N. J.,-a corporation of New Jersey Application January 21, 1938, serial No; 186,190

f9 C m (01. 214-11) My invention relates to electroprocessing machines. 7'

It is an object of this invention to provide pneumatic or hydraulic elevating and lowering means for the carrier arms, and pneumatic or hydraulic shifter means for simultaneously shifting through the elevator, both the carrier arms in engagement with the elevator and those not engaged with the elevator, that is by shifting the carried chains through the elevator.

It is an object of this invention to provide a vertically moving elevator that also reciprocates, and by its reciprocation, advances the transverse horizontal conveyor means appro- "15 priate steps so that the elevator is utilized as a common means for raising and lowering the carrier arms and for also shifting them bodily as a unit, horizontally.

It is an object to provide an elevator that 9,0 selectively elevates certain carrier arms and lowers others, while it is also capable of moving all of the carrier arms a predetermined hori zontal distance.

It is an object to provide sucha hydraulic gand pneumatic shifting means which eliminates the necessity for any motor drives, or other mechanical means of imparting horizontal or vertical movement to the several parts of the electroprocessing machine.

30 It is a further object of the invention to proelectroprocessing machine of this invention with a portion of the tanks in section, and a portion of the chain guide rail'and vertical carrier guides broken away;

Figure 11 is a section on the line Il-ll of 1 Figure 10, looking in the direction of the arrows;

Referring to the drawings in detail, I and 2 indicate vertical standards of a framework.

3 designates horizontal floor pieces upon which 80 rest the tanks 4 and 5.' The horizontally disposedchains l9 and 20, which are mounted uponthe sprockets I1 and I8, are connected together by the vertically disposed pairs of guide rods 25. These chains v travel in upper guiderails 2| and 22, and in lower guide rails 30 and 3t.

.The transverse guide rails for the carriers 25 are provided with heads 24 at the top, and 20 at the bottom. On these rodsare mounted the blocks 26, which are provided with the rollers 21 and 28. These blocks 26 carry the side arms 3|.- These side arms 31 carry the work carriers 38, that are connected by cables 39 to spring pressed contact shoe 38, which is supported by the bracket 34.

- The block 26 is provided on its back with a projecting lug 20i that has a cam surface 202 on its under side. A pivoted weighted latch hook 203 is adapted to have its nose 204 project beneath this lug 20l. When it does so, this nose 1 204 projects through the opening 205 in the The latch I tance. Then the elevators lower the arms they have picked up. The elevator shifter is returned to its initial position, and is ready to pick up a new set of arms.

When this occurs, the shifters 206, of which there is a pair, have been shifting on the ball bearing 2 in the --elevator frame 2l2 that is guided vertically by the rollers 2l3 on the guide rails 214 on the vertical members I and 2. This elevator frame 2I2 carries a transverse shaft 2|5 with pinions 2l4a engaging with racks 2l5a carried by the respective elevator shifters 206, so that when one elevator is movedin one direction to move the carrier arms in one direction, the other elevator shifter will be moving in the other direction an equal amount with the oppositecarrier arms.

This shifting is brought about by the pneumatic or hydraulic cylinder 2l6, which is supplied with fluid pressure through the pipes 2H and Mia. The cylinder is mounted upon the elevator frame 2l2. Its piston rod 2|8 is connected to the bracket Hi! to one of the shifters 206.

The elevating means for the elevator consists of piston rods 220 operated by pistons 22l in the lifting cylinders 222, which are supplied with fluid pressure 223 from a suitable source. Thus the elevators are lifted for giving vertical movement to the carrier arms 31 on the guide rods 25. When the elevator is in its uppermost position, it is actuated by the cylinder 2i6 and piston rod2l8 to move it tow the right, which results in the angle irons 2l0 pushing the carriers and the chains I9 and 20 a given distance horizontally.-

Then the elevator is lowered and the carrier arms are disposed in their lower position having been advanced one step. Thereupon the shifters on the elevator 206 are returned to their initial positions, ready for another latch engagement with another set of carrier arms to lift them and transport them over the adjacent partitions between the tanks 4 and 5.

Thus this machine is characterized by the fact that it has (a) means for elevating the carrier arms selectively as only those arms opposite the latches are elevated; (b) it has means on the elevator for moving the selected arms when in an elevated position, and all the rest of the arms in a lower position, equally a given horizontal distance (0) it has means for lowering the elevator and the selected arms and means for returning the elevator to its new left handposition for another cycle of operations.

Referring to Figure 14, this illustrates diagrammatically one form of control for the raising, lowering and lateral shifting of the elevator. The pressure tank 225, which may alternatively be an accumulator, supplies fluid pres sure to the lifting cylinders 222 through pipes 223 as heretofore described. Fluid pressure is supplied to the tank 225 through the pipe 226. Fluid pressure is also supplied from the tank 225 through the pipe 221, valve 228, rotor 229 and pipes 2|! and 2l'la, to the lateral shifting cylinder 2l6. Connected to the rotor 229 is the lever 230 which is connected to the lever 23| by the link 232. This lever system is controlled by the raising and lowering of .the elevator 205 so that the lateral shifting movement will be timed are numerous different ways by which the movement of hydraulically liftingband lowering and hydraulically shifting may be accomplished. Either air or fluid may be utilized.

It will be understood that I desire to comprehend withii! my invention such modifications as may be necessary to adapt it to varying conditions and uses.
