Application filed October 11, 1916. Serial No. 125,055.

I l To all whom at may concern:

vide a device of this character which will be portable and household uses.

The invention has as a further object to provide a heater of such construction that either an oil or gas burner may be employed in connection therewith and wherein a shelf will be provided for supporting the burner particularly adapted for with the shelf adjustable with respect to the heating drum to accommodate the different types of burners.

And the invention has as a-still further object to provide a heater of this character having a plurality of bafile plates so arranged within the heating drum that the, heat risin within the drum will be intensified by owing over the said plates and whereln the said plates may, when desired, be removed. I 4

Other and incidental objects will appear as the description proceeds and in the drawings wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a perspective view of my improved heater, r Fig. 2 is a sectional view more particw larly showing the construction of the heating drum as well as the adjustable mounting of the burner supporting shelf,

Fig. 3 is a similar view showing the mounting of the battle plates within the heating drum of the device and also illustrating.

the use of a gas burner in connection with the heater,

Fig. 4 is a detail perspective view of one of the baflle plates,

Fig. 5 is a simllar view of the spreader employed to cooperate with the said plates, Fig. 6 is a sectional view particularly showing the arrangement of'the flue leading from the burner into the heating drum, and

Fig. 7 is a sectional view showing the ad'- justable'connection between the burner supporting shelf and the posts or standards for the heating drum. I

lln carrying out the invention, the device is formed with a suitable base 10.to which lsconnected a plurality of supporting legs. Rlslng from the base are a plurality of posts 11 arranged in triangular relation and recelvlng at their upper ends, a heating drum 12. The drum 12 may be formed of sheet metal or other approved material and is preferably of cylindrical formation with conical upper and lower terminals or ends 13 and 14 respectively. The upper terminal 13 of the drum is, at its inner extremity, provided with a radial flange 15 preferably ternnnating in a suitable ornamental roll and this flange is arranged to seat upon a similar flange 16 carried by the body of the drum, drawings. Detachably connecting the said flanges are a plurality of bolts or other suitable fastening devices 17. The upper end of" the drum is thus detachably connected to the drum body, and, at the smaller terminal wall 18.

Fitted through the end wall 18 of the upper terminal of the drum .to extend axially within the said drum is a hanger including a. rod-19 upon which is mounted a plurality thereof, is provided with a. perforated end of perforated bafiie plates 20. These plates are, as shown in detail in Fig. 4 of the drawings, preferably in the nature of metallic disksand are supported in vertical spaced relation upon the rod by spacer sleeves 21 surrounding the rod. Adjacent the upper end of the drum, the rod 19 is also equipped with a spreader 22, this spreader being, as shown in detail in Fig. 5 of the drawings,

formed by an imperforate metallic disk.

Screw threaded upon the extremities of the rod 19 are suitab e nuts for holding the disks 20. the sleeves 21 and the spreader 22 in po sition upon the rod with the uppermost sleeve 21 frictionally engaging the wall 18 of the upper endef the drum for supporting the hangerupon the drum. In this connect tion, attention is directed to the fact that the disks carried by the said hanger gradually increase-in diameter from the lowermost disk to the central disk and then gradually decrease in diameter to the baffle plate 22. The rod 19, at its upper end, is normally provided with a suitable ornamental ball. 23 but should it be desired to employ a vessel in connection with the heater, a warming plate 24 is provided, as illustrated in Fig. 3 of the drawings, the ball 23 being dis placed and the plate 24: being screw threaded as best shown in. Figs. 2 and 3 of the s upon the upper endof the rod '19 to receive the vessel,

= The lower terminal 14 of the drum is open at its smaller extremity and is provided with a depending-flange to which is suitably at- -tached, as. by a bayonet slot connection as illustrated in the drawings, a conical cap 3 'Slidably adjustable through the smaller 1 end of the cap is a flue 26 provided at its with a flangev 27 .for holding" the flue against outward displacement with 'the flue normally extending axially within inner en v the drum. Any suitable type of burner may 'be arranged upon the shelf and in Figs.

