Clamp Bars - The bars that runs between the uprights that the quadrants sit on?


I use the term clamp bars because that's what they do. They nip it all together. Some quadrants will sit on these bars. Others, namely those that sit above the uprights, the bar has to thread through. A construction drawing may well have another name for these bars.

Have your levers got their shoes on, I presume so but your picture stops short of the lever bottoms. This is the casting that the lever is bolted into and pivots on the spindle rods that sit between the upright projections of the sole plate. I am going to the railway tomorrow so I'll try and get some suitable pics to help you.

Hi Martin,

I assume that we are talking about these parts? They're not attached but we have all of the bits to put them back on.

There's a luxury. The three Steven's frames i've taken out have the levers in one piece with a boss each side of the pivot. No sliding the lever out through the quadrant.

That would be because you have been looking at English Stevens frames which went out of production at a very early date. The Scottish type (which were to different dimensions) were perpetuated through to the 1970s so naturally have some features not found on the English ones.
