Channeled spirit level having spirit vials adjustably mounted within the channel thereof

Abstract

Abstract IN A SPIRIT LEVEL COMPRISING AN ELONGATED CHANNELED FRAME DEFINED BY A WEB PARALLEL SIDE WALLS EXTENDING PERPENDICULARLY FROM ONE SURFACE OF SAID WEB, WITH ONE OF SAID SIDE WALLS EXTENDING BEYOND SAID WEB TO PROVIDE A FLANGE DISPOSED PERPENDICULARLY TO THE OPPOSED SIDE OF SAID WEB, MEANS IS PROVIDED FOR ADJUSTABLY MOUNTING SPIRIT VIALS IN CONNECTION WITH SAID WEB IN A MANNER TO BE COMPLETELY HOUSED WITHIN THE CHANNEL OF SAID FRAME. THE MOUNTING MEANS INCLUDES A BASE MEMBER OF TRANSPARENT PLASTIC MATERIAL DETACHABLY SECURED TO THE WEB PORTION OF THE FRAME AND HAVING A SPIRIT VIAL RECEIVING RECESS IN THE OUTER FACE THEREOF, AND A TRANSPARENT PLASTIC COVER MEMBER OVERLYING SAID BASE MEMBER HAVING RESILIENT MEANS FOR FIRMLY SUPPORTING A SPIRIT VIAL IN CONNECTION THEREWITH IN A MANNER TO BE POSITIONED IN SAID RECESS AND SPACED FROM SAID BASE MEMBER. THE COVER MEMBER IS DETACHABLY SECURED TO SAID BASE MEMBER IN A MANNER TO PROVIDE LIMITED ROTATION OF THE COVER MEMBER FOR ACCURATE ALIGNMENT OF THE SPIRIT VIAL. IN ONE SPECIAL ADAPTATION OF THE INVENTION OF SECOND SPIRIT VIAL IS MOUNTED WITHIN THE RECESS OF SAID BASE MEMBER BY RESILIENT MEANS SECURING THE SAME TO SAID BASE MEMBER AND ADJUSTABLY BY LIMITED ROTATION OF THE BASE MEMBER. IN ANOTHER SPECIAL ADAPTATION A SECOND VIAL IS ADJUSTABLY MOUNTED ON AN EXTENSION ALONG ONE SIDE OF THE BASE MEMBER AND ORIENTED PERPENDICULARLY TO SAID WEB, AND SAID EXTENSION SUPPORTS AN ANGLED MIRROR SO POSITIONED THAT THE FIRST VIAL AND THE MIRROR IMAGE OF SAID SECOND VIAL ARE IN SUBSTANTIAL ALIGNMENT.
