20 Claims.

This invention relates to a centrifugal clothesdrying and rinsingeapparatus in 'which a vertically disposed container for the clothes is rotatably mounted within a relatively stationary up- 5- right casing or jacketcarrying at its upper end a drain-board extension which is adapted to be adjusted rotarily about the axis of the container and casing to enable the water expelled from the clothes to be discharged in different radial directions into other receptacles at different posi tions around the outside of the casing.

In this apparatus the drain-board extension is provided with a cover extending across the entire area of the upper end of thecasing and container and preferably hinged to the extension to permit it to be swung from a closed position to a fully open position, and upon which is revolubly mounted a supplemental cover or lid movable therewith into and out of frictional vengagement with the upper end of the container to rotate with said container relative to the casing and cover therefor.

These centrifugal driers are adapted to be used more 'particularly in connectiony with clothes g5 washing machines, and alsowith rinsing vats for receiving, rinsing and drying the clothes .which may be transferred thereto from other washing or rinsing vats, and one of the objects of the present invention is to provide amore convenient means for permitting-the transfer iof the clothes and the washing fluid to and from the vats which may be located'at different positions around the centrifugal drier.

Other objects and advantages relating to the :15 specific use of the apparatus will be brought out in .the following description.

In the drawings:

Figure 1 is a top plan view of thecentrlfugal drying and rinsing device and adjacent portion of 40 a washingmachine showing by dotted lines the drain-board extension in different positions of adjustment, and by full lines as registering with the top of the washing vat.

Figure 2 is an enlarged vertical sectional view partly broken away taken on line 2 2, Figure 1.

Figures 3 and 4 are horizontal sectional views taken in the planes of lines 3 3 and 4 4 respectively, Figure 2.

Figure 5 is an enlarged vertical sectional view 5o taken in the plane of line 5 5, Figure 2,

As illustrated, this centrifugal drier is mounted upon one side of the tub as A of a mechanical clothes washer. which, in turn is supported upon a horizontal platform fz of the main supporting frame. This supporting frame may also be used as a part of the supporting means for the centrifugal drier in addition to one o'r more legs a'.

The centrifugal drier, as shown, comprises an upright downwardly Itapered vat or container -I made in the form of an inverted truncated cone 5 and having its bottom and side walls imperforate, the bottom wall being mounted upon and secured to a suitable platform'or disk 2 through which the receptacle as a whole may be rotated aboutl a vertical axis. l0

The disk 2 is centrally journaled upon a. suitable bearing post 3 on an underlying portion of the main supporting frame a and also has a limited axial movement lengthwise of the bearing 3 against and with the action of a coiled spring l5 5 which forms a yielding support for the receptacle to permit the receptacle to be moved vertically into and out of engagement with a rotary driving element 6'.

This driving element 6 may be connected to any 20 available source of power such as the motor driven mechanism of the washer as shown in my pending application referred to and preferably consists of a conical friction disk adapted to be engaged by a conical friction face 2 on the disk 2 25 when the receptacle is depressed against the action of the spring 5 for engaging the disk 2 with the driving disk. v

The marginal edge of the disk 2 extends radially some distance beyond the side walls of the 30.

lower end of the vat I to form an annular brake Y,surface ID which when the receptacle I is elevated by the spring 5, is adapted to engage an overlying brake shoe I I on the bracket 9 as shown in Figure 2 for stopping the rotation of the re- 35 ceptacle when disengaged from the driving element 6.

The upper or larger end of the container I is provided with a lider closure I2 rotatable therewith, but adapted to be displaced when necessary 40 to permit the insertion and removal of clothes into and from the open upper end thereof.

