Definitions

  • the present invention relates to an induction oven having a series of work-pieces in tandem within the working space of the induction coil, which oven is preferably designed for the vertical passage of work-pieces, and the object of the invention is to overcome the problems encountered in feeding and discharging work-pieces of varying lengths.
  • An inductance coil it placed in vertical position has guide rods 2 arranged in the working space and along which a series of stacked work pieces 3 can be moved.
  • a sliding piece 4 serves for imparting the forward movement of the stack. If the working space of the coil 1 is filled completely, the slide 4 moves upward until the front surface of a work-piece 6 to be removed brings a carrier 7 into engagement with a contact 7', whereupon the forward displacement of the slide 4 ceases.
  • the displacement in the forward direction is controlled by movable abutment 7 and the displacement in the backward direction is controlled by the member 11 and the contact 13, is made adjustable as indicated by the adjacent arrow, the forward and rearward displacement of the stacked work-pieces is substantially independent of variations which may influence the total length of stacked work-pieces.
  • the object of the movability of contact 13 is to permit variation in the displacement of the stacked workpieces in the backward direction to permit the use of the oven for work-pieces of many different lengths.
  • clamping plates 14 approach each other and grip the lowest work-piece between them, whereupon the slide 4 moves down further, so as to leave a space within which additional work-pieces are supplied.
  • the combination with a vertically positioned oven having an exit at one end and :an entrance at the other end and apparatus for feeding and extracting one workpiece at a time from a column of work-pieces of varying length within said oven comprising, a slide member for raising and lowering said column in a vertical direction, means for moving said slide member, column elevation determining means positioned relative to the exit end of said oven for engaging a work-piece externally of said exit end and terminating movement of said slide member, means operatively connecting said elevation determining means and said means for moving said slide member, a follower member frictionally coupled with said slide member, stop means for engaging said follower member in the raising direction of movement of said slide member whereby said slide moving relative to said follower when said follower is engaged with said stop means, clamping means positioned relative to the entrance end of said oven for engaging a work-piece externally of said other end upon lowering movement of said slide member and adjustable means in the path of lowering movement of said follower member, said adjustable means being operatively associated with said clamping means for
  • clamping means comprises a pair of opposed plates and means for moving each said plate toward and apart from one another.
