Technical drawings are scaled to to ensure that all the necessary data for producing an object is provided to the manufacturer. In the case of small objects, like a typewriter, drawings are scaled up. In the case of large objects, like a skyscraper, it's the opposite.

I've never seen technical drawings for a typewriter, but it's safe to assume that typeface drawings were part of a set of drawings, each with their own specifications that told the manufacturer not only how to make the individual parts, but how to assemble them properly. There is too much math involved to go over here, but I can imagine that the scale of the typeface drawings had to include precise dimensions and angles in relation to other drawings, like for the carriage or the platen for example, so everything would function properly when they came off the assembly line.

Btw, you got me thinking. I would love to own a set of technical drawings for a typewriter. They would look super dope framed and hung my office. I think I'll keep my eyes open for some.

Apologizes if I was not clear enough. I am so wrapped up in this topic that the question for me was clear.
M.Höhne, you gave (partly) the answer I was looking for. The technical drawings for the typefaces used on typewriters are mostly 50 times bigger than the actual type on the typewriter itself and contain the necessarily measurements. I also figured that the 50:1 scale had to do with the details, so thank you for you support of the theory I had about it. I could find no source to quote. Is there any?
And why would the scale by 50:1? Why not 40:1? They were reduced by a pantograph to make the matrices. The pantograph could handle any reduction, or am I wrong?
In advance I would like to apologize for my written English.

Sorry, I don't get it. This goes to a new members page.

This is common knowledge. For a source, look first in Introduction to Engineering or Introduction to Drafting manuals.

Why not 40:1? Now you're being arbitrary. It was the decision of somebody who was in a position to make that decision and he made it. Maybe it was the tools at his disposal that day. 50:1 seems like a lot to me, too, but so does 40:1.  Let us see what you're looking at. Your post implies that you have several different drawings, possibly from different manufacturers

Yes, a pantograph can handle any reduction---or enlargement---within its physical limits. They were made in many different configurations for many different purposes.
