and leads to a first chamber with a rounded bottom. Opposite the bottom, the inlet has a pitch at the transition to the outlet tube. The outlet tube continues upwardly from the pitch to an exit. Within the outlet, a third chamber extends from the first chamber. The first chamber and the third chamber intersect at the second chamber that provides a transition to the flow of product from the first chamber to the angle of the third chamber. Within the second chamber, conveyed product forms a shallow eddy so that additional product flows over the eddy enroute to the outlet.Type: GrantFiled: August 2, 2011Date of Patent: April 16, 2013Assignee: Bulk Tank, Inc.Inventor: David E.
