Abstract: A locking fastener assembly comprising a fastener having a threaded portion, and a head having a first end and a second end axially spaced from the first end, the second end comprising a fastening surface and a locking washer recess. The locking fastener assembly further comprises a locking washer disposed at least partially within the locking washer recess, the locking washer comprising a locking tab extending in a first direction and a stop biased in a second direction opposing the first direction, wherein the locking tab is operable to lock rotation of the locking washer relative to an item being secured upon a torqueing rotation and a loosening rotation of the fastener. A locking member is supported by the fastener, and operable to interface with the stop of the locking washer upon the loosening rotation of the fastener to lock the fastener relative to the item being secured.

Abstract: A mounting structure for mounting a first member and a second member on each other forming a device such as a cooling fan or the like. The mounting structure is equipped with a rubber joining member provided between the first member and the second member, having a curing property and joining the first member and the second member, and a first metal member provided on the first member on a side opposite to the joining member and having an elastic force restricting the relative movement of the first member to the second member.

Abstract: A linear compressor is provided that may include a shell including a refrigerant suction inlet, a cylinder provided in the shell, a piston reciprocated in the cylinder, a suction muffler movable together with the piston, the suction muffler defining a refrigerant passage, a suction guide provided at one side of the piston to guide a refrigerant suctioned through the refrigerant suction inlet to the suction muffler, a back cover coupled to the suction guide, and a coupling guide provided in a space defined by the suction guide and the back cover to maintain a coupling force between the suction guide and the back cover.

Abstract: A tapered compression ring for flared tube applications includes a generally ring-shaped body having (a) a gap defining a first end and an opposite second end, (b) a first face, (c) an opposite second face, and (d) a central axis. The first face is tapered at the first end, and the body is twisted so that the first end is offset from the second end along the central axis in a direction away from the first face.

Abstract: A connector housing (10) has supporting walls (14) and support shafts (21) project in from the inner side surfaces of supporting walls (14). A lever (30) has arms (32) disposed inwardly of the supporting walls (14). Bearing holes (33) formed in the arms (32) are mounted rotatably on the support shafts (21). The arms (32) try to move wider apart upon the engagement of cam grooves (34) on the arms (32) with cam pins (Mp) on a mating connector (M). However, the arms (32) are displaced in directions to move the bearing holes (33) from the projecting ends toward the base ends of the support shafts (21). Therefore, engaging areas of the bearing holes (33) and the support shafts (21) are not reduced.

Abstract: A present invention provides a locking mechanism capable of preventing a bolt from loosening. A bolt 5 has a head provided with a first part which comprises openings 511. A locking washer 4 is provided with a second part which includes outer projections 411 and a third part which includes insertion projections 401 on an outer edge. A taper piece 1 has a portion provided with a fourth part which comprises openings 105. The first part and the second part can engage with each other and the third part and the fourth part can engage with each other when said bolt 5 fastens at least two members 7 and 8 trough said washer 4 and said taper piece 1. Accordingly, the bolt 5 is prevented from rotating in an loosening direction.

Abstract: A fastening device (20), for use in holding a base plate down to a railway sleeper. The device is of the type having a head portion (21), a screw-threaded shank portion (22) and an intermediate portion (23) connecting the head portion (21) to the screw-threaded shank portion (22), with the intermediate portion (23) and the screw-threaded shank portion (22) being of smaller diameter than the head portion (21).

Abstract: An assembly of a bolt, a washer, a nut and locking structure for locking the bolt against rotation after the bolt, washer and nut have locked together a pair of flat, plate-like members in frictional engagement with each other. Any tendency for the bolt to rotate in a reverse direction will be prevented by the locking means. The plate members will essentially be bonded together against movement relative to each other, thereby maintaining structural integrity of the assembly. In a first embodiment, the head of the bolt has a notch for receiving one end of split ring washer. The other end of the washer is in a notch in the nut. The nut and washer define a locking unit for preventing reverse rotation of the bolt after the head of the bolt has been moved into proximity with the washer and the washer has been moved into the notch of the nut. Other embodiments are disclosed.

Abstract: Fastening devices such as washers, seals and drive pins subject to corrosive deterioration of all or select portions thereof wherein all or such select portions are protected from such corrosion and failure by a thin coating or coatings of hard surface material or materials. In a preferred form, the fastening device is coated with a synthetic diamond material formed as a thin layer in situ thereon. In addition to preventing moisture and other corrosive material from penetrating to the base metal, such synthetic diamond material serves to preserve the surface integrity of the fastening device preventing the formation or spread of surface flaws produced during use or during the fabrication of the fastening device.

Abstract: The present invention is a torque indicator device that provides a positive indication as to whether or not a threaded fastener has been tightened to a desired torque. The present invention torque indicator device is mounted under the head of a threaded fastener and is shaped so that the indicator device is displaced from beneath the threaded fastener's head as the threaded fastener is tightened to a predetermined torque. As the threaded fastener is tightened to a predetermined torque, the brightly colored indicator device falls away from the threaded fastener giving an easily observed positive indication as to whether the threaded fastener has been properly tightened.

Abstract: A workpiece fastening device usable on a machine tool fixture, comprising an elongated tubular body having knurling along the outside of the top end of the body, a taper on the inside thereof, and a plurality of slots extending longitudinally about half the length of the body. A lock washer with a yieldable portion is welded to the bottom end of the body to allow a workpiece to be pulled flush against a fixture. The tubular body is slip-fitted into a through-bore in the workpiece until the lock washer rests upon the fixture, and a bolt having a head taper matching the taper in the tubular body is then inserted through the body and is threadably received in the fixture. Upon tightening of the bolt, the top of the body expands causing the knurling to grippingly engage the bore in the workpiece. After the body is completely wedged in the bore, further tightening of the bolt causes the lock washer to be distorted slightly thereby allowing the workpiece to be pulled flush against the fixture.
