new and useful Improvements in Washing- Machines, of which the following is a specification.

This invention relates to an improvement in washing machines, and has for one of its objects to provide a machine having parts so arranged that the vertical shaft and its dolly may have its required reciprocatory rotation with greater facility than,l ordinary. Another object is to provide 'convenient means for a movement o f the machine fromy one part of a room to another, whether the tub is filled or empty. Other objects relate to simplicity in construction so that the parts may be economically constructed and will be durable. The invention includes an axle provided with wheels arranged below the tub, vadapted to rotate during operation, as balance-wheels, or may be used-V as a truck upon which the entire weight of the tub and contents may be supported, 'both of these features being found to be of great advantage. i

With the foregoing objects in view, the invention presents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the drawings, it being understood that size, form, proportion and minor details may be changed without departing from the invention, the scope of the invention being determined by the appended claims.

In the drawing, Figure 1 is .a view in longitudinal section of a washing machine embodying my invention, one of the guides for a segmental arm being also in section. Fig. 2 is a plan View of the machine. Fig. 3 is a side view showing the machine disposed in an inclined position and supported, in part, upon wheels. Fig. 4 is a sectional detail showing the alining gear-wheel splined on the vertical shaft. Fig. 5 is a rear side view i of the machine. Fig. 6 shows one of the aXle-bearin arms employed. Fig. 7 is a detail showing a locking means for an axlebearing arm.

Iprovide a tub 8 of any suitable proportion, the conventional legs and lid therefor being indicated, respectively, at 9 and 10. Agitating devices are employed conslstlng,

in part, of an alining gear-wheel 11 which, as best shown in Fig. 1, has a downwardly projecting, tubular stem a with a terminal annular flange b, the aperture c for the wheel 11 and its stem preferably being angular in cross-section for receiving the vertical spindle or dasher-shaft 12, upon the lower` end of the latter being slidably mounted, the conventional, non-rotatable dolly 13, the stem a having bearings in the pair of tubular segments 14 which are disposed between the lower end of the wheel ll and the liange b, the segments beingt provided between their ends with flanges l which are ysuitably secured to the lower side of the lid 10.

The parts thus described are of simple construction and may be conveniently assembled, and if a reciprocatory rotary motion is imparted to the gear wheel 1l, the shaft and dolly will have a corresponding movement for agitating the contents of the tub, the shaft 12, on account of its bearings being normally maintained in a vertical position, and being adaptedto have slidable movements in said bearings, so that if desired by an operator, the dolly may suitably engage the fabrics a: (F ig. 1.), this v being of advantage since the contents of the tub, as-to volume, may not be uniform at all times.

The wheel 11 is actuated by means of rack-bar 15 movable by the hand-lever 16, the latter having a pivotal connection therewith, as indicated at 17. The hand-lever 16 is mounted pivotally between its ends, as indicated at 18, upon a bracket 19 which is suitably secured to theside of the tub.

Numeral 20 indicates a hanger which is secured to the bottom of the tub. Its lower end has a' wrist-pin e mounted therein to provide bearings for a toothed gear 21, the latter being provided with a pivot-pin 22 upon which is mounted an actuating-rod 23, the opposite end of said rod having a pivotal connection, as indicated at 24, upon the lower end of the lever 16; and as thus described, since the toothed ear 21 will be rotated during operation an will perform the functions of a balance wheel, it is a material advantage as an aid in operating the handlever, while effecting reciprocatory rotation of the shaft 10, for agitatingthe contentsof the tub.

mentums required,and therefore a combined vehicle` and impulse-member 25 is provided, consisting of a pair of wheels 26 rlgidly mounted on an axle 27, the latter having a pinion 28 mounted thereon.

N umerals 29 indicate a pair of links havin pivotal mountings 30, fory their upper en s, preferably, upon the legs 9, each linkl at its inner end being provided with a coly tum, said means also being operative forlar 3l, and it will ybe understood that vthe pair of collars 31' provide bearings. for the ends of the axle 27. 1

' Any suitable means may be provided for moving the pinion 28 into engagement with the rotatabletoothed gear 21 so that the wheels 26"m-ay provide additional momenmay have a swinging movement in one direction'to cause the teeth of the pinion 28 to engage the toothed gear 21,l whereby the greater degree of momentum will be prothe toothed gear 21 is disposed inline with vided for actuating the shaft 12.

Numeral 321 indicates a foot-rail which connects the outer ends of the arms 32, and in order that the pinion 28 maybe maintained in engagement with the toothed gear 21 each arm 32 is provided with anotch 35 for receivingthe lower end of a pawl-rod .36, said rods 36 being provided with springs 37 tending to normally press them in a di'- rection of the arms 32, the upper ends of the pawl-rods, as best shown in Figs. 1 and 5, being pivotally connected with the handles 38 which are pivotally 'mounted at their inner ends as indicated at 39, whereby the rods 36 may bemoved upwardly, against the force of the springs 37, the links 29 and wheels 26 thereupon having\a downwardswing movement by action of gravity, the arms 32 moving in an arc of a circle, the center of which is .a pivotal mounting 3() of a link 29. An operator, by a downward pressure on the foot-rail 34: may cause engagement of the teeth of the `pinion 28 with the toothed gear 21, and the parts mentioned are arranged for convenient operation.

The arms 32 are each'provided with a second notch 40, and the actuating-rod 23, at its outer end is provided with a handle 11, and

- the machlne may bev readily elevated from the floor with its weight supported `by the wheels, the operator, for this purpose using the hand-lever 16 or handle 4:1 for elevating the rear side of thev tub to permit the wheels stantially a vertical position, the pawls will.

engage in the notches 40, which'operates to maintain the links in fixed relation with the longitudinal axis of the tub, and the machine may then be moved about a room, member 25 operating as a vehicle for this purpose,c

this feature obviously being a great' advanta e. l

umeral 42 indicates a guide provided for lthe top of the lid which, during fope'ration,

maintains the rack-bar inengagement with f the gear wheel 1l. The rack-bar, therefore,

may be swung to the position shown vin Fig. l I 3, 1f desired, when using the lever 16 or hanl dle 41 for moving the machine; and for actu'- ating the `shaft 12, the rack-bar may be swung forwardly to be disposedas shown in l Fi 2. l

`hen' only a limited degree of momentum is required for actuation of the shaft 12, the pawls may be disengaged from the notches and the wheels and legs 9 will rest upon the loor, and since the pinion. 28 will be disengaged from thetoothed gear 21, the'latter, during operation, will rotate as a balance wheel. a V
