Figure 7 is a cross-section taken on linei -l 1 of Figure 2.

Referring to the drawings, the numeral it des= ignates a suitable supporting frame on which may be secured a bracket it provided with a forwardly extending central sleeve 82, integral with the rear wall it of bracket ii, for rotat=-- ably supporting a. revolving pump and .103:

chuck member it. For rotatably driving chuck pulley it through suitable reduction gearingas from a motor 26, which preferably is a; re

verisible type motor and which may be pertodically reversed by suitable well-known means to turn chuck it one or more revolutions alternately in one direction and then in the other direction. v

The chuck id contains a mixing and pumping chamber or compartment 28 in which is a paratively large central rear opening 22;

I" iii a centric with the sleeve 82, the chuck it being formed with a flange 28 about its opening. The flange 23 is arranged to project inside a :i. -r' 2d or slightly larger internal diameter on theater! ward wall of the bracket il to u 1 opening 22 with'a chamber 25 within the bracket ii and surrounding the sleeve i2. e're 23 may be formed with abeveled e 281101 seating a valve 21 to close the ope '22 from chamber 25, valve 21 being slibly and'rotatably mounted on an enlarged portion 53 p! the described.

sleeve I2. A shifting collar25 may be rotatably engaged with valve 21 and connected to valveoperating rods 36 operable, by a cross-piece 3|,

' normally held in valve closed position by

springs

32, 32, through an arm,3 3 secured on a shaft 34

iournalled inbrackets

35 and 36, which brackets may be used and located at any convenient point in the discharge duct.

The sleeve l2 may have a relatively large central passage l2, therein extending from the rear of bracket I and communicating with the interior of the washing drum, but having the lowermost point of itssmallest internal diameter above the normal fluid level whenv the washing drum is in use for washing. The enlarged end |2 of sleeve |2 may be constructed to provide a pocket l2 having perforations l2 at the bottom thereof for permitting overflow from the washing drum to pass down through drain 25*. The central passage l2 provides a convenient means for looking into the interior of the washing drum as well as providing free access to the interior thereof for various purposes, such as injecting treating materials, while the drum is rotating.

It has been found that by mounting the, drum 45 on the chuck |4 without the screen 61, the central passage or opening |2 may also be-utilized for supplying clothes to the drum. or for removing the clothes therefrom after they have been treated. This is particularly advantageous in that the clothes supplying and emptying Opera- 55 on one side (see Figures 2 and 6) of ribs 5|' open these are adapted to pump washing fluid from compartment 2| into chamber 25 from which the fluid may pass out of drain 25.

The front wall I4 v of compartment 2| is perforated as at 50, 50 between the vanes 49 whereby fluid may be delivered by flow under gravity,

between compartment 2| and the interior of drum 45 either while the drum is stationary or rotating. These areas are so arranged, however,

that comparatively large quantities of washing fluid will pocket itself'between vanes 49 in compartment 2| so as to flow out of the chuck opening 22 when valve 21 is open (see Figure 7) to empty drum 45 of fluid.

The interior of drum 45 may be provided with tumbler ribs 5|, 5| of a known shape and formation but preferably which are hollow (see Figures 2 and 6) and perforated at 52, 52 to permit drainage of washing-fluid from ribs when in inverted relation as at the top of Figure 6, and to permit circulation of the fluid through the ribs. A partition 53 in each rib forms a chamber 54 receiving washing fluid through perforations 55,

on counter-clockwise rotation of drum 45 and forcing that fluid endwise toward the rear of the drum under considerable force, the partition sloping, as shown, for this purpose, and the entions may be safely accomplished while the drum is either rotating or stationary. i

' Chuck I4 may be retained on sleeve I2 in on 'direction by an annularflange 40 secured, as by screws, on the edge 0f-sleeve .|2, and retained in the other direction by close proximity to the edge of flange 24 to the rear wall of the chuck as well as by the yielding pressure of valve 21 when it is in closed position. I

Adjacent the forward end of the sleeve l2, extending radially inward, there maybe hollow chambers 4|, 4| suitably apertured for a plurality of

rinsing nozzles

42,42, and

supply pipes

43 and 44. The

supply pipes

43 and 44 may both be used for supplying rinsing water or other washingfluid, orthey may be used for distinct purposes as will be readily understood. The nozzles 42 preferably are adjustable so that one or I more may be extended upwardly to project rinsing water or other fluid above the tumbling contents of the washer drum as will subsequently be The chuck |4 may be suitably constructed removably to retain therein a washer drum 45. For

example, chuck |4 may be formed with an'anlarged end of the chamber 54 being in registry with an orifice 56 in wall N of the chuck |4 whereby the fluid will flow into pump compartment 2|.

