DRIER AND DEODORIZEB.

"Application filed .Tune 13, 1925. Serial No. 37,001.

This invention relates to driers and deadapted to dyeing plants and cleaning plants, although 1 do not wish to be limited to any especial adaptation of the invention.

The invention articularly relates to the class of driers an deodorizers of the cabinet type comprising an inclosing casing in which the articles to be treated may be suspended from a rotatable carrier in a manner to permit air to be passed through the fabric to evaporate the moisture and carry off the odors. The air is preferably dry and in order to obtain the best results it should be admitted at a relatively low temperature at such an angle to the carrier that the incom- "ing air will serve as the-propellin medium to impart a rotative movement to e carrier, and in this connection it may be well to state here that the inlet conduit has two nozzlelike passageways, either of which ma be renderedeifective while the other is ineffective, so that the air may be admitted to the casing to impinge against the fabric on the carrier on either side of the center of the carrier. Therefore the carrier may be rotated in either of two directions.

- Means is also provided for varying the effective port areas of the nozzle-like passageways to vary the velocity of the air as it enters the casing. Means is also provided for cutting off the main conduit from the source of supply when the air impeller ceases to function, so that danger of odors escaping from the casing toward the source of supply will be avoided.

There are other more or less important features incorporated in my invention. These will be specifically referred to hereinafter reference being had to the accompanying drawings, in which- Fig. 1 is a perspective view of the upper part of the. drier constructed in accordance with my invention.

Fig. 2 is a transverse sectional -view through the, s upply conduit, the inlet branches, {and throughthe main part of the casing, certain;o ther parts being shown in elevation.)

-Fig, is ;a ver tical longitudinal sectional r ewthrongha th dr erfi-Figis; an; enl arged; perspective view of tliehand wheels for controlling the valves for the nozzles and the deflector valve, and

Flg. 5 is a perspective view of the impeller supporting ring.

The cabinet in which the articles to be treated are received is shown as comprising a casin 1, preferably cylindrical and consisting of two spaced walls l and. 2 provided with a door 3 so that access may be had into the casing. The space 4 between the walls 1 and 2 is preferably .filled with strips of insulating material, for example, fibre. By reference to Fig.3 it will be observed, that the ends of thewall members are connected by top and bottom members 5 and 6. Within the casing is a rotatable spindle 7 supporting a carriage 8 which constitutes a support for the articles to be treated. The articles are preferably hung from the peri hcry of the carriage. The casing is provided with two

inlets

9 and 10 separated by a V- shaped wall 11, and they communicate with noz'zles or passageways 12and 13, in turn communicating with an air supply conduit 14. The air supply conduit may receive air from any suitable source, the velocity of the air being stepped up by an impeller shown as a motor driven fan 15-fastened to the ring 16 carried by the. partition 17 in the conduit 14, The conduit 14: is provided with an openin 18 normally closed by a shutter 19 whic is adapted to be swung aside for the purpose of permitting an oiler to be introduced into theconduit 14 to oil the fan motor. The shutter 19 also serves as a damper to vary the efi'ective port area of the opening 18 so that if necessary the air supply opening 20 in the reduced end 21 of the conduit 14 may be augmented. The

openings 20 do not supply all of the air for the drier, but in order to increase the absorptive capacity of the air it is sometimes necessary to heat it, so if the air is entering the conduit 14 at too high a temperature, atmospheric air will be let into the conduit 14 to reduce the tem erature of the air supply from the norma source of supply.

The air impeller structure is' supported on the ring 16 (by reference to Fig. 5) which it will be observed is provided with a sound-deadening filler or ring 22. This ma consist of felt or any other suitable materia In front of the impeller is a damper 23 damper 23. However, when the air impeller is operating the force of the air blast against 7 the damper 23 will be suflicient to overcome the counterbalance weight 26,- so that air can be forced into the casing. It will be seen that whenever the air impeller stops operating the damper will be efi'ective to close on communication between the source As an important improvement my inven-' tion contemplates the provision of means for directing air to either side of the center of the casing and of the spindle 7. This is accomplished by swinging the deflecting valve 27 about its pivot at the apex of the member 11 so that when it strikes against a cleat 28 it will close off port or nozzle 12, and when it strikes against a cleat 29 it will close off conduit or nozzle 13'. The pivot for the valve 27 consists of a stem 30 having a hand wheel 31 on the outside conduit 14 so that the valve can be swung back i and forth.

