Hedoes not have toearn his whip, yetit is ready for useat all times. Hishands are freewhen operatingharvesters, dump-wagons, riding-plows, and this is adecided ad\ constructionof this device isbased on the springand lever upright ironsupport is attachedto the tongue orthill. The upperpart is bent backtoward the driverwith the end ex-. By means ot a lever, this whip can beapplied in any direction with a Stout long rod isattached to thewhip-support at itsjunction with thespring, and this ex-tends backward tothed rivers seat,terminating in ahand-grasp. Thisrod is suspended inits middle portionfrom an angularbracket attached tothe body of thevehicle. This sup-ports the rod andprevents the ballfrom action of theball and spring issuch that the whipmay be manipula-ted in any direction and when released panded into a ring whose diameter is returns to its original position. It is ahorizontal. Mttiiig in the ring is a ball more humane weapon than most whips. Welding Soft Metal to Hard FOR welding copper or aluminum toiron or steel or for welding to anyhard metal, such as iron, nickel, steel orthe like, a comparatively soft metalsuch as copper, zinc, silver or gold, anapparatus has been devised which bringsthe surfaces of the tAvo dissimilar metalsinto contact with each other in a vacuumor partial vacuum
