Non-Freezing Mixture.

Protection against possible freezing of wet materials in a cement mixer during cold weather is obtained at low cost by using an oil-burning heater which can be attached to practically any mixing machine. Such a device unquestionably can save money for a contractor by making it safe to operate continuously when the temperature Is low, says Popular Mechanics Magazine. The heater is provided with a 25-gallon tank which is mounted above the mixer and is connected by a pipe with a burner situated at the opening in the side of the mixing drum, compressed air, obtained either from a hand pump or a compressor, is used to vaporize the oil and in this way a flame is forced into the Interior of the drunf, keeping the materials there thoroughly warm.
