(Ci. res-rs The present invention relates to apparatus for electroplating and is a continuation of our similarly entitled application, Serial No. 820,235, filed June 15, 1959, and has for an object a flexible and versatile machine for performing electroplating or other treatments by a compact processing conveyor.
Another object of the invention is to provide an apparatus for conveying work to multiple treatment stations with quickly interchangeable cycles at low maintenance cost.
A further object of the invention resides in providing an apparatus for treatments of articles and materials which involves hydraulic or other operation.
A still further object of the invention resides in providing an apparatus for treatments or" articles and materials in which the width and length of the machine is substantially reduced, the entire machine is made of permissible lighter materials and in which the machine is lower and generally more compact.
Another object of the invention is to provide a novel form of operation of the work carrying members whereby to lift and lower the same out of and into the treatment stations which involves the use of a substantially vertically moving elevator.
A further object of the invention is to provide a mechanism of simplified mechanical form for operation at an accelerated rate of speed and which will accordingly have an increased capacity.

Another object of the invention is to provide an apparatus of the character described in which the downward movement of the elevator raises the work carrying arms while upward motion of the elevator permits a downward motion or" the work carrying arms, the elevator having a certain overtravel to actuate shifters at transfer points.
A further object of the invention is to provide an apparatus having a novel form of horizontal forward movement resulting in shorter tanks, a shorter overall length of the machine and enables a simple sliding mechanism to advance all of the carriers at each operation through a predetermined spacing, for example of the order of twenty-four inches.
A still further object of the invention is to provide an automatic load-unload mechanism coupled to the apparatus for transferring work to and from a supply system.
Another object of the invention is to provide an apparatus of the kind described having a simple form of oscillating device.
A further object of the invention is to provide a completely automatic and automated apparatus in which selective means is employed for changing pattern cycles to increase the flexibility of the machine to any type or cycle pattern desired.
