MACHINE.

` SPECIFIGATIONforming part of Letters Patent No. 736,410, dated August 18, 1,9048.

` Appnca'titntie september 12,1902. `smaila.123,093. cromati.)

invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to wliich it appertains to make and use the same.

This invention relates to washing machines; and it consists of the novel construc-V tion and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a vertical section through the washing-machine. Fig. 2 is a plan view of the washing-machine. Fig. 3 is a plan View ofthe clothes-agitator. Fig. tt is a side-view of one Aof the toothed segments.

Fig. 5 is a detail sectional view of the agita-` tor and its driving-wheel.V Fig. 6 is a detail view of the post K and vbearing 7c.

A is the washtub, supported on legs a. This tub is of any approved construction, and its sides and bottom are plain or corrugated,

as may be required. The tub isprovidedV with a lid B, which is hinged to it in any approved manner.

C is the agitator-shaft, which is journal-edV in a plate c, secured to the top of the tub; The plate c has openings c in it, and D represents antifriction-rollers arranged ini the openings c and journaled on pins d,'inserted in the said plate.

E is a sleeve which is secured on the lower part of the shaft C by a pin e and provided with a iiangef at itslower part and longitudinal projecting ribs f' on its sides.

F is the agitator, which` consists of a plate provided with arms g .for engaging with the clothes. The agitator fits loosely over the sleeve E and normally rests on its flange f below the pin e, and it is provided with notches which engage loosely with the ribs f. In this manner thejagitator is constrained to revolve with the shaft C, but is free to tip or tilt to a limited extent in any direction.

G is a toothed wheel provided with a sleeve h, having a flange h at its top. The wheel and sleeve are rigidly secured on the agitator-shaft C, and the wheel runs on the antifriction-rollers D.

a a I H represents arms arranged equidistant y Beitknown that I, MILES .T LAWLER, a citi- `zen of the United States, residing atParnell,

in the county of Iowa and State of Iowa, have from each other between the flange h and the body of the toothed wheel G. Weights t are secu red on these arms and may be either fixed or removable. When re movable,lighter or heavier weights may be substituted for them. These weights balance each other, being arranged at equal distances apart.

I is a screw-threaded cap which is adjustable upon the screw-threaded upper end portion of the shaft C. This cap has a conical bearing j, which engages with a correspond` ing bearing in an arm or bracket J, which is secured to the lid of the tub, so that the shaft C is prevented from rising.

K is acircularpost or pin which is secured to the lid of the tub parallel with the shaft C. A bearing 7o is formed at the top of the post K and is provided with a removable cap 7.o'.

L is a bearing secured to the lid of the tub 4 a short distance from the bearing 7a.

Mis the operating-shaft, which is journaled in the bearings 7o and L, and m is a ily-wheel secured'on the shaftM and provided with an operating-handle m. r

O and P are two toothed segments secured upon the shaft M and arranged upon oppositel sides of the bearing 7c. The teeth of each segment are arranged opposite the toothless portion of the other segment, eachsegment having teeth on one half only of its periphery.

R is a toothed Wheel which is journaled on the `post or pin K and which =is engaged by the toothed wheels O and P alternately as the shaft M is revolved.

Sis a toothed wheel which is secured to the wheel R and which also is journaled on the post or shaft K and which gears into the toothed wheel G on the agitator-shaft. The wheel S is preferably smaller in diameter than the vwheel G.

When the operating-shaft is revolved continuously in one direction, the agitator is oscillated inside the tub and Washes the clothes placed in the tub in avery effective manner.

The weights are made removable in any approved manner-as, for instance, by having slots like the weights of a weighing-.machine. These weights are slid upon the inclined arms H to different distances from the center of the shaft, so as to balance the wheel G in its normal position on the rollers. The weights also counteract the upward pressure of the clothes in the tub. When the machine is in operation, the clothesfrequently collect under the agitator, and if the weights were not used or if they were too light the agitator when bearing against the pin e would force the sleeve E upward against the lid of the tub or would press the bearing y hard against the bearing in the end of the bracket J, and thereby make the machine very hard to turn.

I do not herein claim the driving-gear shown and described in this application, as the 2. The combination, with a tub provided with a lid, and an agitator-shaft journaled in the lid; of a sleeve secured on the lower part of the said shaft and provided with stops, an agitator revolving with the said sleeve and movable vertically between the said stops, a driving-wheel secured on the upper part of the said shaft, and removable weights carried by the said wheel and operating to counteract the upward pressure of the clothes in the tub, substantially as set forth.

3. The combination, with a tub provided with a lid, and an agitator-shaft journaled in the lid; of an agitator carried by the lower part of the said shaft, a toothed wheel secured on the upper part of the said shaft and provided with a sleeve on its upper side havv ing a ange and equidistant bars extending between the said flange and the body of the said wheel, and weights on the said bars, substantially as set forth.

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

MILES J. LAWLER.
