Specification of Letters Patent.

Application filed March 20,1905 Eerial No. 251,132.

To all mil/017a it may concern:

Be it known that we, LEROY B.- Fnnuon oi the United States, residing at Colun'ibus, in the county A is formed the compartment in which L of Franklin and State of (,lhio, have invented certain new and us'etul improvements in Gas Heating-Stoves, of which the following is a specification.

Our invention relat s to a new and-useful improvement in gas heating-stoves.

The object of the invention is to produce a simple stove oi superion construction wherein the products are caused to pursue an upend-down course before escaping; from the stove, and thus being thoroughly to prived of their heat.

Another feature resides in roducts as they pass upi iron urner, then distributing a drum, from which they are (1 vii down on opposite sides oi the heater to a compartment bottom, where they are again collected.

at the and allowed to escape into the 'fumopupc.

the provision Still another feature lies in of means for taking care of the back draft or pressure and drawing oil the fumes, which would otherwise escape form the heat r into is used.

Finally, the object of the invention is to provide a heater of the character described that will be strong, durable, and ellicient, simple, and comparatively inexpensive to make.

With the above and other objects in view the invention consists of the novel details of construction and operation, a preferable cur-- bodiment of which is described in the specification and illustrated in the accmnpanying drawings, whercin-- i Figure 1 is a iront elevation Fig. 23 is a side elevation. Fig. 33 is a longitudinal vertical sectional view taken on the line is :1; of Fig. 2, and Fig. 4 is a transverse vertical sectional view taken on the line 'y y of Fig. l.

In the drawings the numeral 1 designates the base in which chamber or compartment by a bottom plate 2, extending horiaontally across the base below its top. A central tube or flue 3 passes snugly through the top of the base i and rests upon the torn plate 2,"which latter is central opening-4, concentric with the flue I) and slightly smaller than the same. 5 projects through the opening and into the lower end of the tube. "lhe burner may be of any suitable construction and is conbot- 1 formed with a r r burner l l l l l nocted with a horizontal fuel-supply pipe 6, which extends from beneath the base and carries at its outer end an ordinary mixing-valve 7. The flue 3 is provided with a lining of asbestos or other suitable material 8, which tends from the bottom to about inidwa the height thereof. Fitted within the upper end of the lining an inverted tunnel E oni which extends a short pipe it) otsmaher diameter than the flue 3. The uppeend of the line 3 is closed by the bottom of a flat drum ll. The short pipe ll) communicates with and enters the uni through its bottom, so to deliver the products thercinto. The drum upports on the under side of its top a defect i eplate l2, which causes the products and al prcvents overliesting,- oi

being two on each side. These lines coininunicate at their lower end with the chamher A, which chamber is formed at its'rear' side-with an outlet or escape opening surrounded by a collar 1. A vertically-extending fume-pipe 15 is connected with the collar and issupported at its upper end bye bracket 16, which is suitably secured to the rear side of the drum ii it will be obvious that the products of combustion delivered into the drum ll will be damn down through the sevrufrtl side tubes or lines l3 into the (Llltlllk her A, from wan-h they will pass out through the collar i l and into the "Iume'pipc 15. The lumepipe 15 is DIOVlClCd a short distance above the top oi the drum ll with a suitable da lnper 17, which maybe turned to retard the draft or upward {low of the products, and thus cause the said products to thoroughly circulate through the heater. When the damper 17 is turned horizontally in the lumepipe 15, it may at some times retard the dral tor passage of the r'odiurt lo such an e.- tent as to lorcclh 2 some backward and cause a back pressure or back llow ol the l'umr-s, and should any portion oi the fumes be forced below the burner through the opening they will enter into a pan l8, supported on tical tubes or side lines 13, there preferably will be apparent that the llO the bottom plate 2, and pass out of the same into a by-pipe 19, which extends up the rear side of the fume-pipe 15 and enters the same at a point above the d ampcr, thus causing the said fumes to be delivered into .the iume-pipe and drawn off. By this arrangement the fumes are prevented from escaping into the compartment or room in which the heater is used, and the same may be employed with perfect safety.

The central tube 3 is provided a short dis tance above the top of the base 1 with a transparcnt door 20, whereby access may be had to the burner 5 for lighting and cleaning the same and also for the purposes of Having now fully described our invention, what we claim, and desire to secure by Let tors Patent, is t l in a heater of the character described, the combination with a central fine and a burner associated therewith, of means arranged in the flue for collecting and direct ing upward the products of combustion. from the burner, a drum communicating with the said means, side flues for carr ing the products downward from the drum, a compartment provided with an outlet and comn'iuni- I f eating with the lower inspection.

ends of the side fines, and means for leading ofi the back pressure or retarded fumes which pass below the burner.

2. In a heater of the character described, the combination with a central flue and a burner, of a collecting device arranged in the central flue above the burner, a drum having communication with the said device, vertical side flues extending downwardly from the drum on each side of the central flue, a compartment communicating with and connected to the lower ends of the side flues, a fumepipe leading from said compartment, means means for conveying the back-pressure fumes from about the burner and delivering them into the fume-pipe above the said retarding means.

In testimony whereof we aflix tures in presence of two Witnesses.