The main body of the receptacle I is preferably made of sheet metal and is provided at its upper end with an outwardly and downwardly extend- 45 ing marginal flange I3, while the lid I2 is also provided with a marginal flange I2' overlying the adjacent portion of the flange I3 and preferably corrugated at I4 at intervals throughout its periphery to form a series 'of discharge passages I5 50 leading from the interior to the exterior oi' the container I, 'said lid being also provided with a depending annular flange I6 within the upper end of the vat I in spaced relation thereto to form the inner walls of the passages I5. 55

The object of these passages I5 is to permit the escape of any fluid which may be expelled from the clothes by centrifugal force as the receptacle I with the Wet clothes therein is rotated at a more or less high rate of speed which causes the water to pass upwardly along said walls and tlrough the passages I5 over the top of the flange 'Ihe rotary container I is surrounded by a relatively stationary upright casing I1 which extends nearly the full length of the container in radially spaced relation thereto, and is provided near itslower and upper ends with internal reinforcing rings I8 and I9 and together with said rings is secured to the adjacent side of the vat A by bolts I9' and I9', Figure 2.

The upper ring I9 forms an annular bearing for receiving and supporting an annular extension 20 of the casing I1 and permitting said extension to be adjusted rotarily, and for this purpose said extension 20 is provided with a peripheral groove for receiving the ring I9 which also serves to hold the extension against axial movement.

'I'his extension 20 is provided in its upper face with an annular channel 2I which underlies the outer edge of the iiange I3 for receiving the overflow water from the passages I5.

The extension 20 is also provided with a laterally projecting shelf or drain board 22 which may be adjusted to different radial positions by the rotary adustment of the extension 2liv to permit `the overflowing suds and other washing or rinsing iluid from 'the container to be returned to the washing vat'or to other receptacles at different positions aroundthe container, and also to facilitate the transfer of the clothes to and from the container and to and from different receptacles. -1

This shelf 22 is provided with a branch passage 23 leading laterallyrfrom one side of the trough or conduit 2I tangential to the corresponding side of therevoluble receptacle I for conducting the water expelled from the clothes by the rotation of the receptacle from the conductor 2| into the washing or rinsing vat for re-use, or to any other place desired.

A cover 24 is movable to and from a position across the upper end of the vat I directly -over the lid I2 and for this purpose is hinged at 29 to one side of the upper end of the extension 29 while its opposite side is movable into and out of engagement with the corresponding side of the extension 20 and is provided with a locking member 26 movable into and out of engagement with a keeper 21 on the shelf.

The locking member 29 is secured to the lower end of a spindle 29 which is journaled in the adjacent portion of the cover 24 and is provided at its upper end with an operating handle 29 by which it may be turned to move the lock 21 into and out of engagement with its keeper.

'I'he lid I2 is mounted upon the cover 24 to open and close therewith and in order that it may be free to rotate with the receptacle I relatively to the cover I2 it is centrally journaled upon the lower end of a post 39, which, in turn is journaled in a central bearing 3I in the cover 24 and is provided with an operating handle 32.

A cam collar 33 is secured to the intermediate portion of the post 30 between the lid I2 and cover 24 and is provided with a cam face 34 adapted to engage a companion cam face on the underside of the adjacent portion of the cover, whereby the rotation of the post 39 in one direction by means of the handle 32 will force the receptacle I downwardly against the action of its retracting spring 9 for engaging its friction face 2' with the driving element 9 whereby rotary motion will be vtransmitted from said driving element to the receptacle I including its lid I2 about the vertically alined axes of the co-axial bearing posts 3 and 39.

Suitable means is provided for preventing the opening of the cover 24 and lid I2 when the receptacle I is being rotated by its driving element 9 and also for preventing the axial operation of said receptacle into engagement with its driving element, while the cover 24 and lid I2 are opened to reduce the liability of danger to the operator by contact with the rotating parts and escape of fluid by upward displacement into the room in which the machine is located, and for this purpose is provided a locking bolt 3l which is slidable endwise in suitable bearings in the cover 24 between the post 39 and spindle 29, or rather between the collar 33 and hub of the handle 29, Figures 2 and 5.

