ApplicationI filed January 19, 1909. Serial 11o. 473,208.

To all whom 'it may concern:

Be it known that I, CHARLES E. DE Fon- REs'r, citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

The purpose of this invention is to supply a device for heating rooms, apartments and other` quarters, designed either for abode or assemblage, which will utilize the fuel to the best possible advantage and insure a circulation and distribution of the heat.

A .further purpose of the invention is to provide a heater of the type using fluid, as fuel either in the liquid or gaseous state, Iaccording to the type of burner employed.

The invention also has for its object todevise a heater of the variety aforesaid admitting of the burner being easily and quickly removed and again placed in position to meet existing conditions without necessitating separation or dismemberment of the body portion of the heater.

The invention also aims to sup ly a heater which is portable and capable ofp generating a maximum amount of caloric to .be effectively used for raising the temperature of a room or other place. desired to be heated.

For a full understandin p of the invention and the merits thereof an also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following. description and accompanying drawings, in which:

Figure 1 is a vertical transverse section of ahea'ter constructed in accordance withv and embodying the essential features of this retainin invention; Fig. 2'is a central vertical secv tional view looking toward the front of the in all the views of the drawings by the same reference characters.

The heater comprises a fire box or combustion chamber 1 which may be of any size ofconstruction and upon legs 2 of any design or pattern. The fire box is contracted at its .upper end and provided with outer flanges 3 and ,a vertical flange 4, the flange 3 being rabbet'ed at its outer edge and supporting an apron 5, which acts bot as a fender or guard land adds to the finish of theheater, since it may be ornamented in any way, either by relief work or by being plated, or by a combination of both.

The bottom 6 of the fire box has a central opening 7 and both vertical and pendent flanges, as clearly indicated in the several views. A series of rlbs 8 are formed upon the upper side of the bottom 6 and serve to strengthen the same and to hold the burner elevated, so that air may circulate beneath the burner to properly support combustion and equalize distribution of the heat. A cross piece 9 extends across the opening 7 and is provided at a central point with an opening to receive a in 10. A cam 11 surrounds the opening o the cross iece and is placed upon the top side thereo and serves as a means to effect vertical movement of the pin 10. A plate 12 is located beneath thebottom 6 and adapted to close the opening 7 thereof, or to regulate the amount of air entering the heater. The pin 10 is mounted in the opening of the cross piece 9 and passes through an opening of the plate 12 and is formed with a shoulder 13 iipon which the plate 12 rests. The lower en of the pin 10 is provided with a suitable finger piece to admit of turning the pin when required to effect vertical adjustment of the plate 12. A stop 14 near the upper end of the pin 10 rests upon the cam 11 and coperates therewith to effect vertical movement of the pin 10 and plate 12 when said pin 10 is rotated. The bottom 6 is provided exterior to the large opening 7 with a series of smaller openings 7 for the ingress of air into the fire box or combustion'chamber to msure proper working of the heater.

The body of the heater comprises an air-I shaft 15 and inner and outer casings 16 Iand refcrably mounted lower portion of' the air-shaft 15 passesy through the fire box, as indicated most clearly in Figs. 1 and 2. The casings 16 and 17 terminate at their lower ends in the plane of the top of the fire box and are supported upon-the outer flange 3. The lower end portion of the air-shaft 15 is contracted, as indicated at 18, and is of a length approximating the height of the fire box, the lower end of the'fcontracted portion 18 surrounding the opening 7 of the bottom 6 fitting within the vertical flange surrounding the opening 7. lThe upper end portion of the air-shaft is similarly contracted, as indicated at 1 9, and makes close connection with the upper plate 20 which joins and properly spaces the parts 15, 16 and 17.

