DBYING- DEVICE.

Application le'd March 24, 1924.I Serial No. 701,544.

To all whom it may concern:

Be it known that I, JOHNA S. RoNEY, a citizen of the United States, and resident of Middletown, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Drying Devices, of which the following is a specification.

My invention relates to devices for drying damp articles, such' as laundry work, clothing` lumber, paper, etc., by means of a forced draft or drafts of heated air, or gas, and my purpose is to provide a device of this kind that is of simple, comparatively inexpensive construction, and that is rapid, safe and thoroughly reliable and efficient in operation. l

' iVith the foregoing and other purposesv in view, my invention consists in the novel features7 of construction, combination and arrangement. of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the separate views their upper iFigure 1y is a vertical section through a dryinY device embodying the novel and essenta features of my invention, said section bein taken approximately on the line 11 of ig. 2; and

Fi re 2, a horizontal section taken ap.- proximately on the line 2-2 of Fig. 1.

The device of my invention which consists essentially of a receptacle to receive articles to be dried and means for forcing heated air or gas therethrough thereby to dry articles contained therein may be formed from any desired material into any desired size and sha e, but 'for the sake of convenience is s own in the present instance as formed from sheet metal and of rectanguiar shape in which embodiment it is composed of a basevlO., a coolingdevice or devices 11 rising from said base and enclosing one or more sides of the receptacle, a hinged door 12 providing a closure for one side of the receptacle, and a top 43, the device being comparatively air-tight when closed. t

Base 10 is in theform of a pen having upstanding side walls 14 terminating at ends in turned {ianges 15 on which the bottoms of the cooling device or devices 11 rest, whereby said cooling de- (supplied to and removed air or vice or devices are supported above the bottom wall of the base, and the dome-like top 13 is secured to the u per ends of the cooling device or devices w ereby the device as a whole is made rigid, strong, and comparatively airtight.

Each cooling device 11 consists of a cooling jacket 16 surrounding a vertical space 18 which space communicates at its lower end with the interior of the base 10 and at its upper end with the interior of the receptacle, cooling water or other `iiuid being from said jacket in any preferred manner as by means of pipes;v 17

Between the cooling device or devices 1l and the receptacle proper is a lining 19 of sheet metal or other suitable material, which lining is open at its top where '1t is provided with outwardly directed flanges 20 resting on the upper end of the cooling device or dcvices and at its bottom vis closed as at 21 and extends into the interior of the base 10. lt also is open at its front where it is provided with flanges 22 secured against the forward edges of the cooling device or devices and b v inea-ns of the flanges 20, 22 its sidewalls are maintained spaced from the inner walls of the cooling device or devices as shown.

In the bottom wall 21 of lining 19 is an opening or openings 23 arranged toadi'nit air or eas from the interior of the base 1t), and a fan or fans 24 of any suitable type is or are provided to force air or gas through said opening or openings into and through vthe receptacle, while within the receptacle,

slightly .above the bottom wall of lining 1f). is ascreen 25 of wire mesh or other suitable foraininoiis material adapted to direct thev forced air-or gas currents prior to the .saine entering the receptacle in such a manner as to prevent dead spaces in the receptacle.

lVithin the base 10 is one or more heaters 26 of any suitable'type adapted to heat the as before it lis forced through the screen eflector to the receptacle by said fan or fans, whereby heated air or gas is supplied to the receptacle for drying articles contained therein, said' heaters preferably being located below the fans whereby the air or gas is treated before it passes through the fan or fans. Y Y

Any suitable means such as brackets or the hangers indicated generally at 27 may be provided within the receptacle to sup- `shown within the spirit port articles therein to be dried, and as indicated by dotted lines at 28 in Figure 11 of the drawings a partition or partitions may be provided to divide the receptacle into compartments whereby certain articles to be drie may be maintained separate from other articles to be dried.

At the bottoms ot the cooling device ordevices 11, adjacent to the walls thereof defining the spaces 18, are short extended flanges 29, the purpose of which, is to direct condensate Waters forming on the inner Walls of the cooling device or devices into troughs 30 disposed beneath the openings 18, said troughs serving to cause such water to flow to a suitable drain (not shown) and the device thus maintained substantially free of moisture.

The method of using my device as Well as its Inode ot operation is apparent and as follows :-Tl1e door 12 is opened and the Wet or damp articles to be dried are placed Within the receptacle on the hangers 27' or otherwise disposed, after which the door is closed and the heaters and fans 26 and 9.4 are set into operation to respectively heat the air or gas within the base and :torce it through the receptacle and through the articles contained therein. As the heated air or gas `passes through the receptacle it absorbs the moisture from the articles and in a moisture laden condition it passes through the spaces 1S surrounded by the cooling jacket or jackets 16 where itcontacts .with the relatively cold surfaces of the cooling device or devices and the moisture therein is thus pre` cipitated therefrom. The precipitated moisture collects on and flows downward over the inner surfaces ot the spaces 1S and drips from the flanges 29 into the troughs 30, being conveyed away by said troughs as pro viously' indicated. The air or gas now being cooled passes again into the base 10 where it is, reheated and again forced by the fans 2=lthrough the receptacle, the operation ol drying thus utilizing the sanne air or gas over and over and being continuous as is apparent.

From the foregoing description considered in connection with the accompanying drawings, it is believed that the construction, operation and advantages of my device will be apparent. It is desired to point out, however, that various changes and desirable additions maybe made in and to the structure and `scope of my invention as defined in the appended claims.

I claim 1. In a device of the character described, a base, 'areceptacle above and communicatingat its bottom directly with said base, a cooling device at the side of said receptacle having a passage therethrough communicatlng at its bottom with said base and at its top with said receptacle, heaters arranged within said base, and means also arranged within said base for forcing heated air therefrom through said receptacle.

2. In a device of the character described, a receptacle adapted to receive damp or wet articles to be dried, means for forcing heated ar or gas through said receptacle thereby to dry articles contained thereirna coolinfr device for precipitating moisture from said air or gas, after the same has been forced through said receptacle, means to convey the moisture precipitated from said air or gas to ya point of discharge, and flanges ,on said cooling device or devices to direct moisture precipitated from .said air or gas into said conveying means.
