A clean typewriter is a happy typewriter.

Cameron Kopf, are you reading? 

Last week I received from Germany this gorgeous Gossen Tippa (B).

It is a beautiful machine with a very responsive action. However, it had one quite serious flaw. It skipped and skidded about the place like a bar stool seems to under you, after you’ve sunk a few too many beers – or if you’re inclined as I am, red wines or vodkas.

Cameron Kopf’s Gossen Tippa B was also suffering from the skiddies as well, so he may be interested to read this.

I was able to type on on the Tippa, but every so often it would just fly off a few spaces. I popped off the base and a bit of a look underneath, but I couldn’t seem to really diagnose exactly what the problem was. Despite that, I still tapped out the typecast for my last blog entry quite happily – even with the skipping skidding problem occurring

I figured out the operation of the space bar escapement dog, but I couldn’t quite see why it kept happening. A few days later while I was riding to work, a thought occurred to me… This may not actually be a parts failure.

A few people had suggested that they needed to bend back parts with some needle nosed pliers, but all the parts in my escapement looked perfect. Not only that, they had been serviced at some point by someone who had used loctite to hold the tiny nuts in place – which implied it was in the last decade or so.

So…. with a few cotton-buds, I ventured into the inner sanctum of the Tippa; the escapement. 

The space escapement dog is the piece to the right. You can JUST make out the star gear. 
The star gear locks between two escapement parts. One of these is rigidly bolted to the escapement dog, the other part is a moving, spring loaded wedge that catches the star gear and does the bulk of the work. The star was skidding past both of these when the problem was occurring.
The outside, machine seemed incredibly clean – which I think led me to a false sense of security about it’s mechanical cleanliness. I learned otherwise when I managed to filthy up 8 tips of the cotton buds just inside the escapement dog  and along the star gear.
 The one on the far left was dipped in de-greaser.
Cleaning the prongs and the dog arms seemed to yield almost instant results. I flipped the machine over and gave it a whirl, and it seemed to have become dramatically more reliable and responsive. 
The lower wedge of the dog that moves needed a little bit of coaxing to hold into place. I jammed an on-hand set of pliers onto it to stop it moving, however the same result could have been achieved with a small screwdriver. 

I sprayed the escapement dog with a little de-greaser, and then wiped it away. I then dipped the cotton bud into a little cup of de-greaser and then proceeded to clean all the parts to make sure I had cleaned everything off. I gave the escapement a bit of a blast of air to try and clear any other muck that was left in place.

I then pushed a brush across the teeth of the escapement rack to move out some muck that I had observed had wedged into place.

After I fastened the bottom of the machine back into lace, I fed some paper in and gave the machine a good run. There was no observed skipping that occurred when I used the space bar,  and you could feel that it was catching with much more certainty.

The thing about machines like these, is that the parts are very small and fine. The escapement sits under the ribbon vibrator, and any particles of dust or ink that wishes to fall down from here during operation of the machine will lodge right into the escapement. And if you oil these parts, you will no doubt have problems too. Essentially the star gear had become so slipper that with the build up on it – it was just forcing itself to skid past the escapement parts. 
So there it is. It seemed incredibly simple – just ‘clean’ the parts, but really that’s all it is. I’m pretty confident that the skidding is sorted. Go me! I’ve got a couple of other little things to sort out on this Gossen Tippa as yet, but it is shaping up to be a very nice little machine.

Now…. for a little bit more Massive Attack….

  1. clean machine is indeed a happy machine. thanks for the Massive Attack, I had forgotten how much I like them – kind of lost track after Tricky left.


  2. I wonder if this method would work on my QDL? And “Unfinished Sypathy” is one of the top five songs of the '90s, as far as I'm concerned. Remove Shara Nelson's brilliant vocals and you're still left with music that would not feel out of place in a spy movie. Absolutely brilliant.
    Nice work with the Tippa, Scott!


  3. Greetings, Scott! Yes, I did read this very helpful post on the Gossen Tippa, and am very grateful for the information.

    I sent my Tippa to Ken Coghlan awhile ago to see what he could do about the skipping problem, and will direct him to this post.

    Thanks for sharing. I'm very glad that you figured out the issue and that your Tippa is working well!


  4. This was definitely to be my first move with Cam's Tippa. Thanks for showing me the success of it! Now, if I could just muster up the time and enthusiasm to actually FINISH it…

    Very helpful, Scott. Thanks for the post.


  5. I think cleaning the escapement on the QDL would yield results, as they are all very filthy. Mind you, they're all filthy because the escapement on that era of Royal portables is so damn hard to get to. I agree with your sentiment on Unfinsihed Sympathy, and I just with there was more out there of this quality! Spy movie? I like your thinking.
