Patent number: 7448564Abstract: The invention includes a rock crushing machine and method, the machine having a base and a jaw assembly secured to the base. The jaw assembly is adapted to receive rock as input material to be at least partially crushed. The jaw assembly is provided with an arcuate reaction surface that progressively engages the input material. A hollow crushing roll has an axial inner chamber that has an axis of symmetry (O). The crushing roll is a driven member that has an outside surface which forms a crushing zone between it and the reaction surface of the jaw assembly. Positioned at least partially within the crushing roll, an eccentric shaft serves as a driving member. The eccentric shaft has an axis of rotation (E), that axis being displaced from the axis (O) by a distance (T). A drive mechanism is coupled to the eccentric shaft so that as the eccentric shaft turns, rotational and centrifugal forces can be transmitted to the crushing roll by a torque transmitting device or other roll drive torque biasing mechanism.Type: GrantFiled: August 4, 2005Date of Patent: November 11, 2008Assignee: New Dimension Crushers, LLCInventors: Robert Niemela, Carl Kieranen

Publication number: 20070140792Abstract: A soft landing control system for a screeding device is operable to automatically lower a vibrating member relative to a grade setting device after the grade setting device is lowered to the desired grade. The control may be operable to delay lowering the vibrating member relative to the grade setting device at least until the control receives an input indicative of at least a portion of the screed head assembly being moved to a position generally over a newly placed concrete area. Optionally, the control may delay lowering of the vibrating member relative to the grade setting device until a period of time has elapsed after an activating event. Optionally, the control may automatically stop vibration of the vibrating member when the screed head assembly is not moving in the screeding direction and may automatically vibrate the vibrating member when the screed head assembly moves in the screeding direction.Type: ApplicationFiled: February 9, 2007Publication date: June 21, 2007Applicant: SOMERO ENTERPRISES, INC.Inventors: Philip Quenzi, Carl Kieranen, Frank Anderson, Jeffrey Torvinen, Mark Pietila

Publication number: 20060216114Abstract: A soft landing control system for a screeding device is operable to automatically lower a vibrating member of a screed head assembly into engagement with a concrete surface at a time and place where the vibrating member is not positioned over an overlap area of already screeded concrete. The vibrating member is automatically lowered onto newly placed concrete at or near the junction or cold-joint between the already screeded concrete and the area of newly placed concrete, so as to avoid depressions in the already placed concrete. Optionally, the soft landing control system may include a timing device and may lower the vibrating member after a period of time following an activating event. Optionally, the control system may detect when the vibrating device is positioned at or near the newly placed concrete and may lower the vibrating member in response to such detection.Type: ApplicationFiled: April 14, 2006Publication date: September 28, 2006Applicant: Somero Enterprises, Inc., a corporation of the state of DelawareInventors: Philip Quenzi, Carl Kieranen, Frank Anderson, Jeffrey Torvinen, Mark Pietila

Publication number: 20050265785Abstract: A device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at two locations by height adjustment mechanisms that raise and lower the two locations of the contouring assembly independently of each other. The contouring assembly creates a three-dimensionally curved surface as it passes over an area to be contoured. The control of at least one location of the contouring assembly is based on a comparison of the measured position of one portion of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. Control of the height of the other location is preferably based on the height above a physical reference measured with a proximity sensor. A pivot or tilting controller may control the tilting of the contouring assembly to follow the slope of the profile stored in computer memory.Type: ApplicationFiled: July 21, 2005Publication date: December 1, 2005Applicants: Delaware Capital Formation, Inc., Michigan Technological UniversityInventors: Carl Kieranen, Charles Hallstrom, Glen Simula, Nils Ruonavaara, James Waineo

Publication number: 20050069385Abstract: A screeding apparatus for screeding and smoothing an uncured concrete surface includes a vibrating member and a grade setting device adjustably mounted to said vibrating member. The screeding apparatus may include a wheeled support which at least partially supports the vibrating member and/or the grade setting device. The grade setting device is vertically adjustable, such as via a laser plane responsive control system, to set or indicate the desired grade of the concrete surface as the screeding apparatus is moved over and through the uncured concrete. The level of the screeding apparatus may be automatically adjustable to maintain a desired level and angle of attack of the vibrating member. The vibrating member may be activated only when the screeding apparatus is moved in a screeding direction so as to reduce depressions that otherwise may occur if the vibrating member vibrates on the uncured concrete when not moving.Type: ApplicationFiled: July 29, 2004Publication date: March 31, 2005Inventors: Philip Quenzi, Russ Stein, Mark Pietila, Carl Kieranen, Philip Halonen, Howard Hohmann
