Abstract: A lock pin assembly used for clamping two plates together, that have aligning bores for receiving the lock pin assembly. The lock pin assembly includes radially extending pins that can be forced outwardly from the center of a lock pin housing forming a part of the lock pin assembly. The actuator pins are forced outwardly and cooperate with a tapered surface on a bottom plate to create a clamping force relative to an end of the lock pin housing supportable on a top plate. The lock pin housing has cam tracks on an outer side thereof, and an actuator ring surrounds and supports the pin and carries cam followers sliding in the cam tracks. The cam tracks are made such that relative rotation of the lock pin housing and the actuator ring changes the axial location of the actuator ring along the housing.

Abstract: A five axis vise includes two separated vise body portions that are supported on a machine tool table or other support that fixes the vise body portions in position. The vise body portions have jaws spaced up from the machine tool table sufficiently to permit machining five surfaces of a work piece held in the jaws. A vise screw is rotatably mounted in one of the vise body portions, and extends to the other vise body portion to actuate a movable jaw on the other vise body portion. The vise screw is threaded into a jaw nut that has a drive surface that engages and drives a driven surface on the movable jaw, with the drive and driven surfaces being inclined relative to the axis of force application to provide a downward force component on the movable jaw as it is tightened. The vise screw is an assembly of a threaded shank or shaft and a hub that is rotatably mounted in one of the body portions, with the threaded shank or shaft being locked in position in the hub.

Abstract: A bicycle trainer is adapted for use with a bicycle. The trainer includes a base and a frame having spaced apart ends adapted to engage and support the bicycle. A pivoting assembly is joined to the frame of a central portion of the frame and to the base. The pivoting assembly allows movement between the frame and the base and includes a biasing mechanism that resists tilting of the frame relative to the base. The frame is supported only by the pivoting assembly.

Abstract: A locking mechanism includes a tube and a rod slidable with respect to the tube. A driving mechanism is adapted to engage the rod to provide movement of the rod relative to the tube and a locking mechanism is used to lock the rod in a locking position.

Abstract: Two station vise for manual or hydraulic operation with a quick-change stationary that can be carvable, hard or reversible. the stationary jaw having two precision through holes is placed on expanding pins, located on the top longitudinal rails of the vise body, that precisely position and tighten the stationary block in place. Two movable jaws connected by a tubular drive form an axially adjustable floating assembly. A manually turned tubular drive has an external threaded screw to move simultaneously the first jaw/nut and an internal thread that moves the second jaw/nut, on the opposite side of the stationary. Hydraulically parts are clamped at the two stations with a piston located in the second jaw/nut and connected axially with the first jaw/nut by the tubular drive. A setup-block located at the front jaw/nut keeps both jaws at proper position for loading and unloading of parts. The setup-block also allows for pre-clamping or retention of the part in the rear station before clamping.

Abstract: The material compactor generally includes a feed apparatus and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having confronting compression plates and an adjustably taperable portion. The area of the inner cavity of the final compaction chamber can be adjusted to become measurably smaller (tapered) or larger at the opened discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the chamber significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus and out an open discharge port.

Abstract: Pin lock assemblies are provided for a stationary vise jaw of a double vise two support surfaces of the vise rails. Each pin lock assembly has a pin housing that is threaded into a first bore in the respective vise rail, and which seats in a known position. Each pin housing has an outer end with a pair of oppositely facing generally conical surfaces, one of which mates with a conical surface at an outer end of the aligned first bore in the vise rail, and the other of which is an outer cone surface extends above the vise rail support surface. A slotted expanding sleeve is mounted over the outer end of the respective housing and has a mating, inwardly tapered interior cone surface to mate with the outer cone surface of the housing. Each pin lock assembly further includes a separate cone end collar that acts against a cone surface at an outer end of the slotted sleeve to cause the slotted sleeve to expand.

Abstract: A locking pin system for clamping a fixture plate onto a receiver plate using locating pins that pass into aligning bores on both the fixture plate and the receiver plate. Each locating pin has a cylindrical body with a flange or head on one end and a cone surface at the other end. An axially slotted sleeve with two internal cones is provided in the bore of the receiver plate. A screw with a cone nut is passed through the locating pin so that the nut is on the opposite end of the slotted sleeve from the locating pin. When the cap screw is tightened, one end of the slotted sleeve engages a cone on the pin and the other end of the slotted sleeve is engaged by a cone surface on the nut, to expand as it moves in direction toward the flange and lock the slotted sleeve in place in the bores of the receiver plate. The flanges or heads of the locating pins engage the outer surface of the fixture plate and as the cap screw is tightened, the flanges or head will force the fixture plate against the receiver plate.

Abstract: The material compactor in accordance with the present invention generally includes a feed apparatus, a preliminary compaction apparatus, and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having an adjustably taperable choke tube. The area of the inner cavity of the final compaction chamber can be tapered to become measurably smaller or larger at the discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the tapered choke tube significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus.

A rotating member is joined for rotation with the rotatable shaft. The rotating member is external to the sealed chamber and is magnetically coupled to the impeller.

Abstract: A bearing assembly is mounted onto the shaft of a rotating wheel of a bicycle exerciser, wherein the rotating wheel is driven by a person on a bicycle. The bearing assembly is loaded so that the inner and outer portions of the bearing assembly are urged in a manner to create a drag on the bearing assembly that is transmitted to the rolling wheel.
