Does Anyone Know How Vintage Ebonite Prints Are Made?

[fountainpen51]

I searched the web but I did not find anything about the prints in ebonite, how the factories put their name or the typical ripples in the black ebonites like the one in the photo, I guess it would be with a specific machine? Maybe with heat?

Does anyone know anything about this data?

Thanks

That was done by machine turning. Old big machines, analog in programming.

The method of putting decorative lines on hard rubber pens is called chasing. The pen in your photo is a CBHR pen, chased black hard rubber. You could find out more by going to Richard's Pens, http://www.richardspens.com, and do a search for chasing.

Can be called BCHR...also.

 

Guilloche machines are now rare....I was watching some German TV program, nd they were showing a 200 year old one that was still in use....and the comment was they are very very rare.

That is the chasing on the war time cap....war time in it has the indent for a cap ring but don't have one....so your cap was made before May of 1943.

Some watch makers still use guilloche machines. I have seen a Youtube or something on the net were they showed it....perhaps in making a silver pen....I think that was in Pfortzheim, the jewelry making capitol of Germany.

 

The other pictures are ones I made at Thomas's (Kaweco on this com) museum.....in they wouldn't let him put in an industrial gitter second floor, because some drunken fool climbed up on a pool monument and fell to his death. So less than half of what Thomas a real scholar of local area in and around Heidelberg, which was once the pen capital of the world.

Machinery collected just by him........from before Parker started the pressed boring cheap plastics with the P-51.

Some of the colored bars of celluloid (? could be something else) used on a couple of the drilling machines, to make pens.

 

I don't know what this does, but suspect it has to do with nibs.

Another mystery machine

???? some sort of press...don't know....

 

another different press & different tools under that

 

One of the machines used to drill out single bodies.

 

 

 

For making more pens all at once....two views, front and side.

 

Oddly, I got almost no resonance when I had showed his museum last year when I was on randsombucket...two or three comments only.

At 'home' Thomas has even more machines..............including a a man high, pallet wide nib making machine with dies of various companies.

He had to fight City Hall for years to get the museum.

Thank you very much everyone, I found on Richard's website, it seems that the machine was used with a black diamanetes and later the laser was used.

Thank you.

I remember that Yard o Lead displayed a working machine at the London Pen Show (can't remember if it was last year or the year before).
