his invention relates to dry-room tumblers.

It has been the practice for some time to dry washed clothes in dry-room tumblers by directing a supply of hot air thereinto. Clothes are dried relatively quickly in this type of device, but it has been found that clothes dried by hot air in this manner have a very peculiar and repulsive odor.

One object of this invention is to overcome this undesirable feature in a simple, inexpensive and novel'manner. Another object is to provide simple and efficient means for deodorizing or refreshin washed clothes in a dry-room tumbler.

The invention is illustrated on the accompanying sheets ofdrawings, in which- Figure 1 is a vertical sectional view of a dry-room tumbler embodying our invention; an

Figure 2 is a partial sectional view and partial elevational view taken in the planes of irregular line 2-2 of Figure ,1.

The dry-room tumbler includes an outer casing 10 provided with a hinged door 11, whereby clothes may be laced into and withdrawn from the rotata le receptacle 12 mounted within the casing 10. Heating.

coils 13 are placed within walls 14 and 15 of the casing for heating air which is drawn thereto by means of any suitable fan 16, said fan being mounted in a casing 17 which is directly connected with the heating'compartment, the pamage of air from the fan to the heating compartment being controlled b a valve or'damper 18 pivotally mounted at 19.

This valve '18 has a depending arm 20 but also controls any exhaust from the main casing of the dry-room tumbler through the exhaust stack 27. This valve or damper 25 is pivotally mounted at 28 and has an arm 29, to which is connected'an adjustable connecting means 30, which in turn is connected to another arm 31 of the lever 24, the latter being ivoted at 32.

As s own in Figure 1 of the drawings, and v assumin that the fan 16 is in operation, air is force from the fan casing 17 past the heated coils 13 out through hot air conduit 26 past valve 25 into the main tumbler casing, in which the rotary member 12 containing wet clothes to be dried is mounted. As the rotary member continues to rotate and hot airblown into intimate contact with the hereinabove, such clothes dried in the manclothes therein, the latter become dried in a ner indicated are left with a repulsiv'eodor. To deodorize a nd refreshen the clothes dried in the tumbler, we force a supply of cold air into intimate contact with the dried clothes. This blast of cold air is preferably supplied from an independent source, for instance, through a main cold air supply conduit 33 and a plurality of branch conduits 34 which communicate with the lower part 4 eflected through the operating lever24. Re- I ferring particularly to Figure 1, it will be noted that if the lever 24 is moved to the left from the position shown, the valve or damper 25. willpbe moved into a position to check the flow of hot air through the conduit 26. Lever 24 may also be so connected that the valve or damper 18 will, at the same operation, be moved into its closed position to shut off the supply of air from the fan 16 to the hot coils 13. When the valves are in these positions, cold air may be supplied through the conduits in quedion for refreshening the dried clothes; 7

When the cold air is cut oil in any suitable ber, means for supplying a drying medium I of a receptacle in which clothes are dried,

manner, and it is-desired to direct hot air to the clothes, valve 18 may be opened any desired degree as may be valve 25. If desired, the valve 25 may be moved into position such that the exhaust stack 27 is completely cut off from the main casing of the tumbler.

Preferably, the supply of cold air through the conduits 33 and 34 is controlled by a valve 35 operable in a conduit 36 directly connected to the conduit 33, said valve having a stem 37 to which is connected an arm 38, which in turn is operatively connected to the arm 23 of lever 24:. In this Way, valve 35 for admitting or excluding the reverse flowing cold air may be operated simultaneously with the valve 25 that controls the hot air; and if the valve 18 is employed, all of the valves 18, 25 and 35 may be simultaneously controlled. Preferably, when hot air is supplied for drying purposes, cold air is cut off and when cold air is supplied for freshen'ing the clothes, the hot air is cut oif. 7

It it apparent that there may be various modifications of the invention and it is our intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

We claim:

1. In a dry-room tumbler, means for supplying a drying medium to the clothes in said v tumbler, and independent means for subjecting said clothes in said tumbler to a fresh aerating medium.

2. In a dry-room tumbler, a drying chamto the drying chamber, and independent means for subjecting the contents of said chamber to a fresh aerating medium; said independent means having a plurality of delivery passages through which it delivers said freshening medium in subdivided form and to distributed ber.

3. In a dry-room tumbler, means for supplying a drying medium flowing in one direction through the clothes in said tumbler, means for treating said clothes in said'tumbler to a fresh aerating medium flowing in another, direction therethrough, and means for selectively controlling the delivery of such mediums to said tumbler.

4. In a tumbler, the combination of a receptacle in which clothes are dried, means for causing hot air to flow through said receptacle in one direction for drying the clothes, and an independent means for causing cold air to flow throu h said receptacle 1n another direction freshenin said clothes.

5. In aaqry-room'tumbler, the combination .means for causing hot air to flow through said receptacle in.one direction for drying the clothes, an independent means for causparts of the drying cha.m

6. In a dry-room tumbler, the combination of a receptacle in which clothes are dried, means for causing hot air to flow through said receptacle in one direction for drying the clothes, an independent means for causing cold air to flow through said receptacle in another direction for freshe'ning said clothes, independent means for controlling the hot and cold air supplies, and a common means reciprocally actuating the two air-controlling means.

7. In a dry-room tumbler, the combination of a receptacle in which clothes are dried, means for causing hot air to flow through said receptacle in one direction for drying the clothes, an independent means for causing cold' air to flow through said receptacle in another direction for freshening said clothes, and independent means for controlling the hot and cold air supplies; the hot air supply means comprising an air heating compartment, means for passing air from the'heating compartment to the clothes-containing receptacle, and means for controlling both ingress and egress of the airof said heating compartment. 2 a
