DRYRGOII TUMBLER.

Application led January 2e, 1920. Serial No. 353,730.

To all whom t 'may concern.:

Be it @own that I, WILLIAM R. HAGER, a citizen of the United States, residing at Chicago, in the county of Cook and, State of Illinois, have invented certain new and useful Improvements in Dryroom Tumblers, of which the following is a specication.

This invention relates to dryroom tumblers.

1l@ 'As is well understood in the art, it is common practice to provide driving mechanism for dryroom tumblers whereby the rotatable member in which clothes are dried is rotated 'a given number of revolutions in n@ one direction and then reversed to rotate a given number of revolutions in the opposite direction. Under such conditions the air driven into the lrotary member for drying the clothes therein, is not at all times directed upon the clothes -for quickly and eciently drying same.

-Acoordingly, one object of my invention is to direct the flow of air to the rotatable member in which clothes are dried in a manner such that the clothes at all times are under the drying influence of the drying medium.

Another object is to provide a dryroom tumbler with means whereby the clothes eo therein may be dried more quickly and in a more approved and efiicient manner.

,These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in

et which- Figure 1 is an end elevation, parts being in section, of a dryroom v.tumbler embodyingjmy invention; and,

igure 2 is a top plan view of the same, e0 parts being broken away and showing operative parts of my invention.

The various novel features of the invention will be apparent from the following description an drawings and will be particularly pointed out in the appended claims.

ferring to the figures of the drawings, it will be noted that I have shown al dryroom tumbler having the usual outer casto ing 10, including a pivotally mounted door 11, by means of which clothes are placed into and withdrawn from the rotary membar 12 ofthe dryroom tumbler, it being understood that the rotary member is mounted upon a shaft 13 suitabl supported in bearings o the housing. ne compartment 14 within the housing 10 is provided with the usual heating coils 15 past which air. is

`blown by a fan 16, the casing 17 of which of hot air is directed into the rotary member 12 for drying the clothes placed therein. As is well understood, it is common practlce to drive the rotary member 12 a given number of revolutions in one direction and then reverse the rotary member for driving the same a given. number of revolutions in the op osite direction. With this in mind, it will e Vapparent that if the rotary clothes containing member 12 is rotating in a counterclockwise direction, as viewed in Figure 1, the'hotair 'passing through opening 19 will be directed against the clothes, which will pile up on the right-hand side of the rotary member, thereby playing directly upon the clothes therein for eiciently dryingthe same at. such time. Un the other hand, however, when the rotary member 12 is reversed and rotates in a clockwise direction, as viewed in Figure 1, it will be ap.

preciated that the clothes will pile upon the left-hand side of the rotary member and that the hot air which passes through opening 19 will not come into direct vengagement for eiciently -dryin the clothes, but, on the other hand, will be y-passed-through the rotary member 12 lon the right-hand side of t e same. Therefore, v.the drying medium will be ecient for drying clothes only when the rotary member is rotatedin one direction; To overcome this undesir-r able feature, I have provided l'means where# by a drying medium may be supplied directly against theA clothes in the rotary.

ico

clothes-containing member 12 regardless of its direction of movement. To accomplish this result, I have 4provided a second open,` ing 20 in the inner wall 21 of the passageway 18. Thereb the drying mediummay be directlysupp ied to the clothes in the rotary member when the latter is rotated in aclockwise direction. In order to h-ave a strong blast of air and to have the maav from this point of view, I have provide a valve or damper 22 in the passageway 18 which may be moved into one position for closing the o ning 20 and permitting airto flow t rough the assageway 18 and through the opening 19 or drying the clothes when the rotary member 12 is rotating in a counterclockwise direction. This damper 22 also may be moved'into a position to close the passageway 18 above the opening 20 to prevent the passage of air to the opening 19 and causing the flow of the drying medium Ithrough the opening 20, whereby the drying medium will be supplied directly against the clothes in the rotary memberl 12 when the Ia'tter'is rotating in a clockwise direction.

.It-will be a preciated, of course, that the operation of t is damper 22 to be eifect1ve must be automatic.

rovided means whereby the damper 22 will be moved from one position y5to the other upon a chan e in rotation of 'the rotary member 12.A his means includes a wheel 23 mounted upon the shaft 13, said wheel having a surface which cooperates with a shoe 24 pivotally connected to' an arm 25, one end of which at 26 is pivotallyk connected to one end of a link 27, the other end of which is pivotally connected at 28 to an arm 29 fixed' to the pivotal rod-30 of the damper 22. An intermediate portion of the arm 25 is provided with an elongated slot 31 for the reception of the reduced end 32 of a stud 33 secured to one end of the casing 10 in any suitable manner'. A. j

.Secured tol the stud 32 is one.end of a spring 34, the other end of which 'is secured to an ear 35 formed on the arm 25 near the upper end thereof, the action of the spring being such afs to yieldably hold the arm 25 in its downward imitin'g position. in which the stud 32 occupies the upper extreme end of the slot 31.

As shown in full lines in'Figure 1 of the drawings, it will be noted that the shoe 24 is at the rightfhand side of the wheel23 and that the damper 22 is in a position to pre" vent the flow'of air to the opening 19, but permitting the low of air through opening 20 for causing a flow of air directly upon the clothes in the'rotary member 12 with the latter rotating in a clockwise direction. With the parts in these positions, it will be .understood that if th'e rotary member. is

v now reversed in its rotation so that it rotates in .a counterclockwise direction, as viewed in Figure 1, the shoe 24 engaging the peripheral surface of the wheel 23 will be caused Accordingly, I have to ride thereon in a counterclockwise direction, thereby overcomin the action of the spring 34, the arm 25 rst raising so that the stud 32 occupies the lower extremity of slot. 31 and the arm at the same time pivoting about the stud 32, causing the damper 22 to move into a position closing the opening 20 `to permlt the flow of hot air through the conduit 18 and opening 19 against the clothes whichare no w piled up on the righthand side of the rotary member 12 as a result of the counterclockwise rotation of the latter. Likewise, the damper 22 will be moved into its full line position when the rotary member 12, andtherefore the wheel 23,-is reversed' and moved in a clockwise direction.

In this way the clothes in the rotary mena ber are dried quickly and satisfactorily with the air at all times directed against the .clothes in a manner to produce the best results, the action throughout bein automatic. v It is my intention to cover al modifications of the invention falling within the spirit and scope of the following claims.
