WASHING MACHINE.

Original application filed March 14, 1919, Serial No. 282,585. Divided and this application filed. August I 22, 1919. Serial No. 319,074.

To all whom it may concern:

Be it known that I, OGLESBY ALLEN, J12, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in washing machines of that general type which embraces a clothes receiving cylinder that is contained within the tub and is adapted to be turned or rotated in the wash water for bringing water, in which the cylinder is partially submerged, in contact with the clothes in said perforated cylinder.

The invention relates more particularly to a novel means to rotatively support the cylinder in the tub walls, constructed to permit the cylinder to be lifted out of the tub when desired, and to an interlocking connection between one of the cylinder ends and a power shaft or trunnion which receives power. from an external source, so constructed and arranged as to interlock the power shaft to the cylinder in a manner to permit ready disconnection of the parts when the cylinder is to be removed from the tub.

The invention consists in the combination and arrangement of the parts shown in the drawings and describe in the'speclfication, and is pointed out in the appended claims.

In the drawings,

Figure 1 is a vertical section of a washing machine, with the tub and cylinder in elevation showing my improvements applied thereto.

Figure 2 is a vertical section on the line 22 of Figure 1.

Figure 3 is a perspective view of the power trunnion or driving shaft which 1s mounted in hearings in the tub wall for driving the cylinder.

Figure 4 1s a perspective view of the bearing bushing or support in which the power shaft is rotatively mounted and which by one end of the cylinder is supported.

Figures 5 and 6 are endelevations and edge elevations, respectively, of the driving member which is fixed to one end of the ranged in this regard.

cylinder and adapted 'for driving connection w1th said shaft or trunnion.

As shown in the drawings, 10 designates the tub which may be of any suitable shape. It is shown as rectangular in plan and has a bottom wall 11 and a removable cover 12 and is supported on legs 13. 14 designates a perforated clothes receiving drum or cylinder within the tub provided with a suitable clothes receiving opening, not shown. It comprises end walls 15 and 16 and a circumferential wall 17 that is perforated or made of open work by any suitable constructlon which permits water to readily flow into and out of the c linder. The machine herein shown is of that t pe in which the cylinder rotates continuous y in one direction and is reversed and rotates in another direction, but m aiy be otherwise ar he operating mechanism for the cylinder is not shown but maybe of that tyIpe illustrated in my prior appllcation for nited States Letters Patent Serial Number 282,585, filed on the fourteenth day of March, 1919, of which this application is a division.

The cylinder is supported from opposite Walls of the tub through the medium of a trunnion 18 and adrive shaft 19. The trunnion 18 is fixed to the one end wall 16 of the cylinder in any suitable manner, as by means of a plate 20, and is seated in an upwardly opening recess of a stud bearing 21 that is fixed to the adjacent wall of the tub and extends inwardly through the tub wall towards the cylinder. shaft 19 is elongated to constitute a drive shaft. It is provided at its inner end with an enlargement or head 22 that is slotted at 23 in a plane parallel to the axis of the shaft to give the shaft a general fork shape. Said driving shaft 19 is mounted in a bearing bushing 24 shown in detail in Figure 4 and in section in Figure 1 that extends through the adjacent tub wall. The bearing 24 is provided with an attaching flange 25 that lies against the outer face of the latter tub wall and may be fixed thereto in any suitable manner, as by the rivets 26. Said bearing 24 extends inwardly through said latter tub wall from the attachirg flange 25 towards the cylinder and is form with an enlarged bore at its inner portion 27 to receive the slotted head 22. Said inner end portion 27 of the bearing 24 is notched at its upper side M28 in a plane parallel The- ' said shaft extends.

end of said shaftis fixed a bevel gear wheel to its axis. In the outer end 29 of said bearing the reduced portion of the shaft 19 is rotatively mounted, and the shoulder between the reduced and enlarged part of the shaft engages an internal annular shoulder of the bearing 24:, as shown in Figure 1, to thereby limit the outward axial displacement of the said shaft in said bearing. In assembling, the bearing is first fixed in place and the shaft is placed in the bearing by inserting it outwardly through the bearing from within the tub until the shaft is arrested by engagement of said shoulders. Said outer end portion 29 is threaded to receive a cap of a stuffing box through which To the extreme outer 30 which meshes with a driving pinion 31 that is fixed to the upper end of a driving shaft 32 that may be connected to a source of power through the operating mechanism shown in my aforesaid prior application.

33 designates a driving member, which comprises a plate ordisc 34 that lies flat against and is adapted to be riveted or otherwise rigidly secured to the power end wall of the cylinder, and an outwardly extending flattened lug 35. The said notches 23 and 28 of the shaft 19 and bearing 24, respectively, are of substantially the same width and said flattened lug 35 is of such width that when the notches 23 and 28 are brought into register by proper rotation of the shaft 19, the driving lug 35 may pass through the notch 28 and into the notch 23 to effect a driving connection between the shaft and the cylinder driving lug. The parts are shown as thus assembled in Figure 1 of the drawings and so long as they remain assembled power can be transmitted to rotate the cylinder through said notched driving shaft and the driving lug. When it is desired to lift the cylinder from the tub the shaft 19 is rotated to bring its notch 23 in line with the notch 28 of the bearing 24 and at this time the driving lug of the adjacent end of the cylinder is free to be moved upwardly and disconnected from the driving means. The trunnion at the other end of the cylinder, by reason of the opening at the top of the stud 21, is always free to be moved upwardly from said bearing.

lit will thus be seen that the cylinder may be rotatively mounted in and removed from its bearings and that the power or driving meaeeo shaft is connected to the c linder by a very simple means which permit of the parting of said shaft and the cylinder when the cylinder is to be removed.

In order that the trunnion 18 and the driving lug 35 may be accurately guided into their bearing seats 21 and 24, respectively, the end walls of the tub are provlded on their inner faces with guide ribs or flanges 38 herein shown of angle bar construction that are riveted or otherwise suitably secured to said tub walls. The said guide ribs or flanges converge toward the seats for the trunnion 18 and stud 35 and extend entirely to said seats -so that when the driving lugs are entered between the upper end of said flanges or ribs they are automatically guided into their bearings.

I claim as m invention:

1. In a washing machine, the combination with a tub, a clothes drum therein an angular drive stud projecting from the 'end wall of the clothes drum, and a bearing sleeve extending through and flanged to be attached to the outer side of the tub wall and notched at its inner end, of a drive shaft journaled in said sleeve and having a slot to register with the notchof the bearing sleeve and to interlock with said drum stud Within the notched inner end of said bearing sleeve and externally shouldered to engage an internal shoulder of said sleeve. 2. In a washing machine, the combination with a tub carrying on its opposite walls inwardly extending bearing members which are notched at their upper sides, and a drum within said tub, of a trunnion at one end of the drum to engage one of said bearing members, a polygonal drive lug fixed to the other end of the drum to enter the other bearing member, and a drive shaft. rotatively mounted in said latter bearing member and having an enlarged inner end that is slotted to register with the notch of its bearing member and a reduced outer portion that is rotative in a reduced part of the latter bearing member, said polygonal drive lug being adapted to pass through the notch of the said bearing member and into and interlock with the slot of said drive shaft.

In testimony whereof I" claim the foregoing as my invention, I hereunto append my signature at Chicago, Illinois, this 15th day of August, 1919.

OGLES-BY ALLEN, JR.
