WASHING MACHINE.

Specification of Letters Patent.

Patented July 18, 1922.

Application filed November 7, 1919. Serial No. 336,362.

To all whom it may concern:

Be it known that I, AnoLrH F. ANDERSON, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

This invention relates to washing ma chines.

More particularly it relates to washing machines of the power driven type.

One of the objects of the invention is to provide an improved washing machine.

Another object is to provide an improved Washing machine having its tub and operating mechanism entirely enclosed.

Another object is to provide an improved housing for a washing machine.

Another object is to provide a housed washing machine wherein the tub and operating mechanism are readily accessible.

Other objects and advantages will appear from the specification and claims.

An embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of a washing machine.

Fig. 2 is an end elevation thereof.-

Fig. 3 1s a section on the line 3-3 of Fi 2.

ig. 4 is a section on the line H of Fig. 1, and

Fig. 5 is an enlarged view of a section of the housing wall slides.

The washing machine comprises in general a pivotally mounted tub 5 which is oscillated by operating mechanism including a motor 6. The tub, motor and other movlng parts are completely enclosed by a housing 7. t

The housing has a base composed of four angle irons 8, bolted together at their ends to form a substantially rectangular frame. The base is provided with four depending casters 10, whereby the washing machine ma be moved about readily.

arried by the base are two end walls 11 and 12. Each end wall has an inwardly extending flange 13. These flanges strengthen the ends, form corner posts the housing and provide supports for the side wall and, cover guides to be hereinafter described. Each end wall may be made from a single piece of sheet iron or other suitable material.

The sides of the housing comprise two upwardly slidable walls 15 and 16 and the top is composed of a slidable cover 17 slidable downwardly behind the wall 16 and a fixed section 18. Walls 15 and 16 and cover 17 are each provided with a pair of handles 19, whereby they are readily moved to open and closed position. The slidable side walls, cover and fixed section each may be formed from a single piece of sheet iron or other suitable flexible material. They may also be corrugated or beaded, as shown, to lend strength thereto, and prevent buckling. Secured to and extending between the ends 11 and 12 are a pair of strengthening braces 20 and 21. A pair of strips 22 and 23 extend the entire length of and in spaced relation within the flanges 13 of the respective end walls 11 and 12. Strips 22 and 23 each may be formed of a single piece of strap iron or steel and are held in proper spaced relation relative to flanges 13 by spacers 24;. The strips and their respective spacers may be held together and to flanges 13 in any suitable manner, such as bolting, riveting or spot welding.

Flanges 13 and strips 22 and 23 form guideways for retaining and guiding the opposite edges of the sides and cover of the housing. Thus side walls 15 and 16 may be raised from the position shown by the full lines so as to allow access to the bottom of the housing and cover 17 may be lowered to allow access to the top of the housing. The side walls and cover slide within the guideways provided by flanges 13 and strips 22 and 23. They are prevented from springing outwardly by the flanges and from'falling or springing inwardly? by the strips. displacement.

The tub is pivoted to the end walls within housing 7 upon trunnions 25 and 26. Trunnions 25 and 26 project through open-" ings in the hubs 27 and 28, respectively, of spiders "39 and 30, secured to the respective end walls 11 and 12. The tub may be made of suit-able material, such as sheet iron and has an opening in its top provided with a removable lid 31.

The spacers prevent lateral Trunnions 25 and 26 project, respectively, into bearings formed in the hubs or spiders 35 and 36 which are secured to the opposite end walls of the tub. The tub is thus suspended on trunnions 25 and 26.

The tub is oscillated about its axis by an operating mechanism having an electric motor 6. Motor 6 is belted to a pulley 38 which is provided with a pinion engaging a gear wheel 39. Gear Wheel 39 has a link 40 pivotally connected thereto and through which it communicates motion to the tub by a crank 41. When gear wheel 39 is rotated by the motor the tub may be oscillated by link 40.

The operating mechanism is carried on a suitable bed plate 45 secured to the base of the housing. The motor is slidably mounted upon the bed plate and may be moved by an adlj usting screw 46 to vary the tension in the be t.

The operating mechanism is connected to and disconnected from the tub by a handle 50, which, through a train of beveled gears 51 controls a suitable clutch 52. When the handle is thrown in one direction the clutch interconnects crank 41 with thetub and when the handle is moved to another position it disconnects crank 41 from the tub.

A wringer 53 is positioned outside of and above the housing. It is carried on a standard 54 which projects through an opening in v the fixed section of the housing top and is secured by suitable means to end wall 11. The wringer rolls are operated by motor 6 through a gear wheel 55 which meshes with the pinion of pulley 38. Gear wheel 55 drives, through suitable beveled gears, a shaft 56 which is interconnected at its upper end to the wringer rolls by a suitable bevel gear train.

The tub and its operating mechanism are entirely enclosed by a housing. The danger of clutches or garments being caught in the moving parts is thus eliminated. The side walls of the housing can-be raised readily so that access may be had to the bottom of the tub and theoperating mechanism. The cover of the housing is slid easily to open position so that the top of the tub is accessible for the insertion and removal of the articles to be washed. The slidably opening Side .walls and cover do not require additional space when they are open and they are always in position on the housing. The washing machine can thus be employed in a more limited space and with less liability of loss or injury to parts of the housing than would'be the case with hinged or separable sides and cover. When the tub is in operation the housing may be entirely closed so that there is no chance for the escape of water or steam or for injury to the person or 1 ,eaaaea garments of persons about the machine or the articles being washed.

The tub may be started and stopped from the outside of the housing by turning a single handle and the wringer is mounted in a handy position and is driven by the motor which oscillates the tub. The housing is rigid and strong, presents a neat appearance and -may be readily moved from place to place.

Having described my invention, claim is 1. A housing ,for enclosing the tub and operating mechanism of a washing machine comprising a base formed of bars secured together at their ends to provide a substantiallyl'ectangular frame, a pair of end walls each of said end walls having a rectangular 'shaped bottom portion and a semi-circular top portion and having an inwardly turned flange along the edges thereof, a pair of strips carried by said end walls in spaced relation to the flanges to form therewith guideways, a pair of opposite vertical flexible side walls whose longitudinal edges are slidably supported in the guideways and adapted by the their flexibility to follow the circular path of the guideway when the side walls are lifted upwardly, a semi-cylindrical cover comprising a fixed ortion and a flexible portion whose longltudinal edges are slidably supported in the guideways, to permit removal of the flexible portion of the cover by pushing it downwardly and to either side.

what I 2. A housing for completely enclosing the tub and operating mechanism of awashing machine, comprising a base formed of bars secured together at their ends to provide a substantially rectangular frame, a pair of end walls carried by the frame and having inturned flanges to form corner posts and guides, a pair of strips carried by said end walls in spaced relation to the flanges to form therewith. guideways, a pair of opposite side walls whose longitudinal edges are slidably supported in the guideways, and a cover whose longitudinal edges are also slidably supported in the guide ways.

3. A washing machine having a housing with its longest axis in a vertical plane comprising two end walls each made from. a

single piece of sheet metalprovided with an inwardly extending flange around three sides thereof, and a pair of fixed side walls and a slidable curved top wall held in position by the flanges of the end walls; a tub journaled in bearings supported on the end walls and means-entirely within'the housing to oscillate the tub.

In testimony whereof I hereunto subscribed my name.

ADOLPH F. ANDERSON.
