cluding valvesfand pipes, but preferably it leaves the ittings projecting as illustrated.

`The casing is open at levels above the top of the radiator proper for the discharge of heated air and also at levels below the radiator to take in cool air.- In the cases illus-v `rated the bottom of the casing is open for admission of air, but the admission opening might be arranged at the front or the ends below the ievel of the inlet to the radiator lues.

In 1 there is a front discharge through the upper portion of the front panel and in Fig. 3 the discharge is through the top of the casing.

In Fig. 1 the casing has a closed ltop wall 5,-end walls 6 and a front wall or panel 7 at the upper edge of which is located a perorated plate or grating 8 for emission of the heated air. f

The end walls 6 are provided with oblique slots 9 open at the rear edge to permit passing of the latter across a projecting pipe such as `the inlet pipe 10. Asiinilar oblique slot at the lower part of the oppositeend Wall accommodates the outlet `pipe 11.

The casing may be long enough to enclose the projecting pipes and fittings. It may also extend clear down to the floor. In fact its proportions may be variously altered. An illustration of such modificationsk is not attempted, since they do not affect the invention. l

According to Fig. ,3 the front panel 7 is closed clear to its upper edge and the top 12 is perforated to permit the escape of heated air. Y

lt is assumed in the specific cases illuslevel from the wall and is carried up to the valve 17 which leads to thepinlet pipe 10 of the radiator.

The casing is a unitary transportable structure applicable to the radiator after the latter has been installed and adapted to be supported by the radiator; so that, vwhen the latter is suspended abovethe floor as indicated, the lower edge of the casing may also clear the floor.

The casin may be simply and economically made of s eet metal, such as copper, brass or steel, grained to harmonize with the furniture or woodwork in a room, or painted so as to harmonize with the color of the wall orM decorated 'according Ato any desired scheme.

In applying the leasing to the radiator, nothing more is necessary than to slip it in place by a downward movement over the top of the radiator. It Vprotects the radiator against injury.-

vThe Murray radiators referred to are generally made of extremely thin copper or other sheet metal which is liable to distortion by a slight blow so that a protective casing is particularly useful with this type of radiator. The material and method of production make it possible to manufacture the casing very cheaply. A

The top plate 12, Figs. 3 and 4, has va rear flange 18 bent down sufficiently to embrace the'rear face of the radiator. End flanges 19 are bent down to fit against the outer faces of the end'walls G. A front flange 20 is bent down and preferably-'molded into'a graceful shape to overlap'thefront panel 7. The end plates' are similarlyflanged and bent over to form stiffening moldings 21. And the lower edge of the front panelis formed with a corresponding molding 22. The centre of the front panel may be further 'ornamented and stiifened as desired.

The top, ends and front panel are readily stamped out and bent to the flanged and molded shapes described. They arethen assembled in a jig and spot welded or otherwise firmly jointed. The molding at the lower edge of the panel may be integral with the panel, as in Fig. 4, or a separate strip welded to the sheet as injFig. 7. The casing is intended to fit fairlyclosely' about the radiator. It should also be held firmly against displacement thereon.

Where a top-discharge of the hot air is permissible, as in the usual location immediatel below a window, the casing may rest direct y on top of the radiator, as in Fig. 4. Where a front-discharge of hot air is desired, Fig. 6, the top has a depending flange 23 at the back, atr the lower edge of which is an angle iron 24, a flange of which projects over the top of the radiator. The angle iron is secured to the plate 23 and may extend along the entire length vthereof or may be in slliort lengths located at intervals along the p ate.

To prevent longitudinal displacement of the casing with relation to the radiator, the front panel 7 has securedto it near its ends, vertical angles 25 (Fig. 5) whose inwardly projecting flanges bear against transverse fins 2 of the radiator. To prevent the lower free edge of the front panel frombecoming bulged or otherwise distorted in time, it is preferable to fasten it also to the radiator. This is done by clips, such as are shown in Fig., 7 embracing theedge of the panel and also embracing the lower end of a longitudinal web 3 of the radiating structure. There may be two of these clips, one at each end of the panel, or more, if the panel be of consi lerable length.

' The clip is of spring metal with a hollow centralfportion 26 adapted to embrace the edges of the parts. An inner flange 27 facilitates introducing it over the web 3. An outer flange 28 is shaped to fit the molding 22 on the panel and to permit the forcing of the clip up over this molding. Thin spacer blocks 29 are introduced between the panel 7 and the web 3 to hold the parts rigidly and at a determined slight distance apart. 0r the spacers may be omitted and the clips proportioned so as to clamp the plate 7 against the webs 3, as shown for example in Figs. 5 and 6. And, in general, the variations shown in detail in each of the several figures are applicable to the styles of casing shown in each of the other figures.

It will be observed that the transverse fins 2 of the radiating structure form alternately flues which are closed by the outer webs 3 and channels which are closed on three sides, but open on the outer side. lVhen the casing is applied, the front panel thereof substantially or approximately covers the outer sides of these channels and converts them into flues closed in cross-section. Such flues have an important function in securing a very rapid heating and circulating effect by the induced draft of the heated air.

wWhether the lradiator be suspended above the floor or supported thereon, the casing should haveits lower edge clear the floor or have openings at or near the bottom for admitting air to the lower ends of the radiator flues Aand channels. The invention may be applied yalso to radiators supported by legs resting on the floor. And, however the radiator is supported, the pipes may pass through the floor and directly upward to the valves.

i The slots in the end walls may be of various other shapes than that shown. For example, they may extend horizontally inward from the'edge and then upward.

Various other modifications may be made by those skilled in the art without departing from the invention as deiined in the following claims.
