14 Claims.

This inventionrelatestoa washing or tumbling barrel for treating various-small articles with a l quid to wash them, or clean orotherwise treat them, as with water containing an acid or other treating or cleaning material, such as soap and the like, and has for an object to provide a construction including an improved means for removing the liquid from thebarrel after treating the articles. More particularly it has for an object to provide a construction in which when thebarrel is rotated in one direction the liquid is retainedwithin thebarrel for-washing or treatingtthe articles, and when the barrel'is rotated in the opposite direction this movement will act to automatically remove the liquid from the barrel.

With the foregoing and other objects "in view we have devised the constructionillustratedin the accompanying drawings forming a part of this specification.

In these drawings:

Fig. 1 is a side elevation of the device-showing it'in operative position, with'parts broken away to more clearly-show the construction;

Fig.2 is a rear elevation looking from the right oft-Fig. 1;

Fig. 3 is a partial side elevation and 'partial longitudinal section on a "larger scale showing the mounting for the barrel or receptacle;

Fig. 4 is a view looking toward the open side of the jacket portion of the barrel or receptacle, with the barrel proper or'body of the receptacle removed;

Fig. '5 is a'longitudinal section thereof'showing the closed end portion of the body of the-receptactic seated in the jacket and in side elevation, an

Fig. 6 is a detail section substantially on line 3-6 of'Fig.-4.

Our improved washing'device comprises anupright base in which is mounted a housing H to swing in the vertical plane about a horizontal pivot shaft I2. Mounted in this housing is a hollow shaft 13, the shaft being mounted in suitable antifriction bearings l4 and I5. Bearing l 4, however, instead of being directly on the shaft s on the outer side of the hub 16 of a supporting flange 11 mounted on the shaft. The "construction of the housing and the mounting for the bearings and means for driving the shaft are substantially the same as that disclosed in the patent of Leslie WjBarnes, No. 2,353,637, is-

sued July 18, 1944, except that in the present case as the shaft is hollow and contains a pipe or conduit l8.for conducting liquid from the container, as will later be described, the shaft and this'conduit must project from thehousing and therefore instead of the housing being closed at the end of the shaft, as shown in the prior application, the housing has an opening forpassage of the shaft and conduit, and to prevent leakage of oil from thehousing a suitable seal l 9 is'placed around the-shaft between the bearing I5 and the openingin the housing. Otherwise the housing construction and arrangement and'the mechanism for driving the shaft is substantially the same as that shown in the'prior application mentioned. This comprises a wormgear 20 mounted on the shaft and secured to it meshing with a worm 2i at the top side of the gear on a drive shaft 22 extending transversely of the housing, Which-shaft is driven'by a pu1ley 23 through a V-belt 24'from an electric motor -25. The'lower side of the-worm gear 20 runs'in abath of oi12'6 in'the lower part of the housing and-carries this oil to theworm 2! by which it is thrown'laterally against the inner walls of the housing and which conduct it to the antifriction bearings as described'in said prior application.

The'fiange I! mounted on the shaft-carries'the washin barrel or'receptacle for the articles to becleanedor treated. This barrel indicatedat "21 includes a receptacle comprising two sections,

that is, the'barrelproper'or'body section 28 and the jacket section '29. The body-section 28 "is closed at its larger end and enclosedin the jacket section 29 but has any desired number of small perforations 30 through thewall of thebody section to form communication from the'interior of this section to the spaoe'in the interior of the jacket, the jac'ketbeing somewhat larger than the body section 'to form "a space 3|. The end wall-32 of the jacket is spaced from the-bottom or end wall 33 of the body section by any suitablemeans such as extensions 34 on th end of the body-section into which the securing "screws $5 are threaded. Th open side of the jacket'is closed by the inwardly extending flange 36 which may beformed by'bending in the free edge of the jacket after the section 28 has been secured therein, or it could 'be a separate flat member welded or-otherwise fastened to the sidewalls of the jacket. Its "free edge may also be welded at Site the member 28 or otherwise packed to make a "liquid-tight connection to prevent leakage of liquid from the receptacle. The openings wform a communication between the space in the body :28 and the space 31 for "transfer and circulation of the liquid between them. The body section 28 is preferably polygonal in cross section and comprises any desired number of flat sides 28a made of flat strips of metal secured together at their edges by welding or other suitable means.

