THE most recent addition to the range of cutting machines produced by the British Oxygen Co., Ltd., Bridgewater House, Cleveland Row, St. James's, London, S.W.1, is known as the Bantam and weighs only 221lb. complete with cutter. Mild steel up to a thickness of 2 in. can be cut, and when used in conjunction with the radius bar, circles of between 3 in. and 45 in. diameter are within the scope of the machine. Cuts can be made at any angle up to 45 degrees, whilst provision is made for adjustment for lateral movement and height. The cutter uses the Cutogen one-piece nozzle, which gives clean machine-finished cuts on slow curves when free cutting. For this purpose the machine is steered by a handle at the rear and it can then he made to follow curves marked upon the surface of the plate. The castor trailing wheel can be locked for running on a track and disengaged for circle and profile cutting. On straight-line cutting using a 1132-in. nozzle, k-in. p:ate can be cut at the rate of 130 ft. an hour, whilst with a nozzle, 2-in, plate can be cut at the rate of 40 ft. an hour.
