Abstract
A safety device for automatically preventing an injectile propelled within a pipeline having a terminus from inadvertently escaping the pipeline at a coupling point. The safety device automatically engages upon decoupling, thereby safe-guarding the pipeline operator and surrounding area from injury and/or damage due to injectiles that have been previously injected within or passed through the pipeline and that could otherwise inadvertently escape the pipeline upon decoupling. A preferred embodiment of the present invention comprises a base, means for clamping and means for automatically halting the progress of the injectile. One embodiment of the present invention further comprises means for horizontally positioning the means for automatically halting the progress of the injectile, means for vertically positioning the means for automatically halting the progress of the injectile and means for displacing the means for automatically halting the progress of the injectile. The claimed invention also contemplates a means for situating the base on a pipeline terminus such that the base is in the optimal position with respect to the coupling point.
