4 Claims. l
The invention relates to washing machines and it has particular relation to a washing machine of the automatic type.
In the type of machine with which the invention is particularly concerned, a cylinder is employed which turns on a horizontal axis. This cylinder is adapted to receive the clothes to be washed and the machine is oi such character that the clothes are automatically washed. rinsed and centrifugally dried without being removed from the cylinder. Therefore, a mechanism is operatively connected to the cylinder for effecting such movements of the latter and control of the water sc as to obtain these results.
One object of the invention is to provide an improved construction of automatic washirg machine having a horizontal cylinder wherein the cylinder is journalled in bearings ol improved character so that the cylinder is free from any binding action that might otherwise resi'lt from misalignment of its axis relative to the drive shaft of the driving mechanism.
Another object of the invention is to provide an improved construction for supporting the' bearings so that during operation of the washer, the cylinder does not vibrate or move excepting for the rotary movement imparted to it.
Another object of the invention is to provide an improved means for mounting the operating mechanism and connecting it to the cylinder so that the mechanism may be easily and quickly disengaged as a unit for the purpose of facilitating assembly, repair and replacement.
Another object of the invention is to provide an improved form of cabinet and supporting structure for housing and supporting the mechanism and cylinder which is strong and durable in character and which may be manufactured and assembled eiiiciently and economicallyA ther objects of the invention will become apparent from the following description, from the drawings to whiclrit relates and from the claims hereinafter set forth.
For a better understanding of the invention reference may be had to the accompanying drawings wherein:
Figure 1 is a side elevational view illustrating a washing machine constructed according to one form of the invention;
Figure 2 is an end view of the machineas seen from the left end of Figure 1;
Figure 3 is a cross-sectional View on a larger scale taken substantially along the line 3-3 of Figure 2;
Figure 4 is a cross-sectional view on a larger scale taken substantially along the line 4-4 of Figure l;
Figure 5 is a detail view on a larger scale illustrating a junction of parts shown on a smaller scale in the circle in Figure 3;
Figure 6 is a cross-sectional view on a larger scale taken substantially along the line 6--6 of Figure l; and
Figure 7 illustrates the manner in which the driving mechanism is assembled with the machine.
Referring to Figures l, 2, and 3, the invention illustrated comprises a cabinet portion I0 which generally is employed for supportingpurposes and lor housing the operating mechanism, and a generally cylindrically shaped receptacle II in which the washing cylinder is placed. A tubular bar I3 is anchored in the lower part of the cabinet portion I0 and is also secured to the outer end of the receptacle II for supporting the latter and details of this arrangement will be set forth presently.
The cabinet portion I0 comprises a band I4 having vertically arranged side portions IS and I6 and a substantially semi-cylindrical upper portion II. At its opposite edges, the band, as best shown by Figure 3, has respectively inwardly turned flanges I8 and I0 and these serve to increase the rigidity of the band and also to provide attachment portions. The flange I3 overlaps the edge of a vertical wall 2l and is welded thereto to have the band I4 extend laterally from one side of the wall. It Will be noted that the edge of the wall is slightly oilset as indicated at 22 so that the flange lays substantially flush with the remainder of the W'all. The wall 2l, if desired, may have pressed out beads or ribs to increase its rigidity.
The lower edges of the band I0, as best shown bv Figure 2, are bent inwardly and under a bottom wall 24 as indicated at 25 and 26 and the lapping portions are spot welded. Similarly, as best shown by Figure 3, the lower edge of the wall 2| is bent inwardly under the bottom wall 24, as indicated at 2l, and the lapping parts are welded. This bottom Wall also has an upwardly turned edge ange 28 which may be 'welded to the lower part of the wall 2| and it similarly may have end anges projecting u=p wardly and Welded to the lower ends of the vertical parts I5 and I6 of the band I4. A rea-r cover 30 closes that side of the band I4 opposite the v. all 2| andthe edges of the cover may be secured to the flange I8 by means of screws 3l.
This cover may have suitable louvres 32 and the side portion I6 of the band I4, which is at the rear side of the machine, may have similar louvres 33 so that ventilation is provided. Similarly to the wall 2|, the cover may be reinforced by beads such as indicated at 34 to increase its rigidity. The compartment thus provided is extremely rigid and strong and in particular it should be noted that the band I4 greatly increases the rigidity and load bearing characteristics of the Wall 2|.
At its upper edge, the wall 2| is substantially semi-circular and substantially at the center of curvature the wall has an opening 35 to accommodate a driving shaft which will presently be mentioned. At the left side of the wall 2|, as seen in Figure '7, a driving unit 36 is provided, and this unit, as best shown by Figure 7, is releasably secured to the wall and to a flanged plate 39 by bolts 40. Nuts 42 on the outer ends of the bolts serve to anchor the unit on the wall, and it will be seen that by removing the nuts the unit may be removed.
A tubular sleeve 46 extends through the opening 35 in plate 2| and is supported at the right side of the plate by a disc il also secured to the plate 2l by the bolts 4l). Preferably the sleeve is welded in position. Beyond the disc the sleeve has, on its outer surface, a spherical bearing element 48 and this element is engaged by a spherical socket member 49 which is fastened at its outer margin to a concave disc element 50 in turn rigidly fastened to an end wall 5I of a cylindrical cage 52 employed in washing the clothes. The disc element has a free-wheeling device 53 secured thereto which includes a driving element 54 and driving rollers 55 operable to drive the cylinder when the element 54 turns in one direction and operable to permit the cylinder to turn freely in the opposite direction. A shaft 56 projecting from the driving unit 36 and through the sleeve 46 has a square driving end 51| projecting into a similarly shaped opening in the driving element 54 so that the latter is driven.
