WASHING-MACHINE.

Application fil ed October 17, 1919.

electric motor. .Other suitable drivingv power, however, such as a hydraulic motor, could equally well be employed for this purpose. The invention has for its objects to provide a novel construction and arrangement of parts for insuring a uniform and even rocking movement of the tub; to provide means for preventing the actuating mechanism from stopping on a dead center,

and to mount the tub in such a manner that the danger of injury to the operator by having the hand caught in any part of the mechanism, or between the tub and a fixed part of the machine is practically obviated.

In addition to the above specific objects of the invention, other objects reside in the simplicity of the construction involved and the advantages derived from the general construction of the machine as a whole, all of which will more clearly appear from the description to follow: p

In the accompanying drawings, v

Figure 1 is a side elevation of a machine constructed according to my invention with the casing broken away to illustrate the motor drive;

Fig. 2 is a broken longitudinal sectional View of the same;

Fig. 3 is a plan view of the casing and the operating mechanism mounted therein, the tub being removed; and

Fig. 4c is a central vertical section taken on the line 2-4 of Fig. 2.

Referring now to these drawings, the numeral 1 indicates a casing closed on all sides, preferably of metal and rectangular in shape, supported by legs 2 and having an elevated bottom 3, on which, near one end of the casing, is mounted a motor 4-, the shaft of which is provided with a drive pulley 5. The driving mechanism includes a crossshaft 6 suitably mounted within the easing 1, which has secured thereon, at one end,

opposite sides of the casing 1. The shaft 11 has loosely mounted on its end, remote from the gear-wheel '10, a sleeve carrying a crank arm 13, which is pivotally connected at its outer end to the lower end of a pitman rod 14 as indicated at 15. The upper end of the pitman rod 14 is pivotally connected at 16 to a lug 17, on one end of a rocker frame 18. The sleeve is provided with a fixed clutch member 19, and the shaft with a movable clutch member 20, which is splined on said shaft, and a throw-lever 21 is provided for operating the movable clutch member. This clutch mechanism is of the usual, or any preferred construction, as common in machines of this character, and is illustrated merely for the purpose of makin the operation of the machine clear. The rocker frame 18, previously alluded to, comprises two parallel 'members, each of which is formed preferably of a metal bar bent to provide a rocker 22 (Fig.2) and a longitudinal member 23 located above the rocker, the two members 23 forming a bed or tubholder for supporting the bottom 24 of the tub 25. The bars 23 have upwardly turned integral extensions to engage the ends of the tub and the rockers 22 in each instance, preferably unite and are jointly curved upwardly at their opposite ends, as indicated at 26 in Fig. 2, to provide a support and holder for the rounded corners 27 of the tub. The tub 25 is provided at its ends and either side, with suitable means which may be in the form of continuous flanges 28 which embrace the outer sides of the rocker frame 18 to prevent lateral movement of the tub in the frame.

From the construction described. it will be seen that the tub when set in the rocker frame 18. will be held in position therein by means of the curved projections 26 at the ends of the rocker frame and by the flanges 28 embracing the opposite sides of the rocker frame. without any other means of holding the tub in place being required. The construction permits the tub to be readily placed in position in the rocker frame and as readily removed at all times by simply lifting the tub off the tub holder. The two members of the rocker frame are connected at their 0 posite ends by cross-bars 29, on one of whlch the lug 17, previously referred to, is mounted. I provide suitable means forpreventing the rocker frame from creeping along the supporting led es, preferably constructed as follows wardly from each of the longitudinal members 23 of the rocker frame is a bracket arm 30, (Figs. 2 and 4), the lower ends of thesebracket arms being connected by'a cross-bar 31. The numeral 32 indicates two parallel pivot barswhich are pivotally mounted at their outer ends at one end of the casing 1, as indicated at 33 in Figs. 2 and 3, and at their inner ends are pivotally mounted on the cross-bar 31. Extending longitudinally of casing 1, nearopposite sides thereof, are two parallel angle bars 34 which serve, respectively, as the ledges or supports for the rockers 22, and on which the curved lower edges of said rockers rest and roll, in the operation of the machine. The side flanges 35 of these bars embrace the outer sides of the rockers 22 and thus serve to prevent latarm 13 will be caused to be rotatedand reciprocate the pitman 14, which movement of the pitman will impart a rocking movement to the tub 25; the latter will be held to a central position on the angle bars 34 by means of the pivot rods 32 engaging the cross-bar 31. There will be a slight sliding movement of the rockers 22 on these angle bars, but in actual practice with a full-size machinejsuch sliding movement scarcely exceeds one-sixteenth of an inch in extent, and does not affect the even rocking movement of the tub.

He'retofore, it has been attempted to secure the tub in position in its rocking movement by means of a pin and double slot connection, and I originally employed such a construction. It was found, however, that such an arrangement was not feasible, as the movement, or throw of the water and the clothes in the tub was with such force as to cause an end-wise movement of the tub and thus destroy the correct .alinement of the pin rojecting downter.

connected at one end to t 1 These objections are overcome in the present ing misplaced in movement, and hence vibration and noise are reduced to the minimum.

- One of the objects of the invention has been stated to be the prevention of the op: erating mechanism stopping on a dead cen- This' object is accomplished through the medium of a coil-spring 36 which is e cross-bar 31 and atthe other end to the pitman rod 14, about mid-way of the length of the latter, as shown in Figs. 2 and 3. This spring will operate to pull the pitman rod 14 to the position shown in Fig. 2 Whenever the power is turned off, in which position the pivot 15 is out of the line of thrust, as will be seen.

The final object of the invention is concerned withpreventing injury to the hand of the operator, and relates to the provision of means for effectively guarding the driving mechanism, at the same time providing a construction rendering the motor and driving mechanism readily accessible. This object is effected by inserting the 1 tub 25 through an opening 37 in the top of the casing 1, and positioning the angle bars 34 well below the top of the casing, so that the rocker frame, as a whole, is below the top of said casing, and the mechanism of the machine is below the tub in the casing and guarded on all sides by the casing. It is impossible, therefore, for the operator or a child to get fingers caught beneath the rocker and the fixed part of the casing or to come into contact with any'of the driving parts, and there is no part of the tub which approaches sufficiently close to the edge of the opening 37 to cause injury to the hand of the operator, even should it be inserted-in the said opening. -But the starting lever is accessible through the opening and access may be readily had to the mechanism through the top opening 37 by removing the tub and the holder.
