WASHING MACHINE.

Application filed September 7, 1923. Serial No. 661,503. 7

- The invention is primarily devised as a means for lubricating the vertical spindle of a rotary washing machine, and 1s em' bodied in a construction which permits the lubrieantto be applied at the lower end of the spindle and automatically fed upwardly 7 thereof so as to lubricate the said spindle throughout its entire area of contact with the fixed tubular post in which it is mounted to rotate.

" The invention also embraces the loose arrangement of a sleeve upon the said fixed post, to permit rotation of thelatter when engaged by the fabrics being washed and prevent destruction of such fabrics under strains imposed by the dolly.

These and other details of construction will be hereinafter described, and the nov-' elty of the invention will be theap ended claim. In t e drawing:

pointed out in Figure 1 is a vertical sectional view.

not shown, at its upper end. Thespindle 11 is guided and supported for rotation in an elongated tubular post 12, which latter by means of clamping nuts 13 and 14 is securely positioned'in the central bore of the bottom 10 of the tub. Gaskets or washers 15 and 15' through which the said st is passed are applied at the opposite sidgs of the botv tom 10, and when the nuts 13 and 14 are screwed in position, a leak-proof connection is made. At the same time the tubular post 12 is rigidly secured in operative position.

A cap nut 16 is threaded upon the upper end of the post 12, a disc 17 fixed upon the upper end of the spindle 12 resting upon the said cap nut, and supporting the spindle in vertical position. The disc 17 is provided upon its upper face with an eccentrlcally arranged pin 18 which latter is designed to receive thereon the .usual agitating dolly, and

to impart movement thereto in the rotation.

of the spindle. A fly wheel 19 is mounted on the'lower end of the spindle 11 at a point immediately below the bottom 10 of-the tub. The extreme lower end of the said' spindle is connected by reducing gears to the shaft of an electric motor, which may be conveniently mounted upon the frame of the washing machine, and arranged so as to give movements of continuous rotation to the spindle 11.

Near its opposite ends the spindle 11 is provided with circumferential grooves 20 and'20 for the reception-of packing rings 21, inter-positioned between the opposite ends of the tubular post 12 and the clearance at the base of the threadedportions of the nuts 16 and 14. An elongated groove 22 extendlng circumf'erentially of the spindle 11, connects the annular rooves 20 and 20', such elongated, groove being designed to effect vertical movement of lubricant applied to the spindle 11 at the lower end of the groove 22, so as to efficiently lubricate the surface of the said spindle at the points of its contact with the tubular post 12. The packing rings 21, before referred to limit the movement of the lubricant to the area desired.

' One side of the nut 14 at the under side of the bottom 10 of the'tub is bored for the reception of an. oil cap or grease cup 23, containing any suitable lubricant. The lower end of the post 12 is provided with an opening in alignment with the oil cap or grease cup so that the lubricant may flow from the latter into contact with the surface of the rotating spindle exposed thereto. The best results are secured by forcing the feed of the lubricant, and it will be apparent that thorough lubrication of the spindle is sev cured. The assembly of the parts is such that thewater in the tub, although it may rise to the cap 16, cannot reach the interior of the tubular post 12, the packing ring 21 at the upper end of the spindle serving the double purpose of retaining the oil and excluding the water.

The under side of the cap nut 16 and the upper side of the nut 13 are provided with concentric seats 24 and 25 for the reception of a tubular sleeve 26 adapted to have free rotation about the fixed post 12. The purpose of this construction is to prevent strain upon the fabrics bein washed, due to the pull thereon by the agitating dolly. In the absence of such a freely sleeve, the fabrics would cling. to the fixed post and be torn in the movements of the dolly. Modification in the arrangement of. the partsmay be made without, epa rtingfrom the spirit of my invention. J

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States; is:

In a washing machine, a tubular post fixed in the bottom of the tub thereof, a spindle mounted for rotation in the said post, a recessed nut upon the post bearing against the bottom of the tub, recessed cap nut threaded upon the upper end of the post, and a freely rotating sleeve surrounding the said post and confined between andseated in the recesses in the said nuts, such sleeve rotatable by the pull of the fabrics thereon during the operation of washing.

In testimony whereof, I have signed my name at Milwaukee, this 31st day of August,

HENRY JOSEPH.
