Cam Gears
This is very interesting but the practical use of it would be in question. A cam and a cam follower would be more like to be used. Consider the wear on the gears as they move what ever the rods are connected to. It is amazing how the gear was made as a casting, I wonder just how they cleaned the casting up. Milling would be a nightmare, that poor machinist!

speaking of different shaped gears,found this one on youtube,good time for Easter,a chicken must lay these gears and the company who made the hay baler dye them red color

here is a similar one

this is also cool

Non circular gears are primarily used for attracting attention creating the mesmerizing effect in most designs. However there are a few real life applications in which the non circular gears play a large part in the mechanical performance of machines, shaft velocities can increased and decreased as the pitch diameter varies without the need for changing the actual gear ratio this action in turn vastly changes the torque output as well.. I seam to remember some ag equipment that was antique when I was a teen that had non circular gearing one in-particular was an animal drawn single row planter which through the arrangement of goofy gears caused the seeds to be placed at odd intervals the spacing reminded me of a Beethoven symphony dit,dit,dit, daaa, Also we had a Bermuda grass spriger that had these so the concept while not at all that common has been around for eons

Just like the video which they were balling hay. It is something we just let die out with technology, but that technology we are able to do with electric and mechanical power. Like the planter that did so many things simultaneously with out dropping a beat. I wonder at times what the world would be like if every did not go through the stages to where we are today. It was not an easy life but there are rewards to everything.
