20090072462Angle Bracket - An angle bracket formed of a block of material. It has an elongated upper arm member formed adjacent the top end of a connecting member and an elongated lower arm member connected to the bottom end of the connecting member. The rear surface of the respective arm members make a 90 degree angle with each other. The top surface of the respective arm members have a swivel pad recess and a plurality of locking channels extend radially outwardly therefrom for receiving the arm of a clamp. An alternative embodiment angle bracket is capable of adjustable angles. It has an L-shaped upper clamp arm that is pivotally connected to an L-shaped lower clamp arm. Each of these arms have a V-shaped support clamp portion formed at their free end.03-19-2009
20090189324Magnetic Positioning Device - A magnetic positioning device is disclosed and claimed wherein two magnetic arms are hingeably connected by an axle connector with locking bolt and nut, and an activation hole with pin inserting through the connection disks having arc-shaped toothed-groove made the selection of frequently used angles straight-forward and easy, when the pre-select angles are built to the “indents” in the toothed-groove, so that the enlarged head on the pin can be used to easily engaging to the selected angle, by pushing toward the spring located inside the hole on the disk. An optional switch is provided on the second end of the magnetic arm for easy control of the magnetic power direction.07-30-2009
20090205214Edge Level with Side Magnets and Velcro - Present invention provides an edge level that can be used for measuring angles or levelness on all X, Y and Z axis simultaneously and in hands-free type operation, due to the use of Velcro or external clamps used together with the features introduced herein. A removable pod, containing the Z-axis bubble, provides the flexibility of insertion to the pod seat for measuring Z-axis angle and can be stored or put aside when not in use.08-20-2009
20090283021Metal-top welding table - A welding table used in welding industry and woodworking applications comprises a metal table top with retractable carrying handle and elongated slots for insertion of clamping tools, a protrusion-adjustable angle flange with V-notch mounted to at least one edge of the table top, a support structure having an angle and height adjusting mechanism, and a foldable base frame with casters.11-19-2009
20100084799Single hand operated ratchet clamp - A single hand operated ratchet clamp comprises a finger ring lever and a typical ratchet clamp having a slide rail, a sliding arm, a fixed arm, and a lever element with pressure plate. The finger ring lever is pivoted to the free end of the lever element so that the ratchet clamp can be operated with one hand only. An alternate design is to make a finger hole on the free end of the lever element.04-08-2010
20100282133Modular Welding Table - Present invention disclosed and claimed a modular welding table where the work surface is made up of a plurality of plates that can be easily slided to and fro, adapting to objects of different shapes. The through holes on these plates, as well as the parallel grooves between these plates, provide the foothold for clamping tools and devices that are used in conjunction to this welding table, to secure the work piece in place. Under each of the leg, a height-adjustable pad is provided, so that the welding table can adjust its evenness accordingly, by turning the screw stem of the pad easily.11-11-2010
20100301533Tab Welding Bracket - Present invention provides a handy tool that can be used to facilitate welding job, where (second) work objects can be held on by the holding surfaces of the first positioning frame of the welding bracket; the first positioning frame is used to hold on to another (first) work piece between the generally v-shaped swinging foot pieces on the v-frame; the two swinging foot pieces can pivot on respective axle, allowing for adjustment to different size/diameter of first work piece, and the bolt and butterfly nut structure allows adjustment to be made between first positioning piece and the v-frame, for purpose of adapting to welding object of different thickness held on by the holding surfaces on the positioning frame.12-02-2010
