www @gw wa* To all whom i't may concern.'

Be it known that I, Emmi E. Paname, a 'citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new-and useful Im rovements in Dryin Rooms, of

which tie following is a speci cation.

This invention re ing kilnsiind more plarticularly to 'the dryingrooin itself and as, for one of its riinanyJ/objects, the provision of a drying roqm equipped with dryin a varatusi which will be chea to instal ,'e cient in y, its loperation and w ich can be regulated to a fine degree of ncety to produce the ref quired' temperature, air circulation and humidity necessary f or the drying of ar- Ati'cles or materials of various characters. The invention will be best understood by reference to the following description when considered in' connection with the' accom- Vpanyin whic-hs owe a perspective'view of a d ing *t room embodying one form of the inven ion. From the drawings it will be observed e; 'that the room roper comprises a lurality of walls 6, ,and spaced apar to roy vide dead air insulatin the room. Obviously,t econstruction of the walls may vary widely in dierent'installations, the particular structure disclosed in the present instancebeingmerel I n, the obect of the wall constru ion being to f-f provi e a room with heat insulatin which will plrevent dissipation and oss of heat from t e interior of the room. The floor 9, which'may be o any preferred cony struction, ina be equipped with rails upon which cars o materia may be transported to and from the room, or suitable racks or ix hangers may be provided within the-room a.' supported. These mechanical details, how- .,f. ever, will be madejn each instance td conform to the requirements of the particular gli: material or articles to be dried. i The heat is supplied to the room by means of coils 10 sup rted on suitable raoketa se; 11 on one of t e side walls adjacent the floor. The coils are preferably supplied y with steam from any suitable source of sup ly which furnishes the required heat and rthe t'proper temperature maintained with- 1, in e room by a controlhng valve 19 auto'- lpectaeation of Lettera Patent. application aiea april is, isis. semi ne. escasa sired.

matically vcontrolled from a suitable thermostat. 13. The required humidit may be maintained Aby opening the han operated valve 14 located in a 'pi e 15 connected with the coils, throu h whic steam may be admitted to the interior of the room, if delieated by the coil will rise and the air along the floor of the room will flow toward the coil to replace the heated air, a circulation within the room being thereby set up. In order to further assist in the maintenance of the proper circulation of air I have mounted on the opposite side of the room from the heating coil a cooling coil -16 through which cold water or brine is circulated by any suitable mechanism. The air .which is cooled by the coil 16 will, of course, drop to the bottom of the room where it will flow along the door to the o posits wall to be heated by the coil 10, w ereupon it will rise again. A continuous circulation of air is thereby maintained within the room and the articles or material located therein will be dried under the most favorable conditions.

. Many articles and materials such fas macaroni and other flour products can not be dried under a high temperature because of certain chan y which take place in their structure'an compositionwhen subjected to hi h heat. The rapidity, therefore, with l.w ich said articles can-be dried under moderate-temperature will depend upon the rapidity of the air circulation within the drymi room. Other articles auch as leather, ru ber and various pigments which also reuire a low drying temperature need to be ried relatively slowly in order to prevent crackin of the surface or injurv to the article. t is essential, therefore, if the .room is to b e used for various articles that the circulation b e regulated to conform to the par tisular article being dried. It will be manifest that the rapidity of the circulation will depend u 0n-the height of the cooling coil 16 above he floor, since the higher the coils are located the faster the cool air will fall and .the more rapid will be the circulation within the room. I, therefore, prefer to mount the cooling coil brackets 17 upon upright pilas or standards 18 and to support the brach ts at the required hei ht by ad` justable collars 19. The ends of t e coil are connected with-the cooling liquid supply by flexible tubing 20 or suitable flexible pig:

which will t the coil to ad) ust to various-heights on the standards' 18. n the vdrawings the cooling coil is shown -in lines as adjusted to a position n ear e ceilm which will produce a rapid circulation an in dotted -liiies as ad'usted to a position near the tioor which wil produce a. much slower circulation. Manifestly the coil may be positioned at any intermediate point to produce the circulation required for the most successful drying of any particular article or articles or material.

I have found that by simplly adjusting the height of the cooling coil t e circulationof couplin air within the d ing room may be regulated struction considerable modification without departing' toatine degreeo nicet without the employn ieiit of fans, forced rafts, or other expensive and complicated mechanisms or structnres and my improved room uipped as above described may bc`untilized or successfully dryin articles or materials of widely different c aracters. In soine instances where rtiarticiilarl delicate articles are to be.

dried may ound desirable to position a small screen in front of the heating coil to'prevent direct radiation from the coilto the articles but, ordinarily, such a screen is unnecessary. Many variations in details of constructi will readily su themselves to those skilled in e art ut it will be understood from the foregoing that the illustrative conshown and described is capable of from the .spiritofthe invention or sacrificing any of the material advantages thereof.

I claim:

l. A drier comprising a closed dryin chamber having means for creating am maintaining a complete circuit of air circulation within the drying space of said closed chamber, said means including a heating device within the drying s acc and at one of the u right sides-only o the chamber, and a coo ing device within the drying space and at the opposite upright side only of the chamber with its coo ing surface in direct contact with the air of the drying space, substantially as described.

2. A drier comprising a closed drying chamber having means for creating and maintainin a complete circuit of air circulation within the dr ing space of said chamber said means inc uding a heatinfr device within the d ing space of said hambcr, and a cooling evice within the drying space of said chamber with its cooling surface in direct contact with the air of said drying ace, and means whereby one of said devices ma be supported at different eleva tions to c ange t e rate of circulation of the air, substantially as described.
