Abstract

A brake lock system for a pumpjack brake apparatus comprises a latch handle lever pivotally mounted at a location on a pumpjack, a countershaft rotatably mounted on the pumpjack, latch handle linkage, and control linkage that transitions movement and force of the latch handle lever to a latch arm with a latch dog for pivoting the latch arm to insert the latch dog in a notch in the pumpjack brake apparatus. The latch handle, latch handle linkage, control linkage, and latch arm have dimensions that provide a mechanical advantage of the latch handle lever over the latch arm.
