WHEN putting in window panes or framing pictures, I find the device sketched above a great time saver. The dovetail slot holds the point firmly against the glass and frame while the other end is tapped with a hammer. Another advantage of the holder is that points may be moved to position without slipping.

ON A breezeless day, red danger flags at obstructions or excavations droop down around the staff and are not readily seen. Such warnings can be made more distinct if an old hacksaw blade is riveted diagonally across the flag. This stiffens the flag so it remains unfurled.

Switch Stops Tractor on Tilt

[no value]
[no value]
TRACTORS equipped with this safety switch aren’t likely to tip over on a steep incline or a heavy pull because the motor goes dead when the front wheels rise beyond a safe angle. Tilting the machine more than the predetermined limit causes a steel ball inside the cylindrical chamber to roll backward and actuate a switch that shorts the ignition. When the tractor levels, the motor can be restarted. Warren Manufacturing Co., Inc., Clinton, N. C., produces the switch.
