Roberts Att0mey.-Imirie & Smiley [5 7 ABSTRACT A device for washing pots and pands and the like. The device includes a motor having a flexible cable for powering, mechanically, a handheld unit which receives various rotatable brushes.

2 Claims, 3 Drawing Figures 5/1966 Springer 15/28 PATENTEDFEBUIQB 3'715'770 INVENTOR. CARLOS E OBIPEGON- GOMEZ WASHING APPARATUS This invention relates to power driven scouring machines, and more particularly to a washing apparatus for pots and the like.

It is therefore the primary purpose of this invention to provide a washing apparatus which will safely and effectively provide a means of scrubbing or scouring pots.

Another object of this invention is to provide an apparatus of the type described which will have the electric drive motor remotely connected to a flexible shaft member in order that there will be no shock hazard when using the apparatus.

Another object of this invention is to provide an apparatus which will have an on-off switch in the handle of the hand-held portion which will also change the speed of the rotary brush shaft in order that the apparatus may be adapted for various washing jobs.

A further object of this invention is to provide a washing apparatus which will have a plurality of changeable brushes, each being suitable for a particular washing operation and the brushes will all have quick connecting and disconnecting means carried therein so that the brushes may be readily changed within a,

minimum of time.

Other objects of the present invention are to provide a washing apparatus which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a side elevation of the hand-held member of the present invention, showing a brush separated therefrom;

FIG. 2 is a side view of the entire apparatus comprising the invention; and

FIG. 3 is a plan view of a set of movable brushes, each for a specific task.

According to this invention, a washing apparatus is shown to include an electric motor 11 having a flexible cable 12 which is secured to one end of housing 13.

Housing 13 is a handheld member of apparatus 10 and includes a handle 14 which carries a switch 15.

On the interior of housing 13 a gear 16 secured to flexible cable 12, engages a gear 17 carried upon a shaft 18, the shaft 18 being carried within journals 19.

A step-pulley 20 is secured to shaft 18 and gap belt 21 which is also carried upon a step-pulley 22 carried on a second shaft 23 which is rotatably carried within journals 24 and 25 on the interior of housing 13.

A speed changing rod 26 extending from handle 14 into the housing 13, allows for shifting the belt 21 to another ratio of speed, the belt 21 being carried within the end of rod 26.

A shank portion 27 extending outwards from the shaft 23, is provided with a key-way 28 within a socket 29 opening through the end of the shank portion 27.

An outwardly urged springy key 30 of the brush shaft 31 provides quick disconnect and connecting means for the brush shaft 31 to the shank 27 of housing 13, the key 30 being received within the key-way 28 of shank 27 in order to use the apparatus 10. The brush shaft 31 is provided with a plurality of bristles 32.

As will be seen in FIG. 3 of the drawing, a plurality of brush shafts 31 for different tasks are rovided with suitable bristles 32', the brush shaft 31 0 FIG. 3 being interchangeable with that shown in FIG. 1.

It shall be noted that the flexible cable 12 may be modified to carry wires for a reostat (not shown) for controlling the speed of the brush shaft 31 and sliprings may also be employed for connecting the switch 15 to the wiring of the motor 11 as is well known in the art.

In use, the motor 1 1 is stationary and the handle 13 is grasped by the housing 14 in order to operate apparatus 10.

The switch 15 in the preferred! embodiment shown could change the speed of the brush shaft 31 when it is urged downwards by the operators thumb.

When it is urged downwards the attached rod 26 will move the belt 21 to another speed ratio effected by the steppulleys 20 and 22.

The brush shafts 31 are snappily engaged within the shank 27 of housing 13 by means of the spring operation of key 30 engaging or disengaging the key-way 28 of the shank 27.

What I claim is:

l. A washing apparatus comprising power drive means, an elongate housing having a handle for manual support thereof during operation of said apparatus, said handle extending longitudinally of said housing, flexible cable means connected with said drive means and extending into one end of said housing and secured to a drive member within said housing, said drive member being disposed on an axis extending longitudinally of said housing, a shaft rotatably supported by and within said housing adjacent said drive member and perpendicular to the axis thereof, a second shaft parallel with said first mentioned shaft and rotatably supported by and extending from the other end of said housing, the extended end of said second shaft carrying implement supporting means, a second drive member on said first shaft in driving relation to said first mentioned driving member, speed change transmission means within said housing and including a pair of step pulleys respectively mounted on said shafts and a belt trained around said pulleys, and manually operable switch means on said handle and including a member extending into said housing and connected with said belt for regulating the speed transmitted to said second shaft byshifting of said belt between the steps of said pulleys.

2. Apparatus according to claim 1 wherein said implement supporting means on the extended end of said second shaft comprises a socket, a washing implement including a spindle having a free end removably insertable in said socket, and cooperative releasable latch means in said socket and on said spindle for releasably retaining said implement in operative position.
