ABSTRACT:
A shearing device for shearing sheep. The shears include a hollow handpiece, comb, fork, cutter, and tensioning arm. The comb has a planar face and is rigidly attached to the front of the handpiece. The fork is pivotally mounted within the handpiece with the cutter attached to one of its ends and supported in sliding engagement with the comb's planar face. An arrangement for adjusting the pressure with which the cutter engages the comb includes the tensioning arm which is pivotally mounted with a first end portion abutting the fork and a second end portion extending along a fixed, pivotal axis that is colinear with the pivotal axis of the fork. The adjusting device applies a force to the second end portion of the tensioning arm symmetrically about and axially along the fixed, pivotal axis and the tensioning arm serves to transfer this force to the fork symmetrically about and axially along another axis that is perpendicular to the planar face of the comb. The arrangement of the tensioning arm and fork and the manner in which the force of the adjusting device is transferred to the fork and cutter results in a cool and even running shearing device in which the cutter applies an even pressure to the comb along its entire path of travel across the comb. Several safety features are also present including a square gripping handle for better control and alignment and an arrangement whereby the tensioning arm cannot be separated from the fork during normal operation of the shears.
