Taking up the above vparts in sequential relation,vthe referplaces in a container'or containers 2preferably aV series or group of containers, articles to be Washed. Whenva sufcient number of containershave been-supplied Witlrarticles to. be vvashedthe carriers are' caused to advance toward a suds tub 31. Inithismovement, which asshoivn 1n Fig. 1 1s toward the right, the carriers V*may be movedalong 'the overhead track 4 1n any desired manner.v

" Each carrier, as Will hereinafter"bede scribed, is equipped with an electrical motor; 8, current tolWhich is Ysupplied from Wire'll l through trolley pole. l The trucks and their carriers are moved-towardv ay tank 3 for conf Y taining a cleansing solution., While the carriers are-advancingtoWard and prior to introduction of suds? to the tub 3, an attendant in charge opens the entrance gateof the tuby (which gate Willb'e hereinafterdescribed in detail) to permit the entrance of the series or groupof carriers. VVVith Vthe'group of carriers assembledivithn tub 3 (the respective motors of each travellingtruckof course having been stopped bytheyattendant in charge) ther-said attendantV closes the V"en-V trance gate, and opens valve ofsupplyV pipe v 7 for the'lling of tub 3With cleansing liquid or suds. With the group lof carriers,- containing articles to b ewashed,y arranged with Vin tub 3, the operator at tub 3 now starts the motors` 8 (one. foreach carrier) to .vertically reciprocate the plungerY 9Ain each carrier 2. Thus,asl the plunger 9 of each carrier is vertically reciprocated Within a carrier, the suds are caused to enter and egressthrough the apertured Walls of the container.4 llhenV this reciprocating, plunger operation is con-y tinued for a desired length of-time the oper-- ator in'charge Vwithdraws the cleansing liquid from tub' 3; and continues the operation with a rinsing liquidyopensl the'exit gateV of the tub 3; and advances thjegroup of carrlers ypreviously contained 1in'tub 3.

Overhead track fthe Washing operation materially. A vdey l Preferably arranged -in Vsubstantially elliptical form, as clearlyillustrated in Fig.

1, are a pair of tracks 10.V VThese tracks 10,

as very clearly shown in Fig. 6, are formed of I-beams and are arranged'in spaced relation. vThe tracks are continuous in continuityand are adapted to have tracked thereon a plurality of trucks Which support thecarriers 2.I i VSince"allthetrucks and since all thejcarriersare of the same construction a description of one Will suiiice, and such description of'truck and its complemental carrier Willnow be given. i

the motor`8wpreviouslyreferred tof This'V detail Fig. 104.V Shaft; 20 has fixed thereto al carrier 2, which is 'preferably of sheetmetal Vand perforated as at V23. This carrier shafty 2O is provided at its;bottomA with a spherical `meinber24 and'is provided vat its top 'with spherical member 25. The spherical member -Y v 25 isarranged for rotation Within a casing 26 Vcarried by the spring supported platform 27,V as Ycarriedby each I=beam 11. `Worin 17 is in mesh `.with a` Worm wheel 28 turnably mounted on a-shaft30.V The-worm.wheel1 carries a ratchet A adaptedvto `be turned in one direction by a paWl29 carried byanf arm 35 i'keyed to theshaftpseedetailzFig.' 9.

Shaft 30 k*is'in turn provided With a pair' of. i

Thus, as the shaft 20 is rotated the pawl 29 which is fixed to shaft 30 cooperates with 'itsfratchet wheel to maintainthe. movement of shaft 20 1n the proper direction forreciprocating a plunger 9. p i

i n ..Suds tu?) A While a carrier or carriers are arranged within the tub 3 it is necessary that cleansing and rinsing liquid be introduced, which is accomplished through valve connection 7. It

is also essential that when theV carriersare about to be advanced for rotarymovement that the cleansingliquidbe removed, and for Y this purpose valved outlet pipes 37Y arepro-v vi-ded. At each end ofthe tub 3 there is provided a vertically movableV gate, best seen in Fig.4, it being understood that the gate at each end of the tub isof duplicate'construction so thatlit is merely necessary to describe one of these gates. The bottom 33 of the tub 3, and referring now more par-- ticularly to the exit end of the tank (although the entrance end of the tank is of similar construction) is provided with a flat,

cross piece 39 provided with a facing 40 of rubber, canvas, or other suitable material in order to prevent leakageof cleansingliquid when the gates are closed. `Movable vertical ly ina downward direction is a gate 4l comprised of a piece of sheet metal which in cross section, as clearly shown in Fig. 4, isof inverted V-shaped configuration. The spaced faces of the gate are maintained apart'by means of struts'42. Theouter face of the gate is provided with a pair of spaced rack bars 43. These rack bars each have meshing therewith at the lower ends thereof pinionsk 44 mounted upon a horizontalshaft 45. lThe shaft 45 in turn is'connected withv a drive shaft 46 by means of a sprocket chain 47. The shaft 46 is provided with a hand wheel V48 by which motion may beimparted to shaft 46, thereby imparting motion l to I sprocket chain 47 and shaft 45 including gearV 44 to elevateV or lower a gate of the tub 3. As clearly shown in Fig. 5, the side walls of the tub'3 are provided with angle pieces 49 arranged between which and the V-shape gate are rubber, fibre or otherV packing mem-n bers 50. a. Station for centrifugal movement of carrier After the articles in the carriers 2 have been washed at which time the plunger .9,is

vertically reciprocated to thoroughly cause the cleansing liquid in tub 3 to commingle with the articles in the carriers, the valves ofV l the pipes 37 are opened to permit egress of the cleansing liquidV in tub 3. After the tub has been emptied thegates at each end of tub 3 are raised so` that those carriers Within the tubv3 may be passed to the stati0n'51for`ro- A.re

Thus, it is apparent thatthe upper and lower end of shaft 20 of each carrier whilefree Vto rotate aregsuspended or arranged against'lateral orlongitudinal'AL movement.' At this timek fthe attendant in charge reversesthe motor 8 any convenient vmechanism not shown inthe drawings so that the setv screws of connections 33 are first carrier 2, and the connections 33 thereafter secured to place with the plunger free of carrier 2. In orderto secure rotation of vertical shaft` 2O of each carrier 2 it isnecessary to;
