STOVE OR H EATIN SPECIFICATION forming part of Letters Application filed April 22, 1398.

- heating=stoves, are frequently required to consume on occasion from five to ten times as large an amount of fuel as at other times. At the same time such apparatus are expected to admit of being easily attended to without requiring any special skill on the part of the attendant.

This invention has for its object to meet the above requirements, and is hereinafter de scribed with reference to the accompanying drawings, in which- Figure 1 is a vertical section of a stove constructed according to this invention; Fig; 2, a

horizontal section on line at a of Fig. 1; Fig. 3, a horizontal section on the line 3 y of Fig. 1. Fig. 4 is a plan view of one of the grates.

The heating apparatus comprises a fuel-receiver 1,provided with the usual bottom grate 2, ash-pit 3, feed-tube 4, and line 5. Upon one portion of the fuel-receiver gratings 6, usually inclined, are so arranged that a continuous row of hollow spaces 7 is formed which spaces are separated from oneanother' partly or entirely, by thin layers of fuel. The number of these hollow spaces or combustionchambers is equal to that of the gratings plus one. The first space or chamber is formed between the lowermost inclined grate 6 and the bottom grate 2, while the lastspace or chamber is formed above the topmost grate 6. The feed-tube 4 may be constructed in the form of a cylindrical grate, as shown in Fig. 1 in dotted lines. The remaining part of the fuel-receiver is constructed as smoothly as possible, so as to enable the coals to easily descend and so that, apart from the hollow spaces above referred to,-no further spaces or chambers are formed.

Patent No. 627,643, dated June 27, 1899.

SerialNo- 678,479. (No model.)

According to Fig. 1 each combustion-cham= her 7 may be provided with an air-valve 8-. When the coal or fuel is kindled upon the bottom grate, the gases are caused to traverse all the hollow spaces, thus heating the fuel within or in contact therewith, so that on subsequently opening the air-valves the fuel becomes ignited, whereby, if so desired, its combustion may be obtained throughout the hollow spaces or chambers. The heating-gases .Will always travel through the gratings instead of passing through the intermediate spaces formed between the fuel accumulated in the fuel-receiver. Consequently the combustion will not materially extend into the fuel-column, so that the fuel serves as an ef= ficien't medium for preventing the walls of the receiver from being burned. By means of the air-valves the heating capacity of the stove admits of being varied within very wide limits, and the temperature can be easily so regulated that the walls forming the combustionchambers are likewise prevented from overheating.

The heating apparatus is especially suitable for burning fuel which ispoor in gas, in which case the produced gases are instantly consumed by the flames in the chamber 7, while the temperature, without attaining a degree such as to injurethe walls of the apparatus,

can be exactly-so adjusted that a complete combustion is obtained.

What I claim, and desire to secure by ters Patent, is.-

l A stove or heating apparatus comprising Letthe fuel-receiver 1, a bottom grate 2, and a JESS ADOLPH JENSEN.
