Abstract

This article describes an object detector and holder which not only detects the presence of an object but, if the object is present, will hold it in a fixed position while it is being processed. In this case it comprises a plate 10 to which there is affixed a hollow cavity housing 11 containing a spool 13 which has a hold-down extension 14 affixed thereto. The hold-down extension 14 passes through an opening 15 in the housing 11 so that it may contact and hold an object 16 which appears to be detected and held in a fixed position. The cover 10 is provided with port 17 which is connected to the interior of the housing 11. The spool 13 is provided with a small pass-through bleeder port 12 which extends through its entire length.
