Job Huichinson Patented July 4, 1950 UNITED STATES PATENT iOF'F'ICE WASHI G MACHINEDBIVE I Job Hutchinson, Great Neck; NY. nppiieaeenseetember 23, 1947; serial No. 7751.576 1 invention 'relates'to' new and useful improvements in washing devices'an'd has particular reference to washers which can be easily and quickly placed into andremoved from tube or basins asauiiit.

It is an object of this invention topi'ovide a simple, compact, "washing devicewhichcan be placed into'a til-band connected to a source of power 'to' effectively agitate the water in which it 'is' placed while'at'the same time "being entirely immune from said liquid while in the tub.

Further, it is an object to provides. simple rugged device composed of component units which can be assembled with ease'and with equal ease taken apart for replacement, inspection, and repair. I

A further object is to provide a device wherein the various units forming the complete unit can ice manufactured separately and then quickly assembled so'as-to reduce cost'and labor involved in the manufacture of the-deV-iceand so that when one unit wears out it can be replaced without the customer having to. buy a completenew unit.

Further and more specific objects; features and advantageswill more clearly appear from a consideration' of the-detailed specification hereinafter set forth especially when'taken in connectionwith the accompanyingdrawings which illustrate several forms which the invention may assumeand Which forms 'part of the specification.

In brief and general terms theinvention concerns the provision of acasing-having an oscil'latable cap'on'which are removably disposed paddles preferably extending down along the side of the casing. Within the casing is a motor'and gear worm unit also separately removable as a unit therefrom a'nd'inclu'ding-drive elemerits such as disks with -eccentric pins thereon'pi'eferably driven in opposite directions. On the cap is disposed a driven element which may hinthe form 'of a dependent element or flange engaged by 'thepins so as to be os cillated lba'ck and forth to oscillate the ca and thus the paddles. In "one form the driven element may includeseparate pivoted dependent arms backed by afspring to engage thepins and increase the quietness ofthe operation. 1

Referring now'merely to the preferred form of the 'inv'entions'hown in the drawingspit is seen that" there is provided a casing H3, preferably cylindrical in section and of considerable depth, closed at the bottom and open at the top. To this 'cas'ingis'integrally connected a much larger base l I. III and theup'per face of the base plate I! are provided with reinforcing ribs l2 in order to give the same effect to the clothes as would'loe given by a'was'hboa'rd. v

The casing It is provided with an oscillatable cap I3 having a peripheral flange I4 fitting in a liquid tight manner around the upper edge of the casing. To the top of this cap l3 are removably fastened a pair of paddles l5 by means of-bolts I6. These paddles have apertured portions l1 extending down along the sides'of the casing I I]. In the modified form of'paddle shown in Fig. 4, the paddles have an extension l8 which may be supported therefrom on extension rods 19 seated in suitablebores in the main portion of the paddle l5.

illustrated in the "drawings, of

Connected to the underside ofthe cap l3by erred formwhich the invention- The outer walls of the casingmeans of bolts 20 (see Fig. 3) is a driven plate or element 2| having a chord-like dependent integral flange 22. This is adapted to be engaged byeccentric pins 23 mounted on disks 24 supported on disk shafts 25. These disks are disposed above a frame formed by connected

spaced plates

26 and 21 and between these plates the disk shafts 25 are connected to worm gears 28 driven by a common worm 29 on a shaft 3|] carrying a belt pulley 3| connected by a belt 32 to a similar pulley 33 on a shaft 34 of a motor 35. This. motor is mounted in any suitable manner on a base plate 36 having on its under side a groove 31 adapted to receive a rib 38 formed on the floor of the casing l and diametrically disposed on said floo-r. The

frame plates

26 and 21 are supported from the plate 36 by means of legs 39. It will be clear then that the disks, their operating gears, the motor and the connections between the motor and the gear train are one unit supported within the casing and separable therefrom merely bybeing lifted therefrom as desired. It is also clear that the cap and the paddles are separable and that the cap and/or the paddles can be removed as a unit from the casing since the driven flange 22 is not positively connected to the driving pins. It is shown that the disks drive the pins in opposite directions.

In the modified form shown in Fig. 6, the flange 22 is cut away on opposite-sides of its central hub 40 and in these cut-away portions are pivotally disposed arms 4| to be engaged by the pins 23. These arms are backed resiliently by a spring plate 42 fastened to the hub 40 and are intended to resist the thrust of the pins on the arms. This construction will permit a more quiet operation than the one shown in Fig. 1. The arms 4| are dependent essentially from the cap through the intermediary of the flange 22 in which they are disposed.

In order to bring electric power into the casing it is accomplished in the following manner:

The motor wires 43 are passed through a hole in a boss element 44 disposed centrally on top of the frame plate into which is screwed one threaded end 44 of a hollow bushing 45 which passes through a central hole in the flange plate 2|. The opposite threaded end 46 of said bushing is screwed into a recess in the bottom of a cup-shaped receptacle 4'! disposed in the bore of an upright sleeve 43 integral with the cap l3. In this receptacle is disposed any suitable connection box 49 from which wires 50 may be led to a source of power. Surrounding the top of the box 49 and the receptacle 41 is a cup of insulating material which can be slipped over these elements in a suitably tight manner.

In Fig. is shown the casing ID with the cap l3 and to the side walls of the casing is attached by any suitable means an overflow pipe 52 extending down to the drain outlet in the bottom of the basin in which the device is disposed. The top of the pipe 52 is disposed at a predetermined level so that there will be an overflow when the liquid in the tank or basin reaches a e finite level. It is also seen that the bottom of the base plate H is provided with rubber suction disks 53 at spaced points to facilitate the firm adherence of the device within the the pin passes around and away from this portion of the flange. At the same time the other pin has been moving counter-clock-Wise and will engage the other end of the flange as it reaches its furthest clock-wise swing and this engagement will then oscillate the flange back in a counterclock-wise direction to its former position. Thus the cap and its attached paddles will be oscillated back and forth and effect the washing desired.

The auxiliary paddle blades l8 are'shown to obtain a more thorough movement of the liquid when the dimensions of the tub or basin permit. It is seen that the device comprises four main separable parts. First the paddles can be easily removed from the cap; second the cap and the flangeor driven element thereon can be lifted readily out of the casing; third the power unit comprising the motor, the gear train and the disks can be lifted right out of the casing when the cap is removed; and fourth the casing itself which can be firmly adhered to the bottom of the basin but as readily removed when desired. Thus all-parts can be readily taken apart at any time with ease and dispatch for replacement, inspection, and repair as wished.

While my machine is waterproof and can be immersed without danger of leakage, an auxiliary shield member 55 is provided to extend over the belt pulley 3| and down to the base. By the same token, on the other side of the machine is furnished a shield member 56 to completely shield the motor in the event that any water should be splashed into the mechanism.

As shown in Figures 8 and 9 the casing it may be permanently Welded or built into the sink unit 69, having a conventional dish sink El and a tub operation 62. In the particular housing shown there is provided between the tubs a rib 63 upon which the wringer can be mounted.

In all respects the operation of the machine is as heretofore described. I

While the invention has been described in detail with respect to present preferred forms which it may assume, it is not to be limited to such details and forms since many changes and modifications may be made in the invention without departing from the spirit and scope of the invention in its broadest aspects. Hence, it is desired to cover any and all forms and modifications of the invention which may come within the language or scope of any one or more of the appended claims.
