Getting round again to tinkering with the 'lost cause' Remington Portable 2 typewriter, the next step after mounting all the typebar linkages was the ribbon mechanism.
The change of ribbon travel direction is done by sliding the shaft to the left or right, engaging either of the spool holders with its conical drive gear. To keep it in engagement, there is a spring loaded mechanism located under the left spool.
Two cups are held with a single spring-clip, pressing against a thinned section of the shaft.
The shaft has nicely flattened areas for the set screws to get a proper grip. The thinned section can be seen jutting out of the hole in the spool-base. When assembled, the spring-clip should fit underneath the shaft, pressing the cups into the two holes either side of the spool-base.
The spool holder can then be screwed on, consisting of its base gear, spool-plate and the pillar.
The conical gear on the advance shaft is in engagement with either left or right spool holder when the shaft is pushed in its left or right position. The pillar is stationary and the gear with spool-plate rotates. (The slots in the spool-plate hole engage notches on the special Remington Portable spools. Spool-plate not yet screwed on in picture below.)
At every keypress that actuates the universal bar, the ribbon advance shaft is rotated a little by a push against the advance gearwheel. To prevent it from rotating back again, a pawl locks it in place. When sliding the shaft with all its parts back in position again, this pawl needs to be lifted on top of the advance gear.
As can be seen in the above picture at the arrow, that is what I failed to do. The pawl that can be seen hiding in the dark should have been lying on top of the finely geared advance wheel. (Something we'll know about a next time :)
The shaft can then be fitted with the end control-knobs. These also have the cam-slopes that are actuated by the prongs on the ribbon-fingers that 'measure' the amount of ribbon left on the spool.
In this machine, the parts are oddly of the old pattern - more usually found on older, pre-'25 Portables. This also goes for the spool-locking clips. It seems that the British factory still assembled some machines with the old pattern fittings as late as '27.
With the knobs fitted again and a little tweaking on the position of the gears, the ribbon and spool mechanism is again in place.
(The dastardly pawl has since been lifted to its proper position.)
