HTraR EYs Patented Sept. 2, 1930 UNITED STATES PATENT OFFICE WALTER A. PAPWORTH, OF SYRACUSE, NEW YORK., ASSIGNOB T SYRACUSE WASH- ING MACHINE CORPORATION, OF SYRACUSE, NEW YORK, A CORPORATION 0F DELA# WARE CENTRIFUGAL CLOTHES DRIER Application led January 19, 1926. Serial No. 82,251.

This invention rela-tes to a. centrifugal clothes drier.

These centrifugal driers are adapted to be used in connection with .washing machines as a substitute for the usual wringers for drying the clothes immediately following the washing operation and are preferably attached directly to the washing machine frame or wash tub to become a unitary part of the io laundrying outfit but obviously may be used independently thereof.

In the use of centrifugal driers of this type in which the clothes receptacle is adapted to revolve about a vertical axis the fiuid exi5 pelled from the clothes by centrifugal force impinges against andrises upwardly along the side walls of the receptacle so that if provision is made for the discharge of the fluid overv the upper marginal edge of the 2o receptacle the bottom and side walls may be made imperforate and one of the objects of the present invention is to provide means at or near the top of the imperforate receptacle and preferably between the lid and marginal edge thereof whereby the fiuid expelled from the clothes by centrifugal force may overflow into a receiving'conduit or annular trough having a suitable discharge.

Another object is to provide this annular 3o conduit or trough with a tangential branch discharge vpassage projecting laterally therefrom in such manner that the overflowing Huid may be discharged into an adjacent tub forreuse in washing, if desired.

Another object is to provide for a limited axial movement of the receptacle whereby it may be moved into and out of engagement with its driving means.

A further object is to provide automatic brake means for stopping the rotation of the receptacle after it has been disengaged from its driving means.

The receptacle is provided with a removable lid rotatable therewith and preferably 5 mounted upon a suitable cover which is movable to and from a position across the open upper end of the-receptacle and one of the linvention and adjacent portion of the tub of a mechanical washer to which i-t is attached, the dotted lines indicating different positions of adjustment of the drain board.

As illustrated, this centrifugal ndrier is mounted upon one side of thel tub as" A of a mechanical clothes washer which, in turn, is supported upon a horizontal platform a 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 or more legs a The centrifugal drier, as shown, comprises an upright downwardly tapered vat or container 1 made in the form of an inverted truncated cone' having its bottom and side walls imperforate, the bottom wall being mounted u on and secured to a suitable platform or disk 2- to form a part thereof and also to serve as means through which the receptacle as a whole may be rotated about a vertical axis.

The disk -2- is centrally journaled upon a suitable bearing post -3- on an underlying portion 4- of the main supporting frame -aand also has a limited axial movement lengthwise of the bearing `3 against and with the action of a coiled spring 5 which surrounds the post -3- and 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 is secured to a horizontal shaft 7 which is journaled in suitable bearings 8 in a bracket -9- on thek main supporting frame -a-, said shaft being adapted to be connected to any available source of power such as the motor driven mechanism of the washer or to a separate motor if desired.

The drivin element 6- preferably consists of a con1cal friction disk adapted to be engaged by a conical friction face 21- on the disk -2- when the receptacle Ils depressed against the action of the spring for engaging the disk -3- with the dr1ving disk.

The marginal edge of the disk -2- extends radially some distance beyond the side walls of the lower end of the vat -l-v to form an annular brake surface -10- which when the receptacle -1- is elevated by the spring -5- is adapted to engage an overlying brake shoe -1lon the bracket Q- as shown in Fig. 2 for stopping the rotation of the receptacle when 'disengaged from the driving element -6-.

The upper or larger end of the contanier H1- is provided with a lid or closure l2- rotatable therewith but adapted tol be displaced when necessary to permit the inse`rtion and removal of clothes into and from the open upper end thereof.

The main body of the receptacle -1- 1s perferably made of sheet metal and is provided at its-upper end with an outwardly and downwardly extending marginal flange 13- while the lid -12- is also provided with a marginal flange -12- overlymg the adjacent portion of the flange --13- and preferably corrugated at 14- at intervals throughout its periphery to form a series of discharge passages -15- leading from the interior to the exterior of the container -1-,

said lid being also provided with a depending annular flange -16- Within the npper end of the vat -1- in spaced relation thereto to form the inner walls of the passages -15-.

The object of these passages -15- and i6- is to permit the escape of any fluid which may be expelled from the clothes by centrifugal forceas the receptacle -1- with secured to the mai'n supporting frame through the medium of an annular ring 19 and is provided with an upwardly extending cast metal extension #-20- having an annular groove -21- underlying the outer edge of the flange -13- and constituting a conductor for receiving the fluid which'may be discharged through the passages -16- and,l

The side of the extension 20- adjacent the tub -A- is provided with a laterally and downwardly extending shelf or drain board Q2- arranged to overlie the upper end of they tub to facilitate the transfer of the wet clothes from the washer tank A to the receptacle 1 when the lid -12- is removed or opened.

This shelf -22- is provided with a branch passage 23- leading laterally from one side of the trough or conduit 2ltangential to the corresponding side of the revoluble receptacle -1- for conducting the Water eX- pelled from the clothes by the rotation of the receptacle from the conductor -21 into the washing or rinsing vat for reuse, or to any other place desired.

A cover 24- is movable to and from a position across the upper end of the vat 1- directly over the lid l2- and for this purpose is hinged at -25- to one side of the upper end of the extension -20- whilelits 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 -27- on the shelf.

The locking member `--26- is secured to the lower end of a spindle -28- which is v 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 Q6- into and out ofengagement with its keeper.

