Abstract
Official abstract text for this publication.
A locking member for a fastener, such as a nut or a collar, includes a shank portion and a flanged portion, a bore extending the shank portion and the flanged portion and including a first interior portion located within the shank portion and a containment cavity located within the flanged portion, and an inner wall defining the containment cavity. The containment cavity includes an inner diameter that is greater than an inner diameter of the first interior portion of the bore. The inner wall of the containment cavity includes one or a combination of flat/linear surfaces, concave surfaces, and convex surfaces.
First claim
Opening claim text (preview).
What is claimed is: 1. A locking member, comprising a first end, a second end opposite the first end, a shank portion extending from the second end to a location intermediate the first and second ends, a flanged portion extending from the shank portion and to the first end, a bore extending from the first end to the second end and including a first interior portion located within the shank portion and a containment cavity located within the flanged portion and proximate to the first end, and an inner wall defining a containment cavity, the containment cavity including an inner diameter that is greater than an inner diameter of the first interior portion of the bore, wherein the inner wall of the containment cavity includes a first concave surface located proximate to the first interior portion, a second concave surface located proximate to the first end, a cylindrical surface intermediate and joining the first and second concave surfaces, and a conical surface joining the first concave surface with the first interior portion. 2.
