r Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed June 14, 1907.1Serial No. 378,969.

To all whom it may concern:

Be it known that I, PHILIP NEHLIG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Gasstove, of which the following is a specification.

My invention consists of a gas stove composed of a casing, an air flue, a burner and a diaphragm in said casing adapted to direct the products of. combustion in a circuitous direction or course from the burner employed to the discharge flue, thus obtaining an increased heating action of the products of combustion and consequently producing a greater volume of heat, the means employed being hereinafter described, and the novel features pointed out in the claims.

Figure 1 represents a vertical section of a gas stove embodying my invention. Fig. 2 represents a horizontal section on line w-m, Fig. 1. Fig. 3 represents a horizontal section on line y-@ Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings :A designates the casing of the stove, and B designates a flue, shown as tapered with the larger end uppermost, adapted to receive air which is to be heated, as will be hereinafter more fully described, said flue being open at top and bottom, the air, in the present case, being admitted thereto by means of the branch or supply pipe O, which is connected with the bottom of the flue.

The top of the casing A is closed by the wall D, and the bottom thereof is provided with the plate E, which is partly perforated, so as to admit air to the burner F within the casing A, said burner having connected with it the pipe Gr, whereby it may be supplied with gas for evident purposes.

l/Vithin the casing A below the exit flue H, is the horizontally extending diaphragm J, which is of the form of the segment of a circle and has between its ends the passage K,whose position is at the front portion of the stove, opposite to, or comparatively disposed to said exit flue thus forming a communication between the upper and lower portions of the interior of the casing, while the dia phragm cuts-off such communication, it being noticed that said diaphragm closely engages the walls of the casing A and fine B, and is firmly secured thereto.

The portion of the casing A above the diaphragm J forms the chamber L, which is in communication with the portion of the interior of the casing or chamber M below said diaphragm and at rear with the exit flue H.

The operation is as follows:Air is admitted into the flue B from the bottom thereof, and gas admitted to the burner F. The gas is ignited, and the products of combustion rise in the chamber M of the casing A and heat the same and the flue B, whereby the air in the latter is highly heated and discharged insaid condition into the apartment, the latter being heated also by the heat radiated from said casing. The products of combustion instead of being discharged directly into the exit flue H, is deflected by the diaphragm J to the front of the chamber M, from whence they are directed through the passage K to the chamber L, and then traverse the latter rearward to the exit flue H, by which provision the products of the combustion have a circuitous course from the burner F to the front of the casing, and then to the rear thereof, and thus there is an increased heating action of said products, both on the flue B and the top and side walls of the chamber L, so that said products are utilized to an increased extent, and the stove is rendered most effective in producing heat, both from the casing A and the flue B. The perforated plate E rests on the spider or open frame N and is contained within the peripheral flange P thereon, said flange engaging the inner face of the lower end of the casing A. In the center of said spider is a collar Q in which the lower end of the flue B is seated and in the center of the cap plate or wall D is a collar R with which the upper end of the flue B engages, said fine-thus being firmly sustained at both ends. Bolts S pass through the spider N, plate E, and wall D and the body of the casing, thus firmly connecting said parts. The base T of the easing is adapted to have the legs U of the stove connected therewith in any suitable manner.

While I have specified certain means for carrying out my improvements, I do not wish to be limited exactly to the same, but desire to make such changes as may come within the scope of the novelty involved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a. gas stove, a casing having a base ortion le s secured to. said basev ortion an open frame having a peripheral 'flang'e engaging the inner face of the lower end ofi. said casing above the base and a central collar, a perforated plateresting uponthe horis zontal portions of said peripheral flange and" collar within'said open frame, a flue having" its lower end received within said collar,

a supply pipe beneath said base and having. an upwardly extended portion received within the lower end of said flue, a closure for the upper end of the casing, an outlet therefrom a horizontallydisposed diaphragm below said outlet through which said supply tubeextends said diaphragm having a segmentali opening at the front of the stove and aburner within. saidcasing above said perforated plate and surrounding the lower end of said flue.

2. In a gas stove, a casing, an open frame, the base of the casing sustaining'said frame,- said frame having a collar centrally thereon and a flange on the periphery thereof,.a gas: burner in said casing, a perforated; plate which is rested on said open frame withinsaid flange, an air flue of tapered form with its larger end uppermost, said fluebeing held frictionally in the plates at top and bottom, the lower of whiclrlatter is. seated in said collar, an exit fiueon said casing-,a plate closing'the top of said casing, said diaphragm within said, casing snugly embracing said airline below'said exit flue, the sam e.,;having a passage therein substantially opposite to said exit flue, and means for fastening said frame and plate to thecasing.

3. In a gas stove, a casing, an open frame, the base -of'the casing sustaining said frame, said'frame having a collar centrally thereon,

burner in said casing, a perforated plate which is supported on said open frame within saidflange, an air-tight flue extending entirely through said casingfrom topto bottom and-tapered inwardlyfrom its upper to its lower end, the lower end of saidtlue beingseated in said collar and frictionally held, an exit flue on said casing, a plate closingthe top of the-casing, said-plate having centrally thereon a collar in which the upper end of said flue isfrictionally and Wedgingly contained, aninlet flue having a vertical portion received in the lower end of saidair-tight flue, a diaphragmwithin said casinglbelow the'exit flue and having a passage'therein on the side of the air flue oppoe site said exit, and means for securing the parts together.
