INVENTIONS AND APPLIANCES OF INTEREST TO AGRICULTURE.

C. J. LYNDE, MACDONALD COLLEGE, QUE. PROV., CANADA.

HOG RING

The nose-piece here Is attached by means of two rings. It engages roots aaid other obstructions when the hog roots and thereby pulls and twists the rings in such

a way as to cause pain and stop the rooting.—Robert Roethlisberger, Columbus Grove, Ohio. (U.i>. Patent, 1.372,247.)

MUD CHAIN

This chain increases the traction of the wheels, and is so attached that it cannot move along the tyre. It consists of two side chains with two cross chains, and is

attached by means of straps and covered chains snapped around two spokes.—Geo. H. Slawson, Salem, Missouri. (U.S. Patent, 1,372,373.)

TYRE TOOT.

To remove a tyre with this tool, and operator grips it between the jaws, locks the handles by' means of the dog and ratchet, and juries with the end fulcrum lug bearing against the wheel felly. To replace it, he does what he can by hand,

then inserts the handle end hook inside the wheel rim and pries the tyre into place.—Bjornlie Manufacturing Company, Watertown, South Dakota. (U.S. Patent, 1,372,976.)

CEMENT SILO

The new feature here is the double tongue and groove at the edges of the cement blocks. This makes a strong joint and one that is air-tight and water-tight. The faces of the blocks are made flat for

economy in manufacture, and the angle of the ’ edges is varied according to the diameter of the silo. —Cement Products Company, Worthington, Indiana. (U.S. Patent, 1,372,837.)

TONGUE TRUCK

The special advantages of this truck are that it permits the cultivator, mower, or harvester to rise and fall with inequalities of the ground, without any tendency to lift the working part of the. implement :

also that it permits them to rock sideways without danger of splitting the tongue.— International Harvester Company, Chicago, 111. (U.S. Patent, 1,667,518.)
