摘要: A system and method for measuring an inside diameter of a pipe to determine if it exceeds a predetermined value using a plurality of fingers operatively connected to a spring. When in a fully extended position, the distance between opposite fingers is the predetermined value. The fingers are pivotable between a starting position, through the fully extended position, and to a failing position. In the starting position, an outer end of each finger engages an inside surface of the pipe to compress the spring. If the diameter exceeds the predetermined value as the system moves through the pipe, the pipe inside surface will no longer engage the fingers, which releases the spring causing the fingers to pivot to the failing position, where they remain until the system is removed from the pipe and manually reset.

摘要: A multi-functional knitting tool bracelet is disclosed. The invention is comprised of a bracelet assembly worn around the wrist of a user and is configured with a plurality of linked, square members having imperial and metric graduations and indicia. Said members having various apertures to cut yarn, receive crochet needles of differing diameters as well as stitch markers therein. One end of the aforementioned bracelet having apertures adapted to receive and selectively secure a crochet hook and a tapestry needle—and another end configured with a counting mechanism to record stitches and rows heretofore. The bracelet is joined around a user's wrist by means of an adjustable, magnetic clasp. Objectives of the invention include aiding the process of knitting, crocheting, quilting, tapestry projects and the like by having popular tools within reach at all times. Specifically, an onboard ruler enhances measuring and can be laid flat against a fabric or substrate; the apertures allow for proper needle selection based on gauge diameter; additional apertures hold stitch markers at the ready; apertures on one end store extra needles and hooks; and a distal end houses flush, counting disks that can be turned with the fingers such that they keep track of stitches and rows etc. Having these onboard tools allows a user to work more efficiently by minimizing pauses normally associated with having to reach for commonly used equipment.
