I'm really sorry, folks ... I'm trying to figure out this patent link/image process, but I just can't get a handle on it. Plus, I just spoke with my dad, and although he left the farm in 1942 to join the CBs, his brother continued working it well into the 1960s. Dad's opinion is that during the late 40s and and early 50s, the children, like in the case of my uncle, decided to make some major changes in the way egg ranches were operated.There was no longer time to write down any more stuff than was necessary, thus the increase in inventions. I came across one invention referred to as a "Poultry Handling System, patent # 3706300, that is really just a huge vacuum that sucks chickens from the barns and deposits them in truck cages for transport. Craziest thing I ever heard of! When I was twenty years old I worked at a large commercial ranch for a while, and by the end of the egg gathering run (by means of a golf cart up and down the isles) I would have no less than 50 flats of eggs to store away in the cooler. I hated it, and can still recall that egg smell.
Anyway, here's a couple more egg counter patents. You can't help but wonder how many variations there were. Which is a good thing, I guess, because it adds hope to the item in question as being one of them. But if it wasn't patented, I think we're in big trouble.
Here's those other two designs I found ...

P.S. Added: I started patent searching under "egg tally" where Bramblefind's image originally came from, and then switched to "egg counter" where I found most of mine, but have hit a dead end on this so called "egg-roll" with both of them. I'm still convinced our item is hiding somewhere among the millions of patents. I'm going back now to do another search on the pool/billiards possibility. That 14/15? number aspect has to be a clue.