Other ribs 51, '51 are provided on the inner periphery of drum 45. These preferably extend angularlyor helically across the drum as shown to impel the contents alternately in opposite directions axially of, the drum as the drum rotates in reversed directions. These ribs may be hollow as shown and perforated on one side and a portion of the top thereof as at 51, 5'! so as to trap water therein upon clockwise rotation of drum 45, the ribs forcing water trapped therein through oriflces'56, 58 in the wall |4 into the pump-chamber 2| in a manner similar to that described with respect to ribs 5|.

The drum 45 may be removably supported in the chuck l4 and on

rollers

59, 59 on base frame It, engaging the outer periphery of the drum.

Aninlet for introducing water with soap, bluing or'other washing ingredients into the drum may be provided at 60 being formed in sleeve portion I2 of the bracket II and opening into the'compartment 2|. inside ofrvalve 21. Piping 6| may be connected to this inlet and to a supply chamber 62 into which water may be introduced by piping 63 controlled by a suitable valve (not 3 shown) chamber 62 having a removable slidable lid 64 whereby soap, bluing, etc. may be supplied to the water flowing through the same and through piping6| into the drum 45.

vTo secure and release drum 45 in the chuck an inflation valve 65 of the usual type used in inflating tubes, swimming belts, etc. may be arranged at the front of the drum 45 and may be connected by flexible tubing 66 to the inflatable tube or ring 46. 1

As is best shown in Figures 2 and 3, the drum 45 maybe provided with a suitable screen 61 for closing the forward end of passage I2 in the As best shown in Figure 7, theeompartment sleeve |2 when drum 45 is secured on the chuck H, as well as for holding the washed or treated articles within the drum at when; is removed from chuck it with such articles still inside. For this purpose screen 61 may be hinged at 68 and suitably locked in position as by a quickly releasable spring catch at 59. The screen 6'! preferably is shaped to avoid interference with free passage of fluid between the chambers in the vanes i and 5? and the pumping chamber 25. If desired, the drum as may be filled and emptied of articles to be washed or cleaned through a front opening '50 about which may be a flange H adapted to receive a removable cover I? preferably having a central transparent pane therein, through which the interior of the drum may be seen.

In the use of the machine for washing or treating clothes, either the clothes may be placed in the drum 45 through the opening l0 therein,-

while the drum is in place on chuck It, or a drum may be previously loaded with clothes, as for example at a loading station (not shown), through the large opening at the rear of the drum and subsequently secured in place on chuck it by means of the pneumatic ring as, the screen 67 being utilized to retain the clothes while drum is being lifted into position. As a guide for aligning the ribs 5i and bl with their respective communicating openings in the wall it of chuck It, suitable readily visible indicating marks may be provided at 45 on the chuck It and drum 45 (see Figure 1). When the drum is in proper position with clothes therein, and valve 21 closed as shown in full-lines in Figure 2, the machine may be filledwith sumcient washing or other fluids along with soap, bluing, etc., supplied through receptacle lilL'piping 6i, and inlet 60 to compartment 2| and into the main body of drum 65. Any overflow will pass through sleeve 82 to' the pocket l2 and into chamber 25 and drain pipe 25. During the clothes washing or treating operation the ribs 51, due to the arrangement thereof and the alternating rotational movement of the drum, will cause the clothes load to be shifted back and forth, thereby aiding a thorough agitation of the clothes, as they are tumbled about the drum.

For emptying the machine of washing or other treating fluid, valve 27 will be opened which immediately causes a large volume of water to flow out of the drum solely by gravity and not depending upon rotation of the drum. This is illustrated by full and chain-dotted lines in Figure 2. Thereafter while the chuck it is rotating the vanes 59 in compartment 2! pick up fluid flowing thereinfrom drum t5 and cause it to flow through the opening 22 into the chamber 25 in bracket H and cut the drain pipe 25. The construction of the ribs 5i and 51 is such that substantially every particle of fluid will be ejected from the drum as the latter is rotated alternately in diiferent directions. At the initial opening of valve 21 the fluid level will'drop instantly from a level substantially as shown in chain-dotted lines in Figure 2' to a level in line with the bottom edgeof the washing and rinsing operation the drum 45 may be removed bodily, with the clothes retained therein by screen er, and replaced by another drum previously filled with clothes to be similarly treated.

It is to be understood that the machine may be used for other purposes than. washing clothes.v

For example, it may be used for dyeing articles, in which case, the action of the

ribs

58 and 51 for removing the dyeing fluid during the fluid ejecting period without leaving a pool at the bottom of the drum'is particularly desirable for obvious reasons. This equipment may also be used for dry-cleaning machines using suitable cleaning fluids instead oi aster.

Modifications of theinvention may be resorted to without departing from the spirit thereof or the scope of the appended claims. For instance by enlarging opening 22 in comparison with the size of the drum it is possible to discharge all the water very quickly solely under action of gravity.
