Application filed July 22, 19,25. Serial No. 45,289.

Our invention relates to machines used for pickling of wire or rods in which 1311600118 are conveyed through successive acid and water baths and has for its object the roduction of a simple machine that w' be eflicient in its work and reduce the labor of handling incident to the process.

- The machine consists of a plurality of swinging horizontal bars mounted transversely with one unobstructed endand suspended from the other end tothe conveyor. Batches of coils are loaded on these horizontal bars hanging downwardly. and pass through the acid and water oaths. Durmgthe progress through the baths the mechanism may be given a vertical vibratory motion at various points in the passa e of the coils through the acid bath, there y shaking out air and scale from the coils, thus facilitating the pickling and assuring a more uniform product.

The foregoing and other features of our invention-will now be described in connec-.

tion with the accompan in 'drawin forming part of this speci cation in w 1ch we have re resented our. mechanism in its preferred orm after which we shall point out in the claims those features which we be lieveto be new and of our joint inventlon. Referring to the drawings, V Figure 1 is a plan view of our machine. Figure 2 is a side elevationthereof. Figure?) is an end view of the machine looking from the left or the load ng end.

Figure 5 is an enlarged view of the supporting member and the associated conveyor apparatus. 1

Figure 6 is a section 6-6, Figure-5, showing a fragmentary view of the conveyor chain. I

In the carrying out of our invention we provide a plurality of horizontal supportin members 1 pivotally suspended from one en to a member 2 mounted on a shaft 17 provided with rollers 3 adapted to rideon a rail or a track 4. The rollers 3 are connected toany suitable conveyor chain 10 and driven by sprockets 11 through a chain of gears 12 by a driving mechanism 13. The conveyor is suitably-- supported by a structural frame 20, and "passes over a plurality of vats 21, 22, 23, 24 and so guided by rails 4 and direction idlers 30 that the coils of wire 50 are passed through the solutions that may be placed in the vats. These vats may contain successive baths of dilute acid, water or drawing soap as may be desirable in the carrying out of any rocess of pickling.

I At the loading en of the conveyor the coils of wire may be delivered from the coiling machine over the end of an apron conveyor, not shown, so that the coil drops in a vertical position ready to be tied together. The ,coil is then rolled over on to the delivery conveyor shown in Figure 3 which operates at right angles to the main conveyor carrying the horizontal bars with theunobstructed ends where it rests against an adjustable upright 61.

After a predetermined number of coils are thus assembled in vertical position onthe delive conveyor, the conveyor is set in motion, 1t e ng driven by the motor 62, the plurality of (30115 are moved alon into the 'machine proper where one of the orizontal supporting members 1 is ready to receive the group of coils, it being in line with the axis of the delivery conveyor and adapted to enter through the center of the coils. It will be readily understood that in place of this conveyor we may use a car or other means for advancing a plurality of coils thus assembled to thell" position on the main conveyor, the only requisite to this invention being that the coils thus assembled must be arranged at right angles to the conveyor with their centers in line with the horizontal bars with the unobstructed .end. As soon as the coils are in place on the supporting member 1 the conveyor 10 starts to move, lifting the coils of wire off the delivery conveyor or car and carries the coils on their path through the successive baths.

This action of loading is repeated, and may be continuous or intermittent de ending on whether it is desirable, to loa and unload from the same end or opposite ends of the machine. If the plant is designed so that it ispreferable to load and unload from the same end of the machine, the coils pass through the baths and are returned back overhead to the point of beginning where the loading conveyor or car must be run in the reverse direction will be readily understood.

In the preferred modification shown we have illustrated a similar conveyor at the unloading or delivery end. .This is a conveyor similar to the loading conveyor comprising an endless conveyor provided with adjustable rests 71 against which the coils may stand when being unloaded. Any simple conveyor may serve for the purpose, the. one illustrated being driven by the mechanism 72 or we may elect to use a car or wagon for the purpose. The main conveyor carrying the horizontal sup orting members 1 comprises two conveyor c mins 10 which in the form shown consists of links 15 pivoted together and provided at these joints with rollers 16. These rollers ride on tracks or rails 4 and the path changed by means of direction idlers 30. The path of the supporting memhers 1 is easily. followed in and out of the various tanks or vats by referring to Fig ure 2. Spaced conveniently are connecting bars 17 which are provided with rollers 3 similar to 16. On these bars are pivotally supported members 2 from which the supporting bars 1 are hinged, these bars 1 being suspended from one side ml and therefore have one unobstructed en ready at all times to receive the coils of wire, as will be readily understood by referring to detail, Figure 5. V

In order to make the pickling more rapid and uniform it may be necessary to verticallv vibrate the coils while they are passing through the acid in vat 21. In order to accomplish this we provide sections of the rail or track 70 pivoted at one end to the rail or track 4 the opposite end being connected by sup orting ro 71 to a frame 72 which is ivoted to the structural frame 20 at 7 3 the rec end of the frame 72 adapted to ride on a cam 74. which causes the oscillating motion desired, as will be readily understood by referrin to Figures 1 and 2. These cams are rotate by any source of power, or may be connected by belts 76 to pulleys 77 driven by one of the idlers 30.

In the usual carrying out of our pickling process, acid bath is in tank 21, washing water 22, clean water23, and drawin soa in 24 but we may use an other com inations known to those skilled in the art. Although we intend to wash the coils after pickling by immersion in water, this cleansing water may be applied by an overhead spray which can be arranged over the tank in any convenient manner as may be desirable.

We wish it distinctly understood that our machine for ickling coils of wire or rods herein descri 'd and illustrated is in the to unload as.

form in which we desire to construct it and that changes or variations may be made as may be convenient or desirable without departing from the salient features of our invention and we therefore intend the following claims to cover such modifications as naturally fall within the lines of invention.