1 and 2 of the drawings, I have shown acon- -'ventional type of oil burner 31 mounted upon the shelf with the chimney of the'said burner received within the flue 26 while in Fig. 3, l have illustrated the shelf as equipped with burner 32 with the cap of the drum removed and the shelf adjusted to dispose the said burner in the lower end. of the drum. The advantage in adjustaloly mounting the shelf 28 thus becomes apparent since it will be seen that the shelf may thus be positioned for properly supporting either an oil or gas burner with respect to the drum. When an oil burner is employed as illustrated in'Figs.

1 and 2, heat from the said burner will rise Q. vergin'g walls of the upper through the line 26 to be discharged against the lowermost bailie plates 20. Upon flowing over and through'the perforations in these lowermost plates, the heated currents will be intensified and will be directed thereby outwardly toward the sides of the heater until the said currents strike the largest centrally disposed plate. The conterminal 13 of the drum will then tend to direct the said I drum will .be materially heated currents inwardly against the uppermost baflle plates to pass therethrough and be further intensified until the said currents strike the spreader 22 to be again deflected against the sides of the drum whence the said currents may issue through the upper end wall 18 or discharge terminal of the drum. The sides of the drum will thus be eflectually heated while, at the same time,

the heated currents in passing through the intensified to conmquently enhance the efi'iciency of the a conventional type of gas panacea heater. Should it become necessary to displace the bafiie plates, the upper terminal 13 of the drum. may be readily disconnected for this purpose.

As will now be observed upon particular reference to Fig. 2 of the drawings, the burner F31 may be removed from the shelf 28 by simply sliding the flue 26 upwardly within the drum to clear the chimney of the sa1d burner. This provides a convenient arrangement whereby the burner may be easily displaced without the necessity of adustmg the shelf 2 8 so that upon the initial ad1ustment of the shelf, the flue 26 may be operated to clear the burner. In any instance where a gas burner is employed, as illustrated in Fig. 3, the flue 26 will not be needed, and the cap 25 is consequently removed for directly receiving the said gas burner into the lower end of the drum.

It will therefore be seen that I provide a very simple and efiicient construction for the purpose set forth and a device particularly adapted for household use. Accordingly, the drum is preferably provided with one or more .suitable handles 33 whereby the heater may be easily moved from place to I claim and desire to secure by Letters Patent is: I Y

A device .of the character described including a base, a heating drum carried by the base and adapted for circulation of heated currents therethrough with the said drum formed with a conical lower terminal, a cap closing the lower terminal of the drum, at its smaller end, a flue adjustable longitudinally through the cap with the cap removable for displacing the said flue, and a burner shelf mounted to support aburner to coiiperate with the flue for directing heated currents from the burner through the drum.

2. In a device of the character described, the combination with a heating drum contracted at its extremities and open at its ends, and a burner mounted at the lower end of the drum, of a plurality of superposed baflle plates supported within the drum and respectively decreasing in area toward lthe contracted extremities of the drum, whereby heated air currents entering the lower end of the drum" will be directed by the said plates in a circuitous path through the drum to be restricted at the upper extremity of the drum and discharged at the upper end thereof. i

3. In a device ofithe character described, the combination with a heating =drum formed with conical extremities and open at its ends, and a' burner mounted atthe lower end of the drum, of a hanger :projecting axially into the drum from the upper extremity thereof, and a plurality :of. flat disks mounted upon the hunger in super lltlt lltia axially through the said disks- PI'OViClHlg bafile plates within the memos:

posed relation with the hanger extending disks and with the drum, the said disks being of graduated diameter decreasiv g from the central disk in the direction of the lower conical extremity of the drum and decreasing in di- 'ameter from the central disk in the direction of the upper conical extremity of the drum whereby heated air currents entering the lower end of'the drum will be directed by the said plates in a circuitous path through the drum to be restricted at the upper" extremity of the drum and discharged at the upper end thereof.

AL A device of the character described ineluding aheating drum contracted at its upper extremity and open at the ends thereof, a burner mounted adjacent the lower end of the drum, and a plurality of battle plates of graduated area arranged within the drum with certain of the said plates disposed within the contracted extremity thereof" for directin heated currents from the burner in a clrcuitous path within the drum to be restricted within the upper extremity thereof by the contracted portion of the drum and directed out at its upper end.

In testimony whereof I aiiix my signature.
