Remington Portable lifting tray fitting (and a stop)

Now that the ribbon mechanism is back in place on the 'lost cause' machine, the lifting tray is the only thing still missing from the typing mechanism. The Remington Portable typewriter has a lifting mechanism, pushing back a knob on the right-side of the machine lifts the typebars to the typing position (as is very well documented on the net).

Hadn't yet mounted the sideplates to the segment that hold the crescent-rods or fulcrum-wires in place. These also have the mounting eyelet to pivot the protective hooks about. When mounting these plates, you'll want to play with the shifting of the carriage to get access for the screw. (Or mount this before assembling the ribbon shaft, of course...)


Some rubber-band is helpful in keeping the typebars out of the way during the procedure. Not clearly shown in the below image, but on the right can be seen one of the flimsy looking push-bars that do the lifting of the tray and in the lower-right the hex-nut of the uppercase-right shift adjustment.


Another preparing step on this machine was to fit one of these shift-stops.

A Remington Portable has four adjustable stops for the carriage shift, this machine was missing one of these stop-assemblies completely. These stops are mounted on the inner sides of the machine frame. The trapezium-shaped 'vane' is part of the carriage-shift link and travels between these two stops.


The stop assemblies consist of the stop-block itself, two mounting screws, eccentric adjustment-nut and a spring-washer. Luckily the spare-parts box contained a full extra set of these parts. (Just not in nickel-plate - this 'lost cause' machine must have been a sight when new - everything was bright shiny metal!)


There are thus two screws for each stop accessible from the outside to adjust the shift, that is what the cut-outs in the side of the outer frame/housing are for. This way the machine can be adjusted with only removing the top panel to get access to the eccentric hex nut.


Back to fitting the lifting tray; with the typebars out of the way the lifting tray can be lowered into its guides (B) and then fixed to the lifting bars (at A). Opening the bracket at the end of the lifting bars can be a bit fiddly. In this case with a badly mangled typewriter it also needed some forming to make it all meet up again.


 The 'hook' part that protects the typebars is then fixed to the tray and the segment endplates (C).


Unleashing the typebars again, these rest against the felt rim of the lifting tray and can be raised and lowered by the knob at the side of the machine. In the lowered position all the typebars rest flat on the lifting tray.


Except the '6' key.  (Drat.)

The linkages of the '6' key had been rather bent and the connecting rivets broken. The repaired linkage is apparently almost right, but takes a little too much space and won't go as far down as the others. Will be seen how to deal with this, it may be resolved raising the lower position of the tray a little. Something to have a look at with the machine more completely assembled. Not yet declaring it a 'lost cause' completely :-)

  1. Don't you just love it when one of the type bars wants to stand out from the crowd? That is going to be one nice typewriter when you are done. I can't wait to see the results of your work.

  2. These are amazing typewriters, with so much mechanism crammed into such a small space.

  3. Ah, hadn't looked at it that way - the 6 underscores its personality :-)
    Started on this one with the idea to give it a fancy paint-job, but first just getting it operational again is a (slow) project. The engineering on this one is impressive, especially if you picture it next to a contemporary Remington '10' standard. They basically crammed a '10' into a quarter of the space!
