ing Machines, of which the following is a specification.

My invention relates to improvements in washing machines, the object of the invention being to provide a washing machine in which the clothes arethoroughly agitated through the medium of improvedmechanical-means, which latter are easily operated so that the minimum of power is necessary to operate the washing machine.

A further object is to provide an improved washing machine in which the clothes are supported in a swinging basket and-provide in connection with the basket, an-agitatorvmounted in the cover of the washer and which basket and agitator are simultaneously operated by improved mechanicahmeans so that the clothes are swung in the basket and are agitated in the basket, so that they are thoroughly and quickly washed asthey are exposed inall parts to -the action of the soapy water-in the 'machine.

A further object ist-o provide a washing machine of this character in-which the cover may be raised or removed to. allow the clothes to be inserted or removed, and provide in connection with the machine. improved mechanical operating means which are removable from one side of the machine.

With these and other objects in view, the invention consists incertain novel features of construction and combinations-and arrangementslofparts as will be mercifully claims.

In'the accompanying drawingsz Figui-e 1 is a view'in side. elevation illustijati-ng -my improvements showingthe. fly. wheel broken away to illustrate parts behind the same. Fig. 2 is a view in longitudinal-section through the center of-the-ma'chine. Fig. 3 is-aview in transverse section'through the center of the machine with the mechanical drivingmechanism removed from the side oft-he machine. Fig- 4 is aplanview-of Fig. 3. 'Fig. 5 is an enlarged view in cross section showing the mounting of one of the segments. 'Fig. 6 is an'enlarged view in elevation of the mechanical operating means detached from the washing machine. Fig. 7-is a View of the supporting frame for the mechanical operating mechanism. Fig. 8 1s a perspective View of the block 35, andF-ig. 9 1s a view inelevation of the casting-42.

1 represents a rectangular box or receptacle supported upon legs 2 and provided with a drain opening 3 normally closed by a plug 4. The box or reoeptaclel is normall closed by a cover 5 which is connected to the box or receptacle at one-end-by -means 'of separablerhinges 6, and these-hinges-have shoulders 7 which allow the coverto be sup.-

ported in an uprightposition or removed entirely,fro1n the receptacle-as'desired. The

opposite end of the cover 5 is, provided with apivoted handle catch 8 which is removable beneath akeeper 9 on the receptacle, so that the cover may-be secured in closed position.

Pivoted hangers 10are secured to thesides of the receptacle 1|near its top and these hangers 10 have segmental bearings 11 in their-lower ends in which trunnions 12 on the sides of the basket-13am normally positioned. This basket 13, may of course be variously made, but is preferably of-metal, and perforated to; allow the soapy water to flow freelythrough-the same. Fourhangers 10 are preferably provided, two at each side of the receptacle, with the hangerslocated adjacent the ends of the basket, and

to the center of the basket at both sides, brackets 14 are fixed. :The intermediate portions of'these brackets constitute journals 15 which-are mounted to turn in recesses 16 in the side walls of receptaclel. These recesses 15 have metal linings 17 to allow .the journals 15 to freely turn, and the upper portions of the brackets constitute-toothed -segments 18 which-are connected with the hereinafter described and pointed out in the outer ends of the journals. 15 and are located outside of the receptacle 1. These segmerits-18 normally-mesh with pinions 19 on the respective ends of a shaft 20. This shaft '20 is-supported in bracketsfzl. on the cover 5, andto-the shaft 20,.a beveled gear 22 is secured and meshes with a horizontally positioned beveled gear 23 supported in a bracket 24 secured to the cover 5 at the center thereof. This gear 23 is fixed toa vertical shaft 25 which projects through the cover and is provided with a rotary agitator 26 extending into the basket 13. This agitator 26 may be-made. in various forms, but is preferably of, the pin or finger type, and ithas vertical movement-on theshaft to comyes pensate for the diderent quantities of clothing in the basket. While it is permitted a vertical movement on the shaft, it is com-- polled to turn with the shaft by reason of keys 27 on the shaft, and the shaft receiving opening in the agitator 26 is of such a shape as to receive the keys and allow the agitator to slide on the shaft without independent rotary movement.

