You may find yourself living in interesting times. The world we knew two months ago is gone, and there is time enough at last, to finally go through those projects we’ve been putting off for one reason or another. Today, I wanted to explore and possibly repair an old unidentified typewriter that belonged to my late aunt for many decades.
A small disclaimer though, I am not an avid typewriter collector or connoisseur. I enjoy looking at them and using them, but by no stretch of the imagination I want to claim to be an expert in their history or inner workings — I’m a hacker after all. What follows is a layman’s adventure into her first typewriter repair, an exciting tale that explores typewriter anatomy and troubleshooting. Let’s dig in.
The Typewriter and It’s Quirks
This is my late aunt’s typewriter. It’s missing the type cover, which I assume had the only identifying information on it, because other than a small plaque indicating the company which imported it into our country, the whole body has no branding whatsoever. I’ve looked online and asked a few people, none of them could place their finger on it and no other ultraportable typewriter I can find looks like it. What do you way, Hackaday, anyone know what I have here? At best we can place it as post-1940s, and it looks like maybe a Smith-Corona Skyriter, but has many differences to it.
I remember being allowed to play with this typewriter as a kid, long after it had been decommissioned from any important work it might have served in the past, and since then it has some new quirks too. Most glaringly, two accent keys were constantly in a slightly depressed state and pressing them all the way down didn’t move their respective type heads, which also idled in a wrong position. This was the most mind-boggling issue, and the one I was often told “couldn’t be fixed”, or “would be too expensive to take to someone to fix.” The other issue was that the upper and lower cases were misaligned, making any printed text look wonky if you tried to capitalize words.
Straightening Type Bars and Cleaning Gunk
The way mechanical typewriters like these work is by striking a type head through an ink-soaked ribbon onto a piece of paper. The type head has the embossed mirror image of the letter you want to type in it, and the action imprints it onto the paper with the ink from the ribbon. As you use the typewriter over the years, ink can start to clog the type heads and “dull” them out, causing blurry printing.
This is easily remedied by taking an old toothbrush soaked in isopropyl alcohol and scrubbing all the type heads until they’re clean. If you want to be thorough about it, you can do them one by one, but doing large strokes across all of them at once in their resting position cleaned mine enough for sharper letters.
These type heads have seen better days, between ink build-up and the two bars resting in an odd position.
As I tried typing with newly-refreshed heads, I noticed some of the type bars would get jammed at the end of travel. Looking at this website on typewriter restoration, which has been an invaluable resource throughout this whole ordeal, I found out the causes of that can include bent type bars and a gunked up segment (the piece that holds the type bars). Sure enough, with some gentle scraping of the slots with a fine screwdriver followed by ever so slightly bending the bars that continued to stick after that, all seemed in order. As far as the typing experience, this typewriter was already starting to shape up.
The Broken Keys
The two accent keys in their broken state seemed like the most daunting part of this restoration. I’ve been discouraged from attempting repairs on this typewriter at a younger age, but now there’s little care left for it and I was able to inspect them however I wanted.
At first, guided by whatever I could gather from other typewriter models online, I tried looking underneath the mechanism, looking for any links that might have broken. After removing the bottom cover I was surprised to find that this model was mostly entirely boxed up, allowing me little to no access to any of the keys through here. However, I did notice two missing bolts, which corresponded to the keys that weren’t held up in the right place. At first I thought this could be related…
If you look closely, you can see two missing bolts towards the right side.
… But then I found out these bolts are in place in order for all type keys to equally activate the mechanism which pushes the carriage forward one character. In the case of the two accent keys, these bolts are meant to be missing on purpose, making them what’s called “dead keys” so the accent can be typed without moving the carriage, and then a letter can be typed underneath.
You can see an unhooked link just behind the key it corresponds to. To get it back in place, you just need to wrench it out of the way a little and push them together so the pin on the key bar hooks into the slot of the type bar.
So I looked back up again, and noticed there was another plate behind the keys I could remove, and there I found the culprit. Right behind the keys themselves lies a row of springs which make part of the system that returns the keys to their starting position. Once I exposed the rest of the mechanism, I noticed the two broken keys had separated from their links to the type bars. Luckily, it was a simple matter of twisting a screwdriver between the bars and snapping them back into place in order to hook them again, and suddenly the keys were working after decades of negligence.
A Stiff Case of Improper Alignment
With the broken keys out of the way, the only thing that kept this typewriter from being in top shape was the fact that upper and lower cases were misaligned. If you look closely again at the picture with the type heads, you’ll notice each key has both their regular glyph and their shifted-position glyph on the same head.
The way typewriters change between one and the other is that the shift key on a typewriter literally shifts the entire carriage up so that the alternate glyph is printed on the page instead. For letters, that moves between upper and lower cases, with symbols it can be an entirely different symbol although the mechanical function is the same. Adjusting the resting and shifted positions of the carriage is what affects the alignment between both sets.
The carriage shift alignment screws for this typewriter. The top one adjusts the height of the resting position, and the bottom one adjusts the height of the shifted position.
Every typewriter is going to have a slightly different mechanism, so to find mine I just kept looking around near the carriage to see which parts moved while I moved it in and out of shift. On each side of the carriage, I found two screws, one which would remain fixed to the body and one which was part of the carriage as it shifted. The one that shifts hits against the body of the typewriter, determining its rested position. The other one hits against the carriage as it moves up, determining where it stops for the shifted position.
One last glamour shot of a happily working typewriter.
With that in mind, first I tried to adjust the height of the shift case, but no matter what I tried the screw wouldn’t budge. So instead I adjusted the lower case position of the carriage and aligned it to the upper case. Though that resulted in the carriage resting a little lower than normal and grazing part of the body (which already had skid marks on it and I wonder if that’s why someone misaligned it on purpose in the past), the text was now perfectly aligned.
The Wrap Up
With everything working perfectly, I started to put the shell back together on this typewriter. Although I realize I didn’t have to take off nearly as much of the cover to get to the parts I ultimately needed for this relatively simple restoration, I’m glad I did it, for it gave me a newfound appreciation for this machine. It also made me reflect on how easy it is to dismiss yourself or others from attempting to learn how something works or how to repair it just because it looks complicated and daunting. Sure, most of us on Hackaday might not be so easily dissuaded, but if it weren’t for my continued interest with this machine to this day, it might still have been sitting in my mom’s storage surrounded by cobwebs and lost memories.
