By the use of the V-shaped head C, which oscillates on the partition D, two forcing-chambers, K L, are constructed, the alternate action of which produces a uniforrndisoharge'of air into the common receiving-chamber M.

Two or more discharge-pipes, ,N O, connect with the receiver, the ventage of which can be governed at will by means of valves P g.

The bellows are connected to and operated by a revolving shaft, E, through rod S, lever T, rod U, and crank The shaft is provided with an ordinary flywheel, and can be operated at will by either pulleyW, lever T, treadle Y, or handle X.
