It is therefore among.the. advantagesofmy invention to provide a Washing machine which is self dumping; to provide a Washing machine which permits a reduction in manual labor; `to provide a Washing machinewhich eliminatesJ the use of conventionaldoors on the cylindrical sur; faces of the cylinder,k thereby eliminating klthe need of registry of the doors and eliminatingY the additional expense involved inthe manufacture of such doors; to provide awashing p machine which may be positioned so that the washed laundry may be dropped directly from. the` washing machine to a receptacle; and, to provide a wash-` ing machine of the character described, which mayY be manufactured economically and which will function emciently throughout its cycle of operation.
These and other objects and advantages will appear more fully in the following detailed description when considered in connection with the accompanying drawing, in which; 1
Figure 1l is an elevational View in longitudinal section of a washing machine embodying the fea# tures of my invention;
Figure 2 is an end elevational view thereof, partly broken away, and partly in section; and, Figure 3 is a detailed view, in sectionh of a door locking mechanism taken alongV lines lII-III of Figure 2.
With reference to the drawing and, in par# ticular, to Figure l, I show an Yembodiment of my invention in the form of a commercial washing machine comprising essentially 'an outer cylindrical container I and an inner container 2: The outer container is provided with an end wall 3. Reinforcing structural members tand@ are attached to the container l and to frames 6 and 1, respectively, and to apair of horigontahhan:
nels 3 which serveas-afbase forsupporting the outer cylinder l, Amain page t0. which. themachine is nii/@tally supgcrted comprises arbeiter; channelsci. and4 llt ..;;l`hese channels rest umn and are preferably attached to a iioor, orsimilar support. Near one end*v of each of the `Vchannels 9 and E@ isvattached brackets Il andml2respecl tively; which serve, asi-a `hinge .or Divan linnn whichgthe washing-machine may betppd .A hinge pin lextends through the bracket@V Il and I2 and through the pair of channels 8- to pin I3. This results in a tipping action of the` entire Washing machine.
For the purpose of introducing waterinto the ginal edge of the door 42 engages with the edge of the outer cylinder I to constitute a seal and thus form a water tight container. As shown in Figure 3, a bracket 46 is attached to the angle 5, and an eye screw 41 is pivoted to the bracket 4B. By means of a hand operated nut 48 and an extension plate 49 projecting from the door 42, a lock arrangement is provided for securing the idoor in closed position.' i 1o An end enclosure is also provided for the inner container 2. This end enclosure comprises a plate 5U having inwardly tapered edges 5I adapted to cylinder I, a conduit 2E extending through the plate 3 is employed. A portion of the conduit 2D may be of iiexible construction so as to permit elevation of the washing machine while main- Y taining the Water connection.
At the lower portion of the container`r I` is an outlet aperture 2 I. As shown in Figure 2, a quick dump valve of conventional type is utilized. Essentially, this valve comprises a sealing member 22 having a handle 23 attached thereto and pivotally mounted on a bracket 24 Ysecured to the container I. A hand operated latch 25 functions to maintain or release the valve from its engaging position, anda spring 26 normally maintains the latch 25 in locked position. Directly below the dump valve is a drain 2'I having an enlarged top portion 25 adapted to enclose the principal portion of the sealing member 22 of the dump valve. The drain portion 28 is disengaged from the cylinder I so as to permit tipping movement of the washing machine without accompanying movement of the drain.
Rotatably mounted Within the container I is the inner cylindrical container 2 formed of perforated sheet metal. The container 2 includes a plurality of ribs 23 suchY as are conventionally employed'in Washing machines of the cylindrical type. The container 2 is open at one end and is closed at the opposite end by means of a plate 3U. A trunnion or flange 3| engagesr with the closed end of the container 2 by means of being attached to inserted plates 32 fastened in the well of the V-shaped ribs 29. The Bange 3I is supported by a shaft 33 mounted in a bearing 3e held in a fixed position by means of a bracket 35 attached Vto the end plate 3. A pulley 35 keyed to the shaft 33 is driven through belts 3'! from a pulley 38 attached to a motor 35. The motor 39 is supported by a plate 43 secured to the upper surface of the channel 8. *o
In accordance with this arrangement, the ccntainer 2 may be driven from the motor 33 While the washing machine is in either a horizontal or tipped position.
To assist in supporting the free end of the container 2, I provide, near the freeV end of the container, three or more bearing supports 4i attached to the inner surface of the outer cylinder I and adapted to form a sliding contact with the outer surface oi the inner cylinder 2. These bearing blocks 4I may be composed of a suitable bearing material such, for example, as lignum vitae. These bearing blocks, when positioned in spaced relation, serve to remove the strain on the principal drive support for the container, and will reduce vibration of the container when the container is being rotated with an open end.
In order to form a Water-tight enclosure for the outer container I, I provide a door 42 having hinges 43 and 44 attached to the door and to the reinforcing angle 5 which circumscribes 'the container I. A sealing ring 45 lying within the marfrom the container 2.
engage correspondingly tapered surfaces at the end of the inner container 2. The plate 50 is supportedby a ange 52 forming a part of a shaft 53. The shaft 53, in turn, is rotatably supported f by a bearing` blockf54 attached to the door 42.
A collar 55 maintains the shaft 53 in proper axial position. This means of enclosing the end of the inner container 2 provides, in addition to the enclosure, a support for the end of the inner container 2.A this manner, it'is possible to rotate the inner container 2 at relatively high speeds for the purpose of semi-drying laundry by means or" expressing the watertherefrom by centrifugal force.
In the operation Vof th'e washing machine constituting an embodiment of my invention, the door 42 is opened and the dry laundry is positioned within the container 2. Thereafter the door is closed and aV desired quantity of water is introduced through the conduit A suitable detergent may be placed initially in the conf tainer or it maybe introduced through an additional rconduit (notfshown). The motor 39 is started and the inner container is rotated for the washing cycle. Ifdesired, the motor may be of a reversible'type 'so as to result in a given number of turns of the container 2 in one direction, and `a"`s'iiila'r numbern ofturns in the opposite direction. 'When the'washing cycle is completed, the dump valve is actuated allowing the water to run out of the container I. Thereafter, clear water is introduced into the container followed by a rinsing cycle. The dump valve is again actuated and the `water is permitted to run down the dr`a ir1 ,Throughoutthese operations, the container may be rotated continuously. If desired, the motor 39 may be increased in speed so as to dry the laundry, partially, due to centrifugal action. The door 42 is next opened and the J'aCk I4 is actuated to elevate one end of the washing machine. A receptacle maybe positioned at the outletend ofthe washing machine to receive the laundry which is ejected from the machine. Rotation of `the container 2, while the washing machine is in its tipped position, results in the Wet laundry being moved easily and quickly When all of the laundry is removed from the container the jack I4 is lowered and the machine is ready for a similar lcycle of operation.
As thus shown and described, it is believed apparent that I have provided a novel washing machine which constitutes a unique method of unloading laundry with its resulting reduction in manual labor and with an increase in eiciency and -reduction in the time cycle of operation. y WhileI have shown a preferred embodiment of my invention it is to be understood that it is susceptible of those modifications which appear obviously Within the spirit of the invention and as appearing in the scope of the appended claims. Having ythus d e sc :ribed my invention what I claim and desire to protect by Letters Patent is:z
