Well we all debate on how we should look after our leaf springs. This it seems is what we need. I never seen one of these before.

That looks quite brutal.

I don't think it was ever in the Rolls Royce/Bentley tool kit.

These vehicles had a built-in chassis oiler - an extra pedal that you were required to press every so often to deliver a drop of oil somewhere ... maybe chassis bushes - I never investigated it properly.

I used to have one of those. Great on good compliant springs, but was less keen to come out than go back in. I recall once giving it a clout sideways to try and free it in frustration. In the process I managed to hit myself with the mallet and the tool flew out and shattered my tea mug. I haven't seen it since, so its probably festering in some lost corner of Zimbabwe.

If you look at old 1930/40s adverts it was a common accessory for greasing springs. I have seen one like a G clamp so that you grips the other side to wind it in to spread the leaves

I have one of those and use it on all the springs once a year.
One of the reasons for neglect of spring lubrication is the difficulty experienced' in separating the leaves so as to be able to insert grease or oil. To overcome this obstacle Herbert Terry and Sons, Ltd., of Redditch markets a leaf-spring greaser of the type shown in the accompanying illustration. The fixed wedgeshaped blade is passed inside the spring whilst the movable blade is outside it. Rotation of the screwed bar forces the spring leaves apart and the grease-gun is then applied to the nipple fitted to the end of the bar ; lubricant exude, through an aperture in the movable blade.
In operation, the clip around the spring leaves has to be removed before applying the greaser. The price for the device is 8s. 6d., and it is supplied with a nipple suitable for use with either an Enots or Tecalemit gun.”

That looks a more friendly device, screwing in between the leaves seems less violent than bashing a wedge in with a hammer.

And, of course in these times we have Aerosol cans of motorcycle chain grease, a substance that is very runny and free flowing to get to all places in between the spring leaves - then after 10 minutes or so it thickens up in the air and becomes very sticky (designed not to be flung off motorcycle chains).

Looks like it could double as a nut splitter