The lid -12 is mounted upon the cover -24- tov open and close therewith and in order that it may be free to rotate with the receptacle -1-- relatively to the cover Q4- 'it is centrally journaled upon the lower end of a post F30- which, in turn, is journaled in a central bearing -31- in the cover 24- and 1s provided with an operating handle A cam collar 33- is secured to the inter. mediate portion of the post -30- between the lid -12- and cover Q4- 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 30- in one direction by means of the handle 32 will force the receptacle 1 downwardly against the action of its retracting spring 5- for engaging its friction face 2'- with the driving element -V-6- whereby rotary motion will be transmitted from said driving element to the receptacle -lincluding its lid l0-- about the vertically alined axes of the coaxial bearing posts -3- and -30-.

Suitable means is provided for preventing the opening of the cover 24 and lid -12- when the receptacle -l is being rotated by its driving element -6- and also for preventing the axial operation of said receptacle into engagement with its driving element while the cover Q4-.and lid .-12- are openedto reduce the liability of danger to the operator by contact with the rotatingparts and escape of fiuid by upward displacement into the room in which the machine is located and for this purpose is provided a locking bolt -35- which is slidable endwise in suitable bearings in the cover Q4-'- between the post- 30'- and spindle 28- or rather between the collar 3- and hub of the handle QQ-1 Figs. 2 and 5.

The cam collar -33- is provided with a lengthwise peri )heral groove movable into and out oi registration with the inner end of the locking bolt -35- as the nhandle -32- is adjusted rotarily to different ositions indicated by full lines and dotted ines in Fig. 1, while the hub of the handle Z9- is provided with a circumferentially extending peripheral groove -37- movable into and out of vregistration with the outer end of the locking bolt -35- as the handle 2.9- is adjusted to different positions.

The length of the bolt -35- is substantially equal to the distance between the base of each groove of the corresponding parts and the adjacent portion of the periphery of the other part white the grooves are so relatively arranged that when the cover -24- and lid l2- are closed and the handle -29- is turned to its locking position indicated by dotted lines in Fig. l, the groove 37 will be registered with the adjacent end'of the locking bolt -35 at which time the handle -32- and its cam collar -33- may be adjusted rotarily to the position indicated by dotted lines iIi Fig. l thereby causing one of the beveled walls of the groove -36- to ride against the adjacent end of the bolt -35- for forcing said bolt endwise or outwardly into the registering groove S7- Of .the handle --29-v while the inner end 0f the bolt will ride against the periphery of the collar 33- for holding the bolt in its adjusted position.

During this rotary adjustment of the handle -32 and cam -33 the latter will ride against its companion face on the under side of the adjacent portion of the cover -24- thereby forcing the receptacle -1- downwardly to engage its lower friction face -2- with the driving element 6- for imparting rotary motion to the receptacle.

It is now evident that as long as the handle -32 and its cam collar -33 remain in their ad'usted positions for effecting the rotation o the receptacle -l the lever -29 and its locking .member -26- will be held against return movement to their releasing positions by the engagement of the inner end of the locking bolt -35- with the periphery of the cam collar 33 and, therefore, cover 24- and lid 1Qf cannot be released for o ening until the lever -32- and its cam col ar 33 are returned to their starting positions with the groove -36- in registration with the inner end of the locking bolt -35- at which time the receptacle -lwill have been elevated out of engagement with its driving element -6- by the spring 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 26 from engagement with the keeper -27- during which operation the periphery of the hub brought into engagement with the locking bolt -35- for forcing the latter endwise inwardly into engagement with the registering groove -36- in the cam collar 33-.

The cover -34- is provided with one or more air-vent openings -38- to prevent the trapping of the air in the chamber between the cover 24- and lid -l2- and thus permit the free exit of the fluid expelled from the clothes by centrifugal force. through the passages -15-.

If desired the post 30- may be provided with a central lengthwise passage 39T- therethrough from end to end and a spray nozzle *4G-at its inner end while the outer end may be connected by a flexible conduit 41- to any available source of supply for rinsing water or for air, either warm or cold, under pressure as may be required for expediting the cleansing and drying of the clothes in the receptacle -lduring the rotation thereof or While the fluid is being expelled therefrom.

clothes which have been previously washed in the Washing machine -A, the cover -Qeis first unlcked by the proper adj 11Stofthe handle -29- will beiV llG ment of the handle -29- after which the cover with the lid 12 thereon is opened about the axis of the pivotv-25.

The clothes which have been previopsly washed in the washing machine -A- are then withdrawn by hand over and along the shelf -22- and dropped into open upper end of the receptacle until the latter is 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. y

Immediately following this operation the lever 32 will be adjusted rotarily to force the receptacle -1- downwardly into engagement with its driving element -6- which may be rotated by any suitable driving mechanism for imparting rotary motion to the receptacle.

As the receptacle -1- with the wet clothes therein is rotated at a relatively high rate of speed the water therein is expelled by centrifugal force laterally Aand upwardly along the side walls of the receptacle -l and outwardly through the passages l5- into the trough -21- from which it is free to escape through the tangential passage Q3- into the tub -A- or into any other suitable receptacle during which operation a rinsing fluid or air under pressure may be introduced into the receptacle through the passage -39- and nozzle -40- for expediting the cleansing and drying of the articles in the receptacle.

It is found that the upwardly flaring imperforate walls of the receptacle greatly facilitate 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 fluffy condition ready for ironing.

In removing the 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 -6- thereby allowing the spring -5- to lift the receptacle and to cause its brake surface -10- to engage the stationary brake member 11 for quickly stopping the rotation of the receptacle.

Immediately following the release of the receptacle from engagement with its driving element the handle -29- may be adjusted to unlock the cover Q4- thus permitting said cover with the lid -12- 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 operations previously described.
