tumbler???? and the difference between tumbler and roller?

[welder]

what is it and why do they call it a tumbler welder

[Trees Gray]

Well, Dexter who is the authority on Tumblers/Rollers, can better answer the question, hopefully he will be along.

But they are a type of pigeon breed, quite lovely, that actually will perform in the air. They tumble/roll in the air when trained and housed correctly.

It's a breed of pigeon and they tumble or roll in the air while flying. Go to YouTube and do a search on Roller pigeons.

Its one of those things, as far as I know, that a roller is a tumbler but a tumbler in not a roller. Just like a racer is a homer but a homer isn't necessarily a racer.

Aloha Welder,

The main difference between tumblers and rollers is that most tumblers will perform "flips" while flying. What I mean by that is that they will somersault backwards while flying but it would be single somersaults and not a continuous flow of somersaults. They can do 4-5 of these flips in a row but there are pauses between each somersault.
Here is a quote from the 1800's describing the performance of a Birmingham roller.
"A true flying performing roller turns over backwards with inconceivable rapidity through a considerable distance like a spinning ball." Also, "Rollers are those which at every exhibition of their rolling powers pass through an unaccountable number of backward evolutions or somersaults, in such quick succession as to appear like a falling ball."
The performing rollers will somersault and "drop" from anywhere between 10 feet to 100 feet. A few years ago a couple fanciers took some high speed video equipment and studied the rollers and came to the conclusion that the fastest rollers would somersault at the fastest, about 13 revolutions per second.

Typically when people say roller, it refers to Birmingham rollers, who do backflips in the air.
And when people say tumbler, they either don't roll like West of England Tumblers, or roll on the ground like Parlor tumblers/rollers. I'm pretty sure there are tumblers who roll in the air too 'Tumbler' and 'roller' often gets switched around so saying one just does 'this' and the other just does 'that', may not always be true.

The tumblers I has years ago would only do one back flip at a time. They would fly for a while and then do a single flip. Where a roller does not do a single flip but rolles twards the ground. I have seen them not come out of the roll in time and hit the ground!
