    摘要： A sewing machine is provided for splicing together two different threads. The machine includes a thread tree with a number of thread spools with each thread thereof being inserted through flexible plastic tubing. A movable carriage assembly locates the new thread to be spliced relative to a splicing device passageway that receives the new thread to be spliced along with the old thread. The splicing device includes a front air inlet for drawing the new thread into the passageway of the splicing device and a rear air inlet for creating air turbulence during the splicing operation. Also used in moving the new thread through the passageway is an insertion drive roller connected to a pivotal rocker. A thread clamp cover connected to the rocker cooperates with the trimmer blades to trim the old thread. A thread clamp and a thread clamp magnet cooperate to hold the old thread in a desired position during the insertion of the new thread into the splicing device. A tensioning assembly is able to adjust new thread tension based on a desired tension for the new thread.

    摘要： A shield useful, in conjunction with an air gun with a medium conduit, in flushing debris from a blind hole. It comprises a case, an exhaust clearance, a hanger, a bottom clearance, and at least one guide with a clearance, and a plug useful for plugging an unused guide clearance. The medium conduit is inserted through a guide clearance which directs a medium, such as compressed air or nitrogen or liquid, towards the blind hole. The medium and debris from the blind hole flow out the exhaust clearance.
