IMPROVED GANG PLOW.

Ezra Peak, Montana, Kan.--This invention is so constructed that it may

be easily raised from and lowered to the ground, and adjusted to work

at any desired depth in the ground. It is claimed to be of lighter

draft than plows constructed in the usual way, also to be simple in

construction and inexpensive in manufacture. The wheels, the faces of

which are notched to give them a slight up-and-down movement as they

are drawn forward, slightly jar the plows, and thus cause them to be

easier drawn than when smooth wheels are used. The shaft can be

provided with a ratchet wheel and pawl to hold it in any position into

which it may be turned; and to it is attached a rope or chain, the

other end of which, is attached to the forward end of the frame, so

that by turning the shaft the plows may be raised from, lowered to,

and adjusted to work at any desired depth in the ground.
