WASHING MACHINE.

Application fi1ed May 20, 1920. Serial No. 382,825.

chine having a power driven oscillatory receptacle or clothes holder which when placed in action causes the clothes and contents of the receptacle to be sufiiciently agitated so that dirt and other foreign matter will be removed therefrom and the clothes thoroughly cleansed.

The primary object of my invention is to provide this type of washing machine with a. novel suspension construction or oscillatory support for the receptacle and'the-construction of either may be suchthat a desired movement may be imparted to the receptacle either by power from a suitable motor or hand operated mechanism.

A further object of my invention is to attain the above result by a simple, durable and inexpensive construction that will be hereinafter considered in its various forms and then claimed. 7

Reference will now be had to the drawings, wherein Figure 1 is a side elevation of the washing machine; I V

Fig. 2 is a similar view of a portion of the machine showing one of the equalizing members; v

Fig. 3 is a detail sectional view of a portion of the machine showing an end view of the equalizing member;

Figs. 4: to 8 inclusive diagrammatically illustrate the various forms of oscillatory supports for the closed receptacle of the machine;

Fig. 9 is an end view of a receptacle support;

Figs. lOyto 12 inclusive diagrammatically illustrate additional forms of suspension members, and

Figs. 13 to 16 inclusive are diagrammatic views of other suspension members that may be used in connection with the machine.

Reference will first be had to Figs. 1, 2 and 3, showing the washing machine as comprising opposed side frames 1 provided with Specification of Letters Patent. Pail gntgfl Jung casters 2 so that the machine may be conveniently moved from place to place, and these side frames may be made of structural steel and suitably connected, as at 3, so as to provide a substantial support for a receptacle or tub 4 arranged between the upper end of the side frames 1, said receptacle or tub having a detachable lid or cover 5 which permits of clothes or other matter being placed therein.

In the lower part of the machine is an opcrating compartmentti containing an electr c motor '7 provided with a plug so that it may be connected to an ordinary electric lighting circuit or any suitable source of electric lighting circuit or from a suitable switch on the machine. The electric motor electrical energy, and the operation of the 5 electric motor may be, controlled from the 7 has its armature shaft provided with a pul- V ley 9 for an endless belt 10 which is trained over a large pulley ll on a driven shaft 12 journaled in the frames 1, and in addition to the pulley 11 there is'a crank or cranks 13 suitably disposed on the driven shaft. The H machine may haveabelt tightening device 8 i and any suitable power transmission in lieu of the belt.

One of the frames 1 supports a bearing 14 for a conventional form of hand or power V The ,wringer I l thereto,through the bearing 14, by suitable 5 power transmission mechanism extending from the shaft 12 to the main wrlnger shaft 18, and a suitable stop, change speed or di rect and reverse drive mechanism, generally V designated 17, may be used. 7

The bottom of the receptacle or tub l has bearings 19 at its sides and adjacent its ends c for transverse rods 20 and the ends of these rods are supported by eyes 21 at the lower ends of suspension members 22. In some instances the side walls of the receptacle may be provided with studs or suitable bearings for the suspension members 22 or that said members may be of various lengths. These members may have the upper ends thereof pivotally held by the upper ends of the frames, as will hereinafter appear, but in Figs. 1 to 3 inclusive the upper ends of said suspension members are pivotally connected, as at 23, to the ends of equalizing members 21 which are pivoted intermediate theirends to hangers or brackets 25 carried by the top rails 26 of the frames 1. The equalizing members 24 will compensate more or less for any dimensional inaccuracies in the suspension members 22, but more especially insure an even and undilatory movement of the receptacle or tub 4 should the machine rest on an uneven floor. In other words, the equal izing members 124; permit of the receptacle having a pendulum movement irrespective of the angularity of the side frames of the machine.

One of thetransverse rods 20 is connected by a pitman or pitmen 27 to the crank or cranks 13 of the driven shaft 12 so that by the end connection with the receptacle or tub l it may be swung or oscillated between the frames 1.

Instead of suspending the receptacle or tub a from the upper ends of the frames 1,

either directly or indirectly, I may hold the receptacle 4% for an oscillatory movement by supports or links 28 pivotally connected to the lower portions of the frames 1 and the bottom of the receptacle, as shown in Fig. 1

to 9 inclusive. In Fig. 4- the oscillatory supports 8 are of equal length and comparatively short and may be three or four innumber; in Fig. 5 the supports are of greater length; in Figs. 6, 7 and 8 the supports at one end of the receptacle are of a greater length than at the opposite end, and in Fig. 9 an end support takes the form of an 1 member in contradistinction to the link form shown in Figs. 4: to 8 inclusive.

As brought out in Figs. 10 to 12inclusivc I may use link supports 29 of equal or varying lengths, one" or more, at each end of the receptacle or tub 4 with the lower ends of to the frames 1, instead of the equalizing -members 2 1 and this has been shown in Figs.

13 to 16 inclusive, where the suspension members 30 may be of various lengths, either of link form as shown in Figs. 13 and 15 and at one end of the receptacle in Fig. 16, while at the opposite end of the receptacle and as shown in Fig. 1d, the suspension member ma take the form of a single link 81 having a fork 32 at its lower end connected to the receptacle or tub 4c. In illustrating these various forms of suspension members or link supports it is my aim to point out that various suspension arrangements may be utilized between the frames 1 so that the receptacle or tub 4 may be oscillated in a tie sired manner, and consequently I do not care to confine my invention to any particular size, shape or arrangement of suspension members. My invention is also susceptible to such other changes as fall within the scope of the appended claims.

What I claim is '1. A washing machine comprising side frames, an oscillatory receptacle between said frames, independently supported equalizing members supported from said side frames, means having connection at the sides of said receptacle and at the ends of said equalizing members for supporting said rcceptacle so that it may be oscillated, and means at the lower ends of said frames adapted for operating the supporting means of said receptacle to impart movement thereto.

2. A washing machine as characterized in claiml, wherein saidreceptacle supporting means includes projecting connections at the sides of said receptacleadjacent the ends thereof, and suspension members carried by the ends of said equalizing members.

3. A washing machine comprising side frames. independent hangers intermediate the ends thereof, equalizing membershaving middle portions pivotallyconnected to said hangers, suspension rods at the ends of said equalizing members, a receptacle between said rods and supported thereby, a pitman connected to one of said rods for swinging said receptacle, and operating means for .sai d pitman.

In testimony whereof I aflix my signature in the presence of two witnesses.
