7 Claims.

This invention relates to new and useful improvements in a cleaning apparatus.

The invention has for an object the construction of a cleaning apparatus characterized by the provision of a housing having a partition located therein for dividing the same into a reservoir chamber for cleaning fluid within the bottom portion thereof, and a cleaning fluid chamber in the top portion thereof and within which a perforated drum is rotatively mounted and arranged in a manner to receive the clothing to be cleaned.

Still further it is proposed to provide a pumping system for pumping the cleaning fluid from the reservoir to the cleaning fluid chamber and arranged to pump the fluid to the cleaning fluid chamber at a greater speed than bypass permits the cleaning fluid to flow back into the reservoir from the cleaning fluid chamber.

Still further it is proposed to characterize the pumping system by a removable strainer between the pump and the cleaning fluid chamber to strain all of the cleaning fluid from the cleaning fluid chamber.

Still further it is proposed to construct the device in such a manner that the drum will rotate at a given speed while the cleaning fluid is being circulated through the device and to stop the circulation of the fluid to permit all of the fluid to drain from the cleaning fluid chamber into the reservoir, and to then step up the rotation of the drum to centrifugally throw as much of the cleaning fluid as possible out of the clothing at the completion of the cleaning process.

Still further it is proposed to arrange an adjustable valve between the cleaning fluid chamber and the reservoir which is adapted to be adjusted as desired for controlling the rate of flow of the cleaning fluid from the cleaning fluid chamber to the reservoir.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accenipanying drawings, and to the appended claims in which the various novel features of the invention are particularly set forth.

Each of these free ends is provided with a screw 59 which is adapted to be tightened to bear agains a top face of the cover 46 and to hold the same in a tightly closed position.

A pumping system is provided for drawing the cleaning fluid from the reservoir Ill and discharging the same into the cleaning fluid chamber l More specifically, this pumping system is characterized by a centrifugal pump 5I mounted upon the base I2. A pipe 52 connects with the interior of the reservoir Ill and with the pump 5I for permitting the operation of the pump to draw the cleaning fluid from the reservoir I0 A second pipe 53 connects the pump 5I with the interior of the cleaning fluid chamber II) for discharging the cleaning fluid into the cleaning fluid chamber III The pump 5| is electrically operated and is capable of supplying the cleaning fluid to the cleaning fluid chamber Ill at a speed greater than the bypass is capable of permitting the fluid to pass from the chamber Ii] back into the reservoir Ili The discharge end of the pipe 53 is connected with a strainer mounted upon the bottom face of the cover 46 for straining all of the cleaning fluid before it enters the chamber I9 This strainer is characterized by a flat container 54 mounted on the inside face of the cover 46 and which has an open side 55. A removable strainer is adapted to be engaged into the container 54 through the open side 55. More specifically, this strainer is characterized by a metallic plate 56 extending from the open side of the container 54 to a position adjacent the opposite side thereof.

A piece of cloth 51 is engaged around the plate 56 and is securely held in position by means of bars 58 securely attached to the opposite faces of the metallic plate 56. A second strip of cloth material 58 is engaged around the cloth material 51 and has its free edges securely attached to the outside faces of the bars 58. The bars 58 are provided with openings '60 arranged .in .a manner :to require the cleaning :fluid to pass through the filter strip of cloth material 159 before it may pass into the cleaning fluid chamber IO One of the bars 58 is provided with a handle 6| which is adapted to be grasped for pulling the strainer from within the container 54 for permitting the pieces of cloth material 51 and 59 to be interchanged when they become clogged with dirt strained from the cleaning fluid. A novel means is also provided for connecting the interiorof the container '54 with the discharge end of the -pipe 53. This means comprises a small section of pipe 62 which connects with the interior of the container 54. This pipe 62 is adapted to engage into an enlarged opening 53 formed on the free end of the pipe 53. The cleaning fluid passing up the pipe 53 will enter the pipe I52 and pass into the container 54 through the pieces of filter cloth and 59 and discharge through the openings =60.

The pipe vI52 is also provided with a novel means for closing the end thereof when the cover 46 is moved to an open position to prevent any cleaning fluid remaining therein from dripping therefrom. This means comprises a valve having an element 63 rotati'vely extended into the bottom of the passage .62. This element 63 has a conical shaped opening and a conical shaped member -64 is adapted to engage into the conical shaped opening for closing the same. A bridging element 6:5 is attached to the element 63 and extends across the top face of the conical shaped memberM and is spaced therefrom.

