Plain Bob Calls

We have seen that in Plain Hunt Doubles only 10 changes can be obtained using the first two rules; and in Plain Bob Doubles only 40 changes can be obtained from the three rules. Therefore we need one further rule to allow us to reach the 120 changes possible on five bells. This extra rule is in the form of a command that is spoken by the conductor, this is known as a "call", and in Plain Bob Doubles the call that is usually used is the "Bob".

The New Rule

So in order to extend the number of possible changes from 40, the conductor will call "Bob" just before the 40th change. When a Bob is called a forth rule (in addition to the three rules discussed in the Plain Hunt and Plain Bob description) is applied. This new rule is that the first and forth bells stay in the same position and the other bells swap. The Bob is always called at the lead end and is applied instead of the third rule where seconds is made. After applying this forth rule, we then continue applying the first two rules as before.

3 1 5 2 4 38th change: Apply rule #1
1 2 4 3 5 39th change: Apply rule #2 <- Conductor shouts "Bob!"

1 4 2 3 5 40th change: Apply rule #4
4 1 3 2 5 41st change: Apply rule #1
4 3 1 5 2 42nd change: Apply rule #2

This has the following effect on the line of each bell:

Bob Doubles Work

In the above example:

  • the 2nd runs in and becomes 2nd place bell (again);
  • the 3rd runs out and becomes 3rd place bell (again);
  • the 4th is unaffected by the Bob and makes long fifths (as it would have done), becoming 5th place bell;
  • the 5th makes the Bob and becomes 4th place bell.

Circle of Work

To explain this a different way: the effect of this Bob will be that three of the bells will jump to a different point on the circle of work:

Bob Doubles Work

The Full Extent

Continuing to apply the first three rules after the Bob will then bring us another 40 changes, at which point the conductor will call another Bob to give further 40 changes, then a final Bob will bring the bells back into rounds after exactly 120 different changes and no repetitions.

More Terminology

The introduction of calls brings some additional terminology:

Run In

Describes the movement of the bell that starts off in 2nds place and would have dodged 3-4 down at the lead end, but is said to "run in" if a Bob is called. The result is that it becomes 2nds place bell again and repeats the lead it has just done.

Run Out

Describes the movement of the bell that starts off in 3rds place and would have made seconds at the lead end, but is said to "run out" if a Bob is called. The result is that it becomes 3rds place bell again and repeats the lead it has just done.

Make the Bob

Describes the movement of the bell that starts off in 5th place and would have dodged 3-4 up at the lead end, but is said to "make the bob" if a Bob is called. The result is that it becomes 4ths place bell.

Unaffected

Describes bells that are not affected by the call. In Bob Doubles this is the bell that starts off in 4th place and it continues to make long fifths as normal.

Plain Course

A plain course is when a method is rung with no calls being made. So only the first three rules in Bob Doubles will be applied.

Touch

A touch is when a method is rung with calls being made.

Different Touches

In the touch described above, the conductor calls a Bob each time the method is about to come back to rounds. However Bobs can be called at any lead end and, providing they are called at the correct lead ends, the full 120 changes will still be made.
