Claims7
A shearing device including means to support an immobilized sheep, a linkage system including a frame pivoted about an axis transverse to the sheep, a beam pivoted to the frame parallel to the transverse axis, and a pair of caliper arms pivoted to the beam by a connection allowing pivoting about two axes at right angles to each other and generally at right angles to the said axis of said beam, cutter means on each caliper, and means to control the movement of the linkage system whereby the cutter means pass over the body to shear the wool therefrom.
A sheep shearing device including means to support an immobilized sheep, cutter means for fleecing the sheep, support means supporting the cutter means for universal movement in and out, fore and aft, up and down and at various co-ordinates in between relative to the body of the sheep so the cutter means can sweep over any part of the fleece on the sheep body, control means to control universal movement of the support means, said control means including programmed means based on an average sheep size, and sensing means adjacent the cutter means to provide a signal to the control means to modify the angular position of the support means relative to said program so that the cutter means follows the contour of each individual sheep to suit the size of the sheep being shorn to the extent it departs from the average sheep size.
