584,650. Cutting by fusion. CURRAN & CO., Ltd., E., and JOYNES, F. Jan. 17, 1945, No. 1372. [Class 83 (iv)] A flame cutting apparatus particularly for cutting armour plating on non-planar surfaces of vehicles &c., comprises a bar secured at one end to the surface to be cut and carrying a rotatably mounted slidable collar, which supports a cutting nozzle holder movable about the bar axis as a centre, the position of the collar along the bar being adjustable in relation to the surface to be cut. The bar 1 which may pass through a hole in a non-planar surface or may be secured in a socket welded thereto, may be provided with a flange 4 and may be secured to the plate 2 to be cut by a cotter passing through a slot 3 or by a three-pronged clamp 17 having a spherical bearing surface engaging a similar surface on a nut 18 screwed on the bar. A collar 5 which is slidably and rotatably mounted on the bar by a ball-bearing 6 has the inner race secured to a sleeve 7 pressed upwards by a spring 10. The upper part of the bar is screw-threaded to engage a nut 8 provided with an adjusting handle 9 or the collar may be screw-threaded to engage a thread on the bar which may be rotated to effect the adjustment. To a lug 11 on the collar 5 is bolted an angularly adjustable arm 12 which is bolted at its lower end to a lug 13 on the outer ring 14 of the cutter nozzle holder assembly which supports through a ballbearing 15 a holder 16 to receive a hand torch 20.
