Introduction
Gathering pallets are essential strike-train components that lift and advance the rack during the striking sequence. Choosing the wrong pallet leads to miscounted strikes, jamming, or a strike train that won’t run at all. This guide explains how to choose the correct gathering pallet for your mechanical clock.
Understanding What Gathering Pallets Do
Lift the rack during striking
The pallet engages the rack teeth and lifts it one step at a time.
Control strike count accuracy
Each lift corresponds to one strike, so pallet geometry must be correct.
Synchronize the strike train
The pallet ensures the rack, snail, and strike wheels stay in proper sequence.
How to Identify the Correct Gathering Pallet
Match the arbor diameter
The pallet must fit the gathering arbor securely without wobble.
Check the pallet arm length
Arm length determines how far the rack is lifted each cycle.
Match the rack tooth spacing
Incorrect spacing causes skipping, jamming, or double-lifting.
Matching Gathering Pallets to the Movement
Identify the movement manufacturer
Hermle, Urgos, and Kieninger use specific pallet shapes and arbor sizes.
Match the rack and snail system
The pallet must lift the rack the correct amount for each hour.
Check the strike train timing
Incorrect pallet geometry disrupts the entire strike sequence.
Common Gathering Pallet Materials
Hardened steel pallets
Most durable and ideal for long-term strike accuracy.
Brass pallets
Common in antique clocks and lighter strike trains.
Alloy pallets
Used in some modern movements for reduced friction.
Common Mistakes When Choosing Gathering Pallets
Incorrect arbor bore
Too loose causes timing drift; too tight causes binding.
Wrong pallet arm length
Leads to miscounted strikes or rack jamming.
Incompatible rack tooth spacing
Even slight mismatches cause skipping or double-lifting.

FAQs
How do I know which gathering pallet my clock needs?
Match the arbor bore, pallet arm length, and rack tooth spacing to the original movement.
Can I adjust a gathering pallet?
Minor adjustments are possible, but bending too far weakens the pallet or alters timing.
Why does my clock strike the wrong number?
Likely due to incorrect pallet geometry or mismatched rack spacing.
Do gathering pallets from different brands interchange?
Only if the arbor size, arm length, and rack compatibility match exactly.
Why does the rack jam during striking?
The pallet may be lifting too far or engaging the rack at the wrong angle.
