W. L. HAGER Jan. 8, 1935.
Filed March 5, 1952 Patented Jan. 8, 1935 UNITED STATES PATENT OFFICE 1,981,145 CIRCULATING HEATER William Louis HagergOgden, Utah Application March 5, 1932, Serial No. 597,070
4 Claims. (01. 126 90) I This invention relates to an improvement in circulating heaters.
The object of the invention is to improve the manner of heating air and circulating it into and through a room.
, My heater is constructed with a series of vertical air tubes through which the airto be heated passes, and from these tubes the air is deflected into the room by baffle means extending over the tubes. Circulating heated air from a burner is passed about the tubes, and by means of baflles is circulated lengthwise of the tubes in a zigzag route to eflfectively heat the air passing through the tubes. I I
The accompanying drawing is a vertical sectional view through the complete heater.
The casing of my improved heater is designated generally by the numeral 1, and is provided with a perforated cover 2 at the front thereof, for the passage of the heated air into the room. The back of the casing 1 is preferably set into a wall 3 of the room, and through which Wall a discharge vent 4 may extend in the form shown, which vent communicates through a passage-way 5 in the back of the casing with a heating chamber 6.
The heating chamber is provided with a bottom 7, and a zigzag top wall 8 for closing the same. Baflle-plates 9 extend in opposite directions from the bottom and top plates '7 and 8 toward, but spaced slightly from, the opposite plate; and these bathe-plates 9 provide a zigzag or circuitous passageway through the heating chamber 6.
Tubes 10 extend vertically entirely through the heating chamber 6, being supportedby the bottom and top walls 7 and 8, and communicate with the spaces below the bottom wall and above the top wall, but being closed with respect to the heating chamber 6. These tubes 10 are of different lengths, as required by the zigzag top wall 8, so that the upper ends of the tubes are in stepped relation, which it has been found materially increases the radiation of the heater.
Arranged above the tubes 10 are deflecting baffles 11 curved toward the front of the heater for directing the heated air through the perforated cover 2.
A combustion chamber is shown at 12, below the heating chamber 6 and communicating with the front thereof. A burner 13 is located within the chamber 12, and is adapted to be controlled by a pilot 14 located beside the burner. An air tube 15 directs air into the combustion-chamber 12, where it is heated by the burner 13, and is then forced into the front of the heating chamber 6, through which it passes in a circuitous manner to the back of the chamber, where it enters the lower end of the vent 5.
As the air passes in a zigzag direction through the heating chamber 6, it circulates around the 5 tubes 10 which pass therethrough and efiectively warms the air which is passing through the tubes. The arrows in the drawing show the direction of the passage'of the heating air through the heating-chamber 6, and the passage of the heated air 10 through the tubes 10 and into the room.
In order to maintain a proper degree of humidity in the air, I have provided a humidifying pan 16 attached to the front wall of the heater, and which is adapted to be maintained partially full 16 of Water to be vaporized by the passage of the heated air thereover.
The vaporizing-pan 16 is adapted to be connected with a water main, and to control the height of water in the pan I have shown a float 20 controlled valve which may be used therein. A valve casing 17 is fixed in the pan 16 and has a valve therein, controlled by a float 27, which regulates the flow of water into the humidifyingpan 16 and maintains a predetermined water level therein.
In order to provide a proper circulation of air through the tubes 10, I have shown a fan 29 in the drawing, the motor 30 of which may be controlled by thermostatic switch means designated 30 generally by the numeral 31 in the drawing.
The fan creates and maintains the desired circulation of air and may be placed at the proper point to draw cold air from the room through the suitable cold-air ducts in or near the floor, and 35 which air is then passed through the tubes 10 and heated, after which'it may be returned to the room, thus keeping up a circulation by removing cold air which normally is at the lower part of the room, and replacing same with heated air.
In this Way, I have provided for the supply of heated air to a room with proper control by a thermostatic control for the fan, which forces the circulation of the air, and provision is also made for automatically supplying the proper degree of humidity to the air being circulated.
The character of the heater is such as to provide a maximum degree of radiation, and without the circulating air coming in contact with the products of combustion. The air from the burner, which is used to heat the circulating air, does not gain access to the interior of the room, and yet its heat is eflectively utilized for heating the circulating air by passing the latter through the tubes in the heating-chamber, and by circulating the air from the burner in a circuitous or zigzag manner lengthwise of the tubes.
I claim: 7
1. A heater comprising a casing having a heat= ing chamber therein, air tubes extending through said heating chamber and supported by the easing, the upper ends of the air tubes being in stepped relation and being successively higher from the front approximately to the rear, and means extending upwardly and forwardly over said tubes for directing the heated air forwardly therefrom.
2. A heater comprising a casing having a heating chamber therein, top and bottom headers for said chamber, air tubes extending upwardly through said chamber and having their opposite ends connected with the headers, means for heating said chamber, the upper ends of the air tubes being in stepped relation and being successively higher from the front to the back, and a deflecting bafiie extending upwardly and forwardly from the top header for directing the air forwardly from the upper ends of the air tubes.
3. A heater comprising a casing having a heating chamber therein, top and bottom headers therefor, air tubes extending entirely through memes the heating chamber and having their opposite ends connected with the headers, bafies extending in opposite directions from, and attached to, the headers forming a zigzag heat passageway through the heating chamber and about the air tubes, a combustion chamber communicating with one end of said passageway, a duct communicating with the opposite end of the passageway, the upper ends of the air tubes being in stepped relation and being successively higher from front to back, and one or more deflecting bailies extending upwardly and forwardly from the top header and curved for directing the air forwardly from the upper ends of the air tubes.
4. A heater comprising a casing having a heating chamber therein, top and bottom headers therefor, air tubes extending upwardly through the heating-chamber .and connected with the top and bottom headers, said air tubes having their upper ends in stepped relation and being successively higher from front to back, an outlet at the front of the heater, and a baflie for directing the'heated air from the stepped upper ends of the air tubes forwardly through the outlet.
