Abstract
Abstract A segmented, quick connect nut held together by a resilient ring. The segments spread apart to slip over a threaded bolt or stud. The base of the nut is conical and is mounted against an associated washer having a conical seat to receive the base and jam the segments together whenever the nut is tightened upon the bolt. The nut has a conical cavity at the head end, opposite the base, and the conical seat of a holding tool engages this cavity to facilitate spreading the segments whenever the nut is being threaded into position upon the bolt. A removal tool spreads the segments to remove the nut from the bolt once it is loosened from its seat in its associated washer.

Claim 1
Independent Claim
362 words
A fitting tool for a quick-connect fastening device for attachment to a threaded bolt or the like for securing members together, said fastening device comprising: a. a threaded nut having a generally cylindrical body divided longitudinally into a plurality of segments, with a threaded passageway sized for said bolt extending longitudinally therethrough and with wrench flats formed on the outer surface of said body whereby the nut may be turned with respect to said bolt, said body segments being held in juxtaposition by resilient retaining means disposed in a circumferential groove formed around said body outer surface whereby said segments may be spread apart to allow the nut to pass over a portion of the threads of said bolt without turning; b. said body means further including a conical seat formed at one end of the body means for engaging a nut seating means, said conical seat being coaxial with said threaded passageway; c. a nut seating means arranged to be disposed on the threaded bolt so that the seating means is between said nut and a member to be secured, said nut seating means including a member having an aperture extending therethrough, said aperture being sized to receive a portion of said conical seat, and having a seating surface arranged to mate with said body conical seat whereby as the nut is rotated on the threads of said bolt, the conical seat will be forced against the edge surface of said seating means causing the body segments to be held securely in position around said threaded bolt to provide a rigid fastening connection; and d. a conical socket at the end of the body opposite the conical seat, which is coaxial with the said threaded passage-way; and wherein said fitting tool is arranged to spread the body segments for inserting said nut over a portion of the threads of said bolt without nut rotation and said fitting tool includes a body having a frusto-conical projection formed at one end and a tubular bolt-receiving passageway extending inwardly from the said projection end and coaxial with said frusto-conical projection, said frusto-conical projection being insertable into said conical socket to spread the body segments.

A fitting tool for a quick-connect fastening device for attachment to a threaded bolt or the like for securing members together, said fastening device comprising: a. a threaded nut having a generally cylindrical body divided longitudinally into a plurality of segments, with a threaded passageway sized for said bolt extending longitudinally therethrough and with wrench flats formed on the outer surface of said body whereby the nut may be turned with respect to said bolt, said body segments being held in juxtaposition by resilient retaining means disposed in a circumferential groove formed around said body outer surface whereby said segments may be spread apart to allow the nut to pass over a portion of the threads of said bolt without turning; b. said body means further including a conical seat formed at one end of the body means for engaging a nut seating means, said conical seat being coaxial with said threaded passageway; c. a nut seating means arranged to be disposed on the threaded bolt so that the seating means is between said nut and a member to be secured, said nut seating means including a member having an aperture extending therethrough, said aperture being sized to receive a portion of said conical seat, and having a seating surface arranged to mate with said body conical seat whereby as the nut is rotated on the threads of said bolt, the conical seat will be forced against the edge surface of said seating means causing the body segments to be held securely in position around said threaded bolt to provide a rigid fastening connection; and d. a conical socket at the end of the body opposite the conical seat, which is coaxial with the said threaded passage-way; and wherein said fitting tool is arranged to spread the body segments for inserting said nut over a portion of the threads of said bolt without nut rotation and said fitting tool includes a body having a frusto-conical projection formed at one end and a tubular bolt-receiving passageway extending inwardly from the said projection end and coaxial with said frusto-conical projection, said frusto-conical projection being insertable into said conical socket to spread the body segments.
Claim 3
Dependent Claim
92 words
In the device defined in claim 1, wherein: a socket is formed in the end of said tool having a diameter larger than the diameter of said nut body means with the inner edge of said socket contiguous with the base of said frusto-conical projection; and a resileint retaining ring positioned about the inner periphery of said socket whereby as the frusto-conical projection of said tool is inserted into the conical socket of said body means the body segments will be spread and held in the expanded position by the retaining ring.
Claim 4
Dependent Claim
76 words
A quick-connect fastening device as defined in claim 2, wherein: said nut seating means is an oversized washer, and said fitting tool further includes a second socket sized to fit the outer diameter of said washer and arranged outward of said first socket, said second socket is provided with a second resilient retaining ring whereby the washer as well as the expanded nut may be retained in the fitting tool for insertion over the threaded bolt.
