Abstract
167,014. Chapman, W. H. May 7, 1920. Heating and drying apparatus.-Printed paper is dried and the static electricity thereon is neutralized by passing the paper in the vicinity of gas flames charged with alternating electricty of high voltage. The controls of the press, gas supply, end electricity supply may be operated simultaneously. A sheet 2 passes over a perforated gas pipe 3 supported in insulating-bushes 8 by clamps 7 fixed to brackets 5 of the carrier delivery arm of a printing-press. The pipe 3 is connected through a mixing-chamber 10 to a pipe 12 supplied through a valve 13. One terminal of a sparking-plug 15 screwed into a sleeve 14 surrounding one end of the pipe 3 is connected to one end of the secondary coil 17 of a transformer, the other end being earthed. The primary coil 19 of the transformer is supplied from a source of alternating current, a switch 21 controlling the circuit. The press may be driven by a motor controlled by a switch 23. Rods 25, 27 may connect the three controlling-levers whereby the press is stopped, the gas shut off, and the primary curcuit 19 broken simultaneously. The sparking-plug serves also to relight the gas. The paper may pass beneath the pipe 3, the flames then being directed downwards, and the pipe 3 may itself be charged in place of using the sparking-device.