The conduit or pipe iii in the hollow shaft leads to the container, its inlet end leading from the space 3| between the jacket and the body section 28 at the center thereof, and the entrance to this conduit is above the normal level of the liquid in the container, indicated at 38, So that the liquid will be normally retained in the receptacle. Located between the end wall 33 of the body section and the end wall 32 of the jacket are means operative by rotation of the receptacl in one direction to carry liquid to the entrance to the conduit 18 but ineffective to do this when the receptacle is rotating in the opposite direction. In the present construction it comprises a series of curved vanes 39 extending radially from the axis of rotation, or that is the entrance to the conduit, along the inner surface of the end wall 32 of the jacket to the side walls of the jacket, and they are curved so as to be concave-convex with the concave sides all facing laterally in the same direction. On the free edges of these vanes and spaced from and preferably substantially parallel to the end wall 32 are cover or side walls 49 stopping short of the next forward vane for the outer portion thereof toward the side walls of the jacket, as indicated at 4| Fig. 4, but thus providing with the end wall 32, the vane 39 and wall 40 a sort of bucket arranged with the open side 42 facing laterally. It will now be seen that if the receptacle is rotated counterclockwise, as viewed in Fig. 4, the liquid merely runs outwardly along the outer convex surface of the vanes 39 and is thus carried away or prevented from entering the conduit I 8 as the vanes move upwardly on the right hand side of the axis, but if the receptacle is rotated clockwise, as viewed in Fig, 4,

the liquid enters the open sides of the buckets and is retained therein, and as these buckets move upwardly on the left hand side of the axis the liquid will flow along the concave side of the vanes 39 and will be conducted to the entrance to the conduit l8 and will be carried from the receptacle. To facilitate the flow of the liquid into th conduit it is preferred to carry the inner ends of the vanes 39 part way across the entrance to the conduit and also a short distance into the conduit, as shown at 43 Fig. 5.

Thus when it is desired to wash or treat the articles the device is tipped to the proper angle, as indicated in Fig. 1, and the desired amount of liquid poured into the container through the open end thereof to brin it to the proper level. container is then rotated counterclockwise as viewed in Fig. 4 for any desired length of time. After the articles have been sufliciently washed or treated the barrel or container is rotated in th opposite direction or clockwise as viewed in Fig. 4 which operation will cause the buckets and curved vanes 39 to pick up the liquid and carry it to the conduit by which it is conducted away and discharged, and the operation is a very effective and rapid one.

To facilitate collection of this liquid an upright trough 44 ismounted on the rear side of the base ID by any suitable means such as the bolts 45 and has an open side 46 facing forwardly and the container into which the free end 41 of the conduit l8 projects, and the trough may be curved and the side walls 48 be carried forwardly sufiiciently so that the end of the conduit projects into the trough in all positions of the container and th shaft to prevent splash- The ing of the liquid. An outlet 49 is provided at the lower end of the trough discharging into a I suitable conduit, not shown, leading to a sewer or some suitable container, not shown, as desired. The end of the conduit may have a drip washer l8a to prevent liquid running back along the outside of the conduit when the barrel is tipped to dumping position.

Any suitable means may be provided for swinging the housing and the receptacle about the pivot shaft i2 to bring the receptacle to the proper angle for treating the articles or for inclining it with the open end downwardly for discharging the cleaned articles from the receptacle. In the present case this comprises a rack 50 mounted on the housing and meshing with a worm 5i mounted in a suitable bracket 52 and operated by a hand crank 53.

The device may be made of any suitable material such for example as stainless steel or other material to withstand the acids or other liquids used in the cleaning operation. The base It) may have in it one or more compartments covered by closure 54 for the control mechanism for the motor including starting relays, reversing switches, etc., not shown, or the starting and control switches including the reversing switch may be mounted at any suitable location on the base where they are easily accessible. This device eliminates the necessity of using valves and other similar apparatus, or as in some constructions the discharge of the liquid to the floor or around the device, and thus protects the device and nearby articles from injury by the liquid. As indicated, in washing the articles the device is merely rotated in one direction during which the liquid is retained in the receptacle and then after the washin or treating operation is completed all that is necessary is to reverse th direction of rotation of the barrel or receptacle and the liquid is quickly and automatically removed from the receptacle and discharged to the desired location. During this operation rinsing water may, if desired, be poured into the receptacle by hose or other suitable means and continuously carried from the receptacle by the rotating movement, thoroughly rinsing off the treating liquid.