It is desirable to change the eifective port and 37 on their ends outside. the conduit,

velocity of the air, and vice versa.

so that they can be turned. The angle at which the

members

32 and 33 are .swu'ng across the conduits 12 and 13 'will determine the eifective port area of the particular nozzle involved, it being obvious that the more the nozzle is restricted the greater

file e stems

34 and 35 outside the conduit are provided with

ratchets

38 and 39 adapted to be engaged by

pawls

40 and 41, and each stem carries a pointer 42 movable over a scale 43. The pointer will indicate the position of the valve in the nozzle conduit, and the dog or pawl will hold the stem against rotation in one direction.

Of course some means must be provided for exhausting the air, so I have provided an exhaust port 44 on the bottom of the casing which may lead to atmosphere.

On the bottom member 6 is. a bearing base member 45 in the form of a ring, that is, it-

is provided with a circular flange 46 which carries a plurality of radially disposed screws 47 adapted to press against and i of air supply or the atmosphere, and the cas- .ried by the top 5. The extension may be adjustable vertically by loosening the setv screws 55' and 56 so that the points properly bear against the recess portionsof their bearings or against the Walls of the cups.

The spindle can be adjusted to a true perpendicular position by adjusting the screws 47 so as to insure that the adjustable cup member 48.will be in accurate alignment with its complementary bearing member 53. The means for locating the spindle in the casingis elaborated in my application #755,861, so a more extended description of the same in this application is considered unnecessary.

Fromthe foregoing it will be apparent that the carriage may be rotated in two directions so that air can act on the front and back of the fabric, that is, on two sides of the fabric, the alternating operation re sulting in a more eflicient dr 'ng and deodorizmg than can-be accom 'shed with a single passage way to the caslng.

The means of introducing air into the casing, its control means, and the eflicient way in which I eliminate liability of odors passing back through the nozzles to atmosphere, all tend to enhance the value of a 7 device of this kind.

What I claim and desire to secure by Letters-Patent is:

1. In a drier and deodorizer, a casing having two air inlets for directing air into the casing on opposite sides of the axial center of the casing, a rotatable clothes carrier in the casing, means for feeding air to the inlets, and means for alternately directing the air through the inlets so that the air will impinge against the clothes to cause the clothes carrier to rotate.

2. In a drier and deodorizer, a casing having two nozzle-like inlets for directing air on opposite sides of the axial center of the casing, a rotatable clothes carrier in the casing, means for feeding air to the nozzlelike inlets, means for directing air into first one inlet and then the other, and means for varying the efi'ective port areas of the "nozzle-like inlets.

against the clothes to rotate the carrier, and means for alternately directing air into first one inlet and then the other.

4. In a drier and deodorizer, a casing having two air inlets and an air outlet, the inlets being located to direct air into the casing on opposite sides of its axial center, a clothes carrier rotatable about the axial center of the casing, independent valve means for the inlets, and means for delivering air to the inlets.

In a drier and deodorizer, a casing having air inlet means and air outlet means, a clothes carrier in the casing, an air impeller for delivering air through the air inlet means to the casing, a horizontally pivoted counterbalance baflie between the air impeller and the casing.

7. In a drier and deodorizer, a casing having an air inlet means and an air outletmeans, an air impeller in the inlet means, the inlet means comprising two nozzle-like tubes discharging into the casing on opposite sides of its axial center, valving means in the tubes, a deflector for directing the air from the impeller into either of the tubes, a yielding battle between the impeller and the tubes, and a clothes carrier in the casing.

8. In a drier and dcodorizer, acasing having an air inlet means and an air outlet means, an air impeller in the inlet means, the inlet means comprising two nozzle-like tubes discharging into the casing on opposite sides of its axial center, valving means in the tubes, a deflector for directing the air from the impellerinto either of the tubes, a yieldingbafiie between the impeller and the tubes, and a clothes carrier in the casing rotatable about the axial center of the cas ing, so that air delivered into the casing from the tubes will impinge upon the clothesto rotate the carrier.
