Hermes Ambassador Electric

This Ambassador has been with me for 35 years. It didnt work well and little grains of plastic came of it if it did. It had to wait in the attic for my retirement.
Alas, this Ambassador Electric has not survived its long storage. The powerroll is lined with Vulkollan polyurethane, which seems to degrade. expand and grab hold of all the single-stroke-clutches that are built around it
See the drawing (servicedoc courtesy of Jaap Horstink)

The donor machine that I bought suffered the same disease.
If the roller could have been refurbished to the exact size, the task of rebuilding the machine would be beyond my abilities, so I thought.

I have decided to disect both machines and donate their organs to art (see www.typischkunst.nl) and to engineering design, see their picture gallery.

No typeface sample, alas

Photos:

the black circle is the powerroll, continously driven by the electric motor (in CW-direction) The toothed elements with the white dots are two brakeshoes that just run free of the powerroll. When releasing the catch to the left, the element A is grabbed by the powerroll, It make one rotation, hitting the type-lever hard, is freed from the roll and caught behing the latch again

Overview of the servo type mechanism. The powerroll turns in CCW-direction. A, B, C and D are pivot point fixed to the machine. A, B, C and D are stationary pivot-points.

Typelace. 46 numbered typebars

segment with slot for pivot-wire. How is that slot machined?

links that require grinding them flat due to space requirement, see other photo

The spaceframe with the crossmember that carries the module with the linear slide to shift the the segment uo and down. the segment is up for the lower case, and down for the upper case.

The castings of the carriage, one sliding through the other

linear guides, steel plated surfaces

Aluminium as scrap metal?

the actual mechanism in the flesh

the links that need grinding to fit

the frame with some 44 links where the typemechanism hooks in

As a retired product development engineer, I am fascinated by the design of electro-mechanical products in which parts move, make noise and, preferably, radiate a little heat. Most preferred are products that are operated by keys, like typewriters, accordeons and pianos.
My genetics and statistics on lifetime expectancy suggest that it is time for me to let you know about the fantastic design, product engineering and manuacturing skills of the generation before mine. I salute mr. Munk for the opportunity that he has created for me to show it to the world. Okay, a bit bombastic.