My improved mechanical means for moving the basket and the agitator is removably connected to one side of the receptacle, and is supported upon a frame 28. This frame 28, as seen most clearly in Fig. 7, is provided with two bars 29 which are adapted to be positioned in recessed brackets 30 secured to receptacle 1. The frame 28 at its opposite end is formed with an opening 31, and is adapted to'receive a fixed pin 32 on a plate '33 secured to the side of receptacle 1. A pivoted arm 34 is connected to the plate 33, and is adapted to be swung over the frame 28 to prevent the same from moving off of pin 32, thus holding the frame in operative position-on the side of the machine. "When it is desired to remove the same, it is simply necessary to swing the arm 34 to one side, move the frame laterally at this end, and then move it longitudinally to draw the bars 29 out of the recessed brackets 30.

A block 35 is pivotally supported between its ends on a pin 36 secured to frame 28. This block 35 is formed with a longitudinal groove 37 in its inner face which receives a flange 38 on the segment 18 of one bracket 14, so that while the bracket 14 is free to move vertically to allow the basket to move into and out of the receptacle, when it is moved into the receptacle, the flange 18 will be positioned in the groove 37, and the segment 18 will be compelled to move with block 35. This block 35 has a V-shaped recess 39 in its upper end to guide the flange 38 into groove 37, so that the parts readily find their normal positions. The upper and lower ends of block 35 are connected by links 40 with arms 41 integral with a casting 42. This casting 42 is pivotally connected to frame 28 by means of a pin 43, and the said casting is formed with integral sleeves 44 and 45 which are positioned at right angles to each other, and an operating lever 4'5 is adapted to be positioned in either of these sleeves as desired. The casting 42 is connected by a link 47 with a crank pin 48 on a gear wheel 49, the latter having rotary mounting on a journal pin 50 secured to frame 28. This gear 49 meshes with a pinion 51 fixed to a short shaft 52 supported in a bearing 53 on frame 28, and a large wheel 54 is secured on the shaft 52. wheel 54 may constitute either a flywheel or a pulley, and it vmay receive power or may operate as a balance mechanism as desired.

In operation, when an oscillating move- This orena? ment is imparted to the casting 45 by means of the lever 46, such oscillating movement will be imparted to block 3-5 through the medium of links 40 and the segments 18 will be caused to oscillate, swinging the basket 13 and at the same time causing shaft 20 to turn first in one direction and then in the other to move the rotary agitator 26. This ,movement of the rotary agitator will, of

course, be first in one direction and then in the other, and the degree of such turning movement is controlled by the relative sizes of the gears. The movement of casting 42, through the medium of link 47, gear 49, and pinion 51 causes the wheel 54 to turn, and the momentum of this wheel operates as a balance to overcome any dead. centers and assists in compelling an easy running movement to the machine. Furthermore, the weight of the clothes in the basket as the basket moves downward from either of its extreme positions gives a sufficient momentum to start the basket upwardly in the opposite direction. It will be noted that the basket moves longitudinally and vertically through the arc of a circle permitted by the hangers 10. The washing, of course, is to be accomplished by soapy water or other washing preparations, and after the washing operation, the clothes are to be passed through any suitable form of wringer and a bar 55 is secured on one end of the receptacle 1 and forms a convenient attaching means for a Wringer.

It will be noted that the basket can be readily lifted out of the receptacle without interfering with the operating means, and the operating means may be readily detached vfrom the side of the receptacle without interfering with the basket.

By providing the two sleeves 44 and 45 on casting 42, the lever 46 may be positioned either vertically or horizontally, so that the machine may be operated while the operator is either in a standing or sitting posture.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invem tion, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scoipe of the appended claims.

aving thus described my invention, what l claim as new and desire to secure by Lettors Patent is:

1. A. washing machine comprising a receptacle, pivoted hangers in the receptacle, a basket removably supported in the free ends of the hangers, a cover on the receptacle,