Opposite walls of the air-shaftfas the front and back, are reversely bent to provide an extended heat? radiating surface. The side walls of the air-shaft arepreferably straight, since they are comparatively narrow. The air-shaft may be constructed in any manner and by preference is. formed of similar sections whichare jointed -at 'their sides, the meeting edges being provided with outer flanges 21 which are fitted together and receive the securing means, such as rivets or bolts. The flanges 21 do'not extend the entire lengthof the air-shaft, but terminate a distance from the up er and lower ends thereof and form in effect ribs which touch the side walls of .the casing 16 and subdivide the space into two vertical passages, as indicated a't 22' and 23 for a purpose presently to be explained. A flange 24 extends laterally and rearwardly from the lower rear portion of the air-shaft and is inclined from front to rear and closes the lower end of the rear passage 23. The flan e 24: acts as-a deflector and vis `preferably ormed with the -rear portion of the air'shaft as a part thereof.

The central portion of the upper plate 20 is formed with an opening 25 and upper and lower flanges surround said opening,

the lower flange making connection vwith the upper contracted end 19 of the air-shaft and retaining-the same in place. The upper flange surrounding the opening 25 forms la raised seat upon which a plate 26 is adapted to close. The outer portion of the plate 2O is stepped and receives the upper ends of thecasmgs 16 and 17 which make close connection therewith. The middle portionof end of the air-shaft and the upper end of the casing 16 is solid, so as to completely close the upper ends of the passages 22 and 23. The rear portion of the plate 20 ex? tending-Jover the spaceor duct 27 formed between the rear portions of the casings-16 and 17 is .solid to close said space at its downv through passage 23, through openino' :amount upper end. The part of the late 20 closing the space or duct 28 forme between the front and side walls of the casings 16 and 17 is provided with a series of openings 29v to establish connection between the said duct 28 and the intermediate chamber 30 inclosed by the top 3l fitted to the upper end of the heater.

a series of openings 32 are formed for ythe outflow of -the heated air. An opening 30 is provided in the upper rear portion of the casing 17 anda is surrounded by means of a collar 33 to, which a stove-pipe may be .fitted for carrying oft the products ofy combustion resulting from the burner when the heater is in operation. An opening 34 lis provided in the lower .rear portion of the casing 16 and establishes connection between the lower ends of the passages 23 and 27;

The lower end of the space or duct 27 is The space or duct 28 is closed at its lower end by the outer flange 3 in which to effect vertical adjustment thereof. Thel upper or projecting end of the set screw 35 may be ornamented in any way. The

plate 26 is directed in its vert-ical movements by means of guide pins 36 which operate in openings 36 1n the plate 20,.'the latter being formed with openings to receive said guide pins which project from the plate 26.-

The burner 37 may be of 'any type using fluid as fuel, whether liquid or gaseous.

The burner is preferably formed of sections which are connected by interlocking joints 38, thereby admitting of the burner being easily and readily removed from the heater or placed in position Without requiring the heater to be taken apart. vThe burner occupies a position in the lower fire box and rests upon the ribs 8 provided upon the upper side of the bottom 6.

ortion of the When the heater is in operation the hot i air and products of combustion resulting from the burnerv 37 vwhen lighted, Apass upward into the firebox, thence through the space or passage 22 surrounding the front portion of the air-Shaft,- thencearound the upper contracted end 19 Vof the air-shaft 34 'intothe space or duct 27,'thence u War therethrough andoutthrough the out et 30' vto be carried of by means of a fsmokepip'e,

not shown, Ato a' convenient point of disother place to be heated. It will be observed that by setting the plates 12 and 26, which are in eii'ect dempers, a comparatively small amount of air may be admitted into the lower end of the air-shaft, which becoming heated is expanded before reaching the outlet at the upper end of the airshaft and is further expanded b its passage through the duct 28. B c osing the opening 7 air may be prevent from entering the air-shaft, thereby maintaining the heater in a warm condition for a comparativl great len th of time after the burner has een close It will be observed that the burner is readilyv accessible by lifting the upper portion of the heater from the base o r by removing the same through an o 'ening provided in a side of the tire box, tie sectional formatioi of the burner admitting of the separation of the parts, so asto clear the'lower end portion of the airsha-ft.

A The seating faces of the plates 12 and 26 are" provided with asbestos or like material 26 to insure a elo/se tit when said plates are f is vclaimed as new is:

closed upon their respective seats. This obviates the necessity of rinding or tiling.
