DESIGNED AND BUILT AS PART OF JIM SWAIL'S PROGRAM TO DEVELOP AIDS FOR THE BLIND.
Function
To cover the end of a photo sensor to protect it when not in use.
Technical
ONE OF THE FIRST EXAMPLES OF SPECIALIZED LABORATORY EQUIPMENT CONSTRUCTED TO MEET THE NEEDS OF BLIND SCIENTISTS & ENGINEERS. SWAIL WAS FIRST EMPLOYED BY NRC IN 1947, AND BUILT THESE FOR HIS USE THEN. MCSHEFFREY DESCRIBED IT TO ME IN 1985 AS A "VOLTMETER" - "A REAL MUSEUM PIECE" DATING FROM C.1960, THE ONLY SURVIVOR OF A WHOLE SET OF METERING INSTRUMENTS THAT SWAIL BUILT BEFORE 1964 WHEN THEY STARTED TO MODIFY EXISTING INSTRUMENTS, SUCH AS THE SIMPSON METERS. BUT FROM THE LITERATURE THIS CLOSELY RESEMBLES THE ORIGINAL 1948 "RADIO MULTIMETER" (SEE PHOTO, ONLY HANDLE HAS BEEN ADDED LATER) AND THIS MAY IN FACT BE THAT ORIGINAL ONE.
