The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

Abstract: A lower drill tool that is structurally configured to receive a bracket, and, to cooperate with an upper drill tool having a pair of spaced apart drill bits. The lower drill tool has part receiving surface, a pair of spaced apart drill bores, a central bore, a centering nub and a biasing member. The drill bores extend downwardly away from the part receiving surface. The central bore is between the drill bores and extends downwardly away from the part receiving surface. The centering nub is slidable within the central bore, and has an upper tip extendable beyond the part receiving surface, positionable between an extended position and a partially retracted position. The upper tip has a conical configuration. The biasing member is positioned within the central bore and biases the centering nub toward the extended position. A drill system and a method are also disclosed.

Abstract: A method and rivet apparatus to rivet a workpiece comprises an upper riveting portion and a lower riveting portion. The lower riveting portion comprising a fixed base, support member, and a pin assembly. The pin assembly comprises a center pin, a forming pin, a first biasing member, an outer shroud, and a second biasing member. The center pin pushes against a tail of a rivet to deform the tail of the rivet. The forming pin, fixedly coupled to the support member, pushes against the tail of the rivet to deform the tail of the rivet. The first biasing member, disposed below the center pin, biases the center pin through the forming pin and away from the support member. The outer shroud encircles the forming pin and the center pin. The second biasing member, disposed below the outer shroud, biases the outer shroud away from the support member.

Abstract: A fastener welding apparatus having a frame assembly, a welding assembly, a coupling assembly and a locating assembly. The welding assembly has a welder frame and a welding electrode assembly coupled thereto. The coupling assembly has a suspension frame, a frame axle and a welding axle. The frame axle is fixedly engaged to the frame assembly and the welding axle is fixedly engaged to the welding assembly. The suspension frame is pivotably coupled to each of the frame axle and the welding axle. The locating assembly is structurally configured to selectively allow the suspension frame to pivot relative to the frame axle and the welding axle.

Abstract: A fastening system including a frame, a movement control assembly, a fastener drive assembly and a collar presenting assembly. The frame can be coupled to an outside structure, for example, with a part that is to be coupled with a fastener attached to the frame. The movement control assembly is configured to controllably move the fastener drive assembly relative to the frame and the part so as to grasp the collar of the fastener, engage the threaded pin of the fastener and to threadedly engage the two structures together. The collar presenting assembly presents a collar of a fastener to the fastener drive assembly.

Abstract: A hydraulic system maintains squareness while extending an object via two lift cylinder assemblies. A hydraulic circuit is connected to the cylinder assemblies, and includes synchronizer with multiple isolated chambers corresponding to the cylinder assemblies, a rod extending axially through the chambers, and pistons mounted on the rod and associated with the isolated chambers. The hydraulic circuit operably connects a pump to the synchronizer and to the cylinder assemblies for controlling and providing synchronized movement of the cylinder assemblies. The hydraulic circuit includes valving for an automatic re-synchronization cycle, fill cycle, and air purge cycle. The system is effective for moving large objects in a non-binding manner, such as an extendable room on a recreational vehicle, while maintaining accurate squareness.

Abstract: A lift table maintains levelness while lifting a support surface via two or more lift cylinder assemblies. A hydraulic circuit is connected to the cylinder assemblies, and includes synchronizer with multiple isolated chambers corresponding to the lift cylinder assemblies, a rod extending axially through the chambers, and pistons mounted on the rod and associated with the isolated chambers. An axial passageway extends continuously through the rod and is connected to first passageways for communicating hydraulic fluid to one side of the chambers. The hydraulic circuit operably connects a pump to the axial passageway of the synchronizer and to second passageways connected to the chambers and to the cylinder assemblies for controlling and providing synchronized movement of the at least two lift cylinder assemblies. The hydraulic circuit includes valving for an automatic re-synchronization cycle, fill cycle, and air purge cycle.
