A Wind-Deflecting Lookout Mask for Engineers
A STEEL mask for railroad engi- neers which secures for them a clear vision ahead, that cannot be obscured by the snow, rain or sleet, is being tried out on engines of the Canadian Pacific Railroad, mask, which is attached to the window- frame of the cab, contains no glass, its principle being based on the deflection of wind currents 1j\- flanges.

��An Adjustable Steering Device for the Farmers Tractor
NOW comes the ?ell-sieered light farm- tractor, so built that the operator can gi\e more attention to his plows and tiiat an\- irregularities in the furrows are com- pensated for. Two disks, mounted on a rod attached to the axle of the front wheels, are set so that their rims or edges are closer together at the front than at the rear. The outer disk is larger and is -'-5-- set lower than the inner one, ', ', so that, when placed in a
--, furrow, it pushes the inner
/ one against the land-side of
the furrow. The tractor- wheels are pre\ented from swer\ing by the pressure of the inner disk against the land-side of the furrow. The disks are mounted on a rod supi^orted by chains, pulleys and a lever, which raise them from the ground for turning corners or for mo^•ing the tractor from the field.
