Telegraphs
Click on photo for larger picture.
These are the type of telegraphs that use powerful
electromagnets (two about an inch in diameter and 2 inches
long) to drive a pen or pencil (these use inked rollers)
onto a moving strip of paper driven by clockwork, thus
marking the paper with the dots and dashes of Morse code.
H. Wetzer Land Line Telegraph.
Circa 1880
Used at a Bolivian Railway Station. This telegraph shows a
mastery of several arts. The clockwork and woodwork are
true examples of artistic and engineering skill. In the
case of this telegraph the paper is marked by an inked
roller.
M. Kipp Land Line Telegraph.
Circa 1880?
Made in Neuchatel Switzerland, home of many fine clockwork
companies.
The following telegraph is NOT part of the Mangold
collection
Hasler (of Berne) Swiss Railway Telegraph
More than 100 years ago Gustav Adolf Hasler took over the
Swiss Federal Telegraph Workshops in Berne, which had been
set up to install reliable communications connections
between Switzerland's main cities. With his partner
Heinrich Albert Escher, he co-founded Hasler & Escher,
a company which initially specialized in the manufacture
and repair of Morse telegraph equipment. Soon, however,
the company extended its field of activity to research and
development in the field of precision measuring
instruments and registration equipment. Shortly before the
death of Albert Escher, ownership of the company was
transferred to Gustav Adolf Hasler. After the death of
Gustav Adolf Hasler in January 1900, his son Gustav took
over.1
