' AIR HEATER.

Application led August 25, 1924. Serial No. 734,057.

ments opening outside said tank, alternately, the ones at the bottom and at the top on the left hand side (Fig. 1) and the others at the top and at the bottom on the right hand side (Fig. 3). The first ones allow the passage of the gases moving upwardly and constitute the gas-compartments, while the latter ones allow the passage of the air moving downwardly and constitute the air? compartments. The heating fluid and the .heated fluid are therefore travelling as a counter-current on both sides ofthe sheet iron plates separating the same, according to the accompanying drawing, in which the arrows inffull lines indicate the direction followed by the gases, and the arrows" in dotted lines, the way followed by the air. v

In this' drawing: Fig. 1 is a vertical section made through a gas-compartment and on line 1-1 of F ig. 2.

Fig. 2 is a vertical section on line 2-2 of Fiv'. 1.

Fig. 3 is a vertical section made through an air-compartment and on line 3--3 of Fig. 2, tubes being shown as substituted for the bars.

Fig. 4 is a horizontal section on line 4-4 of Fig. 1.

Fig. 5 F i0'. 2.

Fig. 6 is a similar view on line 6-6 of Fig. 3.

In this drawing, 3- indicates the two exis a similar view on line 5-5 of ternal sheet-iron plates of the tank or chest.

4 are the internal sheet-iron plates; 5, the bordering or edge frames made of U-shaped iron or angle-iron.- 6 are the bolts and t1erods connecting and fastening the whole.

The chest or tank is located within a brick-work or sheet-iron lue.

This air-heater is more particularly charac'terized by the fact that the exchange of heat is eiected mainly by transverse bars 7, the few lsheet-iron plates 4, which are separated by large spaces, assisting very little in the heat exchanging.

The bars 7 present not only a larger heating surface than the sheet iron plates 4, but as they are arranged normally according to vthe flow of the hot gases 4and. m qumcunx order saidr gases are constantly eii'ectively mixed and come in contact with all the pomts of the lbars,.whilst the gases strike the sheet iron platesv 4 in' horizontal direction so that only thelayers of gas on the two sides of the gas flow come in contact with said plates.

The, heat-evolving bars 7 consist of round solid bars, as shown'in Fig. 1, or of thick tubes, as shown in Fig. 3. They pass through the internal sheet-iron plates 4 which are for this purpose provided with holesl of the same diameter as the bars, which are located exactly the one opposite lthe other and regularly arranged in quxncuhxorder or -so that the bars in one horizontal row stand e next lower and .next upper horizontal row. They abut against the external plates 3 which are solid or plain.

These bars 'can be made of a 'single piece or of several parts, the breaking section being in this case always 'located close yto the middle of the interspaee between two internal sheet-iron plates 4. v lThe Hue gases flowing through the gascompartments 1 heat the transverse bars 7 which transmit the heat to the' air which Hows through the air compartments 2 in a direction opposite the direction in which the gases flow.

' Conductivity is the main quality of the bars in question. Accordingly, these bars must e made of metal, and more particularly, whenever itis possible, of metals having a high heat conductive power.

It will ofcourse be understood that these bars can be used in connection with other devices allowing the exchange of temperature between gaseous fluids.

The vertical tubes 8 are used for sweeping purposes. They are secured to the middle part of everyone of the gas compartments.

and are provided, at the height of every horizontal row of heat-evolving bars on either side with a small hole through which is sprayed the steam or compressed a1r stream which drives away the soot and other matters. .The tubes 8 are branched upon a common pipe-9.

An air-heater comprising in combination parallel sheet iron plates widely spaced and forming alternating passages for flue lgases open at the lower end in the,k bottom olpposite the intervals between the bars in t1 end of the heater and at the upper end in one side of the heater, and passages for the air to be heated open at the lower end in the side of the heater opposite to the side on which said gas passages terminate and at the upper end in the upper end of the heater, and horizontal metal bars arranged in quincunx order traversing said parallel plates and heated by said gases in the gas passages to transmit the heat to the air in the air l0 passages. l

In testimony whereof I affix my signature.
