Please see all my other typewriter feet at: class=\"MsoNormal\" style=\"font-size: large; font-family: Arial; line-height: normal;\">\"Flat Top Rear Foot\" option means one set of 4 feet, with flat-topped rear feet
\"Raised Back Top Rear Foot\" meansone set of 4 feet, with raised back rear feet
\"Front Feet Only\" means just that, 2 front feet, this was asked for, I suggest you replace all 4 feet!
Thislisting is for a set of 4 replacement typewriter feet (or two front feet) which will fit a varietyof Underwood typewriters marked as \"Universal\", \"Champion\",or possibly neither and commonly referred to as \"Underwood 4 Banks\".But, please study this listing closely, Underwood (like othermanufacturers) changed design details and foot designs frequently. Here youmust pick from two design options depending on your machine. Please closelyread this listing, and examine my photos and diagrams to confirm which one (ifany!) will fit your machine. The front feet are the same for all covered modelyears (if yours looks like the photos). The two options are only about the rearfeet, which are very similar but slightly different. Basically these are foryour machine if from the 1920\'s or 1930\'s only, and:
1.Ifthe rear feet are NOT against the back of the machine, but an inch or sotowards the front, you want the \"Flat Top Rear Foot\" option
2.Ifthe rear feet ARE against the back of the machine, you must choose theappropriate option. Look closely at your machine and my photos:
oIfthe mounting flange extends to the very back of the machine (or within a couplemillimeters), you want the \"Flat Top Rear Foot\" option\", asthere is no room for the raised back option to fit.
oIfthe mounting flange is inset a bit further (at least 4mm), you can use the\"Raised Back Top Rear Foot\" option, which extends up in back to hidethe mounting flange. It should be possible to fit the \"Flat Top RearFoot\" on these machines as well, but it will not look as nice from therear due to exposed flange and larger gap.
3.Ifyour original rear feet are intact, it may be obvious which type you need fromthe original (if not squished).
Thesetypewriters originally had rubber feet that by now may have the properties ofchewing gum under a desk. Even if they look ok, they probably have no tractionat all, so the machine will slide around making typing difficult. Mine were thelatter, enabling me to make very good measurements of their rather complicateddesign. These are replacement and much improved feet using modern 3D Printingtechniques and materials, I think they look and function better than theoriginal rubber ever could have, and will hopefully last a lot longer!
Myresearch indicates that these should fit on all the Underwood Universalmachines made through 1948 (from photo evidence on TWDB), and probably through1952. Basically, if your machine looks just like the mine in the photographs,they should fit. Pay particular attention to the foot style (if they exist onyours), or at least placement of the mounting points. The front and back feethave a completely different design, although look similar mounted. In thefront, they are to be pushed through large holes below the Back Space (left)and the *- (right). In the back--this is the key feature to identify that theseare the correct feet--they are flush with the back, and the shell has a cutoutmatching these feet so you completely can see them from the back (see photo).The back feet are mounted by inserting a screw through a washer on the bottom.Note that the front feet also have a hole in them, but this is for the post onthe case bottom to fit through.These machines probably need the “RaisedBack Top Rear Foot”. I believe the Tower Tabulator 603.10 machines will need these same feet.
Thereare similar looking machines marked “Champion”, which seem to hail from 1936 through about 1940. They probably need the “FlatTop Rear Foot”.
So,there are a bunch of other Underwood “4 Bank” machines that might say\"Universal\" on them, but they have different feet. There are even abunch grouped together in TWDB along with this machine under \"UnderwoodUniversal\" most of those are actually different machines, usually referred to as\"Underwood 4-banks\", for example tend to have a cutout front, and elegant logo ribbon covers. You can clearlysee from the rear photo that you can\'t see the feet, and they are different.The front feet are actually the same. These seem to need the “Flat Top RearFoot”, and seem to hail from the 1920’s through about 1936.
Idesigned these to be nearly an identical replacement, but with the advantagesof modern technology we can engineer materials that were previously impossible.I printed with NinjaFlex Black TPU (https://ninjatek.com/ninjaflex/), which isnearly indestructible in ordinary use(but a knife or scissors will cut it,just like rubber!), flexible, and pretty gripping on most surfaces. I printedthese at about 50% infill (with a flexible gyroid fill structure) for a balancebetween good friction on the table, tight fit on the machine and shockabsorption, and ability to easily install or remove them. These look andfunction just like the original, but should last much longer and be far moredurable. Some people may prefer the original dull rubber look, but I actuallythink these are a superior look to rubber, and the glossy sheen looks greataccenting the dark grey of the machine.
Idesigned these for my own typewriter as shown, and this is an experiment to seeif it\'s worth my time to make some more for the community. I typically share mydesigns for anyone to print, except for extremely difficult cases that I put alot of design hours into. This is one of those, front and rear feat arecompletely different designs with a ton of critical dimensions, it took manyiterations for each to get the design right. They also use more than twice theNinjaFlex material and printing time as my other feet, so I have to charge morefor them.
PS:\'s volume discount display is a bit confusing, each purchase is a SET OFFOUR feet, so picking \"1\" is one set of 4; \"2\" is 2 sets of4 (8), etc.
**PSS**Typewriters and mounting hardware shown in photos is for illustration anddisplay only, and is NOT included in this listing!! **
***Update*** Added an option on request to just purchase two front feet (the ones with the bulb on top that pushes through the hole in the frame). This is NOT recommended, you should really replace all 4 feet!