A spring 66 operates between the bridging element 65 and the top face of the conical shaped member for urging the same into a closed position when the cover 46 is in an open position. However, when the pipe 62 is engaged into the end of the pipe 53 a means is provided for urging the conical shaped member 64 into an open position as shown in Fig. 9 to permit the cleaning fluid to pass therethrough. This means comprises a stem 81 extending from the conical shaped member 64 and which is provided with an enlarged head 68. A pin 69 is diametrically across the interior of the pipe 53. When the pipe 62 is engaged into the pipe 53 the head 68 is adapted to strike the pin 69 and urge the conical shaped member 64 into an open position against the holding action of the spring 66.

A novel electrical means is provided for controlling the operation of the pump motor 5| and the drum motor 3|. The electrical connections for this novel operation are shown in Fig. 17 and comprise a pair of leads I9 which are connected with a source of power. One of the leads III is provided with a main time switch H which is adapted to be manually closed for completing the electric circuit.

The electrical connection for the drum motor 3| will first be given. This means comprises a lead I2 extending from the time switch II and which connects with a second time switch I3. This time switch I3 has a pair of spaced contacts 13 and 13 A lead I4 extends from the contact 73 and connects with one pole of the drum motor 3|. This lead I4 carries a minimum rheostat l5. A lead It connects with the other pole of the motor 3| and back to the source of power. A lead 11 connects with the other contact 73 of the time switch I3 and the lead I4. lead 1-! carries a maximum rheostat I8.

The connection of the pump motor 5| is as follows:

A lead I9 connects with the lead 12 between the time switch II and the time switch I3 and is connected with a third time switch having a contact 80. The contact 8|] of the time switch 80 has a lead 8| connected therewith and which is also connected with one pole of the pump motor 5|. A lead 82 connects with the other pole of the pump motor 5| and carries back to the source of power.

When the main time switch II is closed electric current will pass through the time switch 80 and supply current to the electric pump motor 5| for pumping t-hecleaning fluid from the reservoir I 0 to the cleaning fluid chamber Ni Current will also pass through'the lead I2 and the contact I3 of the time switch I3 and through the minimum rheostat 15 to provide a minimum of electric current to the drum motor 3| to turn the drum I5 slowly while the cleaning fluid is being circulated through the cleaning apparatus for cleansing the clothes contained within the drum I5. After the pump motor 5| has been in operation for a given period of time, controlled by the switch til, the switch 80 will open and the pump will no longer circulate the fluid through the cleaning apparatus.

Thedrum I5 will continue to rotate slowly for a given amount of time, permitting all the cleaning fluid within the chamber IO to pass through the bypass and into the reservoir I9 After all the fluid has passed from the cleaning fluid chamber the time switch I3 will switch to cause the current to pass through the contact 13 and maximum rheostat "I8 to step up the rotation of the drum motor 3|. This will cause the drum I5 to rotate at a much greater speed to permit centrifugal force to throw off the cleaning fluid from the clothes within the drum I5. After the drum I5 has rotated at this high speed for a given amount of time, the time switch 'II will automatically open and the cleaning operation will be complete.

The operation of this invention is as follows:

The cover 46 is moved to its open position and the cover I6 of the drum I5 is also opened to permit the clothing to be engaged within the perforated drum I5. The cover I6 is then closed and the cover 46 is also closed. The apparatus is then ready for cleaning clothes. The same is accomplished by manually closing the time switch 'II mounted upon the face of the housing II]. The closing 'of the time switch II will cause the time switches "I3 and '80 to automatically operate to circulate the cleaning fluid through the cleaning apparatus to stop the circulation and step up the rotation of the drum I5 to centrifugally throw oil" the cleaning fluid from the clothing and to stop the rotation of the drum when the cleaning fluid is all thrown therefrom. After the cleaning operation has been completed the cover 46 is again opened and the cover I6 is also opened and the cleaning clothing is removed from the drum I5.

It is to be understood that one or more filter units may be used with the same outlet, in this device, oi" any desired shape.