T'he cam collar 33 is provided with a lengthwise peripheral groove movable -into and out of registration with the Iinner end of the locking bolt 35 as the handle 32 is adjusted rotarily to different positions indicated by full lines and dotted lines in Figure 1, while the hub of the handle 29 is provided with a circumferentially extending peripheral groove movable into and out of registration with the outer end of the locking bolt 35 as the handle 29 is adjusted to `different, positions.

During this rotary adjustment of the handle 32 and cam 33 the latter will ride against its companion face on the underside of the adjacent portion of the cover 24, thereby forcing the receptacle I downwardlyl toengage its lower friction face 2 with 4the dri'ing element W for imparting rotary motion to the receptacle.

As long as the handle 32 and its cam collar 33 remain in their adjusted positions for eecting the rotation of the receptacle I, the lever 29y and its locking member 29 will be held against return movement to their releasing positions by the engagement of the inner end of the locking bolt 39 with the periphery of the cam collar 33, and

therefore, the cover 24 and lid I2 cannot be released for opening until the lever 32 and its cam collar 33 are returned to their starting positions.

When the lever 32 and its cam collar 33 are returned to their starting positions as just described, the locking lever 29 may be turned to release its locking member 29 from engagement with the keeper 21, during which operation the periphery of the hub of the handle 29 will be brought into engagement with the locking bolt 35 for forcing the latter endwise inwardly Into engagement with theregistering groove in the cam collar 33.

The cover 24 is provided with one or more airvent openings 39 to prevent the trapping of the air in the chamber between the cover 24 and lid I2 and thus permit the free exit of the fluid expelled from the clothes by centrifugal force through the passages I9.

If desired, the post 39 may be provided with a central lengthwise passage 39 therethrough from end to end, and a spray nozzle 49 at its inner end, while the outer end may be connected by a dexible conduit 4I to any available source of supply for rinsing water, or for air, either warm o" cold, under pressure as maybe required for expediting the cleansing and drying of the clothes in the lto the receptacle.

Operation When it is desired to dry a set batch of clothes which have been previously washed in the washing machine A', the cover 2l is first unlocked by the proper adjustment of the handle 29, after which the cover with the lid I2 thereon is opened about the axis of the pivot 25.

The clothes which have been previously washed in the washing machine A are then withdrawn by hand over and along the shelf 22 and dropped into the open upper end of the-receptacle until the latter isK substantially filled, whereupon the cover 24 with the lid thereon is returned to its closed position and locked by the proper adjustment of the handle 29. Immediately following this operation,V the lever 32 will be adjusted rotarily to force the receptacle I downwardly into engagement withits driving element 6 which may be rotated by any suitable driving mechanism for imparting rotary motion As the receptacle I with the wet clothes therein is rotated at a relatively high rate of speed. the water therein is expelled by centrifugal force laterally and upwardly along the side walls of the receptacle I .and outwardly through the passages I5 into the trough 2| from which itis free to 'escape through the tangential passage 2l into the tub A or into any other suitable receptacle, during which operation a rinsing uid or air under pressure may be introduced into thereceptacle through the passage- I9 and nozzle 40 for expediting the cleansing and drying of the articles in the receptacle. 3

It is found that the upwardly daring imperforate wall of the receptacle greatly facilitates the escape of the expelled water-over the upper edge thereof, and that a thorough drying of the articles may be accomplished in a relatively short period of time, leaving said articles in a'uy `condition ready for ironing.

AIn removingthe clothes from the receptacle, the handle 32 must be first returned to its starting position to release said receptacle from engagement with its driving element 8, thereby allowing the spring 6 to lift the receptacle and to cause its brake surface I0 to engage the stationary brake member AIIfor quickly stopping'the rotation of the receptacle.

Immediately following the release vof the rel ceptacle from engagement with its driving'element, theliandle 29 may be adjusted to. unlock.` the cover 24, thus permitting said cover with the lid I2 thereon to be fully opened, whereupon the practically dry clothes may be removed by hand through the upper open end of the receptacle, the machine being then ready for a repetition of the oprations previously described.
