In
Fig. 4948, the central blade is pivoted to one of the main blades, and its slotted shank is pivoted to an oscillating lever, which has its fulcrum on a stud from the side bar, and has a slotted connection to a pivot on the other main blade.

Three-bladed shears. |
In
Fig. 4949, the teeth of the cutters are doubleedged.
The cutter-plates are connected by a screw which is secured to one plate and traverses a slot in the other plate.
The spring has one or more coils.

Multiple-bladed shears. |
Fig. 4950 is a sheep-shears with a six-fingered comb and a revolving bladed disk.
It is designed to be used in a machine such as
Fig. 4942. The shearing-comb is suspended from a crane by means of a flexible shaft, rotated by a hand wheel and belt, and descending in line with the axis of the mainwheel of the shearing-comb, to which it imparts motion and from which the cutters of the comb are actuated.

Machine sheep-shears. |
Fig. 4951 is a portable sheep-shearing instrument operated by air under pressure, the engine to operate the cutters being inclosed within the handle, and the compressed air being conducted thereto by a flexible pipe.
The reciprocating cutter is oscillated by a lever.
