, Appuemmianumzzi, isiafseriamo; 73,132 f 22 claims. (01..110-1-97) vinvention -relates tto attachments Jfor roomor circulating `4heaters.

lIn lcirculatingheaters wherein the v@heater,-is y vused as al 'heatingmedium,v theoil` is fed toafdrum plied to conventional oil drums without the use of tools, the device being collapsible or foldable so that it may be passed through the front door of the heater.

Another object of this invention is to provide a device of this kind embodying a circular plate formed in two halves hinged together with supporting feet on the outer portions of the plate for engagement with the top of the oil drum, the plate being supported by the feet a predetermined distance above the drum and having a diameter substantially the same as that of the drum, so that the plate will be heated to a relatively high degree and will form a radiant heating medium in addition to deilecting the heat and names laterally toward the walls of the heater. y

A further object of this invention is to provide an attachment of this kind which is of simple and rugged construction and can be produced at small cost sor that it will not add unduly to the cost of the heater and can be purchased separately for mounting on a heater at present in use. Y

With the above and other objects in view, our invention consists in the arrangement, combination and details of construction disclosed in the vdrawings and specification, and then more particularly pointed out in the appended claims.

In Ythe drawing,

Figure 1 is a plan view, partly broken away yof an attachment for a circulating heater constructed according to an embodiment of this invention, showing the device mounted on top of the oil drum,

Figure 2 is a sectional View taken on the line 2-2 of Figure 1, with the drum removed,

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 1.

Referring to the drawing, the numeral I designates generally a circular plate which is formed oi.' a pair of semi-circular half members II and I2. The members II and I2- are provided on,

' their :router :marginal Vedges .with depending xanges I 4 1 and .r1.5 respectively ilfor `:reinforcing l.the @plate :members .L I I i and f I2. s'I'heratwo plate members. I I'fand.

I9: and' 2li,l and 2i andi-:22, respectively, 'which -are 'carried by vithefzsplate members II and I2. f f

In order to provide a means whereby the plate members II and I2 when in horizontal operative position may be supported above the top of an oil drum generally designated as 23 and of conventional construction, we have provided pairs of

feet

24 and 25 which are xed to or formed integral with the plate members Il and I2 and project both outwardly and downwardly therefrom. The

feet

24 and 25 are adapted to engage an annular rim or flange 26 which is carried by the top of the drum 23,being removably mounted on the rim 26 and held against lateral movement by extending downwardly a slight distance from the upper end of the drum 23. as shown in Figure 3.

The plate member Il is formed with an opening 21 inwardly from the marginal edge thereof and the plate member I2 is formed with a similar opening 28. rIhe openings 21 and 28 'are provided so that a. limited amountk of heat, names or products of combustion may pass through the plates II and I2.

In the use of this device, the attachment comprising the hinged plate members II and I2 may be mounted in a, heater of present construction by extending the plate members II and I2 through the doorof the' heater which opens into the repot. In most heaters of this type the door is round and of fairly small size and in order to position the attachment within the heater the two plate members II and I2 are rocked toward each other to collapse the device and allow for its being passed through the small door opening. After the device is within the heater, the two plate membersk II and l2 are swung outwardly to substantially horizontal alignment with each other, and the

feet

24 and 25, are kthen engaged y with the rim 26 of the drum 23.

The fuel is lighted in the conventional manner in the lower portion of the drum 23 and the ames or products of combustion rising in the drum 23 will pass outwardly inthe space 29 which is formed between the plate members II and I2 and the upper edge of the drum 23. A portion of the flames or products of combustion may also pass through the

openings

21 and 28. With an attachment as hereinbefore described, the flames generated in the oil drum 23 and rising from the open upper end thereof Will be deflected laterally toward the walls of the rebox so as to more thoroughly heat these walls than would be the case when the flames rise vertically upward from the top of thedrum 23.

We do not meanl to confine ourselves to the exact details of construction herein disclosed but claim all variations falling within the purview of the appended claims.

What is claimed is: 1. A deilector attachment for use in the upwardly opening oil drum of a circulating heater i of the liquid fuel burner type comprising a circular plate formed of semi-circular members, said members having transverse edges adapted for abutted engagement to form a, close fitting assembly, dependent flanges carried by the outerperiphery of said members, and feet members carriedby said plate having dependent portions that extend below and outwardly of said flanges for engagement with the drum to space said plate above and extending outwardly of the drum opening, said flanges extending about the semicircular edge of each member only, rwhereby when they are assembled in the manner recited a continuous circular flange about the entire assembly is thus formed.

4 2. An attachment as defined by claim 1 including apertures formed in the plate withsaid apertures equally spaced at each side of the abutted edges of the members to provide release means for hot gases pocketed within the flanges of said plate.
