Latest Patents

One of Longacre's latest patents is a joint restraint assembly designed for connecting pipe ends together or to other objects. This assembly features a body that encircles the pipe, with multiple cavities adjacent to the pipe. Each cavity contains a segment that is configured to fit securely. The design includes one or more threaded bores that extend through the body into each cavity. A threaded bolt is used to engage the segment in that cavity, pre-loading it against the pipe during assembly. This innovative design allows for self-actuation of the segment under mechanical or pressure loading, ensuring that the assembly can accommodate high levels of mechanical loading and internal pressure without relying solely on the initial pre-load force from the threaded bolt.
