Patent number: 10174769Abstract: The present invention is a pump used for applications where a solid is present in wastewater and other liquids that requires cutting and reduction in size so as to pass the solid through the inlet to the outlet of the pump. The pump has a pump casing with an inlet and an outlet formed therein. A drive unit rotates a drive shaft extending axially through the pump casing to an impeller and a cutter bar. The pump is further configured with a radial cutter ring assembly positioned adjacent the cutter bar and the inlet providing a shredding cutting action of solids between the rotating cutter bar sliding past a radial cutter ring assembly held stationary, e.g. cutting blades formed in an edge of the cutter bar rotate across an internal surface of the radial cutter ring assembly.Type: GrantFiled: June 28, 2017Date of Patent: January 8, 2019Assignee: BJM Pumps, LLCInventor: Brian M. Mitsch

Publication number: 20150377255Abstract: The present invention is a pump (100) used for applications where a solid (130) is present in wastewater and other liquids that requires cutting and reduction in size so as to pass the solid (130) through the inlet (105) to the outlet (106) of the pump (100). The pump (100) has a pump casing (104) with an inlet (105) and an outlet (106) formed therein. A drive unit (170) rotates a drive shaft (113) extending axially through the pump casing (104) to an impeller (109) and a cutter bar (102). The pump (100) is further configured with a radial cutter ring assembly (101) positioned adjacent the cutter bar (102) and the inlet (105) providing a shredding cutting action (140) of solids (145) between the rotating cutter bar (102) sliding past a radial cutter ring assembly (101) held stationary, e.g. cutting blades (160) formed in an edge (118) of the cutter bar (102) rotate across an internal surface (121) of the radial cutter ring assembly (101).Type: ApplicationFiled: July 31, 2014Publication date: December 31, 2015Applicant: Bjm Pumps LLCInventor: Brian M.

Patent number: 5336850Abstract: The invention of this disclosure is an economical sealing device that utilizes two seals to protect an electrical power cord or cable from its environment. The cord or cable couples a power source to electrical equipment that is located behind a material. A standard cord grip is used to push a molded assembly, (which is located at the end of the cable passing through the material) against a molded seat assembly to obtain a first seal. The second seal is obtained by tightening the cord grip with a nut.Type: GrantFiled: October 19, 1992Date of Patent: August 9, 1994Assignee: General Signal CorporationInventor: Brian M. Mitsch

Patent number: 5213469Abstract: A pump which includes a housing and a shaft disposed within the housing having an axis. The apparatus also includes apparatus for mounting the shaft within the housing for rotational movement thereof and an impeller having a geometric center carried on the shaft. A fluid inlet in the housing is disposed with a first opening disposed in eccentric relationship to the geometric center of the impeller. In some forms of the invention the opening is generally shaped like a dog bone with the two largest parts thereof spaced apart from the geometric center of the impeller.Type: GrantFiled: January 10, 1992Date of Patent: May 25, 1993Assignee: General Signal CorporationInventors: Brian M. Mitsch, Ralph D. Austen, Robert S. Jones

Patent number: 5044566Abstract: A grinder pump which includes a housing; a shaft disposed within the housing having an axis; apparatus for mounting the shaft within the housing for rotational movement thereof; a moveable cutter carried on the shaft, apparatus for coupling the moveable cutter to the shaft to cause rotation of the moveable cutter upon rotation of the shaft. A stationary cutter is carried by the housing and the moveable cutter cooperates with the stationary cutter to perform cutting along respective surfaces of the moveable cutter and the stationary cutter. The respective surfaces of the stationary and moveable cutters are substantially within a plane that is substantially perpendicular to the axis; and apparatus resiliently biases the moveable cutter against the stationary cutter.Type: GrantFiled: December 27, 1989Date of Patent: September 3, 1991Assignee: General Signal CorporationInventor: Brian M.
