Filed: 1946-08-27
Abstract: 616,084. Metal spraying. BALLARD, "W. E. Aug. 27, 1946, No. 25545. [Class 69 (iii)] In a metal spraying pistol in which melting of the metal is caused by electric arcing at 13 between two metal rods, e.g. 10, the melted metal being projected by a gas, e.g. air, the speed of approach of the wires is conditioned by the electrical conditions at the point of approach. The wires 10 are fed through tube 12 towards the arcing point 13 by and between rollers 21 and 11. If the wires 10 fuse together at 13 causing a short circuit, a magnetic clutch 31, fed from the same transformer source, ceases to hold down the lever arm 18, whereby a compression spring 29 pivots the frame 15 about 19, thus bringing into feeding contact with the wires, the other feed rollers 22, 11 to cause a reverse feed of the wires 10 to break their fusion and restart the arc. This causes sufficient current to be re-supplied to the clutch 31 to attract it to reset or repivot the frame 15 to disengage feed rollers 22 with 11 and re-engage feed rollers 21 with the other roll 11, thus re-establishing forward feed of the wires for normal spraying. The magnetic clutch comprises a high resistance shunt coil 32. The feed rollers 21, 22 are geared together, the roller 21 being driven continuously by a gear 27 from the shaft 28 of an electric motor or an air turbine.
