`HOT-Alli.` CASING FOR HEATING SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 714,724, dated December 2. 1902- Application filed July 30.1901. Serial No. 70,201. (No model.)

.[0 all whom it Wtcty concern:

Be it known that I, EDWARD J. MALLEN, a

` citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Hot-Air Casings for Heating Systems, of which the following is a specifioation.`

My invention relates. to a knockdown casing for surrounding a steam-heating coil having the usual holes for the entrance of cold air and the exit of heated air for house-warming purposes.

The organization comprising the invention consists of the combination of a top sheet adapted to be suspended from an overhead support and having a pair of parallel depending flanges surrounding its edges, a second sheet formingbottom and sides of the casing and having its edges projecting between said projecting iianges and secured thereto by pins passing transversely through said edges and one of said depending iianges, end pieces having likewise double flanges formed on their edges, enabling them to surround the lateral edges of said second sheet and to form an airtight joint, and pins passing transversely through saidlateral edges and one of the flanges and securing the ends to the other casing-sections.

The further nature and scope of the invention are defined in the appended claims.

Figure lis a side elevation of the metal casing with a portion of the side broken away to show the interior construction. The figure includes a beam in the building, to which the construction is fastened. Fig. 2 is a Vertical central section of the left-hand end of the construction. Fig. 3 is a similar section of the right-hand portion. Fig. 4 is a plan of the whole device with a portion of the supporting-beams. A part of the top sheet is broken away to disclose the interior. Fig. 5 is an exterior or plan of an end piece for the casing ready to be applied thereto. Fig. 6 is a similar View of the other end piece. Figs. 7 and 8 are different yiews, on an enlarged scale, of one of the details ofthe construction. Fig. 9is a longitudinal Vertical sectional view through the center of the casing with the heating-coil removed.

Dotted lines in all the figures represent hidden parts.

The device consists of the combination of a top sheet A, suitably of galvanized iron, with downwardly-turned edges B at the sides and CA at the end at right angles to the plane of the sheet; verticallyhanging rods D, suspended from the beams E; adjustablecollars F, with set-screws G, for supporting said sheet against or just below said beams E; an angleiron rectangular frame riveted to .said top sheet A, whose sides which hang down and are lettered I-I at the sides of the casing and whose sides at the end of the casing are lettered I, said frame extending around the edges of said top sheet, so as to leave a distance between the frame and the downwardlyturned edges B and O about equal to the thickness of the sheet-iron, said rods D being terminated by eye-rings K; horizontal rods J, passing through said rings in pairs and held therein by nuts L on the ends `,of said horizontal rods, which are for supporting the coil of steam-pipe; a sheetM of galvanized iron below and substantially parallel to the horizontal rods J and bent vertically upward to forni the opposite side N of the casing, said sides terminating between two of the downwardly-bent edges of the top sheet A of the casing, respectively, andthe outside of the angle-irons I-I at two of the opposite edges of said top sheet A, to which angle-irons the said sides of the casing are detachably secured by split pins O, the said sides and bottom sheets projecting farther horizontally than the top sheet; an end sheet P, with its top edge between the downwardly-turned edge C of the top sheet A and the end angle-iron I, and said end sheet having three of its edges bent outward at right angles and lying against the inner surface of the side and bottom sheet and bent over to and lying against the outside surface of the said side and bottom sheet, and the said end sheet having an opening for the admission of cold air; a second left-hand sheet P', with its top edge lying between the` downwardlyturned edge O of the top sheet A and having its other three edges turned off to overlap the end of the sides N and the bottom M, and angle-irons R, riveted to the three edges of said second end sheet and bearing against IOO the innerl surfaces of said side and bottom sheet, and second end sheet P', having an opening at S for the exit of the air heated by said steam-coil.

The operation consists in selecting the proper size of the casing elements from those in stock, applying the hanging rods D to the beams E, slipping the top sheet A, with its angle-irons I-I and I, over the rods D, then supporting said sheet by means of the adjustable collars F and set-screws Gr, placing the upper edges of the sides N underneath the downwardly-turned edges B, fastening the sides N to the angle-iron II by the split pins O, slipping the upper edge of the end sheet under the downwardly-turned edge C at the right-hand end, fastening the end sheet P to the angle-iron I by split pins T and to the side N by split pins U and the bottom plate or sheet by split pins U', applying the other end sheet in a similar manner and fastening by split pins V. To take the device apart, the operation is similar except reverse. The coil of steam-pipe is supposed to be supported upon the rods J.

Each eye-ring K consists of a ring provided with a tapped nut K and screwed upon the rod D, which may be cut off and threaded at the right length while putting up the casing.

I claim as my invention- 1. A hot-air casing for heating systems comprising a top sheet having a depending flange surrounding its edges, a second sheet forming bottom and sides, and other sheets forming ends of the casing and having tongues upon their edges interlocking with said flange, and a parallel flange secured to one of the pieces and overlapping the joint, whereby to prevent the escape or entrance of air.

2. Ahot-air casing forheatingsystems comprising a top sheet having a depending flange surrounding its edges, a second sheet forming bottom and sides, and other sheets forming ends of the casing and having tongues upon their edges interlocking with said flange, a parallel flange secured to one of the pieces and overlapping the joint, and pins passing through the tongue and said overlapping flange, whereby to secure the parts in position and suspend the side, end and bottom sheets from the top sheet.

3. A hot-air casing for heating systems comprising a top sheet adapted to be suspended from an'overhead support and having a pair of parallel depending flanges surrounding its edges, a second sheet forming bottom and sides of the casing and having its edges proflanges formed on their edges enabling them to surround the lateral edges of said second sheet and to form an air-tight joint, and pins passing transversely through said lateral edges and one of the flanges and securing the ends to the other casing-sections, substantially as described.

4. In a hot-air heating system, the combination of hanger-rods adapted to be suspended from an overhead support, heating means suspended therefrom, a top sheet of a heating-casing having a pair of parallel depending flanges surrounding its edges and through which said hanger-rods pass, collars adj ustably mounted on said hanger-rods directly beneath said top sheet and upon which the latter rests, a three-sided sheet forming sides and bottom of the casing and whose top edges project between the flanges of the top sheet, pins passing transversely through said top edges and the adjacent flange to support said second sheet in position, a rear end sheet whose top edge is similarly secured between the depending flanges of the top sheet and which has similar parallel flanges projecting from its side and bottom edges embracing the corresponding edges of the side and bottom sheet and attached thereto by means of pins, and a front end sheet whose top edge is likewise secured between the depending .flanges of the top sheet, and whose other three sides are provided with an outwardly-extending saddle-flange embracing the lateral edges of the side and bottom sheet and secured thereto in a similarmanner by means of pins, the

whole forming a heating-casing of four sheets secured in position and forming air-tight joints.

5. In an air-heating casing for hot-air systems, a joint comprising a pair of parallel flanges on one part, a tongue on another part interlocking between said flanges, and fastening means passed transversely through said tongue and one of the flanges, substantially as described.

In testimony whereof I hereunto sign my name and afx my seal this 27th day of July, 1901.

y EDWARD J. MALLEN.
