Patent number: 7399139Abstract: 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: GrantFiled: July 21, 2005Date of Patent: July 15, 2008Assignees: Somero Enterprises, Inc., Michigan Technological UniversityInventors: Carl B Kieranen, Charles A Hallstrom, Glen R Simula, Nils P Ruonavaara, James D Waineo

Patent number: 7396186Abstract: A screeding device for screeding a concrete surface includes a support member, a screed head assembly mounted to the support member, and a control. The screed head assembly includes a grade setting device and a vibrating member, and is selectively movable in a screeding direction over and along the concrete surface by the support member. The vibrating member is vibratable to screed the concrete surface as the screed head assembly is moved in the screeding direction over and along the concrete surface. The control is operable to automatically stop vibration of the vibrating member when the support member is not moving the screed head assembly in the screeding direction and to automatically vibrate the vibrating member when the support member moves the screed head assembly in the screeding direction.Type: GrantFiled: February 9, 2007Date of Patent: July 8, 2008Assignee: Somero Enterprises, Inc.Inventors: Philip J. Quenzi, Carl B. Kieranen, Frank E. Anderson, Jeffrey W. Torvinen, Mark A. Pietila

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

Patent number: 7175363Abstract: 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: GrantFiled: April 14, 2006Date of Patent: February 13, 2007Assignee: Somero Enterprises, Inc.Inventors: Philip J Quenzi, Carl B Kieranen, Frank E Anderson, Jeffrey W Torvinen, Mark A Pietila

Patent number: 7144191Abstract: A contouring machine control system, contouring/smoothing method, and kit for enabling a contouring machine to automatically contour three-dimensional surfaces includes a contouring member, such as a screed or dirt grading blade, a target either attached to the contouring member or located at a remote location, a tracking device at the other of the contouring member or remote location that tracks the target and measures the position of the target in three dimensions, a proximity sensor adjacent one end of the contouring member to detect its height above a physical reference, and a controller/computer for controlling the height of the two ends of the contouring member. One of the ends is controlled as a function of a stored profile of the desired surface to be contoured and the target or tracking device position, while the second end is controlled as a function of the current height of the proximity sensor above the reference.Type: GrantFiled: January 21, 2005Date of Patent: December 5, 2006Assignee: Somero Enterprises, Inc.Inventors: Carl B Kieranen, Charles A Hallstrom, Glen R Simula, Nils P Ruonavaara, James D Waineo

Patent number: 7121762Abstract: 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: GrantFiled: July 29, 2004Date of Patent: October 17, 2006Assignee: Somero Enterprises, Inc.Inventors: Philip J.

Patent number: 5234281Abstract: A deflection indicating adjustable highway straight-edge. The highway straight-edge is designed to effectively level wet concrete by allowing the user to determine when the device is not straight and provides the user with a means of controlled adjustment for straightening.In the preferred embodiment, a laser light beam and electronic sensing device is used to detect deflection of the straight-edge. Undesirable deflection can be eliminated through the external adjustment of steel tension cables inside the straight-edge tube. In an alternative embodiment of the invention, deflection is detected by means of an electrically conducting wire having contact points to indicate that the straight-edge requires adjustment. In another embodiment, a steel wire or string line stretched tightly inside the straight-edge tube indicates deflection requiring adjustment.Type: GrantFiled: January 15, 1992Date of Patent: August 10, 1993Assignee: Somero Enterprise, Inc.Inventors: David W. Somero, Paul J. Somero, William W. Niemela, Philip J. Quenzi

Patent number: RE39834Abstract: A contouring device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by a pair of fluid cylinders. The fluid cylinders are controlled to raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of one of the fluid cylinders is based on a comparison of the measured position of a first end of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. The measurement of the position of the first end of the contouring assembly is achieved by a tracking device which tracks the position of a target positioned on the first end of the contouring assembly and which determines the three dimensional position of the target.Type: GrantFiled: May 6, 2003Date of Patent: September 11, 2007Assignees: Michigan Technological University, Somero Enterprises, Inc.Inventors: Carl B. Kieranen, Charles A. Hallstrom, Glen R. Simula, Nils P. Ruonavaara, James D. Waineo