From the foregoing, it should be apparent that the cylinder 52 positively is driven in one direction and is free to rotate in the other direction and that the driving unit 36 may be removed easily by removing the nuts 42 and then pulling the mechanism away from the wall 2|. Whether or not the unit is in place, the disc 50 on the cylinder 52 in conjunction with the socket member 49 seals the end of the sleeve 46 and thus water in the receptacle Il can not escape.
The unit 36 has a pulley 51 driven by a belt 58 in turn driven by a pulley 59 on the shaft of a motor 60. This motor is supported on a base 6| fastened to two supporting plates 62 of inverted U-shape respectively located adjacent opposite ends of the base. One leg of each element is fastened to the vertical and bottom walls 2| and 24 and to an end of the tubular bar or rod |3 by means of a bolt 63 threaded into a bushing 64 disposed in and welded to the end of the bar. Hence, in Viewing Figure l, it should be understood that the legs of the tubular rod are fastened to the lower part of wall 2| and to wall 244 and respectively to U-shape plates 62. These U-shape plates also have their outer legs welded as indicated at 65 to an edge flange 66 on the base 24.
The receptacle Il is generally of cylindrical form and its upper portion substantially corresponds in curvature to the upper part I1 of band I4. At the wall 2|, the receptacle has an inwardly turned flange 10 which is secured to the wall 2| by means of fastening devices 1| spaced suitably around the edge of the receptacle, and a rubber gasket 12 is provided for sealing purposes between the flange and wall.
The outer end of the receptacle has a radially disposed wall 14 and this wall at its center has an opening 15 through which a tubular element 16 extends. The latter element is enlarged inwardly of the wall 14 thereby providing an annular shoulder 11 and between the wall 14 and this shoulder a collar 18 is provided. At the opposite side of the wall 14 disc elements 19 and are provided and these are secured together by means of circumferentially spaced bolts 8|. The wall 14 and disc elements 19 and 80 are secured tightly against the collar 18 and the latter against the shoulder 11 by means of a threaded cap 83 threaded on the outer end of the-tubular element 16. From this it follows that the tubular element 16 is rigidly but releasably secured to the wall 14.
The outer disc 80 has an edge flange 85 of arcuate shape so as to fit the tubular rod or bar d3 and this bar extends upwardly and around about half of the flange 85 and along the contact between the rod and flange, the parts are welded. A cover 81 is fastened over the disc 80 by means of a screw 88 so as to enhance the appearance of the construction.
Inwardly of the wall 14, a reinforcing disc 90 is provided which may be welded adjacent its outer edge to the Wall. This disc at its inner edge has an opening for receiving the element 16 and preferably an annular collar 9| is provided in the opening to obtain a longer bearing support. Inwardly of the disc 90, a bearing sleeve 94 is provided on element 16 and the outer surface of this bearing element is spherical and contacts a spherical socket 95 secured to a disc element 96 which in turn is fastened to the outer end wall of the cylinder indicated at 91. In connection with this spherical bearing, it should be appreciated that the cylinder 52 can turn with the spherical bearings 48 and 94 and at the same time a self-aligning effect is obtained since the cylinder can move universally at either end about the spherical bearing.
Between the horizontal leg portions of the bar I3, a channel-shaped bar or shoe 98 is provided and this is secured to the two legs of'the bar by means of bolt type fasteners 99 having nuts |00 on their lower ends. As best shown by Figures i 1 and 6, the shoe 98 has a pair of adjustable stud type supports |00 each of which extends through a bushing |0| and through an opening in the upper wall of the shoe. A lock nut |02 on the upper end of the stud serves to lock it in position. The bushing |0| is welded in place and if the nut |02 is loosened and the stud turned, the verticalv position of the stud may be thus varied and the machine thus raised and lowered on the floor. Similar adjusting studs |05, as shown by Figure 3, are provided on opposite ends of the bottom wall 24. From this it follows that the four adjustable points of support are provided to obtain a level support for the machine.
From the foregoing, it should be evident that the cylinder 52 has a self-aligning bearing at each end and that each end is firmly supported by strongly reinforced structural elements so as thereby to avoid vibration. It is evident also that while these results are obtained the entire assembly may be assembled and taken apart easily, and in particular that the receptacle cage 52 and unit 3B may be easily installed and removed. While assembly and disassembly are thug facilitated, a strong and rigid structure is obtained and this is important in order to withstand centrifugal and other forces involved during operation of the machine. The structure generally is disclosed and claimed in my co-pending application, Serial No. 628,839, illed November 15, 1945. 1
The receptacle Il has in its front wall, as best shown by Figure 4, a clothes inserting opening and a door |05, and around the door opening, a rubber sealing element |06 is provided which is shaped to fit the door. At its upper edge the door is hinged as indicated at |01 and at its lower edge a suitable handle |08 and locking element |09 are provided. In a large portion of the door, a glass panel ||0 is provided so that operation of the cylinder inside m-ay be observed. While it isnt shown, the cylinder 52 also has a door which may be brought into coinciding relation to the door |05 so that the clothes may be inserted and withdrawn. The walls of the cylinder may be perforated as indicated to allow desired flow of water through the cylinder.
Although only one form of the invention has been illustrated and described in detail, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the appended claims.
What is claimed is: 1. A washing machine cabinet structure comprising a vertically arranged wall having a substantially semi-circular upper edge, a band of sheet metal disposed at one side of and transversely to said wall along the vertically arranged side edges and upper edge of the latter and having a vertical ange overlapping and fastened to the opposite side of the wall, a bottom member extending between the lower ends of the band and fastened vthereto and to the lower edge of said wall, a transmission mechanism secured to the wall on the side encompassed by said band, and a clothes washing receptacle fastened to the wall at its opposite side, and washing mechanism housed in said receptacle and driven by said transmission mechanism.
