Claim 1
Independent Claim
249 words
A fastening device for threadably connecting a nut and a bolt, in which a noncircular washer is disposed on the shank of the bolt between the nut and the bolt head, comprising: housing means; a spindle rotatably supported on said housing means; driving means drivingly interconnected to said spindle for rotating same; socket means connected to and driven by said spindle, said socket means having a socket formed therein for engagement with a nut for threading the nut along a bolt; washer-engaging means mounted on said housing means for engaging a noncircular washer disposed on said bolt and for rotatably holding said washer relative to said housing means whereby to at least partially counteract the reaction force imposed on said housing means due to said nut being threaded onto said bolt; said washer-engaging means including a tubular washer-engaging member concentric with and disposed substantially in surrounding relationship to said socket means, said washerengaging member having a recess therein of noncircular cross section whereby said washer is adapted to be disposed in said recess for nonrotatably connecting said washer and said washerengaging member; and one-way release means interconnecting said washer-engaging member to said housing means for permitting rotation of said washer-engaging member relative to said housing means in one rotational direction for permitting said washer-engaging member to be selectively rotatably displaced into proper alignment with said washer for permitting engagement therewith, said oneway release means preventing rotation of said washer-engaging member relative to said housing means in the opposite direction.

Claim 3
Dependent Claim
246 words
A fastening device for threadably connecting a nut and a bolt, in which a noncircular washer is disposed on the shank of the bolt between the nut and the bolt head, comprising: housing means; a spindle rotatably supported on said housing means; driving means drivingly interconnected to said spindle for rotating same; socket means connected to and driven by said spindle, said socket means having a socket formed therein for engagement with a nut for threading the nut along a bolt; washer-engaging means mounted on said housing means for engaging a noncircular washer disposed on said bolt and for rotatably holding said washer relative to said housing means whereby to at least partially counteract the reaction force imposed on said housing means due to said nut being threaded onto said bolt; said washer-engaging means including a tubular washer-engaging member concentric with and disposed substantially in surrounding relationship to said socket means, said washer-engaging member having a recess therein of noncircular cross section whereby said washer is adapted to be disposed in said recess for nonrotatably connEcting said washer and said washer-engaging member; connecting means drivingly engaged between said washer-engaging means and said housing means for normally preventing relative rotation therebetween; and release means coacting with said connecting means for disengaging said connecting means to permit said washer-engaging means to be selectively rotated in one direction, either clockwise or counterclockwise, relative to said housing means for enabling said washer-engaging means to be properly aligned with said washer.
Claim 4
