S N A P - S H O T S from the PROCESS of RESTORATION

BURROUGHS  CLASS-1  ADDING / BOOKKEEPING MACHINE

The "BURROUGHS-LOCK" was removed - NO KEY necessary!
BUT HOW to lift the GLASS-COVER ???
[1st] The "PRINTING-LEVER" has to be unhooked from back side ...
( This is possible when the crank is pulled & hold !)



[2nd] Push the CRANK backward and pull it out of its axle.
Now lift the GLASS-COVER.

The PRINTING-UNIT is REMOVED because RUST & MISSING PARTS.
After Cleaning & Oiling
Have a "Look-Around" the nacked Adding Machine ...











The DISPLAY (= SubTotal ) shows 7 DIGITS ...



BUT behind the cover are 9 FIGURE WHEELS ...



... The RIGHT 7 DIGITS show the CONTENT of the ARITHMETIC UNIT
- The TOTAL-KEY deletes only the right 7 digits -
( The LEFT 2 DIGITS are ignored !)
The LEFT  2   I N P U T   FIGURES are used for printing an ID

The MISSING REPEAT-Key ...



... is home-made out of a CABLE CLIP soldered on a BRASS WASHER,
glued on a PLASTIC CHIP and covered by an INSULATION PIPE ...



The STAND has down a HANDLE to choose ...



either movable ON ROLLERS or FIXED ...



The HINGE of the DOCUMENT-HOLDER was broken - Now HOME-MADE
with a circular sheet-metal to cover the damaged wood area ...



BELL & HAMMER of the PRINTING UNIT is missing ...



... the "Paper-End"-BELL can be made out of a LADLE ...

PARTS of the the missing/broken HAMMER ...



Now soldered a STEEL WIRE with a PUSH-PIN-TIP ...



... and this is a DETAIL VIEW of the restored unit ...



R E M A R K :
The SCALE was loose & warped and had to be flattened by
using an electric iron with low temperature - than glued in place.
