Patent number: 11850686Abstract: Present invention teaches a height adjustable rest having four main parts: a base, a cylindrical knob, a cylindrical post and a snap ring. The cylindrical post has a vertical straight groove to guide the up-and-down height adjustment when the knob is turned relative to the base. The base holes and the knob holes, along with the corresponding rods, provide increased torque when larger and/or heavier workpiece is being supported. The matching inner thread portion (on the inside of the cylindrical knob) and the outer thread portion (on the outside of the base) is a desired feature to make the product less susceptible to damages or work debris compared to other products with exposed threads.Type: GrantFiled: February 10, 2020Date of Patent: December 26, 2023Assignee: Valtra Inc.Inventors: Gary Tsui, Daqing Zhu

Publication number: 20100151984Abstract: There is provided transmission module (10) for a tractor which is selectively configurable between a CVT arrangement and a multi-ratio powershift transmission arrangement. The module comprises an epicyclic unit (13) in which a first gear element of the epicyclic is driven mechanically from the input shaft (11) and a second gear element of the epicyclic acts as an output of the transmission module. By simply connecting either a CVT unit (24) or a pair of clutches (80) between the input shaft and a third gear element the module (10) can be converted to the desired transmission arrangement. This delivers benefits in a factory for example whereby a large proportion of the assembly can be completed before tailoring the transmission to a customers requirements, thus reducing lead times on delivery.Type: ApplicationFiled: May 16, 2008Publication date: June 17, 2010Applicant: Valtra IncInventors: Ville Viitasalo, Timo Ruokola

Patent number: 7009480Abstract: A semi-releasable magnetic tool is disclosed. The tool comprises two magnetizable pole plates. Each of said pole plates is bounded by peripheral edges. The pole plates are spaced apart and preferably disposed in substantial registry with one another. A generally non-magnetizable spacer member is positioned between the pole plates and spaced inwardly from the peripheral edges. A magnetic switch is mounted between the pole plates. The switch is switchably associated with at least one magnetic element. The magnetic element positioned so as to magnetize the pole plates. The magnetic element can be switchably moved toward and away from the pole plates so that they are strongly or weakly magnetized. The magnetization of the tool in the weaker configuration is such that the tool can be easily placed in a desired position on a magnetizable workpiece. The tool is clamped in position on the workpiece by moving the magnet(s) closer to the pole plates.Type: GrantFiled: October 17, 2002Date of Patent: March 7, 2006Assignee: Valtra, Inc.Inventors: Gary Tsui, Daqing Zhu

Patent number: 6983525Abstract: To align the edges of plates prior to joining them, a generally cylindrical anchor member is spot welded at one location on one of its rims to a plate. A mounting element of a clamp body member slidably engages the anchor member. A force applicator element of the clamp body member is generally laterally spaced from the mounting element. The mounting element includes a generally arcuately extended semi-cylindrical socket portion of such a diameter that it slidably and snugly mounts the socket portion thereon. The rim portions of the anchor member provide a plurality of spot mounting locations for breakably spot welding, brazing or otherwise temporarily attaching the anchor member to a plate or other substrate. At least one of the force applicator or mounting elements is adapted to the incremental application of aligning force on adjacent plates. The body of the clamp bridges between the respective plates that are to be brought into line with one another.Type: GrantFiled: January 5, 2004Date of Patent: January 10, 2006Assignee: Valtra, Inc.Inventor: Peter Moreno

Patent number: 6893012Abstract: A cantilever clamping device capable of clamping work pieces of variable sizes and shape is equipped with a quick release button at its fixed arm to release the threaded rod and hence the work piece. The Quick Release Cantilever Clamp utilizes a fixed arm and a movable arm with floating pads to clamp the work piece. Clamping action is achieved by turning the threaded rod, one end of which is connected to the movable arm and the other end is attached with a turning handle. Both the fixed arm and the movable arm are designed to have clamping teeth on the curved inner edges to clamp large size cylindrical work pieces and the floating pads are for smaller size cylindrical work pieces and work pieces of different shape and sizes. The fixed arm is equipped with two holes for attaching the optional base block to mount the clamp on a work surface.Type: GrantFiled: May 23, 2003Date of Patent: May 17, 2005Assignee: Valtra, Inc.Inventor: Harry Wong

Patent number: 6860475Abstract: A clamping device allows welding, or other application of three-axis workpieces by providing X, Y, and Z clamping surfaces. The device is equipped with three mutually perpendicular base plates and on one of which a floating right-angle head is mounted through a threaded shaft with quick acting button for rapid advance and return. Inserts like leveling pads can be inserted to the tooling holes in the floating right-angle head to increase working access, especially at the joint area where the X and Y axes meet. A Z-axis attachment including base plate extension with clamping arm and a threaded shaft is mounted by screws to two of the base plates. The clamping arm of the Z-axis can be swung away for easy removal of the workpiece after work. The outside walls of the base plates are machined flat and square so that the angle clamp can be laid sideway to hold a workpiece vertically in place.Type: GrantFiled: July 1, 2003Date of Patent: March 1, 2005Assignee: Valtra, Inc.Inventor: Harry Wong
