\ Application May 6, 1933, Serial No. 669,651 r ;4 Claims. (01.257-139) This invention relates to heat interchange'rs and more particularly to steam radiators and the like.
The principal object of this invention is to provide a radiator of 'efiicient design and pleasing appearance.
Anotheriobject of this invention is to provide a radiator of sheet metal construction.
A further object is to provide a radiator efficient in operation and economical to manufacture.
A still further object is to provide a radiator having a large radiating surface while occupying a relatively small space.
Another object of this invention is to facilitate i5 .the'manufacture of radiators of this type. by providing a radiator constructed, of several pairs of identical parts.
Further objects will appear herein.
In present practice, heat interchangers generally and particularly steam radiators and the like are ordinarily constructed of cast metal, each radiator usually being cast in a plurality of small sections, said sections being assembled and secured to each other by means of bolts, etc., in order to provide a chamber of necessary capacity and a suitably large radiating surface. This method of constructing a radiator has long been recognized as being expensive both in the casting of these sections, and also in the assembling of the sections to construct the completed radiator. Various attempts have been made from time to time to provide a radiator of a sheet metal construction, but none of these have heretofore been highly satisfactory. In the various attempts to provide a radiator of a sheet metal construction, a number of dimculties have been encountered,
the principal difliculties being that the formation of the sheet metalplates used have been somewhat complicated, and therefore expensive to manufacture, and difficulties have been encountered in sealing these plates to each other and to an inlet and outlet means for steam.
Another difiiculty that has been encountered in some of the attempts to provide a radiator of sheet metal construction is that these radiators, as heretofore designed, have been constructed of a large number of separate pieces, and have therefore been expensive to assemble. The present invention provides a radiator of sheet metal construction, which solves the difficulties just mentioned by reason of the fact that it is economical to manufacture and is composed of a relatively small number of pieces in such a manner that they may be easily manufactured and assembled.
Referring now to the drawings in which I have illustrated the preferred embodiment. of this invention:
Fig. 1 15 a front elevational view of this radiator and its associated fittings. Fig. 2 is an end elevation showing this invention as viewed from the 5 right hand side of Fig. 1. Fig. 3 is a top plan of the preferred form of this invention. Fig. 4 is a fragmentary plan section taken substantially on the plane of the line 4-4 in Fig 1. Fig. 515 a detail section taken substantially on the plane of lo the line 55 in Fig. 1. Fig. 6 is a detail sectional view illustrating the means used herein for securing and sealing the sheet metal plates of this device to provide a steam chamber. Fig. '7 is an enlarged plan section of the operative parts of this device. Fig. 8 is an enlarged plan section similar to Fig. 7 showing a slightly modified form of plates. Fig. 9 is a fragmental detail section of another modification of this device.
Referring now particularly to Figure 1, the steam supply pipe 10 is provided with the usual valve 11, the outlet of this valve 11 being connected to an elbow 12, screw threaded to the lowermost end of an inlet pipe 13. This inlet pipe 13 is provided with a longitudinal slot 14 to provide a passageway for the steam between the inlet pipe 13 and the radiator proper. The radiator proper consists of two sheet metal plates 15 and 16, these plates being corrugated as shown in Fig. 7, and being spaced apart by spacing rods 17 and 18 at their top and bottom edges. By an examination of Fig. '7, it will be seen that the plates 15 and 16 are of identical size and shape, and that when reversed from one another as shown in Fig. 7, their configuration is such that they will lie spaced apart equidistant at all points, and provide a continuous circuitous steam passage 19 of uniform cross-sectional area. The spacing rods 17 and 18 are shaped to conform to the shape of this passage 19, and it will be seen that these spacing rods 1'7 and 18 are also identical in size and shape. As seen in Figs. 5 and 6, these spacing rods 17 and 18 are positioned at the extreme uppermost and lowermost edges of the plates 15 and 16, and are secured thereto by any suitable means, such as welding, as at 20, Fig. 6. Having been thus sealed at the top and bottom by the spacing rods 17 and 18, the plates 15 and 16 may then be inserted in the slot 14 of the inlet pipe 13 and may be secured to the inlet 50 pipe 13 by any suitable means such as welding as indicated at 21, (See Fig. 4). It should be understood that the slot 14 in the inlet pipe 13 is of a suitable length to exactly fit the assembly of plates 15 and 16 and spacing rods 1'7 and 18, 55
and that the welding 21 will therefore serve to connect the steam passage 19 with the inlet pipe 13 and seal this passage from the outside atmosphere. At the end of the radiator, opposite the inlet pipe 13 is a slotted outlet pipe 22 which is identical in every respect with the inlet pipe 13, and is provided with a slot 23 by means of which the assembly of plates 15 and 16 and spacing rods 1'7 and' 18 is connected, as just described. At the lower end of the slotted outlet pipe 22, there is provided an elbow 24 by which the radiator, is connected to the customary trap 25, and return pipe 26. The upper ends of the inlet pipe 13 and the outlet pipe 22 are provided with caps 27, which serve to seal the upper ends of these pipes. Immediately below the plates 15 and 16 there is provided an ornamental grille 28 through which the inlet pipe 13 and the outlet pipe 22 may pass, and this ornamental grille 28 is held in position by means of the elbows l2 and 24 as shown in Fig. 1. Immediately above the plates 15 and 16, there is provided another ornamental grille 29, which is identical to the grille 28, and which is held in position by means of the caps 27 as shown in Fig. 1. Legs 30 are provided to support the radiator and these may be secured to the lower side of the grille 28 by any suitable means.
From the foregoing description, it will be seen that the radiator, as just described, will be economical to manufacture since it is assembled by means of a simple welding operation, and by means of threading the elbows 12 and 24, and the caps 27 on to their respective inlet and outlet pipes 13 and 22. It should also be noted that each of the individual parts used herein, is used in pairs, and this fact results in a much more economical method of manufacture as will be well understood in the art. In Fig. 9, I have illustrated a slight modification of the ornamental grille 29 in that I have provided it with an upraised portion 31 in order that the top surface 32 of this grille may be substantially on a plane with the top surface 33 of the caps 27.
While I have described the preferred form of this invention, it is capable of numerous modifications, and should not be limited except as by the appended claims.
I claim the following:
1. A heat interchanger comprising a pair of plates, spacing rods united with said plates and serving to seal their two opposite edges to form a. chamber, slotted inlet and outlet pipes adapted to communicate with this chamber, pipe fittings secured to these inlet and outlet pipes, and ornamental grilles secured to the inlet and outlet pipes by means of their associated pipe fittings.
2. A heat interchanger comprising a pair of plates, a steam chamber formed by said plates, pipe fittings communicating with said steam chamber, and ornamental grilles secured to aforementioned plates by means of said pipe fittings.
3. A heat interchanger comprising a steam chamber, ornamental plates associated therewith, pipes adapted to pass through openings in said plates and communicate with the steam chamber, and pipe fittings adapted to secure said plates to the pipes.
4. A heat interchanger comprising a steam chamber, ornamental grilles positioned at two opposite sides of the steam chamber, a pipe adapted to communicate with the steam chamber and to extend between the two ornamental grilles, and pipe fittings associated with said pipe in a manner to preventthe displacement of the omamental grilles.
