  • Patent number: 6212977
    Abstract: A spring chuck having a locking mechanism provided between two handles of the spring chuck. The locking mechanism includes a sleeve connected at an end to one handle of the chuck, a shaft having an end connected to another handle of the chuck and another end movably located in the sleeve via a lower open end thereof, a brake handle having a ring-shaped head put around the shaft and pivotally connected the lower open end of the sleeve, and a compression spring mounted around the shaft between the sleeve and the ring-shaped head of the brake. The compression spring normally pushes the ring-shaped head to pivotally turn away from the sleeve to frictionally contact with the shaft, preventing the shaft from moving in the sleeve and thereby lock the handles of the chuck to a fixed position. Pushing the brake handle toward the sleeve causes the ring-shaped head to align with the sleeve without frictionally contacting with the shaft and therefore allows the handles of the chuck to move freely.

  • Patent number: 6212995
    Abstract: A variable-displacement inclined plate compressor includes a crank chamber defined by a cylinder block and a front housing connected to the cylinder block. The cylinder block has cylinder bores, each opening toward the crank chamber. A rounded edge of each cylinder bore extends circumferentially around the cylinder bore at a crank chamber-side axial end of the cylinder bore. By the formation of the rounded edge of the cylinder bore, the sliding resistance of the piston may decrease. The decreased sliding resistance may prevent the piston coating from being scratched. Further, the decreased sliding resistance may decrease the load on the compressor, thereby achieving a smooth control of the inclination angle of the inclined plate.

  • Patent number: 6212997
    Abstract: Chromium nitride coating of machine components such as reciprocating pump plungers for continuous sliding contact with non-metallic packing and gasket materials greatly increases the performance life of fluid seals. In an air driven reciprocating constant pressure pump, exterior surfaces of the pump plunger are coated with chromium nitride to a thickness of seven to ten microns. The coating resists failure from repeated sliding contact against non-metallic packing and gasket materials for at least four million pump cycles, with no evidence of cracking or release of metallic particles which would embed in the packing or gasket material and score the plunger. In lower pressure pumps, interior walls of a housing against which a sliding gasket bears, when coated with chromium nitride, greatly increase the seal life of the sliding gasket.

  • Patent number: 6213000
    Abstract: An improved wobble piston and seal assembly for an oil free air compressor. The piston has a seal support surface which is provided with an upwardly directed curve adjacent its perimeter. A flat annular seal is secured to the piston to be supported by the support surface. The curve imparts a limited bend to the seal adjacent the perimeter of the piston. The piston and seal are then inserted into a cylinder which increases the bend to substantially 90°. The region of the bend in the seal adjacent the top of the piston is supported by the curved top to reduce flexing during operation at high air pressures. By preventing a reduction in the bend radius at high air pressures, stress in the seal at the bend is reduced, permitting use of a harder more durable seal material.

  • Patent number: 6213022
    Abstract: An improved cartridge of a type having a casing and a bullet with a tip expellable from the casing for entering a target. The improvement includes the bullet having a pair of throughbores bored through different levels thereof for causing the bullet to expand violently and over a wide diameter and mushroom halfway in the target so as to cause severe damage, destruction, and hemorrhage to internal organs of the target for a quick kill, with the mushrooming being regular up to a first throughbore of said pair of throughbores and then splitting causing not only a wider mushroom but a sudden extra shock to the target due to more energy transfer caused by more tissue displacement of the target due to the wider mushroom, and with the bullet then splitting again at a second throughbore of said pair of throughbores so as to further widen the mushroom for even more shock and damage to the internal organs of the target causing a quicker kill by virtue of the bullet expanding and peeling back to nearly inside out.
