HOTTER THAN
 THE HINGES OF
 TOWN OF YUMA
Kansas City Invention Pro- duceS Heat That Melts Fire Brick and Other Hard Sub- stances
(Kansas City star)


 4 man with green goggles stood il little workshop. out on East Eff teenth street yesterday afternoon holding in one hand a brass torch of peculiar design. With his free hand te lighted match and applied it to the tip of the torch A yellow flame ihot oat. Then he turned to a steel Tlinder and twisted a stopcOck. ruffled explosion followed and the yellow flame disappeared. Instantly n it's place at the tip of the torch With the uniting of two gases, acct.
 sne and oxygen, there appeared 2 the missing lisx between man anc bulb of fire. dazzling, white and abou: the size of small capsule That small. capsule-lixe flame represented tue hottest fire that ever has been produced on earth. The temperature at the point of the torch was 6,350 degrees Fahrenheit. The hottest fire produced by any other means is made by the electric furnace and it regis ters only 5,264 degrees Fahrenheit.
 The man who was manipulating the torch was Frank Harvey, secretary of the Autogenous Welding Devices com pany. with offices al 602 East Eff teenth street. The torch is known as the oxy-acetylene torch and has been used in the United States about four teen months. It is the invention of a Frenchman. The torch has been in use in Kansas City only since last De cember.
 Mir Harvey applied the fiercely glowing flame to fire brick. The brick was boiling almost the instant the flame was applied and shrank in 10 q mollasses-l!ke lump.
 A piece of Manganese sheet steel. the hardest steel known to science. was placed ia a vase and the flame applied. There was a sputtering show CT of sparks and the flame went through the substance with much the same ease that a knife cuts cheese. while loose end rattled to the floor The hardest steel drill, working stead. fly ten hours a day for thirty days, by actual test, makes no impression on this steel
 piece. of sheet steel an eighth of an inch thick was held between the lips of a pair of pliers while the man with the torch ''pecked" at it with the little burning bulb. Wherever the bulb touched there was a sizzling sound such as is made by red4 hot iron when it comes in contact with water and a hole. clean cut, through the solid sheet steel. appeared.
 Cast iron boiled and bubbled and ran in a rivulet when the man with the green goggles touched 1t with his wonder working wand.
 Burglar Proof" Vaults Are Easy.
 'I can cut figure eights and letter S's through the thickest steel walls of any so-called burglar proof bank vault in Kansas City" Mir. Harvey coOlly announced. "and can do 1t in less time than 1t will take any de. tective on the Kansas City pol'ce force to walk from the city hall to the postofnce."
 This amazing statement simply means that the bank vaults of Kansas City are about as secure as a paper mache box when they come to the test of resisting the deyouring flame of the oxy-acetylene torch A hole large enough to admit a mans body can be burned in absolute silence and in fifteen minutes time in any steel safe ever made, and with an outfit a "cracksman" could carry !n Q couple of travelling bags.
