Hi Collin
Just been looking at the Gamage’s roller, OK Gamage’s sold this roller with their name on it, like a lot of Ironmongers did, Allan is quite right T Greens of Leeds did make many garden rollers under their own name and others, the termination for this type of implement selling is and was called catalogue machines.
However in this case, Green’s did not make rollers for Gamage. Infact there was a society which evolved within all the different manufacturers of garden rollers.
It was Qualcast of Derby who made the Gamage roller, now with the history laid to one side, let me try and sort your problem out!
The reason why your roller is ceased, at some point it has been left outside in the elements, where water has got into the journals where the axle is, now what you cannot see from looking at it at the moment is what is inside. Your roller has two castings that you can see, the idea is as you turn a corner, they should independently rotate different ways on that axle, where they will be ceased is in the middle, as well as slightly on each end.
What you do. First remove the handle from the two bolts on either side. Then you need to make a cradle on the ground of say two concrete blocks of at least 6 inches high, place a timber plank on top (to cushion) then place the roller on its side on top so the axle is clear of the ground.
Now the axle on the top can be worked on, there are many ways to do this, but to help free the journal pour diesel around the axle and leave for a couple of days, What I have done in the past is to heat up the side axle bracket with oxygen and propane, there is a bolt which fixes it to the axle which needs removing, with heat that then can be removed, which will open up your way to the journal, if you need to add pressure or shock by using a hammer only do it by hitting the axle and only then with a piece of wood between your hammer and the axle. do not hit the casting! A couple of days should free it, then once you get the axle out keep it well greased on replacing it. – best of luck.
