This is a another good looking set up probably using some old German agate cutting technology.
I am about certain that the pivot arm simply slides left to right/right to left to pick slab thickness.
The super wide pivot arm swing bearing should guarantee rigid swing motion maintaining parallel cutting motion to saw blade.
That super wide pivot arm swing bearing is used on the saw in the lower photo #2 also.
Notice the vise clamp wheel in #1 on the very end of the swing arm.Down in the saw.
I notice the motors are not mounted on the saw frame but isolated to the floor. Common practice in industry to reduce harmonics/vibration andhigh precision applications requiring no shaking. Could be for convenience too. Also quieter for basement shop.
The swing arm on #1 must weigh 100 pounds, likely more. Basically a super heavy swing arm resilient to chatter/harmonics is my guess. It is counter balanced so it would pivot w/little effort from operator. But does it swing so the rock is being cut on the top of the blade or does the rock contact the bottom of the blade from the reservoir side. Looks like the left side of the swing arm would
hit the blade shaft and the right side would hit the lip on the right side of the reservoir box.
I would guess the rock is swinging from the bottom upwardly and being cut down in the reservoir box. Judging from the higher position of the swing arm shaft. That would explain the need
for pumped cutting oil. As the saw may have to be sitting high if the rock is going to drop below the blade. So the bottom of the blade must not be sitting in reservoir oil.
The swing arm on #2 is mostly hanging from gravity. So the cutting force would be downward also adding to the force of gravity. That might just be a damn good idea. And two German saws with
quite similar designs. Both look home made. Easier to make a swing than worm feed..
This is another view of #1 showing cover installed.
