therowiof tanks and are supported by a pluralityof sprockets 6 mounted on a plurality .of transversely disposed shaft-s 7 journalled in suitable bearings 8 mounted on the framework 1. Mounted upon a .framework extension 8 is a slack take-up device ,9 (Figure 1) for the endless convey- 5 or chainsfr; The sprockets 6 supporting the lower laps'of the conveyor chains ,5 are ar- .ranged, .asclearly illustrated in Figure 1,

for the purpose of automaticallyv delivering and removingthe articles to be pickled in consecutive .order in. the tanks 2, 3: and 4;.

Connecting the two endless chains 5 at spaced intervals are a plurality of trans- .versely disposed rodsor connecting bars 10 ,on each of which a pair of spaced carriers .are pivotally..1nounted. .Each of the improved carrierscom rises a shank portion 11 having integrally ornied thereon at right angles a pairloflparallel brackets or arms 12, each of which is provided with a plurality of integral, upwardly projecting spacing teeth: or lugs 13. The carriers 12'13 are arranged in pairs and pivotally supported on the respective connecting rods of the endless conveyors 5 so that said pivoted carriers will hang by gravity in a substantially vertical position during their path of travel through the machine. The car-.

riers are provided with the spacing teeth 13 to permit a plurality of rim strips or ring strips to be carried by each pair of carriers with said strips positioned in two parallel layers and in spaced parallel relation. Two

sets or pairs of the carriers are adapted to frame is a reducing gear 14 connected to a suitable power source and having a sprocket 15 mounted on the shaft thereof for the purpose of driving an endless chain 16. The

drive chain'16 is also trained around a sprocket 17 securely mounted on a transverse shaft 18 also having a pair of the sprockets 6'mounted thereon for the purpose of transmitting a drive to the endless conveyor chains 5. Mounted on one projecting end of the transverse conveyor drive shaft 18 is a sprocket 19 around which an endless chain 20 is engaged. The chain 20 is also engaged around a sprocket 21 which is mounted on one projecting end of a transverse shaft 22 which is journalled in suitable bearings mounted on the discharge end' of the machine frame. Also mounted on the transverse shaft 22 intermediate the ends thereof is a sprocket 23 adapted to drive a chain 24. The chain 24 is trained around a sprocket 25 mounted on the middle portion of a stub shaft 26. The stub shaft 26 is journalled in a plurality of bearings'27 which are secured to angle members 28 mounted on the machine framework. Securely mounted on the stub shaft 26 are a pair of spaced kick-oil arms 29 fulcrumed intermediate their ends and spaced adjacent the inner sides of the conveyor chain carriers 1113, as clearly illustrated in 'Figures 3'and 5. .Rigidly secured to the upright angle members 23 are a plurality of brackets 30 to afford supports for an article-receiving platform comprising a plurality of angle irons 31, the ends of which are bent down in an inclined plane to afford a discharge apron 32. The article-discharge apron 32 is provided for the discharge of the rim strips and ring strips after they have been removed from the carriers as they pass through the platform 31. The apron 32 projects downwardly into a space, as indicated in Figure 4, provided for a receiving truck angle irons 34 which are secured upon a transverse table shaft 35 journalled in suitable bearings 36 on the machine frame 1, as clearly illustrated in Figure 3. The angle members comprising the stationary apron-32 of the platform 31 project downwardly between the spaced angle members 34 which comprise the pivoted ring strip receiving table. The table angle members 34 are connected by means of a transverse shaft'38. Secured to the ends of the shaft 38 are two bars 39 which project upwardly and have the upper endsthereof secured to arms 40 which are pivotally mounted on brackets secured to the machine framework 1.. Each of the brackets 40 carries a roller 41 which is adapted to track on a control cam '42 secured on a shaft 43. Mounted on one projecting end of the shaft 43 a sprocket 44 around which an endless chain 45 is trained. The chain 45 receives its drive from a sprocket mounted on one projecting end of the transverse shaft 18 which operates the conveyor chains. The cams 42 are formed and set to be operated from the shaft 43 so that at predetermined times in the travel of the conveyor chains the camsacting on the rollers 41 will swing the arms 40 upwardly, thereby causing the connecting bars 39 to move the pivoted table 34 from its horizontal. receiving position illustrated in Figure 4 into its elevated and dischargepos'ition asillustrated in Figure 5. A supply of ring strips which have been deposited upon the table 34 will be discharged by gravity from said table when in its inclined position into a ring strip receiving truck or container 46 which is adapted to be moved into the machine adjacent the truck 33 as illustrated in Figure 4'. The cams 42 are so timed that they act to hold the table 34 in its inclined discharging position during a period sufficient to permit a quantity of rim strips to be removed from two sets of carriers and de posited on the platform 31 to be pushed onto the apron 32 from which said rim strips are adapted to be discharged by gravity into the receiving truck 33 before the cams 42 perha simounted thereon a pairof transverse :bars 47 to which a pair of carrier guides "and -stops48 are secured. The upper ends of the guides 48 are inclined'to permit the lower mitithe' pivoted-table 34'tobe returned to its normal horizontal 'ring stripreceiving position.

In "Figures 1 and '7, it will-.tbe'noted that the loadingend of the machine framework cornersaof .the carrier to track thereon as they are moved into a loading position (designated by the letter A) in Figure '7.

'Whenin loading position the carriers l lare adapted to be engaged against the stops or guides '48 tohold said carriers against swinging'inwardly while they are being loaded with rim strips or-ringtstrips.

The operation is as'follows:

The conveyor chains 5 which carry theimproved double-hook type carriers 11 are adapted to be operated from the power source'through the reducingggear lethrough the chain16 which is adapted to 'drive the transverse shaft 18 and the sprocket 17 engaged thereon. The pivoted or hanging" carriers of said conveyor chains are adapted .to follow a predetermined irregular path through the machine, said :path being 'de- 'riers are now'permitted to move into load ing position to permit an operator to load the same with a plurality of rim strips.

Aftertwo sets of carriers have'been loaded as described, with rim strips, thethird" set ofcarriers, when moved intoloading ,position, is loaded with'a plurality of ring strips. This process or method of loading-the car- .riers is 'followed by *the operator so thata group of two pairs of carriers is loaded with rim strips while an alternate group of one The loaded carriers arexconveyed through the machine from the loading position A towards the discharge end of the machine and follow an irregular path permitting the rim strips .and rin strips to be lowered and carried through the pickling tank '2 after which they are automatically'raisedand carried over into the cold Water or rinsing'tank 3 "from which 1 they are automatically elevate'd and carried over intothe'neutralizing'tank' l. From the neutralizing tank 4" the pickled rim strips'and vring [strips are and then downwardl -path through-the stationary p atform531't0 I permit the articles to be removed from the carriers and positioned in the field of Lop- "eratiou of the, two rotating kiek-oil'v arms 29 '-tion.
