Back to the Typewriter Overview |
REMARKS: *************************************************************************** This Model is an interesting "MATHEMATICAL" Version (Custom made ? ) It has special symbols on the hammers ("+", "=", "π" & "square-2") but the "standard" symbols on its keys ... Modified TECHNICAL DATA of this newer Model: ============================================ o Pica 10 cpi ; 80 cpl o Shift keys added on the right side o Carriage-return / line-feed handle on the left side o Carriage extended one inch, now 9 3/4 " (Now fitting business envelopes) The Trick with RIBBON SPOOLING: =============================== When operating right, both axles of the ribbon spools turn clockwise. Both spools have to have the ribbon-ends wound up counter-clockwise. THE RIBBON TURNS AROUND THE SPOOL WHICH HAS THE TOP-NUT FIXED - THE OPPOSITE NUT HAS TO BE LOOSE - in order for the ribbon to move ... RESTORATION Starts: ******************* Nothing was working. Discovered after disassembling, that someone with low skills and bad tools had tried to repair - OhOh! (1) Cleaning, bending, oiling, re/placing springs ... (2) End-lever of the space-bar lever-system was broken ... ----> Temporarily repaired by glueing a hook made of copper-wire! (3) Missing a special screw on the left side of the carriage for holding a ratchet lever in place - enables the rubber- cylinder to go back to previous lines ... ----> Made "the right one" out of a longer screw! (4) 12 (too small) ball bearings supported the carrier ... ----> Found 8 right ones ( 3/16" ) to exchange! (5) To prevent clustering of the ball-bearings ... ----> Made a cage out of paper clips! |
