Abstract
A method of forming a joined pair fo wedge-action-type lock washers, wherein each lock washer has a cam surface and an oppositely disposed friction surface, the pair of washers being arranged so that their cam surfaces are installed in a juxtaposed face-to-face engagement, at which time the two lock washers are selectively joined together in such a manner as to allow lateral movement between each washer when rotational force is applied during the tightening of an associated fastening device.
Claims4
A method of forming a single lock-washer unit composed of a pair of mating lock washers, comprising the steps of:
- forming a pair of washers, each having a frictional surface and an opposing cam surface;
- applying a releasable securing means to the cam surface of at least one washer thereof, said releasable securing means comprising a bonding material that allows the mating washers to be freely separated by the relative rotational forces applied to said washers;
- mating the opposing cam surfaces of each of said washers to form a signle lock-washer unit;
- said cam surfaces comprising a frontal cam wall and a rearwardly inclined cam surface;
- wherein the opposing frontal walls are spaced apart to allow movement therebetween;
- and
- selectively applying said bonding material to at least one inclined cam surface.
A method of forming a single lock-washer unit composed of a pair of mating lock washers, comprising the steps of:
- forming a pair of washers, each having a frictional surface and an opposing cam surface;
- applying a releasable securing means to the cam surface of at least one washer, said releasable securing means comprising a bonding material that allows the mating washers to be freely separated by the relative rotational forces applied to said washers;
- mating the opposing cam surfaces of each of said washers to form a single lock-washer unit;
- said cam surfaces comprising a frontal cam wall and a rearwardly inclined cam surface;
- wherein the opposing frontal walls are spaced apart to allow movement therebetween;
- and
- selectively applying said bonding material to the outer peripheral walls of said washers.
A method of forming a single lock-washer unit composed of a pair of mating lock washers, comprising the steps of:
- forming a pair of washers, each having a frictional surface and an opposing cam surface;
- applying a releasable securing means to the cam surface of at least one washer thereof;
- and
- mating the opposing cam surfaces of each of said washers to form a single lock-washer unit;
- wherein said releasable securing means comprises a bonding material;
- and
- wherein said bonding material is a glue that permits the mating washers to be separated when rotational force is applied thereto.
