a of which the machine can be operated at a minimum cost, and accomplish the desired results in a quick and efficient manner.

In carrying out the invention I provide the agitator with a plurality of angularly shaped to pivoted blades which are automatically rocked incident to the oscillation of the agitator, thereby promoting the circulation of water, directing it upwardly and through the clothes, and also turning the clothes over is in the machine at more frequent intervals.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the

invention residing in the construction, combination and arrangement of parts as claimed. In the drawings forming part of this application like numerals of reference indicate similar parts in the several views, and where- 1n: 7

Before entering into a detailed description of what is herein illustrated, I desire to have it understood that the machine forming the subject matter of the present invention can be constructed from any suitable material, and also vary in size and design without departing from the inventive idea.

The machine essentially includes a casing 10 preferably mounted upon casters 11 so that the machine can be conveniently moved from place to place. The casing is provided with spaced upper and

lower bottoms

12 and 13 respectively, and the space between these bottoms define a compartment for the transmission mechanism to be hereinafter described. The bottom 12 is formed with a marginal flange 14, while movably supported upon this bottom is the agitator as clearly illustrated in Figure 1.

The agitator is in the nature of a shallow receptacle including a bottom 15 and a vertical wall 16, while rising from the bottom 15 is a centrally located hub-like portion 17. Pivoted between the vertical wall 16 and the hub-like portion 17 are angular shaped blades indicated generally at 18, and while any number of these blades may be employed in a single machine, they are equidistantly spaced apart as clearly illustrated in Figure 2. Furthermore, the angularity or cross sectional configuration of each blade may vary without departing from the inventive idea, but these blades are preferably of substantially V-shaped formation in cross section as clearly illustrated in Figure 4, and the outer edges of the respective branches of each blade are preferably curved outwardly as indicated at 19.

As hereinabove stated these blades are freely pivoted, and are adapted to be automatically tilted incident to the oscillatory movement of the agitator in its entirety, and consequently during the operation of the machine, these blades shift from the position shown by full lines in Figure 4 to the dotted line position illustrated in the same figure, and in this manner the circulation of the water in the machine is materially promoted. In other words the water is not only circulated and agitated in all directions, but particularly forced in an upward direction by reason of the configuration of the blades, and thereby forced through the clothes. By the construction and arrangement of the blades and the fact that they continuously tilt from one side to the other, incident to the oscillatory movement of the agitator in its entirety, the clothes are also turned overat more frequent intervals, than in machines of the class in question, with which I am familiar.

bearing 22 The shaft however includes a cylindrical portion 21 which operates in a suitable boss or secured to the bottom 12 of the agitator.

shaft 18 bored to receive the power driven shaft 23, the latter having associated therewith the member 24 of a suitable clutch. The cooperating member 25 of the clutch is slid ably mounted upon the cylindrical portion of the agitator shaft as illustrated in Figure 1, and is moved into and out'of engagement with the clutch member 24 by means of a lever 26 which is fulcrumed atan appropriate point in its length as at 27. This lever moves through a slot 28 formed in the casing 10 and is connected by means of a link 29 with a manipulating handle 30. The clutch is held in either of its given positions by a suitable pawl and ratchet construction associated with the handle 30 as illustrated in Figure 1.

Located within the casing 10 beneath the bottom 12 is a housing indicated generally at 31 for the transmission mechanism, and this mechanism/includes a horizontally disposed gear32 which meshes with a worm gear 33 forming part of a shaft 34 which is,

rotated by a motor 35 through the instrumentality of a belt 36 as clearly illustrated in Figure 3. Arranged above the gear 32 and associated wlth the shaft 37 are

eccentrics

38 and 39 respectively and these are connected with the

arms

40 and 41 respectively which project laterally from the motor driven shaft 23 as clearly shown in Figure 7. R0- tated from one end of the shaft 34 is a vertical shaft 42 which may be utilized to operate.

a wringer or the like. The construction and arrangement of parts not only equalizes load noises, but results in the construction of a machine of the class in question which can be operated with a minimum of power and expense', and employing a minimum number of parts.

In practice, the operation of the agitator can be quickly and conveniently controlled through the clutch mechanism above described. and whenthe agitator is oscillated from the power driven shaft 23, the angular shaped blades 18 are rocked in reverse directionsand thereby direct the water upwardly through the clothes and keeps the latter constantly in motion, turning the clothes over at frequent intervals.

While it is believed that from the fore going description the nature and advantages of the invention will be readily understood,

I desire to have it known that I do not limit myself to what is herein shown and described, andthat such changes may be re- This cylindrical portion of the pivoted between -a casing, a receptacle-like agitator supported therein, means for oscillating the agitator, and a plurality of horizontally disposed blades angular in cross section, freely pivoted within the receptacle and adapted to be automatically rocked incident to the oscillatory movement of the receptacle.
