To all whom t may concern;

Be it known that we, Vieron lil. donano and lhiisnin ll. ltaiurnn, citizens oit the llnited States, residing at Chicago, in the a county ot Cook and State ot lllinois, have jointly invented certain new and usetul llmprovements in Dryroom 'll`umblers, oit which the following is a specilication.

'lhis invention relates to dryroorn. turnla blers ot that class in which means are provided for causing a current ot hot air tor drying purposes and a current ot cold air tor aerating, deodorizing, and treshening purposes to traverse the rotary tumber at will7 la such, tor instance, as illustrated in application Serial No. Sttl, tiled March 10, 1920, by Leslie lil. liamper, Victor 1E. ddland, and William Bartholomew.

rllhe object ot the present invention is to ao improve the details ot construction ol a machine of this type, in order to obtain better distribution ot the cold air and better control ot the valves which open and close the various air circulating passages.V

-'ll`he invention will be tully understood trom the itollowing detailed description with reference to the' accompanying drawings, and the novel features thereof will be particularly pointed out in the claims.

lln said drawingsligure 1 is a vertical transverse section; ltigure 1a a detail view in section on the line mi-11x ot Figure 1; and Figure 2 a iront elevation partly in section ot a ma- 35 chine embodying the several features ot the invention.

1 represents the casing containing the rotary tumbler 2, to which clothing or other articles are introduced alter being subjected t to dry cleaning or other cleansing process. At the back ot the machine is the usual air heating chamber 3 with coils 4l. rlhis chamber has a discharge Hue 5 controlled by valve o which delivers hot air to the top ot the t5 -tumbler 2, and said chamber receives its supply ot airl from the ian 7 past the valve 8 at the bottom ot the machine. Fan 7 is located in an intake chamber 9 which is adapted to receive air that has passed the 50 tumbler 2 through a port 9a controlled by a valve 10, also tresh air through outside port 11, the capacity ot which can be regulated by slides 12.

ln order to deliver tresh air to the tumbler 2, an air trunk 13 is mounted upon the 55 top ot the machine and provided with a leed pipe 1t controlled by valve 15, and a plurality ot distributing pipes 16 which deliver over the tumbler 2 in position to direct a number oit streams oit air downward to upon the clothing as they are tumbled within the tumbler. For tree escape ot this cold fresh air and unobstructed dow through the tumbler, a discharge chamber 17 is provided in the bottom ot the machine which is sepa- 65 rate and distinct troni the intake chamber 9. 'lFhis chamber is provided with an outlet port 18 controlled by butterdy valve 19. ln order to control the How oitY air through the several passages, the valves tl, 8, 10, and 18 are 7o connected tor simultaneous operation by a system ot levers and connecting rods which will now be described.

lFulcrumed at a suitable point, tor instance, upon the shatt 20 is a lever 21 con- 75 nected by rod 22 with al lever 23, which is in turn connected through rod 24: with an arm 25 rigidly connected with the valve 10 so that when the` lever 21 is thrown in opposite directions valve 10 will be opened and closed. 80 ll/lounted to partake ot the movement ot the valve 10 is a screen 26 which assumes a straining position across the too ot the independentY discharge chamber 17 when the valve 1,0 is closed and cold air is dowing through the tumbler, but assumes a straining position over the port 9m when valve 10 is open., thereby being adapted to collect the lint that is borne by the air :trom the tumbler 2 tor both the drying and aerating op- 90 erations. Also connected with lever 21, above its shalt 20, is a rod 19m connected to an arm 19b on the shalt 19 in order to open and close the valve 18., Also connected with the lever 21, and located at its lower end, is a rod 27 which leads to an arm 29 rigid with the valve 8; also a rod 29 which leads to belt shitter 30 (not ot m invention and not requiring detailed description) so that thel tan 7 may be stopped and started accord-'109 ingly as the valves 9 and 10 are closed or opened.

Rigid with the arm 28 is an arm 31 Which is connected by rod 32, extending substantially vertically at the back of the machine, to an arm 33 which controls the valve 6. ligid with arm 33 is an arm 34 connected by rod 35 with the damper valve 15 in the fresh air supply pipe 14.

The valve operating connections are so disposed that whenever the lever 21 is thrown to the right in Figure 1 and the valves 10, 8, and 6 are open and the fan controller 30 has started the fan, valves 15 and 18 Will be closed and the screen 26 Will lie across the port 9a; but When the lever 21 is thrown to the left, valves 10, 8, and 6 will be closed, fan controller 30 will stop the fan 7, valves 15 and 18 will be opened, and screen 26 will lie across the air passage to the discharge chamber 17.

Among the important features of the invention are the location at the top of the machine of means for delivering a plurality of streams of fresh air, the location of the discharge for. fresh air at the bottom of the machine, the separation of the chambers 9 and 17 so that the chamber 9 may have its means for controlling intake of air for diluting the hot air that is circulated without complication with the discharge of fresh air, and the general direction of the valve controlling connections which extend across the bottom of the machine from front to rear, thence up at the back of the machine to the top, and thence forward across the top.

I claim:

1. A dryroom tumbler having a casing and a tumbler therein for goods t0 be dried, means for supplying both drying and freshening air to the tumbler, and independent means for receiving from the tumbler the respective kinds of air thus supplied.

2. A dryroom tumbler having a casing and a tumbler therein for goods to be dried, means for supplying both drying and freshening air to the tumbler, and independent means for receiving from the tumbler the respective kinds of air thus supplied; each of said air receiving means having its own independent means of control.

3. A dryroom tumbler having a casing and a tumbler therein for goods to be dried, means for supplying both drying and freshening air to the tumbler, and independent means for receiving from the tumbler the respective kinds of air thus supplied; the

means for receiving drying air being adapted to return the same Ifor circulation through the tumbler.

4. A dryroom tumbler having a casing and a tumbler therein for goods to be dried, means for supplying both drying and freshening air to the tumbler, and independent means for receiving from the tumbler the respective kinds of air thus supplied; the means for receiving drying air being adapted to return the same for circulation through the tumbler, and having means independent of the fresh air inlet for admitting fresh air to dilute the drying air that is returned to circulation.

5. A dryroom tumbler having a casing and a tumbler therein for goods to be dried,

means for supplying both drying and freshf ening air to the tumbler, and independent means for receiving from the tumbler the respective kinds of air thus supplied, there being a common air screening means movable into the path of either the drying air or fresh air outlet.

G. In a dryroom tumbler, the combination of warm and fresh air supply passages respectively delivering to the tumbler at top, warm and fresh air'receiving means at the bottom of the tumbler, valves controlling the respective passages which deliver air at the top of the tumbler, valves controlling the flow of air through the respective means at the bottom of the tumbler, and a common actuating means for all of said valves.

7. In a dryroom tumbler, the combination of Warm and fresh air supply passages respectively delivering to the tumbler at top, Warm and fresh air receiving means at the bottom of the tumbler, valves controlling the respective passages which deliver air at the top of the tumbler. valves controlling the flow of air through the respective means at'the bottom of the tumbler, and a common actuating means for all of said valves, comprising a lever s vstem with connecting rods extending across the bottom of the machine from front to rear, thence upward at the back of the machine, thence across the top of the machine from rear to front and having connection with the various valves to be controlled.

Signed at Chicago, Illinois, this 14th day of July, 1921.
