Triumphator D
A relatively late Triumphator model - I initially skimmed over it in a listing of online advertisements, because it seemed "just another Triumphator". Only when accidentally clicking open the advert the next day I noticed it was the 12 x 12 x 20 model D.The issue with machines with large capacity is that in order to effect the tens' carry throughout the entire register, you need a large surface area on the pinwheel cylinder - because every numeral wheel must have the time to prepare the next higher digit for tens' carry before the tens carry pin arrives - and if your register is 20 digits long, this requires quite a bit of space. There is only one solution for this - you must make the pinwheel cylinder larger, so that the pins themselves take less surface angle, and the tens' carry pins have enough room to be able to operate. Look e.g. at the enormous Brunsviga D, which only went into production in a miniature version, which is still a lot larger than the other miniature machines. Thinking about this, I was expecting that the Triumphator D would be a bit larger than the model C.
And I wasn't disappointed - it is huge - in fact, it is just about the size of one of the old giant Triumphators, only all the controls and registers are relatively smaller.
The machine took a bit of cleaning, but is now looking resplendent again in its deep black livery. It is a shame though they stopped putting the image of the factory on the back of the machine.
And a comparison to make you appreciate the size difference with the Triumphator C.
And another comparison to show the C next to one of the big, old machines - some parts might well exchange between the D and these!
