WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 501,063, dated July 11, 1893.

Application filed September 26,1892. Serial No. 446,871. (No model.)

To all whom it may concern:

Be it known that We, JOHN A. GLIOK, VAN. M. HEIM, and ADAM E. HAFER, citizens of the United States; residing at Reading, in the county of Berks,State of Pennsylvania, have. invented certain Improvements in Washing- Machines, of which the following is a specification.

This invention relates to that class of washing machines in which an oscillating rubber is employed, and it consists in animproved mechanism for operating said rubber, the main objects of which are: first to permit the tub to be closed perfectly tight when in operation; second to impart a considerable swing to the rubber with a minimum expenditure of power; third to enable the rubber to be easily operated with the tub cover in place no matter What is its position in the tub and at the same time to allow it to be readily removed therefrom. These objects we attain by means of a simple and convenient arrangement of parts which is fully described in connection with the accompanying drawings and the novel features of which are specifically pointed out in the claim.

Figure 1 is a central cross-section of a mechanism involving our invention. Fig. 2 is a sectional view on the line X X of Fig. 1. Fig. 3 isa partial outside view similar to Fig. 2 showing the rubber and operating mechanism in a different position. 4

A represents the tub which is supported upon legs A. The curved bottom is provided with a removable wash board B formed of cross slats b secured to a flexible base and held in place in the tub as usual. The tub is extended to form a convenient receptacle A and means for attaching a clothes wringer.

0 represents the oscillating rubber having trunnions c which enter vertical slots or bearings a in the side of the tub, these slots permitting the rubber to assume different heights in the tub while confining the trunnions upon which it rocks in the operation of washing. The rubber is provided with a central postD formed with alongitudinal slotd which is open at the top.

The rubber is operated by means of a double crank shaft E the central bar of which connecting the inner crank-arms e e engages the slotted post D, while the shaft journals e rest in hearings or a formed on the top edge of each side of the tub and an outside crank arm E on either side engages the slot g of an operating lever G. The latter is pivoted at its lower end to a fixed point g of the tub, below the bearing a. The crank pin which engages the operating lever is provided with an antifriction roller f which rides within the slot g, and a flanged rollerfin like manner rolls within the slot d of the rubber post, thus insuring the easy working of the mechanism. The flanges of the roller f serve to also maintain the post in central position upon the shaft, thus preventing the rubber from tilting sidewise.

The cover H of the tub is made perfectly tight. It is preferably hinged to one end of the tub as shown at h, is arched suffici'ently to clear the post D of therubberin its highest position and fits closely upon the top edge of the tub, being merely recessed at h to form the upper half of the bearing for the journals e of the crank shaft, which latter is thus held firmly in place when the coveris closed. The levers G are extended toward each other and are united in a central handle g above the cover over which it swings in operating the closed machine.

In operation the lever G oscillates upon the center g, the crank shaft upon the centers 6', and the rubber upon the centers 0. It will be seen that though the lever handle g be swungin a comparatively short arc the shaft E will be swung in a much longer one and may be caused to move the rubber a considerable distance though the center of the shaft is ordinarily above the trunnions upon which the rubber swings.

To remove the clothes from the tub the cover is thrown back on its hinges, the handle G being moved with it to the position indicated in Fig. 3. To release the rubber from its. engagement with the shaft E the latter is raised out of its bearings 01, and moved in the slide way a formed by the plate a secured to the edge of the tub, until the shaft is freed from the slotted post D'of the rubber thus permitting the latter to be lifted out of the tub and conveniently returned thereto and again connected to the operating gear. The

ted lever G pivoted to the tub and engaging an outside crank E of said shaft, all substantially as and for the purpose set forth.

In testimony whereof we affix our signatures 15 in presence of two witnesses.
