DELINTING DRYING TUMBLER.

Application filed April 23,

Tb all whom it may concern Be it known that I, EDMUND I. CUTTER, a citizen of the United States, residing at ing to remove the lint from the air after its passage through the drying chamber.

The type of device to which this invention applies, as for instance the drying tumbler, comprises in general a heating chamber, a drying chamber, and an air chamber, a fan being located within the last named chamber for forcing a current of air through the heating chamber, thence through the drying chamber, whereinis contained the laundry to be dried, and thence back to the air chamber; from which point the air might be expelled from the machine casing or part of it recirculated through the machine. These several chambers have communication with each other through pas-' sages which, in the present type, are controlled by dampers operated from the outside of the machine so that air can be forced through the circuit just described during the time of drying the laundry, and by proper manipulation of the dampers the heating chamber can be eliminated from this circuit with the result that the fresh outside air is forced through the drying chamber and back to the air chamber for'the purpose of cooling the laundry before its removal from the tumbler. This particular type of device includin steam pipes 30 and ba-flie plates 35 will he more fully understood from the description set forth in the Patent No. 1,424,994, granted August 8, 1922, to this applicant.

It havingbeen found that more or less lint from the laundry is picked up by the air in its passage through the drying'cham her, it has been deemed desirable to remove such lint from the air before its return to the fan chamber or before its return to the air of the room in which the drying chamber is located. The means devised by ap plicant for accomplishing this purpose is located within the air chamber and is in communication with the drying chamber. By

prevented from 1920. Serial No. 376,135.

embodying this invention in the several types of drying machines, it will be ossible to keep the lint out of the fan, the lint will be passing through the rest of the machine and will not be allowed to pass to the atmosphere ofthe room in which the machine is located and where employees are engaged at work. Other advantages will be apparent to those who are familiar with the art.

Diiferent forms of structure out applicants invention will suggest themselves to those skilled in the art, but the form preferred by applicant will be under stood from the following detailed description and claims when considered in connection with the accompanying drawing.

AMERICAN LAUNDRY for carrying Fig. 1 1s a vertical transverse section of the combination in which is embodied applicants invention; Fig. 2 is a transverse vertical section through the 'delinting device; and Fig. 3 is a detail View partly in section of the valve used in connection with the delinting device. v

By the action of fan 4. which is covered by casing 5 within the air chamber 2, fresh outside air is .drawn through chamber 6 and forced through passage-way 7 when damper 8 is in the full line position as shown in Fig. 1; thence through the heating chamber 1- in which are located steam pipes 30, through passage-way 12 when damper 11 is in open position as shown in full lines in Fig. 1, to the drying tumbler 13 which has a wall of foraminous material. After passing through the dryingchamber the air is forced back to air chamber 2, from which chamber it is expelled from the casing through outlet 34. The tumbler 13 which is given rota motion back and forth is also provided wit' baflie members 31 and a door 33 through which access may be had to the laundry upon opening door 32 mounted on the main outside casing of the machine.

WVhen damper 8 is in open full line position as indicated in Fig. 1, and as above redotted lines in Fi 1 so that fresh outside air is then drawn by the fan from chamber 6 throu h passage-way 9 to thedrying tumbler, w ence it is forced through passa eway 14 back to the air chamber 2 and to t 1e outside atmosphere through outlet 34. In either case, as will be seen from the drawing, the air as a result of its passage through the drying tumbler 13, will gather more or less lint from the laundry. It is proposed "by applicant to remove this lint by deflectout througi openings 38 and 39 in the side wall of the machine casing, as seen in Fig. 2. The lower edge portion of plate 16 extends slightly within trough 19 and is deflected toward the drying c amber, as shown in Fig. 1, thereby forcing the air to be again deflected from the near side of the trough .andin this way cause the air to pass over.

practically the entire surface area of the fluid body. The comparatively restricted passage between plate 16. and wall 17 will give suflicient force to the air to cause the lint to be deposited upon the surface of thefluid body. This trough member 19 contains a fluid to a 'oint just below the lower edge of plate mem er 16 so as to leave a passa e-way for the air from the lower end of t e passage 15 to'the air chamber 2 without forcing the air throu h the water in trough 19. Any suitable uid ma be used, water having proved very satis actor According to aplicants invention the int will be deposited 1n the fluid contained'in trough 19 and the air allowed to pass into air cha ber 2 free of such lint, which action corres nds somewhat to that of a filter. Sincemost of this lint will remain upon the surface of the fluid in trough '19 it will be drawn off throu h over-flow pi e 23, as better indicated in Fig. 2, and t ence out through discharge25 when the valve 24, shown n Fig. 3, is in the position there indicated, a continuous supply of fluid being received through inlet pipe'20 so that'there will normally be a constant flow throu h the tro gh. That portion of the lint whic sinks to the bottom of trough 19 may be removed through pipe 22 whenvalve 24 is inposition to allow communication of the pipe 22 with discharge pipe 25, which valve position may be obtained by turning handle 26 so as to bring its lower end against stop 28. By turning handle 26 so as to come against'stop 27 the valve 24 ma be positiened as indidicated in Fig. 3. Vihth a constant fluidsupply throu h inlet 20 it will be clear that the lint will e readily removedfrom the bottom of the trough 19 u on proper setting of the valve 24. It will e apparent that the level of the fluid'in trough 19 can be regulated by adjustment of valve 24.
