Driver For A Lobed Collar
US Patent:
4742735, May 10, 1988
Filed:
Apr 3, 1981
Appl. No.:
6/250895
Inventors:
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Pasadena CA
International Classification:
B25B 1306
US Classification:
811211
Abstract:
A driver has a deltoid wrenching and deforming socket in the form of an equilateral triangle with rounded corners. Flats of the socket between the apexes of the triangle bear on lobes of a collar to thread the collar onto a pin in the making of a joint. At a predetermined clamp-up load on the joint, the flats of the deltoid socket crush the lobes plastically and force material of the collar radially inward of the lobes into locking engagement with the pin. Thereafter the socket can rotate freely on the collar. A pilot section of the deltoid socket cooperates with a corresponding section of the collar to keep the driver from canting off axis. Reliefs with cylindrical surfaces in the sides of extensions of the flats define piloting surfaces of the pilot section.
Blind Bolt Fastener For Low Bearing Strength Materials
US Patent:
4203346, May 20, 1980
Filed:
Jan 5, 1978
Appl. No.:
5/867008
Inventors:
David E. Hall - Costa Mesa CA
Edgar L. Stencel - Huntington Beach CA
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Pasadena CA
International Classification:
F16B 1306, F16B 1310
US Classification:
85 70
Abstract:
A blind fastener has a nut with a threaded bore, a core bolt having external threads for receipt by the nut, and a sleeve for expansion by the head of the core bolt and a shoulder of the nut to form a blind side folded bulb against the backside sheet of a joint. A thin-walled, tapered section of the sleeve fits over a relieved section of the nut and bears against the shoulder of the nut. The taper is such that the thin wall increases in thickness away from the shoulder. An axially adjacent thick-walled section of the sleeve bears on the core bolt head and resists sleeve tuck-out over the core bolt head, concentrically aligns the sleeve on the core bolt, and assures that the thin-walled section of the sleeve is the section that bulbs. During setting, the sleeve expands by compression exerted on it by the core bolt head and the shoulder. The thin wall section folds against the backside sheet with an ever-increasing area as tightening continues.
Fastener Insert With Improved Anti-Rotation And Pull-Out Characteristics
US Patent:
4007659, Feb 15, 1977
Filed:
Feb 13, 1975
Appl. No.:
5/549562
Inventors:
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Pasadena CA
International Classification:
F16B 1310
US Classification:
85 70
Abstract:
A blind fastener system comprising a ductile sleeve having an expansion portion of small inner diameter in a thin workpiece and having a bulbing portion of larger inner diameter extending on the blind side of the workpiece, and a threaded expander member having an expander portion for expanding the sleeve expansion portion and a head portion for bulbously deforming the sleeve bulbing portion, both actions occurring on axially pulling the expander member. The expander portion has a tapered, radiused leading end followed by a configured (splined, knurled, etc. ) portion for the remainder of the active length. The protrusions of the configured portion leave a void volume between them and between the minor and major diameters of the protrusions, and the volume of the sleeve expansion portion between the small inner diameter and the projection of the large inner diameter is approximately 0. 5 to 0. 8 of the void volume of the configured portion. The protrusions have blunt outer surfaces.
Mechanically Locking Fastener
US Patent:
4067371, Jan 10, 1978
Filed:
Jul 15, 1976
Appl. No.:
5/705397
Inventors:
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Rosemead CA
International Classification:
F16B 3932
US Classification:
151 4173
Abstract:
A mechanically locking fastener has external threads for installation in the threaded bore of a workpiece. A lock ring has internal radial serrations locked in serrations of the fastener proper, and external radial teeth of a form for gripping the wall of the workpiece bore when turning moments tend to loosen the fastener and to pass over the bore wall upon rotation in the opposite direction. The lock ring has a slip plane to permit contraction of the ring to a diameter no greater than the major diameter of the fastener and expansion of the ring when the fastener undergoes moments tending to loosen it. The fastener proper may be a stud or an insert. An external chamfer of the ring bears against a cooperating internal surface of the workpiece to positively determine the axial location of the insert with respect to the workpiece.
Pin And Process For Its Manufacture
US Patent:
4544312, Oct 1, 1985
Filed:
Dec 24, 1984
Appl. No.:
6/685957
Inventors:
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Pasadena CA
International Classification:
F16B 3902, F16B 3928
US Classification:
411 3
Abstract:
A threaded pin has flutes along the threads formed by roll-forming threads over a preformed section having either flat sides or dished sides. The major diameter of the threads lies along ridge crests bordering the flutes, and the minor diameter of the threads lies at the base of the flutes. The threads extend along the major diameter in each of the ridge crests for a distance on an order of magnitude of the distance across the mouth of each flute. The preformed section is formed by extrusion. The flutes provide space for material from a threaded collar forced into them to provide a thread lock.
Self-Locking Fastener, Fastener System, And Process
US Patent:
4260005, Apr 7, 1981
Filed:
Nov 9, 1977
Appl. No.:
5/849756
Inventors:
Edgar L. Stencel - Huntington Beach CA
Assignee:
VSI Corporation - Pasadena CA
International Classification:
F16B 3902, F16B 3928
US Classification:
411 3
Abstract:
A collar threads onto a shear pin. When the collar engages a surface of a workpiece, resistance to further threading increases. When sufficient resistance to threading occurs, a setting driver upsets lobes of the collar and forces these lobes radially inward toward the axis of the collar. Material of the collar inside the lobes responds to deformation of the lobes and flows radially inward against the shear pin to lock the collar, shear pin and workpiece together. The driver then rotates freely and a joint has been made with a predetermined clamp-up load and its component parts locked together.
