SUBSTITUTED FOR MECHANICAL CLUTCH ON THIS DEVICE. CHIEF RQMT OF 

MAGNETIC CLUTCH WAS THAT IT MUST NOT SLIP. DESCRIPTION Of DEVICE: 

(1) MOTOR CURRENT REDUCED TO BELOW 1¢jJ VOLTS STABILIZED AND 

CONTROLLED ON 5¢ CYCLES. 

(2) 2 REGULATED SPEED MOTORS 1 TO TURN DISK ANO 1 TO TURN CYLINDER 

(3) 1 SWITCH STARTS BOTH MOTORS AT ONCE.

CONSTANT SPEED ESTIMATED AT BETWEEN 25¢¢ TO 75¢ RPM. 

(5) GEAR TRAIN ADJUSTABLE TO 4 SPEEDS TURNS CYLINDER. 

(6) 1 STARTING POSITION fOR DISK 

(7) CYLINDER ADJUSTS TO APPROX 8 DIFFERENT STARTING POSITIONS 

(8) NO MECHANICAL CONNECTION BETWEEN DISK AND, ELECTRICAL 

CONNECTION POSSIBLE BUT ~YER HAD NO OPPORTUNITY TO TRACE

ON SURFACE OF CYLINDER VERTICAL RCWS Of" CONTACTS AVOIDED AT LEAST 

ON VISIBLE SIDE OF' CYLINDER 

(11) PLATINUM TIPPED METALIC BRUSHES LONG ENOUGH TO TOUCH CONTACTS 

WERE rtXED BY SCREWS INTO IRREGULARLY SPACED NOTCHES ON HORIZONTAL 

BAR ABOVE CYLINDER. 

(12) WIRES FROM THESE BRUSHES WERE LACED INTO A CABLE WHICH MEYER 

HAD NOT TRACED 

(13) MEYER THOUGHT IT UNLIKELY THESE BRUSHES COULD BE SHIFTED EXCEPT
