Details of Lever Counters (Metal & Nylon) – LIMITED PRODUCTION – June 2010

This is a popular and traditional device used by cricket umpires for counting the six balls in the over. Once used, never discarded!

Acumen are delighted to announce that the traditional metal lever counter is now back in production. Limited quantities will be available in occasional batches according to demand. Please email mailto:office[AT]acumenbooks.co.uk?subject=Want_Lever to register your interest. There are no plans for another metal batch at present
BECAUSE we have commissioned a batch of much cheaper but very robust NYLON counters,

both types optionally fitted with wrist strap at no extra charge.











PREVIOUSLY WRITTEN:

The crucial parts of the mechanism
(a) six "fingers" which are mounted on an "axle"
(b) a "spring" which holds the individual fingers in "closed", "halfway" and "open" positions (approx 90 degrees apart)
(c) a reset plate to move all fingers from "closed" position to nearly "halfway" so that they can be easily moved to the "open" position.
(d) a base plate which serves as the "home" position for "closed" fingers but leaves the "open" fingers exposed.
(e) rings and velcro - which we can source elsewhere if necessary.

OPERATION

The umpire starts with the fingers in the "open" position.   As the bowler starts, he raises it to the "halfway" position.   Playing action takes place and the umpire may move - the fingers MUST be stable.   When play ceases, he moves it to the "closed" position unless there was an incident which requires him to return it to the "open" position.

When all six are closed, he calls "Over" and resets all the fingers to the "open" position.

FUTURE DESIGN

The mechanics may be changed in any suitable way but there are two over-riding characteristics that are NOT satisfied by the several wheeled counters available:

(1) There must be TWO positive actions by the umpire to count each ball (he may forget ONE action in the heat of the moment and thereby miscount - much less likely with two actions)

(2) There is a positive outcome at the end of the over - a wheeled counter goes back to zero with no tactile feedback to the umpire and it has been known for him to allow a 12 ball over! 

practical application - 3 balls gone, 1 in progress and2 left=

Closer Look

some idea of length (exact dimension not critical)

some idea of width  (not vital to be exact)

another angle on length

Halfway through reset - the plate lifts the protected elevers to vertical and then they can be pushed to the right whilst the plate returns to the left.
