Marc,
I, um, lifted that from the Ebony website, I was too lazy to get my digital camera out!
Benjamin,
Those little wheels are the front and back standard focusing knobs. Ebony designed a very unique design variation on the standard folding field camera with this non-folding design that makes quick work of setting the camera up. There is a good article on the design at:

Another unique feature to this wooden field camera is asymmetrical swings and tilts on the back standard. You can learn about it here:

This feature has been used on monorail designs for decades, first developed by SINAR, the Swiss camera manufacturer.
For those of you fully entrenched in the digital age, this camera may seem daunting to figure out, but I know that John Hall would instantly find this camera easy to use. So, Rickenbackers and view cameras are a must for all of us to learn about!
