HEATING APPARATUS.

Application filed Kay 10, 1924. Serial 80., 712,893.

To all whom it may concern:

Be it known that I, OSCAR VOIGT, a citizen of the United States, residing at Lyons, in the county of Wayne and State of New York, have invented new-an'duseful Im-.

provements in Heating Apparatus, of which the following is a specification.

My invention is a heating apparatus for boilers furnaces and the like and its prin? cipal' object is the provision of an attachment to bearranged in 'the fire-box of a conventional boiler to permit coal screenings and the like to be burned therein.

A further object is I lyprovide an attachment of the above cha acter which will 'adequately and completely burn coal screenings and other like cheap fuel andget the maximum amount of heat therefrom.

A still further objectQis'to provide a fur:

nace attachment having means for supplying and automatically regulating draft air to the/grate element which construction includes an apertured flat plate for receiving the fuel.

-With the preceding and other objects and' advantages in mind, the invention consists in the combination of elements, the con struction and arrangement of parts and operation to be hereinafter fully referred to,

claimed and illustrated in the accompanying drawing, wherein:

Fi re 1 is a perspective of the conventiona boiler equipped yvith my invention.

Figure 2 is a transverse sectionalview of the grate or fuel supporting means.

Referring in detail to the drawing wherein corresponding characters of reference designate corresponding parts throughout the several views, the numeral 5 designates a conventional boiler'havin theusual fire-box 6, and mounted on this oiler is the usual thermallfy operated diaphragm 7 including a horizontally arranged pivoted lever 8.

Arranged within the fire-box 6 isa pair of spaced parallel longitudinally extending angle bars or guides 9 and supported thereon is a grate element including a fiat perforated plate 10 upon which the coal screenings are placed. Arranged beneath the plate 10 is a. bowl or air receiving rece tacle 11 provided with lateral flanges 12 at its upper end which are received between the under.

face of the late 10 and the angle bars 9. A vertical tuh'e 12' extends downwardly and centrally from the .bowl 11," the lower end of this tube 12 being normally closed by a pivoted cutofl' or valve 13 secured in a manner to be moved in a horizontal plane and As shown in 'igure 1. this valve is arranged so that it can be conveniently reached from to form a tight connection with the tube.v

the clean-out door of the boiler and may be swung to one side for the purpose of permlttingthe small clinkers and foreign mat- ..ter which may sift through the apertures of the plate into the bowl 11, to gravitate into the ash chamber of the furnace. A conventional blower is designated at 14 and leading therefrom is a conduit 15 having communication with the tube 12' at a point above the valve 13. This blower 14 is driven by a conventional electric motor 16. An electric circuit is designated generally at 17 and included therein is a knife sw1tch'18 normally held in operative, position by a contractile ring 19 having one end fixed to the switc cured to a suitable base as at 20. A flexible element 21 is attached to the switch 18 and extends upwardly and is connected with the outer end of the lever 8 above mentioned.

Under ordinary conditions the blower supplies air to the bowl 11 and is discharged through the perforated'plate 10 below the coal screenings contained thereon or in other words creates suflicient draft to ade-.

quately burn or.c.onsume-the fuel to get the maximum When the boiler is heated sufiiciently to operate the thermal diaphragm 7 the lever 8 Band its opposite end seamount of heat therefrom.

will be moved upwardly and through the instrumentalit-y of the flexible element 21 the knife switch 18 will be disengaged from its respective contacts to stop t e rotation of the motor 16. However, as soon as the boiler has cooled sufficiently to permit the thermal diaphragm to return: to normal position, the spring 19 will return theswitch to its normal or operative position to again start the motor.

While I .have shown and described the preferred embodiment of the invention, it is to be understood that changes infthe arrangementofvparts'ma be made and that I am only-limited byt e appended claims,

Having thus described the invention, I claim:

1. An attachment of the character described oomprising a pair of parallel an 1e brackets adapted to be arranged in the fire box of a furnace, a perforated Slate adapted bowl arranged below the plate, a tube deformed on the upper end ofsaid bowl and pending rom the bowl and being in com- "being received between the under face of the 1 munication therewith, a valve controlling side edges of the plate and the angle brackthe lower end of said tube, and a blower ,in ets respectively, a tube depending centrally 45 communication with the tube and adapted from the bowl and being in communication to'supply draft air to the bowl and through therewith, a valve controlling the lower end the perforated plate. ofthe tube, and a blower communicating 2. An attachment for furnaces compriswith the tube in' a manner to provide draft "ing a pair of a le brackets adapted to be air to the bowl and to the fuel on the per- 10 associated with t e fire box of the furnace, forated plate.

- a, perforated plate supported by the brackets In testimony whereof I aflix my signature andfbeing adapted to receive fuel, a bowl 1 arranged below the plate, lateral flanges i OSCAR VOIGT.
