Application filed .J'uly .:1 1, 191.0. Seria1.No.'57l,-'388.

This invention relates to washing machines and has .for its object to provide means for operating a rotatable agitating head disposed within the clothes tub or vat Another object of the invention resides in the application of a clock mechanism to a washing machine for operating the clothes agitator, said mechanism being geared to a crank shaft, the crank of which is connected by means of a link rod to the upper end of an agitator shaft disposed through the lid of the tub to impart an oscillatory ro tary movement to the agitator.

lVith these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinaften fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the machine embodying my improvements; Fig. 2 is a top plan view thereof; Fig. 3 is a section taken on the line 33 of Fig. 1; and Fig. 4 is a detail fragmentary perspective view of the operating and agitator rods and the connection therebetween.

Referring more particularly to the drawings 5 indicates a clothes tub or vat which is mounted upon the vertical supports 6. The tub and its supports are preferably formed from galvanized iron or other sheet metal. A lateral flange 7 is formed upon the upper end of the body of the tub and extends beyond one side thereof. The ends of this flange are turned up or vertically disposed as shown at 8 and between these vertical ends an extension 9 formed upon one side of the hinged cover 10 of the tub is adapted to be received. The end of this extension is formed with a vertical flange 11 which when the cover is in position upon the tub extends to the upper end of the vertical end portions 8 of the flange 7. The flange 11 is adapted to support a clothes wringer. The cover 10 is hinged as shown at 12 and through the center thereof the shaft '13 secured at its lower end to the agitator head .14., extends. A sleeve 15 is centrally secured to the lidor'cover to provide a bearing for said shaft.

A clock mechanism '16 is secured in any desired manner 'to the bottom of the tub or va't-o. Thiscl'ock mechanism maybe of'any well known construction and -to the spring shaft thereof acrank 17is attached by means of which the spring may be wound. With one of the gears 16 of the clock mechanism, agear ISsecured tothe-lower'end of the vertically disposed shaft 19 meshes. While these gears may be of any desired form, I preferably utilize the well known beveled gear. The shaft 19 is mounted in bearings 20 secured to the side of the tub or vat. The upper end of this shaft is formed with a crank shaft 21 upon which a sleeve 22 is loosely mounted. Between a pair of lugs which project from one side of the sleeve a connecting rod 23 is pivoted and extends through an opening formed in the end of the angularly disposed upper end 14 of the agitator shaft 13.

In the operation of the machine, the clock work mechanism actuating spring is first wound, and the hook 24 arranged on one of the tub supports and engaged with the wind ing crank, released so as to permit the spring to unwind. Through the gear train rotation is imparted to the vertically disposed shaft 19 which through the medium of the connecting rod 23 imparts an oscillat-ory rotary movement of the agitating head. The rotation of the agitating head is through an arc of substantially 90. In this manner the contents of the tub will be thoroughly agitated and moved through the saponified water contained therein. The dirt contained in the clothes may thus be easily and quickly removed without subjecting them to undue wear. hen it is desired to remove the clothes from the tub, the lid or cover 10 is raised and the connecting rod 23 moved upwardly in the end of the link plate 22. After the clothes have been removed and the cover is again lowered, the wringer may be attached to the flange 12 on the end thereof and the water wrung from the clothes.

From the foregoing it will be seen that I have produced a washing machine and operating means therefor, which is very simple in construction and of great efliciency in practical operation. The cost of manufacture is extremely small owing to the small number of parts employed in the construction of the device. This also eliminates the necessity for repairs. As the tub and its supports are constructed from sheet metal, preferably galvanized iron, it will be obvious that the greatest possible durability is thus obtained without increasing to any material extent its cost of construction.

Having thus described the invention what is claimed is The herein described washing machine operating mechanism comprising in combination with a vertical shaft mounted for oscillation and having a crank arm at its upper end, a bearing for the said shaft supporting the same, a vertical operating shaft having a crank at its upper end provided with a vertical crank pin, a bearing for said operating Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

shaft, a sleeve on the crank pin and provided on one side with lugs, a pitman having one end pivotally connected between the said lugs, the pivotal axis of the pitman being at right angles to the crank pin and operating shaft, the opposite end of the pitman being downturned and detachably engaged With an opening in the crank arm of the first mentioned shaft, a motor, and gearing connecting the motor to the operating shaft.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
