Patent number: 11912545Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.Type: GrantFiled: June 26, 2020Date of Patent: February 27, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Matthew Post, Gareth Mueckl, Matthew N.

Patent number: 6168163Abstract: A shaft seal is interposed between a tank and a rotating shaft extending through the tank and having a non-rotatable stator fixed to the tank and a rotor fixed for rotation to the shaft. A multiple labyrinth structure is formed between the rotor and the stator for preventing the ingress of contaminants from the tank and the egress of lubricant from the shaft. A self-aligning arrangement is constructed and arranged to permit the stator to shift axially along the shaft and compensate for various forces inflicted on the shaft as the shaft rotates.Type: GrantFiled: November 18, 1998Date of Patent: January 2, 2001Assignee: Mixer Systems, Inc.Inventors: John L. Thorson, Robert L. Komassa

Patent number: 5393139Abstract: A mounting assembly for the primary mixing paddles in a pan-type mixer includes a single bolt paddle support arm mounting and adjustment device, and a two bolt paddle mounting feature, both of which are constructed and located to provide reliable adjustability and demountability and to protect the assemblies against the ingress of contaminants and abrasive wear from the materials being mixed. The single bolt clamping device also provides simple vertical adjustment of the paddle height in a manner which retains the adjustment mechanism enclosed against the entry of contaminants. The two bolt paddle mounting assembly encloses both threaded connections inside the body of the paddles, and includes a protective enclosing shroud and positions the exposed bolt heads at the back of the assembly out of the direct path of abrasive materials.Type: GrantFiled: July 26, 1994Date of Patent: February 28, 1995Assignee: Mixer Systems, Inc.Inventors: John L. Thorson, Norman E. Anderson

Patent number: 5038914Abstract: A sorting conveyor for rail tie plates or the like including an inclined frame having an upper end and a lower end, and an endless conveyor belt formed of a plurality of links pivotally joined to each other. The links are designed to have plate retaining pockets formed thereon and the belt is adapted to travel a contoured path on the frame between the lower end and the upper end. The belt has an upper working strand and a lower slack strand. A hopper provides a supply of randomly oriented tie plates to the lower end of the conveyor which are agitated or tumbled by the action of the moving conveyor belt. At least one rejecter hook is provided to ensure proper positioning of the plates within the pocket. As the conveyor belt progresses towards the upper end of the frame, certain plates are oriented properly within the plate pockets and will be conveyed to the upper end of the frame through the movement of the conveyor belt.Type: GrantFiled: October 26, 1990Date of Patent: August 13, 1991Assignee: Oak Industries, Inc.Inventors: Dennis J. Cotic, John L. Thorson

Patent number: 4974518Abstract: A machine for automatically setting rail tie plates includes a frame adapted to be propelled along a rail bed having one or both rails removed, the frame including a hopper adapted to store a plurality of randomly oriented plates therein, a crane for transferring plates to a plate sorting conveyor which sorts the plates as to specified length-to-width orientation and deposits the oriented plates upon an inclined conveyor where they are sensed as to specified top-to-bottom orientation, with improperly oriented plates being automatically inverted; the sensed and inverted plates are then manually disposed as to proper high-to-low side orientation, from where they are stored for eventual automatic deposition upon the tie by a reciprocating pusher assembly.Type: GrantFiled: August 1, 1988Date of Patent: December 4, 1990Assignee: Oak Industries, Inc.Inventors: Dennis J. Cotic, John L. Thorson
