Specification of Letters Patent.
Patented May 12, 1908.-
Application filed October 3, 1906. Serial No. 337,180.
To all whom it may concern:
Be it known that hlATHIAS JOHN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Bearings; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention consists in what is herein shown, described and claimed its object being to provide simple, economical and durable bearings especially designed for the shaft-sleeves of vertically adjustable rubboards in washing-machines, said bearings being easy running and not liable to get out of order nor to permit the exudation therefrom of lubricating material into the tubs in which said rub-boards have their rotary movement.
Figure 1 of the accompanying drawings represents a central Vertical section of a vertically adjustable rotary rub-board washing machine embodying my improvements, the view being indicated by line 11 in Fig. 2, which Fig. 2, represents a plan view of a fragment of the machine partly in horizontal section on the plane indicated by line 22 in Fig. 1, and Fig. 3, a partly sectional view of a detail of the machine showing the substitution of a gear-wheel for a crank on the sleeve in which the rub-board shaft is vertically adjustable.
Referring by letter to the drawings, A indicates the tub of a washing-machine and B the cover for same. The cover is provided with a central aperture in register with the bore of a boss C having an annular base flange b fastened on said cover, by screws or other suitable means. The upper end of the boss is in beveled groundjoint engagement with the underside of an outer annular flange c of a sleeve D, which sleeve engages said boss and has the bore thereof engaged by a shaft E having a bottom flange (Z in connection with the rub-board F of the machine, the shaft and sleeve-bore being preferably angular. Encircling the sleeve, and screw threaded on the boss C, is a cap G over the sleeve-flange c, a set-screw (1 being employed in connection with the cap to fasten the same in place. The rub-board shaft is held by a set-screwfin vertically adjustable connection with the sleeve thereon, and the upper end of said sleeve has angular :fit in a corresponding aperture of the hub of a crank II or gearwheel I, either of which serve as a means of applying the power necessary for the rotation of the aforesaid sleeve, shaft and rubboard, said sleeve being otherwise cylindrical. To facilitate the vertical adjustment of the rub-board, the shaft of same is provided with a ring J or other suitable handle at its upper end. To permit of lubricant being readily supplied to the bearing for the sleeve D, the cap G is notched adjacent to said sleeve to provide a port g, as shown in Fig. 1.
The bottom of the tub and the opposing face of the rub-board are corrugated, as is customary in the art. Provision for vertical adjustment of the rub-board, to accommodate the same to more or less thickness of material in the tub to be washed is also common in the art. As some materials are preferably washed by agitation rather than by rubbing, and with other material it is preferable to have an agitation and rubbing of the same during a washing operation, the rubboard of the machine herein shown is provided with inclined wedging-sockets for the engagement of detachable tapered agitating pins ii of any sufficient number and arrangement.
I claim:
1. The combination of a boss having an attaching base, a partly angular but otherwise cylindrical rotary sleeve engaging the boss and provided with an outer annular flange in ground-joint engagement with the adjacent end of said boss, a cap encircling the sleeve over the flange of same and screwthreaded on the aforesaid boss, a shaft vertically adjustable in said sleeve longitudinally of the same with which it has rotation, means for holding the shaft in adjusted position, and a power-transmission device fitted on the angular portion of the aforesaid sleeve exposed beyond said cap.
2. The combination of a boss having an attaching base, a partly angular but otherwise cylindrical rotary sleeve engaging the boss and provided with an outer annular flange in grouml-joint engagement with the adjacent edge of said boss, a cap encircling the sleeve over the flange of same and screwthreaded on the aforesaid boss, a set-screw in connection with the cap to provide for fastenmg the same 1n place, a shaft ad ustable in said sleeve longltudmally of the same with which it has rotation, means for holding the the county of Milwaukee and State of Wisshaft in adjusted position, and a powerconsin in the presence of two Witnesses.
transmission device fitted on the angular portion of the aforesaid sleeve exposed be- MATHIAS JOHN 5 yond said cap. Witnesses:
In testimony that I claim the foregoing I GEO. W. YOUNG,
have hereunto set my hand at Milwaukee in GEORGE FELBER.
