## Abstract

A shearing cradle to support a sheep in a reclined position on rollers. Shearing device situated between a pair of rollers, so that as the rollers rotate, the sheep is shorn by the shearing device.

## Claims

### Claim 1

Apparatus for shearing sheep, said apparatus comprising a frame supporting a plurality of propelled parallel rollers extending longitudinally of the frame to support a sheep in a reclining position, an endless belt cutter positioned between an adjacent pair of said rollers, said rollers being positioned to have central and outermost rollers with the central rollers lower than the outermost rollers to allow the sheep to lie on the rollers, said cutter means being characterized by said endless belt cutter having a course extending axially of said rollers intermediate said central rollers, and means to drive the rollers to move the sheep through an arc to present the unshorn wool to the endless belt cutter.

### Claim 2 (depends on 1)

Apparatus for shearing sheep as defined in claim 1, wherein said cutter means is characterized by said belt cutter cooperating with wire like fingers of a comb and, all of said rollers have surface portions lying in an arc and forming a support for the sheep, said endless belt cutter course also lying in said last-named arc.

### Claim 3 (depends on 2)

Apparatus for shearing sheep as defined in claim 2, wherein said fingers overlie the endless belt cutter and some of the fingers are shearing fingers that protrude past the cutting edge to penetrate the wool before it is cut and the other fingers extend beyond the cutting edge to maintain the skin spaced from the cutting edge, and means positioned below said course of said endless belt cutter to aid in operatively positioning the same.

### Claim 4 (depends on 1)

Apparatus for shearing sheep as defined in claim 1 characterized in that said endless belt cutter has a serrated cutting edge to engage and cut the wool.

### Claim 5 (depends on 1)

Apparatus for shearing sheep as defined in claim 1 wherein the fingers overlie the endless belt cutter and some of the fingers protrude past the cutting edge to penetrate the wool before it is cut, and the other fingers maintain the skin space on the cutting edge.

### Claim 6 (depends on 1)

Apparatus for shearing sheep as defined in claim 1 characterized in that at least one of the rollers engaging the shorn skin of the sheep is provided with frictional material to grip the skin, assist in turning the sheep and maintain the skin taut over the cutter means.
