INVENTIONS AND APPLIANCES OF INTEREST TO AGRICULTURE.

THRESHING MACHINE. The concave in this thresher is placed above and behind the cylinder, so that the cut material drops vertically from the cylinder, and is met by the blast

of air at' right angles. This is claimed to have given in practice better results than are obtained with the usual arrangement of the concave under the cylinder.

PLOUGH ATTACHMENT FOR TRACTORS.

The cross bar of the frame of this attachment is secured to the drawbar cap and the side members are secured under the tractor axle by clips. At the ends of the side members are bearings in which

is journalled a square shaft. On this shaft are flanges to which plough or lister beams are connected. A hand lever is mounted on the shaft to turn it and raise the beams.

ANTI-SIDE-DRAFT PLOUGH HITCH. The object here is to counteract side draft while so arranging the plough that it will cut a furrow in the track of one of the tractor wheels, thus allowing the

tractor to travel on unploughed land. The rear truck, by its weight and the flanges on its wheels, prevents swinging of the offset plough into the line of draft. PLOUGH. The top of the crank axle of the castor wheel here is bent horizontally. When the plough is down, this portion sits in a hood (as noted), secured to the beam, whereby lhe axle is prevented from

swinging and the wheel from castoring. When the plough is raised the top of the crank axle is forced out of the hood and the axle is free to turn in its sleeve.

SELF-DISCHARGING CULTIVATOR.

An elliptical tooth carrier is pivoted in the frame of this cultivator. At each end of the carrier and rigid with it is a disc having diametrically opposed recesses. The frame is locked by dogs controlled

from the handles entering these recesses. To dump the cultivator the dogs are withdrawn, when the upper teeth drop to the ground and are locked when the dogs enter the second recesses. HOG ANTI-ROCKER. This device is made from a single length of wire, as shown. 'Hie pointed

ends are passed down through the snout, and twisted into loops, after which the points are cut off.
