UNHTED J'ULIUS JUIDELSON, 0F NEW YORK, N. Y.
DRIER.
Application ledi'luly 28, 1923. Serial No. 654,362.
To all whom t may concern:
Be it known that JULIUs JUDnLsoN, a citizen of the United States, residing in the city of New York,'in the county of Bronx and State of New York, has invented cer-V tain new and useful Improvements in Driers, of which the following is a specification.
This invention relates to improvements in driers. More particularly' it isl directed to a drier of the vcharacter described adapted for use in apartment houses where the driers ordinarily employed have a plurality of separate drying compartments. i
One object of the invention is, to provide a drier of the character described with a heating apparatus having separate heating units so constructed and arranged as to permit of heating one or more compartments separately or one or more palrs of compartments separatelyor heating a plurality of compartments simultaneously.
Another object is to provide heating apparatus of the character described which shall utilize to a maximum degree the heat units from the burner or burners, and insure an even temperature throughout the interior of the drier.`
A further object is to provide apparatus of the character described which shall insure a proper and eiiicient circulation of dry heated air through the drier'so as to rapidly and uniformly dry the articles or material therein without injury thereto, the
lgases of fumes from they heating apparatus being kept from direct contact with the interior of the drying compartment.
A still further object is to provide ina drier of the character described, aheating apparatus which shall be efficient and economical in operation to a'high degree andl will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims. i
In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,
Fig. l is a sectional plan view of one double heating unit; y ,Y t
-Fig. 2 is a view in vertical longitudinal section through a portion of the drier casv lng and through the heating unit, the section through the latter being taken on line 2-2 of Fig. l;
Fig. 3 is a view in front end elevation tition 3 is provided to divideeach double` compartment into separate drying chambers. y j A,
Each double compartmentnis providedl in its lower portion with a vdouble'heating unit A, which serves to heat both chambers, of the double compartment, and which will now be described in detail. l ,y
Each double heating unit A comprises an elongated flue box 4, of general V-shape in plan at its forward end,and havingalongitudinaly partition 5 therein which is ofl general V-shape at its rear end, andcooperates with the V-shaped forward end of the box to divide the box into a pair of relatively long flues 6.. i` y In the forward portion of each `flue 6 av gas burner 7 or other heating element is located, said burners beingV controlled "byr cocks 8 and supplied with lfuel by a-'pipe 9.
Within each double compartment of-ftheL casing l, and at the rear thereof,.I provide a relatively wide box l0 extending into the adjacent drying chambers and which is perforated in its vfront and bottom as shown at 11. This box 10 is provided .onfits top at its center with a tapering outlet l2 and the latter communicates at its upper end with a chimney 13.
A. vertical pipe 14- is connected by a Y- coupling 15 with the inner ends of the pair of flues 6 and projects upwardly through the box 10 and terminates in the tapering outlet 12 thereof.
On top of the flue box A. and directly above each flue 6, return flues 16 are located. These return fines are preferably of box like form, appreciably smaller in diameter than the ues 6, and preferably of inverted V- shape in cross section. Openings 17, 17 are provided in the top of flues 6 connecting thelatter withthe return flues 16, and these openings are spaced an appreciable distance from the ends of the flues.
Forwardly and downwardly curved baffles 18 are provided in the fines 6 below the openings 17 to properly direct the circulation of air, and it will be noted that the reariopenings 17 and battles 18 are larger than the forward openings and bailles, to insure best results.
Each Vburner 7 is provided with an elongated baflie 19 above the same. These baffles are'preferably inverted lv' -shape in cross section, and are supported on brackets 20 resting upon burner platforms 21. The heater is supportedabove the floor of the casing 1 on legs 22 or other suitable mounting.
YThe forward end of each flue 6 is provided with a screenedy air inlet door 23 to admit the` necessary air to aid combustion, andv for circulation through the apparatus.
.In each of the single compartments of the drier casing 1, are suitable supporting racks 24eI for the articles or material to be dried, andeachy double heating unit serves to heat and dry the articles in two of these single compartments, as will now be explained.
'The operation is as follows Alir enters the forward end of the flue 6. Some ofthi's air is used up in combustion in the`burners, but the main portion thereof is heated by the burners to the desired temperature so as to providea circulating heating 'medium which circulates through the flues- 6`l and 16 and transmits its heat to the air` in the drying vcompartment above the heating units. The heated air flows through iiie-Gtowards the rear end thereof where ati" the `opening 17 a large portion thereof passes through said .opening into the flues 16 and is returned into flue 6 through the opening 17 at the other end fori-@circulation. Some of the air in flue 6 passes directly into the Y-coupling 15 and thence upward through pipe 14 into the box outlet 12 and up the chimney 13. The recirculated, heated air is reheated as it passes over the tlue 6 and near the burners and then passes out through the rear end of the flue 6 in the manner just described. The direction of the flow of air is indicated by the arrows in Fig. 3.
The upward draft in the chimney 13 effectively aids this circulation and at the same time draws the moisture. laden air in the drying compartmentsthrough the openings 11 of the box 10, thus exhausting the moist air through the chimney 13, as will be readily understood.
It will be understood, of course, that each heating unit may be operated independently, or all of the heating units` operated simultaneously as desired.
lt` will be noted that the heating apparatus is a separate and distinct unit spaced and sealed from the drying compartment so that none of the gases or noxious fumes or vapors coming from the fabrics enter the drying chamber, thus eliminating all possible injury therethrough to the materials or articles being dried.
l have found that with the apparatus above described very efficient, rapid and economical drying compartments may be effected with the maintenance of a uniform temperature throughout the drying compartments.
1t will thus be seen that there is provided apparatus in which the several objects of this invention are achieved and which is well adapted to meet the conditions ofv practical use. i
As various possible embodiments might be made of the above invention, and as various changes might bey made in the embodiment above set forth, it is to be understood` that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limitingsense.
Having thusA described my invention I claim as new and desire to securel by Letters Patent:
1. ln a drier a heating unit, comprising an elongated box, a longitudinal partition in the box dividing the-same into,` a pair of main lues, and a return flue on top of the main fiuesand communicating therewith.
