Yep. We used them a lot back in the day. Most houses and outbuildings in Wallowa county were built on "foundations" of a bunch of piles of rocks. We'd jack the building up (use hydraulic jacks for the actual lifting), level it and use those house jacks as stands while we built new foundations--usually filled cinder block. I must have worked on a dozen of those. The screw jacks were much faster and easier to use than cribbing.
