A MECHANICAL TREE FELLER

MACHINE operated by steam which fells tres with a minimum waste of time, labor, and material has been successfully used in England. The machine is easily operated by two men, makes i clean cut close to the ground, and has cut trees varying from forty-two to forty-eight inches in diameter about six minutes. The machine is easily moved from tree to tree and has a small, portable boiler which car easily be moved about by one horse and can be kept stoked by the men operating the tree feller. Ev means of an interchangeable frame the machine can be converted, in a few minutes, into a cross-cutting machine so that it cuts logs into desired lengths ir even less time than it takes to fell the tree.

A POWER ATTACHMENT FOR AUTOMOBILES

BY MEANS of an easily adjusted power attach

ment for automobiles the automobile can be mad to run a thresher, cream separator, corn husker, water pump, and perform many other useful functions around the farm. The attachment consists mainly of a drive shaft connecting to the front of the crank shaft through a flexible joint, with a pulley to which is attached the driving belt. A fan in front of the

A little electric heater which, at a cost of less than a cent an hour, if placed near the engine of an automobile in a garage, keeps it warm and eliminates the trouble of starting a cold engine

automobile radiator keeps the engine from over

heating. The pulley runs loose on the shaft, so the belt may be slipped on, then the load engaged by throwing in a clutch which engages the pulley. There is no more wear on the car than there would be in driving along the road at about twenty miles an hour, and the only wear is on the motor itself.

A HANDY SHOE BRUSH

ABOOT brush that contains the paste, brush, and

polisher in one device is a handy innovation for the household or business office. The under side of the brush is divided into two parts. One holds the bristles with which to apply the blacking and rub it on the shoe and the other half holds the device for polishing the shoe. Under the cover is a receptacle for the blacking, which is applied to the shoe by turning a key, conveniently placed in the side of the brush. When the tube of blacking is exhausted the cover slides back and a new tube is inserted.

staples. From two to forty sheets can be bound securely together, without any adjustment of the machine, by pressing the lever down sharply.

AN IMPROVED PIE PLATE

NEW plate for baking pies consists of two pans both perforated, one inside the other. The advantage of having two pans lies in the fact that the crust of a pie thus baked will be of an even thickness throughout and the plates, being perforated, permit of a free circulation of air, so that the botto crust need no longer be soggy and heavy, as is often the case in pies baked in the ordinary manner, but can be baked as light and flaky as the top crust.

AN ACCIDENT PREVENTER

MEANS of protection for workers on presses has recently been devised by the use of an easih adjusted little lattice-work gate which lets down when the operator throws the clutch in to operate a press. Except for a brief instant between the pressing of the treadle and the tripping of the press the gate never interferes with the workmen and, being made like a lattice, the operator sees through it clearly at all times. The moment the work is completed the gate springs back to a folded position out of the way.
