Abstract
Official abstract text for this publication.
In accordance with certain embodiments, the present invention provides a theft-deterrence device, which can be used to deter theft of oil-and-gas equipment. For example, one such embodiment provides a nut-and-bolt assembly that includes an extended bolt and a standard the hexagonal nut. To deter theft, the exemplary assembly includes an outer sleeve that is disposed about the nut and extended bolt and that is free to rotate. Resultantly, the sleeve prevents the application of torque to the nut and also protects against shearing of the extended stud. The exemplary assembly also includes a tamper-resistant screw extending through the stud and cooperating with a retaining ring disposed above the nut, to prevent removal of the outer sleeve.
First claim
Opening claim text (preview).
The invention claimed is: 1. A theft-deterrence device, comprising: a sleeve surrounding a tool interface of a bolt assembly, wherein the sleeve has a shoulder located on an interior surface, and the sleeve is free to rotate with respect to the tool interface; a retaining ring disposed above the tool interface, wherein the retaining ring is configured to cooperate with the shoulder to block removal of the sleeve; and a retaining pin that extends through a bolt of the bolt asse…
