WASHING-MACHINE Specification of Letters Patent.

Patented June 15, 1909.

To all whom it may concern:

Be it known that I, JAMES KoLnx', a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in vI/ashinghliachines; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheets of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to improvements in washing machines; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate this invention more fully, Figure 1 is a longitudinal sectional elevation on line 3/ y of Fig. 5. Fig. 2 is an elevation of the mechanism by which the rubber and the dashers are actuated. Fig. 3 is a sectional elevation of the same on line w m of Fig. 2 in the direction of the arrows shown in said Fig. 2. Fig. 4: is an elevation of one of the mutilated gear-wheels. Fig. 5 is a plan of the machine. Fig. 6 is a plan of one of the dasher stems, and Fig. 7 is a plan of one of the dashers. Fig. 8 is a plan of the rubber, showing a modified form of the same. Fig. 9 is a plan of the preferred form of said rubber.

Like parts are designated by corresponding symbols and characters of reference in all the figures.

A, in these drawings designates the tub. It is, by preference, a rectangular structure, but may also be of any other desirable contour, and it is mounted upon a trestle B, made either a permanent fixture of the tub, or a separate structure adapted to receive said tub. The bottom 10, of this tub A is, preferably, constructed with a flat upper surface to receive a bearing or step 11, for a vertically disposed shaft 12, to which reference will hereinafter be more fully made.

To the tub A is hinged a section 14, of the cover for the tub by hinges 13, there being a convenient handle 15, for manipulating said cover-section 14L. There is upon the tub hinges 17; buttons 18, being provided by means of which the cover-sections are locked to the tub.

Upon the cover-section 16 there is mounted a standard G, fitted with bearings 19 and 20, wherein is journaled a shaft 21, one end of which is supported in said bearings 19 and 20, while the opposite end is journaled in a bearing 22 on a standard 23. The end of the shaft 21 projecting beyond the side of the tub A carries a fiy-wheel D, to steady the movement of the operating mechanism, it being provided with a suitable handle 24:, by means of which the fly-wheel is rotated.

The standard C has near its inner terminal a downwardly-projecting bearing 25, to receive the tubular boss 27 of a bevel-pinion 26, said pinion 26 having an upwardly projecting stud 28, which is adapted to revolve in a bearing 29, Figs. 1 and 2, formed on a standard E, said standard E being transversely bored through a hub 30, for the passage of the shaft 21. The upper end of this standard E is bifurcated at 31 to receive a lever F, the outer ends of which are pivoted, by means of pins or bolts 32, to dasher-stems G and H.

Upon the shaft 21 there are secured, by set-screws 33, or analogous means, mutilated gear-wheels I and J, one of which is shown in detail in Fig. 4:, there being on said gearwheels a segment of a bevel gear 35 and 134:, and segments of spur- gearing 35 and 135, the former being adapted to mesh with the pinion 26, and the latter with racks 36 and 136, secured to the sides of the dasher-stems G and II, respectively, in such manner that when the parts of this mechanism are assembled, as shown in Fig. 2, these racks are the same side of the shaft 21.

On the under side of the standard C and the standard 23 there are formed sockets 37 and 38, respectively, the former to serve as a guide for the dasher-stem G, and the latter for its companion stem H. In these dasher-stems there is a slotted aperture 39, Fig. 6, through which the shaft 21 passes and which shaft, therefore, serves as an additional guide for these dasher-stems. To the lower end of these dasher-stems are removably secured dashers K, which are, preferably, of horseshoe contour and perforated by a series of holes 410, and having an extension 11, also perforated, as shown in Fig. 7.

The vertical shaft 12 is squared at it upper end 42, to engage with the correspondinglyshaped bore in the hub 27 of the bevel pinion 26, and it is pointed at its lower end 43, to engage the step 11 on the bottom of the tub A. Upon this shaft 12 and near its lower end, there is secured a star-shaped rubber L, shown in detail in Fig. 9, provided with ribs 49. In operation, this rubber L, which may also be a disk as shown in Fig. 8, is intermittently rotated by the mutilated bevel-wheel segments alternately engaging the bevel-wheel 26, that is to say, there are several dwells in every revolution of said rubber, the length of the dwells and the distance through which the rubber moves at each movement depending upon the number of cogs in the bevel-gear segments. At the same time, or approximately at the same time, that the bevel-gear segment 34 of the gear-wheel I reaches the bevel pinion 26, the spur-gear-section 35 engages the rack 36 on the dasher-stem H, and moving it upward, causes a corresponding downward movement of the dasher-stem G, through the intervention of the rocking lever F. The two segment-gears I and J are placed upon the shaft 21 in diametrically opposite directions so that when the gear-section I operates the dasher-stem H, the gear-section 135 on the dasher-stem G is disconnected from its respective rack 136 on said dasherstem G, thereby permitting the latter to descend, but as soon as the segment-gear 135 reaches the rack 136, the latter will be upwardly moved to return to its first-described position. At the same time the bevel-wheel segment 134 has revolved the bevel pinion 26 a partial revolution, this alternate and intermittent movement of the dashers and the rubber continuing as long as the shaft 21 is revolved. I

The clothes to be washed are introduced to the tub through the opening covered by the cover-section 14 and they are washed and cleansed by the joint action of the dashers and the rubber.

The mechanism in the interior of the tub may be easily removed therefrom by swinging the main section 16 of the cover on its hinges 17, when the shaft 12 will separate from its stepbearing 11 and also from the boss 27 of the bevel-pinion 26. The dashers K can be separated from their stems G and H by loosening the set-screws 45 therein, and the dasher-stems pulled upward after removing the bolts 32 that connect them with the rocking-arm F, so that all the in- I terior mechanism can be thoroughly cleansed It is advisable that all of the metallic parts entering into the construction of this washing machine be galvanized to protect them from rust. These parts are very simple in construction; they can be readily cast in metal, and require but very little machining, and they can, therefore, be manufactured at a minimum cost.

Having thus fully described this invention, I claim as new and desire to secure to me by Letters Patent of the United States-- 1. A washing machine including a tub; a main cover on said tub; a standard upon said cover and secured thereto; bearings on said standard; a main shaft in said bearings; two oppositely disposed mutilated gear-wheels upon said shaft, each gearwheel having a segment of a bevel-Wheel and a segment of a spur-gear; two dasherstems adjacent to said mutilated gearwheels, racks on said dasher-stems; a dasher on each of said stems; a bevel-pinion adapted for engagement by said bevel-segments; a vertical shaft removably engaging said bevel-wheel, a rubber on the end of said vertical shaft, and a rocker-arm connecting the upper ends of said dasher-stems.

2. A washing machine including stand ards having bearings, a shaft in said bearings; two oppositely disposed mutilated gear-wheels upon said shaft and adjacent to said bearings; two dasher-stems; racks on said dasher-stems adapted for alternate engagement by said gear-wheels; a rocker-arm connecting the upper ends of said dasherstems, and a pivotal bearing for said rockerarm.

3. In a washing machine, means for intermittently rotating a rubber, said means including a standard; bearings on said standard, a main-shaft in said bearings, two oppositely-disposed bevel-wheel segments upon said shaft; a bevel-pinion between said bevel wheel segments and adapted for operative engagement by saidbevel-gear segments, a vertical shaft upon which said bevel-Wheel is mounted; a step-bearing for the lower end of said vertical shaft, and a rubber on the lower end of said vertical shaft.

In testimony that I claim the foregoing as my invention I have hereunto set my hand in the presence of two subscribing'witnesses.

JAMES KOLIN.
