Filed:

Jan 14, 2004

Appl. No.:

10/757759

Inventors:

Jack R. Kerr - Desoto TX, US

Assignee:

Loc-Mor, Inc. - Mansfield TX

International Classification:

F16B039/34

US Classification:

411303, 411247

Abstract:

A lock nut having a locking ring with a spoon-shaped lug. The lock ring includes a nut body having a bore with an interior threaded portion and a substantially cylindrical recess coaxial with the threaded portion of the bore. The recess includes a single notch on a portion of the recess. In addition, the lock ring includes a threaded locking ring positioned within the recess. The locking ring is deformed when threading the bolt onto the lock nut to frictionally grip the bolt. The locking ring also includes a single projecting lug at one side only of the locking ring, which fits into the notch to prevent relative rotation between the ring and the nut body. The lug includes a bowl-shaped nodule for collecting shavings gathering within the threads of the bolt and the interior bore of the lock nut.

Jack Kerr - Desoto TX, US

International Classification:

F16B 39/22

US Classification:

411280000

Abstract:

The present invention is a flex lock nut. The flex lock nut includes a hexagonally shaped nut body having a threaded bore. In addition, the nut body includes a collar portion formed by six slotted segments mounted on an upper end of the nut body. The collar portion has a smaller diameter than the nut body. On a bottom opposite end of the nut body is an annular recess located on a perimeter around the bore. When the flex lock nut is seated upon a thread bolt, the lock nut provides two locking features. First, while threading the nut upon the bolt, the slotted segments expand to provide a conventional upper locking feature. In addition, as the flex lock nut is continually seated upon the bolt, the annular recess deforms, thereby provide a novel second locking feature.

Assignee:

Lok-Mor, Inc. - Arlington TX

International Classification:

F16B 3934

US Classification:

411302

Abstract:

A method of forming a lock nut and the product thereof in which a coaxial extension is secured to the end face of a standard nut to receive a locking element therein. The extension is comprised of a concentric metal ring secured at one edge to the end face of a standard nut and at the other edge secures a locking element against the end face of the nut.

International Classification:

US Classification:

10 72R

Abstract:

A heavy duty press mechanism, whose ram is driven by means of an eccentric crank and pitman, carries a head with four aligned indention punches for distorting thread pitch simultaneously on four axially aligned hex nuts. A feed track system feeds a row of axially aligned hex nuts under the punch head. A reciprocating ejector-stop, synchronized with the punch ram, simultaneously ejects a group of four indented nuts and defines a stop for the following group of nuts at the indention station. A feed system includes an axial feed track for feeding nuts to the indention station, a lateral feed track, and a transfer speed coupler coupling these tracks. A vibrating hopper feeds laterally aligned nuts into the lateral feed track, where a single row of side-by-side nuts is fed by gravity to the speed coupler. The speed coupler effects a transfer from lateral feed to axial feed into the axial feed track. Air jet means initiates the axial feed of nuts in the speed coupler; and a vibrator associated with the speed coupler contributes to the smooth, fast transfer of nuts from lateral feed to axial feed.
