This is a reference intended for those who enjoy the hobby of watch & clock repair.

The pin-pallet escapement was invented by Achille Brocot (1817-1878), a very able French clockmaker. Variations of the Brocot escapement are to be found in the clocks of many nations.

"Pin-pallet" refers to the semicircular "D" shaped pallets used to convert the rotary motion of the escape wheel into oscillating pendulum or balance wheel motion.

Those clocks that are constructed with the escape wheel, bridge, and pallets in plain view in front of the dial are commonly known as "outside" or "visible" escapement clocks.

The pin-pallet escapement requires very precise adjustment of its component parts to function properly. This guide was written to help point out the several important details that need to be looked after when repairing or adjusting this type of escapement.

It is suggested that the entire guide be reviewed before making any adjustment because it is easy to mistake one symptom for another. Worn pallet anchor and escape wheel pivot holes may be incorrectly diagnosed as a center distance problem, for example.

Sensational Toy By Nylabone Keeps Your Best Freinds Teeth Snow White!
Flavor Name: Bacon, Size: X-Large
Our Bull dogs LOVE these bones. Long time Nylabone fans they've been making quality dog toys here in the United States for over fifty years. The nubs on the end of the bone age great for cleaning teeth and massaging bones. The center is softer but still holds up to even the toughest aggressive chewers. For whatever reason this isn't a "favorite" toy in the sense that they drag it around a few hours a day but they do play with it and we replace them when the ends start to shred - which should be done with all nylabone chew toys. The price on Amazon is virtually half the cost of the big box pet stores so it's affordable - not to mention fun to replace their toys and try new ones often. Plus with a Prime membership almost every item we buy ships with Free two day shipping - making the deals even that much sweeter.

You've got to be kidding. Really !!!
Flavor Name: Bacon, Size: X-Large
I've used these for over fifteen years They are great. But, mine only lasted two days this time. Lucy the Labrador, left it in the driveway one afternoon. The next morning a huge garbage truck ran over it, making dust out of it. Normally, Lucy cant go any ware without it, so leaving it outside was her fault. And mine, for not checking. Yes, I ordered another one right away. Otherwise, she would have drove me crazy. These are great, and they last a long time, even with the most aggressive chewers. Lucy, passed away on June 16, at age 13, but you can bet I still have her favorite bone. The more a dog chews on these, the better they brush the dogs teeth. A+ product, just like their other items.

Large, Heavy, DURABLE!
Flavor Name: Bacon, Size: Medium
This bone is probably too big and heavy for my medium size cocker spaniel. But I bought it anyway, because he was able to demolish the Nylabones that were labeled "for medium dogs". He can still pick this one up and carry it around, but he cannot fit an entire end into his mouth. Still, he loves it--he's greedy and relishes the fact that he has such a big bone all for himself. He even sleeps with it! I like it because of the fact that it doesn't completely fit into his mouth. Due to this, the bone has lasted much longer than all the other Nylabones I bought him in the past. And because he can't shred this one, I don't find sharp bit of Nylabone fragments everywhere and it doesn't make his gums bleed either. I happy I found this and will continue buying oversized Nylabone toys for my dog!

Durable
Flavor Name: Bacon, Size: X-Large
My dog loves these, we used to get him one size smaller. But after a month or so he would have the end knuckle chewed open trying to get at the inside. This one here he chews on it all day and hasn't put a dent in it. Great dog bone.

The Dogs Here LOVE This Toy!
Size: Large/Giant (1 Count)
This is a great addition to the toy box! The dogs I have are heavy chewers and it stands up to their teething needs. It's a great shape for them to hold and I'm sure it's helping to keep their teeth free of tarter. It gets a lot of use here!
