Title: Improvements in or relating to electric induction heating apparatus
Inventor: MILLER HUGH LAURENCE
IPC: H05B6/02
Filed: 1952-11-18
Abstract: 712,087. Induction heating. ENGLISH NUMBERING MACHINES, Ltd. Nov. 18, 1952, No. 29105/52. Class 39 (3) An induction coil 4 is supported within a chamber 2 secured to a support 1, and the chamber includes a cooling fluid nozzle 12, a duct 24 for the supply of compressed air, and an opening 30 facing a work holder 31. The latter is rotatably mounted on a carrier 32 which reciprocates on two guide rods 44 extending between the chamber and a bracket 45. The workpieces are mounted on stems 34 and are heated in turn. Annular seals 37 on the holder close the opening 30 during each heating period. The carrier is reciprocated by a pneumatic motor 48 of the piston and cylinder type fed by a duct 27 and pipes 55, 56, and a manually operated handle 54 controls the supply of air to the opposite ends of the cylinder and hence the movement of the carrier. As the workpiece enters the chamber a finger 64 on a rod 65 operates a switch which controls the energizing of the coil 4 for a predetermined time. At the end of this period a valve 16 is opened to allow quenching medium to flow through the nozzle 12 and from the chamber via an outlet 9. The handle 54 is then operated and during the return movement the carrier strikes a member 26 which opens a valve 25, and compressed air is delivered to the chamber through the duct 24 to remove coolant liquid drops from the coil. Also during this movement a projection 57 on the support engages one of four pins 43 on the holder to rotate it, and a further projection 62 engages a second pin to produce a 90 degrees movement and thereby to position a second workpiece opposite the chamber opening 30. Spring-loaded balls 42 in the carrier which engage notches in the holder retain the holder in position, and additional securing means comprising a guide rail 70 extends between pairs of pins 43.
